    Objective The purpose of this study is to determine the frequency of adverse perinatal outcome in women with hyperemesis gravidarum and identify prognostic factors. Study design This is a case-control study in which outcomes of first pregnancies were compared between 254 women with hyperemesis gravidarum treated with intravenous fluids and 308 controls. Prognostic factors were identified by comparing the clinical profile of patients with hyperemesis gravidarum with a normal and an adverse pregnancy outcome. Binary responses were analyzed using either a Chi-square or Fisher exact test and continuous responses were analyzed using a t-test. Results Women with hyperemesis gravidarum have over a 4-fold increased risk of poor outcome including preterm birth and lower birth weight (p < 0.0001). Among maternal characteristics, only gestational hypertension had an influence on outcome (p < 0.0001). Treatment as an outpatient and/or by alternative medicine (acupuncture/acupressure/Bowen massage) was associated with a positive outcome (p < 0.0089). Poor outcomes were associated with early start of symptoms (p < 0.019), and treatment with methylprednisolone (p < 0.0217), promethazine (p < 0.0386), and other antihistamines [diphenhy- dramine (Benadryl), dimenhydrinate (Gravol), doxylamine (Unisom), hydroxyzine (Vistaril/Atarax), doxylamine and pyridoxine (Diclectin/Bendectin)] (p < 0.0151) independent of effectiveness. Among these medications, only the other antihistamines were prescribed independent of severity: they were effective in less than 20% of cases and were taken by almost 50% of patients with an adverse outcome. Conclusion Poor outcomes are significantly greater in women with HG and are associated with gestational hypertension, early symptoms, and antihistamine use. Given these results, there is an urgent need to address the safety and effectiveness of medications containing antihistamines in women with severe nausea of pregnancy. PMID:23751910

    CD47 is an antiphagocytic molecule that acts via ligation to signal regulatory protein alpha on phagocytes; its enhanced expression and therapeutic targeting have recently been reported for several malignancies. However, CD47 expression in gastric cancer is not well documented. Immunohistochemical expression of CD47 in surgical specimens was investigated. Expression of CD47 and CD44, a known gastric cancer stem cell marker, were investigated in gastric cancer cell lines by flow cytometry. MKN45 and MKN74 gastric cancer cells were sorted by fluorescence-activated cell sorting according to CD44 and CD47 expression levels, and their in vitro proliferation, spheroid-forming capacity, and in vivo tumorigenicity were studied. In vitro phagocytosis of cancer cells by human macrophages in the presence of a CD47 blocking monoclonal antibody (B6H12) and the survival of immunodeficient mice intraperitoneally engrafted with MKN45 cells and B6H12 were compared to experiments using control antibodies. Immunohistochemistry of the clinical specimens indicated that CD47 was positive in 57 out of 115 cases, and its positivity was an independent adverse prognostic factor. Approximately 90% of the MKN45 and MKN74 cells expressed CD47 and CD44. CD47(hi) gastric cancer cells showed significantly higher proliferation and spheroid colony formation than CD47(lo) , and CD44(hi) CD47(hi) cells showed the highest proliferation in vitro and tumorigenicity in vivo. B6H12 significantly enhanced in vitro phagocytosis of cancer cells by human macrophages and prolonged the survival of intraperitoneal cancer dissemination in mice compared to control antibodies. In conclusion, CD47 is an adverse prognostic factor and promising therapeutic target in gastric cancer. PMID:26077800

    The prognosis of leptomeningeal metastasis (LM) from solid tumors is extremely poor, especially for patients with adverse prognostic factors. In this phase II clinical trial, we evaluated the efficacy and safety of intrathecal chemotherapy (IC) combined with concomitant involved-field radiotherapy (IF-RT) for treating LM from solid tumors with adverse prognostic factors. Fifty-nine patients with LM from various solid tumors were enrolled between May 2010 and December 2014. Concurrent therapy consisted of concomitant IC (methotrexate 12.5-15 mg and dexamethasone 5 mg, weekly) and IF-RT (whole brain and/or spinal canal RT, 40 Gy/20f). For patients with low Karnofsky performance status (KPS) score and radiotherapy intolerance, induction IC (1-3 times) was given before concurrent therapy. Thirty-eight patients (64.4%) received subsequent treatments. All patients were followed up at least 6 months after LM diagnosis or until death. Primary endpoint evaluated was clinical response rate. Secondary endpoints were overall survival (OS) and safety. The pathological types included lung cancer (n = 42), breast cancer (n = 11) and others (n = 6). Median KPS score was 40 (range 20-70). Fifty-one patients (86.4%) completed concurrent therapy. The overall response rate was 86.4% (51/59). OS ranged from 0.4 to 36.7 months (median 6.5 months), and 1-year-survival rate was 21.3%. Treatment-related adverse events mainly included acute meningitis, chronic-delayed encephalopathy, radiculitis, myelosuppression and mucositis. Twelve patients (20.3%) had grade III-V toxic reactions. We concluded that IC combined with concomitant IF-RT, with significant efficacy and acceptable toxicity, may be an optimal therapeutic option for treatment of LM from solid tumors with adverse prognostic factors. LM, in which cancer cells spread to membranes enveloping the brain and spinal cord, is a devastating complication of solid cancers. Existing LM therapies center on IC. In this prospective

    This study evaluates the prognostic value of MAGE-A3 expression in 28 diffuse large B-cell lymphoma (DLBCL) patients. A significant association was observed between MAGE-A3 expressions, assessed by quantitative real-time RT-polymerase chain reaction (PCR), with advanced stages of disease (P < 0.05). Elevated serum lactate dehydrogenase (LDH) levels and International Prognostic Index (IPI) score were significantly higher in MAGE-A3-positive patients (P = 0.025 and P = 0.004, respectively). Expression of MAGE-A3 was associated with poor response to treatment and a significantly shorter overall survival (P < 0.001). Our data address new information in the association of MAGE-A3 expression and poor prognosis in DLBCL patients. PMID:22183072

    Infiltrating astrocytomas and oligoastrocytomas of low to anaplastic grade (WHO grades II and III), in spite of being associated with a wide range of clinical outcomes, can be difficult to subclassify and grade by the current histopathologic criteria. Unlike oligodendrogliomas and anaplastic oligodendrogliomas that can be identified by the 1p/19q codeletion and the more malignant glioblastomas (WHO grade IV astrocytomas) that can be diagnosed solely based on objective features on routine hematoxylin and eosin sections, no such objective criteria exist for the subclassification of grade II-III astrocytomas and oligoastrocytomas (A+OA II-III). In this study, we evaluated the prognostic and predictive value of the stem cell marker nestin in adult A+OA II-III (n=50) using immunohistochemistry and computer-assisted analysis on tissue microarrays. In addition, the correlation between nestin mRNA level and total survival was analyzed in the NCI Rembrandt database. The results showed that high nestin expression is a strong adverse prognostic factor for total survival (p=0.0004). The strength of the correlation was comparable to but independent of the isocitrate dehydrogenase 1/2 (IDH 1/2) mutation status. Histopathological grading and subclassification did not correlate significantly with outcome, although the interpretation of this finding is limited by the fact that grade III tumors were treated more aggressively than grade II tumors. These results suggest that nestin level and IDH 1/2 mutation status are strong prognostic features in A+OA II-III and possibly more helpful for treatment planning than routine histopathological variables such as oligodendroglial component (astrocytoma vs. oligoastrocytoma) and WHO grade (grade II vs. III).

    Purpose: Vaults are multi-subunit structures that may be involved in nucleo-cytoplasmic transport, with the major vault protein (MVP or lung resistance-related protein [LRP]) being the main component. The MVP gene is located on chromosome 16 close to the multidrug resistance-associated protein and protein kinase c-{beta} genes. The role of MVP in cancer drug resistance has been demonstrated in various cell lines as well as in ovarian carcinomas and acute myeloid leukemia, but nothing is known about its possible role in radiation resistance. Our aim was to examine this in head-and-neck squamous cell carcinoma (HNSCC). Methods and Materials: Archived biopsy material was obtained for 78 patients with squamous cell carcinoma of the oropharynx who received primary radiotherapy with curative intent. Immunohistochemistry was used to detect MVP expression. Locoregional failure and cancer-specific survival were estimated using cumulative incidence and Cox multivariate analyses. Results: In a univariate and multivariate analysis, MVP expression was strongly associated with both locoregional failure and cancer-specific survival. After adjustment for disease site, stage, grade, anemia, smoking, alcohol, gender, and age, the estimated hazard ratio for high MVP (2/3) compared with low (0/1) was 4.98 (95% confidence interval, 2.17-11.42; p 0.0002) for locoregional failure and 4.28 (95% confidence interval, 1.85-9.95; p = 0.001) for cancer-specific mortality. Conclusion: These data are the first to show that MVP may be a useful prognostic marker associated with radiotherapy resistance in a subgroup of patients with HNSCC.

    Purpose: Management of locally advanced rectal cancer (RC) consists of neoadjuvant chemoradiotherapy (CRT) with fluoropyrimidines, followed by total mesorectal excision. We sought to evaluate the expression of selected genes, some of which were derived from a previous undirected SAGE (serial analysis of gene expression)-based approach, before and after CRT, to identify mechanisms of resistance. Methods: This retrospective cohort study included 129 consecutive patients. Quantitative polymerase chain reaction of 53 candidate genes was performed on the biopsy specimen before treatment and on the surgical specimen after CRT. A paired-samples t test was performed to determine genes that were significantly changed after CRT. The result was correlated with patients' disease-free survival. Results: Twenty-two genes were significantly upregulated, and two were significantly downregulated. Several of the upregulated genes have roles in cell cycle control; these include CCNB1IP1, RCC1, EEF2, CDKN1, TFF3, and BCL2. The upregulation of TFF3 was associated with worse disease-free survival on multivariate analyses (hazard ratio, 2.64; P=.027). Patients whose surgical specimens immunohistochemically showed secretion of TFF3 into the lumen of the tumoral microglands had a higher risk of relapse (hazard ratio, 2.51; P=.014). In vitro experiments showed that DLD-1 cells stably transfected with TFF3 were significantly less sensitive to 5-fluorouracil and showed upregulation of genes involved in the transcriptional machinery and in resistance to apoptosis. Conclusion: Upregulation of TFF3 after CRT for RC is associated with a higher risk of relapse. The physiological role of TFF3 in restoring the mucosa during CRT could be interfering with treatment efficacy. Our results could reveal not only a novel RC prognostic marker but also a therapeutic target.

  9. Prognostic factors in ovarian cancer.

    There is obvious merit in being able to accurately predict outcome and tailor treatment according to individual risk and potential for benefit. Epithelial ovarian cancers are characterized by a broad spectrum of biological behavior ranging from tumors that have an excellent prognosis and high likelihood of cure to those that progress rapidly and have a very poor prognosis. This wide clinical spectrum is partly reflected by a number of clinicopathological prognostic variables which include International Federation of Gynecology and Obstetrics stage, histologic subtype and grade, volume of residual tumor remaining after surgical resection, performance status, and age. There has been increasing interest by many groups to incorporate the independent prognostic variables into multivariate models that could better predict outcome. This approach does appear to allow the identification of different prognostic subsets and requires confirmation in prospective studies. There has been, and there continues to be a lot of effort in identifying new prognostic factors that have a biologic rationale and these will be discussed. Most of these new prognostic factors have not been subjected to rigorous testing and this will be clearly necessary before they find clinical application. This is an area that is rapidly evolving with the increased understanding of the molecular basis for ovarian carcinogenesis and progression coupled with technological advances such as DNA arrays and automated polymerase chain reaction. We are at the threshold of developing a new and more objective as well as rational approach to predict prognosis and response to therapy.

    In the nineteenth century the main goal of medicine was predictive: diagnose the disease and achieve a satisfying prognosis of the patient's chances. Today the effort has shifted to cure the disease. Since the twentieth century, the word prognosis has also been used in nonmedical contexts, for example in corporate finance or elections. The most accurate form of prognosis is achieved statistically. Based on different prognostic factors it should be possible to tell patients how they are expected to do after prostate cancer has been diagnosed and how different treatments may change this outcome. A prognosis is a prediction. The word prognosis comes from the Greek word (see text) and means foreknowing. In the nineteenth century this was the main goal of medicine: diagnose the disease and achieve a satisfying prognosis of the patient's chances. Today the effort has shifted towards seeking a cure. Prognostic factors in (prostate) cancer are defined as "variables that can account for some of the heterogeneity associated with the expected course and outcome of a disease". Bailey defined prognosis as "a reasoned forecast concerning the course, pattern, progression, duration, and end of the disease. Prognostic factors are not only essential to understand the natural history and the course of the disease, but also to predict possible different outcomes of different treatments or perhaps no treatment at all. This is extremely important in a disease like prostate cancer where there is clear evidence that a substantial number of cases discovered by prostate-specific antigen (PSA) testing are unlikely ever to become clinically significant, not to mention mortal. Furthermore, prognostic factors are of paramount importance for correct interpretation of clinical trials and for the construction of future trials. Finally, according to WHO national screening committee criteria for implementing a national screening programme, widely accepted prognostic factors must be defined before

    Analyses of prognostic factors have allowed the design of staging systems in different haematological disorders. In a series of 220 patients with multiple myeloma, univariate analysis showed that nine parameters had a significant adverse effect on survival; poor performance status (Karnowsky scaling system less than 70%), infections before diagnosis, renal impairment (assessed either by creatinine clearance greater than 2 mg dl-1 or urea greater than 40 mg dl-1), serum calcium (greater than 10 mg dl-1), severe anaemia (less than 8.5 g dl-1), the presence of Bence-Jones proteinuria, failure to achieve complete remission, more than 40% plasma cells in bone marrow and a low paraprotein index (monoclonal component/% plasma cells: P less than 0.09). In addition, this index correlated significantly with all the other prognostic factors except performance status. The best combination of disease characteristics selected by means of the Cox regression proportional hazards method were performance status and creatinine levels. Additionally, by factor analysis of principal components we obtained a regression equation that included creatinine levels, haemoglobin, performance status and paraprotein index. Using this it was possible to separate the series of patients into three risk categories: A (65 patients), B (69 patients) and C (65 patients) with a median survival of 41, 24 and 12 months, respectively. The model provided similar results to those of the British Medical Research Council, whereas the staging systems proposed by Durie and Salmon, Merlin et al. and Carbone et al. had a lower discriminant value in our series.

    The aim of this study was to identify the prognostic factors related to the survival of patients with sarcomas of the jaw treated in the Dr. Eduardo Caceres Graziani National Institute for Neoplastic Diseases, Lima, Peru. Age, gender, delay in consultation, diagnostic delay, therapeutic delay, tumor size, tumor location, facial asymmetry, pain, treatment type, and histopathological diagnosis were all evaluated as possible prognostic factors that would influence survival in those with jaw sarcomas. In the analysis, the following was used: mortality tables, Kaplan-Meier's product-limit method, log-rank, and Breslow and Tarone-Ware tests; for the prognostic factors, Cox's Regression Model was used. The overall survival rate, with the patient being free from disease at two years, was 55%, and that at five years was 45%. In the independent analysis of the prognostic factors, four variables were statistically significant in influencing survival: gender (p = 0.043), histopathologic diagnosis (p = 0.019), tumor location (p = 0.019), and treatment type (p = 0.030). According to Cox's Regression Model for the multivariate analysis, statistically significant prognostic factors were: gender (p = 0.086), tumor location (p = 0.020), and treatment type (p = 0.092). Thus, the variables of gender, tumor location, and treatment type were determined to be predictive factors for prognosis of survival.

    Classical antineoplastic therapy is encumbered by extensively studied adverse reactions, most often of systemic nature. The emergence of new generations of anticancer treatments, including epidermal growth factor receptor inhibitors, besides improving the response to treatment and the survival rate, is accompanied by the occurrence of new specific side effects, incompletely studied. These side effects are most often cutaneous (hand foot syndrome, acneiform reactions), and in some cases are extremely severe, requiring dose reduction or drug discontinuation. The prevention of the cutaneous adverse effects and their treatment require a close collaboration between the oncologist and the dermatologist. The occurrence of some of these skin adverse effects may be a favorable prognostic factor for the response to the cancer treatment and the overall survival.

    Introduction: Data regarding prognostic factors of post-discharge mortality and adverse renal function outcome in acute kidney injury (AKI) hospital survivors are scarce and controversial. Objectives: We aimed to identify predictors of post-discharge mortality and adverse renal function outcome in AKI hospital survivors. Patients and Methods: The study group consisted of 84 AKI hospital survivors admitted to the tertiary medical center during 2-year period. Baseline clinical parameters, with renal outcome 3 months after discharge and 6-month mortality were evaluated. According survival and renal function outcome, patients were divided into two groups. Results: Patients who did not recover renal function were statistically significantly older (P < 0.007) with higher Charlson comorbidity index (CCI) score (P < 0.000) and more likely to have anuria and oliguria (P = 0.008) compared to those with recovery. Deceased AKI patients were statistically significantly older (P < 0.000), with higher CCI score (P < 0.000), greater prevalence of sepsis (P =0.004), higher levels of C-reactive protein (CRP) (P < 0.017) and ferritin (P < 0.051) and lower concentrations of albumin (P<0.01) compared to survivors. By multivariate analysis, independent predictors of adverse renal outcome were female gender (P =0.033), increasing CCI (P =0.000), presence of pre-existing chronic kidney disease (P =0.000) and diabetes mellitus (P =0.019) as well as acute decompensated heart failure (ADHF) (P =0.032), while protective factor for renal function outcome was higher urine output (P =0.009). Independent predictors of post-discharge mortality were female gender (P =0.04), higher CCI score (P =0.001) and sepsis (P =0.034). Conclusion: Female AKI hospital survivors with increasing burden of comorbidities, diagnosis of sepsis and ADHF seem to be at high-risk for poor post-discharge outcome. PMID:27471736

    Decision about the administration of adjuvant therapy for early breast cancer depends on the evaluation of prognostic factors. Lymph node status, tumor size and grade of differentiation are classical variables in this regard, and can be complemented by hormonal receptor status and HER2 expression. These factors can be combined into prognostic indexes to better estimate the risk of relapse or death. Other factors are less important. Gene profiles have emerged in recent years to identify low-risk patients who can forgo adjuvant chemotherapy. A number of profiles are available and can be used in selected cases. In the future, gene profiling will be used to select patients for treatment with new targeted therapies.

    Previous studies have reported an association between sun exposure and the increased survival of patients with cutaneous melanoma (CM). The present study analyzed the association between ultraviolet (UV) light exposure and various prognostic factors in the Italian Clinical National Melanoma Registry. Clinical and sociodemographic features were collected, as well as information concerning sunbed exposure and holidays with sun exposure. Analyses were performed to investigate the association between exposure to UV and melanoma prognostic factors. Between December 2010 and December 2013, information was obtained on 2,738 melanoma patients from 38 geographically representative Italian sites. A total of 49% of the patients were >55 years old, 51% were men, 50% lived in the north of Italy and 57% possessed a high level of education (at least high school). A total of 8 patients had a family history of melanoma and 56% had a fair phenotype (Fitzpatrick skin type I or II). Of the total patients, 29% had been diagnosed with melanoma by a dermatologist; 29% of patients presented with a very thick melanoma (Breslow thickness, >2 mm) and 25% with an ulcerated melanoma. In total, 1% of patients had distant metastases and 13% exhibited lymph node involvement. Holidays with sun exposure 5 years prior to CM diagnosis were significantly associated with positive prognostic factors, including lower Breslow thickness (P<0.001) and absence of ulceration (P=0.009), following multiple adjustments for factors such as sociodemographic status, speciality of doctor performing the diagnosis and season of diagnosis. Sunbed exposure and sun exposure during peak hours of sunlight were not significantly associated with Breslow thickness and ulceration. Holidays with sun exposure were associated with favorable CM prognostic factors, whereas no association was identified between sunbed use and sun exposure during peak hours of sunlight with favorable CM prognostic factors. However, the results of the

    Purpose: To review the existing literature regarding the characteristics, prognostic factors, treatment, and survival of patients with medulloblastoma, who develop extraneural metastasis (ENM). Methods and Materials: A PubMed search of English language articles from 1961 to 2007 was performed, yielding 47 articles reporting on 119 patients. Factors analyzed included age, time interval to development of ENM, ENM location, central nervous system (CNS) involvement, treatment, and outcome. Results: Sites of ENM included bone in 84% of patients, bone marrow in 27% of patients, lymph nodes in 15% of patients, lung in 6% of patients, and liver in 6% of patients. Median survival was 8 months after diagnosis of ENM. The 1-, 2-, and 5-year overall survival (OS) rates after diagnosis of ENM were 41.9%, 31.0%, and 26.0%, respectively. The 1-, 2-, and 5-year progression-free survival (PFS) rates after diagnosis of ENM were 34.5%, 23.2%, and 13.4%, respectively. For patients without CNS involvement at the time of ENM diagnosis, the 1-, 2-, and 5-year OS rates for those treated with and without radiotherapy (RT) were 82.4%, 64.8%, and 64.8% vs. 51.0%, 36.6%, and 30.5%, respectively (p = 0.03, log-rank test). RT did not significantly improve OS or PFS rates for those with CNS involvement. Concurrent CNS involvement, ENM in the lung or liver, a time interval of <18 months to development of ENM, and a patient age of <16 years at ENM diagnosis were found to be negative prognostic factors for both OS and PFS. Conclusions: Several prognostic factors were identified for patients with ENM from medulloblastoma. Patients without concurrent CNS involvement, who received RT after ENM diagnosis had an OS and PFS benefit compared to those who did not receive RT.

    Background Organophosphates and carbamates are insecticides that are associated with high human mortality. The purpose of this study is to investigate the prognostic factors affecting survival in patients with cholinesterase inhibitor (CI) poisoning. Material/Methods This study included 92 patients with CI poisoning in the period from January 2005 to August 2013. We divided these patients into 2 groups (survivors vs. non-survivors), compared their clinical characteristics, and analyzed the predictors of survival. Results The mean age of the included patients was 56 years (range, 16–88). The patients included 57 (62%) men and 35 (38%) women. When we compared clinical characteristics between the survivor group (n=81, 88%) and non-survivor group (n=11, 12%), there were no differences in renal function, pancreatic enzymes, or serum cholinesterase level, except for serum bicarbonate level and APACHE II score. The serum bicarbonate level was lower in non-survivors than in survivors (12.45±2.84 vs. 18.36±4.73, P<0.01). The serum APACHE II score was higher in non-survivors than in survivors (24.36±5.22 vs. 12.07±6.67, P<0.01). The development of pneumonia during hospitalization was higher in non-survivors than in survivors (n=9, 82% vs. n=31, 38%, P<0.01). In multiple logistic regression analysis, serum bicarbonate concentration, APACHE II score, and pneumonia during hospitalization were the important prognostic factors in patients with CI poisoning. Conclusions Serum bicarbonate and APACHE II score are useful prognostic factors in patients with CI poisoning. Furthermore, pneumonia during hospitalization was also important in predicting prognosis in patients with CI poisoning. Therefore, prevention and active treatment of pneumonia is important in the management of patients with CI poisoning. PMID:26411989

    Background: Sudden sensorineural hearing loss (SSNHL) is still a complex and challenging process which requires clinical evidence regarding its etiology, treatment and prognostic factors. Therefore, determination of prognostic factors might aid in the selection of proper treatment modality. Aims: The aim of this study is to analyze whether there is correlation between SSNHL outcomes and (1) systemic steroid therapy, (2) time gap between onset of symptoms and initiation of therapy and (3) audiological pattern of hearing loss. Study Design: Retrospective chart review. Methods: Patients diagnosed at our clinic with SSNHL between May 2005 and December 2011 were reviewed. A detailed history of demographic features, side of hearing loss, previous SSNHL and/or ear surgery, recent upper respiratory tract infection, season of admission, duration of symptoms before admission and the presence of co-morbid diseases was obtained. Radiological and audiological evaluations were recorded and treatment protocol was assessed to determine whether systemic steroids were administered or not. Treatment started ≤5 days was regarded as “early” and >5 days as “delayed”. Initial audiological configurations were grouped as “upward sloping”, “downward sloping”, “flat” and “profound” hearing loss. Significant recovery was defined as thresholds improved to the same level with the unaffected ear or improved ≥30 dB on average. Slight recovery was hearing improvement between 10–30dB on average. Hearing recovery less than 10 dB was accepted as unchanged. Results: Among the 181 patients who met the inclusion criteria, systemic steroid was administered to 122 patients (67.4%), whereas 59 (32.6%) patients did not have steroids. It was found that steroid administration did not have any statistically significant effect in either recovered or unchanged hearing groups. Early treatment was achieved in 105 patients (58%) and 76 patients (42%) had delayed treatment. Recovery

    Purpose: To analyze the role of radiation therapy (RT) on the adverse prognostic influence of cyclooxygenase-2 (COX-2) expression on Reed-Sternberg (RS) cells, in the setting of early Hodgkin lymphoma (HL) treated with ABVD (adriamycin, vinblastine, bleomycin, dacarbazine). Methods and Materials: In the present study we retrospectively investigated the prognostic value of COX-2 expression in a large (n=143), uniformly treated early HL population from the Spanish Network of HL using tissue microarrays. Univariate and multivariate analyses were done, including the most recognized clinical variables and the potential role of administration of adjuvant RT. Results: Median age was 31 years; the expression of COX-2 defined a subgroup with significantly worse prognosis. Considering COX-2{sup +} patients, those who received RT had significantly better 5-year progression-free survival (PFS) (80% vs 54% if no RT; P=.008). In contrast, COX-2{sup −} patients only had a modest, nonsignificant benefit from RT in terms of 5-year PFS (90% vs 79%; P=.13). When we compared the outcome of patients receiving RT considering the expression of COX-2 on RS cells, we found a nonsignificant 10% difference in terms of PFS between COX-2{sup +} and COX-2{sup −} patients (P=.09), whereas the difference between the 2 groups was important (25%) in patients not receiving RT (P=.04). Conclusions: Cyclooxygenase-2 RS cell expression is an adverse independent prognostic factor in early HL. Radiation therapy overcomes the worse prognosis associated with COX-2 expression on RS cells, acting in a chemotherapy-independent way. Cyclooxygenase-2 RS cell expression may be useful for determining patient candidates with early HL to receive consolidation with RT.

    The authors conducted a multivariate analysis of the prognostic factors in 96 patients with early glottic cancer treated by radiation therapy. Of these, 73 had T/sub 1/ and 23 had T/sub 2/ tumor. The primary tumor was controlled in 82% of T/sub 1/ amd 74% for T/sub 2/. Carcinoma of the anterior commissure associated with bilateral vocal cord involvement, subglottic tumor extension, persistent or recurrent laryngeal edema, and impaired cord mobility was found to adversely influence the prognosis. The data suggest that irradiation is the treatment of choice for glottic cancer limited to the vocal cords or with minimal extension to the anterior commissure or gupraglottic larynx.

    Purpose. In an attempt to identify clinical and histopathological factors of prognostic importance in chondrosarcomas, 115 cases of malignant and borderline chondromatous tumours were reviewed. Patients/methods. Histopathological features tested for prognostic information as well as reproducibility included cellularity, nuclear pleomorphism, multinucleated cells, mitotic activity and grade. Eleven patients had a biopsy only, and a short survival (median 2.0 years); these were excluded from further analysis. The remaining 104 patients who had received intended curative treatment had a median survival of 14.7 years. Results. In univariate analysis, tumour size, extra-compartmental growth, surgical margin and sex were significantly correlated to recurrence-free survival (RFS); sex was marginally significant while age, site and pathological parameters were not significant. Overall survival (OAS) was likewise found to be independent of pathological features as well as site, size and surgical margin; but age, sex and extra-compartmental growth were statistically significant. However, when the same parameters were entered into a stepwise Cox (multivariate) analysis, only surgical margin, cellularity and pleomorphism were significantly related to RFS; margin, grade, pleomorphism and age to OAS. Overall inter-observer agreement on grade was relatively low: 0.54, with a Kappa value of 0.32. It was not better for the other histological parameters, with the exception of the mitotic count. However, acceptable values were achieved when the material was divided into low-grade (grade I and below) vs high-grade (grade II and III) lesions: overall agreement 0.79, Kappa 0.56. Discussion. Although the grading of chondrosarcomas is in need of improvement, its replacement by semiquantitative evaluation of individual histopathological parameters as performed in this study offers no advantage. Among the clinical parameters, only the adequacy of the surgical treatment and the patient's age

    In a prospective study, the prognostic value of clinical characteristics in 157 consecutive patients with spontaneous supratentorial intracerebral haemorrhage were examined by means of multivariate analysis. Two days after the event 37 (24%) patients had died. Factors independently contributing to the prediction of two day mortality were pineal gland displacement on CT of 3 mm or more (p less than 0.001), blood glucose level on admission of 8.0 mmol/l or more (p = 0.01), eye and motor score on the Glasgow Coma Scale of eight out of 10 or less (p = 0.022) and haematoma volume of 40 cm3 or more (p = 0.037). Between the third day and one year after the event another 46 of the 120 two day survivors had died; the independent prognostic indicators for death during that period were: age 70 years or more (p less than 0.001) and severe handicap (Rankin grade five) on the third day (p less than 0.001). Functional independence (Rankin grade two or less) at one year was most common not only with the converse features of age less than 70 years (p less than 0.01) and Rankin grade four or less on the third day (p = 0.002), but also with an eye and motor score on the Glasgow Coma Scale of nine or 10 on the third day (p less than 0.001). The 120 patients with intracerebral haemorrhage who were still alive two days after the event were matched with 120 patients with cerebral infarction, according to age, level of consciousness on the third day after stroke (Glasgow Coma Scale) and handicap (Rankin grade). Survival and handicap after one year did not differ between these two groups. The conclusion drawn is that it is not the cause (intracerebral haemorrhage or cerebral infarction) but the extent of the brain lesion that determines the outcome in patients who survive the first two days.

    Clinical and pathologic data from 51 patients with primary sarcomas of the gastrointestinal tract treated from 1951 through 1984 were reviewed to determine clinical presentation, histologic features, treatment, and prognostic factors. The most common signs and symptoms were abdominal pain (62%), gastrointestinal bleeding (40%), and/or abdominal mass (38%). The primary site was stomach in 50%, small bowel in 30%, colorectum in 15%, and esophagus in 5%. Virtually all the sarcomas were leiomyosarcomas. Distribution was uniform among the three histologic grades; although 88% of Grade 1 tumors could be completely excised, only 35% of Grade 3 tumors could be completely resected. The 5-year survival rate was 75% for Grade 1 tumors, 16% for Grade 2 tumors, and 28% for Grade 3 tumors (p = 0.0013, Grade 1 vs. 2 and 3). Thirty of the 51 patients (59%) had curative resection with an operative morbidity rate of 24% and an operative mortality rate of 12%; at 5 years the disease-free survival rate was 58% and the overall survival rate was 63% (48% at 10 years). Eleven patients (42%) had recurrent disease develop at a median interval of 2 years after complete tumor excision. Twenty-one patients (41%) had partial excision or biopsy only of their tumors with an operative morbidity rate of 28%, operative mortality rate of 8%, and median survival of only 9 months. Overall, patients whose tumors were confined to the site of origin had a 58% 5-year survival rate compared with 20% for those whose tumors had invaded adjacent organs (p less than 0.05). If the tumor was less than 10 cm in size, the 5-year survival rate was 78%, significantly better than the 38% for tumors greater than 10 cm (p = 0.03). These data suggest that histologic grade, local invasiveness, size, and extent of resection are the most important prognostic factors for patients with primary gastrointestinal sarcomas. Patients who have resection of all gross tumor, especially if it is well differentiated and localized

    Knowledge discovery, statistical learning, and more specifically an understanding of the system evolution in time when it undergoes undesirable fault conditions, are critical for an adequate implementation of successful prognostic systems. Prognosis may be understood as the generation of long-term predictions describing the evolution in time of a particular signal of interest or fault indicator, with the purpose of estimating the remaining useful life (RUL) of a failing component/subsystem. Predictions are made using a thorough understanding of the underlying processes and factor in the anticipated future usage.

    In prostate cancer, whatever the stage of the disease, the selection of a treatment strategy is based on prognostic factors. Clinical stage, serum PSA concentration and Gleason score are among the most recognised factors. A combination of these three parameters leads to a score used to define prognostic groups that are routinely used in daily practice. More recently, predictive statistical models have been developed that were associated with nomograms. The objective of nomograms is, for a given patient, to calculate his probability to develop disease extension or relapse based on clinical, biological, histological and therapeutic (radiotherapy, hormonotherapy) data. Such nomograms are not all validated and their application in daily practice is more difficult than that of classical prognostic classifications. Nowadays, the progress and accessibility to novel technologies applied to biology will make possible in the near future the assessment of new prognostic profiles based on genetic and/or proteomic tumour characteristics.

    Background Inflammation is an important factor in the pathogenesis of calcific aortic stenosis (AS). We aimed to evaluate the association between an inflammatory marker, neutrophil-to-lymphocyte ratio (NLR) and major adverse cardiovascular events (MACE) in patients with severe calcific AS. Methods A total of 336 patients with isolated severe calcific AS newly diagnosed between 2010 and 2015 were enrolled in this study. Using Cox proportional hazards (PH) regression models, we investigated the prognostic value of NLR adjusted for baseline covariates including logistic European System for Cardiac Operative Risk Evaluation score (EuroSCORE-I) and undergoing aortic valve replacement (AVR). We also evaluated the clinical relevance of NLR risk groups (divided into low, intermediate, high risk) as categorized by NLR cutoff values. MACE was defined as a composite of all-cause mortality, cardiac death and non-fatal myocardial infarction during the follow-up period. Results The inflammatory marker NLR was an independent prognostic factor most significantly associated with MACE [hazard ratio (HR), 1.06; 95% confidence interval (CI), 1.04–1.09; p-value <0.001]. The goodness-of-fit and discriminability of the model including EuroSCORE-I and AVR (loglikelihood difference, 15.49; p-value <0.001; c-index difference, 0.035; p-value = 0.03) were significantly improved when NLR was incorporated into the model. The estimated Kaplan-Meier survival rates at 5 years for the NLR risk groups were 84.6% for the low risk group (NLR ≤ 2), 67.7% for the intermediate risk group (2 < NLR ≤ 9), and 42.6% for the high risk group (NLR > 9), respectively. Conclusion The findings of the present study demonstrate the potential utility of NLR in risk stratification of patients with severe calcific AS. PMID:27548384

    Diagnostic cytogenetic abnormalities are considered important prognostic factors in patients with acute myeloid leukaemia (AML). However, the prognostic assessments have mainly been derived from patients with AML aged <60 years. Two recent studies of AML patients of 60 years and older proposed prognostic classifications with distinct discrepancies. To further study the prognostic value of cytogenetic abnormalities in this patient population, we have evaluated cytogenetic abnormalities in a series of 293 untreated patients with AML aged 60 years and older, included in a randomised phase 3 trial, also in relation to patient characteristics and clinical outcome. The most frequently observed cytogenetic abnormality was trisomy 8 (+8), in 31 (11%) patients. Abnormalities, such as -5, 5q-, abn(17p) and abn(17q), were almost exclusively present in complex karyotypes. A relatively favourable outcome was only observed in five patients with core-binding factor abnormalities t(8;21) and inv(16)/del(16)/t(16;16). However, most of the other evaluated cytogenetic abnormalities, such as 5q-, -7, +8, abn(17p), abn(17q), and complex aberrations expressed a more adverse prognosis when compared with patients with AML aged 60 years and older with a normal karyotype. Large studies to confirm the prognosis of individual cytogenetic aberrations are warranted.

    Idiopathic CD4+ lymphocytopenia (ICL) is a rare non–HIV-related syndrome with unclear natural history and prognosis. This prospective natural history cohort study describes the clinical course, CD4 T lymphocyte kinetics, outcome, and prognostic factors of ICL. Thirty-nine patients (17 men, 22 women) 25 to 85 years old with ICL were evaluated between 1992 and 2006, and 36 were followed for a median of 49.5 months. Cryptococcal and nontuberculous mycobacterial infections were the major presenting opportunistic infections. Seven patients presented with no infection. In 32, CD4 T-cell counts remained less than 300/mm3 throughout the study period and in 7 normalized after an average of 31 months. Overall, 15 (41.6%) developed an opportunistic infection in follow-up, 5 (13.8%) of which were “AIDS-defining clinical conditions,” and 4 (11.1%) developed autoimmune diseases. Seven patients died, 4 from ICL-related opportunistic infections, within 42 months after diagnosis. Immunologic analyses revealed increased activation and turnover in CD4 but not CD8 T lymphocytes. CD8 T lymphocytopenia (< 180/mm3) and the degree of CD4 T cell activation (measured by HLA-DR expression) at presentation were associated with adverse outcome (opportunistic infection-related death; P = .003 and .02, respectively).

    An ependymoma is an uncommon glial tumor, which arises from different parts of the neuroaxis. Considerable variation in presentation and survival in tumors in different locations after an optimum treatment indicates inherent molecular and genetic differences in tumorigenesis between them. A number of genetic aberrations have been identified to distinctly characterize different subgroups of ependymomas that include a posterior fossa tumor, a supratentorial tumor, and a pediatric tumor. These different groups have substantial genetic alterations, and also distinct demography, clinical characteristics, and prognosis. This article is intended to review the diverse molecular and genetic aberrations that may be helpful in prognostication and prediction of survival in patients suffering from an ependymoma.

    The optimal adjuvant radiotherapy for surgically treated endometrial cancer has not yet been defined. We report on 389 patients treated between 1970 and 1985 with adjuvant radiotherapy. The treatment was tailored to the known prognostic factors: myometrial invasion and grade of differentiation of the tumor. Ten-year overall survival was 67%, 10-year relapse-free survival 77%; 23% relapse, of which 21% distant and 6% locoregional relapse. In a multivariate analysis, stage (pT), grade, and myometrial invasion were prognostic factors. The number of locoregional failures was very small (n = 23). This small number, the fact that radiation treatment was tailored to prognostic factors, and the absence of a nontreated control group precluded an analysis of the effect of the adjuvant irradiation. Large randomized studies with a control (no treatment) arm should be performed to determine the value of adjuvant radiotherapy. PMID:2303362

    Background: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT. Aims: We aimed to define the prognostic and predictive factors associated with treatment options in ovarian (OCS) and uterine carcinosarcoma (UCS). Study Design: Retrospective cross-sectional study Methods: We retrospectively reviewed the medical records of patients with ovarian and uterine carcinosarcoma from 2000 to 2013, and 127 women were included in this study (24 ovarian and 103 uterine). Patients admitted to seventeen oncology centres in Turkey between 2000 and December 2013 with a histologically proven diagnosis of uterine carcinosarcoma with FIGO 2009 stage I–III and patients with sufficient data obtained from well-kept medical records were included in this study. Stage IV tumours were excluded. The patient records were retrospectively reviewed. Data from 104 patients were evaluated for this study. Results: Age (≥70 years) was a poor prognostic factor for UCS (p=0.036). Pelvic±para aortic lymph node dissection did not affect overall survival (OS) (p=0.35). Macroscopic residual disease was related with OS (p<0.01). The median OS was significantly longer in stage I–II patients than stage III patients (p=0.03). Adjuvant treatment improved OS (p=0.013). Adjuvant radiotherapy tended to increase the median OS (p=0.075). However, this tendency was observed in UCS (p=0.08) rather than OCS (p=0.6).Adjuvant chemotherapy had no effect on OS (p=0.15).Adjuvant radiotherapy significantly prolonged the median OS in patients with endometrioid component (p=0.034).

    Approximately 20% of patients with acute pancreatitis develop a severe disease associated with complications and high risk of mortality. The purpose of this study is to review pathogenesis and prognostic factors of severe acute pancreatitis (SAP). An extensive medline search was undertaken with focusing on pathogenesis, complications and prognostic evaluation of SAP. Cytokines and other inflammatory markers play a major role in the pathogenesis and course of SAP and can be used as prognostic markers in its early phase. Other markers such as simple prognostic scores have been found to be as effective as multifactorial scoring systems (MFSS) at 48 h with the advantage of simplicity, efficacy, low cost, accuracy and early prediction of SAP. Recently, several laboratory markers including hematocrit, blood urea nitrogen (BUN), creatinine, matrix metalloproteinase-9 (MMP-9) and serum amyloid A (SAA) have been used as early predictors of severity within the first 24 h. The last few years have witnessed a tremendous progress in understanding the pathogenesis and predicting the outcome of SAP. In this review we classified the prognostic markers into predictors of severity, pancreatic necrosis (PN), infected PN (IPN) and mortality. PMID:18205255

    To establish whether a combination of morphologic and immunophenotypic criteria could be developed to more precisely define Waldenström macroglobulinemia (WM) and prognostic factors, we retrospectively assessed the clinical and laboratory features of 111 cases of WM. Bone marrow infiltration by small lymphocytes was documented in each case; and diffuse, interstitial, nodular, and paratrabecular patterns of infiltration were documented in 58%, 32%, 6%, and 4% of cases, respectively. Ninety percent were characterized by a surface immunoglobulin-positive, CD19+CD20+CD5-CD10-CD23- immunophenotype. The median overall survival from diagnosis was 60 months; univariate analysis revealed the following adverse prognostic factors: older than 60 years, performance status more than 1, platelet count less than 100 x 10(3)/microL (< 100 x 10(9)/L), pancytopenia, and diffuse bone marrow infiltration. Associated median survival was 40, 38, 46, 28, and 59 months, respectively. Multivariate analysis revealed age, performance status, and platelet count as prognostically significant, but stratification of patients according to the International Prognostic Index had limited value. We suggest defining WM by the following criteria: IgM monoclonal gammopathy; bone marrow infiltration by small lymphocytes, plasmacytoid cells, and plasma cells in a diffuse, interstitial, or nodular pattern; and a surface immunoglobulin-positive, CD19+CD20+CD5-CD10-CD23- immunophenotype.

    Stratification of cardiovascular risk is of fundamental importance in white coat hypertension (WCH) to identify individuals in need of closer follow-up and perhaps antihypertensive drug treatment. In subjects representative of the general population of Monza (Italy), the risk of cardiovascular and all-cause mortality was assessed >16 years in stable and unstable WCH individuals, that is, those in whom ambulatory blood pressure (BP) normality was associated with a persistent or nonpersistent office BP elevation at 2 consecutive visits, respectively. Data were compared with those from an entirely normotensive group, that is, ambulatory and persistent office BP normality. Compared with the normotensive group, the risk of cardiovascular and all-cause death was not significantly different in unstable WCH, whereas in stable WCH the risk was increased also when data were adjusted for baseline confounders, including ambulatory BP (hazard ratio, 16; P=0.001 for cardiovascular death and 1.92; P=0.02 for all-cause death). At a multivariable analysis, office BP was among the factors independently predicting death, and results were superimposable with use of Monza population-derived and guidelines-derived cutoff values for ambulatory BP normality (125/79 and 130/80 mm Hg, respectively). Thus, only when office BP is persistently elevated does WCH reflect the existence of an abnormal long-term mortality risk. This means that in WCH office BP is prognostically relevant and that repeated collection of its values is clinically important to better define patient risk.

    There is considerable heterogeneity in the clinical outcome of patients with chronic lymphocytic leukemia (CLL). While some patients live for decades without any therapy, others die within years of diagnosis despite multiple treatments. To better counsel newly diagnosed CLL patients about their disease course, the Rai and Binet staging systems were developed four decades ago. A deeper understanding of the biologic and molecular aberrations contributing to the pathogenesis of CLL led to identification of novel prognostic markers such as immunoglobulin heavy-chain variable gene (IGHV) mutation status, leukemia-cell expression of CD38, ZAP-70, and CD49d, and cytogenetic abnormalities detected by fluorescent in situ hybridization (FISH). The advent of next-generation sequencing has provided unprecedented insights into the subclonal architecture of CLL and its impact on disease progression and survival. More recently, integrated prognostic scoring systems that incorporate clinical, biologic and genetic characteristics into a single risk score have been developed and appear to improve the accuracy of prognostication for individual patients. This review summarizes the state-of-the-art prognostic factors and will guide the practicing clinician in their care of patients with CLL. PMID:27040701

    Background The breast is a rare site of extranodal involvement of diffuse large B-cell lymphoma (DLBCL). We aimed to assess the clinical characteristics, prognostic factors, and treatment outcomes of breast DLBCL. Patients and methods We retrospectively analyzed 113 patients (from our institution and the literature) between 1973 and 2014. The primary end point was overall survival (OS). Kaplan–Meier OS curves were compared with the log-rank test. Cox regression analysis was applied to determine the prognostic factors for OS, progression-free survival (PFS), local control (LC), and cause-specific survival (CSS). Results A total of 113 patients were included in the study: 42 cases from our hospital and 71 cases from 12 publications. The median age at diagnosis was 58 years. With a median follow-up time of 39.2 months, the estimated 5-year OS, PFS, LC, and CSS were 71.4%, 58.8%, 75.6%, and 74.9%, respectively. In multivariate analysis, more than four cycles of chemotherapy, having localized cancer, lumpectomy with or without axillary lymph node (ALN) dissection, and low to low-to-intermediate International Prognostic Index were favorable factors for OS. For PFS, significant prognostic factors were rituximab use, B symptoms, and tumor size. As for the local group, lumpectomy with or without ALN dissection and more than four cycles of chemotherapy were favorable factors for OS. Tumor size >4 cm and nonuse of rituximab were adverse factors for PFS. Twenty-one patients (18.6%) developed local relapse and 33 (29.2%) developed systemic relapse. Eight patients had central nervous system relapse (7.3%). Conclusion Our results reveal that local and extended staging criteria can reflect the different prognosis and treatment outcomes of breast DLBCL. Rituximab use, lumpectomy, and more than four cycles of chemotherapy are recommended as a treatment regimen. However, further study is warranted to validate our data. PMID:27103833

    The recurrence of hepatocellular carcinoma, the sixth most common neoplasm and the third leading cause of cancer-related mortality worldwide, represents an important clinical problem, since it may occur after both surgical and medical treatment. The recurrence rate involves 2 phases: an early phase and a late phase. The early phase usually occurs within 2 years after resection; it is mainly related to local invasion and intrahepatic metastases and, therefore, to the intrinsic biology of the tumor. On the other hand, the late phase occurs more than 2 years after surgery and is mainly related to de novo tumor formation as a consequence of the carcinogenic cirrhotic environment. Since recent studies have reported that early and late recurrences may have different risk factors, it is clinically important to recognize these factors in the individual patient as soon as possible. The aim of this review was, therefore, to identify predicting factors for the recurrence of hepatocellular carcinoma, by means of invasive and non-invasive methods, according to the different therapeutic strategies available. In particular the role of emerging techniques (e.g., transient elastography) and biological features of hepatocellular carcinoma in predicting recurrence have been discussed. In particular, invasive methods were differentiated from non-invasive ones for research purposes, taking into consideration the emerging role of the genetic signature of hepatocellular carcinoma in order to better allocate treatment strategies and surveillance follow-up in patients with this type of tumor.

  7. Gallbladder carcinoma: Prognostic factors and therapeutic options

    The outcome of gallbladder carcinoma is poor, and the overall 5-year survival rate is less than 5%. In early-stage disease, a 5-year survival rate up to 75% can be achieved if stage-adjusted therapy is performed. There is wide geographic variability in the frequency of gallbladder carcinoma, which can only be explained by an interaction between genetic factors and their alteration. Gallstones and chronic cholecystitis are important risk factors in the formation of gallbladder malignancies. Factors such as chronic bacterial infection, primary sclerosing cholangitis, an anomalous junction of the pancreaticobiliary duct, and several types of gallbladder polyps are associated with a higher risk of gallbladder cancer. There is also an interesting correlation between risk factors and the histological type of cancer. However, despite theoretical risk factors, only a third of gallbladder carcinomas are recognized preoperatively. In most patients, the tumor is diagnosed by the pathologist after a routine cholecystectomy for a benign disease and is termed ‘‘incidental or occult gallbladder carcinoma’’ (IGBC). A cholecystectomy is performed frequently due to the minimal invasiveness of the laparoscopic technique. Therefore, the postoperative diagnosis of potentially curable early-stage disease is more frequent. A second radical re-resection to complete a radical cholecystectomy is required for several IGBCs. However, the literature and guidelines used in different countries differ regarding the radicality or T-stage criteria for performing a radical cholecystectomy. The NCCN guidelines and data from the German registry (GR), which records the largest number of incidental gallbladder carcinomas in Europe, indicate that carcinomas infiltrating the muscularis propria or beyond require radical surgery. According to GR data and current literature, a wedge resection with a combined dissection of the lymph nodes of the hepatoduodenal ligament is adequate for T1b and T2

    Introducción: frecuentemente debe tomarse una decisión terapéutica para el manejo del meningioma en el paciente geriátrico. El presente estudio analiza factores pronósticos, así como la escala Clinical- Radiological Grading Score (CRGS) como auxiliar para la decisión terapéutica. Métodos: se realizó un estudio retrospectivo entre 2009 y 2010. La población estudiada fue de 28 pacientes mayores de 65 años de edad. Se analizaron factores clínicos, imagenológicos e histopatológicos. Se utilizó la prueba chi cuadrada y la exacta de Fisher para variables cuantitativas y U de Mann-Whitney para variables cualitativas. Resultados: la mortalidad global a los 3, 6 y 12 meses de seguimiento fue del 7.14, 10.71 y 14.28 %, respectivamente. El análisis reveló que el estado funcional con la escala de Karnofsky (p = 0.02), la localización de la lesión (p = 0.002), el grado de malignidad histopatológico (p = 0.038) y una puntuación menor de 10 en la escala CRGS (p = 0.003) se asocian con un mal pronóstico. Conclusión: el manejo neuroquirúrgico del paciente geriátrico es una posibilidad terapéutica con un pronóstico favorable en pacientes con una puntuación igual o mayor de 10 y en aquellos con un adecuado estado funcional.

    The records of 65 patients with diagnoses of extensive intestinal ischaemia during the 10 years from December 1973 to January 1984 were retrieved from 18 hospitals in Ireland. There were 32 males and 33 females, ranging in age from 20 to 96 years (mean 69.8 years). Duration of symptoms ranged from 4 h to 8 days. Pain was the most common presenting feature. Gastrointestinal haemorrhage was apparent in 31%, hypotension in 28% and atrial fibrillation in 43%. Associated vascular disease was present in 43%. There were elevations of serum inorganic phosphate in 15%, leucoytosis in 65% and metabolic acidosis in 67%. The mean interval from hospital admission to operation in survivors was 14.5 h, whereas the mean delay in those who died was 44 h. The correct preoperative diagnosis was made in 23 (35%) and the aetiology of intestinal ischaemia was recorded as: thrombosis 25 (39%), embolism 12 (18%), adhesions/volvulus 4 (6%) and indeterminate in 24 (37%). Laparotomy was performed in 49: gangrenous bowel was resected in 29 and six had operations designed to revascularise the intestine. The remaining 14 patients either had laparotomy alone (12) or an inappropriate operation (2). In 46 patients (70.8%) who died, death was related to three factors: the mean age of survivors was 7 years less than that of patients who died, the interval to laparotomy was on average 30 h less, and the length of ischaemic bowel was on average 61% less.

    In 215 patients with operable breast cancer (T1-T3, N0-1, M0) and no other or previous cancer, presenting to a single breast unit, sufficient tumour was available for the prospective determination of four putative biochemical markers of prognosis: oestrogen receptor (ER) activity, cathepsin D (cath D), epidermal growth factor receptor (EGFR) activity and cyclic AMP-binding proteins (c-AMP-b). There were significant inter-relationships between ER and EGFR (r = -0.26), c-AMP-b and cath D (r = +0.32) and ER and c-AMP-b (r = +0.14). After follow-up (median 36.2 months), a total of 55 recurrences (18 locoregional only) and 35 deaths were recorded. By univariate analysis, up to 10 of 18 biochemical, clinical and histopathological variables of potential prognostic value were significantly related to disease-free interval or death, but by multivariate analysis only oestrogen receptor concentration and node status contributed significantly to risk of both distant recurrence/death; in addition, tumour size made a small contribution to the risk for a distant recurrence only. Only two parameters, tumour grade and ER concentration, were significantly related to risk of locoregional recurrence by univariate analysis, but by multivariate analysis, only tumour grade was important. It is concluded that tumour ER concentration, axillary nodal status and tumour grade remain as the most important prognostic factors in the early years after presentation of operable breast cancer, with a minor influence of tumour size. At this time, the prognostic significance of quantitative measurements of ER concentration, carefully controlled for the quality of both assay and tumour specimen, is probably greater than is generally appreciated. We have yet to identify other factors, which add significantly to the short-term prognostic value of these key features. PMID:8912547

    Background Estimating the future course of musculoskeletal pain is an important consideration in the primary care consultation for patients and healthcare professionals. Studies of prognostic indicators tend to have been viewed in relation to each site separately, however, an alternative view is that some prognostic indicators may be common across different sites of musculoskeletal pain. Aim To identify generic prognostic indicators for patients with musculoskeletal pain in primary care. Design of study Systematic review. Setting Observational cohort studies in primary care. Method MEDLINE, EMBASE, PsychINFO and CINAHL electronic databases were searched from inception to April 2006. Inclusion criteria were that the study was a primary care-based cohort, published in English and contained information on prognostic indicators for musculoskeletal conditions. Results Forty-five studies were included. Eleven factors, assessed at baseline, were found to be associated with poor outcome at follow up for at least two different regional pain complaints: higher pain severity at baseline, longer pain duration, multiple-site pain, previous pain episodes, anxiety and/or depression, higher somatic perceptions and/or distress, adverse coping strategies, low social support, older age, higher baseline disability, and greater movement restriction. Conclusion Despite substantial heterogeneity in the design and analysis of original studies, this review has identified potential generic prognostic indicators that may be useful when assessing any regional musculoskeletal pain complaint. However, Its unclear whether these indicators, used alone, or in combination, can correctly estimate the likely course of individual patients' problems. Further research is needed, particularly in peripheral joint pain and using assessment methods feasible for routine practice. PMID:17688762

    Background Hepatocellular carcinoma (HCC) is a common cancer worldwide as well as in Egypt with hepatitis C and B, alcohol and aflatoxins being the commonest risk factors. Aim The objective of this study was to assess the prognostic factors affecting overall survival (OS) of untreated HCC in Egypt. Methods This retrospective study was conducted at Tanta Cancer Center, Egypt where 288 HCC cases who received no specific therapy and were followed-up until death were identified. The impact of possible prognostic factors on OS was assessed using the log-rank test (univariate analyses) and Cox regression method (multivariate analysis). Results The median OS of untreated HCC was 2.3 months (95% confidence interval: 1.9–2.6). The 1, 3, 6, 12, 24 months OS rates were 84%, 42%, 21%, 9%, and 3%, respectively. All cases had died by 46 months. Male sex, advanced Child-Pugh class, the clinical presentation of ascites, cough, fatigue, and the presence of metastases were associated with poor survival (P<0.05 for all). In multivariate analysis; cough, presence of ascites, and Child-Pugh class were independent predictors of poor survival. Conclusion OS in untreated HCC in Egypt is very short. Many factors interact to produce this dismal survival. PMID:27508189

    Purpose. To investigate the prognostic factors for visual outcome in traumatic cataract patients. Methods. The demographic features of traumatic cataract patients in Central China were studied. The factors that might influence the visual outcome were analyzed. The sensitivity and specificity of OTS (ocular trauma score) in predicting VA were calculated. Results. The study enrolled 480 cases. 65.5% of patients achieved VA at >20/60. The factors associated with the final VA were initial VA, injury type, wound location, the way of cataract removal, and IOL implantation. The sensitivities of OTS in predicting the VA at NLP (nonlight perception), LP/HM (light perception/hand motion), and ≥20/40 were 100%. The specificity of OTS to predict the final VA at 1/200-19/200 and 20/200-20/50 was 100%. Conclusion. The prognostic factors were initial VA, injury type, wound location, cataract removal procedure, and the way of IOL implantation. The OTS has good sensitivity and specificity in predicting visual outcome in traumatic cataract patients in long follow-up.

    Cartilage tympanoplasty is an established procedure for tympanic membrane and attic reconstruction. Cartilage has been used as an ossiculoplasty material for many years. The aim of this study was to evaluate hearing results of costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for middle ear cholesteatoma and to determine the presence of prognostic factors. Candidates for this study were patients affected by middle ear cholesteatoma whose ossicular chain was reconstructed with a chondroprosthesis. 67 cases of ossiculoplasty with total (TORP) or partial (PORP) chondroprosthesis were performed between January 2011 and December 2013. Follow-up examination included micro-otoscopy and pure tone audiometry. The guidelines of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology Head and Neck Surgery were followed and pure-tone average (PTA) was calculated as the mean of 0.5, 1, 2 and 4 kHz thresholds. Statistical analysis was performed with ANOVA tests and regression models. Average air-bone gap (ABG) significantly improved from 39.2 dB HL (SD 9.1 dB HL) to 25.4 dB HL (SD 11 dB HL) (p < 0.001). Linear regression analysis showed that the only prognostic factor was the type of operation (p = 0.02). In fact, patients submitted to ICWT presented better post-operative ABG compared to CWDT. None of the other variables influenced the results. The present study proposes costal cartilage as material of choice when autologous ossicles are not available. The maintenance of the posterior canal wall was the only prognostic factor identified. PMID:26824916

    The psychological impact of an unfavorable genetic test result for counselees at risk for hereditary cancer seems to be limited: only 10-20 % of counselees have psychological problems after testing positive for a known familial mutation. The objective of this study was to find prognostic factors that can predict which counselees are most likely to develop psychological problems after presymptomatic genetic testing. Counselees with a 50 % risk of BRCA1/2 or Lynch syndrome completed questionnaires at three time-points: after receiving a written invitation for a genetic counseling intake (T1), 2-3 days after receiving their DNA test result (T2), and 4-6 weeks later (T3). The psychological impact of the genetic test result was examined shortly and 4-6 weeks after learning their test result. Subsequently, the influence of various potentially prognostic factors on psychological impact were examined in the whole group. Data from 165 counselees were analyzed. Counselees with an unfavorable outcome did not have more emotional distress, but showed significantly more cancer worries 4-6 weeks after learning their test result. Prognostic factors for cancer worries after genetic testing were pre-existing cancer worries, being single, a high risk perception of getting cancer, and an unfavorable test result. Emotional distress was best predicted by pre-existing cancer worries and pre-existing emotional distress. The psychological impact of an unfavorable genetic test result appears considerable if it is measured as "worries about cancer." Genetic counselors should provide additional guidance to counselees with many cancer worries, emotional distress, a high risk perception or a weak social network.

    Objective: To determine the prognostic factors affecting stereoacuity in patients with refractive accommodative esotropia (RAE) according to the results of long follow- up period. Methods: We reviewed the charts of 70 patients with RAE between the years 1985-2014. Patients were classified into three groups. G-1: Stereoacuity score 40 second/arc. G-2: Stereoacuity score >40 second/arc (50-3000). G-3: No binocular vision. Initiation age of RAE, duration of deviation, refractive error, amblyopia, amblyopia treatment, anisometropia, visual acuity, family history, angle of deviation for distance and near at each group and the prognostic factors affecting stereoacuity were analyzed. Results: The mean initiation age of RAE was 2.7±1.5 years, the mean age at first visit was 6.4±4.2 years. The mean follow up time was 7.3±4.4 years. Seven patients had 40 second/arc, 48 patients had 50 to 3000 second/arc stereoacuity, 15 patients had no binocular vision. Mean deviation for near was statistically higher in group 2 and 3. Visual acuity levels were higher in group 1 and 2 and was statistically significant. Low visual acuity (p=0.001, 0.008), higher angle of deviation at near (p=0.01), increased duration of deviation (p=0.01), presence of amblyopia (p=0.001) and irregularity of amblyopia treatment (p=0.01) were significantly related with poor stereoacuity. Conclusion: According to the prognostic factors low stereoacuity was mostly related with amblyopia as a result the late presentation of the patients in seeking care. Appropriate treatment as full refractive correction and amblyopia treatment during the RAE is important for development of good stereopsis. Also angle of deviation at near and duration of deviation can be a useful predictor for poor stereoacuity levels. PMID:26430408

    Background Analyze the most important prognostic factors when performing periapical surgery and compare the success rates of distinct authors. Introduction Periapical surgery is an approach to treat non-healing periapical lesions and it should be viewed as an extension of endodontic treatment and not as a separate entity. Material and Methods A search of articles published in Cochrane, PubMed (MEDLINE) and Scopus was conducted with the key words “prognostic factors”, “prognosis”, “periapical surgery”, “endodontic surgery” and “surgical endodontic treatment”. The inclusion criteria were articles including at least 10 patients, published in English, for the last 10 years. The exclusion criteria were nonhuman studies and case reports. Results 33 articles were selected from 321 initially found. Ten articles from 33 were excluded and finally the systematic review included 23 articles: 1 metaanalysis, 1 systematic review, 2 randomized clinical trials, 6 reviews, 12 prospective studies and 1 retrospective study. They were stratified according to their level of scientific evidence using the SORT criteria. Conclusions Factors associated with a better outcome of periapical surgery are patients ≤45 years old, upper anterior or premolar teeth, ≤10 sized lesions, non cystic lesions, absence of preoperative signs and symptoms, lesions without periodontal involvement, teeth with an adequate root-filling length, MTA as root-end filling material, uniradicular teeth, absence of perforating lesions, apical resection < 3 mm, teeth not associated to an oroantral fistula and teeth with only one periapical surgery. Key words:Prognostic factors, prognosis, periapical surgery, endodontic surgery and surgical endodontic treatment. PMID:26449431

    Human solid tumors accumulate multiple genetic abnormalities as they progress to advanced stages. Multiparameter flow cytometry measurements of individual cells within each tumor may be useful in describing the genetic pathways taken by individual tumors during the course of their genetic evolution. In this paper, we analyzed correlated cell-by-cell measurements of cell DNA content, HER-2/neu protein content, and ras protein content obtained by multiparameter flow cytometry studies of primary breast cancers from 92 patients. These laboratory findings were correlated with established clinical prognostic factors for each patient at the time of diagnosis, using a stepwise multiple analysis of variance (MANOVA). The stepwise MANOVA successively splits a group of patients into two mutually exclusive dissimilar groups, selecting the clinical prognostic factor that is most effective in doing so. Using this criterion, formation of the first three groups that were judged most dissimilar on the cytometry parameters was based on the number of positive nodes at the time of diagnosis. We show that ploidy, HER-2/neu protein content, and ras protein content, as measured by multiple parameter flow cytometry, are correlated with nodal status and other known clinical prognostic factors. The cell-by-cell multiparameter data suggest that for some individual tumors there are multiple genetic evolutionary pathways. Multiple genetic evolutionary pathways are also suggested by the MANOVA analysis. Focusing on the identification and analysis of genetic evolutionary pathways within individual tumors and across patients appears to offer a promising approach for defining the prognosis of early cancers. 9 refs., 2 figs., 7 tabs.

