    Objectives The purpose of this study is to analyze clinical impact factors on the survival rate, and to acquire basic clinical data for the diagnosis of oral cancer, for a determination of the treatment plan with long-term survival in oral cancer patients. Materials and Methods Through a retrospective review of the medical records, the factors for long-term survival rate were analyzed. Thirty-seven patients, among patient database with oral cancer treated in the Department of Oral and Maxillofacial Surgery at Pusan National University Hospital within a period from March 1998 to March 2008, were selected within the study criteria and were followed-up for more than 5 years. The analyzed factors were gender, age, drinking, smoking, primary tumor site, type of cancer, TNM stage, recurrence of affected region, and metastasis of cervical lymph node. The 5-year survival rate on the impact factors was calculated statistically using the Kaplan-Meier method. Results By classification of clinical TNM at the 1st visit, there were 11 (29.7%) cases for stage I, 11 (29.7%) cases for stage II, 3 (8.1%) cases for stage III, and 12 (32.5%) cases for stage IV. The 5-year survival rate of total oral cancer patients after the operation were 75.7%, pathological TNM stage related 5-year survival rate were as follows: stage I 90.0%, stage II 81.8%, stage III 100% and stage IV 45.5%; in which the survival rate difference by each stage was significantly observed. The recurrence of cervical lymph node was the significant impact factor for the survival rate, because only 30.0% the survival rate in recurrent cases existed. During the follow-up, there were 15 (40.5%) patients with confirmed recurrence, and the 5-year survival rate of these patients was decreased as 46.7%. Conclusion The classification of clinical and pathological TNM stage, local recurrence after surgery, and metastasis of cervical lymph node after surgery were analyzed as the 3 most significant factors.

    Purpose Improvement in breast cancer survival has been observed in recent decades in the U.S., but it is unclear if similar survival gains are consistent across breast cancer subtypes, especially with regards to more advanced stages of the disease. Methods Data were from 13 population-based cancer registries participating in the Surveillance, Epidemiology and End Results (SEER) program, consisting of women between 20–79 years of age diagnosed with invasive breast cancer between 1992 and 2008. 2-year (1992–2008) and 5-year (1992–2006) breast cancer cause-specific survival rates were calculated and stratified by estrogen receptor (ER)/progesterone receptor (PR) status, stage and race. Annual percent changes in survival rates were assessed. Results From 1992 through 1998–1999, 5-year and 2-year cause specific survival rates significantly improved across ER+/PR+, ER−/PR− and ER+/PR− subtypes, with an annual increase ranging from 0.5%–1.0%. From 1998–1999 to 2006, different patterns were observed by ER/PR subtypes with survival rates slightly improving for ER+/PR+, continuing to improve at a rate of 0.5% per year for ER−/PR−, and dropping 0.3% annually for ER+/PR− No significant survival gains were experienced by patients with ER−/PR+ cancer during the study period. In terms of advanced diseases, greatest annual increases in survival rates were seen for patients with stage III–IV ER+/PR+ and ER−/PR− tumors but less progress was observed for advanced ER+/PR− breast cancers. Conclusion Steady improvements in survival rates for breast cancer have been achieved over the past several decades. However, 5-year survival rates for stage IV disease remained dismally below 20% for most ER/PR subtypes. PMID:25164974

    The aim of the present study was to design a microscopy image analysis (MIA) system for predicting the 5-year survival of patients with laryngeal squamous cell carcinoma, employing histopathology images of lesions, which had been immunohistochemically (IHC) stained for p63 expression. Biopsy materials from 42 patients, with verified laryngeal cancer and follow-up, were selected from the archives of the University Hospital of Patras, Greece. Twenty six patients had survived more than 5 years and 16 less than 5 years after the first diagnosis. Histopathology images were IHC stained for p63 expression. Images were first processed by a segmentation method for isolating the p63-expressed nuclei. Seventy-seven features were evaluated regarding texture, shape, and physical topology of nuclei, p63 staining, and patient-specific data. Those features, the probabilistic neural network classifier, the leave-one-out (LOO), and the bootstrap cross-validation methods, were used to design the MIA-system for assessing the 5-year survival of patients with laryngeal cancer. MIA-system accuracy was about 90 % and 85 %, employing the LOO and the Bootstrap methods, respectively. The image texture of p63-expressed nuclei appeared coarser and contained more edges in the 5-year non-survivor group. These differences were at a statistically significant level (p < 0.05). In conclusion, this study has proposed an MIA-system that may be of assistance to physicians, as a second opinion tool in assessing the 5-year survival of patients with laryngeal cancer, and it has revealed useful information regarding differences in nuclei texture between 5-year survivors and non-survivors.

    The increasing aging and diabetes mellitus (DM) patients in dialysis population make the quality maintenance of dialysis an imperative issue. Recently, an increasing number of dialysis centers were run by private dialysis providers, many of which apply quality assurance programs and performance management systems to dialysis care. We studied patients in dialysis facilities in Taiwan run by a private chain to see clinical outcomes of centers operating under these systemic strategies. Hemodialysis patients from January 1, 2008 to December 31, 2012 in 25 dialysis facilities in Taiwan, which received the management and consultation from a dialysis service provider, NephroCare (NC), were included. Data pivotal to quality of dialysis were analyzed. During a 5-year interval, 5161 hemodialysis patients were included. For volume control, the proportion of patients with weight gain ≥4.5% decreases from 41.7% to 30.2%. Mean Kt/V is 1.74 ± 0.28. Mean albumin level is 3.92 ± 0.38 g/dL. Patients with phosphate <5.5 mg/dL is up to 71.8%. The mean hemoglobin level is 10.70 ± 1.40 g/dL. More than 80% of patients have adequate iron status. Further, 73% of patients use native arteriovenous fistula. Hospitalization-free survival rate was 56% at the fifth year. Patient survival rate at the fifth year was 66.4%. Overall clinical performances were maintained very stable in NC facilities from this temporal data analysis. The hospitalization and survival rate also compare favorably with those reported internationally. These results warrant further studies to justify the application of this kind of quality assurance programs and performance management systems in dialysis care.

    One thousand one hundred and thirty-six patients surviving for more than five years after radiotherapy were studied. The important prognostic factors are: lesion less than 5 cm in length, lesion located in the upper-third segment and lesion that is radiosensitive. The radiation dose given to long term survivors varies greatly, i.e., 2700 to 9300 rad. Yet, for the sensitive type of lesion, doses lower than 5000 rad could also effect a cure. The delivery of an optimum dose determined by serial examinations during radiotherapy could improve the result of treatment. For local recurrent lesions, the value of a second course of radiation is extremely limited and surgery is the only means to offer a cure. For metastasis in the lymph nodes, radiation offers some hope of cure, although the long term outcome may not be satisfactory. For second primary cancer of the esophagus, aggressive radiation still gives encouraging results.

    The purpose of the present study was to investigate alternative endpoints to the 5-year overall survival (OS) and locoregional control (LRC) for nasopharyngeal carcinoma (NPC). A total of 2,450 NPC patients were enrolled in this study, including 1,842 patients treated with two-dimensional (2D) radiotherapy (RT), 451 treated with 3D conformal RT (CRT) and 157 treated with intensity-modulated RT (IMRT). We sequentially calculated the 1-, 2-, 3- and 4-year survival rates using a life table and compared these with the 5-year survival rate using the McNemar method, with the survival rate of the last indifferent comparison being considered as the alternative endpoint. For 2D RT, stage I patients exhibited similar survival rates at 1 and 5 years (98.9 vs. 94.4%, respectively; P=0.125 for both OS and LRC); stage N3 patients exhibited similar 4-year OS (55.2 vs. 53.5%; P=1.000) and 2-year LRC (78.3 vs. 71.2%; P=0.125) to the 5-year OS and LRC. For IMRT, the 1-, 2-, 3-, 4- and 5-year OS and LRC rates in stage I/II NPC patients were 100, 98, 96, 94 and 94% for OS and 100, 98, 96, 96 and 96% for LRC, respectively. No significant differences were observed for all the comparisons. For stage III/IV NPC patients treated with IMRT, the 1-, 2-, 3-, 4- and 5-year rates were 99.1, 96.3, 92.5, 88.8 and 85.0% for OS and 98.1, 97.2, 95.3, 90.7 and 89.7% for LRC, respectively. Only the 4-year OS and LRC rates were indifferent from those at 5 years (P=0.125 for OS and P=1.00 for LRC). In conclusion, the 1-year OS and LRC for stage I NPC patients treated with 2D RT or stage I/II NPC patients treated with IMRT, the 4-year OS and 2-year LRC for stage N3 NPC patients treated with 2D RT and the 4-year OS and LRC for stage III/IV NPC patients treated with IMRT were determined as the alternative endpoints to the 5-year OS and LRC for NPC patients.

    Purpose A randomized trial of oblimersen plus fludarabine/cyclophosphamide (OBL-FC; n = 120) versus FC (n = 121) was conducted in patients with relapsed/refractory chronic lymphocytic leukemia (CLL). The primary end point was met: the complete response (CR) rate, defined as complete or nodular partial response, was significantly greater with OBL-FC than with FC (17% v 7%; P = .025). Among patients with CR, response duration was significantly longer with OBL-FC than with FC (median not reached; > 36 months v 22 months; P = .03). Maximum benefit with OBL-FC, including a four-fold increase in CR rate and a survival benefit with 3 years of follow-up (hazard ratio, 0.53; P = .05), was observed in patients with fludarabine-sensitive disease. We evaluated long-term survival and poststudy CLL therapy among all randomly assigned patients. Methods Poststudy CLL treatment information was collected. Patients were observed for survival for up to 5 years from the date of random assignment. Results Poststudy CLL treatment was balanced between arms. Intent-to-treat analysis of 5-year survival showed no significant between-treatment difference (hazard ratio, 0.87; P = .34). Among the greater than 40% of patients with complete or partial remission, a significant 5-year survival benefit was observed with OBL-FC (hazard ratio, 0.60; P = .038). Among patients with fludarabine-sensitive disease who had previously demonstrated maximum benefit with OBL-FC, the previously observed survival benefit improved: a 50% reduction in the risk of death was observed (P = .004). Conclusion In relapsed/refractory CLL, OBL combined with FC offers patients who achieve complete or partial remission, as well as those who have fludarabine-sensitive disease, a significant survival benefit.

    The incidence of malnutrition is widely held to be greater in the elderly, but this specific factor has not been extensively studied in elderly dialysis patients. In a 30-month follow-up prospective study, we evaluated the role of nutrition on the outcome of 290 stable hemodialysis (HD) outpatients aged older than 75 years followed up in 20 French HD centers (167 men, 123 women; age, 79.8 +/- 4.2 years; previous time on dialysis, 41 +/- 38 months). On the same day in January 1996, predialysis and postdialysis blood samples were collected according to recommended procedures for dialysis quantification. Normalized protein catabolic rate, dialysis adequacy parameters, and estimation of lean body mass (LBM; expressed as observed/expected LBM values [obs/exp LBM]) were computed from predialysis and postdialysis urea and creatinine levels. Overall survival rates were 80% and 65% after 1 and 2 years of follow-up, respectively, and were significantly less in patients with the lower quartile of obs/exp LBM. In univariate analysis using the Cox proportional hazards model, survival was significantly influenced by age, albumin level, prealbumin level, body mass index, and diabetes, but not by sex, Kt/V, duration of dialysis, cholesterol level, hemoglobin level, or obs/exp LBM. In multivariate analysis, no variable remained significant. Cardiovascular mortality accounted for 52.1% of the patient deaths. We conclude that in elderly HD patients, malnutrition influences overall survival despite adequate dialysis treatment.

    The main purpose of the present analysis is to assess the influence of introducing early nasal continuous positive airway pressure (nCPAP) treatment on cardiovascular recurrences and mortality in patients with a first-ever ischaemic stroke and moderate-severe obstructive sleep apnea (OSA) with an apnea-hypopnea index (AHI) ≥20 events h(-1) during a 5-year follow-up. Patients received conventional treatment for stroke and were assigned randomly to the nCPAP group (n = 71) or the control group (n = 69). Cardiovascular events and mortality were registered for all patients. Survival and cardiovascular event-free survival analysis were performed after 5-year follow-up using the Kaplan-Meier test. Patients in the nCPAP group had significantly higher cardiovascular survival than the control group (100 versus 89.9%, log-rank test 5.887; P = 0.015) However, and also despite a positive tendency, there were no significant differences in the cardiovascular event-free survival at 68 months between the nCPAP and control groups (89.5 versus 75.4%, log-rank test 3.565; P = 0.059). Early nCPAP therapy has a positive effect on long-term survival in ischaemic stroke patients and moderate-severe OSA.

    Introduction: 90% of the tumors in the head and neck are squamous-cell carcinomas (HNSCC), which have overall 5- year survival rate between 50% -60%. CD44 has been shown to be associated with the prognosis. Materials and Methods: Biopsy specimens of 51 patients with oral tongue SCC were evaluated by Immunohistochemistry (IHC) for the CD44 antibody. Results: There was no significant correlation between CD44 and survival (P=0.77), age (P=0.4), CD44 and lymph node metastasis (P=0.87), sex (P=0.947), smoking (P=0.287) and tumor size (P=0.813). However, there was significant correlation between smoking and survival. Conclusion: There are widespread discrepancies among the findings in the literature regarding the prognosis of CD44 expression in OCSCC. Our study shows that the expression of CD44 is not a marker of aggressive behavior in oral tongue SCC. Consequently, CD44 cannot be considered as handy tool to establish the tumor behavior, prognosis and 5- year survival rate of these tumors. PMID:28008391

    As a postoperative adjuvant chemotherapy for gastric cancer, we have administered a combination of NCS (Neocarzinostatin) and 5-FU (NF treatment method) and in this paper we have compiled the results obtained in patients who were treated for 5 years in an attempt to compare the 5-year survival rate with that of patients administered a combination of MMC and 5-FU (MF treatment group) and a control group administered no anticancer agents. As the selection of either NF or MF treatment was conducted on an annual basis, this study can be considered an historical controlled study. The results obtained are summarized as follows. On comparing the survival rate of the NF treatment group and the control group, the 5-year survival rate for all patients who underwent curative resection and all patients with histological stage III cancers and the curative resection PS (+) group, as well as the survival period of the non-resected patients, showed a statistically significant difference, indicating that the survival rate was higher in the NF group. On comparing the NF group and the MF group, although no statistically significant difference was observed between then based on a stratified analysis of all resected cases, histological stage differences and n.ps factors, etc., certain values tended to indicate a higher survival rate for the NF group. Moreover, the survival rate of the non-resected patients was more favorable in the NF group. These results confirm that NCS is useful for the treatment of stomach cancer and compares favorably with MMC. The appearance of side-effects was significantly lower in the NF group in comparison with the MF group and the number of patients who had to discontinue therapy was extremely low.

    Background: The aim of this study is to evaluate the long-term therapeutic gain of induction chemotherapy (IC) in locoregionally advanced nasopharyngeal carcinoma (NPC) in the era of intensity-modulated radiotherapy (IMRT). Methods: Data on 957 patients with stage T1-2N2-3 or T3-4N1-3 NPC treated with IMRT were retrospectively reviewed. Propensity score matching (PSM) method was adopted to balance influence of various covariates. Patient survival between IC and non-IC groups were compared. Results: For the 318 pairs selected from the original 957 patients by PSM, the median follow-up duration was 57.13 months (range, 1.27-78.1 months). The 5-year overall survival (OS), distant metastasis-free survival (DMFS), disease-free survival (DFS) and locoregional relapse-free survival (LRRFS) rates for IC group vs. non-IC group were 87.2% vs. 80.8% (P = 0.023), 88.1% vs. 83.2% (P = 0.071), 80.7% vs. 71.4% (P = 0.011) and 92.1% vs. 86.7% (P = 0.081), respectively. Multivariate analysis identify IC as an independent prognostic factor for OS (HR, 0.595; 95% CI, 0.397-0.891; P = 0.012) and DFS (HR, 0.627; 95% CI, 0.451-0.872; P = 0.006). After excluding the patients not receiving concurrent chemotherapy, IC was found to be an independent prognostic factor for OS (HR, 0.566; 95% CI, 0.368-0.872; P = 0.01), DMFS (HR, 0.580; 95% CI, 0.367-0.916; P = 0.02) and DFS (HR, 0.633; 95% CI, 0.444-0.903; P = 0.012). Conclusions: IC is an effective treatment modality for patients with stage T1-2N2-3 and T3-4N1-3 NPC, and the incorporation of IC with standard CCRT could achieve the best therapeutic gain.

    The purpose of this study was to evaluate the outcome of the diabetic foot reconstructed with free flaps and analyse the preoperative risk factors. This study reviews 121 cases of reconstructed diabetic foot in 113 patients over 9 years (average follow-up of 53.2 months). Patients' age ranged from 26 to 78 years (average, 54.6 years). Free flaps used were anterolateral thigh (ALT, 90), superficial circumflex iliac artery perforator (SCIP, 20), anteromedial thigh (AMT, 5), upper medial thigh (UMT, 3), and other perforator free flaps (3). Correlation between the surgical outcome and preoperative risk factors were analysed using logistic regression model. Total loss was seen in 10 cases and 111 free-tissue transfers were successful (flap survival rate of 91.7%). During follow-up, limb was eventually lost in 17 patients and overall limb salvage rate was 84.9% and the 5-year survival was 86.8%. Correlation between flap loss and 14 preoperative risk factors (computed tomography (CT) angiogram showing intact numbers of major vessels, history of previous angioplasty, peripheral arterial disease (PAD), heart problem, chronic renal failure (CRF), American Society of Anaesthesiologists (ASA) physical status classification system, smoking, body mass index (BMI), HBA1c, lymphocyte count, ankle-brachial index (ABI), osteomyelitis, C-reactive protein (CRP) level and whether taking immunosuppressive agents) were analysed. Significant odds ratio were seen in patients who underwent lower extremity angioplasties (odds ratio: 17.590, p<0.001), with PAD (odds ratio: 10.212, p=0.032) and taking immunosuppressive agents after kidney transplantation (odds ratio: 4.857, p<0.041). Diabetic foot reconstruction using free flaps has a high chance for success and significantly increases the 5-year survival rate. Risk factors such as PAD, history of angioplasties in the extremity and using immunosuppressive agents after transplant may increase the chance for flap loss.

    We report on the natural history of diaphanospondylodysostosis (DSD) in the longest known survivor. DSD is a rare form of autosomal recessive vertebral dysotosis recently identified to be caused by a mutation in the BMPER gene. This condition is characterized by absent or severely delayed ossification of vertebral bodies, short broad thorax, short neck, protuberant abdomen, marked respiratory insufficiency, and normal appendicular skeleton. It is one of a number of spinal dysostoses, which are a heterogeneous group of axial skeletal malformations occurring during blastogenesis with continued evolution after birth. Significant medical intervention and at-home support contributed to the long-term survival of our patient. The patient had tracheomalacia, which resulted in respiratory insufficiency with thoracic insufficiency syndrome (TIS). Tracheostomy and vertical expandable prosthetic titanium rib (VEPTR) insertion operations ameliorated his symptoms. In addition, comprehensive physical and occupational therapy was performed due to chronic hypotonia. A consistent feature of all described DSD cases thus far are renal findings of dysplasia, nephrogenic rests or nephroblastomatosis, and/or cysts. The patient's renal cysts were monitored with serial ultrasounds at approximately 6-month intervals. The patient was diagnosed with bilateral renal cysts by ultrasound as a neonate, with eventual diagnosis at approximately 20 months of age with nephroblastoma suggesting this maybe an intrinsic part of DSD. The lack of other cases with nephroblastoma is likely related to the previously reported short period of survival.

    A 5-year prospective study of intraoperative blood transfusion in 239 patients, most of whom had major spinal surgery, has been completed. Autotransfusion is safe, practical, and it reduces donor blood requirements and total blood loss by 50%. It eliminates host versus graft reactions and disease transmission. In 33 patients having major spinal surgery, the in vivo survival of autologous, homologous, and processed red blood cells (RBC) using the Cell Saver System were compared. The RBC survival studies were performed using chromium-51 isotope labeling technique. The long-term survival of processed RBCs was normal over a 30-day period. There was no significant difference in the survival rate of the three groups studied.

    Introduction The gradual shift of general paediatric surgery (GPS) provision from district general hospitals (DGH) to specialised units is well recognised in the UK. The consequences of centralisation include a reduction in exposure to GPS for current surgical trainees. The GPS practice of a DGH is examined here. Methods All operations performed on children aged under 5 years over a 5-year period were identified using the local electronic operation database. Electronic hospital records and clinic letters were accessed to collect data on demographics, operations performed and outcome measures. Results 472 GPS operations were performed on children between the age of 22 days and 5 years between 2009 and 2014, of which 43 were on an emergency basis and 105 were performed on patients aged less than 1 year. Three patients were admitted following day case surgery. Six patients were readmitted within 30 days. Complication rates for all procedures and the four most common procedures were similar to those found in published literature. Conclusions GPS for patients aged less than 5 years is comparatively safe in the DGH setting. The training opportunities available at DGHs are invaluable to surgical trainees and vital for sustaining the future provision of GPS by such hospitals. PMID:27269243

    Introduction: The Disease Management Project Breast Cancer (DMP Breast Cancer) was first launched in Hesse in 2004. The project is supported by the health insurance companies in Hesse and the Professional Association of Gynaecologists in Hesse. The aim is to offer structured treatment programmes to all women diagnosed with breast cancer in Hesse by creating intersectoral cooperations between coordinating clinics, associated hospitals and gynaecologists in private practice who registered in the DMP programme. Method: Between 1 January 2005 and 30 June 2011, 13 973 women were enrolled in the DMP programme. Results: After data cleansing, survival rates were calculated for a total of 11 214 women. The 5-year overall survival (OS) rate was 86.3 %; survival rates according to tumour stage on presentation were 92.2 % (pT1) and 82.3 % (pT2), respectively. The impact of steroid hormone receptor status on survival (87.8 % for receptor-positive cancers vs. 78.9 % for receptor-negative cancers) and of age at first diagnosis on survival (≤ 35 years = 91 %) were calculated. Conclusion: The project showed that intersectoral cooperation led to significant improvements in the quality of treatment over time, as measured by quality indicators and outcomes after treatment.

    Purpose: Prostate stereotactic body radiotherapy (SBRT) may substantially recapitulate the dose distribution of high-dose-rate (HDR) brachytherapy, representing an externally delivered “Virtual HDR” treatment method. Herein, we present 5-year outcomes from a cohort of consecutively treated virtual HDR SBRT prostate cancer patients. Methods: Seventy-nine patients were treated from 2006 to 2009, 40 low-risk, and 39 intermediate-risk, under IRB-approved clinical trial, to 38 Gy in four fractions. The planning target volume (PTV) included prostate plus a 2-mm volume expansion in all directions, with selective use of a 5-mm prostate-to-PTV expansion and proximal seminal vesicle coverage in intermediate-risk patients, to better cover potential extraprostatic disease; rectal PTV margin reduced to zero in all cases. The prescription dose covered >95% of the PTV (V100 ≥95%), with a minimum 150% PTV dose escalation to create “HDR-like” PTV dose distribution. Results: Median pre-SBRT PSA level of 5.6 ng/mL decreased to 0.05 ng/mL 5 years out and 0.02 ng/mL 6 years out. At least one PSA bounce was seen in 55 patients (70%) but only 3 of them subsequently relapsed, biochemical-relapse-free survival was 100 and 92% for low-risk and intermediate-risk patients, respectively, by ASTRO definition (98 and 92% by Phoenix definition). Local relapse did not occur, distant metastasis-free survival was 100 and 95% by risk-group, and disease-specific survival was 100%. Acute and late grade 2 GU toxicity incidence was 10 and 9%, respectively; with 6% late grade 3 GU toxicity. Acute urinary retention did not occur. Acute and late grade 2 GI toxicity was 0 and 1%, respectively, with no grade 3 or higher toxicity. Of patient’s potent pre-SBRT, 65% remained so at 5 years. Conclusion: Virtual HDR prostate SBRT creates a very low PSA nadir, a high rate of 5-year disease-free survival and an acceptable toxicity incidence, with results closely resembling those reported

    Background We performed a literature-based analysis of randomized clinical trials to assess the pathologic complete response (pCR) (ypT0N0 after neoadjuvant therapy) and 3-year disease-free survival (DFS) as potential surrogate endpoints for 5-year overall survival (OS) in rectal cancer treated with neoadjuvant (chemo)radiotherapy (CT)RT. Methods A systematic literature search of PubMed, EMBASE, the Web of Science, SCOPUS, CINAHL, and the Cochrane Library was performed. Treatment effects on 3-year DFS and 5-year OS were expressed as rates of patients alive (%), and those on pCR as differences in pCR rates (∆pCR%). A weighted regression analysis was performed at individual- and trial-level to test the association between treatment effects on surrogate (∆pCR% and ∆3yDFS) and the main clinical outcome (∆5yOS). Results Twenty-two trials involving 10,050 patients, were included in the analysis. The individual level surrogacy showed that the pCR% and 3-year DFS were poorly correlated with 5-year OS (R=0.52; 95% CI, 0.31–0.91; P=0.002; and R=0.60; 95% CI, 0.36–1; P=0.002). The trial-level surrogacy analysis confirmed that the two treatment effects on surrogates (∆pCR% and ∆3yDFS) are not strong surrogates for treatment effects on 5-year OS % (R=0.2; 95% CI, −0.29–0.78; P=0.5 and R=0.64; 95% CI, 0.29–1; P=0.06). These findings were confirmed in neoadjuvant CTRT studies but not in phase III trials were 3-year DFS could still represent a valid surrogate. Conclusions This analysis does not support the use of pCR and 3-year DFS% as appropriate surrogate endpoints for 5-year OS% in patients with rectal cancer treated with neoadjuvant therapy.

    Survival studies of juvenile salmonids implanted with acoustic tags have been conducted at hydroelectric dams within the Federal Columbia River Power System (FCRPS) in the Columbia and Snake rivers between 2010 and 2014 to assess compliance with dam passage survival standards stipulated in the 2008 Biological Opinion (BiOp). For juvenile salmonids migrating downstream in the spring, dam passage survival defined as survival from the upstream dam face to the tailrace mixing zone must be ≥96% and for summer migrants, ≥93%, and estimated with a standard error ≤1.5% (i.e., 95% confidence interval of ±3%). A total of 29 compliance tests have been conducted at 6 of 8 FCRPS main-stem dams, using over 109,000 acoustic-tagged salmonid smolts. Of these 29 compliance studies, 23 met the survival standards and 26 met the precision requirements. Of the 6 dams evaluated to date, individual survival estimates range from 0.9597 to 0.9868 for yearling Chinook Salmon, 0.9534 to 0.9952 for steelhead, and 0.9076 to 0.9789 for subyearling Chinook Salmon. These investigations suggest the large capital investment over the last 20 years to improve juvenile salmon passage through the FCRPS dams has been beneficial.

    Cryptoendolithic microbial communities and epilithic lichens have been considered as appropriate candidates for the scenario of lithopanspermia, which proposes a natural interplanetary exchange of organisms by means of rocks that have been impact ejected from their planet of origin. So far, the hardiness of these terrestrial organisms in the severe and hostile conditions of space has not been tested over extended periods of time. A first long-term (1.5 years) exposure experiment in space was performed with a variety of rock-colonizing eukaryotic organisms at the International Space Station on board the European EXPOSE-E facility. Organisms were selected that are especially adapted to cope with the environmental extremes of their natural habitats. It was found that some-but not all-of those most robust microbial communities from extremely hostile regions on Earth are also partially resistant to the even more hostile environment of outer space, including high vacuum, temperature fluctuation, the full spectrum of extraterrestrial solar electromagnetic radiation, and cosmic ionizing radiation. Although the reported experimental period of 1.5 years in space is not comparable with the time spans of thousands or millions of years believed to be required for lithopanspermia, our data provide first evidence of the differential hardiness of cryptoendolithic communities in space.

    Vigabatrin (Sabril®), approved in the US in 2009, is currently indicated as adjunctive therapy for refractory complex partial seizures (rCPS) in patients ≥ 10 years old who have responded inadequately to several alternative treatments and as monotherapy for infantile spasms (IS) in patients 1 month to 2 years of age. Because of reports of vision loss following vigabatrin exposure, FDA approval required a risk evaluation mitigation strategy (REMS) program. Vigabatrin is only available in the US through Support, Help, And Resources for Epilepsy (SHARE), which includes a mandated registry. This article describes 5 years of demographic and treatment exposure data from adult patients (≥ 17 years old) in the US treated with vigabatrin and monitored in the ongoing Sabril® registry. Registry participation is mandatory for all US Sabril® prescribers and patients. A benefit-risk assessment must be documented by the physician for a patient to progress to maintenance therapy, defined as 1 month of vigabatrin treatment for patients with IS and 3 months for patients with rCPS. Ophthalmologic assessments must be documented during and after completion of therapy. As of August 26, 2014, a total of 6823 patients were enrolled in the registry, of which 1200 were adults at enrollment. Of these patients, 1031 (86%) were naïve to vigabatrin. The majority of adult patients (n=783, 65%) had previously been prescribed ≥ 4 AEDs, and 719 (60%) were receiving ≥ 3 concomitant AEDs at vigabatrin initiation. Prescribers submitted an initial ophthalmological assessment form for 863 patients; an ophthalmologic exam was not completed for 300 (35%) patients and thus, were considered exempted from vision testing. Of these patients, 128 (43%) were exempted for neurologic disabilities. Clinicians discontinued treatment in 8 patients because of visual field deficits (VFD) (5 patients naïve to vigabatrin and 3 patients previously exposed). Based on Kaplan-Meier survival estimates, it is

    Introduction: The Disease Management Project Breast Cancer (DMP Breast Cancer) was first launched in Hesse in 2004. The project is supported by the health insurance companies in Hesse and the Professional Association of Gynaecologists in Hesse. The aim is to offer structured treatment programmes to all women diagnosed with breast cancer in Hesse by creating intersectoral cooperations between coordinating clinics, associated hospitals and gynaecologists in private practice who registered in the DMP programme. Method: Between 1 January 2005 and 30 June 2011, 13 973 women were enrolled in the DMP programme. Results: After data cleansing, survival rates were calculated for a total of 11 214 women. The 5-year overall survival (OS) rate was 86.3 %; survival rates according to tumour stage on presentation were 92.2 % (pT1) and 82.3 % (pT2), respectively. The impact of steroid hormone receptor status on survival (87.8 % for receptor-positive cancers vs. 78.9 % for receptor-negative cancers) and of age at first diagnosis on survival (≤ 35 years = 91 %) were calculated. Conclusion: The project showed that intersectoral cooperation led to significant improvements in the quality of treatment over time, as measured by quality indicators and outcomes after treatment.

    This practice-based study evaluates the survival and success of conventionally luted metal-ceramic and zirconia molar crowns fabricated by using a prolonged cooling period for the veneering porcelain. Fifty-three patients were treated from 07/2008 to 07/2009 with either metal-ceramic crowns (MCC) or zirconia crowns (ZC). Forty-five patients (26 female) with 91 restorations (obser-vational period: 64.0 ± 4.8 months) participated in a clinical follow-up examination and were included in the study. Estimated cumulative survival (ECSv), success (ECSc) and veneering ceramic success (ECVCSc) were calculated (Kaplan-Meier) and analysed by the crown fabrication technique and the position of the restoration (Cox regression model) (P < 0.05). Five complete failures (MCC: 2, ZC: 3) were recorded (5-year ECSv: MCC: 97.6%, (95% confidence interval (95%-CI): [93%; 100%]/ZC: 94.0%, (95%-CI): [87%; 100%]). Of the MCCs (n = 41), 85.0%, [95%-CI: (77%; 96%)] remained event-free, whereas the ECSc for the ZCs (n = 50) was 74.3% (95%-CI): [61%; 87%]. No significant differences in ECSv (P = 0.51), ECSc (P = 0.43) and ECVCSc (P = 0.36) were detected between the two fabrication techniques. Restorations placed on terminal abutments (n = 44) demonstrated a significantly lower ECVCSc (P = 0.035), (5-year VCF-rate: 14.8%) than crowns placed on tooth-neighboured abutments (n = 47), (5-year VCF-rate: 4.3%). In the present study, zirconia molar crowns demonstrated a 5-year ECSv, ECSc and ECVCSc comparable to MCCs. Irrespective of the fabrication technique, crowns on terminal abutments bear a significantly increased risk for VCFs. Clinical investigations with an increased number of restorations are needed.

    The aim of this study was to assess among a population of women who had taken adjuvant tamoxifen for 5 years, how many were prepared to enter a randomised trial looking at the duration of tamoxifen treatment and what was the preference of those who declined trial entry. There is uncertainty as to the optimum duration of adjuvant tamoxifen and this is the subject of the aTTom (adjuvant Tamoxifen Treatment offer more?) trial in which patients are randomised to continue or stop tamoxifen after 5 years. Patients have been recruited to the aTTom trial in Dundee since 1996 and a record has been kept of all the patients with whom the trial was discussed. Patients who declined trial entry were allowed to choose whether to electively stop or continue tamoxifen. 306 patients were eligible for trial entry of whom 171 (56%) consented to randomisation (82 to continue and 89 to stop). Amongst the 135 (44%) who declined randomisation, 28 (21%) elected to stop tamoxifen treatment, 90 (67%) elected to continue and in 17 (13%) their decision was unclear. These results illustrate that patients eligible for the aTTom trial share our clinical equipoise. A majority (56%) of patients were agreeable to randomisation, but among those who declined, some (67%) preferred to continue, some (21%) to stop tamoxifen. This trial is unusual in that the patients have already experienced the treatment options, so the patients' preferences reflect a truly informed choice.

    2012-01-01

    Objective To estimate the prognosis over 5 years of HIV-1-infected, treatment-naive patients starting HAART, taking into account the immunological and virological response to therapy. Design A collaborative analysis of data from 12 cohorts in Europe and north America on 20 379 adults who started HAART between 1995 and 2003. Methods Parametric survival models were used to predict the cumulative incidence at 5 years of a new AIDS-defining event or death, and death alone, first from the start of HAART and second from 6 months after the start of HAART. Data were analysed by intention-to-continue-treatment, ignoring treatment changes and interruptions. Results During 61 798 person-years of follow-up, 1005 patients died and an additional 1303 developed AIDS. A total of 10 046 (49%) patients started HAART either with a CD4 cell count of less than 200 cells/μl or with a diagnosis of AIDS. The 5-year risk of AIDS or death (death alone) from the start of HAART ranged from 5.6 to 77% (1.8–65%), depending on age, CD4 cell count, HIV-1-RNA level, clinical stage, and history of injection drug use. From 6 months the corresponding figures were 4.1–99% for AIDS or death and 1.3–96% for death alone. Conclusion On the basis of data collected routinely in HIV care, prognostic models with high discriminatory power over 5 years were developed for patients starting HAART in industrialized countries. A risk calculator that produces estimates for progression rates at years 1 to 5 after starting HAART is available from www.art-cohort-collaboration.org. PMID:17502729

    Health experts advise and expect patients to eat healthily after bariatric surgery. For patients, difficulties with eating might have been a long-standing, problematic part of life-a part that is not necessarily healed by surgery. Empirical research on patients' experiences of eating practices after bariatric surgery is lacking. Aiming to contribute to the development of clinical practice, we explored meanings attached to eating in the long term and sought descriptions of change and bodily sensations. We interviewed 14 patients at least 5 years after bariatric surgery. The surgical restriction forced changes in the way patients sensed their own body in eating, but the uncertainty related to maintaining weight loss in the long term remained. Meanings attached to eating transcended food as choices situated in a nourishment and health perspective, and were not necessarily changed. Eating was an existential and embodied practice, which remained an ambiguous and sensitive matter after surgery.

    We present the results of a 5-year patient follow-up after implantation of an original neuroprosthesis. The system is able to stimulate both epimysial and neural electrodes in such a way that the complete flexor-extensor chain of the lower limb can be activated without using the withdrawal reflex. We demonstrate that standing and assisted walking are possible, and the results have remained stable for 5 years. Nevertheless, some problems were noted, particularly regarding the muscle response on the epimysial channels. Analysis of the electrical behaviour and thresholds indicated that the surgical phase is crucial because of the sensitivity of the functional responses to electrode placement. Neural stimulation proved to be more efficient and more stable over time. This mode requires less energy and provides more selective stimulation. This FES system can be improved to enable balanced standing and less fatiguing gait, but this will require feedback on event detection to trigger transitions between stimulation sequences, as well as feedback to the patient about the state of his lower limbs.

    This case report demonstrates the full-mouth rehabilitation of a 45-year-old male patient with severe deep-bite by increasing vertical dimension. The technique of anterior maxillary osteotomy performed in the present situation has been found to be effective, requiring anterior and inferior repositioning of the anterior maxilla to provide an esthetic and functional implant supported fixed prosthesis. Four months after surgery, the fixation system was removed, and 6 dental implants were placed. The anterior and inferior movements of the segment allowed for natural tooth anatomy and size in the definitive implant supported partial fixed prosthesis. A satisfactory functional and esthetic result was obtained after 5 years of follow-up. PMID:27403066

    I have performed total knee arthroplasty (TKA) using patient- specific instrumentation (PSI) (TRUMATCH® Personalized Solutions, DePuy Synthes Joint Reconstruction, Warsaw, Indiana) since July 2009. Since that time, I have performed over 600 of these procedures, all at the same hospital and all using the same personnel I worked with before I began using PSI. I do not have a physician assistant, but I do have a surgical assistant who scrubs with and assists me on all TKAs. There are a number of reasons why a surgeon may decide to use PSI. This paper discusses the effect PSI has had on my practice in the last 5 years, including my experiences and conclusions.

    Radiologically inserted gastrostomy (RIG) is an established way of maintaining enteral nutrition in patients who cannot maintain nutrition orally. The purpose of this study was to evaluate the safety and efficacy of primary placement of a wide bore button gastrostomy in a large, varied patient population through retrospective review. All patients who underwent gastrostomy placement from January 1, 2004 to January 1, 2009 were identified. 18-Fr gastrostomy buttons (MIC-Key G) were inserted in the majority. Follow-up ranged from 6 months to 4.5 years. A total of 260 patients (M:F 140:120, average age 59.2 years) underwent gastrostomy during the study period. Overall success rate for RIG placement was 99.6 %, with success rate of 95.3 % for primary button insertion. Indications included neurological disorders (70 %), esophageal/head and neck malignancy (21 %), and other indications (9 %). Major and minor complication rates were 1.2 and 12.8 %, respectively. Thirty-day mortality rate was 6.8 %. One third of patients underwent gastrostomy reinsertion during the study period, the main indication for which was inadvertent catheter removal. Patency rate was high at 99.5 %. The maximum number of procedures in any patient was 8 (n = 2), and the average tube dwell time was 125 days. Primary radiological insertion of a wide bore button gastrostomy is a safe technique, with high success rate, high patency rate, and low major complication rate. We believe that it is feasible to attempt button gastrostomy placement in all patients, once tract length is within limits of tube length. If difficulty is encountered, then a standard tube may simply be placed instead.

    Pompe disease is an autosomal recessive disease resulting from deficiency of the acid alpha-glucosidase (GAA). The late-onset Pompe Disease (LOPD) patients develop muscular and respiratory complications later in life. We describe a retrospective observational cohort study including 22 patients with LOPD. The cohort was assessed at baseline before Enzyme Replacement Therapy (ERT) with alglucosidase alpha (20mg/kg biweekly) was commenced and subsequently relevant information was collected at 2, 4 and 5years later. The median age of the patients at study entry was 44years (16-64years), with median disease duration of 11.5years (4-31years). At baseline, 10 patients (45%) could walk without support, 12 (55%) could walk with unilateral or bilateral support including 3/12 were wheelchair bound. Mean predicted FVC % was 55.7 (95% CI 45-66) of predicted normal at baseline and showed no significant change after 5years (54.6 (95% CI 43-66)), (all p=0.9815). Mean FVC % supine was 41.8 (95% CI 33.8-49) of predicted normal at baseline and remained significantly unchanged at 5years (48.4 (95% CI 37-59.6)), (all p=0.8680). The overnight non-invasive ventilator dependence increased by 18.2% as compared with baseline and requirement of mobility aids increased during this period by 5.2% as compared with the baseline. Mean walking distance at 6min walk test was 411.5 (95% CI 338-485) at baseline, 266.5 (95% CI 187-346) m at 2years, 238.6 (95% CI 162-315) m at 4years and 286.8 (95% CI 203-370) m at 5years (p=0.1981; ANOVA was completed only for 14 patients). A gradual decline in FVC% predicted was noted only in four cases and a decline in FVC% supine in two other. Only one patient showed a decline in both pulmonary function tests. In all remaining cases (17/22) respiratory function remains stable. In conclusion overall pulmonary function tests and mobility remained stable for 5years in majority of patients on ERT. However, in some patients they continued to decline in spite of ERT

    Objectives This study evaluates midterm survival rates and risk factors for mortality of chronic dialysis-dependent patients undergoing cardiac surgery. Methods Fifty-three dialysis-dependent patients (34 males, aged 67 ± 12 years) with end-stage renal disease operated within March 2007 and May 2012 were analyzed retrospectively. Survival rates were calculated using Kaplan-Meier methods. Predictors of midterm survival were identified with multivariate Cox-regression analysis. Results Twenty-three patients received isolated coronary artery bypass graft surgery, 17 received isolated valve replacement, and 13 received combined procedures. Thirty-day mortality was 24.5% (n = 13). Follow-up was complete for 94.3% (n = 50). Survival rates at 1, 3, and 5 years were: 82, 50, and 17%, respectively. Neither age, gender, poor ejection fraction, emergency, ECC/X-clamp (cross-clamp) time, nor use of left internal thoracic artery or right internal thoracic artery had any influence on midterm survival. Causes of death within midterm follow-up period were related to cardiac events in 16% and neurological events in 16%. In the majority (47%), cause of death was associated with peripheral arterial disease (PAD).The only comorbidity, which could be identified as a significant risk factor, was PAD (p = 0.035). Five patients underwent successful renal transplantation within the follow-up period. Conclusion Although 30-day mortality in this high-risk patient population was increased, midterm survival rates were comparable to the results described in the literature. Cause of death within midterm follow-up period was mostly noncardiac related. Given the limited number of patients, predictors for enhanced 30-day mortality, such as preoperative myocardial infarction, prolonged extracorporeal circulation, operation time, and diabetes mellitus, did not have an influence on midterm survival.

    Bariatric surgery provides sustainable weight loss and increased quality of life for most, but not all patients. To increase the knowledge of this complex patient group and their needs during follow-up, we aimed to describe the essential meaning of bariatric surgery patients' long-term experiences by using a phenomenological lifeworld approach. Eight patients were interviewed between 5 and 7 years after bariatric surgery. Life after bariatric surgery was described as living with tension, ambivalence, and reinforced attention toward one's own body. The tension was related to embodied change and altered relations to the social world. The patients express an ongoing demand for control of health-related habits and practices, and to not lose control over the body again. Surgical weight loss and improved physical function do not necessarily mean changed health-related habits and practices in the long term. Experiencing weight regain is connected with emotional stress, shame, and self-contempt.

    Recently, ultrasound-guided percutaneous renal biopsy has been used in the diagnosis of renal diseases. Development of an arteriovenous fistula (AVF), which is one of the post-biopsy complications, is not frequently encountered. AVFs are usually asymptomatic; however, they may lead to serious outcomes. We report a 21-year-old patient, who had been on dialysis for 5 years. Due to high blood pressure (230/160 mmHg) and a thrill in the lumbar area detected on physical examination, Doppler examination was performed and a renal AVF was detected. Because the patient had a history of renal biopsy 5 years previously, the fistula was thought to be secondary to the biopsy. After embolization of the AVF, renal functions improved enough to terminate dialysis treatment.

    Ifosfamide is indicated as first line treatment in a variety of solid tumours in adults. It is known to be nephrotoxic and is often used following therapy with, or as concomitant therapy with other potent nephrotoxins. To date, there are sparse case reports on the incidence of acute kidney injury (AKI) or chronic kidney disease (CKD) in adults exposed to ifosfamide. The available data on the long term renal complications for patients exposed to ifosfamide are thus based entirely on the paediatric population. The aim of this study was to assess the long term effects of ifosfamide exposure on renal function in an adult population and to determine if there are any treatment or patient specific factors that contribute to long term nephrotoxicity. The mean decline in estimated glomerular filtration rate (eGFR) following the first cycle of ifosfamide was 15 ml/min/1.73 m(2). Thereafter, there was a slower but steady decline in eGFR. No patient progressed to end stage renal disease (ESRD). Patient age and concomitant exposure to carboplatin were the only two factors which significantly affected eGFR. This represents the only long term study on the nephrotoxicity of ifosfamide in adults.

    Purpose: Accelerated partial breast irradiation (APBI) with balloon and catheter-based brachytherapy has gained increasing popularity in recent years and is the subject of ongoing phase III trials. Initial data suggest promising local control and cosmetic results in appropriately selected patients. Long-term data continue to evolve but are limited outside of the context of the American Society of Breast Surgeons Registry Trial. Methods and Materials: A retrospective review of 157 patients completing APBI after breast-conserving surgery and axillary staging via high-dose-rate {sup 192}Ir brachytherapy from June 2002 to December 2007 was made. APBI was delivered with a single-lumen MammoSite balloon-based applicator to a median dose of 34 Gy in 10 fractions over a 5-day period. Tumor coverage and critical organ dosimetry were retrospectively collected on the basis of computed tomography completed for conformance and symmetry. Results: At a median follow-up time of 5.5 years (range, 0-10.0 years), the 5-year and 7-year actuarial incidences of ipsilateral breast control were 98%/98%, of nodal control 99%/98%, and of distant control 99%/99%, respectively. The crude rate of ipsilateral breast recurrence was 2.5% (n=4); of nodal failure, 1.9% (n=3); and of distant failure, 0.6% (n=1). The 5-year and 7-year actuarial overall survival rates were 89%/86%, with breast cancer–specific survival of 100%/99%, respectively. Good to excellent cosmetic outcomes were achieved in 93.4% of patients. Telangiectasia developed in 27% of patients, with 1-year, 3-year, and 5-year actuarial incidence of 7%/24%/33%; skin dose >100% significantly predicted for the development of telangiectasia (50% vs 14%, P<.0001). Conclusions: Long-term single-institution outcomes suggest excellent tumor control, breast cosmesis, and minimal late toxicity. Skin toxicity is a function of skin dose, which may be ameliorated with dosimetric optimization afforded by newer multicatheter brachytherapy

    The aim of this study was to estimate the prevalence of total antibodies to hepatitis A virus (anti-HAV-T) in the group of HIV-positive adults in Lodz region of Poland, and to evaluate the response and long-term immunity after vaccination against hepatitis A virus. In the group of 234 HIV-infected patients, 72 persons (30.8%) were anti-HAV-T positive (>20 IU/L). In multivariate analysis, two independent factors associated with the presence of anti-HAV-T were identified: the age of patients (OR = 1.07) and the presence of antibodies to hepatitis C virus (OR = 2.87). Vaccination was completed in 83 patients. Good response (anti-HAV-T >20 IU/L one month after the booster dose) was obtained in 79.5% of patients. In patients with CD4 >200 cells/µL in multivariate analysis only presence of antibodies to hepatitis C virus was a prognostic factor for the response to vaccination (OR = 0.13). Among responders available for the follow-up, 82% (50 out of 61) had detectable anti-HAV-T at 1 year and 75.5% (37 out of 49) at 5 years. Our results demonstrate that most of the studied HIV-positive patients were susceptible to hepatitis A virus infection. Most HIV-infected adults with high CD4 counts had a durable response even up to 5 years after vaccination. Patients with a HIV/hepatitis C virus coinfection displayed a worse response to vaccination.

    A subcutaneous mass of the skull in children can have many different causes (infectious, tumoral, and inflammatory). We report on the case of a 5-year-old patient with a subcutaneous mass of the skull evolving over several months. The first pathological analysis concluded in Kimura disease. The progression and scarcity of this entity in children led to a second pathological analysis that showed lymphoblastic lymphoma B (LLB). This case reminds us that when there are discrepancies between pathological conclusions and clinical progression of a tumoral process, repeated analysis and immunochemistry are necessary.

    Several studies document the success of graduated driver licensing (GDL) systems in reducing young teen crash rates, but it is not yet clear whether any portion of the crash reduction is achieved by producing more capable drivers. The purpose of this study was to determine whether young teen drivers licensed under the North Carolina GDL system remain crash-free longer than those licensed prior to GDL, independent of the crude reductions in exposure (i.e., decreasing and delaying licensure) that may be responsible for most documented effects of GDL. Survival analysis was used to compare retrospective cohorts of 16-17 year olds before (n=105,569) and after (n=327,054) the North Carolina GDL system was implemented. The crash incidence of GDL-licensed 16-17 year olds (combined) was 10% lower than that for pre-GDL teens for at least 5 years after being licensed to drive independently (hazard ratio [HR]=0.90; 95% confidence interval [CI]=0.89, 0.91). However, more refined analysis revealed the reductions to only be among females (7%; HR=0.93; CI=0.91, 0.94) and males (15%; HR=0.85, CI=0.84, 0.87) licensed at age 16 and not among females (0%; HR=1.00; CI=0.95, 1.06) and males (0%; HR=1.00; CI=0.92, 1.09) licensed at age 17. Sixteen-year-old drivers licensed under the North Carolina GDL system experienced lower first-crash incidence during the first 5 years of unsupervised driving than did those licensed under the previous system. The benefits are greater for males, who tend to have higher crash rates. The findings contradict conventional wisdom that the entire benefit of GDL results merely from decreasing or delaying licensure among young drivers.

    In the 5-year follow-up period, we studied the quality of life of 145 patients who were at least 60 years old at the time of primary operation. Of the patients, 70 women had breast cancer and 75 endometrium cancer. We used the questionnaire "short form health survey: medical outcomes study". The areas which were analyzed were stress due to therapy, body image/femininity and social contacts. The Karnofsky-Index was determined by the physician. In both groups, most stress was felt due to the operation and at the first knowledge of the diagnosis. In the area of emotional stress 1/3 of the patients of both groups declared continuous stress due to feelings of fear, helplessness and passivity. In the area of body image/femininity half the patients with breast cancer and 2/3 with endometrial cancer felt stress. In the area of social contact 2/3 of the patients felt uncertainty in contact with others and this led to social retreat in 1/3 of the women. The Karnofsky-Index of all patients was between 50-100%. Our study supports the view that older patients with cancer should also be offered psychosocial counseling.

    Certain epidemiological and experimental studies suggest that n-3 fatty acids and folate can reduce blood pressure (BP). We investigated the effect of a daily supplementation with dietary doses of B-vitamins or n-3 fatty acids for 5 years on BP in patients with a history of CVD who participated in the Supplémentation en Folates et Omega-3 trial. The patients (n 2501; 1987 men and 514 women) were randomly assigned in a 2 × 2 factorial design to one of four groups: B-vitamins (5-methyl-THF (560 μg); vitamin B₆ (3 mg) and vitamin B₁₂ (20 μg)) and a placebo capsule for n-3 fatty acids; n-3 fatty acids (600 mg of EPA and DHA at a ratio of 2:1) and a placebo capsule for B-vitamins; both B-vitamins and n-3 fatty acids; or placebo capsules for both treatments. The patients took two capsules daily in a double-blind manner for a median duration of 4·7 years. At baseline and annual examination for 5 years, the patients underwent a clinical examination where BP and clinical and biological parameters were assessed. No effect of supplementation with either n-3 PUFA or B-vitamins on BP was observed in crude and adjusted multivariate models. Change in BP was not associated with change in homocysteine. In conclusion, the present results do not support the routine use of dietary supplements containing B-vitamins, or of n-3 fatty acids, to reduce BP in people with prior CVD.

    Despite the existence of standard protocol, many stabilization centers (SCs) continue to experience high mortality of children receiving treatment for severe acute malnutrition. Assessing treatment outcomes and identifying predictors may help to overcome this problem. Therefore, a 30-month retrospective cohort study was conducted among 545 randomly selected medical records of children <5 years of age admitted to SCs in Gedeo Zone. Data was entered by Epi Info version 7 and analyzed by STATA version 11. Cox proportional hazards model was built by forward stepwise procedure and compared by the likelihood ratio test and Harrell's concordance, and fitness was checked by Cox-Snell residual plot. During follow-up, 51 (9.3%) children had died, and 414 (76%) and 26 (4.8%) children had recovered and defaulted (missed follow-up for 2 consecutive days), respectively. The survival rates at the end of the first, second and third weeks were 95.3%, 90% and 85%, respectively, and the overall mean survival time was 79.6 days. Age <24 months (adjusted hazard ratio [AHR] =2.841, 95% confidence interval [CI] =1.101-7.329), altered pulse rate (AHR =3.926, 95% CI =1.579-9.763), altered temperature (AHR =7.173, 95% CI =3.05-16.867), shock (AHR =3.805, 95% CI =1.829-7.919), anemia (AHR =2.618, 95% CI =1.148-5.97), nasogastric tube feeding (AHR =3.181, 95% CI =1.18-8.575), hypoglycemia (AHR =2.74, 95% CI =1.279-5.87) and treatment at hospital stabilization center (AHR =4.772, 95% CI =1.638-13.9) were independent predictors of mortality. The treatment outcomes and incidence of death were in the acceptable ranges of national and international standards. Intervention to further reduce deaths has to focus on young children with comorbidities and altered general conditions.

    Metastasis to the incision site of squamous cervical cancer (SCC) is an extremely rare entity which is strictly related with extremely poor prognosis. The vast majority of the reported cases died in a year due to distant recurrences, whereby skin metastases were predominantly observed close to the primary tumor site. A SCC with skin metastasis which was diagnosed 5 years after the radical surgery and postoperative radiotherapy which involved the midline incision site was reported. Large surgical excision of the metastasis with remaining surgical free margins (>2 cm) and combined chemo-radiotherapy with single agent (cisplatinum) was performed. The patient did not show any recurrences for 4 years follow-up. Apparently, palliative combined chemo-radiotherapy along with large excision seems favorable for controlling symptoms and progression of skin metastasis of squamous cervical cancer.

    Adverse effects of long-term usage of triclosan-containing toothpaste in humans are currently unknown. We assessed the effect of long-term use of 0.3% triclosan-toothpaste on serious adverse events (SAEs) in patients with cardiovascular disease (CVD). 438 patients with a history of stable CVD were entered into the 5-year longitudinal Cardiovascular and Periodontal Study at Prince Charles Hospital, Brisbane, Australia and randomised into test (triclosan) or placebo groups. There were no significant differences in demographics or clinical features between the groups. Patients were examined at baseline, and annually for 5-years. SAEs were classified according to the System Organ Classes defined by MedDRA (Medical Dictionary for Regulatory Activities). Results were analysed using chi square and Kaplan Meier analysis. Overall, 232 patients (123 in the triclosan group; 109 in the placebo group) experienced 569 SAEs (288 in the triclosan group and 281 in the placebo group). There was no significant difference between the groups in numbers of patients experiencing SAEs (p=0.35) or specific cardiovascular SAEs (p=0.82), nor in time to the first SAE or first cardiovascular SAE, irrespective of gender, age or BMI after adjusting for multiple comparisons (p>0.05). The adjusted odds of experiencing an SAE were estimated to increase by 2.7% for each year of age (p=0.02) and the adjusted odds of experiencing a cardiovascular SAE were estimated to increase by 5.1% for each unit increase in BMI (p=0.02). Most cardiovascular events were related to unstable angina or myocardial infarcts, 21 were associated with arrhythmia and 41 were vascular events such as aortic aneurysm and cerebrovascular accident. Within the limitations of the present study the data suggest that the use of triclosan-toothpaste may not be associated with any increase in SAEs in this CVD population. The long-term impact of triclosan on hormone-related disease, such as cancer, in humans remains to be determined.

    Background The waiting time for deceased donor renal transplantation in the United States continues to grow. Retransplant candidates make up a small but growing percentage of the overall transplant waiting list and raise questions about the stewardship of scarce resources. The utility of renal transplantation among individuals with two prior renal transplants is not described in the literature and we thus sought to determine the survival benefit associated with a third kidney transplant (3KT). Methods Multivariable Cox regression models were created to determine characteristics associated with 3KT outcomes and the survival benefit of 3KT among recipients wait listed and transplanted within the United States between 1995 and 2009. Results 4,334 patients were waitlisted for a 3KT and 2,492 patients received a 3KT. In a multivariate analysis, 3KT demonstrated an overall patient survival benefit compared to the wait list (HR-0.379, CI=0.302-0.475 p<0.001) for those awaiting their first, second or third kidney transplants, although an inferior graft outcome compared to first kidney transplants. The time to survival benefit did not accrue until 8-months after transplant. Additionally we found that the duration of second graft survival was predictive of third graft survival, such that second graft survival beyond 5 years is associated with superior 3KT graft survival. Second graft loss in 30 days or less was not associated with inferior 3KT graft survival. Conclusion 3KT achieves a survival benefit over remaining on the wait list, although is associated with inferior graft outcomes compared to first kidney transplants. Graft survival of the second transplant beyond 5 years is associated with superior 3KT graft survival. PMID:25121473

    Purpose. To observe the effect of intravitreal ranibizumab injection on wet age-related macular degeneration (wAMD) over 5 years in Chinese patients. Methods. Thirty-seven patients who were diagnosed with wAMD in our hospital from June 2007 to June 2014 were retrospectively reviewed. The PRN regimen and the treatment and extend regimen were applied. Best corrected visual acuity (BCVA), number of ranibizumab injections, and changes in the choroidal neovascularization (CNV) lesion over 5 years were analyzed. Results. The mean BCVA measured by the ETDRS chart at baseline was 47.4 and 5 years after the treatment it was 34.89 letters, which was significantly different (p = 0.013). Fourteen eyes (37.8%) had improved visual acuity after 5 years. The number of injections in 5 years was 11.53, and most of the injections were in the first two years. Seventeen (45.9%) cases developed fibrous lesions, and 2 (5.4%) cases had atrophic lesions after 5 years. The fibrosis/atrophy was significantly correlated with the injection numbers (Pearson, r = 0.663, and p = 0.000). Conclusion. Most of the patients can maintain visual acuity treated by ranibizumab in the first 3 years. After 5 years, some patients can still improve or maintain visual acuity. Fibrous scarring of the lesion is the main reason for a decrease in vision of wAMD patients. PMID:27885338

    2013-01-01

    Background We assessed the influence of atorvastatin on selected indicators of an inflammatory condition, left ventricular function, hospitalizations and mortality in patients with dilated cardiomyopathy (DCM). Methods We included 68 DCM patients with left ventricular ejection fraction (LVEF) ≤40% treated optimally in a prospective, randomized study. They were observed for 5 years. Patients were divided into two groups: patients who were commenced on atorvastatin 40 mg daily for two months followed by an individually matched dose of 10 or 20 mg/day (group A), and patients who were treated according to current recommendations without statin therapy (group B). Results After 5-year follow-up we assessed 45 patients of mean age 59 ± 11 years - 22 patients in group A (77% male) and 23 patients in group B (82% male). Interleukin-6, tumor necrosis factor alpha, and uric acid concentrations were significantly lower in the statin group than in group B (14.96 ± 4.76 vs. 19.02 ± 3.94 pg/ml, p = 0.012; 19.10 ± 6.39 vs. 27.53 ± 7.39 pg/ml, p = 0.001, and 5.28 ± 0.48 vs. 6.53 ± 0.46 mg/dl, p = 0.001, respectively). In patients on statin therapy a reduction of N-terminal pro-brain natriuretic peptide concentration (from 1425.28 ± 1264.48 to 1098.01 ± 1483.86 pg/ml, p = 0.045), decrease in left ventricular diastolic (from 7.15 ± 0.90 to 6.67 ± 0.88 cm, p = 0.001) and systolic diameters (from 5.87 ± 0.92 to 5.17 ± 0.97, p = 0.001) in comparison to initial values were observed. We also showed the significant increase of LVEF in patients after statin therapy (from 32.0 ± 6.4 to 38.8 ± 8.8%, p = 0.016). Based on a comparison of curves using the log-rank test, the probability of survival to 5 years was significantly higher in patients receiving statins (p = 0.005). Conclusions Atorvastatin in a small dose significantly reduce levels of inflammatory cytokines and uric

    This follow-up extension of a randomised phase II study assessed differences in long-term outcomes between bortezomib-thalidomide-dexamethasone (VTD) and VTD-cyclophosphamide (VTDC) induction therapy in multiple myeloma. Newly diagnosed patients (n = 98) were randomised 1:1 to intravenous bortezomib (1·3 mg/m(2); days 1, 4, 8, 11), thalidomide (100 mg; days 1-21), and dexamethasone (40 mg; days 1-4, 9-12), with/without cyclophosphamide (400 mg/m(2); days 1, 8), for four 21-day cycles before stem-cell mobilisation/transplantation. After a median follow-up of 64·8 months, median time-to-next therapy was 51·8 and 47·9 months with VTD and VTDC, respectively. Type of subsequent therapy was similar in both arms. After adjusting for asymmetric censoring, median time to progression was not significantly different between VTD and VTDC [35·7 vs. 34·5 months; Hazard ratio (HR) 1·26, 95% confidence interval: 0·76-2·09; P = 0·370]. Five-year survival was 69·1% and 65·3% with VTD and VTDC, respectively. When analysed by minimal residual disease (MRD) status, overall survival was longer in MRD-negative versus MRD-positive patients with bone marrow-confirmed complete response (HR 3·66, P = 0·0318). VTD induction followed by transplantation provides long-term disease control and, consistent with the primary analysis, there is no additional benefit from adding cyclophosphamide. This study was registered at ClinicalTrials.gov (NCT00531453).

