    Summary Outcomes for melanoma patients with stage III disease differ widely even within the same subcategory. Molecular signatures that more accurately predict prognosis are needed to stratify patients according to risk. Proteomic analyses were used to identify differentially abundant proteins in extracts of surgically excised samples from patients with stage IIIc melanoma lymph node metastases. Analysis of samples from patients with poor (n = 14, <1 yr) and good (n = 19, >4 yr) survival outcomes identified 84 proteins that were differentially abundant between prognostic groups. Subsequent selected reaction monitoring analysis verified 21 proteins as potential biomarkers for survival. Poor prognosis patients are characterized by increased levels of proteins involved in protein metabolism, nucleic acid metabolism, angiogenesis, deregulation of cellular energetics and methylation processes, and decreased levels of proteins involved in apoptosis and immune response. These proteins are able to classify stage IIIc patients into prognostic subgroups (P < 0.02). This is the first report of potential prognostic markers from stage III melanoma using proteomic analyses. Validation of these protein markers in larger patient cohorts should define protein signatures that enable better stratification of stage III melanoma patients. PMID:24995518

    Like many cancers, an early diagnosis of melanoma is fundamental to ensure a good prognosis, although an important proportion of stage I-II patients may still develop metastasis during follow-up. The aim of this work was to discover serum biomarkers in patients diagnosed with primary melanoma that identify those at a high risk of developing metastasis during the follow-up period. Proteomic and mass spectrophotometry analysis was performed on serum obtained from patients who developed metastasis during the first years after surgery for primary tumors and compared with that from patients who remained disease-free for more than 10 years after surgery. Five proteins were selected for validation as prognostic factors in 348 melanoma patients and 100 controls by ELISA: serum amyloid A and clusterin; immune system proteins; the cell adhesion molecules plakoglobin and vitronectin and the antimicrobial protein dermcidin. Compared to healthy controls, melanoma patients have high serum levels of these proteins at the moment of melanoma diagnosis, although the specific values were not related to the histopathological stage of the tumors. However, an analysis based on classification together with multivariate statistics showed that tumor stage, vitronectin and dermcidin levels were associated with the metastatic progression of patients with early-stage melanoma. Although melanoma patients have increased serum dermcidin levels, the REPTree classifier showed that levels of dermcidin <2.98 μg/ml predict metastasis in AJCC stage II patients. These data suggest that vitronectin and dermcidin are potent biomarkers of prognosis, which may help to improve the personalized medical care of melanoma patients and their survival. PMID:27216146

    Background The seventh edition of the American Joint Committee on Cancer staging system (AJCC-7) includes significant changes for colon cancer (CC), which are particularly complex in patients with stage II and III disease. We used a national cancer database to determine if these changes improved prediction of survival. Study Design The database of the Surveillance, Epidemiology, and End Results (SEER) Program was queried to identify patients with pathologically confirmed stage I-III CC diagnosed between 1988 and 2008. CC was staged by sixth edition AJCC criteria (AJCC-6) and then restaged by AJCC-7. Five-year disease-specific survival (DSS) and overall survival (OS) were compared. Results After all exclusion criteria were applied, AJCC-6 and AJCC-7 staging was possible in 157,588 patients (68.9%). Bowker's test of symmetry showed that the number of patients per substage was different for AJCC-6 and AJCC-7 (p < 0.001). The Akaike information criteria comparison showed superior fit with the AJCC-7 model (p < 0.001). However, although AJCC-7 staging yielded a progressive decrease in DSS and OS of patients with stage IIA (86.3% and 72.4%, respectively), IIB (79.4% and 63.2%, respectively), and IIC (64.9% and 54.6%, respectively) disease, DSS and OS of patients with stage IIIA disease increased (89% and 79%, respectively). Subset analysis of patients with > 12 lymph nodes examined did not affect this observation. Conclusion AJCC-7 staging of CC does not address all survival discrepancies, regardless of the number of lymph nodes examined. Consideration of other prognostic factors is critical for decisions regarding therapy, particularly for patients with stage II CC. PMID:23768788

    We aimed to analyze the clinical characteristics and compare the surgical outcome of pancreatic neuroendocrine tumors (p-NETs) using the 2 tumor-node-metastasis (TNM) systems by both the American Joint Committee on Cancer (AJCC) Staging Manual (seventh edition) and the European Neuroendocrine Tumor Society (ENETS). Moreover, we sought to validate the prognostic value of the new AJCC criterion. Data of 145 consecutive patients who were all surgically treated and histologically diagnosed as p-NETs from January 2002 to June 2013 in our single institution were retrospectively collected and analyzed. The 5-year overall survival (OS) rates for AJCC classifications of stages I, II, III, and IV were 79.5%, 63.1%, 15.0%, and NA, respectively, (P < 0.005). As for the ENETS system, the OS rates at 5 years for stages I, II, III, and IV were 75.5%, 72.7%, 29.0%, and NA, respectively, (P < 0.005). Both criteria present no statistically notable difference between stage I and stage II (P > 0.05) but between stage I and stages III and IV (P < 0.05), as well as those between stage II and stages III and IV (P < 0.05). Difference between stage III and IV by ENETS was significant (P = 0.031), whereas that by the AJCC was not (P = 0.144). What's more, the AJCC Staging Manual (seventh edition) was statistically significant in both uni- and multivariate analyses by Cox regression (P < 0.005 and P = 0.025, respectively). Our study indicated that the ENETS TNM staging system might be superior to the AJCC Staging Manual (seventh edition) for the clinical practice of p-NETs. Together with tumor grade and radical resection, the new AJCC system was also validated to be an independent predictor for p-NETs. PMID:25816036

    Background Mucosal melanoma (MM) of head and neck (H &N) is a rare entity with a quite poor prognosis. Ballantyne’s staging system has been commonly used since 1970. In the 7th edition of the AJCC Staging Manual a new chapter for the staging of TNM Classification system for mucosal melanoma (MM) of the head and neck (H &N) has been introduced to reflect the particularly aggressive biological behavior of this neoplasm. The aim of this study was to analyze and compare among Ballantyne’s staging system vs TNM H &N in terms of overall survival (OS) and disease-free survival (DFS) in a consecutive population of patients with MM in a cancer centre. Material and Methods Descriptive analysis of demographic, clinical and pathological variables of MM of the Head & Neck were performed. We compared the survival curves for both systems according to the Kaplan-Meier method using the Log-rank test. Results An up-staging migration effect from Ballantyne’s localized disease to moderately and very advanced disease according to AJCC staging system. The 5-year DFS and OS for Ballantyne’s Localized Disease and AJCC Stage III were 31% and 36% vs. 47% and 50%, respectively. For locoregional disease the 5-year DFS / OS were 5% / 10% for Bal-lantyne’s system vs. 13.8% / 17.8% and 0 / 0% for AJCC Stages IVA and IVB, respectively. Conclusions In this series, the TNM staging system for MM of the H &N predicted better the prognosis of the disease when comparing with Ballantyne’s system. Key words:Head and neck, mucosal melanoma, AJCC TNM, Ballantynes´s staging system. PMID:27031071

    Purpose: To analyze the degree and pattern of influence of magnetic resonance imaging (MRI) on staging according to the 6th edition of the American Joint Committee on Cancer staging system compared with computed tomography (CT). Methods and Materials: The MRI and CT scans and medical records of 420 consecutive patients with newly diagnosed nasopharyngeal carcinoma (NPC) were analyzed retrospectively. The tumors of all patients were staged according to the 6th edition of the American Joint Committee on Cancer staging system. Results: A significant difference (p <0.05) was found between CT and MRI in demonstrating involvement in the oropharynx (CT, 25.0% vs. MRI, 14.5%), prevertebral muscle (CT, 18.4% vs. MRI, 36.0%), parapharyngeal space (CT, 82.6% vs. MRI, 68.8%), skull base (CT, 31.0% vs. MRI, 52.6%), sphenoid sinus (CT, 13.6% vs. MRI, 16.7%), ethmoid sinus (CT, 7.1% vs. MRI, 3.3%), intracranial area (CT, 4.8% vs. MRI, 16.0%), and retropharyngeal lymph nodes (CT, 52.1% vs. MRI, 69.0%). The incidence of cervical lymph node metastasis and lymph node metastasis at each level was similar according to CT and MRI. MRI resulted in changes in 49.8% of T stage cases, 10.7% of N stage cases, and 38.6% of clinical stage cases. Conclusion: MRI demonstrated early primary tumor involvement more precisely and deep primary tumor infiltration more easily. The use of MRI caused dramatic changes in the results of the T stage and clinical staging and should be preferred to CT in staging NPC. Patients would benefit from changes in treatment strategies resulting from the use of MRI.

    BACKGROUND An accurate staging system is crucial for cancer management. Evaluations for continual suitability and improvement are needed as staging and treatment methods evolve. METHODS This was a retrospective study of 1609 patients with nasopharyngeal carcinoma investigated by magnetic resonance imaging, staged with the 7th edition of the American Joint Committee on Cancer (AJCC)/International Union Against Cancer (UICC) staging system, and irradiated by intensity-modulated radiotherapy at 2 centers in Hong Kong and mainland China. RESULTS Among the patients without other T3/T4 involvement, there were no significant differences in overall survival (OS) between medial pterygoid muscle (MP)±lateral pterygoid muscle (LP), prevertebral muscle, and parapharyngeal space involvement. Patients with extensive soft tissue involvement beyond the aforementioned structures had poor OS similar to that of patients with intracranial extension and/or cranial nerve palsy. Only 2% of the patients had lymph nodes>6cm above the supraclavicular fossa (SCF), and their outcomes resembled the outcomes of those with low extension. Replacing SCF with the lower neck (extension below the caudal border of the cricoid cartilage) did not affect the hazard distinction between different N categories. With the proposed T and N categories, there were no significant differences in outcome between T4N0-2 and T1-4N3 disease. CONCLUSIONS After a review by AJCC/UICC preparatory committees, the changes recommended for the 8th edition include changing MP/LP involvement from T4 to T2, adding prevertebral muscle involvement as T2, replacing SCF with the lower neck and merging this with a maximum nodal diameter>6 cm as N3, and merging T4 and N3 as stage IVA criteria. These changes will lead not only to a better distinction of hazards between adjacent stages/categories but also to optimal balance in clinical practicability and global applicability. PMID:26588425

    Abstract We aimed to analyze the clinical characteristics and compare the surgical outcome of pancreatic neuroendocrine tumors (p-NETs) using the 2 tumor-node-metastasis (TNM) systems by both the American Joint Committee on Cancer (AJCC) Staging Manual (seventh edition) and the European Neuroendocrine Tumor Society (ENETS). Moreover, we sought to validate the prognostic value of the new AJCC criterion. Data of 145 consecutive patients who were all surgically treated and histologically diagnosed as p-NETs from January 2002 to June 2013 in our single institution were retrospectively collected and analyzed. The 5-year overall survival (OS) rates for AJCC classifications of stages I, II, III, and IV were 79.5%, 63.1%, 15.0%, and NA, respectively, (P < 0.005). As for the ENETS system, the OS rates at 5 years for stages I, II, III, and IV were 75.5%, 72.7%, 29.0%, and NA, respectively, (P < 0.005). Both criteria present no statistically notable difference between stage I and stage II (P > 0.05) but between stage I and stages III and IV (P < 0.05), as well as those between stage II and stages III and IV (P < 0.05). Difference between stage III and IV by ENETS was significant (P = 0.031), whereas that by the AJCC was not (P = 0.144). What's more, the AJCC Staging Manual (seventh edition) was statistically significant in both uni- and multivariate analyses by Cox regression (P < 0.005 and P = 0.025, respectively). Our study indicated that the ENETS TNM staging system might be superior to the AJCC Staging Manual (seventh edition) for the clinical practice of p-NETs. Together with tumor grade and radical resection, the new AJCC system was also validated to be an independent predictor for p-NETs. PMID:25816036

    Purpose: To use magnetic resonance imaging to re-evaluate and improve the 6th edition of the International Union Against Cancer/American Joint Committee on Cancer staging system for nasopharyngeal carcinoma. Methods and Materials: We performed a retrospective review of the data from 924 biopsy-proven nonmetastatic nasopharyngeal carcinoma cases. All patients had undergone magnetic resonance imaging examinations and received radiotherapy as their primary treatment. Results: The T classification, N classification, and stage group were independent predictors. No significant differences in the local failure hazards between adjacent T categories were observed between Stage T2b and T1, Stage T2b and T2a, and Stage T2b and T3. Although the disease failure hazards for Stage T1 were similar to those for Stage T2a, those for Stage T2b were similar to those for Stage T3. Survival curves of the different T/N subsets showed a better segregation when Stage T2a was downstaged to T1, T2b and T3 were incorporated into T2, and the nodal greatest dimension was rejected. The disease failure hazard for T3N0-N1 subsets were similar to those of the T1-T2N1 subsets belonging to Stage II; the same result was found for the T4N0-N2 subsets in the sixth American Joint Committee on Cancer staging system. However, the staging system we propose shows more consistent hazards within the same stage group and better survival discrimination among T categories, N categories, and overall stages. Conclusion: Using the 6th American Joint Committee on Cancer staging system produces an acceptable distribution of patient numbers and segregation of survival curves among the different stage groups. The prognostic accuracy of the staging system could be improved by recategorizing the T, N, and group stage criteria.

    Purpose: Prognostic factors can guide the physician in selecting the optimal treatment for an individual patient. This study investigates the prognostic value of erythropoietin (EPO) and EPO receptor (EPO-R) expression of tumor cells for locoregional control and survival in non-small-cell lung cancer (NSCLC) patients. Methods and Materials: Fourteen factors were investigated in 62 patients irradiated for stage II/III NSCLC, as follows: age, gender, Karnofsky performance score (KPS), histology, grading, TNM/American Joint Committee on Cancer (AJCC) stage, surgery, chemotherapy, pack years (average number of packages of cigarettes smoked per day multiplied by the number of years smoked), smoking during radiotherapy, hemoglobin levels during radiotherapy, EPO expression, and EPO-R expression. Additionally, patients with tumors expressing both EPO and EPO-R were compared to those expressing either EPO or EPO-R and to those expressing neither EPO nor EPO-R. Results: On univariate analysis, improved locoregional control was associated with AJCC stage II cancer (p < 0.048), surgery (p < 0.042), no smoking during radiotherapy (p = 0.024), and no EPO expression (p = 0.001). A trend was observed for a KPS of >70 (p = 0.08), an N stage of 0 to 1 (p = 0.07), and no EPO-R expression (p = 0.10). On multivariate analysis, AJCC stage II and no EPO expression remained significant. No smoking during radiotherapy was almost significant. On univariate analysis, improved survival was associated with N stage 0 to 1 (p = 0.009), surgery (p = 0.039), hemoglobin levels of {>=}12 g/d (p = 0.016), and no EPO expression (p = 0.001). On multivariate analysis, N stage 0 to 1 and no EPO expression maintained significance. Hemoglobin levels of {>=}12 g/d were almost significant. On subgroup analyses, patients with tumors expressing both EPO and EPO-R had worse outcomes than those expressing either EPO or EPO-R and those expressing neither EPO nor RPO-R. Conclusions: EPO expression of tumor cells

    Hemangiosarcomas (HSAs) are aggressive tumors with a high rate of metastasis. Clinical stage has been considered a negative prognostic factor for survival. The study authors hypothesized that the median survival time (MST) of dogs with metastatic (stage III) HSA treated with a vincristine, doxorubicin, and cyclophosphamide (VAC) chemotherapy protocol would not be different than those with stage I/II HSA. Sixty-seven dogs with HSA in different anatomic locations were evaluated retrospectively. All dogs received the VAC protocol as an adjuvant to surgery (n = 50), neoadjuvant (n = 3), or as the sole treatment modality (n = 14). There was no significant difference (P = 0.97) between the MST of dogs with stage III and stage I/II HSA. For dogs presenting with splenic HSA alone, there was no significant difference between the MST of dogs with stage III and stage I/II disease (P = 0.12). The overall response rate (complete response [CR] and partial response [PR]) was 86%). No unacceptable toxicities were observed. Dogs with stage III HSA treated with the VAC protocol have a similar prognosis to dogs with stage I/II HSA. Dogs with HSA and evidence of metastases at the time of diagnosis should not be denied treatment. PMID:24051260

    The melanoma staging system proposed by the American Joint Committee on Cancer (AJCC) (which classifies melanoma patients into four clinical stages) is currently the most widely used tool for melanoma prognostication, and clinical management decision making by clinicians. However, multiple studies have shown that melanomas within specific AJCC Stages can exhibit varying progression and clinical outcomes. Thus, additional information, such as that provided by biomarkers is needed to assist in identifying the patients at risk of disease progression. Having previously found six independent prognostic biomarkers in melanoma, including BRAF, MMP2, p27, Dicer, Fbw7 and Tip60, our group has gone on to investigate if these markers are useful in risk stratification of melanoma patients in individual AJCC stages. First, we performed Kaplan-Meier survival and Cox proportional multivariate analyses comparing prognostication power of these markers in 254 melanoma patients for whom the expression levels were known, identifying the best performing markers as candidates for stage-specific melanoma markers. We then verified the results by incorporating an additional independent cohort (87 patients) and in a combined cohort (341 patients). Our data indicate that BRAF and MMP2 are optimal prognostic biomarkers for AJCC Stages I and II, respectively (P = 0.010, 0.000, Log-rank test); whereas p27 emerged as a good marker for AJCC Stages III/IV (0.018, 0.046, respectively, log-rank test). Thus, our study has identified stage-specific biomarkers in melanoma, a finding which may assist clinicians in designing improved personalized therapeutic modalities. PMID:25784655

    Objectives/Hypothesis Document survival, prognostic variables, and functional outcomes of patients with AJCC stage III or IV oropharyngeal cancer, treated with transoral laser microsurgery (TLM) ± adjuvant therapy. Study Design Analysis of prospectively assembled data pertaining to the above-described patient cohort. Methods Patients treated with TLM for AJCC stage III or IV oropharyngeal cancer at Washington University School of Medicine from 1996 to 2006 were followed for a minimum of 2 years. Recurrence, survival, functional, and human papilloma virus data were analyzed. Results Eighty-four patients met inclusion criteria. Mean follow-up was 52.6 months. Overall AJCC stages were: III 15% and IV 85%. T stages were T1–2, 74%; T3–4, 26%. Eighty-three patients underwent neck dissection, 50 received adjuvant radiotherapy, and 28 received adjuvant chemoradiotherapy. Overall survival at 2 and 5 years was 94% and 88%, respectively. Disease-specific survival at 2 and 5 years was 96% and 92%, respectively. Six patients recurred (7%): locally (one), regionally (four), and distant (five). T stage, positive margins, and p16 status significantly impacted survival. The addition of adjuvant chemo-therapy in high-risk patients did not significantly impact survival. Five patients (6%) had major surgical complications, but without mortality. Eighty-one percent of patients had acceptable swallowing function at last follow-up. Immediately postoperatively, 17% required G-tubes, which dropped to 3.4% of living patients at 3 years. Conclusions In this population, our findings validate TLM ± adjuvant therapy as a highly effective strategy for survival, locoregional control, and swallowing recovery in AJCC stage III and IV oropharyngeal cancer. Our finding also show that p16 positivity improves survival. PMID:19572271

    Background The standard treatment for stage III non-small-cell lung cancer (NSCLC) is still 60 Gy in conventional fractions combined with concurrent chemotherapy; however, the resulting local controls are disappointing. The aim of this study was to compare and assess the feasibility and efficacy of hypofractionated chemoradiotherapy using helical tomotherapy (HT) with conventional fractionation as opposed to using three-dimensional conformal radiotherapy (3D-CRT) for stage III NSCLC. Methods Sixty-nine patients with stage III (AJCC 7th edition) NSCLC who underwent definitive radiation treatment at our institution between July 2011 and November 2013 were reviewed and analyzed retrospectively. A dose of 60 Gy in 20 fractions was delivered in the HT group (n=34), whereas 60 Gy in 30 fractions in the 3D-CRT group (n=35). Primary endpoints were toxicity, overall response rate, overall survival (OS) and progression-free survival (PFS). Results The median follow-up period was 26.4 months. V20 (P=0.005), V30 (P=0.001), V40 (P=0.004), mean lung dose (P=0.000) and max dose of spinal cord (P=0.005) were significantly lower in the HT group than in the 3D-CRT group. There was no significant difference in the incidences of acute radiation pneumonitis (RP) ≥ grade 2 between the two groups, whereas the incidences of acute radiation esophagitis ≥ grade 2 were significantly lower in the HT group than in the 3D-CRT group (P=0.027). Two-year overall response rate was significantly higher in the HT group than in the 3D-CRT group (P=0.015). One- and 2-year OS rates were significantly higher in the HT group (95.0% and 68.7%, respectively) than in the 3D-CRT group (85.5% and 47.6%, respectively; P=0.0236). One- and 2-year PFS rates were significantly higher in the HT group (57.8% and 26.3%, respectively) than in the 3D-CRT group (32.7% and 11.4%, respectively; P=0.0351). Univariate analysis indicated that performance status (PS), T stage and radiotherapy technique were significant

    Between 1986 and 1989 (4 years), 11 epithelial malignant tumours of the ovary were treated in the department of gynecology and obstetrics of the Libreville teaching hospital group. Epithelial tumours accounted for 78 per cent of malignant tumours in the adult. Burkitt's lymphoma predominated in young girls. Cancer of the ovary takes sixth place among female cancers in Gabon, with an incidence identical to that of cancer of the liver. Cases involved stage III and IV malignancies. Four patients died (36 per cent) and seven are still alive (63.6 per cent) with a mean survival of 25 months at the time of the study (the longest living patient having a survival of 5 years). The fullest possible initial surgical excision is essential in ensuring the greater efficacy of polychemotherapy (including Cisplatin), the only guarantee of total second look surgery. Monitoring of residual disease was based upon ultrasonography. Pelvic radiotherapy was used in the presence of a residual pelvic mass measuring less than 3 cm. Future efforts must be direct towards early detection, in particular since more than 45 per cent of our patients were aged under 30. PMID:1565942

  18. Comparison of outcomes in patients with stage III versus limited stage IV non-small cell lung cancer

    2011-01-01

    Background Standard therapy for metastatic non small cell lung cancer (NSCLC) includes palliative systemic chemotherapy and/or radiotherapy. Recent studies of patients with limited metastases treated with curative-intent stereotactic body radiation therapy (SBRT) have shown encouraging survival. We hypothesized that patients treated with SBRT for limited metastases have comparable outcomes with those treated with curative-intent radiation for Stage III NSCLC. Methods We retrospectively reviewed the records of NSCLC patients treated with curative-intent radiotherapy at the University of Rochester from 2000-2008. We identified 3 groups of patients with NSCLC: stage III, stage IV, and recurrent stage IV (initial stage I-II). All stage IV NSCLC patients treated with SBRT had ≤ 8 lesions. Results Of 146 patients, 88% had KPS ≥ 80%, 30% had > 5% weight loss, and 95% were smokers. The 5-year OS from date of NSCLC diagnosis for stage III, initial stage IV and recurrent stage IV was 7%, 14%, and 27% respectively. The 5-year OS from date of metastatic diagnosis was significantly (p < 0.00001) superior among those with limited metastases (≤ 8 lesions) versus stage III patients who developed extensive metastases not amenable to SBRT (14% vs. 0%). Conclusion Stage IV NSCLC is a heterogeneous patient population, with a selected cohort apparently faring better than Stage III patients. Though patients with limited metastases are favorably selected by virtue of more indolent disease and/or less bulky disease burden, perhaps staging these patients differently is appropriate for prognostic and treatment characterization. Aggressive local therapy may be indicated in these patients, though prospective clinical studies are needed. PMID:21718501

    We aimed to evaluate the functional abilities of persons with Rett syndrome (RTT) in stages III and IV. The group consisted of 60 females who had been diagnosed with RTT: 38 in stage III, mean age (years) of 9.14, with a standard deviation of 5.84 (minimum 2.2/maximum 26.4); and 22 in stage IV, mean age of 12.45, with a standard deviation of 6.17 (minimum 5.3/maximum 26.9). The evaluation was made using the Pediatric Evaluation of Disability Inventory, which has 197 items in the areas of self-care, mobility, and social function. The results showed that in the area of self-care, stage III and stage IV RTT persons had a level of 24.12 and 18.36 (P=0.002), respectively. In the area of mobility, stage III had 37.22 and stage IV had 14.64 (P<0.001), while in the area of social function, stage III had 17.72 and stage IV had 12.14 (P=0.016). In conclusion, although persons with stage III RTT have better functional abilities when compared with stage IV, the areas of mobility, self-care, and social function are quite affected, which shows a great functional dependency and need for help in basic activities of daily life.

    Background The identification of high-risk stage II colon cancers is key to the selection of patients who require adjuvant treatment after surgery. Microarray-based multigene-expression signatures derived from stem cells and progenitor cells hold promise, but they are difficult to use in clinical practice. Methods We used a new bioinformatics approach to search for biomarkers of colon epithelial differentiation across gene-expression arrays and then ranked candidate genes according to the availability of clinical-grade diagnostic assays. With the use of subgroup analysis involving independent and retrospective cohorts of patients with stage II or stage III colon cancer, the top candidate gene was tested for its association with disease-free survival and a benefit from adjuvant chemotherapy. Results The transcription factor CDX2 ranked first in our screening test. A group of 87 of 2115 tumor samples (4.1%) lacked CDX2 expression. In the discovery data set, which included 466 patients, the rate of 5-year disease-free survival was lower among the 32 patients (6.9%) with CDX2-negative colon cancers than among the 434 (93.1%) with CDX2-positive colon cancers (hazard ratio for disease recurrence, 3.44; 95% confidence interval [CI], 1.60 to 7.38; P=0.002). In the validation data set, which included 314 patients, the rate of 5-year disease-free survival was lower among the 38 patients (12.1%) with CDX2 protein-negative colon cancers than among the 276 (87.9%) with CDX2 protein-positive colon cancers (hazard ratio, 2.42; 95% CI, 1.36 to 4.29; P=0.003). In both these groups, these findings were independent of the patient's age, sex, and tumor stage and grade. Among patients with stage II cancer, the difference in 5-year disease-free survival was significant both in the discovery data set (49% among 15 patients with CDX2-negative tumors vs. 87% among 191 patients with CDX2-positive tumors, P=0.003) and in the validation data set (51% among 15 patients with CDX2-negative

    Purpose: To test the hypothesis that radiotherapy (RT) improves the outcome of patients with unresected, nonmetastatic bronchoalveolar carcinoma (BAC) by performing a population-based analysis within the Surveillance, Epidemiology, and End Results (SEER) registry. Methods and Materials: Inclusion criteria were as follows: patients diagnosed with BAC, Stage I-III, between 2001 and 2007. Exclusion criteria included unknown stage, unknown primary treatment modality, Stage IV disease, and those diagnosed at autopsy. Demographic data, treatment details, and overall survival were retrieved from the SEER database. Survival was analyzed using the Kaplan-Meier method and log-rank test. Results: A total of 6933 patients with Stage I-III BAC were included in the analysis. The median age at diagnosis was 70 years (range, 10-101 years). The majority of patients were diagnosed with Stage I (74.4%); 968 patients (14%) did not undergo surgical resection. Unresected patients were more likely to be older (p < 0.0001), male (p = 0.001), black (p < 0.0001), and Stage III (p < 0.0001). Within the cohort of unresected patients, 300 (31%) were treated with RT. The estimated 2-year overall survival for patients with unresected, nonmetastatic BAC was 58%, 44%, and 27% in Stage I, II, and III, respectively. Factors associated with improved survival included female sex, earlier stage at diagnosis, and use of RT. Median survival in those not receiving RT vs. receiving RT was as follows: Stage I, 28 months vs. 33 months (n = 364, p = 0.06); Stage II, 18 months vs. not reached (n = 31, nonsignificant); Stage III, 10 months vs. 17 months (n = 517, p < 0.003). Conclusions: The use of RT is associated with improved prognosis in unresected Stage I-III BAC. Less than a third of patients who could have potentially benefited from RT received it, suggesting that the medical specialists involved in the care of these patients underappreciate the importance of RT.

  5. Predictors of recurrence free survival for patients with stage II and III colon cancer

    2014-01-01

    Background The aim of this study was to evaluate clinico-pathologic specific predictors of recurrence for stage II/III disease. Improving recurrence prediction for resected stage II/III colon cancer patients could alter surveillance strategies, providing opportunities for more informed use of chemotherapy for high risk individuals. Methods 871 stage II and 265 stage III patients with colon cancers were included. Features studied included surgery date, age, gender, chemotherapy, tumor location, number of positive lymph nodes, tumor differentiation, and lymphovascular and perineural invasion. Time to recurrence was evaluated, using Cox’s proportional hazards models. The predictive ability of the multivariable models was evaluated using the concordance (c) index. Results For stage II cancer patients, estimated recurrence-free survival rates at one, three, five, and seven years following surgery were 98%, 92%, 90%, and 89%. Only T stage was significantly associated with recurrence. Estimated recurrence-free survival rates for stage III patients at one, three, five, and seven years following surgery were 94%, 78%, 70%, and 66%. Higher recurrence rates were seen in patients who didn’t receive chemotherapy (p = 0.023), with a higher number of positive nodes (p < 0.001). The c-index for the stage II model was 0.55 and 0.68 for stage III. Conclusions Current clinic-pathologic information is inadequate for prediction of colon cancer recurrence after resection for stage II and IIII patients. Identification and clinical use of molecular markers to identify the earlier stage II and III colon cancer patients at elevated risk of recurrence are needed to improve prognostication of early stage colon cancers.

    One hundred forty-seven patients with non-inflammatory, Stage III and IV breast cancer were treated with irradiation alone (54 patients) or with a combination of irradiation and mastectomy (93 patients). In the T/sub 3/ category, the local failure rate was 45% (5/11) for the irradiation alone patients vs 12% (3/25) for the irradiation plus surgery patients; in the T/sub 4/ category these figures were 65% (28/43) vs 13% (9/68), respectively. Corresponding local failure rates by size of primary tumor were 50% (2/4) vs 15% (5/29) for tumors 0-5 cm, 43% (0/21) vs 14% (6/45) for 5-8 cm tumors, and 75% (22/29) vs 5% (1/20) for tumors greater than or equal to8 cm. The rates of regional failure for the two treatment methods were compared according to N stage; they were 9% (2/23) for irradiation alone vs 11% (8/76) for irradiation plus surgery in the N/sub 0//sub -//sub 1/ category, and 58% (18/31) vs 18% (3/17), respectively, for the N/sub 2//sub -//sub 3/ category. A dose response analysis for patients with tumors greater than 5 cm treated with irradiation alone did not show a decrease in local failure rate with increasing total tumor dose over a range of 4000 to 7000 rad, suggesting that doses in this range are too low for these large tumors. Since a significant late complication rate has been reported with doses higher than this, patients with non-inflammatory, but large (>5 cm) tumors, should be treated with a combination of surgery and irradiation whenever possible to achieve maximum local-regional control with a minimum probability of complications. In 36 patients with inflammatory carcinoma, the rates of local and regional failure were 52% (15/29) and 38% (11/29), respectively, for patients treated with irradiation alone, and 14% (1/7) and 29% (2/7), respectively, for patients receiving irradiation plus surgery.