    In order to determine prognostic factors of lumbar disc surgery, we examined 107 patients who were conventionally operated on in a prospective, consecutive study. We analysed general data, the case history, the neurological examination at admission and all data from imaging examinations and therapy. In addition, all patients received a questionnaire based on the Low Back Outcome Score [9, 10]. The patients were re-examined after 2-8 months (103 days mean). According to their ratings on a pain grading scale, the patients were divided into a group with favorable and another with unfavorable results. These groups were analysed in relation to the patients' initial condition. At follow up, 88% of the patients had either completely recovered or their complaints had been relieved. According to the Low Back Outcome Score (LBOS), 64.5% went well. Used to evaluate the initial condition of the patients on admission the LBOS was able to predict favorable outcome in 68% and unfavorable outcome in 50%. To improve the prognostic value, we combined significant questions of the LBOS with the pain grading scale and significant prognostic factors to form a new prognostic score (Low Back Prognostic Score). With this new score we were able to predict a favorable outcome in 84% of our patients, and an unfavorable outcome in 71%. The Low Back Prognostic score seems to provide a sensitive method for predicting a favorable or unfavorable outcome for patients scheduled to undergo lumbar disc surgery. PMID:9577926

    The purpose of this study was to identify the main prognostic factors in patients with early-stage epithelial ovarian cancer. Data were extracted from 222 patients with initial stage (I–IIA) invasive epithelial ovarian cancer treated with primary surgery followed or not followed by adjuvant therapy, from 1 January 1980 to 31 December 2008, at the Division of Obstetrics and Gynecology, Spedali Civili, Brescia, Italy; the median follow-up was 79 months (SD ± 35,945, range 20–250 months). The negative prognostic factors that were statistically significant (p<0.050) in univariate analysis were grade 2, 3, and X (clear cell in our study); stage IB, IC, IIA; positive peritoneal cytology, age equal to/greater than 54; dense adhesions; capsule rupture (pre-operative or intra-operative) and endometrioid histotype (only for disease-free survival (DFS)). Positive cytology was strongly associated with peritoneal relapses, while adhesions were associated with pelvic relapses. A positive prognosis was associated with the mucinous histotype. Conservative treatment had been carried out in 52% of patients under 40 years of age, and we detected only two relapses and three completions of surgery after a few weeks among 31 women in total. Our study indicated a possible execution in patients with patients with cancer stage IA G1–G2 (p=0.030) or IC G1 (p=0.050), provided well staged. Adjuvant chemotherapy improved the survival of cancers that were not IA G1. The positive prognostic role of taxanes must be emphasised, when used in combination with platino. PMID:23781280

    Introduction Choroidal melanoma is the most common primary malignancy of the eye, which frequently metastasizes. The Cancer Registry of Slovenia reported the incidence of choroid melanoma from 1983 to 2009 as stable, at 7.8 cases/million for men and 7.4/million for women. The aim of the retrospective study was to determinate the prognostic factors of survival for choroidal melanoma patients in Slovenia. Patients and methods From January 1986 to December 2008 we treated 288 patients with malignant choroidal melanoma; 127 patients were treated by brachytherapy with beta rays emitting ruthenium-106 applicators; 161 patients were treated by enucleation. Results Patients with tumours thickness < 7.2 mm and base diameter < 16 mm were treated by brachytherapy and had 5- and 10-year overall mortality 13% and 32%, respectively. In enucleated patients, 5- and 10-year mortality was higher, 46% and 69%, respectively, because their tumours were larger. Thirty patients treated by brachytherapy developed local recurrence. Twenty five of 127 patients treated by brachytherapy and 86 of 161 enucleated patients developed distant metastases. Patients of age ≥ 60 years had significantly lower survival in both treatment modalities. For patients treated by brachytherapy the diameter of the tumour base and treatment time were independent prognostic factors for overall survival, for patients treated by enucleation age and histological type of tumour were independent prognosticators. In first few years after either of treatments, the melanoma specific annual mortality rate increased, especially in older patients, and then slowly decreased. Conclusions It seems that particularly younger patients with early tumours can be cured, whereby preference should be given to eyesight preserving brachytherapy over enucleation. PMID:27069456

    Several prognostic factors in oncology have been established over the years, such as performance status, tumor size, and disease stage. The identification of prognostic and predictive factors is becoming increasingly important in medical research, particularly as scientific discoveries have led to better understanding of diseases and genetics, resulting in tailored therapy. Advances in drug discovery and better understanding of the mechanism of action, may also identify factors that may be prognostic and/or predictive. Prognostic or predictive factors may include patient characteristics such as age, ethnicity, sex, or smoking status, disease characteristics such as disease stage or nodal status, and molecular markers such as HER2 amplification and K ras mutation.It can be challenging to distinguish whether a factor is prognostic or predictive, based on what is reported in the literature. This article is intended to help the reader assess whether a factor is prognostic and/or predictive.

    OBJECTIVE--To determine the prognosis and adverse prognostic factors in patients with retinal infarction due to presumed atheromatous thromboembolism or cardiogenic embolism. DESIGN--Prospective cohort study. SETTING--University hospital departments of clinical neurology. PATIENTS--99 patients with retinal infarction, without prior stroke, referred to a single neurologist between 1976 and 1986 and evaluated and followed up prospectively until death or the end of 1986 (mean follow up 4.2 years). INTERVENTIONS--Cerebral angiography (55 patients), aspirin treatment (37), oral anticoagulant treatment (eight), carotid endarterectomy (13), cardiac surgery (six), and peripheral vascular surgery (two). MAIN OUTCOME MEASURES--Death, stroke, coronary events, contralateral retinal infarction; survival analysis confined to 98 patients with retinal infarction due to presumed artheromatous thromboembolism or cardiogenic embolism (one patient with giant cell arteries excluded), and Cox's proportional hazards regression analysis, including age as a prognostic factor. RESULTS--During follow up 29 patients died (21 of vascular causes and eight of non-vascular or unknown causes), 10 had a first ever stroke, 19 had a coronary event, and only one developed contralateral retinal infarction. A coronary event accounted for more than half (59%) of the deaths whereas stroke was the cause of only one death (3%). Over the first five years after retinal infarction the actuarial average absolute risk of death was 8% per year; of stroke 2.5% per year (7.4% in the first year); of coronary events 5.3% per year, exceeding that of stroke; and of stroke, myocardial infarction, or vascular death 7.4% per year. Prognostic factors associated with an increased risk of death were increasing age, peripheral vascular disease, cardiomegaly, and carotid bruit. Adverse prognostic factors for serious vascular events were increasing age and carotid bruit for stroke, and increasing age, cardiomegaly, and carotid

    Introduction Telomere length, a marker of cell aging, seems to be affected by the same factors thought to be associated with breast cancer prognosis. Objective To examine associations of peripheral blood cell-measured telomere length with traditional and potential prognostic factors in breast cancer patients. Methods We conducted a cross-sectional analysis of data collected before surgery from 162 breast cancer patients recruited consecutively between 01/2011 and 05/2012, at a breast cancer reference center. Data on the main lifestyle factors (smoking, alcohol consumption, physical activity) were collected using standardized questionnaires. Anthropometric factors were measured. Tumor biological characteristics were extracted from pathology reports. Telomere length was measured using a highly reproducible quantitative PCR method in peripheral white blood cells. Spearman partial rank-order correlations and multivariate general linear models were used to evaluate relationships between telomere length and prognostic factors. Results Telomere length was positively associated with total physical activity (rs = 0.17, P = 0.033; Ptrend = 0.069), occupational physical activity (rs = 0.15, P = 0.054; Ptrend = 0.054) and transportation-related physical activity (rs = 0.19, P = 0.019; P = 0.005). Among post-menopausal women, telomere length remained positively associated with total physical activity (rs = 0.27, P = 0.016; Ptrend = 0.054) and occupational physical activity (rs = 0.26, P = 0.021; Ptrend = 0.056) and was only associated with transportation-related physical activity among pre-menopausal women (rs = 0.27, P = 0.015; P = 0.004). No association was observed between telomere length and recreational or household activities, other lifestyle factors or traditional prognostic factors. Conclusions Telomeres are longer in more active breast cancer patients. Since white blood cells are involved in anticancer immune responses, these findings suggest that even regular low

    The prevalence of atopic diseases, including allergic rhinitis, asthma bronchiale and atopic dermatitis is increasing both in children and adults at different parts of the world. Atopic dermatitis is a chronic inflammatory skin disease affecting mostly children, but the atopic trait continues, not only for later respiratory allergies, but also for skin symptoms in adulthood. In this form dry skin, flexural lichenification, head and neck dermatitis, hand dermatitis are typical. The exact etiology of atopic dermatitis is unknown, in the background interactions of genetical predisposition, skin barrier defects and immunological and environmental factors can be verified. In the complex approach of atopic dermatitis, a pivotal role is ascribed to the evaluation and possibly the elimination of provoking factors, like gender, family structure, clothing, aero-, alimentary and contact allergens, psychosocial stress, migration, infections, and personal home environment. Authors review clinical manifestations, triggering and prognostic factors of the adulthood atopic dermatitis. PMID:17344114

    Statistically sound experimental design in pharmacology studies ensures that the known prognostic factors, if any, are equally represented across investigational groups to avoid bias and imbalance which could render the experiment invalid or lead to false conclusions. Complete randomization can be effective to reduce bias in the created groups especially in large sample size situations. However, in small studies which involve only few treatment subjects, as in preclinical trials, there is a high chance of imbalance. The effects of this imbalance may be removed through covariate analysis or prevented with stratified randomization, however small studies limit the number of covariates to be analyzed this way. The problem is accentuated when there are multiple baseline covariates with varying scales and magnitudes to be considered in the randomization, and creating a balanced solution becomes a combinatorial challenge. Our method, IRINI, uses an optimization technique to achieve treatment to subject group allocation across multiple prognostic factors concurrently. It ensures that the created groups are equal in size and statistically comparable in terms of mean and variance. This method is a novel application of genetic algorithms to solve the allocation problem and simultaneously ensure quality, speed of the results and randomness of the process. Results from preclinical trials demonstrate the effectiveness of the method.

    ABSTRACT Background: Despite recent advances in diagnosis and treatment, esophageal cancer still has high mortality. Prognostic factors associated with patient and with disease itself are multiple and poorly explored. Aim: Assess prognostic variables in esophageal cancer patients. Methods: Retrospective review of all patients with esophageal cancer in an oncology referral center. They were divided according to histological diagnosis (444 squamous cell carcinoma patients and 105 adenocarcinoma), and their demographic, pathological and clinical characteristics were analyzed and compared to clinical stage and overall survival. Results: No difference was noted between squamous cell carcinoma and esophageal adenocarcinoma overall survival curves. Squamous cell carcinoma presented 22.8% survival after five years against 20.2% for adenocarcinoma. When considering only patients treated with curative intent resection, after five years squamous cell carcinoma survival rate was 56.6 and adenocarcinoma, 58%. In patients with squamous cell carcinoma, poor differentiation histology and tumor size were associated with worse oncology stage, but this was not evidenced in adenocarcinoma. Conclusion: Weight loss (kg), BMI variation (kg/m²) and percentage of weight loss are factors that predict worse stage at diagnosis in the squamous cell carcinoma. In adenocarcinoma, these findings were not statistically significant. PMID:27759773

    Morbidity and mortality after emergency procedures in 105 patients with perforated colonic diverticulitis were evaluated in a retrospective study. In different stages of diverticulitis (Hinchey classification: I, 8.6%; II, 14.3%; III, 57.1%; IV, 20.0%) mortality was 12.4%. Preoperative sepsis syndrome with leucopenia and disturbed liver function, cardiac risk factors and obesity were independent prognostic factors in multiple logistic regression. Accompanied by immunosuppression the mortality rate remarkably increased to 33%. The stage of peritonitis showed no influence on the prognosis. In multivariate analysis, surgical procedure (primary resection 12.4%. Hartmann's procedure 61.9%, non-resection procedures 25.7%) showed influence only on increased general complications.

    The objective of this study was to determine the combination of left ventricular ejection fraction (LVEF) and individual electrocardiographic parameters related to abnormal depolarization/repolarization or baroreceptor sensitivity that had the best predictive value for major adverse cardiac events (MACE) in patients with acute coronary syndrome (ACS). Patients with ACS who underwent coronary angiography and percutaneous coronary intervention (PCI) were included in this prospective study. Ventricular late potential (VLP), heart rate turbulence (HRT), heart rate variability (HRV), and T wave alternans (TWA) parameters were measured using 24 h Holter monitoring 2-4 weeks after onset of ACS. Initial and follow-up LVEF was measured by ultrasound. Patients were followed for at least 6 months to record the occurrence of MACE. Models using combinations of the individual independent prognostic factors found by multivariate analysis were then constructed to use for estimation of risk of MACE. In multivariate analysis, VLP measured as QRS duration, HRV measured as standard deviation of normal RR intervals, and followup LVEF, but none of the other parameters studied, were independent risk factors for MACE. Areas under ROC curve (AUCs) for combinations of 2 or all 3 factors ranged from 0.73 to 0.76. Combinations of any of the three independent risk factors for MACE in ACS patients with PCI improved prediction and, because these risk factors were obtained non-invasively, may have future clinical usefulness.

    INTRODUCTION Ovarian cancer has a high mortality and delayed diagnosis. Inflammation is a risk factor for ovarian cancer, and the inflammatory response is involved in almost all stages of tumor development. Immunohistochemical staining in stroma and epithelium of a panel of cytokines in benign and malignant ovarian neoplasm was evaluated. In addition, immunostaining was related to prognostic factors in malignant tumors. METHOD The study group comprised 28 ovarian benign neoplasias and 28 ovarian malignant neoplasms. A panel of cytokines was evaluated by immunohistochemistry (Th1: IL-2 and IL-8; Th2: IL-5, IL-6, and IL-10; and TNFR1). Chi-square test with Yates’ correction was used, which was considered significant if less than 0.05. RESULTS TNFR1, IL-5, and IL-10 had more frequent immunostaining 2/3 in benign neoplasms compared with malignant tumors. Malignant tumors had more frequent immunostaining 2/3 for IL-2 in relation to benign tumors. The immunostaining 0/1 of IL 8 was more frequent in the stroma of benign neoplasms compared with malignant neoplasms. Evaluation of the ovarian cancer stroma showed that histological grade 3 was significantly correlated with staining 2/3 for IL-2 (P = 0.004). Women whose disease-free survival was less than 2.5 years had TNFR1 stromal staining 2/3 (P = 0.03) more frequently. CONCLUSION IL-2 and TNFR1 stromal immunostaining are related prognostic factors in ovarian cancer and can be the target of new therapeutic strategies. PMID:27512342

    In this review, we will examine various molecular biomarkers for their potential to serve as independent prognostic factors for predicting survival outcome in postoperative patients with progressive intrahepatic cholangiocarcinoma. Specific rodent models of intrahepatic cholangiocarcinoma that mimic relevant cellular, molecular, and clinical features of the human disease are also described, not only in terms of their usefulness in identifying molecular pathways and mechanisms linked to cholangiocarcinoma development and progression, but also for their potential value as preclinical platforms for suggesting and testing novel molecular strategies for cholangiocarcinoma therapy. Last, recent studies aimed at addressing the role of desmoplastic stroma in promoting intrahepatic cholangiocarcinoma progression are highlighted in an effort to underline the potential value of targeting tumor stromal components together with that of cholangiocarcinoma cells as a novel therapeutic option for this devastating cancer.

    Community-acquired meningitis is a serious disease that is associated with high morbidity and mortality. The purpose of this study was to investigate the gender differences involved with the clinical presentations of and prognostic factors for this disease. We conducted a retrospective study of 619 adults diagnosed with community-acquired meningitis in Houston, Texas, who were hospitalized between 2005 and 2010. Patients were categorized as male or female. Those who were evaluated to have a Glasgow Outcome Scale score of four or less were classified to have an adverse clinical outcome. Males consisted of 47.2% (292/619) of the total cohort, and more often presented with coexisting medical conditions, fever, abnormal microbiology results, and abnormalities on head computed tomography. Females more often presented with nuchal rigidity. On logistic regression, fever, CSF glucose <45 mg/dL, and an abnormal neurological examination were predictors of an adverse outcome in male patients, while age greater than 60 years and an abnormal neurological examination were associated with a poor prognosis in female patients. Thus, community-acquired meningitis in males differs significantly from females in regards to comorbidities, presenting symptoms and signs, abnormal laboratory and imaging analysis, and predictors of adverse clinical outcomes.

    We conducted a comprehensive analysis of 28 recurrently mutated genes in acute myeloid leukemia (AML) in 271 patients with de novo AML. Co-mutations were frequently detected in the intermediate cytogenetic risk group, at an average of 2.76 co-mutations per patient. When assessing the prognostic impact of these co-mutations in the intermediate cytogenetic risk group, overall survival (OS) was found to be significantly shorter (P=0.0006) and cumulative incidence of relapse (CIR) significantly higher (P=0.0052) in patients with complex molecular genetic abnormalities (CMGAs) involving three or more mutations. This trend was marked even among patients aged ⩽65 years who were also FLT3-ITD (FMS-like tyrosine kinase 3 internal tandem duplications)-negative (OS: P=0.0010; CIR: P=0.1800). Moreover, the multivariate analysis revealed that CMGA positivity was an independent prognostic factor associated with OS (P=0.0007). In stratification based on FLT3-ITD and CEBPA status and 'simplified analysis of co-mutations' using seven genes that featured frequently in CMGAs, CMGA positivity retained its prognostic value in transplantation-aged patients of the intermediate cytogenetic risk group (OS: P=0.0002. CIR: P<0.0001). In conclusion, CMGAs in AML were found to be strong independent adverse prognostic factors and simplified co-mutation analysis to have clinical usefulness and applicability.

    The prognosis of Guillain-Barré syndrome (GBS) is not as good as might be expected. Among GBS patients, 30% do not respond to intravenous immunoglobulin therapy (IVIg) and 10% may worsen after initial treatment (treatment-related fluctuation). Recent prospective trials show that 16% of GBS patients are unable to walk independently a year after onset of the disease. The prognosis of GBS is influenced by clinical, electrophysiological and biological factors, of which the clinical factors are most important. The Erasmus GBS Respiratory Insufficiency Score (EGRIS) and the modified EGOS (Erasmus GBS Outcome Score) are very useful for prediction of mechanical ventilation or aided walking. A small increase in serum IgG (delta IgG) two weeks after IVIg treatment is useful as a biological prognostic marker that is significantly associated with slow recovery and aided walking at 6 months. Use of these factors makes it possible to predict the prognosis of GBS patients, and to identify patients with a poor prognosis in the early phase of the disease and provide these patients with intensive treatment. An accurate prediction of the level of disability is important for improvement of the prognosis of GBS.

    Metastatic lymph nodes (LN) are an adverse prognostic factor in head and neck squamous cell carcinoma (SCC). In this study, we tested the hypothesis that nodal metastases have reduced impact on survival in tonsil cancer in the HPV-predominant era. Incidence and mortality data of tonsil and oral cavity SCC between 1988 and 2007 were obtained from the SEER database. Based on published literature, we considered cases of tonsil cancer from 1988 to 1997 as the pre-HPV cohort (N = 752), and 1998-2007 as the HPV-predominant cohort (N = 2,755). Comparing the two cohorts, Kaplan-Meier 5-year overall survival (OS) for tonsil SCC improved from 54.0 to 74.3 % (p < 0.0001), and cancer-specific survival (CSS) improved from 66.0 to 82.9 % (p < 0.0001). Stratifying by LN involvement showed improved OS in the HPV-predominant cohort with one (63.6 vs. 79.7 %, p < 0.0001), two to three (54.2 vs. 75.9 %, p < 0.0001), four to eight (40.3 vs. 68.9 %, p < 0.0001), and greater than eight positive nodes (25.5 vs. 41.9 %, p < 0.0001). While metastatic LNs still negatively affect prognosis, their impact on OPC survival has diminished in the HPV-predominant era. This finding provides a rationale for additional studies of the prognostic significance of LN metastases in OPC cohorts of defined HPV status, and supports the concept that HPV-related OPC is a disease distinct from "classical" OPC, with unique prognostic features.

    Objective Metastatic lymph nodes (LN) are an adverse prognostic factor in head and neck squamous cell carcinoma (SCC). In this study, we tested the hypothesis that nodal metastases have reduced impact on survival in tonsil cancer in the HPV-predominant era. Methods Incidence and mortality data of tonsil and oral cavity SCC between 1988 and 2007 was obtained from the SEER database. Based on published literature, we considered cases of tonsil cancer from 1988–1997 the pre-HPV cohort (N=752), and 1998–2007 as the HPV-predominant cohort (N=2,755). Results Comparing the two cohorts, Kaplan-Meier five-year overall survival (OS) for tonsil SCC improved from 54.0% to 74.3% (p<0.0001), and cancer-specific survival (CSS) improved from 66.0 to 82.9% (p<0.0001). Stratifying by LN involvement showed improved OS in the HPV-predominant cohort with one (63.6 vs. 79.7%, p<0.0001), two to three (54.2 vs. 75.9%, P<0.0001), four to eight (40.3 vs. 68.9%, p<0.0001), and greater than eight positive nodes (25.5 vs. 41.9%, p<0.0001). Conclusion While metastatic LNs still negatively affect prognosis, their impact on OPC survival has diminished in the HPV-predominant era.

    Adverse drug reactions (ADR} are the downside of active pharmacotherapies and can only partially be avoided. Risk factors have been identified for certain ADR which should be taken into account for the choice and dosing of critical drugs. Medical staff have a legal obligation to report severe ADR and ADR caused by newly licensed drugs. Such reports are important for monitoring the safety of drugs that are on the market. PMID:26654809

    Objectives To discuss the effect of certain factors on the occurrence of Adverse Drug Reactions (ADRs). Data Sources A systematic review of the literature in the period between 1991 and 2012 was made based on PubMed, the Cochrane database of systematic reviews, EMBASE and IDIS. Key words used were: medication error, adverse drug reaction, iatrogenic disease factors, ambulatory care, primary health care, side effects and treatment hazards. Summary Many factors play a crucial role in the occurrence of ADRs, some of these are patient related, drug related or socially related factors. Age for instance has a very critical impact on the occurrence of ADRs, both very young and very old patients are more vulnerable to these reactions than other age groups. Alcohol intake also has a crucial impact on ADRs. Other factors are gender, race, pregnancy, breast feeding, kidney problems, liver function, drug dose and frequency and many other factors. The effect of these factors on ADRs is well documented in the medical literature. Taking these factors into consideration during medical evaluation enables medical practitioners to choose the best drug regimen. Conclusion Many factors affect the occurrence of ADRs. Some of these factors can be changed like smoking or alcohol intake others cannot be changed like age, presence of other diseases or genetic factors. Understanding the different effects of these factors on ADRs enables healthcare professionals to choose the most appropriate medication for that particular patient. It also helps the healthcare professionals to give the best advice to patients. Pharmacogenomics is the most recent science which emphasizes the genetic predisposition of ADRs. This innovative science provides a new perspective in dealing with the decision making process of drug selection. PMID:24648818

  2. Unexpected gallbladder cancer: Surgical strategies and prognostic factors.

    Gallbladder cancer is the most common tumor of the biliary tract and it is associated with a poor prognosis. Unexpected gallbladder cancer is a cancer incidentally discovered, as a surprise, at the histological examination after cholecystectomy for gallstones or other indications. It is a potentially curable disease, with an intermediate or good prognosis in most cases. An adequate surgical strategy is mandatory to improve the prognosis and an adjunctive radical resection may be required depending on the depth of invasion. If the cancer discovered after cholecystectomy is a pTis or a pT1a, a second surgical procedure is not mandatory. In the other cases (pT1b, pT2 and pT3 cancer) a re-resection (4b + 5 liver segmentectomy, lymphadenectomy and port-sites excision in some cases) is required to obtain a radical excision of the tumor and an accurate disease staging. The operative specimens of re-resection should be examined by the pathologist to find any "residual" tumor. The "residual disease" is the most important prognostic factor, significantly reducing median disease-free survival and disease-specific survival. The other factors include depth of parietal invasion, metastatic nodal disease, surgical margin status, cholecystectomy for acute cholecystitis, histological differentiation, lymphatic, vascular and peri-neural invasion and overall TNM-stage.

    Introduction. The small renal masses (SRMs) have increased over the past two decades due to more liberal use of imaging techniques. SRMs have allowed discussions regarding their prognostic, diagnosis, and therapeutic approach. Materials and methods. Clinical presentation, incidental diagnosis, and prognosis factors of SRMs are discussed in this review. Results. SRMs are defined as lesions less than 4 cm in diameter. SRM could be benign, and most malignant SMRs are low stage and low grade. Clinical symptoms like hematuria are very rare, being diagnosed by chance (incidental) in most cases. Size, stage, and grade are still the most consistent prognosis factors in (RCC). An enhanced contrast SRM that grows during active surveillance is clearly malignant, and its aggressive potential increases in those greater than 3 cm. Clear cell carcinoma is the most frequent cellular type of malign SRM. Conclusions. Only some SRMs are benign. The great majority of malign SRMs have good prognosis (low stage and grade, no metastasis) with open or laparoscopic surgical treatment (nephron sparing techniques). Active surveillance is an accepted attitude in selected cases. PMID:19165347

    OBJECTIVE: To identify prognostic factors of postoperative functional outcomes. METHODS: Retrospective case series evaluating patients undergoing rotator cuff repair, analyzed by the UCLA score (pre and 12-month postoperative) and Magnetic Resonance Imaging (preoperative). Patients' intrinsic variables related to the injury and intervention were evaluated. Multivariate linear regression analysis was performed to determine variables impact on postoperative functional assessment. RESULTS: 131 patients were included. The mean UCLA score increased from 13.17 ± 3.77 to 28.73 ± 6.09 (p<0,001). We obtained 65.7% of good and excellent results. Age (r= 0.232, p= 0.004) and reparability of posterosuperior injuries (r= 0.151, p= 0.043) correlated with the functional assessment at 12 months. After multivariate linear regression analysis, only age was associated (p = 0.008). CONCLUSIONS: The surgical treatment of rotator cuff tears lead to good and excellent results in 65.6% of patients. Age was an independent predictor factor with better clinical outcomes by UCLA score in older patients. Level of Evidence IV, Case Series. PMID:26207092

    VEGF-C is regarded as one of the most efficient factors in regulating lymphangiogenesis. The aim of this study was to better understand the role of VEGF-C in the progression of ovarian cancer and to assess its diagnostic and prognostic significance. A total of 109 patients with ovarian cancer, 76 patients with benign ovarian diseases, and 50 healthy controls were recruited in this study. Serum levels of VEGF-C were determined by ELISA method. The results showed that serum levels of VEGF-C were significantly higher in the patients with ovarian cancer than those with benign ovarian diseases and healthy controls (P<0.01). Serum level of VEGF-C was correlated with FIGO stage, lymph node metastasis, tumor resectability, and survival of the patients (P<0.05). The areas of receiver operating curves of VEGF-C were higher than those of CA125 in different screening groups. Analysis using the Kaplan-meier method indicated that patients with high VEGF-C had significantly shorter overall survival time than those with low VEGF-C (P<0.0001). In a multivariate analysis along with clinical prognostic parameters, serum VEGF-C was identified as an independent adverse prognostic variable for overall survival. These results indicated that serum VEGF-C may be a clinically useful indicator for diagnostic and prognostic evaluation in ovarian cancer patients.

    Purpose: To investigate treatment outcome and prognostic factors after radiation therapy in patients with medulloblastomas (MB). Methods and Materials: Sixty-six patients with histologically confirmed MB were treated at University Hospital of Heidelberg between 1985 and 2009. Forty-two patients (64%) were pediatric ({<=}18 years), and 24 patients (36%) were adults. Tumor resection was performed in all patients and was complete in 47%. All patients underwent postoperative craniospinal irradiation (CSI) delivering a median craniospinal dose of 35.5 Gy with additional boosts to the posterior fossa up to 54.0 Gy. Forty-seven patients received chemotherapy, including 21 in whom chemotherapy was administered before CSI. Statistical analysis was performed using the log-rank test and the Kaplan-Meier method. Results: Median follow-up was 93 months. Overall survival (OS) and local and distant progression-free survival (LPFS and DPFS) were 73%, 62%, and 77% at 60 months. Both local and distant recurrence predisposed for significantly reduced OS. Macroscopic complete tumor resection, desmoplastic histology and early initiation of postoperative radiation therapy within 28 days were associated with improved outcome. The addition of chemotherapy did not improve survival rates. Toxicity was moderate. Conclusions: Complete resection of MB followed by CSI yields long survival rates in both children and adults. Delayed initiation of CSI is associated with poor outcome. Desmoplastic histology is associated with improved survival. The role of chemotherapy, especially in the adult population, must be further investigated in clinical studies.

    Purpose. Liposarcoma is extremely rare in the pediatric population. To identify prognostic factors and determine treatment outcomes, we reviewed our institutional experience with pediatric liposarcoma. Methods. We retrospectively reviewed all pediatric patients (age <22 years) with confirmed liposarcoma treated at Memorial Sloan-Kettering Cancer Center. Histologic subtype, tumor location, margin status, recurrence, and adjuvant therapy were analyzed and correlated with overall survival. Results. Thirty-four patients (56% male) with a median age of 18.1 years were identified. Twenty-two (65%) had peripheral tumors and 12 (35%) had centrally located tumors. Histologically, 29 (85%) tumors were low grade, and 5 (15%) were high grade pleomorphic. Eleven (32%) had recurrent disease, 9 patients with central tumors and 2 patients with peripheral lesions. Eight deaths occurred, all in patients with central disease. Five-year overall survival was 78%, with a median follow-up time of 5.4 years (range, 0.3–30.3 years). Tumor grade (P = .003), histologic subtype (P = .01), and primary location (P < .001) all correlated with survival, as did stage (P < .001) and margin status (P = .001). Conclusions. Central location of the primary tumor, high tumor grade, and positive surgical margins are strongly correlated with poor survival in pediatric patients with liposarcoma. PMID:22991488

    Abstract Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL. From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed. In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4. High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not

    The purpose of this study was to analyze GPS related adverse events such as accidents and incidents (A/I), Aviation Safety Reporting System (ASRS) reports and Pilots Deviations (PDs) to create a framework for developing a human factors risk awareness program. Although the occurrence of directly related GPS accidents is small the frequency of PDs and ASRS reports indicated there is a growing problem with situational awareness in terminal airspace related to different types of GPs operational issues. This paper addresses the findings of the preliminary research and a brief discussion of some of the literature on related GPS and automation issues.

    Introduction The aim of the present study was to evaluate the influence of clinicopathological factors including age, gender, tumor grade, tumor stage, lymphovascular invasion (LVI), tumor necrosis and previous history of non-muscle invasive bladder cancer on outcomes of patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). Material and methods A total of 60 patients who underwent radical nephroureterectomy for upper tract urothelial carcinoma at our institute between 2005 to 2012 were included in our study. Univariate and multivariate analysis was performed using the Kaplan-Meier method, log rank statistics, the chi-square test and Cox regression models. Results The mean length of follow-up time was 33.3 months. There were 27 (45%) patients alive with the disease, whereas 33 (55%) were dead. In 19 cases (31.7%) the tumor grade was low, while in 41 cases (68.3%) it was high. Lymphovascular invasion was observed in 28 (46.7%) cases. Tumor necrosis was registered in 14 patients (23.3%). From the patients with LVI, 3 (9.6%) were alive, whereas from the patients negative for LVI, 75% were alive. Significant relationship was found between gender and grading and between positive LVI and low grading. Conclusions Day case Variables such as gender, grading, tumor stage, LVI and tumor necrosis were all demonstrated to be significant independent prognostic factors for the overall survival. On the multivariate analysis only LVI remained statistically significant, which may explain the different clinical course in patients and could be considered as a part of pathological reporting and treatment planning for the future.

    A paucity of data exists concerning the presentation, natural course and outcome of extramedullary plasmcytoma (EMP). It is difficult to determine the optimal treatment strategy and prognostic factors for EMP. We present an additional case of laryngeal EMP and systemic review relevant reports in the English and Chinese literature. We found, to our knowledge, 147 cases in larynx in the English-language literature and Chinese-literature. The most common treatment modality was radiotherapy alone. The mean survival duration was ~184 months, and the 5- and 10- year survival rates were 76.1% and 67.4%, respectively. The univariate analysis suggested that progression to multiple myeloma and amyloid deposits may be poor prognostic factors. The multivariate analysis suggested that only progression to multiple myeloma may be a poor prognostic factor. Laryngeal EMP is uncommon. Progression to multiple myeloma may be a poor prognostic factor. PMID:26045749

    Cardiovascular disease (CVD) is the leading health threat to American women. In addition to established risk factors for hypertension, hyperlipidemia, diabetes, smoking, and obesity, adverse pregnancy outcomes (APOs) including pre-eclampsia, eclampsia, and gestational diabetes are now recognized as factors that increase a woman’s risk for future CVD. CVD risk factor burden is disproportionately higher in those of low socioeconomic status and in ethnic/racial minority women. Since younger women often use their obstetrician/gynecologist as their primary health provider, this is an opportune time to diagnose and treat CVD risk factors early. Embedding preventive care providers such as nurse practitioners or physician assistants within OB/GYN practices can be considered, with referral to family medicine or internist for ongoing risk assessment and management. The American Heart Association (AHA)/American Stroke Association (ASA) stroke prevention guidelines tailored to women recommend that women with a history of pre-eclampsia be evaluated for hypertension and other CVD risk factors within 6 months to 1 year post-partum. Given the burden and impact of CVD on women our society, the entire medical community must work to establish feasible practice and referral patterns for assessment and treatment of CVD risk factors.

    We reviewed our 41-year experience with tumors of the submandibular gland to determine what factors influence outcome and their implications for treatment. The most common benign neoplasm was pleomorphic adenoma (21), while among malignant tumors the adenoid cystic variety (37) predominated. For the 86 patients who had malignant tumors, the 2- and 5-year survivals by the life table method were 82% and 69%, respectively. For patients with malignant tumors, histology, size, perineural invasion, and prior treatment did not affect overall survival. Factors adversely affecting outcome were extraglandular soft-tissue extension and lymph node metastasis. Local-regional control was enhanced in patients with soft-tissue extension if they were treated by surgery followed by radiotherapy rather than by surgery alone.

    Identification of prognostic factors for surgery in patients with sciatica is important to be able to predict surgery in an early stage. Identification of prognostic factors predicting persistent pain, disability and recovery are important for better understanding of the clinical course, to inform patient and physician and support decision making. Consequently, we aimed to systematically review prognostic factors predicting outcome in non-surgically treated patients with sciatica. A search of Medline, Embase, Web of Science and Cinahl, up to March 2012 was performed for prospective cohort studies on prognostic factors for non-surgically treated sciatica. Two reviewers independently selected studies for inclusion and assessed the risk of bias. Outcomes were pain, disability, recovery and surgery. A best evidence synthesis was carried out in order to assess and summarize the data. The initial search yielded 4392 articles of which 23 articles reporting on 14 original cohorts met the inclusion criteria. High clinical, methodological and statistical heterogeneity among studies was found. Reported evidence regarding prognostic factors predicting the outcome in sciatica is limited. The majority of factors that have been evaluated, e.g., age, body mass index, smoking and sensory disturbance, showed no association with outcome. The only positive association with strong evidence was found for leg pain intensity at baseline as prognostic factor for subsequent surgery.

    Aim The study of candidemia in cancer patients has been limited. This retrospective study aims to investigate the epidemiologic characteristics and prognostic factors of candidemia among cancer patients. Materials and Methods From 2009 to 2012, cancer patients with candidemia were identified at a hospital in Taiwan. The medical records of all patients with bloodstream infections due to Candida species were retrospectively reviewed. Results During the four-year period, a total of 242 episodes of candidemia were identified among cancer patients. Half of these patients were classified as elderly (≥65 years old), and more than 95% of the candidemia episodes were classified as healthcare-associated infections. Among the 242 cancer patients with candidemia, head and neck cancer was the most common, followed by gastrointestinal tract and lung cancer. Additionally, most of the patients had variable underlying conditions, such as the presence of CVC (99%) or prior exposure to broad-spectrum antibiotics (93%) and were receiving an immunosuppressant (86%). Overall, C. albicans (n = 132, 54.5%) was the most common pathogen, followed by C. tropicalis (n = 52, 21.5%), C. parapsilosis (n = 38, 15.7%), and C. glabrata (n = 29, 12.0%). Seventeen patients had polycandidal candidemia, and 77 patients had concomitant bacteremia. Approximately one-third of the patients required admission to the intensive care unit (ICU) or mechanical ventilation, and the overall in-hospital mortality was 50.8%. Multivariable analysis showed that the in-hospital mortality was significantly associated with only the non-use of antifungal agents and acute respiratory failure (P<.001). Conclusions Candidemia can develop in patients with both solid cancer and hematological malignancy, especially for patients with underlying conditions. Overall, the associated morbidity and mortality due to Candidemia remain high. It was also determined that the non-use of antifungal agents and acute

    The aim of this study is to determine if breast conservative treatment is justified for patients with a positive family history of breast cancer and to investigate whether they have a worse prognosis. We performed a prospective cohort study of breast cancer patients, treated with breast conservative treatment with radiotherapy at the Radiotherapy Department of the Medisch Spectrum Twente. Between 1984 and 1996, 1204 patients with T1 and T2 < or =3 cm were treated. Family history (FH) was recorded according to first degree relative (FDR). Treatment consisted of lumpectomy with axillary dissection followed by radiotherapy to the whole breast with a boost to the primary area. Adjuvant systemic therapy was given to patients with positive nodes. A positive FH was noted in 243 (20.5%) patients, of whom 208 (17.6%) had one FDR, and 35 (3.0%) > or =2 FDRs. The local recurrence rate was 4.1%, with similar rates for all groups. In young patients, < or =40 years, a significant relation between local recurrence and FH was found. The distant metastasis rate was 15.5%, with the lowest rate (5.7%) among patients with > or =2 FDRs. Patients with a positive FH had significantly more contralateral tumours. The 5-year corrected survival was 91.3%. Among patients with a positive FH, a 5-year corrected survival of 91% was observed and the survival 100% among patients with one and > or =2 FDR. Family history is not a contraindication for breast conservative treatment and is not associated with a worse prognosis. Family history is not a prognostic factor for local recurrence rate in patients older than 40 years. PMID:14731704

    The aim of this study is to determine if breast conservative treatment is justified for patients with a positive family history of breast cancer and to investigate whether they have a worse prognosis. We performed a prospective cohort study of breast cancer patients, treated with breast conservative treatment with radiotherapy at the Radiotherapy Department of the Medisch Spectrum Twente. Between 1984 and 1996, 1204 patients with T1 and T2 < or =3 cm were treated. Family history (FH) was recorded according to first degree relative (FDR). Treatment consisted of lumpectomy with axillary dissection followed by radiotherapy to the whole breast with a boost to the primary area. Adjuvant systemic therapy was given to patients with positive nodes. A positive FH was noted in 243 (20.5%) patients, of whom 208 (17.6%) had one FDR, and 35 (3.0%) > or =2 FDRs. The local recurrence rate was 4.1%, with similar rates for all groups. In young patients, < or =40 years, a significant relation between local recurrence and FH was found. The distant metastasis rate was 15.5%, with the lowest rate (5.7%) among patients with > or =2 FDRs. Patients with a positive FH had significantly more contralateral tumours. The 5-year corrected survival was 91.3%. Among patients with a positive FH, a 5-year corrected survival of 91% was observed and the survival 100% among patients with one and > or =2 FDR. Family history is not a contraindication for breast conservative treatment and is not associated with a worse prognosis. Family history is not a prognostic factor for local recurrence rate in patients older than 40 years.

  1. Alexithymia as a prognostic risk factor for health problems: a brief review of epidemiological studies

    PubMed Central

    2012-01-01

    The number of articles on alexithymia has been steadily increasing since the word “alexithymia” was coined in the 1970s to denote a common characteristic that is observed among classic psychosomatic patients in whom therapy was unsuccessful. Alexithymia, a disorder of affect regulation, has been suggested to be broadly associated with various mental and physical health problems. However, most available evidence is based on anecdotal reports or cross-sectional observations. To clarify the predictive value of alexithymia for health problems, a systematic review of prospective studies was conducted. A search of the PubMed database identified 1,507 articles on “alexithymia” that were published by July 31, 2011. Among them, only 7 studies examined the developmental risks of alexithymia for health problems among nonclinical populations and 38 studies examined the prognostic value of alexithymia among clinical populations. Approximately half of the studies reported statistically significant adverse effects, while 5 studies demonstrated favorable effects of alexithymia on health outcomes; four of them were associated with surgical interventions and two involved cancer patients. The studies that showed insignificant results tended to have a small sample size. In conclusion, epidemiological evidence regarding alexithymia as a prognostic risk factor for health problems remains un-established. Even though alexithymia is considered to be an unfavorable characteristic for disease control and health promotion overall, some beneficial aspects are suggested. More prospective studies with sufficient sample sizes and follow-up period, especially those involving life course analyses, are needed to confirm the contribution of alexithymia to health problems.

    An understanding of prognosis in cancer medicine is important for patient care, research and cancer control programs. In prostate cancer, prognostic (predictive) factors are particularly important given the marked heterogeneity of this disease at clinical, morphologic and biomolecular levels. Clinical stage and histologic grade have historically played major roles in defining heterogeneity in prostate cancer. More recently, serum prostate-specific antigen measurement has assumed a significant prognostic role. Over the last two decades there has been an explosion of research into biomarkers, many of which have been purported to have prognostic significance. In this paper we present an overview of the various consensus initiatives that have transpired over the last dozen years. Criteria for evaluating prognostic factors and classifications of predictive factors have emerged that have proven useful and advanced our understanding of the biology of prostate cancer. The results of these consensus initiatives form a foundation on which the current international consultation on prognosis (prediction) in prostate cancer is built. Advances in our understanding of the new and promising prognostic factors will require a more rigorous evidence-based approach to the analysis of published studies. Furthermore, appropriate mathematical models for the analysis of the multiple factors that influence a prognostic system will have to be employed.

    The aim of this study was to assess the demographic, clinic data, prognostic factors and treatment/follow-up results of children who were diagnosed with Hodgkin lymphoma and followed in our center of Pediatric Oncology, Kocaeli University Medical Faculty, Kocaeli, Turkey, for 10 years. This retrospective study evaluated 41 patients with Hodgkin lymphoma who were younger than 18 years-old. All patients were treated with risked adapted ABVD (Adriamycin, Bleomycin, Vincristine, Dacarbazine) chemotherapy and also received involved field radiotherapy. Thirty-two patients (78%) were males and 9 (22%) were females, with a mean age of 10.7±4.0 years. The histopathological diagnosis was mixed cellular type in 51.2% of the patients. B symptoms (unexplained fever, unexplained weight loss, drenching night sweats) were present in 53.7% of the patients and 36.6% of the patients were at advanced stage at the time of the diagnosis. The 3-year overall and event-free survival rates were 88% and 5-year overall and event-free survival rates were 88%, 78%. Age, stage, treatment risk groups, presence of B symptoms and hematological parameters had no significant effect on overall and event-free survival in univariate analysis while bulky disease was the only significant factor on overall survival. Our treatment policy was succesful regarding the similar survival rates in the treatment risk groups, however novel treatment strategies adopting the early response with the reduction of adverse effects are planned in the near future.

    Introduction. We performed a review of the literature to elucidate the potential prognostic significance of serum vascular endothelial growth factor (sVEGF) levels in ovarian cancer. Methods. Eligible studies in English and Italian were identified in MEDLINE/PubMed from VEGF discovery to October 2011. All studies evaluating: (i) sVEGF levels before any surgical and chemotherapeutic treatment; (ii) the association between sVEGF levels and the established prognostic variables; (iii) the value of sVEGF levels in predicting patients' outcomes, were selected for this review. Results. The search resulted in 758 titles. Nine studies met the inclusion criteria. A statistically significant association between the level of sVEGF and FIGO stage, tumour grade, residual tumour size, lymph node involvement, and presence of ascites was found in at least one study. sVEGF, in comparison with the established prognostic factors, appears to be the best prognostic marker for overall survival, since it stands out as an independent prognostic factor in most of the studies considered. Moreover, sVEGF levels were shown to be independent prognostic factors by 2 out of the 3 studies that considered DFS as an end point. Conclusion. High levels of sVEGF identify a subgroup of patients with higher risk of death and/or recurrence. These patients should be eligible for individually tailored therapeutic interventions. PMID:22792477

  5. Methylator phenotype in colorectal cancer: A prognostic factor or not?

    2016-03-01

    Colorectal cancer (CRC) is due to different types of genetic alterations that are translated into different phenotypes. Among them, CpG island methylator phenotype (CIMP+) is the most recently involved in carcinogenesis of some CRC. The malignant transformation in this case is mainly due to the transcriptional inactivation of tumor suppressor genes. CIMP+ are reported to be more frequently found in the elderly and in women. The tumors are more frequently located in the proximal part of the colon, BRAF mutated and are associated with microsatellite instability (MSI) phenotype. All sporadic MSI CRC belong to the methylator phenotype, however some non MSI CRC may also harbor a methylator phenotype. The prognostic value of CIMP is not well known. Most studies show a worse prognosis in CIMP+ CRC, and adjuvant treatments seem to be more efficient. We review here the current knowledge on prognostic and predictive values in CIMP+ CRC.

    Background and Purpose Childhood absence epilepsy (CAE) is one of the most common types of pediatric epilepsy. It is generally treated with ethosuximide (ESM), valproic acid (VPA), or lamotrigine (LTG), but the efficacy and adverse effects of these drugs remain controversial. This study compared initial therapy treatment outcomes, including VPA-LTG combination, and assessed clinical factors that may predict treatment response and prognosis. Methods Sixty-seven patients with typical CAE were retrospectively enrolled at the Korea University Medical Center. We reviewed patients' clinical characteristics, including age of seizure onset, seizure-free interval, duration of seizure-free period, freedom from treatment failure, breakthrough seizures frequency, and electroencephalogram (EEG) findings. Results The age at seizure onset was 7.9±2.7 years (mean±SD), and follow-up duration was 4.4±3.7 years. Initially, 22 children were treated with ESM (32.8%), 23 with VPA (34.3%), 14 with LTG (20.9%), and 8 with VPA-LTG combination (11.9%). After 48 months of therapy, the rate of freedom from treatment failure was significantly higher for the VPA-LTG combination therapy than in the three monotherapy groups (p=0.012). The treatment dose administrated in the VPA-LTG combination group was less than that in the VPA and LTG monotherapy groups. The shorter interval to loss of 3-Hz spike-and-wave complexes and the presence of occipital intermittent rhythmic delta activity on EEG were significant factors predicting good treatment response. Conclusions This study showed that low-dose VPA-LTG combination therapy has a good efficacy and fewer side effects than other treatments, and it should thus be considered as a firstline therapy in absence epilepsy.

    Identify prognostic factors for survival and patterns of treatment failure after definitive radiochemotherapy for esophageal cancer. Between 2003 and 2006, 143 patients with squamous cell carcinoma and adenocarcinoma of the esophagus were retrospectively reviewed. Median age was 65 years (42-81). Median radiation dose was 62.5 Gy (38-72) with 1.8-2 Gy fraction. Median follow-up was 20.8 months (2.8-92.4). Three and 5-year local recurrence-free survival rates were 58.3% and 50.9%. In univariate analysis, traversable esophageal stricture was a prognostic factor. Three, 5-year locoregional recurrence-free survival rates were 42.4% and 34.9%. In multivariate analysis, traversable esophageal stricture and stage < IIB were independent prognostic factors. Three and 5-year disease-free survival rates were 30.5% and 25.9%. In multivariate analysis, Nutritional Risk Index (NRI) ≥ 97.5 and performance status (PS) = 0 were independent prognostic factors. Median, 3, and 5-year overall survival rates were 22.1 months, 34.4%, and 19.8%. In multivariate analysis, independent prognostic factors were NRI ≥ 97.5 and PS = 0. Median survival times for the NRI classes (no denutrition, moderate and severe denutrition) were 29.5, 19.7, and 12 months (P = 0.0004), respectively. A major impact of baseline NRI was found in terms of survival; it should be included in future prospective trials.

    OBJECTIVE Survival rates and prognostic factors for supratentorial hemispheric ependymomas have not been determined. The authors therefore designed a retrospective study to determine progression-free survival (PFS), overall survival (OS), and prognostic factors for hemispheric ependymomas. METHODS The study population consisted of 8 patients from our institution and 101 patients from the literature with disaggregated survival information (n = 109). Patient age, sex, tumor side, tumor location, extent of resection (EOR), tumor grade, postoperative chemotherapy, radiation, time to recurrence, and survival were recorded. Kaplan-Meier survival analyses and Cox proportional hazard models were completed to determine survival rates and prognostic factors. RESULTS Anaplastic histology/WHO Grade III tumors were identified in 62% of cases and correlated with older age. Three-, 5-, and 10-year PFS rates were 57%, 51%, and 42%, respectively. Three-, 5-, and 10-year OS rates were 77%, 71%, and 58%, respectively. EOR and tumor grade were identified on both Kaplan-Meier log-rank testing and univariate Cox proportional hazard models as prognostic for PFS and OS. Both EOR and tumor grade remained prognostic on multivariate analysis. Subtotal resection (STR) predicted a worse PFS (hazard ratio [HR] 4.764, p = 0.001) and OS (HR 4.216, p = 0.008). Subgroup survival analysis of patients with STR demonstrated a 5- and 10-year OS of 28% and 0%, respectively. WHO Grade III tumors also had worse PFS (HR 10.2, p = 0.004) and OS (HR 9.1, p = 0.035). Patients with WHO Grade III tumors demonstrated 5- and 10-year OS of 61% and 46%, respectively. Postoperative radiation was not prognostic for PFS or OS. CONCLUSIONS A high incidence of anaplastic histology was found in hemispheric ependymomas and was associated with older age. EOR and tumor grade were prognostic factors for PFS and OS on multivariate analysis. STR or WHO Grade III pathology, or both, predicted worse overall prognosis in patients

    Purpose This study aimed to identify time-dependent prognostic factors and demonstrate the time-dependent effects of important prognostic factors in patients with advanced gastric cancer (AGC). Materials and Methods We retrospectively evaluated 3,653 patients with AGC who underwent curative standard gastrectomy between 1991 and 2005 at the Korea Cancer Center Hospital. Multivariate survival analysis with Cox proportional hazards regression was used in the analysis. A non-proportionality test based on the Schoenfeld residuals (also known as partial residuals) was performed, and scaled Schoenfeld residuals were plotted over time for each covariate. Results The multivariate analysis revealed that sex, depth of invasion, metastatic lymph node (LN) ratio, tumor size, and chemotherapy were time-dependent covariates violating the proportional hazards assumption. The prognostic effects (i.e., log of hazard ratio [LHR]) of the time-dependent covariates changed over time during follow-up, and the effects generally diminished with low slope (e.g., depth of invasion and tumor size), with gentle slope (e.g., metastatic LN ratio), or with steep slope (e.g., chemotherapy). Meanwhile, the LHR functions of some covariates (e.g., sex) crossed the zero reference line from positive (i.e., bad prognosis) to negative (i.e., good prognosis). Conclusions The time-dependent effects of the prognostic factors of AGC are clearly demonstrated in this study. We can suggest that time-dependent effects are not an uncommon phenomenon among prognostic factors of AGC. PMID:26819803

    The introduction of molecular-targeted therapy has made dramatical changes to treatment for metastatic renal cell carcinoma. Currently, there are four vascular endothelial growth factor receptor-tyrosine kinase inhibitors and two mammalian target of rapamycin inhibitors in Japan. For the appropriate clinical use of these molecular-targeted drugs, the identification of prognostic and/or predictive factors in patients who received these drugs is required. Although molecular biological and genetic factors that determine the prognosis of patients with metastatic renal cell carcinoma have been reported, most of these factors are problematic in that the number of patients analyzed was small. In contrast, clinicopathological prognostic factors, including the practice of cytoreductive nephrectomy, pathological findings, metastatic sites and metastasectomy, and abnormal inflammatory response, have been identified by analyzing a relatively large number of patients. Several prognostic classification models that were developed by combining these clinicopathological factors are widely used in not only clinical trials, but also routine clinical practice. However, the quality of these prognostic models is considered to be insufficient regarding prognostic prediction of metastatic renal cell carcinoma patients and, thus, requires further improvements. Recently, basic and clinical studies have been extensively carried out for the identification of promising informative markers and for understanding molecular mechanisms of resistance to molecular-targeted drugs in metastatic renal cell carcinoma patients. The present review considers ongoing translational research efforts on clinicopathological, molecular biological, and genetic prognostic and/or predictive factors for metastatic renal cell carcinoma patients in the era of molecular-targeted therapy, and discusses the clinical implications of these findings.

    Peritoneal carcinomatosis (PC) of gastric origin is currently recognized as a terminal disease with a poor prognosis. Advancements in novel therapeutic approaches, including intraperitoneal chemotherapy (IPC), have recently been made and it is believed that this may have contributed to the improved survival observed in patients with PC. The present study aimed to investigate overall survival (OS) and the associated prognostic factors in patients with PC of gastric origin who underwent IPC. A total of 57 patients were studied, with a median age of 51 years. The median follow-up time was 12.4 months. PC was diagnosed in all patients with gastric cancer. The median survival time of all patients was 10.1 months, whilst the OS rate at 1, 2 and 3 years was observed to be 46, 19 and 12%, respectively. Symptomatic ascites and a signet ring cell (SRC) histopathological type were demonstrated to signify a poor prognosis. Complete resection of all gross disease (CCR-0) and an increased number of cycles of systemic chemotherapy were independent factors that were observed to correlate with increased OS. The most common morbidities of grade 3/4 adverse effects were bone marrow suppression, nausea or vomiting, and diarrhea. In conclusion, IPC is an important treatment option for patients with PC that has originated from gastric cancer. Symptomatic ascites and SRC adenocarcinoma serve as negative clinicopathological prognostic factors, whilst CCR-0 and increased systemic chemotherapy cycles (≥4 cycles) may prove to be an important therapeutic option for PC patients.

    OBJECTIVE: To determine the strength of the association between antenatal psychosocial risk factors and adverse postpartum outcomes in the family, such as assault of women by their partner, child abuse, postpartum depression, marital dysfunction and physical illness. DATA SOURCES: MEDLINE, Cinahl, Famli, Psych Abstracts and the Oxford Database of Perinatal Trials were searched from relevant articles published from Jan. 1, 1980, to Dec. 31, 1993, with the use of MeSH terms "depression, involutional," "child abuse," "child neglect," "domestic violence," "family," "marital adjustment," "family health," "newborn health," "child health," "physical illness," "social support," "psychosocial risk," "prediction," "risk factors," "obstetrics" and "prenatal care." Further articles were identified from bibliographies. STUDY SELECTION: Of the 370 articles identified through the search, 118 were included for review. Studies were included if they examined the association between psychosocial risk factors and the outcomes of interest. Articles were excluded if they were reviews of poor quality or they had one or more of the following features: insufficient description of the sample, a high attrition rate, a lack of standardized outcome measures, outcomes other than the ones of interest or results that had already been reported in a previous study. DATA EXTRACTION: The strength of evidence of each study was evaluated. On the basis of the evidence, each risk factor was assigned a rating of the strength of its association with each of the postpartum outcomes. The ratings were class A (good evidence of association), class B (fair evidence) and class C (no clear evidence). Of the 129 antenatal psychosocial risk factors studied, 15 were found to have a class A association with at least one of the postpartum outcomes. DATA SYNTHESIS: Child abuse and abuse of the mother by her partner were most strongly correlated (class A evidence) with a history of lack of social support, recent life

    Purpose: Head-and-neck squamous cell carcinoma (HNSCC) represents a heterogeneous group of patients in terms of subsite, treatment, and biology. Currently most management decisions are based on clinical parameters with little appreciation of patient differences in underlying tumor biology. We investigated the prognostic significance of clinicopathologic features and tumor hypoxia-inducible factor-1{alpha} (HIF-1{alpha}) expression in a homogeneous series of patients who underwent radiotherapy. Methods and Materials: An audit identified 133 consecutive patients with histologically proven squamous cell carcinoma of the tonsil or tongue base. All patients received primary radiotherapy between 1996 and 2001. Tumor HIF-1{alpha} expression was examined in 79 patients. Results: Features associated with poor locoregional control were low Hb level (p = 0.05) and advancing T (p = 0.008), N (p = 0.03), and disease (p = 0.008) stage. HIF-1{alpha} expression was a more significant adverse prognostic factor in the tonsil (hazard ratio [HR], 23.1; 95% confidence interval [CI]. 3.04-176.7) than the tongue-base tumor (HR, 2.86; 95% CI, 1.14-7.19) group (p = 0.03, test for interaction). High tumor HIF-1{alpha} expression was associated with low blood Hb levels (p = 0.03). In a multivariate analysis HIF-1{alpha} expression retained prognostic significance for locoregional control (HR, 7.10; 95% CI, 3.07-16.43) and cancer-specific survival (HR, 9.19; 95% CI, 3.90-21.6). Conclusions: There are significant differences in radiation therapy outcome within a homogeneous subsite of the oropharynx related to molecular marker expression. The work highlights the importance of studying homogeneous groups of patients in HNSCC, and the complex interrelationships between tumor biology and clinicopathologic factors. The establishment of tumor-type specific markers would represent a major advance in this area.

    Purpose/Objective(s): The aim of this study was to analyze the accuracy of gross tumor volume (GTV) delineation and clinical target volume (CTV) margins for neoadjuvant chemoradiation therapy (neo-CRT) in esophageal carcinoma at pathologic examination and to determine the impact on survival. Methods and Materials: The study population consisted of 63 esophageal cancer patients treated with neo-CRT. GTV and CTV borders were demarcated in situ during surgery on the esophagus, using anatomical reference points to provide accurate information regarding tumor location at pathologic evaluation. To identify prognostic factors for disease-free survival (DFS) and overall survival (OS), a Cox regression analysis was performed. Results: After resection, macroscopic residual tumor was found outside the GTV in 7 patients (11%). Microscopic residual tumor was located outside the CTV in 9 patients (14%). The median follow-up was 15.6 months. With multivariate analysis, only microscopic tumor outside the CTV (hazard ratio [HR], 4.96; 95% confidence interval [CI], 1.03-15.36), and perineural growth (HR, 5.77; 95% CI, 1.27-26.13) were identified as independent prognostic factors for OS. The 1-year OS was 20% for patients with tumor outside the CTV and 86% for those without (P<.01). For DFS, microscopic tumor outside the CTV (HR, 5.92; 95% CI, 1.89-18.54) and ypN+ (HR, 3.36; 95% CI, 1.33-8.48) were identified as independent adverse prognostic factors. The 1-year DFS was 23% versus 77% for patients with or without tumor outside the CTV (P<.01). Conclusions: Microscopic tumor outside the CTV is associated with markedly worse OS after neo-CRT. This may either stress the importance of accurate tumor delineation or reflect aggressive tumor behavior requiring new adjuvant treatment modalities.

    While the majority of children and adolescents with newly diagnosed childhood acute lymphoblastic leukemia (ALL) will be cured, as many as 20 % of patients will experience relapse. On current treatment regimens, the intensity of upfront treatment is stratified based upon prognostic factors with the aim of improving cure rates (for those at the highest risk of relapse) and minimizing treatment-related morbidity (for lower-risk patients). Here we review advances in the understanding of prognostic factors and their application. We also highlight novel treatment approaches aimed at improving outcomes in childhood ALL.

    Background Diabetic ketoacidosis (DKA) is characterized by a biochemical triad of hyperglycemia, acidosis, and ketonemia. This condition is life-threatening despite improvements in diabetic care. The purpose of this study was to evaluate the clinical and biochemical prognostic markers of DKA. We assessed correlations in prognostic markers with DKA-associated morbidity and mortality. Methods Two hundred and seventy patients that were hospitalized with DKA over a period of 2 years were evaluated clinically and by laboratory tests. Serial assays of serum electrolytes, glucose, and blood pH were performed, and clinical outcome was noted as either discharged to home or death. Results The analysis indicated that significant predictors included sex, history of type 1 diabetes mellitus or type 2 diabetes mellitus, systolic blood pressure, diastolic blood pressure, total leukocyte count, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, blood urea nitrogen, serum creatinine, serum magnesium, serum phosphate, serum osmolality, serum glutamic oxaloacetic transaminases, serum glutamic pyruvic transaminases, serum albumin, which were further regressed and subjected to multivariate logistic regression (MLR) analysis. The MLR analysis indicated that males were 7.93 times more likely to have favorable outcome compared with female patients (odds ratio, 7.93; 95% confidence interval, 3.99 to 13.51), while decreases in mean APACHE II score (14.83) and serum phosphate (4.38) at presentation may lead to 2.86- and 2.71-fold better outcomes, respectively, compared with higher levels (APACHE II score, 25.00; serum phosphate, 6.04). Conclusion Sex, baseline biochemical parameters such as APACHE II score, and phosphate level were important predictors of the DKA-associated mortality. PMID:27586452

    Backgrounds/Aims In hepatocellular carcinoma (HCC), bile duct invasion occurs far more rarely than vascular invasion and is not well characterized. In addition, the pathologic finding of bile duct invasion is not considered an independent prognostic factor for HCC following surgery. In this study, we determined the characteristics of HCC with bile duct invasion, and assessed the clinical significance of bile duct invasion. Methods We retrospectively reviewed the medical records of 363 patients who underwent hepatic resection for HCC at Seoul National University Hospital (SNUH) from January 2009 to December 2011. Preoperative, operative, and pathological data were collected. The risk factors for recurrence and survival were analyzed. Subsequently, the patients were divided into 2 groups according to disease stage (American Joint Committee on Cancer/International Union Against Cancer 7th edition): early stage (T1 and 2) and advanced stage (T3 and 4) group; and risk factors in the sub-groups were analyzed. Results Among 363 patients, 13 showed bile duct invasion on pathology. Patients with bile duct invasion had higher preoperative total bilirubin levels, greater microvascular invasion, and a higher death rate than those without bile duct invasion. In multivariate analysis, bile duct invasion was not an independent prognostic factor for survival for the entire cohort, but, was an independent prognostic factor for early stage. Conclusions Bile duct invasion accompanied microvascular invasion in most cases, and could be used as an independent prognostic factor for survival especially in early stage HCC (T1 and T2).