    Objective To identify early signs associated with poor prognosis in Chinese patients with systemic lupus erythematosus (SLE) through a large population-based follow-up study. Methods Medical records of > 2,500 SLE patients that first hospitalized between 1999–2009 were collected from 26 centers across Jiangsu province, China, and entered into a database. These patients were followed-up for 5 to 15 years, and those remained contact and had known survival status in 2015 were assessed for the association of factors presented at the initial hospitalization with mortality at two time points (≤1year and > 1year). The independency of mortality factors was evaluated using multivariate Cox regression analysis. Results Among 1,372 patients we assessed, 92.3% were women and 17.2% were deceased in 2015. The main causes of death were infection (30.1%), neuropsychiatric impairment (14.8%), renal failure (14.4%) and cardiopulmonary involvement (8.5%). Hazard ratios (HR) of independent predictors for mortality (≤1year and > 1year, respectively) included hospital presentation of neuropsychiatric involvement (2.03 and 1.91), cardiopulmonary involvement (1.94 and 1.61) and increased serum creatinine (2.52 and 2.58). Patients older than 45 years and with disease durations more than 2 years at admission had unfavorable short-term outcome (HR 1.76 and 1.79), while the presence of anti-dsDNA and anti-Sm antibodies indicated diverse prognosis after 1 year (HR 1.60 and 0.45). Treatment with cyclophosphamide was beneficial for patient’s first-year outcome (HR 0.50), and anti-malarial drugs significantly reduced the risk of mortality over different time points (HR 0.48 and 0.54). SLEDAI score, proteinuria or hypocomplementemia was not independently associated with the outcome in this cohort. Conclusion SLE patients presented with vital organ damages rather than active disease at initial hospitalization are likely to have a poor outcome, especially for those with neuropsychiatric

    AIM: To elucidate the clinicopathological characteristics and prognostic factors of gastric stump cancer (GSC). METHODS: The clinical data for 92 patients with GSC were collected at Fudan University Shanghai Cancer Center. The prognostic factors were analyzed with Cox proportional hazard models. RESULTS: GSC tended to occur within 25 years following the primary surgery, when the initial disease is benign, whereas it primarily occurred within the first 15 years post-operation for gastric cancer. Patients with regular follow-up after primary surgery had a better survival rate. The multivariate Cox regression analysis revealed that Borrmann type I/II (HR = 3.165, 95%CI: 1.055-9.500, P = 0.040) and radical resection (HR = 1.780, 95%CI: 1.061-2.987, P = 0.029) were independent prognostic factors for GSC. The overall 1-, 3-, and 5-year survival rates of the 92 patients were 78.3%, 45.6% and 27.6%, respectively. The 1-, 3-, and 5-year survival rates of those undergoing radical resection were 79.3%, 52.2%, and 37.8%, respectively. The 5-year survival rates for stages I, II, III, and IV were 85.7%, 47.4%, 16.0%, and 13.3%, respectively (P = 0.005). CONCLUSION: The appearance of GSC occurs sooner in patients with primary malignant cancer than in patients with a primary benign disease. Therefore, close follow-up is necessary. The overall survival of patients with GSC is poor, and curative resection can improve their prognosis. PMID:25684953

    Objective The rs12526453 (C/G) is a single nucleotide polymorphism in an intron of the PHACTR1 gene (phosphatase and actin regulator 1). The C allele is associated with increased risk of coronary artery disease in an unknown mechanism. We investigated its association with long-term overall mortality in patients with ST-elevation myocardial infarction (STEMI) treated invasively. Methods Two independent groups of patients with STEMI were analyzed: a derivation group (n= 638) and a validation one (n=348). Genotyping was performed with the TaqMan method. The analyzed end-point was total long term mortality. Additionally, transcriptomic analysis was performed in mononuclear blood leukocytes from rs12526453 CC monozygotes or G allele carriers. Results In the study group (mean age 62.3 ± 11.9 years; 24.9% of females, n=159), percentages of CC, CG, and GG genotypes were 45.3% (n=289), 44.7% (n=285), and 10% (n=64), respectively. In the 5-year follow-up 105 patients died (16.46%). CC homozygotes had significantly lower mortality compared to other genotypes: 13.1% (n=38) vs. 18.3% in G-allele carriers (n=67), (p=0.017, Cox`s F test). In the validation group 47 patients died within 3 years (13.5%). We confirmed lower mortality of CC homozygotes: 10.1 % (n=18) vs. 16.95% in G-allele carriers (n=29), (p=0.031, Cox`s F test). Transcriptomic analysis revealed a markedly higher expression of NLRP-2 in CC homozygotes. Conclusions The rs12526453 CC homozygotes (previously associated with increased risk of myocardial infarction) showed, in 2 independent samples, better long-term survival. The finding of such high effect size, after appropriate validation, could potentially be translated into clinical practice. PMID:26086777

    Lung cancer is the most common cause of cancer death with unchanged mortality for 50 years. Only localized nonsmall-cell lung cancer (NSCLC) is curable. In these patients it is essential to accurately predict survival to help identify those that will benefit from treatment and those at risk of relapse. Despite needing this clinical information, prospective data are lacking. We therefore prospectively identified prognostic factors in patients with potentially curable lung cancer. Over 2 years, 110 consecutive patients with confirmed localized NSCLC (stages 1-3A) were recruited from a single tertiary center. Prognostic factors investigated included age, gender, body mass index (BMI), performance status, comorbidity, disease stage, quality of life, and respiratory physiology. Patients were followed up for 3-5 years and mortality recorded. The data were analyzed using survival analysis methods. Twenty-eight patients died within 1 year, 15 patients died within 2 years, and 11 patients died within 3 years postsurgery. Kaplan-Meier survival estimates show a survival rate of 51% at 3 years. Factors significantly (p < 0.05) associated with poor overall survival were age at assessment, diabetes, serum albumin, peak VO(2) max, shuttle walk distance, and predicted postoperative transfer factor. In multiple-variable survival models, the strongest predictors of survival overall were diabetes and shuttle walk distance. The results show that potentially curable lung cancer patients should not be discriminated against with respect to weight and smoking history. Careful attention is required when managing patients with diabetes. Respiratory physiologic measurements were of limited value in predicting long-term survival after lung cancer surgery.

    Crown fracture of maxillary anterior teeth is relatively common among children and teenagers. Aesthetic rehabilitation of crown fractures of the maxillary anterior is one of the greatest challenges to the dentist. Reattachment of a fractured fragment to the remaining tooth can provide better and long-lasting aesthetics, improved function, a positive psychological response and is a faster and less-complicated procedure. This article presents a case of reattachment of anterior tooth with a coronal fracture involving enamel, dentin and pulp with a 1.5-year follow-up.

    Junctional epidermolysis bullosa (JEB) is a particularly devastating type of epidermolysis bullosa, especially in the newborn period. Data about the number of new cases of JEB in the United States were collected from the records of the Dystrophic Epidermolysis Bullosa Research Association of America (DebRA) nurse educator. Seventy-one children with JEB were reported to have been born in the 5 years between 2007 and 2011, reflecting an incidence of at least 3.59 per million per year, significantly higher than previously estimated (2.04 per million). There was a high prevalence of morbidity and infant mortality of at least 73%, as 52 of the 71 cases proved fatal by June 2012. These data emphasize the need for future research to develop treatment and ultimately a cure for this disorder.

    Purpose. To report 5-year contrast-enhanced magnetic resonance imaging findings of the REST trial recruits who underwent either uterine artery embolization (UAE) or myomectomy. Methods. A total of 157 patients were randomized to UAE or surgery (hysterectomy or myomectomy). Ninety-nine patients who had UAE and eight patients who had myomectomy were analyzed. MRI scans at baseline, 6 months, and 5 years were independently interpreted by two radiologists. Dominant fibroid diameter, uterine volume, total fibroid infarction (complete 100 %, almost complete 90-99 %, partial <90 %), and new fibroid formation were the main parameters assessed and related to the need for reintervention. Results. In the UAE group, mean {+-} standard deviation uterine volume was 670 {+-} 503, 422 {+-} 353, and 292 {+-} 287 mL at baseline, 6 months, and 5 years, respectively. Mean dominant fibroid diameter was 7.6 {+-} 3.0, 5.8 {+-} 2.9, and 5 {+-} 2.9 cm at baseline, 6 months, and 5 years. Fibroid infarction at 6 months was complete in 35 % of women, almost complete in 29 %, and partial in 36 %. Need for reintervention was 19, 10, and 33 % in these groups, respectively (p = 0.123). No myomectomy cases had further intervention. At 5 years, the prevalence of new fibroid was 60 % in the myomectomy group and 7 % in the UAE group (p = 0.008). Conclusion. There is a further significant reduction in both uterine volume and dominant fibroid diameter between 6 months and 5 years after UAE. Complete fibroid infarction does not translate into total freedom from a subsequent reintervention. New fibroid formation is significantly higher after myomectomy.

    Purpose To evaluate the effect of serum alpha-fetoprotein(AFP) on prognosis of patients with hepatocellular carcinoma (HCC) and put forward a proposal to modify BCLC staging system and the recommended treatment of patients with stage C. Results AFP positive was an independent poor prognostic factor of HCC. Race, pathological grade, T stage, M stage were also regarded to be significant predicted factors for poorer prognosis. When combining AFP status with AJCC stage, patients with A1 disease had a worse prognosis compared with those with A0 disease within each stage. Patients with A1 disease of each T/N stage had a worse prognosis than patients with A0 disease of the respective stage, and the prognosis of patients with A1 disease with lower T stages was worse or similar to that of patients with A0 disease of higher T stages. Materials and Methods We performed a retrospective study of all patients histologically diagnosed HCC from January 1, 2004, through December 31, 2008, from the SEER database. Conclusions AFP can be used as a subclassification index to modify the AJCC staging system of HCC. Since BCLC stage is the most widely used staging system, we recommend routine pre-treatment AFP testing as standard of care in HCC and incorporate AFP status into the BCLC staging system to modify the recommended treatment of patients with stage C.

    To determine whether 2 readily available indicators predicted survival among patients with Ebola virus disease in Sierra Leone, we evaluated information for 216 of the 227 patients in Bo District during a 4-month period. The indicators were time from symptom onset to healthcare facility admission and quantitative real-time reverse transcription PCR cycle threshold (Ct), a surrogate for viral load, in first Ebola virus-positive blood sample tested. Of these patients, 151 were alive when detected and had reported healthcare facility admission dates and Ct values available. Time from symptom onset to healthcare facility admission was not associated with survival, but viral load in the first Ebola virus-positive blood sample was inversely associated with survival: 52 (87%) of 60 patients with a Ct of >24 survived and 20 (22%) of 91 with a Ct of <24 survived. Ct values may be useful for clinicians making treatment decisions or managing patient or family expectations.

    The survival of younger patients with acute leukemia has improved in the early 21(st) century, but it is unknown whether people of all ethnic and racial backgrounds have benefited equally. Using cancer registry data from the Surveillance, Epidemiology and End Results Program, we assessed trends in 5-year relative survival for patients aged 15 years or more with acute lymphoblastic leukemia and acute myeloblastic leukemia divided by racial and ethnic group, including non-Hispanic whites, African-Americans, Hispanics, and Asian-Pacific Islanders in the 1990s and the early 21(st) century. Modeled period analysis was used to obtain the most up-to-date estimates of survival. Overall, the 5-year survival increased from 31.6% in 1997-2002 to 39.0% in 2003-2008 for patients with acute lymphoblastic leukemia and from 15.5% in 1991-1996 to 22.5% in 2003-2008 for those with acute myeloblastic leukemia. Nevertheless, among patients with acute lymphoblastic leukemia, age-adjusted 5-year relative survival rates remained lower for African-Americans and Hispanics than for non-Hispanic whites. Among patients with acute myeloblastic leukemia, the increase in survival was greatest (from 32.6% in 1991-1996 to 47.1% in 2003-2008) for younger patients (15-54 years), and was more pronounced for non-Hispanic whites (+16.4% units) than for other patients (+10.8% units). Increases in survival are observed in all ethnic or racial groups. Nevertheless, among patients with acute leukemias, disparities in survival persist between non-Hispanic white people and people of other ethnic or racial groups. Disparities are increasing in younger patients with acute myeloblastic leukemia. Improvements in access to treatment, especially for minority patients, may improve outcomes.

    To assess the sequence and type of active joints in a cohort of newly diagnosed juvenile idiopathic arthritis (JIA) patients with full access to current treatment at first visit and during a follow-up period of 5-years, in order to identify an index joint/group of joints for magnetic resonance imaging in JIA. Patient charts of all consecutive newly diagnosed JIA patients with a follow-up duration of at least 5 years were analyzed. Patients were derived from two tertiary pediatric rheumatology centers. Patient characteristics and data concerning the presence of joints with arthritis and the use of medication were recorded. Findings from 95 JIA patients [39 (41 %) oligoarticular and 56 (59 %) polyarticular] were analyzed. At first visit, distribution of active joints among patients was as follows: knee (n = 70, 74 %), ankle (n = 55, 58 %), elbow (n = 23, 24 %), wrist (n = 23, 24 %), metacarpophalangeal (MCP) (n = 20, 21 %), proximal interphalangeal (PIP) (n = 13, 14 %), hip (n = 6, 6 %), shoulder (n = 5, 5 %), and distal interphalangeal (DIP) (n = 4, 4 %) joints. After a follow-up period of 5 years, the cumulative percentage of patients with specific joint involvement changed into: knee (n = 88, 93 %), ankle (n = 79, 83 %), elbow (n = 43, 45 %), wrist (n = 38, 40 %), MCP (n = 36, 38 %), PIP (n = 29, 31 %), shoulder (n = 20, 21 %), hip (n = 17, 19 %), and DIP (n = 9, 10 %) joints. Despite changes in treatment strategies over the years, the knee remains the most commonly involved joint at onset and during follow-up in JIA, followed by the ankle, elbow, and wrist. For the evaluation of outcome with MRI, the knee appears the most appropriate joint in JIA.

    This paper for the first time presents Austrian data on survival of patients, diagnosed from 1998 through 2002, with colon cancer and with rectal cancer. Cumulative relative survival rates were calculated by age, standardized for all ages and stages combined, and by age groups (< 50 years, 50-64 years, and =65 years) according to stages (localized, regional metastases and distant metastases). In carcinoma of the colon 5-year relative survival was 66 % in males and 64 % in females. In carcinoma of the rectum 5-year relative survival was 64 % in males and 67 % in females. Compared to the earlier results from the Tyrol (based on patients diagnosed from 1990 through 1994) the 5-year survival of patients with colon cancer increased from 55 % to 66 % in males and from 58 % to 64 % in females. In patients with rectal cancer 5-year survival increased from 44 % to 64 % in males and from 46 % to 67 % in females. This increase in part can be explained by a positive effect of early detection and of better treatment.

    Condylar fractures in children are especially important because of the risk of a mandibular growth-center being affected in the condylar head, which can lead to growth retardation and facial asymmetry. The purpose of this article is to follow up the two and half year clinical and radiological evaluation of the conservative treatment of a 10 year-old patient, who had a unilateral green-stick type fracture. The patient presented with painful facial swelling localized over the left condylar region, limited mouth-opening and mandibular deviation to the left. Panoramic radiography and computed tomography confirmed the diagnosis of incomplete fracture on the left condyle with one side of the bone fractured and the other bent. Closed reduction was chosen to allow for initial fibrous union of the fracture segments and remodeling with a normal functional stimulus. A non-rigid mandibular splint was applied in order to remove the direct pressure on the fracture side of the mandible. Clinical and radiologic examination after 30 months revealed uneventful healing with reduction of the condylar head and remodeling of the condylar process following conservative treatment.

    Objective To assess the effects of subcutaneous (sc) interferon (IFN) -1a on cognition over 5 years in mildly disabled patients with relapsing–remitting multiple sclerosis (RRMS). Methods Patients aged 18–50 years with RRMS (Expanded Disability Status Scale score ≤4.0) who had completed the 3-year COGIMUS study underwent standardized magnetic resonance imaging, neurological examination, and neuropsychological testing at years 4 and 5. Predictors of cognitive impairment at year 5 were identified using multivariate analysis. Results Of 331 patients who completed the 3-year COGIMUS study, 265 participated in the 2-year extension study, 201 of whom (75.8%; sc IFN β-1a three times weekly: 44 µg, n = 108; 22 µg, n = 93) completed 5 years' follow-up. The proportion of patients with cognitive impairment in the study population overall remained stable between baseline (18.0%) and year 5 (22.6%). The proportion of patients with cognitive impairment also remained stable in both treatment groups between baseline and year 5, and between year 3 and year 5. However, a significantly higher proportion of men than women had cognitive impairment at year 5 (26.5% vs 14.4%, p = 0.046). Treatment with the 22 versus 44 µg dose was predictive of cognitive impairment at year 5 (hazard ratio 0.68; 95% confidence interval 0.48–0.97). Conclusions This study suggests that sc IFN β-1a dose-dependently stabilizes or delays cognitive impairment over a 5-year period in most patients with mild RRMS. Women seem to be more protected against developing cognitive impairment, which may indicate greater response to therapy or the inherently better prognosis associated with female sex in MS.

    Background Psychiatric emergencies of children and adolescents have greatly increased during the last years, but this phenomenon has not been studied in detail. The aim of this study was to analyze the correlation between acute psychiatric hospitalizations of adolescents and selected variables to highlight risk factors for psychiatric emergencies. Methods This retrospective research was conducted in the acute psychiatric public ward, Service of Psychiatric Diagnosis and Treatment (SPDT), and in the residential facility for adolescents, “The Medlar”, located in Modena. The sample was constituted by all adolescent patients (n=101, age range 14–18) who had acute hospitalizations (n=140) in SPDT and had been successively transferred to “The Medlar” (n=83), from February 2, 2010 to January 31, 2015. From clinical charts, we extracted demographic and anamnestic characteristics of patients and clinical variables related to hospitalizations. Data were statistically analyzed. Results Sixty-one percent of our patients lived with one divorced parent, with adoptive or immigrant family, or in institutions; 51% had experienced stressful events during childhood; 81% had a normal intellective level, but only 6% presented regular school performance. Parental psychiatric illness was negatively related, in a statistically significantly way, with onset age of adolescent mental disorders (coefficient −2.28, 95% confidence interval [CI]: −3.53 to 1.01, P<0.001, single linear regression; odds ratio: 4.39, 95% CI: 1.43–13.47, P<0.010, single logistic regression). The most frequent reasons for admission were aggressive behavior in males and suicide risk in females (P=0.002). The most frequent psychiatric diagnosis at SPDT discharge was “conduct disorder”, more frequent in males, followed by “adjustment disorder”, more frequent in females (P=0.001). In SPDT, the adolescent hospitalizations progressively increased fivefold at the end of the observation period

    Background There is conflicting data in contemporary literature concerning the best way to treat patients with stable coronary artery disease; specifically, whether medical treatment alone or invasive strategies combined with medical treatment are better. The purpose of this study was to evaluate the clinical outcomes of patients with and without revascularization after stress echocardiography and to create formulas for detecting patients with a very high risk of cardiac death/major adverse cardiac event (MACE) in their present conditions. Methods We assessed 323 patients (53.9 ± 8.4 years, 247 men), undergoing upright bicycle stress echocardiography in 2006 - 2007. During a median follow-up of 5.2 ± 0.2 years, 21 cardiovascular and 5 confirmed non-cardiac deaths occurred. Eighty-three patients underwent revascularization. Results Stress echocardiography was normal in 32% and abnormal in 68%. All the patients with CAD were prescribed acetylsalicylic acid, statins, beta-blockers and ACE inhibitors. Eighty-seven percents of the patients took medication regularly. The percentage taking medication didn’t significantly differ in the subgroups. Two formulas were created for detecting a very high risk of cardiac death (25%) or MACE (68%) within 5 years. All the patients with abnormal stress tests were divided into two subgroups: 80 patients with revascularization and 138 subjects without revascularization. There was a significant difference in 5 year cardiac mortality if the patients had an index of wall motion abnormality (IWMA) after exercise greater than or equal to 1.3. Conclusion It is possible to identify during stress echocardiography subjects with a very high risk for cardiac death/MACE. Patients with IWMA ≥ 1.3 had improved outcomes following revascularization.

    In the period between april 1984 and march 1989, 246 newborn children with transposition of the great vessels benefited from anatomical repair of their heart disease. 221 children had simple transposition with normal interventricular septa. These were aged 2 to 23 days (mean age 7.8 +/- 3.5 standard deviation). 25 had transposition of the great vessels associated with a large interventricular septum defect. These were aged 7 to 30 days (mean age 18 +/- 8.3 S.D.). Associated lesions included a small interventricular septum defect in 20 cases which was not treated at the time of the operation; tricuspid insufficiency in 3 cases; and isthmic coarctation of the aorta in 10 cases. According to Yacoub's classification relative to the anatomical distribution of the coronary arteries, all the children fell into the following groups: type A, 172 cases; type B, 8 cases; type C, 12 cases; type D, 40 cases; type E, 14 cases. Preoperative catheterization was carried out in all the children. 96% benefited from Rashkin's atrioseptostomy, 90% had a prostaglandin infusion continuing through surgery. The surgical technique included the use of continuous extracorporal circulation at 20 degrees C, without circulatory arrest. Protection of the myocardium was ensured during aortic clamping by injecting of a crystalloid cardioplegia-inducing solution. The main steps of surgical repair were repositioning of the coronary arteries onto the ancient aortic stump and reconstruction of a pulmonary shunt. Repositioning of the coronary arteries was carried out in accordance with Yacoub's technique in all cases except for the 10 first patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective: To analyze the efficacy and safety of entecavir (ETV) treatment for up to 5 years in nucleos(t)ide-naïve chronic hepatitis B patients in real life. Methods: We retrospectively analyzed 230 nucleos(t)ide naïve chronic hepatitis B patients who received ETV 0.5 mg/day monotherapy for at least 3 months, of whom 113 were HBeAg positive and 117 were HBeAg negative. The primary endpoints was cumulative probability of achieving a virological response (undetectable serum HBV DNA, <100IU/mL). Secondary endpoints were rates of ALT normalization (ALT < upper limit of normal), HBeAg seroconversion, resistance, and safety. Results: The median follow-up duration was 27.5 months (3-73 months) and mean age was 42 years. With 230, 214, 180, 142, 88, 42 and 11 patients followed-up for at least 3 months,6 months, 1, 2, 3, 4 and 5 years, respectively. In all, Incremental increases were observed in the rates of undetectable HBV DNA. 67.0%, 85.0%, 89.4%, 94.4%, 95.5%, 97.6%, 100% had undetectable HBV DNA at month 3, month 6, 1 year, 2 years, 3 years, 4 years and 5 years. Proportions of patients achieving normal ALT were 73.9%, 85.5%, 82.8%, 89.4%, 80.7%, 85.7%, 100%, respectively. The rate of HBeAg seroconversion reached 21.4% and 15.4% at year2, 3, respectively. One patient achieved HBsAg seroclearance after 1 year, and achieved anti-HBs seroconversion at year 3. Of 180 patients, HBV DNA was detectable (partial virological response, PVR) in 19 patients at year 1 of follow-up, twelve of 14 (85.7%) patients with PVR need more than 1 year of continuous ETV therapy to achieved VR. At baseline, no ETV-resistance was detected in 25 ETV-naïve patients. One patient developed ETV-resistance mutations due to noncompliance. No serious adverse event was reported. Conclusion: Long-term ETV treatment of nucleos(t)ide-naïve was effective and safe in real life. Adjustment of ETV monotherapy in nucleos(t)ide-naïve patients with a partial virological response at 1 year may be unnecessary

    Data from 519 patients older than 65 years with congestive heart failure (CHF) were analyzed after 5 years of clinical follow-up. Two groups were included in the analysis: 321 patients with ejection fractions > or =50% (group with diastolic heart failure) and 198 patients with reduced ejection fraction <50% (group with systolic heart failure). Hypertension (81%) was the strongest predictor of congestive heart failure, followed by diabetes (46%) and coronary disease (33%). Diastolic heart failure was more predominant in elderly female (P=.007), hypertensive (P=.0001), and hypertrophic (P=.001) patients. Length of hospital stay, readmission rate, all-cause morbidity, and cumulative mortality were not statistically significant between both groups (P=.09).

    Molluscum contagiosum virus (MCV) is a common skin pathogen in both adults and children. In this prospective study, we clinically evaluated consecutive patients with molluscum contagiosum (MC) who had been examined during a 5-year period at the second-largest dermatology clinic in Slovenia and described their main demographic and clinical characteristics, concomitant diseases, and treatment success. The study included 188 patients, of which 121 (64%) were men and 67 (36%) were women. A total of 135 (72%) patients were adults, with lesions that were most commonly located in the anogenital region (98%) and were probably sexually acquired. Two adult patients were diagnosed with concurrent human immunodeficiency virus (HIV) infection. Fifty-three (28%) patients were children with a mean age of 5.7 years, most commonly presenting with lesions on the torso and extremities (85%). In adults, the infection most commonly occurred in male patients, while in children it was slightly more common in female patients. At presentation, 58% of patients had more than 5 MC lesions. A total of 30% of the included children had concomitant atopic dermatitis. We did not observe an increased occurrence of MCV infection in patients with atopic dermatitis. All patients were treated with curettage of the lesions. The cure rate at the first follow-up visit after 2 months was relatively high (63%), and recurrences were not associated with the number or site of lesions at presentation or with concomitant atopic dermatitis.

    Background Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long-term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. Methods and Results The CREDO-Kyoto AMI Registry is a large-scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005–2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary PCI. Clinical outcomes were compared between the 2 patient groups with or without TA. During primary PCI procedures, 2239 out of 3536 (63%) patients underwent TA (TA group). The cumulative 5-year incidence of all-cause death was significantly lower in the TA group than in the non-TA group (18.5% versus 23.9%, log-rank P<0.001). After adjusting for confounders, however, the risk for all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio: 0.90, 95% CI: 0.76 to 1.06, P=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target-lesion revascularization were also not significantly different between the 2 groups. Conclusions Adjunctive TA during primary PCI was not associated with better 5-year mortality in STEMI patients. PMID:26077588

    Background: To compare the incidence and timing of bone fractures in postmenopausal women treated with 5 years of adjuvant tamoxifen or letrozole for endocrine-responsive early breast cancer in the Breast International Group (BIG) 1-98 trial. Methods: We evaluated 4895 patients allocated to 5 years of letrozole or tamoxifen in the BIG 1-98 trial who received at least some study medication (median follow-up 60.3 months). Bone fracture information (grade, cause, site) was collected every 6 months during trial treatment. Results: The incidence of bone fractures was higher among patients treated with letrozole [228 of 2448 women (9.3%)] versus tamoxifen [160 of 2447 women (6.5%)]. The wrist was the most common site of fracture in both treatment groups. Statistically significant risk factors for bone fractures during treatment included age, smoking history, osteoporosis at baseline, previous bone fracture, and previous hormone replacement therapy. Conclusions: Consistent with other trials comparing aromatase inhibitors to tamoxifen, letrozole was associated with an increase in bone fractures. Benefits of superior disease control associated with letrozole and lower incidence of fracture with tamoxifen should be considered with the risk profile for individual patients. PMID:19474112

  1. Changes in the management and survival rates of patients with oral cancer: a 30-year single-institution study

    2016-01-01

    Objectives The aim of the present study was to evaluate changes in the management and 5-year survival rates of patients with oral cancer in our department over a 30-year period. Materials and Methods We investigated the patient distributions, treatment methods, method of neck dissection according to cancer stage, and 5-year survival rates for 700 oral cancer patients over the periods of 1982–1996 (256 patients), 1999–2006 (248 patients), and 2007–2011 (196 patients). Results Stage IV patients were the largest group in all of the time periods evaluated. Although surgery and radiotherapy were the most common methods in all periods (over 50%), the prevalence of patients who underwent concomitant chemoradiotherapy increased from 7.0% to 16.2%. The use of radical neck dissection decreased from 43.0% to 5.3%, while conservative surgical methods increased from 24.1% to 76.3%. Lastly, the overall 5-year survival rate increased from 31.6% to 63.5% during the study period. Conclusion Although the 5-year survival rate reached the same level as that of other developed countries during the course of our study, most patients continue to come to the hospital with stage IV disease. In order to increase the 5-year survival rate of oral carcinoma, it may be necessary to improve public education and social efforts relevant to early diagnosis. PMID:26904492

    Conditional disease-free survival (CDFS) reflects changes over time. Because traditional disease-free survival (DFS) is estimated from the date of diagnosis, it is limited in the ability to predict risk of recurrence in patients who have been disease free. In this study, we determined CDFS of breast cancer patients and estimated the prognostic factors for DFS.We retrospectively reviewed clinical data of 7587 consecutive patients who underwent curative surgery for breast cancer between January 2004 and December 2013 at Samsung Medical Center. Univariate and multivariate analyses were performed to identify risk factors for DFS, which was computed using the Kaplan-Meier method. CDFS rates were based on cumulative DFS estimates.Median follow-up duration was 20.59 months. Three-year DFS was 93.46% at baseline. Three-year CDFS survival estimates for patients who had been disease free for 1, 2, 3, 4, and 5 years after treatment were calculated as 92.84%, 92.37%, 93.03%, 89.41%, and 79.64%, respectively. Three-year CDFS increased continuously each year after 1 year of DFS in hormone receptor (HR)-negative patients but decreased each year in HR-positive patients.In HR-positive patients who are disease free after 3 years, continuous care including surveillance and metastases workup should be considered, although this is not recommended in the current guidelines. On the other hand, the social costs may be reduced in HR-negative patients by extending the surveillance interval. Further studies are needed to identify indicators of DFS prognosis in breast cancer patients.

    Background Diabetic kidney disease is the leading cause of stage 5 chronic kidney disease (CKD) in India. Renal replacement therapy (RRT) is accessible to very few patients because of socioeconomic deprivation. We studied the effect of diabetes and socioeconomic status on the outcome of patients on maintenance hemodialysis (MHD). Methods We retrospectively analyzed the outcome of 897 patients (629 males/268 females; mean age ± standard deviation 48.69 ± 14.27 years) initiated on MHD from 2003 to 2009 at five dialysis centers in south India. There were 335 type 2 diabetic patients and 562 non-diabetic patients. Group 1 comprised the self-paying patients (518 patients) and Group 2 included the TANKER Foundation charity dialysis patients (379 patients). We compared the 5-year survival rates of Group 1 versus Group 2 and also those of diabetic versus non-diabetic patients, using the Kaplan–Meier survival estimator. Results Of the 897 patients, 166 patients survived, 350 died, 234 were lost to follow-up, 137 had renal transplantation and 10 patients were transferred to peritoneal dialysis. The 5-year survival rates after censoring were 20.7 and 38.2% for diabetic and non-diabetic patients, respectively (P < 0.001). The survival rate of diabetic patients was significantly lower, compared with non-diabetic patients, in Group 2 (P < 0.001), but not significantly lower in Group 1 (P = 0.226). Conclusions Diabetic patients have poor survival rates on MHD, especially those from poor socioeconomic groups. Due to scarce RRT facilities and poor survival rates of diabetic patients, prevention, early detection and management of diabetic CKD patients should be the way to go forward. PMID:27994864

    Surgical procedures for atlantoaxial (C1–C2) fusion in young children are relatively uncommon. The purpose of this study was to report on a surgical treatment for a case of atlantoaxial instability caused by os-odontoideum in association with quadriparesis and respiratory paralysis in a 5-year-old girl. We present the patient's history, physical examination, and radiographic findings, describe the surgical treatment and a five year follow-up, and provide a literature review. The instability was treated by halo immobilization, followed by C1–C2 transarticular screw fixation using a computed tomography-based navigation system. At the five year follow-up, the patient had made a complete recovery with solid union. The authors conclude that C1–2 transarticular screw fixation is technically possible as in a case of atlantoaxial instability in a five-year-old child. PMID:27790327

    2013-01-01

    Background Few data exist on viral and bacterial etiology of acute lower respiratory infections (ALRI) in ≥5 year –old persons in the tropics. Methods We conducted active surveillance of community-acquired ALRI in two hospitals in Cambodia, a low-income tropical country. Patients were tested for acid-fast bacilli (AFB) by direct sputum examination, other bacteria by blood and/or sputum cultures, and respiratory viruses using molecular techniques on nasopharyngeal/throat swabs. Pulmonologists reviewed clinical/laboratory data and interpreted chest X-rays (CXR) to confirm ALRI. Results Between April 2007 - December 2009, 1,904 patients aged ≥5 years were admitted with acute pneumonia (50.4%), lung sequelae-associated ALRI (24.3%), isolated pleural effusions (8.9%) or normal CXR-related ALRI (17.1%); 61 (3.2%) died during hospitalization. The two former diagnoses were predominantly due to bacterial etiologies while viral detection was more frequent in the two latter diagnoses. AFB-positive accounted for 25.6% of acute pneumonia. Of the positive cultures (16.8%), abscess-prone Gram-negative bacteria (39.6%) and Haemophilus influenzae (38.0%) were most frequent, followed by Streptococcus pneumoniae (17.7%). Of the identified viruses, the three most common viruses included rhinoviruses (49.5%), respiratory syncytial virus (17.7%) and influenza viruses (12.1%) regardless of the diagnostic groups. Wheezing was associated with viral identification (31.9% vs. 13.8%, p < 0.001) independent of age and time-to-admission. Conclusions High frequency of H. influenzae and S. pneumoniae infections support the need for introduction of the respective vaccines in the national immunization program. Tuberculosis was frequent in patients with acute pneumonia, requiring further investigation. The relationship between respiratory viruses and wheezing merits further studies. PMID:23432906

    Existing research into learning about patient safety focuses on identifying how educational interventions improve educational outcomes but few studies offer evidence that inform educators about the mechanisms involved in learning about patient safety. The current evidence based in undergraduates is also limited to outcomes that relate to knowledge and skills. A realist approach involving three cycles of data collection in a single cohort of students over 5 years used different outcomes in Kirkpatrick's framework to identify the mechanisms that influence students learning about patient safety. Data source 1. Focus groups identified an overarching theoretical model of the mechanisms that influence patient safety learning for medical students. Data source 2 Identified if the mechanisms from data source 1 could be demonstrated at the outcome level of knowledge and attitudes. Data source 3 Established associations between mechanisms and outcomes at skills and behavioural level, in a standardised simulated ward setting. Data source 1: The interpretation of data from seven focus groups involving sixty students identified reflection at two levels of Mezirow's descriptions; reflection and critical reflection as mechanisms that influence learning about error. Data source 2: Sixty-one students participated. The associations found, reflection and knowledge of actions to take for patient safety, r = 0.44 (P = 0.00) and critical reflection and intentions regarding patient safety, r = 0.40 (P = 0.00) Data source 3: Forty-eight students participated. The correlation identified associations between critical reflection and planned changes following feedback was, r = 0.48 (P = 0.00) and reflection and knowledge based errors r = -0.30 (P = 0.03). A realist approach identified two different levels of reflection were associated with different patient safety outcomes for this cohort of students. Critical reflection was associated with attitudes and reflection was associated with

    A 5-year survey (2009-2013) of antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) isolated from patients with bloodstream infections was carried out in Northeast Italy. No upward creep of glycopeptides MICs was documented among 582 nonduplicate MRSA blood isolates, which were tested in accordance with broth microdilution and interpreted in accordance with EUCAST recommendations. Teicoplanin showed stably a lower MIC50 in comparison with vancomycin (0.25-0.5 versus 1 mg/L). The activities of newer anti-MRSA antibacterials stratified by glycopeptides MICs showed similar trends in MICs of either vancomycin or teicoplanin with those of daptomycin, linezolid, and tigecycline. We hypothesize that in centers with different distribution of glycopeptides MICs, downward for teicoplanin and upward for vancomycin, teicoplanin could be a more effective alternative to vancomycin for empirical treatment of MRSA-related bacteremia.

    Background There is a debate that older patients with idiopathic pulmonary fibrosis (IPF) have a worse prognosis. We evaluated whether age affects the survival of patients with IPF. Methods The Korean Interstitial Lung Disease (ILD) Research Group conducted a national survey to evaluate the clinical, physiological, radiological, and survival characteristics of patients with IPF. A total of 1,663 patients with IPF were stratified into three groups according to age: (I) <60 years (n=309); (II) 60–69 years (n=613); and (III) ≥70 years (n=741). Results The 1-, 3- and 5-year observed survival rates were 83.0%, 62.6%, and 49.2% in the total population, respectively. The 1-, 3-, and 5-year relative survival rates were 85.7%, 69.1%, and 58.0% in all patients, respectively. The observed survival rate of the group ≥70 years of age was significantly lower than those of the other groups (P<0.001). In contrast, no significant difference in relative survival rate was detected among the three age groups. Compared with patients less than 60 years of age, patients with above 70 years of age had not increased risk of worse relative survival [P=0.252; hazard ratio (HR), 1.11; 95% confidence interval (CI), 0.76–1.64]. Conclusions The prognosis of patients above 70 years of age with IPF was not different to that of patients less than 60 years of age, using relative survival rate. Age may not affect survival in patients with IPF. PMID:28066605

    19 young children (less than 5 years old) have received 31 renal transplants from 4 live relatives and 27 cadaver donors. The 2-year allograft survival rate for the patients receiving their 1st allograft from the 4 live donors was 75 +/- 22% while for the patients receiving their 1st allograft from 15 cadaver donors was 26 +/- 11%. 10 children are currently surviving with functioning allographs (7 cadavers and 3 live relatives); 4 have died and 5 are undergoing dialysis after the loss of at least one allograft. Despite the poor allograft survival rate the fact that 7 children are surviving with cadaver allografts indicates that the lack of a living related donor should not prevent transplants in young children.

    Background and Objective. To determine the value of repeated brain CT in TBI cases for risk-stratified care management (RSCM) and to identify predicting factors which will change the neurosurgical management after repeated brain CTs. Methods. A 5-year retrospective study from January 2009 to August 2013 was conducted. The primary outcome was the value of repeated brain CT in TBI cases. The secondary outcome is to identify predicting factors which will change the neurosurgical management after repeated brain CTs. Results. There were 145 consecutive patients with TBI and repeated brain CT after initial abnormal brain CT. Forty-two percent of all cases (N = 61) revealed the progression of intracranial hemorrhage after repeated brain CT. In all 145 consecutive patients, 67.6% of cases (N = 98) were categorized as mild TBI. For mild head injury, 8.2% of cases (N = 8) had undergone neurosurgical management after repeated brain CT. Only 1 from 74 mild TBI patients with repeated brain CT had neurosurgical intervention. Clopidogrel and midline shift more than 2 mm on initial brain CT were significant predicting factors to indicate the neurosurgical management in mild TBI cases. Conclusion. Routine repeated brain CT for RSCM had no clinical benefit in mild TBI cases. PMID:27703812

    OBJECTIVE: We evaluated the incidence of and the main risk factors associated with cutaneous adverse events in patients with chronic inflammatory arthritis following anti-TNF-α therapy. METHODS: A total of 257 patients with active arthritis who were taking TNF-α blockers, including 158 patients with rheumatoid arthritis, 87 with ankylosing spondylitis and 12 with psoriatic arthritis, were enrolled in a 5-year prospective analysis. Patients with overlapping or other rheumatic diseases were excluded. Anthropometric, socioeconomic, demographic and clinical data were evaluated, including the Disease Activity Score-28, Bath Ankylosing Spondylitis Disease Activity Index and Psoriasis Area Severity Index. Skin conditions were evaluated by two dermatology experts, and in doubtful cases, skin lesion biopsies were performed. Associations between adverse cutaneous events and clinical, demographic and epidemiological variables were determined using the chi-square test, and logistic regression analyses were performed to identify risk factors. The significance level was set at p<0.05. RESULTS: After 60 months of follow-up, 71 adverse events (73.85/1000 patient-years) were observed, of which allergic and immune-mediated phenomena were the most frequent events, followed by infectious conditions involving bacterial (47.1%), parasitic (23.5%), fungal (20.6%) and viral (8.8%) agents. CONCLUSION: The skin is significantly affected by adverse reactions resulting from the use of TNF-α blockers, and the main risk factors for cutaneous events were advanced age, female sex, a diagnosis of rheumatoid arthritis, disease activity and the use of infliximab.

    To date, the relationship between metabolic syndrome factors and the risk of glioma-related depression is still unclear, and no study investigates this relationship. Our aim was to investigate the relationship between metabolic syndrome factors and the risk of postoperative depression in high-grade patients. A total of 386 high-grade glioma patients participated in blood sample collection for metabolic syndrome factors analysis and the hospital anxiety and depression scale testing. The association between metabolic syndrome factors and the risk of postoperative depression was assessed using Cox regression proportional hazards models, and Student's t tests were used to evaluate the differences in demographic variables and clinical characteristics in subgroups. The incidence of postoperative depression in our 1.5-year follow-up was 30.5%. We found the risk of postoperative depression was elevated with increased blood glucose level [hazard ratios (HR) 2.277, 95% confidence interval (CI) 1.201-4.320, top vs. bottom quartile]. The hazard ratio was increased for z-scores of blood glucose (HR 1.672 per unit standard deviation, 95% CI 1.311-2.133] and of the combined metabolic syndrome score (HR 1.080, 95% CI 1.000-1.167). In addition, risk of postoperative depression risk was increased in high-grade glioma patients with high blood glucose levels (≥6.0 mmol/l) (HR 2.084, 95% CI 1.235-3.515). However, we did not find significant associations between postoperative depression and other metabolic syndrome factors, including body mass index, systolic blood pressure, diastolic blood pressure, cholesterol, and triglycerides. Depression is prevalent among patients with high-grade glioma after operation. Blood glucose level is positively associated with the risk of postoperative depression, and might be involved in the etiology of postoperative depression, and may predict its development in high-grade glioma patients.

    Patients with metastatic breast cancer have traditionally been considered incurable with conventional treatment. However, 5-10% of those patients survive more than 5 years, and 2-5% survive more than 10 years. Recent studies suggest that the survival of patients with metastatic breast cancer has been slowly improving. In this review, we examine the possible curative approach for a certain group of patients with metastatic breast cancer. We identify that patients most likely to benefit from such an aggressive approach are young and have good performance status, adequate body functional reserve, long disease-free interval before recurrence, oligometastatic disease, and low systemic tumor load. An aggressive multidisciplinary approach including both local treatment of macroscopic disease and systemic treatment of microscopic disease can result in prolonged disease control in certain patients with metastatic breast cancer. Whether patients with prolonged disease control are "cured" remains controversial.

    In the present study, part of the Munich 5-year follow-up study on key relatives of first-hospitalized schizophrenic and depressive patients, baseline results with respect to relatives' burden and predictors of burden are presented. Basing on a transactional stress model the following hypothesis was tested: the impact of the patients' illness on their relatives' stress outcome is moderated by the psychosocial resources of the relatives. Stress outcome was measured in terms of objective and subjective burden, well-being, self-rated symptoms and global satisfaction with life. Potential moderating variables included age and gender, generalized stress response and illness-related coping strategies, beliefs of control,perceived social support,personality factors, expressed emotion and life stressors. A total of 83 relatives, whose ill family members had been hospitalized in the Department of Psychiatry of the Ludwig-Maximilians-University of Munich for the first time, participated in the study. Findings did not entirely support the hypothesis. On the one hand, relatives' stress outcome was independent of the objective stressors (severity of the illness, kind of symptoms, level of psychosocial functioning at admission). On the other hand, burden was significantly associated with several psychosocial resources and dispositions of the relatives. Multivariate linear regression analyses indicated that expressed emotion, emotion-focused coping strategies and generalized negative stress response are the most relevant predictors of burden. It is argued that a multidimensional approach in burden assessment is necessary and has relevant implications for improving family intervention strategies.

    Taliglucerase alfa, the first available plant cell-expressed recombinant therapeutic protein, is an enzyme replacement therapy approved for Gaucher disease (GD). PB-06-001, a pivotal phase 3, multicenter, randomized, double-blind, parallel-dose study investigated taliglucerase alfa 30 or 60U/kg every other week through 9months in treatment-naïve adults with GD; 30-month extension study PB-06-003 followed. Patients completing PB-06-001 and PB-06-003 could continue treatment in PB-06-007. Nineteen patients enrolled in PB-06-007 (30U/kg, n=8; 60U/kg, n=9; dose adjusted, n=2); 17 completed 5 total years of treatment. In these 3 groups, respectively, taliglucerase alfa resulted in mean decreases in spleen volume (-8.7, -6.9, -12.4 multiples of normal), liver volume (-0.6, -0.4, -0.5 multiples of normal), chitotriosidase activity (-83.1%, -93.4%, -87.9%), and chemokine (CC motif) ligand 18 concentration (-66.7%, -83.3%, -78.9%), as well as mean increases in hemoglobin concentration (+2.1, +2.1, +1.8mg/dL) and platelet count (+31,871, +106,800, +34,000/mm(3)). The most common adverse events were nasopharyngitis and arthralgia. Most adverse events were mild/moderate; no serious adverse events were considered treatment-related. These results demonstrate continued improvement of disease parameters during 5years of taliglucerase alfa therapy in 17 treatment-naive patients with no new safety concerns, extending the taliglucerase alfa clinical efficacy and safety dataset. This study was registered at www.clinicaltrials.gov as NCT01422187.

    Breast cancer is the most common cancer among Malaysian women. Other than hospital-based results, there are no documented population-based survival rates of Malaysian women for breast cancers. This population- based retrospective cohort study was therefore conducted. Data were obtained from Health Informatics Centre, Ministry of Health Malaysia, National Cancer Registry and National Registration Department for the period from 1st Jan 2000 to 31st December 2005. Cases were captured by ICD-10 and linked to death certificates to identify the status. Only complete data were analysed. Survival time was calculated from the estimated date of diagnosis to the date of death or date of loss to follow-up. Observed survival rates were estimated by Kaplan- Meier method using SPSS Statistical Software version 17. A total of 10,230 complete data sets were analysed. The mean age at diagnosis was 50.6 years old. The overall 5-year survival rate was 49% with median survival time of 68.1 months. Indian women had a higher survival rate of 54% compared to Chinese women (49%) and Malays (45%). The overall 5-year survival rate of breast cancer patient among Malaysian women was still low for the cohort of 2000 to 2005 as compared to survival rates in developed nations. Therefore, it is necessary to enhance the strategies for early detection and intervention.

    A number of studies have recently demonstrated a survival benefit in stage IV breast cancer patients following surgical resection of the primary tumor. Here, we investigate the relationship between loco-regional treatment and survival in patients with metastatic breast cancer and evaluate the impact of different loco-regional treatments. We conducted a systematic review of the literature using PubMed to analyze studies with the following criteria: Type of loco-regional treatment (surgery alone or combined with radiation, radiotherapy), overall survival, progression-free survival, selection factors for local treatment, and complication rates. Thirteen studies evaluated the effect of loco-regional treatment on overall survival with overall median survival increasing from a range of 12.6-28.3 months among patients without surgery to a range of 25-42 months among patients with surgery. In addition, six studies reported a 3-year survival benefit of 28-95% and 17-79% in women with and without locoregional therapy respectively. Two studies did not find any improvement in overall survival. One study found an improvement in 5-year breast cancer-specific survival of 27% with negative surgical margins versus 12% with no surgery. Three studies reported an advantage in progression-free survival in the treatment group compared with the non-treatment group. Loco-regional treatment for breast cancer patients with distant metastases at diagnosis is an important issue because of possible improvement of survival or disease-free survival. The possibility of surgery and/or radiotherapy following induction chemotherapy should be weighed and left to individual practice. Participation in randomized controlled trials should be encouraged.

    BRCA1-associated protein-1 (BAP1) mutations cause a new cancer syndrome, with a high rate of malignant mesothelioma (MM). Here, we tested the hypothesis that MM associated with germline BAP1 mutations has a better prognosis compared with sporadic MM. We compared survival among germline BAP1 mutation MM patients with that of all MM (N = 10 556) recorded in the United States Surveillance, Epidemiology, and End Results (SEER) data from 1973 to 2010. We identified 23 MM patients--11 alive--with germline BAP1 mutations and available data on survival. Ten patients had peritoneal MM, ten pleural MM and three MM in both locations. Thirteen patients had one or more malignancies in addition to MM. Actuarial median survival for the MM patients with germline BAP1 mutations was 5 years, as compared with <1 year for the median survival in the United States SEER MM group. Five-year survival was 47%, 95% confidence interval (24-67%), as compared with 6.7% (6.2-7.3%) in the control SEER group. Analysis of the pooled cohort of germline BAP1 mutation MM showed that patients with peritoneal MM (median survival of 10 years, P = 0.0571), or with a second malignancy in addition to MM (median survival of 10 years, P = 0.0716), survived for a longer time compared with patients who only had pleural MM, or MM patients without a second malignancy, respectively. In conclusion, we found that MM patients with germline BAP1 mutations have an overall 7-fold increased long-term survival, independently of sex and age. Appropriate genetic counseling and clinical management should be considered for MM patients who are also BAP1 mutation carriers.

  19. Gene signatures of drug resistance predict patient survival in colorectal cancer

    Different combinations of 5-fluorouracil (5-FU), oxaliplatin, irinotecan and other newly developed agents have been used to treat colorectal cancer. Despite the advent of new treatment regimens, the 5-year survival rate for metastatic colorectal cancer remains low (~10%). Knowing the drug sensitivity of a given tumor for a particular agent could significantly impact decision making and treatment planning. Biomarkers are proven to be successful in characterizing patients into different response groups. Using survival prediction analysis, we have identified three independent gene signatures, which are associated with sensitivity of colorectal cancer cells to 5-FU, oxaliplatin or irinotecan. On the basis of the three gene signatures, three score systems were developed to stratify patients from sensitive to resistance. These score systems exhibited robustness in stratify patients in two independent clinical studies. Patients with high scores in all three drugs exhibited the lowest survival. PMID:25179828

    Involvement of the gastrointestinal (GI) tract by bladder cancer is rare and documented in only a few case reports with no prognostic information available. The aim of this study was to clinicopathologically characterize patients with pathologically proven bladder cancer in the GI tract. We reviewed pathology reports from cystectomy patients at our institution from 2006 to 2011, identifying those with GI involvement at or after cystectomy. Overall survival (OS) was analyzed using Kaplan-Meier curves and Cox proportional hazard regression models. Twelve patients had surgical pathology specimens with GI involvement (anus, rectum, colon, and small bowel) at (n = 11) or within 4 months (n = 1) of cystectomy. These patients were noted to be pathologically staged inconsistently. GI involvement was a negative predictor of survival, with a 1.5-year OS of 25 versus 62 % without GI involvement (P < 0.001), similar to our pT4 patients (OS 26 %). In node-negative patients, there was a significantly worse 1.5-year OS with GI involvement compared to those without tumor in the GI tract (P = 0.005). We provide the first case series of patients with bladder cancer in the GI tract. GI involvement is a strong negative predictor of survival and behaves comparable to pT4 patients. However, we recommend that pathologists adhere to the current pT staging guidelines, in which GI involvement is not a criterion, until further research is conducted illustrating if and how it should be incorporated.

    Purpose: The impact of ABO blood group on the survival of patients with ovarian cancer remains uncertain. The aim of this study was to evaluate the prognostic value of the ABO blood group in ovarian cancer patients. Methods: 256 ovarian cancer patients who received a cytoreductive surgery were retrospectively reviewed. The prognostic impact of the ABO blood group with respect to overall survival (OS) was analyzed. Results: The median follow-up time was 57 months and the 5-year OS was 70.1%. The 5-year OS were 55.0%, 83.3%, 82.5%, and 70.0% in patients with A, B, AB, and O blood type, respectively (p = 0.003). Patients with blood type A had a poorer 5-year OS than patients with blood type non-A (55.0% vs. 75.0%, p = 0.001), especially in patients with age > 50 years (40.0% vs. 62.5%, p = 0.004). Univariate Cox analyses showed that blood type A was significantly associated with OS than those with non-A types (hazard ratio (HR) 2.210, 95% confidence interval (CI) 1.373-3.557, p = 0.001). Blood type A remained an independent prognostic factor for OS than those with non-A blood types in multivariate analyses (HR 2.235, 95% CI 1.360-3.674, p = 0.002). Conclusion: ABO blood group is associated with survival in patients with ovarian cancer, patients with blood type A had a significantly worse OS than patients with non-A blood types, especially in patients with age > 50 years.

    Objective: To clarify the clinicopathologic features of hepatocellular carcinoma (HCC) patients survived more than 10 years after radical hepatectomy. Methods: Two hundreds and fifty-two patients who underwent curative resection for HCC between January 1999 and March 2006 at Department of Hepatopancreatobiliary Surgery, Affiliated Hospital of Qingdao University were included.There were 217 male cases and 35 female cases aging from 17 to 82 years with median age of (53.8±10.5)years. Followed by March 31 2016, clinicopathologic factors in 10-year survivors and patients who died within 10 years were compared by χ(2) test, Kaplan-Meier survival analysis and Cox proportional hazards model and the prognostic factors affecting survival were identified. Results: All patients were followed-up for 4.0 to 205.7 months with median time of 53.4 months. The 10-year overall survival rate was 26%, there were 62 cases(26.2%) who survived for more than 10 years after initial hepatectomy. In survival >10-year group, the paitents with ALT<40 U/L, gamma-glutamyl transpeptidase<64 U/L, albumin≥35 g/L, without liver cirrhosis and portal hypertension, Child-Pugh grade A, no blood transfusion, AFP≤20 μg/L, tumor size ≤5.0 cm, single tumor, high differentiation, TNM stage Ⅰ and TACE negative after resection were more than the patients in survival <10-year group (P<0.05). In multivariate analysis, Child-Pugh grade A, the tumor size ≤5.0 cm and TACE negative after resection were favorable independent factors associated with 10-year survival (P<0.05). Conclusion: Based on the results of the study, Child-Pugh grade A, tumor size ≤5.0 cm and TACE negative after resection at initial hepatectomy might be biologically favorable conditions for patients surviving more than 10 years.

    Several research groups have examined the association between TP53 mutations and prognosis in human osteosarcoma. However, the results were controversial. The purpose of this study was to evaluate the prognostic value of TP53 mutations in osteosarcoma patients. A meta-analysis was conducted with all eligible studies which quantitatively evaluated the relationship between TP53 mutations and clinical outcome of osteosarcoma patients. Eight studies with a total of 210 patients with osteosarcoma were included in this meta-analysis. The risk ratio (RR) with a 95% confidence interval (95% CI) was calculated to assess the effect of TP53 mutations on 2-year overall survival. The quantitative synthesis of 8 published studies showed that TP53 mutations were associated with 2-year overall survival in osteosarcoma patients. These data suggested that TP53 mutations had an unfavorable impact on 2-year overall survival when compared to the counterparts with wild type (WT) TP53 (RR: 1.79; 95% CI: 1.12 to 2.84; P = 0.01; I2 = 0%). There was no between-study heterogeneity. TP53 mutations are an effective prognostic marker for survival of patients with osteosarcoma. However, further large-scale prospective trials should be performed to clarify the prognostic value of TP53 mutations on 3- or 5-year survival in osteosarcoma patients. PMID:27239089

    Purpose The aim of this study was to investigate survival in patients aged ≥70 years who underwent colorectal cancer surgery in 2003 and 2009. In addition, we aimed to identify the factors that could affect survival in these patients. Methods In a cross-sectional study, a retrospective review of the data for 878 patients who underwent colorectal cancer surgery with curative intent in the years 2003 and 2009 was performed. The primary outcome was the 5-year overall survival rate (5-OSR), and the clinicopathologic factors that could affect overall survival were analyzed. Results The 5-OSR was 77.8% and 84.9% in 2003 and 2009, respectively (P = 0.013). Age, American Society of Anesthesiologists physical status classification, stage, type of surgery, and length of hospital stay possibly affected survival per the univariate and multivariate analyses. In patients aged ≥70 years, the 5-OSR in 2009 was 75.9%, which showed improvement compared to 53.7% in 2003 (P = 0.027). The stage, type of surgery, and hospital stay were the variables that possibly affected survival in patients aged ≥70 years per the univariate analysis, whereas the stage (III; hazard ratio [HR], 2.188; P = 0.005) and length of hospital stay (>12 days; HR, 2.307; P = 0.004), were the variables that showed statistical significance on the multivariate analysis. Conclusion We found that early stage and shortening the length of hospital stay could affect survival in older patients with colorectal cancers. Because of limited evidence on the influence of shortening the length of hospital stay on survival in older patients, further investigations are warranted. PMID:28382291

    Monitoring of progress in cancer patient survival by cancer registries should be as up-to-date as possible. Period analysis has been shown to provide more up-to-date survival estimates than do traditional methods of survival analysis. However, there is a trade-off between up-to-dateness and the precision of period estimates, in that increasing the up-to-dateness of survival estimates by restricting the analysis to a relatively short, recent time period, such as the most recent calendar year for which cancer registry data are available, goes along with a loss of precision. The authors propose a model-based approach to maximize the up-to-dateness of period estimates at minimal loss of precision. The approach is illustrated for monitoring of 5-year relative survival of patients diagnosed with one of 20 common forms of cancer in Finland between 1953 and 2002 by use of data from the nationwide Finnish Cancer Registry. It is shown that the model-based approach provides survival estimates that are as up-to-date as the most up-to-date conventional period estimates and at the same time much more precise than the latter. The modeling approach may further enhance the use of period analysis for deriving up-to-date cancer survival rates.