    Abstract The ability to stratify patients with pancreatic neuroendocrine tumors (p-NETs) into prognostic groups has been hindered by the absence of a commonly accepted staging system. Both the 7th tumor-node-metastasis (TNM) staging guidelines by the American Joint Committee on Cancer (AJCC) and the 2010 grading classifications by the World Health Organization (WHO) were validated to be unsatisfactory. We aim to evaluate the feasibility of combining the latest AJCC and WHO criteria to devise a novel tumor-grading-metastasis (TGM) staging system. We also sought to examine the stage-specific survival rates and the prognostic value of this new TGM system for p-NETs. Data of 120 patients with surgical resection and histopathological diagnosis of p-NETs from January 2004 to February 2014 in our institution were retrospectively collected and analyzed. Based on the AJCC and WHO criteria, we replaced the stage N0 and N1 with stage Ga (NET G1 and NET G2) and Gb (NET G3 and MANEC) respectively, without changes of the definition of T or M stage. The present novel TGM staging system was grouped as follows: stage I was defined as T1–2, Ga, M0; stage II as T3, Ga, M0 or as T1–3, Gb, M0; stage III as T4, Ga–b, M0 and stage IV as any T, M1. The new TGM staging system successfully distributed 55, 42, 12, and 11 eligible patients in stage I to IV, respectively. Differences of survival compared stage I with III and IV for patients with p-NETs were both statistically significant (P < 0.001), as well as those of stage II with III and IV (P < 0.001). Patients in stage I showed better a survival than those in stage II, whereas difference between stages III and IV was not notable (P = 0.001, P = 0.286, respectively). In multivariate models, when the TGM staging system was evaluated in place of the individual T, G, and M variables, this new criteria were proven to be an independent predictor of survival for surgically resected p-NETs (P < 0.05). Stratifying patients well

    Purpose The aim of this systematic review was to systematically assess the potential patient-relevant benefit (primary aim) and diagnostic and prognostic accuracy (secondary aim) of positron emission tomography (PET) and PET/computed tomography (CT) in primary staging of malignant melanoma. This systematic review updates the previous evidence for PET(/CT) in malignant melanoma. Materials and methods For the first aim, randomized controlled trials (RCTs) investigating patient-relevant outcomes and comparing PET and PET(/CT) with each other or with conventional imaging were considered. For the secondary aim, a review of reviews was conducted, which was amended by an update search for primary studies. MEDLINE, EMBASE and four databases of the Cochrane Library were searched. The risk of bias was assessed using a modified QUADAS tool. Results No RCTs investigating the patient-relevant benefit of PET(/CT) and no prognostic accuracy studies were found. Seventeen diagnostic accuracy studies of varying quality were identified. For patients with American Joint Committee on Cancer (AJCC) stages I and II, sensitivity mostly ranged from 0 to 67%. Specificity ranged from 77 to 100%. For AJCC stages III and IV, sensitivity ranged from 68 to 87% and specificity from 92 to 98%. Conclusion There is currently no evidence of a patient-relevant benefit of PET(/CT) in the primary staging of malignant melanoma. RCTs investigating patient-relevant outcomes are therefore required. The diagnostic accuracy of PET(/CT) appears to increase with higher AJCC stages. PMID:23237499

    Purpose: The present retrospective study assessed the role of proton beam therapy (PBT) in the treatment of patients with Stage II or III non-small-cell lung cancer who were inoperable or ineligible for chemotherapy because of co-existing disease or refusal. Patients and Methods: Between November 2001 and July 2008, PBT was given to 35 patients (5 patients with Stage II, 12 with Stage IIIA, and 18 with Stage IIIB) whose median age was 70.3 years (range, 47.4-85.4). The median proton dose given was 78.3 Gy (range, 67.1-91.3) (relative biologic effectiveness). Results: Local progression-free survival for Stage II-III patients was 93.3% at 1 year and 65.9% at 2 years during a median observation period of 16.9 months. Four patients (11.4%) developed local recurrence, 13 (37.1%) developed regional recurrence, and 7 (20.0%) developed distant metastases. The progression-free survival rate for Stage II-III patients was 59.6% at 1 year and 29.2% at 2 years. The overall survival rate of Stage II-III patients was 81.8% at 1 year and 58.9% at 2 years. Grade 3 or greater toxicity was not observed. A total of 15 patients (42.9%) developed Grade 1 and 6 (17.1%) Grade 2 toxicity. Conclusion: PBT for Stage II-III non-small-cell lung cancer without chemotherapy resulted in good local control and low toxicity. PBT has a definite role in the treatment of patients with Stage II-III non-small-cell lung cancer who are unsuitable for surgery or chemotherapy.

    Most lung cancer patients are diagnosed with a non-resectable disease; and around 40% in advanced stages. Stage III non-small cell lung cancer (NSCLC) is a heterogeneous disease with great variations in its clinical extent which presents a major therapeutic challenge. Although chemo-radiotherapy treatment has become the most widely used, there is currently no consensus on the best standard treatment and the experience of the therapy team plays an important role in the decision taking. We review the treatment of inoperable stage III NSCLC and the role of concomitant vinorelbine in this clinical scenario. PMID:22263088

    Background To assess and evaluate the prognostic value of the 7th edition of the Union for International Cancer Control–American Joint Committee on Cancer (UICC-AJCC) tumor, node, metastasis (TNM) staging system for Chinese patients with esophageal cancer in comparison with the 6th edition. Methods A retrospective review was performed on 766 consecutive esophageal cancer patients treated with esophagectomy between 2008 and 2012. Patients were staged according to the 6th and 7th editions for esophageal cancer respectively. Survival was calculated by the Kaplan-Meier method, and multivariate analysis was performed using Cox regression model. Results Overall 3-year survival rate was 59.5%. There were significant differences in 3-year survival rates among T stages both according to the 6th edition and the 7th edition (P<0.001). According to the 7th edition, the 3-year survival rates of N0 (75.4%), N1 (65.2%), N2 (39.7%) and N3 (27.3%) patients were significant differences (P<0.001). Kaplan-Meier curve revealed a good discriminatory ability from stage I to IV, except for stage IB, IIA and IIB in the 7th edition staging system. Based on the 7th edition, the degree of differentiation, tumor length and tumor location were not independent prognostic factors on multivariate analysis. The multivariate analyses suggested that pT-, pN-, pTNM-category were all the independent prognostic factors based on the 6th and 7th edition staging system. Conclusions The 7th edition of AJCC TNM staging system of esophageal cancer should discriminate pT2–3N0M0 (stage IB, IIA and IIB) better when considering the esophageal squamous cell cancer patients. Therefore, to improve and optimize the AJCC TNM classification for Chinese patients with esophageal cancer, more considerations about the value of tumor grade and tumor location in pT2–3N0M0 esophageal squamous cell cancer should be taken in the next new TNM staging system.

  16. A varying-stage adaptive phase II/III clinical trial design.

    Currently, adaptive phase II/III clinical trials are typically carried out with a strict two-stage design. The first stage is a learning stage called phase II, and the second stage is a confirmatory stage called phase III. Following phase II analysis, inefficacious or harmful dose arms are dropped, then one or two promising dose arms are selected for the second stage. However, there are often situations in which researchers are in dilemma to make 'go or no-go' decision and/or to select 'best' dose arm(s), as data from the first stage may not provide sufficient information for their decision making. In this case, it is challenging to follow a strict two-stage plan. Therefore, we propose a varying-stage adaptive phase II/III clinical trial design, in which we consider whether there is a need to have an intermediate stage to obtain more data, so that a more informative decision could be made. Hence, the number of further investigational stages in our design is determined on the basis of data accumulated to the interim analysis. With respect to adaptations, we consider dropping dose arm(s), switching another plausible endpoint as the primary study endpoint, re-estimating sample size, and early stopping for futility. We use an adaptive combination test to perform final analyses. By applying closed testing procedure, we control family-wise type I error rate at the nominal level of α in the strong sense. We delineate other essential design considerations including the threshold parameters and the proportion of alpha allocated in the two-stage versus three-stage setting. PMID:24273128

    Purpose: The purpose of this study was to analyze tumor heterogeneity based on tumor extent and suggest reappraisal of the system of the International Federation of Gynecology and Obstetrics (FIGO) for Stage III carcinoma of the uterine cervix from a radiotherapeutic viewpoint. Methods and Materials: Between 1986 and 2004, 407 patients with FIGO Stage III (FIGO Stage IIIa in 19 and IIIb in 388) were treated with external beam radiotherapy (RT) and high-dose rate brachytherapy. All patients were reviewed with respect to tumor extent. Patterns of failure and survival parameters were analyzed by use of the chi{sup 2} test and Kaplan-Meier method. Results: The complete response rate was 79.6%, and the 5-year overall survival rates for Stage IIIa and Stage IIIb carcinoma of the cervix were 82.1% and 54.8%, respectively. To determine which parameters of tumor extent had an influence on prognosis for Stage IIIb patients, pelvic wall (PW) extension and hydronephrosis (HD) retained significance on multivariate analysis. Stage IIIb patients were divided into three subgroups according to PW extension and HD: low risk (unilateral PW extension without HD), intermediate risk (HD without PW extension or bilateral PW extension without HD), and high risk (unilateral or bilateral PW extension with HD). The high-risk group had a remarkably low complete response rate, high locoregional failure rate, and low 5-year survival rate compared with the intermediate- and low-risk groups. Conclusions: FIGO Stage III carcinoma of the cervix covers considerably heterogeneous subgroups according to tumor extent. Before initiation of treatment, we suggest that physicians determine a tailored treatment policy based on tumor heterogeneity for each Stage III patient.

    Purpose: To determine whether time to treatment (TTT) has an effect on overall survival (OS) in patients with unresectable or medically inoperable Stage III non-small cell lung cancer (NSCLC) and whether patient or treatment factors are associated with TTT. Methods and Materials: Included in the study were 237 consecutive patients with Stage III NSCLC treated at University of Michigan Hospital (UM) or the Veterans Affairs Ann Arbor Healthcare System (VA). Patients were treated with either palliative or definitive radiotherapy and radiotherapy alone (n = 106) or either sequential (n = 69) or concurrent chemoradiation (n = 62). The primary endpoint was OS. Results: Median follow-up was 69 months, and median TTT was 57 days. On univariate analysis, the risk of death did not increase significantly with longer TTT (p = 0.093). However, subset analysis showed that there was a higher risk of death with longer TTT in patients who survived {>=} 5 years (p = 0.029). Younger age (p = 0.027), male sex (p = 0.013), lower Karnofsky Performance Score (KPS) (p = 0.002), and treatment at the VA (p = 0.001) were significantly associated with longer TTT. However, on multivariate analysis, only lower KPS remained significantly associated with longer TTT (p = 0.003). Conclusion: Time to treatment is significantly associated with OS in patients with Stage III NSCLC who lived longer than 5 years, although it is not a significant factor in Stage III patients as a whole. Lower KPS is associated with longer TTT.

    The ability to stratify patients with pancreatic neuroendocrine tumors (p-NETs) into prognostic groups has been hindered by the absence of a commonly accepted staging system. Both the 7th tumor-node-metastasis (TNM) staging guidelines by the American Joint Committee on Cancer (AJCC) and the 2010 grading classifications by the World Health Organization (WHO) were validated to be unsatisfactory.We aim to evaluate the feasibility of combining the latest AJCC and WHO criteria to devise a novel tumor-grading-metastasis (TGM) staging system. We also sought to examine the stage-specific survival rates and the prognostic value of this new TGM system for p-NETs.Data of 120 patients with surgical resection and histopathological diagnosis of p-NETs from January 2004 to February 2014 in our institution were retrospectively collected and analyzed. Based on the AJCC and WHO criteria, we replaced the stage N0 and N1 with stage Ga (NET G1 and NET G2) and Gb (NET G3 and MANEC) respectively, without changes of the definition of T or M stage. The present novel TGM staging system was grouped as follows: stage I was defined as T1-2, Ga, M0; stage II as T3, Ga, M0 or as T1-3, Gb, M0; stage III as T4, Ga-b, M0 and stage IV as any T, M1.The new TGM staging system successfully distributed 55, 42, 12, and 11 eligible patients in stage I to IV, respectively. Differences of survival compared stage I with III and IV for patients with p-NETs were both statistically significant (P < 0.001), as well as those of stage II with III and IV (P < 0.001). Patients in stage I showed better a survival than those in stage II, whereas difference between stages III and IV was not notable (P = 0.001, P = 0.286, respectively). In multivariate models, when the TGM staging system was evaluated in place of the individual T, G, and M variables, this new criteria were proven to be an independent predictor of survival for surgically resected p-NETs (P < 0.05).Stratifying patients well, the current

    Manganese superoxide dismutase (MnSOD) is a genetically engineered therapeutic DNA/liposome containing the human MnSOD transgene. Preclinical studies in mouse models have demonstrated that the expression of the human MnSOD transgene confers protection of normal tissues from ionizing irradiation damage. This is a phase I study of MnSOD plasmid liposome (PL) in combination with standard chemoradiation in surgically unresectable stage III non-small-cell lung cancer. Chemotherapy (carboplatin and paclitaxel) was given weekly (for 7 weeks), concurrently with radiation. MnSOD PL was swallowed twice a week (total 14 doses), at three dose levels: 0.3, 3, and 30 mg. Dose escalation followed a standard phase I design. Esophagoscopy was done at baseline, day 4, and 6 weeks after radiation with biopsies of the squamous lining cells. DNA was extracted and analyzed by PCR for the detection of the MnSOD transgene DNA. Ten patients with AJCC stage IIIA (three) and IIIB (seven) completed the course of therapy. Five had squamous histology, two adenocarcinoma, one large cell, and two not specified. Patients were treated in three cohorts at three dose levels of MnSOD PL: 0.3 (three patients), 3 (three patients), and 30 mg (four patients). The median dose of radiation was 77.7 Gy (range 63-79.10 Gy). Overall response rate for the standard chemoradiation regimen was 70% (n = 10). There were no dose-limiting toxicities reported in all three dosing tiers. It is concluded that the oral administration of MnSOD PL is feasible and safe. The phase II recommended dose is 30 mg.

    Abstract Adjuvant oxaliplatin-based chemotherapy is widely used for stage III colorectal cancer (CRC) after curative surgery. CRC is a molecularly heterogeneous disease, and our current knowledge of therapeutic response-related genetic factors remains limited. N-acetylgalactosaminyltransferase 14 (GALNT14)-rs9679162 genotype is a prognostic predictor for chemotherapy response in advanced hepatocellular carcinoma. Here, we investigated whether this genotype was related to the therapeutic outcome of stage III CRC. A cohort of 300 stage III CRC patients receiving curative resection followed by oxaliplatin-based chemotherapy was retrospectively recruited. GALNT14 genotypes and the clinicopathological factors were correlated with posttherapeutic prognosis. Of these patients, 18% patients had GALNT14-rs9679162 “TT” and 82% had the “GT” + “GG” genotypes. The analysis showed that the “TT” genotype was associated with unfavorable overall survival (OS, P = 0.009) but not with recurrence-free survival (RFS, P = 0.700). The subgroup analysis showed that the “TT” genotype was associated with unfavorable OS in the following subgroups: age ≤65 years, men, left side CRC, N2 stage, carcinoembryonic antigen >5 ng/mL, and mucinous histology (P = 0.012, 0.011, 0.009, 0.025, 0.013, and 0.007, respectively). Within the latter 2 subgroups, the “TT” genotype was the only independent predictor for OS. Finally, the “TT” genotype was associated with the T4 tumor stage (P = 0.017) and in patients with T4 tumors, the “TT” genotype was the only independent predictor for unfavorable RFS (P = 0.007). GALNT14 “TT” genotype was associated with unfavorable OS in stage III CRC patients receiving curative surgery and adjuvant oxaliplatin-based chemotherapy. PMID:27124048

    Purpose: The role of surgery in Stage III non-small-cell lung cancer (NSCLC) is controversial. This study was undertaken to assess the impact of neoadjuvant radiation therapy for Stage III NSCLC. Methods and Materials: This was a retrospective study from the Surveillance, Epidemiology, and End Results (SEER) database that included patients who were 18 years and older with NSCLC classified as Stage III and who underwent definitive therapy from 1988 to 2004. Patients were characterized by type of treatment received. Survival functions were estimated by the Kaplan-Meier method, and Cox regression model was used to analyze trends in overall (OS) and cause-specific survival (CSS). Results: A total of 48,131 patients were selected, with a median follow-up of 10 months (range, 0-203 months). By type of treatment, the 3-year OS was 10% with radiation therapy (RT), 37% with surgery (S), 34% with surgery and postoperative radiation (S-RT), and 45% with neoadjuvant radiation followed by surgery (Neo-RT) (p = 0.0001). Multivariable Cox model identified sex, race, laterality, T stage, N stage, and type of treatment as factors affecting survival. Estimated hazard ratios (HR) adjusted for other variables in regression model showed the types of treatment: S (HR, 1.3; 95% confidence interval [CI], 1.2-1.4), S-RT (HR, 1.2; 95% CI, 1.1-1.3), and RT (HR, 2.3; 95% CI, 2.15-2.53) were associated with significantly worse overall survival when compared with Neo-RT (p = 0.0001). Conclusion: This population based study demonstrates that patients with Stage III NSCLC receiving Neo-RT had significantly improved overall survival when compared with other treatment groups.

CCL21 expression dynamics were detected with western blotting. The expression of CCL21 in CRC tissue microarrays was examined by immunohistochemistry. The optimal cut-point of CCL21 expression was assessed by the X-tile program. The prognostic significance was analyzed using both Kaplan-Meier curves and Cox regression analysis. Western blot analysis demonstrated that CCL21 expression was comparable in the CRC and normal colorectal tissues. According to the X-tile program, the cut-point for high expression of CCL21 in CRC was determined when the CCL21 expression index was >56.1. Overexpression of CCL21 was significantly correlated with larger tumor diameter, more mucinous carcinoma or signet ring cell carcinoma and poor tumor differentiation. Patients with high expression of CCL21 had a higher overall survival rate in comparison to patients with low expression. In the multivariate Cox regression analysis, CCL21 expression was found to be an independent prognostic biomarker for CRC. ROC curves showed that CCL21 expression could improve the prognostic capability of TNM stage in stage III/IV CRC patients. High expression of CCL21 is an independent and useful biomarker for predicting longer survival of stage III/IV CRC patients. PMID:23760102

    Development of colorectal cancer (CRC) associates with accumulation of genetic mutations include the epidermal growth factor receptor (EGFR) signaling pathway. However, whether mutations in KRAS together with downstream factors BRAF, PIK3CA and NRAS impact prognosis is still unclear for stage II-III colon cancer. In the present study a total of 228 stage II-III colon cancer samples were retrospectively collected, KRAS (codons 12, 13 and 61), BRAF (exon 11 and exon 15), PIK3CA (exon 9 and exon 20) and NRAS (codons 12, 13 and 61) status was detected by Sanger sequencing, 37.89% (86/227) tumors harbored a KRAS mutation, 7.02% (16/228) harbored a BRAF mutation, 13.18% (29/220) harbored a PIK3CA mutation and 0.89% (2/224) harbored a NRAS mutation. NRAS mutations existed only in stage II colon cancer. Older groups harbored a higher KRAS and BRAF mutation (P < 0.05), PIK3CA (exon9) mutations appeared more common in worse differentiation tumors (P = 0.032). Moreover, PIK3CA (E545K) mutation was significantly associated with tumor recurrence (P = 0.031) and acted independently prognostic for poor OS (P = 0.044), while only in stage III colon cancer. KRAS, BRAF and NRAS mutations do not have major prognostic value in stage II and III colon cancer, subtypes of gene mutations should be further investigated for a better understanding in CRC.

    This paper presents a clinical and functional assessment of the cases of osteochondritis dissecans (OCD) treated with small mosaicplasty type osteochondral grafts. Between 1999 and 2004, we operated on 12 knees with OCD stages III and IV. They were assessed using the International Cartilage Research Society (ICRS) scale, the Visual Analogue Scale (VAS) scale, X-ray and magnetic resonance imaging (MRI). The study was carried out using a clinical series, was retrospective and had a level of evidence of 4. Before surgery, all patients were in classes III and IV on the ICRS scale (four in class III and eight in class IV). At the time of surgery, the patient age was 27.5 ± 7.9 years, with male predominance (75%). Eleven of the cases were assessed as classes I and II on the ICRS scale (seven in class I and four in class II), with one patient in class IV. X-ray assessment was less favourable, revealing alterations in the articular space in 75% of cases. The results show that this technique enables the biological fixation of fragments and, functionally, the clinical results obtained were very good. The osteochondral grafts avoid the implantation of foreign material and make use of bone fragments of the same rigidity as the OCD fragment. We conclude that the technique described is an excellent alternative to the techniques normally used for the fixation of stage III and IV OCD. PMID:18038231

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

    This study develops a geographical information system (GIS) approach for automated processing of the Next Generation Weather Radar (NEXRAD) Stage III precipitation data. The automated processing system, implemented by using commercial GIS and a number of Perl scripts and C/C++ programs, allows for rapid data display, requires less storage capacity, and provides the analytical and data visualization tools inherent in GIS as compared to traditional methods. In this paper, we illustrate the development of automatic techniques to preprocess raw NEXRAD Stage III data, transform the data to a GIS format, select regions of interest, and retrieve statistical rainfall analysis over user-defined spatial and temporal scales. Computational expense is reduced significantly using the GIS-based automated techniques. For example, 1-year Stage III data processing (˜9000 files) for the West Gulf River Forecast Center takes about 3 days of computation time instead of months of manual work. To illustrate the radar precipitation database and its visualization capabilities, we present three application examples: (1) GIS-based data visualization and integration, and ArcIMS-based web visualization and publication system, (2) a spatial-temporal analysis of monsoon rainfall patterns over the Rio Grande River Basin, and (3) the potential of GIS-based radar data for distributed watershed models. We conclude by discussing the potential applications of automated techniques for radar rainfall processing and its integration with GIS-based hydrologic information systems.

    Objectives To determine the combined effect of age and comorbidity on receipt of chemotherapy and its impact on survival in elderly patients with stage III colorectal cancer (CRC). Materials and methods All patients over age 65 with Stage III CRC diagnosed 1996–2006 were identified from the Barnes-Jewish Hospital Oncology Data Services registry. An age/comorbidity staging system was created using the ACE-27 comorbidity index and data from both Stage II and III CRC. The staging system was then applied to patients with Stage III CRC. Odds of receiving chemotherapy were calculated, and survival analyses determined the impact of chemotherapy on overall survival in each age/comorbidity stage. Results 435 patients with Stage III CRC were evaluated [median age 75 years (range 65–99)]. Advancing age/comorbidity stage (Alpha, Beta, Gamma) was associated with decreasing odds of receiving chemotherapy for Stage III CRC [Odds Ratio 0.83 (95% CI, 0.51–1.35) for Beta and 0.14 (95% CI, 0.08–0.24) for Gamma, compared to Alpha]. Chemotherapy was associated with lower risk of death in each of the age/comorbidity stages, compared to those who underwent surgery only. The hazard ratio for death in patients who did not receive chemotherapy, relative to those who did, within each age/comorbidity stage was 1.8 [95%CI 1.06–3.06] for Alpha, 2.24 [95%CI 1.38–3.63] for Beta and 2.10 [95% CI 1.23–3.57] for Gamma. Conclusion While stage III CRC patients with increasing age and comorbidity are less likely to receive chemotherapy, receipt of chemotherapy is associated with a lower risk of death. PMID:21113435

    Background We conducted a preliminary retrospective evaluation of the efficacy and toxicity of proton-beam therapy (pbt) for stage iii non-small-cell lung cancer. Methods Between January 2009 and August 2013, 27 patients (26 men, 1 woman) with stage iii non-small-cell lung cancer underwent pbt. The relative biologic effectiveness value of the proton beam was defined as 1.1. The beam energy and spread-out Bragg peak were fine-tuned such that the 90% isodose volume of the prescribed dose encompassed the planning target volume. Of the 27 patients, 11 underwent neoadjuvant chemotherapy. Cumulative survival curves were calculated using the Kaplan–Meier method. Treatment toxicities were evaluated using version 4 of the Common Terminology Criteria for Adverse Events. Results Median age of the patients was 72 years (range: 57–91 years), and median follow-up was 15.4 months (range: 7.8–36.9 months). Clinical stage was iiia in 14 patients (52%) and iiib in 13 (48%). The median dose of pbt was 77 GyE (range: 66–86.4 GyE). The overall survival rate in the cohort was 92.3% at 1 year and 51.1% at 2 years. Locoregional failure occurred in 7 patients, and distant metastasis, in 10. In 2 patients, initial failure was both locoregional and distant. The 1-year and 2-year rates of local control were 68.1% and 36.4% respectively. The 1-year and 2-year rates of progression-free survival were 39.9% and 21.4% respectively. Two patients experienced grade 3 pneumonitis. Conclusions For patients with stage iii non-small-cell lung cancer, pbt can be an effective and safe treatment option. PMID:26628878

    Background The aim of this study was to examine the specific chemoregimens selected for adjuvant therapy in the patients with stage III colon cancer. We investigated the trends in chemotherapeutic prescribing patterns and looked for adequate therapeutic setting for these patients. Methods 288 patients presenting with stage III colon cancer and undergoing adjuvant therapies after curative surgery for more than 3-month were enrolled between January 2006 and December 2011. Demographic characteristics and therapeutic factors were analyzed, including age, gender, histological grade, tumor sizes, tumor location, pathologic stage, performance status, serum carcinoembryonic antigen, regimens selection, interval from the operation to the start of adjuvant therapy and prolonged adjuvant therapy. Kaplan– Meier methods were utilized for drawing survival curves and Cox model was used to analyze survival, prognostic factors. Results The analysis showed that the patients aged under 70 received more intensive therapies than those aged over 70 (P<0.001). Later, advanced analysis in therapeutic factors was conducted between the patients aged under 70 and those over 70. In the patients aged under 70, significant differences in 4-year overall survival (OS) were noted between UFUR (oral tegafur-uracil plus leucovorin) groups and FOLFOX (5-FU plus oxaliplatin) [65.6% versus (vs) 89.8%, relative risk (RR) 3.780, 95% confidence interval (CI) 1.263–11.315, P = 0.017]. There were also differences in 4-year OS between these patients with and without oxaliplatin-contained regimens (92.1% vs 83.4%, respectively, RR 0.385, 95% CI 0.157–0.946, P = 0.037). In addition, the patients who received intravenous or combined therapy also had higher 4-year OS than those only received oral regimens (92.1% vs 76.6%, P = 0.077), though the finding did not reach statistical significance. In contrast to the survival benefits of above therapeutic settings for the patients aged under 70, there was less

    Purpose: To evaluate the effect of postmastectomy radiotherapy (PMRT) in Stage II-III breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy (NAC). Patients and Materials: Of 1,054 breast cancer patients treated with NAC at our institution between 1990 and 2004, 134 had pN0 status after NAC and mastectomy. The demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The effect of PMRT on locoregional recurrence-free survival and overall survival (OS) was evaluated by multivariate analysis, including known prognostic factors. Results: Of the 134 eligible patients, 78 (58.2%) received PMRT and 56 (41.8%) did not. At a median follow-up time of 91.4 months, the 5-year locoregional recurrence-free survival and OS rate was 96.2% and 88.3% with PMRT and 92.5% and 94.3% without PMRT, respectively (p = NS). The corresponding values at 10 years were 96.2% and 77.2% with PMRT and 86.8% and 87.7% without PMRT (p = NS). On multivariate analysis, PMRT had no effect on either locoregional recurrence-free survival (hazard ratio, 0.37; 95% confidence interval, 0.09-1.61; p = .18) or OS (hazard ratio, 2.06; 95% confidence interval, 0.71-6; p = .18). This remained true in the subgroups of patients with clinical Stage II or Stage III disease at diagnosis. A trend was seen toward poorer OS among patients who had not had a pathologic complete in-breast tumor response after NAC (hazard ratio, 6.65; 95% confidence interval, 0.82-54.12; p = .076). Conclusions: The results from the present retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence, or death when PMRT was omitted in breast cancer patients with pN0 status after NAC and mastectomy. Whether the omission of PMRT is acceptable for these patients should be addressed prospectively.

    In the National Comprehensive Cancer Network(NCCN)guidelines, oxaliplatin(L-OHP)-based chemotherapeutic regimens, including 5-fluorouracil, Leucovorin(LV), and L-OHP(FOLFOX); capecitabine and L-OHP(CapeOX); , and 5-fluorouracil, folinic acid, and L-OHP(FLOX)are designated as category 1 recommendations for postoperative adjuvant chemotherapy in Stage III colon cancer, followed by capecitabine and 5-fluorouracil plus LV as category 2A recommendations. We studied the selection of drugs for adjuvant chemotherapy and assessed the tolerability and safety of CapeOX and tegafur- uraci(l UFT)plus LV(UFT/LV)in patients with Stage III colon cancer. The study group included 104 consecutive patients with Stage III colon cancer who underwent curative surgery. One patient changed hospitals immediately after surgery. Among the remaining 103 patients, 82(80%)received adjuvant chemotherapy and 21(20%)did not. CapeOX was administered to 32 patients(31%), UFT/LV to 49 patients(48%), and capecitabine to 1 patient(1%). In 59 patients, the treatment choice was determined according to the patient's preference; 32 patient(s 54%)selected CapeOX, 26(44%)selected UFT/LV, and 1(2%) selected no chemotherapy. The treatment completion rate was 80% for CapeOX and 84% for UFT/LV. Among patients who completed chemotherapy, dose reduction and drug withdrawal were not required in 22% of patients who received CapeOX and 80% of those who received UFT/LV. Neither CapeOX nor UFT/LV was associated with any serious adverse events. The tolerability and safety of CapeOX and UFT/LV were acceptable. However, CapeOX dose had to be carefully adjusted according to each patient's condition. PMID:27210088

    2014-01-01

    Background Standard therapy for patients with stage I-III squamous cell carcinoma (SCC) of the anal canal is chemo-radiotherapy with 5-fluorouracil (5-FU) and mitomycin C (MMC). While there is limited published evidence to substitute capecitabine (CAP) for 5-FU, the objectives of the study were to describe the toxicity, dose intensity and outcomes of a sequential cohort of patients treated with chemo-radiotherapy with CAP and MCC in a population-based setting. Methods Patients with stage I-III malignancies of the anal canal referred between February 2010 and March 2012 were included. Dose intensity was calculated by comparing delivered versus planned radiation and chemotherapy treatments and toxicity was retrospectively graded according to standard protocol-specified criteria. Results Among 66 eligible patients, median planned dose of radiation was 51.9 Gy over 5.5 weeks, range 25.0 to 63 Gy, and dose intensity was 98%. Median delivered dose of MCC delivered was 12 mg/m2 on day one, week one while median CAP dose was 825 mg/m2 twice daily on radiation days. CAP dose reductions due to toxicity were recorded for 13 patients (20%). Median follow-up was 20 months and 94% of patients with squamous cell histology had no evidence of relapse. Conclusions Chemo-radiation with CAP plus MMC is well tolerated and may be a reasonable consideration for patients with stage I-III SCC of the anal canal. A range of planned radiation dose was observed and longer follow-up is necessary to ensure that patients who received lower doses of radiation have similar outcomes to those who received larger doses.