    A series of 256 consecutive cases of invasive primary conjunctival malignant melanomas was examined to identify clinical and histopathological prognostic factors. The follow up period varied between 0.3 and 45.9 years (mean 9 years, median 6.3 years). The 5 year survival rate was estimated at 82.9%, the 10 year survival rate at 69.3%. Multiple regression analysis with the Cox proportional hazards model was used to assess sex, age, and a number of baseline features of conjunctival malignant melanoma as possible prognostic factors influencing melanoma related mortality. In assessing each potential prognostic factor, the effects of all other factors were taken into account in the modelling process. Tumours in unfavourable locations--that is, those involving the palpebral conjunctiva, fornices, plica, caruncle, and lid margins, were associated with 2.2 times higher mortality compared with (epi)bulbar melanomas. Patients with mixed cell type tumours had about three times higher mortality compared with those with pure spindle cell melanomas, and histological evidence of lymphatic invasion by tumour cells was also a prognostic feature, carrying a fourfold increase in the death rate. Multifocal tumours were associated with a fivefold increase in mortality among those with tumours in favourable (epi)bulbar locations, but were not prognostic in patients with melanomas in unfavourable sites. The death rate was significantly higher in those with initial tumour thickness of more than 4 mm, but only among patients with unfavourably located melanomas. Sex, age, and clinical origin of the tumour (primary acquired melanosis, pre-existing naevus, or de novo) were not useful prognostic indicators in this study. PMID:8199108

    Almost one million new cases of gastric cancer were estimated to have occurred in 2012, making it the fifth most common malignancy in the world. It is also the third leading cause of cancer death of people of both genders worldwide. The aim of this study is to evaluate the significance of some prognostic factors for gastric cancer survival in 155 patients treated at Aleksandrovska University Hospital, Sofia, Bulgaria. This retrospective study includes patients diagnosed and treated at Department of Surgery of Aleksandrovska University Hospital for the 9-years period of time between January 2005 and December 2013. We classified the prognostic factors as patient-related (age at diagnosis specification, gender, and blood type), tumor-related (N-stage, tumor differentiation, process localization), and treatment related (patients who had radical surgery and adjuvant therapy). We found that blood type is the only statistically significant prognostic factor for overall survival from the patients-related group of factors (p = 0.030). The only prognostic factor from the ones in the tumor related group remains the N-stage according to the TNM classification (p = 0.003). Adjuvant could not prove its value for overall survival (p = 0.675).

    Mycosis fungoides is the most prevalent form of primary cutaneous T-cell lymphoma. Patients frequently present with early-stage disease typically associated with a favourable prognosis and survival of 10-35 years, but over 25% may progress to advanced disease with a median survival < 4 years, and just 13 months in those with nodal involvement. Sézary syndrome presents in advanced disease with erythroderma, blood involvement and lymphadenopathy. The Bunn and Lamberg staging system (1979) includes stages IA-IIA (early-stage disease) and IIB-IVB (advanced-stage disease) and provides prognostic information, but some patients with tumour-stage disease (IIB) have a worse prognosis than those with erythrodermic-stage (III). Conversely, patients with plaque-stage (IB) folliculotropic mycosis fungoides may have a worse outcome than those with tumour-stage (IIB). The more recent staging system of the European Organisation for the Research and Treatment of Cancer/International Society for Cutaneous Lymphoma has been designed to reflect tumour burden at different sites. However, this staging system has not been validated prospectively for prognosis. Furthermore, this staging system does not include a detailed measurement of skin tumour burden, as indicated by the modified skin weighted severity assessment tool. This assessment measures body surface area of disease and is weighted to record patch, plaque and tumour to produce a numerical value from 0·5 to 400 and is an established endpoint for clinical studies. Nor does this staging include clinicopathological features associated with a poor prognosis such as folliculotropism. Here we review the clinical, haematological, pathological and genotypic parameters outside the staging system, which may affect survival in mycosis fungoides and Sézary syndrome. Most studies are retrospective and single centre. The identification of poor prognostic factors may be used to develop a prognostic index to use alongside staging, which

    Background: Prediction of negative postoperative outcomes after long-bone fracture treatment may help to optimize patient care. We recently completed the Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT), a large, multicenter trial of reamed and unreamed intramedullary nailing of tibial shaft fractures in 1226 patients. Using the SPRINT data, we conducted an investigation of baseline and surgical factors to determine any associations with an increased risk of adverse events within one year of intramedullary nailing. Methods: Using multivariable logistic regression analysis, we investigated fifteen baseline and surgical factors for any associations with an increased risk of negative outcomes. Results: There was an increased risk of negative events in patients with a high-energy mechanism of injury (odds ratio [OR] = 1.57; 95% confidence interval [CI], 1.05 to 2.35), a stainless steel compared with a titanium nail (OR = 1.52; 95% CI, 1.10 to 2.13), a fracture gap (OR = 2.40; 95% CI, 1.47 to 3.94), and full weight-bearing status after surgery (OR = 1.63; 95% CI, 1.00 to 2.64). There was no increased risk with the use of nonsteroidal anti-inflammatory agents, late or early time to surgery, or smoking status. Open fractures had a higher risk of events among patients treated with reamed nailing (OR = 3.26; 95% CI, 2.01 to 5.28) but not in patients treated with unreamed nailing (OR = 1.50; 95% CI, 0.92 to 2.47). Patients with open fractures who had wound management either without any additional procedures or with delayed primary closure had a decreased risk of events compared with patients who required subsequent, more complex reconstruction (OR = 0.18 [95% CI, 0.09 to 0.35] and 0.29 [95% CI, 0.14 to 0.62], respectively). Conclusions: We identified several baseline fracture and surgical characteristics that may increase the risk of adverse events in patients with tibial shaft fractures. Surgeons should consider the

    A variety of prognostic factor models to predict survival in patients with metastatic renal cell carcinoma have been developed. Diverse populations of patients with variable treatments have been used for these analyses. A variety of clinical, pathologic, and molecular factors have been studied, but current models use predominantly easily obtained clinical factors. These approaches are reviewed, and current approaches to further refine and develop these techniques are reviewed.

    Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous drug reaction. Although the severity-of-illness score (SCORTEN) has been proposed for toxic epidermal necrolysis (TEN) for 10 years, a prognostic score for DRESS is still lacking. To identify prognostic factors of DRESS patients during hospitalization in one medical health system in Taiwan. We retrospectively reviewed all patients with DRESS diagnosed by dermatologists in Chang Gung Memorial Hospital (CMGH) Health System from 2001 to 2010. To study prognostic factors, we collected data at early disease and maximal disease stages. 91 individuals, including 13 dead patients, were evaluated. Five independent prognostic factors of death were found: heart rate > 90/min, white blood cells >12,000/mm(3) and respiratory rate >20/min (at early disease stage), coagulopathy and gastrointestinal bleeding (at maximal disease stage). In addition, systemic inflammatory response syndrome (SIRS) occurred at a much higher percentage among non-survivors throughout hospitalization. We found tachycardia, leukocytosis, tachypnea, coagulopathy, gastrointestinal bleeding and SIRS were associated with a poor outcome in DRESS patients. DRESS patients with persistent SIRS during hospitalization were also associated with a higher mortality risk. Early recognition and prompt intervention in these factors may improve outcome.

    The purpose of this study is to determine prognostic factors in patients with high-grade recurrent glioma for 3 outcome variables (overall survival, progression-free survival [PFS], and PFS rate 6 months after study registration [PFS6]). Data from 15 North Central Cancer Treatment Group (NCCTG) trials (n = 469, 1980–2004) and 12 North American Brain Tumor Consortium (NABTC) trials (n = 596, 1998–2002) were included. Eighteen prognostic variables were considered including type of treatment center (community/academic) and initial low-grade histology (yes/no). Recursive partitioning analysis (RPA), Cox proportional hazards, and logistic regression models with bootstrap resampling were used to identify prognostic variables. Longer survival was associated with last known grade (Grade) of III, younger age, ECOG performance score (PS) of 0, shorter time from initial diagnosis (DxTime), and no baseline steroid use. Factors associated with longer PFS were Grade III and shorter DxTime. For patients without temozolomide as part of the treatment regimen, the only factor associated with better PFS6 was Grade III, although DxTime was important in RPA and PS was important in logistic regression. Grade was the most important prognostic factor for all three endpoints regardless of the statistical method used. Other important variables for one or more endpoints included age, PS, and DxTime. Neither type of treatment center nor initial low-grade histology was identified as a major predictor for any endpoint. PMID:20150383

    Purpose: Non-small cell lung cancers (NSCLCs) with pathologically documented ipsilateral mediastinal lymph node (LN) metastases (pN2) are a broad spectrum of diseases. We retrospectively analyzed prognostic factors for cases of pN2 NSCLC treated by surgical resection. Methods: Clinicopathological data were reviewed for consecutive 121 patients who underwent anatomical pulmonary resection with mediastinal LN sampling or dissection for pN2 NSCLC over a 15-year period. Results: The 5-year survival rate for all patients was 29.9%. Clinical N status, curability, surgical procedure and adjuvant chemotherapy were favorable prognostic factors in univariate analysis, with 5-year survival rates of 35.0% for cN0/1 vs. 17.7% for cN2/3 cases; 33.1% for R0 vs. 14.7% for R1/2 resection; 31.5% for lobectomy vs. 25.0% for bilobectomy and 15.6% for pneumonectomy; and 72.7% with adjuvant chemotherapy vs. 23.8% without adjuvant chemotherapy. Survival did not differ significantly based on gender, age, smoking status, clinical T status, tumor location, histology, skip metastasis, subcarinal LN metastasis, or number of involved N2 levels. In multivariate analysis, adjuvant chemotherapy, R0 resection, and lobectomy emerged as independent favorable prognostic factors. Conclusion: Complete resection using lobectomy and adjuvant chemotherapy are favorable prognostic factors in cases of pN2 NSCLC. PMID:25641029

    Background Prognostic factors are associated with the risk of a subsequent outcome in people with a given disease or health condition. Meta-analysis using individual participant data (IPD), where the raw data are synthesised from multiple studies, has been championed as the gold-standard for synthesising prognostic factor studies. We assessed the feasibility and conduct of this approach. Methods A systematic review to identify published IPD meta-analyses of prognostic factors studies, followed by detailed assessment of a random sample of 20 articles published from 2006. Six of these 20 articles were from the IMPACT (International Mission for Prognosis and Analysis of Clinical Trials in traumatic brain injury) collaboration, for which additional information was also used from simultaneously published companion papers. Results Forty-eight published IPD meta-analyses of prognostic factors were identified up to March 2009. Only three were published before 2000 but thereafter a median of four articles exist per year, with traumatic brain injury the most active research field. Availability of IPD offered many advantages, such as checking modelling assumptions; analysing variables on their continuous scale with the possibility of assessing for non-linear relationships; and obtaining results adjusted for other variables. However, researchers also faced many challenges, such as large cost and time required to obtain and clean IPD; unavailable IPD for some studies; different sets of prognostic factors in each study; and variability in study methods of measurement. The IMPACT initiative is a leading example, and had generally strong design, methodological and statistical standards. Elsewhere, standards are not always as high and improvements in the conduct of IPD meta-analyses of prognostic factor studies are often needed; in particular, continuous variables are often categorised without reason; publication bias and availability bias are rarely examined; and important

    Because of the introduction of modern diagnostic methods, numerous prognostic and predictive factors have been recognized and are today considered classic, yet they seem to be insufficient in assessment of prognosis, hence the need for further investigations. Among factors newly discovered by molecular techniques, there are class I and II topoisomerases, the role of which as prognosticators has not been fully determined. The objective of the present investigation was the assessment of topoisomerase II alpha (TOP2A) expression in patients with infiltrating breast carcinoma, as a prognostic factor in correlation with other recognized prognosticators and patient survival. The study was carried out in 151 patients treated by mastectomy and lymph node excision followed by adjuvant chemotherapy. The material was evaluated histopathologically according to the pTNM system, taking into consideration such parameters as grade of malignancy (G); the ER, PR as well as HER2 and TOP2A receptors status--all of them were assessed immunohistochemically. TOP2A was expressed with varying intensity in the majority of infiltrating ductal carcinomas studied, more frequently in large T3 and T4, grade G2 and G3 tumours, in patients with extensive metastases to regional N2 and N3 lymph nodes, a positive HER2 and negative ER and PR status. Five-year mortality rates were higher and 5-year symptom-free survival rates were lower in patients with TOP2A-positive tumours as compared to individuals with a negative TOP2A status. The study indicates that TOP2A expression is a negative predictive factor and may be recognized as a prognostic factor.

    This study evaluated the relationship between pretreatment hemoglobin (Hb) and prognostic factors in Thai patients with endometrial cancer. Medical records of 228 patients who had undergone surgery between January 2005 and December 2007 were retrospectively reviewed. Associations between clinicopathological variables and pretreatment Hb levels were described using Pearson's chi square test or two-tailed Fisher's exact test. Survival analysis was performed with Kaplan-Meier estimates. Univariate and Cox-regression models were used to evaluate the prognostic impact of various factors, including Hb levels, in term of disease-free survival. The median duration of follow-up was 38.2 months. Eighty-nine patients (39%) had a preoperative Hb level of <12 g/dL, these having significantly higher rates of non-endometrioid histology, advanced FIGO stage, lymphovascular space invasion, cervical involvement, adnexal involvement, positive peritoneal cytology, and lymph node involvement than patients with Hb ≥12 g/dL. The 5-year disease-free and overall survival were significantly lower in patients with pretreatment Hb levels <12 g/dL compared with those with Hb ≥12 g/dL (79.3% vs. 89.2%, p=0.044 and 87.6% vs. 99.3%, p<0.001, respectively). In the multivariate analysis only histology, myometrial invasion, and lymphovascular invasion proved to be independent prognostic factors, whereas tumor grading, stage, cervical involvement, adnexal involvement, positive peritoneal cytology, lymph node involvement, and low Hb were not. In conclusion, presence of anemia before treatment may reflect poor prognostic factors in patients with endometrial cancer and low pretreatment hemoglobin level may have a prognostic impact on clinical outcome.

    Prostate cancer is the most common urologic neoplasm and the second leading cause of cancer-related death among men in many developed countries. Given the highly heterogeneous behaviour of the disease, there is a great need for prognostic factors, in order to stratify the clinical risk and give the best treatment options to the patient. Clinical factors, such as prostate-specific antigen value and derivatives, and pathological factors, such as stage and Gleason grading, are well kown prognostic factors. Nomograms can provide useful prediction in each clinical sceario. The field of molecular biomarkers is briskly evolving towards personalized medicine. TMPRSS2-ERG fusion, deletion of PTEN ed and gene panels are some of the more extensively explored molecular features in prostate cancer outcome prediction. In the near future, circulating tumour cells, exosomes and microRNAs could give us further, not invasive important tools.

    Dear Editor, Inhibition of the epidermal growth factor receptor (EGFR) is a new strategy in treatment of a variety of solid tumors, such as colorectal carcinoma, non-small cell lung cancer, squamous cell carcinoma of the head and neck, and pancreatic cancer (1). Cetuximab is a chimeric human-murine monoclonal antibody against EGFR. Cutaneous side effects are the most common adverse reactions occurring during epidermal growth factor receptor inhibitors (EGFRI) therapy. Papulopustular rash (acne like rash) develop with 80-86% patients receiving cetuximab, while xerosis, eczema, fissures, teleangiectasiae, hyperpigmentations, and nail and hair changes occur less frequently (2). The mechanism underlying these skin changes has not been established and understood. It seems EGFRI alter cell growth and differentiation, leading to impaired stratum corneum and cell apoptosis (3-5). An abdominoperineal resection of the rectal adenocarcinoma (Dukes C) was performed on a 43-year-old female patient. Following surgery, adjuvant chemo-radiotherapy was applied. After two years, the patient suffered a metastatic relapse. Abdominal lymphadenopathy was detected on multi-slice computer tomography (MSCT) images, with an increased value of the carcinoembryonic antigen (CEA) tumor marker (maximal value 57 ng/mL). Hematological and biochemical tests were within normal limits, so first-line chemotherapy with oxaliplatin and a 5-fluorouracil (FOLFOX4) protocol was introduced. A wild type of the KRAS gene was confirmed in tumor tissue (diagnostic prerequisite for the introduction of EGFRI) and cetuximab (250 mg per m2 of body surface) was added to the treatment protocol. The patient responded well to the treatment with confirmed partial regression of the tumor formations. Three months after the patient started using cetuximab, an anti-EGFR monoclonal antibody, the patient presented with a papulopustular eruption in the seborrhoeic areas (Figure 1) and eczematoid reactions on the extremities

    2011-01-01

    Background When present sciatica is considered an obstacle to recovery in low back pain patients, yet evidence is limited regarding prognostic factors for persistent disability in this patient group. The aim of this study is to describe and summarise the evidence regarding prognostic factors for sciatica in non-surgically treated cohorts. Understanding the prognostic factors in sciatica and their relative importance may allow the identification of patients with particular risk factors who might benefit from early or specific types of treatment in order to optimise outcome. Methods A systematic literature search was conducted using Medline, EMBASE and CINAHL electronic databases. Prospective cohort studies describing subjects with sciatica and measuring pain, disability or recovery outcomes were included. Studies of cohorts comprised entirely of surgically treated patients were excluded and mixed surgically and conservatively treated cohorts were included only if the results were analysed separately by treatment group or if the analysis was adjusted for treatment. Results Seven adequate or high quality eligible studies were identified. There were conflicting but mainly negative results regarding the influence of baseline pain severity, neurological deficit, nerve root tension signs, duration of symptoms and radiological findings on outcome. A number of factors including age, gender, smoking, previous history of sciatica and heaviness of work do not appear to influence outcome. In contrast to studies of low back pain and purely surgically treated sciatica cohorts, psychological factors were rarely investigated. Conclusions At present, the heterogeneity of the available studies makes it difficult to draw firm conclusions about sciatica prognosis, and highlights the need for further research for this group of patients. Large scale prospective studies of high methodological quality, using a well-defined, consistent definition of sciatica and investigating psychosocial

    The data on 914 patients enrolled in four randomised trials in advanced ovarian cancer, consecutively conducted by the same cooperative group between 1978 and 1986, were analysed with the aims of: (1) determining the impact of selected prognostic variables on survival; (2) finding, from the interaction of favourable prognostic factors and treatment, an approximate estimate of the magnitude of the survival advantage associated with the use of platinum-based combination chemotherapy. The overall 3-year survival in this series of patients is twice that reported historically (22%; 95% CL 18.7-25.4). The proportional hazard regression model was used to perform the analysis on survival. Residual tumour size, age, FIGO stage and cell type were all independent determinants of survival. Differences in survival from the various prognostic groups were impressive with 5-year survival rates ranging from 7 to 62%. However, these differences were not qualitative (i.e. the kinetics of survival were similar for the best and the worst groups) suggesting that current prognostic factors are of little use for selecting 'biologically' different sub-populations. Platinum-based regimens were associated to an overall prolonged median survival, but this benefit was not observable in the subgroup with most favourable prognosis (less than 2 cm residual tumour size). The implications of these observations for clinical research and ovarian cancer patients care are discussed.

    Lymphopenia is frequent in advanced cancers and predicts the toxicity of chemotherapy. Its impact on relapse and survival is uncertain. Its prognostic value for survival was analyzed in 3 databases of previously reported prospective multicenter studies: 1) FEC chemotherapy in metastatic breast carcinoma; 2) CYVADIC in advanced soft-tissue sarcoma (EORTC-STBSG 62791); 3) prospective, consecutive phase III studies of aggressive diffuse large-cell non-Hodgkin’s lymphomas conducted at Bérard center between 1987 and 1993. Univariate and multivariate analyses of prognostic factors for survival were performed. The incidence of lymphopenia <1000/μL before treatment was constant among series: 25%, 24%, 27% respectively. Lymphopenia was significantly more frequent (p<0.05) in metastatic breast cancer patients with performance status (PS)>1, non-Hodgkin’s lymphoma patients with international prognostic index (IPI)>0, and advanced soft-tissue sarcoma and metastatic breast cancer patients with bone metastases. In univariate analysis, lymphopenia <1000/μL significantly correlated to overall survival in patients with metastatic breast cancer (median 10 vs. 14 months, p <0.0001), advanced soft-tissue sarcoma (median 5 vs. 10 months, p <0.01), and non-Hodgkin lymphoma (median 11 vs. 94 months, p <0.0001). In multivariate analysis (Cox model), lymphopenia was an independent prognostic factor for overall survival in metastatic breast cancer (RR: 1.8; 95%CI 1.3–2.4) along with liver metastases and PS; in advanced soft-tissue sarcoma (RR: 1.46; 95%CI 1.0–2.1) along with liver metastases, lung metastases and PS; and in non-Hodgkin’s lymphoma (RR: 1.48; 95%CI 1.03–2.1) along with IPI. Our findings demonstrate that lymphopenia is an independent prognostic factor for overall and progression-free survival in several cancers. PMID:19549917

    Certain clinical conditions and markers have recently been demonstrated to modify the natural history of acromegaly in affected patients. Thus, some clinical, histological, radiological and molecular factors are associated with more aggressive pituitary tumors that have higher biochemical activity, higher tumor volumes and decreased tumoral and biochemical responses to current therapies. However, these factors do not seem to have an equal influence on the prognosis of patients with acromegaly. We present a review of the factors that influence the clinical course of patients with acromegaly and propose a risk value for each factor that will allow prognostic scoring for affected patients by considering a combination of these factors.

    Background Chordoma in the spine is relatively rare, and minimal information has been published in the literature regarding this subject. Moreover, there are controversies over prognostic factors of this disease. Methods A retrospective analysis of chordoma in the spine was performed by survival analysis. Local relapse-free survival (LRFS) and overall survival (OS) were analyzed from the date of surgery to the date of local recurrence and death. The LRFS and OS rates were estimated using the Kaplan–Meier method to identify potential prognostic factors. Factors with P values ≤ .1 were subjected to multivariate analysis by Cox regression analysis. P values ≤ .05 were considered statistically significant. Results A total of 153 patients with spinal chordoma were included in the study. The mean follow-up period was 72.0 months (range, 1–279 months). Local recurrence was detected in 51 cases after initial surgery in our center, while death occurred in 42 cases. The statistical analysis suggested that tumor location of C3–L5, dedifferentiated chordoma, preoperative Frankel scores A–C, and total spondylectomy were independent prognostic factors for LRFS. In addition, total en bloc spondylectomy and Karnofsky' performance status (KPS) ≥ 80% were favorable factors for OS. Conclusions Total spondylectomy, by either en bloc or piecemeal method, could significantly reduce LRFS for spinal chordoma. Location of C3–L5 is a favorable factor for LRFS, while dedifferentiated subtype and preoperative Frankel scores A–C are adverse prognostic factors. In addition, total en bloc spondylectomy and KPS ≥ 80% significantly improve overall survival of patients with spinal chordoma. PMID:25488908

    Radiotherapy has a not well-established role in the pre-operative and in the post-operative setting in gastric cancer (GC) patients. Randomized trials report controversial outcomes and impact on survival. In the D2 loco-regional node resection era, after a well-performed radical surgery, local treatment using radiotherapy combined to chemotherapy should be considered for locally advanced GC. Prognostic factors could help the better selection of subgroups that present high risk of loco-regional recurrence. Then, the addition of radiotherapy could improve the disease-free survival and also quality of life. There are no large prospective studies that have assessed specific factors predicting for recurrence or survival, but only retrospective series, some of them including high number of patients with homogeneous characteristics. In locally advanced GC adding radiotherapy to the post-operative chemotherapy seems to improve outcomes and quality of life. Prognostic factors such as T-stage, N-status, nodal ratio, and other histological factors should be considered to submit patients to post-operative combined treatment. Larger prospective series are necessary to investigate the role of combined chemoradiation after radical D2-resection, especially in locally advanced GC. Further prospective investigations are needed to suggest prognostic factors that have significant impact on survival and recurrence, improving the management and outcomes, particularly in locally advanced GC patients.

    In the context of customized patient care for upper tract urothelial carcinoma (UTUC), decision-making could be facilitated by risk assessment and prediction tools. The aim of this study was to provide a critical overview of existing predictive models and to review emerging promising prognostic factors for UTUC. A literature search of articles published in English from January 2000 to June 2016 was performed using PubMed. Studies on risk group stratification models and predictive tools in UTUC were selected, together with studies on predictive factors and biomarkers associated with advanced-stage UTUC and oncological outcomes after surgery. Various predictive tools have been described for advanced-stage UTUC assessment, disease recurrence and cancer-specific survival (CSS). Most of these models are based on well-established prognostic factors such as tumor stage, grade and lymph node (LN) metastasis, but some also integrate newly described prognostic factors and biomarkers. These new prediction tools seem to reach a high level of accuracy, but they lack external validation and decision-making analysis. The combinations of patient-, pathology- and surgery-related factors together with novel biomarkers have led to promising predictive tools for oncological outcomes in UTUC. However, external validation of these predictive models is a prerequisite before their introduction into daily practice. New models predicting response to therapy are urgently needed to allow accurate and safe individualized management in this heterogeneous disease. PMID:27785429

    The aim of the study was to evaluate VEGF expression in tumour biopsies as a prognostic factor for radiotherapy outcome in advanced carcinoma of the cervix. A retrospective study was carried out on 100 patients. Pre-treatment tumour VEGF expression was examined immunohistochemically in formalin-fixed, paraffin-embedded biopsies using a widely available commercial antibody. A semi-quantitative analysis was made using a scoring system of 0, 1, 2, and 3, for increasing intensity of staining. High VEGF expression was associated with a poor prognosis. A univariate log rank analysis found a significant relationship with overall survival (P = 0.0008) and metastasis-free survival (P = 0.0062), but not local control (P = 0.23). There was no correlation between VEGF expression and disease stage, tumour differentiation, patient age, or tumour radiosensitivity (SF2). In a Cox multivariate analysis of survival VEGF expression was the most significant independent prognostic factor (P = 0.001). After allowing for VEGF only SF2 was a significant prognostic factor (P = 0.003). In conclusion, immunohistochemical analysis of VEGF expression is a highly significant and independent prognostic indicator of overall and metastasis-free survival for patients treated with radiotherapy for advanced carcinoma of the cervix. It is also a rapid and easy method that could be used in the clinical setting, to identify patients at high risk of failure with conventional radiotherapy who may benefit from novel approaches or chemoradiotherapy. © 2000 Cancer Research Campaign PMID:10944602

    Kidney cancer, despite the constant upward trend in the incidence of this type of cancer (about 1.5-5.9% per year), is rather rare, representing approximately 2-3% of all adult cancers. Since recently, drugs based on so-called targeted therapy play a decisive role in the treatment of patients with metastatic kidney cancer. Prognostic and predictive factors can significantly contribute to prognosis assessment and the correct classification of patients to specific forms of causal treatment of kidney cancer. In addition to the most commonly used and widely known prognostic factors, grouped in the so-called Motzer model, new prognostic markers of this tumour are being sought. Preliminary reports indicate that there may be a promising role of factors that regulate the cell cycle and apoptosis, and agents from the group of hypoxia-induced proteins. The proliferation markers or proteins related to cellular adhesion can also be relevant. This article presents examples of markers from the first of the above groups of proteins, which on the basis of the performed analyses showed independent prognostic or predictive value in kidney cancer.

    Abstract Background: The plasma Epstein–Barr virus (EBV) DNA level in patients with nasopharyngeal carcinoma (NPC) performs as an appealing prognostic factor, but conclusions of its prognostic values from previous studies are inconsistent. In this study, we performed a comprehensive meta-analysis to evaluate the prognostic value of EBV DNA level in patients with NPC. Methods: Published studies were searched in PubMed. The baseline characteristics of patients, overall survival (OS), and other survival outcomes were extracted. Pooled hazard ratio (HR), 95% confidence interval (CI), and P value were calculated to estimate the prognostic value of EBV DNA level. Each cut-off value mentioned in the studies was obtained. Kaplan–Meier curves were used to extract data, and graphical survival plots were extracted for calculating HR when the study did not describe the information directly. Results: This meta-analysis pooled 23 eligible studies including 10,732 patients with NPC. The pooled HR (95% CI) of pretreatment plasma EBV DNA level (pre-DNA) for OS was 2.78 (2.19, 3.55), and the HR (95% CI) of posttreatment plasma EBV DNA level (post-DNA) for OS was 5.43 (2.72, 10.82), suggesting that EBV DNA level was significantly correlated to the outcomes of patients with NPC. Conclusion: High expression levels of EBV DNA predicts poor prognosis in NPC. PMID:27749596

    Background: Tongue cancer is one of the common cancers in head and neck region. Cervical node metastasis is the strongest poor prognostic factor. Other prognostic factors were also said to be of significance. Our aim was to find out the significant prognostic factors of tumor aggressiveness in Indian perspective. Material and Methods: Sixty cases of early cancer of oral tongue with clinically non palpable neck nodes were managed by upfront surgery. Surgeries performed for the primary tumor were ‘wide excision’ or ‘hemiglossectomy’ along with neck dissection. Patients were then given post-operative radiotherapy according to standard guidelines. They were analyzed using a detailed proforma. Three patients were lost to follow-up rest all patients were followed. Results: Recurrence was seen in 11 out of 60 patients (18.3%), in an average follow-up period of about 28 months. Among those who recurred, one patient had both nodal and local recurrence, 2 patients had nodal only (regional) recurrence and rest 8 patients had local recurrence. The prognostic factors that significantly affected the recurrence were endo-phytic disease, depth of invasion, lymphatic invasion, muscle invasion, healthy margin and adjuvant radiotherapy. Conclusion: The risk factors for recurrence in early lesions of oral tongue are - Cervical nodal metastasis, Lymphatic permeation, Depth of disease - 6 mm or more, poorly differentiated tumor, Endophytic (infiltrative) disease, Young age at presentation and Muscle invasion. In early tongue lesions, that are node negative, selective node dissection (SND) including level 1, 2, 3 and 4, is a viable option for neck to decrease the morbidity of MND. PMID:24392400

    Pathologists' contribution in the determination of prognosis in invasive penile squamous cell carcinoma is crucial. The TNM staging system is based on the identification of pathological data. There are multiple pathologically based factors believed to be important in relation to the rates of regional inguinal lymph node and specific cancer death. Among them are tumor site, size, histological subtypes, thickness or anatomical level of invasion, tumor front, and vascular or perineural invasion. The identification of these factors determines the prognostic profile of patients with penile cancer. These factors are used for the construction of pathological risk groups, prognostic index, or nomograms and are helpful in the prediction of nodal metastasis or patients' outcome. This review will describe in detail the influential pathological prognostic factors present in each tumor category emphasizing the impact of especial histological subtypes in tumor spread and final outcome. There are few studies comprehensibly addressing the relation of tumor morphology and prognosis according to histological types. We are summarizing findings of prognostic factors in 3 different series for the most common types and individual series in more recently described tumor entities. We had found a broad correlation of special subtypes of penile squamous cell carcinomas that made regional nodal status and final outcome predictable according to histological features of the tumor. These findings permitted grouping special subtypes of squamous cell carcinomas into prognosis risk groups of low, intermediate, and high. In the first category of excellent prognoses are the usual grade I, verrucous, papillary NOS, pseudohyperplastic and cuniculatum carcinomas. In the second group, there are the grade II usual, mixed and warty carcinomas. The third category of tumors, with the worst prognosis is composed of high grade usual, basaloid, warty-basaloid, papillary basaloid, and sarcomatoid carcinomas. We

    Objective: To evaluate the factors that influence the survival rate of replantation and revascularization of the thumb and/or fingers. Methods: We included fifty cases treated in our department from May 2012 to October 2013 with total or partial finger amputations, which had blood perfusion deficit and underwent vascular anastomosis. The parameters evaluated were: age, gender, comorbidities, trauma, time and type of ischemia, mechanism, the injured area, number of anastomosed vessels and use of vein grafts. The results were statistically analyzed and type I error value was set at p <0.05 . Results: Fifty four percent of the 50 performed replantation survived. Of 15 revascularizations performed, the survival rate was 93.3%. The only factor that affected the survival of the amputated limb was the necessity of venous anastomosis. Conclusion: We could not establish contraindications or absolute indications for the replantation and revascularization of finger amputations in this study. Level of Evidence III, Retropective Study.

    This study retrospectively collected the clinical and laboratory data of 114 patients with Castleman disease (CD) from a single medical centre. Clinical classification identified 62 patients (54·4%) with unicentric Castleman disease and 52 (45·6%) with multi-centric Castleman disease. Pathological classification revealed 68 cases (59·6%) of hyaline vascular variant, 16 (14·1%) mixed cellular variant (Mix) and 30 (26·3%) plasmacytic variant. Clinical complications occurred in 69 CD patients, including 37 cases of paraneoplastic pemphigus (PNP) and 25 cases with renal complications. Haematological involvement, pleural effusion and/or ascites and POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes) were also found. Univariate analysis showed that presence of clinical complications and PNP were both risk factors relating to CD patient survival. Prognostic factors showing P < 0·15 in univariate analysis and those with clinical significance were subjected to multivariate analysis using a Cox regression model. PNP presence and age over 40 years both significantly adversely affected survival. Thus, only presence of PNP was identified as an independent unfavourable survival risk factor in both univariate and multivariate analyses. Overall, the present data provide a panoramic description of CD cases and emphasize that the presence of PNP is an adverse prognostic factor.

    Introducción: La pielonefritis enfisematosa es una infección grave del tracto urinario caracterizada por la presencia de gas en los sistemas colectores, en el parénquima renal o en el tejido perirrenal; su causa no es del todo conocida, pero se ha sugerido que se debe a la fermentación de glucosa por enterobacterias y anaerobios. El objetivo fue evaluar los factores pronósticos de morbimortalidad en pacientes con diagnóstico de pielonefritis enfisematosa. Métodos: estudio de cohorte histórica en pacientes con diagnóstico de pielonefritis enfisematosa que ingresaron a nuestro hospital de marzo de 2005 a diciembre de 2014. Se identificaron los pacientes con desenlace adverso definido como aquel que requirió estancia en unidad de cuidados intensivos, nefrectomía o muerte. Se realizó una regresión logística múltiple para obtener la relación de cada factor pronóstico con el desenlace adverso. Resultados: Fueron evaluados 73 pacientes (48 mujeres [65.8 %]). Diabetes, litiasis urinaria, infección por Escherichia coli y el estado de choque se presentaron en 68.5 %, 68.5 %, 63 % y 15.1 %, respectivamente. Fueron factores significativos para desenlace adverso la leucocitosis ≥ 12 000 μL (RM 43.65, IC 95 % 2.36-805, p < 0.001), la trombocitopenia ≤ 120 000 μL (RM 363, IC 95 % 9.2-14208, p < 0.0001), y la clase radiológica 3 de Huang (RM 62, IC 95 % 4-964, p < 0.001). Conclusión: la trombocitopenia, la leucocitosis y la clase radiológica 3 se asociaron con un desenlace adverso en los pacientes con pielonefritis enfisematosa.

    Introdução: A ressecção de metástases hepáticas é o único tratamento potencialmente curativo em doentes com metástases hepáticas de cancro colo-rectal, resultando numa sobrevida global de 36-58%. Até à data foram publicados múltiplos trabalhos sobre factores de prognóstico após hepatectomia em doentes com metástases hepáticas de cancro colo-rectal. No entanto, poucos apresentaram modelos de prognóstico que permitam estratificar os doentes em grupos de risco, relacionando-os com sobrevida após metastasectomia hepática.Objectivos: Identificar, avaliar e comparar os diferentes scores de prognóstico após recessão de metástases hepáticas de cancro colo-rectal.Material e Métodos: Pesquisa na PubMed, Cochrane e Embase, de artigos publicados entre 1990 e 2013, usando os termos ‘recessão hepática’, ‘cancro colo-rectal’, ‘metástases hepáticas’, ‘hepatectomia’, ‘prognóstico’ e ‘modelo’. Apenas os artigos que apresentaram modelos de prognóstico com base em variáveis clínico-patológicas foram incluídos.Resultados: De 1996 a Junho de 2013, 19 modelos de prognóstico foram identificados, incluindo um nomograma. Foram identificados 30 diferentes factores prognósticos, embora nenhum factor fosse comum a todos os modelos prognósticos. Os factores mais frequentemente incluídos foram: número de metástases hepáticas, envolvimento ganglionar regional do tumor primário, nível sérico de CEA pré-operatório e tamanho máximo das metástases. A amostra mediana foi de 305 doentes (81-1 568 doentes) e o seguimento mediano foi de 33 meses (16-54 meses). Todos os estudos foram retrospectivos e utilizaram o modelo proporcional de Cox para análise multivariada.Conclusão: Vários factores têm sido constantemente reportados como tendo valor prognostico após ressecção de metástases hepáticas de cancro colorectal, no entanto, não existe consenso sobre o modelo ideal de prognóstico.

    The aim of this study was to update a previous scoring system for patients with skeletal metastases, that was proposed by Katagiri et al. in 2005, by introducing a new factor (laboratory data) and analyzing a new patient cohort. Between January 2005 and January 2008, we treated 808 patients with symptomatic skeletal metastases. They were prospectively registered regardless of their treatments, and the last follow-up evaluation was performed in 2012. There were 441 male and 367 female patients with a median age of 64 years. Of these patients, 749 were treated nonsurgically while the remaining 59 underwent surgery for skeletal metastasis. A multivariate analysis was conducted using the Cox proportional hazards model. We identified six significant prognostic factors for survival, namely, the primary lesion, visceral or cerebral metastases, abnormal laboratory data, poor performance status, previous chemotherapy, and multiple skeletal metastases. The first three factors had a larger impact than the remaining three. The prognostic score was calculated by adding together all the scores for individual factors. With a prognostic score of ≥7, the survival rate was 27% at 6 months, and only 6% at 1 year. In contrast, patients with a prognostic score of ≤3 had a survival rate of 91% at 1 year, and 78% at 2 years. Comparing the revised system with the previous one, there was a significantly lower number of wrongly predicted patients using the revised system. This revised scoring system was able to predict the survival rates of patients with skeletal metastases more accurately than the previous system and may be useful for selecting an optimal treatment.

    Purpose: To investigate the prognostic significance of tumor volume reduction rate (TVRR) after preoperative chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC). Methods and Materials: In total, 430 primary LARC (cT3-4) patients who were treated with preoperative CRT and curative radical surgery between May 2002 and March 2008 were analyzed retrospectively. Pre- and post-CRT tumor volumes were measured using three-dimensional region-of-interest MR volumetry. Tumor volume reduction rate was determined using the equation TVRR (%) = (pre-CRT tumor volume - post-CRT tumor volume) Multiplication-Sign 100/pre-CRT tumor volume. The median follow-up period was 64 months (range, 27-99 months) for survivors. Endpoints were disease-free survival (DFS) and overall survival (OS). Results: The median TVRR was 70.2% (mean, 64.7% {+-} 22.6%; range, 0-100%). Downstaging (ypT0-2N0M0) occurred in 183 patients (42.6%). The 5-year DFS and OS rates were 77.7% and 86.3%, respectively. In the analysis that included pre-CRT and post-CRT tumor volumes and TVRR as continuous variables, only TVRR was an independent prognostic factor. Tumor volume reduction rate was categorized according to a cutoff value of 45% and included with clinicopathologic factors in the multivariate analysis; ypN status, circumferential resection margin, and TVRR were significant prognostic factors for both DFS and OS. Conclusions: Tumor volume reduction rate was a significant prognostic factor in LARC patients receiving preoperative CRT. Tumor volume reduction rate data may be useful for tailoring surgery and postoperative adjuvant therapy after preoperative CRT.

    Primary gastric squamous cell carcinoma (SCC) is an exceedingly rare disease. We increased the understanding of gastric SCC and evaluated prognostic factors of gastric SCC.In this large-population cohort study, we retrospectively collected 163 primary gastric SCC and 66,209 primary gastric adenocarcinoma cases from the surveillance, epidemiology, and end results program (SEER) database from 1988 to 2012. The Chi-squared test demonstrated the distributed differences. Cox proportional hazards regression model was used to evaluate the prognostic factors.Gastric SCC accounted for 0.2% of all the primary gastric cancer cases. The mean age of patients with gastric SCC was 69.6 years old, and the man-to-woman ratio was 2.3:1. The proportion of black was higher in gastric SCC than gastric adenocarcinoma (P < 0.001). Almost half of the gastric SCCs were diagnosed in stage IV and more than half were poorly differentiated. In gastric SCC, the median survival was 8.0 months and the 5-year overall survival (OS) was 32.7%; in gastric adenocarcinoma the median survival rate was 19.0 months and the 5-year OS was 35.4%. The multivariate analysis showed that number of primary lesions, tumor location, grade, and stage were independent prognostic factors in gastric SCC. The tumor stage was the most important prognostic factor.Primary gastric SCC is exceedingly rare. Compared with gastric adenocarcinoma, gastric SCC was more frequent in black patients and was usually diagnosed when it was poorly differentiated and at a later stage. On the whole, gastric SCC has a poorer outcome. Disease stage is likely a key determinant in survival. PMID:27559983

    Abstract In this study, outcomes of patients with leukocytoclastic vasculitis (LCV) were analyzed focusing on clinical, histopathology and laboratory findings, relapses, and survival. Data from patients with cutaneous vasculitis diagnosed between January 1, 2000, and December 31, 2010, at Dijon University Hospital (France) were retrospectively reviewed. LCV was defined as perivascular neutrophilic infiltrate, endothelial cell nuclear swelling, extravasation of red blood cells, and/or fibrin deposition in vessels. Patients were classified according to the 2012 Chapel Hill Consensus Conference. Relapses were defined as the recurrence of vasculitis symptoms after a period of remission >1 month. Time to relapse and/or death was calculated from the date of diagnosis. Univariate and multivariate (Cox model) analyses were performed. A total of 112 patients (57 males and 55 females), with a mean age of 60 ± 19 (18–98) years, were analyzed. Overall follow-up was 61 ± 38 months. At diagnosis, all patients had skin lesions, purpura being the most common (n = 83). Lesions were associated with systemic involvement in 55 (51%) patients. Only 41 (36.6%) patients received specific treatment: glucocorticoids in 29 of 41 (70.7%) and immunosuppressants in 9 of 41 (22%). Sixty-two patients (55%) had LCV due to underlying causes, 29 (25.9%) had single-organ cutaneous small vessel vasculitis (SoCSVV), and 21 (18.8%) had unclassifiable LCV. Twenty patients of the cohort (18%) experienced relapse, 14 ± 13 (1–40) months after the diagnosis of LCV. None of the 29 patients with SoCSVV relapsed. Independent risk factors for relapse were vascular thrombosis in the biopsy [hazard ratio (HR) = 4.9; P = 0.017], peripheral neuropathy (HR = 9.8; P = 0.001), hepatitis (HR = 3.1; P = 0.004), and positive antineutrophil cytoplasm antibodies (ANCA, HR = 5.9 P = 0.005). In contrast, SoCSVV was a protective factor for relapse (HR = 0.12; P = 0.043). The 1-, 3-, and 6-year overall

Methods The medical records of 120 eyes from 60 patients with congenital aniridia were retrospectively reviewed. The prevalence and clinical course of ophthalmic characteristics, systemic disease, refractive errors, and visual acuity were assessed. Prognostic factors for final visual outcomes were analyzed. Results Aniridic keratopathy developed in 82 (69%) of 119 eyes. Macular hypoplasia was observed in 70 eyes of 35 patients (91%). Cataract was observed in 63 of 120 eyes (53%). Nystagmus was present in 41 patients (68% of 60 patients) at the initial visit but decreased in five patients (8% of 60 patients). Ocular hypertension was detected in 19 eyes (20% of 93 eyes), six (32% of 19 eyes) of which developed secondarily after cataract surgery. The mean changes in spherical equivalent and astigmatism during the follow-up period were -1.10 and 1.53 diopter, respectively. The mean final visual acuity was 1.028 logarithm of minimal angle of resolution. Nystagmus and ocular hypertension were identified as prognostic factors for poor visual outcome. Conclusions Identification of nystagmus and ocular hypertension was important to predict final visual outcome. Based on the high rate of secondary ocular hypertension after cataract surgery, careful management is needed. PMID:25435751

    Purpose: As chemotherapy has improved, the survival of patients with metastatic colorectal carcinoma has reached up to 2.5 years. Many of these patients experience pulmonary metastases; however, the prognosis after pulmonary metastasectomy is not satisfying. In this study, we analyzed the prognostic factors for survival in patients who underwent pulmonary metastasectomy. Methods: Eighty-seven patients with colorectal carcinoma received pulmonary metastasectomy. The pathological status of the primary tumor, outcome of the pulmonary metastasectomy, disease-free interval, perioperative carcinoembryonic antigen (CEA) level and history of liver metastases were assessed. Results: The five-year survival was 42.5% after pulmonary metastasectomy. A univariate analyses revealed that the CEA level (p = 0.043) and the number of pulmonary metastases (p = 0.047) were prognostic factors for survival. The CEA level was an independent prognostic factor in a multivariate analysis (relative risk = 2.01, p = 0.037). Among cases with elevated preoperative CEA levels, those whose CEA level normalized after metastasectomy had a better prognosis compared with those whose CEA level decreased but was still high, or whose level increased after metastasectomy (median survival time of 41.8 months compared with 28.1 or 15.7 months, respectively p = 0.021). Conclusion: The CEA level can be a predictive marker for the prognosis in patients with pulmonary metastases from colorectal carcinoma. PMID:26289631

    Purpose To assess the clinical profile, treatment outcome, and prognostic factors in primary spinal epidural lymphoma (PSEL). Methods and Materials Between 1982 and 2002, 52 consecutive patients with PSEL were treated in nine institutions of the Rare Cancer Network. Forty-eight patients had an Ann Arbor stage IE and four had a stage IIE. Forty-eight patients underwent decompressive laminectomy, all received radiotherapy (RT) with (n = 32) or without chemotherapy (n = 20). Median RT dose was 36 Gy (range, 6-50 Gy). Results Six (11%) patients progressed locally and 22 (42%) had a systemic relapse. At last follow-up, 28 patients were alive and 24 had died. The 5-year overall survival, disease-free survival, and local control were 69%, 57%, and 88%, respectively. In univariate analyses, favorable prognostic factors were younger age and complete neurologic response. Multivariate analysis showed that combined modality treatment, RT volume, total dose more than 36 Gy, tumor resection, and complete neurologic response were favorable prognostic factors. Conclusions Primary spinal epidural lymphoma has distinct clinical features and outcome, with a relatively good prognosis. After therapy, local control is excellent and systemic relapse occurs in less than half the cases. Combined modality treatment appears to be superior to RT alone.

    Purpose. To perform multivariate analysis for identifying independent predictors of elevated intraocular pressure (IOP) with neovascular glaucoma (NVG), including antivascular endothelial growth factor (VEGF) intravitreal injections. Methods. We retrospectively reviewed 142 NVG patients (181 eyes) with ischemic retinal diseases [proliferative diabetic retinopathy (PDR) in 134 eyes, retinal vein occlusion (RVO) in 29, and ocular ischemic syndrome in 18]. We analyzed age, gender, initial/final LogMAR VA, initial/final IOP, extent of iris and/or angle neovascularization, treatments, preexisting complications, concurrent medications, and follow-up duration. Results. The mean follow-up duration was 23.8 ± 18.8 months. At the final follow-up, 125 (72.3%) eyes had IOP ≤ 21 mmHg. NVG patients with RVO had a higher degree of angle closure and higher IOP. NVG with PDR had better IOP and LogMAR VA. Angle closure had the greatest impact on final IOP. Greater than 90% of patients treated with trabeculectomy with mitomycin C (LEC) had persistent declines in IOP (≤21 mmHg). Stand-alone and combination anti-VEGF therapies were not associated with improved long-term prognosis of IOP. Conclusions. Angle closure was found to have the greatest effect on NVG-IOP prognosis. When target IOP values are not obtained after adequate PRP with or without anti-VEGF, early LEC may improve the prognosis of IOP. PMID:27579175

    From 1991 until 2013, 304 patients with intracranial hematomas from aneurysmal rupture were managed surgically in our department, constituting 17 % of all patients with aneurysmal rupture. Of them, 242 patents presented with isolated intracerebral hematomas (in 69 cases associated with significant intraventricular hemorrhage), 50 patients presented with combined intracerebral and subdural hematomas (in 11 cases associated with significant intraventricular hemorrhage), and 12 presented with an isolated subdural hematoma. The surgical procedure consisted of simultaneous clipping of the aneurysm and evacuation of the hematoma in all cases. After surgery, 16 patients (5 %) submitted to an additional decompressive hemicraniectomy, and 66 patients (21 %) submitted to a ventriculo-peritoneal shunt. Clinical outcomes were assessed at discharge and at 6 months, using the modified Rankin Scale (mRS); a favorable outcome (mRS 0-2) was observed in 10 % of the cases at discharge, increasing to 31 % at 6 months; 6-month mortality was 40 %. Applying uni- and multivariate analysis, the following risk factors were associated with a significantly worse outcome: age >60; preoperative Hunt-Hess grades IV-V; pupillary mydriasis (only on univariate); midline shift >10 mm; hematoma volume >30 cc; and the presence of hemocephalus (i.e., packed intraventricular hemorrhage). Based on these results, an aggressive surgical treatment should be adopted for most cases with aneurysmal hematomas, excluding patients with bilateral mydriasis persisting after rescue therapy.

    Using Affymetrix microarrays, we identified the expression of the CD200 gene in multiple myeloma cells (MMCs) of 112 patients with newly diagnosed multiple myeloma (MM). The CD200 gene was either absent or present (Affymetrix call) in 22% and 78% of MMCs, respectively. The CD200 gene is not expressed in cells of the patients' bone marrow (BM). CD200 is a membrane glycoprotein that imparts an immunoregulatory signal through CD200R, leading to the suppression of T-cell-mediated immune responses. Patients with CD200(absent) MMCs have an increased event-free survival (EFS; 24 months) compared with patients with CD200(present) MMCs (14 months), after high-dose therapy and stem cell transplantation. In a Cox proportional-hazard model, the absence or presence of CD200 expression in MMCs is predictive for EFS for patients independently of ISS stage or beta2M serum levels. Thus, CD200 is an independent prognosis factor for patients with MM that could represent a new therapeutic target in MM.

    The value of bevacizumab (BEV) in recurrent glioblastoma is unclear. Imaging parameters and progression-free survival (PFS) are problematic endpoints. Few data exist on clinical factors influencing overall survival (OS) in unselected patients with recurrent glioblastoma exposed to BEV. We retrospectively analyzed 174 patients with recurrent glioblastoma treated with BEV at two German brain tumor centers. We evaluated general patient characteristics, MGMT status, pretreatment, concomitant oncologic treatment and overall survival. Karnofsky performance score, number of prior chemotherapies, number of prior recurrences and combined treatment with irinotecan (IRI) were significantly associated with OS in univariate analysis. We did not find differences in OS related to sex, age, histology, MGMT status, prior surgical treatment or number of prior radiotherapies. Combined treatment with IRI and higher KPS both remained significantly associated with prolonged survival in multivariate analysis, but patients receiving IRI co-treatment had less advanced disease. Grouping into clinically relevant categories revealed an OS of 16.9 months from start of BEV in patients with first recurrence and KPS ≥ 80 % (n = 25). In contrast, in patients with second recurrence and KPS < 80 %, OS was 3.6 months (n = 27). Our observational data support an early use of BEV in patients with good performance status. The benefit of co-treatment with IRI in our cohort seems to be the result of biased patient recruitment. PMID:27193554

  3. Prognostic factors and biomarkers of congenital obstructive nephropathy.

    PubMed

    Chevalier, Robert L

    2016-09-01

    Congenital obstructive nephropathy (CON) is the leading cause of chronic kidney disease (CKD) in children. Anomalies of the urinary tract are often associated with abnormal nephrogenesis, which is compounded by obstructive injury and by maternal risk factors associated with low birth weight. Currently available fetal and postnatal imaging and analytes of amniotic fluid, urine, or blood lack predictive value. For ureteropelvic junction obstruction, biomarkers are needed for optimal timing of pyeloplasty; for posterior urethral valves, biomarkers of long-term prognosis and CKD are needed. The initial nephron number may be a major determinant of progression of CKD, and most patients with CON who progress to renal failure reach this point in adulthood, presumably compounded by episodes of acute kidney injury. Biomarkers of tubular injury may be of particular value in predicting the need for surgical intervention or in tracking progression of CKD, and must be adjusted for patient age. Discovery of new biomarkers may depend on "unbiased" proteomics, whereby patterns of urinary peptide fragments from patients with CON are analyzed in comparison to controls. Most promising are the analysis of urinary exosomes (restricting biomarkers to relevant tubular cells) and quantitative magnetic resonance imaging techniques allowing precise determination of nephron number and tubular mass. The greatest need is for large prospective multicenter studies with centralized biomarker sample repositories to follow patients with CON from fetal life through adulthood.

    Purpose The objective of this study is to investigate the prognostic value of primary tumor inflammation (PTI) in nasopharyngeal carcinoma (NPC) in the era of intensity-modulated radiation therapy (IMRT). Results PTI was observed in 376/1708 (22.0%) patients, and was present in the sphenoid sinus in 289/376 (76.9%), in the nasal cavity in 27 (7.2%), and in both places in 60 (15.9%). The estimated 4-year local relapse-free survival (LRFS), disease-free survival (DFS), overall survival (OS) and distant metastasis-free survival (DMFS) rates for PTI vs. non-PTI group were 89.2% vs. 96.1% (P < 0.001), 73.4% vs. 85.1% (P < 0.001), 85.0% vs. 92.1% (P < 0.001) and 83.6% vs. 91.4% (P < 0.001), respectively. After adjustment for these known prognostic factors, PTI was confirmed as an independent prognostic factor for LRFS (HR 2.152, 95% CI 1.318–3.516, P = 0.002), DFS (HR 1.581, 95% CI 1.204–2.077, P = 0.001) and DMFS (HR 1.682, 95% CI 1.177–2.402, P = 0.004). Conclusions Primary tumor inflammation was identified as a strong prognostic factor for patients with NPC in the era of IMRT and should be considered when devising future treatment strategies aimed at improving survival in NPC patients. Materials and Methods Data on 1708 patients with nonmetastatic, histologically-confirmed NPC treated with IMRT between November 2009 and February 2012 at Sun Yat-Sen University Cancer Center were retrospectively reviewed. Patient survival between PTI and non-PTI groups were compared. PMID:26934649

    Objective. To analyze the clinical outcomes and prognostic factors of intensity-modulated radiotherapy (IMRT) for T4 stage nasopharyngeal carcinoma (NPC). Methods. Between March 2005 and March 2010, 110 patients with T4 stage NPC without distant metastases were treated. All patients received IMRT. Induction and/or concurrent chemotherapy were given. 47 (42.7%) patients received IMRT replanning. Results. The 5-year local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 90.1%, 97.0%, 67.5%, 63.9%, and 64.5%, respectively. Eleven patients experienced local-regional failure and total distant metastasis occurred in 34 patients. 45 patients died and 26 patients died of distant metastasis alone. The 5-year LRFS rates were 97.7% and 83.8% for the patients that received and did not receive IMRT replanning, respectively (P = 0.023). Metastasis to the retropharyngeal lymph nodes (RLN) was associated with inferior 5-year OS rate (61.0% versus 91.7%, P = 0.034). The gross tumor volume of the right/left lymph nodes (GTVln) was an independent prognostic factor for DMFS (P = 0.006) and PFS (P = 0.018). GTVln was with marginal significance as the prognostic factor for OS (P = 0.050). Conclusion. IMRT provides excellent local-regional control for T4 stage NPC. Benefit of IMRT replanning may be associated with improvement in local control. Incorporating GTVln into the N staging system may provide better prognostic information. PMID:27195286

    Between April 1968 and February 1988, 311 patients with symptomatic and progressive Graves' ophthalmopathy were treated with megavoltage orbital radiotherapy. The patients were divided into three groups: I treated with 20 Gy/2 weeks; II treated with 30 Gy/3 weeks, and III received 20 Gy/2 weeks. The degree of eye involvement was evaluated numerically before and after therapy for each of five parameters: soft tissue signs, proptosis, eye muscle impairment, corneal involvement, and sight loss. Pre-treatment and current thyroid diagnosis and status were also noted. To evaluate the effects of radiotherapy alone, follow-up was terminated at the time any eye surgery was done; for those not treated surgically the minimum follow-up was 12 months. Because there were significant demographic differences between the patient groups, the results of each group were analyzed separately. A stepwise linear regression analysis was performed to determine if there were any significant variables affecting outcome. Based on these data formulae were derived which enable outcome to be predicted in any patient. Before therapy more than 90% of patients in all groups had soft tissue and eye muscle involvement, whereas 65-75% had proptosis and about half 50% had some degree of sight loss. Radiotherapy arrested progression of ophthalmic parameters in all but 1-6% of the patients. Objective and symptomatic improvement was noted for all parameters assessed, but there was marked individual variability. The best responses were noted for soft tissue, corneal involvement, and sight loss; however over half the patients had some improvement in eye muscle function and proptosis. Factors which resulted in less favorable outcome included male gender, advanced age, need for concurrent therapy for hyperthyroidism, and no history of hyperthyroidism. No complications have been observed.

    Background and Purpose We investigated the potential role of serum procalcitonin in differentiating tuberculosis meningitis from bacterial and viral meningitis, and in predicting the prognosis of tuberculosis meningitis. Methods This was a retrospective study of 26 patients with tuberculosis meningitis. In addition, 70 patients with bacterial meningitis and 49 patients with viral meningitis were included as the disease control groups for comparison. The serum procalcitonin level was measured in all patients at admission. Differences in demographic and laboratory data, including the procalcitonin level, were analyzed among the three groups. In addition, we analyzed the predictive factors for a prognosis of tuberculosis meningitis using the Glasgow Coma Scale (GCS) at discharge, and the correlation between the level of procalcitonin and the GCS score at discharge. Results Multiple logistic regression analysis showed that a low level of procalcitonin (≤1.27 ng/mL) independently distinguished tuberculosis meningitis from bacterial meningitis. The sensitivity and specificity for distinguishing tuberculosis meningitis from bacterial meningitis were 96.2% and 62.9%, respectively. However, the level of procalcitonin in patients with tuberculosis meningitis did not differ significantly from that in patients with viral meningitis. In patients with tuberculosis meningitis, a high level of procalcitonin (>0.4 ng/mL) was a predictor of a poor prognosis, and the level of procalcitonin was negatively correlated with the GCS score at discharge (r=-0.437, p=0.026). Conclusions We found that serum procalcitonin is a useful marker for differentiating tuberculosis meningitis from bacterial meningitis and is also valuable for predicting the prognosis of tuberculosis meningitis.

    Although Morganella morganii causes a variety of clinical infections, there are limited studies on M. morganii bacteremia after the year 2000. A total of 109 patients with M. morganii bacteremia at a medical center in Taiwan from 2003 to 2012 were studied. Among them, 30.3 % had polymicrobial bacteremia and 75.2 % had community-acquired infection. The most common underlying diseases were hypertension (62.4 %) and diabetes mellitus (38.5 %). The urinary tract (41.3 %) was the major portal of entry, followed by the hepatobiliary tract (27.5 %), skin and soft tissue (21.1 %), and primary bacteremia (10.1 %). Susceptibility testing of M. morganii isolates showed ubiquitous resistance to first-generation cephalosporins and ampicillin-clavulanate; resistance rates to gentamicin, piperacillin-tazobactam, and ciprofloxacin were 30.3 %, 1.8 %, and 10.1 %, respectively. Overall, the 14-day mortality was 14.7 %. Univariate analysis revealed that elevated blood urea nitrogen (BUN) values [p = 0.0137, odds ratio (OR) 5.26], intensive care unit (ICU) admission (p = 0.011, OR 4.4), and higher Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (p < 0.001, OR 1.62) were significantly associated with mortality. The APACHE II score remained the only significant risk factor for mortality in multivariate analysis (p = 0.0012, OR 1.55). In conclusion, M. morganii bacteremia patients were mostly elderly, with one or more comorbidities. Most of the patients had community-acquired infection via the urinary and hepatobiliary tracts. Furthermore, prognosis can be predicted according to disease severity measured by the APACHE II score.

    Purpose: To retrospectively analyze and assess the outcomes and prognostic factors in a large number of patients with atypical and malignant meningiomas. Methods and Materials: Ten academic medical centers participating in this Rare Cancer Network contributed 119 cases of patients with atypical or malignant meningiomas treated with external beam radiotherapy (EBRT) after surgery or for recurrence. Eligibility criteria were histologically proven atypical or anaplastic (malignant) meningioma (World Health Organization Grade 2 and 3) treated with fractionated EBRT after initial resection or for recurrence, and age >18 years. Sex ratio (male/female) was 1.3, and mean ({+-}SD) age was 57.6 {+-} 12 years. Surgery was macroscopically complete (Simpson Grades 1-3) in 71% of patients; histology was atypical and malignant in 69% and 31%, respectively. Mean dose of EBRT was 54.6 {+-} 5.1 Gy (range, 40-66 Gy). Median follow-up was 4.1 years. Results: The 5- and 10-year actuarial overall survival rates were 65% and 51%, respectively, and were significantly influenced by age >60 years (p = 0.005), Karnofsky performance status (KPS) (p = 0.01), and high mitotic rate (p = 0.047) on univariate analysis. On multivariate analysis age >60 years (p = 0.001) and high mitotic rate (p = 0.02) remained significant adverse prognostic factors. The 5- and 10-year disease-free survival rates were 58% and 48%, respectively, and were significantly influenced by KPS (p 0.04) and high mitotic rate (p = 0.003) on univariate analysis. On multivariate analysis only high mitotic rate (p = 0.003) remained a significant prognostic factor. Conclusions: In this multicenter retrospective study, age, KPS, and mitotic rate influenced outcome. Multicenter prospective studies are necessary to clarify the management and prognostic factors of such a rare disease.