    Pancreatic cancer (PaCa) is an aggressive malignancy with a high mortality rate and a poor prognosis. To evaluate treatment outcomes of patients with pancreatic cancer over the past three decades, data from the Surveillance, Epidemiology, and End Results (SEER) registries were used to assess the survival of patients with PaCa. A total of 63,530 patients diagnosed with pancreatic cancer between 1981 and 2010 were identified from nine original SEER registries. The 1-year relative survival rates (RSRs) improved each decade, from 17.0% to 19.9% to 28.2% (p < 0.0001), with a larger increase during the third decade than during the second decade. However, the long-term survival rates have remained very low. The 5-year RSRs increased from 3.1% to 4.4% to 6.9% over these three decades—i.e., still only few patients with PaCa survive more than 5 years. Furthermore, our analysis demonstrated that the survival rates for all the patients with pancreatic cancer were lower in patients of lower socioeconomic status and black race. These results will help predict future trends in PaCa incidence and survival, contribute to better-designed clinical trials by eliminating disparities that may affect the results, and thereby improve the clinical management and outcomes of PaCa.

    The impact of rehabilitation-induced changes in 6-minute walk distance (6MWD) on the survival of patients with chronic obstructive pulmonary disease (COPD) has not been fully elucidated. This study sought to determine the association of baseline 6MWD and its changes after pulmonary rehabilitation (PR) with 5-year survival in patients with COPD. Patients who were referred to a 12-week outpatient PR program were followed up for 5 years postcompletion, and survival status was verified. Survival was analyzed according to four groups based upon initial 6MWD (6MWDi) and its changes (Δ6MWD) after PR (Group 1: 6MWDi ≥350 m and Δ6MWD ≥30 m; Group 2: 6MWDi ≥350 m and Δ6MWD <30 m; Group 3: 6MWDi <350 m and Δ6MWD ≥30 m; and Group 4: 6MWDi <350 m and Δ6MWD <30 m) via Kaplan–Meier analysis and log rank test. Cox regression was performed to identify possible confounders of mortality estimates. In total, 423 patients (with mean ± standard deviation of forced expiratory volume in the first second [FEV1] 43±16% predicted, age 65±8 years, and 6WMDi 381±134 m) underwent PR between 1999 and 2010. Survival rates decreased progressively from Group 1 to Group 4 (Group 1, 81%; Group 2, 69%; Group 3, 47%; Group 4, 27%; log rank test, P<0.05). 6MWDi ≥350 m (hazard ratio [HR] 0.39 [95% confidence interval {CI} 0.30–0.50]) and Δ6MWD ≥30 m (HR 0.66 [95% CI 0.51–0.85]) were strongly and independently associated with survival. Compared with Group 1, mortality risks progressively increased in Group 2 (HR 1.36 [95% CI 0.92–2.00]; not significant), Group 3 (HR 1.90 [95% CI 1.28–2.84]; P=0.001), and Group 4 (HR 3.28 [95% CI 2.02–5.33]; P<0.0001). Both poor 6MWD and lack of improvement >30 m after PR are associated with worse 5-year survival in patients with COPD. PMID:27822029

    Abstract Esophageal cancer is the sixth leading cause of cancer mortality. More than 90% of patients with esophageal cancer in Taiwan have squamous cell carcinoma. Survival of such patients is related to socioeconomic status (SES). We studied the association between SES (individual and neighborhood) and the survival of working-age patients with esophageal cancer in Taiwan. A population-based study was conducted of 4097 patients diagnosed with esophageal cancer between 2002 and 2006. Each was traced for 5 years or until death. Individual SES was defined by enrollee job category. Neighborhood SES was based on household income and dichotomized into advantaged or disadvantaged. Multilevel logistic regression was used to compare the survival rates by SES group after adjustment for possible confounding and risk factors. Hospital and neighborhood SES were used as random effects in multilevel logistic regression. In patients younger than 65 years, 5-year overall survival rates were worst for those with low individual SES living in disadvantaged neighborhoods. After adjustment for patient characteristics, esophageal cancer patients with high individual SES had a 39% lower risk of mortality than those with low individual SES (odds ratio 0.61, 95% confidence interval 0.48–0.77). Patients living in disadvantaged areas with high individual SES were more likely to receive surgery than those with low SES (odds ratio 1.45, 95% confidence interval 1.11–1.89). Esophageal cancer patients with low individual SES have the worst 5-year survival, even with a universal healthcare system. Public health, education, and social welfare programs should address the inequality of esophageal cancer survival. PMID:27399129

We studied the association between SES (individual and neighborhood) and the survival of working-age patients with esophageal cancer in Taiwan. A population-based study was conducted of 4097 patients diagnosed with esophageal cancer between 2002 and 2006. Each was traced for 5 years or until death. Individual SES was defined by enrollee job category. Neighborhood SES was based on household income and dichotomized into advantaged or disadvantaged. Multilevel logistic regression was used to compare the survival rates by SES group after adjustment for possible confounding and risk factors. Hospital and neighborhood SES were used as random effects in multilevel logistic regression. In patients younger than 65 years, 5-year overall survival rates were worst for those with low individual SES living in disadvantaged neighborhoods. After adjustment for patient characteristics, esophageal cancer patients with high individual SES had a 39% lower risk of mortality than those with low individual SES (odds ratio 0.61, 95% confidence interval 0.48-0.77). Patients living in disadvantaged areas with high individual SES were more likely to receive surgery than those with low SES (odds ratio 1.45, 95% confidence interval 1.11-1.89). Esophageal cancer patients with low individual SES have the worst 5-year survival, even with a universal healthcare system. Public health, education, and social welfare programs should address the inequality of esophageal cancer survival.

    Background Cementless surface replacement hemiarthroplasty (CSRHA) is an established treatment for glenohumeral osteoarthritis; however, studies evaluating its role in arthritis with rotator cuff deficiency are limited. This study reviews the outcomes of CSRHA for glenohumeral osteoarthritis with and without rotator cuff tears. Methods 41 CSRHA (Mark III Copeland prosthesis) were performed for glenohumeral osteoarthritis with intact rotator cuffs (n = 21) and cuff-deficient shoulders (n = 20). Patients were assessed using Oxford and Constant questionnaires, patient satisfaction, range of motion measurements and by radiography. Results Mean age and follow-up were 75 years and 5.1 years, respectively. Functional gains were significantly higher in patients with intact rotator cuffs compared to cuff-deficient shoulders, with Oxford Shoulder Score improving from 18 to 37.5 and 15 to 27 and forward flexion improved from 60° to 126° and 44° to 77° in each group, respectively. Two patients with deficient cuffs had deficient subscapularis tendons; one of which was dislocated anteriorly. Conclusions CSRHA provides significant improvements in pain and function in patients with glenohumeral osteoarthritis. In patients with deficient cuffs, functional gains are limited, and should be considered in low-demand patients where pain is the primary problem. Caution should be taken in patients with a deficient subscapularis as a result of the risk of dislocation. PMID:27582984

    The effect of high-flux hemodialysis membranes on patient survival has not been unequivocally determined. In this prospective, randomized clinical trial, we enrolled 738 incident hemodialysis patients, stratified them by serum albumin ≤4 and >4 g/dl, and assigned them to either low-flux or high-flux membranes. We followed patients for 3 to 7.5 yr. Kaplan-Meier survival analysis showed no significant difference between high-flux and low-flux membranes, and a Cox proportional hazards model concurred. Patients with serum albumin ≤4 g/dl had significantly higher survival rates in the high-flux group compared with the low-flux group (P = 0.032). In addition, a secondary analysis revealed that high-flux membranes may significantly improve survival of patients with diabetes. Among those with serum albumin ≤4 g/dl, slightly different effects among patients with and without diabetes suggested a potential interaction between diabetes status and low serum albumin in the reduction of risk conferred by high-flux membranes. In summary, we did not detect a significant survival benefit with either high-flux or low-flux membranes in the population overall, but the use of high-flux membranes conferred a significant survival benefit among patients with serum albumin ≤4 g/dl. The apparent survival benefit among patients who have diabetes and are treated with high-flux membranes requires confirmation given the post hoc nature of our analysis. PMID:19092122

    Proliferation-associated antigen Ki-67 is used for the histological evaluation of different tumors. Few studies have been conducted on women with a resistant prolactinoma. To better define the characteristics and to evaluate the differences between patients with different Ki-67 labeling index (LI), a retrospective study was designed to recruit 199 females with a resistant prolactinoma. The patients were divided into two groups, patients with Ki-67 LI≥3% and patients with Ki-67 LI<3%. Tumors in the LI>3% group were also larger (p=0.043), had a higher rate of invasion (p=0.014), and were associated with more frequent polyuria and polydipsia (p=0.008) compared to the LI<3% group. The pre- and post-operative PRL levels in the LI>3% group remained significantly higher compared to patients with LI<3% (p<0.05). The incidences of transient diabetes insipidus and hyponatremia in the LI>3% group were also significantly higher (p=0.037, p=0.041). Additionally, the postoperative PRL normalization rate was lower in patients with LI>3% compared with patients with LI<3% (p=0.028). The recurrence rate in the LI>3% and LI<3% groups were 27.27% and 8.47%, respectively. In conclusion, high Ki-67 LI is predictive sign of a poor prognosis in women with resistant prolactinoma.

    Purpose: To retrospectively review our institutional experience with hypopharyngeal carcinoma with respect to treatment modality. Methods and Materials: A total of 70 patients with hypopharyngeal cancer treated between 1999 and 2009 were analyzed for functional and survival outcomes. The treatments included surgery alone (n = 5), surgery followed by radiotherapy (RT) (n = 3), surgery followed by chemoradiotherapy (CRT) (n = 13), RT alone (n = 2), CRT alone (n = 22), induction chemotherapy followed by RT (n = 3), and induction chemotherapy followed by CRT (n = 22). Results: The median follow-up was 18 months. The median overall survival and disease-free survival for all patients was 28.3 and 17.6 months, respectively. The 1- and 2-year local control rate for all patients was 87.1% and 80%. CRT, given either as primary therapy or in the adjuvant setting, improved overall survival and disease-free survival compared with patients not receiving CRT. The median overall survival and disease-free survival for patients treated with CRT was 36.7 and 17.6 months vs. 14.0 and 8.0 months, respectively (p < .01). Of the patients initially treated with an organ-preserving approach, 4 (8.2%) required salvage laryngectomy for local recurrence or persistent disease; 8 (16.3%) and 12 (24.5%) patients were dependent on a percutaneous gastrostomy and tracheostomy tube, respectively. The 2-year laryngoesophageal dysfunction-free survival rate for patients treated with an organ-preserving approach was estimated at 31.7%. Conclusions: Concurrent CRT improves survival in patients with hypopharyngeal cancer. CRT given with conventional radiation techniques yields poor functional outcomes, and future efforts should be directed at determining the feasibility of pharyngeal-sparing intensity-modulated radiotherapy in patients with hypopharyngeal tumors.

    The current TNM staging system did not provide disease relapse information. The aim of study was try to establish a predictive survival model for disease and overall survival in nonsmall cell lung cancer patients who presented as resectable disease and to develop a reference for follow-up imaging tool selection.From January 2005 to December 2011, 442 patients who initially presented as resectable disease (stages I-IIIa) and received anatomic resection and mediastinal lymph node dissection were included in the study.Medical charts were thoroughly reviewed and clinico-pathologic factors were collected and analyzed.Visceral pleural invasion, tumor size >5 cm, and postoperative adjuvant therapy were identified as risk factors for poorer disease-free survival. The 5-year disease-free survival from score 0 to 3 was 68.7%, 46.6%, 31.9%, and 26.1%, respectively. The disease relapse percentage for scores 0 to 3 were 26.49%, 50.61%, 65.05%, and 73.81%, respectively. For analysis of overall survival, age >60 years, tumor size >3 cm, and total metastatic lymph node ratio >0.05 were correlated to worse overall survival. Because greater age may be correlated with poor general condition, we re-scored risk factors that correlated to disease severity that ranging from 0 to 2. The 5-year overall survival range from score 0 to 2 was 56.3%, 43.1%, and 13.1%, respectively.Poor prognostic factors correlated to disease-free survival were tumor size >5 cm, visceral pleural invasion, and patients needing to receive postoperative adjuvant therapy. Disease-free survival of resectable nonsmall cell lung cancer patients and disease relapse can be stratified by these 3 factors. Chest tomography may be recommended for patients with 1 or more poor disease-free survival risk factors.

    OBJECTIVES: The objective of this study was to contribute long-term safety data for infliximab and other therapies in Crohn's disease (CD). METHODS: We prospectively evaluated CD patients enrolled in the large, observational Crohn's Therapy, Resource, Evaluation, and Assessment Tool registry, established to compare infliximab safety with conventional nonbiological medications in CD. RESULTS: A total of 6,273 patients were enrolled and evaluated on or before 23 February 2010; 3,420 received infliximab (17,712 patient-years; 89.9% received ≥2 infusions) and 2,853 received other-treatments-only (13,251 patient-years). Mean length of patient follow-up was 5.2 years. More infliximab- than other-treatments-only-treated patients had moderate-to-severe (30.6% vs. 10.7%) or severe-to-fulminant (2.5% vs. 0.6%) disease severity (P<0.001). In the year before enrollment, more infliximab- than other-treatments-only-treated patients required surgical intervention (17.4% vs. 13.6%), medical hospitalization (14.2% vs. 8.8%), prednisone (47.8% vs. 31.4%), immunomodulators (52.0% vs. 32.1%), and narcotic analgesics (17.3% vs. 9.1%). Patient mortality was similar for infliximab- and other-treatments-only-treated patients (0.58 vs. 0.59/100 patient-years). In multivariate logistic regression analyses, treatment with prednisone (hazard ratio (HR)=2.14, 95% confidence interval (CI)=1.55, 2.95; P<0.001) or narcotic analgesics (HR=1.79, 95% CI=1.29, 2.48; P<0.001) and age (HR=1.08, 95% CI=1.07, 1.09; P<0.001) were associated with increased mortality risk. Neither infliximab nor immunomodulator treatment was associated with increased mortality risk. Factors independently associated with serious infections included moderate-to-severe disease activity (HR=2.24, 95% CI=1.57, 3.19; P<0.001), narcotic analgesic treatment (HR=1.98, 95% CI=1.44, 2.73; P<0.001), prednisone therapy (HR=1.57, 95% CI=1.17, 2.10; P=0.002), and infliximab treatment (HR=1.43, 95% CI=1.11, 1.84; P=0.006).

    Presented here are the 5-year end-of-study results from the pivotal phase 2 trial of brentuximab vedotin in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL) after failed hematopoietic autologous stem cell transplantation. At 5 years, the overall patient population (N = 102) had an estimated overall survival (OS) rate of 41% (95% confidence interval [CI]: 31-51) and progression-free survival (PFS) rate of 22% (95% CI: 13-31). Patients who achieved a complete response (CR) to brentuximab vedotin (N = 34) had estimated OS and PFS rates of 64% (95% CI: 48-80%) and 52% (95% CI: 34-69%), respectively. The median OS and PFS were not reached in CR patients, with 13 patients (38% of all CR patients) remaining in follow-up and in remission at study closure. Of the 13 patients, 4 received consolidative hematopoietic allogeneic stem cell transplant, and 9 (9% of all enrolled patients) remain in sustained CR without receiving any further anticancer therapy after treatment with brentuximab vedotin. Of the patients who experienced treatment-emergent peripheral neuropathy, 88% experienced either resolution (73%) or improvement (14%) in symptoms. These 5-year follow-up data demonstrate that a subset of patients with R/R HL who obtained CR with single-agent brentuximab vedotin achieved long-term disease control and may potentially be cured. The trial was registered at www.clinicaltrials.gov as #NCT00848926. PMID:27432875

    Even with the availability of targeted drugs, allogeneic hematopoietic cell transplantation (allo-HCT) is the only therapy with curative potential for patients with CLL. Cure can be assessed by comparing long-term survival of patients to the matched general population. Using data from 2589 patients who received allo-HCT between 2000 and 2010, we used landmark analyses and methods from relative survival analysis to calculate excess mortality compared with an age-, sex- and calendar year-matched general population. Estimated event-free survival, overall survival and non-relapse mortality (NRM) 10 years after allo-HCT were 28% (95% confidence interval (CI), 25-31), 35% (95% CI, 32-38) and 40% (95% CI, 37-42), respectively. Patients who passed the 5-year landmark event-free survival (N=394) had a 79% probability (95% CI, 73-85) of surviving the subsequent 5 years without an event. Relapse and NRM contributed equally to treatment failure. Five-year mortality for 45- and 65-year-old reference patients who were event-free at the 5-year landmark was 8% and 47% compared with 3% and 14% in the matched general population, respectively. The prospect of long-term disease-free survival remains an argument to consider allo-HCT for young patients with high-risk CLL, and programs to understand and prevent late causes of failure for long-term survivors are warranted, especially for older patients.

    Aims and Objective: The objectives of this study were to evaluate the epidemiology, clinical variable of chemical burns, and their outcomes to prevent or reduce the frequency and morbidity of such injuries. Materials and Methods: A retrospective analysis was performed on all the patients with chemical burns admitted at author's center between November 2008 and December 2013. All the patients were evaluated in terms of age, sex, total body surface area, etiology, treatment given, morbidity, mortality, final outcome, and then educated regarding specific preventive measures. Results: A total of 96 patients (2.4% of total burn admissions) (42 males and 54 females) were admitted to our hospital with chemical burn injuries. Most of the patients were in the age group of 16–30 years. Incidence in females was slightly higher than in males. Acid was found to be the most common cause of injury. We found 55% patients admitted had <10% total body surface area (TBSA) involvement, 35% had burns involving between 11 and 20% TBSA, and 4% had burns involving 21–30% TBSA, and 6% had burns in >30% TBSA. Morbidity was noticed in the form of skin defect in 80% of cases, soft tissue defect with exposed tendon, bone, or vessels in 16% of cases, and 4% of patients developed contracture and hypertrophic scar. Eighty-six percent of patients required operative intervention. A total of three deaths (3%) were recorded. Conclusion: It was found that chemical burns, though not very common, are deeper burns and can be accidental or non-accidental, and the high-risk age group is 16–25 years. Chemical burns are largely preventable and if properly managed have a good outcome. PMID:25810999

    Although oxidized low-density lipoprotein (LDL) and lysophosphatidylcholine (LPC) have been proposed as important mediators of the atherosclerosis, the long-term contribution to the risk of cardiovascular disease (CVD) in hemodialysis patients has not been evaluated. This study investigated the relation between oxidized LDL and LPC levels with long term risk of CVD. Plasma oxidized LDL and LPC levels were determined in 69 Korean hemodialysis patients as a prospective observational study for 5 yr. During the observation period, 18 cardiovascular events (26.1%) occurred including 6 deaths among the hemodialysis patients. The low LPC level group (≤ 254 µM/L, median value) had much more increased risk of CVD compared to the high LPC level group (> 254 µM/L) (P = 0.01). However, serum levels of oxidized LDL were not significantly different between groups with and without CVD. In adjusted Cox analysis, previous CVD, (hazard ratio [HR], 5.68; 95% confidence interval [CI], 1.94-16.63, P = 0.002) and low LPC level (HR, 3.45; 95% CI, 1.04-11.42, P = 0.04) were significant independent risk factors for development of CVD. It is suggested that low LPC, but not oxidized LDL, is associated with increased risk of CVD among a group of Korean hemodialysis patients.

    Purpose: Pharyngeal and laryngeal carcinomas (PLC) are among the top leading cancers in Asian populations. Typically the tumor may recur and progress in a short period of time if radiotherapy fails to deliver a successful treatment. Here we used image texture features extracted from images of computed tomography (CT) planning and conducted a retrospective study to evaluate whether texture analysis is a feasible approach to predict local tumor recurrence for PLC patients received radiotherapy treatment. Methods: CT planning images of 100 patients with PLC treated by radiotherapy at our facility between 2001 and 2010 are collected. These patients were received two separate CT scans, before and mid-course of the treatment delivery. Before the radiotherapy, a CT scanning was used for the first treatment planning. A total of 30 fractions were used in the treatment and patients were scanned with a second CT around the end of the fifteenth delivery for an adaptive treatment planning. Only patients who were treated with intensity modulated radiation therapy and RapidArc were selected. Treatment planning software of Eclipse was used. The changes of texture parameters between two CT acquisitions were computed to determine whether they were correlated to the local tumor recurrence. The following texture parameters were used in the preliminary assessment: mean, variance, standard deviation, skewness, kurtosis, energy, entropy, inverse difference moment, cluster shade, inertia, cluster prominence, gray-level co-occurrence matrix, and gray-level run-length matrix. The study was reviewed and approved by the committee of our institutional review board. Results: Our calculations suggested the following texture parameters were correlated with the local tumor recurrence: skewness, kurtosis, entropy, and inertia (p<0.0.05). Conclusion: The preliminary results were positive. However some works remain crucial to be completed, including addition of texture parameters for different image

    The role of diffusely adherent Escherichia coli (DAEC) in diarrheal disease has been controversial. However, DAEC strains were recently implicated in diarrheal disease in developing countries. To clarify whether DAEC are prevalent among sporadic cases of diarrheal illness in Osaka City, Japan, E. coli strains isolated between July 1997 and March 2000 during diarrheagenic E. coli (DEC) investigation were retrospectively examined. DAEC strains were recognized among 41 (4.4%) of 924 patients and formed the biggest subgroup of DEC. Previously, we reported that some DAEC strains caused epithelial cells to secrete as much IL-8 as enteroaggregative E. coli strains did. In this study, we attempted to evaluate epidemiologically whether the ability of DAEC to induce IL-8 was involved in the pathogenesis. Relationship among patient age, symptoms, Afa adhesins, season and IL-8 induction were examined. The subgroup of DAEC that possessed Afa genes and/or induced a high level of IL-8 was significantly prevalent among patients age 1 to 4 years; however total DAEC was not significantly high among the children compared to other age group. IL-8 inducing DAEC seems to play a role in causing sporadic diarrheal illnesses, particularly in pediatric fields. Investigations highlighting the relationship between IL-8 induction and enteropathogenicity are clearly necessary to confirm the role of DAEC in infectious enteritis.

    The importance of "operative timing" in cirrhotic patients with variceal hemorrhage is often underemphasized. To evaluate the effects of immediate versus delayed selective portasystemic decompression on hepatic function, operative mortality, and long-term patient survival, we reviewed the records of 77 patients who underwent distal splenorenal shunts (DSRS) over a 14-year period. A hepatic risk status score was calculated at the time of the index bleed (HRS1) or presentation and again just prior to operation (HRS2). Variables analyzed included age, sex, prior bleeding episodes, time from index bleed to operation, transfusion requirements, and etiology of cirrhosis. Operative mortality rates for immediate versus delayed DSRS were 46.2 per cent and 17 per cent, respectively. HRS improved significantly in elective DSRS patients from 1.46 to 1.30. Predictors of HRS2 included HRS1 and time in days from the index bleed to operation. The most important predictor of early survival for all patients after elective DSRS was the HRS2; however, for patients who underwent elective DSRS and survived, HRS1 was a better predictor of length of survival than HRS2. No other variable analyzed accurately predicted survival. We conclude that HRS can be expected to improve with supportive inhospital therapy; improved HRS at the time of operation is associated with decreased operative mortality; and the extent of liver disease as determined by HRS1 appears to be the chief determinant of long-term patient survival.

    This paper provides a survival analysis of End Stage Renal Disease (ESRD) under Kaplan-Meier Estimates and Weibull Distribution. The data were obtained from the records of V. L. MakabaliMemorial Hospital with respect to time t (patient's age), covariates such as developed secondary disease (Pulmonary Congestion and Cardiovascular Disease), gender, and the event of interest: the death of ESRD patients. Survival and hazard rates were estimated using NCSS for Weibull Distribution and SPSS for Kaplan-Meier Estimates. These lead to the same conclusion that hazard rate increases and survival rate decreases of ESRD patient diagnosed with Pulmonary Congestion, Cardiovascular Disease and both diseases with respect to time. It also shows that female patients have a greater risk of death compared to males. The probability risk was given the equation R = 1 — e-H(t) where e-H(t) is the survival function, H(t) the cumulative hazard function which was created using Cox-Regression.

    The aim of this study was to evaluate the ability of high-resolution computerized tomography (HRCT) of the chest and chest x-rays (CXR) to determine efficacy of inhaled recombinant human DNase (rhDNase) in cystic fibrosis (CF) patients younger than 5 years of age. A randomized, double-blind, placebo-controlled pilot study of 12 patients with CF younger than 5 years of age, attending the University of Michigan Cystic Fibrosis Center (Ann Arbor, MI) was conducted. The changes in the HRCT and CXR score from baseline to day 100 of therapy were assessed using a previously validated scoring system. The mean changes of HRCT scores between the rhDNase and placebo groups were found to be significant at the 95% level, with mean change +/- SE mean of - 1.00 +/- 0.53 and 0.58 +/- 0.24 for rhDNase and placebo groups, respectively (P = 0.02). The difference in CXR score was not significant between the two groups. An analysis was performed to relate HRCT subscores to CXR score; only thickening of the intra-interlobular septae was significantly correlated with the total CXR score (r = - 0.7, P < 0.01). There was improvement in the parents' assessments of the patients' well-being, with improvement in physical activity, decreased cough, sleep quality, and appetite in those subjects receiving rhDNase. We conclude that the administration of rhDNase was associated with improvement in the HRCT scan in CF patients younger than 5 years of age. Findings indicate that HRCT of the chest is useful and sensitive in studying responses to therapy in patients with CF lung disease. To our knowledge, this is the first report of the use of HRCT to assess the effectiveness of a therapeutic modality in so young a CF patient population.

    Background In 2009 to 2011, the commonest cause of death was by cancer in Brunei Darussalam, and 16.5% and 19.5% of cancer deaths were due to lung cancer in 2004 and 2011 respectively. This study was to investigate the survival of lung cancer patients in Brunei Darussalam. Methods This retrospective cohort study was conducted in 2013 & 2014 for those who were diagnosed as primary lung cancer in the period of 1987 to 2012. Data were retrieved from patients’ medical records and death certificates using pretested data collection form. Survival analyses namely Kaplan-Meier method, and log-rank test to compare survival between groups. Results We retrieved 630 primary lung cancer records. Majority was diagnosed at the late stages, 42.5% at Stage IV & 33.4% at Stage III. The overall median survival time was 6.1 months whereas 2.6 and 79.1 months for Stage IV and Stage I respectively. The overall 6-month, 1-, 3- and 5-year survival rates were 50.2%, 32.1%, 14.5% and 8.8% respectively. Survival duration had significantly improved from 1987–1999 to 2000–2012 (P=0.001) although significant higher proportion of Stage IV was diagnosed in the second period (P=0.008). Conclusions Overall survival rates and duration of primary lung cancer in Brunei Darussalam were comparable with some developed countries. However, through effective public intervention such as increase awareness, early case detection, and effective anti-smoking strategies, survival of lung cancer patients can certainly be improved and the burden of disease can be reduced.

    Objective We evaluated long-term impact of sustained weight loss versus weight regain on cardiovascular risk factors in real-world clinical practice. Methods We evaluated 129 obese patients with diabetes enrolled in Weight Achievement and Intensive Treatment (Why WAIT) program, a 12-week clinical model of intensive lifestyle intervention. After 1 year, we divided participants into group A, who maintained <7% weight loss (47.3%) and group B (52.7%), who maintained ≥7% weight loss. We continued to follow them for a total of 5 years. Results The total cohort lost 23.8 lbs (−9.7%) at 12 weeks and maintained −16.2 lbs (−6.4%) at 5 years (p<0.001). Group A maintained −8.4 lbs (−3.5%) and group B maintained −23.1 lbs (−9.0%) at 5 years. In group A, A1C decreased from 7.5±1.3% to 6.7±0.9% at 12 weeks but increased to 7.7±1.4% at 1 year and 8.0±1.9% at 5 years. In group B, A1C decreased from 7.4±1.2% to 6.4±0.9% at 12 weeks and rose to 6.8±1.2% at 1 year and 7.3±1.5% at 5 years. Despite weight regain, group A maintained improvement in low-density lipoprotein-cholesterol and high-density lipoprotein-cholesterol with worsening of serum triglycerides and no change in blood pressure (BP). Group B maintained improvement in lipid profile for 5 years and had significantly lower BP for 18 months. Conclusions Weight reduction in patients with diabetes can be maintained for 5 years and is predicted by patients’ ability to maintain ≥7% weight loss at 1 year. A1C and triglycerides deteriorate with weight regain, while other lipid improvements are maintained. Sustained weight loss is associated with significantly lower A1C for 5 years and lowers BP for 18 months. Trial registration number NCT01937845. PMID:28090332

    The purpose of this study was to determine the survival and prognostic factors of patients with diffuse large B-cell lymphoma (DLBCL) of the oral cavity and maxillofacial region. Retrospectively, the clinical records of patients with a primary diagnosis of DLBCL of the oral cavity and maxillofacial region treated at the A.C. Camargo Hospital for Cancer, São Paulo, Brazil, between January 1980 and December 2005 were evaluated to determine (A) overall survival (OS) at 2 and 5 years and the individual survival percentage for each possible prognostic factor by means of the actuarial technique (also known as mortality tables), and the Kaplan Meier product limit method (which provided the survival value curves for each possible prognostic factor); (B) prognostic factors subject to univariate evaluation with the log-rank test (also known as Mantel-Cox), and multivariate analysis with Cox's regression model (all the variables together). The data were considered significant at p≤0.05. From 1980 to 2005, 3513 new cases of lymphomas were treated, of which 151 (4.3%) occurred in the oral cavity and maxillofacial region. Of these 151 lesions, 48 were diffuse large B-cell lymphoma, with 64% for OS at 2 years and 45% for OS at 5 years. Of the variables studied as possible prognostic factors, multivariate analysis found the following variables have statistically significant values: age (p=0.042), clinical stage (p=0.007) and performance status (p=0.031). These data suggest that patients have a higher risk of mortality if they are older, at a later clinical stage, and have a higher performance status.

    Renal involvement with amyloidosis is common but causes patient survival to be poor, rarely reaching 5 years. In this study, we retrospectively reviewed clinical and biological characteristics as well as treatments and outcomes of patients with renal amyloidosis followed for more than 5 years. Between 1975 and 2003, 485 patients were diagnosed with renal amyloidosis including only 12 patients who were followed more than 5 years. The six men and six women of mean age 42.4 years (range 18 to 66 years) displayed renal signs of lower limb edema in all cases; hypertension in four cases, proteinuria on urinalysis in all cases with microscopic hematuria in five cases. Biological tests showed nephrotic syndrome in 11 patients, normal renal function in nine patients, and renal failure in three patients whose mean creatinine was 481.6 micromol/L (range 294 to 726). The amyloidosis was AA type in 11 cases and non-AA in one case. An etiologic survey revealed spondylarthropathy in one patient, pulmonary tuberculosis in two patients, chronic bronchitis in three patients, hepatic hydatic cyst in one patient, Mediterranean familial fever in two patients, Crohn's disease in one patient, Hodgkin's lymphoma in one patient, and multiple myeloma in one patient. Specific treatment was initiated with colchicine in seven patients. At a 110-month mean follow-up (range 53 to 153 months), remission of nephrotic syndrome was observed in four cases, progression to chronic renal failure in two patients, and to end-stage renal failure in five cases (range 53 to 196 months), with stabilization of renal function in seven patients. In conclusion, primary amyloid disease should be optimally suppressed in patients with renal involvement. The role of this treatment in remission of renal amyloidosis is not well established. This efficacy of the treatment has been demonstrated in some patients with improved survival.

    Thymomas are the most common adult tumors in the anterior mediastinal compartment, and a significant amount of thymomas are complicated by myasthenia gravis (MG). Extended thymectomy (ET) is the primary treatment method for thymomas and is used to completely resect possible ectopic thymus to avoid recurrence. Studies on the effect of MG in thymoma patients following ET are limited. The aim of the present study was to determine whether the presence of MG affects the prognosis of patients with thymoma. The present study consisted of 104 patients with thymoma that underwent ET; 61 men (58.7%) and 43 women (41.3%) (mean age, 54.6 years). In total, 38 patients had MG (36.5%). MG was most frequently observed in World Health Organization (WHO) classification type B2 thymoma compared with other types of thymoma. During the 5-year follow-up period, 11 patients succumbed to a recurrence of thymoma or respiratory failure due to MG. The overall 5-year survival rate in patients without MG or with MG was 89.1 and 76.0%, respectively. The overall survival (OS) rate in patients with Masaoka stages I + II and III + IV was 90.0 and 68.0%, respectively. The OS rate in patients with WHO type A + AB + B1 and type B2 + B3 was 96.9 and 76.8%, respectively. The patients with MG (P=0.026), Masaoka stages III + IV (P=0.008) and WHO type B2 + B3 (P=0.032) had a poorer prognosis compared with patients without these characteristics. Furthermore, multivariate analysis by Cox regression revealed that age [P=0.032; relative risk (RR)=1.097; 95% confidence interval (CI)=1.097–1.192] and MG (P=0.042; RR=0.167; 95% CI=0.037–0.940) significantly affected OS rate. In summary, ET is a reliable method for the treatment of thymoma. Long-term survival is expected for patients at early Masaoka stages, and for patients without MG. The prognosis of patients with thymomas with MG is poorer compared with patients without MG. The present findings provide useful information for the future management of

    Objectives: To analyze the relationship between clinical features, hormonal receptor status, and survival in patients who were diagnosed with medullary breast cancer (MBC). Methods: Demographic characteristics, histopathological features, and survival statuses of 201 patients diagnosed with MBC between 1995 and 2015 were retrospectively recorded. Survival analyses were conducted with uni- and multivariate cox regression analysis. Results: Median follow-up time was 54 (4-272) months. Median patient age at the time of diagnosis was 47 years old (26-90). Of the patients, 91.5% were triple negative. Five-year recurrence free survival time (RFS) rate was 87.4% and overalll survival (OS) rate 95.7%. For RFS, progesterone receptor (PR) negativity, atypical histopathological evaluation, absence of lymphovascular invasion, smaller tumor, lower nodal involvement were found to be favourable prognostic factors by univariate analysis (p<0.05). The PR negativity and smaller tumor were found to be favourable factors by univariate analysis (p<0.05). However, none of these factors were determined as significant independent prognostic factors for OS (p>0.05). Conclusion: Turkish MBC patients exhibited good prognosis, which was comparable with survival outcomes achieved in the literature. The PR negativity was related to a better RFS and OS rates.

    It has been postulated that transfusions have immunosuppressive effects that promote tumor growth and metastasis. Moreover perioperative anemia is considered an independent prognostic factor on outcome in patients operated for malignancy. We evaluated the influence of red blood cell (RBC) transfusions and perioperative anemia on survival in non-small cell lung carcinoma (NSCLC) patients. From 1999 through 2005, 331 consecutive patients, male/female=295/36 (mean age 64+/-9 years), who underwent radical surgery for NSCLC were prospectively enrolled in this cohort and followed up for a mean of 27.2 months. The overall survival of patients was analyzed in relation to RBC transfusions and perioperative anemia. These parameters were analyzed in the whole cohort of patients and separately for stage I patients. Patients were divided according to perioperative transfusion, into Group A (transfused) and Group B (non-transfused) and according to the preoperative haemoglobin (Hb) level into Group 1(Hb<12g/dl) and Group 2(Hb> or =12g/dl), respectively. The overall transfusion rate was 25.7%. Univariate analysis showed that in the whole cohort of patients overall survival was significantly shorter in Group A (mean 33.6 months, 5-year survival 25.1%) compared to Group B (mean 48.0 months, 5-year survival 37.3%) (p=0.001). It also showed that patients with preoperative Hb level <12g/dl (Group 1), (mean of 33.0 months, 5-year survival 21.3%) had shorter survival compared to Group 2 patients (mean 49.3 months and 5-year survival 40.0%), respectively (p=0.002). Multivariate analysis in the whole cohort of patients showed that preoperative anemia was an independent risk factor for survival while RBC transfusion was not. In particular for stage I patients, it was shown that RBC transfusion was an independent prognostic factor for long-term survival as detected by multivariate analysis (p=0.043), while anemia was not. RBC transfusions affect adversely the survival of stage I NSCLC

    The natural history of amyotrophic lateral sclerosis (ALS) and patient risk stratification are areas of considerable research interest. We aimed (1) to describe the survival of a representative cohort of French ALS patients, and (2) to identify covariates associated with various patterns of survival using a risk classification analysis. ALS patients recruited in the FRALim register (2000-2013) were included. Time-to-death analyses were performed using Kaplan-Meier method and Cox model. A recursive partitioning and amalgamation (RECPAM) algorithm analysis identified subgroups of patients with different patterns of survival. Among 322 patients, median survival times were 26.2 and 15.6 months from time of onset and of diagnosis, respectively. Four groups of patients were identified, depending on their baseline characteristics and survival (1) ALSFRS-R slope >0.46/month and definite or probable ALS (median survival time (MST) 10.6 months); (2) ALSFRS-R slope >0.46/month and possible or probable laboratory-supported ALS (MST: 18.1 months); (3) ALSFRS-R slope ≤0.46/month and definite or probable ALS (MST: 22.5 months), and (4) ALSFRS-R slope ≤0.46/month and possible or probable laboratory-supported ALS (MST: 37.6 months). Median survival time is among the shortest ever reported by a worldwide population-based study. This is probably related to the age structure of the patients (the oldest identified to date), driven by the underlying population (30 % of subjects older than 60 years). Further research in the field of risk stratification could help physicians better anticipate prognosis of ALS patients, and help improve the design of randomized controlled trials.

    The principle advantages of open rhinoplasty concern diagnosis as well as technical facilities. The transcolumelar approach, initially described by Rheti in 1934 for surgical corrections of the cleft lip nose, was adopted by us since 1992 in 48 patients. We have systematically made a "staggered incision" at the collumella's narrowest point, that allows a great view of nasal structures. The results were considered good, even in difficult rhinoplasties. The scars were inconspicous, without cicatricial hypertrophies or deformities.

    Nimotuzumab (h-R3) is a humanized monoclonal antibody that is safe to use against epidermal growth factor receptor (EGFR). However, the available information is insufficient about the dose effect of monoclonal antibody against epidermal growth factor receptor for the treatment of esophageal squamous cell carcinoma (ESCC). We retrospectively recruited 66 patients with ESCC who were treated with h-R3 and chemoradiotherapy/radiotherapy. Patients who received more than 1,200 mg of h-R3 were classified as the high-dose group, and the remaining patients were classified as the low-dose group. The endpoint for efficacy was the overall survival. Differences in survival between the groups were analyzed using the log-rank test. The Cox proportional hazards model was used in multivariate analysis to identify independent prognostic factors. The low-dose and high-dose groups comprised 55 and eleven patients, respectively. The median follow-up time in the final analysis was 46 months. The high-dose group showed no increased incidence of toxicities compared to the low-dose group. The 1-, 2-, and 5-year overall survival rates in the low-dose and high-dose groups were 66.9%, 50.0%, 31.5% and 90.0%, 80.0%, 66.7%, respectively (P=0.04). Multivariate analyses showed that the high-dose group had better survival than the low-dose group (hazard ratio 0.28, 95% confidence interval 0.09–0.94, P=0.039). Taken together, high-dose h-R3 showed limited toxicity and improved survival in patients with ESCC. PMID:26766917

    Patient survival after cardiac arrest can be improved significantly with prompt and effective resuscitative care. This systematic review analyzes the basic life support factors that improve survival outcome, including chest compression technique and rapid defibrillation of shockable rhythms. For patients who are successfully resuscitated, comprehensive postresuscitation care is essential. Targeted temperature management is recommended for all patients who remain comatose, in addition to careful monitoring of oxygenation, hemodynamics, and cardiac rhythm. Management of cardiac arrest in circumstances such as pregnancy, pulmonary embolism, opioid overdose and other toxicologic causes, hypothermia, and coronary ischemia are also reviewed.

    Data indicate a better prognosis for human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC). HPV and p16 detection are established markers for HPV-related HNSCC. Both are accepted as survival-independent predictors. Previous studies investigating the survival in HNSCC patients depending on HPV(+/-) and p16(+/-) status consistently found discordant results with p16(-)/HPV(+) and p16(+)/HPV(-). However, no meta-analysis regarding the survival according to combined HPV/p16 status has been performed yet. The objective of this study was to discriminate the impact of combined HPV(+/-) and p16(+/-) status on survival. Data sources were identification and review of publications assessing survival of the distinct subgroups with both p16 and HPV investigated in HNSCC until February, 2015. A meta-analysis was performed to classify survival and clinical outcomes. 18 out of 397 articles (4424 patients) were eligible for the meta-analysis. The percent proportion of the subgroups was 25 % for HPV(+)/p16(+), 61.2 % for HPV(-)/p16(-), 7.1 % for HPV(-)/p16(+) and 6.8 % for HPV(+)/P16(-). The meta-analysis showed a significantly improved 5-year overall survival (OS), 5-year disease-free survival and their corresponding hazard ratio for HPV(+)/p16(+) HNSCC in comparison to HPV(-)/p16(-), HPV(+)/p16(-) and HPV(-)/p16(+). The 5-year OS of the HPV(-)/p16(+) subgroup was intermediate while HPV(+)/p16(-) and HPV(-)/p16(-) HNSCC had the shortest survival. With current therapeutic strategies, survival of patients with HNSCC is better if associated with HPV(+)/p16(+) or HPV(-)/p16(+). Clinical trials are needed to confirm the distinct survival pattern and to investigate possible differences in survival for HPV(+)/p16(-) and HPV(-)/p16(+) HNSCC. To further differentiate p16(+) HNSCC, HPV testing may be advisable.

    The International Germ Cell Consensus (IGCC) Classification distinguishes patients with non-seminomatous germ cell tumours (NSGCT) with a good, intermediate or poor prognosis, with a reported 5-year overall survival of 92%, 80% and 48%, respectively. Since the IGCC classification was based on patients treated between 1975 and 1990, we aimed to investigate whether survival has improved for more recently treated patients. We did a systematic search of the literature and included studies on survival of patients with NSGCT, treated after 1989 and classified according to the IGCC classification. Survival estimates of selected studies were pooled using meta-analytic techniques. We included 10 papers, describing 1775 patients with NSGCT with good (n = 1087), intermediate (n = 232), or poor (n = 456) prognosis. Pooled 5-year survival estimates were 94%, 83% and 71%, respectively. Since the publication of the IGCC classification, there was a small increase in survival for good and intermediate prognosis patients, and a large increase in survival for patients with a poor prognosis. This increase is most likely due to both more effective treatment strategies and more experience in treating NSGCT patients.

    Glioblastoma is not only the most common primary brain tumor, but also the most aggressive. Currently, the most effective treatment of surgery, chemotherapy and radiation therapy allows for a modest median survival of 15 months. Here, we report a case of a 57-year-old male with histologically confirmed glioblastoma with unfavorable prognostic characteristics (poor performance status and persistent neurological symptoms after surgery), whose expected 5-year survival is 0%. Further genetic analysis offered a mixed prognostic picture with positive methylation of 0-6-methylguinine-DNA (deoxyribonucleic acid) methyltransferase (MGMT; favorable prognosis) and wild-type isocitrate dehydrogenase 1 (IDH-1; unfavorable prognosis). Remarkably, the patient showed a progression-free survival of 5.5 years and a total survival of 6.5 years. In the context of recently published literature, the authors hypothesize that the patient’s use of the antipsychotic medication risperidone may have had a potential antitumor effect. Risperidone antagonizes the dopamine-2 receptor and the serotonin-7 receptor, both of which have been individually implicated in the growth and progression of glioblastoma. To the authors’ knowledge, this is the first clinical case in the literature to explore this association. PMID:27800031

    Summary Background Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control. Methods Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15–99 years) and 75 000 children (age 0–14 years) diagnosed with cancer during 1995–2009 and followed up to Dec 31, 2009, or later. We looked at cancers of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary, and prostate in adults, and adult and childhood leukaemia. Standardised quality control procedures were applied; errors were corrected by the registry concerned. We estimated 5-year net survival, adjusted for background mortality in every country or region by age (single year), sex, and calendar year, and by race or ethnic origin in some countries. Estimates were age-standardised with the International Cancer Survival Standard weights. Findings 5-year survival from colon, rectal, and breast cancers has increased steadily in most developed countries. For patients diagnosed during 2005–09, survival for colon and rectal cancer reached 60% or more in 22 countries around the world; for breast cancer, 5-year survival rose to 85% or higher in 17 countries worldwide. Liver and lung cancer remain lethal in all nations: for both cancers, 5-year survival is below 20% everywhere in Europe, in the range 15–19% in North America, and as low as 7–9% in Mongolia and Thailand. Striking rises in 5-year survival from prostate cancer have occurred in many countries: survival rose by 10–20% between 1995–99 and 2005–09 in 22 countries in South America, Asia, and Europe, but survival still varies widely around the world, from less than 60% in Bulgaria and Thailand to 95% or more in Brazil, Puerto Rico, and the USA.

    Mutations of the isocitrate dehydrogenase (IDH) 1 and 2 genes occur in ~80% of lower-grade (WHO grade II and grade III) gliomas. Mutant IDH produces (R)-2-hydroxyglutarate, which induces DNA hypermethylation and presumably drives tumorigenesis. Interestingly, IDH mutations are associated with improved survival in glioma patients, but the underlying mechanism for the difference in survival remains unclear. Through comparative analyses of 286 cases of IDH-wildtype and IDH-mutant lower-grade glioma from a TCGA data set, we report that IDH-mutant gliomas have increased expression of tumor-suppressor genes (NF1, PTEN, and PIK3R1) and decreased expression of oncogenes(AKT2, ARAF, ERBB2, FGFR3, and PDGFRB) and glioma progression genes (FOXM1, IGFBP2, and WWTR1) compared with IDH-wildtype gliomas. Furthermore, each of these genes is prognostic in overall gliomas; however, within the IDH-mutant group, none remains prognostic except IGFBP2 (encodinginsulin-like growth factor binding protein 2). Through validation in an independent cohort, we show that patients with low IGFBP2 expressiondisplay a clear advantage in overall and disease-free survival, whereas those with high IGFBP2 expressionhave worse median survival than IDH-wildtype patients. These observations hold true across different histological and molecular subtypes of lower-grade glioma. We propose therefore that an unexpected biological consequence of IDH mutations in glioma is to ameliorate patient survival by promoting tumor-suppressor signaling while inhibiting that of oncogenes, particularly IGFBP2.

    Nutritional factors and dialysis adequacy are associated with outcome in hemodialyzed patients, but their relative contribution remains controversial, particularly when dialysis adequacy complies with current recommendations (Kt/V >1.2). Survival, clinical, and nutritional data from a cohort of prevalent 1,610 patients treated by hemodialysis in 20 centers in France have been collected over a 2.5-year period, from January 1996 to July 1998. Data including age, sex, cause of end-stage renal disease (ESRD), clinical outcome, time on dialysis, body mass index (BMI), blood levels of midweek predialysis albumin, prealbumin, and bicarbonate were analyzed. Normalized protein catabolic rate (nPCR), dialysis adequacy parameters, and estimation of lean body mass (LBM) from creatinine generation were computed from pre- and postdialysis urea and creatinine levels. The characteristics of the patients were as follows: age 59.6 +/- 16.5 years, 58.8% males, 11% of diabetics, time on dialysis 63.2 +/- 64.5 m. Weekly dialysis time was 12.18 +/- 1.78 hrs, Kt/V 1.34 +/- 0.34, nPCR 1.10 +/- 0.35 g/kg body weight/day. Albumin concentration was 39.4 +/- 5.3 g/L, prealbumin was 0.33 +/- 0.09 g/L, BMI was 23.0 +/- 4.5 kg/m(2). Overall survival was 89.7% +/- 0.8% and 78.4% +/- 1.1% after 1 and 2 years. In the Cox proportional hazard model, survival was significantly influenced by age, the presence of diabetes, and by concentrations of albumin and prealbumin, but not by other variables, including Kt/V and urea reduction ratio. These results indicate that nutritional protein concentrations were predictive of dialysis outcome, whereas variables reflecting actual body composition and dialysis dose were not. Furthermore, in this well-dialyzed population, dialysis adequacy had no influence on survival. In conclusion, when adequacy targets are met in hemodialyzed patients, survival is mainly dependent on age and nutritional status. Efforts should be focused on the most efficient ways to maintain

    Objective To gather input regarding the presentation, content, and understanding of survival and support information for Prognostigram, a computer-based program that uses standard cancer registry data elements to present individualized survival estimates. Study Design Cross-sectional survey research Methods Two groups of patients (total n=40) and one group of physicians (n=5) were interviewed. The patient groups were interviewed to assess baseline patient numeracy and health literacy and patient desire for prognostic information. The first group (n=20) was introduced to generalized survival curves in a paper booklet. The second group (n=20) was introduced to individualized survival curves from Prognostigram on the computer. Both patient groups were queried about the survival curves. The physicians were asked their opinions on sharing prognostic information with patients. Results Numeracy assessments indicated that the patients are able to understand concepts and statistics presented by Prognostigram. According to the patient interviews, the Internet is the most frequent source for survival statistics. Of the 40 patient participants, 39 reported survival statistics as being “Somewhat” or “Very” useful to cancer patients. All five physicians believed survival statistics were useful to patients and physicians and noted accurate and understandable survival statistics are fundamental to facilitate discussions with patients regarding prognosis and expectations. Conclusion Formative research indicates that cancer patients and their families actively seek survival statistics on their own. All patients indicated strong interest in Prognostigram, which is a software tool designed to produce individualized survival statistics to oncologists and cancer patients in a user-friendly manner.

    OBJECTIVES Pulmonary invasive fungal infections (IFIs) are associated with high mortality in patients being treated for haematological malignancy. There is limited understanding of the role for surgical lung resection and outcomes in this patient population. METHODS This is a retrospective cohort of 50 immunocompromised patients who underwent lung resection for IFI. Patient charts were reviewed for details on primary malignancy and treatment course, presentation and work-up of IFI, reasons for surgery, type of resection and outcomes including postoperative complications, mortality, disease relapse and survival. Analysis was also performed on two subgroups based on year of surgery from 1990–2000 and 2001–2014. RESULTS The median age was 39 years (range: 5–64 years). Forty-seven patients (94%) had haematological malignancies and 38 (76%) underwent haematopoietic stem cell transplantation (HSCT). Surgical indications included haemoptysis, antifungal therapy failure and need for eradication before HSCT. The most common pathogen was Aspergillus in 34 patients (74%). Wedge resections were performed in 32 patients (64%), lobectomy in 9 (18%), segmentectomy in 2 (4%) and some combination of the 3 in 7 (14%) for locally extensive, multifocal disease. There were 9 (18%) minor and 14 (28%) major postoperative complications. Postoperative mortality at 30 days was 12% (n = 6). Acute respiratory distress syndrome was the most common cause of postoperative death. Overall 5-year survival was 19%. Patients who had surgery in the early period had a median survival of 24 months compared with 5 months for those who had surgery before 2001 (P = 0.046). At the time of death, 15 patients (30%) had probable or proven recurrent IFI. Causes of death were predominantly related to refractory malignancy, fungal lung disease or complications of graft versus host disease (GVHD). Patients who had positive preoperative bronchoscopy cultures had a trend towards worse survival compared with

    Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related death in the United States. The five-year survival rate for all stages is approximately 6%, and approximately 2% when presenting with distant disease.1 Only 10-20% of all patients present with resectable disease, but recurrence rates are high with only 5 to 15% remaining free of disease at 5 years. At this time, we are unable to distinguish between resectable PDAC patients with occult metastatic disease from those with potentially curable disease. Early classification of these tumor types may eventually lead to changes in initial management including the use of neoadjuvant chemotherapy or radiation, or in the choice of postoperative adjuvant treatments. Texture analysis is an emerging methodology in oncologic imaging for quantitatively assessing tumor heterogeneity that could potentially aid in the stratification of these patients. The present study derives several texture-based features from CT images of PDAC patients, acquired prior to neoadjuvant chemotherapy, and analyzes their performance, individually as well as in combination, as prognostic markers. A fuzzy minimum redundancy maximum relevance method with leave-one-image-out technique is included to select discriminating features from the set of extracted features. With a naive Bayes classifier, the proposed method predicts the 5-year overall survival of PDAC patients prior to neoadjuvant therapy and achieves the best results in terms of the area under the receiver operating characteristic curve of 0:858 and accuracy of 83:0% with four-fold cross-validation techniques.

    Purpose: Myxofibrosarcoma (MFS) is a rare sarcoma with a predilection for multiple local recurrences (LR), for which optimal treatment has not been defined. We reviewed our experience to determine the impact of surgery and radiation therapy (RT) on pattern of recurrence, limb salvage, and overall survival (OS). Methods and Materials: Between 1995 and 2005, 36 patients with localized intermediate- or high-grade MFS were treated at our institution. Data on clinicopathologic features, treatments, and patient outcomes were reviewed and analyzed. Results: Median age was 72.5 years (range, 42-96 years). Median tumor size was 7.5 cm, and 34 tumors (94%) were high grade. All patients underwent surgery at our institution, including re-resections in 20 patients (56%) after initial surgery elsewhere. Margins were microscopically positive in 9 patients (25%). RT was given to 28 patients (78%) pre - and/or postoperatively. After a median follow-up of 3.5 years (range, 0.4-12.4 years), 11 patients (31%) developed LR. There were no significant predictors for LR on univariate analysis, including margin status or use of RT. Limb salvage was ultimately achieved in only 5 of 11 LRs (45%) because of multiple subsequent LRs. Distant recurrence (DR) occurred in 6 patients (17%). Median and 4-year OS were 96 months and 65%, respectively. Seven patients (19%) died of tumor-related causes, 6 of whom had DRs. On univariate analysis, tumor size was associated with OS. Conclusions: Despite aggressive surgery and RT, intermediate- and high-grade MFS are associated with a high rate of LR that adversely affects limb preservation. More aggressive local treatment strategies are necessary.

    Abstract Gastric cancer remains the second most common cancer in Korea; however, its mortality has decreased due to earlier diagnosis. In Korea, screening endoscopy has been performed nationwide since 1999. The aim of this study was to elucidate the benefit of screening endoscopy on actual survival in gastric cancer patients and to determine the optimal interval of screening endoscopy. We analyzed 1651 patients diagnosed with gastric adenocarcinoma who underwent surgical treatment between June 2008 and December 2014. Patients were divided into 4 groups according to the interval of screening endoscopy prior to their gastric cancer diagnosis. (Group I = within 1 year, Group II = >1 but <2 years, Group III = more than 2 years, Group IV = no prior endoscopic examination). Patient demographics, clinicopathologic characteristics, and postoperative surgical outcomes including overall survival were compared. The 5-year gastric cancer-specific survival rates of groups I and II were significantly higher than groups III and IV (90.9% vs 85.4%, P = 0.002, respectively). Multivariate analysis showed that screening interval was an independent factor for the diagnosis of advanced gastric cancer. The risk of advanced gastric cancer decreased in group I (odds ratio: 0.515, 95% confidence interval [CI] 0.369–0.719; P < 0.001) and group II (odds ratio: 0.678, 95% CI 0.517–0.889, P = 0.005). Screening endoscopy was helpful in increasing the survival of gastric cancer patients. A 2-year endoscopic screening interval is suitable to detect early-stage gastric cancer. PMID:27930534

    Maintenance dialysis is associated with reduced survival when compared with the general population. In Libya, information about outcomes on dialysis is scarce. This study, therefore, aimed to provide the first comprehensive analysis of survival in Libyan dialysis patients. This prospective multicenter study included all patients in Libya who had been receiving dialysis for >90 days in June 2009. Sociodemographic and clinical data were collected upon enrollment and survival status after 1 year was determined. Two thousand two hundred seventy-three patients in 38 dialysis centers were followed up for 1 year. The majority were receiving hemodialysis (98.8%). Sixty-seven patients were censored due to renal transplantation, and 46 patients were lost to follow-up. Thus, 2159 patients were followed up for 1 year. Four hundred fifty-eight deaths occurred, (crude annual mortality rate of 21.2%). Of these, 31% were due to ischemic heart disease, 16% cerebrovascular accidents, and 16% due to infection. Annual mortality rate was 0% to 70% in different dialysis centers. Best survival was in age group 25 to 34 years. Binary logistic regression analysis identified age at onset of dialysis, physical dependency, diabetes, and predialysis urea as independent determinants of increased mortality. Patients receiving dialysis in Libya have a crude 1-year mortality rate similar to most developed countries, but the mean age of the dialysis population is much lower, and this outcome is thus relatively poor. As in most countries, cardiovascular disease and infection were the most common causes of death. Variation in mortality rates between different centers suggests that survival could be improved by promoting standardization of best practice.

    Paraquat concentration-time data have been used to predict the clinical outcome following ingestion. However, these studies have included only small populations, although paraquat poisoning has a very high mortality rate. The purpose of this study was to develop a simple and reliable model to predict survival according to the time interval post-ingestion in patients with acute paraquat poisoning. Data were retrospectively collected for patients who were admitted with paraquat poisoning to Soonchunhyang University Choenan Hospital between January 2005 and December 2012. Plasma paraquat levels were measured using high-performance liquid chromatography. To validate the model we developed, we used external data from 788 subjects admitted to the Presbyterian Medical Center, Jeonju, Korea, between January 2007 and December 2012. Two thousand one hundred thirty six patients were included in this study. The overall survival rate was 44% (939/2136). The probability of survival for any specified time and concentration could be predicted as (exp(logit))/(1+exp(logit)), where logit = 1.3544+[-3.4688 × log10(plasma paraquat μg/M[Formula: see text])]+[-2.3169 × log10(hours since ingestion)]. The external validation study showed that our model was highly accurate for the prediction of survival (C statics 0.964; 95% CI [0.952-0.975]). We have developed a model that is effective for predicting survival after paraquat intoxication.