    Objective To explore if the addition of adjuvant chemotherapy with paclitaxel and carboplatin to radiotherapy confers an advantage for overall survival (OAS), and progression free survival (PFS); to assess the incidence of relapses over standard pelvic radiotherapy; and to evaluate the related toxicity in high-risk stage I-II endometrial carcinoma Methods Medical records were reviewed to identify high-risk stage I-II endometrial carcinoma cases treated in the Clinical Oncology and Nuclear Medicine department between 2002 and 2008 with adjuvant radiotherapy alone (arm I) (57 patients) or with sequential carboplatin (AUC5-6) and paclitaxel (135−175 mg/m2) with radiotherapy (arm II) (51 patients). Radiotherapy was performed through the four-field box technique at doses of 45−50 Gy (1.8 Gy/day × 5 days/week). Results The toxicity was manageable and predominantly hematologic with a grade 3 neutropenia and thrombocytopenia in 9.8% and 6% of the patients in arm I and arm II, respectively, without febrile neutropenia. All patients experienced hair loss. Chemoradiotherapy arm was associated with a lower incidence rate of relapse (9.8% vs. 22.7%). After a median follow-up period of 48 months, the 5-year OAS and PFS rates for chemoradiotherapy-treated patients were significantly more favorable than those who did not receive chemotherapy (P=0.02 and 0.03, respectively). In arm I, the OAS and PFS rates were 73.7% and 66.7% compared with those in arm II, whose rates were 90.2% and 84.3%. Conclusions Adjuvant chemoradiation with paclitaxel and carboplatin improved the survival rates and decreased the recurrence rates in patients with high-risk stage I-II endometrial carcinoma. Chemotherapy was associated with an acceptable rate of toxicity. However, a prospective study with a larger number of patients is needed to define a standard adjuvant treatment for high-risk stage I-II endometrial carcinoma. PMID:23691474

    Eleven patients with advanced stage III ovarian epithelial carcinoma were treated primarily according to an aggressive multimodality plan utilizing cytoreductive surgery, chemotherapy (high-dose cisplatin and Cytoxan), and consolidative radiation therapy (abdominopelvic bath plus pelvic boost). The treatment was tolerated remarkably well. There was no evidence of progressive disease during treatment, and all patients showed a positive response. There was a notable lack of significant acute morbidity, with the exception of a severe symptomatic peripheral neuropathy associated with cisplatin doses of 200 mg/m2. This was not evident with doses of cisplatin up to 150 mg/m2.

    Based on the suboptimal research pathways that finally led to multicenter randomized clinical trials (MRCTs) of treadmill training with partial body weight support and of robotic assistive devices, strategically planned successive stages are proposed for pilot studies of novel rehabilitation interventions Stage 1, consideration-of-concept studies, drawn from animal experiments, theories, and observations, delineate the experimental intervention in a small convenience sample of participants, so the results must be interpreted with caution. Stage 2, development-of-concept pilots, should optimize the components of the intervention, settle on most appropriate outcome measures, and examine dose-response effects. A well-designed study that reveals no efficacy should be published to counterweight the confirmation bias of positive trials. Stage 3, demonstration-of-concept pilots, can build out from what has been learned to test at least 15 participants in each arm, using random assignment and blinded outcome measures. A control group should receive an active practice intervention aimed at the same primary outcome. A third arm could receive a substantially larger dose of the experimental therapy or a combinational intervention. If only 1 site performed this trial, a different investigative group should aim to reproduce positive outcomes based on the optimal dose of motor training. Stage 3 studies ought to suggest an effect size of 0.4 or higher, so that approximately 50 participants in each arm will be the number required to test for efficacy in a stage 4, proof-of-concept MRCT. By developing a consensus around acceptable and necessary practices for each stage, similar to CONSORT recommendations for the publication of phase III clinical trials, better quality pilot studies may move quickly into better designed and more successful MRCTs of experimental interventions.

    This paper reports the 5-year results of a prospective randomized study beginning in 1976 on 177 evaluable patients with pathologic Stage I-IE and II-IIE non-Hodgkin's lymphomas with diffuse histology according to the Rappaport classification. Treatment consisted of either CVP or BACOP chemotherapy (3 cycles) followed by regional radiotherapy (40 to 50 Gy) and further cycles of either combination. In both arms, complete remission at the end of combined treatment was high (CVP 93%, BACOP 98%) regardless of age, stage or bulky disease. At 5 years, the comparative freedom from first progression was 62% for CVP vs 78% for BACOP (p = 0.02), respectively. Clinically relevant differences favoring BACOP chemotherapy were essentially documented in patients with large cell lymphomas (International Working Formulation), those with Stage II having more than three involved anatomical sites, bulky disease and age over 60 years. Recurrence within radiation fields was documented in only 5% of complete responders. Combined treatment was, in general, well tolerated particularly when BACOP was used. In only 2 patients given CVP post radiation cutaneous fibrosis was documented. Second solid tumors were detected in 4 patients. One patient started on CVP died because of brain stem necrosis after 45 Gy. We conclude that in Stage I-II patients with nodal and extranodal diffuse non-Hodgkin's lymphomas, particularly large cell lymphomas, combined modality approach with primary Adriamycin and bleomycin containing regimen, such as BACOP, followed by adjuvant radiotherapy offers high chances of cure with minimal toxicity.

    Stereotactic body radiotherapy (SBRT) is the precise external delivery of very high-dose radiotherapy to targets in the body, with treatment completed in one to five fractions. SBRT should be an ideal approach for organ-confined prostate cancer because (I) dose-escalation should yield improved rates of cancer control; (II) the unique radiobiology of prostate cancer favors hypofractionation; and (III) the conformal nature of SBRT minimizes high-dose radiation delivery to immediately adjacent organs, potentially reducing complications. This approach is also more convenient for patients, and is cheaper than intensity-modulated radiotherapy (IMRT). Several external beam platforms are capable of delivering SBRT for early-stage prostate cancer, although most of the mature reported series have employed a robotic non-coplanar platform (i.e., CyberKnife). Several large studies report 5-year biochemical relapse rates which compare favorably to IMRT. Rates of late GU toxicity are similar to those seen with IMRT, and rates of late rectal toxicity may be less than with IMRT and low-dose rate brachytherapy. Patient-reported quality of life (QOL) outcomes appear similar to IMRT in the urinary domain. Bowel QOL may be less adversely affected by SBRT than with other radiation modalities. After 5 years of follow-up, SBRT delivered on a robotic platform is yielding outcomes at least as favorable as IMRT, and may be considered appropriate therapy for stage I-II prostate cancer.

    Stage III metastatic melanomas require adequate adjuvant immunotherapy to prevent relapses. Prognostic factors are awaited to optimize the clinical management of these patients. The magnitude of metastatic lymph node invasion and the BRAF(V600) activating mutation have clinical significance. Based on a comprehensive immunophenotyping of 252 parameters per patient in paired blood and metastatic lymph nodes performed in 39 metastatic melanomas, we found that blood markers were as contributive as tumor-infiltrated lymphocyte immunotypes, and parameters associated with lymphocyte exhaustion/suppression showed higher clinical significance than those related to activation or lineage. High frequencies of CD45RA(+)CD4(+) and CD3(-)CD56(-) tumor-infiltrated lymphocytes appear to be independent prognostic factors of short progression-free survival. High NKG2D expression on CD8(+)tumor-infiltrated lymphocytes, low level of regulatory T-cell tumor-infiltrated lymphocytes, and low PD-L1 expression on circulating T cells were retained in the multivariate Cox analysis model to predict prolonged overall survival. Prospective studies are needed to determine whether such immunological markers may guide adjuvant therapies in stage III metastatic melanomas. PMID:26829031

    Background and Objectives: The precise role and potential underlying mechanisms of anoctamin 9 (ANO9) remain largely unknown. This study aims to characterize the role and oncogenic mechanisms of ANO9 in stage II and III colorectal cancer (CRC). Methods: We examined the expression of ANO9 in colorectal cancerous tissues and cells using real-time quantitative PCR and immunohistochemistry, respectively. Multiple cellular and molecular approaches such as gene transfection, CCK-8 assay, flow cytometry, and invasion assay were also performed to explore its oncogenic mechanisms. Furthermore, the clinical significance of ANO9 in clinical CRC specimens was assessed by clinical correlation and survival analyses. Results: Lower expression of ANO9 messenger RNA (mRNA) was frequently detected both in CRC tissues with recurrence and metastasis-derived cell lines. Compared with matched nontumorous tissues, lower expression of ANO9 protein was observed in tumors, which was significantly correlated with tumorigenesis (p < 0.05). In vitro functional studies showed that ANO9 contributed to tumor cell proliferation, apoptosis, and invasion. Moreover, investigation of clinical CRC specimens showed that ANO9 were markedly overexpressed in metastatic tissue compared with primary tissue. Decreased expression of ANO9 was correlated with poor prognostic outcomes. Conclusions: This study highlighted the role of ANO9 in progression and metastasis of stage II and III CRC. These findings suggested that up-regulation of ANO9, as a metastasis-related gene, could be a novel approach for inhibiting CRC progression. PMID:26317553

    This study examines functional outcome (speech and swallowing), survival, and disease control in patients receiving an intensified treatment regimen with primary aggressive surgery, and postoperative radiotherapy or postoperative concomitant chemoradiotherapy, for previously untreated, resectable, stage III and IV squamous cell carcinoma (SCC) of the tongue base. Sixty-six consecutive patients treated from June 1997 to June 2006 were followed prospectively through the Multidisciplinary Head and Neck Surgery Reconstruction Clinic. Speech and swallowing data were gathered at four evaluation times during the first year. Speech assessment was conducted by PERCI, Nasometer, and C-AIDS and swallowing assessment by Modified barium swallow, Diet survey and G-tube. Also, the overall survival, disease-specific survival and loco regional control were measured. The average age of the patients was 56.8, 85 % male and 15 % female. All patients had primary surgical resection and 83 % received postoperative radiotherapy and 17 % chemoradiation therapy. Overall survival at 3 years was 80.3 % and 5 years 52.2 %. Disease-specific survival at 3 years was 86.7 % and 5 years was 77.5 %. Local control was 94 %. Distal metastasis and second primary were found to be 7.5 % each. Primary surgical treatment of advanced BOT cancer offers excellent functional outcome, local control and disease-specific survival. PMID:24961437

    Purpose: We analyzed whether the prognosis can differ among Wilms tumors (WT) labeled as Stage III according to currently adopted classification systems. Methods and Materials: Patients with nonanaplastic Stage III WT consecutively registered in two Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) trials (CNR-92, TW-2003) were the subjects in the present analysis. The steady mainstay of therapy was primary nephrectomy, followed by three-drug chemotherapy with vincristine, dactinomycin, doxorubicin, and abdominal radiotherapy (RT). Results: Ninety-nine WT patients met the criteria for classification as Stage III according to a revised version of the National Wilms Tumor Study-3 staging system (51 patients in CNR-92, 48 patients in TW-2003). Regional lymph nodes (LN) were not biopsied in 16 patients. After a median follow-up of 66 months, the 4-year disease-free survival (DFS) and overall survival (OS) rates were 85% {+-} 4% and 92% {+-} 3%, respectively, for the whole group. For 38 children with positive LN, the 4-year DFS rate was 73% {+-} 7%, as opposed to 98% {+-} 2% for the 45 children with Stage III WT according to the other criteria but with negative biopsied LN (p = 0.001). The subgroup with the worst prognosis consisted of children more than 2 years old with positive LN (DFS 67% {+-} 8%). A delay between surgery and RT > 30 days had an adverse impact on the abdominal tumor relapse rate. Conclusions: This study provides further evidence that Stage III tumors with LN metastases might be distinguished from WTs meeting the other criteria for classification as Stage III. The worse outcome of the former may warrant a prospective study on the effects of intensified therapy. A subclassification of Stage III tumors is discussed.

    Purpose: To determine the effectiveness of high-dose conformal radiotherapy to the involved field for patients with Stage III non-small-cell lung cancer (NSCLC). Methods and Materials: Between May 1999 and April 2006, a total of 100 consecutive patients with inoperable Stage IIIA or IIIB NSCLC with a performance score of 0 to 2 and treatment by radical radiotherapy combined with chemotherapy were included. Up to August 2002, 33 patients underwent conventional radiotherapy of 56 Gy to 66 Gy using anteroposterior opposite ports to the primary tumor and elective lymph nodes (conventional group). After September 2002, the remaining 67 patients underwent high-dose radiotherapy of 66 Gy to 84 Gy to the involved volume with three-dimensional (3-D) conformal radiotherapy (conformal group). Results: The median survival was 13.2 months (95% confidence interval [CI], 7.5-18.5 months) in the conventional group and 17.3 months (95% CI, 10.7- 24.0 months) in the conformal group. The overall survival at 3 years were 9.1% (95% CI, -0.7-18.9%) in the conventional group and 31.0% (95% CI, 18.9-43.1%) in the conformal group; the conformal group had a significantly better overall survival (p < 0.05). The radiotherapy method (hazard ratio = 0.55, p < 0.05) and performance status (hazard ratio = 1.48, p < 0.05) were shown to be statistically significant independent prognostic factors. Conclusions: Based on the practical experience reported here, 3-D conformal radiotherapy allowed dose escalation without excessive toxicity, and may improve overall survival rates for patients with Stage III NSCLC.

    This study investigates the prognostic and predictive value of YKL-40 in stage IIB-III melanoma patients who were randomized to adjuvant interferon α-2b (IFN) or observation. Serum YKL-40 was determined postoperatively in patients from the Nordic IFN Trial (n=602), EORTC 18952 (n=246), and EORTC 18991 (n=386) (EORTC, European Organisation for Research and Treatment of Cancer). YKL-40 protein expression was determined in 300 tissue sections of primary melanoma or lymph node metastases from 204 Danish patients from the Nordic IFN Trial. Multivariate Cox analysis (including sex, age, stage, ulceration, YKL-40) showed that elevated baseline YKL-40 level was associated with shorter overall survival (OS) in observation groups from the Nordic IFN Trial and EORTC 18952 [hazard ratio (HR)=1.33; 95% confidence interval (CI) 1.01-1.74; P=0.04], but not in the interferon groups (1-year IFN: HR=0.97; 95% CI 0.76-1.25; P=0.83; 2-years IFN: HR=1.06; 95% CI 0.83-1.34; P=0.64). During follow-up, increases in YKL-40 were significantly associated with shorter OS, but not with recurrence-free survival in univariate analysis. YKL-40 expression was stronger in tumor-associated macrophages than melanoma cells in primary melanoma. High YKL-40 expression in macrophages in lymph node metastases was associated with shorter OS in the observation group (HR=2.76; 95% CI: 1.13-6.76, P=0.02), but not in the interferon-treated groups. YKL-40 was an independent prognostic biomarker of OS in melanoma patients stage IIB-III. High serum YKL-40 in poor-prognosis patients may originate from macrophages in the tumor microenvironment and the melanoma cells. Furthermore, we hypothesize that elevated serum YKL-40 after surgery may predict the efficacy of adjuvant IFN treatment. PMID:27076041

    The objective of this study is to investigate staging system of the stage IIIB and stage IIIC Breast cancer and determine the criteria for an update of the classification system. Since AJCC 6th edition, it is pointed out that stage IIIB showed a worse outcome compared with stage IIIC. Using information from two databases, including the nationwide Korean Breast Cancer Registry (KBCR), three cohorts composed of patients from the Asan Medical Center from 1989 to 2002 (cohort I), from 2003 to 2008 (cohort II), and KBCR from 2003 to 2005 (cohort III) were assembled. New classifications were suggested that rearranged stage IIIB as T1-3N3 disease and stage IIIC as T4 any N disease. From the joint analysis of 9640, invasive breast cancer patients from cohorts I and II showed the stage IIIB group showed a significantly worse DFS (HR 10.4, 95% CI 6.9-15.7) compared with the stage IIIC group (HR 7.2, 95% CI 5.9-8.7). T4d breast cancer showed worse DFS than T4 abc breast cancer but not significant (p = 0.505). The survival of patients with T1N3 and T2N3 tumors was higher than the other groups, and patients with T4N3 tumors showed the worst survival outcomes in terms of DFS, CSS. Using new suggested classification, in cohort III, the stage IIIB HR for CSS was changed from 15.4 (95% CI 10.6-22.1) in the AJCC 6th edition to 12.6 (95% CI 10.1-15.6) in the proposed new staging system. The stage IIIC HR for CSS was changed from 13.3 (95% CI 10.7-16.4) in the AJCC 6th edition to 18.9 (95% CI 14.0-25.6) in the proposed new staging using stage I as a reference. Reclassification of T4 any N disease as stage IIIC and T1-3N3 disease as stage IIIB is appropriate. PMID:26223812

    Purpose: This study is to evaluate the tumor regression over the course of EBRT treatment and to determine the difference of tumor reduction for stage III lung squamous cell cancer (SCC) and adenocarcinoma using CBCT. Methods: Twenty three stage III lung cancer patients treated in our clinic who had daily cone beam CT (CBCT) were selected for this study (16 adenocarcinoma and 7 SCC cases). Patients received prescription dose in the range of 50Gy–71.4Gy (mean =60.3Gy, median =50Gy) at 1.8Gy or 2Gy per fraction. Treatments spanned over a minimum of five weeks. Initial mean volume of the gross tumor volume (GTV) was 123cc (range = 14.7cc–353.3cc). For this study, we choose six sets of CBCTs at an interval of one week, starting from the first fraction of treatment. Daily CBCTs from treatment linac computer were transferred to MIM Software version 6.0. An experienced physician contoured the primary GTV on each slices of the CBCT for these patients. Results: A consistent regression of the GTVs was observed in all patients, except in one patient (adeno case) where GTV did not change. Weekly volumetric reduction was in the range of 11.2%–16.6%. Maximum reductions were noticed in the first two weeks of the treatment cycle; mean overall (for adeno+SCC) reductions were 16.6%, 14.2% in week-1 and week-2, respectively. Mean reduction over five weeks of treatment was 49.8% (range = 0.1%–75.5%). Higher reduction was observed in SCC patients as compare to adenocarcinoma cases (54.9% vs. 47.6%); however, the difference was not statistically significant (p-value > 0.05). Conclusion: Large regression of tumors over the course of EBRT for stage III lung cancer patients was observed. Both SCC and adenocarcinoma responded well; overall reduction for SCC cases was higher. A future study is warranted for determining the co-relation between tumor volume reduction and treatment outcome.

    Purpose To compare the quality of volumetric modulated arc therapy (VMAT) or intensity-modulated radiation therapy (IMRT) plans generated by an automated inverse planning system with that of dosimetrist-generated IMRT treatment plans for patients with stage III lung cancer. Methods and Materials Two groups of eight patients with stage III lung cancer were randomly selected. For group I, the dosimetrists spent their best effort in designing IMRT plans to compete with the automated inverse planning system (mdaccAutoPlan); for group II, the dosimetrists were not in competition and spent their regular effort. Five experienced radiation oncologists independently blind-reviewed and ranked the three plans for each patient, a rank of “1” being the best and “3” the worst. Dosimetric measures were also performed to quantitatively evaluate the three types of plans. Results Blind rankings from different oncologists were generally consistent. For group I, the auto-VMAT, auto-IMRT, and manual-IMRT plans received average ranks of 1.6, 2.13, and 2.18, respectively. The auto-VMAT plans in group I had 10% higher PTV conformality and 24% lower esophagus V70 than the manual-IMRT plans; they also resulted in over 20% higher complication-free tumor control probability (p+) than either type of IMRT plans. The auto- and manual-IMRT plans in this group yielded generally comparable dosimetric measures. For group II, the auto-VMAT, auto-IMRT, and manual-IMRT plans received average ranks of 1.55, 1.75, and 2.75, respectively. Compared to the manual-IMRT plans in this group, the auto-VMAT plans and the auto-IMRT plans showed, respectively, 17% and 14% higher PTV dose conformality, 8% and 17% lower mean lung dose, 17% and 26% lower mean heart dose, and 36% and 23% higher p+. Conclusions mdaccAutoPlan is capable of generating high-quality VMAT and IMRT treatment plans for stage III lung cancer. Manual-IMRT plans could achieve quality similar to auto-IMRT plans if best effort were spent

    Context Randomized trials suggest adjuvant chemotherapy is effective for elderly patients with stage III colon cancer. However, the elderly are less likely to receive this therapy than younger patients, perhaps because of concern about adverse effects. Objective To evaluate adjuvant chemotherapy use and outcomes for older patients with stage III colon cancer from well-defined population-based settings and healthcare systems. Design Observational study of adjuvant chemotherapy use and outcomes by age, using Poisson regression to estimate the number of adverse events adjusted for demographic and clinical factors, including comorbid illness and specific elements of chemotherapy regimens documented with clinically detailed medical record reviews and patient and surrogate surveys. Setting Five geographically defined regions (Alabama, Iowa, Los Angeles County, Northern California, and North Carolina), five integrated health-care delivery systems, and 15 Veterans hospitals. Patients All 675 patients diagnosed with stage III colon cancer during 2003-2005 who underwent surgical resection were followed up to 15 months post-diagnosis. Main outcome measures Chemotherapy regimen, dose, duration and annualized mean number of adverse events stratified by age. Results Half of the 202 patients >=75 years received adjuvant chemotherapy compared with 87% of 473 younger patients (diff 37%, 95% CI 30%-45%). Among adjuvant chemotherapy users, 14 (14%) of patients >=75 years and 178 (44%) of younger patients received a regimen containing oxaliplatin (diff 30%, 95% CI 21%-38%). Older patients were less likely to continue. By 150 days, 99 (40%) patients >= 65 years and 68 (25%) younger patients had discontinued chemotherapy (diff 15%, 95% CI 7%-23%). Overall, 162 (24%) patients had at least one adverse clinical event, with more events among patients treated with vs. without adjuvant chemotherapy (mean 0.394 vs. 0.160, diff 0.234, 95% CI 0.11-0.36, p<0.001).

    At the Urological Clinic in Hradec Králové in 1975-1989 a total of 182 patients with germ cell tumours of the testis--nonseminomas were treated. Of these patients 37 were in stage III-IV (20%). In 27 (72.9%) initial chemotherapy was administered, since 1980 combined with cisplatinum, as outlined. In 20 patients also revision of retroperitoneal nodes (54%) was made, to 19 patients adjuvant chemotherapy was administered (5th and 6th cycle). In 12 patients irradiation was indicated (32.4%). Histological examination of the preparation removed from the retroperitoneum was implemented in 15 patients: in four a vital tumour was revealed, in two a mature teratoma and in nine fibrosis or necrosis of a metastatic tumour was found. In seven patient a relapse of the disease occurred, 14 patients survive for 1-15 years. Twenty-three patients died. PMID:1822636

    A total of 277 patients with untreated Hodgkin's disease, clinical stages I-II, were randomized to cyclophosphamide, vinblastine, procarbazine, and prednisone (CVPP) alone for 6 monthly cycles or to CVPP plus radiation therapy (RT), 3,000 rad, to involved areas (CVPP plus RT). One or more of the following factors were considered as unfavorable prognosis: age greater than 45 years, more than two lymph node areas involved, or bulky disease. In the favorable group, disease-free survival (77% vs. 70%) or overall survival (92% vs. 91%) at 84 months for CVPP versus RT plus CVPP was similar. Patients with unfavorable prognosis treated with RT plus CVPP had longer disease-free survival (75% vs. 34%) (P = .001) and overall survival (84% vs. 66%) than patients treated with CVPP alone.

    Purpose: Collaboration between specialists is essential for achieving high-value care in patients with complex cancer needs. We explore how collaboration between oncologists and surgeons affects mortality and cost for patients requiring multispecialty cancer care. Patients and Methods: This was a retrospective cohort study of patients with stage III colon cancer from SEER-Medicare diagnosed between 2000 and 2009. Patients were assigned to a primary treating surgeon and oncologist. Collaboration between surgeon and oncologist was measured as the number of patients shared between them; this has been shown to reflect advice seeking and referral relationships between physicians. Outcomes included hazards for all-cause mortality, subhazards for colon cancer–specific mortality, and cost of care at 12 months. Results: A total of 9,329 patients received care from 3,623 different surgeons and 2,319 medical oncologists, representing 6,827 unique surgeon–medical oncologist pairs. As the number of patients shared between specialists increased from to one to five (25th to 75th percentile), patients experienced an approximately 20% improved survival benefit from all-cause and colon cancer–specific mortalities. Specifically, for each additional patient shared between oncologist and surgeon, all-cause mortality improved by 5% (hazard ratio, 0.95; 95%CI, 0.92 to 0.97), and colon cancer–specific mortality improved by 5% (subhazard ratio, 0.95; 95% CI, 0.91 to 0.97). There was no association with cost. Conclusion: Specialist collaboration is associated with lower mortality without increased cost among patients with stage III colon cancer. Facilitating formal and informal collaboration between specialists may be an important strategy for improving the care of patients with complex cancers. PMID:25873063

    Background Somatic mutations in PIK3CA (phosphatidylinositol-4,5-bisphosphonate 3-kinase [PI3K], catalytic subunit alpha gene) activate the PI3K-AKT signaling pathway and contribute to pathogenesis of various malignancies, including colorectal cancer. Methods We examined associations of PIK3CA oncogene mutation with relapse, survival, and treatment efficacy in 627 stage III colon carcinoma case subjects within a randomized adjuvant chemotherapy trial (5-fluorouracil and leucovorin [FU/LV] vs irinotecan [CPT11], fluorouracil and leucovorin [IFL]; Cancer and Leukemia Group B 89803 [Alliance]). We detected PIK3CA mutation in exons 9 and 20 by polymerase chain reaction and pyrosequencing. Cox proportional hazards model was used to assess prognostic and predictive role of PIK3CA mutation, adjusting for clinical features and status of routine standard molecular pathology features, including KRAS and BRAF mutations and microsatellite instability (mismatch repair deficiency). All statistical tests were two-sided. Results Compared with PIK3CA wild-type cases, overall status of PIK3CA mutation positivity or the presence of PIK3CA mutation in either exon 9 or 20 alone was not statistically significantly associated with recurrence-free, disease-free, or overall survival (log-rank P > .70; P > .40 in multivariable regression models). There was no statistically significant interaction between PIK3CA and KRAS (or BRAF) mutation status in survival analysis (P interaction > .18). PIK3CA mutation status did not appear to predict better or worse response to IFL therapy compared with FU/LV therapy (P interaction > .16). Conclusions Overall tumor PIK3CA mutation status is not associated with stage III colon cancer prognosis. PIK3CA mutation does not appear to serve as a predictive tumor molecular biomarker for response to irinotecan-based adjuvant chemotherapy. PMID:24231454

    Background Despite improved survival with chemotherapy for stage III colorectal cancer (CRC), patients may suffer substantial economic hardship during treatment. Methods for quantifying financial burden in CRC patients are lacking. Objective To derive and validate a novel patient-reported measure of personal financial burden during CRC treatment. Data Collection Within a population-based survey of patients in the Detroit and Georgia Surveillance, Epidemiology and End Results regions diagnosed with stage III CRC between 2011 and 2013, we asked 7 binary questions assessing effects of disease and treatment on personal finances. Data Analysis We used factor analysis to compute a composite measure of financial burden. We used χ2 tests to evaluate relationships between individual components of financial burden and chemotherapy use with χ2 analyses. We used Mantel-Haenszel χ2 trend tests to examine relationships between the composite financial burden metric and chemotherapy use. Results Among 956 patient surveys (66% response rate), factor analysis of 7 burden items yielded a single-factor solution. Factor loadings of 6 items were >0.4; these were included in the composite score. Internal consistency was high (Cronbach α = 0.79). The mean financial burden score among all respondents was 1.72 (range, 0–6). The 812 (85%) who reported chemotherapy use had significantly higher financial burden scores than those who did not (mean burden score 1.88 vs. 0.88, P < 0.001). Conclusions Financial burden is high among CRC patients, particularly those who use adjuvant chemotherapy. We encourage use of our instrument to validate our measure in the identification of patients in need of additional financial support during treatment. PMID:25304021

    Purpose To establish a new clinical staging standard for nasopharyngeal carcinoma (NPC), based on intensity-modulated radiotherapy (IMRT), through a prospective multicenter clinical trial. Experiment Design 492 NPC patients were selected from six hospitals in the Guangxi Zhuang Autonomous Region, China from January 2006 to December 2009. Kaplan-Meier method was adopted to calculate survival rates. Log-rank test was used to compare survival differences. Results According to the seventh edition of the UICC/AJCC staging system, the differences between T1, T2 and T3 are not statistically significant, suggesting that T1, T2 and T3 could be combined as new T1. There were significant differences between all N stages except those of N3a and N3b, suggesting that N3a and N3b could be combined as new N3. Additionally, the overall survival (OS) curves of stages I, II, III and IVa were not significantly different. Therefore, we propose a new clinical NPC staging standard based on magnetic resonance imaging (MRI) and IMRT as T stage (including T1 and T2), N stage (including N0, N1, N2 and N3) and clinical staging includes I (T1N0M0), II (T1N1-2M0, T2N0M0), III (T2N1-2M0), IVa (TxN3M0) and IVb (TxNxM1). Recommended staging system performs better in risk difference and distribution balance. Furthermore, the differences in the 5-year curves of local relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and OS were all statistically more significant than the seventh edition of the UICC/AJCC staging system. Conclusions Proposed staging system is more adaptable to IMRT and predicts the prognosis of NPC patients more accurately. PMID:26918446

    Several independent serum biomarkers have been proposed as prognostic and/or predictive markers for colorectal cancer (CRC). To this date, carcinoembryonic antigen (CEA) remains the only recommended serological CRC biomarker. The present retrospective analysis investigates the prognostic value of several serum markers. A total of 256 patients with rectal cancer underwent surgery for curative intent in a university cancer center between January 1988 and June 2007. Preoperative serum was retrospectively analyzed for albumin, alkaline phosphatase (aP), beta-human chorionic gonadotropin, bilirubin, CA 125, cancer antigen 19-9, cancer antigen 72-4 (CA 72-4), CEA, CRP, CYFRA 21-1, ferritin, gamma-glutamyl transpeptidase, glutamate oxaloacetate transanunase, glutamate pyruvate transaminase, hemoglobin, haptoglobin, interleukin-6, interleukin-8, creatinine, lactate-dehydrogenase, serum amyloid A (SAA), and 25-hydroxyvitamin D. Cancer-specific survival (CSS) and disease-free survival (DFS) were estimated. Median follow-up time was 8.4 years. Overall 3- and 5-year CSS was 88.6 and 78.9 %, respectively. DFS rates were 72.8 % (3 years) and 67.5 % (5 years). Univariate analysis of CSS indicated aP, CA 72-4, CEA, and SAA as prognostic factors, while aP, CEA, and SAA were also prognostic with regard to DFS. Multivariate analysis confirmed SAA together with T and N stage as prognostic factors. According to UICC stage, CEA and SAA add prognostic value in stages II and III with regard to DFS and CSS, respectively. The combined use of CEA and SAA is able to identify patients with favorable and poor prognosis. In addition to tumor baseline parameters, routine analysis of SAA together with CEA provided markedly improved prognostic value on CSS and DFS in resected rectal cancer. PMID:25027407

    Purpose/Objectives(s): Early-stage endometrial cancer patients are at higher risk of noncancer mortality than of cancer mortality. Competing event models incorporating comorbidity could help identify women most likely to benefit from treatment intensification. Methods and Materials: 67,397 women with stage I-II endometrioid adenocarcinoma after total hysterectomy diagnosed from 1988 to 2009 were identified in Surveillance, Epidemiology, and End Results (SEER) and linked SEER-Medicare databases. Using demographic and clinical information, including comorbidity, we sought to develop and validate a risk score to predict the incidence of competing mortality. Results: In the validation cohort, increasing competing mortality risk score was associated with increased risk of noncancer mortality (subdistribution hazard ratio [SDHR], 1.92; 95% confidence interval [CI], 1.60-2.30) and decreased risk of endometrial cancer mortality (SDHR, 0.61; 95% CI, 0.55-0.78). Controlling for other variables, Charlson Comorbidity Index (CCI) = 1 (SDHR, 1.62; 95% CI, 1.45-1.82) and CCI >1 (SDHR, 3.31; 95% CI, 2.74-4.01) were associated with increased risk of noncancer mortality. The 10-year cumulative incidences of competing mortality within low-, medium-, and high-risk strata were 27.3% (95% CI, 25.2%-29.4%), 34.6% (95% CI, 32.5%-36.7%), and 50.3% (95% CI, 48.2%-52.6%), respectively. With increasing competing mortality risk score, we observed a significant decline in omega (ω), indicating a diminishing likelihood of benefit from treatment intensification. Conclusion: Comorbidity and other factors influence the risk of competing mortality among patients with early-stage endometrial cancer. Competing event models could improve our ability to identify patients likely to benefit from treatment intensification.