    Objective To describe the clinical and laboratory features of children and adolescents with acute lymphoblastic leukemia treated at three referral centers in Ceará and evaluate prognostic factors for survival, including age, gender, presenting white blood cell count, immunophenotype, DNA index and early response to treatment. Methods Seventy-six under 19-year-old patients with newly diagnosed acute lymphoblastic leukemia treated with the Grupo Brasileiro de Tratamento de Leucemia da Infância – acute lymphoblastic leukemia-93 and -99 protocols between September 2007 and December 2009 were analyzed. The diagnosis was based on cytological, immunophenotypic and cytogenetic criteria. Associations between variables, prognostic factors and response to treatment were analyzed using the chi-square test and Fisher's exact test. Overall and event-free survival were estimated by Kaplan–Meier analysis and compared using the log-rank test. A Cox proportional hazards model was used to identify independent prognostic factors. Results The average age at diagnosis was 6.3 ± 0.5 years and males were predominant (65%). The most frequently observed clinical features were hepatomegaly, splenomegaly and lymphadenopathy. Central nervous system involvement and mediastinal enlargement occurred in 6.6% and 11.8%, respectively. B-acute lymphoblastic leukemia was more common (89.5%) than T-acute lymphoblastic leukemia. A DNA index >1.16 was found in 19% of patients and was associated with favorable prognosis. On Day 8 of induction therapy, 95% of the patients had lymphoblast counts <1000/μL and white blood cell counts <5.0 × 109/L. The remission induction rate was 95%, the induction mortality rate was 2.6% and overall survival was 72%. Conclusion The prognostic factors identified are compatible with the literature. The 5-year overall and event-free survival rates were lower than those reported for developed countries. As shown by the multivariate analysis, age and baseline white

Methods Between January 2008 and December 2011, all patients with STEMI undergoing primary PCI were retrospectively included in this study. Baseline characteristics and angiographic data were reviewed and recorded. The study endpoint was all-cause in-hospital mortality. Results Of the 541 patients included in the study, 63 (11.6%) died during hospitalisation. Cardiogenic shock at admission was recorded in 301 patients (55.6%) and 424 patients (78%) had multivessel disease. Median door-to-device time was 65 min. After adjustment for baseline variables, the factors associated with in-hospital mortality included age >60 years (OR 2.98, 95% CI 1.17 to 7.05; p=0.01), left ventricular ejection fraction <40% (OR 2.53, 95% CI 1.20 to 5.36; p=0.02), and final TIMI flow grade 0/1 (OR 20.55, 95% CI 3.49 to 120.94; p=0.001). Conclusions Age, left ventricular function and final TIMI flow are significant predictors of adverse outcomes in unselected patients with STEMI undergoing primary PCI. PMID:27347008

    Although long-term outcomes of meningoencephalitis of unknown aetiology (MUA) in dogs have been evaluated, little is known about short-term survival and initial response to therapy. The aim of this study was to evaluate possible prognostic factors for 7-day survival after diagnosis of MUA in dogs. Medical records were reviewed for dogs diagnosed with MUA between 2006 and 2015. Previously described inclusion criteria were used, as well as 7-day survival data for all dogs. A poor outcome was defined as death within 1 week. Of 116 dogs that met inclusion criteria, 30 (26%) died within 7 days of diagnosis. Assessed variables included age, sex, bodyweight, duration of clinical signs and treatment prior to diagnosis, venous blood glucose and lactate levels, white blood cell count on complete blood count, total nucleated cell count/total protein concentration/white blood cell differentiation on cerebrospinal fluid (CSF) analysis, presence of seizures and cluster seizures, mentation at presentation, neuroanatomical localisation, imaging findings and treatment after diagnosis. Multivariate analysis identified three variables significantly associated with poor outcome; decreased mentation at presentation, presence of seizures, and increased percentage of neutrophils on CSF analysis. Despite initiation of appropriate treatment, more than a quarter of dogs died within 1 week of diagnosis of MUA, emphasising the need for evaluation of short-term prognostic factors. Information from this study could aid clinical staff to provide owners of affected dogs with prognostic information. PMID:27387733

    Background: Glutamate decarboxylase 1 (GAD1) which serves as a rate-limiting enzyme involving in the production of γ-aminobutyric acid (GABA), exists in the GABAergic neurons in the central nervous system (CNS). Little is known about the relevance of GAD1 to nasopharyngeal carcinoma (NPC). Through data mining on a data set derived from a published transcriptome database, this study first identified GAD1 as a differentially upregulated gene in NPC. We aimed to evaluate GAD1 expression and its prognostic effect on patients with early and locoregionally advanced NPC. Methods: We evaluated GAD1 immunohistochemistry and performed an H-score analysis on biopsy specimens from 124 patients with nonmetastasized NPC receiving treatment. GAD1 overexpression was defined as an H score higher than the median value. The findings of such an analysis are correlated with clinicopathological behaviors and survival rates, namely disease-specific survival (DSS), distant-metastasis-free survival (DMeFS), and local recurrence-free survival (LRFS) rates. Results: GAD1 overexpression was significantly associated with an increase in the primary tumor status (p < 0.001) and American Joint Committee on Cancer (AJCC) stages III-IV (p = 0.002) and was a univariate predictor of adverse outcomes of DSS (p = 0.002), DMeFS (p < 0.0001), and LRFS (p = 0.001). In the multivariate comparison, in addition to advanced AJCC stages III-IV, GAD1 overexpression remained an independent prognosticator of short DSS (p = 0.004, hazard ratio = 2.234), DMeFS (p < 0.001, hazard ratio = 4.218), and LRFS (p = 0.013, hazard ratio = 2.441) rates. Conclusions: Our data reveal that GAD1 overexpression was correlated with advanced disease status and may thus be a critical prognostic indicator of poor outcomes in NPC and a potential therapeutic target to facilitate the development of effective treatment modalities.

    Vaidya, R.; Witzig, T. E.

    2014-01-01

    Background The introduction of rituximab (R) to conventional CHOP chemotherapy for newly diagnosed diffuse large B-cell lymphoma (DLBCL) led to an unequivocal improvement in survival, establishing RCHOP as the standard of care. Still, nearly 40% of DLBCL patients will eventually die of relapsed disease. Efforts to improve outcomes by addition of new biologic agents (X) to the RCHOP backbone are underway. In this era of R(X)CHOP, it is imperative to develop prognostic and predictive markers, not only to identify patients who will suffer a particularly aggressive course, but also to accurately select patients for clinical trials from which they will most benefit. Design The following review was undertaken to describe prognostic factors in DLBCL, with emphasis on markers that are accurate, relatively available, and clinically applicable in 2014. Results The International Prognostic Index retains its validity in the era of RCHOP, although with limited ability to predict those with <50% chance of long-term survival. Gene expression profiling has provided novel insights into the biology of DLBCL and led to the development of immunohistochemistry (IHC) algorithms that are in routine practice. Identification of a ‘double-hit’ (DH) lymphoma by fluorescent in situ hybridization with aberrations involving MYC and/or BCL2 and BCL6 genes has important implications due to its extremely dismal prognosis with RCHOP. Other markers such as the absolute lymphocyte count (ALC), serum immunoglobulin free light chains, vitamin D levels, serum cytokines/chemokines, and imaging with positron emission tomography (PET) have all shown promise as future predictive/prognostic tests. Conclusions The future for new treatment options in DLBCL is promising with current clinical trials testing novel targeted agents such as bortezomib, lenalidomide, and ibrutinib as the ‘X’ in R(X)CHOP. Predictive factors are required to select and randomize patients appropriately for these trials. We

  17. A profile of prognostic and molecular factors in European and Māori breast cancer patients

    PubMed Central

    2010-01-01

    Background New Zealand Māori have a poorer outcome from breast cancer than non-Māori, yet prognostic data are sparse. The objective of this study was to quantify levels of prognostic factors in a cohort of self-declared Māori and European breast cancer patients from Christchurch, New Zealand. Methods and Results Clinicopathological and survival data from 337 consecutive breast cancer patients (27 Māori, 310 European) were evaluated. Fewer tumours were high grade in Māori women than European women (p = 0.027). No significant ethnic differences were detected for node status, tumour type, tumour size, human epidermal growth factor receptor, oestrogen and progesterone receptor (ER/PR) status, or survival. In addition, tumour and serum samples from a sub-cohort of 14 Māori matched to 14 NZ European patients were analyzed by immunohistochemistry and enzyme linked immunosorbent assay for molecular prognostic factors. Significant correlations were detected between increased grade and increased levels of hypoxia inducible factor-1 (HIF-1α), glucose transporter-1 (GLUT-1), microvessel density (MVD) and cytokeratins CK5/6 (p < 0.05). High nodal status correlated with reduced carbonic anhydrase IX (CA-IX). Negative ER/PR status correlated with increased GLUT-1, CA-IX and MVD. Within the molecular factors, increased HIF-1α correlated with raised GLUT-1, MVD and CK5/6, and CK5/6 with GLUT-1 and MVD (p < 0.05). The small number of patients in this sub-cohort limited discrimination of ethnic differences. Conclusions In this Christchurch cohort of breast cancer patients, Māori women were no more likely than European women to have pathological or molecular factors predictive of poor prognosis. These data contrast with data from the North Island NZ, and suggest potential regional differences. PMID:20932344

  18. Comparing the importance of prognostic factors in Cox and logistic regression using SAS.

    2003-06-01

    Two SAS macro programs are presented that evaluate the relative importance of prognostic factors in the proportional hazards regression model and in the logistic regression model. The importance of a prognostic factor is quantified by the proportion of variation in the outcome attributable to this factor. For proportional hazards regression, the program %RELIMPCR uses the recently proposed measure V to calculate the proportion of explained variation (PEV). For the logistic model, the R(2) measure based on squared raw residuals is used by the program %RELIMPLR. Both programs are able to compute marginal and partial PEV, to compare PEVs of factors, of groups of factors, and even to compare PEVs of different models. The programs use a bootstrap resampling scheme to test differences of the PEVs of different factors. Confidence limits for P-values are provided. The programs further allow to base the computation of PEV on models with shrinked or bias-corrected parameter estimates.

    2016-01-01

    Background Basic fibroblast growth factor (bFGF) is known to stimulate angiogenesis and thus to influence the proliferation, migration and survival of tumor cells. Many studies examined the relationship between human bFGF overexpression and survival in lung cancer patients, but the results have been mixed. To systematically summarize the clinical prognostic function of bFGF in lung cancer, we performed this systematic review with meta-analysis. Method Studies were identified by an electronic search of PubMed, EMBASE, China National Knowledge Infrastructure and Wanfang databases, including publications prior toAugust 2014. Pooled hazard ratios (HR) for overall survival (OS) were aggregated and quantitatively analyzed by meta-analysis. Results Twenty-two studies (n = 2154) were evaluated in the meta-analysis. Combined HR suggested that bFGF overexpression had an adverse impact on survival of patients with lung cancer(HR = 1.202,95%CI, 1.022–1.382). Our subgroup analysis revealed that the combined HR evaluating bFGF expression on OS in operable non-small cell lung cancer (NSCLC) was 1.553 (95%CI, 1.120–1.986); the combined HR in small cell lung cancer (SCLC) was 1.667 (95%CI, 1.035–2.299). There was no significant impact of bFGF expression on survival in advanced NSCLC. Conclusion This meta-analysis showed that bFGF overexpression is a potential indicator of worse prognosis for patients with operable NSCLC and SCLC, but is not associated with outcome in advanced NSCLC. The data suggests that high bFGF expression is highly related to poor prognosis. Nevertheless,more high-quality studies should be performed in order to provide additional evidence for the prognostic value of bFGF in lung cancer. PMID:26824699

    Background Suicide is a leading cause of death worldwide, but the precise effect of childhood adversities as risk factors for the onset and persistence of suicidal behaviour (suicide ideation, plans and attempts) are not well understood. Aims To examine the associations between childhood adversities as risk factors for the onset and persistence of suicidal behaviour across 21 countries worldwide. Method Respondents from nationally representative samples (n = 55 299) were interviewed regarding childhood adversities that occurred before the age of 18 years and lifetime suicidal behaviour. Results Childhood adversities were associated with an increased risk of suicide attempt and ideation in both bivariate and multivariate models (odds ratio range 1.2–5.7). The risk increased with the number of adversities experienced, but at a decreasing rate. Sexual and physical abuse were consistently the strongest risk factors for both the onset and persistence of suicidal behaviour, especially during adolescence. Associations remained similar after additional adjustment for respondents’ lifetime mental disorder status. Conclusions Childhood adversities (especially intrusive or aggressive adversities) are powerful predictors of the onset and persistence of suicidal behaviours. PMID:20592429

    HES1 is the target of Notch signaling which is reported to affect cell differentiation and maintain the cells in G0 phase in various tissues including the hematopoietic tissue. HES1 expression appears to be an independent prognostic factor for survival in a heterogeneous group of acute myeloid leukemia (AML) patients. To better assess its significance, we analyzed HES1 expression in a group of non-core binding factor AML patients and correlated its expression with the overall survival and relapse-free survival of AML patients. First, we detected the messenger RNA expression of HES1 in 40 patients with AML by real-time polymerase chain reaction. The top 50% of AML cases with the high HES1 expression were compared with the rest of the AML cohort. Overall survival was calculated from the date of diagnosis until the date of death from any cause or until the date of final follow-up. Relapse-free survival was determined for responders from the time of diagnosis until relapse or death from any cause. We showed that the lower-expression group had a shorter overall survival time and shorter relapse-free survival time compared with those of the high-expression group (37.6±1.6 versus 54.0±1.3 months, 28.6±1.8 months versus 44.8±2.1 months, respectively, P<0.05), and Cox regression showed that HES1 was an independent prognostic factor. In all, we conclude that expression of HES1 is a useful prognostic factor for patients with non-core binding factor AML. PMID:25960660

    BACKGROUND--Studies attempting to identify the prognostic factors that influence the outcome of Pneumocystis carinii pneumonia (PCP) in patients with AIDS using a multivariate analysis are few. In order to identify those prognostic factors amenable to medical intervention, univariate and multivariate analyses were performed on 102 patients with AIDS suffering a first episode of PCP. METHODS--One hundred and two consecutive patients with AIDS (51% drug abusers, 45% homosexuals, and 4% with other HIV risk factors) admitted to our institution between 1986 and 1989 whose respiratory infection was diagnosed by bronchoalveolar lavage were studied prospectively. RESULTS--The overall mortality was 28%, rising to 79% in those patients who required mechanical ventilation. According to univariate analysis the following variables were related to a poor prognosis: age > 35 years; risk factor for HIV infection other than drug abuse; and AIDS diagnosis confirmed before 1988; PaO2 < 8 kPa at admission; severe acute respiratory failure on admission (PaO2/FIO2 < 20 kPa); mechanical ventilation; antibiotic therapy for PCP other than trimethoprim-sulphamethoxazole; multiple microbial pulmonary infection; serum lactate dehydrogenase (LDH) > 22.5 mukat/l on admission; serum albumin level < 30 g/l. Multivariate analysis showed that only mechanical ventilation was independently associated with a poor outcome. CONCLUSIONS--The mortality of AIDS patients presenting with a first episode of PCP before 1990 was high (28%). The main prognostic factor associated with poor outcome was the requirement for mechanical ventilation due to severe acute respiratory failure. PMID:7638811

    This study explores the correlation between molybdenum target (mo-target) mammography signs and pathological prognostic factors of breast cancer. We selected 320 breast cancer patients who were treated between January 2014 and January 2016; using single-factor and multiple-factor logistic regression method, we made correlation analysis on their clinical features, pathological features and mo-target mammography signs. Among mo-target mammography signs, lumps accompanied with calcification and blurry edge were associated with high histologic grades; lumps accompanied with calcification and clear edge were associated with Ki-67 positive; compared with the patients who had lumps with non-stellate edges, positive rates of estrogen receptor (ER) and progesterone receptor (PR) were significantly higher for the patients who had lumps with stellate edges (p < 0.01), while positive rate of human epidermal growth factor receptor-2 (HER-2) and tumor proliferative activity were significantly lower (p < 0.05, p < 0.01). According to the study, we can conclude that mo-target mammography signs mainly include lumps and calcification. Mo-target mammography can improve the accuracy of diagnosis and reduce misdiagnosis or missed diagnosis. Part of mo-target mammography signs are associated with clinical pathology prognostic factors; by grasping the relation, breast cancer patient conditions are expected to be relieved.

    Background and study aims: Endoscopic resection is one treatment option for residual or locally recurrent esophageal cancer after definitive chemoradiotherapy or radiotherapy alone. However, little is known about the clinical benefit of salvage endoscopic resection for these lesions. Therefore, the effectiveness and prognostic factors of salvage endoscopic resection were investigated. Patients and methods: A total of 37 patients with esophageal squamous cell carcinoma (SCC) who underwent salvage endoscopic resection after definitive chemoradiotherapy or radiotherapy alone were reviewed. The method of salvage endoscopic resection was endoscopic mucosal resection using a cap (EMR-C), strip biopsy, or endoscopic submucosal dissection. The effectiveness and prognostic factors of salvage endoscopic resection were retrospectively analyzed. Results: A total of 37 patients with 49 lesions underwent salvage endoscopic resection. Baseline clinical stages were I in 23 patients, II in 3 patients, III in 9 patients, and IV in 2 patients. The number of locoregional recurrences and residual lesions were 35 and 14, respectively. The curative en bloc resection rate was 53.1 % (26/49). The total incidence of complications was 18.9 % (7/37); all were successfully managed conservatively. The 3-year and 5-year overall survival rates were 72.9 % and 53.3 %, respectively, with a median follow-up period of 54 months. Baseline clinical T1 – 2 and N0 were significant factors for good prognosis in terms of overall survival on univariate analysis. Conclusions: Salvage endoscopic resection, especially EMR-C, is a safe and feasible procedure to control residual or recurrent superficial esophageal SCC after definitive chemoradiotherapy or radiotherapy alone. The present results showed that baseline clinical T1 – 2 and N0 before chemoradiotherapy or radiotherapy were significant prognostic factors. PMID:27540571

    Background It is widely known that the prognosis of acute myeloid leukemia (AML) depends on chromosomal abnormalities. The majority of AML patients relapse and experience a dismal disease course despite initial remission. Methods We reviewed the medical records and laboratory findings of 55 AML patients who had relapsed between 2004 and 2013 and who had been treated at the Division of Hematology of the Pusan National University Hospital. Results The event-free survival (EFS) was related to prognostic karyotype classification at the time of diagnosis and relapse (unfavorable vs. favorable or intermediate karyotypes at diagnosis, 8.2 vs. 11.9 mo, P=0.003; unfavorable vs. favorable or intermediate karyotypes at relapse, 8.2 vs. 11.9 mo, P=0.009). The overall survival (OS) was significantly correlated with karyotype classification only at diagnosis (unfavorable vs. favorable or intermediate vs. karyotypes at diagnosis, 8.5 vs. 21.8 mo, P=0.001; unfavorable vs. favorable or intermediate karyotypes at relapse, 8.5 vs. 21.2 mo, P=0.136). A change in karyotype between diagnosis and relapse, which is regarded as a factor of resistance against treatment, was not a significant prognostic factor for OS, EFS, and post-relapse survival (PRS). A Cox proportional hazards model showed that the combined use of fludarabine, cytosine arabinoside, and granulocyte colony-stimulating factor (FLAG) as a salvage regimen, was a significant prognostic factor for OS (hazard ratio=0.399, P=0.010) and the PRS (hazard ratio=0.447, P=0.031). Conclusion The karyotype classification at diagnosis predicts survival including PRS in relapsed AML patients as well as in treatment-naïve patients. We suggest that presently, administration of salvage FLAG could be a better treatment option. PMID:27722128

    AIM: To investigate macrophage migration inhibitory factor (MIF) expression and its clinical relevance in gastric cancer, and effects of MIF knockdown on proliferation of gastric cancer cells. METHODS: Tissue microarray containing 117 samples of gastric cancer and adjacent non-cancer normal tissues was studied for MIF expression by immunohistochemistry (IHC) semiquantitatively, and the association of MIF expression with clinical parameters was analyzed. MIF expression in gastric cancer cell lines was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. Two pairs of siRNA targeting the MIF gene (MIF si-1 and MIF si-2) and one pair of scrambled siRNA as a negative control (NC) were designed and chemically synthesized. All siRNAs were transiently transfected in AGS cells with OligofectamineTM to knock down the MIF expression, with the NC group and mock group (OligofectamineTM alone) as controls. At 24, 48, and 72 h after transfection, MIF mRNA was analyzed by RT-PCR, and MIF and proliferating cell nuclear antigen (PCNA) proteins were detected by Western blot. The proliferative rate of AGS cells was assessed by methylthiazolyl tetrazolium (MTT) assay and colony forming assay. RESULTS: The tissue microarray was informative for IHC staining, in which the MIF expression in gastric cancer tissues was higher than that in adjacent non-cancer normal tissues (P < 0.001), and high level of MIF was related to poor tumor differentiation, advanced T stage, advanced tumor stage, lymph node metastasis, and poor patient survival (P < 0.05 for all). After siRNA transfection, MIF mRNA was measured by real-time PCR, and MIF protein and PCNA were assessed by Western blot analysis. We found that compared to the NC group and mock group, MIF expression was knocked down successfully in gastric cancer cells, and PCNA expression was downregulated with MIF knockdown as well. The cell counts and the doubling times were assayed by MTT 4 d after transfection, and

    Ninety-three cases of drowning or near-drowning in the pediatric age group between 1972 and 1976 were reviewed. A scoring system for prognostic factors was developed using one point for each of five unfavorable factors involved in the drowning or near-drowning of each patient. The prognostic factors were 1) age less than three years; 2) maximum submersion time estimated longer than five minutes; 3) resuscitation not attempted for at least ten minutes after rescue; 4) patient in coma on admission to hospital, and 5) arterial blood pH of less than or equal to 7.10. This scoring system significantly predicted the eventual outcome of patients who had experienced the postsubmersion syndrome. Patients with scores of less than or equal to 2 had a 90% chance of full recovery; those with scores of greater than or equal to 3 had only a 5% probability of survival. The early institution of resuscitative efforts was the single most important factor influencing survival.

    Strong theoretical reasons exist for using fractal geometry in measurements of natural objects, including most objects studied in pathology. Indeed, fractal dimension provides a more precise and theoretically more appropriate approximation of their structure properties and especially their shape complexity. The aim of our study was to evaluate the nuclear fractal dimension (FD) in tissue specimens from patients with oral cavity carcinomas in order to assess its potential value as prognostic factor. Relationships between FD and other factors including clinicopathologic characteristics were also investigated. Histological sections from 48 oral squamous cell carcinomas as well as from 17 non-malignant mucosa specimens were stained with Hematoxylin-Eosin for pathological examination and with Feulgen for nuclear complexity evaluation. The sections were evaluated by image analysis using fractal analysis software to quantify nuclear FD by the box-counting method. Carcinomas presented higher mean values of FD compared to normal mucosa. Well differentiated neoplasms had lower FD values than poorly differentiated ones. FD was significantly correlated with the nuclear size. Patients with FD lower than the median value of the sample had statistically significant higher survival rates. Within the sample of patients studied, FD was proved to be an independent prognostic factor of survival in oral cancer patients. In addition this study provides evidence that there are several statistically significant correlations between FD and other morphometric characteristics or clinicopathologic factors in oral squamous cell carcinomas.

    The detection of epithelial cells in bone marrow, blood or lymph nodes indicates a disseminatory potential of solid tumours. 225 patients with squamous cell carcinoma of the oesophagus were prospectively studied. Prior to any therapy, cytokeratin-positive (CK) cells in bone marrow were immunocytochemically detected in 75 patients with the monoclonal anti-epithelial-cell antibody A45-B/B3 and correlated with established histopathologic and patient-specific prognosis factors. The prognosis factors were assessed by multivariate analysis. Twenty-nine of 75 (38.7%) patients with oesophageal cancer showed CK-positive cells in bone marrow. The analyses of the mean and median overall survival time showed a significant difference between patients with and without epithelial cells in bone marrow (P< 0.001). Multivariate analysis in the total patient population and in patients with curative resection of the primary tumour confirmed the curative resection rate and the bone marrow status as the strongest independent prognostic factors, besides the T-category. The detection of epithelial cells in bone marrow of oesophageal cancer patients is a substantial prognostic factor proved by multivariate analysis and is helpful for exact preoperative staging, as well as monitoring of neoadjuvant therapy. © 2000 Cancer Research Campaign PMID:10883665

    2010-01-01

    Background We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. Methods This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Results Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Conclusion Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered. PMID:21182799

    To determine the clinical features, prognostic factors, and therapeutic results of Guillain-Barré syndrome (GBS) in order to improve the therapeutic strategy for this disease. We retrospectively reviewed the electrodiagnostic study and medical records of patients with GBS admitted to Chang Gung Memorial Hospital, Kaohsiung, between January 1986 and December 2000. Outcomes and prognosis were followed-up after 1 year. Ninety-six patients were enrolled in this study. According to the clinical and electrophysiological findings, 77 patients were acute inflammatory demyelinating polyradiculoneuropathy, seven were Miller Fisher syndrome, and six were axonal forms, and six were unclassified. At a follow-up of 1 year, 61 patients (64%) recovered, 30 (31%) had residua and five (5%) died. Amongst these 30 had residua, including unassisted gait in 19, assisted gait in four, and wheel/bed bound in seven. According to the statistical analysis, disabilities at the nadir (P < 0.0001) and at admission (P = 0.014) were significant prognostic factors. Variables used for the stepwise logistic regression, and the results revealed that after analysis for all the above variables, only disability at the nadir (P < 0.0001) was independently associated with the treatment failure rate. Our study revealed 27% of cases in need of respiratory support during hospitalization, and 5% of hospital-treated patients die from the complications. Furthermore, 31% had residua at a follow-up of 1 year or more. If prognostic factors are considered, disability at the nadir during hospitalization demonstrates consistently poor therapeutic outcomes. Therefore, early diagnosis, choice of appropriate treatment, and preventing complications during acute stages are essential to maximize the potential for survival.

    To identify clinical and histologic prognostic factors and to investigate whether immunohistochemical detection of p53 expression might contain prognostic information, a retrospective study of patient and tumor characteristics was performed in 225 cases of papillary and follicular thyroid carcinomas. The analyses were based on cause-specific and crude survival. In univariate analysis, age at diagnosis, tumor size, presence of distant metastases, histology (papillary contra follicular type), extrathyroidal invasion, necrosis in primary tumor, and p53 expression were significant prognostic indicators. For 211 patients (96%) all information was available and Cox's proportional hazard model was applied. The authors found that age, distant metastases, necrosis in primary tumor, extrathyroidal invasion, and p53 expression were significant prognostic factors. Analyses of cause-specific and crude survival gave similar results. The authors conclude that age at diagnosis, presence of distant metastases, necrosis in primary tumor, and extrathyroidal invasion are important prognostic factors, and that immunohistochemical detection of p53 protein in the primary tumor is a significant and independent prognostic indicator, which might be of value in the treatment planning in patients with papillary or follicular thyroid carcinomas.

    Objective: To assess the effect of prognostic factors and their impact on survival in male and female breast cancer. Methods: Medical records for men and women diagnosed with breast cancer referred to the cancer center for treatment were reviewed. Patients with distant metastatic diseases were excluded. Data on prognostic factors including age, nodal status, resection margin, use of hormonal therapy, chemotherapy with and without hormone and radiation therapy (RT), survival, and recurrence were analyzed. Survival estimates were obtained using Kaplan-Meier methodology. The Cox regression interaction was used to compare male and female differences in prognostic factors. Male breast cancer (MBC) and female breast cancer (FBC) were matched according to propensity scores and survival compared using Cox regression. Results: From 1963-2006, there were 75 MBC and 1,313 FBC totaling 1,388 breast cancers. The median age of the cohort was 53 (range: 23-90) years. Median follow-up was 90 (range: 0.4-339) months. Prognostic factors of patients were balanced among the groups after adjusting for propensity scores. A Cox model adjusting for propensity scores showed that overall survival (OS) (HR= 2.52 (1.65, 3.86), P<0.001) and distant disease recurrence-free survival (DDRFS) (HR= 2.39 (0.75, 3.04), P=0.003) were significantly different for MBC and FBC. Analyses that stratified by propensity score quintiles had similar findings: OS HR=2.41 (1.67, 3.47), P<0.001); DDRFS HR=2.89 (1.81, 4.60), P<0.001). When MBC and FBC were matched (1:3) by propensity scores, differences between MBC and FBC were again observed in OS (HR=1.94, 95%CI:1.18-3.19, P=0.009) and DDRFS (HR=2.79, 95%CI:1.36-5.75, P=0.005) with MBC at a higher risk of death and  disease recurrence compared to FBC . Conclusion: This large series showed that MBC and FBC survivals are not similar, with MBC having a worse outcome. The finding of this study needs confirmation from a complete prospective database.

    Background The role of reduced intensity conditioning allogeneic stem transplantation (RICalloSCT) in the management of patients with Hodgkin’s lymphoma remains controversial. Design and Methods To further define its role we have conducted a retrospective analysis of 285 patients with HL who underwent a RICalloSCT in order to identify prognostic factors that predict outcome. Eighty percent of patients had undergone a prior autologous stem cell transplantation and 25% had refractory disease at transplant. Results Non-relapse mortality was associated with chemorefractory disease, poor performance status, age >45 and transplantation before 2002. For patients with no risk factors the 3-year non-relapse mortality rate was 12.5% compared to 46.2% for patients with 2 or more risk factors. The use of an unrelated donor had no adverse effect on the non-relapse mortality. Acute graft versus host disease (aGVHD) grades II–IV developed in 30% and chronic GVHD in 42%. The development of cGVHD was associated with a lower relapse rate. The disease progression rate at one and five years was 41% and 58.7% respectively and was associated with chemorefractory disease and extent of prior therapy. Donor lymphocyte infusions were administered to 64 patients for active disease of whom 32% showed a clinical response. Eight out of 18 patients receiving donor lymphocyte infusions alone had clinical responses. Progression-free and overall survival were both associated with performance status and disease status at transplant. Patients with neither risk factor had a 3-year PFS and overall survival of 42% and 56% respectively compared to 8% and 25% for patients with one or more risk factors. Relapse within six months of a prior autologous transplant was associated with a higher relapse rate and a lower progression-free. Conclusions This analysis identifies important clinical parameters that may be useful in predicting the outcome of RICaIICalloSCT in Hodgkin’s lymphoma. PMID:19066328

    Purpose: To retrospectively assess prognostic factors and patterns of recurrence in patients with pathologic Stage III endometrial cancer. Methods and Materials: Between 1989 and 2003, 107 patients with pathologic International Federation of Gynecology and Obstetrics Stage III endometrial adenocarcinoma confined to the pelvis were treated at our institution. Adjuvant radiotherapy (RT) was delivered to 68 patients (64%). The influence of multiple patient- and treatment-related factors on pelvic and distant control and overall survival (OS) was evaluated. Results: Median follow-up for patients at risk was 41 months. Five-year actuarial OS was significantly improved in patients treated with adjuvant RT (68%) compared with those with resection alone (50%; p = 0.029). Age, histology, grade, uterine serosal invasion, adnexal involvement, number of extrauterine sites, and treatment with adjuvant RT predicted for improved survival in univariate analysis. Multivariate analysis revealed that grade, uterine serosal invasion, and treatment with adjuvant RT were independent predictors of survival. Five-year actuarial pelvic control was improved significantly with the delivery of adjuvant RT (74% vs. 49%; p = 0.011). Depth of myometrial invasion and treatment with adjuvant RT were independent predictors of pelvic control in multivariate analysis. Conclusions: Multiple prognostic factors predicting for the outcome of pathologic Stage III endometrial cancer patients were identified in this analysis. In particular, delivery of adjuvant RT seems to be a significant independent predictor for improved survival and pelvic control, suggesting that pelvic RT should be routinely considered in the management of these patients.

    Background Patients who are admitted with a suspicion of a severe infection usually enter the hospital through the emergency department (ED). The recognition of prognostic factors in an early stage affects further treatment and might improve clinical outcomes. Aims We examined possible prognostic factors for four important outcomes: intensive care unit (ICU) admission, positive blood cultures, mortality and re-admission. Methods All adult patients arriving at the ED with a suspected infection for whom admittance and intravenous (iv) antibiotics were indicated were included between March and December 2006. Possible prognostic variables were obtained from medical history, physical examination and laboratory results during the ED presentation. Data were analysed using logistic regression analysis. Results A total of 295 ED patients were evaluated, of whom 27 were referred to the ICU, 62 had a positive blood culture, 16 died and 48 were re-admitted. In multivariate analysis, patients with a respiration rate of >25/min were at higher risk for ICU admission. Patients with a positive blood culture had a higher heart rate and a higher percentage of segmented neutrophils. Patients who died during admission were more likely to be older, confused and had lower blood pressure. Patients who were re-admitted within 30 days were more likely to be male, younger and less likely to have a positive blood culture. Conclusions Routine clinical and biochemical information can be used to predict ICU admission, the presence of bacteraemia, mortality and re-admission (within 30 days) and should be taken into consideration for treatment decisions.

    The influence of vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) on prognosis and the relationship between VEGF expression and MVD in ovarian carcinoma are not well defined. We studied VEGF expression in parallel with MVD by immunohistochemistry in 94 ovarian tumours (64 malignant, 13 borderline, and 17 benign) and correlated the results with the clinicopathologic prognostic factors of the disease to clarify their significance in this disease. Assessment of VEGF mRNA isoforms by RT-PCR was also performed. Of the malignant, borderline, and benign ovarian tumours respectively, two (3%), four (31%) and 16 (94%) were negative, 31 (48%), seven (54%) and one (6%) had low expressions, and 31 (48%), two (15%) and none (0%) had high expressions of VEGF. There were significant associations between the VEGF expression and disease stage (P = 0.002), histologic grade (P = 0.0004), and patient outcome (P = 0.0002). MVD did not correlate significantly with the clinicopathologic parameters. Likewise, no correlation was found between MVD and VEGF expression. The survival of patients with high VEGF expression was significantly worse than that of patients with low and negative VEGF expression (P = 0.0004). Multivariate analysis revealed that disease stage and VEGF expression were significant and independent prognostic indicators of overall survival time (P = 0.008 and P = 0.006 respectively). These findings suggest that in conjunction with the established clinicopathologic prognostic parameters of ovarian carcinoma, VEGF expression may enhance the predictability of patients at high risk for tumour progression who are potential candidates for further aggressive therapy. © 2000 Cancer Research Campaign PMID:10901370

    Summary Large cell transformation of mycosis fungoides (MF-LCT) occurs in 20–50% of advanced MF, and is generally associated with poor prognosis, although some patients have indolent disease. We sought to identify clinicopathological prognostic factors in a large number of patients with MF-LCT. We identified patients with MF-LCT treated between 1991 and 2012 at a referral centre for cutaneous lymphoma. Clinical and pathological records, and histopathological slides were reviewed. Associations of clinicopathological variables with disease-specific survival were analysed. In 51 patients with MF-LCT, factors significantly associated with shorter survival were: age >60 years (25 versus 61 months, p = 0.01), stage III/IV (25 versus 44 months, p = 0.049), high serum lactate dehydrogenase (LDH; 24 versus 53 months, p = 0.007), absent papillary dermal involvement (8 versus 30 months, p = 0.008); follicular mucin at transformation (24 versus 42 months, p = 0.007); and the absence of fibrosis at transformation (21 versus 42 months, p = 0.03). Patients presenting with transformation at diagnosis had better survival than those who started with a small cell phenotype (p = 0.02). Age >60 years was independently associated with poorer survival (HR 5.61, 95%CI 1.17–26.8, p = 0.03), and the presence of fibrosis at transformation was independently associated with improved survival (HR 0.30, 95%CI 0.09–0.97, p = 0.045). In patients with MF-LCT, clinical features (age, stage, serum LDH) are important in assessing prognosis. Additional clinical and pathological features identified in this study may also assist in prognostic stratification. Studies of larger cohorts should be performed to validate the prognostic significance of these features. PMID:25393251

    With a worldwide incidence estimated at 8-15 per 100,000 population a year, idiopathic sudden sensorineural hearing loss (ISSHL) is a common clinical finding for otologists. There is a shortage of information on the clinical factors capable of predicting hearing recovery and response to therapy. The aim of the present study was to retrospectively investigate the prognostic value of clinical variables in relation to hearing recovery, in a cohort of 117 consecutive patients with ISSHL. Clinical parameters (signs, symptoms, comorbidities and treatments) and audiometric data were analyzed with univariate and multivariate statistical approaches for prognostic purposes to identify any correlation with hearing recovery, also expressed according to the Wilson criteria. Univariate analysis showed that age and hypertension were significantly related to hearing outcome (p = 0.004 and p = 0.015, respectively). Elderly patients and those with hypertension were at higher risk of experiencing no hearing recovery (OR = 3.25 and OR = 2.89, respectively). Age was an independent prognostic factor on multivariate analysis (p = 0.007). Tinnitus as a presenting symptom showed a trend towards an association with hearing recovery (p = 0.07). The treatment regimen, the time elapsing between the onset of symptoms and the start of therapy (p = 0.34), and the duration of the treatment (p = 0.83) were unrelated to recovery on univariate analysis. Among the parameters considered, only age was significantly and independently related to hearing outcome. There is a need for well-designed, randomized clinical trials to enable an evidence-based protocol to be developed for the treatment of ISSHL.

    Background We conducted a nationwide study in Denmark to identify clinical features and prognostic factors in patients with Streptococcus pneumoniae according to the focus of infection. Methods Based on a nationwide registration, clinical information's was prospectively collected from all reported cases of pneumococcal meningitis during a 2-year period (1999–2000). Clinical and laboratory findings at admission, clinical course and outcome of the disease including follow-up audiological examinations were collected retrospectively. The focus of infection was determined according to the clinical diagnosis made by the physicians and after review of the medical records. Results 187 consecutive cases with S. pneumoniae meningitis were included in the study. The most common focus was ear (30%), followed by lung (18%), sinus (8%), and other (2%). In 42% of cases a primary infection focus could not be determined. On admission, fever and an altered mental status were the most frequent findings (in 93% and 94% of cases, respectively), whereas back rigidity, headache and convulsion were found in 57%, 41% and 11% of cases, respectively. 21% of patients died during hospitalisation (adults: 27% vs. children: 2%, Fisher Exact Test, P < 0.001), and the causes of death were due to neurological – and systemic complications or the combination of both in 8%, 5% and 6% of cases, respectively. Other causes (e.g. gastrointestinal bleeding, incurable cancer) accounted for 2% of cases. 41% of survivors had neurological sequelae (hearing loss: 24%, focal neurological deficits: 16%, and the combination of both: 1%). The mortality varied with the focus of the infection (otogenic: 7%, sinusitic: 33%, pneumonic: 26%, other kind of focus: 50%, no primary infection focus: 21%, Log rank test: P = 0.0005). Prognostic factors associated with fatal outcome in univariate logistic regression analysis were advanced age, presence of an underlying disease, history of headache, presence of a lung focus

    Purpose: A prognostic index for survival was constructed and validated from patient data from two European Organisation for Research and Treatment of Cancer (EORTC) radiation trials for low-grade glioma (LGG). We sought to independently validate this prognostic index with a separate prospectively collected data set (Intergroup 86-72-51). Methods and Materials: Two hundred three patients were treated in a North Central Cancer Treatment Group-led trial that randomized patients with supratentorial LGG to 50.4 or 64.8 Gy. Risk factors from the EORTC prognostic index were analyzed for prognostic value: histology, tumor size, neurologic deficit, age, and tumor crossing the midline. The high-risk group was defined as patients with more than two risk factors. In addition, the Mini Mental Status Examination (MMSE) score, extent of surgical resection, and 1p19q status were also analyzed for prognostic value. Results: On univariate analysis, the following were statistically significant (p < 0.05) detrimental factors for both progression-free survival (PFS) and overall survival (OS): astrocytoma histology, tumor size, and less than total resection. A Mini Mental Status Examination score of more than 26 was a favorable prognostic factor. Multivariate analysis showed that tumor size and MMSE score were significant predictors of OS whereas tumor size, astrocytoma histology, and MMSE score were significant predictors of PFS. Analyzing by the EORTC risk groups, we found that the low-risk group had significantly better median OS (10.8 years vs. 3.9 years, p < 0.0001) and PFS (6.2 years vs. 1.9 years, p < 0.0001) than the high-risk group. The 1p19q status was available in 66 patients. Co-deletion of 1p19q was a favorable prognostic factor for OS vs. one or no deletion (median OS, 12.6 years vs. 7.2 years; p = 0.03). Conclusions: Although the low-risk group as defined by EORTC criteria had a superior PFS and OS to the high-risk group, this is primarily because of the influence of

    Colorectal cancer (CRC) is a highly heterogeneous disease regarding the stage at time of diagnosis and there is special attention regarding adjuvant chemotherapy in unselected patients with stage I and stage II. The clinicohistologically based TNM staging system with emphasis on histological evaluation of primary tumor and resected regional lymph nodes remains the standard of staging, but it has restricted sensitivity resulting in false downward stage migration. Molecular characteristics might predispose tumors to a worse prognosis and identification of those enables identifying patients with high risk of disease recurrence. Suitable predictive markers also enable choosing the most appropriate therapy. The current challenge facing adjuvant chemotherapy in stages I and II CRC is choosing patients with the highest risk of disease recurrence who are going to derive most benefit without facing unnecessary adverse effects. Single nucleotide polymorphisms (SNPs) are one of the potential molecular markers that might help us identify patients with unfavorable prognostic factors regarding disease initiation and recurrence and could determine selection of an appropriate chemotherapy regimen in the adjuvant and metastatic setting. In this paper, we discuss SNPs of genes involved in the multistep processes of cancerogenesis, metastasis, and the metabolism of chemotherapy that might prove clinically significant. PMID:26884752

    Background: The aim is to correlate pulmonary arterial (PA) remodeling estimated by PA fibrosis in PA hypertension (PAH) with clinical follow-up. Histology of PA specimens is also performed. Methods: 19 patients, aged 54±16 (4 men), functional class II-III were studied with right heart catheterization, PA Intravascular Ultrasound and optical coherence tomography (OCT) in inferior lobe segment. PA wall fibrosis was obtained by OCT ( area of fibrosis/PA cross sectional area × 100). Patients follow-up was blind to OCT. Events were defined as mortality, lung transplantation, need of intravenous prostaglandins or onset of right ventricular failure. Results: OCT measurements showed high intra- and interobserver agreement. There was a good correlation between OCT and histology in PA fibrosis from explanted lungs. Area of fibrosis was 1.4±0.8 mm2, % fibrosis was 22.3±8. Follow-up was 3.5 years (2.5-4.5). OCT %Fib was significantly correlated with PA capacitance (r=-0.536) and with pulmonary vascular rsistance (r=0.55). Patients were divided according to the median value of PA fibrosis. There were 10 patients with a high (≥ 22%) and 9 with a low fibrosis (<22%). Events occurred in 6 (1 death, 1 lung transplantation, 2 intravenous prostaglandins, 2 right heart failure) out of 10 patients with high and in 0 out of 9 patients with low fibrosis (p<0.01). Conclusions: In PAH, the severity of PA remodeling assessed by OCT wall fibrosis was significantly predictive of severely unfavorable clinical outcome. In vivo assessment of pulmonary arterial wall fibrosis by intravascular OCT in PAH is a promising new prognostic marker of adverse clinical outcome. PMID:23730366

    Abstract Multiple endocrine neoplasia type 1 (MEN1) is classically characterized by the development of functional or nonfunctional hyperplasia or tumors in endocrine tissues (parathyroid, pancreas, pituitary, adrenal). Because effective treatments have been developed for the hormone excess state, which was a major cause of death in these patients in the past, coupled with the recognition that nonendocrine tumors increasingly develop late in the disease course, the natural history of the disease has changed. An understanding of the current causes of death is important to tailor treatment for these patients and to help identify prognostic factors; however, it is generally lacking. To add to our understanding, we conducted a detailed analysis of the causes of death and prognostic factors from a prospective long-term National Institutes of Health (NIH) study of 106 MEN1 patients with pancreatic endocrine tumors with Zollinger-Ellison syndrome (MEN1/ZES patients) and compared our results to those from the pooled literature data of 227 patients with MEN1 with pancreatic endocrine tumors (MEN1/PET patients) reported in case reports or small series, and to 1386 patients reported in large MEN1 literature series. In the NIH series over a mean follow-up of 24.5 years, 24 (23%) patients died (14 MEN1-related and 10 non-MEN1-related deaths). Comparing the causes of death with the results from the 227 patients in the pooled literature series, we found that no patients died of acute complications due to acid hypersecretion, and 8%–14% died of other hormone excess causes, which is similar to the results in 10 large MEN1 literature series published since 1995. In the 2 series (the NIH and pooled literature series), two-thirds of patients died from an MEN1-related cause and one-third from a non-MEN1-related cause, which agrees with the mean values reported in 10 large MEN1 series in the literature, although in the literature the causes of death varied widely. In the NIH and pooled

    Brain metastasis (BM) in patients with breast cancer is a catastrophic event that results in poor prognosis. Identification of prognostic factors associated with breast cancer brain metastases (BCBM) could help to identify patients at risk. The aim of this study was to assess clinical characteristics, prognostic factors, and survival of patients with BCBM who had craniotomy and resection in a series of patients treated with modern multimodality therapy. We analyzed 42 patients with BCBM who underwent resection. Patients were diagnosed with breast cancer between April 1994 and May 2010. Cox proportional hazards regression was selected to describe factors associated with time to BM, survival from the date of first recurrence, and overall survival (OS). Median age was 51 years (range 24-74). Median follow-up was 4.2 years (range 0.6-18.5). The proportion of the biological subtypes of breast cancer was ER+/HER2- 25%, ER+/HER2+ 15%, ER-/HER2+ 30%, and ER-/HER2- 30%. Median OS from the date of primary diagnosis was 5.74 years. Median survival after diagnosis of BM was 1.33 years. In multivariate Cox regression analyses, stage was the only factor associated with shorter time to the development of BM (P = 0.033), whereas age was the only factor associated with survival from the date of recurrence (P = 0.027) and with OS (P = 0.037). Stage at primary diagnosis correlated with shorter time to the development of BM, while age at diagnosis was associated with shorter survival in BCBM. None of the other clinical factors had influence on survival.

    Relative survival methods permit separating the effects of prognostic factors on disease-related 'excess mortality' from their effects on other-causes 'natural mortality', even when individual causes of death are unknown. As in conventional 'crude' survival, accurate assessment of prognostic factors requires testing and possibly modeling of non-proportional effects and, for continuous covariates, of non-linear relationships with the hazard. We propose a flexible extension of the additive-hazards relative survival model, in which the observed all-causes mortality hazard is represented by a sum of disease-related 'excess' and natural mortality hazards. In our flexible model, the three functions representing (i) the baseline hazard for 'excess' mortality, (ii) the time-dependent effects, and (iii) for continuous covariates, non-linear effects, on the logarithm of this hazard, are all modeled by low-dimension cubic regression splines. Non-parametric likelihood ratio tests are proposed to test the time-dependent and non-linear effects. The accuracy of the estimated functions is evaluated in multivariable simulations. To illustrate the new insights offered by the proposed model, we apply it to re-assess the effects of patient age and of secular trends on disease-related mortality in colon cancer.

    Purpose This study aimed to determine which factors affect the prognosis of hepatectomy for hepatocellular carcinoma (HCC) larger than 5 cm, including the prognostic difference between tumor sizes from 5–10 cm and larger than 10 cm. Methods The medical records of 114 patients who underwent hepatectomy for single HCC larger than 5 cm were reviewed and analyzed retrospectively. Results In the analysis of the entire cohort of 114 patients, the 5-year overall and diseases-free survival rates were 50% and 29%, respectively. In a comparison of survival rates between groups, tumor sizes of 5 to 10 cm and larger than 10 cm, the overall and disease-free survival rates were not significantly different, respectively (54% vs. 41%, P = 0.433 and 33% vs. 23%, P = 0.083). On multivariate analysis, positive hepatitis B, high prothrombin induced by vitamin K absence or antagonist-II levels over 200 mIU/mL, and vascular invasion (micro- and macrovascular invasion) were independent prognostic factors for recurrence after hepatic resection. However, tumor size larger than 10 cm was not significant for recurrence after resection. Conclusion This study shows that surgical resection of solitary HCC larger than 5 cm showed favorable overall survival. And there is no survival difference with tumors between 5–10 cm and larger than 10 cm. PMID:27617250

    In medial tibial stress syndrome (MTSS) bone marrow and periosteal edema of the tibia on the magnetic resonance imaging (MRI) is frequently reported. The relationship between these MRI findings and recovery has not been previously studied. This prospective study describes MRI findings of 52 athletes with MTSS. Baseline characteristics were recorded and recovery was related to these parameters and MRI findings to examine for prognostic factors. Results showed that 43.5% of the symptomatic legs showed bone marrow or periosteal edema. Absence of periosteal and bone marrow edema on MRI was associated with longer recovery (P = 0.033 and P = 0.013). A clinical scoring system for sports activity (SARS score) was significantly higher in the presence of bone marrow edema (P = 0.027). When clinical scoring systems (SARS score and the Lower Extremity Functional Scale) were combined in a model, time to recovery could be predicted substantially (explaining 54% of variance, P = 0.006). In conclusion, in athletes with MTSS, bone marrow or periosteal edema is seen on MRI in 43,5% of the symptomatic legs. Furthermore, periosteal and bone marrow edema on MRI and clinical scoring systems are prognostic factors. Future studies should focus on MRI findings in symptomatic MTSS and compare these with a matched control group.

    Purpose To investigate associations between dyspnea and clinical outcomes in patients with non-small cell lung cancer (NSCLC). Materials and Methods From 2001 to 2014, we retrospectively reviewed the prospective lung cancer database of St. Paul's Hospital at the Catholic University of Korea. We enrolled patients with NSCLC and evaluated symptoms of dyspnea using modified Medical Research Council (mMRC) scores. Also, we estimated pulmonary functions and analyzed survival data. Results In total, 457 NSCLC patients were enrolled, and 259 (56.7%) had dyspnea. Among those with dyspnea and whose mMRC scores were available (109 patients had no mMRC score), 85 (56.6%) patients had an mMRC score <2, while 65 (43.3%) had an mMRC score ≥2. Significant decreased pulmonary functions were observed in patients with dyspnea. In multivariate analysis, aging, poor performance status, advanced stage, low forced expiratory volume in 1 second (%), and an mMRC score ≥2 were found to be significant prognostic factors for patient survival. Conclusion Dyspnea could be a significant prognostic factor in patients with NSCLC. PMID:27401635

    To determine whether the coefficient of variation (CV) of nuclear diameters can be used as a prognostic factor in papillary thyroid carcinoma, we reviewed fine needle aspiration smears with Riu's stain from 55 operated-on and pathologically verified cases with a median follow-up of 6.5 years. For each case we measured the nuclear diameters of 100 cancer cells by ocular micrometry and calculated the CV of the nuclear diameters. Then we correlated the CV with the clinical stage, recurrence and death. There was a positive correlation between the CV of the nuclear diameters and the clinical stage (r = .59, P less than .0001). Recurrent cases (n = 10) had a higher CV than did those without recurrence (n = 45) (18.04 +/- 4.1% [mean +/- SD] versus 13.2 +/- 2.7%, P less than .0005). All recurrent cases had a CV greater than 13%. The cases in which death occurred (n = 5) had a higher CV than did those with survival (n = 50) (20.1 +/- 4.9% versus 13.5 +/- 2.7%, P less than .0005). All cases in which death occurred had a CV greater than 15%. The extent of variation of nuclear diameters was one of the factors influencing prognosis in papillary thyroid carcinoma. It offers a prognostic adjunct to standard clinical and histologic analysis.

    Objective To determine whether history of pre-morbid type 2 diabetes mellitus (DM2) is a prognostic factor in amyotrophic lateral sclerosis (ALS). Methods The relationship between DM2 and survival was analyzed in a study population consisting of 1,322 participants from six clinical trials. Results Survival did not differ by diabetes status (Log-Rank Test, p=0.98), but did differ by body mass index (BMI) (Log-Rank Test, p=0.008). In multivariate analysis, there was no significant association between diabetes and survival (p=0.18), but the risk of reaching a survival endpoint decreased by 4% for each unit increase in baseline BMI (HR 0.96, 95% CI 0.94–0.99, p=0.001). DM2 was less prevalent among ALS clinical trial participants than predicted. Conclusions History of pre-morbid DM2 is not an independent prognostic factor in ALS clinical trial databases. The low DM2 prevalence rate should be examined in a large, prospective study to determine whether DM2 affects ALS risk. PMID:25900666

    Purpose. To evaluate the outcome and identify the prognostic factors of traumatic endophthalmitis over a 5-year period. Methods. We reviewed the medical records of all the traumatic endophthalmities that we treated in our department over the last 5 years (2009–2013). We extracted the following parameters: age, gender, wound anatomy, associated ocular lesions, treatment, and initial and final visual acuities. We used the program SPSS version 20.0.0. for the statistical analysis of our data. Results. During the last 5 years, we treated 14 traumatic endophthalmities, representing 46.66% of all types of endophthalmities. The infection rate in open globe injuries was 8.13% and 34.78%, if an intraocular foreign body (IOFB) was associated. All the patients were males with the median age of 37 years. Initial visual acuities varied between light perception and 0.4 and the timing of treatment from a few hours to 10 days. We administered antibiotic and anti-inflammatory drugs, systemically and intravitreally, in all cases. We performed pars plana vitrectomy in 64.28% of cases. In 57.14% of cases, the final visual acuity was 0.1 or more. Conclusions. IOFBs increased significantly the risk for endophthalmitis. The worse prognostic factors were retinal detachment at presentation and delayed treatment. This trial is registered with IRCT2014082918966N1. PMID:25302113

On multivariate analysis, positive hepatitis B, high prothrombin induced by vitamin K absence or antagonist-II levels over 200 mIU/mL, and vascular invasion (micro- and macrovascular invasion) were independent prognostic factors for recurrence after hepatic resection. However, tumor size larger than 10 cm was not significant for recurrence after resection. Conclusion This study shows that surgical resection of solitary HCC larger than 5 cm showed favorable overall survival. And there is no survival difference with tumors between 5–10 cm and larger than 10 cm.

    SOX11 is involved in gastrulation and in malignant diseases. The aim of this study was to investigate the role of SOX11 in gastric cancer and its expression pattern and clinical significance. SOX11 overexpression cell model was used to examine in vitro and in vivo the role of SOX11 in cell growth and metastasis. Cell cycle analysis and Annexin V/PI double staining were used to investigate the effect of SOX11 on cell cycle progression and apoptosis. The expression of SOX11 in human gastric cancer was examined by immunohistochemistry. The correlation of SOX11 expression with clinicopathological characteristics and survival of patients was analyzed by Pearson’s χ2 and Kaplan-Meier analyses, respectively. Cox’s proportional hazard model was employed in multivariate analysis. SOX11 overexpression did not inhibit cell growth but strongly suppressed cell migration/invasion in vitro and in vivo. We found a significant correlation between high SOX11 protein levels and Lauren’s classification (intestinal type), differentiation status (high and medium), and early TNM stage. SOX11 is an independent prognostic factor for improved survival in gastric cancer patients. SOX11 was a potential tumor-suppressor and an independent positive prognostic factor in gastric cancer patients with less advanced clinicopathological features. PMID:24604109

    Purpose: The aim of study is to evaluate angiogenesis using CD34, in estrogen, progesterone positive and negative breastcancer and to correlate the microvessel density with known histological prognostic factors, morphological type of breast carcinoma and lymph node metastasis. Materials and Methods: Twenty eight untreated cases of breast cancer were included in the study and paraffin embedded sections were obtained from representative mastectomy specimen of breast cancer patient. The sections were stained with hematoxylin and eosin stain and immunohistochemistry was performed using CD34, estrogen, progesterone, cytokeratin and epithelial membrane antigen antibody. Angiogenesis was analysed using CD 34 antibody. For statistical analysis, cases were grouped into estrogen, progesterone positive and negative receptors. Results: Mean microvessel density in ER-/PR-, ER-/ PR+, ER+/PR-, ER+/PR+ was 15.45, 14.83, 11, 10.89 respectively. A significant correlation was found between ER receptors and mean vascular density with p-value (< 0.05). A significant difference was observed in mean vascular density between the four groups comprising (p-value < 0.05). Infiltrating duct carcinoma (NOS) grade III has got the highest mean microvessel density (14.17) followed by grade II (12.93) and grade I (12.33). Conclusion: Information about prognostic factors in breast cancer patients may lead to better ways to identify those patients at high risk who might benefit from adjuvant therapies. PMID:25737993

    In gynecologic oncology valid prognostic factors are necessary to define biologically similar subgroups for analysis of therapeutic efficacy. This study is the first published prospective study concerning prognostic significance of DNA ploidy and S-phase fraction in cervical and endometrial cancer following enrichment of tumor cells by cytokeratin labelling. Epithelial cells were labeled by FITC-conjugated cytokeratin antibody (CK 5, 6, 8, and CK 17) prior to flow cytometric cell cycle analysis in 91 specimens of cervical cancer and 73 samples of endometrial cancer. In cervical cancer neither DNA-ploidy nor S-phase fraction were relevant prognostic parameters. But CV of the G(0)G(1)-peak showed prognostic relevance in cervical cancer cells, even in multivariate analysis. This interesting observation, however, seems to have no therapeutic consequence due to the small discrimination capacity of CV. In endometrial carcinoma, gross DNA-aneuploidy (DNA-index > 1.3) and a high percentage of proliferating cells (>75th percentile) were univariate and multivariate highly significant prognostic factors for recurrence-free survival. Especially DNA-aneuploidy (DI>1.3) is one of the most important independent molecular biological prognostic factors. While diagnostic curettage we could identify risk patients even preoperatively by determination of the prognostic factors like histologic tumor type, grading, cervical involvement and DNA-ploidy. Thereby these patients could be treated primarily in an oncologic center. In conclusion, our investigations showed that the determination of DNA-ploidy should be done in endometrial carcinoma. In cervical cancer no clinical significance for determination of DNA-parameters was found.

    Background Malignant peripheral nerve sheath tumors (MPNST) are rare, highly malignant, and poorly understood sarcomas. The often poor outcome of MPNST highlights the necessity of identifying prognostic predictors for this aggressive sarcoma. Here, we investigate the role of fibroblast growth factor receptor (FGFR) family members in human MPNSTs. Results aCGH and bioinformatics analysis identified frequent amplification of the FGFR1 gene. FISH analysis revealed that 26.9% MPNST samples had amplification of FGFR1, with both focal and polysomy patterns observed. IHC identified that FGFR1 protein expression was positively correlated with FGFR1 gene amplification. High expression of FGFR1 protein was associated with better overall survival (OS) and was an independent prognostic predictor for OS of MPNST patients. Additionally, combined expression of FGFR1 and FGFR2 protein characterized a subtype of MPNST with better OS. FGFR4 protein was expressed 82.3% of MPNST samples, and was associated with poor disease-free survival. Materials and Methods We performed microarray-based comparative genomic hybridization (aCGH) profiling of two cohorts of primary MPNST tissue samples including 25 patients treated at The University of Texas MD Anderson Cancer Center and 26 patients from Tianjin Medical University Cancer Institute and Hospital. Fluorescence in situ hybridization (FISH) was used to validate the gene amplification detected by aCGH analysis. Another cohort of 63 formalin-fixed paraffin-embedded MPNST samples (including 52 samples for FISH assay) was obtained to explore FGFR1, 2, 3, and 4 protein expression by immunohistochemical (IHC) analysis. Conclusions Our integrated genomic and molecular studies provide evidence that FGFRs play different prognostic roles in MPNST. PMID:26993773

    Background The long-term prognosis of patients with colon cancer is dependent on many factors. To investigate the influence of a series of clinical, laboratory and morphological variables on prognosis of colon carcinoma we conducted a retrospective analysis of our data. Methods Ninety-two patients with colon cancer, who underwent surgical resection between January 1999 and December 2001, were analyzed. On survival analysis, demographics, clinical, laboratory and pathomorphological parameters were tested for their potential prognostic value. Furthermore, univariate and multivariate analysis of the above mentioned data were performed considering the depth of tumour invasion into the bowel wall as independent variable. Results On survival analysis we found that depth of tumour invasion (P < 0.001; F-ratio 2.11), type of operation (P < 0.001; F-ratio 3.51) and CT scanning (P < 0.001; F-ratio 5.21) were predictors of survival. Considering the degree of mural invasion as independent variable, on univariate analysis, we observed that mucorrhea, anismus, hematocrit, WBC count, fibrinogen value and CT scanning were significantly related to the degree of mural invasion of the cancer. On the multivariate analysis, fibrinogen value was the most statistically significant variable (P < 0.001) with the highest F-ratio (F-ratio 5.86). Finally, in the present study, the tumour site was significantly related neither to the survival nor to the mural invasion of the tumour. Conclusion The various clinical, laboratory and patho-morphological parameters showed different prognostic value for colon carcinoma. In the future, preoperative prognostic markers will probably gain relevance in order to make a proper choice between surgery, chemotherapy and radiotherapy. Nevertheless, current data do not provide sufficient evidence for preoperative stratification of high and low risk patients. Further assessments in prospective large studies are warranted.