  11. Nutritional status, psychological issues and survival in hemodialysis patients.

    There is a high prevalence of protein-energy malnutrition in the end-stage renal disease population. There are a number of causes of malnutrition in hemodialysis patients, which can often be directly linked to the uremic state. Laboratory measures including albumin, prealbumin, and serum cholesterol, as well as anthropometric measures, have been used to assess malnutrition in this patient population. There is, however, no single accepted measure of malnutrition in patients with chronic kidney disease. Failure to achieve adequate nutritional goals may lead to protein-energy malnutrition, which has been linked to decreased survival. Several studies have also shown a direct association between psychosocial variables, including depression, and the nutritional status of hemodialysis patients, in particular the serum albumin concentration. Interventions such as oral nutritional supplements or intradialytic parenteral nutrition may be necessary to improve nutritional status if conservative measures such as nutritional counseling and regular dietician follow-up fail to produce the changes needed to sustain health. In addition, given the potential link between psychological conditions, such as depression, and overall nutritional status, interventions designed to screen for and treat psychiatric disorders may lead to improvements in nutritional status and therefore increased survival rates of patients with end-stage renal disease treated with hemodialysis. Further study is needed to evaluate the association between depression, malnutrition, and survival in patients with chronic kidney disease.

    Myelodysplastic syndromes (MDS) are emerging disorders of the elderly with an increasing burden on healthcare systems. He we report on the first population-based, epidemiological analysis of patients diagnosed with MDS in Switzerland between 2001 and 2012. The aim of this study was to characterize the extent and limitations of currently available population-based, epidemiological data and formulate recommendations for future health services research. The investigated outcomes comprised trends of annual case frequency, classification of morphological subtypes, incidence, mortality and survival. Annual case frequency increased by 20% (from 263 to 315 cases per year), whereas age-standardized incidence-/mortality-rates remained stable (2.5/1.1 per 100'000 person-years). This observation reflects population growth as well as higher diagnostic awareness and not an increase of age-specific risk. However, it will inevitably influence the future prevalence of MDS and the impact on healthcare systems. Reporting of classification in MDS subtypes was poor with modest improvement from 20% to 39% and increased awareness for mainly higher-risk diseases. Relative survival for all patients at 5-years (RS) ranged between 37 and 40%. Significant better RS was found for younger compared to older higher-risk MDS patients (48% vs. 17%), reflecting the effect of allogeneic hematopoietic stem-cell transplantation. However, no survival advantage was found in elderly patients after introduction of hypomethylating agents as standard for care in this patient group. Our data is in line with results from other MDS and cancer registries. It allows formulating recommendations for future collaborative health services research on MDS patients with national and international partners.

    Background and Objectives Predictive factors of mortality in acute coronary syndrome (ACS) patients with left ventricular dysfunction were analyzed during 5-year clinical follow-up after percutaneous coronary intervention (PCI). Subjects and Methods A total of 329 ACS consecutive patients (64.6±11.3 years, 227 males) who underwent PCI from January 2001 to March 2006 were followed for 5 years. All patients had lower than 40% of left ventricular ejection fraction (LVEF). Patients were divided into Group I (survived longer than 5-years: n=130, 101 males) and Group II (survived shorter than 5 years: n=199, 126 males). Results The cumulative survival rate was 88.0% at 1 month, 78.0% at 6 months, 75.0% at 1 year, 67.0% at 2 years, 62.0% at 3 years, 57.0% at 4 years and 40% at 5-years. Group II was older (61.6±11.2 years vs. 66.4±11.4 years, p<0.001), and showed higher prevalence of female gender (28.4% vs. 36.7%, p=0.006) and lower LVEF (35.3±5.2 vs. 33.6±5.6) than Group I. The independent predictors for mortality were LVEF <30% {odds ratio (OR)=1.793, 95% confidence interval (CI): 1.234-2.452, p=0.002}, serum creatinine >3.0 mg/dL (OR=2.455, 95% CI: 1.306-4.614, p=0.005), older than 65 years (OR=1.594, 95% CI: 1.152-2.206, p=0.005), and female gender (OR=1.524, 95% CI: 1.090-2.130, p=0.014). Conclusion Five-year survival rate was 40% in ACS patients with left ventricular dysfunction, and the predictors for mortality were low LVEF, high serum creatinine, old age, and female gender.

    Mutations of the isocitrate dehydrogenase (IDH) 1 and 2 genes occur in ~80% of lower-grade (WHO grade II and grade III) gliomas. Mutant IDH produces (R)-2-hydroxyglutarate, which induces DNA hypermethylation and presumably drives tumorigenesis. Interestingly, IDH mutations are associated with improved survival in glioma patients, but the underlying mechanism for the difference in survival remains unclear. Through comparative analyses of 286 cases of IDH-wildtype and IDH-mutant lower-grade glioma from a TCGA data set, we report that IDH-mutant gliomas have increased expression of tumor-suppressor genes (NF1, PTEN, and PIK3R1) and decreased expression of oncogenes(AKT2, ARAF, ERBB2, FGFR3, and PDGFRB) and glioma progression genes (FOXM1, IGFBP2, and WWTR1) compared with IDH-wildtype gliomas. Furthermore, each of these genes is prognostic in overall gliomas; however, within the IDH-mutant group, none remains prognostic except IGFBP2 (encodinginsulin-like growth factor binding protein 2). Through validation in an independent cohort, we show that patients with low IGFBP2 expressiondisplay a clear advantage in overall and disease-free survival, whereas those with high IGFBP2 expressionhave worse median survival than IDH-wildtype patients. These observations hold true across different histological and molecular subtypes of lower-grade glioma. We propose therefore that an unexpected biological consequence of IDH mutations in glioma is to ameliorate patient survival by promoting tumor-suppressor signaling while inhibiting that of oncogenes, particularly IGFBP2.

    Intensity-modulated radiotherapy (IMRT) has replaced the conventional radiotherapy (2D-RT) and improved clinical efficacy in Nasopharyngeal Carcinoma (NPC) patients. In the present study, we retrospectively analyzed the clinical characteristics of patients with NPC treated with IMRT to assess the long-term survival outcomes and failure patterns. Of the 527 patients, One hundred and twenty-one patients experienced treatment failure, 86 patients developed distant metastases, and 12 patients developed a second primary tumor. The local and regional recurrence rates were 31.4% and 14.0%, respectively. The 5-year overall survival (OS), progression-free survival (PFS), local recurrence-free survival (LRFS), regional relapse-free survival (RRFS), and distant metastatic relapse-free survival (DMFS) rates were 80.9%, 75.6%, 91.7%, 96.2%, and 83.0%, respectively. The 5-year LRFS rates of Stage T1-4 patients were 100.0%, 93.1%, 92.0%, and 85.8%, respectively. The 5-year DMFS rates of Stage N0-3 patients were 95.0%, 86.1%, 79.5%, and 67.2%, respectively. Multivariate analysis showed age and T-stage were independent predictors of OS, T-stage was an independent predictor of LRFS, and age and N-stage were independent predictors of PFS and DMFS. In summary, the improved treatment results with IMRT are primarily due to the achievement of a higher local tumor control rate and OS in NPC patients. However, distant metastasis was the most commonly observed failure pattern after treatment. These results provide deep insights about the value of IMRT in the treatment and prognosis of NPC patients.

    Purpose: To evaluate the clinical outcome of salvage treatment for patients with relapsed natural killer (NK)/T-cell lymphoma, nasal type. Methods and Materials: Forty-four patients who had achieved complete response during initial treatment and experienced histologically proven relapse were reviewed. Twenty-nine of them received salvage treatment with radiotherapy (RT) alone (n = 7), chemotherapy (CT) alone (n = 10), or both RT and CT (n = 12); the other 15 patients received best supportive care alone. Results: The estimated 5-year overall survival (OS) rate for patients with or without salvage treatment was 37.8% vs. 0 (p < 0.0001), respectively. Salvage CT did not improve survival of relapsed Stage IE and IIE patients. Among relapsed Stage IIIE and IVE patients who received salvage treatment, RT developed significantly better survival when compared with that of non-RT (1-year OS, 62.5% vs. 0, p = 0.006). Relapsed Ann Arbor stage and receiving salvage treatment were found to be significant factors influencing OS at both univariate and multivariate levels. Conclusions: Salvage treatment improved survival in patients with relapsed NK/T-cell lymphoma, nasal type. Salvage RT may play an important role in salvage treatment of relapsed extranodal NK/T-cell lymphoma.

    Purpose: To analyze outcomes and factors predictive for recurrence and survival in patients with operable esophageal carcinoma who achieved pathologic complete response (PCR) or microscopic residual disease (MRD) after preoperative chemoradiotherapy (CRT). Materials and Methods: Outcomes were assessed in 70 patients with locally advanced esophageal cancer who achieved pathologic major response (53 with PCR and 17 with MRD) after preoperative CRT. Results: At a median follow-up of 38.6 months for surviving patients, 17 of 70 patients (24.3%) experienced disease recurrence and 31 (44.3%) died. Clinical stage (II vs III; p = 0.013) and pathologic response (PCR vs. MRD; p = 0.014) were independent predictors of disease recurrence. Median overall survival (OS) was 99.6 months (95% CI, 44.1-155.1 months) and the 5-year OS rate was 57%. Median recurrence-free survival (RFS) was 71.5 months (95% CI, 39.5-103.6 months) and the 5-year RFS rate was 51.3%. Median OS of patients with Stage II and Stage III disease was 108.8 months and 39.9 months, respectively, and the 5-year OS rates were 68.2% and 27.0%, respectively (p = 0.0003). In a subgroup of patients with PCR, median OS and RFS were also significantly different according to clinical stage. Multivariate analysis showed that clinical stage was an independent predictor of RFS (p = 0.01) and OS (p = 0.008). Conclusions: Even though patients achieved major response after preoperative CRT, pretreatment clinical stage is an important prognostic marker for recurrence and survival. Patients with MRD have an increased recurrence risk but similar survival compared with patients achieved PCR.

    Purpose: A nomogram is a predictive statistical model that generates the continuous probability of a clinical event such as death or recurrence. The aim of the study was to construct a nomogram to predict 5-year overall survival after postoperative radiation therapy for stage IB to IIA cervical cancer. Methods and Materials: The clinical data from 1702 patients with early-stage cervical cancer, treated at 10 participating hospitals from 1990 to 2011, were reviewed to develop a prediction nomogram based on the Cox proportional hazards model. Demographic, clinical, and pathologic variables were included and analyzed to formulate the nomogram. The discrimination and calibration power of the model was measured using a concordance index (c-index) and calibration curve. Results: The median follow-up period for surviving patients was 75.6 months, and the 5-year overall survival probability was 87.1%. The final model was constructed using the following variables: age, number of positive pelvic lymph nodes, parametrial invasion, lymphovascular invasion, and the use of concurrent chemotherapy. The nomogram predicted the 5-year overall survival with a c-index of 0.69, which was superior to the predictive power of the International Federation of Gynecology and Obstetrics (FIGO) staging system (c-index of 0.54). Conclusions: A survival-predicting nomogram that offers an accurate level of prediction and discrimination was developed based on a large multi-center study. The model may be more useful than the FIGO staging system for counseling individual patients regarding prognosis.

    Background: The preventive role of non-steroid anti-inflammatory drugs (NSAIDs) and aspirin, in particular, on colorectal cancer is well established. More recently, it has been suggested that aspirin may also have a therapeutic role. Aim of the present observational population-based study was to assess the therapeutic effect on overall survival of aspirin/NSAIDs as adjuvant treatment used after the diagnosis of colorectal cancer patients. Methods: Data concerning prescriptions were obtained from PHARMO record linkage systems and all patients diagnosed with colorectal cancer (1998–2007) were selected from the Eindhoven Cancer Registry (population-based cancer registry). Aspirin/NSAID use was classified as none, prediagnosis and postdiagnosis and only postdiagnosis. Patients were defined as non-user of aspirin/NSAIDs from the date of diagnosis of the colorectal cancer to the date of first use of aspirin or NSAIDs and user from first use to the end of follow-up. Poisson regression was performed with user status as time-varying exposure. Results: In total, 1176 (26%) patients were non-users, 2086 (47%) were prediagnosis and postdiagnosis users and 1219 (27%) were only postdiagnosis users (total n=4481). Compared with non-users, a survival gain was observed for aspirin users; the adjusted rate ratio (RR) was 0.77 (95% confidence interval (CI) 0.63–0.95; P=0.015). Stratified for colon and rectal, the survival gain was only present in colon cancer (adjusted RR 0.65 (95%CI 0.50–0.84; P=0.001)). For frequent users survival gain was larger (adjusted RR 0.61 (95%CI 0.46–0.81; P=0.001). In rectal cancer, aspirin use was not associated with survival (adjusted RR 1.10 (95%CI 0.79–1.54; P=0.6). The NSAIDs use was associated with decreased survival (adjusted RR 1.93 (95%CI 1.70–2.20; P<0.001). Conclusion: Aspirin use initiated or continued after diagnosis of colon cancer is associated with a lower risk of overall mortality. These findings strongly support initiation of

    Maple syrup urine disease is a rare metabolic disorder caused by mutations in the branched-chain α-keto acid dehydrogenase complex gene. Patients generally present early in life with a toxic encephalopathy because of the accumulation of the branched-chain amino acids leucine, isoleucine, and valine and the corresponding ketoacids. Movement disorders in maple syrup urine disease have typically been described during decompensation episodes or at presentation in the context of a toxic encephalopathy, with complete resolution after appropriate dietary treatment. Movement disorders in patients surviving childhood are not well documented. We assessed 17 adult patients with maple syrup urine disease (mean age, 27.5 years) with a special focus on movement disorders. Twelve (70.6%) had a movement disorder on clinical examination, mainly tremor and dystonia or a combination of both. Parkinsonism and simple motor tics were also observed. Pyramidal signs were present in 11 patients (64.7%), and a spastic-dystonic gait was observed in 6 patients (35.2%). In summary, movement disorders are common in treated adult patients with maple syrup urine disease, and careful neurological examination is advisable to identify those who may benefit from specific therapy. © 2011 Movement Disorder Society.

    Purpose: To correlate the prechemoradiotherapy (CRT) and post-CRT metabolic tumor volume (MTV) on positron emission tomography (PET) scanning with the pathologic response and survival in patients receiving preoperative CRT for esophageal cancer. Materials and Methods: The medical records of 37 patients with histologically confirmed Stage I-IVA esophageal cancer treated with CRT with or without surgical resection were reviewed. Of the 37 patients, 21 received preoperative CRT (57%) and 16 received definitive CRT (43%). All patients had a pre-CRT and 32 had a post-CRT PET scan. The MTV was measured on the pre-CRT PET and post-CRT PET scan, respectively, using a minimum standardized uptake value (SUV) threshold x, where x = 2, 2.5, 3, or the SUV maximum Multiplication-Sign 50%. The total glycolytic activity (TGA{sub x}) was defined as the mean SUV Multiplication-Sign MTV{sub x}. The MTV ratio was defined as the pre-CRT PET MTV/post-CRT MTV. The SUV ratio was defined similarly. A single pathologist scored the pathologic response using a tumor regression grade (TRG) scale. Results: The median follow-up was 1.5 years (range, 0.4-4.9). No significant correlation was found between any parameters on the pre-CRT PET scan and the TRG or overall survival (OS). Multiple post-CRT MTV values and post-TGA values correlated with the TRG and OS; however, the MTV{sub 2.5Post} and TGA{sub 2.5Post} had the greatest correlation. The MTV{sub 2} ratio correlated with OS. The maximum SUV on either the pre-CRT and post-CRT PET scans or the maximum SUV ratio did not correlate with the TRG or OS. Patients treated preoperatively had survival similar compared with those treated definitively with a good PET response (p = 0.97) and significantly better than that of patients treated definitively with a poor PET response (p < 0.0001). Conclusion: The maximum SUV was not a predictive or prognostic parameter. The MTV{sub 2.5} and TGA{sub 2.5} were useful markers for predicting the response and

    We present the case of a 75-year-old woman with haemochromatosis who developed a 5-year-long right ulnar non-union after a shortening osteotomy to correct a malunited Colles' fracture. Standard surgical treatment for ulnar non-unions was attempted on 19 March 2008 and again on 20 April 2009, but the non-union persisted on 8 May 2012, as confirmed by CT scan. Vascular bone grafting and refixation was then considered, but the patient declined this extensive operation, instead choosing to try non-invasive low-intensity pulsed ultrasound treatment with an Exogen device. Just 4 months later, complete union as confirmed by CT scan was achieved. This is the first case demonstrating the efficacy of ultrasound treatment for long-standing non-unions resistant to surgery in patients with haemochromatosis, a disorder where iron deposition can provide suboptimal circumstances for bone healing. Our finding suggests that low-intensity pulsed ultrasound devices could be used as a first-line treatment for stable non-unions instead of revision surgery.

    Background and purpose Clinical results of total knee replacement (TKR) are inferior in younger patients, mainly due to aseptic loosening. Coating of components with trabecular metal (TM) is a new way of enhancing fixation to bone. We have previously reported stabilization of TM tibial components at 2 years. We now report the 5-year follow-up of these patients, including RSA of their TM tibial components. Patients and methods 22 patients (26 knees) received an uncemented TM cruciate-retaining tibial component and 19 patients (21 knees) a cemented NexGen Option cruciate-retaining tibial component. Follow-up with RSA, and clinical and radiographic examinations were done at 5 years. In bilaterally operated patients, the statistical analyses included only the first-operated knee. Results Both groups had most migration within the first 3 months, the TM implants to a greater extent than the cemented implants. After 3 months, both groups stabilized and remained stable up to the 5-year follow-up. Interpretation After a high initial degree of migration, the TM tibia stabilized. This stabilization lasted for at least 5 years, which suggests a good long-term performance regarding fixation. The cemented NexGen CR tibial components showed some migration in the first 3 months and then stabilized up to the 5-year follow-up. This has not been reported previously. PMID:23992142

    Objectives: To explore periimplant health (and relation with periodontal status) 4-5 years after implant insertion. Study Design: A practice-based dental research network multicentre study was performed in 11 Spanish centres. The first patient/month with implant insertion in 2004 was considered. Per patient four teeth (one per quadrant) showing the highest bone loss in the 2004 panoramic X-ray were selected for periodontal status assessment. Bone losses in implants were calculated as the differences between 2004 and 2009 bone levels in radiographs. Results: A total of 117 patients were included. Of the 408 teeth considered, 73 (17.9%) were lost in 2009 (losing risk: >50% for bone losses ≥7mm). A total of 295 implants were reviewed. Eight of 117 (6.8%) patients had lost implants (13 of 295 implants installed; 4.4%). Implant loss rate (quadrant status) was 1.4% (edentulous), 3.6% (preserved teeth), and 11.1% (lost teeth) (p=0.037). The percentage of implant loss significantly (p<0.001) increased when the medial/distal bone loss was ≥3 mm. The highest (p≤0.001) pocket depths were found in teeth with ≥5mm and implants with ≥3mm bone losses, with similar mean values (≥4mm), associated with higher rates of plaque index and bleeding by probing. Conclusions: The significant bi-directional relation between plaque and bone loss, and between each of these two parameters/signs and pocket depths or bleeding (both in teeth and implants, and between them) together with the higher percentage of implants lost when the bone loss of the associated teeth was ≥3 mm suggest that the patient’s periodontal status is a critical issue in predicting implant health/lesion.

    IMPORTANCE The natural history of patients with newly diagnosed high-risk nonmetastatic (M0) prostate cancer receiving hormone therapy (HT) either alone or with standard-of-care radiotherapy (RT) is not well documented. Furthermore, no clinical trial has assessed the role of RT in patients with node-positive (N+) M0 disease. The STAMPEDE Trial includes such individuals, allowing an exploratory multivariate analysis of the impact of radical RT. OBJECTIVE To describe survival and the impact on failure-free survival of RT by nodal involvement in these patients. DESIGN, SETTING, AND PARTICIPANTS Cohort study using data collected for patients allocated to the control arm (standard-of-care only) of the STAMPEDE Trial between October 5, 2005, and May 1, 2014. Outcomes are presented as hazard ratios (HRs) with 95% CIs derived from adjusted Cox models; survival estimates are reported at 2 and 5 years. Participants were high-risk, hormone-naive patients with newly diagnosed M0 prostate cancer starting long-term HT for the first time. Radiotherapy is encouraged in this group, but mandated for patients with node-negative (N0) M0 disease only since November 2011. EXPOSURES Long-term HT either alone or with RT, as per local standard. Planned RT use was recorded at entry. MAIN OUTCOMES AND MEASURES Failure-free survival (FFS) and overall survival. RESULTS A total of 721 men with newly diagnosed M0 disease were included: median age at entry, 66 (interquartile range [IQR], 61-72) years, median (IQR) prostate-specific antigen level of 43 (18-88) ng/mL. There were 40 deaths (31 owing to prostate cancer) with 17 months’ median follow-up. Two-year survival was 96% (95% CI, 93%-97%) and 2-year FFS, 77% (95% CI, 73%-81%). Median (IQR) FFS was 63 (26 to not reached) months. Time to FFS was worse in patients with N+ disease (HR, 2.02 [95% CI, 1.46-2.81]) than in those with N0 disease. Failure-free survival outcomes favored planned use of RT for patients with both N0M0 (HR, 0.33 [95% CI

    Genes induced in colon cancer provide novel candidate biomarkers of tumor phenotype and aggressiveness. We originally identified KIAA1199 (now officially called CEMIP) as a transcript highly induced in colon cancer: initially designating the transcript as Colon Cancer Secreted Protein 1. We molecularly characterized CEMIP expression both at the mRNA and protein level and found it is a secreted protein induced an average of 54-fold in colon cancer. Knockout of CEMIPreduced the ability of human colon cancer cells to form xenograft tumors in athymic mice. Tumors that did grow had increased deposition of hyaluronan, linking CEMIP participation in hyaluronan degradation to the modulation of tumor phenotype. We find CEMIP mRNA overexpression correlates with poorer patient survival. In stage III only (n = 31) or in combined stage II plus stage III colon cancer cases (n = 73), 5-year overall survival was significantly better (p = 0.004 and p = 0.0003, respectively) among patients with low CEMIP expressing tumors than those with high CEMIP expressing tumors. These results demonstrate that CEMIP directly facilitates colon tumor growth, and high CEMIP expression correlates with poor outcome in stage III and in stages II+III combined cohorts. We present CEMIP as a candidate prognostic marker for colon cancer and a potential therapeutic target.

    Introduction: Very severe head trauma cases, defined as Glasgow Coma Scale (GCS) scores of less than 6, have a higher mortality rate and poorer outcome. The purpose of this study was to recognize factors associated with survival and 6-month favorable outcome of very severe head trauma patients presenting to emergency department. Methods: In this historical cohort study, the authors retrospectively reviewed medical records of head trauma patients who were admitted to the emergency department with post-resuscitation GCS scores of less than 6. Both univariate and multivariate analyses were used to test the association between various parameters with survival and 6-month outcome. Results: 103 cases with the mean age of 39 ± 16.5 years were studied (80% male). The overall survival rate was 41.7% and the rate of 6-month favorable outcome was 28.2%. In multivariate analysis, brisk pupil light reaction on admission and patent basal cistern on brain computed tomography (CT) scan were significant factors associated with both survival (OR 5.20, 95% CI 1.57-17.246, p = 0.007 and OR 3.65, 95% CI 1.22-10.91, p=0.02 respectively) and favorable outcome (OR 4.07, 95% CI 1.35-12.24, p=0.01 and OR 3.54, 95% CI 1.22-10.26, p 0.02), respectively. Conclusion: Based on the results of present study, the survival rate of patients with very severe head trauma (GCS < 6) was 41.7%. The strong predictors of survival and 6-month favorable outcome of these patients were brisk pupillary reactivity and patent cistern on brain CT scan. It seems that very severe head trauma patients still have a reasonable chance to survive and aggressive management should be continued. PMID:28286831

    Limited data exists about the long-term prognosis of patients with acute decompensated heart failure (ADHF) further stratified according to ejection fraction (EF) findings. The primary objective of this population-based observational study was to characterize and compare trends in long-term prognosis after an episode of ADHF across 3 EF strata. Hospital medical records were reviewed for 3,604 residents of the Worcester (MA) metropolitan area who were discharged after ADHF from all 11 medical centers in central Massachusetts during 1995, 2000, 2002, and 2004 and had EF measurements during their index hospitalization. The average age of this population was 75 years, the majority was white, and 44% were men. Approximately 49% of the population had preserved EF HF (HF-PEF) (≥50%), 37% had reduced EF HF (HF-REF) (<40%), and 14% had borderline EF HF (41-49%) (HF-BREF). Patients with HF-PEF experienced higher post discharge survival rates than patients with either HF-REF or HF-BREF at 1, 2, and 5-years after discharge from all central Massachusetts medical centers. While prognosis at 1-year after hospital discharge improved for all patient groups during the years under study, especially for those with HF-REF and HF-PEF, these encouraging trends declined with increasing duration of follow-up. In conclusion, although improvements in 1-year post-discharge survival were observed for patients in each of the 3 EF groups examined to varying degrees, the post-discharge prognosis of all patients with ADHF remains guarded.

    Background Coronary computed tomography angiography (coronary CTA) can prognosticate outcomes in patients without modifiable risk factors over medium term follow-up. This ability was driven by major adverse cardiovascular events (MACE). Objective Determine if coronary CTA could discriminate risk of mortality with longer term follow-up. In addition we sought to determine the long-term relationship to MACE. Methods From 12 centers, 1884 patients undergoing coronary CTA without prior coronary artery disease (CAD) or any modifiable CAD risk factors were identified. The presence of CAD was classified as none (0% stenosis), mild (1% to 49% stenosis) and obstructive (≥50% stenosis severity). The primary endpoint was all-cause mortality and the secondary endpoint was MACE. MACE was defined as the combination of death, nonfatal myocardial infarction, unstable angina, and late target vessel revascularization (>90 days). Results Mean age was 55.6 ± 14.5 years. At mean 5.6 ± 1.3 years follow-up, 145(7.7%) deaths occurred. All-cause mortality demonstrated a dose-response relationship to the severity and number of coronary vessels exhibiting CAD. Increased mortality was observed for >1 segment non-obstructive CAD (hazard ratio [HR]:1.73; 95% confidence interval [CI]: 1.07–2.79; p = 0.025), obstructive 1&2 vessel CAD (HR: 1.70; 95% CI: 1.08–2.71; p = 0.023) and 3-vessel or left main CAD (HR: 2.87; 95% CI: 1.57–5.23; p = 0.001). Both obstructive CAD (HR: 6.63; 95% CI: 3.91–11.26; p < 0.001) and non-obstructive CAD (HR: 2.20; 95% CI: 1.31–3.67; p = 0.003) predicted MACE with increased hazard associated with increasing CAD severity; 5.60% in no CAD, 13.24% in non-obstructive and 36.28% in obstructive CAD, p < 0.001 for trend. Conclusions In individuals being assessed for CAD with no modifiable risk factors, all-cause mortality in the long term (>5 years) was predicted by the presence of more than 1 segment of non-obstructive plaque, obstructive 1- or 2-vessel CAD and 3

    Objective We aimed to evaluate the prognostic and predictive value of the nucleotide excision repair-related gene GTF2H5, which is localized at the 6q24.2-26 deletion previously reported by our group to predict longer survival of high-grade serous ovarian cancer patients. Methods In order to test if protein levels of GTF2H5 are associated with patients' outcome, we performed GTF2H5 immunohistochemical staining in 139 high-grade serous ovarian carcinomas included in tissue microarrays. Upon stratification of cases into high- and low-GTF2H5 staining categories (> and ≤ median staining, respectively) Kaplan-Meier and log-rank test were used to estimate patients’ survival and assess statistical differences. We also evaluated the association of GTF2H5 with survival at the transcriptional level by using the on-line Kaplan-Meier plotter tool, which includes gene expression and survival data of 855 high-grade serous ovarian cancer patients from 13 different datasets. Finally, we determined whether stable short hairpin RNA-mediated GTF2H5 downregulation modulates cisplatin sensitivity in the SKOV3 and COV504 cell lines by using cytotoxicity assays. Results Low expression of GTF2H5 was associated with longer 5-year survival of patients at the protein (hazard ratio [HR], 0.52; 95% CI, 0.29 to 0.93; p=0.024) and transcriptional level (HR, 0.80; 95% CI, 0.65 to 0.97; p=0.023) in high-grade serous ovarian cancer patients. We confirmed the association with 5-year overall survival (HR, 0.55; 95% CI, 0.38 to 0.78; p=0.0007) and also found an association with progression-free survival (HR, 0.72; 95% CI, 0.54 to 0.96; p=0.026) in a homogenous group of 388 high-stage (stages III-IV using the International Federation of Gynecology and Obstetrics staging system), optimally debulked high-grade serous ovarian cancer patients. GTF2H5-silencing induced a decrease of the half maximal inhibitory concentration upon cisplatin treatment in GTF2H5-silenced ovarian cancer cells. Conclusion Low

    This study aimed to construct a nomogram to predict survival of patients with resectable gastric cancer (RGC) based on both clinicopathology characteristics and systemic inflammatory response markers (SIRMs). Of 3,452 RGC patients after D2 gastrectomy at the Sun Yat-sen University Cancer Center, 1058 patients who met the inclusion criterion were analyzed. The patients operated on from January 1, 2005 to December 31, 2009 were assigned to the training set (817 patients) to establish a nomogram, and the rest (241 patients) were selected as validation set. Based on the training set, seven independent risk factors were selected in the nomogram. The calibration curves for probability of 1-year, 3-year and 5-year overall survival (OS) showed satisfactory accordance between nomogram prediction and actual observation. When the metastatic lymph node stage (mLNS) is replaced by metastasis lymph node ratio (mLNR) in validation set, the C-index in predicting OS rise from 0.77 to 0.79, higher than that of 7th American Joint Committee on Cancer 7th (AJCC) staging system (0.70; p<0.001). In conclusions, the proposed nomogram which including mLNR and routine detected SIRMs resulted in optimal survival prediction for RGC patients after D2 gastrectomy. PMID:27121054

    Various serum biomarkers have been developed for predicting head and neck squamous cell carcinoma (HNSCC) prognosis. However, none of them have been proven to be clinically significant. A recent study reported that the ratio of aspartate aminotransaminase (AST) to alanine aminotransaminase (ALT) had a prognostic effect on non-metastatic cancers. This study aimed to examine the effect of the AST/ALT ratio on the survival of patients with HNSCC. Clinical data of 356 patients with locoregionally advanced HNSCC were collected. The effect of the AST/ALT ratio on overall survival was analyzed using a Cox proportional hazard model. Moreover, recursive partitioning analysis (RPA) was used to divide the patients into groups on the basis of the clinical stage and AST/ALT ratio. The prognostic ability of this grouping was validated using an independent data set (N = 167). The AST/ALT ratio ranged from 0.42 to 4.30 (median, 1.42) and was a prognostic factor for overall survival that was independent of age, primary sites, and tumor stage (hazard ratio: 1.36, confidence interval: 1.08−1.68, P = 0.010). RPA divided patients with stage IVA into the following two subgroups: high AST/ALT (≥2.3) and low AST/ALT (<2.3) subgroups. The 5-year survival rate for patients with stage III, stage IVA with a low AST/ALT ratio, stage IVA with a high AST/ALT ratio, and stage IVB were 64.8%, 49.2%, 28.6%, and 33.3%, respectively (p < 0.001). Compared with the low AST/ALT group, the adjusted hazard ratio for death was 2.17 for high AST/ALT group (confidence interval: 1.02–.22 P = 0.045). The AST/ALT ratio was demonstrated to be a prognostic factor of HNSCC. The ratio subdivided patients with stage IVA into low- and high-risk groups. Moreover, intensified treatment for the high-risk group may be considered. PMID:27732629

    Background We aimed to investigate the patterns of failure (locoregional and distant metastasis), associated factors, and treatment outcomes in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT) combined with chemotherapy. Patients and methods From April 2006 to December 2011, 68 nasopharyngeal carcinoma patients were treated with IMRT and chemotherapy at our hospital. Median radiation doses delivered to gross tumor volume and positive neck nodes were 66–70 Gy, 63 Gy to clinical target volume, and 50.4–56 Gy to clinically negative neck. The clinical toxicities, patterns of failures, locoregional control, distant metastasis control, disease-free survival, and overall survival were observed. Results The median follow-up time was 52.2 months (range: 11–87 months). Epstein–Barr virus infection was positive in 63.2% of patients. Overall disease failure developed in 21 patients, of whom 85.8% belonged to stage III/IV disease. Among these, there were seven locoregional recurrences, three regional recurrences with distant metastases, and eleven distant metastases. The median interval from the date of diagnosis to failure was 26.5 months (range: 16–50 months). Six of ten (60%) locoregional recurrences were treated with reirradiation ± concurrent chemotherapy. The 5-year locoregional control, distant metastasis control, disease-free survival, and overall survival rates of whole cohort were 81.1%, 74.3%, 60.1%, and 73.4%, respectively. Cox regression analyses revealed that neoadjuvant chemotherapy, age, and Epstein–Barr virus were independent predictors for disease-free survival. Conclusion Neoadjuvant chemotherapy followed by IMRT with or without chemotherapy improves the long-term survival of Saudi patients with nasopharyngeal carcinoma. Distant metastasis was the main pattern of treatment failure. Neoadjuvant chemotherapy, age, and Epstein–Barr virus status before IMRT were important independent prognostic factors

    Recent oral contraceptive (OC) use is associated with modestly higher breast cancer incidence among younger women, but its impact on survival is unclear. This study examined the relationship between OC use before breast cancer diagnosis and survival. A population-based sample of 1,264 women aged 20 to 54 years with a first primary invasive breast cancer during 1990 to 1992 were followed up for 8 to 10 years. OC and covariate data were obtained by interviews conducted shortly after diagnosis and from medial records. All-cause mortality was ascertained through the National Death Index (n = 292 deaths). Age- and income-adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated by Cox regression methods. All-cause mortality was not associated with ever use of OCs or duration of use. Compared with nonusers, mortality estimates were elevated among women who were using OCs at diagnosis or stopped use in the previous year (HR, 1.57; 95% CI, 0.95-2.61). The HR for use of high-dose estrogen pills within 5 years before diagnosis was double that of nonusers (HR, 2.39; 95% CI, 1.29-4.41) or, if the most recent pill included the progestin levonorgestrel, compared with nonusers (HR, 2.01; 95% CI, 1.03-3.91). Because subgroup estimates were based on small numbers of OC users, these results should be cautiously interpreted. Overall, most aspects of OC use did not seem to influence survival, although there is limited evidence that OC use just before diagnosis, particularly use of some pill types, may negatively impact survival in breast cancer patients aged 20 to 54 years.

    Heart failure (HF) with reduced left ventricular (LV) ejection fraction (HFrEF) is regarded as an independent risk factor for poor outcomes after coronary artery bypass grafting (CABG). However, the impact of HF with preserved EF (HFpEF) still has been unclear. We identified 1,877 patients who received isolated CABG of 15,939 patients who underwent first coronary revascularization enrolled in the CREDO-Kyoto (Coronary REvascularization Demonstrating Outcome Study in Kyoto) Registry Cohort-2. Of them, 1,489 patients had normal LV function (LVEF >50% without a history of HF; Normal group), 236 had HFrEF (LVEF ≤50% with HF), and 152 had HFpEF (LVEF >50% with HF). Preoperative LVEF was the lowest in the HFrEF group (62 ± 12%, 36 ± 9%, and 61 ± 7% for the Normal, HFrEF, and HFpEF groups, respectively; p <0.001). Unadjusted 30-day mortality rate was the highest in the HFrEF group (0.5%, 3.0%, and 0.7%; p = 0.003). However, cumulative incidences of all-cause death at 5-year was the highest in the HFpEF group (14%, 27%, and 32%, respectively; p <0.001). After adjusting confounders, the risk of all-cause death in the HFpEF group was greater than the Normal group (hazard ratio [HR] 1.42; 95% confidence interval [CI] 1.02 to 1.97; p = 0.04). The risk of all-cause death was not different between the HFpEF and the HFrEF groups (HR 0.88; 95% CI 0.61 to 1.29; p = 0.52). In addition, the risks of cardiac death and sudden death in the HFpEF group were greater than the Normal group (HR 2.14, 95% CI 1.32 to 3.49, p = 0.002; and HR 3.60, 95% CI 1.55 to 8.36, p = 0.003, respectively), and the risks of those end points were not different between the HFrEF and the HFpEF groups. Despite low 30-day mortality rate after CABG in patients with HFpEF, HFpEF was associated with high risks of long-term death and cardiovascular events. Patients with HFpEF, as well as HFrEF, should be carefully operated and followed up.

    This study estimates the risk of symptomatic nephrolithiasis within 5 years of newly diagnosed osteoporosis in a Taiwan population. This cohort study consisted of patients with a diagnosis of osteoporosis between Jan. 2003 and Dec. 2005 (N = 1634). Four age- and gender- matched patients for every patient in the study cohort were selected using random sampling as the comparison cohort (N = 6536). All patients were tracked for 5 years from the date of cohort entry to identify whether they developed symptomatic nephrolithiasis. Cox proportional hazard regressions were performed to evaluate the 5-year nephrolithiasis-free survival rates. During the 5-year follow-up period, 60 osteoporosis patients (3.7%) and 165 non- osteoporosis patients (2.5%) developed symptomatic nephrolithiasis. The adjusted HR of symptomatic nephrolithiasis was 1.38 times greater risk for patients with osteoporosis than for the comparison cohort (95% confidence interval (CI) 1.03-1.86; P < .05). Osteoporosis is very likely to be an independent risk factor for subsequent diagnosis of symptomatic nephrolithiasis.

    Liver and pulmonary metastases (PMs) are relatively common in patients with colorectal cancer. The majority of metastases are suitable for surgical resection, and the effectiveness of metastasectomy is usually assessed based on overall survival (OS). Metastasectomy provides a mean 5-year OS rate of approximately 50%, but the results are better in patients with liver metastases compared to those with PMs. Unfortunately, the presence of bilateral or multiple PMs represents a relative contraindication to surgical metastasectomy. Unresectable PMs can be safely treated with percutaneous radiofrequency ablation or radiotherapy, but the reported results vary widely. Several clinical prognostic factors affecting OS after metastasectomy have been reported, such as number of PMs, hilar or mediastinal lymph node involvement, disease-free interval, age and gender, resection margins, size of the metastases, neoadjuvant chemotherapy administration, and histological type of the primary cancer. The accurate evaluation of all clinical prognostic factors, circulating and immunohistochemical markers, and the study of gene mutational status will lead to a more accurate selection of patients scheduled to metastasectomy, with the aim of improving outcome.

    The impact of bone marrow (BM) GD2-positive cells on survival has been evaluated in 145 Italian children with localised neuroblastoma (NB) evaluated at diagnosis by anti-GD2 immunocytochemistry. Nineteen of these (13.1%) were found to be BM GD2-positive, with the number of positive cells ranging between 1 and 155 out of 1 × 106 total cells analysed. Seven/19 (38.8%) GD2-positive vs 12/126 (9.5%) GD2-negative patients relapsed. The 5-year event-free survival (EFS) and overall survival of the GD2-positive patients was significantly worse than that of the GD2-negative ones (62.2 vs 89.9%, P<0.001; and 74.9 vs 95.9%, P=0.005, respectively). GD2 positivity was not associated to other known risk factors, and in particular to Myc-N amplification and 1p deletion. Among Myc-N-negative patients, the EFS of those negative for both GD2 and 1p deletion was significantly better than in children positive for either one of these two markers (EFS=96.9 vs 66.0%, P<0.001). In conclusion, GD2 positivity may represent a prognostic marker for patients with non-metastatic NB without Myc-N amplification, and its combination with genetic alterations might help identifying patients that require a more careful follow-up.

    The 5-year survival rate is a good prognostic indicator for patients with Gastric cancer that is usually estimated based on Kaplan-Meier. In situations where censored observations are too many, this method produces biased estimations. This study aimed to compare estimations of Kaplan-Meier and Weighted Kaplan-Meier as an alternative method to deal with the problem of heavy-censoring. Data from 330 patients with Gastric cancer who had undergone surgery at Iran Cancer Institute from 1995- 1999 were analyzed. The Survival Time of these patients was determined after surgery, and the 5-year survival rate for these patients was evaluated based on Kaplan-Meier and Weighted Kaplan-Meier methods. A total of 239 (72.4%) patients passed away by the end of the study and 91(27.6%) patients were censored. The mean and median of survival time for these patients were 24.86±23.73 and 16.33 months, respectively. The one-year, two-year, three-year, four-year, and five-year survival rates of these patients with standard error estimation based on Kaplan-Meier were 0.66 (0.0264), 0.42 (0.0284), 0.31 (0.0274), 0.26 (0.0264) and 0.21 (0.0256) months, respectively. The estimations of Weighted Kaplan-Meier for these patients were 0.62 (0.0251), 0.35 (0.0237), 0.24 (0.0211), 0.17 (0.0172), and 0.10 (0.0125) months, consecutively. In cases where censoring assumption is not made, and the study has many censored observations, estimations obtained from the Kaplan-Meier are biased and are estimated higher than its real amount. But Weighted Kaplan-Meier decreases bias of survival probabilities by providing appropriate weights and presents more accurate understanding.

    Assessing the prognosis of patients with hepatocellular carcinoma (HCC) by the number and size of tumors is sometimes difficult. The main purpose of the study was to evaluate the prognostic value of total tumor volume (TTV), which combines the two factors, in patients with HCC who underwent liver resection. We retrospectively reviewed 521 HCC patients from January 2001 to December 2008 in our center. Patients were categorized using the tertiles of TTV. The prognostic value of TTV was assessed. With a median follow-up of 116 months, the 1-, 3-, and 5-year overall survival (OS) rates of the patients were 93.1 , 69.9, and 46.3 %, respectively. OS was significantly differed by TTV tertile groups, and higher TTV was associated with shorter OS (P < 0.001). Multivariate analysis revealed that TTV was an independent prognostic factor for OS. Larger TTV was significantly associated with higher alpha-fetoprotein level, presence of macrovascular invasion, multiple tumor lesions, larger tumor size, and advanced tumor stages (all P < 0.05). Within the first and second tertiles of TTV (TTV ≤ 73.5 cm(3)), no significant differences in OS were detected in patients within and beyond Milan criteria (P = 0.183). TTV-based Cancer of the Liver Italian Program (CLIP) score gained the lowest Akaike information criterion value, the highest χ (2) value of likelihood ratio test, and the highest C-index among the tested staging systems. Our results suggested that TTV is a good indicator of tumor burden in patients with HCC. Further studies are warranted to validate the prognostic value of TTV.

    Purpose: To retrospectively compare survival in recurrent uveal melanoma, between patients treated by enucleation or by a second course of fractionated proton beam therapy (PBT). Methods and Materials: Tumor recurrence was documented in 73 patients treated with PBT for uveal melanoma. Of the patients, 31 received a second course of PBT and 42 underwent enucleation. The mean patient age was 56 and 61 years for those undergoing enucleation and those undergoing reirradiation, respectively. Both primary and recurrent tumors were larger in patients undergoing enucleation. Tumor location and the presence or absence of ciliary body involvement did not differ significantly between the groups. The median follow-up after enucleation and after re-treatment was 79 and 59 months, respectively. Cumulative rates of outcomes and differences in rates between the reirradiated and enucleation groups were calculated by the Cox proportional hazards model and the log-rank test, respectively. Results: The median survival duration in the enucleated and reirradiated groups was 42 and 90 months, respectively. The median time free of metastases was 38 months in enucleated patients and 97 months in reirradiated patients. At 5 years after enucleation and after reirradiation, the probability of overall survival was 36% and 63%, respectively (p = 0.040, log-rank test); the probability of freedom from metastases was 31% and 66%, respectively (p = 0.028, log-rank test). These differences persisted after adjustment for recurrent tumor largest diameter and volume at the time of reirradiation or enucleation. Conclusions: This retrospective analysis suggests that survival in reirradiated patients is not compromised by administration of a second course of PBT for recurrent uveal melanoma.

    Circulating adiponectin is inversely related to the risk of colorectal cancer. However, its influence on colorectal cancer survival is unclear. We conducted a prospective study to evaluate the association between prediagnostic plasma levels of adiponectin and mortality in patients with colorectal cancer. We identified 621 incident colorectal cancer cases who provided blood specimens prior to diagnosis within the Nurses' Health Study (NHS) and Health Professionals Follow-up Study (HPFS). Cox proportional hazards models were used to calculate HRs and 95% confidence intervals (CI). After a median follow-up of 9 years, there were 269 (43%) total deaths, of which 181 (67%) were due to colorectal cancer. Compared with participants in the lowest quartile of adiponectin, those in the highest quartile had multivariate HRs of 1.89 (95% CI, 1.21-2.97; P(trend) = 0.01) for colorectal cancer-specific mortality and 1.66 (95% CI, 1.15-2.39; P(trend) = 0.009) for overall mortality. The apparent increased risk in colorectal cancer-specific mortality was more pronounced in patients with metastatic disease (HR, 3.02: 95% CI, 1.50-6.08). Among patients with colorectal cancer, prediagnostic plasma adiponectin is associated with an increased risk of colorectal cancer-specific and overall mortality and is more apparent in patients with metastatic disease. Adiponectin may be a marker for cancers which develop through specific pathways that may be associated with worsened prognosis. Further studies are needed to validate these findings.

    Circulating adiponectin is inversely related to the risk of colorectal cancer (CRC). However, its influence on CRC survival is unclear. We conducted a prospective study to evaluate the association between prediagnostic plasma levels of adiponectin and mortality in patients with CRC. We identified 621 incident CRC cases who provided blood specimens prior to diagnosis within the Nurses’ Health Study (NHS) and Health Professionals Follow-up Study (HPFS). Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). After a median follow-up of 9 years, there were 269 (43%) total deaths, of which 181 (67%) were due to CRC. Compared with participants in the lowest quartile of adiponectin, those in the highest quartile had multivariate HRs of 1.89 (95% CI, 1.21–2.97; Ptrend = 0.01) for CRC-specific mortality and 1.66 (95% CI, 1.15–2.39; Ptrend = 0.009) for overall mortality. The apparent increased risk in CRC-specific mortality was more pronounced in patients with metastatic disease (HR 3.02, 95% CI, 1.50–6.08).

    From 1967-1977, 560 patients with carcinoma of the lung were seen. Of these, 73 patients underwent lobectomy/pneumonectomy with/without postoperative radiation; 27 are alive today (Group A). Two hundred and seventy patients had distant metastasis when first seen, or it developed during treatment and so they were excluded from the study (Group B). One hundred ninety-seven patients were inoperable or unresectable intrathoraic unilateral (Group C) and treated with one of the following regimens: (1) High dose split course radiotherapy (RT) 3000 rad in 2 weeks followed by 2 weeks rest, then 3000 rad in 2 weeks (2150 ret). (2) Radiotherapy as in regimen1 followed by combination chemotherapy. (3) Continuous RT 6000 rad in 6 weeks. (4) Radiotherapy as in regimen3 followed by combination chemotherapy. (5) Combination chemotherapy alone. RT was administered by /sup 60/Cobalt unit. The survival percentages are discussed later. Chemotherapeutic agents consisted of 2 different drug regimens: vincristine + cyclophosphamide + adriamycin or cyclophosphamide + methotrexate + vincristine CCNU. The 5 month to 5 year survivals in Group C patients treated with two forms of RT techniques were comparable with RT + chemotherapy. Patients receiving chemotherapy alone had a shorter survival rate than those treated with RT alone. In July 1976 a new protocol was started for Stage II squamous cell carcinoma of the lung in which 22 patients received 5000 rad in 5 weeks and were randomized for immunotherapy to receive (a) Methanol Extract Residue (MER) every 4 weeks. (b) VAC (Vincristine) 1.4mg/m/sup 2/IV + adriamycin 50 mg/m/sup 2/IV + cyclophosphamide 500 mg/m/sup 2/IV every 4 weeks or (c) MER + VAC every 4 months. Median survivals for the different regimens were not statistically significant.

    Prognosis in colorectal cancer patients is quite variable, even after adjustment for clinical parameters such as disease stage and microsatellite instability status. It is possible that the psychological distress experienced by patients, including anxiety and depression, may be correlated with poor prognosis. In the present study, we hypothesize that genetic variations within three genes biologically linked to the stress response, namely serotonin transporter (SLC6A4), brain-derived neurotrophic factor (BDNF), and arginine vasopressin receptor (AVPR1B) genes are associated with prognosis in colorectal cancer patients. We used a population-based cohort of 280 patients who were followed for up to 12.5 years after diagnosis. Our multivariate analysis showed that a tagSNP in the SLC6A4 gene (rs12150214) was a predictor of shorter overall survival (HR: 1.572, 95%CI: 1.142–2.164, p = 0.005) independent of stage, age, grade and MSI status. Additionally, a multivariate analysis using the combined genotypes of three polymorphisms in this gene demonstrated that the presence of any of the minor alleles at these polymorphic loci was an independent predictor of both shorter overall survival (HR: 1.631, 95%CI: 1.190–2.236, p = 0.002) and shorter disease specific survival (HR: 1.691, 95%CI: 1.138–2.512, p = 0.009). The 5-HTT protein coded by the SLC6A4 gene has also been implicated in inflammation. While our results remain to be replicated in other patient cohorts, we suggest that the genetic variations in the SLC6A4 gene contribute to poor survival in colorectal cancer patients. PMID:22911682

    Background An association between volume and outcomes has been observed for esophagectomy, though little is known about why or how patients choose low- or high-volume centers. The purpose of this study was to evaluate how travel burden and hospital volume influence treatment and outcomes of patients with locally advanced esophageal cancer. Methods Predictors of receiving esophagectomy for patients with T1-3N1M0 mid or distal esophageal cancer in the National Cancer Data Base from 2006 to 2011 were identified using multivariable logistic regression. Survival was compared using propensity score-matched groups: patients in the bottom quartile of travel distance who underwent treatment at low-volume facilities (Local) and patients in the top quartile of travel distance who underwent treatment at high-volume facilities (Travel). Results Of 4979 patients who met inclusion criteria, we identified 867 Local patients who traveled 2.7 [interquartile range (IQR): 1.6–4 miles] miles to centers that treated 2.6 (IQR: 1.9–3.3) esophageal cancers per year, and 317 Travel patients who traveled 107.1 (IQR: 65–247) miles to centers treating 31.9 (IQR: 30.9–38.5) cases. Travel patients were more likely to undergo esophagectomy (67.8% vs 42.9%, P < 0.001) and had significantly better 5-year survival (39.8% vs 20.6%, P < 0.001) than Local patients. Conclusions Patients who travel longer distances to high-volume centers have significantly different treatment and better outcomes than patients who stay close to home at low-volume centers. Strategies that support patient travel for treatment at high-volume centers may improve esophageal cancer outcomes. PMID:28266965

    Purpose: To report the outcome of patients with synchronous, solitary brain metastasis from non-small-cell lung cancer (NSCLC) treated with gamma knife stereotactic radiosurgery (GKSRS). Patients and Methods: Forty-two patients diagnosed with synchronous, solitary brain metastasis from NSCLC were treated with GKSRS between 1993 and 2006. The median Karnofsky performance status (KPS) was 90. Patients had thoracic Stage I-III disease (American Joint Committee on Cancer 2002 guidelines). Definitive thoracic therapy was delivered to 26/42 (62%) patients; 9 patients underwent chemotherapy and radiation, 12 patients had surgical resection, and 5 patients underwent preoperative chemoradiation and surgical resection. Results: The median overall survival (OS) was 18 months. The 1-, 2-, and 5-year actuarial OS rates were 71.3%, 34.1%, and 21%, respectively. For patients who underwent definitive thoracic therapy, the median OS was 26.4 months compared with 13.1 months for those who had nondefinitive therapy, and the 5-year actuarial OS was 34.6% vs. 0% (p < 0.0001). Median OS was significantly longer for patients with a KPS {>=}90 vs. KPS < 90 (27.8 months vs. 13.1 months, p < 0.0001). The prognostic factors significant on multivariate analysis were definitive thoracic therapy (p = 0.020) and KPS (p = 0.001). Conclusions: This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy.

    Purpose/Objective(s): To determine the impact of adjuvant radiation treatment (RT) on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) in patients with high-risk 2009 International Federation of Gynecology and Obstetrics stage I-II endometrial carcinoma. Methods and Materials: We identified 382 patients with high-risk EC who underwent hysterectomy. RFS, DSS, and OS were calculated from the date of hysterectomy by use of the Kaplan-Meier method. Cox regression modeling was used to explore the risks associated with various factors on survival endpoints. Results: The median follow-up time for the study cohort was 5.4 years. The median age was 71 years. All patients underwent hysterectomy and salpingo-oophorectomy, 93% had peritoneal cytology, and 85% underwent lymphadenectomy. Patients with endometrioid histology constituted 72% of the study cohort, serous in 16%, clear cell in 7%, and mixed histology in 4%. Twenty-three percent of patients had stage II disease. Adjuvant management included RT alone in 220 patients (57%), chemotherapy alone in 25 patients (7%), and chemoradiation therapy in 27 patients (7%); 110 patients (29%) were treated with close surveillance. The 5-year RFS, DSS, and OS were 76%, 88%, and 73%, respectively. On multivariate analysis, adjuvant RT was a significant predictor of RFS (P<.001) DSS (P<.001), and OS (P=.017). Lymphovascular space involvement was a significant predictor of RFS and DSS (P<.001). High tumor grade was a significant predictor for RFS (P=.038) and DSS (P=.025). Involvement of the lower uterine segment was also a predictor of RFS (P=.049). Age at diagnosis and lymphovascular space involvement were significant predictors of OS: P<.001 and P=.002, respectively. Conclusion: In the treatment of patients with high-risk features, our study suggests that adjuvant RT significantly improves recurrence-free, disease-specific, and overall survival in patients with early-stage endometrial carcinoma

Treatment results were reviewed according to: (1) size of primary tumor; (2) base of skull invasion; (3) cranial nerve involvement; (4) cervical node metastases; and (5) distant spread. An appropriate staging system was developed that reflected these prognostic factors. The evidence presented indicates that in this series of patients, base of skull involvement was less ominous than cranial nerve involvement. Unilteral lymph node involvement carried a better prognosis than bilateral neck nodes, this was the poorest sign of all since it predicted distant metastases. The average 5-year survival rate for 1605 patients in all stages, was 529/1605(32.1%); the 10-year survival rate for 833 patients in all stages was 20.2%.

    AIM: To identify the clinical and prognostic features of patients with hepatocellular carcinoma (HCC) aged 80 years or more. METHODS: A total of 1310 patients with HCC were included in this study. Ninety-one patients aged 80 years or more at the time of diagnosis of HCC were defined as the extremely elderly group. Two hundred and thirty-four patients aged ≥ 50 years but less than 60 years were regarded as the non-elderly group. RESULTS: The sex ratio (male to female) was significantly lower in the extremely elderly group (0.90:1) than in the non-elderly group (3.9:1, P < 0.001). The positive rate for HBsAg was significantly lower in the extremely elderly group and the proportion of patients negative for HBsAg and HCVAb obviously increased in the extremely elderly group (P < 0.001). There were no significant differences in the following parameters: diameter and number of tumors, Child-Pugh grading, tumor staging, presence of portal thrombosis or ascites, and positive rate for HCVAb. Extremely elderly patients did not often receive surgical treatment (P < 0.001) and they were more likely to receive conservative treatment (P < 0.01). There were no significant differences in survival curves based on the Kaplan-Meier methods in comparison with the overall patients between the two groups. However, the survival curves were significantly worse in the extremely elderly patients with stage I/II, stage I/II and Child-Pugh grade A cirrhosis in comparison with the non-elderly group. The causes of death did not differ among the patients, and most cases died of liver-related diseases even in the extremely elderly patients. CONCLUSION: In the patients with good liver functions and good performance status, aggressive treatment for HCC might improve the survival rate, even in extremely elderly patients. PMID:16440416

    Allo-SCT is potentially curative for patients with AML. Patients transplanted in CR2 tend to experience inferior survival compared with those in CR1. We retrospectively investigated the impact of pretransplant variables on the outcome of patients transplanted with AML in CR2. Ninety-four patients with AML in CR2 received a transplant between 1999 and 2011 with myeloablative (MA, n=65) or reduced-intensity conditioning regimens (RIC, n=29). Variables investigated included cytogenetic risk at diagnosis (SWOG), hematopoietic cell transplantation-specific comorbidity index (HCT-CI), CMV status, duration of CR1 and age. Median age of all patients was 47 years (range 18-70). Multivariable analysis for OS identified three prognostically significant categories: a favorable risk group included patients with duration of CR1 ≥6 months, age <55 years and HCT-CI score 0-3, an intermediate risk group with duration of CR1 ≥6 months, age <55 years and HCT-CI score 4-5 and a high-risk group with duration of CR1 <6 months or age ≥55 years (P=0.0001) with 5-year survivals of 53%, 31% and 6%, respectively. Acute and chronic GVHD did not influence this risk stratification. The stated risk factors discriminate patients with different OS and may assist in decision making for allo-SCT.

    This study assesses the caries prevalence, retention and cost-effectiveness of a pit and fissure sealant in a children population with 622 cases, 5 years after a single application of an auto-polymerized sealant to permanent molars. The status of the sealant and the presence of caries or restaurations on the sealed teeth was assessed. In a self-controlled group of children, the prevalence of disease (caries and restaurations) was also assessed in non-sealed teeth, for comparison. The sealant application was compared with Class I-restauration with amalgam for cost-effectiveness analysis.