    Abstract In 2010, World Health Organization (WHO) reclassified pancreatic neuroendocrine tumors (p-NETs) into 4 main groups: neuroendocrine tumor G1 (NET G1), neuroendocrine tumor G2 (NET G2), neuroendocrine carcinoma G3 (NEC G3), mixed adeno and neuroendocrine carcinoma (MANEC). Clinical value of these newly updated WHO grading criteria has not been rigorously validated. The authors aimed to evaluate the clinical consistency of the new 2010 grading classifications by WHO and the 2010 tumor-node metastasis staging systems by American Joint Committee on Cancer (AJCC) on survivals for patients with surgically resected p-NETs. Moreover, the authors would validate the prognostic value of both criteria for p-NETs. The authors retrospectively collected the clinicopathologic data of 120 eligible patients who were all surgically treated and histopathologically diagnosed as p-NETs from January 2004 to February 2014 in our single institution. The new WHO criteria were assigned to 4 stratified groups with a respective distribution of 62, 35, 17, and 6 patients. Patients with NET G1 or NET G2 obtained a statistically better survival compared with those with NEC G3 or MANEC (P < 0.001). Survivals of NET G1 was also better than those of NET G2 (P = 0.023), whereas difference of survivals between NEC G3 and MANEC present no obvious significance (P = 0.071). The AJCC 2010 staging systems were respectively defined in 61, 36, 12, and 11 patients for each stage.

    Introduction The Institute of Medicine, the American Society of Clinical Oncology, and the European Society of Medical Oncology promote a multidisciplinary approach for the treatment of cancer. Stage III non-small-cell lung cancer (NSCLC) represents a heterogeneous group of diseases necessitating coordination of care among medical, radiation, and surgical oncology. The optimal care of stage III NSCLC underscores the need for a multidisciplinary approach. Methods From tumor registry data, we identified all cases of stage III NSCLC seen at Lehigh Valley Health Network between March 2010 and March 2013. The care received by patients when seen in the thoracic multidisciplinary clinic (MDC) was compared with the care received when not seen in the thoracic MDC. Results All patients seen in the MDC, compared to <50% of patients seen outside the MDC, were evaluated by more than one physician prior to beginning the treatment. Time to initiate treatment was shorter in MDC patients than in non-MDC patients. Patients seen in the MDC had a greater concordance with clinical pathways. A greater percentage of patients seen in the thoracic MDC had pathologic staging of their mediastinum. Patients seen in the MDC were more likely to receive all of their care at Lehigh Valley Health Network. Conclusion Multidisciplinary care is essential in the treatment of patients with stage III NSCLC. Greater utilization of MDCs for this complex group of patients will result in more efficient coordination of care, pretreatment evaluation, and therapy, which in turn should translate to improve patients’ outcomes.

    Purpose: To assess the dosimetric impact of interplay between spot-scanning proton beam and respiratory motion in intensity-modulated proton therapy (IMPT) for stage III lung cancer. Methods: Eleven patients were sampled from 112 patients with stage III nonsmall cell lung cancer to well represent the distribution of 112 patients in terms of target size and motion. Clinical target volumes (CTVs) and planning target volumes (PTVs) were defined according to the authors' clinical protocol. Uniform and realistic breathing patterns were considered along with regular- and hypofractionation scenarios. The dose contributed by a spot was fully calculated on the computed tomography (CT) images corresponding to the respiratory phase that the spot is delivered, and then accumulated to the reference phase of the 4DCT to generate the dynamic dose that provides an estimation of what might be delivered under the influence of interplay effect. The dynamic dose distributions at different numbers of fractions were compared with the corresponding 4D composite dose which is the equally weighted average of the doses, respectively, computed on respiratory phases of a 4DCT image set. Results: Under regular fractionation, the average and maximum differences in CTV coverage between the 4D composite and dynamic doses after delivery of all 35 fractions were no more than 0.2% and 0.9%, respectively. The maximum differences between the two dose distributions for the maximum dose to the spinal cord, heart V40, esophagus V55, and lung V20 were 1.2 Gy, 0.1%, 0.8%, and 0.4%, respectively. Although relatively large differences in single fraction, correlated with small CTVs relative to motions, were observed, the authors' biological response calculations suggested that this interfractional dose variation may have limited biological impact. Assuming a hypofractionation scenario, the differences between the 4D composite and dynamic doses were well confined even for single fraction. Conclusions: Despite

    Context A family history of colorectal cancer in a first-degree relative increases the risk of developing colorectal cancer. However, the influence of family history on cancer recurrence and survival among patients with established disease remains uncertain. Objective To examine the association of family history of colorectal cancer with cancer recurrence and survival of patients with colon cancer. Design, Setting, and Participants Prospective observational study of 1,087 patients with stage III colon cancer enrolled in a randomized adjuvant chemotherapy trial (CALGB 89803) between April 1999 and May 2001. Patients provided data on family history at baseline and were followed up until March 2007 for disease recurrence and death (median follow-up 5.6 years). In a subset of patients, we assessed microsatellite instability (MSI) and expression of the mismatch repair (MMR) proteins, MLH1 and MSH2, in tumor specimens. Main Outcome Measure Disease-free survival, recurrence-free survival, and overall survival according to the presence or absence of a family history of colorectal cancer. Results Among 1,087 eligible patients, 195 (17.9%) reported a family history of colorectal cancer in a first-degree relative. Cancer recurrence or death occurred in 57/195 patients (29%; 95% confidence interval [CI], 23%-36%) with a family history of colorectal cancer and 343/892 patients (38%; 95% CI, 35%-42%) without a family history. Compared to patients without a family history, the adjusted hazard ratios (HR) among those with ≥1 affected first-degree relatives were 0.72 (95% CI, 0.54-0.96) for disease-free survival (DFS), 0.74 (95% CI, 0.55-0.99) for recurrence-free survival (RFS), and 0.75 (95% CI, 0.54-1.05) for overall survival (OS). This reduction in risk of cancer recurrence or death associated with a family history became stronger with an increasing number of affected first-degree relatives. Compared to participants without a family history of colorectal cancer, those with 1

    ABSTRACT Purpose: To determine the effectiveness of adjuvant dendritic cell (DC) vaccination to induce tumor-specific immunological responses in stage III melanoma patients. Experimental design: Retrospective analysis of stage III melanoma patients, vaccinated with autologous monocyte-derived DC loaded with tumor-associated antigens (TAA) gp100 and tyrosinase after radical lymph node dissection. Skin-test infiltrating lymphocytes (SKILs) obtained from delayed-type hypersensitivity skin-test biopsies were analyzed for the presence of TAA-specific CD8+ T cells by tetrameric MHC-peptide complexes and by functional TAA-specific T cell assays, defined by peptide-recognition (T2 cells) and/or tumor-recognition (BLM and/or MEL624) with specific production of Th1 cytokines and no Th2 cytokines. Results: Ninety-seven patients were analyzed: 21 with stage IIIA, 34 with stage IIIB, and 42 had stage IIIC disease. Tetramer-positive CD8+ T cells were present in 68 patients (70%), and 24 of them showed a response against all 3 epitopes tested (gp100:154–162, gp100:280–288, and tyrosinase:369–377) at any point during vaccinations. A functional T cell response was found in 62 patients (64%). Rates of peptide-recognition of gp100:154–162, gp100:280–288, and tyrosinase:369–377 were 40%, 29%, and 45%, respectively. Median recurrence-free survival and distant metastasis-free survival of the whole study population were 23.0 mo and 36.8 mo, respectively. Conclusions: DC vaccination induces a functional TAA-specific T cell response in the majority of stage III melanoma patients, indicating it is more effective in stage III than in stage IV melanoma patients. Furthermore, performing multiple cycles of vaccinations enhances the chance of a broader immune response. PMID:27622047

    Background Most patients with ovarian cancer are diagnosed with advanced stage disease (i.e., stage III-IV), which is associated with a poor prognosis. Differentially expressed genes (DEGs) in stage III serous ovarian carcinoma compared to normal tissue were screened by a new differential display method, the annealing control primer (ACP) system. The potential targets for markers that could be used for diagnosis and prognosis, for stage III serous ovarian cancer, were found by cluster and survival analysis. Methods The ACP-based reverse transcriptase polymerase chain reaction (RT PCR) technique was used to identify DEGs in patients with stage III serous ovarian carcinoma. The DEGs identified by the ACP system were confirmed by quantitative real-time PCR. Cluster analysis was performed on the basis of the expression profile produced by quantitative real-time PCR and survival analysis was carried out by the Kaplan-Meier method and Cox proportional hazards multivariate model; the results of gene expression were compared between chemo-resistant and chemo-sensitive groups. Results A total of 114 DEGs were identified by the ACP-based RT PCR technique among patients with stage III serous ovarian carcinoma. The DEGs associated with an apoptosis inhibitory process tended to be up-regulated clones while the DEGs associated with immune response tended to be down-regulated clones. Cluster analysis of the gene expression profile obtained by quantitative real-time PCR revealed two contrasting groups of DEGs. That is, a group of genes including: SSBP1, IFI6 DDT, IFI27, C11orf92, NFKBIA, TNXB, NEAT1 and TFG were up-regulated while another group of genes consisting of: LAMB2, XRCC6, MEF2C, RBM5, FOXP1, NUDCP2, LGALS3, TMEM185A, and C1S were down-regulated in most patients. Survival analysis revealed that the up-regulated genes such as DDAH2, RNase K and TCEAL2 might be associated with a poor prognosis. Furthermore, the prognosis of patients with chemo-resistance was predicted to be

    This prospective study was designed to compare the hair levels of 36 elements in 52 patients with stage III breast cancer to those of an equal number of healthy individuals. Principal component and cluster analysis were used for source of identification and apportionment of heavy metals and trace elements in these two groups. A higher average level of iron was found in samples from patients while controls had higher levels of calcium. Both patients and controls had elevated levels of tin, magnesium, zinc, and sodium. Almost all element values in cancer patients showed higher dispersion and asymmetry than in healthy controls. Between the two groups, there were statistically significant differences in the concentrations of silver, arsenic, gold, boron, barium, beryllium, calcium, cadmium, cerium, cobalt, cesium, gadolinium, manganese, nickel, lead, antimony, scandium, selenium, and zinc (p < 0.05). Strong positive correlations were found between lead and gold (r = 0.785) in the cancer group and between palladium and cobalt (r = 0.945) in the healthy individuals. Our results show that there are distinct patterns of heavy metals and trace elements in the hair of breast cancer patients in comparison to healthy controls. These results could be of significance in the diagnosis of breast cancer. PMID:21660533

    A 58-year-old woman, a heavy smoker, was diagnosed with stage III squamous cell lung cancer. She was treated with concurrent chemotherapy and radiotherapy, with partial response. 2 months later, she had haemoptysis caused by brisk bleeding from the radiated right upper lobe. Fortunately, her bleed was self-limited. 4 months later, a rapidly enlarging renal mass was discovered and turned out to be metastatic from the lung primary. Second-line chemotherapy with docetaxel and ramucirumab did not have effects on the renal mass after 2 cycles. Despite not being eligible for a durvalumab trial because of lack of PD-L1 expression, she had a meaningful response to nivolumab. Once every 2 weeks, infusion of nivolumab resulted in rapid tumour shrinkage in multiple areas. In the next few months, she experienced a variety of side effects, some of which were potentially life-threatening. She had disease progression 9 months into treatment. PMID:27389724

    The efficiency of small bowel double-contrast enema in the detection and localization of tumor- or therapy-induced lesions of the intestine was studied retrospectively in 43 patients with stage III ovarian carcinoma. The radiographic findings in 62 examinations were verified by operative and autopsy findings and by the clinical course. Postoperative changes in the small bowel were noted in 69% of the patients (63% moderate, 6% severe). Signs of acute radiation enteritis were found in 36% (all moderate). Signs of chronic radiation enteropathy were detected in 71% (53% moderate, 18% severe). Small bowel obstruction due to recurrent tumor was correctly identified in 9%. Nonobstructing peritoneal implants were detected in 27% of the patients. The small bowel double-contrast enema is accurate in localizing lesions resulting from adhesions, acute and chronic radiation enteritis, or obstructing tumor; it is less efficient in detecting nonobstructive peritoneal metastases. The major clinical value of this examination is its ability to differentiate "dysfunctional intestine," which is managed conservatively, from focal obstruction requiring surgery. The radiographic features of chronic radiation enteritis on double-contrast enema examination are discussed in detail. PMID:6607594

    A review of 92 patients with Stage III nonseminomatous tumors treated at Roswell Park Memorial Institute between 1970-1979 was undertaken to verify changes in concepts as related to multiple agent chemotherapy and cytoreductive surgery. Each patient had a minimal follow-up of 18 months. Fifty-three patients were seen before 1975. Eighteen had metastasis to the lungs only. These were treated with a variety of single chemotherapeutic agents and cytoreductive surgery. The survival of this group was 38%. Among 35 patients with lung and visceral involvement seen at the same time, only one patient is alive. Thirty-nine patients were seen after 1975 and treated with multi-drug chemotherapy and cytoreductive surgery. The current survival rate of 23 patients with lung metastasis only is 69%. Among 16 patients with lung and visceral involvement, the present survival rate is 31%. This report confirms the effectiveness of multi-drug therapy in conjunction with cytoreductive surgery in the treatment of disseminated testicular tumors. PMID:6186354

    The survival in cutaneous malignant melanoma (CMM) is highly dependent on the stage of the disease. Stage III-IV CMM patients are at high risk of relapse with a heterogeneous outcome, but not all experience excess mortality due to their disease. This group is referred to as the cure proportion representing the proportion of patients who experience the same mortality rate as the general population. The aim of this study was to estimate the cure proportion of patients diagnosed with Stage III-IV CMM in Sweden. From the population-based Swedish Melanoma Register, we included 856 patients diagnosed with primary Stage III-IV CMM, 1990-2007, followed-up through 2013. We used flexible parametric cure models to estimate cure proportions and median survival times (MSTs) of uncured by sex, age, tumor site, ulceration status (in Stage III patients) and disease stage. The standardized (over sex, age and site) cure proportion was lower in Stage IV CMMs (0.15, 95% CI 0.09-0.22) than non-ulcerated Stage III CMMs (0.48, 95% CI 0.41-0.55) with a statistically significant difference of 0.33 (95% CI = 0.24-0.41). Ulcerated Stage III CMMs had a cure proportion of 0.27 (95% CI 0.21-0.32) with a statistically significant difference compared to non-ulcerated Stage III CMMs (difference 0.21; 95% CI = 0.13-0.30). The standardized MST of uncured was approximately 9-10 months longer for non-ulcerated versus ulcerated Stage III CMMs. We could demonstrate a significantly better outcome in patients diagnosed with non-ulcerated Stage III CMMs compared to ulcerated Stage III CMMs and Stage IV disease after adjusting for age, sex and tumor site.

    Carcinoembryonic antigen (CEA) remains the only recommended biomarker for follow-up care of colorectal cancer (CRC), but besides CEA, several other serological parameters have been proposed as prognostic markers for CRC. The present retrospective analysis investigates a comprehensive set of serum markers with regard to cancer-specific survival (CSS) and disease-free survival (DFS). A total of 472 patients with colon cancer underwent surgery for curative intent between January 1988 and June 2007. Preoperative serum was analyzed for the following parameters: albumin, alkaline phosphatase (aP), beta-human chorionic gonadotropin (βhCG), bilirubin, cancer antigen 125 (CA 125), cancer antigen 19-9 (CA 19-9), CA 72-4, CEA, C-reactive protein (CRP), cytokeratin-19 soluble fragment (CYFRA 21-1), ferritin, gamma-glutamyltransferase (γGT), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), hemoglobin, haptoglobin, interleukin-6, interleukin-8, creatinine, lactate dehydrogenase (LDH), serum amyloid A (SAA), and 25-hydroxyvitamin D. After a median follow-up period of 5.9 years, the overall 3- and 5-year CSS was 91.7 and 84.9 % and DFS rates were 82.7 % (3 years) and 77.6 % (5 years). Multivariate analyses confirmed preoperative CEA as an independent prognostic factor with regard to CSS and DFS. CA 19-9 and γGT also provided prognostic value for CSS and DFS, respectively. Younger age was negatively associated with DFS. According to UICC stage, CEA provided significant prognostic value with regard to CSS and DFS, while CA 19-9 was only prognostic for CSS. Combined analysis is able to identify patients with favorable prognosis. In addition to tumor baseline parameters, preoperative CEA could be confirmed as prognostic marker in colon cancer. CA 19-9 and γGT also provide additional prognostic value with regard to survival and recurrence in stage III and stage I disease, respectively. The combined use of CEA together with CA 19-9 and γGT improve

    Objectives. The aim of this study was to investigate the feasibility and safety of percutaneous 125I seed permanent implantation for advanced hypopharyngeal carcinoma from toxicity, tumor response, and short-term outcome. Methods. 125I seeds implant procedures were performed under computed tomography for 34 patients with advanced hypopharyngeal carcinoma. We observed the local control rate, overall survival, and acute or late toxicity rate. Results. In the 34 patients (stage III, n=6; stage IV, n=28), the sites of origin were pyriform sinus (n=29) and postcricoid area (n=5). All patients also received one to four cycles of chemotherapy after seed implantation. The post-plan showed that the actuarial D90 of 125I seeds ranged from 90 to 158 Gy (median, 127 Gy). The mean follow-up was 12.3 months (range, 3.4 to 43.2 months). The local control was 2.1–31.0 months with a median of 17.7 months (95% confidence interval [CI], 13.4 to 22.0 months). The 1-, 2-, and 3-year local controls were 65.3%, 28.6%, and 9.5% respectively. Twelve patients (35%) died of local recurrence, fourteen patients (41%) died of distant metastases, and three patients (9%) died of recurrence and metastases at the same time. Five patients (15%) still survived to follow-up. At the time of analysis, the median survival time was 12.5 months (95% CI, 9.5 to 15.4 months). The 1-, 2-, and 3-year overall survival rates were 55.2%, 20.3%, and 10.9%, respectively. Five patients (15%) experienced grade 3 toxic events and nine patients (26%) have experienced grade 2 toxic events. Conclusion. This review shows relatively low toxicity for interstitial 125I seed implantation in the patients with advanced stage hypopharyngeal cancer. The high local control results suggest that 125I seed brachytherapy implant as a salvage or palliative treatment for advanced hypopharyngeal carcinoma merit further investigation. PMID:27440132

    We previously reported that the prognosis of microsatellite instability high (MSI-H) gastric cancer is similar to that of MSI-low/microsatellite stable (MSI-L/MSS) gastric cancer. The reason for this seemed to be related to the effects of chemotherapy. To verify this hypothesis, we expanded the study population and reanalyzed the prognosis of MSI-H gastric cancer. Data from 1,276 patients with Stage II and III gastric cancer who underwent gastrectomy with curative intent between January 2005 and June 2010 were reviewed. The prognosis of MSI-H tumors in comparison with MSI-L/MSS tumors was analyzed, according to the administration of chemotherapy and other clinicopathologic features. A total of 361 (28.3%) patients did not receive chemotherapy (MSI-H = 47 and MSI-L/MSS = 314), whereas 915 (71.7%) patients did receive chemotherapy (MSI-H = 58 and MSI-L/MSS = 857). The hazard ratio of MSI-H versus MSI-L/MSS was 0.49 (95% confidence interval: 0.26-0.94, p = 0.031) when chemotherapy was not received and 1.16 (95% confidence interval: 0.78-1.71, p = 0.466) when chemotherapy was received. In subgroup analyses, the prognosis of MSI-H was better in Stage III, women, with lymph node metastasis, and undifferentiated histology subgroups when chemotherapy was not received. However, in patients treated with chemotherapy, prognosis was worse for MSI-H tumors in Stage III, undifferentiated histology, and diffuse type subgroups of gastric cancer. In conclusion, MSI-H tumors were associated with a good prognosis in Stage II and III gastric cancer when patients were treated by surgery alone, and the benefits of MSI-H status were attenuated by chemotherapy.

    Backgrounds Preventing distant recurrence and achieving local control are important challenges in rectal cancer treatment, and use of adjuvant chemotherapy has been studied. However, no phase III study comparing adjuvant chemotherapy regimens for rectal cancer has demonstrated superiority of a specific regimen. We therefore conducted a phase III study to evaluate the superiority of S-1 to tegafur–uracil (UFT), a standard adjuvant chemotherapy regimen for curatively resected stage II/III rectal cancer in Japan, in the adjuvant setting for rectal cancer. Patients and methods The ACTS-RC trial was an open-label, randomized, phase III superiority trial conducted at 222 sites in Japan. Patients aged 20–80 with stage II/III rectal cancer undergoing curative surgery without preoperative therapy were randomly assigned to receive UFT (500–600 mg/day on days 1–5, followed by 2 days rest) or S-1 (80–120 mg/day on days 1–28, followed by 14 days rest) for 1 year. The primary end point was relapse-free survival (RFS), and the secondary end points were overall survival and adverse events. Results In total, 961 patients were enrolled from April 2006 to March 2009. The primary analysis was conducted in 480 assigned to receive UFT and 479 assigned to receive S-1. Five-year RFS was 61.7% [95% confidence interval (CI) 57.1% to 65.9%] for UFT and 66.4% (95% CI 61.9% to 70.5%) for S-1 [P = 0.0165, hazard ratio (HR): 0.77, 95% CI 0.63–0.96]. Five-year survival was 80.2% (95% CI 76.3% to 83.5%) for UFT and 82.0% (95% CI 78.3% to 85.2%) for S-1. The main grade 3 or higher adverse events were increased alanine aminotransferase and diarrhea (each 2.3%) in the UFT arm and anorexia, diarrhea (each 2.6%), and fatigue (2.1%) in the S-1 arm. Conclusion One-year S-1 treatment is superior to UFT with respect to RFS and has therefore become a standard adjuvant chemotherapy regimen for stage II/III rectal cancer following curative resection.

    Sentinel lymph node biopsy is used to stage Merkel cell carcinoma, but its prognostic value has been questioned. Furthermore, predictors of outcome in sentinel lymph node positive Merkel cell carcinoma patients are poorly defined. In breast carcinoma, isolated immunohistochemically positive tumor cells have no impact, but in melanoma they are considered significant. The significance of sentinel lymph node metastasis tumor burden (including isolated tumor cells) and pattern of involvement in Merkel cell carcinoma are unknown. In this study, 64 Merkel cell carcinomas involving sentinel lymph nodes and corresponding immunohistochemical stains were reviewed and clinicopathological predictors of outcome were sought. Five metastatic patterns were identified: (1) sheet-like (n=38, 59%); (2) non-solid parafollicular (n=4, 6%); (3) sinusoidal, (n=11, 17%); (4) perivascular hilar (n=1, 2%); and (5) rare scattered parenchymal cells (n=10, 16%). At the time of follow-up, 30/63 (48%) patients had died with 21 (33%) attributable to Merkel cell carcinoma. Patients with pattern 1 metastases had poorer overall survival compared with patients with patterns 2-5 metastases (P=0.03), with 22/30 (73%) deaths occurring in pattern 1 patients. Three (10%) deaths occurred in patients showing pattern 5, all of whom were immunosuppressed. Four (13%) deaths occurred in pattern 3 patients and 1 (3%) death occurred in a pattern 2 patient. In multivariable analysis, the number of positive sentinel lymph nodes (1 or 2 versus >2, P<0.0001), age (<70 versus ≥70, P=0.01), sentinel lymph node metastasis pattern (patterns 2-5 versus 1, P=0.02), and immune status (immunocompetent versus suppressed, P=0.03) were independent predictors of outcome, and could be used to stratify Stage III patients into three groups with markedly different outcomes. In Merkel cell carcinoma, the pattern of sentinel lymph node involvement provides important prognostic information and utilizing this data with other

    BACKGROUND--Carcinoma of the lung with thoracic wall involvement constitutes stage III disease. The management of patients with this condition is complicated. However, improvement in perioperative care coupled with advances in surgical technique have enabled a more aggressive approach to the problem to be adopted. METHODS--A retrospective review was carried out of 58 patients (40 men) of mean age 63 years who underwent thoracotomy for lung cancer with chest wall invasion between 1980 and 1993. RESULTS--Chest wall resection was performed in 55 patients (94.8%); in three patients the discovery of N2 disease at operation precluded resection. The TNM status was T3N0M0 in 38 patients, T3N1M0 in 13, and T3N2M0 in seven. Squamous cell carcinoma was the commonest cell type (26 patients). Reconstruction of the chest wall was performed in 29 patients (Marlex mesh in six, Marlex-methacrylate in 22, myocutaneous flap in one patient). The morbidity and mortality were 22.4% and 3.4% respectively. Follow up was complete in 51 patients. Nineteen (37.2%) survived > or = 5 years. The absolute five year survival for N0 and N1 disease was 44.7% and 38.4%, respectively. No patients with N2 disease survived five years. CONCLUSIONS--In patients with carcinoma of the lung and chest wall invasion, combined pulmonary and thoracic wall resection offers the prospect of cure with minimal morbidity and mortality. The prognosis of patients with coexistent N2 disease remains poor. PMID:7570416

    Thirty-four consecutive patients with stage III testicular carcinomas were treated with vinblastine, 8 mg/m2 given in 2 fractions on day 1 and 2, followed by continuous intravenous administration of bleomycin, 15 mg/m2 in 1000 cc of 5% glucose and distilled water over a 24-hour period for 5 successive days beginning on day 2. This cycle was repeated every 28-35 days as toxicity permitted. Complete remission occurred in 18% and complete plus partial remission in 79%. Only 2 of 22 patients with advanced abdominal disease achieved a complete remission. After cytoreductive surgery the complete remission rate was increased to 39%. Median survival of complete responders at 3 years has not been reached, and it has been shown to be significantly superior to that of partial (p less than 0.01) and nonresponders (p less than 0.01). Toxic effects consisted mainly in severe leukopenia, stomatitis, adynamic ileum and osteoarticular pain. One drug-related death due to sepsis with agranulocytopenic fever was observed. Probably because of different patient selection, this report could not reproduce the results reported by Samuels et al. with equivalent drug dosage, but it was confirmed that this regimen is able to achieve a high overall response rate and a prolonged median survival in complete responders. The consistent success of this aggressive combination in inducing a high percentage of partial responses has opened the way for a better definition of the role of surgery for the treatment of advanced testicular carcinoma at out Institute.

    Attempts to cryopreserve fish embryos have been conducted over the past three decades, nevertheless successful cryopreservation protocol for long-term storage still remains elusive. Fish oocytes offer some advantages when compared to embryos, which may help in improving the chances of cryopreservation. In the present study, a series of cryo-solutions were designed and tested for their vitrifying ability using different devices (0.25 ml plastic straw, vitrification block and fibreplug(TM)). Toxicity of vitrification solutions was evaluated by assessing follicle membrane integrity with trypan blue staining. In addition, the effect of vitrification protocol on stage III zebrafish ovarian follicles was investigated by measuring the cytoplasmic ATP content and the mitochondrial distribution and activity using JC-1 probe and confocal microscopy. After vitrification, follicles showed membrane integrity of 59.9 ± 18.4% when fibreplug and V16 (1.5 M methanol + 4.5 M propylene glycol) solution were employed. When vitrified in V2 (1.5 M methanol + 5.5 M Me2SO) the membrane integrity decreased to 42.0 ± 21.0%. It was observed that follicles located in the middle of the fragments were more protected from injuries and some of them showed good morphological appearance two hours post-warming. Mitochondria integrity of granulosa cells layer was clearly damaged by the vitrification protocol and ATP level in the follicles declined significantly after warming. Vitrification of zebrafish follicles in ovarian tissue fragments and its effect at sub-cellular level is reported here for the first time. Information gained from this study will help in guiding development of optimal protocol for cryopreservation of fish oocytes. PMID:24513460

    Patients with early stage diffuse large B-cell lymphoma (DLBCL) receive RCHOP (rituximab cyclophosphamide, doxorubicin, vincristine, prednisone) alone or with involved field radiotherapy (IFRT). Anti-CD20 radioimmunotherapy (RIT) delivers radiation to microscopic sites outside of known disease. This phase II study aimed to achieve a functional complete response (CR) rate of ≥75% to RCHOP and (90) Yttrium-ibritumomab tiuxetan RIT. Patients with stages I/II DLBCL received 4-6 cycles of RCHOP followed by RIT [14·8 MBq/kg (0·4 mCi/kg)]; patients with positron emission tomographypositive sites of disease after RCHOP/RIT received 30 Gy IFRT. Of the 62 patients enrolled; 53 were eligible. 42% (22/53) had stage I/IE; 58% (31/53) stage II/IIE. After RCHOP, 79% (42/53) were in CR/unconfirmed CR. Forty-eight patients proceeded to RIT. One partial responder after RIT received IFRT and achieved a CR. The best response after RCHOP + RIT in all 53 patients was a functional CR rate of 89% (47/53; 95% confidence interval: 77-96%). With a median follow-up of 5·9 years, 7 (13%) patients have progressed and 4 (8%) have died (2 with DLBCL). At 5 years, 78% of patients remain in remission and 94% are alive. Chemoimmunotherapy and RIT is an active regimen for early stage DLBCL patients. Eighty-nine percent of patients achieved functional CR without the requirement of IFRT. This regimen is worthy of further study for early stage DLBCL in a phase III trial. PMID:25974212

    Over a decade since the discovery of EGFR mutation, and 6 years since prospective clinical trial data proved that routine molecular pathology tests improve survival in stage IV lung cancer, there is still debate whether to test patients with earlier stages of disease (stage I-III). As discoveries of targeted drugs for stage IV patients accelerate-prompting routine testing for ALK, ROS1, RET, BRAF V600E, and HER2, among others-there is an argument that all lung cancers should be genotyped for the purpose of classification, regardless of stage of disease. The counterargument is that because targeted drugs have only been validated for use in stage IV disease, these molecular tests need only be conducted at the time of disease recurrence. This review will describe current, practical applications of molecular pathology testing in early stage lung cancer, focusing on the immediate diagnostic, prognostic, and therapeutic implications for individual patient management. Meanwhile, large-scale clinical trials are underway to test targeted drugs as adjuvant therapies in patients with early stage disease. PMID:26215190

    Purpose: To examine the effectiveness of concomitant intra-arterial infusion chemotherapy (IAIC) using cisplatin (CDDP) with radiotherapy for Stage III squamous cell carcinoma of the cervix. Materials and Methods: We analyzed 29 cases of Stage III squamous cell carcinoma of the uterine cervix treated with radiotherapy and IAIC of CDDP from 1991 to 2006. External-beam therapy was given to the whole pelvis using four opposing parallel fields with an 18-MV linear accelerator unit. A central shield was used after 30-40 Gy with external whole-pelvic irradiation, and the total dose was 50 Gy. High-dose-rate brachytherapy was given with {sup 192}Ir microSelectron. The dose at Point A was 6 Gy per fraction, 2 fractions per week, and the total number of fractions was either 3 or 4. Two or three courses of IAIC were given concomitantly with CDDP 120 mg or carboplatin 300 mg. Results: We confirmed excellent medicine distribution directly by using computed tomographic angiography. The 5-year overall survival rate for Stage III patients was 62%, the cause-specific survival rate was 70%, and the local relapse-free survival rate was 89%. Local recurrence, distant metastasis, and occurrences of both were 7%, 38%, and 3%, respectively. The incidence of severe acute hematologic adverse reactions (Grade {>=}3) was 27% for all patients; however, all recovered without interruption of radiotherapy. Severe nonhematologic effects (Grade {>=}3) were 3%, including nausea and ileus. Only 1 patient's radiotherapy was interrupted for a period of 1 week because of ileus. Severe late complication rates (Grade {>=}3) for the bladder, rectum, and intestine were 3%, 3%, and 10%, respectively. Conclusion: A combination of IAIC and systemic chemotherapy should be considered to improve the prognosis of patients with Stage III squamous cell carcinoma of the cervix.