    Background: We sought to clarify the prognostic impact of primary tumor location in metastatic colorectal cancer (mCRC). Methods: We evaluated the association between tumor location and survival parameters in patients with previously untreated mCRC receiving first-line chemotherapy ± bevacizumab in three independent cohorts: a prospective pharmacogenetic study (PROVETTA) and two randomized phase III trials, AVF2107g and NO16966. Cancers proximal or distal of the splenic flexure were classified as right-sided or left-sided, respectively. The primary end point was overall survival (OS). Data were analyzed with Cox proportional hazards and logistic regression models. All statistical tests were two-sided. Results: Among evaluable patients in the PROVETTA (n = 200), AVF2107g (n = 559), and NO16966 (n = 1268) studies, 72.0%, 63.1%, and 73.7% had left-sided tumors, respectively. In PROVETTA, patients with left-sided tumors had superior OS (left-sided vs right-sided: hazard ratio [HR] = .44, 95% confidence interval [CI] = .28 to .70, P < .001) and progression-free survival (HR = .52, 95% CI = .36 to .75, P < .001) outcomes. Multivariable analyses confirmed right-sided location as a negative prognostic variable, independent of mucinous histology and BRAF mutational status. Data from the AVF2107g (HR for OS = .55, 95% CI = .43 to .70) and NO16966 trials (HR for OS = .71, 95% CI = .62 to .82 both P < .001) also showed favorable outcomes in patients with left-sided tumors. In both randomized studies, the efficacy of bevacizumab was independent of tumor location. Conclusions: These data demonstrate that primary tumor location is an important prognostic factor in previously untreated mCRC. Given the consistency across an exploratory set and two confirmatory phase III studies, side of tumor origin should be considered for stratification in randomized trials. PMID:25713148

    In Switzerland efficient availability of novel drugs for renal cell cancer (RCC) has been granted early. Since the advent of the targeted agents for RCC the usage of these drugs has been reported to improve progression free survival. Here, we find that patients who are able to receive sequential targeted therapy, including tyrosine kinase inhibitors (TKI) and mTOR inhibitors (mTORi), have a largely better outcome than those who have less exposure to these agents. The value of the prognostic scores developed by Motzer and Heng is fully reflected by the outcomes according to prognostic risk groups in our unselected patient cohort. Also, the use of surgical intervention appears to be an important prognostic factor, however with a somehow diminished effect by novel systemic therapies. The importance of multiple lines of targeted therapies is underlined by this retrospective analysis. For patients with metastatic RCC not receiving targeted therapy the median OS was 22.6 months compared to those with one TKI 25.4 months. Patients receiving a second-line therapy (median overall survival 27.6 months) and those patients with three or more lines of therapy (43.8 months) have the greatest benefit. Also, exposure to a mTORi improves survival versus non-exposure to mTORi (63.3 vs. 22.3 months, p=0.038). In conclusion a trend towards improved survival is confirmed for an unselected population when the full variety of therapeutic options is available and can be used for the individual patient.

    OBJECTIVE—To identify survival prognostic factors and markers of morbidity among patients with systemic sclerosis (SSc).
PATIENTS AND METHODS—The study included 72 patients diagnosed with SSc. According to the extent of skin involvement, three groups of patients were established: group 1, without sclerosis and with sclerosis of fingers and neck; group 2, with sclerosis of face and distal to elbows and knees; group 3, with generalised sclerosis including the trunk. All patients were included in a study protocol to determine visceral involvement. Cumulative survival after first symptom has been estimated according to the Kaplan-Meier method. The association between a hypothetical prognostic factor and cumulative survival after first symptom was assessed by log rank test. The association between a hypothetical risk factor and the prevalence of severe morbity was assessed by the odds ratio. Multiple logistic regression models were used to identify the main predictors of severe morbidity.
RESULTS—Survival was estimated to be 85% 10 years after first SSc symptom. Survival was higher among SSc patients with skin involvement distal to elbows and knees than among the rest of patients; a forced vital capacity (FVC) on spirometry lower than 70% of expected value was associated with a shorter survival, even after adjustment for diffuse SSc. Skin involvement proximal to elbows or knees was associated with a higher prevalence of severe morbidity (OR = 46.57; p<0.001). According to a multiple logistic regression, severe morbidity was higher among patients with skin involvement proximal to knees or elbows (OR = 40.92; p<0.001) or among patients with pulmonary hypertension detected by Doppler echocardiography (OR = 23.66 p<0.001).
CONCLUSIONS—In patients with SSc the extent of skin sclerosis was found to be a determining factor on the prognosis. According to skin sclerosis extent two main subsets of SSc patients with different survival incidence and degree

    Purpose To define characteristics, treatment response, and outcomes of men with brain metastases (BM) from germ cell tumors (GCT). Patients and Methods Data from 523 men with BM from GCT were collected retrospectively from 46 centers in 13 countries by using standardized questionnaires. Clinical features were correlated with overall survival (OS) as the primary end point. Results BM were present at initial diagnosis in 228 men (group A) and at relapse in 295 men (group B). OS at 3 years (3-year OS) was superior in group A versus group B (48% v 27%; P < .001). Multiple BM and the presence of liver or bone metastasis were independent adverse prognostic factors in both groups; primary mediastinal nonseminoma (group A) and elevations of α-fetoprotein of 100 ng/mL or greater or of human chorionic gonadotropin of 5,000 U/L or greater (group B) were additional independent adverse prognostic factors. Depending on these factors, the 3-year OS ranged from 0% to 70% in group A and from 6% to 52% in group B. In group A, 99% of patients received chemotherapy; multimodality treatment or high-dose chemotherapy was not associated with statistically improved survival in multivariable analysis. In group B, only 54% of patients received chemotherapy; multimodality treatment was associated with improved survival compared with single-modality therapy (hazard ratio, 0.51; 95% CI, 0.36 to 0.73; P < .001), as was high-dose compared with conventional-dose chemotherapy (hazard ratio, 0.41; 95% CI, 0.24 to 0.70; P = .001). Conclusion Men with BM from GCT have poor OS, particularly if additional risk factors are present. High-dose chemotherapy and multimodality treatment seemed to improve survival probabilities in men with BM at relapse. PMID:26460295

    Background Intracerebral hemorrhage (ICH) is a well-known condition, but ICH restricted to the thalamus is less widely studied. We investigated the prognostic factors of thalamic ICHs. Material/Methods Seventy patients from January 2009 to November 2014 were retrospectively reviewed. Patients who demonstrated spontaneous ICH primarily affecting the thalamus on initial brain computed tomography (CT) were enrolled. Patients were categorized into 2 groups based on their Glasgow Outcome Scale (GOS) scores. Various presumptive prognostic factors were analyzed to investigate relationships between various clinical characteristics and outcomes. Results Of the enrolled patients, 39 showed a GOS of 4–5, and were categorized as the good outcome group, while another 31 patients showed a GOS of 1–3 and were categorized as the poor outcome group. Initial GCS score, calculated volume of hematoma, presence of intraventricular hemorrhage (IVH), coexisting complications, hydrocephalus, performance of external ventricular drainage, and modified Graeb’s scores of patients with IVH were significantly different between the 2 groups. In multivariate analysis, among the factors above, initial GCS score (P=0.002, Odds ratio [OR]=1.761, Confidence interval [CI]=1.223–2.536) and the existence of systemic complications (P=0.015, OR=0.059, CI=0.006–0.573) were independently associated with clinical outcomes. Calculated hematoma volume showed a borderline relationship with outcomes (P=0.079, OR=0.920, CI=0.839–1.010). Conclusions Initial GCS score and the existence of systemic complications were strong predictive factors for prognosis of thalamic ICH. Calculated hematoma volume also had predictive value for clinical outcomes. PMID:26343784

    We investigated distortion product otoacoustic emissions (DPOAE) as a prognostic factor in idiopathic sudden sensorineural hearing loss (ISSHL) patients with the time-dependent Cox proportional-hazards model. We also compared the importance of the prognostic factors that are reported in the literature. 108 patients with ISSHL were included. Both DPOAE and pure tone audiometry were performed everyday for a maximum of 7 days during admission and followed every other week or monthly after discharge. All DPOAE amplitudes were analyzed at 2f1-f2--namely 1093, 1375, 1750, 2187, 2781, 3500, 4375, and 5500 Hz. The average of two series of DPOAE intensity corrected for the noise level in eight frequencies was coded as dichotomous at > or =6 or <6 dB. We selected the most updated DPOAE at 3 days or more before the assessment of recovery into the analysis. The potential confounders including age, sex, history of vertigo at onset, history of hypertension, diabetes, coronary arterial disease, and stroke, configuration and severity of initial pure tone audiometry, the duration from onset to treatment, auditory brainstem response (ABR), vestibular evoked myogenic potential (VEMP), and plasma triglyceride and cholesterol levels, hemoglobin level, and erythrocyte sedimentation rate were collected for evaluation. The results showed that a better DPOAE amplitude was a significantly good prognostic indicator both in univariate analysis (recovery rate ratio = 3.626, 95% CI = 2.119-6.205, p < 0.0001) and multivariate analysis (recovery rate ratio = 2.94, 95% CI = 1.537-5.624, p = 0.0011). The Kaplan-Meier estimates showed that the younger age group (< or =40 years) with better initial pure tone audiometry (<65 dB) represented a better prognosis that was compatible with previous literature (log-rank test, p = 0.0297 and p = 0.0019 respectively). In the univariate analysis, normal ABR and VEMP waveforms were associated with a better prognosis (ABR: recovery rate ratio = 2.984, 95% CI = 1

  5. Prognostic factors determining the outcome of treatment in chronic hepatitis C.

    After a brief introduction in terminology and a distinction between predictors and determinants or response to therapy in chronic hepatitis C, a review of the wide literature on this topic is presented. None of the pretreatment variables or combination of them can be used as an absolute predictor of response in individual patients. Prognostic factors can help in clinical practice for informing and counseling patients of the likelihood of response. Information on pretreatment HCV RNA levels and HCV genotype can improve the cost benefit of therapy. Predictors of response should be properly evaluated in terms of positive predictive value, negative predictive value and accuracy. The strongest hitherto predictor of sustained response to any therapeutic regimen in chronic hepatitis is the clearance of HCV RNA during treatment. Recent data suggest that sequencing of several regions of the HCV genome may provide important prognostic information on the outcome of therapy. In complex and difficult to treat subsets of patients with chronic HCV infection, available data on predictors and determinants of the outcome of treatment are limited. PMID:10925467

    The relationship between alcohol drinking and the prognosis of nasopharyngeal carcinoma (NPC) is unknown. To investigate the prognostic value of alcohol drinking on NPC, this retrospective study was conducted on 1923 male NPC patients. Patients were classified as current, former and non-drinkers according to their drinking status. Furthermore, they were categorized as heavy drinkers and mild/none drinkers based on the intensity and duration of alcohol drinking. Survival outcomes were compared using Kaplan–Meier analysis and Cox proportional hazards model. We found that current drinkers had significantly lower overall survival (OS) rate (5-year OS: 70.2% vs. 76.4%, P < 0.001) and locoregional recurrence-free survival (LRFS) rate (5-year LRFS: 69.3% vs. 77.5%, P < 0.001) compared with non-drinkers. Drinking ≥14 drinks/week, and drinking ≥20 years were both independent unfavorable prognostic factors for OS (hazard ratio [HR] = 1.38, 95% confidence interval [CI] 1.05–1.81, P = 0.022; HR = 1.38, 95% CI 1.09–1.75, P = 0.007). Stratified analyses further revealed that the negative impacts of alcohol were manifested mainly among older patients and among smokers. In conclusion, alcohol drinking is a useful predictor of prognosis in male NPC patients; drinkers, especially heavy drinkers have poorer prognosis. PMID:26776301

    Background The finding of new biomarkers is needed to have a better sub-classification of primary renal tumors (RCC) as well as more reliable predictors of outcome and therapy response. In this study, we evaluated the role of circulating FGF21, an endocrine factor, as a diagnostic and prognostic biomarker for ccRCC. Materials and Methods Serum samples from healthy controls (HC), clear cell and chromophobe RCC cancer patients were obtained from the serum biobank “Biobanco Público de Muestras Séricas Oncológicas” (BPMSO) of the “Instituto de Oncología “Ángel H. Roffo”. Serum FGF21 and leptin were measured by ELISA while other metabolic markers were measured following routinely clinical procedures. Results One of our major findings was that FGF21 levels were significantly increased in ccRCC patients compared with HC. Moreover, we showed an association between the increased serum FGF21 levels and the shorter disease free survival in a cohort of 98 ccRCC patients, after adjustment for other predictors of outcome. Conclusion Our results suggest that higher FGF21 serum level is an independent prognostic biomarker, associated with worse free-disease survival. PMID:27358750

    Objective Recent studies have investigated the significance of GATA3 expression in patients with various malignant tumors. However, no previous studies have evaluated the clinicopathological importance of GATA3 expression in soft tissue sarcomas (STS) patients. Methods We evaluated GATA3 expression in 76 STS cases using immunohistochemical analysis, and statistically compared clinicopathological characteristics between GATA3-positive and GATA3-negative cases. Result GATA3-positive expression was significantly associated with a higher mitotic count (P < 0.0001). Disease-free survival (DFS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0104). Overall survival (OS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0006). GATA3-positive expression was significantly associated with shorter DFS in both univariate analysis (hazard ratio [HR], 2.719; P = 0.012) and multivariate analysis (HR, 2.711; P = 0.014). GATA3-positive expression was also significantly associated with worse OS in both univariate analysis (HR, 5.730; P = 0.0007) and multivariate analysis (HR, 5.789; P = 0.0008). Conclusion These results indicate that GATA3 is an independent prognostic factor and suggest that evaluation of GATA3 expression might enable more effective clinical follow-up using prognostic stratification of STS patients.

    The CRNDE gene seems to play an oncogenic role in cancers, though its exact function remains unknown. Here, we tried to assess its usefulness as a molecular prognostic marker in ovarian cancer. Based on results of our microarray studies, CRNDE transcripts were further analyzed by Real-Time qPCR-based profiling of their expression. The qPCR study was conducted with the use of personally designed TaqMan assays on 135 frozen tissue sections of ovarian carcinomas from patients treated with platinum compounds and either cyclophosphamide (PC, N = 32) or taxanes (TP, N = 103). Elevated levels of two different CRNDE transcripts were a negative prognostic factor; they increased the risk of death and recurrence in the group of patients treated with TP, but not PC (DNA-damaging agents only). Higher associations were found for overexpression of the short CRNDE splice variant (FJ466686): HR 6.072, 95% CI 1.814–20.32, p = 0.003 (the risk of death); HR 15.53, 95% CI 3.812–63.28, p < 0.001 (the risk of recurrence). Additionally, accumulation of the TP53 protein correlated with decreased expression of both CRNDE transcripts in tumor cells. Our results depict CRNDE as a potential marker of poor prognosis in women with ovarian carcinomas, and suggest that its significance depends on the therapeutic regimen used. PMID:26556866

    This study sought to investigate the clinical outcome and the role of postoperative radiotherapy for patients with salivary duct carcinoma (SDC) who had undergone surgery and postoperative radiotherapy. We performed a retrospective analysis of 25 SDC patients treated between 1998 and 2011 with surgery and postoperative radiotherapy. The median prescribed dose was 60 Gy (range, 49.5–61.4 Gy). The clinical target volume (CTV) was defined as the tumor bed in four patients, the tumor bed and ipsilateral neck in 14 patients, and the tumor bed and bilateral neck in six patients. Local control (LC), disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and prognostic variables were analyzed with the log-rank test. The 5-year LC, DFS and OS were 67%, 45% and 47%, respectively. Disease recurrence was found in 12 patients: seven as local, four as regional and eight as distant failure. Perineural and lymphovascular invasion was a significant prognostic factor for LC (P = 0.03). Local failure was common, and the presence of local recurrence significantly affected the OS (P < 0.05). We conclude that surgery and postoperative radiotherapy is expected to decrease the risk of local failure and contribute to good prognoses for patients with SDC. It might be advisable to have the CTV include the cranial nerves involved and the corresponding parts of the skull base in cases of pathologically positive perineural invasion. PMID:23559598

    Natural history studies have identified factors that predict evolution to multiple sclerosis or risk of disability accumulation over time. Although these studies are based on large multicentre cohorts with long follow-ups, they have limitations such as lack of standardized protocols, a retrospective data collection or lack of a systematic magnetic resonance imaging acquisition and analysis protocol, often resulting in failure to take magnetic resonance and oligoclonal bands into account as joint covariates in the prediction models. To overcome some of these limitations, the aim of our study was to identify and stratify baseline demographic, clinical, radiological and biological characteristics that might predict multiple sclerosis development and disability accumulation using a multivariate approach based on a large prospective cohort of patients with clinically isolated syndromes. From 1995 to 2013, 1058 patients with clinically isolated syndromes were included. We evaluated the influence of baseline prognostic factors on the risk for developing clinically definite multiple sclerosis, McDonald multiple sclerosis, and disability accumulation (Expanded Disability Status Scale score of 3.0) based on univariate (hazard ratio with 95% confidence intervals) and multivariate (adjusted hazard ratio with 95% confidence intervals) Cox regression models. We ultimately included 1015 patients followed for a mean of 81 (standard deviation = 57) months. Female/male ratio was 2.1. Females exhibited a similar risk of conversion to multiple sclerosis and of disability accumulation compared to males. Each younger decade at onset was associated with a greater risk of conversion to multiple sclerosis and with a protective effect on disability. Patients with optic neuritis had a lower risk of clinically definite multiple sclerosis [hazard ratio 0.6 (0.5-0.8)] and disability progression [hazard ratio 0.5 (0.3-0.8)]; however, this protective effect remained marginal only for disability

    Abstract Although microsatellite instability-high (MSI-H) colorectal cancers (CRCs) have been shown to exhibit a distinct phenotype, the clinical value of MSI-low (MSI-L) in CRC remains unclear. We designed this study to examine the clinicopathologic characteristics and oncologic implications associated with MSI-L CRCs. We retrospectively reviewed data of CRC patients from 3 tertiary referral hospitals in Korea, who underwent surgical resection between January 2003 and December 2009 and had available MSI testing results. MSI testing was performed using the pentaplex Bethesda panel. Clinicopathologic features and oncologic outcomes were compared between MSI-L and microsatellite stable (MSS) CRCs; prognostic factors for survival were also examined. Of the 3019 patients reviewed, 2621 (86.8%) were MSS, and 200 (6.6%) were MSI-L; the remaining 198 (6.6%) were MSI-H. MSI-L and MSS CRCs were comparable in terms of their clinicopathologic features, with the exception of proximal tumor location (MSI-L 30.0% vs MSS 22.1%, P = 0.024) and tumor size (MSI-L 5.2 ± 2.6 cm vs MSS 4.6 ± 2.1 cm, P = 0.001). No differences were detected in either 3-year disease-free survival (MSI-L 87.2% vs MSS 82.6%, P = 0.121) or 5-year overall survival (OS) (MSI-L 74.2% vs MSS 78.3%, P = 0.131) by univariable analysis. However, MSI-L was an independent prognostic factor for poor OS by Cox regression analysis (hazard ratio 1.358, 95% confidence interval 1.014–1.819, P = 0.040). MSI-L may be an independent prognostic factor for OS in sporadic CRCs despite their clinicopathologic similarity to MSS. Further studies investigating the significance of MSI-L in the genesis and prognosis of CRCs are needed. PMID:26683947

    Background: Through Diffusion Weighted Imaging (DWI), information related to early molecular changes, changes in the permeability of cell membranes, and early morphologic and physiologic changes such as cell swelling can be obtained. Aims: We investigated the correlation between the prognostic factors of breast cancer and apparent diffusion coefficient (ADC) in DWI sequences of malignant lesions. Study Design: Retrospective cross-sectional study. Methods: Patients who were referred to our clinic between September 2012 and September 2013, who underwent dynamic breast MRI before or after biopsy and whose biopsy results were determined as malignant, were included in our study. Before the dynamic analysis, DWI sequences were taken. ADC relationship with all prognostic factors was investigated. Pearson correlation test was used to compare the numerical data, while Spearman correlation and Fisher exact tests were used to compare the categorical data. The advanced relationships were evaluated with linear regression analysis and univariate analysis. The efficiency of the parameters was evaluated using ROC analysis. The significance level (P) was accepted as 0.05. Results: In total, 41 female patients with an average age of 49.4 years (age interval 21–77) and 44 lesions were included into the study. In the Pearson correlation test, no statistically significant difference was determined between ADC and the patient’s age and tumor size. In the Spearman correlation test, a statistically significant difference was determined between nuclear grade (NG) and ADC (r=−0.424, p=0.04); no statistically significant correlation was observed between the other prognostic factors with each other and ADC values. In the linear regression analysis, the relationship of NG with ADC was found to be more significant alone than when comparing all parameters (corrected r2=0.196, p=0.005). Further evaluations between the NG and ADC correlation were carried out with ROC analysis. A

    Students with attention-deficit/hyperactivity disorder (ADHD) experience significant academic difficulties that can lead to numerous negative academic consequences. With a focus on adverse academic outcomes, this study seeks to disentangle variance attributable to ADHD from variance attributable to salient personal and contextual covariates. Responses from 136 students with ADHD and 3,779 non-ADHD peers from 9 high schools were analyzed using logistic regression. Dependent measures included academic failure, grade repetition, school refusal, changing classes and school, school exclusion, and schoolwork noncompletion. Covariates comprised personal (e.g., sociodemographics, personality, prior achievement, specific learning disabilities, motivation) and contextual (e.g., school size, school socioeconomic status, school average achievement) factors. Findings indicated that, after accounting for personal and contextual covariates, ADHD explained significant variance in numerous adversities (schoolwork noncompletion, school suspension, school expulsion, changing schools, grade repetition). Thus, beyond the effects of numerous personal and contextual covariates, ADHD has a distinct presence in students' academic adversity. Also interesting, after accounting for other personal and contextual factors, was academic adversity with which ADHD was not associated. Findings provide direction for educational intervention targeting ADHD and associated factors found to be significant in the study.

    Peripheral T-cell lymphomas (PTCLs) are rare lymphomas with mostly poor outcome with current treatment. The addition of etoposide to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and upfront consolidation with autologous stem cell transplantation (auto-SCT) have shown promising results but have never been tested in randomized trials. As a complement to retrospective analyses of clinical trials, we aimed at analyzing prognostic factors and outcome in an unselected, population-based cohort. Through the Swedish Lymphoma Registry, we identified 755 PTCL patients diagnosed during a 10-year period. In addition to International Prognostic Index factors, male gender was associated with an adverse overall survival (OS) (hazard ratio [HR], 1.28; P = .011) and progression-free survival (PFS) (HR, 1.26; P = .014). In an intention-to-treat analysis in 252 nodal PTCL and enteropathy-associated T-cell lymphoma patients (excluding anaplastic lymphoma kinase-positive anaplastic large cell lymphoma), upfront auto-SCT was associated with a superior OS (HR, 0.58; P = .004) and PFS (HR, 0.56; P = .002) compared with patients treated without auto-SCT. The addition of etoposide to CHOP resulted in superior PFS in patients ≤60 years (HR, 0.49; P = .008). This study is the largest population-based PTCL cohort reported so far and provides important information on outcome in PTCL outside the setting of clinical trials.

    The purpose of this study was to identify variables associated with post-operative pressure sore incidence. The data were derived from a sequential, double triangular, randomised, blinded, controlled trial of the intra-operative use of a visco-elastic polymer pad conducted at two centres. Of 446 surgical patients recruited the main endpoint was assessed for 416 patients of whom 65 (15.6%) had a post-operative pressure sore. Analysis determined that the probability of a patient developing a pressure sore was associated with increased number of hypotensive episodes and mean core temperature during surgery, and reduced mobility Day 1 post-operatively. The development of a probability equation illustrates the future potential of prognostic factor research in the development of risk assessment tools and their application within clinical settings.

    Clinical and quality of life (QL) variables from an EORTC clinical trial of first line chemotherapy in advanced breast cancer were used in a prognostic factor analysis of survival and response to chemotherapy. For response, different final multivariate models were obtained from forward and backward selection methods, suggesting a disconcerting instability. Quality of life was measured using the EORTC QLQ-C30 questionnaire completed by patients. Subscales on the questionnaire are known to be highly correlated, and therefore it was hypothesized that multicollinearity contributed to model instability. A correlation matrix indicated that global QL was highly correlated with 7 out of 11 variables. In a first attempt to explore multicollinearity, we used global QL as dependent variable in a regression model with other QL subscales as predictors. Afterwards, standard diagnostic tests for multicollinearity were performed. An exploratory principal components analysis and factor analysis of the QL subscales identified at most three important components and indicated that inclusion of global QL made minimal difference to the loadings on each component, suggesting that it is redundant in the model. In a second approach, we advocate a bootstrap technique to assess the stability of the models. Based on these analyses and since global QL exacerbates problems of multicollinearity, we therefore recommend that global QL be excluded from prognostic factor analyses using the QLQ-C30. The prognostic factor analysis was rerun without global QL in the model, and selected the same significant prognostic factors as before.

    Purpose: To provide further understanding regarding outcome and prognostic factors of endometrial stromal tumors (EST). Methods and Materials: A retrospective analysis was performed on the records of 59 women diagnosed with EST and treated with curative intent between 1983 and 2007 in the framework of the Rare Cancer Network. Results: Endometrial stromal sarcomas (ESS) were found in 44% and undifferentiated ESS (UES) in 49% of the cases. In 7% the grading was unclear. Of the total number of patients, 33 had Stage I, 4 Stage II, 20 Stage III, and 1 presented with Stage IVB disease. Adjuvant chemotherapy was administered to 12 patients, all with UES. External-beam radiotherapy (RT) was administered postoperatively to 48 women. The median follow-up was 41.4 months. The 5-year overall survival (OS) rate was 96.2% and 64.8% for ESS and UES, respectively, with a corresponding 5-year disease-free survival (DFS) rate of 49.4% and 43.4%, respectively. On multivariate analysis, adjuvant RT was an independent prognostic factor for OS (p = 0.007) and DFS (p = 0.013). Locoregional control, DFS, and OS were significantly associated with age ({<=}60 vs. >60 years), grade (ESS vs. UES), and International Federation of Gynecology and Obstetrics stage (I-II vs. III-IV). Positive lymph node staging had an impact on OS (p < 0.001). Conclusion: The prognosis of ESS differed from that of UES. Endometrial stromal sarcomas had an excellent 5-year OS, whereas the OS in UES was rather low. However, half of ESS patients had a relapse. For this reason, adjuvant treatment such as RT should be considered even in low-grade tumors. Multicenter randomized studies are still warranted to establish clear guidelines.

    Purpose: To evaluate the therapeutic effect of percutaneous transhepatic biliary drainage (PTBD) in patients with obstructive jaundice caused by biliary involvement of hepatocellular carcinomas (HCC) and to determine the prognostic factors. Methods: We retrospectively analyzed the data of 22 consecutive patients (M:F = 20:2, mean age 52.8 years).Inclusion criteria were the patient having obstructive jaundice caused by HCC that invaded the bile ducts and having at least 4 weeks of follow-up data after the PTBD. We defined 'good response' and 'poor response' as whether the level of total bilirubin decreased more than 50% in 4 weeks or not. Total bilirubin level (T-bil),Child-Pugh score and the location of biliary obstruction for the two groups were compared. In addition, the interval between clinical onset of jaundice and PTBD, the degree of parenchymal atrophy and the size of the primary tumor were compared. Results: Of the 22 patients, 13 (59.1%) showed good response. T-bil was significantly lower in the good response group than in the poor (14.2 {+-} 6 mg/dlvs 25.9 {+-} 13.8 mg/dl, p = .017). In the five patients with T-bil <10 mg/dl, four (80%) showed good response,while in nine patients with T-bil > 20 mg/dl, only three (33%)showed good response. Although statistically not significant, patients with Child score <10 showed better results [good response rate of 66.7% (12/18)] than patients with Child score ?10 [good response rate of 25% (1/4)]. Involvement of secondary confluence of the bile duct also served as a poor prognostic factor (p =0.235). The interval between clinical onset of jaundice and PTBD, the presence of parenchymal atrophy and the size of the tumor did not show significant effect. Conclusion: Early and effective biliary drainage might be necessary in this group of patients with limited hepatic function.

    Sarcopenia reportedly predicts poor outcomes in elderly patients with diffuse large B-cell lymphoma (DLBCL). However, because previous studies only involved elderly patients, it is difficult to generalize these results to all patients with DLBCL. We retrospectively analyzed 207 patients with DLBCL who received the R-CHOP or R-THP-COP regimen between June 2004 and May 2014. Sarcopenia was measured by the analysis of CT images at the L3 level before treatment. The surface of muscular tissues was selected according to the CT Hounsfield unit. This value was normalized for stature in order to calculate the L3 skeletal muscle index (L3 SMI, cm(2)/m(2)). Median age at diagnosis in the 121 males and 86 females was 67 years (range, 19-86 years). The sex-specific cutoffs for the L3 SMI were determined by receiver operator curve (ROC) analysis. Sarcopenic patients were older than non-sarcopenic patients, with a median age of 70 and 65 years, respectively (p < 0.001). Other International Prognostic Index factors were not significantly different when comparing sarcopenic and non-sarcopenic patients. With a median follow-up of 50.4 months, the 3-year overall survival (OS) was 70 % in the sarcopenic group and 85 % in the non-sarcopenic group (p = 0.0260). In a subgroup analysis by gender, there was a significant difference in the OS when comparing sarcopenic and non-sarcopenic patients in males but not in females (p = 0.0003, p = 0.4440, respectively). Sarcopenia is an independent prognostic factor in male patients with DLBCL. PMID:26385388

    Although elevated resting heart rate (RHR) has been shown to be associated with mortality in the general population and patients with certain diseases, no study has examined this association in patients with breast cancer. A total of 4786 patients with stage I-III breast cancer were retrospectively selected from the Severance hospital breast cancer registry in Seoul, Korea. RHR was measured at baseline and the mean follow-up time for all patients was 5.0 ± 2.5 years. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated using Cox regression models. After adjustment for prognostic factors, patients in the highest quintile of RHR (≥85 beat per minute (bpm)) had a significantly higher risk of all-cause mortality (HR: 1.57; 95 %CI 1.05-2.35), breast cancer-specific mortality (HR: 1.69; 95 %CI 1.07-2.68), and cancer recurrence (HR: 1.49; 95 %CI 0.99-2.25), compared to those in the lowest quintile (≤67 bpm). Moreover, every 10 bpm increase in RHR was associated with 15, 22, and 6 % increased risk of all-cause mortality, breast cancer-specific mortality, and cancer recurrence, respectively. However, the association between RHR and cancer recurrence was not statistically significant (p = 0.26). Elevated RHR was associated with an increased risk of mortality in patients with breast cancer. The findings from this study suggest that RHR may be used as a prognostic factor for patients with breast cancer in clinical settings. PMID:27544225

    Purpose: The aim of this study was to evaluate the results of keloidectomy and strontium 90 brachytherapy in the prevention of keloid recurrence following excision and to identify outcome and the prognostic factors that predict keloid recurrence after irradiation. Methods and Materials: Data of 612 patients with 892 keloids treated between 1992 and 2006 were evaluated retrospectively. Brachytherapy was performed using a Sr-90Y surface applicator. Total dose was 20 Gy in 10 fractions. Results: With a median follow-up of 61 months, the overall recurrence-free response rate for all keloids was 87.6%. Multivariate analysis revealed the following prognostic factors for recurrence: keloid size > 5 cm (p < 0.0001), burn scars as the keloid etiology (p < 0.0001), and previous treatment (p < 0.0001). Outcome was not found to be significantly related to the interval between surgery and radiotherapy, sex, or age. Pruritus and skin reddening were the most common symptoms of keloids, but all signs and symptoms abated with time after treatment. Cosmetic results from the keloid treatment were considered good or excellent in 70.6% of the patients. Conclusion: Our study findings show that excision plus Sr-90 brachytherapy is effective in the eradication of keloids. Sr-90 radiotherapy (20 Gy in 10 fractions) achieved a similar local control rate, as have higher doses per fraction in other series. It also resulted in a good cosmetic rate and relief of symptoms. Our data further suggest that the initiation of postoperative irradiation within hours of surgical excision is not important to therapeutic outcome.

    Objectives: Laser cordectomy is very popular nowadays and become one of the treatments of choice for early glottis carcinoma. Transoral laser microsurgery has many advantages comparing conventional open surgery or radiation therapy. In this study, we examined the oncologic results of laser cordectomy for early glottic cancer and analyzed the prognostic impact on the survival of the several tumor-related and treatment-related factors. Methods: Patients who were diagnosed as early glottic squamous cell carcinoma, treated by laser cordectomy with curative intent were analyzed. Patients with preivous radiation therapy were included. From June 1988 to March 2005, 202 patients from five hospitals were analyzed (174 T1, 28 T2). Results: Five-year overall survival and disease-free survival were 98.4% and 84.9%. Twenty two patients developed local recurrence. Total laryngectomy was done in 6 patients and laryngeal preservation rate was 97%. Recurrence was higher in the patients with anterior commissure involvement (9/39) than without anterior commissure involvement (13/163). Recurrence was higher in T1b (4/15) than T1a (13/159). Previous radiation was also highly related to the recurrence (7/20 vs 15/182). Twenty patients with local recurrence after radiation therapy were treated by salvage laser cordectomy. Of them, 7 patients developed local recurrence and 5 year disease-free survival was 57%. Complication was rare with one case of hemorrhage. Tracheotomy was not necessary in all patients. Conclusions: Laser cordectomy for early glottic carcinoma showed high survival, laryngeal preservation rate and low complication rate. The prognostic factors were anterior commissure involvement, both vocal fold involvement and previous radiotherapy.

    Being overweight is recognised as a significant risk factor for several morbidities; however, the experience of the dentistry faculties focusing on this population is still low. The aim of the present study was to determine the occurrence of adverse events during removal of impacted lower third molars in overweight patients. A prospective cohort study was carried out involving overweight patients subjected to surgical removal of impacted lower third molar as part of a line of research on third molar surgery. Predictor variables indicative of the occurrence of adverse events during surgery were classified by their demographic, clinical, radiographic, and surgical aspects. Descriptive and bivariate statistics were computed. In total, 140 patients fulfilled the eligibility criteria, and 280 surgeries were performed. Patients' mean age was 25.1 ± 2.2 years, and the proportion of women to men was 3 : 1. Eight different adverse events during surgery were recorded. These events occurred in approximately 29.3% of cases and were significantly associated with predictor variables (P < 0.05). Excess weight is recognised as a risk factor for the high rate of adverse events in impacted third molar surgery. The study suggests that overweight patients are highly likely to experience morbidities. PMID:25548786

    Background: Peritumoral vascular invasion (PVI) may assist in assigning optimal adjuvant systemic therapy for women with early breast cancer. Patients and methods: Patients participated in two International Breast Cancer Study Group randomized trials testing chemoendocrine adjuvant therapies in premenopausal (trial VIII) or postmenopausal (trial IX) node-negative breast cancer. PVI was assessed by institutional pathologists and/or central review on hematoxylin–eosin-stained slides in 99% of patients (analysis cohort 2754 patients, median follow-up >9 years). Results: PVI, present in 23% of the tumors, was associated with higher grade tumors and larger tumor size (trial IX only). Presence of PVI increased locoregional and distant recurrence and was significantly associated with poorer disease-free survival. The adverse prognostic impact of PVI in trial VIII was limited to premenopausal patients with endocrine-responsive tumors randomized to therapies not containing goserelin, and conversely the beneficial effect of goserelin was limited to patients whose tumors showed PVI. In trial IX, all patients received tamoxifen: the adverse prognostic impact of PVI was limited to patients with receptor-negative tumors regardless of chemotherapy. Conclusion: Adequate endocrine adjuvant therapy appears to abrogate the adverse impact of PVI in node-negative disease, while PVI may identify patients who will benefit particularly from adjuvant therapy.

    Background We assessed the impact on survival of angiogenesis and inflammation-related factors, particularly LDH serum levels, platelet, neutrophil and lymphocyte counts, and neutrophil-to-lymphocyte ratio (NLR), in metastatic colorectal cancer patients receiving regorafenib monotherapy. Methods LDH serum levels, neutrophil, lymphocyte and platelet counts were collected at the start of regorafenib monotherapy. Cut-off values were calculated by ROC curve analysis. Survival analyses were performed by Kaplan-Meier method, and multivariate analysis by Cox method. Results A total of 208 patients were eligible for analysis. Among factors who were related with worse overall survival and who maintained their role at the multivariate analysis, high platelet count (Exp(b):1.4963, 95% CI:1.0130–2.2103, p = 0.0439) and high neutrophil/lymphocyte ratio (Exp(b):1.6963, 95% CI:1.0757–2.6751, p = 0.0237) were those who more deeply were related to worse overall survival. High lymphocyte count (Exp(b):0.4527, 95% CI:0.2801–0.7316, p = 0.0013) was correlated with improved overall survival. Conclusions High neutrophil, high platelet, low lymphocyte count and/or high NLR may represent negative prognostic factors in patients receiving regorafenib monotherapy. It is advisable that these factors are taken into account in the design of subsequent trials in colorectal cancer patients receiving this drug. PMID:26334693

    Background Aberrant expression of cancer-testis antigens (CTA) in breast carcinoma tissue, and its natural expression in the testis, the tissue away from the immune system, makes them good candidates for cancer immunotherapy and vaccines designing. Objectives The aim of this study was to assess the expression of a CTA (MAGE-1) in invasive breast cancer and its correlation with prognostic factors. Methods Paraffin blocks of breast cancer tissues from 113 patients operated in 2011 - 2013 were stained for MAGE-1expression by immunohistochemistry (IHC). The associations of MAGE-1 expression with known prognostic factors were assessed by statistical analysis using SPSS 16. Results MAGE-1 expression was found in cancer cell cytoplasms of 30.1% of patients, with different degrees of intensity, (23.9% moderate and 6.2% strong). Nuclear staining turned positive in 31.8%, stratified from moderate in 26.5%to to strong in 5.3%. There was a significant association between the number of lymph nodes involved and both nuclear (P = 0.042) and cytoplasmic (P = 0.003) MAGE-1 expression. There was also a significant correlation between the nuclear expression of MAGE-1 and tumor size (P = 0.018). Cytoplasmic expression of MAGE-1 increased with increasing pathologic grade of tumors although the association was not statistically significant (P = 0.119). Conclusions CTA MAGE-1 has significant association with some prognostic factors in breast cancer and may have the role of a prognostic factor. PMID:27761208

    Mantle cell lymphoma (MCL) is usually an aggressive disease. However, a few patients do have an "indolent" evolution (iMCL) defined by a long survival time without intensive therapy. Many studies highlight the prognostic role of additional genetic abnormalities, but these abnormalities are not routinely tested for and do not yet influence the treatment decision. We aimed to evaluate the prognostic impact of these additional abnormalities detected by conventional cytogenetic testing, as well as their relationships with the clinical characteristics and their value in identifying iMCL. All consecutive MCL cases diagnosed between 1995 and 2011 at four institutions were retrospectively selected on the basis of an informative karyotype with a t(11;14) translocation at the time of diagnosis. A total of 125 patients were included and followed for an actual median time of 35 months. The median overall survival (OS) and survival without treatment (TFS) were 73.7 and 1.3 months, respectively. In multivariable Cox models, a high mantle cell lymphoma international prognostic index score, a complex karyotype, and blastoid morphology were independently associated with a shortened OS. Spleen enlargement, nodal presentation, extra-hematological involvement, and complex karyotypes were associated with shorter TFS. A score based on these factors allowed for the identification of "indolent" patients (median TFS 107 months) from other patients (median TFS: 1 month). In conclusion, in this multicentric cohort of MCL patients, a complex karyotype was associated with a shorter survival time and allowed for the identification of iMCL at the time of diagnosis.

    The appropriate surgical therapeutic options for either localized or more advanced disease in patients with gastrointestinal leiomyosarcomas remain unclear. A staging classification for this disease has not been adopted nor risk factors identifying patients at risk for recurrence defined. To address these issues, this study evaluated the influence of various clinicopathologic variables on overall and disease-free survival. In an univariate analysis of overall survival involving 191 patients, the Cox proportional hazards model identified four factors that were associated with a significantly better outcome: complete resection without tumor rupture (p less than 0.001), localized lesions (p less than 0.001), low grade of tumor (p = 0.02), and tumors smaller than 5 cm (p = 0.03). When interactive effects of these factors were taken into account, however, type of resection of the tumor was selected as the only significant prognostic factor in a multivariate analysis. Complete resection without tumor rupture improved overall survival of patients with localized disease (median, 46 months) as well as those with contiguous organ invasion (median, 36 months) or peritoneal implants (median, 36 months). In contrast, patients with incomplete resections survived for a median of 21 months. Patients with tumor rupture, despite removal of all gross disease, behaved similarly to those with incomplete resections; median survival was only 17 months. For disease-free survival, important determinants selected from a multivariate analysis were tumor rupture (p = 0.002), contiguous organ invasion (p = 0.02) and high tumor grade (p = 0.02). A staging classification incorporating these prognostic factors of significance was evaluated using a TGM system: T1 (less than 5 cm), T2 (greater than or equal to 5 cm), T3 (contiguous organ invasion or peritoneal implants), T4 (tumor rupture); G: G1 (low grade), G2 (high grade); M: M0 (no metastases), M1 (metastases present).

    Thirteen male-to-female transsexuals were investigated 6 to 25 years after surgery. Thirty-five prognostic items were compared with each of three outcome variables. Traumatic loss of both parents in infancy was connected with repentance at follow-up. A childhood family of an overprotective mother and a distant father, on the other hand, was prognostically favourable. Contrary to most previous reports, high sexual activity and bisexual experience was associated with fair sexual adjustment and with non-repentance after sex change. The repenting individuals, on the other hand, had been a-sexual or hyposexual before surgery. Completed military service, a history of typically masculine, hard jobs, and a comparatively late (more than 30 years of age) first request for surgery, were found to be negative prognostic factors in sex-reassignment evaluations. The phenomenon of ambivalence or hesitance during the trial period is discussed. Both too much and too little ambivalence may suggest a poor prognosis. PMID:3591409

    Objective To understand why children exposed to adverse psychosocial experiences are at elevated risk for age-related disease, such as cardiovascular disease, by testing whether adverse childhood experiences predict enduring abnormalities in stress-sensitive biological systems, namely, the nervous, immune, and endocrine/metabolic systems. Design A 32-year prospective longitudinal study of a representative birth cohort. Setting New Zealand. Participants A total of 1037 members of the Dunedin Multidisciplinary Health and Development Study. Main Exposures During their first decade of life, study members were assessed for exposure to 3 adverse psychosocial experiences: socioeconomic disadvantage, maltreatment, and social isolation. Main Outcome Measures At age 32 years, study members were assessed for the presence of 3 age-related-disease risks: major depression, high inflammation levels (high-sensitivity C-reactive protein level >3 mg/L), and the clustering of metabolic risk biomarkers (overweight, high blood pressure, high total cholesterol, low high-density lipoprotein cholesterol, high glycated hemoglobin, and low maximum oxygen consumption levels. Results Children exposed to adverse psychosocial experiences were at elevated risk of depression, high inflammation levels, and clustering of metabolic risk markers. Children who had experienced socioeconomic disadvantage (incidence rate ratio, 1.89; 95% confidence interval, 1.36–2.62), maltreatment (1.81; 1.38–2.38), or social isolation (1.87; 1.38–2.51) had elevated age-related-disease risks in adulthood. The effects of adverse childhood experiences on age-related-disease risks in adulthood were nonredundant, cumulative, and independent of the influence of established developmental and concurrent risk factors. Conclusions Children exposed to adverse psychosocial experiences have enduring emotional, immune, and metabolic abnormalities that contribute to explaining their elevated risk for age-related disease.

    Radioactive iodine-131 (RAI) has been reported to be associated with a high incidence of development or exacerbation of Graves` ophthalmopathy (GO). This is thought to be associated with a surge of autoantibodies after RAI therapy. The role of methimazole (MMI), which possesses immunomodulatory action, in the prevention of GO was explored by studying 114 patients with Graves` disease. They were assigned randomly to receive either RAI alone or adjunctive antithyroid drugs, which consisted of MMI and L-T{sub 4} as a block-replacement therapy for 12 months and were followed for 2 yr. Thirty-five patients (30.7%) had GO at presentation. Twenty-one (18%) patients developed new GO, and six had worsening of preexisting GO. The development of hypothyroidism (P < 0.01) and an elevation of TSH (P < 0.05) were associated with increased risk of development or exacerbation of GO. The chance of development or exacerbation of GO is higher in those with no ophthalmopathy than in those with preexisting GO at presentation (P = 0.002). The incidence of development or exacerbation of GO was similar in the two treatment groups (RAI, 22.8%; adjunctive antithyroid drugs, 23.7%; P = NS). MMI was able to suppress the surge of TSH receptor antibody (TRAB) after RAI, but a surge in TRAB was not of prognostic significance for the development of GO after RAI. Patients who developed or had exacerbation of GO actually had lower TRAB at presentation (P = 0.02). The authors conclude that hypothyroidism with elevated TSH is an important adverse factor for the development or exacerbation of GO, and MMI was unable to prevent the development or exacerbation of GO after RAI. 35 refs., 4 tabs.

    Background: Pediatric glioblastoma (pGBM) patients are underrepresented in major trials for this disease. We aimed to explore the outcome of pGBM patients treated with concurrent and adjuvant temozolomide (TMZ). Materials and Methods: 23 patients of pGBM treated from 2004 to 2010 were included in this retrospective analysis. Adjuvant therapy included conformal radiation 60 gray at 2 gray/fraction daily over 6 weeks with concurrent TMZ 75 mg/m2 followed by six cycles of adjuvant TMZ 150-200 mg/m2 (day 1-5) every 4 weeks. Kaplan-Meier estimates of overall survival (OS) were determined. Univariate analysis with log-rank test was used to determine the impact of prognostic variables on survival. Results: Median age at presentation was 11.5 years (range: 7-19 years) and M:F ratio was 15:8. All patients underwent maximal safe surgical resection; 13 gross total resection and 10 sub-total resection. At a median follow-up of 18 months (range: 2.1-126 months), the estimated median OS was 41.9 months. The estimated median OS for patients receiving only concurrent TMZ was 8 months while that for patients receiving concurrent and adjuvant TMZ was 41.9 months (P = 0.081). Estimated median OS for patients who did not complete six cycles of adjuvant TMZ was 9.5 months versus not reached for those who completed at least six cycles (P = 0.0005). Other prognostic factors did not correlate with survival. Conclusions: Our study shows the benefit of TMZ for pGBM patients. Both concurrent and adjuvant TMZ seem to be important for superior OS in this group of patients. PMID:26157286

    Purpose Lymph node (LN) metastasis is the best prognostic indicator in non-distant metastatic advanced gastric cancer. This study aimed to assess the prognostic value of various clinicopathologic factors in node-negative advanced gastric cancer. Materials and Methods We retrospectively analyzed the clinical records of 254 patients with primary node-negative stage T2~4 gastric cancer. These patients were selected from a pool of 1,890 patients who underwent radical resection at Memorial Jin-Pok Kim Korea Gastric Cancer Center, Inje University Seoul Paik Hospital between 1998 and 2008. Results Of the 254 patients, 128 patients (50.4%), 88 patients (34.6%), 37 patients (14.6%), and 1 patient (0.4%) had T2, T3, T4a, and T4b tumors, respectively. In a univariate analysis, operation type, T-stage, venous invasion, tumor size, and less than 15 LNs significantly correlated with tumor recurrence and cumulative overall survival. In a multivariate logistic regression analysis, tumor size, venous invasion, and less than 15 LNs significantly and independently correlated with recurrence. In a multivariate Cox proportional hazards analysis, tumor size (hazard ratio [HR]: 2.926; 95% confidence interval [CI]: 1.173~7.300; P=0.021), venous invasion (HR: 3.985; 95% CI: 1.401~11.338; P=0.010), and less than 15 LNs (HR: 0.092; 95% CI: 0.029~0.290; P<0.001) significantly correlated with overall survival. Conclusions Node-negative gastric cancers recurred in 8.3% of the patients in our study. Tumor size, venous invasion, and less than 15 LNs reliably predicted recurrence as well as survival. Aggressive postoperative treatments and timely follow-ups should be considered in cases with these characteristics. PMID:27752393

    Objective The increasing incidence of thyroid nodules demands identification of risk factors for malignant disease. Several studies suggested the association of higher TSH levels with cancer, but influence of 25-hydroxyvitamin D (25OHD) is controversial. This study aimed to identify the relationship of thyroid cancer with higher TSH levels and hypovitaminosis D and to evaluate their influence on prognostic characteristics of papillary thyroid carcinomas (PTC). Methods We retrospectively evaluated 433 patients submitted to thyroidectomy for thyroid nodules. Patients were categorized according to quartiles of TSH and 25OHD levels. Clinicopathological features were analyzed. Results Subjects with thyroid carcinomas were more frequently male and younger compared to those with benign disease. Their median TSH levels were higher and adjusted odds-ratio (OR) for cancer in the highest-quartile of TSH (> 2.4 mUI/mL) was 2.36 (1.36–4.09). Although vitamin D deficiency/insufficiency was prevalent in our cohort (84%), no significant differences in 25OHD levels or quartile distribution were observed between benign and malignant cases. Among 187 patients with PTC, analyses of prognostic features revealed increased risk of lymph nodes metastases for subjects with highest-quartile TSH levels (OR = 3.7, p = 0.029). Decreased 25OHD levels were not overtly associated with poor prognosis in PTC. Conclusions In this cross-sectional cohort, higher TSH levels increased the risk of cancer in thyroid nodules and influenced its prognosis, particularly favoring lymph nodes metastases. On the other hand, no association was found between 25OHD levels and thyroid carcinoma risk or prognosis, suggesting that serum 25OHD determination may not contribute to risk assessment workup of thyroid nodules.

    The aim of this study was to elucidate the role of treatment modalities in primary spinal anaplastic ependymomas (PSAE) and identify promising prognostic factors. PSAE are rare tumors of the central nervous system with poorly understood clinical characteristics and treatment outcomes. We reviewed the literature in PubMed, Web of Science and Scopus databases to identify patients with PSAE. Multivariate Cox proportional hazards analysis and univariate Kaplan-Meier analysis were performed on the PSAE patients and overall survival (OS) and progression-free survival (PFS) were assessed to evaluate the clinical outcomes. Of the 40 patients with PSAE, the tumors were mostly intramedullary (n=19; 47.5%) and frequently involved the thoracic cord (n=25; 62.5%). Eighteen patients suffered recurrence during the follow-up with a median PFS of 24 months. The 1, 2, and 5year OS rates of the PSAE patients were 91.5%, 82.1%, and 63.1%, respectively. Gross total resection (GTR) was independently associated with prolonged PFS (hazard ratio [HR] 0.11; p=0.004) and OS (HR 0.11; p=0.003) in the multivariate analysis. Adjuvant radiotherapy also conferred improved PFS (HR 0.15; p=0.008) and OS (HR 0.16; p=0.022). Age, sex, tumor location and chemotherapy did not influence the outcomes in this group. The results of our study suggest that GTR and adjuvant radiotherapy are strong prognostic indicators in patients with PSAE and the role of chemotherapy is yet to be defined. PMID:25769252

    The correlation between the histological features and clinical outcome remains poor in pediatric intracranial ependymomas. We performed a retrospective study of a group of 31 patients (diagnosed from 1985 to 1995) to assess prognostic implications of the current grading system, of histological and immunohistochemical features, and of ploidy status estimated by flow cytometry. Immunoexpression of a broad spectrum of antigens was evaluated, including MIB-1, topoisomerase-IIalpha, cyclin D1, glial and epithelial proteins (GFAP, EMA, cytokeratins), molecules involved in controlling apoptosis (bcl-2, caspase-3/CPP32), and p53 oncoprotein. Univariate and multivariate statistical analyses were performed to evaluate the influence of each variable on both the progression free survival (PFS) and the overall survival (OS) with at least 7-year follow up. Although we showed a significant correlation between histological grade and prognosis, the current grading system failed in predicting outcome in nearly one third of individual cases. Problems with interpathologist reproducibility were also demonstrated. The extent of surgical resection was the only clinical factor that was associated with survival. Both the PFS and the OS were significantly decreased for the following pathological variables: increased cellularity (>300 nuclei per HPF), mitotic activity of >7 per 10 HPF, increased MIB-1 labeling index (LI), topoisomerase-IIalpha LI, S-phase fraction, and p53 and bcl-2 positivity. Increased cyclin D1 LI was demonstrated to have only a marginally significant impact on PFS. A flow chart modeling was further performed to formulate a scheme for discriminating of prognostic subgroups. Based on that, p53 immunopositivity and/or MIB-1 LI of >5% (after subtotal resection) or MIB-1 LI of >15% (after complete resection) were the strongest indicators of the tumor's aggressive behavior and of a poor prognosis of the disease. Foci of hypercellularity should be specifically looked for in

    We aimed to compare the clinicopathological features, treatment strategies and clinical outcomes of breast sarcomas (BS) and malignant phyllodes tumours (MPT), and determine their prognostic factors. Cases of BS and MPT diagnosed at the Department of Pathology, Singapore General Hospital from January 1991 to December 2014 were derived from department files. Clinicopathological features, treatment strategies and survivals of patients with BS and MPT were compared. Prognostic indicators for BS and MPT were identified. BS and MPT were comparable in all except one of their clinicopathological features. A significantly higher proportion of BS patients had a history of previous breast carcinoma and thus radiation to the chest as compared to the MPT group (17.6 vs 0 %, P = 0.018). There was no significant difference in survival outcomes between BS and MPT. The 5-year disease-free survivals (DFS) for BS and MPT were 59.1 and 57.4 % respectively (P = 0.816), while the 5-year overall survivals (OS) for BS and MPT were 86.5 and 78.5 % respectively (P = 0.792). Combining both groups of tumours, univariate analysis showed that DFS was significantly affected by multifocality (P = 0.019), histological subtype (P = 0.014), presence of malignant heterologous elements (P < 0.001) and margin status (P = 0.023). Margin status was the only parameter which had a significant impact on OS (P = 0.040). Multivariate analysis confirmed the above findings. BS and MPT are rare entities with remarkable heterogeneity. They share similar clinicopathological features and outcomes, provoking thoughts on their biological relationship and clinical significance of pathologic distinction. PMID:27541020

    AIM: To investigate the expression of endocan in tumour vessels and the relationships between endocan and the expression of vascular endothelial growth factor (VEGF) and prognosis in gastric cancer. METHODS: This study included 142 patients with confirmed gastric cancer in a single cancer centre between 2008 and 2009. Clinicopathologic features were determined, and an immunohistochemical analysis of endocan-expressing microvessel density (MVD) (endocan-MVD), VEGF and vascular endothelial growth factor receptor 2 (VEGFR2) was performed. Potential relationships between endocan-MVD and clinicopathological variables were assessed using a Student’s t-test or an analysis of variance test. Spearman’s rank correlation was applied to evaluate the relationship between endocan-MVD and the expression of VEGF/VEGFR2. Long-term survival of these patients was analysed using univariate and multivariate analyses. RESULTS: Positive staining of endocan was observed in most of the gastric cancer tissues (108/142) and in fewer of the normal gastric tissues. Endocan-MVD was not associated with gender or histological type (P > 0.05), while endocan-MVD was associated with tumour size, Borrmann type, tumour differentiation, tumour invasion, lymph node metastasis and TNM stage (P < 0.05). According to the Spearman’s rank correlation analysis, endocan-MVD had a positive correlation with VEGF (r = 0.167, P = 0.047) and VEGFR2 (r = 0.410, P = 0.000). The univariate analysis with a log-rank test indicated that the patients with a high level of endocan-MVD had a significantly poorer overall survival rate than those with a low level of endocan-MVD (17.9% vs 64.0%, P = 0.000). The multivariate analysis showed that a high level of endocan-MVD was a valuable prognostic factor. CONCLUSION: Endocan-MVD significantly correlates with the expression of VEGF and VEGFR2 and is a valuable prognostic factor for survival in human gastric cancer. PMID:27340359

    Transforming growth factor alpha (TGF alpha) and Transforming growth factor beta-1 (TGF-beta 1) are growth regulatory for breast cancer cell lines in vitro and several studies have suggested that levels of the receptor for TGF alpha, the epidermal growth factor (EGFR) in tumour biopsies predict relapse and survival. We have examined the prognostic significance of TGF alpha, TGF-beta 1 and EGFR mRNA expression in a series of patients with primary breast cancer with a median follow up period of 60 months. In 167 patients the expression of TGF-beta 1 was inversely correlated with node status (P = 0.065) but not ER status, tumour size or menopausal status. Patients with high levels of TGF-beta 1 had a longer disease free interval with a significantly longer probability of survival at 80 months although the overall relapse free survival was not increased. EGFR mRNA expression was measured in 106 patients and was inversely correlated with ER status (P = 0.018). EGFR levels did not predict for early relapse or survival. TGF alpha mRNA levels were measured in 104 patients, no correlation was seen tumour size, node status, Er status, or clinical outcome. PMID:8390290

    The relevance of cell proliferation rate--defined as the 3H-thymidine labeling index (3H-dT LI)--in predicting response to treatment (complete remission, CR), freedom from progression (FFP) and overall survival (OS) was evaluated in 86 patients with diffuse large-cell lymphoma (DLCL). The biologic variable was not associated with most of the established clinical factors, such as gender and age of the patient, performance status, B symptoms, tumor bulk, or extranodal disease, but was directly related to stage. 3H-dT LI significantly predicted short- and long-term clinical outcome. In fact, more patients with slowly proliferating DLCL reached CR and had longer median FFP and OS than patients with rapidly proliferating DLCL. Multiple-regression analysis to evaluate the relative contribution of the different biologic and clinical variables in predicting CR, FFP and OS showed that 3H-dT LI and Ann Arbor stage were the only 2 stable factors, which retained their prognostic significance even in the presence of other conventional factors, and that 3H-dT LI was the most powerful as an indicator of risk of death in DLCL patients.

    Latino children represent a significant proportion of all US children, and asthma is the most common chronic illness affecting them. Previous research has revealed surprising differences in health among Latino children with asthma of varying countries of family origin. For instance, Puerto Rican children have a higher prevalence of asthma than Mexican American or Cuban American children. In addition, there are important differences in family structure and socioeconomic status among these Latino populations: Cuban Americans have higher levels of education and family income than Mexican-Americans and Puerto Ricans; mainland Puerto Rican children have the highest proportion of households led by a single mother. Our review of past research documents differences in asthma outcomes among Latino children and identifies the possible genetic, environmental, and health care factors associated with these differences. Based on this review, we propose research studies designed to differentiate between mutable and immutable risk and prognostic factors. We also propose that the sociocultural milieus of Latino subgroups of different ethnic and geographic origin are associated with varying patterns of risk factors that in turn lead to different morbidity patterns. Our analysis provides a blue-print for future research, policy development, and the evaluation of multifactorial interventions involving the collaboration of multiple social sectors, such as health care, public health, education, and public and private agencies.

    Objective: The objective of this prospective cohort study was to analyse the characteristics of severe Traumatic Brain Injury (TBI) in a regional trauma centre Hospital Kuala Lumpur (HKL) along with its impact of various prognostic factors post Decompressive Craniectomy (DC). Materials and Methods: Duration of the study was of 13 months in HKL. 110 consecutive patients undergoing DC and remained in our centre were recruited. They were then analysed categorically with standard analytical software. Results: Age group have highest range between 12-30 category with male preponderance. Common mechanism of injury was motor vehicle accident involving motorcyclist. Univariate analysis showed statistically significant in referral area (P = 0.006). In clinical evaluation statistically significant was the motor score (P = 0.040), pupillary state (P = 0.010), blood pressure stability (P = 0.013) and evidence of Diabetes Insipidus (P < 0.001). In biochemical status the significant statistics included evidence of coagulopathy (P < 0.001), evidence of acidosis (P = 0.003) and evidence of hypoxia (P = 0.030). In Radiological sector, significant univariate analysis proved in location of the subdural clot (P < 0.010), location of the contusion (P = 0.045), site of existence of both type of clots (P = 0.031) and the evidence of edema (P = 0.041). The timing of injury was noted to be significant as well (P = 0.061). In the post operative care was, there were significance in the overall stability in intensive care (P < 0.001), the stability of blood pressure, cerebral perfusion pressure, pulse rates and oxygen saturation (all P < 0.001)seen individually, post operative ICP monitoring in the immediate (P = 0.002), within 24 hours (P < 0.001) and within 24-48 hours (P < 0.001) period, along with post operative pupillary size (P < 0.001) and motor score (P < 0.001). Post operatively, radiologically significant statistics included evidence of midline shift post operatively in the CT scan

    Study Design  Review of the literature. Objective  Surgery and cement augmentation procedures are effective palliative treatment of symptomatic spinal metastases. Our objective is to systematically review the literature to describe the survival, prognostic factors, and clinical outcomes of surgery and cement augmentation procedures for breast cancer metastases to the spine. Methods  We performed a literature review using PubMed to identify articles that reported outcomes and/or prognostic factors of the breast cancer patient population with spinal metastases treated with any surgical technique since 1990. Results  The median postoperative survival for metastatic breast cancer was 21.7 months (8.2 to 36 months), the mean rate of any pain improvement was 92.9% (76 to 100%), the mean rate of neurologic improvement was 63.8% (53 to 100%), the mean rate of neurologic decline was 4.1% (0 to 8%), and the local tumor control rate was 92.6% (89 to 100%). Kyphoplasty studies reported a high rate of pain control in selected patients. Negative prognostic variables included hormonal (estrogen and progesterone) and human epidermal growth factor receptor 2 (HER2) receptor refractory tumor status, high degree of axillary lymph node involvement, and short disease-free interval (DFI). All other clinical or prognostic parameters were of low or insufficient strength. Conclusion  With respect to clinical outcomes, surgery consistently yielded neurologic improvements in patients presenting with a deficit with a minimal risk of worsening; however, negative prognostic factors associated with shorter survival following surgery include estrogen receptor/progesterone receptor negativity, HER2 negativity, and a short DFI.

    Although a number of studies have indicated that the positive expression of nucleophosmin (NPM) and trefoil factor 3 (TFF3) is associated with oncogenesis and poor prognosis in several tumor types, the prognostic value of the co-expression of NPM and TFF3 in gastric cancer (GC) has not been fully elucidated. Therefore, in this study, we aimed to investigate the role of NPM and TFF3 in GC and determine their prognostic value. We retrospectively reviewed 108 patients who had undergone radical gastric tumor resection. The expression of NPM and TFF3 was detected by immunohistochemistry and the association of NPM and TFF3 with clinicopathological characteristics was investigated using the Chi-square test. Furthermore, univariate and multivariate analyses were conducted to determine the prognostic value of these markers. Of the 108 samples, NPM was positive in 57 (53%) and TFF3 was positive in 54 samples (50%). The positive expression of NPM was correlated with advanced tumor stage and recurrence (P=0.0333 and P<0.0001, respectively), whereas the expression of TFF3 was associated with larger tumor size (P=0.0005), poor differentiation (P=0.0435), lymph node metastasis (P=0.0116), advanced tumor stage (P=0.0244) and recurrence (P=0.0116). The univariate analysis revealed that the expression of NPM, the expression of TFF3 and the co-expression of the two were associated with poor survival (P=0.0004, 0.0028 and 0.0020, respectively). By multivariate analysis, all three factors were identified as independent prognostic factors in postoperative GC patients (hazard ratio = 1.970, 2.021 and 2.339, respectively). In conclusion, the expression of NPM and TFF3 and, particularly, the co-expression of the two, may serve as independent prognostic factors in postoperative GC patients.