    Abstract Selective estrogen receptor modulator (SERM)-associated nonalcoholic fatty liver disease (NAFLD) might be related to treatment efficacy in patients with breast cancer because of circulating estrogen antagonism. The aim of the study was to investigate the relationship between NAFLD and survival outcomes in patients with breast cancer who were treated with tamoxifen or toremifene. This single-center, retrospective, cohort study included 785 eligible patients who received tamoxifen or toremifene, after curative resection for breast cancer, at the Sun Yat-sen University Cancer Center between January 2005 and December 2009. Data were extracted from patient medical records. All patients underwent abdominal ultrasonography, at least once, at baseline and at the annual follow-up. Patients who were diagnosed with NAFLD on ultrasonography were classified into the NAFLD or the non-NAFLD arm at the 3-year follow-up visit. Univariate and multivariate Cox regression analyses were conducted to evaluate any associations between NAFLD and disease-free survival (DFS) or overall survival (OS). One hundred fifty-eight patients were diagnosed with NAFLD. Patients who developed NAFLD had better DFS and OS compared with those who did not. Univariate analyses revealed that the 5-year DFS rates were 91.56% and 85.01% for the NAFLD and non-NAFLD arms, respectively (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.37–0.96; log-rank P = 0.032). The 5-year OS rates were 96.64% and 93.31% for the NAFLD and non-NAFLD arms, respectively (HR, 0.39; 95% CI, 0.16–0.99; log-rank P = 0.039). Multivariate analysis revealed that NAFLD was an independent prognostic factor for DFS, improving the DFS rate by 41% compared with that in the non-NAFLD arm (HR, 0.59; 95% CI, 0.36–0.96; P = 0.033). SERM-associated NAFLD was independently associated with improved DFS and might be useful for predicting treatment responses in breast cancer patients treated with SERMs. PMID

    Androgens, estrogens, progesterone and related signals are reported to be involved in the pathology of gastric cancer. However, varied conclusions exist based on serum hormone levels, receptor expressions, and in vitro or in vivo studies. This report used a web-based gene survival analyzer to evaluate biochemical processes, including cholesterol importing via lipoprotein/receptors (L/R route), steroidogenic enzymes, and steroid receptors, in gastric cancer patients prognosis. The sex hormone receptors (androgen receptor, progesterone receptor, and estrogen receptor ESR1 or ESR2), L/R route (low/high-density lipoprotein receptors, LDLR/LRP6/SR-B1 and lipoprotein lipase, LPL) and steroidogenic enzymes (CYP11A1, HSD3B1, CYP17, HSD17B1, HSD3B1, CYP19A1 and SRD5A1) were associated with 5-year survival of gastric cancer patients. The AR, PR, ESR1 and ESR2 are progression promoters, as are the L/R route LDLR, LRP6, SR-B1 and LPL. It was found that CYP11A1, HSD3B1, CYP17, HSD17B1 and CYP19A1 promote progression, but dihydrotestosterone (DHT) converting enzyme SRD5A1 suppresses progression. Analyzing steroidogenic lipidome with a hazard ratio score algorithm found that CYP19A1 is the progression confounder in surgery, HER2 positive or negative patients. Finally, in the other patient cohort from TCGA, CYP19A1 was expressed higher in the tumor compared to that in normal counterparts, and also promoted progression. Lastly, exemestrane (type II aromatase inhibitor) dramatically suppress GCa cell growth in pharmacological tolerable doses in vitro. This work depicts a route-specific outside-in delivery of cholesterol to promote disease progression, implicating a host-to-tumor macroenvironmental regulation. The result indicating lipoprotein-mediated cholesterol entry and steroidogenesis are GCa progression biosignatures. And the exemestrane clinical trial in GCa patients of unmet medical needs is suggested. PMID:27893427

    Background Low serum parathyroid hormone (PTH) has been implicated as a primary biochemical marker of adynamic bone disease in individuals with chronic kidney disease (CKD) who undergo maintenance hemodialysis (MHD) treatment. We hypothesized that the malnutrition-inflammation complex is associated with low PTH levels in these patients and confounds the PTH-survival association. Methods We examined 748 stable MHD outpatients in Southern California and followed them for up to 5 years (10/2001-12/2006). Results In 748 MHD patients, serum PTH <150 pg/ml was more prevalent among non-Blacks and diabetics. There was no association between serum PTH and coronary artery calcification score, bone mineral density or dietary protein or calorie intake. Low serum PTH was associated with markers of protein-energy wasting and inflammation, and this association confounded the relationship between serum PTH and alkaline phosphatase. Although 5-year crude mortality rates were similar across PTH increments, after adjustment for the case-mix and surrogates of malnutrition and inflammation, a moderately low serum PTH in 100 to 150 pg/ml range was associated with the greatest survival compared to other serum PTH levels, i.e., a death hazard ratio of 0.52 (95% confidence interval: 0.29-0.92, p<0.001) compared to PTH of 300 to 600 pg/ml (reference). Conclusions Low serum PTH may be another facet of the malnutrition-inflammation complex in CKD, and after controlling for this confounder, a moderately low PTH in 100 to 150 pg/ml range appears associated with the greatest survival. Limitations of observational studies should be considered. PMID:20199875

    Purpose: Survival in oral cavity squamous cell carcinoma (OSCC) depends heavily on locoregional control. In this prospective study, we sought to investigate whether preoperative maximum standardized uptake value of the neck lymph nodes (SUVnodal-max) may predict prognosis in OSCC patients. Methods and Materials: A total of 120 OSCC patients with pathologically positive lymph nodes were investigated. All subjects underwent a [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) scan within 2 weeks before radical surgery and neck dissection. All patients were followed up for at least 24 months after surgery or until death. Postoperative adjuvant therapy was performed in the presence of pathologic risk factors. Optimal cutoff values of SUVnodal-max were chosen based on 5-year disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS). Independent prognosticators were identified by Cox regression analysis. Results: The median follow-up for surviving patients was 41 months. The optimal cutoff value for SUVnodal-max was 5.7. Multivariate analyses identified the following independent predictors of poor outcome: SUVnodal-max {>=}5.7 for the 5-year neck cancer control rate, distant metastatic rate, DFS, DSS, and extracapsular spread (ECS) for the 5-year DSS and OS. Among ECS patients, the presence of a SUVnodal-max {>=}5.7 identified patients with the worst prognosis. Conclusion: A SUVnodal-max of 5.7, either alone or in combination with ECS, is an independent prognosticator for 5-year neck cancer control and survival rates in OSCC patients with pathologically positive lymph nodes.

    Smoking is associated with prostate cancer mortality. The Scandinavian smokeless tobacco product snus is a source of nicotine but not the combustion products of smoke and has not been studied with respect to prostate cancer survival. The study is nested among 9,582 men with incident prostate cancer within a prospective cohort of 336,381 Swedish construction workers. Information on tobacco use was collected at study entry between 1971 and 1992, and categorized into (i) never users of any tobacco, (ii) exclusive snus: ever users of snus only, (iii) exclusive smokers: ever smokers (cigarette, cigar and/or pipe) only and (iv) ever users of both snus and smoking. Hazard ratios for prostate cancer-specific and total mortality for smoking and snus use based on Cox proportional hazards models adjusted for age, calendar period at diagnosis and body mass index at baseline. During 36 years of follow-up, 4,758 patients died-2,489 due to prostate cancer. Compared to never users of tobacco, exclusive smokers were at increased risk of prostate cancer mortality (HR 1.15, 95% CI: 1.05-1.27) and total mortality (HR 1.17, 95% CI: 1.09-1.26). Exclusive snus users also had increased risks for prostate cancer mortality (HR 1.24, 95% CI: 1.03-1.49) and total mortality (HR 1.19, 95% CI: 1.04-1.37). Among men diagnosed with nonmetastatic disease, the HR for prostate cancer death among exclusive snus users was 3.17 (95% CI: 1.66-6.06). The study is limited by a single assessment of tobacco use prior to diagnosis. Snus use was associated with increased risks of prostate cancer and total mortality among prostate cancer patients. This suggests that tobacco-related components such as nicotine or tobacco-specific carcinogens may promote cancer progression independent of tobacco's combustion products.

    We have developed statistical models for predicting survival in patients with stage IIB–III thoracic esophageal squamous cell carcinoma (ESCC) and assessing the efficacy of adjuvant treatment. From a retrospective review of 3,636 patients, we created a database of 1,004 patients with stage IIB–III thoracic ESCC who underwent esophagectomy with or without postoperative radiation. Using a multivariate Cox regression model, we assessed the prognostic impact of clinical and histological factors on overall survival (OS). Logistic analysis was performed to identify factors to include in a recursive partitioning analysis (RPA) to predict 5-year OS. The nomogram was evaluated internally based on the concordance index (C-index) and a calibration plot. The median survival time in the training dataset was 30.9 months, and the 5-year survival rate was 33.9%. T stage, differentiated grade, adjuvant treatment, tumor location, lymph node metastatic ratio (LNMR), and the presence of vascular carcinomatous thrombi were statistically significant predictors of 5-year OS. The C-index of the nomogram was 0.70 (95% CI 0.67–0.73). RPA resulted in a three-class stratification: class 1, LNMR ≤ 0.15 with adjuvant treatment; class 2, LNMR ≤ 0.15 without adjuvant treatment and LNMR > 0.15 with adjuvant treatment; and class 3, LNMR > 0.15 without adjuvant treatment. The three classes were statistically significant for OS (P < 0.001). Thus, the nomogram and RPA models predicted the prognosis of stage IIB–III ESCC patients and could be used in decision-making and clinical trials. PMID:27487146

    Purpose: To report the 5-year results of a technique of prone breast radiation therapy delivered by a regimen of accelerated intensity modulated radiation therapy with a concurrent boost to the tumor bed. Methods and Materials: Between 2003 and 2006, 404 patients with stage I-II breast cancer were prospectively enrolled into 2 consecutive protocols, institutional trials 03-30 and 05-181, that used the same regimen of 40.5 Gy/15 fractions delivered to the index breast over 3 weeks, with a concomitant daily boost to the tumor bed of 0.5 Gy (total dose 48 Gy). All patients were treated after segmental mastectomy and had negative margins and nodal assessment. Patients were set up prone: only if lung or heart volumes were in the field was a supine setup attempted and chosen if found to better spare these organs. Results: Ninety-two percent of patients were treated prone, 8% supine. Seventy-two percent had stage I, 28% stage II invasive breast cancer. In-field lung volume ranged from 0 to 228.27 cm{sup 3}, mean 19.65 cm{sup 3}. In-field heart volume for left breast cancer patients ranged from 0 to 21.24 cm{sup 3}, mean 1.59 cm{sup 3}. There was no heart in the field for right breast cancer patients. At a median follow-up of 5 years, the 5-year cumulative incidence of isolated ipsilateral breast tumor recurrence was 0.82% (95% confidence interval [CI] 0.65%-1.04%). The 5-year cumulative incidence of regional recurrence was 0.53% (95% CI 0.41%-0.69%), and the 5-year overall cumulative death rate was 1.28% (95% CI 0.48%-3.38%). Eighty-two percent (95% CI 77%-85%) of patients judged their final cosmetic result as excellent/good. Conclusions: Prone accelerated intensity modulated radiation therapy with a concomitant boost results in excellent local control and optimal sparing of heart and lung, with good cosmesis.

    Several parameters of preoperative complete blood count (CBC) and inflammation-associated blood cell markers derived from them have been reported to correlate with prognosis in patients with epithelial ovarian cancer (EOC), but their prognostic importance and optimal cutoffs are still needed be elucidated. Clinic/pathological parameters, 5-year follow-up data and preoperative CBC parameters were obtained retrospectively in 654 EOC patients underwent primary surgery at Mayo Clinic. Cutoffs for neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) were optimized by receiver operating characteristic (ROC) curve. Prognostic significance for overall survival (OS) and recurrence free survival (RFS) were determined by Cox proportional hazards models and Kaplan-Meier method. Associations of RDW and NLR with clinic/pathological parameters were analyzed using non-parametric tests. RDW with cutoff 14.5 and NLR with cutoff 5.25 had independent prognostic significance for OS, while combined RDW and NLR scores stratified patients into low (RDW-low and NLR-low), intermediate (RDW-high or NLR-high) and high risk (RDW-high and NLR-high) groups, especially in patients with high-grade serous ovarian cancer (HGSOC). Moreover, high NLR was associated with poor RFS as well. Elevated RDW was strongly associated with age, whereas high NLR was strongly associated with stage, preoperative CA125 level and ascites at surgery. PMID:28223716

    Background Human papillomavirus (HPV) is an oncogenic virus causing oropharyngeal cancers and resulting in a favorable outcome after the treatment. The role of HPV in oral cavity squamous cell carcinoma (OSCC) remains ambiguous. Objective This study aimed to examine the effect of HPV infection on disease control among patients with OSCC following radical surgery with radiation-based adjuvant therapy. Patients and Method We prospectively followed 173 patients with advanced OSCC (96% were stage III/IV) who had undergone radical surgery and adjuvant therapy between 2004 and 2006. They were followed between surgery and death or up to 60 months. Surgical specimens were examined using a PCR-based HPV blot test. The primary endpoints were the risk of relapse and the time to relapse; the secondary endpoints were disease-free survival, disease-specific survival, and overall survival. Results The prevalence of HPV-positive OSCC was 22%; HPV-16 (9%) and HPV-18 (7%) were the genotypes most commonly encountered. Solitary HPV-16 infection was a poor predictor of 5-year distant metastases (hazard ratio, 3.4; 95% confidence interval, 1.4–8.0; P = 0.005), disease-free survival (P = 0.037), disease-specific survival (P = 0.006), and overall survival (P = 0.010), whereas HPV-18 infection had no impact on 5-year outcomes. The rate of 5-year distant metastases was significantly higher in the HPV-16 or level IV/V metastasis group compared with both the extracapsular spread or tumor depth ≥11-mm group and patients without risk factors (P<0.001). Conclusions HPV infections in advanced OSCC patients are not uncommon and clinically relevant. Compared with HPV-16-negative advanced OSCC patients, those with a single HPV-16 infection are at higher risk of distant metastases and poor survival despite undergoing radiation-based adjuvant therapy and require a more aggressive adjuvant treatment and a more thorough follow-up.

    Purpose This study examined diet-related problems and needs associated with nutritional care according to survival stage in Korean female cancer survivors. Methods 186 outpatients (breast or gynecologic cancer survivors) recruited. Subjects were classified as (1) extended stage (ES, 2–5 years from diagnosis) and (2) long-term stage (LS, ≥5 years from diagnosis). Eating habits, changes in health related factors, nutritional needs, and quality of life were investigated. Results 43% of ES survivors had diet-related problems (p = .031); ES group reported dyspepsia and LS group reported anorexia/nausea as the major problem. Half of ES survivors had taste change, decreasing amount of intake, and reduced quality of life (p < .05). The LS group had a greater preference for sweet tastes than the ES group. According to their diagnosis, ES survivors with breast cancer gained weight (27.1%), whereas ES survivors with gynecologic cancer lost their body weight (34.5%) significantly. LS breast cancer patients showed great food preference for vegetables, whereas those with gynecologic cancer showed an increased preference for fish, meat and grain. Approximately 90% of survivors demanded nutritional care regarding restricted foods, preventing recurrence, particularly in ES survivors (p < .01). Moreover, main factors for nutritional care needs were body weight control for breast cancer and food environment for gynecologic cancer. Conclusion Survivors have different aspects of diet-related problems by survival stage as dyspepsia in ES and anorexia in LS. ES stage had changes in dietary patterns and their food consumption have decreased. Most of survivors have demanded nutritional care regardless of survival stage. These features of each stage should be considered to improve their health. PMID:27695041

    Marital status has been reported as an independent prognostic factor for survival in various cancers, but it has been rarely studied in hepatocellular carcinoma (HCC) treated by surgical resection. We retrospectively investigated Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 13,408 cases of HCC with surgical treatment between 1998 and 2013. The patients were categorized according to marital status, as “married,” “never married,” “widowed,” or “divorced/separated.” The 5-year HCC cause-specific survival (HCSS) data were obtained, and Kaplan–Meier methods and multivariate Cox regression models were used to ascertain whether marital status is also an independent prognostic factor for survival in HCC. Patients in the widowed group had the higher proportion of women, a greater proportion of older (>60 years) patients, more frequency in latest year of diagnosis (2008-2013), a greater number of tumors at TNM stage I/II, and more prevalence at localized SEER Stage, all of which were statistically significant within-group comparisons (P < 0.001). Marital status was demonstrated to be an independent prognostic factor by multivariate survival analysis (P < 0.001). Married patients had better 5-year HCSS than did unmarried patients (46.7% vs 37.8%) (P < 0.001); conversely, widowed patients had lowest HCSS compared with all other patients, overall, at each SEER stage, and for different tumor sizes. Marital status is an important prognostic factor for survival in patients with HCC treated with surgical resection. Widowed patients have the highest risk of death compared with other groups.

    Little information is available about survival of high-risk pediatric neuroblastoma patients in developing countries. We aimed to assess survival among high-risk pediatric neuroblastoma patients in La Plata, Argentina. Individuals eligible for our cohort were aged <20 yr when diagnosed with high-risk neuroblastoma and received cancer-directed therapy including stem cell transplantation at Hospital de Niños Sor Maria Ludovica between February 1999 and February 2015. We estimated overall survival probabilities using an extended Kaplan-Meier approach. Our study population comprised 39 high-risk neuroblastoma patients, of whom 39% were aged >4 yr at diagnosis, 54% were male, and 62% had adrenal neuroblastoma. We observed 18 deaths, and the median survival time of our study population was 1.7 yr. The five-yr overall survival probability was 24% (95% CL: 10%, 41%). In contrast, five-yr survival of high-risk neuroblastoma patients ranges between 23% and 76% in developed countries. Survival among high-risk neuroblastoma patients is generally poor regardless of geographic location, but our results illustrate dramatically worse survival for patients in a developing country. We speculate that the observed survival differences could be attenuated or eliminated with improvements in treatment and supportive care, but addressing these issues will require creative solutions because of resource limitations.

    Background Cardiac tumors are rare but manifested with various clinical presentations and often cause unexpected symptoms or sudden death. The objective is to review the clinical presentation, histopathological spectrum, mortality and follow-up data of patients with cardiac tumors following surgery treatment over a period of 5 years. Methods We retrospectively collected the medical records of all patients diagnosed of cardiac tumors in the period between January 2008 and December 2013 at the cardiac center of our university. Clinical histories, perioperative data, surgical findings, efficacy and follow-up data were reviewed in our study. Patients were divided into two groups according to site distribution of the tumors in the heart. Results A total of 131 patients underwent surgical treatment of cardiac tumors were enrolled in this study, with a mean age of 51.39±16.37. The result of analysis showed that 79.47% (n=104) of the primary intracardiac tumors were benign, while primary malignant neoplasms accounted for 16.03% (n=21) of all patients, with the remainder (n=6, 4.6%) metastatic tumors transferred from other organs. Among all patients there were 2 in-hospital deaths and the survival rate in all patients at 1-year, 3-year and 5-year follow up was 83.20%, 78.62% and 66.41% respectively. Both patients with tumors in the left and right heart had similar basic characteristics except sex gender (P=0.002), BSA (P=0.045) and weight (P=0.033). Compared with patients with tumors in the right heart, patients with tumors in the left heart had significant higher CPB time (P<0.001), cross clamp time (P<0.001) and time of mechanical ventilation (P<0.001), and they also had longer ICU stay (P<0.001) but not total hospital stay (P=0.434). Conclusions Surgical resection represents an effective protocol in treating cardiac tumors. Data in our study of cardiac tumors on frequency and allocation were consistent with previous reports which may provide useful clinical evidence on

    Purpose To investigate the effects of lymph node metastasis, skip metastasis, and other factors related to lymph node status on survival in patients who underwent radical cystectomy (RC) and extended lymph node dissection (eLND). Materials and Methods RC and eLND were performed in 85 patients with a diagnosis of bladder cancer. Disease-free survival (DFS) and overall survival (OS) were determined by using a Cox proportional hazards model that included the number of excised lymph nodes, the presence of pathological lymph node metastasis, the anatomical level of positive nodes, the number of positive lymph nodes, lymph node density, and the presence of skip metastasis. Results The mean number of lymph nodes removed per patient was 29.4±9.3. Lymph node positivity was detected in 85 patients (34.1%). The mean follow-up duration was 44.9±27.4 months (2-93 months). Five-year estimated OS and DFS for the 85 patients were 62.6% and 57%, respectively. Three of 29 lymph node-positive patients (10.3%) had skip metastasis. Only lymph node positivity had a significant effect on 5-year OS and DFS (p<0.001). No difference in OS and DFS was found between the three patients with skip metastasis and other lymph node-positive patients. Other factors related to lymph node status had no significant effect on 5-year OS and DFS. Conclusions No factors related to lymph node status predict DFS and OS, except for lymph node positivity. OS and DFS were comparable between patients with skip metastasis and other lymph node-positive patients. PMID:25964836

    The aim of this study was to evaluate the success of one-stage implants placed at the time of alveolar bone augmentation using simultaneous guided bone regeneration technique with a collagen barrier membrane in patients suffering from insufficient bone width. Seventeen patients were treated with 20 one-stage OSTEOFIX (Oulu, Finland) implants using simultaneous guided bone regeneration technique. Dehiscence defects were filled by bovine bone mineral Bio-Oss and covered with collagen membrane. Clinical and radiographic parameters of the peri-implant conditions were assessed at the moment of prosthesis placement and at 1- and 5-year follow-ups. Diagnostic dehiscence defect measurements after implant placement showed that the mean vertical defect varied from 3.8 mm to 10.0 mm. At the moment of prosthesis placement and at 1- and 5-year follow-ups all implants were stable, painless and without biological complications. Clinical and radiographic parameters of the peri-implant conditions remained stable during follow-up. The cumulative implant survival rate was 100% after the 5-year observation period and the success rate for all pooled implants was 90%. The present study showed predictable treatment outcomes recorded after 5 years of function for one-stage OSTEOFIX (Oulu, Finland) oral implants placed simultaneously with guided bone regeneration using collagen membrane and deproteinized bovine bone mineral.

    Depressive symptoms and poor health perceptions are predictors of higher hospitalization and mortality rates (heart failure [HF]). However, the association between depressive symptoms and health perceptions as they affect event-free survival outcomes in patients with HF has not been studied. The purpose of this secondary analysis was to determine whether depressive symptoms mediate the relationship between health perceptions and event-free survival in patients with HF. A total of 458 HF patients (61.6 ± 12 years, 55% New York Heart Association Class III/IV) responded to one-item health perception question and completed the Patient Health Questionnaire-9. Event-free survival data were collected for up to 4 years. Multiple regression and Cox proportional hazards regression analysis showed that depressive symptoms mediated the relationship between health perceptions and event-free survival. Decreasing depressive symptoms is essential to improve event-free survival in patients with HF.

    Quantifying cancer patient survival from the perspective of cure is clinically relevant. However, most cure models estimate cure assuming no competing causes of death. We use a relative survival framework to demonstrate how flexible parametric cure models can be used in combination with competing-risks theory to incorporate noncancer deaths. Under a model that incorporates statistical cure, we present the probabilities that cancer patients (1) have died from their cancer, (2) have died from other causes, (3) will eventually die from their cancer, or (4) will eventually die from other causes, all as a function of time since diagnosis. We further demonstrate how conditional probabilities can be used to update the prognosis among survivors (eg, at 1 or 5 years after diagnosis) by summarizing the proportion of patients who will not die from their cancer. The proposed method is applied to Swedish population-based data for persons diagnosed with melanoma, colon cancer, or acute myeloid leukemia between 1973 and 2007.

    African American patients of colorectal cancer (CRC) were found to have a worse prognosis than Caucasians, but it has not been fully understood about the survival difference among Chinese and these two races above. In this study, we used the Surveillance, Epidemiology and End Results database to analyze the survival difference among these three race/ethnicities in the United States. Adenocarcinoma patients of colorectal cancer with a race/ethnicity of Caucasian, Chinese and African American were enrolled for study. Patients were excluded if they had more than one primary cancer but the CRC was not the first one, had unknown cause of death or unknown survival months. The 5-year cause specific survival (CSS) was our primary endpoint. Totally, there were 585,670 eligible patients for analysis. Chinese patients had the best and African American patients had the worst 5-year CSS (66.7% vs 55.9%), P < 0.001. The 5-year CSS for Caucasian patients was 62.9%. Race/ethnicity was an independent prognostic factor in the multivariate analysis, P < 0.001. The comparison of clinicopathologic factors among these three race/ethnicities showed that the insurance coverage rate, income, percentage that completing high school and percentage of urban residence was lowest in the African American patients. Chinese patients had the highest percentage of married, while African American patients ranked lowest. More African American patients were diagnosed as stage IV and had high percentage of signet ring cell and mucinous adenocarcinoma. It is likely that biological differences as well as socioeconomic status both contribute to the survival disparity among the different race/ethnicities.

    Objective The long-term survival of in-hospital cardiac arrest (IHCA) patients treated with targeted temperature management (TTM) is poorly described. The aim of this study was to compare the outcomes of consecutive IHCA with out-of-hospital cardiac arrest (OHCA) patients treated with TTM. Design, setting, and patients Retrospectively collected data on all consecutive adult patients treated with TTM at a university tertiary heart center between 2005 and 2011 were analyzed. Measurements Primary endpoints were survival to hospital discharge and long-term survival. Secondary endpoint was neurological outcome assessed using the Pittsburgh cerebral performance category (CPC). Results A total of 282 patients were included in this study; 233 (83%) OHCA and 49 (17%) IHCA. The IHCA group presented more often with asystole, received bystander cardiopulmonary resuscitation (CPR) in all cases, and had shorter time to return of spontaneous circulation (ROSC). Survival to hospital discharge was 54% for OHCA and 53% for IHCA (adjusted odds ratio 0.98 [95% confidence interval {CI}; 0.43–2.24]). Age ≤60 years, bystander CPR, time to ROSC ≤10 min, and shockable rhythm at presentation were associated with survival to hospital discharge. Good neurologic outcome among survivors was achieved by 86% of OHCA and 92% of IHCA (P=0.83). After a median follow-up time of >5 years, 83% of OHCA and 77% of IHCA were alive (adjusted hazard ratio [HR] 1.51 [95% CI; 0.59–3.91]). Age ≤60 years was the only factor associated with long-term survival (adjusted HR 2.73 [95% CI; 1.36–5.52]). Conclusion There was no difference in short- and long-term survival and no difference in neurologic outcome to hospital discharge between IHCA and OHCA patients treated with TTM despite higher frequency of asystole in IHCA.

    Objectives We studied survival and associated risk factors in an Italian nationwide cohort of HIV-infected individuals after an AIDS-defining cancer (ADC) or non-AIDS-defining cancer (NADC) diagnosis in the modern cART era. Methods Multi-center, retrospective, observational study of HIV patients included in the MASTER Italian Cohort with a cancer diagnosis from January 1998 to September 2012. Malignancies were divided into ADC or NADC on the basis of the Centre for Disease Control-1993 classification. Recurrence of cancer and metastases were excluded. Survivals were estimated according to the Kaplan-Meier method and compared according to the log-rank test. Statistically significant variables at univariate analysis were entered in a multivariate Cox regression model. Results Eight hundred and sixty-six cancer diagnoses were recorded among 13,388 subjects in the MASTER Database after 1998: 435 (51%) were ADCs and 431 (49%) were NADCs. Survival was more favorable after an ADC diagnosis than a NADC diagnosis (10-year survival: 62.7%±2.9% vs. 46%±4.2%; p = 0.017). Non-Hodgkin lymphoma had lower survival rates than patients with Kaposi sarcoma or cervical cancer (10-year survival: 48.2%±4.3% vs. 72.8%±4.0% vs. 78.5%±9.9%; p<0.001). Regarding NADCs, breast cancer showed better survival (10-year survival: 65.1%±14%) than lung cancer (1-year survival: 28%±8.7%), liver cancer (5-year survival: 31.9%±6.4%) or Hodgkin lymphoma (10-year survival: 24.8%±11.2%). Lower CD4+ count and intravenous drug use were significantly associated with decreased survival after ADCs or NADCs diagnosis. Exposure to cART was found to be associated with prolonged survival only in the case of ADCs. Conclusions cART has improved survival in patients with an ADC diagnosis, whereas the prognosis after a diagnosis of NADCs is poor. Low CD4+ counts and intravenous drug use are risk factors for survival following a diagnosis of ADCs and Hodgkin lymphoma in the NADC group. PMID:24760049

    Background Clinical trials test the efficacy of a treatment in a select patient population. We examined whether cancer clinical trial patients were similar to nontrial, “real-world” patients with respect to presenting characteristics and survival. Methods We reviewed the SWOG national clinical trials consortium database to identify candidate trials. Demographic factors, stage, and overall survival for patients in the standard arms were compared with nontrial control subjects selected from the Surveillance, Epidemiology, and End Results program. Multivariable survival analyses using Cox regression were conducted. The survival functions from aggregate data across all studies were compared separately by prognosis (≥50% vs <50% average 2-year survival). All statistical tests were two-sided. Results We analyzed 21 SWOG studies (11 good prognosis and 10 poor prognosis) comprising 5190 patients enrolled from 1987 to 2007. Trial patients were younger than nontrial patients (P < .001). In multivariable analysis, trial participation was not associated with improved overall survival for all 11 good-prognosis studies but was associated with better survival for nine of 10 poor-prognosis studies (P < .001). The impact of trial participation on overall survival endured for only 1 year. Conclusions Trial participation was associated with better survival in the first year after diagnosis, likely because of eligibility criteria that excluded higher comorbidity patients from trials. Similar survival patterns between trial and nontrial patients after the first year suggest that trial standard arm outcomes are generalizable over the long term and may improve confidence that trial treatment effects will translate to the real-world setting. Reducing eligibility criteria would improve access to clinical trials. PMID:24627276

    Although the life expectancy of patients with end-stage renal disease (ESRD) has improved in recent years, it is still far below that of the general population. In this retrospective study, we compared the survival of patients with ESRD receiving hemodialysis (HD) versus those on peritoneal dialysis (PD). The study was conducted on patients referred to the HD and PD centers of the Emam Khomini Hospital and the Aboozar Children's Hospital from January 2007 to May 2012 in Ahvaz, Iran. All ESRD patients on maintenance HD or PD for more than two months were included in the study. The survival was estimated by the Kaplan-Meier method and the differences between HD and PD patients were tested by the log-rank test. Overall, 239 patients, 148 patients on HD (61.92%) and 91 patients on continuous ambulatory PD (CAPD) (38.55%) with mean age of 54.1 ± 17 years were enrolled in the study. Regardless of the causes of ESRD and type of renal replacement therapy (RRT), one-, two- and three-year survival of patients was 65%, 51% and 35%, respectively. There was no significant difference between type of RRT in one- (P-value = 0.737), two- (P-value = 0.534) and three- (P-value = 0.867) year survival. There was also no significant difference between diabetic and non-diabetic patients under HD and CAPD in the one-, two- and three-year survival. Although the three-year survival of diabetic patients under CAPD was lower than that of non-diabetic patients (13% vs. 34%), it was not statistically significant (P-value = 0.50). According to the results of the current study, there is no survival advantage of PD during the first years of initiation of dialysis, and the one-, two- and three-year survival of HD and PD patients is also similar.

    2010-01-01

    Background The breast is a rare extranodal site of non-Hodgkin lymphoma, and primary breast lymphoma (PBL) has been arbitrarily defined as disease localized to one or both breasts with or without regional lymph nodes involvement. The aim of this study was to evaluate the clinical outcomes in patients with diffuse large B cell lymphoma (DLBCL) and breast involvement, and to find the criteria of PBL reflecting the outcome and prognosis. Methods We retrospectively analyzed data from 68 patients, newly diagnosed with DLBCL and breast involvement at 16 Korean institutions between January 1994 and June 2009. Results Median age at diagnosis was 48 years (range, 20-83 years). Forty-three (63.2%) patients were PBL according to previous arbitrary criteria, sixteen (23.5%) patients were high-intermediate to high risk of international prognostic index. The patients with one extranodal disease in the breast (OED) with or without nodal disease were 49 (72.1%), and those with multiple extranodal disease (MED) were 19 (27.9%). During median follow-up of 41.5 months (range, 2.4-186.0 months), estimated 5-year progression-free survival (PFS) was 53.7 ± 7.6%, and overall survival (OS) was 60.3 ± 7.2%. The 5-year PFS and OS was significantly higher for patients with the OED group than those with the MED group (5-year PFS, 64.9 ± 8.9% vs. 27.5 ± 11.4%, p = 0.001; 5-year OS, 74.3 ± 7.6% vs. 24.5 ± 13.0%, p < 0.001). In multivariate analysis, MED (hazard ratio [HR], 3.61; 95% confidence interval [CI], 1.07-12.2) and fewer than four cycles of systemic chemotherapy with or without local treatments (HR, 4.47; 95% CI, 1.54-12.96) were independent prognostic factors for worse OS. Twenty-five (36.8%) patients experienced progression, and the cumulative incidence of progression in multiple extranodal sites or other than breasts and central nervous system was significantly different between the OED group and the MED group (5-year cumulative incidence, 9.7 ± 5.4% vs. 49.0 ± 15.1%, p = 0

    Although Japanese cases of sporadic Creutzfeldt-Jakob disease (sCJD) generally involve longer survival periods compared to those from other countries, details regarding the factors influencing survival are unclear. To determine the influence of certain factors on survival, we retrospectively assessed 51 Japanese MM1-type sCJD patients with respect to background, clinical course, and disease management. No significant differences were found between men and women, tracheotomy and nontracheotomy patients, or patients treated in public and other types of hospitals. Although the survival period of tube-fed patients was significantly longer than that of patients who were not tube fed, survival of patients fed via a nasal tube did not differ significantly from that of gastrostomy-fed patients. The proportion of tube-fed patients was 68.6% (35/51). Disease duration was not significantly associated with age or year of onset. However, it was associated with time from onset to first recognition of myoclonus, first recognition of periodic sharp-wave complexes on electroencephalogram, and progression to the akinetic mutism state. Mechanical ventilation was not performed for any patient. Because the total disease duration increased in cases with a slowly progressive clinical course as a natural outcome, we concluded that the most crucial factor contributing to the prolonged survival of Japanese sCJD patients was tube feeding once the akinetic mutism state had been reached.

    Intensive induction regimen followed by high-dose chemotherapy and autologous stem cell transplantation (auto-SCT) is frequently used to improve outcomes in patients with mantle-cell lymphoma. The comparative impact of conventional vs intensive induction regimen before transplantation is unknown. Forty-eight patients with mantle-cell lymphoma receiving SCT at our institution between January 2000 and December 2010 were included in this study. At the time of initial presentation, 43 (89.5%) had stage IV disease and 18 (37.5%) received more than one chemotherapy regimen before transplantation. Forty patients underwent auto-SCT and 7 had allogeneic SCT (allo-SCT); 1 patient had an allo-SCT for relapsed disease after auto-SCT. At the time of this analysis (median follow-up of 6 years from diagnosis and 4 years from transplantation), 40 patients (88%) were alive with a 5-year disease-free survival of 74.8%. Age, disease stage, number of regimens pre-SCT, pre-SCT disease status, and type of SCT had no impact on long-term outcomes. Importantly, there were no differences among the types of induction regimen on outcomes in this cohort receiving SCT. Based on our data, we believe that future studies should focus on strategies to prevent disease relapse rather than comparing induction regimens before stem cell transplantation.

    To assess if surgery provided survival benefit to patients with esophageal squamous cell carcinoma (SCC), we performed a retrospective review of 1230 patients who were newly diagnosed with stage T2-T4 esophageal SCC from 2007 to 2014 in our hospital. There were greater than 70% of patients with age under 65 years, and more than 85% were stage T3-T4 at the time of diagnosis. The median survival time was 1.06 year (95% CI 0.99–1.1 yrs). Survival analyses showed that survival time was significantly associated with age, T stage, clinical lymph node involvement and treatment modality (surgery versus definite chemoradiotherapy). Surgery still possessed a powerful impact on overall survival by multivariable analysis. Death risk of patients treated with curative surgery was significantly lower than those with definite chemoradiotherapy. Furthermore, for patients of stage T3N(+) and T4, surgery combined with (neo-)adjuvant treatment were significantly associated with higher survival rate than surgery alone or definite chemoradiotherapy. In conclusion, the patients who undergo surgery were significantly associated longer survival, therefore, curative resection should be considered for esophageal cancer patients who are medically fit for surgery. Moreover, combined with (neo-)adjuvant treatment is recommended for surgically resectable stage T3-T4 esophageal SCC. PMID:28383075

    Background: The aim of this study was to predict the survival rate of Iranian gastric cancer patients using the Cox proportional hazard and artificial neural network models as well as comparing the ability of these approaches in predicting the survival of these patients. Methods: In this historical cohort study, the data gathered from 436 registered gastric cancer patients who have had surgery between 2002 and 2007 at the Taleghani Hospital (a referral center for gastrointestinal cancers), Tehran, Iran, to predict the survival time using Cox proportional hazard and artificial neural network techniques. Results: The estimated one-year, two-year, three-year, four-year and five-year survival rates of the patients were 77.9%, 53.1%, 40.8%, 32.0%, and 17.4%, respectively. The Cox regression analysis revealed that the age at diagnosis, high-risk behaviors, extent of wall penetration, distant metastasis and tumor stage were significantly associated with the survival rate of the patients. The true prediction of neural network was 83.1%, and for Cox regression model, 75.0%. Conclusion: The present study shows that neural network model is a more powerful statistical tool in predicting the survival rate of the gastric cancer patients compared to Cox proportional hazard regression model. Therefore, this model recommended for the predicting the survival rate of these patients. PMID:23113076

    Purpose: Treatment of glioblastoma multiforme (GBM) continues to pose a significant therapeutic challenge, with most tumors recurring within the previously irradiated tumor bed. To improve outcomes, we must be able to identify and treat resistant cell populations. Rad51, an enzyme involved in homologous recombinational repair, leads to increased resistance of tumor cells to cytotoxic treatments such as radiotherapy. We hypothesized that Rad51 might contribute to GBM's apparent radioresistance and consequently influence survival. Methods and Materials: A total of 68 patients with an initial diagnosis of GBM were retrospectively evaluated; for 10 of these patients, recurrent tumor specimens were used to construct a tissue microarray. Rad51 protein expression was then correlated with the actual and predicted survival using recursive partitioning analysis. Results: Rad51 protein was elevated in 53% of the GBM specimens at surgery. The Rad51 levels correlated directly with survival, with a median survival of 15 months for patients with elevated Rad51 compared with 9 months for patients with low or absent levels of Rad51 (p = .05). At disease recurrence, 70% of patients had additional increases in Rad51 protein. Increased Rad51 levels at disease recurrence similarly predicted for improved overall survival, with a mean survival of 16 months from the second craniotomy compared with only 4 months for patients with low Rad51 levels (p = .13). Conclusion: Elevated levels of the double-stranded DNA repair protein Rad51 predicted for an increase survival duration in patients with GBM, at both initial tumor presentation and disease recurrence.

    Purpose: To construct a predictive model for survival of patients referred to the Rapid Response Radiotherapy Program using recursive partitioning (RP). Methods and Materials: We analyzed 16 factors characterizing patients with metastases at first referral to the Rapid Response Radiotherapy Program for palliative radiotherapy in 1999 for their effect on survival. They included age, primary cancer site, site of metastases, weight loss ({>=}10% during the past 6 months), Karnofsky performance status (KPS), interval from the first diagnosis of cancer to the first consultation at the Rapid Response Radiotherapy Program, analgesic consumption within the previous 24 h, and the nine symptom scores from the Edmonton Symptom Assessment Scale. We used RP to develop a predictive model of survival for patients referred in 1999, followed by temporal validation using patients referred in 2000, and external validation using patients referred in 2002 to another institution. Results: The model was able to separate patients into three groups with different durations of survival that were defined by (1) KPS >60; (2) KPS {<=}60 with bone metastases only; and (3) KPS {<=}60 with other metastases. The model performed moderately well when applied to the validation sets, but a major limitation was that it led to an unequal distribution of patients, with a small proportion of patients in the intermediate group. Conclusion: We have demonstrated that RP can be used to predict the survival of patients with advanced cancer. However, this model has no advantages compared with our published prognostic models that use the survival prediction scores and number of risk factors.

    Purpose: To develop nomograms for predicting the overall survival (OS) and relapse-free survival (RFS) in patients with extrahepatic bile duct cancer undergoing adjuvant chemoradiation therapy after curative resection. Methods and Materials: From January 1995 through August 2006, a total of 166 consecutive patients underwent curative resection followed by adjuvant chemoradiation therapy. Multivariate analysis using Cox proportional hazards regression was performed, and this Cox model was used as the basis for the nomograms of OS and RFS. We calculated concordance indices of the constructed nomograms and American Joint Committee on Cancer (AJCC) staging system. Results: The OS rate at 2 years and 5 years was 60.8% and 42.5%, respectively, and the RFS rate at 2 years and 5 years was 52.5% and 38.2%, respectively. The model containing age, sex, tumor location, histologic differentiation, perineural invasion, and lymph node involvement was selected for nomograms. The bootstrap-corrected concordance index of the nomogram for OS and RFS was 0.63 and 0.62, respectively, and that of AJCC staging for OS and RFS was 0.50 and 0.52, respectively. Conclusions: We developed nomograms that predicted survival and recurrence better than AJCC staging. With caution, clinicians may use these nomograms as an adjunct to or substitute for AJCC staging for predicting an individual's prognosis and offering tailored adjuvant therapy.

    At a recent in-house meeting at the European Association for Cardiothoracic Surgery (EACTS) headquarters in Windsor, the Chairs of the four domains were asked by the President to present their perception of the next 5 years in their respective domains. This review represents a distillation of our discussions on adult cardiac surgery. Advances in technology and imaging are having a radical effect on the working lives of surgeons. In clinical practice, the growth of heart teams and the breaking down of artificial barriers between specialities are altering the way we practice for the better. We see the development of hybrid approaches to many areas such as coronary artery surgery and operations on the thoracic aorta. These changes require careful analysis to ensure that they produce better outcomes that are also cost-effective. All health-care systems are at breaking point, and it is our responsibility to harness new technology to benefit our patients. This is all part of placing the patient at the centre of our activities. Hence, we see the involvement of patients in the design and analysis of clinical trials, which also require great mutual trust and cooperation between surgeons in different countries. Because of the dramatic changes in the pattern of working, we have had to alter our patterns of training and education, and we will continue to make significant innovations in the future. These are exciting challenges that will keep us all busy for the next 5 years at least.

    Purpose: Patients with pulmonary metastases (PM) from soft-tissue sarcomas (STS) have historically been treated with surgery and/or chemotherapy. Since 2001, we have treated PM with stereotactic body radiation therapy (SBRT). We postulated that SBRT for PM from STS would yield excellent local control (LC) and overall survival (OS). Methods and Materials: Fifty-two patients with PM from STS, diagnosed between 1990 and 2006 at University of Rochester, were retrospectively reviewed. Most patients received multimodality treatment comprising of surgery, chemotherapy, and/or radiation. SBRT used the Novalis ExacTrac patient positioning platform, vacuum bag immobilization, and relaxed end-expiratory breath hold techniques. Results: Leiomyosarcoma (23%), malignant fibrous histiocytoma (19%), and synovial sarcoma (15%) were the most common histologies. Forty-eight percent initially presented with PM, whereas 52% developed PM at a median of 0.7 (0.3-7.3) years after initial diagnosis. Median follow-up from diagnosis of PM was 0.9 (0.3-7.3) years. Fifteen patients underwent SBRT to 74 lesions. Median number of lesions treated was 4 (1-16) per patient and 3.5 (1-6) per session. Preferred dose and fractionation was 50 Gy in 5 Gy fractions. Three-year LC was 82%. No patients experienced Grade {>=}3 toxicity. Median OS was 2.1 (0.8-11.5) years for patients treated with SBRT, and 0.6 (0.1-7.8) years for those who never received SBRT (p = 0.002). Conclusions: SBRT provides excellent LC of PM and may extend OS. SBRT should be considered for all patients with PM from STS, particularly those who are not surgical candidates. Further investigation is warranted to establish criteria for the use of SBRT for STS patients with PM.

    Purpose. The association between transarterial chemoembolization- (TACE-) induced HCC tumor necrosis measured by the modified Response Evaluation Criteria In Solid Tumors (mRECIST) and patient survival is poorly defined. We hypothesize that survival will be superior in HCC patients with increased TACE-induced tumor necrosis. Materials and Methods. TACE interventions were retrospectively reviewed. Tumor response was quantified via dichotomized (responders and nonresponders) and the four defined mRECIST categories. Results. Median survival following TACE was significantly greater in responders compared to nonresponders (20.8 months versus 14.9 months, p = 0.011). Survival outcomes also significantly varied among the four mRECIST categories (p = 0.0003): complete, 21.4 months; partial, 20.8; stable, 16.8; and progressive, 7.73. Only progressive disease demonstrated significantly worse survival when compared to complete response. Multivariable analysis showed that progressive disease, increasing total tumor diameter, and non-Child-Pugh class A were independent predictors of post-TACE mortality. Conclusions. Both dichotomized (responders and nonresponders) and the four defined mRECIST responses to TACE in patients with HCC were predictive of survival. The main driver of the survival analysis was poor survival in the progressive disease group. Surprisingly, there was small nonsignificant survival benefit between complete, partial, and stable disease groups. These findings may inform HCC treatment decisions following first TACE.

    Between December 2005 and October 2009, FDA approved six targeted therapies shown to significantly extend survival for advanced renal cell carcinoma (RCC) patients in clinical trials. This study aimed to examine changes in survival between the pretargeted and targeted therapy periods in advanced RCC patients in a real-world setting. Utilizing the 2000-2010 SEER Research files, a pre-post study design with a contemporaneous comparison group was employed to examine differences in survival outcomes for patients diagnosed with advanced RCC (study group) or advanced prostate cancer (comparison group, for whom no significant treatment innovations happened during this period) across the pretargeted therapy era (2000-2005) and the targeted therapy era (2006-2010). RCC patients diagnosed in the targeted therapy era (N = 6439) showed improved survival compared to those diagnosed in the pretargeted therapy era (N = 7231, hazard ratio (HR) for all-cause death: 0.86, P < 0.01), while the change between the pre-post periods was not significant for advanced prostate cancer patients (HR: 0.97, P = 0.08). Advanced RCC patients had significantly larger improvements in overall survival compared to advanced prostate cancer patients (z = 4.31; P < 0.01). More detailed year-to-year analysis revealed greater survival improvements for RCC in the later years of the posttargeted period. Similar results were seen for cause-specific survival. Subgroup analyses by nephrectomy status, age, and gender showed consistent findings. Patients diagnosed with advanced RCC during the targeted therapy era had better survival outcomes than those diagnosed during the pretargeted therapy era. Future studies should examine the real-world survival improvements directly associated with targeted therapies.

    Background Endometrial cancer is the most common gynaecologic malignancy among females worldwide. The purpose of this study was to determine the median survival time of endometrial cancer patients at the Hospital Universiti Sains Malaysia (USM). Methods A list of 121 endometrial cancer cases registered at Hospital USM between 2000 until 2011 was retrospectively reviewed. The survival time of the endometrial cancer patients was estimated by Kaplan-Meier survival analysis. Log-rank tests were performed to compare the survival of the patients based on socio-demographics and clinical presentation. Results Only 108 patients, 87.0%, were included who were of Malay ethnicity. Previous history included menopause in 67.6% of patients and diabetes mellitus in 39.8% of patients; additionally, 63.4% of patients were nulliparous. Tumour staging was as follows: 24.5% stage I, 10.8% stage II, 26.5% stage III and 38.2% stage IV. The overall median survival time of the endometrial cancer patients was 70.20 months (95% confidence interval (CI): 51.79, 88.61). The significant factors were age, the presence of lymphovascular invasion and treatment received. Conclusion The overall survival of endometrial cancer was low. A prospective study needs to be carried out to discover more effective and accurate tests for the early detection of endometrial cancer. PMID:28090178

    Primary pulmonary hypertension (PPH) is a progressive disease with high mortality. Administration of i.v. epoprostenol has demonstrated improved exercise tolerance, haemodynamics, and survival. The orally active, dual endothelin receptor antagonist bosentan improves exercise endurance, haemodynamics, and functional class over the short term. To determine the effect of first-line bosentan therapy on survival, this study followed 169 patients with PPH treated with bosentan in two placebo-controlled trials and their extensions. Data on survival and alternative treatments were collected from September 1999 (start of the first placebo-controlled study) to December 31, 2002. Observed survival up to 36 months was reported as Kaplan-Meier estimates and compared with predicted survival as determined for each patient by the National Institutes of Health Registry formula. Kaplan-Meier survival estimates were 96% at 12 months and 89% at 24 months. In contrast, predicted survival was 69% and 57%, respectively. In addition, at the end of 12 and 24 months, 85% and 70% of patients, respectively, remained alive and on bosentan monotherapy. Factors that predicted a worse outcome included World Health Organization Functional Class IV and 6-min walk distance below the median (358 m) at baseline. First-line bosentan therapy was found to improve survival in patients with advanced primary pulmonary hypertension.

    Within the past decades, major advances in therapy for chronic myelocytic leukemia, including allogeneic hematopoietic stem cell transplantation, interferon therapy, and, more recently, also therapy with the tyrosine kinase inhibitor imatinib, have entered clinical practice. The impact of these advances on long-term survival on the population level should be disclosed as timely as possible. We estimated trends in age specific 5- and 10-year relative survival of chronic myelocytic leukemia patients in the United States from 1990-1992 to 2002-2004. Our analysis is based on records from 8,329 patients aged 15 years or older with a first diagnosis of chronic myelocytic leukemia included in the 1973-2004 data base of the Surveillance, Epidemiology, and End Results Program. Period analysis was used to disclose recent developments with minimum delay. Overall, 5-year relative survival increased from 27 to 49%, and 10-year relative survival increased from 9.5 to 34% between 1990-92 and 2002-04. The increase was most dramatic for younger patients, with 10-year relative survival increasing from 16 to 72% in age group 15-44 years, from 12 to 54% in age group 45-54 years, and from 8 to 34% in age group 55-64 years (p<0.0001 in all cases). Improvements were more modest and not statistically significant, and survival remained at much lower levels among age groups 65-74 and 75+ years. Our analysis discloses a dramatic recent increase in long-term survival of younger patients with chronic myelocytic leukemia which most likely reflects rapid dissemination of advances in therapy on the population level.

    Objectives The aim of this study was to investigate somatic mutations in the D-loop of mitochondrial DNA (mtDNA) and their impact on survival in oral squamous cell carcinoma patients. Materials and Methods Surgical specimen confirmed by pathological examination and corresponding non-cancerous tissues were collected from 120 oral squamous cell carcinoma patients. The sequence in the D-loop of mtDNA from non-cancerous tissues was compared with that from paired cancer samples and any sequence differences were recognized as somatic mutations. Results Somatic mutations in the D-loop of mtDNA were identified in 75 (62.5%) oral squamous cell carcinoma patients and most of them occurred in the poly-C tract. Although there were no significant differences in demographic and tumor-related features between participants with and without somatic mutation, the mutation group had a better survival rate (5 year disease-specific survival rate: 64.0% vs. 43.0%, P = 0.0266). Conclusion Somatic mutation in D-loop of mtDNA was associated with a better survival in oral squamous cell carcinoma patients. PMID:25906372

    Background Several unfavorable prognostic factors have been proposed for peripheral cholangiocarcinoma (PCC) in patients undergoing hepatectomy, including gross type of tumor, vascular invasion, lymph node metastasis, a high carbohydrate antigen 19-9 level, and a positive resection margin. However, the clinical effect of a positive surgical margin on the survival of patients with PCC after hepatectomy still needs to be clarified due to conflicting results. Methods A total of 224 PCC patients who underwent hepatic resection with curative intent between 1977 and 2007 were retrospectively reviewed. Eighty-nine patients had a positive resection margin, with 62 having a microscopically positive margin and 27 a grossly positive margin (R2). The clinicopathological features, outcomes, and recurrence pattern were compared with patients with curative hepatectomy. Results PCC patients with hepatolithiasis, periductal infiltrative or periductal infiltrative mixed with mass-forming growth, higher T stage, and more advanced stage tended to have higher positive resection margin rates after hepatectomy. PCC patients who underwent curative hepatectomy had a significantly higher survival rate than did those with a positive surgical margin. When PCC patients underwent hepatectomy with a positive resection margin, the histological grade of the tumor, nodal positivity, and chemotherapy significantly affected overall survival. Locoregional recurrence was the most common pattern of recurrence. Conclusion A positive resection margin had an unfavorable effect on overall survival in PCC patients undergoing hepatectomy. In these patients, the prognosis was determined by the biology of the tumor, including differentiation and nodal positivity, and chemotherapy increased overall survival. PMID:25552905

    The indications for delaying the start of dialysis have revived interest in low-protein diets (LPDs). In this observational prospective study, we enrolled all patients with chronic kidney disease (CKD) who followed a moderately restricted LPD in 2007–2015 in a nephrology unit in Italy: 449 patients, 847 years of observation. At the start of the diet, the median glomerular filtration rate (GFR) was 20 mL/min, the median age was 70, the median Charlson Index was 7. Standardized mortality rates for the “on-diet” population were significantly lower than for patients on dialysis (United States Renal Data System (USRDS): 0.44 (0.36–0.54); Italian Dialysis Registry: 0.73 (0.59–0.88); French Dialysis Registry 0.70 (0.57–0.85)). Considering only the follow-up at low GFR (≤15 mL/min), survival remained significantly higher than in the USRDS, and was equivalent to the Italian and French registries, with an advantage in younger patients. Below the e-GFR of 15 mL/min, 50% of the patients reached a dialysis-free follow-up of ≥2 years; 25% have been dialysis-free for five years. Considering an average yearly cost of about 50,000 Euros for dialysis and 1200 Euros for the diet, and different hypotheses of “spared” dialysis years, treating 100 patients on a moderately restricted LPD would allow saving one to four million Euros. Therefore, our study suggests that in patients with advanced CKD, moderately restricted LPDs may allow prolonging dialysis-free follow-up with comparable survival to dialysis at a lower cost.

    To assess the prognostic value of primary tumor metabolic activity in patients with high-grade bone sarcomas (BS) or soft tissue sarcomas (STS) using F-18 FDG PET/CT. A single-site, retrospective study including 92 patients with high-grade BS or STS. Pretreatment F-18 FDG PET/CT scan was performed. Clinical data were registered. Accuracy of maximum standardized uptake value of primary tumor (SUVmax) and tumor-to-background (T/B) uptake ratio as prognostic variables and identification of cut-off values to group patients were determined. Kaplan-Meier survival estimates and log-rank test were used to compare survival distributions. Prognostic variables were assessed using Cox proportional hazards regression analysis. Forty-one of 92 patients died during follow-up (45%). Average survival was 6.5 years (95% CI 5.8-7.3 years) and probability of 5-year survival was 52%. Accuracy of SUVmax and T/B uptake ratio as prognostic variables in all patients and during subgroup analysis of patients with STS was significant. No significant results for AUCs were registered in patients with BS. Surgery was independently prognostic for survival throughout multivariate regression analysis of all patients (P = 0.001, HR 3.84) and subgroup analysis (BS: P = 0.02, HR 11.62; STS: P = 0.005, HR 4.13). SUVmax was significant as prognostic variable in all patients (P = 0.02, HR 3.66) and in patients with STS (P = 0.007, HR 3.75). No significant results were demonstrated for T/B uptake ratio. Estimation of primary tumor metabolic activity with pretherapeutic SUVmax using F-18 FDG PET/CT demonstrates independent properties beyond histologic grading for prediction of survival in patients with high-grade STS, but not with high-grade BS.

    High-risk myelodysplastic syndrome (MDS) patients have usually a less favorable outcome after intensive treatment compared with de novo acute myeloid leukemia (AML) patients. This may reflect different disease-related and patient-related factors. The purpose of this analysis is to identify disease-specific prognostic factors and to develop prognostic scores for both patient groups. A total of 692 patients in the EORTC/GIMEMA AML-10 study and 289 patients in the CRIANT study received identical remission-induction and consolidation treatment. Estimated 5-year survival rate was 34 % in the AML-10 versus 27 % in the CRIANT study, and estimated disease-free survival was 40 % versus 28 %, respectively. In multivariate analysis, cytogenetic characteristics, white blood count, and age appeared prognostic for survival in both studies. French-American-British (FAB) subtype and performance status were prognostic in the AML-10 study only, whereas number of cytopenias and duration of antecedent hematologic disorder >6 months were prognostic in the CRIANT study only. The prognostic scores distinguish three groups with a 5-year survival rate of 54, 38, and 19 % in the AML-10 study versus 69, 37, and 5 % in the CRIANT study. The prognostic value of these scores has been validated on two external series. The new scoring systems form a practical tool to predict the outcome of individual MDS and AML patients treated with intensive antileukemic therapy.

    Hematopoietic cell transplantation (HCT) and prolonged chemotherapy are standard postremission strategies for adult acute lymphoblastic leukemia in first complete remission, but the optimal strategy remains controversial. There are no randomized trials of allogeneic HCT. In the present study, updated individual patient data were collected and analyzed from studies with information on availability of matched sibling donor (used to mimic randomization) and from randomized trials of autograft versus chemotherapy. Data from 13 studies including 2962 patients, excluding Philadelphia chromosome-positive patients, showed a survival benefit for having a matched sibling donor for patients < 35 years of age (OR = 0.79; 95% CI, 0.70-0.90, P = .0003) but not for those ≥ 35 years of age (OR = 1.01; 95% CI, 0.85-1.19, P = .9; heterogeneity P = .03) because of the higher absolute risk of nonrelapse mortality for older patients. No differences were seen by risk group. There was a trend toward inferior survival for autograft versus chemotherapy (OR = 1.18; 95% CI, 0.99-1.41; P = .06). No beneficial effect of autografting was seen compared with chemotherapy in this analysis. We conclude that matched sibling donor myeloablative HCT improves survival only for younger patients, with an absolute benefit of approximately 10% at 5 years. Improved chemotherapy outcomes and reduced nonrelapse mortality associated with allogeneic HCT may change the relative effects of these treatments in the future.

    Epidemiology and prognosis of complications related to allogeneic hematopoietic stem cell transplant (HSCT) recipients requiring admission to intensive care unit (ICU) have not been reassessed precisely in the past few years. We performed a retrospective single-center study on 318 consecutive HSCT patients (2009-2013), analyzing outcome and factors prognostic of ICU admission. Among these patients, 73 were admitted to the ICU. In all, 32 patients (40.3%) died in ICU, 46 at hospital discharge (63%) and 61 (83.6%) 1 year later. Survivors had a significantly lower sequential organ failure assessment (SOFA) score, serum lactate and bilirubin upon ICU admission. Catecholamine support, mechanical ventilation (MV) and/or renal replacement therapy during ICU stay, a delayed organ support and an active graft versus host disease (GvHD) significantly worsen the outcome. By multivariate analysis, the worsening of SOFA score from days 1 to 3, the need for MV and the occurrence of an active GvHD were predictive of mortality. In conclusion, the incidence of HSCT-related complications requiring an admission to an ICU was at 22%, with an ICU mortality rate of 44%, and 84% 1 year later. A degradation of SOFA score at day 3 of ICU, need of MV and occurrence of an active GvHD are main predictive factors of mortality.

    BACKGROUND Five-year survival rates among stage IIIA lung cancer patients range between 2% and 15%, and there is currently no consensus regarding optimal treatment approaches for these patients. The current investigation evaluated survival outcomes among stage IIIA lung cancer patients receiving 2 different treatment modalities, neoadjuvant chemotherapy followed by resection versus chemoradiation alone. MATERIAL AND METHODS This retrospective study is based on 127 patients attending the Lung Cancer Evaluation Center at Stony Brook Cancer Center between 2002 and 2014. Patients were treated either with neoadjuvant chemotherapy followed by resection or a regimen of chemoradiation alone. Kaplan-Meier curves were used to compare survival outcomes between groups and Cox proportional hazard models were used to evaluate treatment effects on survival, while adjusting for possible confounders. RESULTS Approximately one-fourth (n=33) of patients received neoadjuvant chemotherapy followed by surgery, whereas 94 patients received definitive chemoradiation. Patients in the surgical group were found to be significantly younger than those receiving chemoradiation alone (60.1 vs. 67.9 years, respectively; p=0.001). Five-year survival among patients receiving preoperative chemotherapy followed by resection was significantly higher than that among patients receiving chemoradiation alone (63% vs. 19%, respectively; p<0.001), whereas the hazard ratio (HR) was 3-4 times greater in the latter group (HR=3.77, 95% confidence interval=1.87, 7.61). CONCLUSIONS Findings from this study indicate that preoperative chemotherapy followed by resection can improve survival outcomes for stage IIIA lung cancer patients compared with chemoradiation alone. The results reflect a select surgical group of patients; thus, the data highlight the need to develop new therapies that may result in more patients being viable surgical candidates.