  3. Pegylated interferon alpha-2b as adjuvant treatment of Stage III malignant melanoma: an evidence-based review

    2010-01-01

    Introduction: Stage III melanoma, also referred to as regional metastatic melanoma, has five-year survival rates ranging between 40% and 78%. In order to reduce the likelihood of recurrence in this high-risk population, patients undergo resection of primary tumors and all involved nodal basins. Systemic therapy is being pursued in an effort to improve outcome data, but the best strategy has yet to be defined. Interferon alpha-2b remains to date the most promising approach available. Toxicities and intensive intravenous administration, unfortunately, are major concerns. An alternative is the use of interferon in its pegylated subcutaneous form. The aim of this research was to review the evidence for the use of pegylated interferon alpha-2b in Stage III malignant melanoma. Evidence review: ECOG 1684 was the pivotal trial that first demonstrated a statistically significant benefit in relapse-free and overall survival for adjuvant interferon alpha-2b in high-risk melanoma. Other larger studies, such as ECOG 1690, confirmed a relapse-free survival benefit but did not achieve statistical significance for overall survival. The first study of the pegylated form of interferon alpha-2b in Stage III melanoma, EORTC 18991, is reviewed here. This trial showed a statistically significant improvement in relapse-free survival but not overall survival. Encouraging data of potential equivalent efficacy, easier administration, and fewer Grade 3 and 4 adverse reactions compared with high-dose intravenous interferon raises the question of its potential role in Stage III melanoma in the adjuvant setting.

    The segregation and maintenance of eye-specific inputs in the dorsal lateral geniculate nucleus (dLGN) during early postnatal development requires the patterned spontaneous activity of retinal waves. In contrast to the development of the mouse, ferret eye-specific segregation is not complete at the start of stage III glutamatergic retinal waves, and the remaining overlap is limited to the C/C1 lamina of the dLGN. To investigate the role of patterned spontaneous activity in this late segregation, we disrupted retinal waves pharmacologically for 5 day windows from postnatal day (P) 10 to P25. Multi-electrode array recordings of the retina in vitro reveal that the cholinergic agonist epibatidine disrupts correlated retinal activity during stage III waves. Epibatidine also prevents the segregation of eye-specific inputs in vivo during that period. Our results reveal a novel role for cholinergic influence on stage III retinal waves as an instructive signal for the continued segregation of eye-specific inputs in the ferret dLGN. PMID:25794280

    BACKGROUND This study examined elderly stage II and III rectal cancer patients’ adjuvant chemoradiation therapy adherence, trends in adherence over time, and the relation of levels of adherence to mortality. METHODS The authors studied 2886 stage II and III rectal cancer patients who had surgical resection and who appeared in 1992–1999 linked SEER-Medicare claims data. The authors compared measures of adjuvant radiation and chemotherapy receipt and completion between stage II and III patients. Adjusted risk of cancer-related 5-year mortality was calculated by multivariate logistic regression for different levels of chemoradiation adherence among stage II and III patients. RESULTS Of the 2886 patients, 45.4% received both adjuvant radiation and chemotherapy. Stage III patients were more likely to receive chemoradiation than stage II patients. The receipt of chemoradiation by stage II patients increased significantly from 1992 to 1999. Stage III patients were more likely to complete radiation therapy (96.6%), chemotherapy (68.2%), and both modalities (67.5%) than stage II patients (91.5%, 49.8%, 47.6%, respectively). Only a complete course of both radiation and chemotherapy for both stage II (relative risk [RR] 0.74; 95% CI, 0.54, 0.97) and III (RR 0.80; 95% CI, 0.65, 0.96) decreased the adjusted 5-year cancer mortality risk compared with counterparts with no adjuvant therapy. CONCLUSIONS Even though stage II rectal cancer patients were less likely than stage III patients to receive and complete adjuvant chemoradiation, both patient groups in the general population had lower cancer-related mortality if they completed chemoradiation. These patients deserve support and encouragement to complete treatment. PMID:18189291

    Transarterial chemoembolization (TACE) has therapeutic effects in patients with unresectable hepatocellular carcinoma (HCC), but its impact on the cellular immune response during disease progression is largely unknown. Here we conducted a prospective study to evaluate the effect of TACE on immune status and to identify prognostic immune markers governing treatment success. In this study, 51 stage III HCC patients, 28 stage I HCC patients (TNM classification) and 20 healthy donors were enrolled. Flow cytometry and cytometric bead array were used to evaluate the circulating immune cell subsets, including CD4+ T cells (Th1, Th17 and Treg cells), CD8+ T cells, NK cells, and NKT cells, and plasma cytokines before TACE and 30 days after TACE. Interestingly, among those immune parameters, the frequency of circulating Th17 cells was higher in stage III HCC patients than in stage I HCC patients (P = 0.015) and healthy donors (P<0.001). Moreover, an increased frequency of circulating Th17 cells was observed 30 days after TACE (Th17D30) compared with the baseline level (P = 0.036). Kaplan-Meier analysis demonstrated that Th17D30 was positively associated with overall survival (OS; P = 0.007) and time to progression (TTP; P = 0.009). Multivariate Cox analysis revealed that Th17D30 was an independent prognostic factor for OS (HR = 0.317, P = 0.032) and TTP (HR = 0.304, P = 0.010). These results provide a potential prognostic marker for stage III HCC patients undergoing TACE and may be useful for identifying patients who can benefit from adjuvant immunotherapies. PMID:23565248

    We aimed to examine the frequency of treatment delays as well as the reasons and appropriateness of such delays in early stage colon cancer patients receiving adjuvant capecitabine by comparing data from pharmacy dispensing versus medical records. Patients diagnosed with stage II or III colon cancer from 2008 to 2012 and who received at least two cycle of adjuvant capecitabine were reviewed for treatment delays. Data from pharmacy dispensing and patient medical records were compared. Multivariate regression models were constructed to identify predictors of treatment delays. A total of 697 patients were analyzed: median age was 70 years (IQR 30-89), 394 (57%) were men, 598 (86%) reported Eastern Cooperative Oncology Group 0/1, and 191 (27%) had stage II disease. In this study cohort, 396 (57%) patients experienced at least 1 treatment delay during their adjuvant treatment. Upon medical record review, half of treatment delays identified using pharmacy administrative data were actually attributable to side effects, of which over 90% were considered clinically appropriate for patients to withhold rather than to continue the drug. The most prevalent side effects were hand-foot syndrome and diarrhea which occurred in 176 (44%) and 67 (17%) patients, respectively. Multivariate analysis revealed a statistically significant association between stage and inappropriate treatment delays whereby patients with stage II disease were more likely to experience drug noncompliance (OR 1.79, 95% CI: 1.27-2.53, P < 0.001) than those with stage III disease. Compliance with adjuvant capecitabine was reasonable. Adherence ascertained from pharmacy administrative data differs significantly from that obtained from medical records. PMID:27228415

    An important part of space launch vehicle mission planning for a planetary mission is the integrated analysis of guidance and performance dispersions for both booster and upper stage vehicles. For the Mars Observer mission, an integrated trajectory analysis was used to maximize the scientific payload and to minimize injection errors by optimizing the energy management of both vehicles. This was accomplished by designing the Titan III booster vehicle to inject into a hyperbolic departure plane, and the Transfer Orbit Stage (TOS) to correct any booster dispersions. An integrated Monte Carlo analysis of the performance and guidance dispersions of both vehicles provided sensitivities, an evaluation of their guidance schemes and an injection error covariance matrix. The polynomial guidance schemes used for the Titan III variable flight azimuth computations and the TOS solid rocket motor ignition time and burn direction derivations accounted for a wide variation of launch times, performance dispersions, and target conditions. The Mars Observer spacecraft was launched on 25 September 1992 on the Titan III/TOS vehicle. The post flight analysis indicated that a near perfect park orbit injection was achieved, followed by a trans-Mars injection with less than 2sigma errors.

    Purpose: Concerns have been raised about the potential for worse treatment outcomes because of dosimetric inaccuracies related to tumor motion and increased toxicity caused by the spread of low-dose radiation to normal tissues in patients with locally advanced non-small cell lung cancer (NSCLC) treated with intensity modulated radiation therapy (IMRT). We therefore performed a population-based comparative effectiveness analysis of IMRT, conventional 3-dimensional conformal radiation therapy (3D-CRT), and 2-dimensional radiation therapy (2D-RT) in stage III NSCLC. Methods and Materials: We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify a cohort of patients diagnosed with stage III NSCLC from 2002 to 2009 treated with IMRT, 3D-CRT, or 2D-RT. Using Cox regression and propensity score matching, we compared survival and toxicities of these treatments. Results: The proportion of patients treated with IMRT increased from 2% in 2002 to 25% in 2009, and the use of 2D-RT decreased from 32% to 3%. In univariate analysis, IMRT was associated with improved overall survival (OS) (hazard ratio [HR] 0.90, P=.02) and cancer-specific survival (CSS) (HR 0.89, P=.02). After controlling for confounders, IMRT was associated with similar OS (HR 0.94, P=.23) and CSS (HR 0.94, P=.28) compared with 3D-CRT. Both techniques had superior OS compared with 2D-RT. IMRT was associated with similar toxicity risks on multivariate analysis compared with 3D-CRT. Propensity score matched model results were similar to those from adjusted models. Conclusions: In this population-based analysis, IMRT for stage III NSCLC was associated with similar OS and CSS and maintained similar toxicity risks compared with 3D-CRT.

    Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST) is a genetic signature found in up to 60% of colorectal cancers (CRCs) that is caused by somatic dysfunction of the DNA mismatch repair (MMR) protein hMSH3. We have previously shown in vitro that recognition of 5-fluorouracil (5-FU) within DNA and subsequent cytotoxicity was most effective when both hMutSα (hMSH2-hMSH6 heterodimer) and hMutSβ (hMSH2-hMSH3 heterodimer) MMR complexes were present, compared to hMutSα > hMutSβ alone. We tested if patients with EMAST CRCs (hMutSβ defective) had diminished response to adjuvant 5-FU chemotherapy, paralleling in vitro findings. We analyzed 230 patients with stage II/III sporadic colorectal cancers for which we had 5-FU treatment and survival data. Archival DNA was analyzed for EMAST (>2 of 5 markers mutated among UT5037, D8S321, D9S242, D20S82, D20S85 tetranucleotide loci). Kaplan-Meier survival curves were generated and multivariate analysis was used to determine contribution to risk. We identified 102 (44%) EMAST cancers. Ninety-four patients (41%) received adjuvant 5-FU chemotherapy, and median follow-up for all patients was 51 months. Patients with EMAST CRCs demonstrated improved survival with adjuvant 5FU to the same extent as patients with non-EMAST CRCs (P<0.05). We observed no difference in survival between patients with stage II/III EMAST and non-EMAST cancers (P = 0.36). There is improved survival for stage II/III CRC patients after adjuvant 5-FU-based chemotherapy regardless of EMAST status. The loss of contribution of hMSH3 for 5-FU cytotoxicity may not adversely affect patient outcome, contrasting patients whose tumors completely lack DNA MMR function (MSI-H). PMID:25996601

    There are insufficient numbers of prognostic factors available for prediction of clinical outcome in patients with stage III malignant cutaneous melanoma, even when known adverse pathological risk factors, such as macrometastasis, number of lymph node metastases, and ulceration are taken into consideration. The aim of this study was therefore to identify additional prognostic factors to better predict patients with a high risk of relapse, thus enabling us to better determine the need for adjuvant treatment in stage III disease. An RNA oligonucleotide microarray study was performed on first regional lymph node metastases in 42 patients with stage III melanoma: 23 patients with short-term survival (≤ 13 months) and 19 with long-term survival (≥ 60 months), to identify genes associated with clinical outcome. Candidate genes were validated by real-time PCR and immunohistochemical analysis. Several gene ontology (GO) categories were highly significantly differentially expressed including glycolysis (GO: 0006096; P<0.001) and the pigment biosynthetic process (GO: 0046148; P<0.001), in which overexpression was associated with short-disease-specific survival. Three overexpressed glycolytic genes, GAPDHS, GAPDH, and PKM2, and two pigment-related genes, TYRP1 and OCA2, were selected for validation. A significant difference in GAPDHS protein expression between short- and long-term survivors (P=0.021) and a trend for PKM2 (P=0.093) was observed in univariate analysis. Positive expression of at least two of four proteins (GAPDHS, GAPDH, PKM2, TYRP1) in immunohistochemical analysis was found to be an independent adverse prognostic factor for disease-specific survival (P=0.011). Our results indicate that this prognostic panel in combination with established risk factors may contribute to an improved prediction of patients with a high risk of relapse. PMID:24128789

    Although now commonplace in contemporary cancer care, the systematic approach to classification of disease-specific cancers into a formalized staging system is a relatively modern concept. Overall, the goals of cancer staging are to characterize the status of cancer at a specific moment in time, risk stratify, facilitate prognostication, and inform clinical decision making. The revisions to the American Joint Committee on Cancer (AJCC) melanoma staging system over time reflect changes in our understanding of the biology of the disease. Since the 1st edition, where tumor thickness was defined anatomically by its relationship to the reticular or papillary dermis (Clark level) as well as tumor thickness (Breslow thickness), there have been significant strides in our use of clinicopathological variables to stratify low- versus high-risk patients. Management of the regional nodal basin has also changed dramatically over time, impacted by techniques such as lymphatic mapping and sentinel lymph node biopsy (SLNB) and changes in pathological evaluation of the regional lymph nodes. Additionally, stratification of distant metastases has evolved as survival outcomes have been shown to vary based upon anatomic site of metastases and serum lactate dehydrogenase levels. The variables in use in the current (7th edition) AJCC staging system are surrogate markers of biology with validated impact of survival outcomes. Going forward, it is likely that these and additional clinicopathological factors will be integrated with molecular and other correlates of melanoma tumor biology to further refine and personalize melanoma staging.

    The unconventional secretory pathway exports proteins that bypass the endoplasmic reticulum. In Saccharomyces cerevisiae, conditions that trigger Acb1 secretion via this pathway generate a Grh1 containing compartment composed of vesicles and tubules surrounded by a cup-shaped membrane and collectively called CUPS. Here we report a quantitative assay for Acb1 secretion that reveals requirements for ESCRT-I, -II, and -III but, surprisingly, without the involvement of the Vps4 AAA-ATPase. The major ESCRT-III subunit Snf7 localizes transiently to CUPS and this was accelerated in vps4Δ cells, correlating with increased Acb1 secretion. Microscopic analysis suggests that, instead of forming intraluminal vesicles with the help of Vps4, ESCRT-III/Snf7 promotes direct engulfment of preexisting Grh1 containing vesicles and tubules into a saccule to generate a mature Acb1 containing compartment. This novel multivesicular / multilamellar compartment, we suggest represents the stable secretory form of CUPS that is competent for the release of Acb1 to cells exterior. PMID:27115345

    Three hundred twenty patients were entered into GOG Protocol 63, a clinical-pathologic study of stage IIB, III, and IVA cervical carcinoma. Following the completion of FIGO staging prerequisites, patients had computerized tomography (CT), a lymph-angiogram (LAG), and an ultrasound (US) of the aortic area. If any study was positive, a cytologic or histologic evaluation by fine-needle aspiration or selective paraaortic lymphadenectomy was performed. Paraaortic node dissection was mandated for patients with negative extended staging studies. Results of extended staging evaluations were compared with histologic or cytologic results. Two hundred sixty-four patients were eligible and evaluable. One hundred sixty-seven patients (63%) were stage IIB, 89 (34%) were stage III, and 8 (3%) were stage IVA. Positive paraaortic nodes occurred in 21% of stage IIB, 31% of stage III, and 13% of stage IVA. LAG sensitivity was 79% with a specificity of 73%. Sensitivity of CT and US was 34 and 19%, respectively, with specificities of 96 and 99%, respectively. The frequency of false-negative results with LAG for patients with stage IIB disease was 6%. This decrease is consistent with a stable sensitivity and specificity. These findings suggest that a negative LAG may be adequate to eliminate surgical staging in subgroups with low risk of metastasis to the aortic nodes. Until new noninvasive testing methods are developed, LAG appears to be the most reliable noninvasive examination to evaluate spread of cervical cancer to aortic nodes. PMID:2227556

    Purpose: This prospective, nonrandomized study evaluates the effectiveness of epoetin alfa to maintain the hemoglobin levels at 12 to14 g/dL (optimal range for tumor oxygenation) during chemoradiation for Stage III esophageal cancer and its impact on overall survival (OS), metastatic-free survival (MFS), and locoregional control (LC). Methods and Materials: Ninety-six patients were included. Forty-two patients received epoetin alfa (150 IU/kg, 3 times a week) during radiotherapy, which was started at hemoglobin less than 13 g/dL and stopped at 14 g/dL or higher. Hemoglobin levels were measured weekly during RT. Results: Both groups were balanced for age, sex, performance status, tumor length/location, histology, grading, T-stage/N-stage, chemotherapy, treatment schedule, and hemoglobin before RT. Median change of hemoglobin was +0.3 g/dL/wk with epoetin alfa and -0.5 g/dL/wk without epoetin alfa. At least 60% of hemoglobin levels were 12 to 14 g/dL in 64% and 17% of the patients, respectively (p < 0.001). Patients who received epoetin alfa had better OS (32% vs. 8% at 2 years, p = 0.009) and LC (67% vs. 15% at 2 years, p = 0.001). MFS was not significantly different (42% vs. 18% at 2 years, p = 0.09). Conclusions: The findings suggest that epoetin alfa when used to maintain the hemoglobin levels at 12 to 14 g/dL can improve OS and LC of Stage III esophageal cancer patients.

    Colorectal cancer (CRC) is a heterogeneous disease with a high mortality rate and is still lacking an effective treatment. Our goal is to develop a robust prognosis model for predicting the prognosis in CRC patients. In this study, 871 stage II and III CRC samples were collected from six gene expression profilings. ColoFinder was developed using a 9-gene signature based Random Survival Forest (RSF) prognosis model. The 9-gene signature recurrence score was derived with a 5-fold cross validation to test the association with relapse-free survival, and the value of AUC was gained with 0.87 in GSE39582(95% CI [0.83-0.91]). The low-risk group had a significantly better relapse-free survival (HR, 14.8; 95% CI [8.17-26.8]; P < 0.001) than the high-risk group. We also found that the 9-gene signature recurrence score contributed more information about recurrence than standard clinical and pathological variables in univariate and multivariate Cox analyses when applied to GSE17536(p = 0.03 and p = 0.01 respectively). Furthermore, ColoFinder improved the predictive ability and better stratified the risk subgroups when applied to CRC gene expression datasets GSE14333, GSE17537, GSE12945and GSE24551. In summary, ColoFinder significantly improves the risk assessment in stage II and III CRC patients. The 9-gene prognostic classifier informs patient prognosis and treatment response. PMID:26989635

    Adipose tissue-derived hormones (adipocytokines), such as adiponectin, leptin, resistin and visfatin, and the pancreatic hormone insulin, have been suggested to play a role in carcinogenesis. we therefore hypothesized that the oncological treatment of breast cancer may alter the serum levels of these adipocytokines and insulin. In this study, we aimed to compare the serum levels of adipocytokines and insulin between the pre- and post-treatment period in patients with breast cancer. In this prospective study, 20 consecutive patients with stage II and III breast cancer underwent breast-conserving surgery or total mastectomy and/or axillary dissection. The patients received adjuvant chemotherapy and radiotherapy, if necessary. Blood samples were obtained during the preoperative period and postoperatively after completion of the adjuvant therapy. There was no statistically significant difference between the pre- and post-treatment levels of visfatin, adiponectin and leptin. However, the serum insulin and resistin levels and insulin resistance were found to be statistically significantly increased following treatment (P<0.05). Post-treatment resistin levels were positively correlated with insulin resistance (r=0.45, P<0.05). Therefore, oncological treatment of stage II and III breast cancer did not affect visfatin, adiponectin and leptin levels, but statistically significantly increased resistin levels and insulin resistance. In addition, the post-treatment resistin levels were positively correlated with insulin resistance, suggesting that resistin may be involved in the development of insulin resistance in breast cancer patients following treatment.

    This study aimed to evaluate the dosimetric outcomes of a base-dose-plan-compensation (BDPC) planning method for improving intensity-modulated radiotherapy (IMRT) for stage III lung cancer. For each of the thirteen included patients, three types of planning methods were applied to obtain clinically acceptable plans: (1) the conventional optimization method (CO); (2) a split-target optimization method (STO), in which the optimization objectives were set higher dose for the target with lung density; (3) the BDPC method, which compensated for the optimization-convergence error by further optimization based on the CO plan. The CO, STO and BDPC methods were then compared regarding conformity index (CI), homogeneity index (HI) of the target, organs at risk (OARs) sparing and monitor units (MUs). The BDPC method provided better HI/CI by 54%/7% on average compared to the CO method and by 38%/3% compared to the STO method. The BDPC method also spared most of the OARs by up to 9%. The average MUs of the CO, STO and BDPC plans were 890, 937 and 1023, respectively. Our results indicated that the BDPC method can effectively improve the dose distribution in IMRT for stage III lung cancer, at the expense of more MUs. PMID:27009235

    The Hippo pathway regulates tissue growth and cell fate. In colon cancer, Hippo pathway deregulation promotes cellular quiescence and resistance to 5-Fluorouracil (5-Fu). In this study, 14 polymorphisms in 8 genes involved in the Hippo pathway (MST1, MST2, LATS1, LATS2, YAP, TAZ, FAT4 and RASSF1A) were evaluated as recurrence predictors in 194 patients with stages II/III colon cancer treated with 5-Fu-based adjuvant chemotherapy. Patients with a RASSF1A rs2236947 AA genotype had higher 3-year recurrence rate than patients with CA/CC genotypes (56 vs 33%, hazard ratio (HR): 1.87; P=0.017). Patients with TAZ rs3811715 CT or TT genotypes had lower 3-year recurrence rate than patients with a CC genotype (28 vs 40%; HR: 0.66; P=0.07). In left-sided tumors, this association was stronger (HR: 0.29; P=0.011) and a similar trend was found in an independent Japanese cohort. These promising results reveal polymorphisms in the Hippo pathway as biomarkers for stages II and III colon cancer.The Pharmacogenomics Journal advance online publication, 15 September 2015; doi:10.1038/tpj.2015.64.

    In order to improve the prognosis of patients with localized non-Hodgkin's lymphomas (NHL) who are treated with radiotherapy (RT), a prospective controlled study utilizing a combined modality approach was carried out in patients with pathologic Stage I-II NHL. After treatment with regional RT, patients in complete remission were randomized to receive either no further therapy or 6 cycles of cyclophosphamide, vincristine and prednisolone (CVP). At 5 years from completion of irradiation, the relapse-free survival was 46.3% after RT and 72.1% after RT plus CVP (P=0.005). The corresponding findings for the overall survival calculated from the beginning of irradiation were 55.8 and 82.8% respectively (P=0.03). The favorable effects of adjuvant chemotherapy on relapse-free survival were statistically significant only in the subgroup with diffuse histology. In patients who relapsed after RT alone, the salvage therapy failed to induce a high incidence of second durable remission. Adjuvant chemotherapy is indicated to improve the curve rate in pathologic stage I-II NHL with diffuse histology when regional RT is utilized.

    Colorectal cancer (CRC) is a heterogeneous disease with a high mortality rate and is still lacking an effective treatment. Our goal is to develop a robust prognosis model for predicting the prognosis in CRC patients. In this study, 871 stage II and III CRC samples were collected from six gene expression profilings. ColoFinder was developed using a 9-gene signature based Random Survival Forest (RSF) prognosis model. The 9-gene signature recurrence score was derived with a 5-fold cross validation to test the association with relapse-free survival, and the value of AUC was gained with 0.87 in GSE39582(95% CI [0.83–0.91]). The low-risk group had a significantly better relapse-free survival (HR, 14.8; 95% CI [8.17–26.8]; P < 0.001) than the high-risk group. We also found that the 9-gene signature recurrence score contributed more information about recurrence than standard clinical and pathological variables in univariate and multivariate Cox analyses when applied to GSE17536(p = 0.03 and p = 0.01 respectively). Furthermore, ColoFinder improved the predictive ability and better stratified the risk subgroups when applied to CRC gene expression datasets GSE14333, GSE17537, GSE12945and GSE24551. In summary, ColoFinder significantly improves the risk assessment in stage II and III CRC patients. The 9-gene prognostic classifier informs patient prognosis and treatment response. PMID:26989635

    This study aimed to evaluate the dosimetric outcomes of a base-dose-plan-compensation (BDPC) planning method for improving intensity-modulated radiotherapy (IMRT) for stage III lung cancer. For each of the thirteen included patients, three types of planning methods were applied to obtain clinically acceptable plans: (1) the conventional optimization method (CO); (2) a split-target optimization method (STO), in which the optimization objectives were set higher dose for the target with lung density; (3) the BDPC method, which compensated for the optimization-convergence error by further optimization based on the CO plan. The CO, STO and BDPC methods were then compared regarding conformity index (CI), homogeneity index (HI) of the target, organs at risk (OARs) sparing and monitor units (MUs). The BDPC method provided better HI/CI by 54%/7% on average compared to the CO method and by 38%/3% compared to the STO method. The BDPC method also spared most of the OARs by up to 9%. The average MUs of the CO, STO and BDPC plans were 890, 937 and 1023, respectively. Our results indicated that the BDPC method can effectively improve the dose distribution in IMRT for stage III lung cancer, at the expense of more MUs. PMID:27009235

    The Hippo pathway regulates tissue growth and cell fate. In colon cancer, Hippo pathway deregulation promotes cellular quiescence and resistance to 5-Fluorouracil. In this study 14 polymorphisms in 8 genes involved in the Hippo pathway (MST1, MST2, LATS1, LATS2, YAP, TAZ, FAT4 and RASSF1A) were evaluated as recurrence predictors in 194 patients with stages II/III colon cancer treated with 5-Fu-based adjuvant chemotherapy. Patients with a RASSF1A rs2236947 AA genotype had higher 3-year recurrence rate than patients with CA/CC genotypes (56% vs 33%, HR: 1.87; p=0.017). Patients with TAZ rs3811715 CT or TT genotypes had lower 3-year recurrence rate than patients with a CC genotype (28% vs 40%; HR: 0.66; p=0.07). In left-sided tumors, this association was stronger (HR: 0.29; p=0.011) and a similar trend was found in an independent Japanese cohort. These promising results reveal polymorphisms in the Hippo pathway as biomarkers for stage II and III colon cancer. PMID:26370619

    The debate of treating stage III, large volume non-small cell lung cancer (NSCLC) with definitive chemo-radiotherapy continues to be waged. A physically fit patient, having large volume and unresectable disease is the ideal candidate for this treatment approach. The ability of this patient population to successfully complete, and thereby benefit from an aggressive, combined treatment to improve local control and survival, drives the recommendation of treating oncologists for this approach. Until a phase III trial proves otherwise, concurrent chemo-radiotherapy will remain the ideal treatment for fit patients having large volume unresectable stage III NSCLC. PMID:27186513

    New therapies for melanoma have yielded promising results, but their application is limited because of serious side-effects and only moderate impact on patient survival. Vaccine therapies may offer some hope by targeting tumor-specific responses, considering the immunogenic nature of melanomas. To investigate the safety profile and efficiency of a xenogeneic cell-based vaccine therapy in stage III melanoma patients and evaluate the survival rate in treated patients. Twenty-seven stage III melanoma patients were immunized with a lyophilized xenogeneic polyantigenic vaccine (XPV) prepared from murine melanoma B16 and carcinoma LLC cells. Neither grade III/IV toxicities, nor clinically significant changes in blood and biochemical parameters were noted after an induction course of 10 XPV subcutaneous immunizations. No laboratory or clinical signs of systemic autoimmunity were documented. Following 10 vaccinations, a relative increase in the numbers of circulating memory CD4+CD45RO+ T cells (but not CD8+ CD45RO+ T cells) was observed. Peripheral blood mononuclear cells obtained from XPV-treated patients demonstrated increased proliferative responses to human BRO melanoma-associated antigens and marked increases in serum levels of IFN-γ and IL-8. Serum levels of TNF-α, IL-4 and IL-6 were not affected. The overall five-year survival rate in the treated patients was significantly higher than that in 27 control patients with matched clinical and prognostic characteristics (55% vs 18%). XPV-based immunotherapy could be maximally effective when started as early as possible before or after surgical excision of the primary tumor and local metastases, i.e. when tumor-mediated suppressive effects on immunity are minimal.

    Compressor operation at low air flows for a given speed is limited by unstable flow conditions, commonly called surge. An investigation of surge in centrifugal compressors (reference 1) showed that the pulsation of pressures and velocities occurred when the slope of the compressor characteristic curve was positive and that the magnitude and frequency, as well as the incidence of surge, depended on the capacity and resistance of the total system. Although the theory presented in reference 1 is applicable to axial-floe compressors, little experimental information is available on the surge characteristics of the individual stages of axial-flow compressors, or on the variation of the surge characteristics with operating conditions. During the investigation to determine the performance of the X24C-2 compressor (references 2 and 3), instrumentation was added to study the surge characteristics and to determine the effect of speed and inlet pressure on the frequency, amplitude, and phase relation of the pressure pulsations behind each stage.

    Purpose: The use of prophylactic cranial irradiation (PCI) in small cell lung cancer (SCLC) with surgical resection has not been fully identified. This study undertook to assess the factors affecting the risk of brain metastases in patients with stage I-III SCLC after surgical resection. The implications of PCI treatment for these patients are discussed. Methods and Materials: One hundred twenty-six patients treated with surgical resection for stage I-III SCLC from January 1998-December 2009 were retrospectively analyzed to elucidate the risk factors of brain metastases. Log-rank test and Cox regression model were used to determine the risk factors of brain metastases. Results: The median survival time for this patient population was 34 months, and the 5-year overall survival rate was 34.9%. For the whole group, 23.0% (29/126) of the patients had evidence of metastases to brain. Pathologic stage not only correlated with overall survival but also significantly affected the risk of brain metastases. The 5-year survival rates for patients with pathologic stages I, II, and III were 54.8%, 35.6%, and 14.1%, respectively (P=.001). The frequency of brain metastases in patients with pathologic stages I, II, and III were 6.25% (2/32), 28.2% (11/39), and 29.1% (16/55) (P=.026), respectively. A significant difference in brain metastases between patients with complete resection and incomplete resection was also observed (20.5% vs 42.9%, P=.028). The frequency of brain metastases was not found to be correlated with age, sex, pathologic type, induction chemotherapy, adjuvant chemotherapy, or adjuvant radiation therapy. Conclusions: Stage I SCLC patients with complete resection had a low incidence of brain metastases and a favorable survival rate. Stage II-III disease had a higher incidence of brain metastases. Thus, PCI might have a role for stage II-III disease but not for stage I disease.