    Purpose: To investigate the factors that influence clinical outcomes after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC). Methods and Materials: A total of 101 consecutive patients who underwent SBRT with 48 Gy in 4 fractions for histologically confirmed Stage I NSCLC were enrolled in this study. Factors including age, maximal tumor diameter, sex, performance status, operability, histology, and overall treatment time were evaluated with regard to local progression (LP), disease progression (DP), and overall survival (OS) using the Cox proportional hazards model. Prognostic models were built with recursive partitioning analysis. Results: Three-year OS was 58.6% with a median follow-up of 31.4 months. Cumulative incidence rates of LP and DP were 13.2% and 40.8% at 3 years, respectively. Multivariate analysis demonstrated that tumor diameter was a significant factor in all endpoints of LP, DP, and OS. Other significant factors were age in DP and sex in OS. Recursive partitioning analysis indicated a condition for good prognosis (Class I) as follows: female or T1a (tumor diameter {<=}20 mm). When the remaining male patients with T1b-2a (>20 mm) were defined as Class II, 3-year LP, DP, and OS were 6.8%, 23.6%, and 69.9% in recursive partitioning analysis Class I, respectively, whereas these values were 19.9%, 58.3%, and 47.1% in Class II. The differences between the classes were statistically significant. Conclusions: Tumor diameter and sex were the most significant factors in SBRT for NSCLC. T1a or female patients had good prognosis.

    Atypical and malignant meningiomas are rare. Our aim was to examine the treatment outcomes following surgical resection, and analyze associations between clinical characteristics and overall survival (OS) or relapse free survival (RFS). 102 patients with atypical or malignant meningiomas underwent microsurgical resection between June 2001 and November 2009 were analyzed retrospectively. We compared demographics, clinical characteristics, treatment, and complications. The five-year and ten-year overall survival rates were 93.5% and 83.4%, respectively. Three factors significantly reduced OS: Malignant meningiomas (p < 0.001), which also decreased RFS (p < 0.001); female patients (p = 0.049), and patients with Karnofsky Performance Status (KPS) < 70 at diagnosis (p = 0.009). Fifty two patients (51%) experienced tumor relapse. Total resection of tumors significantly impacted RFS (p = 0.013). Tumors located at parasagittal and posterior fossa area lead to higher relapse rate (p = 0.004). Subtotal resection without adjuvant radiotherapy lead to the worst local control of tumor (p = 0.030). An MIB-1 index <8% improved OS and RFS (p = 0.003). Total resection of atypical and malignant meningiomas provided better outcome and local control. Adjuvant radiation therapy is indicated for patients with malignant meningiomas, with incompletely excised tumors; or with tumors in the parasagittal or posterior fossa area. The MIB-1 index of the tumor is an independent prognostic factor of clinical outcome. PMID:27760993

    Early detection and effective treatments have dramatically improved breast cancer survivorship, yet the risk of relapse persists even 15 years after the initial diagnosis. It is important to identify prognostic factors for late breast cancer events. The authors investigated time-varying effects of tumor characteristics on breast-cancer-free survival using data on 3,088 breast cancer survivors from 4 US states who participated in a randomized dietary intervention trial in 1995-2006, with maximum follow-up through 15 years (median, 9 years). A piecewise constant penalized spline approach incorporating time-varying coefficients was adopted, allowing for deviations from the proportional hazards assumption. This method is more flexible than standard approaches, provides direct estimates of hazard ratios across time intervals, and is computationally tractable. Having a stage II or III tumor was associated with a 3-fold higher hazard of breast cancer than having a stage I tumor during the first 2.5 years after diagnosis; this hazard ratio decreased to 2.1 after 7.7 years, but higher tumor stage remained a significant risk factor. Similar diminishing effects were found for poorly differentiated tumors. Interestingly, having a positive estrogen receptor status was protective up to 4 years after diagnosis but detrimental after 7.7 years (hazard ratio = 1.5). These results emphasize the importance of careful statistical modeling allowing for possibly time-dependent effects in long-term survivorship studies. PMID:19403844

    Background: The cross-talk of hepatocellular carcinoma (HCC) cells and abnormal metabolic signals in peritumoral microenvironment modifies our knowledge of hepatocarcinogenesis. As an indispensable modulator of various stresses, the clinical significance of heat-shock transcription factor-1 (HSF1) in HCC microenvironment has never been defined. Methods: Hepatocellular carcinoma and matched peritumoral liver tissues (n=332) were semiquantitatively analysed for HSF1 expression, followed by correlation with clinicopathological parameters (patient outcomes). Moreover, the effects of HSF1 deficiency in L02 on monocarboxylate transporter-4 (MCT4) and HCC cells' colonisation and proliferation were investigated. Results: High expression of HSF1 in peritumoral tissue but not in HCC tissue was associated with poorer overall survival (OS) and time to recurrence (TTR), especially early recurrence (ER), which was further reconfirmed in validation cohort. Multivariate analysis showed that prognostic performance of peritumoral HSF1 was independent of other clinicopathological factors (hazard ratio for OS=2.60, P=0.002, for TTR=2.52, P<0.001). Notably, downregulation of HSF1 in L02 decreased MCT4 expression significantly. The supernatant from L02-shRNA-HSF1 in hypoxia, NOT normoxia condition, inhibited HCC cell colonisation and proliferation. Moreover, the combination of peritumoral HSF1 and MCT4 was the best predictor for ER and OS. Conclusion: High peritumoral HSF1 expression can serve as a sensitive ‘readout' for high-risk HCC ER, and could be a potential metabolic intervention target following curative resection.

    The role of circulating tumour cells (CTCs) in advanced oesophageal cancer (EC) patients undergoing concurrent chemoradiotherapy (CCRT) remains uncertain. A negative selection protocol plus flow cytometry was validated to efficiently identify CTCs. The CTC number was calculated and analysed for survival impact. The protocol's efficacy in CTC identification was validated with a recovery rate of 44.6 ± 9.1% and a coefficient of variation of 20.4%. Fifty-seven patients and 20 healthy donors were enrolled. Initial staging, first response to CRT, and surgery after CRT were prognostic for overall survival, with P values of <0.0001, <0.0001, and <0.0001, respectively. The CTC number of EC patients is significantly higher (P = 0.04) than that of healthy donors. Multivariate analysis for disease-specific progression-free survival showed that surgery after response to CCRT, initial stage, and CTC number (≥21.0 cells/mL) played independent prognostic roles. For overall survival, surgery after CCRT, performance status, initial stage, and CTC number were significant independent prognostic factors. In conclusion, a negative selection plus flow cytometry protocol efficiently detected CTCs. The CTC number before CCRT was an independent prognostic factor in patients with unresectable oesophageal squamous cell carcinoma. Further large-scale prospective studies for validation are warranted. PMID:27530152

    Computer-aided image analysis (CAI) can help objectively quantify morphologic features of hematoxylin-eosin (HE) histopathology images and provide potentially useful prognostic information on breast cancer. We performed a CAI workflow on 1,150 HE images from 230 patients with invasive ductal carcinoma (IDC) of the breast. We used a pixel-wise support vector machine classifier for tumor nests (TNs)-stroma segmentation, and a marker-controlled watershed algorithm for nuclei segmentation. 730 morphologic parameters were extracted after segmentation, and 12 parameters identified by Kaplan-Meier analysis were significantly associated with 8-year disease free survival (P < 0.05 for all). Moreover, four image features including TNs feature (HR 1.327, 95%CI [1.001 - 1.759], P = 0.049), TNs cell nuclei feature (HR 0.729, 95%CI [0.537 - 0.989], P = 0.042), TNs cell density (HR 1.625, 95%CI [1.177 - 2.244], P = 0.003), and stromal cell structure feature (HR 1.596, 95%CI [1.142 - 2.229], P = 0.006) were identified by multivariate Cox proportional hazards model to be new independent prognostic factors. The results indicated that CAI can assist the pathologist in extracting prognostic information from HE histopathology images for IDC. The TNs feature, TNs cell nuclei feature, TNs cell density, and stromal cell structure feature could be new prognostic factors. PMID:26022540

    Background Positive esophageal proximal resection margin (ERM+) following esophagectomy was considered as incomplete or R1 resection. The clinicopathological data and long-term prognosis of esophageal cancer (EC) patients with ERM+ after esophagectomy were still unknown. Therefore, the aim of this study was to assess the clinical significance of ERM+ and its therapeutic option. Methods From November 2008 to December 2014, 3,594 patients with histologically confirmed EC underwent radical resection in our department. Among them there were 37 patients (1.03%) who had ERM+. ERM+ was defined as carcinoma or atypical hyperplasia (severe or moderate) at the residual esophageal margin in our study. For comparison, another 74 patients with negative esophageal proximal resection margin (ERM−) were propensity-matched at a ratio of 1:2 as control group according to sex, age, tumor location and TNM staging. The relevant prognostic factors were investigated by univariate and multivariate regression analysis. Results In this large cohort of patients, the rate of ERM+ was 1.03%. The median survival time was 35.000 months in patients with ERM+, significantly worse than 68.000 months in those with ERM− (Chi-square =4.064, P=0.044). Survival in patients with esophageal residual atypical hyperplasia (severe or moderate) was similar to those with esophageal residual carcinoma. Survival rate in stage I–II was higher than that in stage III–IV (Chi-square =27.598, P=0.000) in ERM−; But there was no difference between the two subgroups of patients in ERM+. Furthermore, in those patients with ERM+, survival was better in those who having adjuvant therapy, compared to those without adjuvant therapy (Chi-square =5.480, P=0.019). And the average survival time which was improved to a well situation for ERM+ patients who have adjuvant therapy was 68.556 months which is comparable to average survival time (65.815 months) of ERM− for those patients who are at earlier stages

    The detection of circulating tumor cells (CTCs) in peripheral blood is currently an important field of study. Detection of CTCs by the OBP-401 assay (TelomeScan(®)) has previously been reported to be useful in the diagnosis, prognosis and evaluation of therapeutic efficacy in breast and gastric cancer. The aim of the present study was to evaluate the OBP-401 assay as a novel method of detecting CTCs of small cell lung cancer (SCLC) patients and to evaluate whether CTC count is associated with prognosis. Prospectively, 30 consecutively diagnosed SCLC patients who had commenced chemotherapy or chemoradiotherapy were enrolled as subjects of the current study. Peripheral blood specimens were collected from the SCLC patients prior to and following the initiation of treatment and the viable CTCs were detected in the specimens following incubation with a telomerase-specific, replication-selective, oncolytic adenoviral agent, which was carrying the green fluorescent protein gene. CTCs were detected in 29 patients (96%). The group of 21 patients with a CTC count of <2 cells/7.5 ml prior to treatment (baseline) had a significantly longer median survival time than the group of eight patients with a CTC count of ≥2 cells/7.5 ml prior to treatment (14.8 and 3.9 months, respectively; P=0.007). The results of a multivariate analysis showed that the baseline CTC count was an independent prognostic factor for survival time (hazard ratio, 3.91; P=0.026). Among the patients that achieved a partial response to treatment, patients who had a CTC count of <2 cells/7.5 ml following two cycles of chemotherapy tended to have a longer median progression-free survival compared with patients who had a CTC count of ≥2 cell/7.5 ml (8.3 and 3.8 months, respectively; P=0.07). Therefore, CTCs may be detected via OBP-401 assay in SCLC patients and the CTC count prior to treatment appears to be a strong prognostic factor. PMID:24765158

    Purpose: To investigate potential prognostic factors, including hemoglobin levels before and during radiotherapy, for associations with survival and local control in patients with unirradiated locally recurrent rectal cancer. Patients and Methods: Ten potential prognostic factors were investigated in 94 patients receiving radiotherapy for recurrent rectal cancer: age ({<=}68 vs. {>=}69 years), gender, Eastern Cooperative Oncology Group performance status (0-1 vs. 2-3), American Joint Committee on Cancer (AJCC) stage ({<=}II vs. III vs. IV), grading (G1-2 vs. G3), surgery, administration of chemotherapy, radiation dose (equivalent dose in 2-Gy fractions: {<=}50 vs. >50 Gy), and hemoglobin levels before (<12 vs. {>=}12 g/dL) and during (majority of levels: <12 vs. {>=}12 g/dL) radiotherapy. Multivariate analyses were performed, including hemoglobin levels, either before or during radiotherapy (not both) because these are confounding variables. Results: Improved survival was associated with better performance status (p < 0.001), lower AJCC stage (p = 0.023), surgery (p = 0.011), chemotherapy (p = 0.003), and hemoglobin levels {>=}12 g/dL both before (p = 0.031) and during (p < 0.001) radiotherapy. On multivariate analyses, performance status, AJCC stage, and hemoglobin levels during radiotherapy maintained significance. Improved local control was associated with better performance status (p = 0.040), lower AJCC stage (p = 0.010), lower grading (p = 0.012), surgery (p < 0.001), chemotherapy (p < 0.001), and hemoglobin levels {>=}12 g/dL before (p < 0.001) and during (p < 0.001) radiotherapy. On multivariate analyses, chemotherapy, grading, and hemoglobin levels before and during radiotherapy remained significant. Subgroup analyses of the patients having surgery demonstrated the extent of resection to be significantly associated with local control (p = 0.011) but not with survival (p = 0.45). Conclusion: Predictors for outcome in patients who received radiotherapy for

    Background Peptic ulcer perforation (PUP) is a very serious condition that leads to excessive complications and mortality. This study aimed to explore the possible prognostic factors and complications in patients with perforated peptic ulcer operation. Methods A 6-year retrospective cohort study in Nakornping Hospital between January 1, 2005 and December 31, 2010 was conducted. The study included 912 patients who underwent PUP surgery. Patient characteristics were analyzed by using frequency, percentage, mean (standard deviation) and median (range). A comparison between groups was made. The Pearson’s Chi-squared or Fisher’s exact test was used for categorical variables, as appropriate. The Student’s t test was used for continuous variables with normal distribution, and Wilcoxon rank sum test was performed for continuous variables with non-normal distributions. Exponential risk regression analysis was performed to estimate the relative risk (RR) for the prognostic factors with a probability value of < 0.05 as a statistically significant value. Post-operative length of stay was computed graphically based on Kaplan-Meier estimates. Results During the study period, 912 post-operative PUP patients were observed. The median age of patients was 78.5 (15 - 92) years, and 77.74% of the patients were male gender. Multivariate analysis showed that five prognostic indicators: underlying illnesses; liver disease (RR: 5.41; 95% confidence interval (CI): 1.36 - 21.56) and kidney disease (RR: 4.72; 95% CI: 1.05 - 21.11); duration of operation > 3 h (RR: 9.83; 95% CI: 1.61-59.66); unplanned admission to ICU (RR: 9.22; 95% CI: 1.55 - 54.68); and prolonged ventilation > 24 h (RR: 9.02; 95% CI: 0.42 - 9.98) were associated with post-operative PUP complications. Post-operative complications developed in 87 (9.54%) patients with 135 complications: 11 (1.21%) patients underwent re-operation, 32 (3.51%) patients suffered with surgical site infection, 74 (8.11%) patients encountered

    We revisited the prognostic value of frequently detected somatic gene copy number alterations (CNAs) in mantle cell lymphoma (MCL) patients treated first line with immunochemotherapy and autologous stem cell transplantation (ASCT), with or without high-dose cytarabine, in the randomized European MCL Younger trial. DNA extracted from tumor material of 135 patients (median age, 56 years) was analyzed by multiplex ligation-dependent probe amplification and/or quantitative multiplex polymerase chain reaction of short fluorescent fragments. As expected, MYC (18%) was the more frequently gained, whereas RB1 (26%), ATM (25%), CDKN2A (p16) (25%), and TP53 (22%) were the more frequently deleted. Whether adjusted for MCL International Prognostic Index (MIPI) or not, deletions of RB1, CDKN2A, TP53, and CDKN1B were associated with shorter overall survival (OS), similarly in both treatment arms, whereas CNAs in MYC, ATM, CDK2, CDK4, and MDM2 had no prognostic value. Additive effects were seen for CDKN2A (hazard ratio, 2.3; P = .007, MIPI-adjusted) and TP53 deletions (hazard ratio, 2.4; P = .007), reflected in a dismal outcome with simultaneous deletions (median OS, 1.8 years) compared with single deletions (median OS, 4.3 and 5.1 years) or without these deletions (median OS, 7 years), again similarly in both treatment arms. The additive prognostic effects of CDKN2A and TP53 deletions were independent of the Ki-67 index. Despite immunochemotherapy, high-dose cytarabine, and ASCT, younger MCL patients with deletions of CDKN2A (p16) and TP53 show an unfavorable prognosis and are candidates for alternative therapeutic strategies. This trial was registered at www.clinicaltrials.gov as #NCT00209222. PMID:26022239

    Purpose To evaluate long-term outcomes and identify prognostic factors of trabeculectomy following intraocular bevacizumab injection for neovascular glaucoma. Methods Sixty-one eyes of 54 patients with neovascular glaucoma treated by trabeculectomy following intraocular bevacizumab injection were consecutively enrolled. Surgical success criteria were sufficient intraocular pressure (IOP) reduction (IOP ≤21 mmHg, ≥20% IOP reduction, no additional medications or glaucoma surgeries) without devastating complications (loss of light perception, phthisis bulbi, and endophthalmitis) or significant hypotony (IOP ≤5 mmHg continued ≥6 months and until the last follow-up visit or hypotony requiring intervention). Kaplan-Meier survival curves and Cox regression analysis were used to examine success rates and risk factors for surgical outcomes. Results The follow-up period after trabeculectomy was 45.0 ± 22.2 months (mean ± standard deviation). Surgical success rate was 86.9 ± 4.3% (± standard error), 74.0 ± 6.1%, and 51.3 ± 8.6% at 1, 3, and 5 years. Multivariate Cox regression analysis identified two risk factors; lower preoperative IOP (≤30 mmHg) for surgical failure and hypotony [hazard ratio (HR), 2.92, 6.64; 95% confidence interval (CI), 1.22 to 7.03, 1.47 to 30.0; P = 0.018, 0.014, respectively], and vitrectomy after trabeculectomy for surgical failure with or without hypotony criteria (HR, 2.32, 4.06; 95% CI, 1.02 to 5.28, 1.30 to 12.7; P = 0.045, 0.016, respectively). Conclusions The long-term outcomes of trabeculectomy following intraocular bevacizumab injection for neovascular glaucoma were favorable. Lower baseline IOP was associated with development of significant hypotony, while additional vitrectomy was related to insufficient IOP reduction. PMID:26275060

    Abstract To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) in clinical practice. We performed a multicenter prospective study in Japan of biological disease-modifying antirheumatic drug (bDMARD)-naive RA patients with moderate to high disease activity treated with conventional synthetic DMARDs (csDMARDs) at study entry. We longitudinally observed 408 patients for 1 year and assessed disease activity every 3 months. CRRP was defined as yearly progression of modified total Sharp score (mTSS) > 3.0 U. We also divided the cohort into 2 groups based on disease duration (<3 vs ≥3 years) and performed a subgroup analysis. CRRP was found in 10.3% of the patients. A multiple logistic regression analysis revealed that the independent variables to predict the development of CRRP were: CRP at baseline (0.30 mg/dL increase, 95% confidence interval [CI] 1.01–1.11), time-integrated Disease Activity Score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) during the 1 year postbaseline (12.4-unit increase, 95%CI 1.17–2.59), RA typical erosion at baseline (95%CI 1.56–21.1), and the introduction of bDMARDs (95%CI 0.06–0.38). The subgroup analysis revealed that time-integrated DAS28-ESR is not a predictor whereas the introduction of bDMARDs is a significant protective factor for CRRP in RA patients with disease duration <3 years. We identified factors that could be used to predict the development of CRRP in RA patients treated with DMARDs. These variables appear to be different based on the RA patients’ disease durations.

    Background: Many laboratories are currently evaluating the usefulness of the determination of human epidermal growth factor receptor 2 (HER2), p53, and Ki67 proliferation indices using immunohistochemical techniques in cancer. Although the available studies suggest that these factors might indeed be helpful in making treatment decisions in osteosarcoma patients, their clinical usefulness is still controversial. Aims: We proposed to introduce the value of the coexistence of HER2 overexpression, p53 protein accumulation, and Ki67 in osteosarcoma, which could be a prognostic factor in osteosarcoma. Material and Methods: Expression of HER2, p53, and Ki67 was examined by immunohistochemistry in samples of resected bone tumor tissue from 56 patients with osteosarcoma, obtained between 2009 and 2014 (median follow-up period of 48 months), and their significance for prognosis was analyzed. Results: Of the 56 osteogenic sarcoma tissue samples, 80, 89, and 96.5% were positive for HER2 overexpression, p53 protein accumulation, and Ki67 expression, respectively. Overexpression of HER2 and accumulation of p53 protein significantly correlated with reduced disease-free (P < 0.01) and overall survival (P < 0.003). HER2 and Ki67 co-overexpression significantly correlated with decreased disease-free (P < 0.03) and overall survival (P < 0.02). HER2, accumulation of p53 protein, and Ki67 co-overexpression significantly correlated with reduced disease-free (P < 0.01) and overall survival (P < 0.005) as did patients with larger tumor size, high grade of tumor, positive lymph node, and metastasis status within the specified period of follow up. Conclusions: We found evidence that coexistence of HER2 and Ki67 overexpression and p53 protein accumulation predict the development of lymph node involvement and metastases in patients with high-grade osteosarcoma and were significantly associated with reduced survival.

    Patients with chronic lymphocytic leukaemia (CLL) whose tumour cells harbour a 17p deletion (17p-) are universally considered to have a poor prognosis. The deletion can be detected at diagnosis or during the evolution of the disease, particularly in patients who have received chemotherapy. We sought to evaluate the natural history of patients with 17p- CLL, identify predictive factors within this prognostic subgroup, and evaluate the results of different therapeutic approaches. Data from 294 patients with 17p- CLL followed up at 20 different institutions was retrospectively collected and analysed. Median age was 68 (range 27-98) years at the time of fluorescence in situ hybridization analysis. After 17p- documentation, 52% received treatment, achieving an overall response rate of 50%. Median overall survival was 41 months, and was significantly shorter in patients with elevated beta(2)-microglobulin concentration (P < 0·001), B symptoms (P = 0·016), higher percentage of cells with deletion (P < 0·001), and acquired deletions (P = 0·012). These findings suggest that patients with 17p- CLL have a variable prognosis that can be refined using simple clinical and laboratory features, including 17p- clone size, beta2-microglobulin concentration, presence of B symptoms and type of deletion (de novo versus acquired).

    We describe the case of a patient with severe lactic acidosis, as well as presenting some data on its incidence, diagnosis, prognostic factors, and the most appropriate treatment. A 76 year-old male patient with diabetes on treatment with metformin, hypertension, dyslipaemia, and with mild cognitive impairment, was admitted to the Intensive Care Unit in a state of circulatory shock, requiring aggressive treatment with vasopressors and volume. The patient had acute kidney injury with an anuria of 3 days, probably secondary to dehydration to vomiting and to NSAIDs. As a result of the acute renal damage, the patient suffered a severe metformin-associated lactic acidosis. The rest of the causes of metabolic acidosis with an increased anion gap were ruled out, as well as a possible sepsis or rhabdomyolysis. Metformin-associated lactic acidosis is an uncommon metabolic condition, but with a high mortality. To reduce the mortality of these patients, it is important to make an early diagnosis using the clinical records, physical examination, and laboratory tests, with an early resuscitation with volume, vasopressors, bicarbonate, and renal replacement therapy.

    Objective: To determine whether the expression of platelet derived growth factor α receptor (PDGFRα) in low grade astrocytomas and oligoastrocytomas is associated with survival. Methods: Formalin fixed and paraffin embedded tumour samples of 40 consecutive patients with supratentorial diffuse astrocytomas and oligoastrocytomas of WHO grade 2, resected between 1986 and 1993, were used for immunohistochemical staining. The fraction of tumour cells expressing PDGFRα protein was quantified and entered into univariate and multivariate survival analyses. Changes in PDGFα expression over time were analysed in seven patients in whom reoperations had been performed. Results: Patients with a relatively high fraction of PDGFRα expressing cells had a more favourable outcome in both univariate (p = 0.04) and multivariate analyses (p = 0.02). Expression of PDGFRα was greater in oligoastrocytomas than in astrocytomas (p = 0.05). In four reoperated patients with histologically confirmed malignant transformation, there was a marked decrease in the number of cells expressing the receptor. Conclusions: There is an association between high PDGFRα expression and long survival time in patients with grade 2 astrocytomas and oligoastrocytomas. The findings suggest that expression of the receptor may be a useful prognostic marker in such patients. PMID:12023424

    The data regarding the prognostic significance of EGFR (epidermal growth factor receptor) expression and adjuvant therapy in patients with resected pancreatic cancer are insufficient. We retrospectively investigated EGFR status in 357 resected PDAC (pancreatic duct adenocarcinoma) patients using tissue immunohistochemistry and validated the possible role of EGFR expression in predicting prognosis. The analysis was based on excluding the multiple confounding parameters. A negative association was found between overall EGFR status and postoperative survival (p = 0.986). Remarkably, adjuvant chemotherapy and radiotherapy were significantly associated with favorable postoperative survival, which prolonged median overall survival (OS) for 5.8 and 10.2 months (p = 0.009 and p = 0.006, respectively). Kaplan–Meier analysis showed that adjuvant chemotherapy correlated with an obvious survival benefit in the EGFR-positive subgroup rather than in the EGFR-negative subgroup. In the subgroup analyses, chemotherapy was highly associated with increased postoperative survival in the EGFR-positive subgroup (p = 0.002), and radiotherapy had a significant survival benefit in the EGFR-negative subgroup (p = 0.029). This study demonstrated that EGFR expression is not correlated with outcome in resected pancreatic cancer patients. Adjuvant chemotherapy and radiotherapy were significantly associated with improved survival in contrary EGFR expressing subgroup. Further studies of EGFR as a potential target for pancreatic cancer treatment are warranted. PMID:27399694

    Up to 20% of patients with pilocytic astrocytoma (PA) experience a poor outcome. BRAF alterations and Fibroblast growth factor receptor 1 (FGFR1) point mutations are key molecular alterations in Pas, but their clinical implications are not established. We aimed to determine the frequency and prognostic role of these alterations in a cohort of 69 patients with PAs. We assessed KIAA1549:BRAF fusion by fluorescence in situ hybridization and BRAF (exon 15) mutations by capillary sequencing. In addition, FGFR1 expression was analyzed using immunohistochemistry, and this was compared with gene amplification and hotspot mutations (exons 12 and 14) assessed by fluorescence in situ hybridization and capillary sequencing. KIAA1549:BRAF fusion was identified in almost 60% of cases. Two tumors harbored mutated BRAF. Despite high FGFR1 expression overall, no cases had FGFR1 amplifications. Three cases harbored a FGFR1 p.K656E point mutation. No correlation was observed between BRAF and FGFR1 alterations. The cases were predominantly pediatric (87%), and no statistical differences were observed in molecular alterations-related patient ages. In summary, we confirmed the high frequency of KIAA1549:BRAF fusion in PAs and its association with a better outcome. Oncogenic mutations of FGFR1, although rare, occurred in a subset of patients with worse outcome. These molecular alterations may constitute alternative targets for novel clinical approaches, when radical surgical resection is unachievable. PMID:26083571

    In order to fully elucidate the association between serum fibrinogen and prognosis of esophageal cancer, we examined serum fibrinogen concentrations in 1512 patients who underwent esophagectomy by the Clauss method. The impact of fibrinogen on overall survival and disease-free survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. Hyperfibrinogenemia was significantly associated with older age, male gender, smoking, alcohol consumption, weight loss, advanced pathological T stage and lymph node metastasis. Patients with hyperfibrinogenemia exhibited poor OS (HR=1.20, 95%CI: 1.04-1.38, P=0.012) and DFS (HR=1.18, 95%CI: 1.03-1.35, P=0.019). Subgroup analysis further exhibited an significant association between hyperfibrinogenemia and poor OS (P<0.001), DFS (P<0.001) in esophageal squamous cell carcinoma (P<0.001) and early pathological stage (I-II) (P=0.001). Collectively, this study indicates that preoperative serum fibrinogen is an independent prognostic factor for survival in esophageal cancer. PMID:27009857

    Nosocomial infections are an important cause of preventable morbidity and mortality; they also result in significant socioeconomic cost. Nosocomial pneumonia (NCP) is defined as pneumonia, which occurs 48 hours after hospitalization or after discharge from the hospital. It is the second or third most frequent infection among all hospital acquired infections, and the mortality of NCP is higher than the other hospital acquired infections. Patients, diagnosed as NCP were retrospectively analyzed in order to detect microbiological agent and prognostic factors. We evaluated 173 patients, 67.0% of them were male and 33.0% female. Comorbid diseases were present in 94.2% and a medical procedure had been applied in 75.1% of cases. A single agent was isolated in 79.2% of the cases while a mixt infection was present in 13.3%. In 7.5% of the cases, cultures were negative. Endotracheal aspirates were the most common materials (38.9%) used for detected microorganism and sputum cultures were used in 16.8% of the cases. Most commonly encountered microorganism were Pseudomonas aeruginosa, Acinetobacter spp. and Staphylococcus aureus respectively. NCP developed on approximately 18th day of hospitalization. Overall mortality rate was 45.2%. The effects of diabetes mellitus and chronic pulmonary diseases on mortality rate were analized by logistic regression analysis and it's evaluated that the mortality rates increase 3.7 times with diabetes mellitus and 2.4 times with chronic pulmonary diseases. There was no effect of mechanical ventilation history on mortality.

    The diffusion of laryngeal cancer cells in the perineural space is a parameter associated with a negative prognosis, high loco-regional recurrence and low disease-free survival rates. The spread of tumor cells on the perineural sheath highlights the histopathological and clinically aggressive behavior of this type of tumor, which may extend proximally or distally in the nerve for >10 cm. Therefore, the surgical resection margin is generally insufficient to treat patients with laryngeal cancer presenting with perineural invasion (PNI) with surgery alone. In PNI, the minor laryngeal nerves are frequently involved, rather than the superior and inferior laryngeal nerves. The aim of the present study was: i) To evaluate the prognostic importance of PNI; ii) to correlate the rate of infiltration with factors associated with the tumor, including histotype, site and tumor-node-metastasis stage, and with the type of surgery (total or partial laryngectomy); and iii) to evaluate the rate of disease-free survival according to the outcome of combined surgery and radiotherapy (RT) treatment, by means of retrospective analysis. The results of the present study highlighted the importance of performing a closer clinical and instrumental follow-up in patients with laryngeal cancer whose histopathological examination is positive for PNI. In such cases, it is important to complement the surgical therapeutic treatment with adjuvant RT. PMID:27073523

    Acute myelogenous leukemia (AML) is a heterogeneous disorder characterized by clonal proliferation of stem cell-like blasts in bone marrow (BM); however, their unique cellular interaction within the BM microenvironment and its functional significance remain unclear. Here, we assessed the BM microenvironment of AML patients and demonstrate that the leukemia stem cells induce a change in the transcriptional programming of the normal mesenchymal stromal cells (MSC). The modified leukemic niche alters the expressions of cross-talk molecules (i.e., CXCL12 and JAG1) in MSCs to provide a distinct cross-talk between normal and leukemia cells, selectively suppressing normal primitive hematopoietic cells while supporting leukemogenesis and chemoresistance. Of note, AML patients exhibited distinct heterogeneity in the alteration of mesenchymal stroma in BM. The distinct pattern of stromal changes in leukemic BM at initial diagnosis was associated with a heterogeneous posttreatment clinical course with respect to the maintenance of complete remission for 5 to 8 years and early or late relapse. Thus, remodeling of mesenchymal niche by leukemia cells is an intrinsic self-reinforcing process of leukemogenesis that can be a parameter for the heterogeneity in the clinical course of leukemia and hence serve as a potential prognostic factor.

    Oral squamous cell carcinoma (OSCC) is the most common oral cancer. Hypoxia inducible factor (HIF) is involved in many malignant tumors' growth and metastasis and upregulated by hypoxia, including oral cancer. Many studies have studied about the prognostic value of HIF expression in OSCC; however, they do not get the consistent results. Therefore, this study explored the correlation between the HIF expression and the prognosis of OSCC. It conducted a meta-analysis of relevant publications searched in the Web of Science, PubMed, and ISI Web of Knowledge databases. Totally, this study identified 12 relevant articles reporting a total of 1112 patients. This analysis revealed a significant association between increased risk of mortality (RR = 1.20; 95 % CI 0.74-1.95; I (2) 85.4 %) and overexpression of HIFs. Furthermore, different HIF isoforms were associated with overall survival [HIF-1α (RR = 1.18; 95 % CI 0.66-2.11; I (2) 87.2 %) and HIF-2α (RR = 1.40; 95 % CI 0.93-2.09; I(2) 0.0 %)]. These results show that overexpression of HIFs, regardless of whether the HIF-1α or HIF-2α isoforms are overexpressed is significantly associated with increased risk of mortality in OSCC patients. In this study, the funnel is symmetric, suggesting existed no publication bias.

    This study concerns the effects of several pre-transplant features on outcome for patients with beta thalassemia major who underwent bone marrow transplantation (BMT). Seventy patients with beta thalassemia major underwent bone marrow transplantation during the period 1991-1997 in Shariati Hospital in Tehran, Iran. The survival and rejection curves levelled off at 8 and 18 months after transplantation at 82.6% and 11.4%, respectively. Pre-transplant clinical features (age, serum ferritin, portal fibrosis, hepatomegaly and quality of chelation therapy) were examined for their effects on survival and recurrence of thalassemia in this group of patients who were less than 16 years old. Increasing age, presence of portal fibrosis and increasing serum ferritin were significantly associated with reduced probability of survival (P = 0.0047, P = 0.016 and P = 0.024, respectively). Hepatomegaly and inadequate pre-transplant chelation therapy which were documented as poor prognostic factors in previous studies, were not evaluable in this study. We also showed the benefits of transplanting more than 5.5 x 10(8)/kg cells in this group of patients with no increase in complications.

    Acute-on-chronic liver failure (ACLF) is increasingly recognized as a complex syndrome that is reversible in many cases. It is characterized by an acute deterioration of liver function in the background of a pre-existing chronic liver disease often associated with a high short-term mortality rate. Organ failure (OF) is always associated, and plays a key role in determining the course, and the outcome of the disease. The definition of ACLF remains controversial due to its overall ambiguity, with several disparate criteria among various associations dedicated to the study of liver diseases. Although the precise pathogenesis needs to be clarified, it appears that an altered host response to injury might be a contributing factor caused by immune dysfunction, ultimately leading to a pro-inflammatory status, and eventually to OF. The PIRO concept (Predisposition, Insult, Response and Organ Failure) has been proposed to better approach the underlying mechanisms. It is accepted that ACLF is a different and specific form of liver failure, where a precipitating event is always involved, even though it cannot always be ascertained. According to several studies, infections and active alcoholism often trigger ACLF. Viral hepatitis, gastrointestinal haemorrhage, or drug induced liver injury, which can also provoke the syndrome. This review mainly focuses on the physiopathology and prognostic aspects. We believe these features are essential to further understanding and providing the rationale for improveddisease management strategies. PMID:26576097

    Background Cholangiocarcinoma is one of the most common malignancies in China. Surgical resection is the only treatment option; however, diagnosis at advanced stage precludes surgery. Comprehensive knowledge of prognostic markers is missing. Hence, the aim of this study was to determine clinicopathological indexes that would be indicative of prognosis in post-operative cases of cholangiocarcinoma. Material/Methods A retrospective analysis of 293 cases of cholangiocarcinoma patients attending the 301 Military Hospital in Beijing, China between January 2004 and December 2010 were included in the study. The patients had follow-up history until August 2012. Cox proportional hazards model analysis was performed to identify indexes of prognosis. All indicators were analyzed by univariate and multivariate analysis. Results The median follow-up time was 55.90 months, with recurrence and metastasis in 162 cases (55.3%) and death in 223 cases (76.1%). The 1-year, 3-year, and 5-year survival rates were 71.7%, 38.2%, and 10.6%, respectively. The independent risk factors of overall survival were degree of tumor differentiation, TNM stage, surgical margin, intraoperative blood transfusion, tumor location, alkaline phosphatase levels in blood, and relapse. Conclusions Good prognosis in cholangiocarcinoma patients is indicated by highly differentiated tumor, early stages of TNM staging, no resection margin invaded, no intraoperative blood transfusion, intrahepatic tumor, normal alkaline phosphatase levels, and no relapse.

    Objectives. Thyroid carcinomas incidence, in particular papillary variants, is increasing. These cancers are generally considered to have excellent prognosis, and papillary microcarcinomas are usually noninvasive. Many prognostic histopathology factors have been described to guide therapeutic decisions. Most patients are treated with total thyroidectomy without radioiodine treatment or partial surgery. Case Summary. A 65-year-old man with no significant medical history presented with pain in the left chest wall that had been present for several months. A computed tomography (CT) found a large tissue mass of 4 cm responsible for lysis of the middle arch of the 4th rib on the left. It was a single lesion, highly hypermetabolic on the 18-FDG PET/CT. The histology analysis of the biopsy and surgical specimen favored an adenocarcinoma with immunostaining positive for TTF1 and thyroglobulin (Tg). The total thyroidectomy carried out subsequently revealed a 4 mm papillary microcarcinoma with vesicular architecture of the right lobe, well delimited and distant from the capsule without vascular embolisms. After two radioiodine treatments, the patient is in complete clinical, biological, and radiological remission. Conclusion. This extremely rare case of a singular bone metastasis revealing a papillary thyroid microcarcinoma illustrates the necessity of further research to better characterize the forms of papillary thyroid microcarcinomas with potentially poor prognosis.

    The effect of varicocele repair on male fertility remains controversial. It would be helpful to determined which men would benefit most from varicocele repair, and target repair efforts at those individuals. A detailed review of the literature on prognostic factors for varicocele repair was performed using the PubMed NLM database. We found that the best predictor of postvaricocelectomy semen parameters is the preoperative semen parameters. The greatest improvements in semen parameters were found in men with larger varicoceles. While there is controversy, higher testosterone, younger age and larger testis size, in some studies predict for improvements in semen parameters postvaricocelectomy. A nomogram has been developed to predict the postvaricocelectomy semen parameters based on the preoperative semen parameters, varicocele grade and the age of the man (www.fertilitytreatmentresults.com). Limited data consistently demonstrates the greatest improvements in DNA fragmentation rates in men with higher baseline DNA fragmentation rates. With respect to reproductive outcomes, higher baseline sperm density consistently predicts for natural pregnancy or assisted reproductive technology (ART) pregnancy rates. In addition, varicocele repair does seem to reduce the need for more invasive modalities of ART. In conclusion, we can now start to use specific parameters such as baseline semen quality, varicocele grade and patient age to predict post-repair semen quality and fertility potential following varicocelectomy.

    The separate unplanned analysis of women ages 40-49 in population-based randomized controlled trials has resulted in demonstration of statistically significant breast cancer mortality reduction due to screening mammography in only two of the individual trials, and in all such trials only through meta-analysis. Therefore, many researchers have utilized the surrogate endpoints of tumor size and axillary lymph node status to evaluate screening efficacy. For the present study, these endpoints were evaluated in an audit of 854 screen-detected cancers found in 147,125 mammographic examinations performed in women over 40 between 1988 and 1994 in a community practice setting. The concerns that mammography in the 40-49 group has a lower sensitivity and higher biopsy rate were also addressed. Median invasive tumor size and lymph node positivity were found to be equally small (1.0-1.1 cm and 13.5-12.2%, respectively), and the sensitivity and overall biopsy rate were found to be constant over all ages 40 and above. Positive biopsy rate (PBR) varied directly with increasing age, paralleling the measured cancer detection rate in each decade, with no abrupt change at age 50. We conclude that modern mammography in a community practice setting can successfully detect breast cancers with favorable prognostic factors and achieve constant sensitivity and acceptable PBRs in all women over 40. Our data also suggest that many of the large differences seen by inappropriately dividing data at age 50 decrease or disappear when analysis is performed by decade.

    A comparison with respect to possible prognostic factors has been made between a contemporary group of 44 patients with osteosarcoma in Sweden, who received treatment since 1971, and a historical group of 35 such patients treated prior to 1972. Only patients with no evidence of metastases on admission were included in the material. The female/male ratio was lower, but not significantly so, for the contemporary group. The mean age was similar in the two groups. Pain was the most common symptom in both groups. The site patterns differed slightly, although not significantly so, in the two groups, there was a higher ratio of frequency of femoral and lower leg tumors for the historical group than for the contemporary group. The variability in tumor size was greater for the historical group, as was the tumor diameter. The historical group had a greater proportion of osteoblastic tumors and these tended to be more malignant. On the whole the prognosis would be expected to be less favorable for the historical group and there would seem to be a definite risk in using this group as a control group to the adjuvant interferon treated patients.

    Patients with chronic lymphocytic leukaemia (CLL) whose tumour cells harbour a 17p deletion (17p-) are universally considered to have a poor prognosis. The deletion can be detected at diagnosis or during the evolution of the disease, particularly in patients who have received chemotherapy. We sought to evaluate the natural history of patients with 17p- CLL, identify predictive factors within this prognostic subgroup, and evaluate the results of different therapeutic approaches. Data from 294 patients with 17p- CLL followed up at 20 different institutions was retrospectively collected and analysed. Median age was 68 (range 27-98) years at the time of fluorescence in situ hybridization analysis. After 17p- documentation, 52% received treatment, achieving an overall response rate of 50%. Median overall survival was 41 months, and was significantly shorter in patients with elevated beta(2)-microglobulin concentration (P < 0·001), B symptoms (P = 0·016), higher percentage of cells with deletion (P < 0·001), and acquired deletions (P = 0·012). These findings suggest that patients with 17p- CLL have a variable prognosis that can be refined using simple clinical and laboratory features, including 17p- clone size, beta2-microglobulin concentration, presence of B symptoms and type of deletion (de novo versus acquired).

    Background: Estimating the prognosis in malignant pleural mesothelioma (MPM) remains challenging. Thus, the prognostic relevance of Ki67 was studied in MPM. Methods: Ki67 index was determined in a test cohort of 187 cases from three centres. The percentage of Ki67-positive tumour cells was correlated with clinical variables and overall survival (OS). The prognostic power of Ki67 index was compared with other prognostic factors and re-evaluated in an independent cohort (n=98). Results: Patients with Ki67 higher than median (>15%) had significantly (P<0.001) shorter median OS (7.5 months) than those with low Ki67 (19.1 months). After multivariate survival analyses, Ki67 proved to be—beside histology and treatment—an independent prognostic marker in MPM (hazard ratio (HR): 2.1, P<0.001). Interestingly, Ki67 was prognostic exclusively in epithelioid (P<0.001) but not in non-epithelioid subtype. Furthermore, Ki67 index was significantly lower in post-chemotherapy samples when compared with chemo-naive cases. The prognostic power was comparable to other recently published prognostic factors (CRP, fibrinogen, neutrophil-to-leukocyte ratio (NLR) and nuclear grading score) and was recapitulated in the validation cohort (P=0.048). Conclusion: This multicentre study demonstrates that Ki67 is an independent and reproducible prognostic factor in epithelioid but not in non-epithelioid MPM and suggests that induction chemotherapy decreases the proliferative capacity of MPM.

    Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL.From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed.In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4.High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not in the MALT

    AIM: To investigate the prognostic significance of insulin-like growth factor-binding protein 3 (IGFBP-3) in patients with cirrhosis. METHODS: Prospective study that included two cohorts: outpatients with stable cirrhosis (n = 138) and patients hospitalized for acute decompensation (n = 189). Development of complications, mortality or liver transplantation was assessed by periodical phone calls and during outpatient visits. The cohort of stable cirrhosis also underwent clinical and laboratory evaluation yearly (2013 and 2014) in predefined study visits. In patients with stable cirrhosis, IGFBP-3 levels were measured at baseline (2012) and at second re-evaluation (2014). In hospitalized subjects, IGFBP-3 levels were measured in serum samples collected in the first and in the third day after admission and stored at -80 °C. IGFBP-3 levels were measured by immunochemiluminescence. RESULTS: IGFBP-3 levels were lower in hospitalized patients as compared to outpatients (0.94 mcg/mL vs 1.69 mcg/mL, P < 0.001) and increased after liver transplantation (3.81 mcg/mL vs 1.33 mcg/mL, P = 0.008). During the follow-up of the stable cohort, 17 patients died and 11 received liver transplantation. Bivariate analysis showed that death or transplant was associated with lower IGFBP-3 levels (1.44 mcg/mL vs 1.74 mcg/mL, P = 0.027). The Kaplan-Meier transplant-free survival probability was 88.6% in patients with IGFBP-3 ≥ 1.67 mcg/mL and 72.1% for those with IGFBP3 < 1.67 mcg/mL (P = 0.015). In the hospitalized cohort, 30-d mortality was 24.3% and was independently associated with creatinine, INR, SpO2/FiO2 ratio and IGFBP-3 levels in the logistic regression. The 90-d transplant-free survival probability was 80.4% in patients with IGFBP-3 ≥ 0.86 mcg/mL and 56.1% for those with IGFBP3 < 0.86 mcg/mL (P < 0.001). CONCLUSION: Lower IGFBP-3 levels were associated with worse outcomes in patients with cirrhosis, and might represent a promising prognostic tool that can be incorporated in

    Brain-derived neurotrophic factor (BDNF) is important for neuronal survival and regeneration. We investigated the diagnostic and prognostic values of serum BDNF in traumatic brain injury (TBI). We examined serum BDNF in two independent cohorts of TBI cases presenting to the emergency departments (EDs) of the Johns Hopkins Hospital (JHH; n = 76) and San Francisco General Hospital (SFGH, n = 80), and a control group of JHH ED patients without TBI (n = 150). Findings were subsequently validated in the prospective, multi-center Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) Pilot study (n = 159). We investigated the association between BDNF, glial fibrillary acidic protein (GFAP), and ubiquitin C-terminal hydrolase-L1 (UCH-L1) and recovery from TBI at 6 months in the TRACK-TBI Pilot cohort. Incomplete recovery was defined as having either post-concussive syndrome or a Glasgow Outcome Scale Extended score <8 at 6 months. Median day-of-injury BDNF concentrations (ng/mL) were lower among TBI cases (JHH TBI, 17.5 and SFGH TBI, 13.8) than in JHH controls (60.3; p = 0.0001). Among TRACK-TBI Pilot subjects, median BDNF concentrations (ng/mL) were higher in mild (8.3) than in moderate (4.3) or severe TBI (4.0; p = 0.004. In the TRACK-TBI cohort, the 75 (71.4%) subjects with very low BDNF values (i.e., prognostic information regarding recovery from TBI. Thus, day

    Bacterial invasion in subgingival sites especially of gram-negative organisms are initiators for periodontal diseases. The periodontal pathogens with persistent inflammation lead to destruction of periodontium. In recent years, periodontal diseases have been associated with a number of systemic diseases such as rheumatoid arthritis, cardiovascular-disease, diabetes mellitus, chronic respiratory diseases and adverse pregnancy outcomes including pre-term low-birth weight (PLBW) and pre-eclampsia. The factors like low socio-economic status, mother's age, race, multiple births, tobacco and drug-abuse may be found to increase risk of adverse pregnancy outcome. However, the same are less correlated with PLBW cases. Even the invasion of both aerobic and anerobic may lead to inflammation of gastrointestinal tract and vagina hence contributing to PLBW. The biological mechanism involved between PLBW and Maternal periodontitis is the translocation of chemical mediators of inflammation. Pre-eclampsia is one of the commonest cause of both maternal and fetal morbidity as it is characterized by hypertension and hyperprotenuria. Improving periodontal health before or during pregnancy may prevent or reduce the occurrences of these adverse pregnancy outcomes and, therefore, reduce the maternal and perinatal morbidity and mortality. Hence, this article is an attempt to review the relationship between periodontal condition and altered pregnancy outcome. PMID:26229389

    Adverse childhood experiences (ACEs) can affect people's health and wellbeing not only at the time the ACE is experienced, but also later in life. The majority of studies on ACEs are carried out in high-income countries and little is known about its prevalence in low and middle-income countries. Thus, the aim of this study was to assess the prevalence of ACEs, associations between ACEs and sociodemographic factors, and the interrelationship between types of ACEs in adolescents of a Brazilian birth cohort. Data from 3,951 adolescents (78.4% of the original cohort) from the 1993 Pelotas Cohort were analyzed. Seven types of ACEs were assessed in those up to 18 years old: physical abuse, sexual abuse, physical neglect, emotional neglect, domestic violence, parental separation and parental death. The most common ACE was parental separation (42%), followed by emotional neglect (19.7%) and domestic violence (10.3%). Approximately 85% of the adolescents experienced at least one ACE, and females reported a higher number of adversities. Several socioeconomic, demographic and family-related characteristics were associated with the occurrence of ACEs, e.g. non-white skin color, low family income, low maternal schooling, absence of mother's partner, maternal smoking, and poor maternal mental health. A strong interrelationship was observed among the ACEs, indicating clustering of risk. These aspects should be considered by health and social care professionals in the prevention and identification of childhood adversities. PMID:26707919

    The causal factors of accidents from the National Transportation Safety Board (NTSB) database and incidents from the Federal Aviation Administration (FAA) database associated with loss of control (LOC) were examined for four types of operations (i.e., Federal Aviation Regulation Part 121, Part 135 Scheduled, Part 135 Nonscheduled, and Part 91) for the years 1988 to 2004. In-flight LOC is a serious aviation problem. Well over half of the LOC accidents included at least one fatality (80 percent in Part 121), and roughly half of all aviation fatalities in the studied time period occurred in conjunction with LOC. An adverse events table was updated to provide focus to the technology validation strategy of the Integrated Resilient Aircraft Control (IRAC) Project. The table contains three types of adverse conditions: failure, damage, and upset. Thirteen different adverse condition subtypes were gleaned from the Aviation Safety Reporting System (ASRS), the FAA Accident and Incident database, and the NTSB database. The severity and frequency of the damage conditions, initial test conditions, and milestones references are also provided.

    Objective In breast cancer, several tumor markers have been identified. The marker most extensively associated with breast cancer is MUC1. The objective of the study was to analyze prognostic and risk factors in relation to tumor markers in order to clarify breast cancer biology. A total of 349 primary tumor samples and lymph nodes from breast cancer patients were studied. Risk and prognostic factors were considered. An immunohistochemical approach was applied and an extensive statistical analysis was performed, including frequency analysis and analysis of variance. Correlation among variables was performed with principal component analysis. Results All the antigens showed an increased expression according to tumor size increment; moreover, sialyl Lewis x expression showed a significant increase in relation to disease stage, whereas Tn and TF presented a positive tendency. Vascular invasion was related to sialyl Lewis x expression and number of metastatic lymph nodes. Taking into account risk factors, when a patient had at least one child, Lewis antigens diminished their expression. In relation to breastfeeding, sialyl Lewis x expression diminished, although its apical expression increased. Conclusion Associations between MUC1 and carbohydrate antigens and risk and prognostic factors show the complexity of the cellular biological behavior that these antigens modulate in breast cancer.

    Hepatoma-derived growth factor (HDGF) is a unique nuclear/growth factor that plays an important role in the progression of different types of cancer. A total of 63 patients with early-stage cervical adenocarcinoma (Cx) were enrolled in this retrospective study. The expression of HDGF was significantly increased compared with adjacent non-tumor tissue samples (p < 0.001). Moreover, elevated nuclear HDGF levels were correlated with lymph-vascular space invasion (LVSI; p < 0.05), lymph node metastasis (LNM; p < 0.001), recurrence (p < 0.001) and advanced grade (AG; p < 0.001). The growth of cervical cancer cells (Hela cells) was enhanced by HDGF treatment. The HDGF mRNA and protein level were significantly higher in malignant cervical cancer cells compared with primary ones. By adenovirus gene delivery, HDGF overexpression enhanced, whereas HDGF knockdown perturbed the tumorigenic behaviors of cervical cancer cells. HDGF overexpression is common in early-stage cervical adenocarcinoma and is involved in the carcinogenesis of cervical adenocarcinoma. Cytoplasmic HDGF expression is strongly correlated with pelvic lymph node metastasis and recurrence, indicating that HDGF may serve as a novel prognostic marker for patients with Cx.

    Most of the traditional parameters for nutrition assessment have important limitations in patients with chronic liver disease. Insulin-like growth factor 1 (IGF-1) has been found to be regulated by nutrition and proposed as a nutritional marker. Its nutritional significance in patients with liver cirrhosis, however, has not been investigated. Serum IGF-1 as well as traditional anthropometric, visceral, and immunologic parameters were evaluated in 64 hospitalized cirrhotics, followed up clinically for 2 y. IGF-1Z-score averaged -2.16 +/- 1.08 and inversely correlated with Child-Pugh score (P < 0.01), the most reliable composite score reflecting the severity of liver disease. IGF-1Z-score was not different in patients with or without signs of energy malnutrition, as defined by values of midarm muscle circumference (MAMC) and/or triceps skinfold (TSF) < 5th percentile. Moreover, IGF-1Z-score did not correlate with MAMC or TSF. Despite its correlation with all visceral proteins, the reduction of IGF-1 was much greater and more frequent than that of visceral proteins. Patients with IGF-1Z-score < median values (-2.5) showed lower long-term survival rates compared with patients with IGF-1Z-score > -2.5 (P < 0.01). These data indicate that serum IGF-1 is not related to energy malnutrition in cirrhotic patients, while it appears to be a good predictor of survival and an early marker of liver dysfunction. Multiple factors, most of which are related to the severity of the liver disease, may contribute to the reduction of IGF-1. This multifactorial pathogenesis probably accounts for its prognostic significance. PMID:9131676

    We used to LASSO-Cox method for determining prognostic factors of male breast cancer survival and showed the superiority of this method compared to Cox proportional hazard model in low sample size setting. In order to identify and estimate exactly the relative hazard of the most important factors effective for the survival duration of male breast cancer, the LASSO-Cox method has been used. Our data includes the information of male breast cancer patients in Fars province, south of Iran, from 1989 to 2008. Cox proportional hazard and LASSO-Cox models were fitted for 20 classified variables. To reduce the impact of missing data, the multiple imputation method was used 20 times through the Markov chain Mont Carlo method and the results were combined with Rubin's rules. In 50 patients, the age at diagnosis was 59.6 (SD=12.8) years with a minimum of 34 and maximum of 84 years and the mean of survival time was 62 months. Three, 5 and 10 year survival were 92%, 77% and 26%, respectively. Using the LASSO-Cox method led to eliminating 8 low effect variables and also decreased the standard error by 2.5 to 7 times. The relative efficiency of LASSO-Cox method compared with the Cox proportional hazard method was calculated as 22.39. The19 years follow of male breast cancer patients show that the age, having a history of alcohol use, nipple discharge, laterality, histological grade and duration of symptoms were the most important variables that have played an effective role in the patient's survival. In such situations, estimating the coefficients by LASSO-Cox method will be more efficient than the Cox's proportional hazard method. PMID:26434910

    Objective Pulmonary edema is frequently observed after a successful resuscitation in out-of-hospital cardiac arrest (OHCA) patients. Currently, its risk factors and prognostic implications are mostly unknown. Methods Adult OHCA patients with a presumed cardiac etiology who achieved sustained return of spontaneous circulation (ROSC) in emergency department were retrospectively analyzed. The patients were grouped according to the severity of consolidation on their initial chest X-ray (group I, no consolidation; group II, patchy consolidations; group III, consolidation involving an entire lobe; group IV, total white-out of any lung). The primary objective was to identify the risk factors of developing severe pulmonary edema (group III or IV). The secondary objective was to evaluate the association between long-term prognosis and the severity of pulmonary edema. Results One hundred and seven patients were included. Total duration of cardiopulmonary resuscitation (CPR) and initial pCO2 level were both independent predictors of developing severe pulmonary edema with their odds ratio (OR) being 1.02 (95% confidence interval [CI], 1.00 to 1.04; per 1 minute) and 1.04 (95% CI, 1.01 to 1.07; per 1 mmHg), respectively. The long term prognosis was significantly poor in patients with severe pulmonary edema with a OR for good outcome (6-month cerebral performance category 1 or 2) being 0.22 (95% CI, 0.06 to 0.79) in group III and 0.16 (95% CI, 0.04 to 0.63) in group IV compared to group I. Conclusion The duration of CPR and initial pCO2 level were both independent predictors for the development of severe pulmonary edema after resuscitation in emergency department. The severity of the pulmonary edema was significantly associated with long-term outcome.

    CTLA-4 function as a negative regulator of T cell-mediated immune response is well established, whereas much less is known about the immunoregulatory role of its soluble isoform (sCTLA-4). No data are available on CTLA-4 expression and prognostic impact in malignant pleural mesothelioma (MPM). We investigated, by immunohistochemistry, CTLA-4 expression in tumor tissues and, by ELISA, sCTLA-4 levels in sera and matched pleural effusions from 45 MPM patients. Prognostic effect of CTLA-4 expression on overall survival (OS) was assessed through Cox regression and prognostic significance expressed as death rate ratio (HR). We found that 56.0 % of MPM tissues expressed CTLA-4 with variable intensity and percentage of positive cells estimated by the immunoreactive score. sCTLA-4 levels were significantly higher in sera (S-sCTLA-4) than in pleural effusions (PE-sCTLA-4) (geometric mean ratio = 2.70, P value = 0.020). CTLA-4 expression at the tissue level was higher in the epithelioid histological subtype than in the sarcomatoid, whereas at the serum level, it was higher in the sarcomatoid subtype. A homogeneous favorable prognostic effect was found for CTLA-4 overexpression in tissue, serum and pleural effusion. Interestingly, only the PE-sCTLA-4 was found to be a statistically significant positive prognostic factor (HR = 0.37, 95 % CI = 0.18-0.77, P value = 0.007). Indeed, PE-sCTLA-4 correlated with CTLA-4 expression in tissues, whereas this latter expression showed a weak association with OS. To confirm our findings, further experimental evidences obtained from a larger cohort of MPM patients are required. However, our results would indicate a positive correlation of PE-sCTLA-4 levels and OS in MPM patients.

    Background The ABO blood group is reported to be associated with the incidence and patient survival for several types of malignancies. We conducted a retrospective study to evaluate the prognostic significance of the ABO blood group in patients with resected non-small cell lung cancer (NSCLC). Methods A total of 333 patients (218 men and 115 women) with resected NSCLC were included in this study. In addition to age, sex, smoking status, preoperative serum carcinoembryonic antigen (CEA) level, operative procedure, histology of tumors, pathological stage (p-stage), and adjuvant therapy, the association between the ABO blood group and survival was explored. Results The 5-year overall and disease-free survival rates were 83.0% and 71.6% for blood group O, 67.2% and 62.3% for blood group A, 68.8% and 68.8% for blood group B and 69.2% and 65.3% for blood group AB, respectively. A multivariate analysis for overall survival showed the ABO blood group (group A vs. group O: HR 2.47, group AB vs. group O: HR 3.62) to be an independent significant prognostic factor, in addition to age, sex, smoking status, p-stage, and serum CEA level. A multivariate analysis for disease-free survival also showed the ABO blood group to be an independent significant prognostic factor. Conclusions The ABO blood group is an independent prognostic factor in patients with resected NSCLC. Studies of other larger cohorts are therefore needed to confirm the relationship between the ABO blood group and the prognosis among patients with resected NSCLC. PMID:25483106

    Growing evidence supports a link between fatty acid metabolism and amyotrophic lateral sclerosis (ALS). Here we determined the fatty acid composition of blood lipids to identify markers of disease progression and survival. We enrolled 117 patients from two clinical centers and 48 of these were age and gender matched with healthy volunteers. We extracted total lipids from serum and blood cells, and separated fatty acid methyl esters by gas chromatography. We measured circulating biochemical parameters indicative of the metabolic status. Association between fatty acid composition and clinical readouts was studied, including ALS functional rating scale-revised (ALSFRS-R), survival, disease duration, site of onset and body mass index. Palmitoleate (16:1) and oleate (18:1) levels, and stearoyl-CoA desaturase indices (16:1/16:0 and 18:1/18:0) significantly increased in blood cells from ALS patients compared to healthy controls. Palmitoleate levels and 16:1/16:0 ratio in blood cells, but not body mass index or leptin concentrations, negatively correlated with ALSFRS-R decline over a six-month period (p<0.05). Multivariate Cox analysis, with age, body mass index, site of onset and ALSFRS-R as covariables, showed that blood cell 16:1/16:0 ratio was an independent prognostic factor for survival (hazard ratio=0.1 per unit of ratio, 95% confidence interval=0.01-0.57, p=0.009). In patients with high 16:1/16:0 ratio, survival at blood collection was extended by 10 months, as compared to patients with low ratio. The 16:1/16:0 index is an easy-to-handle parameter that predicts survival of ALS patients independently of body mass index. It therefore deserves further validation in larger cohorts for being used to assess disease outcome and effects of disease-modifying drugs. PMID:26147510

    Objective In this study we aimed to evaluate prognostic factors for the survival of patients with Fournier’s gangrene (FG), and overview different validated scoring systems for outcome prediction. Material and methods We retrospectively analyzed the data of 39 patients treated for FG in our clinic. Data were collected on medical history, symptoms, physical examination findings, vital signs, laboratory parameters at admission and at the end of treatment, timing and extent of surgical debridement, and the antibiotic treatment used. The Fournier’s Gangrene Severity Index (FGSI) and Charlson Comorbidity Index (CCI) were used to predict outcome. The data were analyzed in relation with the survival of the patients. Mann-Whitney U test, chi -square test, Wilcoxon signed rank test, and Cox regression analysis were used for the statistical analysis. Results Of 39 patients analyzed, 8 (20.5%) died and 31 (79.5%) survived. The median FGSI score on admission was 2 (0–9) for the survivors and 6 (2–14) for the non-survivors (p=0.004). The median CCI scores of the survivors and non-survivors were 2 (0–10) and 6.5 (5–11), respectively (p=0.001). Except for urea, albumin and hematocrit levels, no significant differences were found between survivors and non-survivors for other laboratory parameters on admission. Lower albumin levels and advanced age were found to be associated with mortality. Conclusion High blood urea, low albumin, and low hematocrit levels were associated with poor prognosis. High CCI and FGSI scores could be associated with a poor prognosis in patients with FG.