    The impact of nutritional status on survival among elderly esophageal squamous cell carcinoma (ESCC) patients undergoing radiotherapy is unclear. In this study, we aimed at validating the performance of the geriatric nutritional risk index (GNRI) in predicting overall survival time in elderly ESCC patients with radiotherapy. A retrospective cohort study was conducted on 239 ESCC patients aged 60 and over admitted consecutively from January 2008 to November 2014 in the Department of Radiotherapy, Henan Tumor Hospital (Affiliated Tumor Hospital of Zhengzhou University), Zhengzhou, Henan, China. All patients were subjected to nutritional screening using GNRI, and were followed for the occurrence of lymphatic node metastasis, radiation complication and mortality. The Kaplan–Meier method with Log-rank test was used to estimate survival curves. Univariable Cox regression analysis was used to identify variables associated with overall survival time. Among the 239 patients, 184 patients (76.9%) took no nutritional risk, 32 patients (13.4%) took moderate risk of malnutrition, and 23 patients (9.7%) took a high risk of malnutrition. Univariable Cox regression showed that both high nutritional risk group and moderate nutritional risk group were significantly less likely to survive than no nutritional risk patients (hazard ratio (HR) = 1.688, 95% confidence interval (CI) = 1.019–2.798 for moderate risk group, and HR = 2.699, 95% CI = 1.512–4.819 for high risk group, respectively). The GNRI is an independent prognostic factor for overall survival time in elderly ESCC patients with radiotherapy. A GNRI ≤98 can be suggested as an indicator of surviving less. PMID:27196126

    Purpose: We updated our previous report of a phase 2 trial using proton beam radiation therapy to deliver partial breast irradiation (PBI) in patients with early stage breast cancer. Methods and Materials: Eligible subjects had invasive nonlobular carcinoma with a maximal dimension of 3 cm. Patients underwent partial mastectomy with negative margins; axillary lymph nodes were negative on sampling. Subjects received postoperative proton beam radiation therapy to the surgical bed. The dose delivered was 40 Gy in 10 fractions, once daily over 2 weeks. Multiple fields were treated daily, and skin-sparing techniques were used. Following treatment, patients were evaluated with clinical assessments and annual mammograms to monitor toxicity, tumor recurrence, and cosmesis. Results: One hundred subjects were enrolled and treated. All patients completed the assigned treatment and were available for post-treatment analysis. The median follow-up was 60 months. Patients had a mean age of 63 years; 90% had ductal histology; the average tumor size was 1.3 cm. Actuarial data at 5 years included ipsilateral breast tumor recurrence-free survival of 97% (95% confidence interval: 100%-93%); disease-free survival of 94%; and overall survival of 95%. There were no cases of grade 3 or higher acute skin reactions, and late skin reactions included 7 cases of grade 1 telangiectasia. Patient- and physician-reported cosmesis was good to excellent in 90% of responses, was not changed from baseline measurements, and was well maintained throughout the entire 5-year follow-up period. Conclusions: Proton beam radiation therapy for PBI produced excellent ipsilateral breast recurrence-free survival with minimal toxicity. The treatment proved to be adaptable to all breast sizes and lumpectomy cavity configurations. Cosmetic results appear to be excellent and unchanged from baseline out to 5 years following treatment. Cosmetic results may be improved over those reported with photon

    To investigate the relationship between survival in colorectal cancer patients and the number of lymph nodes examined by a pathologist, previously attributed to stage migration, we used data from a cohort of 5174 colorectal cancer patients recruited between September 1991 and August 1994, and followed-up for 5 years. We selected cases with data present on all prognostic variables, and stratified them into three groups by number of nodes examined. We made a multivariate survival comparison using a Cox regression model. In all, there were 3592 cases with data present on all prognostic variables. Patients who had >10 nodes identified had a significant survival advantage over those who had 5–10 identified, who had in turn a similar advantage over those with 0–4 identified (P<0.001). This effect was present in the whole group and at all Dukes' stages, although statistically significant only in stages B (P=0.004) and C (P=0.019). The effect remained after adjustment in a Cox regression model in which the mean number of nodes taken out by each surgical firm did not predict survival. In a sub-group with data on lymphocytic infiltration into the primary tumour a survival advantage was noted in those with prominent rather than mild infiltration (P<0.001): the former also tended to have more nodes found (P=0.015). Stage migration alone cannot explain these results, as survival advantages are noted across the whole population independent of stage. Lymphocytic infiltration into the primary tumour is prognostically important, and is associated with the number of nodes found. Reactive enlargement of lymph nodes in the mesentery may make them easier to find, reflect immune response to the tumour, and thus indirectly impact upon survival. PMID:16969342

    SUMMARY Aims This retrospective study determined the survival of glioblastoma patients with or without pseudoprogression. Methods A total of 68 patients were included. Overall survival was compared between patients showing pseudoprogression (in most cases diagnosed using perfusion MRI with ferumoxytol) and in patients without pseudoprogession. MGMT methylation status was also analyzed in the pseudoprogression cases. Results Median survival in 24 (35.3%) patients with pseudoprogression was 34.7 months (95% CI: 20.3–54.1), and 13.4 months (95% CI: 11.1–19.5) in 44 (64.7%) patients without pseudoprogression (p < 0.0001). The longest survival was a median of 54.1 months in patients with combination of pseudoprogression and (MGMT) promoter methylation. Conclusion Pseudoprogression is associated with better outcome, especially if concurring with MGMT promoter methylation. Patients never diagnosed with pseudoprogression had poor survival. This study emphasizes the importance of differentiating tumor progression and pseudoprogression using perfusion MRI. PMID:25438810

    Laryngeal squamous cell carcinoma (LSCC) is one of the most common and aggressive malignancies of the upper digestive tract. The present study is a retrospective analysis of data from a prospective longitudinal study. A total of 170 male LSCC patients (average age, 60.75±10.082) at the First Affiliated Hospital of Xi'an Jiaotong University School of Medicine were recruited between January 2002 and April 2013 for this study. We assessed correlations between patient characteristics and survival, and sequenced genomic DNA from patient peripheral blood samples. We found that the single nucleotide polymorphisms (SNPs), rs11903757, with closest proximity to NABP1 and SDPR, and rs966423 in DIRC3, were associated with survival in LSCC patients. Median follow-up was 38 months (range 3–122) and median survival time was 48 months. LSCC patients with total laryngectomy, poor differentiation, T3-T4 stage, N1-N2 stage or III-IV TNM stage had reduced survival. This is the first study to demonstrate that the rs11903757 GT (HR=2.036; 95% CI, 1.071–3.872; p=0.030) and rs966423 TT (HR=11.677; 95% CI, 3.901–34.950; p=0.000) genotypes predict poor patient outcome. These polymorphisms may serve as useful clinical markers to predict patient survival, and to guide individual patient therapeutic decisions. PMID:27793000

    Acute myeloid leukaemia (AML) is mainly affecting elderly patients. Elderly patients are increasingly affected by impairment of functional status (FS). FS is of prognostic relevance for survival in different tumours. Data for patients with AML are rare. Within a prospective trial we recruited patients with newly diagnosed AML and measured FS by two different methods: Karnofsky performance status (KPS) and instrumental activities of daily living (IADL). Sixty-three patients aged 19-85 years (median 61.1) were included. Twenty-three had prior myelodisplastic syndrome (MDS), 7 favourable, 17 unfavourable karyotype. Fifty received induction chemotherapy, 13 palliative chemotherapy. Median survival was 15.2 months (95% CI, 10.8-22.3) in all patients. Age, cytogenetic risk group, and impaired KPS and IADL significantly influenced median survival in univariate analysis. Impairment of IADL was the single most predictive variable. In multivariate analysis, impairment of IADL Score (HR:4.3, 95% CI 1.7-10.5, P = 0.001) and of KPS (HR:4.8, 95% CI 1.9-12.3, P = 0.001), and unfavourable cytogenetic risk group (HR:6.0, 95% CI 2.5-14.3, P < 0.001) significantly predicted median survival. In patients with AML, FS and not age is a major predictor of survival. The influence of FS is independent from cytogenetic risk group. IADL measurement adds information to KPS. The results have to be confirmed in a large sample of patients.

    This study was designed to examine the prediction of pretreatment circulating bilirubin and cholesterol for overall survival in 459 advanced non-small-cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations. Circulating total bilirubin, direct bilirubin (DB), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were measured at baseline. The mean age (standard deviation) of all study patients was 58.7 (10.5) years, and 42.9% of them was males. Ever smokers accounted for 27.0% and lung adenocarcinoma for 90.4%. The median follow-up time and survival time were 29.5 and 34.9 months, respectively. Patients with higher DB had a 1.68-fold increased risk of death compared with patients with lower DB (hazard ratio [HR] = 1.68, 95% confidence interval [CI]: 1.22-2.30, p = 0.001), while patients with higher TC were at a 63% reduced risk of death compared with patients with lower TC (HR = 0.37, 95% CI: 0.20-0.67, p = 0.001). As for HDL-C, patients with higher levels had the risk of death reduced by 46% (HR = 0.54, 95% CI: 0.29-1.00, p = 0.049) compared with patients with lower levels. After the Bonferroni correction, only DB and TC were significantly associated with NSCLC survival. Our findings demonstrate for the first time that pretreatment DB was identified as a significant risk factor, yet TC as a protective factor, for overall survival in NSCLC patients with EGFR mutations.

    Socioeconomic status (SES) has been linked to worse end-stage kidney disease survival. The effect of SES on survival on chronic dialysis, including the impact of transplantation, was examined. A retrospective, observational study investigated the association of SES with dialysis patient survival, with censoring at time of transplantation. Adult patients commencing dialysis from 1990 to 2009 in an Irish tertiary center received a spatial SES score using the 2011 Pobal Haase-Pratschke Deprivation Index and were compared by quartile. Cox proportional hazard models and Kaplan-Meier survival analysis examined any association of SES with survival. The 1794 patients included had a median follow-up of 3.8 years. Patients in the lowest SES area quartile were significantly younger than the highest, mean age 56.7 vs. 59 years, P = 0.006, respectively. There was no association between SES area score and survival in an unadjusted model (hazard ratio [HR] 1.00, 95% confidence interval [CI] 0.99-1.01). Survival in the highest SES area quartile was superior to the lowest SES in a multivariable adjusted model including age, gender, and dialysis modality (HR 0.83, 95% CI 0.70-0.99, P = 0.04). These results were only mildly attenuated by censoring at time of transplantation (highest SES area quartile deprived vs. lowest SES area quartile, HR 0.85, 95% CI 0.70-1.03, P = 0.09). Superior patient survival was identified in the highest SES areas compared with the lowest following age-adjusted analyses, despite the older population in the most affluent areas. Further research should focus on identifying modifiable targets for intervention that account for this socioeconomic-related survival advantage.

    The aim of the study was to investigate the effect of intravenous infusions of adenosine 5'-triphosphate (ATP) on nutritional status and survival in preterminal cancer patients. Ninety-nine preterminal cancer patients (estimated life expectancy 1-6 months) with mixed tumor types were randomly allocated to receive either intravenous ATP weekly (8-10 h/week, maximum 50 microg/kg/min) for 8 weeks, or no ATP (control group). Nutritional status parameters were assessed until 8 weeks, and analyzed by repeated-measures analysis of covariance. Cox proportional hazards models were fitted to assess the effect of ATP on short-term (0-8 weeks) and long-term (0-6 months) survival. Fifty-one patients were randomized to ATP and 48 to the control group. Results showed a significant favorable effect of ATP on triceps skin fold thickness [between-group difference per 8 weeks 1.76 mm, 95% confidence interval (CI): 0.48-3.12 mm; P = 0.009] and on short-term survival [0-8 weeks hazard ratio (HR): 0.40, 95% CI: 0.17-0.95; P = 0.037]. In weight-stable patients and in lung cancer patients, long-term survival (0-6 months) was also significantly better in ATP-treated patients (weight-stable patients HR: 0.40, 95% CI: 0.19-0.83; P = 0.014; patients with lung cancer: HR: 0.35, 95% CI: 0.14-0.88; P = 0.025). In conclusion, in this population of preterminal cancer patients, ATP infusions, at the dose and schedule studied, had a favorable effect on triceps skin fold thickness and survival, especially in weight-stable patients and patients with lung cancer. Larger studies are warranted to confirm these findings and to further define the effect of ATP on tumor growth and survival.

    To determine the receipt and impact of adjuvant therapy on overall survival (OS) for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4807 patients with AA diagnosed from 2004 to 2013 who underwent surgery were identified. 3243 (67.5 %) received adjuvant chemoRT, 525 (10.9 %) adjuvant radiotherapy (RT) alone, 176 (3.7 %) adjuvant chemotherapy alone and 863 (18.0 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 (p = 0.022), were ≤ 50 years (p < 0.001), were male (p = 0.043), were Asian or White race (p < 0.001), had private insurance (p < 0.001), had income ≥$38,000 (p < 0.001), or underwent total resection (p < 0.003). Those who received adjuvant chemoRT had significantly better 5-year OS than the other adjuvant treatment types (41.8 % vs. 31.2 % vs. 29.8 % vs. 27.4 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age at diagnosis. Of those undergoing adjuvant chemoRT, those receiving ≥59.4 Gy had significantly better 5-year OS than those receiving <59.4 Gy (44.4 % vs. 25.9 %, p < 0.001). There was no significant difference in OS when comparing 59.4 Gy to higher RT doses. On multivariate analysis, receipt of adjuvant chemoRT, age at diagnosis, extent of disease, and insurance status were independent prognostic factors for OS. Adjuvant chemoRT is an independent prognostic factor for improved OS in AA and concomitant chemoRT should be considered for all clinically suitable patients who have undergone surgery for the disease.

    AIM To determine whether diabetes mellitus (DM) affects prognosis/recurrence after liver transplantation (LT) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS A retrospective study was conducted between January 2000 and August 2013 on 1631 patients with HBV-related HCC who underwent LT with antiviral prophylaxis. Patient data were obtained from the China Liver Transplant Registry (https://www.cltr.org/). To compare the outcomes and tumor recurrence in the HBV-related HCC patients with or without DM, statistical analyses were conducted using χ2 tests, Mann-Whitney tests, the Kaplan-Meier method, log-rank tests and multivariate step-wise Cox regression analysis. RESULTS Univariate analysis of 1631 patients who underwent LT found overall 1-, 3- and 5-year survival rates of 79%, 73% and 71% respectively in the DM patients, and 84%, 78% and 76% in the non-DM patients respectively. Overall survival rate differences after LT between the two groups were significant (P = 0.041), but recurrence-free survival rates were not (P = 0.096). By stratified analysis, the overall survival rates in DM patients for age > 50 years (P = 0.002), the presence of vascular invasion (P = 0.096), tumors ≤ 3 cm (P = 0.047), two to three tumor nodules (P = 0.007), Child-Pugh grade B (P = 0.018), and pre-LT alanine aminotransferase levels between 40 and 80 IU/L (P = 0.017) were significantly lower than in non-DM patients. Additionally, serum α-fetoprotein level > 2000 ng/mL (P = 0.052) was associated with a significant survival difference trend between DM and non-DM patients. Multivariate analysis showed that the presence of DM (P < 0.001, HR = 1.591; 95%CI: 1.239-2.041) was an independent predictor associated with poor survival after LT. CONCLUSION HBV-related HCC patients with DM have decreased long-term overall survival and poor LT outcomes. Prevention strategies for HCC patients with DM are recommended. PMID:27920478

    The aim of this study was to evaluate female urethral cancer (UCa) patients treated and followed-up during a time period spanning more than 20 yr at single institution in Korea. We reviewed medical records of 21 consecutive patients diagnosed with female UCa at our institution between 1991 and 2012. After exclusion of two patients due to undefined histology, we examined clinicopathological variables, as well as survival outcomes of 19 patients with female UCa. A Cox proportional hazards ratio model was used to identify significant predictors of prognosis according to variables. The median age at diagnosis was 59 yr, and the median follow-up duration was 87.0 months. The most common initial symptoms were voiding symptoms and blood spotting. The median tumor size was 3.4 cm, and 55% of patients had lesions involving the entire urethra. The most common histologic type was adenocarcinoma, and the second most common type was urothelial carcinoma. Fourteen patients underwent surgery, and 7 of these patients received adjuvant radiation or systemic chemotherapy. Eleven patients experienced tumor recurrence after primary therapy. Patients with high stage disease, advanced T stage (≥T3), and positive lymph nodes had worse survival outcomes compared to their counterparts. Particularly, lymph node positivity and advanced T stage were significant predictive factors for all survival outcomes. Tumor location was the only significant predictor for recurrence-free survival. Although our study included a small number of patients, it conveys valuable information about this rare female urologic malignancy in a Korean population.

Design Population-based prospective cohort study. Setting 34 general practices in East Anglia, UK, delivering organised diabetes care. Participants 478 patients recently diagnosed with type 2 diabetes aged between 40 and 69 years enrolled in the ADDITION-Plus trial. Main outcome measures Self-reported and objectively measured health behaviours (diet, physical activity, smoking status), CVD risk factor levels (blood pressure, lipid levels, glycated haemoglobin, body mass index, waist circumference) and modelled 10-year CVD risk. Results Better experiences of PCC early in the course of living with diabetes were not associated with meaningful differences in self-reported physical activity levels including total activity energy expenditure (β-coefficient: 0.080 MET h/day (95% CI 0.017 to 0.143; p=0.01)), moderate-to-vigorous physical activity (β-coefficient: 5.328 min/day (95% CI 0.796 to 9.859; p=0.01)) and reduced sedentary time (β-coefficient: −1.633 min/day (95% CI −2.897 to −0.368; p=0.01)). PCC was not associated with clinically meaningful differences in levels of high-density lipoprotein cholesterol (β-coefficient: 0.002 mmol/L (95% CI 0.001 to 0.004; p=0.03)), systolic blood pressure (β-coefficient: −0.561 mm Hg (95% CI −0.653 to −0.468; p=0.01)) or diastolic blood pressure (β-coefficient: −0.565 mm Hg (95% CI −0.654 to −0.476; p=0.01)). Over an extended follow-up of 5 years, we observed no clear evidence that PCC was associated with self-reported, clinical or biochemical outcomes, except for waist circumference (β-coefficient: 0.085 cm (95% CI 0.015 to 0.155; p=0.02)). Conclusions We found little evidence that experience of PCC early in the course of diabetes was associated with clinically important changes in health

    Hepatocellular carcinoma (HCC) is one of the most common types of cancer worldwide. Only a minority of HCC patients benefit from curative therapies, such as surgical resection, liver transplantation, or percutaneous treatment, since the majority of HCCs are diagnosed at intermediate or advanced stages. To determine whether transarterial chemoembolization (TACE) affects survival in patients with unresectable HCC, we conducted a case-controlled study, investigating 129 patients diagnosed with intermediate- or advanced-stage HCC, classified according to the Barcelona Clinic Liver Cancer staging system. Of these 129 patients, 102 received TACE and 27 received symptomatic treatment alone. The primary follow-up endpoint was survival. The association of TACE with survival was estimated with the Kaplan-Meier method. Survival was significantly higher in the chemoembolization group compared to that in the symptomatic treatment group. The estimated 1-, 2- and 3-year survival rates were 61.8, 34.0 and 24.3% for the chemoembolization group and 51.9, 9.9 and 0% for the symptomatic treatment group (P<0.001). TACE was shown to significantly improve survival and is an effective form of treatment for patients with unresectable HCC. PMID:24649333

    P53 mutations are associated with invasive tumors in mouse models. We assessed the p53mutations and survival in patients with advanced cancer treated in the Phase I Program. Of 691 tested patients, 273 (39.5%) had p53 mutations. Patients with p53 mutations were older (p<.0001) and had higher numbers of liver metastases (p=.005). P53 mutations were associated with higher numbers of other aberrations; PTEN (p=.0005) and HER2 (p=.003)aberrations were more common in the p53 mutation group. No survival difference was observed between patients with p53 mutations and those with wild-type p53. In patients with wild-type p53 and other aberrations, patients treated with matched-therapy against the additional aberrations had longer survival compared to those treated with non-matched-therapy or those who received no therapy (median survival, 26.0 vs. 11.8 vs. 9.8 months, respectively; p= .0007). Results were confirmed in a multivariate analysis (p= .0002). In the p53 mutation group with additional aberrations, those who received matched-therapy against the additional aberrations had survival similar to those treated with non-matched-therapy or those who received no therapy (p=.15). In conclusion, our results demonstrated resistance to matched-targeted therapy to the other aberrations in patients with p53 mutations and emphasize the need to overcome this resistance.

    Objective. To analyse survival in patients with pulmonary tuberculosis (PTB) and factors associated with such survival. Design. Study of a cohort of patients aged over 14 years diagnosed with PTB from January 1, 1998 to July 31, 2005. During 2004-2006 a home visit was made to each patient and, during 2008-2009, they were visited again. During these visits a follow-up interview was administered; when the patient had died, a verbal autopsy was conducted with family members. Statistical analysis consisted of survival tests, Kaplan-Meier log-rank test and Cox regression. Results. Of 305 studied patients, 68 had died due to PTB by the time of the first evaluation, 237 were followed-up for a second evaluation, and 10 of them had died of PTB. According to the Cox regression, age (over 45 years) and treatment duration (under six months) were associated with a poorer survival. When treatment duration was excluded, the association between poorer survival with age persisted, whereas with having been treated via DOTS strategy, was barely significant. Conclusions. In the studied area it is necessary that patients receive a complete treatment scheme, and to give priority to patients aged over 45 years.

    Objective. To analyse survival in patients with pulmonary tuberculosis (PTB) and factors associated with such survival. Design. Study of a cohort of patients aged over 14 years diagnosed with PTB from January 1, 1998 to July 31, 2005. During 2004–2006 a home visit was made to each patient and, during 2008-2009, they were visited again. During these visits a follow-up interview was administered; when the patient had died, a verbal autopsy was conducted with family members. Statistical analysis consisted of survival tests, Kaplan-Meier log-rank test and Cox regression. Results. Of 305 studied patients, 68 had died due to PTB by the time of the first evaluation, 237 were followed-up for a second evaluation, and 10 of them had died of PTB. According to the Cox regression, age (over 45 years) and treatment duration (under six months) were associated with a poorer survival. When treatment duration was excluded, the association between poorer survival with age persisted, whereas with having been treated via DOTS strategy, was barely significant. Conclusions. In the studied area it is necessary that patients receive a complete treatment scheme, and to give priority to patients aged over 45 years. PMID:22701170

    Background: In patients with advanced renal dysfunction undergoing maintenance hemodialysis, glycated albumin (GA) levels may be more representative of blood glucose levels than hemoglobin A1C levels. The aim of this study was to determine the predictive power of GA levels on long-term survival in hemodialysis patients. Methods: A total of 176 patients with a mean age of 68.2 years were enrolled. The median duration of follow-up was 51.0 months. Receiver-operating characteristic curve analysis was utilized to determine the optimal cutoff value. We examined the cumulative survival rate by Kaplan-Meier estimates and the influence of known survival factors with the multivariate Cox proportional-hazard regression model. Results: In the whole patient group, cumulative survival in the low GA group was better than in the high GA group (p=0.030), with more prominence in those aged <70 years (p=0.029). In subgroup analysis, both diabetic (DM) and non-DM patients with low GA had a better cumulative survival compared with those with high GA. The risk of mortality increased by 3.0% for each 1% increase in serum GA level in all patients undergoing hemodialysis. Conclusions: In addition to serving as a glycemic control marker, GA levels may be useful for evaluating the risk of death in both DM and non-DM patients on hemodialysis. PMID:27226780

    Background The impact of recent medical advances on disease presentation, extent of surgery, and disease specific survival (DSS) for patients with medullary thyroid cancer (MTC) is unclear. Methods We used the Surveillance, Epidemiology, and End Results registry to compare trends over three time periods, 1983–1992, 1993–2002, and 2003–2012. Results There were 2,940 patients diagnosed with MTC between 1983 and 2012. The incidence of MTC increased during this time period from 0.14 to 0.21 per 100,000 population, and mean age at diagnosis increased from 49.8 to 53.8 (p<0.001). The proportion of tumors ≤1cm also increased from 11.4% in 1983–1992, 19.6% in 1993–2002, to 25.1% in 2003–2012 (p<0.001), but stage at diagnosis remained constant (p=0.57). In addition, the proportion of patients undergoing a total thyroidectomy and lymph node dissection increased from 58.2% to 76.5% during the study period (p<0.001). In the most recent time interval, 5-year DSS improved from 86% to 89% in all patients (p<0.001), but especially for patients with regional (82% to 91%, p=0.003) and distant (40% to 51%, p=0.02) disease. Conclusions These data demonstrate that the extent of surgery is increasing for patients with MTC. DSS is also improving, primarily in patients with regional and distant disease. PMID:27842913

  4. Survival and mitochondrial function in septic patients according to mitochondrial DNA haplogroup

    PubMed Central

    2012-01-01

    Introduction We recently found that platelet cytochrome c oxidase (COX) activities and quantities in 6-month-survival septic patients are significantly higher than those of patients who died before 6 months. Other studies suggested that the mitochondrial DNA (mtDNA) genotype could play a major role in sepsis survival. Given that COX catalytic subunits are encoded by mtDNA, the objective of the present study was to explore whether mtDNA population genetic variation could affect COX activity and quantity and favors sepsis survival. Methods A prospective, multicenter, observational study was carried out in six Spanish ICUs. We included 96 patients with severe sepsis. We determined the mtDNA haplogroup, the COX specific activity/citrate synthase specific activity (COXa/CSa) ratio and the COX quantity/citrate synthase specific activity (COXq/CSa) ratio in circulating platelets at the time of diagnosis, day 4 and day 8. We used survival at 1 and 6 months as endpoints. Results Patients with the JT mtDNA haplogroup (n = 15) showed higher COXq/CSa ratio at day 4 (P = 0.04) and day 8 (P = 0.02) than those with other haplogroups (n = 81). Logistic regression analysis showed that the JT mtDNA haplogroup (odds ratio = 0.18; 95% confidence interval = 0.04 to 0.94; P = 0.04) and COXq/CSa ratio (odds ratio = 0.53; 95% confidence interval = 0.30 to 0.93; P = 0.03) were associated with 1-month survival after controlling for age and lactic acid levels. Conclusions The novel findings of our study are that 1-month surviving septic patients showed higher COXq/CSa ratio than nonsurviving individuals, that patients from the JT mtDNA haplogroup showed a higher COXq/CSa ratio and that JT patients had a higher 1-month survival than patients from other mtDNA haplogroups.

    Purpose: The Intergroup 0116 (INT 0116) trial demonstrated a survival benefit for a broad group of fully resected gastric cancer patients. This study examined the impact on survival of the release of this landmark trial. Methods and Materials: Patients with gastric carcinoma diagnosed between 1995 and 2004 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Patients from the overall population as well as those potentially eligible for the INT 0116 trial were classified as having been diagnosed either before (1995-1999) or after (2000-2004) this trial. Both Kaplan-Meier survival analysis and Cox models were used to examine survival trends within these cohorts. Results: For the overall population of 22,982 patients, the use of radiotherapy (RT) significantly changed after the INT 0116 trial (p < 0.0001), with postoperative RT increasing from 6.5% to 13.3%. For the two periods of interest, overall survival significantly improved in recent years (p = 0.00008). A similar improvement was also seen for patients who were potentially eligible for the INT 0116 trial (p = 0.004), with 3-year survival rates improving from 32.2% to 34.5%. On both univariate and multivariate analysis, use of RT was associated with a significant survival improvement (HR, 0.65 [0.48-0.88]; p = 0.005). Conclusion: Use of postoperative RT for gastric cancer has significantly increased after the release of the INT 0116 trial, likely reflecting increased use of adjuvant chemoradiotherapy. This change has been associated with improved survival in gastric cancer patients, suggesting that the improved outcome seen in this trial has been successfully translated to the community.

    The causes of graft loss were analysed in a group of 487 kidney transplants, of which 252 (51.46%) concerned related donors, 139 (28.5%) cadaver donors and 96 (19.7%) non-related donors. A total of 74 kidneys were lost in the first 3 months after transplantation (15.19%). In 34 cases the loss was due to immunological factors (45.9%) in 21 cases (28.3%) to the death of the patients and in 19 cases (25.7%) to the technical causes. From 34 losses by immunological problems, 32 were rejections with humoral character (acute vascular rejection in 11 cases, late humoral rejection in 11 cases, immediate humoral rejection in 9 cases, ABO incompatibility in one case) and recurrence of original disease in one case. Acute cellular rejection was observed in only one patient. None of the patients died from immunological loss of the graft. The most frequent cause of death were sepsis (13 out of 21 patients) and the most common focus of infection was pulmonary (5 patients). It occurred most frequently with cadaveric donor, (10.07%). Death related to cardiovascular causes occurred in four patients, digestive in two and in consequence of arterial bleeding in two. Among the 23 losses by technical factors renal artery thrombosis was the most frequent (11 cases); renal rupture occurred in three cases, renal vein thrombosis in two rupture of arterial anastomosis in one and inviable kidney in another one. The technical loss was most frequent with cadaver donors (8.63%), followed by non-related donors (4.16%) and related donors (2.77%). Four patients died from causes directly related to technical factors.(ABSTRACT TRUNCATED AT 250 WORDS)

    Aim of this retrospective analysis was to evaluate the survival times after percutaneous irreversible electroporation (IRE) in inoperable liver tumors not amenable to thermal ablation. 71 patients (14 females, 57 males, median age 63.5 ± 10.8 years) with 103 liver tumors were treated in 83 interventions using IRE (NanoKnife® system). The median tumor short-axis diameter was 1.9 cm (minimum 0.4 cm, maximum 4.5 cm). 35 patients had primary liver tumors and 36 patients had liver metastases. The Kaplan-Meier method was employed to calculate the survival rates, and the different groups were compared using multivariate log-rank and Wilcoxon tests. The overall median survival time was 26.3 months; the median survival of patients with primary land secondary liver cancer did not significantly differ (26.8 vs. 19.9 months; p = 0.41). Patients with a tumor diameter >3 cm (p < 0.001) or more than 2 lesions (p < 0.005) died significantly earlier than patients with smaller or fewer tumors. Patients with hepatocellular carcinoma and Child-Pugh class B or C cirrhosis died significantly earlier than patients with Child-Pugh class A (p < 0.05). Patients with very early stage HCC survived significantly longer than patients with early stage HCC with a median survival of 22.3 vs. 13.7 months (p < 0.05). PMID:28266600

    The International Germ Cell Consensus (IGCC) classification identifies good, intermediate and poor prognosis groups among patients with metastatic nonseminomatous germ cell tumours (NSGCT). It uses the risk factors primary site, presence of nonpulmonary visceral metastases and tumour markers alpha-fetoprotein (AFP), human chorionic gonadotrophin (HCG) and lactic dehydrogenase (LDH). The IGCC classification is easy to use and remember, but lacks flexibility. We aimed to examine the extent of any loss in discrimination within the IGCC classification in comparison with alternative modelling by formal weighing of the risk factors. We analysed survival of 3048 NSGCT patients with Cox regression and recursive partitioning for alternative classifications. Good, intermediate and poor prognosis groups were based on predicted 5-year survival. Classifications were further refined by subgrouping within the poor prognosis group. Performance was measured primarily by a bootstrap corrected c-statistic to indicate discriminative ability for future patients. The weights of the risk factors in the alternative classifications differed slightly from the implicit weights in the IGCC classification. Discriminative ability, however, did not increase clearly (IGCC classification, c=0.732; Cox classification, c=0.730; Recursive partitioning classification, c=0.709). Three subgroups could be identified within the poor prognosis groups, resulting in classifications with five prognostic groups and slightly better discriminative ability (c=0.740). In conclusion, the IGCC classification in three prognostic groups is largely supported by Cox regression and recursive partitioning. Cox regression was the most promising tool to define a more refined classification.

    Purpose: Evaluate efficacy and toxicity of salvage high-dose-rate brachytherapy (HDRB) for locally recurrent prostate cancer after definitive radiation therapy (RT). Methods and Materials: We retrospectively analyzed 52 consecutively accrued patients undergoing salvage HDRB between 1998 and 2009 for locally recurrent prostate cancer after previous definitive RT. After pathologic confirmation of locally recurrent disease, patients received 36 Gy in 6 fractions. Twenty-four patients received neoadjuvant hormonal therapy before salvage, and no patients received adjuvant hormonal therapy. Determination of biochemical failure after salvage HDRB was based on the Phoenix definition. Overall survival (OS) and bF distributions were calculated using the Kaplan-Meier method. Univariate analyses were performed to identify predictors of biochemical control. Acute and late genitourinary (GU) and gastrointestinal (GI) toxicities, based on Common Terminology Criteria for Adverse Events (version 4), were documented. Results: Median follow-up after salvage HDRB was 59.6 months. The 5-year OS estimate was 92% (95% confidence interval [CI]: 80%-97%) with median survival not yet reached. Five-year biochemical control after salvage was 51% (95% CI: 34%-66%). Median PSA nadir postsalvage was 0.1 (range: 0-7.2) reached at a median of 10.2 months after completing HDRB. As for complications, acute and late grade 3 GU toxicities were observed in only 2% and 2%, respectively. No grade 2 or higher acute GI events and 4% grade 2 GI late events were observed. On univariate analysis, disease-free interval after initial definitive RT (P=.07), percent of positive cores at the time of diagnosis (P=.08), interval from first recurrence to salvage HDRB (P=.09), and pre-HDRB prostate-specific antigen (P=.07) were each of borderline significance in predicting biochemical control after salvage HDRB. Conclusions: Prostate HDRB is an effective salvage modality with relatively few long-term toxicities. We

    In northeast Thailand, cholangiocarcinoma (CCA) is a major cause of mortality. Patients with CCA have a poor prognosis and short-term survival. The purpose of this study was to investigate the association between health-related quality of life (HRQOL) and survival time, and to explore whether change in HRQOL score is related to survival among CCA patients. The study was performed between February 2011 and January 2012, and included 171 patients with newly diagnosed CCA from 5 tertiary hospitals in four provinces of northeast Thailand. The HRQOL was measured at baseline, 1 month, and 2 months after diagnosis by the FACT-Hep questionnaire (Thai version 4). The outcome was survival time from diagnosis. Cox’s proportional hazard model was used to evaluate the association between HRQOL and survival time. A higher overall score on HRQOL was associated with a significantly better survival (HR per 5 units increase in HRQOL was 0.92, 95% CI: 0.88–0.96). Two of the separate domains contributing to the overall HRQOL—functional well-being and hepatobiliary cancer subscale—were found to have independent effects on survival, even after adjustment for potential confounding variables, and the other domains of HRQOL. CCA patient whose HRQOL scores had improved (≥9 units) at the 1st month of follow up had a reduced probability of dying from the disease (HR: 0.56, 0.32–0.95) after adjustment for the same confounding factors. A positive association between HRQOL at diagnosis and survival time was found. An improvement in HRQOL score in the first months after diagnosis further increases survival. PMID:27685448

    OBJECTIVE An increased extent of resection (EOR) has been shown to improve overall survival of patients with glioblastoma (GBM) but has the potential for causing a new postoperative neurological deficit. To investigate the impact of surgical neurological morbidity on survival, the authors performed a retrospective analysis of the clinical data from patients with GBM to quantify the impact of a new neurological deficit on the survival benefit achieved with an increased EOR. METHODS The data from all GBM patients who underwent resection at the University of Florida from 2010 to 2015 with postoperative imaging within 72 hours of surgery were included in the study. Retrospective analysis was performed on clinical outcomes and tumor volumes determined on postoperative and follow-up imaging examinations. RESULTS Overall, 115 patients met the inclusion criteria for the study. Tumor volume at the time of presentation was a median of 59 cm(3) (enhanced on T1-weighted MRI scans). The mean EOR (± SD) was 94.2% ± 8.7% (range 59.9%-100%). Almost 30% of patients had a new postoperative neurological deficit, including motor weakness, sensory deficits, language difficulty, visual deficits, confusion, and ataxia. The neurological deficits had resolved in 41% of these patients on subsequent follow-up examinations. The median overall survival was 13.1 months (95% CI 10.9-15.2 months). Using a multipredictor Cox model, the authors observed that increased EOR was associated with improved survival except for patients with smaller tumor volumes (≤ 15 cm(3)). A residual volume of 2.5 cm(3) or less predicted a favorable overall survival. Developing a postoperative neurological deficit significantly affected survival (9.2 months compared with 14.7 months, p = 0.02), even if the neurological deficit had resolved by the first follow-up. However, there was a trend of improved survival among patients with resolution of a neurological deficit by the first follow-up compared with patients

    Abstract Background: Brachytherapy with iodine125-labeled seeds (125I-seeds) implantation is increasingly being used to treat tumors because of its positional precision, minimal invasion, least damage to noncancerous tissue due to slow and continuous release of radioactivity and facilitation with modern medical imaging technologies. This study evaluates the survival and pain relief outcomes of the 125I-seeds implantation brachytherapy in advanced pancreatic cancer patients. Methods: Literature search was carried out in multiple electronic databases (Google Scholar, Embase, Medline/PubMed, and Ovid SP) and studies reporting I125 seeds implantation brachytherapy in pancreatic cancer patients with unresectable tumor were selected by following predetermined eligibility criteria. Random effects meta-analysis was performed to achieve inverse variance weighted effect size of the overall survival rate after the intervention. Sensitivity and subgroups analyses were also carried out. Results: Twenty-three studies (824 patients’ data) were included in the meta-analysis. 125I-seeds implantation brachytherapy alone was associated with 8.98 [95% confidence interval (CI): 6.94, 11.03] months (P < 0.00001) overall survival with 1-year survival of 25.7 ± 9.3% (mean ± standard deviation; SD) and 2-year survival was 17.9 ± 8.6% (mean ± SD). In stage IV pancreatic cancer patients, overall survival was 7.13 [95% CI: 4.75, 9.51] months (P < 0.00001). In patients treated with 125I-seeds implantation along with 1 or more therapies, overall survival was 11.75 [95% CI: 9.84, 13.65] months (P < 0.00001) with 1-year survival of 47.4 ± 22.75% (mean ± SD) and 2-year survival was 16.97 ± 3.1% (mean ± SD). 125I-seeds brachytherapy was associated with relief of pain in 79.7 ± 9.9% (mean ± SD) of the patients. Conclusions: Survival of pancreatic cancer patients after 125I-seeds implantation brachytherapy is found to be 9 months

    This study investigated the existence of racial differences in the survival of patients admitted to intensive care by family physicians and general internists for circulatory illnesses. The study population consisted of 249 consecutive patients admitted by these specialists to an ICU in a tertiary care hospital in Pitt County, North Carolina, during the June 1985 to June 1986 period. Logistic regression was used to specify the unique effect of race on ICU patient survival in-hospital, controlling for potential confounding factors such as disease severity, type of health insurance, and case mix. Black patients were almost three times more likely than white patients to die in-hospital following admission to the ICU (RR = 2.9, 95 percent I = 1.5, 5.6). Most of this difference in survival was explained by racial differences in disease severity. PMID:1917504

    Survival of bladder cancer patients depends on several factors including disease stage and grade at diagnosis, age, health status of the patient and the applied treatment. Several studies investigated the role of DNA repair genetic variants in cancer susceptibility, but only few studies investigated their role in survival and response to chemotherapy for bladder cancer. We genotyped 28 single nucleotide polymorphisms (SNP) in DNA repair genes in 456 bladder cancer patients, reconstructed haplotypes and calculated a score for combinations of the SNPs. We estimated Hazard Ratios (adjHR) for time to death. Among patients treated with chemotherapy, variant alleles of five SNPs in the XRCC1 gene conferred better survival (rs915927 adjHR 0.55 (95%CI 0.32-0.94); rs76507 adjHR 0.48 (95%CI 0.27-0.84); rs2854501 adjHR 0.25 (95%CI 0.12-0.52); rs2854509 adjHR 0.21 (95%CI 0.09-0.46); rs3213255 adjHR 0.46 (95%CI 0.26-0.80). In this group of patients, an increasing number of variant alleles in a XRCC1 gene score were associated with a better survival (26% decrease of risk of death for each additional variant allele in XRCC1). By functional analyses we demonstrated that the previous XRCC1 SNPs confer lower DNA repair capacity. This may support the hypothesis that survival in these patients may be modulated by the different DNA repair capacity determined by genetic variants. Chemotherapy treated cancer patients bearing an increasing number of "risky" alleles in XRCC1 gene had a better survival, suggesting that a proficient DNA repair may result in resistance to therapy and shorter survival. This finding may have clinical implications for the choice of therapy.

    A literature review was conducted to investigate the influence of patient-related factors on restoration survival in posterior permanent teeth as well as to report the methods used to collect these factors. The selection of articles on longitudinal clinical studies investigating the survival of posterior restorations (except full crowns and temporary fillings) and including patient-related factors was performed by applying predefined criteria. The review was organized into two parts, the first describing how patient factors were assessed in the studies (n=45) and the second presenting the statistical significance (n=27) and size of the effect (n=11) of these factors on restoration survival. Patient-related factors mentioned in the studies included age; gender; caries risk; caries activity/severity; decayed, missing, filled teeth; number of restorations; oral hygiene; and bruxism, among others. Sixteen studies included the patient age or age range in the analysis, which was found to be significant in 47% of the studies. Regarding gender, four of 17 reports found a significant effect on survival, showing more failures for men in three studies. The caries risk profile or related variables were included in the analysis of 15 studies, and a significant effect on survival was reported for high-caries-risk individuals (or related variables) in 67% of these studies. Bruxism was also found to influence restoration survival in three of six studies where this variable was investigated. Some issues were found regarding the reporting of methods used to classify patients according to risk and were thoroughly discussed. In view of the information gathered in this review, the assessment of patient factors along with other variables should become part of clinical studies investigating restoration survival, since several of these factors were shown to influence the failure of restorations, regardless of the material type.

    Variceal hemorrhage is a major cause of death in patients with cirrhosis. Over the past two decades new treatment modalities have been introduced in the management of acute variceal bleeding (AVB) and several recent studies have suggested that the outcome of patients with cirrhosis and AVB has improved. Improved supportive measures, combination therapy which include early use of portal pressure reducing drugs with low rates of adverse effects (somatostatin, octerotide or terlipressin) and endoscopic variceal ligation has become the first line treatment in the management of AVB. Short-term antibiotic prophylaxis, early use of lactulose for prevention of hepatic encephalopathy, application of early transjugular intrahepatic portasystemic shunts (TIPS), fully covered self-expandable metallic stent in patients for AVB may be useful in those cases where balloon tamponade is considered. Early and wide availability of liver transplantation has changed the armamentarium of the clinician for patients with AVB. High hepatic venous pressure gradient (HVPG) >20 mmHg in AVB has become a useful predictor of outcomes and more aggressive therapies with early TIPS based on HVPG measurement may be the treatment of choice to reduce mortality further.

Improved supportive measures, combination therapy which include early use of portal pressure reducing drugs with low rates of adverse effects (somatostatin, octerotide or terlipressin) and endoscopic variceal ligation has become the first line treatment in the management of AVB. Short-term antibiotic prophylaxis, early use of lactulose for prevention of hepatic encephalopathy, application of early transjugular intrahepatic portasystemic shunts (TIPS), fully covered self-expandable metallic stent in patients for AVB may be useful in those cases where balloon tamponade is considered. Early and wide availability of liver transplantation has changed the armamentarium of the clinician for patients with AVB. High hepatic venous pressure gradient (HVPG) >20 mmHg in AVB has become a useful predictor of outcomes and more aggressive therapies with early TIPS based on HVPG measurement may be the treatment of choice to reduce mortality further.

    The aim of this study was to determine trends in incidence, treatment and survival of colorectal cancer (CRC) patients with synchronous metastases (Stage IV) in the Netherlands. This nationwide population-based study included 160,278 patients diagnosed with CRC between 1996 and 2011. We evaluated changes in stage distribution, location of synchronous metastases and treatment in four consecutive periods, using Chi square tests for trend. Median survival in months was determined, using Kaplan-Meier analysis. The proportion of Stage IV CRC patients (n = 33,421) increased from 19 % (1996-1999) to 23 % (2008-2011, p < 0.001). This was predominantly due to a major increase in the incidence of lung metastases (1.7-5.0 % of all CRC patients). During the study period, the primary tumor was resected less often in Stage IV patients (65-46 %) and the use of systemic treatment has increased (29-60 %). Also an increase in metastasectomy was found in patients with one metastatic site, especially in patients with liver-only disease (5-18 %, p < 0.001). Median survival of all Stage IV CRC patients increased from 7 to 12 months. Especially in patients with metastases confined to the liver or lungs this improvement in survival was apparent (9-16 and 12-24 months respectively, both p < 0.001). In the last two decades, more lung metastases were detected and an increasing proportion of Stage IV CRC patients was treated with systemic therapy and/or metastasectomy. Survival of patients has significantly improved. However, the prognosis of Stage IV patients becomes increasingly diverse.

    In patients with thalassemia intermedia (TI), such as beta-TI, alpha-thalassemia (mainly HbH disease and mild/moderate forms of HbE/beta-thalassemia), iron overload is an important challenge in terms of diagnosis, monitoring, and treatment. Moreover, to date, the only possible chelators available are deferoxamine, deferasirox, and deferiprone. Here, we report the first 5-year long-term randomized clinical trial comparing the effectiveness of deferiprone versus deferoxamine in patients with TI. Body iron burden, which was determined by measuring serum ferritin levels in the same patient over 5 years and analyzed according to the generalized linear mixed model (GLMM), showed a linear decrease over time in the mean serum ferritin levels in both treatment groups (P-value = 0.035). The overall period of observation was 235.2 person-years for the deferiprone patients compared with 214.3 person-years for the deferoxamine patients. The results of the log-rank test suggested that the deferiprone treatment did not affect survival compared with the deferoxamine treatment (P-value = 0.360). The major adverse events observed included gastrointestinal symptoms and joint pain or arthralgia. Neutropenia and agranulocytosis were also detected, suggesting needing of strict hematological control. In conclusion, long-term iron chelation therapy with deferiprone is associated with an efficacy and safety similar to that of deferoxamine, suggesting that this drug is an alternative option in cases in which deferoxamine and deferasirox are contraindicated.

    AIM: To explore if vascular endothelial growth factor receptor-3 (VEGFR-3) and carcinoembryonic antigen (CEA) can predict overall survival in advanced gastric cancer. METHODS: VEGFR-3 level was assessed by enzyme-linked immunosorbent assay, and CEA was assessed by chemiluminescence immunoassay in the sera of 81 advanced gastric cancer patients before treatment with oxaliplatin plus 5-fluorouracil and folinic acid. RESULTS: Median survival time in patients with a low serum VEGFR-3 level was significantly longer than in those with a higher VEGFR-3 level (15.4 mo vs 7.7 mo, P < 0.001). Patients with a low CEA level had a longer survival than those with a higher CEA level (15.8 mo vs 8.6 mo, P < 0.001). Thirty-nine patients with low VEGFR-3 and low CEA levels had a median survival of 19.7 mo (P = 0.0006). The hazard ratio for patients with a high VEGFR-3 level was 2.443 (P = 0.002). CONCLUSION: High serum VEGFR-3 level is correlated significantly with poor survival. In patients with a high serum level of VEGFR-3, alternative chemotherapy regimens should be considered.

    The optimal schedule for ultrasonographic surveillance of patients with viral hepatitis for the detection of hepatocellular carcinoma (HCC) remains unclear owing to a lack of reliable studies. We examined the timing of ultrasonography in patients with viral hepatitis-induced HCC and its impact on survival and mortality risk while determining predictors of receiving surveillance before HCC diagnosis. A population-based retrospective cohort analysis of patients with viral hepatitis-induced HCC in Ontario between 2000 and 2010 was performed using data from the Ontario Cancer Registry linked health administrative data. HCC surveillance for 2 years preceding diagnosis was assigned as: i) ≥ 2 abdominal ultrasound screens annually; ii) 1 screen annually; iii) inconsistent screening; and iv) no screening. Survival rates were estimated using the Kaplan-Meier method and parametric models to correct for lead-time bias. Associations between HCC surveillance and the risk of mortality after diagnosis were examined using proportional-hazards regression adjusting for confounding factors. Overall, 1,483 patients with viral hepatitis-induced HCC were identified during the study period; 20.2% received ≥ 1 ultrasound screen annually (routine surveillance) for the 2 years preceding diagnosis. The 5-year survival of those receiving routine surveillance was 31.93% (95% CI: 25.77-38.24%) and 31.84% (95% CI: 25.69-38.14%) when corrected for lead-time bias (HCC sojourn time 70 days and 140 days, respectively). This is contrasted with 20.67% (95% CI: 16.86-24.74%) 5-year survival in those who did not undergo screening. In the fully adjusted model, compared to unscreened patients, routine surveillance was associated with a lower mortality risk and a hazard ratio of 0.76 (95% CI: 0.64-0.91) and 0.81 (95% CI: 0.68-0.97), corrected for the respective lead-time bias. Our findings suggest that routine ultrasonography in patients with viral hepatitis is associated with improved survival and

    Purpose. To analyze the factors associated with favorable survival in patients with inoperable colorectal lung metastases treated with percutaneous image-guided radiofrequency ablation. Methods. Between 2002 and 2011, a total of 398 metastases were ablated in 122 patients (87 male, median age 68 years, range 29-90 years) at 256 procedures. Percutaneous CT-guided cool-tip radiofrequency ablation was performed under sedation/general anesthesia. Maximum tumor size, number of tumors ablated, number of procedures, concurrent/prior liver ablation, previous liver or lung resection, systemic chemotherapy, disease-free interval from primary resection to lung metastasis, and survival from first ablation were recorded prospectively. Kaplan-Meier analysis was performed, and factors were compared by log rank test. Results. The initial number of metastases ablated was 2.3 (range 1-8); the total number was 3.3 (range 1-15). The maximum tumor diameter was 1.7 (range 0.5-4) cm, and the number of procedures was 2 (range 1-10). The major complication rate was 3.9 %. Overall median and 3-year survival rate were 41 months and 57 %. Survival was better in patients with smaller tumors-a median of 51 months, with 3-year survival of 64 % for tumors 2 cm or smaller versus 31 months and 44 % for tumors 2.1-4 cm (p = 0.08). The number of metastases ablated and whether the tumors were unilateral or bilateral did not affect survival. The presence of treated liver metastases, systemic chemotherapy, or prior lung resection did not affect survival. Conclusion. Three-year survival of 57 % in patients with inoperable colorectal lung metastases is better than would be expected with chemotherapy alone. Patients with inoperable but small-volume colorectal lung metastases should be referred for ablation.

    Background The bevacizumab and irinotecan protocol is considered a standard treatment regimen for recurrent malignant glioma. Recent advances in immunotherapy have hinted that vaccination with dendritic cells could become an alternative salvage therapy for the treatment of recurrent malignant glioma. Methods A search was performed on PubMed, Cochrane Library, Web of Science, ScienceDirect, and Embase in order to identify studies with patients receiving bevacizumab plus irinotecan or dendritic cell therapy for recurrent malignant gliomas. The data obtained from these studies were used to perform a systematic review and survival gain analysis. Results Fourteen clinical studies with patients receiving either bevacizumab plus irinotecan or dendritic cell vaccination were identified. Seven studies followed patients that received bevacizumab plus irinotecan (302 patients) and seven studies included patients that received dendritic cell immunotherapy (80 patients). For the patients who received bevacizumab plus irinotecan, the mean reported median overall survival was 7.5 (95% confidence interval [CI] 4.84–10.16) months. For the patients who received dendritic cell immunotherapy, the mean reported median overall survival was 17.9 (95% CI 11.34–24.46) months. For irinotecan + bevacizumab group, the mean survival gain was −0.02±2.00, while that for the dendritic cell immunotherapy group was −0.01±4.54. Conclusion For patients with recurrent malignant gliomas, dendritic cell immunotherapy treatment does not have a significantly different effect when compared with bevacizumab and irinotecan in terms of survival gain (P=0.535) and does not improve weighted survival gain (P=0.620).

    The number of lymph nodes removed is one of the important predictors for survival in breast cancer study. Our aim is to determine the optimal number of lymph nodes to be removed for maximizing the survival of breast cancer patients. The study population consists of 873 patients with at least one of axillary nodes involved among 1890 patients from the University of Malaya Medical Center (UMMC) breast cancer registry. For this study, the Chi-square test of independence is performed to determine the significant association between prognostic factors and survival status, while Wilcoxon test is used to compare the estimates of the hazard functions of the two or more groups at each observed event time. Logistic regression analysis is then conducted to identify important predictors of survival. In particular, Akaike's Information Criterion (AIC) are calculated from the logistic regression model for all thresholds of node involved, as an alternative measure for the Wald statistic (χ2), in order to determine the optimal number of nodes that need to be removed to obtain the maximum differential in survival. The results from both measurements are compared. It is recommended that, for this particular group, the minimum of 10 nodes should be removed to maximize survival of breast cancer patients.

    Background: A phase III trial demonstrated an overall survival advantage with the addition of vinflunine to best supportive care (BSC) in platinum-refractory advanced urothelial cancer. We subsequently examined the impact of an additional 2 years of survival follow-up and evaluated the influence of first-line platinum therapy on survival. Methods: The 357 eligible patients from the phase III study were categorised into two cohorts depending on prior cisplatin treatment: cisplatin or non-cisplatin. Survival was calculated using the Kaplan–Meier method. Results: The majority had received prior cisplatin (70.3%). Survival was higher in the cisplatin group (HR: 0.76; CI 95% 0.58–0.99; P=0.04) irrespective of treatment arm. Multivariate analysis including known prognostic factors (liver involvement, haemoglobin, performance status) and prior platinum administration did not show an independent effect of cisplatin. Vinflunine reduced the risk of death by 24% in the cisplatin-group (HR: 0.76; CI 95% 0.58–0.99; P=0.04) and by 35% in non-cisplatin patients (HR: 0.65; CI 95% 0.41–1.04; P=0.07). Interpretation: Differences in prognostic factors between patients who can receive prior cisplatin and those who cannot may explain the survival differences in patients who undergo second line therapy. Prior cisplatin administration did not diminish the subsequent benefit of vinflunine over BSC. PMID:24129239

    Purpose: The outcome of a prospective case series of 47 patients with newly diagnosed resectable locoregionally advanced oropharyngeal squamous cell carcinoma treated with platinum-based induction-concurrent chemoradiotherapy (IC/CCRT) was compared with the outcome of 47 matched historical control patients treated with surgery and postoperative RT. Methods and Materials: A total of 47 control patients with locoregionally advanced oropharyngeal squamous cell carcinoma were identified from review of a prospectively compiled comprehensive computerized head-and-neck cancer database and were matched with a prospective case series of patients undergoing IC/CCRT by disease stage, nodal status, gender, and age ({+-}5 years). The IC/CCRT regimen consisted of one cycle of induction chemotherapy followed by conventionally fractionated RT to a total dose of 66-70 Gy concomitantly with two cycles of chemotherapy. Each cycle of chemotherapy consisted of cisplatinum, 100 mg/m{sup 2}, and a continuous infusion of 5-fluorouracil, 1,000 mg/m{sup 2}/d for 5 days. The survival analysis was performed using Kaplan-Meier estimates. Matched-pair survival was compared using the Cox proportional hazards model. Results: No significant difference was found in the overall survival or progression-free survival rates between the two groups. The matched analysis of survival did not show a statistically significant greater hazard ratio for overall death (hazard ratio, 1.35; 95% confidence interval, 0.65-2.80; p = .415) or progression (hazard ratio, 1.44; 95% confidence interval, 0.72-2.87; p = .301) for patients undergoing IC/CCRT. Conclusion: Although the sample size was small and not randomized, this matched-pair comparison between a prospective case series and a historical cohort treated at the same institution showed that the efficacy of IC/CCRT with salvage surgery is as good as primary surgical resection and postoperative RT.

    We present a case of pyomyositis in an otherwise healthy 5-year-old child that underscores the potential for serious, life-threatening complications. Pyomyositis of the gluteal, psoas, and iliacus muscles was associated with osteomyelitis, septic arthritis, a large inferior vena cava thrombus, septic pulmonary emboli, and eventual pneumonia. Primary pyomyositis is a purulent infection of striated muscle thought to be caused by seeding from a transient bacteremia. The focal infection typically forms an abscess that generally responds to intravenous antibiotics and occasionally requires adjunctive computed tomography-guided aspiration and drainage. This localized infectious process rarely produces further sequelae unless treatment is delayed. Pyomyositis is rare in healthy individuals and requires a high clinical suspicion in patients who present with fever, leukocytosis, and localized pain.

    Diffuse malignant pleural mesothelioma (MPM) is an aggressive tumor that originates from the surface of the pleura. Approximately 70% of cases are associated with chronic asbestos exposure. MPM is regarded as an incurable disease, with a median survival of ~2 years following intensive multimodality treatment. Pancreatic cancer is a malignancy also associated with a poor prognosis, with only 2% of patients surviving for 5 years. The majority of patients with pancreatic cancer are diagnosed with an advanced stage of disease and experience a poor response to therapy. The development of synchronous MPM and other types of cancer is rare. The present study describes a patient with synchronous, biphasic MPM and pancreatic adenocarcinoma, who was treated with a multimodal therapeutic approach with stereotactic body radiation therapy. Due to a suspected diagnosis of ‘acute abdomen’, an emergency small intestine resection was performed and a subsequent diagnosis of moderately-differentiated adenocarcinoma was confirmed. During a further immunohistochemical examination, pathologists determined that the small bowel metastasis descended from pancreatic cancer. The onset of bowel metastasis is an event rarely associated with MPM, and has not been previously described in the literature for cases of pancreatic cancer. Therefore, to the best of our knowledge, the present study describes the first case of intestinal metastasis from pancreatic cancer in a long-term survival patient with biphasic MPM. PMID:28105159

    BACKGROUND: Few studies have prospectively reported outcomes in patients with pulmonary arterial hypertension (PAH) treated with epoprostenol in the modern-day era of oral therapy and combination treatments. The Registry to Prospectively Describe Use of Epoprostenol for Injection (Veletri, prolonged room temperature stable-epoprostenol [RTS-Epo]) in Patients with Pulmonary Arterial Hypertension (PROSPECT) was established to prospectively describe the course of PAH in patients prescribed RTS-Epo. METHODS: PROSPECT is a multicenter, US-based drug registry of primarily group 1 patients with PAH treated with RTS-Epo who were parenteral-naive or parenteral-transitioned at enrollment. Patients were followed until discontinuation of RTS-Epo, withdrawal, loss to follow-up, death, or end of study (maximum 1 year). One-year freedom from hospitalization (FH) and survival estimates were summarized by prostacyclin history (parenteral-naive or parenteral-transitioned), sex, and chronic renal insufficiency (CRI). RESULTS: A total of 336 patients were included. The overall 1-year FH estimate was 51.0% ± 2.8% and was lower in parenteral-naive patients than parenteral-transitioned patients (42.8% ± 4.3% vs 57.1% ± 3.7%, respectively; P = .002). FH estimates were lower in male patients than female patients (38.3% ± 5.9% vs 54.6% ± 3.2%, respectively; P < .015) and in patients with CRI than patients without CRI (17.0% ± 8.4% vs 53.7% ± 2.9%, respectively; P < .001). The overall 1-year survival estimate was 84.0% ± 2.1%. Survival was poorer in parenteral-naive patients, male patients, and patients with CRI. CONCLUSIONS: Risk of hospitalization and mortality remain high in patients with PAH. In particular, patients who are parenteral-naive at initiation of RTS-Epo therapy, male patients, and patients with CRI require close monitoring and aggressive clinical management. PMID:25320967

    ABSTRACT Colorectal cancer is third leading cause of cancer mortality. About 60% of patients had already developed metastasis at the time of diagnosis. Vascular endothelial growth factor (VEGF) is crucial for the development of neovascularization and hence metastasis. This study aimed at investigating the relation between the expression of VEGF in biopsies from surgically dissected colon cancer and the survival of those patients. Biopsies were collected from 86 patients with advanced colon cancer and sections were stained by immunohistochemistry for VEGF. Patients received chemotherapy after the operation and were followed up for disease progression and survival. The clinical data were statistically analyzed with respect to the immunohistochemistry results. The survival of the patients was significantly longer in the patients for whom biopsies showed negative or weak expression of VEGF in comparison to those with moderate to high expression (p-value = 0.04). The expression of VEGF was more frequent in the patients who died as a consequence of the disease in comparison to the 10-year survivors. In conclusion, VEGF could be related to the survival of the patients with colorectal carcinoma and should be considered as a predictor of the prognosis. PMID:28245709

    Key Clinical Message The survival of multiple myeloma patients has improved very significantly over the last decade. Still median overall survival is inferior to 5 years. A small proportion of patients survive longer than 10 years. In this paper we discuss four cases illustrating the nonhomogeneous clinical presentation and evolution of this subset of patients. Surprisingly, these long survivors do not always have deep responses and some require frequent treatments, which include autologous stem cell transplantation and novel drugs. The authors discuss several aspects of these clinical histories, including treatment options, raising hypothesis on their relation with long survivorship which may be important to have in consideration when studying this subject.