    The treatment of patients with Stage I-II seminoma has changed considerably in the past decade, and in November 2009, an International Consensus meeting was held under the sponsorship of the Union for International Cancer Control (UICC), Société Internationale d'Urologie (SIU), and International Consultation on Urological Diseases (ICUD) to review recent updates in the published data and develop international consensus guidelines on the treatment of this group of patients. In Stage I disease, the consensus conference recommended that patients should be informed of all treatment options, including the potential benefits and side effects of each treatment. It was agreed that this discussion should include a review of the possible salvage treatment effects. In addition, in patients willing and able to adhere to a surveillance program, this should be considered the management option of choice (assuming facilities are available for suitable monitoring). For Stage IIA disease, the consensus conference recommended that radiotherapy should be considered the standard treatment in the absence of contraindications. For Stage IIB disease, chemotherapy or radiotherapy were considered reasonable treatment approaches, and for Stage IIC disease, chemotherapy should be considered the standard treatment approach. For patients with a residual mass after chemotherapy, the consensus conference noted that patients with masses <3 cm in diameter could likely be safely observed, and patients with residual masses >3 cm in diameter could be considered for immediate surgery or close observation. It was also noted that surgery in this setting is technically challenging and could be associated with greater morbidity than in patients with nonseminomatous tumors. PMID:21986223

    BACKGROUND The American Joint Committee on Cancer’s (AJCC) 7th edition cancer staging manual reflects recent changes in cancer care practices. This report assesses changes from the AJCC 6th to the AJCC 7th edition stage distributions and the quality of site-specific factors (SSFs). METHODS Incidence data for renal parenchyma and pelvis and ureter cancers from 18 Surveillance, Epidemiology, and End Results (SEER) registries were examined, including staging trends during 2004–2010, stage distribution changes between the AJCC 6th and 7th editions, and SSF completeness for cases diagnosed in 2010. RESULTS From 2004 to 2010, the percentage of stage I renal parenchyma cancers increased from 50% to 58%, whereas stage IV and unknown stage cases decreased (18% to 15%, and 10% to 6%, respectively). During this period, the percentage of stage 0a renal pelvis and ureter cancers increased from 21% to 25%, and stage IV and unknown stage tumors decreased (20% to 18%, and 7% to 5%, respectively). Stage distributions under the AJCC 6th and 7th editions were about the same. For renal parenchymal cancers, 71%–90% of cases had known values for 6 required SSFs. For renal pelvis and ureter cancers, 74% of cases were coded as known for SSF1 (WHO/ISUP grade) and 47% as known for SSF2 (depth of renal parenchymal invasion). SSF values were known for larger proportions of cases with reported resections. CONCLUSIONS Stage distributions between the AJCC 6th and 7th editions were similar. SSFs were known for more than two-thirds of cases, providing more detail in the SEER database relevant to prognosis. PMID:25412394

    Our aim was to evaluate the efficacy and safety of cisplatin with pemtrexed or vinorelbine and concurrent late course accelerated hyperfractionated radiotherapy (LCAHRT). Patients with unresectable stage III non-small-cell lung cancer (NSCLC) were randomly assigned to two regimens. The experimental (PP) arm included cisplatin, pemtrexed and concurrent LCAHRT based on bilateral lung V20 = 33%. The control (NP) arm used cisplatin, vinorelbine with the same radiotherapy protocol. The primary endpoint was overall survival. Median survival times were 26.0 months (95% CI 23.2 to 28.7 months) and 28.5 months (95% CI 17.1 to 39.9 months) for the NP and PP arms, respectively (P = 0.26). Median progression-free survival was 12.5 months and 17.5 months in the NP and PP arms (P = 0.07). In both arms of the study, there were no differences in overall survival between patients with squamous and nonsquamous NSCLC. The incidences of grade 3 or 4 toxicity were higher in NP than PP arm. With concurrent LCAHRT, pemetrexed/cisplatin was equally as efficacious as vinorelbine/cisplatin, but showed a more favorable toxicity profile. PMID:26761213

    Background: Osteoarthritis often affects the joint bilaterally, and the single-stage (SS) unicompartmental knee arthroplasty (UKA) is advantageous in terms of a single anesthesia administration, a short hospital stay, lower medical costs, and enhanced patient convenience. However, the complication risk of SS UKA continues to be debated. The aim of this article was to evaluate the clinical effectiveness, complications, and functional recovery of SS and two-stage (TS) UKA. Methods: From January 2008 to December 2013, we compared a series of 36 SS UKA with 45 TS UKA for osteoarthritis. The mean age was 65.4 years (range: 55–75 years). The mean body mass index was 25.2 kg/m2 (range: 22–29 kg/m2). The pre- and post-operative Oxford Knee Scores (OKSs), complications, operative times, tourniquet times, the amount of drainage, and hemoglobin (Hb) were evaluated. The Chi-square test, Fisher's exact test, and paired and grouped t-tests were used in this study. Results: The mean follow-up was 50 months. No complications of death, fat embolism, deep vein thrombosis, and prosthetic infection were reported. Patients who underwent SS UKA had a shorter cumulative anesthesia time (113.5 vs. 133.0 min, P < 0.01). There were no significant variations between the values of the mean tourniquet time, the amount of drainage, pre- and post-operative Hb in the different groups. No patient required a blood transfusion. No statistical differences were found in the complications between two groups (P > 0.05). At the final follow-up, the mean OKS improved from 39.48 ± 5.69 to 18.83 ± 3.82 (P < 0.01), with no statistical differences between the two groups (P > 0.05). Patients who underwent SS UKA had a faster recovery. Conclusions: The single-staged UKA offers the benefits of a single anesthesia administration, reduced total anesthetic time, decreased overall rehabilitation time, and absence of an increase in perioperative mortality or complications compared with the TS bilateral UKA

    The patient has been one of the focal points of the process followed to design, implement, and evaluate an integrated informatics curriculum in a baccalaureate nursing program. This paper describes the third stage of a process to design the informatics nursing courses. A challenge is to structure the nursing informatics curriculum so as to enhance the patient care process. A number of strategies were used to focus the curriculum, students, and faculty around the patient. The basic components of the framework are information, technology, and clinical care process. The clinical care process which emphasizes the patient is an inherent part of the conceptual framework in all aspects of the curriculum. Therefore the faculty has ensured a blend of information, technology, and the clinical care process throughout the curriculum. PMID:8130578

    Purpose: To identify a cohort of women treated with neoadjuvant chemotherapy and mastectomy for whom postmastectomy radiation therapy (PMRT) may be omitted according to the projected risk of local-regional failure (LRF). Methods and Materials: Seven breast cancer physicians from University of California cancer centers created 14 hypothetical clinical case scenarios, identified, reviewed, and abstracted the available literature (MEDLINE and Cochrane databases), and formulated evidence tables with endpoints of LRF, disease-free survival, and overall survival. Using the American College of Radiology appropriateness criteria methodology, appropriateness ratings for postmastectomy radiation were assigned for each scenario. Finally, an overall summary risk assessment table was developed. Results: Of 24 sources identified, 23 were retrospective studies from single institutions. Consensus on the appropriateness rating, defined as 80% agreement in a category, was achieved for 86% of the cases. Distinct LRF risk categories emerged. Clinical stage II (T1-2N0-1) patients, aged >40 years, estrogen receptor-positive subtype, with pathologic complete response or 0-3 positive nodes without lymphovascular invasion or extracapsular extension, were identified as having {<=}10% risk of LRF without radiation. Limited data support stage IIIA patients with pathologic complete response as being low risk. Conclusions: In the absence of randomized trial results, existing data can be used to guide the use of PMRT in the neoadjuvant chemotherapy setting. Using available studies to inform appropriateness ratings for clinical scenarios, we found a high concordance of treatment recommendations for PMRT and were able to identify a cohort of women with a low risk of LRF without radiation. These low-risk patients will form the basis for future planned studies within University of California Athena Breast Health Network.

    A total of 151 patients with previously untreated Hodgkin's disease, clinical stages III-IV A & B, were randomized to receive CVPP for 6 cycles, or CVPP plus RT 3000 cGy to previously involved areas between the 3rd and 4th cycles. CVPP consists of cyclophosphamide 600 mg/m2/i.v., vinblastine 6 mg/m2/i.v. on day 1, procarbazine 100 mg/m2/p.o. and prednisone 40 mg/m2/p.o. on days 1 to 14. Both groups displayed similar clinical characteristics at diagnosis. Sixty-six were treated with CVPP + RT (52 St III and 14 St IV) and 85 with CVPP alone (68 St III and 17 St IV). Complete remission was obtained in 57 (86%) of 66 patients who received CVPP plus RT, and in 62 (73%) of 85 patients treated with CVPP. Five and sixteen patients, respectively, achieved partial responses, while 2 in each group died during treatment. At 7 years, duration of complete remission and failure-free survival were: 51% and 45% for those treated with CVPP plus RT, and 23% and 21% with CVPP alone (p = 0.0150 and P = 0.0016, respectively). Overall survival at 7 years was 71% and 58%, respectively (p = 0.1488). A dose analysis performed in 84 pts showed that 91% and 88% received full protocol doses of CPM and PCZ, respectively, in the CVPP + RT group, and 95% and 94% for CVPP. The WBC nadir was 3.5 and 3.7 x mm3, respectively. Of 25 pts on CVPP + RT who relapsed, 9 are now disease-free, 5 are alive with disease and 11 have died, and with CVPP, of 37 relapsing pts, 18 are disease-free, 5 are alive with disease and 14 are dead.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1498073

    AIM: To prospectively determine the safety and tolerability of oral L-selenomethionine (SLM) with concurrent chemoradiation (CCRT) for Stage III non-small cell lung cancer (NSCLC) and estimate if the incidence and/or severity of adverse events could be reduced by its use. METHODS: Sixteen patients with stage III NSCLC were accrued to this single arm, phase II study. CCRT consisted of radiation given at 2 Gy per fraction for 30-33 fractions, 5 d per week with concurrent weekly IV paclitaxel 50 mg/m2 followed by carboplatin dosed at an area under the time-concentration curve of 2. SLM was dosed in a loading phase at 4800 μg twice daily for one week prior to CCRT followed by once daily dosing during treatment. RESULTS: No selenium-related toxicity was observed. Analysis revealed grade 3 or higher esophagitis in 3 of 16 patients (19%), pneumonitis in 0, leukopenia in 2 (12.5%), and anemia in 1 (6%); the latter two were significantly reduced when compared to the protocol-stated expected rate of 35% (P = 0.045 for leukopenia, and P < 0.01 for anemia). Median overall survival was 14.9 mo and median failure-free survival was 9 mo (95%CI: 3.3-21.5). CONCLUSION: There may be some protective benefit of selenium in the setting of CCRT for inoperable NSCLC. The data suggests decreased rates of myelosuppression when compared to similarly-treated historical and contemporary controls. Further evaluation of selenium in this setting may be warranted.

    Purpose: To describe the anatomic distribution of regionally recurrent disease in patients with stage III melanoma in the axilla after curative-intent surgery with and without adjuvant radiation therapy. Methods and Materials: A single-institution, retrospective analysis of a prospective database of 277 patients undergoing curative-intent treatment for stage III melanoma in the axilla between 1992 and 2012 was completed. For patients who received radiation therapy and those who did not, patterns of regional recurrence were analyzed, and univariate analyses were performed to assess for potential factors associated with location of recurrence. Results: There were 121 patients who received adjuvant radiation therapy because their clinicopathologic features conferred a greater risk of regional recurrence. There were 156 patients who received no radiation therapy. The overall axillary control rate was 87%. There were 37 patients with regional recurrence; 17 patients had received adjuvant radiation therapy (14%), and 20 patients (13%) had not. The likelihood of in-field nodal recurrence was significantly less in the adjuvant radiation therapy group (P=.01) and significantly greater in sites adjacent to the axilla (P=.02). Patients with high-risk clinicopathologic features who did not receive adjuvant radiation therapy also tended to experience in-field failure rather than adjacent-field failure. Conclusions: Patients who received adjuvant radiation therapy were more likely to experience recurrence in the adjacent-field regions rather than in the in-field regions. This may not simply reflect higher-risk pathology. Using this data, it may be possible to improve outcomes by reducing the number of adjacent-field recurrences after adjuvant radiation therapy.

    The aim of the study was to evaluate the effectiveness of combined treatment of locally advanced lung cancer with the use of neoadjuvant chemotherapy and surgery with the use of pre- and intraoperative photodynamic therapy. 20 patients with IIIa (n=7) and IIIb (n=13) stage of non-small cell lung carcinoma were included. At the time of diagnosis the surgical treatment was decided to abstain because of the trachea invasion in 9 patients, wide mediastinal invasion in 2 patients and contralateral mediastinal lymph nodes metastases in 2 patients; pneumonectomy was not possible due to the poor respiratory function in 7 patients. Neoadjuvant therapy included 3 courses of chemotherapy and endobronchial photodynamic therapy. During the operation, along with the lung resection (pneumonectomy - 15, lobectomy - 5), photodynamic therapy of the resection margins were carried out. No adjuvant treatment was done. Preoperative treatment led to partial regress of the disease in all cases; the goal of surgery was the complete tumor removal. No complications of the photodynamic therapy were observed. 18 surgical interventions were radical and two non-complete microscopically (R1). Postoperative morbidity was 20%, one patient died due to massive gastrointestinal bleeding. The average follow-up period was 18 months: 19 patients were alive, of them 18 with no signs of the disease recurrence. The first experience of the combined use of neoadjuvant chemotherapy and surgery with pre- and intraoperative photodynamic therapy demonstrates safety and efficacy of the suggested treatment tactics.

    Thirty patients with Stage III non-small cell lung cancer were entered on a trial to evaluate the feasibility of combined radiation and concomitant 5-fluorouracil infusion. Patients had received prior debulking surgery (nine), induction chemotherapy (16), or no therapy (five). Radiation employed standard fractionation (180-200 rad/day) administered to a median cumulative dose of 5500 rad (range, 4500-6200 rad). 5-Fluorouracil was infused 24 hours per day throughout the period of radiation at a dose of 300 mg/m2/day for a median of 42 days (range, 28-56 days). Radiation complications included pneumonitis three of 30 (10%) and esophagitis (27%). Chemotherapy complications included stomatitis, two of 27 (7%), and hand-foot syndrome, three of 30 (10%). Treatment interruptions were necessary in six of 30 (20%) and four of 30 required parenteral nutrition. At a median follow-up of 12 months 26/30 (87%) maintained local control and eight had distant metastases (three of whom presented with Stage IV disease). 5-Fluorouracil delivered continuously throughout standard fractionation radiation to high cumulative doses is feasible and practical. Comparative clinical trials of the various combined radiation and chemotherapy schedules employed are in order. One additional clinical observation was the identification of six of 30 (20%) with brain metastases at presentation or after 12 months, all of whom had adenocarcinoma histologic subtype.

    Background and Objective Studies examining the prognostic value of the BRAF mutation on relapse-free survival (RFS), disease-free survival (DFS) and overall survival (OS) in stage II/III colorectal cancer (CRC) patients receiving curative resection and adjuvant chemotherapy so far showed discrepant results. Therefore, a meta-analysis of relevant studies was performed for clarification. Methods Randomized trials of stage II/III colorectal cancer treated with curative resection followed by adjuvant chemotherapy were selected to conduct a meta-analysis. The necessary descriptive and statistical information such as hazard ratios (HRs) and 95% confidence intervals (CIs) were derived from published survival data. Results Seven phase III randomized clinical trials (RCTs) including 1,035 BRAF mutation stage II/III CRC patients receiving curative resection and adjuvant chemotherapy were analyzed. Overall, BRAF mutation resulted in poorer OS (HR = 1.42, 95% CI: 1.25–1.60; P < 0.00001), and poorer DFS (HR = 1.26, 95% CI: 1.07–1.48, P = 0.006) compared with BRAF wild-type CRC. The prognostic role on RFS could not be elucidated in the meta-analysis because of limited data. Conclusions BRAF mutation was significantly related with shorter DFS and OS among stage II/III CRC patients receiving adjuvant chemotherapy after curative resection. Its prognostic role for RFS needs to be further analyzed when more data is available. PMID:27138801

    Purpose We report long-term disease control, survival, and toxicity for patients with locally advanced non-small cell lung cancer prospectively treated with concurrent proton therapy and chemotherapy on a nonrandomized case-only obervational study. Methods All patients received passive-scatter proton therapy, planned with 4D-CT–based simulation; all received proton therapy concurrent with weekly chemotherapy. Endpoints were local and distant control, disease-free survival (DFS), and overall survival (OS). Results The 134 patients (21 stage II, 113 stage III; median age 69 years) had a median gross tumor volume (GTV) of 70 cm3 (range, 5-753 cm3); 77 patients (57%) received 74 Gy(RBE), and 57 (42% received 60–72 Gy(RBE) (range, 60-74.1 Gy(RBE)). At a median follow-up time of 4.7 years, median OS times were 40.4 months (stage II) and 30.4 months (stage III). Five-year DFS rates were 17.3% (stage II) and 18.0% (stage III). OS, DFS, and local and distant control rates at 5 years did not differ by disease stage. Age and GTV were related to OS and DFS. Toxicity was tolerable, with 1 grade 4 esophagitis and 16 grade 3 events (2 pneumonitis, 6 esophagitis, 8 dermatitis). Conclusion This report of outcomes after proton therapy for 134 patients indicated that this regimen produced excellent OS with tolerable toxicity. PMID:26028228

    Background Whether postoperative radiotherapy (PORT) is effective for reducing the recurrence risk in patients who received complete resection of the stage II or III thymic tumors has not been determined. A meta-analysis was performed by combining the results of all available controlled trials. Methods PubMed, Cochrane’s Library, and the Embase databases were searched for studies which compared the recurrence data for patients with complete resection of the stage II or III thymic tumors assigned to an observing group, or a PORT group. A random effect model was applied to combine the results. Results Nineteen studies, all designed as retrospective cohort studies were included. These studies included 663 patients of PORT group and 617 patients of observing group. The recurrence rate for the patients in PORT group and observing group were 12.4% and 11.5%, respectively. Results of our study indicated that PORT has no significant influence on recurrent risk in patients with stage II or III thymic tumor after complete resection (odds ratio 1.02, 95% confidence interval 0.55–1.90, P=0.96). When stratified by stages, our meta-analyses did not indicate any significant effects of PORT on recurrent outcomes in either the stage II or the stage III patients. Moreover, subsequent analysis limited to studies only including patients with thymoma or thymic carcinoma also did not support the benefits of PORT on recurrent outcomes. Conclusion Although derived from retrospective cohort studies, current evidence did not support any benefit of PORT on recurrent risk in patients with complete resection of the stage II or III thymic tumors.

    The aim of this study was to determine whether pretreatment status of thymidine phosphorylase (TP), and hypoxia-inducible factor alpha (HIF-1α) could predict pathologic response to neoadjuvant chemoradiation therapy with oxaliplatin and capecitabine (XELOXART) and outcomes for clinical stage II/III rectal cancer patients. A total of 180 patients diagnosed with clinical stage II/III rectal cancer received XELOXART. The status of TP, and HIF-1α were determined in pretreatment biopsies by immunohistochemistry (IHC). Tumor response was assessed in resected regimens using the tumor regression grade system and TNM staging system. 5-year disease free survival (DFS) and 5-year overall survival (OS) were evaluated with the Kaplan-Meier method and were compared by the log-rank test. Over expression of TP and low expression of HIF-1α were associated with pathologic response to XELOXART and better outcomes (DFS and OS) in clinical stage II/III rectal cancer patients (P < 0.05). Our result suggested that pretreatment status of TP and HIF-1α were found to predict pathologic response and outcomes in clinical stage II/III rectal cancer received XELOXART. Additional well-designed, large sample, multicenter, prospective studies are needed to confirm the result of this study. PMID:26617778

    This paper presents a summary of the evidence review group report into the clinical effectiveness and cost-effectiveness of rituximab for the treatment of relapsed or refractory stage III or IV follicular non-Hodgkin's lymphoma (NHL), in accordance with the licensed indication, based upon the evidence submission from Roche Products Ltd to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The submitted clinical evidence included two randomised controlled trials [European Organisation for Research and Treatment of Cancer (EORTC) and German Low Grade Lymphoma Study Group - Fludarabine, Cyclophosphamide and Mitoxantrone and (GLSG-FCM)] comparing the clinical effects of chemotherapy with or without rituximab in the induction of remission at first or second relapse and the clinical benefits of rituximab maintenance therapy versus the NHS's current clinical practice of observation for follicular lymphoma (FL) patients. Both trials showed that in patients with relapsed FL the addition of rituximab to chemotherapy induction treatment increased overall response rates. Furthermore, rituximab maintenance therapy increased the median length of remission when compared with observation only. Safety data from the two trials showed that while the majority of patients reported some adverse events, the number of patients withdrawing from treatment in the EORTC trial was low, with rates not being reported for the GLSG-FCM trial. The most commonly reported adverse events were blood/bone marrow toxicity, skin rashes and allergies. The ERG reran the manufacturer's economic model after altering several of the assumptions and parameter values in order to recalculate the cost-utility ratios, quality-adjusted life-years (QALYs) and estimates of benefits. The manufacturer reported that maintenance therapy with rituximab was cost-effective compared with observation against commonly applied thresholds, with an incremental

    Purpose: To determine whether pretreatment CT texture features can improve patient risk stratification beyond conventional prognostic factors (CPFs) in stage III non-small cell lung cancer (NSCLC). Methods and Materials: We retrospectively reviewed 91 cases with stage III NSCLC treated with definitive chemoradiation therapy. All patients underwent pretreatment diagnostic contrast enhanced computed tomography (CE-CT) followed by 4-dimensional CT (4D-CT) for treatment simulation. We used the average-CT and expiratory (T50-CT) images from the 4D-CT along with the CE-CT for texture extraction. Histogram, gradient, co-occurrence, gray tone difference, and filtration-based techniques were used for texture feature extraction. Penalized Cox regression implementing cross-validation was used for covariate selection and modeling. Models incorporating texture features from the 33 image types and CPFs were compared to those with models incorporating CPFs alone for overall survival (OS), local-regional control (LRC), and freedom from distant metastases (FFDM). Predictive Kaplan-Meier curves were generated using leave-one-out cross-validation. Patients were stratified based on whether their predicted outcome was above or below the median. Reproducibility of texture features was evaluated using test-retest scans from independent patients and quantified using concordance correlation coefficients (CCC). We compared models incorporating the reproducibility seen on test-retest scans to our original models and determined the classification reproducibility. Results: Models incorporating both texture features and CPFs demonstrated a significant improvement in risk stratification compared to models using CPFs alone for OS (P=.046), LRC (P=.01), and FFDM (P=.005). The average CCCs were 0.89, 0.91, and 0.67 for texture features extracted from the average-CT, T50-CT, and CE-CT, respectively. Incorporating reproducibility within our models yielded 80.4% (±3.7% SD), 78.3% (±4.0% SD), and 78

    Therapeutic options for locoregional esophageal cancer (EC) include primary surgery, neoadjuvant or definitive chemoradiation and systemic chemotherapy. The role of surgery in these multimodal strategies has recently been debated and definitive chemoradiation is being offered as an alternative to surgery at many centers. We examined our results with multimodal therapy and surgery in this patient population. We conducted a retrospective analysis of 172 patients with locoregional (AJCC stages I-III) EC treated at RPCI between February 14, 1990 and September 20, 2002. Median age was 65 years (range, 36-95); there were 136 male patients. There were 100 regional (stages IIB-III), 69 local (stages I-IIA) and three in situ cases. Initial therapy was either combined modality (n = 122) or single modality (surgery) (n = 50). There was 0%, 30-day, postoperative mortality. Median survival for all patients was 25.3 months and was better for local stage with surgery alone (75 months) than with neoadjuvant (35.7 months) or definitive chemoradiation (19.1 months, P < 0.001). Survival for patients with regional disease treated with surgery alone, neoadjuvant or definitive chemoradiation was 21.5, 24.4 and 11.8 months, respectively (P = not significant). The associations of prognostic factors with overall survival were evaluated using Cox proportional hazards regression analysis and 2-sided Wald's chi-square test. On multivariate analysis, carefully selected patients treated with surgery alone had better outcomes compared with those treated with definitive chemoradiation (P < 0.001). Patients with locoregional esophageal cancer who are eligible for surgical resection either alone or as a part of multimodal therapy may have better outcomes than those treated with non-surgical approaches.

    Aim. To investigate the correlation between PPP1R12A gene copy number and clinical outcomes of oxaliplatin-based regimen in stage III colorectal cancer (CRC). Methods. A total of 139 paraffin-embedded tissue samples of stage III CRC patients who received oxaliplatin-based treatment after radical surgery were recruited. Genomic DNA was extracted and purified from paraffin-embedded sections. Quantitative PCR methods were used to detect the relative copy number (RCN) of PPP1R12A. Results. Statistical analysis demonstrated that low PPP1R12A RCN was associated with poor RFS (HR = 2.186, 95% CI: 1.293–3.696; P = 0.003) and OS (HR = 2.782, 95% CI: 1.531–5.052; P < 0.001). Additionally, when patients were stratified according to subgroups of stage III and tumor location, poor RFS and OS were also observed in the low PPP1R12A RCN group with significance (RFS: IIIB HR = 2.870, P < 0.001; colon HR = 1.910, P = 0.037; OS: IIIB HR = 3.527, P < 0.001; IIIC HR = 2.662, P = 0.049; rectum HR = 4.229, P = 0.002). Conclusion. Our findings suggest the copy number of PPP1R12A can independently predict recurrence and overall survival of stage III colorectal cancer patients receiving oxaliplatin-based chemotherapy.

    SummaryThis study examines the performance of the Next Generation Weather Radar (NEXRAD) Multisensor Precipitation Estimator (MPE) and Stage III precipitation products, using a high-density rain gauge network located on the Upper Guadalupe River Basin of the Texas Hill Country. As point-area representativeness error of gauge rainfall is a major concern in assessment of radar rainfall estimation, this study develops a new method to automatically select uniform rainfall events based on coefficient of variation criterion of 3 by 3 radar cells. Only gauge observations of those uniform rainfall events are used as ground truth to evaluate radar rainfall estimation. This study proposes a new parameter probability of rain detection (POD) instead of the conditional probability of rain detection (CPOD) commonly used in previous studies to assess the capability that a radar or gauge detects rainfall. Results suggest that: (1) gauge observations of uniform rainfall better represent ground truth of a 4 × 4 km 2 radar cell than non-uniform rainfall; (2) the MPE has higher capability of rain detection than either gauge-only or Stage III; (3) the MPE has much higher linear correlation and lower mean relative difference with gauge measurements than the Stage III does; (4) the Stage III tends to overestimate precipitation (20%), but the MPE tends to underestimate (7%).

    The aim of the study was to determine if biomarker expression could help discriminate between short-term and long-term survivors in women with advanced ovarian cancer. Fifty-one patients with stage III ovarian cancer were selected for the study, which included 28 short-term survivors (death from ovarian cancer within 18 months) and 23 long-term survivors (alive for more than 5 years). There was no difference between the two groups with respect to FIGO substage, age, World Health Organization score, and first-line platinum therapy. Classic clinical pathologic parameters were examined together with p53, Bcl-2, Ki-67, PDGFRalpha, P-glycoprotein, BRCA1, and DNA ploidy. Immunohistochemistry was used for scoring biomarker expression and image cytometry for DNA ploidy. All patients had primary debulking surgery followed by first-line platinum therapy. On multivariate analysis, the presence of ascites, debulking surgery and repeat laparotomy, clear-cell histology, elevated CA125, and high Ki-67 score were all found to be of prognostic importance. The long-term survivors were characterized by primary optimal cytoreduction surgery (<1 cm residual disease), attempt at maximal tumor debulking by experienced gynecological oncologic surgeons, and the absence of ascites. Normal CA125 level before platinum therapy and negative Ki-67 expression also predicted a more favorable prognosis. PMID:16343177

    Lymph node ratio (LNR) (positive lymph nodes/sampled lymph nodes) is predictive of survival in colon cancer. The aim of the present study was to validate the LNR as a prognostic factor and to determine the optimum LNR cutoff for distinguishing between “good prognosis” and “poor prognosis” colon cancer patients. From January 2003 to December 2007, patients with TNM stage III colon cancer operated on with at least of 3 years of follow-up and not lost to follow-up were included in this retrospective study. The two primary endpoints were 3-year overall survival (OS) and disease-free survival (DFS) as a function of the LNR groups and the cutoff. One hundred seventy-eight patients were included. There was no correlation between the LNR group and 3-year OS (P = 0.06) and a significant correlation between the LNR group and 3-year DFS (P = 0.03). The optimal LNR cutoff of 10% was significantly correlated with 3-year OS (P = 0.02) and DFS (P = 0.02). The LNR was not an accurate prognostic factor when fewer than 12 lymph nodes were sampled. Clarification and simplification of the LNR classification are prerequisites for use of this system in randomized control trials. An LNR of 10% appears to be the optimal cutoff. PMID:25058763

    Background. There is not yet an agreed adjuvant treatment for melanoma patients with American Joint Committee on Cancer stages III B and C. We report administration of an autologous melanoma vaccine to prevent disease recurrence. Patients and Methods. 126 patients received eight doses of irradiated autologous melanoma cells conjugated to dinitrophenyl and mixed with BCG. Delayed type hypersensitivity (DTH) response to unmodified melanoma cells was determined on the vaccine days 5 and 8. Gene expression analysis was performed on 35 tumors from patients with good or poor survival. Results. Median overall survival was 88 months with a 5-year survival of 54%. Patients attaining a strong DTH response had a significantly better (p = 0.0001) 5-year overall survival of 75% compared with 44% in patients without a strong response. Gene expression array linked a 50-gene signature to prognosis, including a cluster of four cancer testis antigens: CTAG2 (NY-ESO-2), MAGEA1, SSX1, and SSX4. Thirty-five patients, who received an autologous vaccine, followed by ipilimumab for progressive disease, had a significantly improved 3-year survival of 46% compared with 19% in nonvaccinated patients treated with ipilimumab alone (p = 0.007). Conclusion. Improved survival in patients attaining a strong DTH and increased response rate with subsequent ipilimumab suggests that the autologous vaccine confers protective immunity.