    Nosocomial infections are an important cause of preventable morbidity and mortality; they also result in significant socioeconomic cost. Nosocomial pneumonia (NCP) is defined as pneumonia, which occurs 48 hours after hospitalization or after discharge from the hospital. It is the second or third most frequent infection among all hospital acquired infections, and the mortality of NCP is higher than the other hospital acquired infections. Patients, diagnosed as NCP were retrospectively analyzed in order to detect microbiological agent and prognostic factors. We evaluated 173 patients, 67.0% of them were male and 33.0% female. Comorbid diseases were present in 94.2% and a medical procedure had been applied in 75.1% of cases. A single agent was isolated in 79.2% of the cases while a mixt infection was present in 13.3%. In 7.5% of the cases, cultures were negative. Endotracheal aspirates were the most common materials (38.9%) used for detected microorganism and sputum cultures were used in 16.8% of the cases. Most commonly encountered microorganism were Pseudomonas aeruginosa, Acinetobacter spp. and Staphylococcus aureus respectively. NCP developed on approximately 18th day of hospitalization. Overall mortality rate was 45.2%. The effects of diabetes mellitus and chronic pulmonary diseases on mortality rate were analized by logistic regression analysis and it's evaluated that the mortality rates increase 3.7 times with diabetes mellitus and 2.4 times with chronic pulmonary diseases. There was no effect of mechanical ventilation history on mortality. PMID:17602343

    Purpose To investigate the outcomes of pars plana vitrectomy (PPV) for chronic diabetic traction macular detachment (CTMD). Methods Ninety-six eyes that underwent PPV for CTMD of at least 6 months duration were retrospectively analyzed. Retinal reattachment rate, final vision, and prognostic factors for poor visual outcome were the main outcome measures. Results All eyes had long-standing TMD (median 12, range: 6–70 months). The median postoperative follow-up was 15 (range: 3–65) months. Eighty-seven eyes (90.6%) had their retina and macula reattached after one PPV. At final examination, 84 eyes (87.5%) had stable vision or at least one line improvement, and three had no light perception. Seventeen (17.7%) and 41 (43%) eyes had preoperative visual acuity of ≥20/200 and ≥5/200 as compared to 40 (41.6%; P=0.0005) and 64 (66.7%; P=0.0014) eyes at final follow-up, respectively. Age >50 years (Odds ratio [OR] =5.84, 95% confidence interval [CI] =1.53–22.19, P=0.01), preoperative vision <20/400 (OR =7.012, 95% CI =1.82–26.93, P=0.005), and ischemic macula (OR =14.13, 95% CI =3.61–55.33, P<0.001) were significantly associated with final vision <20/400. Conclusion PPV for CTMD may be beneficial particularly in patients who are relatively younger and have good baseline vision and no macular ischemia.

    2010-01-01

    Background Desmoplasia in medulloblastoma is often diagnosed in adult patients and was repeatedly associated with improved results. Today, all medulloblastoma patients receive intensive multimodal treatment including surgery, radiotherapy and chemotherapy. This study was set up to investigate treatment outcome and prognostic factors after radiation therapy in patients with desmoplastic medulloblastomas. Methods Twenty patients treated for desmoplastic medulloblastoma in the Department of Radiation Oncology at the University of Heidelberg between 1984 and 2007 were included. Data were collected retrospectively. Tumor resection was performed in all patients. All patients underwent postsurgical radiotherapy (RT). Two patients underwent whole brain radiotherapy (WBRT), and 18 patients received craniospinal irradiation (CSI). In all patients, an additional boost was delivered to the posterior fossa. The median dose to the whole brain and the craniospinal axis was 35.2 Gray (Gy), and 54.4 Gy to the posterior fossa. Fourteen patients received chemotherapy, including seven who were treated with combined radiochemotherapy and twelve who received adjuvant chemotherapy. Statistical analysis was performed using the log-rank test and the Kaplan-Meier method. Results Median follow-up was 59 months. Overall (OS), local (LPFS) and distant progression-free survival (DPFS) was 80%, 71.2%, and 83.3% at 60 months. Patients who suffered from local or distant relapses had significantly worse outcome. Five patients died from recurrent medulloblastoma. Treatment-associated toxicity was acceptable. Conclusions Multimodal approaches with surgical resection followed by chemoirradiation achieved high response rates with long OS in desmoplastic medulloblastoma patients. Staging parameters expected to predict for poor prognosis did not significantly influence outcome. However, success of any first line regimen had strong impact on disease control, and remission was achieved in no patient with

    Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical syndrome characterized by the activation of the mononuclear phagocytic system. The diagnosis of HLH in adults is challenging not only because the majority of the reported data are from pediatric patients, but also because HLH occurs in many disease entities. This study reports the clinical and laboratory findings and prognostic factors of adult HLH in a large cohort managed at a single medical center from 2003 to 2014. Seventy-three patients met the HLH-2004 diagnostic criteria. The median age was 51 years (range, 18-82 years); 41 (56.2%) were male. Patients manifested fever, cytopenias, and elevated ferritin in >85% of cases. Likely causes of HLH were as follows: 30 (41.1%) infections, 21 (28.8%) malignancies, 5 (6.8%) attributed to autoimmune disorders, 1 (1.4%) primary immunodeficiency, 2 (2.7%) post solid organ transplantation, and 13 (17.8%) idiopathic. The median overall survival was 7.67 months. Patients with malignancy-associated HLH had a markedly worse survival compared with patients with non-malignancy-associated HLH (median overall survival 1.13 vs. 46.53 months, respectively; P < 0.0001). In a multivariable analysis, malignancy (hazard ratio = 12.22; 95% CI: 2.53-59.02; P = 0.002) correlated with poor survival. Ferritin >50,000 µg/L correlated with 30-day mortality. Survival after a diagnosis of HLH is dismal, especially among those with malignancy-associated HLH. The development of a registry for adults with HLH would improve our understanding of this syndrome, validate diagnostic criteria, and help develop effective treatment strategies. PMID:25469675

    Purpose To investigate the outcomes of pars plana vitrectomy (PPV) for chronic diabetic traction macular detachment (CTMD). Methods Ninety-six eyes that underwent PPV for CTMD of at least 6 months duration were retrospectively analyzed. Retinal reattachment rate, final vision, and prognostic factors for poor visual outcome were the main outcome measures. Results All eyes had long-standing TMD (median 12, range: 6–70 months). The median postoperative follow-up was 15 (range: 3–65) months. Eighty-seven eyes (90.6%) had their retina and macula reattached after one PPV. At final examination, 84 eyes (87.5%) had stable vision or at least one line improvement, and three had no light perception. Seventeen (17.7%) and 41 (43%) eyes had preoperative visual acuity of ≥20/200 and ≥5/200 as compared to 40 (41.6%; P=0.0005) and 64 (66.7%; P=0.0014) eyes at final follow-up, respectively. Age >50 years (Odds ratio [OR] =5.84, 95% confidence interval [CI] =1.53–22.19, P=0.01), preoperative vision <20/400 (OR =7.012, 95% CI =1.82–26.93, P=0.005), and ischemic macula (OR =14.13, 95% CI =3.61–55.33, P<0.001) were significantly associated with final vision <20/400. Conclusion PPV for CTMD may be beneficial particularly in patients who are relatively younger and have good baseline vision and no macular ischemia. PMID:27616879

    Ovarian cancer remains the most lethal gynecologic cancer and new targeted molecular therapies against this miserable disease continue to be challenging. In this study, we analyzed the expressional patterns of Interleukin-6 (IL-6) and its receptor (IL-6R) expression in ovarian cancer tissues, evaluated the impact of these expressions on clinical outcomes of patients, and found that a high-level of IL-6R expression but not IL-6 expression in cancer cells is an independent prognostic factor. In in vitro analyses using ovarian cell lines, while six (RMUG-S, RMG-1, OVISE, A2780, SKOV3ip1 and OVCAR-3) of seven overexpressed IL-6R compared with a primary normal ovarian surface epithelium, only two (RMG-1, OVISE) of seven cell lines overexpressed IL-6, suggesting that IL-6/IL-6R signaling exerts in a paracrine manner in certain types of ovarian cancer cells. Ovarian cancer ascites were collected from patients, and we found that primary CD11b+CD14+ cells, which were predominantly M2-polarized macrophages, are the major source of IL-6 production in an ovarian cancer microenvironment. When CD11b+CD14+ cells were co-cultured with cancer cells, both the invasion and the proliferation of cancer cells were robustly promoted and these promotions were almost completely inhibited by pretreatment with anti-IL-6R antibody (tocilizumab). The data presented herein suggest a rationale for anti-IL-6/IL-6R therapy to suppress the peritoneal spread of ovarian cancer, and represent evidence of the therapeutic potential of anti-IL-6R therapy for ovarian cancer treatment.

    Objective In this study we aimed to evaluate prognostic factors for the survival of patients with Fournier’s gangrene (FG), and overview different validated scoring systems for outcome prediction. Material and methods We retrospectively analyzed the data of 39 patients treated for FG in our clinic. Data were collected on medical history, symptoms, physical examination findings, vital signs, laboratory parameters at admission and at the end of treatment, timing and extent of surgical debridement, and the antibiotic treatment used. The Fournier’s Gangrene Severity Index (FGSI) and Charlson Comorbidity Index (CCI) were used to predict outcome. The data were analyzed in relation with the survival of the patients. Mann-Whitney U test, chi -square test, Wilcoxon signed rank test, and Cox regression analysis were used for the statistical analysis. Results Of 39 patients analyzed, 8 (20.5%) died and 31 (79.5%) survived. The median FGSI score on admission was 2 (0–9) for the survivors and 6 (2–14) for the non-survivors (p=0.004). The median CCI scores of the survivors and non-survivors were 2 (0–10) and 6.5 (5–11), respectively (p=0.001). Except for urea, albumin and hematocrit levels, no significant differences were found between survivors and non-survivors for other laboratory parameters on admission. Lower albumin levels and advanced age were found to be associated with mortality. Conclusion High blood urea, low albumin, and low hematocrit levels were associated with poor prognosis. High CCI and FGSI scores could be associated with a poor prognosis in patients with FG. PMID:27635295

    Purpose: To retrospectively evaluate the prognostic factors and survival of a series of 777 patients with brain metastases (BM) from a single institution. Methods and Materials: Patients were treated with surgery followed by whole-brain radiation therapy (WBRT) or with WBRT alone in 16.3% and 83.7% of the cases, respectively. The patients were RPA (recursive partitioning analysis) class I, II, and III in 11.2%, 69.6%, and 18.4% of the cases, respectively; RPA class II-a, II-b, and II-c in 8.3%, 24.8%, and 66.9% of the cases, respectively; and with GPA (graded prognostic assessment) scores of 0-1.0, 1.5-2.0, 2.5-3.0, and 3.5-4.0 in 35%, 27.5%, 18.2%, and 8.6% of the cases, respectively. Results: The median overall survival (OS) times according to RPA class I, II, and III were 20.1, 5.1, and 1.3 months, respectively (P<.0001); according to RPA class II-a, II-b, II-c: 9.1, 8.9, and 4.0 months, respectively (P<.0001); and according to GPA score 0-1.0, 1.5-2.0, 2.5-3.0, and 3.5-4.0: 2.5, 4.4, 9.0, and 19.1 months, respectively (P<.0001). By multivariate analysis, the favorable independent prognostic factors for survival were as follows: for gastrointestinal tumor, a high Karnofsky performance status (KPS) (P=.0003) and an absence of extracranial metastases (ECM) (P=.003); for kidney cancer, few BM (P=.002); for melanoma, few BM (P=.01), an absence of ECM (P=.002), and few ECM (P=.0002); for lung cancer, age (P=.007), a high KPS (P<.0001), an absence of ECM (P<.0001), few ECM and BM (P<.0001 and P=.0006, respectively), and control of the primary tumor (P=.004); and for breast cancer, age (P=.001), a high KPS (P=.007), control of the primary tumor (P=.05), and few ECM and BM (P=.01 and P=.0002, respectively). The triple-negative subtype was a significant unfavorable factor (P=.007). Conclusion: Prognostic factors varied by pathology. Our analysis confirms the strength of prognostic factors used to determine the GPA score, including the genetic subtype for breast cancer.

    Pancreatic ductal adenocarcinoma (PDAC) has a poor 5-year survival rate of 5%. Biomarkers for the early detection of pancreatic cancer are urgently needed. Transforming growth factor-beta1 (TGF-β1) is elevated in the tissues and plasma of patients with PDAC. However, no studies systemically report prognostic significance of plasma TGF-β1 levels in PDAC. In the present study, we assessed the prognostic significance of serum TGF-β levels in patients with PDAC. TGF-β levels were determined in serum from 146 PDAC patients, and 58 patients with benign pancreatic conditions. Regression models were used to correlate TGF-β levels to gender, age, stage, class, and metastasis. Survival analyses were performed using multivariate Cox models. Serum levels of TGF-β1 distinguished PDAC from benign pancreatic conditions (P<0.001) and healthy control subjects (P<0.001). Serum levels of TGF-β also distinguished tumor stage (P=0.002) and lymph node metastasis (P=0.001). High serum levels of TGF-β1 were significantly correlated with reduced patient survival. Multivariate analysis revealed that TGF-β1, lymph node metastasis and tumor stage were independent factors for PDAC survival. Our results indicate that serum TGF-β1 may be used as a potential prognostic marker for PDAC. PMID:27464025

    Immune suppression is a hallmark of multiple myeloma (MM), but data on soluble factors involved in the fate of immune effector cells are limited. The CXCR3-binding chemokine monokine induced by interferon-gamma (MIG/CXCL9) has been associated with tumor progression, immune escape, and angiogenesis in several malignancies. We here aimed to evaluate the prognostic relevance of MIG in MM. MIG serum levels were significantly elevated in newly diagnosed MM patients (n = 105) compared to patients with monoclonal gammopathy of undetermined significance (MGUS; n = 17) and healthy controls (n = 37). MIG expression in stromal compartments but not purified MM cells correlated with serum levels. High MIG serum levels were significantly associated with established prognostic markers (international staging system: R = 0.25, p = 0.001; age: R = 0.47, p < 0.0001; lactate-dehydrogenase: R = 0.34, p = 0.0005) and poor overall survival (OS) (median OS 17.0 months vs. not reached, p < 0.001). A similar association was found for CXCL10 and CXCL11. Multivariate regression analysis indicated MIG as an independent prognostic factor of OS. PMID:26999330

    The primary objective of this study is to review the clinical characteristics of 25 patients in the adult and late adolescent age group, diagnosed and treated with small round cell tumors involving soft tissues (extraosseous Ewing sarcoma, rhabdo-myosarcoma, primitive neuroectodermal tumor, and undiffer-entiated small round cell tumors). Additionally, survival and prognostic factors influencing the outcome with multimodality treatment are evaluated. There were 19 males (76%) and 6 females (24%). The median age was 26 years (range: 15-56 years). In 9 patients (36%), the tumor was located at an extremity, whereas 16 patients (64%) had central localizations. Tumor size was larger than 10 cm in 7 patients (29.2%). Six patients (24%) had metastatic disease. Twelve patients (48%) received radiation and 16 patients (64%) underwent surgery. Among the resected tumors, 2 were resected with contaminated margins (12.5%), whereas 2 were radically resected and 12 (75%) were resected with wide margins. All patients were given a median of 4 cycles of multiagent chemotherapy (1-14 cycles). With preoperative chemotherapy, complete regression (CR) of the tumor was achieved in 6 patients (24%). In 4 patients (16%), a partial response was obtained. After the completion of multimodality treatment, 12 patients (48%) had a CR. Progression-free (PFS) and overall survival (OS) for the entire group was 25.0 +/- 10.8% at 1 year and 30.5 +/- 15.5% at 3 years, respectively. Nonmetastatic disease, wide and radical resection, and presence of CR to multimodality treatment were associated with a significantly longer PFS and OS by univariate analysis. By multivariate analysis, CR to multimodality treat-ment was the only independent predictive factor for a longer OS (p: 0.0036, relative risk [RR]: 23.6, 95% CI: 2.8; 198.7) and metastatic presentation was the only independent factor predic-tive for a shorter PFS (p: 0.017, RR. 15, 95% CI: 1.6; 141.2).

In this review, the basic risk factors of vascular complications in diabetes mellitus are described and their prognostic value analysed. Special attention is paid to the evaluation of the role of adipose tissue hormone adiponectin. The anti-inflammatory properties of adiponectin suggest its protective action against atherosclerosis and cardiovascular complications. In this article, we review a number of studies on the relationship between adiponectin and the main cardiovascular risk factors in patients with type 2 diabetes mellitus.

    pS2 protein assay was performed with Elsa-pS2 kit (CIS-Biointernational) on a group of 1,065 patients with operable breast cancer who underwent breast surgery in the years 1982 through 1990. The median follow-up was 57 months. This group included exclusively infiltrating ductal carcinoma with primary surgery. Age mean was 58 yr; T0-T1, 33.6%; T2-T4, 66.4%; Differentiation grade I, 29%; node negative, 53%; estrogen receptor (ER) positive, 62.4%; progesterone receptor (PR) positive, 55.2%; mean tumor size, 2.4 cm; local recurrence, 5.2%; metastasis, 17.5%. pS2 values varied from 0.1 to 707 ng/mg of cytosol protein (median, 5.6; mean 24.5; 95th percentile 112 ng/mg p). There was no significant relationship between the mean level of pS2 and age, tumor size, nodal status, whereas pS2 was related to histological grade (P < 10(-3)), ER (P < 10(-5)), and PR (P < 10(-5)). By using 2 ng/mg p as pS2 cutoff, 77/391 (19.7%) of ER+PR+ tumors were pS2-, and 122/345 (35.4%) of ER-PR-tumors were pS2+; with this cutoff, a strong relationship existed between pS2 and overall survival, but not between pS2 and relapse-free survival. With Cox multivariate analysis, pS2 protein was classified after lymph node status, histological size, ER, differentiation grade, age, clinical stage, PR. In patients with axillary lymph node involvement (N+), pS2 status could discriminate between good and bad prognosis, specially for patients with small tumors (< 2 cm) and with less than seven invaded nodes. This study showed that pS2 protein was a poor prognostic factor in comparison with classical factors.

    Repeated subcutaneous (s.c.) injection is a common route of administration in chronic studies of neuroactive compounds. However, in a pilot study we noted a significant incidence of skin abnormalities in adult male Long-Evans rats receiving daily s.c. injections of peanut oil (1.0 ml/kg) in the subscapular region for 21 d. Histopathological analyses of the lesions were consistent with a foreign body reaction. Subsequent studies were conducted to determine factors that influenced the incidence or severity of skin abnormalities, and whether these adverse skin reactions influenced a specific neurobehavioral outcome. Rats injected daily for 21 d with food grade peanut oil had an earlier onset and greater incidence of skin abnormalities relative to rats receiving an equal volume (1.0 ml/kg/d) of reagent grade peanut oil or triglyceride of coconut oil. Skin abnormalities in animals injected daily with peanut oil were increased in animals housed on corncob versus paper bedding. Comparison of animals obtained from different barrier facilities exposed to the same injection paradigm (reagent grade peanut oil, 1.0 ml/kg/d s.c.) revealed significant differences in the severity of skin abnormalities. However, animals from different barrier facilities did not perform differently in a Pavlovian fear conditioning task. Collectively, these data suggest that environmental factors influence the incidence and severity of skin abnormalities following repeated s.c. injections, but that these adverse skin responses do not significantly influence performance in at least one test of learning and memory.

    Mucoepidermoid carcinoma (MEC) is an infrequent malignant neoplasm that originates most commonly in the salivary glands. The present study aimed to provide new information on prognostic factors in patients with salivary gland MEC. A retrospective analysis of the medical records of patients diagnosed with primary salivary gland MEC between 2003 and 2010 was conducted. The incidence of MEC in the minor salivary glands (62.2%) was almost twice that in the major salivary glands (37.8%). The most frequently affected sites were the parotid gland and palate. Lymph node metastasis was reported more frequently in male than female patients (P = 0.02), in high-grade than low/intermediate grade lesions (P < 0.001), and in lesions involving the submandibular gland (P < 0.001). The disease-free survival (DFS) at 5 years was 80.47%, with rates of 98.0%, 86.5%, and 38.5% for low-, intermediate-, and high-grade tumours, respectively. Among various clinicopathological factors, the only independent prognostic factor was histological grade (P < 0.001). Primary tumour site and histological grade are two important factors affecting cervical lymph node metastasis. Histological grade is the only independent factor affecting survival beyond tumor lymph node metastasis (TNM) staging in salivary gland MEC. Further advances in therapy are needed to improve the outcomes for patients with high-grade lesions. PMID:24568836

    Proliferative activity, assessed by Ki67 immunohistochemistry (IHC), is an established prognostic and predictive biomarker of breast cancer (BC). However, it remains under-utilized due to lack of standardized robust measurement methodologies and significant intratumor heterogeneity of expression. A recently proposed methodology for IHC biomarker assessment in whole slide images (WSI), based on systematic subsampling of tissue information extracted by digital image analysis (DIA) into hexagonal tiling arrays, enables computation of a comprehensive set of Ki67 indicators, including intratumor variability. In this study, the tiling methodology was applied to assess Ki67 expression in WSI of 152 surgically removed Ki67-stained (on full-face sections) BC specimens and to test which, if any, Ki67 indicators can predict overall survival (OS). Visual Ki67 IHC estimates and conventional clinico-pathologic parameters were also included in the study. Analysis revealed linearly independent intrinsic factors of the Ki67 IHC variance: proliferation (level of expression), disordered texture (entropy), tumor size and Nottingham Prognostic Index, bimodality, and correlation. All visual and DIA-generated indicators of the level of Ki67 expression provided significant cutoff values as single predictors of OS. However, only bimodality indicators (Ashman's D, in particular) were independent predictors of OS in the context of hormone receptor and HER2 status. From this, we conclude that spatial heterogeneity of proliferative tumor activity, measured by DIA of Ki67 IHC expression and analyzed by the hexagonal tiling approach, can serve as an independent prognostic indicator of OS in BC patients that outperforms the prognostic power of the level of proliferative activity.

    Aims—High expression of the angiogenic factor vascular endothelial growth factor (VEGF) in tumours has been found to be associated with poor prognosis in some studies, but not in others. The aims of this study were to determine the prognostic value of VEGF in operable non-small cell lung cancer (NSCLC) and its possible association with vascularity. Methods—Sections from 81 NSCLC archival specimens were stained with antibodies to von Willebrand factor (vWF) and VEGF. Vascularity was measured by the average density of vWF positive vessels. VEGF expression in tumour cells was assessed by consensus of two independent observers according to three indices, namely: (1) percentage of area stained, (2) intensity of staining, and (3) final score (product of area and intensity). Results—VEGF immunoreactivity was present in all tumours and adjacent normal lung tissue. None of the three VEGF indices was associated with vascularity or the clinical parameters examined. Mean survival times were shorter in patients with high VEGF expression, but the difference was not significant. This applied to the full cohort of patients, or when analysed separately according to tumour type or stage. However, high VEGF expression was associated with poor survival in patients with high vascularity (p = 0.02). VEGF had no discriminant value among patients with low vascularity. Vascularity had no prognostic value, except for late stage patients (UICC stages II and IIIa combined; n = 36), where high vascularity was associated with longer survival (p = 0.01). Conclusions—VEGF on its own has no prognostic value in NSCLC, but may become a useful indicator when combined with vascularity. VEGF may play a physiological role in the normal lung.

    INTRODUCTION Temozolomide and concomitant radiotherapy followed by temozolomide has been used as a standard therapy for the treatment of newly diagnosed glioblastoma multiform since 2005. A search for prognostic factors was conducted in patients with glioblastoma routinely treated by this strategy in our institution. METHODS This retrospective study included all patients with histologically proven glioblastoma diagnosed between June 1, 2005, and January 1, 2012, in the Franche-Comté region and treated by radiotherapy (daily fractions of 2 Gy for a total of 60 Gy) combined with temozolomide at a dose of 75 mg/m2 per day, followed by six cycles of maintenance temozolomide (150–200 mg/m2, five consecutive days per month). The primary aim was to identify prognostic factors associated with overall survival (OS) in this cohort of patients. RESULTS One hundred three patients were included in this study. The median age was 64 years. The median OS was 13.7 months (95% confidence interval, 12.5–15.9 months). In multivariate analysis, age over 65 years (hazard ratio [HR] = 1.88; P = 0.01), Medical Research Council (MRC) scale 3–4 (HR = 1.62; P = 0.038), and occurrence of postoperative complications (HR = 2.15; P = 0.028) were associated with unfavorable OS. CONCLUSIONS This study identified three prognostic factors in patients with glioblastoma eligible to the standard chemotherapy and radiotherapy treatment. Age over 65 years, MRC scale 3–4, and occurrence of postoperative complications were associated with unfavorable OS. A simple clinical evaluation including these three factors enables to estimate the patient prognosis. MRC neurological scale could be a useful, quick, and simple measure to assess neurological status in glioblastoma patients. PMID:27559302

    Purpose: To assess the long-term outcomes of patients with rectal cancer who received neoadjuvant chemoradiation therapy (NCRT) with concurrent S-1 and irinotecan (S-1/irinotecan) therapy. Methods and Materials: The study group consisted of 115 patients with clinical stage T3 or T4 rectal cancer. Patients received pelvic radiation therapy (45 Gy) plus concurrent oral S-1/irinotecan. The median follow-up was 60 months. Results: Grade 3 adverse effects occurred in 7 patients (6%), and the completion rate of NCRT was 87%. All 115 patients (100%) were able to undergo R0 surgical resection. Twenty-eight patients (24%) had a pathological complete response (ypCR). At 60 months, the local recurrence-free survival was 93%, disease-free survival (DFS) was 79%, and overall survival (OS) was 80%. On multivariate analysis with a proportional hazards model, ypN2 was the only independent prognostic factor for DFS (P=.0019) and OS (P=.0064) in the study group as a whole. Multivariate analysis was additionally performed for the subgroup of 106 patients with ypN0/1 disease, who had a DFS rate of 85.3%. Both ypT (P=.0065) and tumor location (P=.003) were independent predictors of DFS. A combination of these factors was very strongly related to high risk of recurrence (P<.0001), which occurred most commonly in the lung. Conclusions: NCRT with concurrent S-1/irinotecan produced high response rates and excellent long-term survival, with acceptable adverse effects in patients with rectal cancer. ypN2 is a strong predictor of dismal outcomes, and a combination of ypT and tumor location can identify high-risk patients among those with ypN0/1 disease.

    Objectives: Analyse the effectiveness of different materials and techniques used in guided tissue regeneration (GTR) applied in periapical surgery, comparing the success rate obtained in 4-wall defects and in through-and-through bone lesions as well as to establish prognostic factors. Material and Methods: A Cochrane, PubMed-MEDLINE and Scopus database search (October 2012 to March 2013) was conducted with the search terms “periapical surgery”, “surgical endodontic treatment”, “guided tissue regeneration”, “bone regeneration”, “bone grafts”, “barrier membranes” and “periapical lesions” individually and next, using the Boolean operator “AND”. The inclusion criteria were the use of GTR (bone graft and/or membrane barrier), clinical studies including at least 10 patients, 10 years aged articles published in English or French. The exclusion criteria were case reports and nonhuman studies. Results: 34 publications were selected from a total of 483. 9 of the 34 were excluded. Finally, the systematic review included 25 articles: 2 metaanalysis, 8 reviews, 13 prospective studies and 2 retrospective studies. They were stratified according to their level of scientific evidence using the SORT criteria. The 4-wall periapical and through-and-through lesions improve more their prognosis by combining bone grafts and barrier membranes than using these materials exclusively, respect to the control groups. The results show lower failure rates in 4-wall lesions than in through-and-through lesions using GTR. Conclusions: The combined GTR technique (filling material and membranes) obtains a greater success rate both in 4-wall lesions and in through-and-through lesions, respect to the control groups. The use of regeneration materials seems to be more necessary in through-and-through lesions,> 5mm lesions, lower teeth and apicomarginal lesions as they have the worst healing prognosis.

    The aim of this study was to evaluate the clinical features and the visual results of fireworks-related ocular burn injuries and to determine the prognostic factors. The authors conducted a prospective observational study of 53 eyes of 46 consecutive patients with fireworks-related ocular injury who visited Zhongshan Ophthalmic Center during the Spring Festival in Southern China. Eyes were graded using an ocular trauma classification system, which included age of the patient. Patients were followed up for a minimum of 5 months. Best-corrected visual acuity at the last follow-up was considered the final visual outcome. Data were analyzed with SPSS version 13.0 (SPSS, Inc., Chicago, IL). Results of statistical tests were considered statistically significant for P < .05. Almost all patients (89.1%) were male with a mean age of 14.3 ± 8.5 years. There was preponderance of young patients, with 63.0% (29) of the patients being younger than 15 years. In addition to their ocular injuries, 23 patients (50.0%) also had eyelid and/or facial burns. The most common initial anterior segment injuries were open-globe injuries (42, 79.3%), conjunctival burns (16, 30.2%), and foreign bodies (18, 34.0%). Others were traumatic cataract, lens subluxation and dislocation, and vitreous hemorrhage. Management after first aid included pars plana vitrectomy (9, 17.0%), aspiration of cataract (18, 34.0%), retinal reattachment (8, 15.1%), and enucleation. Amniotic membrane grafts were used in 11 patients (20.8%) with serious conjunctiva burns and corneal contusions and abrasions who were thought to have a good prognosis. Fireworks-related ocular injuries included a variety of clinical manifestations. Examinations such as B scan, optical coherence tomography, and ultrasound biomicroscopy helped to make a correct diagnosis and plan further treatment. Fireworks-related ocular injuries commonly affect young male subjects of Southern China. Visual outcomes were frequently poor and visually

    Background Lowered testosterone level in CRF patients is associated with elevated risk of death due to cardiovascular reasons, and is influenced by many factors, including acid-base balance disorders. Aims: evaluation of testosterone concentration (TT) and free testosterone concentration (fT) in pre-dialysis and dialysis patients; assessment of TT and fT relationships with biochemical parameters; evaluation of prognostic importance of TT and fT in predicting patient survival. Material/Methods 4 groups of men: 14 – on hemodialysis (HD), 13 – on peritoneal dialysis (PD), 9 – with chronic renal failure (CRF) and 8 – healthy (CG), aged 56±17, 53±15, 68±12, 43±10 years, respectively. TT and biochemical parameters were measured; fT was calculated. Results The lowest TT and fT were observed in HD and CRF, the highest – in CG (p=0.035 for TT; p=0.007 for fT). fT in CRF and CG were different (p=0.031). TT and age was associated in HD (p=0.026). Age and fT was strongly associated in PD (p<0.001). After adjustment for age, TT was negatively associated with BMI (p=0.013) and fT was positively associated with HCO3 level (p=0.007). fT was lower in those who died during 5 years of observation than in survivors (p=0.009). We have found that, opposite to TT, fT appeared to be a better predictor of 5-year survival than age. After combining pH and HCO3 levels into a single variable – no acidosis, acidosis with HCO3 normal serum level, acidosis with low concentrations of HCO3 and adjustment for age and the study group – a trend toward the lowest values of free testosterone in decompensated acidosis was observed (ptrend=0.027). Such a trend was not seen for testosterone concentrations (ptrend=0.107). Conclusions Total and free testosterone levels were lower in HD and pre-dialysis than in healthy patients. Free testosterone level may predict long-term survival better than age. Total and free testosterone levels are lower in metabolic acidosis and total and free

    Abstract Published literatures have reported the relationship between hypoxic-inducible factor-2α (HIF-2α) expression and clinicopathological features in gastric cancer (GC), but the evaluated conclusions remain controversial. A meta-analysis was carried to examine the clinicopathological features and prognostic values of HIF-2α in patients with GC. Systematic detailed searches were performed to Pub Med, Cochrane Library, and EBSCO until to August 2015. Six studies (508 specimens) were included in this meta-analysis. HIF-2α-positive expression indicates an unfavorable prognosis value and advanced clinicopathological differences for the available patient dates with GC. Further multivariate meta-analysis revealed that HIF-2α-positive expression in gastric cancer associated with deeper tumor infiltration (OR = 3.08; 95%CI: 1.18–8.04), higher rates of lymphatic metastasis (OR = 3.26; 95%CI: 1.10–9.63), higher TNM stage (III+IV) (OR = 2.61; 95%CI: 1.40–4.84), and much lower 5-year overall survival (OR = 2.08; 95%CI: 1.21–3.58). Nevertheless, there is no association between HIF-2α-positive expression and worse tumor differentiation (OR = 2.03; 95%CI: 0.73–5.64). In addition, by this subgroup analysis, HIF-2α-positive expression associated with deeper tumor infiltration (OR = 3.81; 95%CI: 1.03–14.08), higher lymphatic metastasis (OR = 4.71; 95%CI: 1.08–20.50), higher TNM stage (OR = 3.21; 95%CI: 1.57–6.57), worse tumor differentiation (OR = 3.08; 95%CI: 1.51–6.31), and lower 5-year overall survival (OR = 2.34; 95%CI: 1.15–4.79). Our results indicate that HIF-2α overexpression can potently predict the poor prognosis and may be a potential therapeutic target for gastric carcinoma, according to the limited evidence. Meanwhile, further studies are needed to elucidate the accuracy of these results. PMID:26886654

    Background Non-small cell lung cancer (NSCLC) represents 85% of all lung cancers. It is estimated that 60% of patients with NSCLC at time of diagnosis have advanced disease. The aim of this study was to investigate clinical and demographic prognostic factors of long term survival in patients with unresectable NSCLC. Methods We retrospectively reviewed data of 1,156 patients with NSCLC stage IIIB or IV who survived more than 60 days from the time of diagnosis and treated from August 1987 until March 2013 in the Oncology Department of Pulmonary Clinic of the General Hospital Papanikolaou. Initially univariate analysis using the log-rank test was conducted and then multivariate analysis using the proportional hazards model of Cox. Also Kaplan Meier curves were used to describe the distribution of survival times of patients. The level of significance was set at 0.05. Results The mean age at diagnosis was 62 years. About 11.9% of patients were women and 88.1% were male. The majority of cases were adenocarcinomas (42.2%), followed squamous (33%) and finally the large cell (6%). Unlike men, most common histological type among women was adenocarcinoma rather than squamous (63% vs. 10.9%). In univariate analysis statistically significant factors in the progression free survival (PFS) and overall survival (OS) were: weight loss ≥5%, histological type, line 1 drugs, line 1 combination, line 1 cycles and radio lung. Specifically radio lung gives clear survival benefit in the PFS and OS in stage IIIB (P=0.002) and IV (P<0.001). On the other hand, the number of distant metastases in stage IV patients did not affect OS, neither PFS. In addition patients who received platinum and taxane had better PFS (P=0.001) and OS (P<0.001) than those who received platinum without taxane. Also the third drug administration proved futile, since survival (682.06±34.9) (P=0.023) and PFS (434.93±26.93) (P=0.012) of patients who received less than three drugs was significantly larger.

    The aim of this study was to examine the effect of demographic, socioeconomic, environmental, maternal reproductive, dietary, and nutritional variables on diarrhea risk and prognosis using a hierarchical framework. A case-control study of children aged 0-23 months in Greater Metropolitan Porto Alegre was conducted during the peak season for diarrhea in 1987-1988. Three groups were investigated, with 192 children each. The first group included hospitalized children with an episode of acute diarrhea complicated by moderate to severe dehydration. The second group included children with acute mild diarrhea without signs of dehydration who were identified in the same neighborhood as hospitalized cases. The third group consisted of controls without diarrhea. Mothers were interviewed by trained interviewers using a standardized questionnaire. Data analysis included a hierarchical approach to control for confounding, using conditional logistic regression. Comparison of the three groups aimed to identify risk factors for diarrhea complicated by dehydration, prognostic factors for dehydration, and risk factors for mild diarrhea. Low birth weight, stunting, and lack or breastfeeding acted simultaneously as risk and prognostic factors for diarrhea.

    Purpose: To identify the incidence and the risk factors for pulmonary toxicity in children treated for cancer with contemporary lung irradiation. Methods and Materials: We analyzed clinical features, radiographic findings, pulmonary function tests, and dosimetric parameters of children receiving irradiation to the lung fields over a 10-year period. Results: We identified 109 patients (75 male patients). The median age at irradiation was 13.8 years (range, 0.04-20.9 years). The median follow-up period was 3.4 years. The median prescribed radiation dose was 21 Gy (range, 0.4-64.8 Gy). Pulmonary toxic chemotherapy included bleomycin in 58.7% of patients and cyclophosphamide in 83.5%. The following pulmonary outcomes were identified and the 5-year cumulative incidence after irradiation was determined: pneumonitis, 6%; chronic cough, 10%; pneumonia, 35%; dyspnea, 11%; supplemental oxygen requirement, 2%; radiographic interstitial lung disease, 40%; and chest wall deformity, 12%. One patient died of progressive respiratory failure. Post-irradiation pulmonary function tests available from 44 patients showed evidence of obstructive lung disease (25%), restrictive disease (11%), hyperinflation (32%), and abnormal diffusion capacity (12%). Thoracic surgery, bleomycin, age, mean lung irradiation dose (MLD), maximum lung dose, prescribed dose, and dosimetric parameters between V{sub 22} (volume of lung exposed to a radiation dose ≥22 Gy) and V{sub 30} (volume of lung exposed to a radiation dose ≥30 Gy) were significant for the development of adverse pulmonary outcomes on univariate analysis. MLD, maximum lung dose, and V{sub dose} (percentage of volume of lung receiving the threshold dose or greater) were highly correlated. On multivariate analysis, MLD was the sole significant predictor of adverse pulmonary outcome (P=.01). Conclusions: Significant pulmonary dysfunction occurs in children receiving lung irradiation by contemporary techniques. MLD rather than prescribed

    Influenza viruses cause annual epidemics that occur at different times in both the northern and southern hemisphere. In cases of seasonal influenza these are usually mild forms of the disease, which rarely lead to death of the patient. Vulnerable groups include the elderly, the young or those with comorbidities, where the virus affects tens of thousands of victims around the world. Occasionally, however, large epidemics appear caused by a dangerous variant of a new virus, which is usually characterized by high contagiousness and pathogenicity (virulence). Consequently, it is often accompanied by a complicated disease course and associated with high mortality. In 2009, a viral pandemic disease marked pH1N1 2009 Influenza A appeared. Even though the initial predictions were far worse, the course of influenza caused by this virus was often complicated by acute respiratory failure in the form of acute respiratory distress syndrome (ARDS). This formed part of the wider multiple organ failure syndrome (MODS). This type of virus often infects younger age groups and is more contagious compared to the seasonal flu. In order to illustrate the complicated forms of viral infections pH1N1 2009 Influenza A we present three case studies which demonstrate complicated pulmonary manifestation, which take the primary form of ARDS.

    Purpose We performed a multi-institutional study to identify prognostic factors and determine outcomes for patients with ALK-rearranged non–small-cell lung cancer (NSCLC) and brain metastasis. Patients and Methods A total of 90 patients with brain metastases from ALK-rearranged NSCLC were identified from six institutions; 84 of 90 patients received radiotherapy to the brain (stereotactic radiosurgery [SRS] or whole-brain radiotherapy [WBRT]), and 86 of 90 received tyrosine kinase inhibitor (TKI) therapy. Estimates for overall (OS) and intracranial progression-free survival were determined and clinical prognostic factors were identified by Cox proportional hazards modeling. Results Median OS after development of brain metastases was 49.5 months (95% CI, 29.0 months to not reached), and median intracranial progression-free survival was 11.9 months (95% CI, 10.1 to 18.2 months). Forty-five percent of patients with follow-up had progressive brain metastases at death, and repeated interventions for brain metastases were common. Absence of extracranial metastases, Karnofsky performance score ≥ 90, and no history of TKIs before development of brain metastases were associated with improved survival (P = .003, < .001, and < .001, respectively), whereas a single brain metastasis or initial treatment with SRS versus WBRT were not (P = .633 and .666, respectively). Prognostic factors significant by multivariable analysis were used to describe four patient groups with 2-year OS estimates of 33%, 59%, 76%, and 100%, respectively (P < .001). Conclusion Patients with brain metastases from ALK-rearranged NSCLC treated with radiotherapy (SRS and/or WBRT) and TKIs have prolonged survival, suggesting that interventions to control intracranial disease are critical. The refinement of prognosis for this molecular subtype of NSCLC identifies a population of patients likely to benefit from first-line SRS, close CNS observation, and treatment of emergent CNS disease.

    The number of elderly patients with aneurysmal subarachnoid hemorrhage (SAH) is increasing with the aging of the population. However, management recommendations based on long-term outcome data and analyses of prognostic factors are scarce. Our study focused exclusively on elderly patients aged ≥ 60 years at the onset of SAH. Patients were selected from an in-house database and compared in cohorts of age 60-69, 70-79, and ≥ 80, regarding pre-existing medical conditions, treatment, clinical course including complications, and outcome. A multivariate analysis was conducted to identify prognostic factors for death and disability. A total of 256 patients (138 aged 60-69, 93 aged 70-79, 25 aged ≥ 80) with putative aneurysmal SAH who had been admitted to our hospital between January 1, 1996 and June 30, 2007 were extracted. The median follow-up of our total cohort was 35.5 months (range <1-154 months). Endovascular or conservative aneurysm treatment was applied more often with increasing age (p < 0.006). The 1-year survival rate was 78, 65, and 38 % in the three age groups, respectively (p = 0.0002); most of the patients died from the initial hemorrhage or from medical complications. Patients aged <70 with an initial World Federation of Neurosurgical Societies (WFNS) score of I-III showed the best clinical recovery. WFNS score, age, and clipping/coiling were extracted as prognostic factors from the Cox model. Elderly patients who get admitted with a good WFNS score (I-III) seem to benefit from aggressive treatment whereas caution seems to be warranted particularly in patients ≥ 70 years of age who get admitted in a WFNS score of IV and V because of their limited short- and long-term prognosis.

    Aim of the study The aim of this retrospective chart review was to determine the long-term outcomes and identify prognostic factors that impact the survival of patients with cervical cancer. Material and methods A retrospective chart review of 739 patients with International Federation of Gynaecology and Obstetrics (FIGO) stage I–IV cervical cancer treated with surgery, radiation or chemoradiation was performed. Patient charts were evaluated in terms of demographics, clinical outcomes, and survival. Disease-free survival (DFS) and overall survival (OS) were calculated with the Kaplan-Meier method, and differences in survival were compared with the log-rank test. Multivariate analysis was performed with a Cox proportional hazards model to determine the estimated hazard ratios (HR) with 95% confidence intervals (CI) for each prognostic factor. Results The Cox proportional hazards model demonstrated that pelvic nodal metastasis (p = 0.018), parametrial invasion (p = 0.015), and presence of disease in the surgical margin (p = 0.011) were all independent prognostic factors for OS. The 5-year OS rate of patients with negative pelvic lymph nodes was 67.1%, which was higher than the rate for those with positive nodes at 49.0% (p < 0.05). The 5-year OS rate was 54.3% for patients with metastasis to the parametrium, 79.2% with a cancer-free parametrium, 60.9% with a cancer-positive surgical margin, 85.4% with a cancer-negative surgical margin, and 64.3% with a 1–3 mm close surgical margin (p < 0.05). Conclusions Assessing pelvic lymph nodes, the parametrium, and surgical margins is important for survival and may aid in better identifying patients who would derive greater benefits from receiving adjuvant therapies and more aggressive treatments.

    Purpose: To study the outcomes of patients with adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix primarily treated with radiotherapy (RT), identify the prognostic factors, and evaluate the efficacy of concurrent chemoradiotherapy (CCRT) or salvage surgery. Methods and Materials: A total of 148 patients with Stage I-IVA AC/ASC of cervix after full-course definitive RT were included. Of the 148 patients, 77% had advanced stage disease. Treatment failure was categorized as either distant or local failure. Local failure was further separated into persistent tumor or local relapse after complete remission. The effectiveness of CCRT with cisplatin and/or paclitaxel was examined, and the surgical salvage rate for local failure was reviewed. Results: The 5-year relapse-free survival rate was 68%, 38%, 49%, 30%, and 0% for those with Stage IB/IIA nonbulky, IB/IIA bulky, IIB, III, and IVA disease, respectively, and appeared inferior to that of those with squamous cell carcinoma of the cervix treated using the same RT protocol. Incomplete tumor regression after RT, a low hemoglobin level, and positive lymph node metastasis were independent poor prognostic factors for relapse-free survival. CCRT with weekly cisplatinum did not improve the outcome for our AC/ASC patients. Salvage surgery rescued 30% of patients with persistent disease. Conclusion: Patients with AC/ASC of the cervix primarily treated with RT had inferior outcomes compared to those with squamous cell carcinoma. Incomplete tumor regression after RT was the most important prognostic factor for local failure. Salvage surgery for patients with persistent tumor should be encouraged for selected patients. Our results did not demonstrate a benefit of CCRT with cisplatin for this disease.

    To determine useful prognostic factors in treating childhood acute lymphoblastic leukemia (ALL), we correlated conventional risk factors and bone marrow response 14 days after induction chemotherapy. Our study included 116 precursor B-cell (n = 104) and T-cell (n = 12) ALL patients treated with our protocol between 1988 and 1999. The patients were classified into 3 initial risk groups on the basis of conventional risk factors (56 in the low-risk, 33 in the high-risk, and 27 in the very high-risk groups). All patients received similar systemic chemotherapy regimens before the evaluation of their bone marrow on day 14. We evaluated the marrow of 69 patients as M1 (less than 5% blasts), 25 as M2 (5%-25% blasts), and 22 as M3 (more than 25% blasts). Although all patients attained an initial complete remission (CR), relapse was noted in 33 of the 116 patients, and 15 patients died. All of the M1 marrow patients, irrespective of the initial risk group, showed the best event-free survival rate (85.1% +/- 3 4.4%), the lowest relapse rate (14.5%), and the highest attainment of a second CR (100%); they were defined as the new R1 prognostic group. The low-risk patients with M2 or M3 marrow (R2 group) had a relatively high relapse rate, but all of these relapsed patients were treated successfully with subsequent therapy. High- or very high-risk patients with M2 or M3 marrow (R3 group) had the worst prognosis. Our new prognostic definition (R1, R2, R3) incorporating day 14 marrow findings is useful to tailor early-phase treatments for better therapeutic results in childhood ALL.

    Objectives It was recently demonstrated that adverse cardiovascular events (ACVE) complicate a high proportion of hospitalizations for patients with acute drug overdoses. The aim of this study was to derive independent clinical risk factors for ACVE in patients with acute drug overdoses. Methods This prospective cohort study was conducted over 3 years at two urban university hospitals. Patients were adults with acute drug overdoses enrolled from the ED. In-hospital ACVE was defined as any of myocardial injury, shock, ventricular dysrhythmia, or cardiac arrest. Results There were 1,562 patients meeting inclusion/exclusion criteria (mean age, 41.8 years; female, 46%; suicidal, 38%). ACVE occurred in 82 (5.7%) patients (myocardial injury, 61; shock, 37; dysrhythmia, 23; cardiac arrests, 22) and there were 18 (1.2%) deaths. On univariate analysis, ACVE risk increased with age, lower serum bicarbonate, prolonged QTc interval, prior cardiac disease, and altered mental status. In a multivariable model adjusting for these factors as well as patient sex and hospital site, independent predictors were: QTc > 500 msec (3.8% prevalence, odds ratio [OR] 27.6), bicarbonate < 20 mEql/L (5.4% prevalence, OR 4.4), and prior cardiac disease (7.1% prevalence, OR 9.5). The derived prediction rule had 51.6% sensitivity, 93.7% specificity, and 97.1% negative predictive value; while presence of two or more risk factors had 90.9% positive predictive value. Conclusions The authors derived independent clinical risk factors for ACVE in patients with acute drug overdose, which should be validated in future studies as a prediction rule in distinct patient populations and clinical settings.

    Objective To determine which risk factors and subtypes of lower gastrointestinal bleeding (LGIB) are associated with adverse outcomes after hospital discharge (30-day readmissions, recurrent LGIB, and death). Patients and Methods We conducted a prospective observational study of consecutive patients admitted with LGIB to Beth Israel Deaconess Medical Center from April 1, 2013, through March 30, 2014. Patients were contacted 30 days after discharge to determine hospital readmissions, recurrent LGIB, and death. Multivariable Cox proportional hazards regression models were used to describe associations of variables with 30-day readmissions or recurrent LGIB. Logistic regression was used to determine association with mortality. Results There were 277 patients hospitalized with LGIB. Of the 271 patients surviving to discharge, 21% (n=57) were readmitted within 30 days, 21 of whom were admitted for recurrent LGIB. The following factors were associated with 30-day readmissions: developing in-hospital LGIB (hazard ratio [HR], 2.26; 95% CI, 1.08–4.28), anticoagulation (HR, 1.82; 95% CI, 1.05–3.10), and active malignancy (HR, 2.33; 95% CI, 1.11–4.42). Patients discharged while taking anticoagulants had higher rates of recurrent bleeding (HR, 2.93; 95% CI, 1.15–6.95). Patients with higher Charlson Comorbidity Index scores (odds ratio [OR], 1.57; 95% CI, 1.25–2.08), active malignancy (OR, 6.57; 95% CI, 1.28–28.7), and in-hospital LGIB (OR, 11.5; 95% CI, 2.56–52.0) had increased 30-day mortality risk. Conclusion In-hospital LGIB, anticoagulation, and active malignancy are risk factors for 30-day readmissions in patients hospitalized with LGIB. In-hospital LGIB, Charlson Comorbidity Index scores, and active malignancy are risk factors for 30-day mortality. PMID:26141075

    We investigated factors affecting the timing of signal detection by comparing variations in reporting time of known and unknown ADRs after initial drug release in the USA. Data on adverse event reactions (AERs) submitted to U.S. FDA was used. Six ADRs associated with 6 drugs (rosuvastatin, aripiprazole, teriparatide, telithromycin, exenatide, varenicline) were investigated: Changes in the proportional reporting ratio, reporting odds ratio, and information component as indexes of signal detection were followed every 3 months after each drugs release, and the time for detection of signals was investigated. The time for the detection of signal to be detected after drug release in the USA was 2-10 months for known ADRs and 19-44 months for unknown ones. The median lag time for known and unknown ADRs was 99.0-122.5 days and 185.5-306.0 days, respectively. When the FDA released advisory information on rare but potentially serious health risks of an unknown ADR, the time lag to report from the onset of ADRs to the FDA was shorter. This study suggested that one factor affecting signal detection time is whether an ADR was known or unknown at release. PMID:26641634

    T/natural killer-cell lymphoma (T/NKCL) is a heterogeneous group of lymphoma and has a higher incidence in Asia than in Western countries. T/NKCL is presented with various clinicopathologic features, and in general, associated with a poor clinical outcome. This study aims to analyze the clinical prognostic factors in patients with T/NKCL. From January 1999 to December 2009, a total of 170 patients with T/NKCL, except mycosis fungoides, were included in this retrospective study. The diagnosis was established according to World Health Organization classification. The clinical characteristics and prognostic factors were evaluated. Of the 170 patients, mainly peripheral T-cell lymphoma-unspecified (65 cases), precursor T-lymphoblastic lymphoma/leukemia (31 cases) and nasal NK/T-cell lymphoma (NKTCL, 19 cases), advanced disease (Ann Arbor stages III-IV) was presented in 68.8% and extranodal involvement was in 71.2% of the patients. According to the international prognostic index (IPI), 77 cases were categorized as high/intermediate or high-risk group. Using the prognostic index for peripheral T-cell lymphoma-unspecified (PIT), 87 cases were classified as group 3 or 4. Most of the initial regimens were CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone)-based chemotherapy (87.6%). Cumulative probability of overall survival at 5 years was 43%, and the median survival time was 44.5 months. Univariate analysis revealed that factors associated with a poor outcome were poor performance status (ECOG > 1) (P = 0.001), advanced disease (P = 0.009), the presence of B symptom (P = 0.001), multiple extranodal involvement (P = 0.005), bone marrow involvement (P = 0.003), elevated lactic dehydrogenase level (P = 0.019), IPI (P < 0.001), PIT (P < 0.001), abnormal white blood cell count (P = 0.016), decreased platelet count (P = 0.005) and serum Epstein-Barr virus (EBV) IgA positivity (P = 0.016). In the multivariate analysis, PIT (P < 0.001; relative risk, 3.221; 95% CI

    Objective To investigate association between genetic polymorphisms of GST, CYP and renal outcome or occurrence of adverse drug reactions (ADRs) in lupus nephritis (LN) treated with cyclophosphamide (CYC). CYC, as a pro-drug, requires bioactivation through multiple hepatic cytochrome P450s and glutathione S transferases (GST). Methods We carried out a multicentric retrospective study including 70 patients with proliferative LN treated with CYC. Patients were genotyped for polymorphisms of the CYP2B6, CYP2C19, GSTP1, GSTM1 and GSTT1 genes. Complete remission (CR) was defined as proteinuria ≤0.33g/day and serum creatinine ≤124 µmol/l. Partial remission (PR) was defined as proteinuria ≤1.5g/day with a 50% decrease of the baseline proteinuria value and serum creatinine no greater than 25% above baseline. Results Most patients were women (84%) and 77% were Caucasian. The mean age at LN diagnosis was 41 ± 10 years. The frequency of patients carrying the GST null genotype GSTT1-, GSTM1-, and the Ile→105Val GSTP1 genotype were respectively 38%, 60% and 44%. In multivariate analysis, the Ile→105Val GSTP1 genotype was an independent factor of poor renal outcome (achievement of CR or PR) (OR = 5.01 95% CI [1.02–24.51]) and the sole factor that influenced occurrence of ADRs was the GSTM1 null genotype (OR = 3.34 95% CI [1.064–10.58]). No association between polymorphisms of cytochrome P450s gene and efficacy or ADRs was observed. Conclusion This study suggests that GST polymorphisms highly impact renal outcome and occurrence of ADRs related to CYC in LN patients. PMID:27002825

    Background Tumor necrosis factor (TNF) superfamily ligands that provoke a dilated cardiac phenotype signal through a common scaffolding protein termed TNF receptor associated factor 2 (TRAF2); however, virtually nothing is known with regard to TRAF2 signaling in the adult mammalian heart. Methods and Results We generated multiple founder lines of mice with cardiac restricted overexpression of TRAF2 and characterized the phenotype of mice with higher expression levels of TRAF2 (MHC-TRAF2HC). MHC-TRAF2HC transgenic mice developed a time-dependent increase in cardiac hypertrophy, LV dilation and adverse LV remodeling, and a significant decrease in LV +dP/dt and −dP/dt when compared to littermate (LM) controls (p < 0.05 compared to LM). During the early phases of LV remodeling there was a significant increase in total matrix metalloproteinase (MMP) activity that corresponded with a decrease in total myocardial fibrillar collagen content. As the MHC-TRAF2HC mice aged, there was a significant decrease in total MMP activity accompanied by an increase in total fibrillar collagen content and an increase in myocardial tissue inhibitor of metalloproteinase-1 levels. There was a significant increase in NF-κB activation at 4 – 12 weeks and JNK activation at 4 weeks in the MHCs TRAF2HC mice. Transciptional profiling revealed that > 95% of the hypertrophic/dilated cardiomyopathy-related genes that were significantly upregulated genes in the MHC-TRAF2HC hearts contained κB elements in their promoters. Conclusions These results show for the first time that targeted overexpression of TRAF2 is sufficient to mediate adverse cardiac remodeling in the heart. PMID:23493088

    The Authors report on a series of 120 cases of endometrial carcinoma observed from 1980 to 1989, in the 1st Gynecological Oncology of the Oncological Hospital "M. Ascoli", Palermo. After careful clinical and pathologic review, the cases, subdivided in pre and post-menopausal groups, in order to verify possible differences between the two groups, were evaluated with reference to the principal risk factors and to some prognostic factors. As for the risk factors (old age, nulliparity, obesity, long fertile life, etc.), the data do not differ from the results in the literature. The evaluation of the prognostic indicators confirms once again the close relationship between histologic grade and myometrial invasion of the tumor. They have an important predictive value for prognosis and their knowledge is indispensable for an adequate therapeutic strategy, especially at pathologic stage I. Furthermore, findings show some delay in endometrial cancer diagnosis in the population studied, particularly in premenopausal women. Such delay turns out to be significantly associated with a greater myometrial infiltration of tumor.

    Background To investigate whether gross tumor volume (GTV) defined on radiotherapy planning scans a prognostic factor for esophageal squamous cell carcinoma (ESCC) patients treated with definitive radiotherapy. Methods From 2008 to 2011, 187 ESCC patients who were treated with definitive radio(chemo)therapy were analyzed retrospectively. Tumor volumes such as GTV, gross tumor volume of primary esophageal cancer (GTV-P), and gross tumor volume of metastases lymph nodes (GTV-N) were computed by Philips Healthcare radiation therapy planning system (Pinnacle 8.0). Kaplan-Meier cumulative probability and Cox proportional hazards regression models were used to assess the effect of the clinical factors along with tumor volume on progression-free survival (PFS) and overall survival (OS). Results In the univariate analysis, fraction dose, TNM stage, total radiation dose, GTV, GTV-P, and GTV-N were all significantly associated with both OS and PFS (P<0.05). While in multivariate analysis, GTV and fraction dose were significantly associated with both OS and PFS (adjusted P<0.05) with adjustment for age, sex, smoking status, chemotherapy, fraction dose, GTV, and radiation dose. Conclusions GTV may serve as a good prognostic factor for ESCC patients treated with definitive radiotherapy. Larger prospective studies are needed to validate these findings. PMID:27293832

    Background Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. Objective To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Maceió. Methods Prospective cohort study carried out in 2014 in the public health network of the city with a sample of pregnant women calculated based on a prevalence of preeclampsia of 17%, confidence level of 90%, power of 80%, and ratio of 1:1. We applied a questionnaire to collect socioeconomic, personal, and anthropometric data, and retrieved perinatal variables from medical records and certificates of live birth. The analysis was performed with Poisson regression and chi-square test considering p values < 0.05 as significant. Results We evaluated 90 pregnant women with preeclampsia (PWP) and 90 pregnant women without preeclampsia (PWoP). A previous history of preeclampsia (prevalence ratio [PR] = 1.57, 95% confidence interval [95% CI] 1.47 - 1.67, p = 0.000) and black skin color (PR = 1.15, 95% CI 1.00 - 1.33, p = 0.040) were associated with the occurrence of preeclampsia. Among the newborns of PWP and PWoP, respectively, 12.5% and 13.1% (p = 0.907) were small for gestational age and 25.0% and 23.2% (p = 0.994) were large for gestational age. There was a predominance of cesarean delivery. Conclusion Personal history of preeclampsia and black skin color were associated with the occurrence of preeclampsia. There was a high frequency of birth weight deviations and cesarean deliveries. PMID:26761076

    Purpose To evaluate the association between spontaneous reporting (SR) and the knowledge, attitude, and needs of community pharmacists (CPs), using a questionnaire following a conceptual model known as the mixed model of knowledge-attitude-practices and the satisfaction of needs. Methods Self-administered questionnaires were used with a nationwide convenience sample of CPs between September 1, 2014 and November 25, 2014 in Korea. The association between SR and the predictive factors was evaluated using multivariate logistic regression analysis. Results In total, 1,001 questionnaires were analyzed. The mean age of the respondents and the number of years spent in community pharmacy practice were 45.6 years and 15.3 years, respectively. CPs with experience of SR was 29.4%. Being older than 60 (ORadj, 0.16; 95% CI, 0.06–0.42), having prior experience with adverse drug reactions (ADR) (ORadj, 6.46; 95% CI, 2.46–16.98), having higher specific knowledge of SR (ORadj, 3.58; 95% CI, 1.96–6.56), and having less concern about the obstacles to SR (ORadj, 0.36; 95% CI, 0.23–0.57) were significant contributing factors to SR. The main obstacles to SR included perception of ADRs as ‘not serious ADR’ (77.9%), ‘already well known ADR’ (81.5%), and ‘uncertain about causality’ (73.3%). CPs without reporting experience had greater concerns related to the reporting method and the liability of the pharmacy than those with reporting experience (p<0.05). Conclusions Findings from our study showed around one in three CPs had ADR reporting experience in Korea, while 87.1% had prior experience with ADR cases. The knowledge of SR, prior experience of ADR, and less concern about the obstacles to SR were contributing factors for reporting levels. PMID:27192159

    BRCA1 promoter methylation is an essential epigenetic transcriptional silencing mechanism, related to breast cancer (BC) occurrence and progression. We quantified the methylation level of BRCA1 promoter and evaluated its significance as prognostic and predictive factor. BRCA1 promoter methylation level was quantified by pyrosequencing in surgical cancerous and adjacent normal specimens from 154 BC patients. A follow up of 98 months was conducted to assess the correlation between BRCA1-methylation level vs. overall survival (OS) and disease free survival (DFS). The mean methylation level in BC tissues was significantly higher (mean 32.6%; median 31.9%) than in adjacent normal samples (mean 16.2%; median 13.0%) (P < 0.0001). Tumor stage (R = 0.6165, P < 0.0001) and size (R = 0.7328, P < 0.0001) were significantly correlated with the methylation level. Patients with unmethylated BRCA1 had a better OS and DFS compared to the methylated group (each P < 0.0001). BRCA1 promoter methylation level has a statistically significance on survival in BC patients (HazR = 1.465, P = 0.000) and is an independent prognostic factor for OS in BC patients (HazR = 2.042, P = 0.000). Patients with ductal type, HER2 negative, lymph node negative stage 1+2 tumors had a better OS and DFS. Classification of grades and molecular subtypes did not show any prognostic significance. Pyrosequencing is a precise and efficient method to quantify BRCA1 promoter methylation level, with a high potential for future clinical implication, as it identifies subgroups of patients with poorer prognosis.