    Background Little is known regarding racial disparities in characteristics and outcomes among patients with chronic lymphocytic leukemia (CLL). Methods The characteristics and outcomes of untreated African American (AA) patients with CLL (n=84) were analyzed and compared with a reference nonblack (NB) patient population (n=1571). Results At the time of presentation, AA patients had lower median hemoglobin levels (12.9 g/dL vs 13.7 g/dL), higher β2 microglobulin levels (2.7 mg/dL vs 2.4 mg/dL), greater frequency of constitutional symptoms (27% vs 10%), unmutated immunoglobulin heavy-chain variable region (IGHV) mutation status (65% vs 47%), ζ-chain-associated protein kinase 70 (ZAP70) expression (58% vs 32%), and deletion of chromosome 17p or chromosome 11q (28% vs 17%; P ≤ 02 for each comparison). Fifty-one percent of AA patients and 39% of NB patients required first-line therapy and 91% and 88%, respectively, received chemoimmunotherapy. Overall response rates to treatment were 85% for AA patients and 94% for NB patients (P=.06); and the complete response rates were 56% and 58%, respectively (P=.87). The median survival of AA patients was shorter compared with that of NB patients (event-free survival: 36 months vs 61 months; P=.007; overall survival: 152 months vs not reached; P=.0001). AA race was an independent predictor of shorter event-free and overall survival in multivariable regression models. Conclusions The current results indicated that AA patients with CLL have more unfavorable prognostic characteristics and shorter survival compared with their NB counterparts. PMID:24022787

    Factors known to affect melanoma survival include age at presentation, sex and tumor characteristics. Polymorphisms also appear to modulate survival following diagnosis. Result from other studies suggest that vitamin D receptor (VDR) polymorphisms (SNPs) impact survival in patients with glioma, renal cell carcinoma, lung, breast, prostate and other cancers; however, a comprehensive study of VDR polymorphisms and melanoma-specific survival is lacking. We aimed to investigate whether VDR genetic variation influences survival in patients with cutaneous melanoma. The analysis involved 3566 incident single and multiple primary melanoma cases enrolled in the international population-based Genes, Environment, and Melanoma Study. Melanoma-specific survival outcomes were calculated for each of 38 VDR SNPs using a competing risk analysis after adjustment for covariates. There were 254 (7.1%) deaths due to melanoma during the median 7.6 years follow-up period. VDR SNPs rs7299460, rs3782905, rs2239182, rs12370156, rs2238140, rs7305032, rs1544410 (BsmI) and rs731236 (TaqI) each had a statistically significant (trend P values < 0.05) association with melanoma-specific survival in multivariate analysis. One functional SNP (rs2239182) remained significant after adjustment for multiple testing using the Monte Carlo method. None of the SNPs associated with survival were significantly associated with Breslow thickness, ulceration or mitosis. These results suggest that the VDR gene may influence survival from melanoma, although the mechanism by which VDR exerts its effect does not seem driven by tumor aggressiveness. Further investigations are needed to confirm our results and to understand the relationship between VDR and survival in the combined context of tumor and host characteristics. PMID:26521212

These results suggest that the VDR gene may influence survival from melanoma, although the mechanism by which VDR exerts its effect does not seem driven by tumor aggressiveness. Further investigations are needed to confirm our results and to understand the relationship between VDR and survival in the combined context of tumor and host characteristics.

    Objective Thoracic radiotherapy (TRT) is a critical component of the treatment of limited-stage small cell lung cancer (LS-SCLC). However, the optimal radiation dose/fractionation remains elusive. This study reviewed current evidence and explored the dose-response relationship in patients with LS-SCLC who were treated with radiochemotherapy. Materials and Methods A quantitative analysis was performed through a systematic search of PubMed, Web of Science, and the Cochrane Library. The correlations between the biological effective dose (BED) and median overall survival (mOS), median progression-free survival (mPFS), 1-, 3-, and 5-year overall survival (OS) as well as local relapse (LR) were evaluated. Results In all, 2389 patients in 19 trials were included in this study. Among these 19 trials, seven were conducted in Europe, eight were conducted in Asia and four were conducted in the United States. The 19 trials that were included consisted of 29 arms with 24 concurrent and 5 sequential TRT arms. For all included studies, the results showed that a higher BED prolonged the mOS (R2 = 0.198, p<0.001) and the mPFS (R2 = 0.045, p<0.001). The results also showed that increased BED improved the 1-, 3-, and 5-year OS. A 10-Gy increment added a 6.3%, a 5.1% and a 3.7% benefit for the 1-, 3-, and 5-year OS, respectively. Additionally, BED was negatively correlated with LR (R2 = 0.09, p<0.001). A subgroup analysis of concurrent TRT showed that a high BED prolonged the mOS (p<0.001) and the mPFS (p<0.001), improved the 1-, 3-, and 5-year OS (p<0.001) and decreased the rate of LR (p<0.001). Conclusion This study showed that an increased BED was associated with improved OS, PFS and decreased LR in patients with LS-SCLC who were treated with combined chemoradiotherapy, which indicates that the strategy of radiation dose escalation over a limited time frame is worth exploring in a prospective clinical trial.

    Richter syndrome (RS) is associated with poor outcome. The prognosis of patients with histologically aggressive chronic lymphocytic leukemia (CLL), or HAC, has not been studied. We aimed to correlate 2-deoxy-2-[18F]fluoroglucose/positron emission tomography (FDG/PET) data, histological diagnosis, clinical characteristics, and survival in patients with CLL. A total of 332 patients with CLL were histologically classified as: 95 RS, 117 HAC, and 120 histologically indolent CLL (HIC). HAC and RS patients had higher maximum standardized uptake value (SUVmax), more frequent constitutional symptoms, poorer performance status (PS), lower hemoglobin and platelets, and higher lactate dehydrogenase and β-2-microglobulin. An SUVmax ≥10 strongly correlated with mortality (overall survival [OS], 56.7 vs 6.9 months in patients with SUVmax <10 vs ≥10). Survival of patients with RS and HAC was similar among patients with SUVmax <10 or ≥10. SUVmax ≥10, PS ≥2, bulky disease, and age ≥65 were independently associated with shorter OS. In patients undergoing both fine-needle aspiration and biopsy, the former proved diagnostically inadequate in 23%, 29%, and 53% of HIC, HAC, and RS, respectively. FDG/PET is a useful diagnostic tool in patients with CLL and suspected transformation. Patients with HAC show different characteristics and worse prognosis compared with those with HIC. Patients with different CLL phases, but similar SUVmax have similar outcome. Tissue biopsy should be preferred for diagnosing RS. PMID:24615780

    Morbidity and survival patterns were reviewed in 50 patients who underwent radical hysterectomy, pelvic lymphadenectomy, and adjuvant postoperative pelvic radiotherapy for invasive cervical cancer. Ninety percent of the patients were FIGO stage IB, and 10% were clinical stage IIA or IIB. Indications for adjuvant radiotherapy included pelvic lymph node metastasis, large volume, deep stromal penetration, lower uterine segment involvement, or capillary space involvement. Seventy-two percent of the patients had multiple high-risk factors. An average of 4700 cGy of whole-pelvis radiotherapy was administered. Ten percent of the patients suffered major gastrointestinal complications, 14% minor gastrointestinal morbidity, 12% minor genitourinary complications, one patient a lymphocyst, and one patient lymphedema. Of the five patients with major gastrointestinal morbidity, all occurred within 12 months of treatment. Three patients required intestinal bypass surgery for distal ileal obstructions and all are currently doing well and free of disease. All of the patients who developed recurrent disease had multiple, high-risk factors. The median time of recurrence was 12 months. All patients recurred within the radiated field. Actuarial survival was 90% and disease-free survival 87% at 70 months. It is our opinion that the morbidity of postoperative pelvic radiotherapy is acceptable, and benefit may be gained in such a high-risk patient population.

    Background While cardiovascular (CV) disease is a leading cause of morbidity and mortality in patients on chronic dialysis, utilization rates of cardioprotective drugs for dialysis patients remain low. This study sought to determine whether higher rates of cardioprotective drug use among dialysis patients might increase survival. Methods A retrospective cohort of incident dialysis patients (n = 50,468) with dual eligibility for U.S. Medicare and Medicaid was constructed using USRDS data linked with billing claims. Medication exposures included angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs), β-blockers, calcium channel blockers (CCBs), and HMG-CoA reductase inhibitors (statins) prescribed within 90 days of dialysis initiation. The outcomes were one- and two-year survival and CV event-free survival. Variation in treatment rates based on local area practice styles were used as instruments in instrumental variable (IV) estimation, yielding average treatment effect estimates for patients whose treatment choices were affected by local area practice styles. Results Patients aged 65 years and older comprised 47.4% of the sample, while 59.5% were female and 35.0% were white. The utilization rate was 40.7% for ACEIs/ARBs, 43.0% for β-blockers, 50.7% for CCBs and 26.4% for statins. The local area practice style instruments were highly significantly related to cardioprotective drug use in dialysis patients (Chow-F values > 10). IV estimates showed only that higher rates of β-blockers increased one-year survival (β = 0.161, P-value = 0.020) and CV event-free survival (β = 0.189, P-value = 0.033), but that higher rates of CCBs decreased two-year CV event-free survival (β = -0.520, P-value = 0.009). Conclusions This study suggests that higher utilization rates of β-blockers might yield higher survival rates for dialysis patients. However, higher rates of the other drugs studied had no correlations with survival, and higher CCB rates

    Purpose: To evaluate survival and neurocognitive outcomes in pediatric acute lymphoblastic leukemia (ALL) patients with central nervous system (CNS) involvement treated according to an institutional protocol with stem cell transplantation (SCT) and a component of craniospinal irradiation (CSI) in addition to total-body irradiation (TBI) as preparative regimen. Methods and Materials: Forty-one pediatric ALL patients underwent SCT with TBI and received additional cranial irradiation or CSI because of CNS leukemic involvement. Prospective neurocognitive testing was performed before and after SCT in a subset of patients. Cox regression models were used to determine associations of patient and disease characteristics and treatment methods with outcomes. Results: All patients received a cranial radiation boost; median total cranial dose was 24 Gy. Eighteen patients (44%) received a spinal boost; median total spinal dose for these patients was 18 Gy. Five-year disease-free survival (DFS) for all patients was 67%. Those receiving CSI had a trend toward superior DFS compared with those receiving a cranial boost alone (hazard ratio 3.23, P=.14). Patients with isolated CNS disease before SCT had a trend toward superior DFS (hazard ratio 3.64, P=.11, 5-year DFS 74%) compared with those with combined CNS and bone marrow disease (5-year DFS 59%). Neurocognitive testing revealed a mean post-SCT overall intelligence quotient of 103.7 at 4.4 years. Relative deficiencies in processing speed and/or working memory were noted in 6 of 16 tested patients (38%). Pre- and post-SCT neurocognitive testing revealed no significant change in intelligence quotient (mean increase +4.7 points). At a mean of 12.5 years after transplant, 11 of 13 long-term survivors (85%) had completed at least some coursework at a 2- or 4-year college. Conclusion: The addition of CSI to TBI before SCT in pediatric ALL with CNS involvement is effective and well-tolerated. Craniospinal irradiation plus TBI is worthy

    Abstract Human immunodeficiency virus (HIV)–positive cases have been reported among people who injected drugs in Liangshan Prefecture in southwest of China since 1995 and Liangshan has become one of the most seriously affected epidemic areas in China. In 2004, several patients with HIV/acquired immunodeficiency syndrome (AIDS) initiated antiretroviral treatment (ART) at the Central Hospital of Liangshan Prefecture. From 2005 to 2013, the number of patients receiving ART dramatically increased. We conducted a retrospective cohort study to analyze the long-term survival time and associated factors among patients with HIV/AIDS who received ART in Liangshan Prefecture for the first time. Data were collected from the Chinese AIDS Antiretroviral Therapy DATAFax Information System. A life table and the Kaplan–Meier and Cox proportion hazard regression were used to calculate the survival time and its associated factors, respectively. Among 8310 ART-naïve patients with HIV/AIDS who initiated ART, 436 patients died of AIDS-related diseases, and their median time of receiving ART was 15.0 ± 12.3 months, whereas 28.7% of them died within the first 6 months after treatment. The cumulative survival rates of those receiving ART in 1, 2, 3, 4, and 5 years were 97.1%, 93.4%, 90.6%, 88.8%, and 86.0%, respectively. Multivariate Cox regression analysis showed that male patients on ART were at a higher risk of death from AIDS-related diseases (adjusted hazard ratio [AHR] = 1.5, 95% confidence interval [CI]: 1.1–2.1) than female patients. Patients infected with HIV through injection drug use (IDU) were at a higher risk of death (AHR = 1.6, 95% CI: 1.2–2.2) than those infected through heterosexual transmission. Patients with a baseline CD4 cell count <50/mm3 (AHR = 9.8, 95% CI: 6.0–15.9), 50–199/mm3 (AHR = 3.3, 95% CI: 2.3–4.6), and 200–349/mm3 (AHR = 1.7, 95% CI: 1.2–2.3) were at a higher risk of death than those with a CD4 cell count ≥350/mm3.

    Cancer patients are subject to multiple competing risks of death and may die from causes other than the cancer diagnosed. The probability of not dying from the cancer diagnosed, which is one of the patients' main concerns, is sometimes called the 'personal cure' rate. Two approaches of modelling competing-risk survival data, namely the cause-specific hazards approach and the mixture model approach, have been used to model competing-risk survival data. In this article, we first show the connection and differences between crude cause-specific survival in the presence of other causes and net survival in the absence of other causes. The mixture survival model is extended to population-based grouped survival data to estimate the personal cure rate. Using the colorectal cancer survival data from the Surveillance, Epidemiology and End Results Programme, we estimate the probabilities of dying from colorectal cancer, heart disease, and other causes by age at diagnosis, race and American Joint Committee on Cancer stage.

    The objective of this study was to determine if ovarian cancer patients with a TP53 mutation grouped by location of the mutation within the p53 protein structure exhibit differential survival outcomes. Data from patients with high grade serous ovarian cancer (HGS OvCa) (N = 316) or breast cancer (BrCa) (N = 981) sequenced by The Cancer Genome Atlas (TCGA) was studied by Kaplan-Meier and Cox proportional hazards survival analysis. A TP53 DNA binding domain (BD) missense mutation (MM) occurred in 58.5% (185/316) of HGS OvCas and 16.8% (165/981) of BrCas. Patients with a TP53 DNA BD MM grouped by structural location had significantly different overall survival (OS) and progression free survival (PFS). Median OS (months) of HGS OvCa patients by structural group were: Sheet-loop-helix stabilizers, 31.1; DNA minor groove residue R248, 33.6; Wild-type, 34.2; all other MMs, 44.5; DNA major groove residues, 84.1, and zinc ion coordinating residues, 87.0 (log-rank p = 0.006). PFS of DNA major groove MM cases was longer than TP53 wild-type cases (19.1 versus 10.1 months, log-rank p = 0.038). HGS OvCa and BrCa patients with structurally-grouped TP53 DNA BD MMs have different survival outcomes.

    Evidence supports the contribution of depression, anxiety, and poor social support to mortality of hospitalized myocardial infarction (MI) patients. The contribution of depression to survival is independent of disease severity. Pet ownership, a non-human form of social support, has also been associated with one year survival of post-MI patients. The current study addresses whether pet ownership contributes independently to long term survival beyond the contributions of depression, anxiety, or low social support in post-MI patients who have already survived at least 6 months. Data from patients (N = 460) enrolled in the “Psychosocial Responses in the Home Automated External Defibrillator Trial (PR-HAT)”were used. Seventeen patients died during a median follow-up of 2.8 years. In Cox proportional hazards regression model that included depression, lack of pet ownership, and the interaction between depression and lack of pet ownership, not owning a pet was the only significant independent predictor of mortality (p = 0.036). The interaction between pet ownership and depression tended to be significant indicating that the effect of pet ownership on survival in this group of people who have supportive spouses/companions living with them may relate to depression.

    ABSTRACT Objective To evaluate the epidemiological profile and overall survival of a large population of elderly individuals diagnosed with solid tumors in a tertiary hospital. Methods This retrospective study included patients aged >65 years, diagnosed with solid tumors between January 2007 and December 2011, at Hospital Israelita Albert Einstein, São Paulo, Brazil. The medical records were reviewed to obtain information about clinical variables and overall survival. Results A total of 806 patients were identified, and 58.4% were male. Mean age was 74 years (65 to 99 years). The most common types were prostate (22%), colorectal (21%), breast (19%), and lung cancer (13%), followed by bladder (8%), pancreas (6%), and other types (11%). The majority of patients were diagnosed at early stage disease. After a median follow-up of 27 months (15 to 45 months), 29% of the patients (234/806) died, predominantly in the group older than 70 years. For the entire cohort, the median 2-year survival rate was 71%. Median overall survival was not reached within the study period. In a multivariate analysis, age (HR: 1.35; 95%CI: 1.25-1.45; p<0.001) and disease stage (HR: 1.93; 95%CI: 1.75-2.14; p<0.001) were independent negative predictors of poor survival. Conclusion The most prevalent tumors were prostate, colorectal, breast, and lung cancer, with the larger proportion diagnosed at initial stages, reflecting the great number of patients alive at last follow-up.

    A systematic review of the neurologic literature identified 433 cases of pathologically proven multiple system atrophy over a 100-year period. Earlier case reports included patients younger in age with more frequent cerebellar involvement. Mean age of onset was 54.2 years (range 31 to 78) and survival was 6.2 years (range 0.5 to 24). Survival analysis showed a secular trend from a median duration of 4.9 years for publications between 1887 and 1970 to 6.8 years between 1991 and 1994. Older age of onset was associated with shorter survival; the hazard ratio for patients with onset after 60 years was 1.8 (95% CI 1.4 to 2.3) compared with patients between 31 and 49 years. Cerebellar features were associated with marginally increased survival (6.1 years versus 5.4 years; p = 0.04). There were no difference in survival according to gender, parkinsonian, or pyramidal features or whether the patient was classified as striatonigral degeneration or olivopontocerebellar atrophy type. These results demonstrate the poor prognosis for patients with multiple system atrophy but may be biased toward the worst cases. Future research needs to recruit more representative samples.

    The survival rate of 42 patients with cystic fibrosis diagnosed during the five year period before institution of full prophylactic aerosol, mist tent and postural drainage therapy in 1967 was compared with that of 32 cases diagnosed in the five following years. The mean survival rate of the latter group was 81%, 81% and 73% at 1, 2 and 3 years respectivly, compared with 64%, 59% and 57% in the former group. The main difference was due to the significantly improved survival rate of cases diagnosed during the first year of life.

    Blood transfusion and iron chelation currently represent a supportive therapy to manage anemia, vasculopathy and vaso-occlusion crises in Sickle-Cell-Disease. Here we describe the first 5-year long-term randomized clinical trial comparing Deferiprone versus Deferoxamine in patients with Sickle-Cell-Disease. The results of this study show that Deferiprone has the same effectiveness as Deferoxamine in decreasing body iron burden, measured as repeated measurements of serum ferritin concentrations on the same patient over 5-years and analyzed according to the linear mixed-effects model (LMM) (p=0.822). Both chelators are able to decrease, significantly, serum ferritin concentrations, during 5-years, without any effect on safety (p=0.005). Moreover, although the basal serum ferritin levels were higher in transfused compared with non-transfused group (p=0.031), the changes over time in serum ferritin levels were not statistically significantly different between transfused and non-transfused cohort of patients (p=0.389). Kaplan-Meier curve, during 5-years of study, suggests that Deferiprone does not alter survival in comparison with Deferoxamine (p=0.38). In conclusion, long-term iron chelation therapy with Deferiprone was associated with efficacy and safety similar to that of Deferoxamine. Therefore, in patients with Sickle-Cell-Disease, Deferiprone may represent an effective long-term treatment option.

    Nausea and vomiting of pregnancy (NVP) affects up to 85% of pregnant women, with varying degrees of severity. The most severe form of NVP, known as hyperemesis gravidarum (HG), affects up to 2% of pregnancies. Women who have suffered with severe NVP/HG in a previous pregnancy have a 75-85% recurrence rate. Both patients and physicians often fear the use of pharmacological therapies during pregnancy due to the concerns of potential risks to the fetus. The symptoms and impact of NVP and HG can vary greatly among women, therefore treatment must be tailored to the individual. Updated Motherisk guidelines are presented.

    Metformin has garnered considerable interest as a chemo-preventive and chemo-therapeutic agent given the increased risk of liver cancer among diabetic patients. This work was performed to illustrate the association between metformin use and survival of diabetic liver cancer patients. We conducted a comprehensive literature search of PubMed, Web of Science, Embase, BIOSIS Previews, Cochrane Library from inception to 12 May 2016. Meta-analyses were performed using Stata (version 12.0), with hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) as effect measures. Eleven cohort studies involving 3452 liver cancer patients fulfilled the inclusion criteria. Meta-analyses showed that metformin use was associated with better survival (HR = 0.59; 95% CI, 0.42-0.83; p = 0.002) of liver cancer patients, and the beneficial effect persisted (HR = 0.64; 95% CI, 0.42-0.97; p = 0.035) when the population was restricted to diabetic liver cancer patients. After adjusting for age, etiology, index of tumor severity and treatment of liver cancer, the association between metformin use and better survival of liver cancer patients was stable, pooled HR ranged from 0.47 to 0.57. The results indicated that metformin use improved survival of diabetic liver cancer patients. However, the results should be interpreted with caution given the possibility of residual confounding. Further prospective studies are still needed to confirm the prognostic benefit of metformin use. PMID:27494848

    Purpose: To evaluate whether complex radiotherapy (RT) planning was associated with improved outcomes in a cohort of elderly patients with unresected Stage I-II non-small-cell lung cancer (NSCLC). Methods and Materials: Using the Surveillance, Epidemiology, and End Results registry linked to Medicare claims, we identified 1998 patients aged >65 years with histologically confirmed, unresected stage I-II NSCLC. Patients were classified into an intermediate or complex RT planning group using Medicare physician codes. To address potential selection bias, we used propensity score modeling. Survival of patients who received intermediate and complex simulation was compared using Cox regression models adjusting for propensity scores and in a stratified and matched analysis according to propensity scores. Results: Overall, 25% of patients received complex RT planning. Complex RT planning was associated with better overall (hazard ratio 0.84; 95% confidence interval, 0.75-0.95) and lung cancer-specific (hazard ratio 0.81; 95% confidence interval, 0.71-0.93) survival after controlling for propensity scores. Similarly, stratified and matched analyses showed better overall and lung cancer-specific survival of patients treated with complex RT planning. Conclusions: The use of complex RT planning is associated with improved survival among elderly patients with unresected Stage I-II NSCLC. These findings should be validated in prospective randomized controlled trials.

    MicroRNAs as biomarkers play an important role in the tumorigenesis process, including hepatocellular carcinomas (HCCs). In this paper, we used The Cancer Genome Atlas (TCGA) database to mine hepatitis B-related liver cancer microRNAs that could predict survival in patients with hepatitis B-related liver cancer. There were 93 cases of HBV-HCC and 49 cases of adjacent normal controls included in the study. Kaplan–Meier survival analysis of a liver cancer group versus a normal control group of differentially expressed genes identified eight genes with statistical significance. Compared with the normal liver cell line, hepatocellular carcinoma cell lines had high expression of 8 microRNAs, albeit at different levels. A Cox proportional hazards regression model for multivariate analysis showed that four genes had a significant difference. We established classification models to distinguish short survival time and long survival time of liver cancers. Eight genes (mir9-3, mir10b, mir31, mir519c, mir522, mir3660, mir4784, and mir6883) were identified could predict survival in patients with HBV-HCC. There was a significant correlation between mir10b and mir31 and clinical stages (p < 0.05). A random forests model effectively estimated patient survival times. PMID:28322348

    Purpose: The Dutch Bone Metastases Study Group developed a survival prediction model in patients with symptomatic spinal bone metastases to guide the treating physician. The objective of this study was to validate the Dutch model and compare with our previously developed survival model at the Rapid Response Radiotherapy Program (RRRP model). Methods and Materials: The following prognostic factors were extracted from a prospective database in an outpatient palliative radiotherapy clinic: Karnofsky Performance Scores (KPS), primary cancer site, and visceral involvement for the Dutch model; primary cancer site, site of metastases, KPS, fatigue, appetite, and shortness of breath scores in the Edmonton Symptom Assessment Scale for the RRRP model. Patients were assigned scores according to each model. The survival probabilities were generated and calibration was performed for each model. Results: A total of 231 patients with spinal bone metastases from 1999 and 2002 were included in the analysis. The survival probabilities were similar to those in the original models. The calibration comparing actual survival with predicted survival from the Dutch and RRRP models gave R{sup 2} values of 0.90 and 0.86, respectively. Conclusion: The two models were successfully validated. The Dutch model using three clinical prognostic factors was easier to administer.

    Recently, TROG 02.01 results showed that in stage III melanoma patients with nodal metastasis, adjuvant radiation to lymph node basin after nodal dissection improves lymph node field relapse without an overall survival (OS) benefit. However, this trial was neither designed nor powered to detect an OS difference. In the present study, we analyzed patients in the National Cancer Database (NCDB) with stage III melanoma with pathologically involved nodes and compared survival outcomes of adjuvant radiation and no-radiation cohorts. Inclusion criteria were as follows: age at least 18 years; diagnosed 2003–2011; surgery to regional lymph nodes; pathologically involved lymph nodes; and American Joint Committee on Cancer stage (IIIA-C). We used propensity score matching analysis to compare the OS of patients with similar baseline demographic, clinical, and pathologic characteristics who received adjuvant radiation and no adjuvant radiation. Overall, 912 patients were analyzed with an average age at diagnosis of 54.4 years and a median follow-up time of 5.5 years. In this cohort, the 5-year OS was 69.0, 51.1, and 30.6% for stage IIIA, IIIB, and IIIC, respectively. On propensity score-adjusted multivariate analysis, we found that adjuvant radiation had no statistically significant impact on OS (hazard ratio: 1.09, 95% confidence interval: 0.75–1.58, P=0.640). Furthermore, age older than 60 years, number of nodes, increasing pathologic stage, and absence of immunotherapy correlated with worse OS. In this NCDB analysis, we found that the adjuvant radiotherapy for node-positive, stage III melanoma patients did not improve OS. This is consistent with TROG 02.01; however, there may be patient selection bias not accounted for by the NCDB. PMID:27575390

    Background and purpose A rapid learning approach has been proposed to extract and apply knowledge from routine care data rather than solely relying on clinical trial evidence. To validate this in practice we deployed a previously developed decision support system (DSS) in a typical, busy clinic for non-small cell lung cancer (NSCLC) patients. Material and methods Gender, age, performance status, lung function, lymph node status, tumor volume and survival were extracted without review from clinical data sources for lung cancer patients. With these data the DSS was tested to predict overall survival. Results 3919 lung cancer patients were identified with 159 eligible for inclusion, due to ineligible histology or stage, non-radical dose, missing tumor volume or survival. The DSS successfully identified a good prognosis group and a medium/poor prognosis group (2 year OS 69% vs. 27/30%, p < 0.001). Stage was less discriminatory (2 year OS 47% for stage I–II vs. 36% for stage IIIA–IIIB, p = 0.12) with most good prognosis patients having higher stage disease. The DSS predicted a large absolute overall survival benefit (~40%) for a radical dose compared to a non-radical dose in patients with a good prognosis, while no survival benefit of radical radiotherapy was predicted for patients with a poor prognosis. Conclusions A rapid learning environment is possible with the quality of clinical data sufficient to validate a DSS. It uses patient and tumor features to identify prognostic groups in whom therapy can be individualized based on predicted outcomes. Especially the survival benefit of a radical versus non-radical dose predicted by the DSS for various prognostic groups has clinical relevance, but needs to be prospectively validated. PMID:25241994

    Survival of patients with metastatic renal cell carcinoma (mRCC) has improved since the advent of targeted therapy. Approved agents include the multi-targeted tyrosine kinase inhibitors (TKIs) sunitinib, sorafenib, axitinib, pazopanib, cabozantinib, and lenvatinib (approved in combination with everolimus), the anti-VEGF monoclonal antibody bevacizumab, the mammalian target of rapamycin (mTOR) inhibitors everolimus and temsirolimus, and the programmed death-1 (PD-1) targeted immune checkpoint inhibitor nivolumab. The identification of predictive and prognostic factors of survival is increasing, and both clinical predictive factors and pathology-related prognostic factors are being evaluated. Serum-based biomarkers and certain histologic subtypes of RCC, as well as clinical factors such as dose intensity and the development of some class effect adverse events, have been identified as predictors of survival. Expression levels of microRNAs, expression of chemokine receptor 4, hypermethylation of certain genes, VEGF polymorphisms, and elevation of plasma fibrinogen or d-dimer have been shown to be prognostic indicators of survival. In the future, prognosis and treatment of patients with mRCC might be based on genomic classification, especially of the 4 most commonly mutated genes in RCC (VHL, PBRM1, BAP1, and SETD2). Median overall survival has improved for patients treated with a first-line targeted agent compared with survival of patients treated with first-line interferon-α, and results of clinical trials have shown a survival benefit of sequential treatment with targeted agents. Prognosis of patients with mRCC will likely improve with optimization and individualization of current sequential treatment with targeted agents.

    Purpose: To retrospectively evaluate the role of postoperative chemoradiotherapy (POCRT) in patients with completely resected non-small-cell lung cancer (NSCLC) with N2 lymph node involvement. Methods and Materials: This study included 183 patients from four centers in southwest China who underwent radical section of Stage III-N2 NSCLC without any preoperative therapy. One hundred and four were treated with POCRT and 79 with postoperative chemotherapy (POCT) alone. The median radiation dose to clinical target volume (CTV) was 50 Gy (varying between 48 and 54 Gy), whereas the cycles of platinum-based chemotherapy ranged from two to six with a median of four. Results: The median duration of follow-up was 72 months. The 5-year overall survival rate (OS) was 30.5% in the POCRT group, and 14.4% in the POCT group (p = 0.007). The 5-year disease-free survival rate (DFS) was 22.2% in POCRT group and 9.3% in POCT group (p = 0.003). In a multivariate analysis, N1 nodal involvement (N1+/N2+) was associated with significantly worse OS (HR = 1.454, 95% CI, 1.012-2.087, p = 0.043) and DFS (HR = 1.685, 95% CI, 1.196-2.372, p = 0.003). Absence of radiotherapy and treatment with fewer than three cycles of chemotherapy both were poor prognostic factors for both OS and DFS. Conclusions: As compared with chemotherapy alone, adjuvant treatment with both radiotherapy and chemotherapy improves survival in patients with completely resected Stage III-N2 nodal disease in NSCLC. Future study of treatment modality with radiotherapy and chemotherapy is warranted, especially focusing on both N1 and N2 nodal status.

    The multifunctional molecule netrin-1 is upregulated in various malignancies and has recently been presented as a major general player in tumorigenesis leading to tumor progression and maintenance in various animal models. However, there is still a lack of clinico-epidemiological data related to netrin-1 expression. Therefore, the aim of our study was to elucidate the association of netrin-1 expression and patient survival in brain metastases since those constitute one of the most limiting factors for patient prognosis. We investigated 104 brain metastases cases for netrin-1 expression using in-situ hybridization and immunohistochemistry with regard to clinical parameters such as patient survival and MRI data. Our data show that netrin-1 is strongly upregulated in most cancer subtypes. Univariate analyses revealed netrin-1 expression as a significant factor associated with poor patient survival in the total cohort of brain metastasis patients and in sub-entities such as non-small cell lung carcinomas. Interestingly, many cancer samples showed a strong nuclear netrin-1 signal which was recently linked to a truncated netrin-1 variant that enhances tumor growth. Nuclear netrin-1 expression was associated with poor patient survival in univariate as well as in multivariate analyses. Our data indicate both total and nuclear netrin-1 expression as prognostic factors in brain metastases patients in contrast to other prognostic markers in oncology such as patient age, number of brain metastases or Ki67 proliferation index. Therefore, nuclear netrin-1 expression constitutes one of the first reported molecular biomarkers for patient survival in brain metastases. Furthermore, netrin-1 may constitute a promising target for future anti-cancer treatment approaches in brain metastases. PMID:24647424

    Background/Aims Most patients with dementia suffer from dysphagia in the terminal stage of the disease. In Japan, most elderly patients with dysphagia receive either tube feeding or total parenteral nutrition. Methods In this study, we investigated the factors determining longer survival with artificial nutrition. Various clinical characteristics of 168 inpatients receiving artificial nutrition without oral intake in psychiatric hospitals in Okayama Prefecture, Japan, were evaluated. Results Multiple logistic regression analysis showed that the duration of artificial nutrition was associated with a percutaneous endoscopic gastrostomy (PEG) tube, diagnosis of mental disorder, low MMSE score, and absence of decubitus. Conclusion Patients with mental disorders survived longer than those with dementia diseases on artificial nutrition. A PEG tube and good nutrition seem to be important for long-term survival.

    Background Persons living after a cancer diagnosis represent 4% of the whole population in high-income countries. The aim of the study was to provide estimates of indicators of long-term survival and cure for 26 cancer types, presently lacking. Patients and methods Data on 818 902 Italian cancer patients diagnosed at age 15–74 years in 1985–2005 were included. Proportions of patients with the same death rates of the general population (cure fractions) and those of prevalent patients who were not at risk of dying as a result of cancer (cure prevalence) were calculated, using validated mixture cure models, by cancer type, sex, and age group. We also estimated complete prevalence, conditional relative survival (CRS), time to reach 5- and 10-year CRS >95%, and proportion of patients living longer than those thresholds. Results The cure fractions ranged from >90% for patients aged <45 years with thyroid and testis cancers to <10% for liver and pancreatic cancers of all ages. Five- or 10-year CRS >95% were both reached in <10 years by patients with cancers of the stomach, colon–rectum, pancreas, corpus and cervix uteri, brain, and Hodgkin lymphoma. For breast cancer patients, 5- and 10-year CRSs reached >95% after 19 and 25 years, respectively, and in 15 and 18 years for prostate cancer patients. Five-year CRS remained <95% for >25 years after cancer diagnosis in patients with liver and larynx cancers, non-Hodgkin lymphoma, myeloma, and leukaemia. Overall, the cure prevalence was 67% for men and 77% for women. Therefore, 21% of male and 31% of female patients had already reached 5-year CRS >95%, whereas 18% and 25% had reached 10-year CRS >95%. Conclusions A quarter of Italian cancer patients can be considered cured. This observation has a high potential impact on health planning, clinical practice, and patients' perspective. PMID:25149707

    We conducted a prospective study to establish factors associated with survival in tuberculosis patients in Russia including social, clinical and pathogen-related genetic parameters. Specifically we wished to determine whether different strains/clades of the Beijing lineage exerted a differential effect of survival. HIV-negative culture-confirmed cases were recruited during 2008-2010 across Samara Oblast and censored in December 2011. Molecular characterization was performed by a combination of spoligotyping, multilocus VNTR typing and whole genome sequencing (WGS). We analyzed 2602 strains and detected a high prevalence of Beijing family (n=1933; 74%) represented largely by two highly homogenous dominant clades A (n=794) and B (n=402) and non-A/non-B (n=737). Multivariable analysis of 1366 patients with full clinical and genotyping data showed that multi- and extensive drug resistance (HR=1.86; 95%CI: 1.52, 2.28 and HR=2.19; 95%CI: 1.55, 3.11) had the largest impact on survival. In addition older age, extensive lung damage, shortness of breath, treatment in the past and alcohol abuse reduced survival time. After adjustment for clinical and demographic predictors there was evidence that clades A and B combined were associated with poorer survival than other Beijing strains (HR=0.48; 95%CI 0.34, 0.67). All other pathogen-related factors (polymorphisms in genes plcA, plcB, plcC, lipR, dosT and pks15/1) had no effect on survival. In conclusion, drug resistance exerted the greatest effect on survival of TB patients. Nevertheless we provide evidence for the independent biological effect on survival of different Beijing family strains even within the same defined geographical population. Better understanding of the role of different strain factors in active disease and their influence on outcome is essential.

    The control and treatment of dyslipidemia is a major public health challenge, particularly for patients with coronary heart diseases. In this paper we propose a framework for survival analysis of patients who had a major cardiac event, focusing on assessment of the effect of changing LDL-cholesterol level and statins consumption on survival. This framework includes a Cox PH model and a Markov chain, and combines their results into reinforced conclusions regarding the factors that affect survival time. We prospectively studied 2,277 cardiac patients, and the results show high congruence between the Markov model and the PH model; both evidence that diabetes, history of stroke, peripheral vascular disease and smoking significantly increase hazard rate and reduce survival time. On the other hand, statin consumption is correlated with a lower hazard rate and longer survival time in both models. The role of such a framework in understanding the therapeutic behavior of patients and implementing effective secondary and primary prevention of heart diseases is discussed here.

    To determine the prevalence of depression, to identify correlated factors for depression, and to explore the impact on the progression or survival of amyotrophic lateral sclerosis (ALS) by depression in a Chinese population. A total of 166 ALS patients were recruited. Diagnosis of depression disorders and the severity of depression were established by using the fourth diagnostic and statistical manual of mental disorders, Hamilton Depression Rating Scale-24 items (HDRS-24) and Beck Depression Inventory (BDI). Major depression was found in 15 patients (9.6 %). The multiple regression analysis showed that a lower ALS Functional Rating Scale-Revised (ALSFRS-R) score was correlated with increasing HDRS scores and BDI scores (P = 0.018 and P = 0.012). No significant difference in the median survival time between ALS patients with and without depression was revealed by Kaplan-Meier analysis (log-rank P = 0.282). Cox hazard model showed that the presence of depression in ALS was unrelated to the survival, while the severity of depression in ALS was correlated with the survival. The presence and severity of depression in ALS did not correlate with the progression of ALS. Major depression in ALS is uncommon. Depression evaluation should be given to ALS patients, especially those with lower ALSFRS-R score. The severity of depression may be associated with the survival; however, depression does not worse the progression of ALS.

    Malnutrition and inflammation are related to high rates of morbidity and mortality in hemodialysis patients. Resistin is associated with nutrition and inflammation. We attempted to determine whether resistin levels may predict clinical outcomes in hemodialysis patients. We conducted a prospective evaluation of 100 outpatients on hemodialysis in a single dialysis center (male, 46%; mean age, 53.7 ± 16.4 yr). We stratified the patients into 4 groups according to quartiles of serum resistin levels. During the 18-month observational period, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival (log rank test, P = 0.016). After adjustment of all co-variables, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival, compared with reference resistin levels. Higher levels of interleukin-6 were an independent predictor of poor hospitalization-free survival. In contrast, serum resistin levels were not correlated with interleukin-6 levels. The current data showed that low resistin levels may independently predict poor hospitalization free survival in hemodialysis patients. PMID:22468100

    Abstract Sepsis-related multiple organ dysfunction syndrome is a leading cause of death in intensive care units. There is overwhelming evidence that oxidative stress plays a significant role in the pathogenesis of sepsis-associated multiple organ failure; however, reactive oxygen species (ROS)–associated biomarkers and/or diagnostics that define mortality or predict survival in sepsis are lacking. Lung or peripheral blood gene expression analysis has gained increasing recognition as a potential prognostic and/or diagnostic tool. The objective of this study was to identify ROS-associated biomarkers predictive of survival in patients with sepsis. In-silico analyses of expression profiles allowed the identification of a 21-gene ROS-associated molecular signature that predicts survival in sepsis patients. Importantly, this signature performed well in a validation cohort consisting of sepsis patients aggregated from distinct patient populations recruited from different sites. Our signature outperforms randomly generated signatures of the same signature gene size. Our findings further validate the critical role of ROSs in the pathogenesis of sepsis and provide a novel gene signature that predicts survival in sepsis patients. These results also highlight the utility of peripheral blood molecular signatures as biomarkers for predicting mortality risk in patients with sepsis, which could facilitate the development of personalized therapies.

    The impact of human immunodeficiency virus (HIV) coinfection on the survival of patients with hepatitis C virus (HCV)-related end-stage liver disease (ESLD) is unknown. Because HIV infection is no longer considered an absolute contraindication for liver transplantation in some countries, it has become a priority to address this topic. The objective of this study was to compare the survival of HIV-infected and HIV-uninfected patients with decompensated cirrhosis due to HCV. In a retrospective cohort study, the survival of 1,037 HCV monoinfected and 180 HCV/HIV-coinfected patients with cirrhosis after the first hepatic decompensation was analyzed. Of the group, 386 (37%) HCV-monoinfected and 100 (56%) HCV/HIV-coinfected subjects died during the follow-up. The median survival time of HIV-infected and HIV-uninfected patients was 16 and 48 months, respectively (P < .001). The relative risk (95% CI) of death for HIV-infected patients was 2.26 (1.51-3.38). Other independent predictors of survival were age older than 63 years (2.25 [1.53-3.31]); Child-Turcotte-Pugh class B versus class A (1.95 [1.41-2.68]) and class C versus class A (2.78 [1.66-4.70]); hepatitis D virus infection (1.56 [1.12-4.77]); model for end-stage liver disease score, (1.05 [1.01-1-11]); more than one simultaneous decompensation (1.23 [1.12-3.33]); and the type of the first hepatic decompensation, with a poorer prognosis associated with encephalopathy compared with portal hypertensive gastrointestinal bleeding (2.03 [1.26-3.10]). In conclusion, HIV coinfection reduces considerably the survival of patients with HCV-related ESLD independently of other markers of poor prognosis. This fact must be taken into account to establish the adequate timing of liver transplantation in HIV-coinfected subjects.

    Background To compare the clinicopathologic characteristics and survival of Chinese and Caucasian esophageal cancer (EC) patients residing in the US, using a population-based national registry (Surveillance Epidemiology and End Results [SEER]) database. Methods Patients with EC were identified from the SEER program from 1988 to 2012. Kaplan–Meier survival methods and Cox proportional hazards regression were performed. Results A total of 479 Chinese and 35,748 Caucasian EC patients were identified. Compared with Caucasian patients, the Chinese patients had a later year of diagnosis, remained married after EC was diagnosed, had esophageal squamous cell carcinomas (ESCCs) more frequently, had tumors located in the upper-third and middle-third of the esophagus more frequently, and fewer patients presented with poorly/undifferentiated EC and underwent cancer-directed surgery. In Chinese patients, the incidence of esophageal adenocarcinomas (EACs) increased from 1988 to 2012 (P=0.054), and the majority of EAC patients had tumors located in the lower thoracic esophagus. The overall survival (OS) was not significantly different between Chinese and Caucasian patients (P=0.767). However, Chinese patients with ESCC had a significantly better OS when compared to their Caucasian counterparts, whereas there was no significant difference in the OS between Chinese and Caucasian patients with EAC. Conclusion The presenting demographic features, tumor characteristics, and outcomes of EC patients differed between Chinese and Caucasian patients residing in the US. Chinese patients diagnosed with EAC tended to share similar clinical features with their Caucasian counterparts, and the Chinese patients with ESCC had better OS than their Caucasian counterparts.

    Purpose: To investigate whether single nucleotide polymorphisms (SNPs) in the ataxia telangiectasia mutated (ATM) gene are associated with survival in patients with esophageal squamous cell carcinoma (ESCC) receiving radiation therapy or chemoradiation therapy or surgery only. Methods and Materials: Four tagSNPs of ATM were genotyped in 412 individuals with clinical stage III or IV ESCC receiving radiation therapy or chemoradiation therapy, and in 388 individuals with stage I, II, or III ESCC treated with surgery only. Overall survival time of ESCC among different genotypes was estimated by Kaplan-Meier plot, and the significance was examined by log-rank test. The hazard ratios (HRs) and 95% confidence intervals (CIs) for death from ESCC among different genotypes were computed by a Cox proportional regression model. Results: We found 2 SNPs, rs664143 and rs664677, associated with survival time of ESCC patients receiving radiation therapy. Individuals with the rs664143A allele had poorer median survival time compared with the rs664143G allele (14.0 vs 20.0 months), with the HR for death being 1.45 (95% CI 1.12-1.89). Individuals with the rs664677C allele also had worse median survival time than those with the rs664677T allele (14.0 vs 23.5 months), with the HR of 1.57 (95% CI 1.18-2.08). Stratified analysis showed that these associations were present in both stage III and IV cancer and different radiation therapy techniques. Significant associations were also found between the SNPs and locosregional progression or progression-free survival. No association between these SNPs and survival time was detected in ESCC patients treated with surgery only. Conclusion: These results suggest that the ATM polymorphisms might serve as independent biomarkers for predicting prognosis in ESCC patients receiving radiation therapy.

    Abstract Background: Renin–angiotensin system inhibitors (RAS inhibitors) are antihypertensive agents with potential antitumor effects. However, various studies have yielded conflicting results on the influence of RAS inhibitors on survival of cancer patients. The aim of this study was to evaluate the effect of RAS inhibitors on recurrence, metastasis, and survival in cancer patients through a meta-analysis. Methods: PubMed, Web of Science, EMBASE, and Cochrane Library were systematically searched from inception to December 2016. The pooled hazard ratio (HR) with its 95% confidence interval (95% CI) was calculated to evaluate the association between RAS inhibitors and recurrence, metastasis, and survival in cancer patients. Results: Fifty-five eligible studies were included in the present meta-analysis. Results showed that there were significant improvements in overall survival (OS) (HR = 0.82; 95% CI: 0.77–0.88; P < 0.001), progression-free survival (HR = 0.74; 95% CI: 0.66–0.84; P < 0.001), and disease-free survival (HR = 0.80; 95% CI: 0.67–0.95; P = 0.01) in RAS inhibitor users compared with nonusers. Subgroup analyses revealed that the effect of RAS inhibitors on OS depended on the cancer type or different RAS inhibitors. Conclusion: This meta-analysis suggests that RAS inhibitors could improve the survival of cancer patients and depend on cancer type and types of RAS inhibitors. PMID:28353566

    Background/Aims We investigated whether transthoracic echocardiography-suspected pulmonary hypertension (PH) affects survival in systemic lupus erythematosus (SLE) patients and examined factors associated with PH occurrence and survival. Methods This retrospective single-center study included 154 Korean SLE patients fulfilling the American College of Rheumatology criteria (January 1995 to June 2013). Student t test, Mann-Whitney U test, Kaplan-Meier curves, and log-rank tests were used for comparisons. Results A total of 35 SLE patients with PH (SLE/PH+) and 119 without PH (SLE/PH-) were analyzed. Higher percentages of interstitial lung disease, Raynaud's phenomenon (RP), World Health Organization functional classification III/IV, and cardiomegaly were found in SLE/PH+ compared to SLE/PH-. Furthermore, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index was significantly higher in SLE/PH+ (2.46 ± 1.245 vs. 1.00 ± 1.235), whereas survival rates were significantly higher in SLE/PH- in log-rank tests (p = 0.001). In multivariate analysis, the adjusted mortality hazard ratio (HR) for SLE/PH+ patients was 3.10. Subgroup analysis demonstrated a higher percentage of lupus nephritis in the SLE/PH+ patients who died (p = 0.039) and low complement-3 levels (p = 0.007). In univariate analysis, the mortality HR for SLE/PH+ patients with lupus nephritis was 4.62, whereas the presence of RP decreased the mortality risk in multivariate analysis; adjusted HR, 0.10. Conclusions PH is an independent factor predicting survival in SLE patients. The presence of lupus nephritis resulted in an increased trend for mortality, whereas coexistence of RP was associated with a better survival prognosis in SLE/PH+ patients. PMID:25750566

    Pulmonary arterial dissection is an extremely rare and usually lethal complication of chronic pulmonary hypertension. The condition usually manifests as cardiogenic shock or sudden death and is therefore typically diagnosed at postmortem examination rather than during life. However, recent isolated reports have described pulmonary artery dissection in surviving patients. The first case of pulmonary artery dissection in a surviving patient with cor pulmonale caused by chronic obstructive pulmonary disease is presented. The aetiology, pathophysiology, and clinical presentation of pulmonary artery dissection are reviewed and factors that may aid diagnosis during life are discussed.

    Abstract Several studies have suggested an association between use of metformin and an increased overall survival in patients diagnosed with pancreatic cancer, however with several important methodological limitations. The aim of the study was to assess the association between overall survival, pancreatic cancer, and metformin use. A retrospective cohort study of 1111 patients with pancreatic cancer was conducted using data from The Netherlands Comprehensive Cancer Organization (1998–2011). Data were linked to the PHARMO Database Network containing drug-dispensing records from community pharmacies. Patients were classified as metformin user or sulfonylurea derivatives user from the moment of first dispensing until the end of follow up. The difference in overall survival between metformin users and nonusers was assessed, and additionally between metformin users and sulfonylurea derivatives users. Univariable and multivariable parametric survival models were used and use of metformin and sulfonylurea derivatives was included as time-varying covariates. Of the 1111 patients, 91 patients were excluded because of differences in morphology, 48 patients because of using merely metformin before diagnosis, and 57 metformin-users ever used contemporary sulfonylurea derivatives and were therefore excluded. Lastly, 8 patients with a survival of zero months were excluded. This resulted in 907 patients for the analysis. Overall, 77 users of metformin, 43 users of sulfonylurea derivatives, and 787 nonusers were identified. The adjusted rate ratio for overall survival for metformin users versus nonusers was 0.86 (95% CI: 0.66–1.11; P = 0.25). The difference in overall survival between metformin users and sulfonylurea derivatives users showed an adjusted rate ratio of 0.90 (95% CI: 0.59–1.40; P = 0.67). No association was found between overall survival, pancreatic cancer, and metformin use. This was in concordance with 2 recently published randomized controlled trials

    The combination of fludarabine, cytarabine, idarubicin, and granulocyte colony-stimulating factor (FLAG-Ida) is widely used in relapsed/refractory acute myeloid leukaemia (AML). We retrospectively analysed the results of 259 adult AML patients treated as first salvage with FLAG-Ida or FLAG-Ida plus Gentuzumab-Ozogamicin (FLAGO-Ida) of the Programa Español de Tratamientos en Hematología (PETHEMA) database, developing a prognostic score system of survival in this setting (SALFLAGE score). Overall, 221 patients received FLAG-Ida and 38 FLAGO-Ida; 92 were older than 60 years. The complete remission (CR)/CR with incomplete blood count recovery (CRi) rate was 51%, with 9% of induction deaths. Three covariates were associated with lower CR/CRi: high-risk cytogenetics and t(8;21) at diagnosis, no previous allogeneic stem cell transplantation (allo-SCT) and relapse-free interval <1 year. Allo-SCT was performed in second CR in 60 patients (23%). The median overall survival (OS) of the entire cohort was 0·7 years, with 22% OS at 5-years. Four independent variables were used to construct the score: cytogenetics, FLT3-internal tandem duplication, length of relapse-free interval and previous allo-SCT. Using this stratification system, three groups were defined: favourable (26% of patients), intermediate (29%) and poor-risk (45%), with an expected 5-year OS of 52%, 26% and 7%, respectively. The SALFLAGE score discriminated a subset of patients with an acceptable long-term outcome using FLAG-Ida/FLAGO-Ida regimen. The results of this retrospective analysis should be validated in independent external cohorts.

    Our objective was to elucidate the clinical factors affecting functional decline and survival in Japanese amyotrophic lateral sclerosis (ALS) patients. We constructed a multicenter prospective ALS cohort that included 451 sporadic ALS patients in the analysis. We longitudinally utilized the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) as the functional scale, and determined the timing of introduction of a tracheostomy for positive-pressure ventilation and death. A joint modelling approach was employed to identify prognostic factors for functional decline and survival. Age at onset was a common prognostic factor for both functional decline and survival (p < 0.001, p < 0.001, respectively). Female gender (p = 0.019) and initial symptoms, including upper limb weakness (p = 0.010), lower limb weakness (p = 0.008) or bulbar symptoms (p = 0.005), were related to early functional decline, whereas neck weakness as an initial symptom (p = 0.018), non-use of riluzole (p = 0.030) and proximal dominant muscle weakness in the upper extremities (p = 0.01) were related to a shorter survival time. A decline in the ALSFRS-R score was correlated with a shortened survival time (p < 0.001). In conclusion, the factors affecting functional decline and survival in ALS were common in part but different to some extent. This difference has not been previously well recognized but is informative in clinical practice and for conducting trials.

    Abstract Background: Radiation exposure is an established risk factor for bladder cancer, however consensus is lacking on the survival characteristics of bladder cancer patients with a history of radiation therapy (RT). Confounding patient comorbidities and baseline characteristics hinders prior attempts at developing such a consensus. Objective: To compare the survival characteristics of patients with suspected radiation-induced second primary cancer (RISPC) of the bladder to those with de novo bladder cancer, taking into account the patient comorbidities and baseline characteristics predictive of survival. Methods: Retrospective analysis of patients with muscle-invasive (≥T2a) or BCG-refractory stage Tis-T1 urothelial bladder cancer. Patients were excluded if prior RT exposure was used as treatment for bladder cancer or if cause of death was due to post-operative complications. A digit matching propensity score algorithm was used to match patients with prior radiation treatment to those without prior treatment. Cox regression analysis for time until death was performed following creation of the propensity score matched sample. Results: 29 patients with history of RT were matched with two controls each, resulting in a dataset of 87 observations in the event model. Results from the Cox model indicate a significantly increased hazard ratio for death at 2.22 (p = 0.047, 95% CI: 1.015–4.860) given a history of prior radiation therapy. Conclusions: In a small cohort, bladder cancer patients who underwent cystectomy had a significantly higher risk of death in the face of prior pelvic RT. This effect was found to be independent of surgical complications, numerous established patient characteristics and comorbidities traditionally predictive of survival. PMID:27376117

    Advanced stage leiomyosarcoma (LMS) is incurable with current systemic antitumor therapies. Therefore, there is clinical interest in exploring novel therapeutic regimens to treat LMS. We reviewed the medical records of 75 consecutive patients with histologically confirmed metastatic LMS, who had been referred to the Clinical Center for Targeted Therapy at MD Anderson Cancer Center. To lay the foundation for potential phase I trials for the treatment of advanced LMS, we analyzed tumor response and survival outcome data. The frequent hotspot gene aberrations that we observed were the TP53 mutation (65%) and RB1 loss/mutation (45%) detected by Sequenom or next-generation sequencing. Among patients treated with gene aberration-related phase I trial therapy, the median progression-free survival was 5.8 months and the median overall survival was 15.9 months, significantly better than in patients without therapy (1.9 months, P = 0.001; and 8.7 months, P = 0.013, respectively). Independent risk factors that predicted shorter overall survival included hemoglobin <10 g/dL, body mass index <30 kg/m(2) , serum albumin <3.5 g/dL, and neutrophil above upper limit of normal. The median survivals were 19.9, 7.6, and 0.9 months for patients with 0, 1 or 2, and ≥3 of the above risk factors, respectively (P < 0.001). A prognostic scoring system that included four independent risk factors might predict survival in patients with metastatic LMS who were treated in a phase I trial. Gene aberration-related therapies led to significantly better clinical benefits, supporting that further exploration with novel mechanism-driven therapeutic regimens is warranted.

    Whereas the total mortality rate for sarcoidosis is 0.2 per 100,000, the prognosis, when the heart is involved, is very much worse. The authors used the difference in mortality rate to infer whether thallium 201 myocardial perfusion scan abnormalities correspond to myocardial sarcoid by making the simplifying assumption that if they do, then patients with abnormal scans will be found to have a death rate similar to patients with sarcoid heart disease. The authors therefore analyzed complete survival data on 52 sarcoid patients without cardiac symptoms an average of eighty-nine months after they had been scanned as part of a protocol. By use of survival analysis (the Cox proportional hazards model), the only variable that was significantly associated with survival was age. The patients' scan pattern, treatment status, gender, and race were not significantly related to survival. The authors conclude that thallium myocardial perfusion scans cannot reliably be used to diagnose sarcoid heart disease in sarcoid patients without cardiac symptoms.

    The main objective of this paper was to assess the influence of educational level on the survival of uterine cervix cancer patients in our population. A total of 224 patients were registered in our registry, of which 178 had information on stage and different educational levels. The overall median survival (MS) was 23 months, with values of 18.5, 20.7 and 41.3 months for the illiterate, literate and qualified groups, respectively. In the illiterate patients, stage I was seen in 2.6% and stage IV in 11.8%, while in other 2 groups stage I was seen in 10% to 17% of patients at the time of diagnosis. The survival probability at around 50 months was around 42%, 30% and 26% (approximately) for qualified, literates and illiterates respectively [Log Rank (Mantel-Cox) showed p=0.023]. Emphasis on imparting education to females can be a part of comprehensive cancer control programme for improving the overall survival in patients with carcinoma of the uterine cervix in our population.