    Recently, the National Surgical Adjuvant Study of Colorectal Cancer in Japan, a randomised controlled trial of oral uracil–tegafur (UFT) adjuvant therapy for stage III rectal cancer, showed remarkable survival gains, compared with surgery alone. To evaluate value for money of adjuvant UFT therapy, cost-effective analysis was carried out. Cost-effectiveness analysis of adjuvant UFT therapy was carried out from a payer's perspective, compared with surgery alone. Overall survival and relapse-free survival were estimated by Kaplan–Meier method, up to 5.6 years from randomisation. Costs were estimated from trial data during observation. Quality-adjusted life-years (QALYs) were calculated using utility score from literature. Beyond observation period, they were simulated by the Boag model combined with the competing risk model. For 5.6-year observation, 10-year follow-up and over lifetime, adjuvant UFT therapy gained 0.50, 0.96 and 2.28 QALYs, and reduced costs by $2457, $1771 and $1843 per person compared with surgery alone, respectively (3% discount rate for both effect and costs). Cost-effectiveness acceptability and net monetary benefit analyses showed the robustness of these results. Economic evaluation of adjuvant UFT therapy showed that this therapy is cost saving and can be considered as a cost-effective treatment universally accepted for wide use in Japan. PMID:18797469

    The purpose of this study was to determine the toxicity profile of dendritic cell (DC) vaccination in stage III and IV melanoma patients, and to evaluate whether there is a correlation between side effects and immunologic and clinical outcome. This is a retrospective analysis of 82 stage III and 137 stage IV melanoma patients, vaccinated with monocyte-derived or naturally circulating autologous DCs loaded with tumor-associated antigens gp100 and tyrosinase. Median follow-up time was 54.3 months in stage III patients and 12.9 months in stage IV patients. Treatment-related adverse events occurred in 84% of patients; grade 3 toxicity was present in 3% of patients. Most common adverse events were flu-like symptoms (67%) and injection site reactions (50%), and both correlated with the presence of tetramer-positive CD8+ T cells (both P<0.001). In stage III melanoma patients experiencing flu-like symptoms, median overall survival (OS) was not reached versus 32.3 months in patients without flu-like symptoms (P=0.009); median OS in patients with an injection site reaction was not reached versus 53.7 months in patients without an injection site reaction (P<0.05). In stage IV melanoma patients (primary uveal and mucosal melanomas excluded), median OS in patients with or without flu-like symptoms was 13.1 versus 8.9 months, respectively (P=0.03); median OS in patients with an injection site reaction was 15.7 months versus 9.8 months in patients without an injection site reaction (P=0.003). In conclusion, DC vaccination is safe and tolerable and the occurrence of the immune-related side effects, such as flu-like symptoms and injection site reactions, correlates with immunologic and clinical outcome.

    Survivin is a microtubule-associated protein believed to be involved in preserving cell viability and regulating tumor cell mitosis, and it is overexpressed in many primary tumor types, including melanoma. YM155 is a first-in-class survivin suppressant. The purpose of this Phase 2 study was to evaluate the 6-month progression-free survival (PFS) rate in patients with unresectable Stage III or IV melanoma receiving a combination of YM155 plus docetaxel. The study had two parts: Part 1 established the dose of docetaxel that was tolerable in combination with YM155, and Part 2 evaluated the tolerable docetaxel dose (75 mg/m(2) ) in combination with YM155 (5 mg/m(2) per day continuous infusion over 168 h every 3 weeks). The primary endpoint was 6-month PFS rate. Secondary endpoints were objective response rate (ORR), 1-year overall survival (OS) rate, time from first response to progression, clinical benefit rate (CBR), and safety. Sixty-four patients with metastatic melanoma were treated with docetaxel and YM155. Eight patients received an initial docetaxel dose of 100 mg/m(2) and 56 patients received 75 mg/m(2) of docetaxel. Six-month PFS rate per Independent Review Committee (IRC) was 34.8% (n = 64; 95% CI, 21.3-48.6%), and per Investigator was 31.3% (n = 64; 95% CI, 19.5-43.9%). The best ORR (complete response [CR] + partial response [PR]) per IRC was 12.5% (8/64). The stable disease (SD) rate was 51.6% (33/64), leading to a CBR (CR + PR + SD) of 64.1% (41/64). Estimated probability of 1-year survival was 56.3%. YM155 is a novel agent showing modest activity when combined with docetaxel for treating patients with melanoma. YM155 was generally well tolerated, but the predetermined primary efficacy endpoint (i.e., 6-month PFS rate ≥20%) was not achieved. PMID:25533314

    Purpose: To investigate the potential effect of using {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in the initial assessment of patients with clinical Stage II or III breast cancer. Methods and Materials: During 14 consecutive months, 39 patients (40 tumors) who presented with Stage II or III breast cancer on the basis of a routine extension assessment were prospectively included in this study. PET/CT was performed in addition to the initial assessment. Results: In 3 cases, PET/CT showed extra-axillary lymph node involvement that had not been demonstrated with conventional techniques. Two of these patients had hypermetabolic lymph nodes in the subpectoral and infraclavicular regions, and the third had a hypermetabolic internal mammary node. PET/CT showed distant uptake in 4 women. Of these 4 women, 1 had pleural involvement and 3 had bone metastasis. Overall, of the 39 women, the PET/CT results modified the initial stage in 7 (18%). The modified staging altered the treatment plan for 5 patients (13%). It led to radiotherapy in 4 patients (bone metastasis, pleural lesion, subpectoral lymph nodes, and internal mammary nodes) and excision of, and radiotherapy to, the infraclavicular lymph nodes in 1 patient. Conclusions: PET/CT can provide information on extra-axillary lymph node involvement and can uncover occult distant metastases in a significant percentage of patients. Therefore, initial PET/CT could enable better treatment planning for patients with Stage II and III breast cancer.

    Background While adjuvant chemotherapy is preferable for high-risk colon cancer, treatment duration is controversial. Oral uracil and tegafur (UFT)/leucovorin (LV) is widely used as a standard adjuvant chemotherapy for colon cancer in Japan. We conducted a phase III trial to investigate the optimal duration of adjuvant chemotherapy for stage IIB/III colon cancer. Patients and methods Patients with curatively resected stage IIB/III colon cancer were eligible for enrollment in this trial. Patients were registered within 6 weeks after surgery and were randomly assigned to receive UFT/LV for 28 of 35 days for 6 months in the control group or for 5 consecutive days per week for 18 months in the study group. The primary end point was the disease-free survival (DFS), and the secondary end points were overall survival (OS) and safety. Result A total of 1071 patients were registered from 233 centers. A statistically significant difference in DFS was not observed between the study group and the control group; the 5-year DFS was 69% in the study group and 69% in the control group. The 5-year OS was 85% in the study group and 85% in the control group. Conclusion Eighteen-month treatment with UFT/LV did not improve DFS or OS compared with 6-month UFT/LV treatment in patients with stage IIB/III colon cancer. The important finding from this study is that not 18 months but 6 months of treatment is enough for postoperative UFT/LV for stage IIB/III colon cancer. Clinical trial number UMIN-CTR C000000245.

    Zinc-finger protein X-linked (ZFX) was recently identified as a novel oncoprotein in several human malignancies. In this study, we examined the correlation between ZFX expression and the clinical characteristics of stage II/III CRC patients, as well as the molecular mechanism by which ZFX apparently contributes to CRC tumor progression. Using immunohistochemistry, we detected expression of ZFX in CRC tissues collected from stage II/III patients and determined that its expression correlated with tumor differentiation and stage. Survival analysis indicated that patients with high ZFX expression had poorer overall and disease-free survival. ZFX knockdown in SW620 and SW480 CRC cells significantly inhibited cell proliferation and colony formation, enhanced apoptosis and induced cell cycle arrest. It also enhanced the sensitivity of CRC cells to 5-Fu. In a xenograft model, ZFX knockdown suppressed in vivo CRC tumor growth. Microarray analysis revealed the primary target of ZFX to be DUSP5. Whereas ZFX knockdown increased DUSP5 expression, DUSP5 knockdown rescued ZFX-mediated cell proliferation in ZFX knockdown cells. These findings demonstrate that ZFX promotes CRC progression by suppressing DUSP5 expression and suggest that ZFX is a novel prognostic biomarker and potentially useful therapeutic target in stage II/III CRC patients.

    Purpose: Although patients with stage III non-small cell lung cancer (NSCLC) are homogeneous according to the TNM staging system, they form a heterogeneous group, which is reflected in the survival outcome. The increasing amount of information for an individual patient and the growing number of treatment options facilitate personalized treatment, but they also complicate treatment decision making. Decision support systems (DSS), which provide individualized prognostic information, can overcome this but are currently lacking. A DSS for stage III NSCLC requires the development and integration of multiple models. The current study takes the first step in this process by developing and validating a model that can provide physicians with a survival probability for an individual NSCLC patient. Methods and Materials: Data from 548 patients with stage III NSCLC were available to enable the development of a prediction model, using stratified Cox regression. Variables were selected by using a bootstrap procedure. Performance of the model was expressed as the c statistic, assessed internally and on 2 external data sets (n=174 and n=130). Results: The final multivariate model, stratified for treatment, consisted of age, gender, World Health Organization performance status, overall treatment time, equivalent radiation dose, number of positive lymph node stations, and gross tumor volume. The bootstrapped c statistic was 0.62. The model could identify risk groups in external data sets. Nomograms were constructed to predict an individual patient's survival probability ( (www.predictcancer.org)). The data set can be downloaded at (https://www.cancerdata.org/10.1016/j.ijrobp.2015.02.048). Conclusions: The prediction model for overall survival of patients with stage III NSCLC highlights the importance of combining patient, clinical, and treatment variables. Nomograms were developed and validated. This tool could be used as a first building block for a decision support system.

    Purpose: The role of consolidative radiation therapy (RT) for stage III and IV diffuse large B-cell lymphoma (DLBCL) in the era of rituximab is not well defined. There is evidence that some patients with bulky disease may benefit, but patient selection criteria are not well established. We sought to identify a subset of patients who experienced a high local failure rate after receiving rituximab-based chemotherapy alone and hence may benefit from the addition of consolidative RT. Methods and Materials: Two hundred eleven patients with stage III and IV DLBCL treated between August 1999 and January 2012 were reviewed. Of these, 89 had a complete response to systemic therapy including rituximab and received no initial RT. Kaplan-Meier analysis and Cox proportional hazards regression were performed, with local recurrence (LR) as the primary outcome. Results: The median follow-up time was 43.9 months. Fifty percent of patients experienced LR at 5 years. In multivariate analysis, tumor ≥5 cm and stage III disease were associated with increased risk of LR. The 5-year LR-free survival was 47.4% for patients with ≥5-cm lesions versus 74.7% for patients with <5-cm lesions (P=.01). In patients with <5-cm tumors, the maximum standardized uptake value (SUVmax) was ≥15 in all patients with LR. The 5-year LR-free survival was 100% in SUV<15 versus 68.8% in SUV≥15 (P=.10). Conclusions: Advanced-stage DLBCL patients with stage III disease or with disease ≥5 cm appear to be at an increased risk for LR. Patients with <5-cm disease and SUVmax ≥15 may be at higher risk for LR. These patients may benefit from consolidative RT after chemoimmunotherapy.

    Background Postoperative radiotherapy (PORT) for thymic tumor is still controversial. The object of the study is to evaluate the role of PORT for stage I to III thymic tumors. Methods The Chinese Alliance for Research in Thymomas (ChART) was searched for patients with stage I to III thymic tumors who underwent surgical resection without neoajuvant therapy between 1994 and 2012. Univariate and multivariate survival analyses were performed. Cox proportional hazard model was used to determine the hazard ratio for death. Result From the ChART database, 1,546 stage I to III patients were identified. Among these patients, 649 (41.98%) received PORT. PORT was associated with gender, histological type (World Health Organization, WHO), thymectomy extent, resection status, Masaoka-Koga stage and adjuvant chemotherapy. The 5-year and 10-year overall survival (OS) rates and disease-free survival (DFS) rates for patients underwent surgery followed by PORT were 90% and 80%, 81% and 63%, comparing with 96% and 95%, 92% and 90% for patients underwent surgery alone (P=0.001, P<0.001) respectively. In univariate analysis, age, histological type (WHO), Masaoka-Koga stage, completeness of resection, and PORT were associated with OS. Multivariable analysis showed that histological type (WHO) (P=0.001), Masaoka-Koga stage (P=0.029) and completeness of resection (P=0.003) were independently prognostic factors of OS. In univariate analysis, gender, myasthenia gravis, histological subtype, Masaoka-Koga stage, surgical approach, PORT and completeness of resection were associated with DFS. Multivariate analysis showed that histological subtype (P<0.001), Masaoka-Koga stage (P=0.005) and completeness of resection (P=0.006) were independent prognostic factors for DFS. Subgroup analysis showed that patients with incomplete resection underwent PORT achieved better OS and DFS (P=0.010, 0.017, respectively). However, patients with complete resection underwent PORT had the worse OS and DFS (P<0

    Ferritin stores iron within a hollow protein shell as a polynuclear Fe(III) hydrous oxide core. Although iron uptake into ferritin has been studied previously, the early stages in the creation of the core need to be clarified. These are dealt with in this paper by using Moessbauer spectroscopy, a technique that enables several types of Fe(II) and Fe(III) to be distinguished. Systematic Moessbauer studies were performed on samples prepared by adding {sup 57}Fe(II) atoms to apoferritin as a function of pH (5.6-7.0), n (the number of Fe/molecule (4-480)), and t{sub f} (the time the samples were held at room temperature before freezing). Four different Fe(III) species were identified: solitary Fe(III) atoms giving relaxation spectra, which can be identified with the species observed before by EPR and UV difference spectroscopy; oxo-bridged dimers giving doublet spectra with large splitting, observed for the first time in ferritin; small Fe(III) clusters giving doublets of smaller splitting and larger antiferromagnetically coupled Fe(III) clusters, similar to those found previously in larger ferritin iron cores, which, for samples with n {ge} 40, gave magnetically split spectra at 4.1 K. Both solitary Fe(III) and dimers diminished with time, suggesting that they are intermediates in the formation of the iron core. Two kinds of divalent iron were distinguished for n = 480, which may correspond to bound and free Fe(II).

    Purpose: In this Phase II study, we evaluated the efficacy and toxicity of chemoradiotherapy (CRT) with cisplatin (CDDP) and 5-fluorouracil (5-FU) for Stage II-III esophageal squamous cell carcinoma (ESCC). Patients and Methods: Patients with clinical Stage II-III (T1N1M0 or T2-3N0-1M0) thoracic ESCC were enrolled between April 2000 and March 2002. Chemotherapy comprised two courses of protracted infusion of 5-FU (400 mg/m{sup 2}/day) on Days 1-5 and 8-12, and 2-h infusion of CDDP (40 mg/m{sup 2}) on Days 1 and 8; this regimen was repeated every 5 weeks. Concurrent radiotherapy involved 60-Gy irradiation (30 fractions) for 8 weeks with a 2-week break. Responders received two courses of 5-FU (800 mg/m{sup 2}/day) on Days 1-5 and CDDP (80 mg/m{sup 2}) on Day 1. Final analysis was conducted in March 2007. Survival and late toxicities were monitored for 5 years. Results: The characteristics of the 76 patients enrolled were as follows: median age, 61 years; male/female, 68/8; performance status 0/1, 59/17 patients; Stage IIA/IIB/III, 26/12/38 patients. Of the 74 eligible patients, 46 (62.2%) achieved complete response. Median survival time was 29 months, with 3- and 5-year survival rates of 44.7% and 36.8%, respectively. Acute toxicities included Grade 3/4 esophagitis (17%), nausea (17%), hyponatremia (16%), and infection without neutropenia (12%). Late toxicities comprised Grade 3/4 esophagitis (13%), pericardial (16%) and pleural (9%) effusion, and radiation pneumonitis (4%), causing 4 deaths. Conclusions: CRT is effective for Stage II-III ESCC with manageable acute toxicities and can provide a nonsurgical treatment option. However, further improvement is required for reduction in late toxicity.

    Postsurgical chemotherapy is guideline-recommended therapy for stage III colon cancer patients. Factors associated with patients not receiving adjuvant chemotherapy were identified in numerous studies; comorbidity was recognized as an important factor besides patient's age. We assessed the association between comorbidity and the use of adjuvant chemotherapy and type of chemotherapy regimen. Stage III colon cancer patients who underwent surgical resection were obtained from ten Centers for Disease Control and Prevention (CDC)-NPCR Specialized Registries which participated in the Comparative Effectiveness Research (CER) project. Comorbidity was classified into no comorbidity recorded, Charlson, non-Charlson comorbidities, number, and severity of Charlson comorbidity. Pearson chi-square test and multivariable logistic regression were employed. Of 3180 resected stage III colon cancer patients, 64% received adjuvant chemotherapy. After adjusting for patient's demographic and tumor characteristics, there were no significant differences in receipt of chemotherapy between Charlson and non-Charlson comorbidity. However, patients who had two or more Charlson comorbidities or had moderate to severe disease were significantly less likely to have chemotherapy (ORs 0.69 [95% CI, 0.51-0.92] and 0.62 [95% CI, 0.42-0.91], respectively) when compared with those with non-Charlson comorbidity. In addition, those with moderate or severe comorbidities were more likely to receive single chemotherapy agent (P < 0.0001). Capecitabine and FOLFOX were the most common single- and multi-agent regimens regardless of type of comorbidity grouping. Both the number and severity of comorbidity were significantly associated with receipt of guideline-recommended chemotherapy and type of agent in stage III resected colon cancer patients. Better personalized care based on individual patient's condition ought to be recognized. PMID:26773804

    Purpose: Local and distant failure rates remain high despite aggressive chemoradiation (CRT) treatment for Stage III non-small-cell lung cancer. We conducted preclinical studies of docetaxel's cytotoxic and radiosensitizing effects on lung cancer cell lines and designed a pilot study to target distant micrometastasis upfront with one-cycle induction chemotherapy, followed by low-dose radiosensitizing docetaxel CRT. Methods and Materials: A preclinical study was conducted in human lung cancer cell lines NCI 520 and A549. Cells were treated with two concentrations of docetaxel for 3 h and then irradiated immediately or after a 24-h delay. A clonogenic survival assay was conducted and analyzed for cytotoxic effects vs. radiosensitizing effects of docetaxel. A pilot clinical study was designed based on preclinical study findings. Twenty-two patients were enrolled with a median follow-up of 4 years. Induction chemotherapy consisted of 75 mg/m{sup 2} of docetaxel and 75 mg/m{sup 2} of cisplatin on Day 1 and 150 mg/m{sup 2} of recombinant human granulocyte colony-stimulating factor on Days 2 through 10. Concurrent CRT was started 3 to 6 weeks later with twice-weekly docetaxel at 10 to 12 mg/m{sup 2} and daily delayed radiation in 1.8-Gy fractions to 64.5 Gy for gross disease. Results: The preclinical study showed potent cytotoxic effects of docetaxel and subadditive radiosensitizing effects. Delaying radiation resulted in more cancer cell death. The pilot clinical study resulted in a median survival of 32.6 months for the entire cohort, with 3- and 5-year survival rates of 50% and 19%, respectively, and a distant metastasis-free survival rate of 61% for both 3 and 5 years. A pattern-of-failure analysis showed 75% chest failures and 36% all-distant failures. Therapy was well tolerated with Grade 3 esophagitis observed in 23% of patients. Conclusions: One-cycle full-dose docetaxel/cisplatin induction chemotherapy with recombinant human granulocyte colony-stimulating factor

    Background: Interclinician variability in defining target volumes is a problem in conformal radiotherapy. A CD-ROM-based contouring tool was used to conduct a dummy run in an international trial of involved-field chemoradiotherapy for Stage III non-small-cell lung cancer. Methods and Materials: The CT scan of an eligible patient was installed on an 'auto-run' CD-ROM incorporating a contouring program based on ImageJ for Windows, which runs on any personal computer equipped with a CD-ROM drive. This tool was initially piloted at four academic centers and was subsequently mailed, together with all relevant clinical, radiologic, and positron emission tomography findings, to all participating centers in the international trial. Clinicians were instructed to contour separate gross tumor volumes (GTVs) for the tumor and two enlarged nodes and a clinical target volume for the hilus. A reference 'consensus' target volume for each target was jointly generated by three other clinicians. Results: The data received from the four academic centers and 16 study participants were suitable for analysis. Data from one center was unsuitable for detailed analysis because the target volumes were contoured at 1.2-cm intervals. GTVs were available for a total of 21 tumors and 19 nodes, and 15 hilar clinical target volumes were available. The mean GTV of the primary tumor was 13.6 cm{sup 3} (SD, 5.2; median, 12.3; range, 8.3-26.9). The variation in the center of the mass relative to the mean center of the mass in the left-right, ventrodorsal, and craniocaudal axes was 1.5, 0.4, and 1.0 mm, respectively. The largest volume variation was observed for the right hilar clinical target volume (mean, 33.7 cm{sup 3}; SD, 31.2; median, 20.3; range, 4.8-109.9). Smaller variations were observed for the subcarinal node (mean, GTV, 1.9 cm{sup 3}; SD, 1.2; median, 1.7; range, 0.5-5.3), except caudally where the node was difficult to distinguish from the pericardium.

    In stage III non-small cell lung cancer (NSCLC), the standard of care in young patients is chemoradiotherapy, but this standard is not as clearly established for older patients. We aimed to determine the efficacy and harm associated with chemoradiotherapy versus radiotherapy alone in elderly (≥70 years), stage III NSCLC patients through a systematic review. We conducted a systematic search of MEDLINE, EMBASE, CENTRAL, Scopus, Web of Science and conference proceedings. Two reviewers independently identified randomized trials (RCT) and extracted trial-level data. Risk of bias was assessed and meta-analysis was conducted looking at survival and safety outcomes. We included three trials and subgroup data from one systematic review. The three RCTs had high risk of bias due primarily to lack of blinding and the systematic review scored 4/11 using the AMSTAR tool. Overall survival (HR 0.66, 95% CI 0.53-0.82; I2 0%; 3 trials; 407 patients) and progression-free survival (HR 0.67, 95% CI 0.53-0.85; I2 0%; 2 trials; 327 patients) both favored chemoradiotherapy. Risk of treatment-related death and grade 3+ pneumonitis were not significantly different between groups. In conclusion, treatment of stage III NSCLC patients 70 years or older with chemotherapy and radiotherapy is associated with improved overall survival compared to radiotherapy alone. With the exception of increased hematological toxicity, CRT appears to be tolerable in fit elderly patients and represents a reasonable standard of clinical care. PMID:27565937

    Purpose: To compare chemotherapy alone with chemoradiation therapy in stage III-IV(M0) gastric cancer treated with R0 gastrectomy and D2 lymph node dissection. Methods and Materials: The chemotherapy arm received 5 cycles of fluorouracil and leucovorin (FL), and the chemoradiation therapy arm received 1 cycle of FL, then radiation therapy of 45 Gy concurrently with 2 cycles of FL, followed by 2 cycles of FL. Intent-to-treat analysis and per-protocol analyses were performed. Results: Between May 6, 2002 and June 29, 2006, a total of 90 patients were enrolled. Forty-four were randomly assigned to the chemotherapy arm and 46 to the chemoradiation therapy arm. Treatment was completed as planned by 93.2% of patients in the chemotherapy arm and 87.0% in the chemoradiation therapy arm. Overall intent-to-treat analysis showed that addition of radiation therapy to chemotherapy significantly improved locoregional recurrence-free survival (LRRFS) but not disease-free survival. In subgroup analysis for stage III, chemoradiation therapy significantly prolonged the 5-year LRRFS and disease-free survival rates compared with chemotherapy (93.2% vs 66.8%, P=.014; 73.5% vs 54.6%, P=.056, respectively). Conclusions: Addition of radiation therapy to chemotherapy could improve the LRRFS in stage III gastric cancer treated with R0 gastrectomy and D2 lymph node dissection.

    2013-01-01

    Background Breast cancer incidence is increasing. The survival rate varies and is longer in high-income countries. In Brazil, lower-income populations rely on the Unified Public Health System (Sistema Único de Saude, SUS) for breast cancer care. The goal of our study is to evaluate the survival of patients with operable breast cancer stages I-III at a Brazilian public hospital that treats mostly patients from the SUS. Methods A cohort study of patients who underwent surgery for breast cancer treatment at the Clinical Hospital of the Federal University of Minas Gerais from 2001 to 2008 was performed, with a population of 897 cases. Information on tumor pathology and staging, as well as patients’ age and type of health coverage (SUS or private system) was collected. A probabilistic record linkage was performed with the database of the Mortality Information System to identify patients who died by December 31th, 2011. The basic cause of death was retrieved, and breast cancer-specific survival rates were estimated with the Kaplan-Meier method. The Cox proportional hazards model was used for univariate and multivariate analysis of factors related to survival. Results A total of 282 deaths occurred during the study’s period, 228 of them due to breast cancer. Five-year breast cancer-specific survival rates were 95.5% for stage I, 85.1% for stage II and 62.1% for stage III disease. Patients from the SUS had higher stages at diagnosis (42% was in stage III, and from the private system only 17.6% was in this stage), and in the univariate but not multivariate analysis, being treated by the SUS was associated with shorter survival (hazard ratio, HR = 2.22, 95% CI 1.24-3.98). In the multivariate analysis, larger tumor size, higher histologic grade, higher number of positive nodes and age older than 70 years were associated with a shorter breast cancer-specific survival. Conclusions Five-year breast cancer survival was comparable to other Brazilian cohorts. Patients

    Purpose: Total-abdominal hysterectomy and bilateral salpingo-oophorectomy (TAHBSO) is the gold-standard therapy for patients with endometrial carcinoma. However, patients with high operative risks are usually treated with radiation therapy (RT) alone. The goal of this study was to update our experience of high-dose-rate brachytherapy (HDRB), with or without external-beam irradiation (EBRT), for such patients. Methods and Materials: Between 1984 and 2003, 38 patients with Stage I and Stage II adenocarcinoma of the endometrium considered high operative risk received RT as the primary treatment. The median age was 74.1 years. Before 1996, the local extent of the disease was assessed by an examination under anesthesia (EUA) and by EUA and magnetic resonance imaging (MRI) thereafter. Eight patients (21%) were treated with combined HDRB and EBRT, and 30 patients (79%) were treated with with HDRB alone. The median HDRB dose was 23.9 Gy, typically delivered in 3 fractions in a weekly schedule. The median EBRT dose was 42 Gy. Results: At a median follow-up of 57.5 months for patients at risk, 11 patients (29%) have failed: 6 patients (16%) locally, 4 patients (10.5%) distantly, and 1 patient (3%) locally and distantly. Local failure was established by biopsy, and 4 patients were salvaged by TAHBSO. Higher stage and higher grade were both associated with increased failure rate. The 15-year disease-specific survival (DSS) was 78% for all stages, 90% for Stage I, and 42% for Stage II (p < 0.0001). The 15-year DSS was 91% for Grade I and 67% for Grade II and III combined (p = 0.0254). Patients with Stage I disease established by MRI (11 patients) and who received a total HDRB dose of 30 Gy had a DSS rate of 100% at 10 years. Four patients experienced late toxicities: 1 Grade II and 3 Grade III or IV. Conclusion: Medically inoperable Stage I endometrial carcinoma may be safely and effectively treated with HDRB as the primary therapy. In selected Stage I patients, our results are

    Purpose: While consolidation radiation therapy (i.e., RT administered after chemotherapy) is routine treatment for patients with early-stage diffuse large B-cell lymphoma (DLBCL), the role of consolidation RT in stage III-IV DLBCL is controversial. Methods and Materials: Cases of patients with stage III-IV DLBCL treated from 1991 to 2009 at Duke University, who achieved a complete response to chemotherapy were reviewed. Clinical outcomes were calculated using the Kaplan-Meier method and were compared between patients who did and did not receive RT, using the log-rank test. A multivariate analysis was performed using Cox proportional hazards model. Results: Seventy-nine patients were identified. Chemotherapy (median, 6 cycles) consisted of anti-CD20 antibody rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; 65%); cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP; 22%); or other (13%). Post-chemotherapy imaging consisted of positron emission tomography (PET)/computed tomography (CT) (73%); gallium with CT (14%); or CT only (13%). Consolidation RT (median, 25 Gy) was given to involved sites of disease in 38 (48%) patients. Receipt of consolidation RT was associated with improved in-field control (92% vs. 69%, respectively, p = 0.028) and event-free survival (85% vs. 65%, respectively, p = 0.014) but no difference in overall survival (85% vs. 78%, respectively, p = 0.15) when compared to patients who did not receive consolidation RT. On multivariate analysis, no RT was predictive of increased risk of in-field failure (hazard ratio [HR], 8.01, p = 0.014) and worse event-free survival (HR, 4.3, p = 0.014). Conclusions: Patients with stage III-IV DLBCL who achieve negative post-chemotherapy imaging have improved in-field control and event-free survival with low-dose consolidation RT.