    The lysosome-associated protein transmembrane-4β-35 (LAPTM4B-35) protein has been indicated to be involved in solid tumors, while its role in small cell lung cancer (SCLC) remains unknown. The aim of this study is to investigate the LAPTM4B-35 protein expression and its clinical and prognostic role in SCLC patients. A total of 88 SCLC patients who underwent radical surgery between 2002 and 2010 were enrolled in the study. The level of messenger RNA (mRNA) and protein was detected from the fresh paired tumor specimens and adjacent normal tissues. The clinicopathological and survival data were collected. And the relationship between LAPTM4B-35 and clinicopathological features was analyzed. The prognostic value of LAPTM4B-35 for SCLC was investigated by univariate and multivariate analyses. The LAPTM4B-35 was overexpressed significantly in SCLC cancer tissues. The elevated protein expression was correlated strongly with clinical stage (p = 0.012) and tumor recurrence (p = 0.023). The 5-year overall survival and disease-free survival (DFS) were significantly worse in the patients with high LAPTM4B-35 level. Multivariate Cox analysis indicated that high LAPTM4B-35 expression was an independent prognostic factor for overall survival (OS) and DFS (p = 0.017 vs p = 0.011). LAPTM4B-35 overexpression was an independent factor in SCLC prognosis, which may be considered a potential useful marker in defining the SCLC prognosis.

    To summarise evidence on therapeutic interventions and prognostic factors in polymyalgia rheumatica (PMR). A systematic literature review was conducted using Ovid Medline, Embase, PubMed, CINAHL, Web of Science and the Cochrane Library (1970 through April 2014). Quality of evidence (QoE) of identified studies was appraised by Grading of Recommendations Assessment, Development and Evaluation (GRADE) (interventions) and the Quality In Prognosis Studies (QUIPS) methodologies (prognostic factors). Out of 10 931 titles identified, 52 articles were finally selected. A single study indicated that an initial prednisone dose of 20 mg/day is associated with a lower short-term relapse rate than 10 mg/day but at the cost of a higher rate of adverse events. Another study suggested a comparable efficacy of intramuscular methylprednisolone and oral glucocorticoids (GCs) with lower cumulative GC doses and less weight gain in the former group. Moderate to high QoE (1-2 studies) indicated a benefit of methotrexate in remission rates and cumulative GC doses in early PMR. Anti-tumour necrosis factor α agents are ineffective for PMR treatment. Among prognostic factors, female sex, high erythrocyte sedimentation rate (ESR) and peripheral arthritis were associated in some studies with a higher relapse risk. Women and patients with high ESR also appeared to have a longer duration of treatment. Several studies of varying quality, however, failed to prove these associations. In PMR, evidence for initial GC doses and subsequent tapering regimens is limited. Intramuscular methylprednisolone and methotrexate may be effective GC sparing agents. Female sex, high ESR and peripheral arthritis at disease outset are potential risk factors for a worse prognosis. PMID:26359489

    Progress in cancer biology has led to an increasing discovery of oncogenic alterations of the platelet-derived growth factor receptors (PDGFRs) in cancers. In addition, their overexpression in numerous cancers invariably makes PDGFRs and platelet-derived growth factors (PDGFs) prognostic and treatment markers in some cancers. The oncologic alterations of the PDGFR/PDGF system affect the extracellular, transmembrane and tyrosine kinase domains as well as the juxtamembrane segment of the receptor. The receptor is also involved in fusions with intracellular proteins and receptor tyrosine kinase. These discoveries undoubtedly make the system an attractive oncologic therapeutic target. This review covers elementary biology of PDGFR/PDGF system and its role as a prognostic and treatment marker in cancers. In addition, the multifarious therapeutic targets of PDGFR/PDGF system are discussed. Great potential exists in the role of PDGFR/PDGF system as a prognostic and treatment marker and for further exploration of its multifarious therapeutic targets in safe and efficacious management of cancer treatments.

    Estracyt○R (estramustine phosphate) is a medical drug for prostate cancer with cytotoxic activity causing disruption of microtubule organization and indirect androgen production suppressing activity by its metabolite, estradiol. Based on the data obtained from the Estracyt○R Special Drug Use Investigation which surveyed the clinical efficacy and safety of Estracyt○R in patients with prostate cancer whose relapse of prostate cancer after combined androgen blockade (CAB) therapy was confirmed, we evaluated the progression-free survival, prognostic factor, decrease in prostate specific antigen (PSA) level and safety. This surveillance was conducted at 147 institutions nationwide between October, 2010 and September, 2013 and clinical efficacy was evaluated in 239 cases and safety in 329 cases. The median duration of progression-free survival, PSA progression-free survival and PSA response were 169 days (95%CI, 142-190), 197 days (95%CI, 169-267) and 385 days, respectively. The decrease in PSA level was observed in 125 cases (52.3%). Rate of PSA decline >50 and >25% were 18.4 and 43.1, respectively, and rate of PSA best response (PSA decline > 50%) was 32.6%. Multivariate analysis demonstrated that long duration of prior CAB therapy, Estracyt○R - pretreatment PSA value and bone metastasis influenced progression-free survival significantly. Adverse events were observed in 127 cases (38.6%). The major adverse events were anorexia which was observed in 35 cases (10.9%), gastrointestinal disorders observed in 32 cases (9.7%), abnormal laboratory test values observed in 31 cases (9.4%) and gynecomastia observed in 16 cases (4.9%). These results suggest the clinical efficacy and safety of Estracyt○R for chemotherapy-naïve castration-resistant prostate cancer (CRPC), and Estracyt○R is regarded as one of the treatment options for patients with CRPC, especially for patients who had long duration of prior CAB therapy.

    Causal factors in aviation accidents and incidents related to system/component failure/malfunction (SCFM) were examined for Federal Aviation Regulation Parts 121 and 135 operations to establish future requirements for the NASA Aviation Safety Program s Integrated Vehicle Health Management (IVHM) Project. Data analyzed includes National Transportation Safety Board (NSTB) accident data (1988 to 2003), Federal Aviation Administration (FAA) incident data (1988 to 2003), and Aviation Safety Reporting System (ASRS) incident data (1993 to 2008). Failure modes and effects analyses were examined to identify possible modes of SCFM. A table of potential adverse conditions was developed to help evaluate IVHM research technologies. Tables present details of specific SCFM for the incidents and accidents. Of the 370 NTSB accidents affected by SCFM, 48 percent involved the engine or fuel system, and 31 percent involved landing gear or hydraulic failure and malfunctions. A total of 35 percent of all SCFM accidents were caused by improper maintenance. Of the 7732 FAA database incidents affected by SCFM, 33 percent involved landing gear or hydraulics, and 33 percent involved the engine and fuel system. The most frequent SCFM found in ASRS were turbine engine, pressurization system, hydraulic main system, flight management system/flight management computer, and engine. Because the IVHM Project does not address maintenance issues, and landing gear and hydraulic systems accidents are usually not fatal, the focus of research should be those SCFMs that occur in the engine/fuel and flight control/structures systems as well as power systems.

    Kidney transplantation is the optimal treatment of ESRD in children. Some studies have reported inferior outcomes in recipients of LDN allografts who are ≤ 5 yr of age. We performed a retrospective review of pediatric recipient outcomes of 110 LDN allografts at our institution and examined predictors of adverse outcomes. Subgroup analysis was performed by dividing recipients into three age categories: 0-5 yr, 6-17 yr, and ≥ 18 yr. There was no significant difference between incidences of DGF or ARE between groups. Kaplan-Meier analysis demonstrated 100% allograft survival in 0- to 5-yr-old recipients, nearly reaching statistical significance (p = 0.07) for outcome superior to that of the two older age groups. Pretransplant HD was associated with increased risk of DGF (p = 0.05). Significant risk factors for ARE were recipient weight >15 kg (p = 0.033) and multiple renal arteries (p = 0.047). Previous ARE was associated with an increased risk of allograft failure (p = 0.02). LDN is not associated with increased risk of DGF, ARE, or allograft failure in the youngest recipients. These findings support an aggressive pursuit of preemptive transplantation even in the youngest pediatric allograft recipients. PMID:26329665

    The prevalence of adverse childhood experiences (ACEs) among Hawai‘i adults and their impact on the health of affected individuals are unknown. Aiming to provide Hawai‘i State baseline information on ACEs and their associations with health conditions and risk behaviors, the 2010 Hawai‘i Behavioral Risk Factor Surveillance System (BRFSS) included the ACE module. Using 5,928 survey respondents who completed the module, demographic attributes were estimated and multivariate logistic regression analysis was performed to examine the association between ACEs and sixteen selected health indicators. In 2010, approximately 57.8% of Hawai‘i adults reported experiencing at least one ACE. Native Hawaiians had the highest prevalence followed by Whites. Adults aged ≥ 65 years had the lowest prevalence on all ACEs. The prevalence of ACEs was inversely related to education and household income levels. Compared to those without ACEs, adults with ACEs had higher odds for a number of health conditions and risk behaviors. Moreover, as the number of ACEs increased, the odds for these health conditions and risk behaviors increased. Hawai‘i adults with ACEs were more likely to report dissatisfaction with life compared to those without ACEs. Men were more likely to report having a family member in prison, while women were more likely to report experiencing sexual abuse. Recommendations include further research on the unbiased contributions of ACEs to diseases and risk behaviors, and the development of culturally-appropriate interventions to reduce the prevalence of ACEs in Hawai‘i.

    Objective According to the basic role of drug side effects in selection of an appropriate drug, patient compliance and the quality of life in epileptic patients, and forasmuch as new drugs with unknown side effect have been introduced, necessity of this research is explained. This study was conducted to evaluate the incidence and clinical characteristics of anti epileptic drug (AED) related adverse reactions in children. Material & Methods In this descriptive study, children less than 14 years old with AED side effects referred to the Children’s Medical Center and Mofid Childeren’s Hospital (Tehran, Iran) were evaluated during 2010-2012. The informations were: sex, age, incriminating drug, type of drug side effect, incubation period, history of drug usage, and patient and family allergy history. Exclusive criterions were age more than 14 years old and reactions due to reasons other than AEDs. Results A total of 70 patients with AED reaction were enrolled in this study. They included 26 (37%) females and 44 (63%) males. The maximum rate of incidence was seen at age less than 5 years old. All the patients had cutaneous eruptions that the most common cutaneous drug eruption was maculopapular rash. The most common culprit was phenobarbital (70%) and the least common was lamotrigine (1.4%). Conclusion In this study, we found higher rates of drug rash in patients treated with aromatic AEDs and lower rates with non-aromatic AEDs. Various endogenous and environmental factors may influence the propensity to develop these reactions. PMID:24665302

    Purpose: To investigate the prognostic value of epidermal growth factor receptor (EGFR) expression in pretreatment tumor biopsy specimens of patients with anal cancer treated with concurrent 5-fluorouracil and mitomycin C-based chemoradiation therapy (CRT). Methods and Materials: Immunohistochemical staining for EGFR was performed in pretreatment biopsy specimens of 103 patients with anal carcinoma. EGFR expression was correlated with clinical and histopathologic characteristics and with clinical endpoints, including local failure-free survival (LFFS), colostomy-free survival (CFS), distant metastases-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Results: EGFR staining intensity was absent in 3%, weak in 23%, intermediate in 36% and intense in 38% of the patients. In univariate analysis, the level of EGFR staining was significantly correlated with CSS (absent/weak vs intermediate/intense expression: 5-year CSS, 70% vs 86%, P=.03). As a trend, this was also observed for DMFS (70% vs 86%, P=.06) and LFFS (70% vs 87%, P=.16). In multivariate analysis, N stage, tumor differentiation, and patients’ sex were independent prognostic factors for CSS, whereas EGFR expression only reached borderline significance (hazard ratio 2.75; P=.08). Conclusion: Our results suggest that elevated levels of pretreatment EGFR expression could be correlated with favorable clinical outcome in anal cancer patients treated with CRT. Further studies are warranted to elucidate how EGFR is involved in the response to CRT.

    Purpose A limited number of studies have examined the link between F-wave abnormalities and clinical presentation in pediatric Guillain-Barré syndrome (GBS). Therefore, this study examined the importance of F-wave abnormalities as a prognostic factor in pediatric GBS patients. Methods The records and electrodiagnostic studies (EDS) of 70 GBS patients were retrospectively evaluated, and divided into 2 groups according to the results of EDS. Group A (n=33) presented with F-wave abnormalities, and group B (n=26) exhibited normal findings. We compared laboratory reports, clinical features, response to treatment, and prognosis between the 2 groups. Results Motor weakness was the most frequently observed symptom for either group. Clinically, the incidence of fever and upper respiratory symptoms differed between the 2 groups, while the prevalence of abnormal deep tendon reflex (DTR) was significantly higher in group A than B (P<0.05). Patients diagnosed with GBS had received intravenous immunoglobulin treatment: 94% in group A and 58% in group B. Furthermore, significantly greater numbers of patients in group A showed H-reflex abnormalities and poor prognosis compared with group B (P<0.05). Conclusion This study demonstrated that F-waves are a clinically important prognostic factor in GBS. F-wave abnormalities were associated with abnormal DTR and poor prognosis in patients. Limited studies have examined the link between F-wave abnormalities and clinical results; therefore, further randomized controlled studies are needed to confirm the clinical characteristics and efficacy of treatments.

    Early identification of children at high risk of diarrhoea-associated dehydration would be of great value to health care workers in developing countries. To identify prognostic factors for life-threatening dehydration, we carried out a case-control study among under-2-year-olds in Porto Alegre, Brazil. Cases were 192 children admitted to hospital with moderate or severe dehydration, while controls were children matched to controls by neighbourhood and age, who experienced nondehydrating diarrhoea in the week preceding the interview. The following variables were significantly associated with an increased risk of dehydration, after adjustment for age and other confounding variables: absence of the father from the home; low paternal education level; young age; maternal age 25-29 years or less than 20 years; mother of mixed race; high birth order; short birth interval; low birth weight; stunting, underweight and wasting; lack of breast-feeding; presence of other under-5-year-olds in the home; families with 4-5 members; lack of antenatal care; less than three doses of diphtheria-pertussis-tetanus or poliomyelitis vaccine; previous admission to hospital; use of medicines during the fortnight prior to the episode; and living in an unclean home. The associations were particularly strong (P less than 0.001) for the child's age, birth weight and other anthropometric indicators, birth interval, and feeding mode. In terms of their sensitivity and specificity, however, these prognostic factors were not as effective as early signs and symptoms for predicting the outcome of the episode.

    Purpose The purpose of this study was to investigate the clinicopathologic features and prognostic factors affecting outcome in patients with isolated locoregional recurrence of breast cancer (ILRR). Methods We retrospectively analyzed the medical records of 104 patients who were diagnosed with ILRR and underwent curative surgery from January 2000 to December 2010 at Samsung Medical Center. Results Among 104 patients, 43 (41%) underwent total mastectomy and 61 (59%) underwent breast-conserving surgery for primary breast cancer. The median time from initial operation to ILRR was 35.7 months (4.5–132.3 months). After diagnosis of ILRR, 45 (43%) patients were treated with mastectomy, 41 (39%) with excision of recurred lesion, and 18 (17%) with node dissection. During a median follow-up of 8.9 years, the 5-year overall survival was 77% and 5-year distant metastasis-free survival (DMFS) was 54%. On multivariate analysis, younger age (< 35 years), higher stage, early onset of elapse (≤ 24 months), lymph node recurrences, and subtype of triple negative breast cancer (TNBC) were found to be independently associated with DMFS. Patients in the no chemotherapy group showed a longer DMFS after surgery for ILRR than those treated with chemotherapy (median 101.5 vs. 48.0 months, p = 0.072) but without statistical significance. Conclusion Our analysis showed that younger age (< 35 years), higher stage, early onset of relapse (≤ 24 months), lymph node recurrence, and subtype of TNBC are the worst prognostic factors for ILRR.

    Long non-coding RNAs (lncRNAs) have been suggested to serve as an important role in tumor development and progression. The aim of this study was to analyse the association between lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and cancer patients' overall survival. We systematically and carefully searched the studies from electronic databases and seriously identified according to eligibility criteria. The correlation between lncRNA MALAT1 expression and overall survival in human cancers was evaluated through Review Manager. A total of 8 studies which included 792 cancer patients were included in the final analysis. Meta-analysis showed that lncRNA MALAT1 overexpression was correlated with a poor overall survival and the pooled hazard ratio (HR) and corresponding 95% confidence interval (CI) was 1.94 (95% CI 1.59-2.38). From subgroup analyses, we present evidence that lncRNA MALAT1 overexpression was an unfavorable prognostic factor for patients' overall survival in non-small cell lung cancer and pancreatic cancer, the pooled HRs (95% CI) were 1.86 (95% CI 1.27-2.73) and 1.78 (95% CI 1.30-2.44), respectively. In conclusion, lncRNA MALAT1 is a potential prognostic factor in human cancers.

    Purpose: To identify prognostic factors for pathologic N2 (pN2) non-small cell lung cancer (NSCLC) treated by surgical resection. Methods: Between 1990 and 2009, 287 patients with pN2 NSCLC underwent curative resection at the Cancer Institute Hospital without preoperative treatment. Results: The 5-year overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) rates were 46%, 55% and 24%, respectively. The median follow-up time was 80 months. Multivariate analysis identified four independent predictors for poor OS: multiple-zone mediastinal lymph node metastasis (hazard ratio [HR], 1.616; p = 0.003); ipsilateral intrapulmonary metastasis (HR, 1.042; p = 0.002); tumor size >30 mm (HR, 1.013; p = 0.002); and clinical stage N1 or N2 (HR, 1.051; p = 0.030). Multivariate analysis identified three independent predictors for poor RFS: multiple-zone mediastinal lymph node metastasis (HR, 1.457; p = 0.011); ipsilateral intrapulmonary metastasis (HR, 1.040; p = 0.002); and tumor size >30 mm (HR, 1.008; p = 0.032). Conclusion: Multiple-zone mediastinal lymph node metastasis, ipsilateral intrapulmonary metastasis, and tumor size >30 mm were common independent prognostic factors of OS, CSS, and RFS in pN2 NSCLC.

    Background Gastric and esophageal adenocarcinomas are major global cancer burdens. These cancer forms are characterized by a poor prognosis and a modest response to chemo- radio- and targeted treatment. Hence there is an obvious need for further enhanced diagnostic and treatment strategies. The aim of this study was to examine the expression and prognostic impact of human epidermal growth factor receptor 1 (HER1/EGFR) and 3 (HER3), as well as the occurrence of EGFR and KRAS mutations in gastric and esophageal adenocarcinoma. Methods Immunohistochemical expression of EGFR and HER3 was analysed in all primary tumours and a subset of lymph node metastases in a consecutive cohort of 174 patients with adenocarcinoma of the stomach, cardia and esophagus. The anti-HER3 antibody used was validated by siRNA-mediated knockdown, immunohistochemistry and quantitative real-time PCR. EGFR and KRAS mutation status was analysed by pyrosequencing tecchnology. Results and Discussion High EGFR expression was an independent risk factor for shorter overall survival (OS), whereas high HER3 expression was associated with a borderline significant trend towards a longer OS. KRAS mutations were present in only 4% of the tumours and had no prognostic impact. All tumours were EGFR wild-type. These findings contribute to the ongoing efforts to decide on the potential clinical value of different HERs and druggable mutations in gastric and esophageal adenocarcinomas, and attention is drawn to the need for more standardised investigational methods.

    AIMS: To evaluate correlations among clinical, pathological, morphometric, stereological, and DNA flow cytometric variables and their prognostic value in advanced ovarian cancer. METHODS: Tissue was collected from 180 patients with advanced ovarian cancer. All 180 had undergone debulking surgery and were being treated with cisplatin. Long term follow up was available for all patients. The mitotic activity index (MAI), volume % of epithelium (VPE), mean nuclear area (MNA), standard deviation of the nuclear area (SDNA), estimates of volume weighted mean nuclear volume (nu v), and variables obtained from minimum spanning tree (MST) analysis were assessed in the least differentiated tumour section in each case. DNA flow cytometry was also performed. RESULTS: Quantitative pathological features differed significantly with respect to histological grade. The MAI, MNA, SDNA, and the number of points connected to three neighbours differed significantly among the different DNA ploidy groups. The VPE and number of points connected to two or three neighbours differed significantly between FIGO stages III and IV. Fifty two (29%) patients survived. FIGO stage, residual disease and SDNA had prognostic significance on both univariate and multivariate survival analysis. In patients with FIGO III stage disease and residual tumour nodes < or = 2 cm in diameter (67 patients, 29 (43%) survivors) a prognostic index was established based on SDNA and of the line length of the MST. The median survival time was not reached in a subgroup of patients with favourable prognosis (overall survival 57%). Median survival was 32 months for patients with an unfavourable index score (overall survival 28%). CONCLUSION: Morphometric variables have important additional value in predicting prognosis in patients with advanced ovarian cancer. PMID:8655681

    In end-stage heart failure, left ventricular assist devices (LVADs) represent an exciting new frontier in which post-device-implantation survival approaches that of heart transplant. However, expansion of this technology is still limited by complications that impact morbidity and mortality. Thus, it is essential to identify and optimize modifiable predictors of poor outcomes. One such predictor may be hypertension (HTN). Not only may chronic HTN as a traditional cardiovascular risk factor be present during long-term LVAD support, but HTN may also contribute to device malfunction or device-associated complications. Although current guidelines identify blood pressure (BP) control as important to outpatient continuous flow (CF) LVAD management, there is no evidence base to support these guidelines. Indeed, our comprehensive literature search did not identify any studies that evaluated post-device-implantation HTN as a potential predictor of adverse CF-LVAD outcomes. Hypertension among CF-LVAD patients is likely a relatively unstudied factor because of difficulties using standard non-invasive techniques to measure BP in the setting of reduced pulsatile flow. Fortunately, recent research has elucidated the meaning of Doppler BP measurements and validated a slow-deflation cuff system for BP measurements in the setting of CF-LVAD support. Therefore, CF-LVAD researchers and clinicians may i) consider potential mechanisms relating HTN to poor outcomes, ii) realize that HTN management is a stated goal despite scarce evidence, and iii) utilize the new reliable and valid methods for outpatient BP measurement that make research and management possible. It is critical and now feasible that research on HTN in the CF-LVAD patient population move forward. PMID:25283767

    Background Lung cancer is the leading cause of cancer deaths in the world, and more and more treatment modalities have been introduced in order to improve patients’ survival. For patients with advanced non-small cell lung cancer (NSCLC), survival prognosis is poor and multimodality neoadjuvant therapies are given to improve patients’ survival. However, the possibility of occult metastases may lead to discrepancy between clinical and pathologic staging and underestimation of the disease severity. This discrepancy could be the reason for poor survival prediction reported by previous studies which conducted their analysis from the point of view of clinical stage. The aim of this study was to analyze the relationship between clinico-pathologic factors and survival from the pathologic point of view and to try to identify survival prognostic factors. Methods From January 2005 to June 2011, 88 patients received neoadjuvant therapy because of initial locally advanced disease, followed by anatomic resection and mediastinal lymph node (LN) dissection. All their clinico-pathologic data were collected from a retrospective review of the medical records and subjected to further analysis. Results We found that total metastatic LN ratio (P=0.01) and tumor size (P=0.02) were predictive factors for disease free survival (DFS). We used these two prognostic factors to stratify all patients into four groups. Group 4 (tumor size ≤5, total metastatic LN ratio ≤0.065) had the best DFS curve, while the DFS curve progressively deteriorated across group 3 (tumor size ≤5, total metastatic LN ratio >0.065), group 2 (tumor size >5, total metastatic LN ratio ≤0.065) and group 1 (tumor size >5, total metastatic LN ratio >0.065). However, no definitive prognostic factor could be identified in this study. Conclusions In conclusion, tumor size greater than 5 cm and total metastatic LN ratio greater than 0.065 could predict the DFS of patients with advanced NSCLC after multimodality

    Data of clinical trial projects involved by clinical trial institutions certified by the State Food and Drug Administration from 2002 to November 2012 were collected to summarize adverse reactions in project summary/statistical reports, analyze the rate of adverse reactions of clinical trials of new traditional Chinese medicines and relevant influencing factors, and increase the awareness of the safety of new traditional Chinese medicines. A total of 73 050 cases in 209 projects of 14 specialties were collected, including 49 689 cases in the new traditional Chinese medicine group and 271 adverse reaction cases, with an incidence rate of adverse reactions at 0.55%. The adverse reaction rate in 3 months < middle long course ≤ 6 months was the highest (1.04%), whereas that in short course ≤ half a month was the lowest (0.48%). The adverse reaction was closely related with the route of administration, 1.28% for topical > 0.63% for injection > 0.50% for oral. In the administration of only the test drug, the adverse reaction rate of patches was the highest (2.68%), whereas that of aerosols and suppositories was lowest (0). In the combined administration of the test drug and the simulation agent, the adverse reaction rate of external test patch + capsule was the highest (3.38%), whereas that of capsule + oral liquid, pills + granules, tablets + oral liquid, tablets + pills, tablet + capsule was the lowest (0). In the administration of only the test drug, the adverse reaction rate was 0.47%; In the combined administration with simulation agent (drug volume increase), the adverse reaction rate was 0.74%. Different doses caused adverse reaction different rates; The adverse reaction rate of drugs with whole-course dose between 1 100-1 200 g was the highest (3.36%), that for whole-course doses of 500-600, 900-1 000, 1 400-1 500, 1 600-1 700, 1 800-1 900 g was the lowest (0).

    This retrospective study aimed at evaluating the long-term outcomes and prognostic factors of microwave ablation (MWA) as a first-line treatment for hepatocellular carcinoma (HCC). 221 consecutive patients receiving MWA in our center between October 11, 2010 and December 31, 2013 were enrolled. Technique effectiveness was evaluated one month post-ablation. Initial complete ablation (CA1(st)) was gained in 201 (90.95%) patients, secondary CA (CA2(nd)) in 8 (3.62%) patients and the remaining 12 (5.43%) patients suffered from incomplete ablation (IA2(nd)) after two sessions of MWA. Patients with tumor size >5 cm were less likely to gain CA1(st). Procedure-related complications were recorded and no procedure-related death occurred. 22 (10.4%) complications occurred with 8 (3.8%) being major ones. Tumor characteristics (size, number, location) do not significantly influence complication rates. After a median follow-up of 41.0 (ranging 25.0-63.5) months, the median RFS and OS was 14.0 months (95% CI: 9.254-18.746) and 41.0 months (95% CI: 33.741-48.259) respectively. Multivariate analysis identified two significant prognosticators (levels of alpha fetal protein [AFP] and gamma-glutamyl transpeptidase [GGT]) of RFS and five significant prognosticators (tumor number, tumor size, AFP, GGT and recurrence type) of OS. In conclusion, MWA provides high technique effectiveness rate and is well tolerated in patients with HCC as a first-line treatment. PMID:27620527

    This retrospective study aimed at evaluating the long-term outcomes and prognostic factors of microwave ablation (MWA) as a first-line treatment for hepatocellular carcinoma (HCC). 221 consecutive patients receiving MWA in our center between October 11, 2010 and December 31, 2013 were enrolled. Technique effectiveness was evaluated one month post-ablation. Initial complete ablation (CA1st) was gained in 201 (90.95%) patients, secondary CA (CA2nd) in 8 (3.62%) patients and the remaining 12 (5.43%) patients suffered from incomplete ablation (IA2nd) after two sessions of MWA. Patients with tumor size >5 cm were less likely to gain CA1st. Procedure-related complications were recorded and no procedure-related death occurred. 22 (10.4%) complications occurred with 8 (3.8%) being major ones. Tumor characteristics (size, number, location) do not significantly influence complication rates. After a median follow-up of 41.0 (ranging 25.0–63.5) months, the median RFS and OS was 14.0 months (95% CI: 9.254–18.746) and 41.0 months (95% CI: 33.741–48.259) respectively. Multivariate analysis identified two significant prognosticators (levels of alpha fetal protein [AFP] and gamma-glutamyl transpeptidase [GGT]) of RFS and five significant prognosticators (tumor number, tumor size, AFP, GGT and recurrence type) of OS. In conclusion, MWA provides high technique effectiveness rate and is well tolerated in patients with HCC as a first-line treatment. PMID:27620527

    Although eosinophilic granulocytes are frequently observed in lymphatic tissue of Hodgkin's patients, no substantial data reveal the prognostic role, if any, of tissue eosinophilia. Thus, eosinophilia was analyzed histologically in 1511 diagnostic biopsy specimens of patients treated under protocol therapy of the German Hodgkin's Lymphoma Study Group between 1988 and 1994. Prominent eosinophilia was seen in 38% of cases, which differed among the histologic types of Hodgkin's disease (HD): none in lymphocyte predominant, 14% in lymphocyte rich classical, 40% in nodular sclerosis grade 1 (NS-1), 55% in nodular sclerosis grade 2, 43% in mixed cellularity (MC), and 54% in lymphocyte depleted. In a multivariate analysis, tissue eosinophilia proved to be the strongest prognostic factor for freedom from treatment failure (P <. 001) and overall survival (P <.001) in a stage-stratified model. Among NS-1 patients, the effect was highly significant. In MC, no significant effect of eosinophilia on survival could be demonstrated. Eosinophils secrete CD30 ligand that is capable of binding to CD30 positive HD cells. The activation of TRAF2, followed by NF-kappaB, which occurs on CD30L/CD30 binding, may explain the neoplastic proliferation and apoptosis protection of HD cells. TRAF2 is also activated by EBV-LMP expression, which is detectable in the majority of MC but not NS cases. In addition to the possibility that eosinophils are only passive indicators for other unknown prognostic determinants, it may be concluded that the positive clinical outcome of eosinophilia-negative NS cases could be due to lower NF-kappaB activity.

    Aims To explore and to compare the outcome of patients diagnosed with stage II/III/IV and stage III/IV endometrioid adenocarcinoma (EAC) with their serous carcinoma (USC) counterparts. Materials and methods A total of 107 patients (73 EAC and 34 USC) were evaluated. For statistical analysis, the following baseline variables were considered for their prognostic value: the patient’s age at presentation, the tumor size, the depth of myometrial invasion (MI), the lympho-vascular involvement (LVI) and the USC and the EAC subtypes (considered as binary variables). Disease free survival (DFS), death of disease (DOD) and overall survival (OS) were assessed using univariate and multiple Cox proportional hazards models. Results In univariate analysis, USC tends to recur more frequently than EAC (p = 0.004), a finding that disappeared in multivariate analysis. Furthermore, tumor histology had no significance in predicting the tumor outcomes. Among all of the prognostic factors and after adjusting for the aforementioned variables, MI ≥50% was the only independent factor in predicting DOD in stages II/III/IV (p = 0.009) and in stages III/IV (p = 0.004). MI was also an independent predictive factor for OS (p = 0.02) and early recurrences in stages III/IV. LVI was the only independent factor in predicting recurrences (p = 0.004) in stages II/III/IV but not in stages III/IV. Conclusion Based on our study, tumor histology was not a significant factor in predicting disease outcome in stages II/III/IV and II/IV. Despite our limited sample size, we believe that our findings provide meaningful insights into the clinical study of endometrial cancer patients which in turn warrants further investigation.

    OBJECTIVE--To describe the natural course of recent acute low back pain in terms of both morbidity (pain, disability) and absenteeism from work and to evaluate the prognostic factors for these outcomes. DESIGN--Inception cohort study. SETTING--Primary care. PATIENTS--103 patients with acute localised non-specific back pain lasting less than 72 hours. MAIN OUTCOME MEASURES--Complete recovery (disappearance of both pain and disability) and return to work. RESULTS--90% of patients recovered within two weeks and only two developed chronic low back pain. Only 49 of 100 patients for whom data were available had bed rest and 40% of 75 employed patients lost no time from work. Proportional hazards regression analysis showed that previous chronic episodes of low back pain, initial disability level, initial pain worse when standing, initial pain worse when lying, and compensation status were significantly associated with delayed episode recovery. These factors were also related to absenteeism from work. Absenteeism from work was also influenced by job satisfaction and gender. CONCLUSIONS--The recovery rate from acute low back pain was much higher than reported in other studies. Those studies, however, did not investigate groups of patients enrolled shortly after the onset of symptoms and often mixed acute low back pain patients with patients with exacerbations of chronic pain or sciatica. Several sociodemographic and clinical factors were of prognostic value in acute low back pain. Factors which influenced the outcome in terms of episode recovery (mainly physical severity factors) were only partly predictive of absenteeism from work. Time off work and return to work depended more on sociodemographic and job related influences. PMID:8148683

    Survival for patients with glioblastoma multiforme is short, and current treatments provide limited benefit. Therefore, there is interest in conducting phase 2 trials of experimental treatments in newly diagnosed patients. However, this requires historical data with which to compare the experimental therapies. Knowledge of prognostic markers would also allow stratification into risk groups for phase 3 randomized trials. In this retrospective study of 832 glioblastoma multiforme patients enrolled into prospective clinical trials at the time of initial diagnosis, we evaluated several potential prognostic markers for survival to establish risk groups. Analyses were done using both Cox proportional hazards modeling and recursive partitioning analyses. Initially, patients from 8 clinical trials, 6 of which included adjuvant chemotherapy, were included. Subsequent analyses excluded trials with interstitial brachytherapy, and finally included only nonbrachytherapy trials with planned adjuvant chemotherapy. The initial analysis defined 4 risk groups. The 2 lower risk groups included patients under the age of 40, the lowest risk group being young patients with tumor in the frontal lobe only. An intermediate-risk group included patients with Karnofsky performance status (KPS) >70, subtotal or total resection, and age between 40 and 65. The highest risk group included all patients over 65 and patients between 40 and 65 with either KPS < 80 or biopsy only. Subgroup analyses indicated that inclusion of adjuvant chemotherapy provides an increase in survival, although that improvement tends to be minimal for patients over age 65, for patients over age 40 with KPS less than 80, and for those treated with brachytherapy.

    Vancomycin hydrochloride (VCM) is widely used for treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections. However, this drug can cause sever adverse reactions, such as red neck syndrome, nephrotoxicity and ototoxicity. Thus, therapeutic drug monitoring (TDM) was bringing into effect for well effectiveness and to prevent side effects. In Kanto Medical Center NTT EC, TDM of VCM has been brought into effect since 1994. The date were accumulated from 200 patients. In this study, the retrospective research was carried out based on 117 cases selected from the above accumulated data, and then several factors such as VCM inducing side effect, a therapeutic effect, and the forecast of pharmacokinetic parameter using laboratory data were examined. Consequently, the high blood concentration trough level, the high value after 1 to 2 hours infusion, and the extension of t1/2 were brought forward as a nephrotoxicity causing factor, and more over each laboratory data (BUN, Cr, GOT, GPT, gamma-GTP, T-BiL, ALP, LDH) was high before infusion of VCM in patients with renal dysfunction. High value T-Bil and lower value TP were brought forward in patients with hepatic dysfunction, and high eosinophils and high blood concentration were brought forward after 1 or 2 hours infusion. In relation to side effects, it was found that the outbreak rate of side effects is high in patients with a complication of hypertension or diabetes. The administration term was considered as a factor which influences the therapeutic effects. The unchanged effect was 10.9 +/- 7.9 days, the improved effect was 14.6 +/- 9.3 days, the remarkably improved effect was 17.7 +/- 14.1 days. As the administration term gets longer, the improvement rate was recognized to be an upward tendency. The difference in significant effects was recognized between unchanged and remarkably unchanged (p < 0.05) effects.

    There is a growing epidemiological literature focusing on the association between psychosocial stress and human immunodeficiency virus (HIV) disease progression or acquired immunodeficiency syndrome (AIDS), but inconsistent findings have been published. We aimed to quantify the association between adverse psychosocial factors and HIV disease progression. We searched Medline; PsycINFO; Web of Science; PubMed up to 19 January 2009, and included population studies with a prospective design that investigated associations between adverse psychosocial factors and HIV disease progression or AIDS. Two reviewers independently extracted data on study characteristics, quality, and estimates of associations. The overall meta-analysis examined 36 articles including 100 psychosocial and disease related relationships. It exhibited a small, but robust positive association between adverse psychosocial factors and HIV progression (correlation coefficient as combined size effect 0.059, 95% confidence interval 0.043-0.074, p<0.001). Notably, sensitivity analyses showed that personality types or coping styles and psychological distress were more strongly associated with greater HIV disease progression than stress stimuli per se, and that all of the immunological and clinical outcome indicators (acquired immunodeficiency syndrome stage, CD4+ T-cell decline, acquired immunodeficiency syndrome diagnosis, acquired immunodeficiency syndrome mortality, and human immunodeficiency virus disease or acquired immunodeficiency syndrome symptoms) except for viral load exhibited detrimental effects by adverse psychosocial factors. In conclusion, the current review reveals a robust relationship between adverse psychosocial factors and HIV disease progression. Furthermore, there would appear to be some evidence for particular psychosocial factors to be most strongly associated with HIV disease progression.

    The purpose of this study was to evaluate the prognostic value of Sestirn2 in patients with non-small cell lung cancer (NSCLC). Quantitative real-time ( RT-PCR) and western blot were performed to investigate the mRNA and protein expression of Sestirn2 in NSCLC and corresponding non-cancerous tissues. Immunohistochemistry was used to detect the expression of Sestirn2 in 210 NSCLC tissue samples. Overall survival was calculated by the Kaplan-Meier method and analyzed by the log-rank test between different groups. The results indicated that the Sestirn2 expression was significantly lower in NSCLC tissues than the corresponding non-cancerous lung tissues. Low Sestirn2 expression was related to poor tumor differentiation, advanced TNM stage, and lymph node metastasis. Patients with high Sestirn2 expression had longer overall survival than those with low expression levels, which was consistent with the results of the subgroup analysis. Multivariate analysis showed that high Sestirn2 expression was a favorable prognostic factor for NSCLC patients. Our study indicated that Sestirn2 could play an important role in the observation of prognosis in NSCLC and might be a valuable marker for predicting the treatment outcome in patients with NSCLC.

The results showed that the RBX1 expression was significantly higher in NSCLC tissues than the corresponding non-cancerous lung tissues. High RBX1 expression was related to poor tumor differentiation, advanced TNM stage, and lymph node metastasis. Patients with high RBX1 expression had poor overall survival than those with high expression levels, which was consistent with the results of the subgroup analysis.

    The toxicity of low-dose total body irradiation (LTBI), the prognostic factors related to survival and relapse-free survival, and the efficacy of treatment given for relapse after LTBI were analyzed in 68 patients with non-Hodgkin lymphoma (NHL) treated at the Rotterdamsch Radiotherapeutisch Instituut. All patients received LTBI between 1973 and 1979. The patient material was heterogeneous with respect to malignancy grade, stage, age, and therapy given before or after LTBI; the unifying principle was that all patients received LTBI and had symptomatic NHL. Analysis of prognostic variables with Cox's model revealed grade (p less than 0.001) and age (p = 0.004) as predictors for survival and grade (p less than 0.001) and dose of LTBI (p = 0.056) as predictors for relapse-free survival after LTBI. No subjective toxicity was observed during or after LTBI treatment. Hematologic toxicity was dose-limiting and was increased if patients had received cytotoxic treatment before LTBI. LTBI-related hematologic toxicity was lower in patients with low-grade NHL than in those with intermediate or high-grade NHL, was limited in time, and recovered in all patients. Patients relapsing after LTBI received a variety of therapies. Response rates were high, but of short duration, especially in intermediate or high-grade NHL. Duration of response was progressively shorter after multiple relapses. PMID:2198791

    Background: Men with screen-detected prostate cancer can choose to undergo immediate curative treatment or enter into an expectant management programme. We quantified how the benefits and harms of immediate treatment vary according to the prognostic factors of clinical T-stage, Gleason score, and patient age. Methods: A microsimulation model based on European Randomized Study of Screening for Prostate Cancer data was used to predict the benefits and harms of immediate treatment versus delayed treatment of local–regional prostate cancer in men aged 55–74 years. Benefits included life-years gained and reduced probability of death from prostate cancer. Harms included lead time and probability of overdiagnosis. Results: The ratio of mean lead time to mean life-years gained ranged from 1.8 to 31.2, and the additional number of treatments required per prostate cancer death prevented ranged from 0.3 to 11.6 across the different prognostic groups. Both harm–benefit ratios were lowest, most favourable, for men aged 55–59 years and diagnosed with moderate-risk prostate cancer. Ratios were high for men aged 70–74 years regardless of clinical T-stage and Gleason score. Conclusion: Men aged 55–59 years with moderate-risk prostate cancer are predicted to derive greatest benefit from immediate curative treatment. Immediate treatment is least favourable for men aged 70–74 years with either low-risk or high-risk prostate cancer. PMID:23674085

Design Population based nested case-control study. Setting Ontario, Canada. Participants 91 378 older adults with a history of physician diagnosed retinal disease identified between 1 April 2006 and 31 March 2011. Cases were 1477 patients admitted to hospital for ischaemic stroke, 2229 admitted for an acute myocardial infarction, 1059 admitted or assessed in an emergency department for venous thromboembolism, and 2623 admitted for congestive heart failure. Event-free controls (at a ratio of 5:1) were matched to cases on the basis of year of birth, sex, history of the outcome in the previous 5 years, and diabetes. Main exposure measure Exposure to vascular endothelial growth factor inhibiting drugs identified within 180 days before the index date. Results After adjustment for potential confounders, participants who had ischaemic stroke, acute myocardial infarction, congestive heart failure, or venous thromboembolism were not more likely than control participants to have been exposed to either bevacizumab (adjusted odds ratios of 0.95 (95% confidence interval 0.68 to 1.34) for ischaemic stroke, 1.04 (0.77 to 1.39) for acute myocardial infarction, 0.81 (0.49 to 1.34) for venous thromboembolism, and 1.21 (0.91 to 1.62) for congestive heart failure) or ranibizumab (adjusted odds ratios 0.87 (0.68 to 1.10) for ischaemic stroke, 0.90 (0.72 to 1.11) for acute myocardial infarction, 0.88 (0.67 to 1.16) for venous thromboembolism, and 0.87 (0.70 to 1.07) for congestive heart failure). Similarly, a secondary analysis of exclusive users of bevacizumab or ranibizumab showed no differences in risk between the two drugs (adjusted odds ratios for bevacizumab relative to ranibizumab of 1.03 (0.67 to 1.60) for ischaemic stroke, 1.23 (0.85 to 1.77) for acute myocardial infarction, 0.92 (0.51 to 1.69) for venous thromboembolism, and

Greater c/b ratio was significantly associated with later Severin class III hip. Using receiver operating characteristics curve, a c/b ratio greater than 0.72 at 6 months and 1 year postoperatively can predict the possibility of a class III hip in 30 and 60% of patients, respectively.

    During the incipient steps of periodontal treatment, clinicians are usually asked to predict the prognosis of teeth with compromised periodontium. The aim of this literature review was to investigate the association between periodontal Prognosis, Tooth Loss and risk indicators, such as smoking and genetics. Results showed that the definition of good prognosis has much higher predictability than the one for questionable prognosis. Several risk indicators for periodontal prognosis and tooth loss are discussed as well as different definitions of questionable prognosis and their success in predicting tooth loss. In conclusion, the major focus of future studies should be to construct simplified prognostic models with high predictability that will increase the confidence of dentists and periodontists when assigning teeth prognosis.

    To evaluate oncologic and functional outcomes and prognostic factors in patients with locally advanced hypopharyngeal cancer included in an induction chemotherapy (ICT)-based larynx preservation program in daily clinical practice. All patients with locally advanced (T3/4, N0-3, M0) hypopharyngeal squamous cell carcinoma, technically suitable for total pharyngo-laryngectomy, treated by docetaxel (75 mg/m(2), day 1), cisplatin (75 mg/m(2), day 1) and 5-fluorouracil (750 mg/m(2)/day, day 1-5) (TPF)-ICT (2-3 cycles) for larynx preservation at our institution between 2004 and 2013, were included in this retrospective study. Prognostic factors of oncologic (overall, cause-specific and recurrence-free survival: OS, SS and RFS) and functional (dysphagia outcome and severity scale, permanent enteral nutrition, larynx preservation) outcomes were assessed in univariate and multivariate analyses. A total of 53 patients (42 men and 11 women, mean age 58.6 ± 8.2 years) were included in this study. Grade 3-4 toxicities were experienced by 17 (32 %) patients during ICT. The rate of poor response (response <50 % without larynx remobilization) to ICT was 10 %. At 5 years, OS, SS and RFS rates were 56, 60 and 54 %, respectively. Four patients required definitive enteral nutrition (permanent enteral tube feeding). The rate of patients alive, disease-free and with a functional larynx at 2 years was 58 %. T4 tumor stage (p = 0.005) and response to ICT <50 % (p = 0.02) were independent prognostic factors of OS. Response to ICT was significantly associated with the risk of permanent enteral nutrition (p = 0.04) and larynx preservation (p = 0.01). In daily clinical practice, a TPF-ICT-based larynx preservation protocol can be used in patients with locally advanced hypopharyngeal cancer with satisfactory results in terms of tolerance, efficacy and oncologic and functional outcomes.

    The International Prognostic Score (IPS) is the most widely used system to date for identifying risk groups for the outcome of patients with advanced Hodgkin lymphoma, although important limitations have been recognized. We analyzed the value of the IPS in a series of 311 patients with advanced classical Hodgkin lymphoma (cHL) (Ann Arbor stage III, IV or stage II with B symptoms and/or bulky masses) treated with first-line chemotherapy including adriamycin (adriamycin, bleomycin, vinblastine, dacarbazine [ABVD] or equivalent variants). In univariate and multivariate analyses, stage IV disease and age ≥ 45 years were the only factors with independent predictive significance for overall survival (OS) (p = 0.002 and p < 0.001, respectively). Stage IV was still significant for freedom from progression (FFP) (p = 0.001) and age ≥ 45 years was borderline significant (p = 0.058). IPS separates prognostic groups, as in the original publication, but this is mainly due to the high statistical significance of stage IV and age ≥ 45 years. Moreover, the combination of these two factors enables a simpler system to be constructed that separates groups with different FFP and OS. In conclusion, in our series, stage IV and age ≥ 45 years are the key prognostic factors for the outcome of advanced cHL.

    We aim to describe trends in net survival (NS) and to assess the prognostic factors among women with de novo metastatic breast cancer (MBC) according to human epidermal growth factor receptor 2 (HER2) and hormone receptor (HR) status. Data on women suffering from de novo MBC and diagnosed from 1998 to 2009 were provided by the Côte-d'Or breast cancer registry. NS was described using the Pohar Perme estimator and prognostic factors were investigated in a generalised linear model. We identified 232 patients (mean age = 64.7). Median NS was 29.2 months, 1- and 5-year NS were 76% and 26% respectively. The survival trend in patients with HER2-positive tumours who did not receive trastuzumab was similar to that in women with triple-negative tumours. A higher relative excess risk of death by cancer was observed for high-grade tumours [RER, relative excess rates = 1.76 (95% CI, confidence intervals: 1.17-2.62) for Scarff Bloom Richardson grade 3 vs. 1 + 2], while a lower risk was observed for luminal tumours [RER = 0.49 (95% CI: 0.27-0.89)] and HER2-positive tumours treated with trastuzumab [RER = 0.28 (95% CI: 0.14-0.59)], both compared with triple-negative tumours. Surgery of the primary tumour was associated with better survival [RER = 0.43 (95% CI: 0.28-0.68)]. With half of the women dead before 29 months, stage IV breast cancer still has a bleak outlook. Progress should continue with new target therapies for both HR and HER2 receptors.

    Early growth responsive gene 3 (EGR3) is a zinc-finger transcription factor and plays important roles in cellular growth and differentiation. We recently demonstrated estrogen-mediated induction of EGR3 in breast carcinoma cells. However, EGR3 has not yet been examined in breast carcinoma tissues and its significance remains unknown. Therefore, in this study, we examined biological functions of EGR3 in the breast carcinoma by immunohistochemistry, in vitro study, and nude mouse xenograft model. EGR3 immunoreactivity was detected in carcinoma cells in 99 (52%) out of 190 breast carcinoma tissues and was associated with the mRNA level. EGR3 immunoreactivity was positively associated with lymph node status, distant metastasis into other organs, estrogen receptor alpha, or EGR3 immunoreactivity in asynchronous recurrent lesions in the same patients, and was negatively correlated with tubule formation. EGR3 immunoreactivity was significantly associated with an increased risk of recurrence and adverse clinical outcome by both uni- and multivariate analyses. Egr3-expressing transformant cell lines derived from MCF-7 Tet-Off cells (Eg-10 and Eg-11) significantly enhanced the migration and invasion properties according to the treatment of doxycyclin, but did not significantly change the cell proliferation. Moreover, Eg-11 cells injected into athymic mice irregularly invaded into the adjacent peritumoral tissues, although Clt-7, which was stably transfected with empty vector as a control, demonstrated a well-circumscribed tumor. Eg-11 cells were significantly associated with invasive components and less tubule formation in the xenograft model. These results suggest that EGR3 plays an important role in estrogen-meditated invasion and is an independent prognostic factor in breast carcinoma. PMID:17639044

    Background Long-term exposure to anti-tuberculosis medication increases risk of adverse drug reactions and toxicity. The objective of this investigation was to determine factors associated with anti-tuberculosis adverse drug reactions in Lima, Peru, with special emphasis on MDR-TB medication, HIV infection, diabetes, age and tobacco use. Methodology and Results A case-control study was performed using information from Peruvian TB Programme. A case was defined as having reported an anti-TB adverse drug reaction during 2005–2010 with appropriate notification on clinical records. Controls were defined as not having reported a side effect, receiving anti-TB therapy during the same time that the case had appeared. Crude, and age- and sex-adjusted models were calculated using odds ratios (OR) and 95% confidence intervals (95%CI). A multivariable model was created to look for independent factors associated with side effect from anti-TB therapy. A total of 720 patients (144 cases and 576 controls) were analyzed. In our multivariable model, age, especially those over 40 years (OR = 3.93; 95%CI: 1.65–9.35), overweight/obesity (OR = 2.13; 95%CI: 1.17–3.89), anemia (OR = 2.10; IC95%: 1.13–3.92), MDR-TB medication (OR = 11.1; 95%CI: 6.29–19.6), and smoking (OR = 2.00; 95%CI: 1.03–3.87) were independently associated with adverse drug reactions. Conclusions Old age, anemia, MDR-TB medication, overweight/obesity status, and smoking history are independent risk factors associated with anti-tuberculosis adverse drug reactions. Patients with these risk factors should be monitored during the anti-TB therapy. A comprehensive clinical history and additional medical exams, including hematocrit and HIV-ELISA, might be useful to identify these patients. PMID:22110689

    Background Recent studies among males have reported a genotype-environment interaction (G × E) in which low-activity alleles at the monoamine oxidase A (MAOA) locus conferred greater sensitivity to the effects of childhood adversity on risk for conduct disorder (CD). So far, few studies of females have controlled for gene-environment correlation or used females heterozygous for this X-linked gene. Method Logistic regression analysis of a sample of 721 females ages 8-17 years from the longitudinal Virginia Twin Study of Adolescent Behavioral Development (VTSABD) assessed the additive effects of MAOA genotypes on risk for CD, together with the main effect of childhood adversity and parental antisocial personality disorder (ASP), as well as the interaction of MAOA with childhood adversity on risk for CD. Results A significant main effect of genotype on risk for CD was detected, where low-activity MAOA imparted the greatest risk to CD in girls while controlling for the significant effects of maternal ASP and childhood adversity. Significant G × E with weak effect was detected when environmental exposure was untransformed, indicating a higher sensitivity to childhood adversity in the presence of the high-activity MAOA allele. The interaction was no longer statistically significant after applying a ridit transformation to reflect the sample sizes exposed at each level of childhood adversity. Conclusions The main effect of MAOA on risk for CD in females, its absence in males and directional difference of interaction is suggestive of genotype-sex interaction. As the effect of G × E on risk for CD was weak, its inclusion is not justified. PMID:18752729

    Background The G1 cell cycle inhibitors tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been identified as promising biomarkers for the prediction of adverse outcomes including renal replacement therapy (RRT) and mortality in critically ill adult patients who develop acute kidney injury (AKI). However, the prognostic value of urinary TIMP-2 and IGFBP7 in neonatal and pediatric AKI for adverse outcome has not been investigated yet. Methods The product of the urinary concentration of TIMP-2 and IGFBP7 ([TIMP-2]•[IGFBP7]) was assessed by a commercially available immunoassay (NephroCheck™) in a prospective cohort study in 133 subjects aged 0–18 years including 46 patients with established AKI according to pRIFLE criteria, 27 patients without AKI (non-AKI group I) and 60 apparently healthy neonates and children (non-AKI group II). AKI etiologies were: dehydration/hypovolemia (n = 7), hemodynamic instability (n = 7), perinatal asphyxia (n = 9), septic shock (n = 7), typical hemolytic-uremic syndrome (HUS; n = 5), interstitial nephritis (n = 5), vasculitis (n = 4), nephrotoxic injury (n = 1) and renal vein thrombosis (n = 1). Results When AKI patients were classified into pRIFLE criteria, 6/46 (13%) patients fulfilled the criteria for the category “Risk”, 13/46 (28%) for “Injury”, 26/46 (57%) for “Failure” and 1/46 (2%) for “Loss”. Patients in the “Failure” stage had a median 3.7-fold higher urinary [TIMP-2]•[IGFBP7] compared to non-AKI subjects (P<0.001). When analyzed for AKI etiology, highest [TIMP-2]•[IGFBP7] values were found in patients with septic shock (P<0.001 vs. non-AKI I+II). Receiver operating characteristic (ROC) curve analyses in the AKI group revealed good performance of [TIMP-2]•[IGFBP7] in predicting 30-day (area under the curve (AUC) 0.79; 95% CI, 0.61–0.97) and 3-month mortality (AUC 0.84; 95% CI, 0.67–0.99) and moderate performance in predicting RRT

    Purpose To examine heterogeneous breast cancer through intravoxel incoherent motion (IVIM) histogram analysis. Materials and methods This HIPAA-compliant, IRB-approved retrospective study included 62 patients (age 48.44±11.14 years, 50 malignant lesions and 12 benign) who underwent contrast-enhanced 3 T breast MRI and diffusion-weighted imaging. Apparent diffusion coefficient (ADC) and IVIM biomarkers of tissue diffusivity (Dt), perfusion fraction (fp), and pseudo-diffusivity (Dp) were calculated using voxel-based analysis for the whole lesion volume. Histogram analysis was performed to quantify tumour heterogeneity. Comparisons were made using Mann–Whitney tests between benign/malignant status, histological subtype, and molecular prognostic factor status while Spearman’s rank correlation was used to characterize the association between imaging biomarkers and prognostic factor expression. Results The average values of the ADC and IVIM biomarkers, Dt and fp, showed significant differences between benign and malignant lesions. Additional significant differences were found in the histogram parameters among tumour subtypes and molecular prognostic factor status. IVIM histogram metrics, particularly fp and Dp, showed significant correlation with hormonal factor expression. Conclusion Advanced diffusion imaging biomarkers show relationships with molecular prognostic factors and breast cancer malignancy. This analysis reveals novel diagnostic metrics that may explain some of the observed variability in treatment response among breast cancer patients. PMID:26615557

    Patients with Gaucher type 1 (GD1) throughout Argentina were enrolled in the Argentine bone project to evaluate bone disease and its determinants. We focused on presence and predictors of bone lesions (BL) and their relationship to therapeutic goals (TG) with timing and dose of enzyme replacement therapy (ERT). A total of 124 patients on ERT were enrolled in a multi-center study. All six TG were achieved by 82% of patients: 70.1% for bone pain and 91.1% for bone crisis. However, despite the fact that bone TGs were achieved, residual bone disease was present in 108 patients on ERT (87%) at time 0. 16% of patients showed new irreversible BL (bone infarcts and avascular osteonecrosis) despite ERT, suggesting that they appeared during ERT or were not detected at the moment of diagnosis. We observed 5 prognostic factors that predicted a higher probability of being free of bone disease: optimal ERT compliance; early diagnosis; timely initiation of therapy; ERT initiation dose ≥45 UI/kg/EOW; and the absence of history of splenectomy. Skeletal involvement was classified into 4 major phenotypic groups according to BL: group 1 (12.9%) without BL; group 2 (28.2%) with reversible BL; group 3 (41.9%) with reversible BL and irreversible chronic BL; and group 4 (16.9%) with acute irreversible BL. Our study identifies prognostic factors for achieving best therapeutic outcomes, introduces new risk stratification for patients and suggests the need for a redefinition of bone TG. Am. J.

    The purpose of this study was to identify the prognostic factors for disease-free survival (DFS) and recurrence patterns in Chinese women with squamous cell carcinoma of the vulva treated with primary surgery. From 1980 through 2002, 100 patients with invasive squamous cell carcinoma of the vulva treated with primary surgery were included in this retrospective study. Survival analyses included the Kaplan-Meier method, log-rank test, and Cox proportional hazards model. The 5- and 10-year DFS rates were 66.5% and 45.2%, respectively. Among all the tumor-related variables age, International Federation of Gynecology and Obstetrics stage, lymphovascular space invasion, and lymph node status were found to be significant predictors of DFS for the univariate analysis. Multivariate analysis proved that age (risk ratio, 6.572; 95% confidence interval, 1.759-24.546) and lymph nodes metastasis (risk ratio, 4.178; 95% confidence interval, 1.358-12.855) were the most significant prognostic factors of DFS (P < 0.05). The overall recurrence rate was 34.0% (34/100). Among the patients with recurrences, the locations of the recurrent disease were as follows: local recurrence in 20 (58.8%), groin recurrence in 2 (5.9%), local and groin in 1 (2.9%), distant metastases in 5 (14.7%), and local recurrence and distant metastases in 5 (14.7%); data were missing for 1 (2.9%) patients. Older age and lymph nodes metastases were the independent predictors of poor prognosis for patients with invasive squamous cell carcinoma of the vulva treated with primary surgery. Local recurrence was the main recurrence pattern after primary surgery which would be improved by multidisciplinary treatment.

    Early identification of children at high risk of diarrhoea-associated dehydration would be of great value to health care workers in developing countries. To identify prognostic factors for life-threatening dehydration, we carried out a case-control study among under-2-year-olds in Porto Alegre, Brazil. Cases were 192 children admitted to hospital with moderate or severe dehydration, while controls were children matched to controls by neighbourhood and age, who experienced nondehydrating diarrhoea in the week preceding the interview. The following variables were significantly associated with an increased risk of dehydration, after adjustment for age and other confounding variables: absence of the father from the home; low paternal education level; young age; maternal age 25-29 years or less than 20 years; mother of mixed race; high birth order; short birth interval; low birth weight; stunting, underweight and wasting; lack of breast-feeding; presence of other under-5-year-olds in the home; families with 4-5 members; lack of antenatal care; less than three doses of diphtheria-pertussis-tetanus or poliomyelitis vaccine; previous admission to hospital; use of medicines during the fortnight prior to the episode; and living in an unclean home. The associations were particularly strong (P less than 0.001) for the child's age, birth weight and other anthropometric indicators, birth interval, and feeding mode. In terms of their sensitivity and specificity, however, these prognostic factors were not as effective as early signs and symptoms for predicting the outcome of the episode. PMID:1394780

    AIM: To determine the expression of miR-422a in colorectal cancer (CRC) tissues and to further explore the prognostic value and function of miR-422a in CRC carcinogenesis. METHODS: miR-422a expression was analyzed in 102 CRC tissues and paired normal mucosa adjacent to carcinoma by quantitative real-time PCR. The relationship of miR-422a expression with clinicopathological parameters was also analyzed. Kaplan-Meier analysis and Cox multivariate analysis were performed to estimate the potential role of miR-422a. Cell proliferation, migration, and invasion were used for in vitro functional analysis of miR-422a. RESULTS: The levels of miR-422a were dramatically reduced in CRC tissues compared with normal mucosa (P < 0.05), and significantly correlated with local invasion (P = 0.004) and lymph node metastasis (P < 0.001). Kaplan-Meier survival and Cox regression multivariate analyses revealed that miR-422a expression (HR = 0.568, P = 0.015) and clinical TNM stage (HR = 2.942, P = 0.003) were independent prognostic factors for overall survival in CRC patients. Furthermore, in vitro experiments showed that overexpression of miR-422a inhibited the proliferation, migration, and invasion of SW480 and HT-29 cells. CONCLUSION: Down-regulation of miR-422a may serve as an independent prognosis factor in CRC. MiR-422a functions as a tumor suppressor and regulates progression of CRC. PMID:27350737

    Background: With the continuing increase in the use of definitive stereotactic radiosurgery (SRS) for patients with limited brain metastases (BM), clinicians need more specific prognostic tools. We investigated clinical predictors of outcomes in patients with limited breast cancer BM treated with SRS alone. Methods and Materials: We identified 136 patients with breast cancer and 1-3 BM who underwent definitive SRS for 186 BM between 2000 and 2012. The Kaplan-Meier method was used to assess overall survival (OS), regional failure (RF), and local failure (LF). Associations between clinical factors and outcomes were tested using Cox regression. A point scoring system was used to stratify patients based on OS, and the predictive power was tested with concordance probability estimate (CPE). Results: The median OS was 17.6 months. The 12-month RF and LF rates were 45% and 10%, respectively. On multivariate analysis, >1 lesion (hazard ratio [HR] = 1.6, P=.02), triple-negative (TN) disease (HR=2.0, P=.006), and active extracranial disease (ED) (HR=2.7, P<.0001) were significantly associated with worse OS. The point score system was defined using proportional simplification of the multivariate Cox proportional hazards regression function. The median OS for patients with 3.0-4.0 points (n=37), 4.5-5.5 points (n=28), 6.0-6.5 points (n=37), and 8-8.5 points (n=34) were 9.2, 15.6, 25.1, and 45.1 months, respectively (P<.0001, CPE = 0.72). Active ED (HR=2.4, P=.0007) was significantly associated with RF. Higher risk for LF was significantly associated with larger BM size (HR=3.1, P=.0001). Conclusion: Patients with >1 BM, active ED, and TN had the highest risk of death after SRS. Active ED is an important prognostic factor for OS and intracranial control.