    Background MRI characteristics of brain gliomas have been used to predict clinical outcome and molecular tumor characteristics. However, previously reported imaging biomarkers have not been sufficiently accurate or reproducible to enter routine clinical practice and often rely on relatively simple MRI measures. The current study leverages advanced image analysis and machine learning algorithms to identify complex and reproducible imaging patterns predictive of overall survival and molecular subtype in glioblastoma (GB). Methods One hundred five patients with GB were first used to extract approximately 60 diverse features from preoperative multiparametric MRIs. These imaging features were used by a machine learning algorithm to derive imaging predictors of patient survival and molecular subtype. Cross-validation ensured generalizability of these predictors to new patients. Subsequently, the predictors were evaluated in a prospective cohort of 29 new patients. Results Survival curves yielded a hazard ratio of 10.64 for predicted long versus short survivors. The overall, 3-way (long/medium/short survival) accuracy in the prospective cohort approached 80%. Classification of patients into the 4 molecular subtypes of GB achieved 76% accuracy. Conclusions By employing machine learning techniques, we were able to demonstrate that imaging patterns are highly predictive of patient survival. Additionally, we found that GB subtypes have distinctive imaging phenotypes. These results reveal that when imaging markers related to infiltration, cell density, microvascularity, and blood–brain barrier compromise are integrated via advanced pattern analysis methods, they form very accurate predictive biomarkers. These predictive markers used solely preoperative images, hence they can significantly augment diagnosis and treatment of GB patients. PMID:26188015

    Sunitinib is a tyrosine kinase inhibitor (TKI) used in treatment of metastatic renal cell carcinoma (mRCC), gastrointestinal stromal tumors and pancreatic neuroendocrine tumors. One of the most common side effects related to sunitinib is hypothyroidism. Recent trials suggest correlation between the incidence of hypothyroidism and treatment outcome in patients treated with TKI. This study evaluates whether development of hypothyroidism is a predictive marker of progression-free survival (PFS) in patients with mRCC treated with sunitinib. Twenty-seven patients diagnosed with clear cell mRCC, after nephrectomy and in 'good' or 'intermediate' MSKCC risk prognostic group, were included in the study. All patients received sunitinib as a first-line treatment on a standard schedule (initial dose 50 mg/day, 4 weeks on, 2 weeks off). The thyroid-stimulating hormone serum levels were obtained at the baseline and every 12 weeks of treatment. In statistic analyses, we used Kaplan-Meier method for assessment of progression-free survival; for comparison of survival, we used log-rank test. In our study, the incidence of hypothyroidism was 44%. The patients who had developed hypothyroidism had better median PFS to patients with normal thyroid function 28,3 months [95% (CI) 20.4-36.2 months] versus 9.8 months (6.4-13.1 months). In survival analysis, we perceive that thyroid dysfunction is a predictive factor of a progression-free survival (PFS). In the unified group of patients, the development of hypothyroidism during treatment with sunitinib is a positive marker for PFS. During that treatment, thyroid function should be evaluated regularly.

    The prognostic importance of patient pretreatment clinical and laboratory features was investigated in a group of 303 patients with Philadelphia chromosome-positive benign-phase chronic myelogenous leukemia. Intensive chemotherapy was given to 97 patients, and 78 underwent an early elective splenectomy. The overall median survival time, dated from hospital admission, was 39 months. Patient characteristics associated with shortened survival were age 60 years or older, black race, the presence of hepatomegaly, splenomegaly, symptoms, weight loss, and poor performance status. Adverse blood and bone marrow parameters were anemia, thrombocytosis or thrombocytopenia, a high proportion of peripheral blasts plus promyelocytes or of basophils, a high proportion of marrow blasts or basophils, decreased marrow megakaryocytes, and cytogenetic abnormalities in addition to the Philadelphia chromosome. Several of these factors were interrelated. A multivariate regression analysis demonstrated that the combination blood basophilia, race, additional cytogenetic abnormalities, age and marrow basophilia had the strongest predictive relationship to survival time. This resulted in a model segregating patients into low-, intermediate-, and high-risk groups, with median survivals of 53, 39, and 25 months, respectively. Another model was derived that did not include the marrow features and identified splenomegaly and platelet counts as adding to the prognosis prediction by blood basophilia, race, and age. Evaluation of the effect of therapy, after adjusting for differences in prognostic characteristics, showed that intensive chemotherapy was associated with survival prolongation among patients at intermediate and high risk of death. We conclude that a combination of pretreatment factors identifies different risk subcategories in patients with chronic myelogenous leukemia and is helpful in assessing overall prognosis and treatment effect.

    Drug survival has recently become an important clinical issue in psoriasis. However, there has been little research into factors associated with drug survival of methotrexate and acitretin. The aim of this study was to investigate factors associated with drug survival of methotrexate and acitretin treatment for psoriasis. Survival analysis was performed in patients who received methotrexate or acitretin for the treatment of psoriasis, drawn from the Clalit Health Services database. Investigated factors included demographic variables, obesity, metabolic syndrome, psoriatic arthritis, administration route and folic acid supplementation. Among 6,256 patients, factors associated with treatment drop-out were: younger age (p <0.001) and psoriatic arthritis (acitretin p < 0.001). For methotrexate, metabolic syndrome (p = 0.033), intramuscular administration route of injection (p <0.001) and lack of folic acid supplementation (p <0.001) were associated with treatment drop-out. In patients with psoriasis, some ancillary factors may modify the drug survival of acitretin and methotrexate.

    Development of effective therapies for recurrent glioblastoma multiforme (GBM) and reliable, timely evaluation of their benefit are needed. Understanding the relationship between objective response (OR) and survival is important for determining whether OR can provide an early signal of treatment activity in clinical trials. We performed a landmark analysis to evaluate the association between OR and survival at 9, 18, and 26 weeks for 167 patients with recurrent GBM who participated in BRAIN, a phase II trial that evaluated efficacy of bevacizumab alone or in combination with irinotecan, using the Cox regression models adjusted for age, baseline Karnofsky performance score, first vs second relapse, and treatment arm. Hazard ratios (HRs) and P-values for survival between responders and nonresponders were calculated. Additional analyses were performed to test robustness, validity, fit, and accuracy of the models. The relationships between progression-free survival (PFS) and survival and between OR and PFS were also explored. There were 55 responders and 112 nonresponders across the 2 treatment arms in BRAIN. OR status at 9, 18, and 26 weeks was a statistically significant predictor of survival (HR ≤ 0.52, P < .01). PFS was also a statistically significant predictor of survival at each landmark (HR ≤ 0.25, P < .0001). The association between OR and PFS was not statistically significant, likely due to inadequate statistical power for the analysis. Clarifying the relationship of OR and survival is important for determining whether OR can be a reliable predictor of the benefit of a therapeutic agent in patients with recurrent GBM. PMID:21084434

    Purpose: Patients with bone metastases have a widely varying survival. A reliable estimation of survival is needed for appropriate treatment strategies. Our goal was to assess the value of simple prognostic factors, namely, patient and tumor characteristics, Karnofsky performance status (KPS), and patient-reported scores of pain and quality of life, to predict survival in patients with painful bone metastases. Methods and Materials: In the Dutch Bone Metastasis Study, 1157 patients were treated with radiation therapy for painful bone metastases. At randomization, physicians determined the KPS; patients rated general health on a visual analogue scale (VAS-gh), valuation of life on a verbal rating scale (VRS-vl) and pain intensity. To assess the predictive value of the variables, we used multivariate Cox proportional hazard analyses and C-statistics for discriminative value. Of the final model, calibration was assessed. External validation was performed on a dataset of 934 patients who were treated with radiation therapy for vertebral metastases. Results: Patients had mainly breast (39%), prostate (23%), or lung cancer (25%). After a maximum of 142 weeks' follow-up, 74% of patients had died. The best predictive model included sex, primary tumor, visceral metastases, KPS, VAS-gh, and VRS-vl (C-statistic = 0.72, 95% CI = 0.70-0.74). A reduced model, with only KPS and primary tumor, showed comparable discriminative capacity (C-statistic = 0.71, 95% CI = 0.69-0.72). External validation showed a C-statistic of 0.72 (95% CI = 0.70-0.73). Calibration of the derivation and the validation dataset showed underestimation of survival. Conclusion: In predicting survival in patients with painful bone metastases, KPS combined with primary tumor was comparable to a more complex model. Considering the amount of variables in complex models and the additional burden on patients, the simple model is preferred for daily use. In addition, a risk table for survival is provided.

    Mantle cell lymphoma is a rare aggressive lymphoma derived from B cells, characterized by rapid progression and subsequent recurrence. It is considered to be an incurable disease, with exception of a certain group of patients treated with an autogenic stem cell transplantation. The mean survival time is three years, after applying the conventional regimen based on COP (cyclophosphamide, vincristine, prednisone) or CHOP chemotherapy (COP + doxorubicin). An addition of rituximab to CHOP regimen significantly prolongs progression-free survival. The present case reports ten years progression-free survival in a female patient with mantle cell lymphoma with baseline clinical stage IVB (MIPI 5), treated with nine courses of CHOP chemotherapy. Rituximab was added from 3 to 8 course. The complete clinical, radiological and histopathological response has been obtained.

    Current evidence on the association between smoking and colorectal cancer (CRC) prognosis after diagnosis is heterogeneous and few have investigated dose-response effects or outcomes other than overall survival. Therefore, the association of smoking status and intensity with several prognostic outcomes was evaluated in a large population-based cohort of CRC patients; 3,130 patients with incident CRC, diagnosed between 2003 and 2010, were interviewed on sociodemographic factors, smoking behavior, medication and comorbidities. Tumor characteristics were collected from medical records. Vital status, recurrence and cause of death were documented for a median follow-up time of 4.9 years. Using Cox proportional hazards regression, associations between smoking characteristics and overall, CRC-specific, non-CRC related, recurrence-free and disease-free survival were evaluated. Among stage I-III patients, being a smoker at diagnosis and smoking ≥15 cigarettes/day were associated with lower recurrence-free (adjusted hazard ratios (aHR): 1.29; 95% confidence interval (CI): 0.93-1.79 and aHR: 1.31; 95%-CI: 0.92-1.87) and disease-free survival (aHR: 1.26; 95%-CI: 0.95-1.67 and aHR: 1.29; 95%-CI: 0.94-1.77). Smoking was associated with decreased survival in stage I-III smokers with pack years ≥20 (Overall survival: aHR: 1.40; 95%-CI: 1.01-1.95), in colon cancer cases (Overall survival: aHR: 1.51; 95%-CI: 1.05-2.17) and men (Recurrence-free survival: aHR: 1.51; 95%-CI: 1.09-2.10; disease-free survival: aHR: 1.49; 95%-CI: 1.12-1.97), whereas no associations were seen among women, stage IV or rectal cancer patients. The observed patterns support the existence of adverse effects of smoking on CRC prognosis among nonmetastatic CRC patients. The potential to enhance prognosis of CRC patients by promotion of smoking cessation, embedded in tertiary prevention programs warrants careful evaluation in future investigations.

    This study evaluated volume stability after alveolar ridge contouring with free connective tissue grafts at implant placement in single-tooth gaps. A total of 52 single-tooth gaps with labial volume deficiencies in the maxilla (incisors, canines, and premolars) were consecutively treated with implants and concomitant free palatal connective tissue grafts in 46 patients between 2006 and 2009. Implants had to be covered with at least 2 mm peri-implant local bone after insertion. At implant placement, a free connective tissue graft from the palate was fixed inside a labial split-thickness flap to form an existing concave buccal alveolar ridge contour due to tissue volume deficiency into a convex shape. Standardized volumetric measurements of the labial alveolar contour using a template were evaluated before connective tissue grafting and at 2 weeks, 1 year, and 5 years after implantprosthetic incorporation. Tissue volume had increased significantly (P < .05) in all six reference points representing the outer alveolar soft tissue contour of the implant before connective tissue grafting to baseline (2 weeks after implant-prosthetic incorporation). Statistically, 50% of the reference points (P > .05) kept their volume from baseline to 1 year after prosthetic incorporation and from baseline to 5 years after prosthetic incorporation, respectively, whereas reference points located within the area of the implant sulcus showed a significant (P < .05) decrease in volume. Clinically, 5 years after prosthetic incorporation the originally concave buccal alveolar contour was still convex in all implants, leading to a continuous favorable anatomical shape and improved esthetic situation. Intraoral radiographs confirmed osseointegration and stable peri-implant parameters with a survival rate of 100% after a follow-up of approximately 5 years. Implant placement with concomitant free connective tissue grafting appears to be an appropriate long-term means to contour preexisting buccal

    Given the lack of clinical data to guide optimal dosing of vancomycin in critically ill patients with life-threatening infections, the objective was to characterise vancomycin pharmacodynamics in MRSA-associated septic shock. Cases were extracted from an observational, multicentre study in Canadian Intensive Care Units and included 35 adult patients with MRSA-associated septic shock who received vancomycin and had a measured serum concentration within the first 72 h of therapy. Univariate and multivariate analyses were used to assess variables predictive of in-hospital mortality. Patients who survived were significantly younger and had better renal function, lower probability of chronic obstructive pulmonary disease, higher probability of intravenous drug use, lower probability of healthcare-associated infection and lower APACHE II score. Survivors also received higher vancomycin doses and had higher serum troughs and AUC₂₄/MIC values. The survival rate was 2.5-fold greater in patients who had vancomycin troughs ≥15 mg/L [70.6% (12/17) vs. 27.8% (5/18); P=0.001]. Two significant AUC₂₄/MIC thresholds for survival, ≥451 (P=0.006) and ≥578 (P=0.012), were identified by CART analysis. Only younger age (P=0.028) and higher vancomycin AUC₂₄/MIC (P=0.045) were significant in multivariate analyses of survival. This study of vancomycin in critically ill patients supports the current recommendation for serum troughs of at least 15 mg/L and, in patients with septic shock, an AUC₂₄/MIC threshold higher than the conventional 400. Improved survival was observed with the attainment of these pharmacodynamic targets.

    Glioblastoma multiforme (GBM) is the most common and aggressive adult primary brain cancer, with <10% of patients surviving for more than 3 years. Demographic and clinical factors (e.g. age) and individual molecular biomarkers have been associated with prolonged survival in GBM patients. However, comprehensive systems-level analyses of molecular profiles associated with long-term survival (LTS) in GBM patients are still lacking. We present an integrative study of molecular data and clinical variables in these long-term survivors (LTSs, patients surviving >3 years) to identify biomarkers associated with prolonged survival, and to assess the possible similarity of molecular characteristics between LGG and LTS GBM. We analyzed the relationship between multivariable molecular data and LTS in GBM patients from the Cancer Genome Atlas (TCGA), including germline and somatic point mutation, gene expression, DNA methylation, copy number variation (CNV) and microRNA (miRNA) expression using logistic regression models. The molecular relationship between GBM LTS and LGG tumors was examined through cluster analysis. We identified 13, 94, 43, 29, and 1 significant predictors of LTS using Lasso logistic regression from the somatic point mutation, gene expression, DNA methylation, CNV, and miRNA expression data sets, respectively. Individually, DNA methylation provided the best prediction performance (AUC = 0.84). Combining multiple classes of molecular data into joint regression models did not improve prediction accuracy, but did identify additional genes that were not significantly predictive in individual models. PCA and clustering analyses showed that GBM LTS typically had gene expression profiles similar to non-LTS GBM. Furthermore, cluster analysis did not identify a close affinity between LTS GBM and LGG, nor did we find a significant association between LTS and secondary GBM. The absence of unique LTS profiles and the lack of similarity between LTS GBM and LGG, indicates

    To investigate longitudinal changes in the survival rate of patients with amyotrophic lateral sclerosis in Wakayama Prefecture, Japan, we made a retrospective hospital-based study of 454 patients diagnosed with motor neuron disease (MND) at Wakayama Medical University (WMU) Hospital between 1966 and 2005. Of the 454 patients, 240 who were born and who lived in Wakayama Prefecture were diagnosed with definite or probable ALS during this period, according to the El Escorial criteria. The clinical data of the 240 patients, including sex, birth date, birthplace, address, age at onset, initial symptoms, date when respiratory support was applied (tracheostomy, noninvasive positive pressure ventilation, or mandatory artificial ventilation), and date of death were reviewed retrospectively. The age at onset of patients who developed initial symptoms before 1990 was 53.4+/-10.6 (mean+/-S.D.) and that in 1990 or thereafter was 64.8+/-10.3, respectively, showing a significant difference (p<0.0001). Clinical duration was determined from onset to either date of death or initiation of respiratory support in this study. Survival rate was compared using the Kaplan-Meier method according to age at onset, sex, initial symptoms and year of onset. Mean age at onset shifted towards older age according to a later year of onset, due to the overwhelming senility rate in Wakayama Prefecture. Older onset patients had a significantly poorer survival rate than younger onset patients when it was compared based on 10-year age groups (log rank, p<0.0001). Male patients had a poorer survival rate than female patients (p<0.0001). ALS patients with bulbar palsy onset showed shorter clinical durations than those with lower leg onset (p<0.0071, Breslow-Gehan-Wilcoxon test). Patients over 70 years old more frequently showed bulbar palsy onset compared to those younger than 69 (p=0.003). In a comparison of year of onset before and after 1990, ALS patients after 1990 had characteristics of older age

    Despite substantial evidence regarding the benefits of combined use of inhaled corticosteroids and long-acting beta2-agonists in asthma, such evidence remains limited for chronic obstructive pulmonary disease (COPD). Observational data may provide an insight into the expected survival in clinical trials of fluticasone propionate (FP) and salmeterol in COPD. Newly physician-diagnosed COPD patients identified in primary care during 1990-1999 aged > or = 50 yrs, of both sexes and with regular prescriptions of respiratory drugs were identified in the UK General Practice Research Database. Three-year survival in 1,045 COPD patients treated with FP and salmeterol was compared with that in 3,620 COPD patients who regularly used other bronchodilators but not inhaled corticosteroids or long-acting beta2-agonists. Standard methods of survival analysis were used, including adjustment for possible confounders. Survival at year 3 was significantly greater in FP and/or salmeterol users (78.6%) than in the reference group (63.6%). After adjusting for confounders, the survival advantage observed was highest in combined users of FP and salmeterol (hazard ratio (HR) 0.48 (95% confidence interval 0.31-0.73)), followed by users of FP alone (HR 0.62 (0.45-0.85)) and regular users of salmeterol alone (HR 0.79 (0.58-1.07)) versus the reference group. Mortality decreased with increasing number of prescriptions of FP and/or salmeterol. In conclusion, regular use of fluticasone propionate alone or in combination with salmeterol is associated with increased survival of chronic obstructive pulmonary disease patients managed in primary care.

    Background It has been proved that hepatitis B virus (HBV) infection alters the metastatic pattern and affects survival in colorectal cancer (CRC) and hepatocellular carcinoma (HCC), while the influence of HBV infection on metastatic pattern and survival in patients with pancreatic cancer (PC) has not been investigated yet. Methods We conducted an investigation to evaluate the impact of HBV infection on metastatic pattern and overall survival in PC. We collected the data of 460 PC patients treated in our hospital from 1999 to 2010. Serum HBV markers were tested with enzyme-linked immunosorbent assay. The impact of HBV infection on metastatic pattern and overall survival was analyzed. Results We found that the incidence of synchronous liver metastasis was significantly higher in patients with HBsAg positive than those with HBsAg negative (46.0% vs 32.0%, P < 0.05), and higher in chronic HBV infection (CHB) group than both non HBV infection and resolved HBV infection group (61.1% vs 33.9%, P < 0.05, and 61.1% vs 28.7%, P < 0.05, respectively). What’s more, Kaplan-Meier analysis showed that CHB, resolved HBV infection and non HBV infection group had significant longer overall survival (OS) compared with inactive HBsAg carriers (IC) group (P=0.037, P=0.009, and P=0.019 respectively). But, in the multivariate analysis, only the CHB and non HBV infection group had significant better overall survival compared with IC group (P=0.010 and P=0.018 respectively). Conclusions Our study found that HBV infection increased synchronous liver metastasis rate, and HBV infection status was an independent prognostic factor in PC patients. PMID:24099678

    Background Oral squamous cell carcinoma is an important cause of death and morbidity wordwide and effective prognostic markers are still to be discovered. HIF1α protein is associated with hypoxia response and neovascularization, essential conditions for solid tumors survival. The relationship between HIF1α expression, tumor progression and treatment response in head and neck cancer is still poorly understood. Patients and Methods In this study, we investigated HIF1α expression by immunohistochemistry in tissue microarrays and its relationship with clinical findings, histopathological results and survival of 66 patients with squamous cell carcinoma of the lower mouth. Results Our results demonstrated that high HIF1α expression is associated with local disease-free survival, independently from the choice of treatment. Furthermore, high expression of HIF1α in patients treated with postoperative radiotherapy was associated with survival, therefore being a novel prognostic marker in squamous cell carcinoma of the mouth. Additionally, our results showed that MVD was associated with HIF1α expression and local disease relapse. Conclusion These findings suggest that HIF1α expression can be used as a prognostic marker and predictor of postoperative radiotherapy response, helping the oncologist choose the best treatment for each patient.

    Background The influence of lifestyle diseases on postoperative complications and long-term survival in patients with non-small cell lung cancer (NSCLC) is unclear. The aim of this study was to determine whether lifestyle diseases were significant risk factors of perioperative and long-term surgical outcomes in elderly patients with stage I NSCLC. Methods Between December 1995 and November 2013, 110 patients aged 65 years or older who underwent surgical resection of stage I NSCLC at Dong-A University Hospital were retrospectively studied. We assessed the presence of the following lifestyle diseases as risk factors for postoperative complications and long-term mortality: diabetes, hypertension, chronic obstructive pulmonary disease, stroke, and ischemic heart disease. Results The mean age of the patients was 71 years (range, 65 to 82 years). Forty-six patients (41.8%) had hypertension, making it the most common lifestyle disease, followed by diabetes (n=23, 20.9%). The in-hospital mortality rate was 0.9% (n=1). The 3-year and 5-year survival rates were 78% and 64%, respectively. Postoperative complications developed in 32 patients (29.1%), including 7 (6.4%) with prolonged air leakage, 6 (5.5%) with atrial fibrillation, 5 (4.5%) with delirium and atelectasis, and 3 (2.7%) with acute kidney injury and pneumonia. Univariate and multivariate analyses showed that the presence of a lifestyle disease was the only independent risk factor for postoperative complications. In survival analysis, univariate analysis showed that age, smoking, body mass index, extent of resection, and pathologic stage were associated with impaired survival. Multivariate analysis revealed that resection type (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.08 to 4.49; p=0.030) and pathologic stage (HR, 1.89; 95% CI, 1.02 to 3.49; p=0.043) had independent adverse impacts on survival. Conclusion This study demonstrated that the presence of a lifestyle disease was a significant prognostic

    Malignant pleural effusion (MPE) is common in most patients with advanced cancer, especially in those with lung cancer, metastatic breast carcinoma and lymphoma. This complication usually leads patients to suffer from significant dyspnea, which may impair their mobility and reduce their quality of life. In patients with MPE, several interventions have been shown to be useful for palliation of the symptoms, including talc pleurodesis. The aim of this study was to evaluate prognostic factors for survival of patients with symptomatic MPE who underwent palliative video-assisted thoracoscopic (VATS) talc pleurodesis. Thirty-five patients with MPE underwent VATS, evacuation of the pleural fluid and talc pleurodesis with large-particle talc. There were 22 (62.9%) males and 13 (37.1%) females, with an overall median age of 69 years (range 42-81 years). The main causes of MPE were non-small cell lung carcinoma, breast or ovarian cancer and malignant pleural mesothelioma. The age did not differ (p=0.88) between men (68.6±11.6 years) and women (68.0±8.7 years). The mean quantity of pleural effusion was 2005.7±1078.9 ml, while the overall survival was 11.2±8.9 months. We did not find any relationship between survival and gender (log-rank test, p=0.53) or underlying malignancy associated with MPE (p=0.89, 0.48 and 0.36 for secondary cancer, lung cancer and mesothelioma, respectively). Similarly, no correlation was found between survival and age of the patients (Cox's regression, p=0.44) or quantity of pleural effusion (p=0.88). Our results show that the prognosis of patients after talc pleurodesis is independent of age, gender, type of malignancy and amount of pleural effusion, thus, suggesting the utility of treating all patients with symptomatic MPE early.

    As a result of successful therapy with radiation, chemotherapy, or both, patients with lymphoma are living longer. The improved survival has led to an increased awareness of long term complications including second or subsequent malignancies. We have recently seen six cases of lung cancer--three adenocarcinomas, one squamous cell carcinoma, and two small cell carcinomas--among 655 patients with Hodgkin and non-Hodgkin lymphoma suggesting a possible association, although other carcinogenic or cocarcinogenic factors cannot be eliminated.

    Patients infected with human immunodeficiency virus (HIV) can present with 4 pathology types: drug-induced vasospasm (ergotism), arterial limb ischemia, critical limb ischemia, and aneurysm. Although these problems are common vascular problems, they result in increased morbidity and mortality in HIV-infected patients, especially aneurysm. Patients with these problems tend to be diagnosed with difficulty because of atypical symptoms and signs. Because of lack of data in treatment outcome literature, our report explores and provides information on HIV infection-related arteriopathy. There were 17 patients in our 5-year review. There was no death in patients except the aneurysm type. The survival of aneurysm patients was significantly lower than from other pathologies (P = .003). Our case series showed good short-term outcome, and patients were not at risk for less beneficial surgical procedures.

    We examined the effect of alemtuzumab and basiliximab induction therapy on patient survival and freedom from bronchiolitis obliterans syndrome (BOS) in double lung transplantation. The United Network for Organ Sharing database was reviewed for adult double lung transplant recipients from 2006 to 2013. The primary outcome was risk-adjusted all-cause mortality. Secondary outcomes included time to BOS. There were 6117 patients were identified, of whom 738 received alemtuzumab, 2804 received basiliximab, and 2575 received no induction. Alemtuzumab recipients had higher lung allocation scores compared with basiliximab and no-induction recipients (41.4 versus 37.9 versus 40.7, p < 0.001) and were more likely to require mechanical ventilation before to transplantation (21.7% versus 6.5% versus 6.2%, p < 0.001). Median survival was longer for alemtuzumab and basiliximab recipients compared with patients who received no induction (2321 versus 2352 versus 1967 days, p = 0.001). Alemtuzumab (hazard ratio 0.80, 95% confidence interval 0.67-0.95, p = 0.009) and basiliximab induction (0.88, 0.80-0.98, p = 0.015) were independently associated with survival on multivariate analysis. At 5 years, alemtuzumab recipients had a lower incidence of BOS (22.7% versus 55.4 versus 55.9%), and its use was independently associated with lower risk of developing BOS on multivariate analysis. While both induction therapies were associated with improved survival, patients who received alemtuzumab had greater median freedom from BOS.

    Available data correlating symptoms of colon cancer patients with the severity of the disease are very limited. In a population-based setting, we correlated information on symptoms of colon cancer patients with several pathological tumor parameters and survival. Information on all patients diagnosed with colon cancer in Iceland in 1995-2004 for this retrospective, population-based study was obtained from the Icelandic Cancer Registry. Information on symptoms of patients and blood hemoglobin was collected from patients' files. Pathological parameters were obtained from a previously performed standardized tumor review. A total of 768 patients entered this study; the median age was 73 years. Tumors in patients presenting at diagnosis with visible blood in stools were significantly more likely to be of lower grade, having pushing border, conspicuous peritumoral lymphocytic infiltration, and lower frequency of vessel invasion. Patients with abdominal pain and anemia were significantly more likely to have vessel invasion. Logistic regression showed that visible blood in stools was significantly associated with protecting pathological factors (OR range 0.38-0.83, p < 0.05). Tumors in patients presenting with abdominal pain were strongly associated with infiltrative margin and scarce peritumoral lymphocytic infiltration (OR = 1.95; 2.18 respectively, p < 0.05). Changes in bowel habits were strongly associated with vessel invasion (OR = 2.03, p < 0.05). Cox regression showed that blood in stools predicted survival (HR = 0.54). In conclusion, visible blood in stools correlates significantly with all the beneficial pathological parameters analyzed and with better survival of patients. Anemia, general symptoms, changes in bowel habits, acute symptoms, and abdominal pain correlate with more aggressive tumor characteristics and adverse outcome for patients.

    Malignant pleural effusions (MPE) are commonly managed with either pleural catheter (PC) or talc pleurodesis (TP). The aim of this study was to compare survival in MPE patients treated with either PC or TP. A retrospective review of our cancer center database was performed. Patients with metastatic cancer and MPE were analyzed. Demographic and clinical data were tabulated and compared. A total of 238 patients with MPE treated by either PC or TP were included. Of these, 79 patients comprised the PC group and 159 the TP group. PC had a higher incidence of advanced disease (stage III or IV) at initial diagnosis compared with TP (70.9% vs 57.2%, P = 0.05). TP had a longer postprocedure length of stay compared with PC (7.1 vs 5.0 days, P = 0.02); however, overall length of stay was similar (9.7 vs 11.1 days, P = 0.34). Readmissions were significantly lower in TP (11.9% vs 22.8%, P = 0.04). Mean survival was higher in TP compared with PC (18.7 vs 4.1 months, P < 0.001). Patients with metastatic cancer and MPE treated with TP had significantly higher survival compared with PC. This is likely related to a greater disease burden in PC, as 70 per cent of patients in this group had stage III or IV disease on initial presentation.

    In gastric cancer, primary systemic chemotherapy is the standard approach for the management of patients with initially unresectable metastasis, and it occasionally leads to a reduction in the size of the lesion, which facilitates surgical resection. The aim of this study was to examine the prognosis of patients who were able to undergo complete resection following chemotherapy. A total of 10 patients who underwent radical surgery for stage IV primary gastric cancer after chemotherapy between 2009 and 2015 at the Department of Surgery of Hokkaido Social Work Association Obihiro Hospital (Obihiro, Japan) were retrospectively investigated. Three regimens were used (S-1, n=1; S-1 + cisplatin, n=8; and S-1 + docetaxel, n=1). The mean time from chemotherapy to surgery was 210 days. One total gastrectomy + splenectomy + colectomy, one total gastrectomy + splenectomy, four total gastrectomies and three distal gastrectomies were performed. There were two cases of pancreatic fistula formation postoperatively. All the patients survived for >1 year. Of the 10 patients, 5 survived without recurrence. The median survival time was 871.1 days after diagnosis. Therefore, curative resection after chemotherapy is associated with a better prognosis in stage IV gastric cancer patients.

    Absolute Lymphocyte Count (ALC) has been recently established as a prognostic factor of survival in pediatric Acute Lymphoblastic Leukemia (ALL). A retrospective analysis of 132 patients treated according the BFM - ALLIC 2002 protocol was performed in a single institution. A possible association between ALC values and Overall Survival (OS) or Event-Free Survival (EFS) was evaluated at multiple time points during induction chemotherapy. ALC higher than 350 cells/μL measured on the 33th day of induction was associated with better Overall- and Event-Free Survival in both Kaplan-Meier (OS 88.6% vs. 40%; p < 0.001 / EFS 81.6% vs. 30%; p < 0.001) and Cox regression (OS HR 8.77 (3.31-23.28); p < 0.001) and EFS HR 6.61 (2.79-15.63); p < 0.001) analyses. There was no association between survival and measured ALC values from earlier time points (day of diagnosis, days 8 and 15) of induction therapy. Patients with low ALC values tend to have higher risk (MR or HR groups) and a higher age at diagnosis (>10 years). With help of day 33 ALC values of 350 cells/μL cutoff it was possible to refine day 33 flow cytometry (FC) Minimal Residual Disease (MRD) results within the negative cohort: higher ALC values were significantly associated with better survival. ALC on day 33 (350 cells/μL) remained prognostic for OS and EFS in multivariate analysis after adjusting it for age, cytogenetics, immunophenotype and FC MRD of induction day 33. According to these findings ALC on day 33 of induction is a strong predictor of survival in pediatric ALL.

Survival data were analyzed using Kaplan-Meier method and Cox proportional hazards model. Results The median survival period after diagnosis of bone metastasis was 22 weeks (5 months). The 26- and 52-week survival rates after bone metastasis were 36.5% and 15.4%, respectively. Cox regression analysis showed that extraskeletal metastasis (hazard ratio [HR], 6.1; 95% CI, 2.2 to 16.6), performance status of 3 to 4 (HR, 7.8; 95% CI, 3.3 to 18.2), previous radiation or chemotherapy (HR, 3.3; 95% CI, 1.4 to 7.8), multiple bone metastases (HR, 1.9; 95% CI, 1.0 to 3.5), and a bone metastasis-free interval of <12 months (HR, 2.5; 95% CI, 1.2 to 5.3) were significantly and independently related to poor survival. A prognostic score was calculated by adding the number of each significant factor. The 26-week survival rates after diagnosis of bone metastasis were 70.1% in the group with a score ≤2, 46.7% in the group with a score of 3, and 12.5% in the group with a score ≥4 (p<0.001). Conclusion This scoring system provided useful prognostic information on survival of patients with bone metastasis of cervical cancer. PMID:27550401

    The purpose of this study is to summarize the currently available evidence regarding the concerned issue by performing a comprehensive meta-analysis. Relevant publications reporting the association of metformin use with survival of lung cancer patients with diabetes were electronically searched to identify eligible studies. The meta-analysis was performed with hazard ratios (HRs) and 95% confidence intervals (95% CIs) as effect measures for disease-free survival(DFS) and overall survival(OS) estimates. A total of 17 individual studies from 10 publications were included in the meta-analysis. Overall, the results revealed a significant association of metformin use with a better survival of lung cancer patients with diabetes(for DFS: HR = 0.65, 95%CI = 0.52-0.83; for OS: HR = 0.78, 95%CI = 0.64-0.93). The subgroup analyses showed similar association in Asian region(for DFS:HR = 0.69, 95%CI = 0.59-0.80; for OS: HR = 0.55, 95%CI = 0.46-0.67) but not in Western region. Such association was also presented in small cell lung cancer (for DFS: HR = 0.54, 95%CI = 0.38-0.77; for OS: HR = 0.52, 95%CI = 0.39-0.69) and in non-small cell lung cancer(for DFS: HR = 0.70, 95%CI = 0.51-0.96; for OS: HR = 0.75, 95%CI = 0.58-0.97). Analyses stratified by treatment strategy showed a reduction in the risk of cancer-related mortality in patients receiving chemotherapy(for DFS: HR = 0.71, 95%CI = 0.64-0.83; for OS: HR = 0.58, 95%CI = 0.47-0.71) but not in patients receiving chemoradiotherapy. The meta-analysis demonstrated that metformin use was significantly associated with a favorable survival outcome of lung cancer patients with diabetes. PMID:27105507

    Influence of loneliness on human survival has been established epidemiologically, but genomic research remains undeveloped. We identified 34 loneliness-associated genes which were statistically significant for high- lonely and low-lonely individuals. With the univariate Cox proportional hazards regression model, we obtained corresponding regression coefficients for loneliness-associated genes fo individual cancer patients. Furthermore, risk scores could be generated with the combination of gene expression level multiplied by corresponding regression coefficients of loneliness-associated genes. We verified that high-risk score cancer patients had shorter mean survival time than their low-risk score counterparts. Then we validated the loneliness-associated gene signature in three independent brain cancer cohorts with Kaplan-Meier survival curves (n=77, 85 and 191), significantly separable by log-rank test with hazard ratios (HR) >1 and p-values <0.0001 (HR=2.94, 3.82, and 1.78). Moreover, we validated the loneliness-associated gene signature in bone cancer (HR=5.10, p-value=4.69e-3), lung cancer (HR=2.86, p-value=4.71e-5), ovarian cancer (HR=1.97, p-value=3.11e-5), and leukemia (HR=2.06, p-value=1.79e-4) cohorts. The last lymphoma cohort proved to have an HR=3.50, p-value=1.15e-7. Loneliness- associated genes had good survival prediction for cancer patients, especially bone cancer patients. Our study provided the first indication that expression of loneliness-associated genes are related to survival time of cancer patients.

    Concern has been expressed that calcium supplementation, a key intervention for preventing osteoporotic fracture in older women, may increase the risk of atherosclerotic vascular disease. To evaluate the risk further, an examination of complete verified atherosclerotic vascular hospitalization and mortality data from a 5-year randomized, controlled trial (RCT) of calcium carbonate and 4.5 years of posttrial follow-up was undertaken. This study used data from a published 5-year randomized, double-blinded, placebo-controlled trial [Calcium Intake Fracture Outcome Study (CAIFOS)]. The participants were 1460 women aged 75.1 ± 2.7 years at baseline (1998) recruited from the general population and randomized to receive 1200 mg of calcium carbonate daily or an identical placebo. All hospital admission and deaths during the 5-year study and the 4.5-year follow-up were derived from the Western Australian Data Linkage Service (WADLS). Hazard ratios (HRs) for the combined endpoint of atherosclerotic vascular mortality or first hospitalization were calculated using prespecified intention-to-treat and per-protocol models. The intervention group that received calcium supplementation did not have a higher risk of death or first-time hospitalization from atherosclerotic vascular disease in either the 5-year RCT [multivariate-adjusted HR = 0.938, 95% confidence interval (CI) 0.690-1.275] or during the 9.5 years of observational study (multivariate-adjusted HR = 0.919, 95% CI 0.737-1.146). Further analysis suggested that calcium supplementation may reduce the risk of hospitalization and mortality in patients with preexisting atherosclerotic cardiovascular disease. This trial provides compelling evidence that calcium supplementation of 1200 mg daily does not significantly increase the risk of atherosclerotic vascular disease in elderly women.

    Background Anecdotal reports suggesting that survival rates among hospitalized patients with Ebola virus disease in Guinea are higher than the 29.2% rate observed in the current epidemic in West Africa. Methods Survival after symptom onset was determined using Kaplan Meier survival methods among patients with confirmed Ebola virus disease treated in Conakry, Guinea from March 25, 2014, to August 5, 2014. We analyzed the relationship between survival and patient factors, including demographics and clinical features. Results Of the 70 patients analyzed [mean age ± standard deviation (SD), 34 ± 14.1; 44 were men], 42 were discharged alive with a survival rate among hospitalized patients of 60% (95% confidence interval, 41.5–78.5%). The survival rate was 28 (71.8%) among 39 patients under 34 years of age, and 14 (46.7%) among 30 patients aged 35 years or greater (p = 0.034). The rates of myalgia (3 of 42 versus 7 of 28, p = 0.036) and hiccups (1 of 42 versus 5 of 28, p = 0.023) were significantly lower among patients who survived. Conclusions Our results provide insights into a cohort of hospitalized patients with Ebola virus disease in whom survival is prominently higher than seen in other cohorts of hospitalized patients.

    Calcium supplements have been widely used by older men and women. However, in little more than a decade, authoritative recommendations have changed from encouraging the widespread use of calcium supplements to stating that they should not be used for primary prevention of fractures. This substantial shift in recommendations has occurred as a result of accumulated evidence of marginal antifracture efficacy, and important adverse effects from large randomized controlled trials of calcium or coadministered calcium and vitamin D supplements. In this review, we discuss this evidence, with a particular focus on increased cardiovascular risk with calcium supplements, which we first described 5 years ago. Calcium supplements with or without vitamin D marginally reduce total fractures but do not prevent hip fractures in community-dwelling individuals. They also cause kidney stones, acute gastrointestinal events, and increase the risk of myocardial infarction and stroke. Any benefit of calcium supplements on preventing fracture is outweighed by increased cardiovascular events. While there is little evidence to suggest that dietary calcium intake is associated with cardiovascular risk, there is also little evidence that it is associated with fracture risk. Therefore, for the majority of people, dietary calcium intake does not require close scrutiny. Because of the unfavorable risk/benefit profile, widespread prescribing of calcium supplements to prevent fractures should be abandoned. Patients at high risk of fracture should be encouraged to take agents with proven efficacy in preventing vertebral and nonvertebral fractures.

    Background A very small proportion of patients diagnosed with glioblastoma (GBM) survive more than 3 years. Isocitrate dehydrogenase 1 or 2 (IDH1/2) mutations define a small subgroup of GBM patients with favourable prognosis. However, it remains controversial whether long-term survivors (LTS) are found among those IDH1/2 mutated patients. Methods We retrospectively analyzed 207 GBM patients followed at Lariboisière Hospital (Paris) between 2005 and 2010. Clinical parameters were obtained from medical records. Mutations of IDH1/2 were analyzed in these patients, by immunohistochemistry for the R132H mutation of IDH1 and by high-resolution melting-curve analysis, followed by Sanger sequencing for IDH1 and IDH2 exon 4 mutations. Mutation rates in LTS and non-LTS groups were compared by Chi square Pearson test. Results Seventeen patients with survival >3 years were identified (8.2% of the total series). The median overall survival in long-term survivors was 4.6 years. Subgroup analysis found that the median age at diagnosis was significantly higher for non long-term survivors (non-LTS) compared to LTS (60 versus 51 years, p <0.03). The difference in the rate of IDH mutation between non-LTS and LTS was statistically not significant (1.16% versus 5.9%, p = 0.144). Among LTS, 10 out of 16 tumors presented a methylation of MGMT promoter. Conclusions This study confirms that long-term survival in GBM patients is if at all only weakly correlated to IDH-mutation.

    OBJECTIVES--To study the presentation and survival of patients who present with their first diagnosis of being HIV positive at the same time as their AIDS defining illness. DESIGN--Retrospective study of patients presenting with AIDS between 1991 and 1993. SETTING--Department of genitourinary medicine, St Mary's Hospital, London. MAIN OUTCOME MEASURES--AIDS defining illness at presentation and survival after diagnosis of AIDS. RESULTS--Between January 1991 and December 1993, 97 out of 436 patients (22%) presented with their first AIDS defining illness coincident with their first positive result of an HIV test (group B). The remaining 339 patients (78%) had tested positive for HIV-1 infection within the previous eight years and had consequently been followed up in clinics before developing their first AIDS defining illness (group A). The two groups of patients did not differ in age and sex distribution, risk factors for HIV-1 infection, nationality, country of origin, or haematological variables determined at the time of the AIDS defining illness. However, the defining illnesses differed between the two groups. Illnesses associated with severe immunodeficiency (the wasting syndrome, cryptosporidiosis, and cytomegalovirus infection) were seen almost exclusively in group A whereas extrapulmonary tuberculosis and Pneumocystis carinii pneumonia were more common in group B. The survival of patients in group B after the onset of AIDS was significantly longer than that of patients in group A as determined by Kaplan-Meier log rank analysis (P = 0.0026). CONCLUSIONS--Subjects who are HIV positive and present late are a challenge to the control of the spread of HIV infection because they progress from asymptomatic HIV infection to AIDS without receiving health care. The finding that presentation with an AIDS defining illness coincident with a positive result in an HIV test did not have a detrimental effect on survival gives insights into the effects of medical intervention on

    Background & objectives: The two key aspects associated with the microsatellite instability (MSI) as genetic phenomenon in colorectal cancer (CRC) are better survival prognosis, and the varying response to 5-fluorouracil (5-FU)-based chemotherapy. This study was undertaken to measure the survival of surgically treated patients with stages II and III CRC based on the MSI status, the postoperative 5-FU treatment as well as clinical and histological data. Methods: A total of 125 consecutive patients with stages II and III (American Joint Committee on Cancer, AJCC staging) primary CRCs, were followed prospectively for a median time of 31 months (January 2006 to December 2009). All patients were assessed, operated and clinically followed. Tumour samples were obtained for cytopathological verification and MSI grading. Results: Of the 125 patients, 21 (20%) had high MSI (MSI-H), and 101 patients (80%) had MSI-L or MSS (low frequency MSI or stable MSI). Patients with MSS CRC were more likely to have recurrent disease (P=0.03; OR=3.2; CI 95% 1-10.2) compared to those with MSI-H CRC. Multi- and univariate Cox regression analysis failed to show a difference between MSI-H and MSS groups with respect to disease-free, disease-specific and overall survival. However, the disease-free survival was significantly lower in patients with MSI-H CRC treated by adjuvant 5-FU therapy (P=0.03). Interpretation & conclusions: MSI-H CRCs had a lower recurrence rate, but the prognosis was worse following adjuvant 5-FU therapy. PMID:27748284

    Survival rates in kidney cancer have improved little over time, and diabetes may be an independent risk factor for poor survival in kidney cancer. We sought to determine whether medications with putative anti-neoplastic properties (statins, metformin and non-steroidal anti-inflammatory drugs (NSAIDs)) are associated with survival in diabetics with kidney cancer. We conducted a population-based cohort study utilizing linked healthcare databases in Ontario, Canada. Patients were aged 66 or older with newly diagnosed diabetes and a subsequent diagnosis of incident kidney cancer. Receipt of metformin, statins or NSAIDs was defined using prescription claims. The primary outcome was all-cause mortality and the secondary outcome was cancer-specific mortality. We used multivariable Cox proportional hazard regression, with medication use modeled with time-varying and cumulative exposure analyses to account for intermittent use. During the 14-year study period, we studied 613 patients. Current statin use was associated with a markedly reduced risk of death from any cause (adjusted hazard ratio 0.74; 95% CI 0.59-0.91) and death due to kidney cancer (adjusted hazard ratio 0.71; 95% CI 0.51-0.97). However, survival was not associated with current use of metformin or NSAIDs, or cumulative exposure to any of the medications studied. Among diabetic patients with kidney cancer, survival outcomes are associated with active statin use, rather than total cumulative use. These findings support the use of randomized trials to confirm whether diabetics with kidney cancer should be started on a statin at the time of cancer diagnosis to improve survival outcomes.

    S100P - low molecular weight acidic protein has been shown to be involved in processes of proliferation, survival, angiogenesis, multidrug resistance and metastasis in various human malignancies. In breast cancer, S100P expression is associated with immortalization of neoplastic cells and aggressive tumour behaviour, indicating that this protein may have adverse prognostic value. We analyzed nuclear and cytoplasmic expression of S100P in 85 stage II breast cancer patients with a median follow up of 17 years. Immunohistochemical reactions were performed on paraffin sections of primary tumours, using monoclonal antibodies against S100P. We also studied prognostic value of S100P mRNA expression using the KM plotter which assessed the effect of 22,277 genes on survival in 2422 breast cancer patients. Moreover, the relationship was examined between expression of S100P in cells of four breast cancer cell lines and their sensitivity to the 11 most frequently applied cytotoxic drugs. Univariate and multivariate analyses showed that higher expression of nuclear S100P (S100Pn) was typical for cases of a shorter overall survival and disease-free time. KM plotter analysis showed that elevated S100P expression was specific for cases of a relapse-free survival and distant metastases-free survival. No relationship could be documented between expression of S100P and sensitivity of breast cancer cells to cytostatic drugs. We demonstrated that a high S100Pn expression level was associated with poor survival in early stage breast cancer patients. Since preliminary data indicated that expression of S100P was up-regulated by activation of glucocorticoid receptor and several agents manifested potential to activate or inhibit S100P promoter activity, this protein might become a therapy target and warrants further studies with respect to its prognostic, predictive and potentially therapeutic value.

    Abstract Background: To understand whether the relationship between young children's autonomic nervous system (ANS) responses predicted their BMI, or vice versa, the association between standardized BMI (zBMI) at 2, 3.5, and 5 years of age and ANS reactivity at 3.5–5 years of age, and whether zBMI predicts later ANS reactivity or whether early ANS reactivity predicts later zBMI, was studied. Methods: Low-income, primarily Latino children (n=112) were part of a larger cohort study of mothers recruited during early pregnancy. Study measures included maternal prenatal weight, children's health behaviors (i.e., time watching television, fast food consumption, and time playing outdoors), children's height and weight at 2, 3.5, and 5 years, and children's ANS reactivity at 3.5 and 5 years. ANS measures of sympathetic nervous system (i.e., pre-ejection period) and parasympathetic nervous system (i.e., respiratory sinus arrhythmia) activity were monitored during rest and four challenges. Reactivity was calculated as the difference between mean challenge response and rest. Structural equation models analyzed the relationship between children's zBMI at 2, 3.5, and 5 years and ANS reactivity at 3.5 and 5 years, adjusting for mother's BMI, children's behaviors, and changes in height. Results: There was no association between zBMI and ANS cross-sectionally. Children with high zBMI at 2 or 3.5 years or large zBMI increases from 2 to 3.5 years of age had decreased sympathetic activity at 5 years. Neither sympathetic nor parasympathetic reactivity at 3.5 years predicted later zBMI. Conclusions: Increased zBMI early in childhood may dampen young children's SNS responses later in life.

    The major goal of this study was the identification of predictors for motor function and survival after irradiation alone for metastatic epidural spinal cord compression (MESCC) from melanoma. Ten variables (age, gender, performance status, number of involved vertebrae, pre-radiotherapy ambulatory status, further bone metastases, visceral metastases, interval from melanoma diagnosis to MESCC, time developing motor deficits before radiotherapy, fractionation regimen) were investigated for post-radiotherapy motor function, ambulatory status and survival in 27 patients. On multivariate analysis, motor function was significantly associated with time developing motor deficits (P = 0.006). On univariate analysis, post-radiotherapy ambulatory rates were associated with pre-radiotherapy ambulatory status (P < 0.001) and performance status (P = 0.046). Variables having a significant impact on survival in the univariate analysis were performance status (P < 0.001), number of involved vertebrae (P = 0.007), pre-radiotherapy ambulatory status (P = 0.020), further bone metastases (P = 0.023), visceral metastases (P < 0.001), and time developing motor deficits (P = 0.038). On multivariate analysis of survival, the Eastern Cooperative Oncology Group (ECOG) performance status (risk ratio [RR] = 4.35; 95% confidence interval [CI] = 1.04-16.67; P = 0.044) and visceral metastases (RR = 3.70; 95% CI = 1.10-12.50; P = 0.034) remained significant and were included in a survival score. Scoring points were obtained from 6-month survival rates divided by 10. Total scores represented the sum scores of both variables and were 3, 9 or 15 points. Six-month survival rates were 7%, 29% and 100% (P = 0.004). Thus, three predictors for functional outcomes were identified. The newly developed survival score included three prognostic groups. Patients with 3 points may receive 1 × 8 Gy, patients with 9 points 5 × 4 Gy and patients achieving 15 points longer

    Colorectal cancer is the third and the second most common cancer worldwide in men and women respectively, and the second in Malaysia for both genders. Surgery, chemotherapy and radiotherapy are among the options available for treatment of patients with colorectal cancer. In clinical trials, the main purpose is often to compare efficacy between experimental and control treatments. Treatment comparisons often involve several responses or endpoints, and this situation complicates the analysis. In the case of colorectal cancer, sets of responses concerned with survival times include: times from tumor removal until the first, the second and the third tumor recurrences, and time to death. For a patient, the time to recurrence is correlated to the overall survival. In this study, global score test methodology is used in combining the univariate score statistics for comparing treatments with respect to each survival endpoint into a single statistic. The data of tumor recurrence and overall survival of colorectal cancer patients are taken from a Malaysian hospital. The results are found to be similar to those computed using the established Wei, Lin and Weissfeld method. Key factors such as ethnic, gender, age and stage at diagnose are also reported.

    Under the auspices of an International Working Group, seven centers submitted diagnostic and follow-up information on 1545 patients with World Health Organization-defined polycythemia vera (PV). At diagnosis, median age was 61 years (51% females); thrombocytosis and venous thrombosis were more frequent in women and arterial thrombosis and abnormal karyotype in men. Considering patients from the center with the most mature follow-up information (n=337 with 44% of patients followed to death), median survival (14.1 years) was significantly worse than that of the age- and sex-matched US population (P<0.001). In multivariable analysis, survival for the entire study cohort (n=1545) was adversely affected by older age, leukocytosis, venous thrombosis and abnormal karyotype; a prognostic model that included the first three parameters delineated risk groups with median survivals of 10.9–27.8 years (hazard ratio (HR), 10.7; 95% confidence interval (CI): 7.7–15.0). Pruritus was identified as a favorable risk factor for survival. Cumulative hazard of leukemic transformation, with death as a competing risk, was 2.3% at 10 years and 5.5% at 15 years; risk factors included older age, abnormal karyotype and leukocytes ⩾15 × 109/l. Leukemic transformation was associated with treatment exposure to pipobroman or P32/chlorambucil. We found no association between leukemic transformation and hydroxyurea or busulfan use.

    Introduction. Diabetic population has a higher risk of colorectal cancer (CRC) incidence and mortality than nondiabetics. The role of metformin in CRC prognosis is still controversial. The meta-analysis aims to investigate whether metformin improves the survival of diabetic CRC patients. Methods. PubMed, EMBASE, and Cochrane Library were searched till July 1, 2016. Cohort studies were included. All articles were evaluated by Newcastle-Ottawa Scale. Hazard Ratios (HRs) with 95% confidence intervals (CIs) for each study were calculated and pooled HRs with corresponding 95% CIs were generated using the random-effects model. Heterogeneity and publication bias were assessed. Results. We included seven cohort studies with a medium heterogeneity (I2 = 56.1% and p = 0.033) in our meta-analysis. An improved overall survival (OS) for metformin users over nonusers among colorectal cancers with diabetes was noted (HR 0.75; 95% CI 0.65 to 0.87). However, metformin reveals no benefits for cancer-specific survival (HR 0.79, 95%, CI 0.58 to 1.08). Conclusions. Metformin prolongs the OS of diabetic CRC patients, but it does not affect the CRC-specific survival. Metformin may be a good choice in treating CRC patients with diabetes mellitus in clinical settings.

    Due to lack of sufficient data on characteristics of breast cancer patients and risk factors for developing metastasis in Iran this study was designed to understand clinical aspects impacting on survival. A cross-sectional study on breast cancer patients was conducted in an oncology clinic of the university hospital between 1995 and 2010. Data were retrieved from medical records and included age, menopausal status, tumor diameter, number of involved nodes, histopathological type, estrogen and progesterone receptor expression, c-erbB-2, primary and secondary metastasis sites, overall survival, disease free interval and type of chemotherapy protocol. The results were analyzed with SPSS 13 software.The mean age of the patients was 49.2 (27-89) years. The primary tumors were mainly ER positive (48%) and PR negative (49.3%). The status of lymph nodes dissected and examined in these patients was unknown in 19 patients (25.3%) while 18 patients (24%) had positive lymph nodes with no report on the number of involved nodes. All of the patients had received antracyclin based chemotherapy in an adjuvant or metastatic setting. Adjuvant hormonal therapy was administered to receptor positive patients. In average, overall survival after recurrence was 30 months (95%CI 24.605-35.325) for non-skeletal versus 42 months (95%CI 31.211-52.789) for skeletal metastasis (P= 0.002). The median survival was also greater for receptor positive patients; 39 months (95%CI 33.716-44.284) for PR+ versus 26 months (95%CI 19.210-32.790) for PR- (P=0.047) and 38 months (95%CI 32.908-43.092) for ER+ versus 27 months (95%CI 18.780-35.220) for ER- patients (P=0.016). No relation was found between site of first metastasis and hormone receptor, age, tumor diameter, DFI and menopausal status. Sites of metastasis were independent of age, size of the tumor, menopausal and hormone receptor status in this study. Overall survival provided significant relations with respect to receptor status and bone

    This study aimed to construct a prediction algorithm, which is readily applicable in the clinical setting, to determine the mortality rate for patients with P. aeruginosa bacteremia. A multicenter observational cohort study was performed retrospectively in seven university-affiliated hospitals in Korea from March 2012 to February 2015. In total, 264 adult patients with monomicrobial P. aeruginosa bacteremia were included in the analyses. Among the predictors independently associated with 30-day mortality in the Cox regression model, Pitt bacteremia score >2 and high-risk source of bacteremia were identified as critical nodes in the tree-structured survival analysis. Particularly, the empirical combination therapy was not associated with any survival benefit in the Cox regression model compared to the empirical monotherapy. This study suggests that determining the infection source and evaluating the clinical severity are critical to predict the clinical outcome in patients with P. aeruginosa bacteremia.

    Introduction. Omentin, a recently described adipokine, was shown to be involved in the pathophysiology of inflammatory and infectious diseases. However, its role in critical illness and sepsis is currently unknown. Materials and Methods. Omentin serum concentrations were measured in 117 ICU-patients (84 with septic and 33 with nonseptic disease etiology) admitted to the medical ICU. Results were compared with 50 healthy controls. Results. Omentin serum levels of critically ill patients at admission to the ICU or after 72 hours of ICU treatment were similar compared to healthy controls. Moreover, circulating omentin levels were independent of sepsis and etiology of critical illness. Notably, serum concentrations of omentin could not be linked to concentrations of inflammatory cytokines or routinely used sepsis markers. While serum levels of omentin were not predictive for short term survival during ICU treatment, low omentin concentrations were an independent predictor of patients' overall survival. Omentin levels strongly correlated with that of other adipokines (e.g., leptin receptor or adiponectin), which have also been identified as prognostic markers in critical illness. Conclusions. Although circulating omentin levels did not differ between ICU-patients and controls, elevated omentin levels were predictive for an impaired patients' long term survival. PMID:27867249

    Background Hemodialysis is the most common renal replacement therapy in patients with end stage renal disease (ESRD). Objectives The present study compared the performance of various parametric models in a survival analysis of hemodialysis patients. Methods This study consisted of 270 hemodialysis patients who were referred to Imam Khomeini and Fatima Zahra hospitals between November 2007 and November 2012. The Akaike information criterion (AIC) and residuals review were used to compare the performance of the parametric models. The computations were done using STATA Software, with significance accepted at a level of 0.05. Results The results of a multivariate analysis of the variables in the parametric models showed that the mean serum albumin and the clinic attended were the most important predictors in the survival of the hemodialysis patients (P < 0.05). Among the parametric models tested, the results indicated that the performance of the Weibull model was the highest. Conclusions Parametric models may provide complementary data for clinicians and researchers about how risks vary over time. The Weibull model seemed to show the best fit among the parametric models of the survival of hemodialysis patients. PMID:27896235

    The prognosis of renal cell carcinoma (RCC) with venous tumour thrombus (VTT) is variable and not always possible to predict. The prognostic impact and independence of tumour thrombus-related factors including the recently introduced tumour thrombus consistency (TTC) on overall survival remain controversial. The aim of this study was to investigate the prognostic role of TTC in patients' survival. We determined the tumour thrombus consistency (solid vs. friable) in a cohort of 84 patients with RCC and VTT who underwent nephrectomy with thrombectomy, and performed a retrospective evaluation of the patients' data from the prospectively maintained database. A total of 45% of patients had solid thrombus (sTT) and 55% had friable thrombus (fTT). The venous tumour thrombus consistency was not predictive of overall survival. Further studies, preferably prospective and with a larger number of patients, are needed to validate the obtained results, as well as to evaluate the usefulness of tumour thrombus consistency in clinical practice for stratifying the risk of recurrence and planning further follow-up.

    The effect of socioeconomic factors on receipt of definitive treatment and survival outcomes in non-metastatic head and neck squamous cell carcinoma (HNSCC) remains unclear. Eligible patients (n = 37,995) were identified from the United States Surveillance, Epidemiology and End Results (SEER) database between 2007 and 2012. Socioeconomic factors (i.e., median household income, education level, unemployment rate, insurance status, marital status and residence) were included in univariate/multivariate Cox regression analysis; validated factors were used to generate nomograms for cause-specific survival (CSS) and overall survival (OS), and a prognostic score model for risk stratification. Low- and high-risk groups were compared for all cancer subsites. Impact of race/ethnicity on survival was investigated in each risk group. Marital status, median household income and insurance status were included in the nomograms for CSS and OS, which had higher c-indexes than the 6th edition TNM staging system (all P-values < 0.001). Based on three disadvantageous socioeconomic factors (i.e., unmarried status, uninsured status, median household income < US $65,394), t