    Surgical resection offers the best chance for cure for early stage non-small-cell lung cancer (NSCLC, stage I, II, IIIA), but the 5-year survival rates are only moderate, with systemic relapse being the major cause of death. Pre-operative (neo-adjuvant) chemotherapy has shown promise in small trials restricted to stage IIIA patients. We believe similar trials are now appropriate in all stages of operable lung cancer. A feasibility study was performed in 22 patients with early stage (IB, II, IIIA) resectable NSCLC; randomized to either three cycles of chemotherapy [mitomycin-C 8 mg m−2, vinblastine 6 mg m−2 and cisplatin 50 mg m−2 (MVP)] followed by surgery (n = 11), or to surgery alone. Of 40 eligible patients, 22 agreed to participate (feasibility 55%) and all complied with the full treatment schedule. All symptomatic patients achieved either complete (50%) or partial (50%) relief of tumour-related symptoms with pre-operative chemotherapy. Fifty-five per cent achieved objective tumour response, and a further 27% minor tumour shrinkage; none had progressive disease. Partial pathological response was seen in 50%. No severe (WHO grade III–IV) toxicities occurred. No significant deterioration in quality of life was detected during chemotherapy. Pre-operative MVP chemotherapy is feasible in early stage NSCLC, and this study has now been initiated as a UK-wide Medical Research Council phase III trial. © 1999 Cancer Research Campaign PMID:10188899

    2010-01-01

    Background Plant class III peroxidases exist as a large multigenic family involved in numerous functions suggesting a functional specialization of each gene. However, few genes have been linked with a specific function. Consequently total peroxidase activity is still used in numerous studies although its relevance is questionable. Transcriptome analysis seems to be a promising tool to overcome the difficulties associated with the study of this family. Nevertheless available microarrays are not completely reliable for this purpose. We therefore used a macroarray dedicated to the 73 class III peroxidase genes of A. thaliana to identify genes potentially involved in flower and fruit development. Results The observed increase of total peroxidase activity during development was actually correlated with the induction of only a few class III peroxidase genes which supports the existence of a functional specialization of these proteins. We identified peroxidase genes that are predominantly expressed in one development stage and are probable components of the complex gene networks involved in the reproductive phase. An attempt has been made to gain insight into plausible functions of these genes by collecting and analyzing the expression data of different studies in plants. Peroxidase activity was additionally observed in situ in the silique dehiscence zone known to be involved in pod shattering. Because treatment with a peroxidase inhibitor delayed pod shattering, we subsequently studied mutants of transcription factors (TF) controlling this mechanism. Three peroxidases genes -AtPrx13, AtPrx30 and AtPrx55- were altered by the TFs involved in pod shatter. Conclusions Our data illustrated the problems caused by linking only an increase in total peroxidase activity to any specific development stage or function. The activity or involvement of specific class III peroxidase genes needs to be assessed. Several genes identified in our study had not been linked to any particular

    p21-Activated kinase 6 (PAK6) has been implicated in radiotherapy and docetaxel resistance. We have further evaluated PAK6 as a predictor of 5-fluorouracil (5-FU) treatment response in colon cancer. Here we report that in colon cancer PAK6 promotes tumor progression and chemoresistance both in vitro and in vivo. In the clinical analysis, PAK6 was overexpressed in 104 of 147 (70.75%) stage II and III patients who received 5-FU based chemotherapy after surgery. Multivariate Cox regression analysis indicated that PAK6 was an independent prognostic factor for overall survival (P < 0.001) and disease-free survival (P < 0.001). Colon cancer cell lines showed increased PAK6 expression upon 5-FU treatment. In PAK6-knockdown cells treated with 5-FU, cell viability and phosphorylation of BAD decreased, and the number of apoptotic cells, levels of cleaved caspase 3 and PARP increased compared to control cells. The opposite was observed in PAK6 overexpressing cells. Short hairpin RNA knockdown of PAK6 blocked cells in G2-M phase. Furthermore, Animal experiments results in vivo are consistent with outcomes in vitro. This study demonstrates that PAK6 is an independent prognostic factor for adjuvant 5-FU-based chemotherapy in patients with stage II and stage III colon cancer. PMID:25426562

    The early stages of myoepithelial proliferation in 14 mixed canine mammary tumours were studied by light- and electron microscopy. Two different early stages can be distinguished: 1. Proliferations inside the basal lamina with partial maintenance of the organoid pattern. 2. Proliferations with a break through the basal lamina and transposition of tumour cells into the surrounding connective tissue. The intracytoplasmic fibrillae of myoepithelial tumour cells are striped periodically and thicker than those of normal myothelia. It is suggested that the amorphous as well as the fibrous intercellular substance in the early stages is derived from the described myoepithelial tumour cells. PMID:169622

  6. Resolving Early Stages of Homogeneous Iron(III) Oxyhydroxide Formation from Iron(III) Nitrate Solutions at pH 3 Using Time-Resolved SAXS

    PubMed Central

    2015-01-01

    Small angle X-ray scattering (SAXS) measurements coupled to a stopped-flow device has permitted the observation of the kinetics of Fe(III) oxyhydroxide (FeOx) formation and transformation from around 1 s to 30 min after initiation under environmentally relevant conditions at pH 3. The Unified Model approach was used to determine the evolution of multiple key parameters (particle scattering mass, mean particle volume, particle concentration, particle dimensionality, and particle size) for two separate structural levels as a function of time, with the results obtained enabling clarification of the mechanisms underlying FeOx formation and transformation under these conditions. Colloidal primary particles (radius of gyration 2–10 nm) that were observable by SAXS formed within 1 s of stopping the flow and subsequently grew over several minutes, first by cluster–cluster addition and then by a monomer-addition mechanism. Aggregation of these primary particles via a secondary cluster–cluster addition mechanism simultaneously resulted in a distinct population of larger (25–40 nm radius of gyration) secondary particles. The primary particles evolved into compact spheroidal forms with fractally rough surfaces, while the secondary particles were relatively open mass fractal structures. Comparison of the observed rates of these processes with those predicted for Fe polymerization indicates that kinetics of primary particle formation were likely controlled initially by rates of exchange between water molecules coordinated with Fe and those in the bulk solution. These findings provide new insights into the mechanisms underlying FeOx formation and transformation, and the kinetics of these mechanisms, at pH 3. PMID:24601665

    The aim of the present study was to investigate markers in surgically resected specimens of colorectal cancer that can be used to predict the response to chemotherapy. The mRNA expression levels of enzymes involved in 5-fluorouracil (5-FU) metabolism and folate metabolism were measured in formalin-fixed, paraffin-embedded tumor sections obtained from the primary tumors of 54 patients with resected stage II or III colorectal cancer who received S-1 for one year. The 5-FU metabolizing enzymes studied were thymidylate synthase, dihydropyrimidine dehydrogenase and thymidine phosphorylase (TP). The folate metabolizing enzymes studied were folypolyglutamate synthetase, γ-glutamyl hydrolase and dihydrofolate reductase. The associations between the mRNA expression levels of these enzymes and clinical variables were investigated. Tumors were classified as exhibiting high or low expression as compared with the median mRNA expression level of each metabolizing enzyme defined as the cutoff value. The associations between the high and low expression levels of each enzyme and disease-free survival (DFS) were analyzed with the use of Kaplan-Meier curves and the log-rank test. DFS was not significantly associated with the relative mRNA expression level of any metabolizing enzyme in the study group as a whole, but there was a trend toward longer DFS in patients with high TP expression (P=0.066). In patients with stage III colorectal cancer, high TP expression was associated with significantly improved outcomes compared with low TP expression (P=0.039). These results indicate that the mRNA expression of TP, a metabolizing enzyme of 5-FU, is a significant predictor of response to post-operative chemotherapy with S-1 in patients with stage III colorectal cancer.

    Purpose: To investigate the feasibility of modeling Stage III lung cancer tumor and node positions from anatomical surrogates. Methods and Materials: To localize their centroids, the primary tumor and lymph nodes from 16 Stage III lung cancer patients were contoured in 10 equal-phase planning four-dimensional (4D) computed tomography (CT) image sets. The centroids of anatomical respiratory surrogates (carina, xyphoid, nipples, mid-sternum) in each image set were also localized. The correlations between target and surrogate positions were determined, and ordinary least-squares (OLS) and partial least-squares (PLS) regression models based on a subset of respiratory phases (three to eight randomly selected) were created to predict the target positions in the remaining images. The three-phase image sets that provided the best predictive information were used to create models based on either the carina alone or all surrogates. Results: The surrogate most correlated with target motion varied widely. Depending on the number of phases used to build the models, mean OLS and PLS errors were 1.0 to 1.4 mm and 0.8 to 1.0 mm, respectively. Models trained on the 0%, 40%, and 80% respiration phases had mean ({+-} standard deviation) PLS errors of 0.8 {+-} 0.5 mm and 1.1 {+-} 1.1 mm for models based on all surrogates and carina alone, respectively. For target coordinates with motion >5 mm, the mean three-phase PLS error based on all surrogates was 1.1 mm. Conclusions: Our results establish the feasibility of inferring primary tumor and nodal motion from anatomical surrogates in 4D CT scans of Stage III lung cancer. Using inferential modeling to decrease the processing time of 4D CT scans may facilitate incorporation of patient-specific treatment margins.

    Purpose: To evaluate the overall and cause-specific survival in patients with Stage III-IVb head and neck squamous cell carcinoma treated with radiotherapy (RT) as the primary local treatment modality. Methods and Materials: The survival of patients with American Joint Committee on Cancer Stage III-IVb head and neck squamous cell carcinoma treated with primary RT was queried using the Surveillance, Epidemiology and End Results database. The effect of the year of treatment on overall and cause-specific survival was analyzed as a categorical and continuous variable. The patterns of care for these patients were also evaluated. Results: Between 1988 and 2004, 6,759 patients were identified. Survival was significantly improved in patients treated more recently. When analyzed as a continuous variable, each year was associated with a 3% and 4.1% reduction in the relative risk of overall and cause-specific mortality, respectively (p < 0.0001). Patients treated after 1998 had a 7.6% and 6.1% absolute improvement in overall and cause-specific survival, respectively, compared with patients treated before 1998 (overall survival, hazard ratio, 0.81; cause-specific survival, hazard ratio, 0.77; p < 0.0001). This benefit in survival was limited to tumors of the oral cavity, oropharynx, and hypopharynx. The use of RT increased among patients treated more recently. This shift in patterns of care was most pronounced for tumors of the larynx and hypopharynx. Conclusions: The overall and cause-specific survival of patients with Stage III-IVb head and neck squamous cell carcinoma treated with primary RT has improved with time. The improvement is consistent with that observed in a large meta-analysis of randomized patients treated with concurrent chemoradiotherapy.

    Hypothesis We propose that single-nucleotide polymorphisms (SNPs) in genes of the VEGF-pathway of angiogenesis will associate with survival in non-small cell lung cancer (NSCLC) patients. Methods Fifty-three SNPs in VEGF-pathway genes were genotyped in 150 European stage I-III NSCLC patients and tested for associations with patient survival. Replication was performed in an independent cohort of 142 European stage I-III patients. Reporter gene assays were used to assess the effects of SNPs on transcriptional activity. Results In the initial cohort, five SNPs associated (q<0.05) with relapse-free survival (RFS). The minor alleles of intronic FLT1 SNPs, rs7996030 and rs9582036, associated with reduced RFS (HR=1.67 [95% CI, 1.22 to 2.29] and HR=1.51 [95% CI, 1.14 to 2.01], respectively) and reduced transcriptional activity. The minor alleles of intronic KRAS SNPs, rs12813551 and rs10505980, associated with increased RFS (HR=0.64 [0.46 to 0.87] and HR=0.64 [0.47 to 0.87], respectively) and the minor allelic variant of rs12813551 also reduced transcriptional activity. Lastly, the minor allele of the intronic KRAS SNP rs10842513 associated with reduced RFS (HR=1.65 [95% CI, 1.16 to 2.37]). Analysis of the functional variants suggests they are located in transcriptional enhancer elements. The negative effect of rs9582036 on RFS was confirmed in the replication cohort (HR=1.69 [0.99 to 2.89], p=0.028) and the association was significant in pooled analysis of both cohorts (HR=1.67 [1.21-2.30], p=0.0001). Conclusions The functional FLT1 variant rs9582036 is a prognostic determinant of recurrence in stage I-III NSCLC. Its predictive value should be tested in the adjuvant setting of stage I-III NSCLC.

    Purpose: Several surgical series have identified subcarinal, contralateral, and multilevel nodal involvement as predictors of poor overall survival in patients with Stage III non-small-cell lung cancer (NSCLC) treated with definitive resection. This retrospective study evaluates the impact of extent and location of mediastinal lymph node (LN) involvement on survival in patients with Stage III NSCLC treated with definitive radiotherapy. Methods and Materials: We analyzed 106 consecutive patients with T1-4 N2-3 Stage III NSCLC treated with definitive radiotherapy at University of Pennsylvania between January 2003 and February 2009. For this analysis, mediastinal LN stations were divided into four mutually exclusive groups: supraclavicular, ipsilateral mediastinum, contralateral mediastinum, and subcarinal. Patients' conditions were then analyzed according to the extent of involvement and location of mediastinal LN stations. Results: The majority (88%) of patients received sequential or concurrent chemotherapy. The median follow-up time for survivors was 32.6 months. By multivariable Cox modeling, chemotherapy use (hazard ratio [HR]: 0.21 [95% confidence interval (CI): 0.07-0.63]) was associated with improved overall survival. Increasing primary tumor [18F]-fluoro-2-deoxy-glucose avidity (HR: 1.11 [CI: 1.06-1.19]), and subcarinal involvement (HR: 2.29 [CI: 1.11-4.73]) were significant negative predictors of overall survival. On univariate analysis, contralateral nodal involvement (HR: 0.70 [CI: 0.33-1.47]), supraclavicular nodal involvement (HR: 0.78 [CI: 0.38-1.67]), multilevel nodal involvement (HR: 0.97 [CI: 0.58-1.61]), and tumor size (HR: 1.04 [CI: 0.94-1.14]) did not predict for overall survival. Patients with subcarinal involvement also had lower rates of 2-year nodal control (51.2% vs. 74.9%, p = 0.047) and 2-year distant control (28.4% vs. 61.2%, p = 0.043). Conclusions: These data suggest that the factors that determine oncologic outcome in Stage III NSCLC

    Purpose: To propose a lymph node (N) staging system for nasopharyngeal carcinoma (NPC) based on the International Consensus Guidelines for lymph node (LN) levels and MRI-determined nodal variables. Methods and Materials: The MRI scans and medical records of 749 NPC patients receiving intensity modulated radiation therapy with or without chemotherapy were retrospectively reviewed. The prognostic significance of nodal level, laterality, maximal axial diameter, extracapsular spread, necrosis, and Union for International Cancer Control/American Joint Committee on Cancer (UICC/AJCC) size criteria were analyzed. Results: Nodal level and laterality were the only independent prognostic factors for distant failure and disease failure in multivariate analysis. Compared with unilateral levels Ib, II, III, and/or Va involvement (hazard ratio [HR] 1), retropharyngeal lymph node involvement alone had a similar prognostic value (HR 0.71; 95% confidence interval [CI] 0.43-1.17; P=.17), whereas bilateral levels Ib, II, III, and/or Va involvement (HR 1.65; 95% CI 1.06-2.58; P=.03) and levels IV, Vb, and/or supraclavicular fossa involvement (HR 3.47; 95% CI 1.92-6.29; P<.01) both significantly increased the HR for distant failure. Thus we propose that the N category criteria could be revised as follows: N0, no regional LN metastasis; N1, retropharyngeal lymph node involvement, and/or unilateral levels Ib, II, III, and/or Va involvement; N2, bilateral levels Ib, II, III, and/or Va involvement; N3, levels IV, Vb, and/or supraclavicular fossa involvement. Compared with the 7th edition of the UICC/AJCC criteria, the proposed N staging system provides a more satisfactory distinction between the HRs for regional failure, distant failure, and disease failure in each N category. Conclusions: The proposed N staging system defined by the International Consensus Guidelines and laterality is predictive and practical. However, because of no measurements of the maximal nodal diameter on MRI slices

    Purpose: To investigate influence of various pretreatment prognostic factors in patients with early stage (I/II) non-small-cell lung cancer (NSCLC) treated with hyperfractionated radiation therapy alone. Patients and Methods: One hundred and sixteen patients were treated with tumor doses of 69.6 Gy, 1.2-Gy, twice-daily fractionation. There were 49 patients with Stage I and 67 patients with Stage II. Eighty patients had Karnofsky performance status (KPS) 90-100 and 95 patients had <5% weight loss. Peripheral tumors were observed in 57 patients. Squamous histology was observed in 70 patients and the majority of patients had concomitant disease (n = 72). Results: The median survival time for all patients was 29 months; 5-year survival was 29%. The median time to local progression and the distant metastasis were not achieved, whereas 5-year local progression-free and distant metastasis-free survivals were 50% and 72%, respectively. Multivariate analysis identified KPS, weight loss, location, histology, and the reason for not undergoing surgery as prognostic factors for survival. KPS, location, and histology influenced local progression-free survival, whereas only KPS and weight loss influenced distant metastasis-free survival. Conclusions: This retrospective analysis identified KPS and weight loss as the most important prognostic factors of outcome in patients with early-stage NSCLC treated with hyperfractionation radiation therapy.

    This paper explores the utility of cluster- and case-based surveillance established in government hospitals in Bangladesh to detect Nipah virus, a stage III zoonotic pathogen. Physicians listed meningo-encephalitis cases in the 10 surveillance hospitals and identified a cluster when ⩾2 cases who lived within 30 min walking distance of one another developed symptoms within 3 weeks of each other. Physicians collected blood samples from the clustered cases. As part of case-based surveillance, blood was collected from all listed meningo-encephalitis cases in three hospitals during the Nipah season (January-March). An investigation team visited clustered cases' communities to collect epidemiological information and blood from the living cases. We tested serum using Nipah-specific IgM ELISA. Up to September 2011, in 5887 listed cases, we identified 62 clusters comprising 176 encephalitis cases. We collected blood from 127 of these cases. In 10 clusters, we identified a total of 62 Nipah cases: 18 laboratory-confirmed and 34 probable. We identified person-to-person transmission of Nipah virus in four clusters. From case-based surveillance, we identified 23 (4%) Nipah cases. Faced with thousands of encephalitis cases, integrated cluster surveillance allows targeted deployment of investigative resources to detect outbreaks by stage III zoonotic pathogens in resource-limited settings.

    Purpose: In non-small cell lung cancer, gross tumor volume (GTV) influences survival more than other risk factors. This could also apply to small cell lung cancer. Methods and Materials: Analysis of our prospective database with stage I to III SCLC patients referred for concurrent chemo radiation therapy. Standard treatment was 45 Gy in 1.5-Gy fractions twice daily concurrently with carboplatin-etoposide, followed by prophylactic cranial irradiation (PCI) in case of non-progression. Only fluorodeoxyglucose (FDG)-positron emission tomography (PET)-positive or pathologically proven nodal sites were included in the target volume. Total GTV consisted of post chemotherapy tumor volume and pre chemotherapy nodal volume. Survival was calculated from diagnosis (Kaplan-Meier ). Results: A total of 119 patients were included between May 2004 and June 2009. Median total GTV was 93 ± 152 cc (7.5-895 cc). Isolated elective nodal failure occurred in 2 patients (1.7%). Median follow-up was 38 months, median overall survival 20 months (95% confidence interval = 17.8-22.1 months), and 2-year survival 38.4%. In multivariate analysis, only total GTV (P=.026) and performance status (P=.016) significantly influenced survival. Conclusions: In this series of stage I to III small cell lung cancer patients treated with FDG-PET-based selective nodal irradiation total GTV is an independent risk factor for survival.

    Purpose: The aim of this study was to explore the characteristics derived from 18F-fluorodeoxyglucose (18F-FDG) PET image and assess its capacity in staging of esophageal squamous cell carcinoma (ESCC). Methods: 26 patients with newly diagnosed ESCC who underwent 18F-FDG PET scan were included in this study. Different image-derived indices including the standardized uptake value (SUV), gross tumor length, texture features and shape feature were considered. Taken the histopathologic examination as the gold standard, the extracted capacities of indices in staging of ESCC were assessed by Kruskal-Wallis test and Mann-Whitney test. Specificity and sensitivity for each of the studied parameters were derived using receiver-operating characteristic curves. Results: 18F-FDG SUVmax and SUVmean showed statistically significant capability in AJCC and TNM stages. Texture features such as ENT and CORR were significant factors for N stages(p=0.040, p=0.029). Both FDG PET Longitudinal length and shape feature Eccentricity (EC) (p≤0.010) provided powerful stratification in the primary ESCC AJCC and TNM stages than SUV and texture features. Receiver-operating-characteristic curve analysis showed that tumor textural analysis can capability M stages with higher sensitivity than SUV measurement but lower in T and N stages. Conclusion: The 18F-FDG image-derived characteristics of SUV, textural features and shape feature allow for good stratification AJCC and TNM stage in ESCC patients.

    Abstract Necrotizing enterocolitis (NEC) is the most common and frequently dangerous neonatal gastrointestinal disease. Studies have shown broad-spectrum antibiotics plus anaerobic antimicrobial therapy did not prevent the deterioration of NEC among very low birth preterm infants. However, few studies about this therapy which focused on full-term and near-term infant with NEC has been reported. The aim of this study was to evaluate the effect of broad-spectrum antibiotic plus metronidazole in preventing the deterioration of NEC from stage II to III in full-term and near-term infants. A retrospective cohort study based on the propensity score (PS) 1:1 matching was performed among the full-term and near-term infants with NEC (Bell stage ≥II). All infants who received broad-spectrum antibiotics were divided into 2 groups: group with metronidazole treatment (metronidazole was used ≥4 days continuously, 15 mg/kg/day) and group without metronidazole treatment. The depraved rates of stage II NEC between the 2 groups were compared. Meanwhile, the risk factors associated with the deterioration of stage II NEC were analyzed by case-control study in the PS-matched cases. A total of 229 infants met the inclusion criteria. Before PS-matching, we found the deterioration of NEC rate in the group with metronidazole treatment was higher than that in the group without metronidazole treatment (18.1% [28/155] vs 8.1% [6/74]; P = 0.048). After PS-matching, 73 pairs were matched, and the depraved rate of NEC in the group with metronidazole treatment was not lower than that in the group without metronidazole treatment (15.1% vs 8.2%; P = 0.2). Binary logistic regression analysis showed that sepsis after NEC (odds ratio [OR] 3.748, 95% confidence interval [CI] 1.171–11.998, P = 0.03), the need to use transfusion of blood products after diagnosis of NEC (OR 8.003, 95% CI 2.365–27.087, P = 0.00), and the need of longer time for nasogastric suction were risk factors

    Purpose: The safety and efficacy of skin-sparing mastectomy (SSM) with immediate reconstruction (IR) in patients with locally advanced breast cancer are unclear. The purpose of this study is to compare the outcomes of women with noninflammatory Stage III SSM with IR vs. non-SSM-treated women who underwent neoadjuvant chemotherapy and adjuvant radiation therapy (XRT). Methods and Materials: Between October 1997 and March 2010, 100 consecutive patients (40 SSM with IR vs. 60 non-SSM) with Stage III breast cancer received anthracycline- and/or taxane-based neoadjuvant chemotherapy, mastectomy, and adjuvant XRT. Clinical stage (SSM with IR vs. for non-SSM) was IIIA (75% vs. 67%), IIIB (8% vs. 18%), and IIIC (8% vs. 8%). Tumors greater than 5 cm were found in 74% vs. 69%; 97% of patients in both groups were clinically node positive; and 8% vs. 18% had T4b disease. Results: The time from initial biopsy to XRT was prolonged for SSM-IR patients (274 vs. 254 days, p = 0.04), and there was a trend toward XRT delay of more than 8 weeks (52% vs. 31%, p = 0.07) after surgery. The rate of complications requiring surgical intervention was higher in the SSM-IR group (37.5% vs. 5%, p < 0.001). The 2-year actuarial locoregional control, breast cancer-specific survival, and overall survival rates for SSM with IR vs. non-SSM were 94.7% vs. 97.4%, 91.5% vs. 86.3%, and 87.4% vs. 84.8%, respectively (p = not significant). Conclusions: In our small study with limited follow-up, SSM with IR prolonged overall cancer treatment time and trended toward delaying XRT but did not impair oncologic outcomes. Complication rates were significantly higher in this group. Longer follow-up is needed.

    Purpose: To determine intervals between surgery and adjuvant chemotherapy and radiation in patients treated with mastectomy with immediate expander-implant reconstruction, and to evaluate locoregional and distant control and overall survival in these patients. Methods and Materials: Between May 1996 and March 2004, 104 patients with Stage II-III breast cancer were routinely treated at our institution under the following algorithm: (1) definitive mastectomy with axillary lymph node dissection and immediate tissue expander placement, (2) tissue expansion during chemotherapy, (3) exchange of tissue expander for permanent implant, (4) radiation. Patient, disease, and treatment characteristics and clinical outcomes were retrospectively evaluated. Results: Median age was 45 years. Twenty-six percent of patients were Stage II and 74% Stage III. All received adjuvant chemotherapy. Estrogen receptor staining was positive in 77%, and 78% received hormone therapy. Radiation was delivered to the chest wall with daily 0.5-cm bolus and to the supraclavicular fossa. Median dose was 5040 cGy. Median interval from surgery to chemotherapy was 5 weeks, from completion of chemotherapy to exchange 4 weeks, and from exchange to radiation 4 weeks. Median interval from completion of chemotherapy to start of radiation was 8 weeks. Median follow-up was 64 months from date of mastectomy. The 5-year rate for locoregional disease control was 100%, for distant metastasis-free survival 90%, and for overall survival 96%. Conclusions: Mastectomy with immediate expander-implant reconstruction, adjuvant chemotherapy, and radiation results in a median interval of 8 weeks from completion of chemotherapy to initiation of radiation and seems to be associated with acceptable 5-year locoregional control, distant metastasis-free survival, and overall survival.

    NEXRAD's Multisensor Precipitation Estimator (MPE) product replaced the Stage III product started in October 2003 at the West Gulf River Forecast Center (WGRFC) where includes most of the Texas and New Mexico. The MPE is an integrated product of rain gauge, NEXRAD, and satellite (GOES) precipitation estimates. The main objective of MPE is to reduce both areal-mean bias error and local bias error. The overall improved quality of MPE over Stage 3 is evident at the WGRFC. However, so far, there is no quantitative evaluation in a relative long period (one year or more) of a large area. In this study, high quality and density of 50 raingauge networks (6 minutes temporal resolution) in the Upper Guadalupe River Basin, Central Texas are used to evaluate both the Stage III (years 2001 and 2002) and MPE (year 2004) products. In this study, we propose two types of comparison (1) directly compare collocated radar cell and gauge of all rainfall events and (2) only compare collocated radar cell and gauge of homogeneous/uniform rainfall events. To find uniform rainfall events, 6-mintutes raingauge rainfall were used to calculate the correlation coefficient (CC) and coefficient of variation (CV) of a hour among one central gauge and its surrounding gauges (>= 4). For a particular rainfall hour, when CV is < 0.5 and CC is > 0.5, or CV is <0.1, the rainfall event of this hour is thus selected as a uniform or homogeneous rainfall event. Our preliminary results of CC from all rainfall events and homogeneous rainfall events for year 2004 (MPE) are 0.79 and 0.96, respectively. This indicates an overall good quality of MPE product in comparison with raingauge rainfall, especially for the homogeneous rainfall events. Work is in progress.

    From 1982 to 1986, after radical surgery (S) for carcinoma of the rectum and rectosigmoid colon, 25 consecutive patients were entered into a Phase I/II study exploring adjuvant radiation (RT). The latter was given with a single fraction of whole abdomen (mid-body) irradiation (MBI), followed by conventional whole pelvis irradiation (WPI). The minimum follow-up time was 12 months, and the maximum was 44 months. There was escalation of the single MBI dose: 5 Gy in 11 patients, 6 Gy in two patients, and 8 Gy in 10 patients. The 2-year survival rate has been 100 and 45% for Stages B2 and C patients. Only 1/7 Astler-Coller Stage B2 patients failed; this failure was in the lungs. Seven of 15 patients with Stage C failed: one locally, three in the liver, and three in the lungs. Single MBI doses greater than 5 Gy have yielded a high incidence of intestinal obstruction when combined with routine WPI. Consequently, this combination requires both some modification and careful attention if used in future trials exploring new treatment approaches for colorectal cancer.

    The clinical characteristics and treatment outcome of patients with primary peritoneal serous papillary carcinoma (PPSC) (n = 22) was compared with stage III-IV papillary serous ovarian carcinoma (PSOC) patients (n = 63). There were no statistically significant differences between the PPSC and PSOC patients with regard to the mean age, menopausal status, parity, ascites fluid volume, proportion of stage IV disease, and the rate of optimal debulking achieved. The median disease-free interval was 15 and 18 months; the median survival was 21 and 26 months; and the 5-year survival was 18 and 24% for the PPSC and PSOC groups, respectively. The median survival time for patients with a residual tumor > or = 2 cm was 20.5 and 24 months, and for residual tumor > or = 2 cm was 46 and 41 months, in PPSC and PSOC patients, respectively. Survival was thus better, in both groups, when residual disease at the end of the operation was < 2 cm, though this was statistically significant only for PSOC (P < 0.02). We conclude that patients with PPSC should be treated as other stage II-IV PSOC patients. Combining optimal debulking with a platinum-based chemotherapy may offer the patient the most effective treatment. PMID:8774644

    Purpose: In preparation for a Phase III comparison of high-dose versus standard-dose radiation therapy, this Phase I/II study was initiated to establish the maximum tolerated dose of radiation therapy in the setting of concurrent chemotherapy, using three-dimensional conformal radiation therapy for non-small-cell lung cancer. Methods and Materials: Eligibility included patients with histologically proven, unresectable Stages I to III non-small-cell lung cancer. Concurrent chemotherapy consisted of paclitaxel, 50 mg/m{sup 2}, and carboplatin, AUC of 2, given weekly. The radiation dose was to be sequentially intensified by increasing the daily fraction size, starting from 75.25 Gy/35 fractions. Results: The Phase I portion of this study accrued 17 patients from 10 institutions and was closed in January 2004. After the initial 8 patients were accrued to cohort 1, the trial closed temporarily on September 26, 2002, due to reported toxicity. Two acute treatment-related dose-limiting toxicities (DLTs) were reported at the time: a case of grade 5 and grade 3 radiation pneumonitis. The protocol, therefore, was revised to de-escalate the radiation therapy dose (74 Gy/37 fractions). Patients in cohort 1 continued to develop toxicity, with 6/8 (75%) patients eventually developing grade >=3 events. Cohort 2 accrued 9 patients. There was one DLT, a grade 3 esophagitis, in cohort 2 in the first 5 patients (1/5 patients) and no DLTs for the next 2 patients (0/2 patients). Conclusions: The maximum tolerated dose was determined to be 74 Gy/37 fractions (2.0 Gy per fraction) using three-dimensional conformal radiation therapy with concurrent paclitaxel and carboplatin therapy. This dose level in the Phase II portion has been well tolerated, with low rates of acute and late lung toxicities.

    Background Methylation levels of long interspersed nucleotide elements (LINE-1) are representative of genome-wide methylation status and crucial in maintaining genomic stability and expression. Their prognostic impact on colon cancer patients receiving adjuvant chemotherapy has not been well established. We evaluated the association between LINE-1 methylation status and clinicopathologic features and postoperative oncological outcomes in stage III colon cancer patients. Materials and Methods 129 UICC stage III colon cancer patients who had received radical resection and FOLFOX adjuvant chemotherapy were enrolled. Global methylation was estimated by analyzing tumor LINE-1 methylation status using bisulfite-polymerase chain reaction (PCR) and pyrosequencing assay. Demographics, clinicopathological data, and postoperative outcomes were recorded by trained abstractors. Outcome measurements included postoperative recurrence and disease-free survival. Univariate, multivariate, and survival analyses were conducted to identify prognostic factors of oncological outcomes. Results The LINE-1 methylation of all 129 patients was measured on a 0–100 scale (mean 63.3; median 63.7, standard deviation 7.1), LINE-1 hypomethylation was more common in patients aged 65 years and above (61.7%±7.6% vs. 64.6±6.4, p=0.019) and those with post-therapeutic recurrence (61.7±7.4 vs 64.3±6.7, p=0.041). Considering risk adjustment, LINE-1 hypomethylation was found to be an independent risk factor of post-therapeutic recurrence (Adjusted OR=14.1, p=0.012). Kaplan-Meier analysis indicated that patients in the low methylation group had shorter period of disease free survival (p=0.01). In a stratified analysis that included 48 patients with post-therapeutic recurrence, it was found that those who experienced shorter period of disease free survival (≦6 months) appeared to have lower LINE-1 methylation levels than patients who reported of recurrence after 6 months (56.68±15.75 vs. 63.55±7

    Although rare, severe hidradenitis suppurativa (HS) of the anal, perianal, gluteal, thigh, and groin regions can evolve into squamous cell carcinoma (SCC). This usually does not occur until the HS has been present for more than 20 years. Malignant degeneration of HS in the axilla has not been reported. SCC has developed in dissecting cellulitis, acne conglobata, and pilonidal cysts (other members of the follicular tetrad). Whereas the male to female ratio of HS is 1:3, SCC in HS has a male to female ration of 5:1. The reasons behind malignant degeneration in HS are complex and might differ from the malignant degeneration causing Marjolin ulcers. It likely involves the presence of human papilloma virus (HPV) in affected areas (a rarity in the axilla), and impaired defensins, which combat HPV, in the skin of Hurley Stage III HS. In familial HS, the odds of developing SCC are likely greater because of independent loss-of-function mutations in the γ-secretase multiprotein complex, which regulates the Notch signaling pathway. Compromise of the Notch signaling pathway can undermine immune function and increase the risk of neoplastic development. Coincident SCC with use of tumor necrosis factor α blockers has been reported. I report a patient with long standing Hurley Stage III, familial HS, wwho developed metastatic SCC after 3 courses of infliximab and expired 11 months after the infliximab was started. A 47-year-old male presented with progressive HS since early adulthood. His stage III hidradenitis suppurativa (HS) involved his groin, legs buttocks, and perineal areas. Interestingly, his HS was familial; one daughter also suffered from HS. A pilonidal cyst had been excised in the past. He suffered from hypertension for which he took ramipril, 2.5 mg per day. He did not admit to smoking. He had undergone numerous surgeries and courses of clindamycin with rifampin and clindamycin with minocycline. He used pregablin among other stronger medications for pain control. He

    Purpose: To compare the quality of volumetric modulated arc therapy (VMAT) or intensity-modulated radiation therapy (IMRT) plans generated by an automated inverse planning system with that of dosimetrist-generated IMRT treatment plans for patients with stage III lung cancer. Methods and Materials: Two groups of 8 patients with stage III lung cancer were randomly selected. For group 1, the dosimetrists spent their best effort in designing IMRT plans to compete with the automated inverse planning system (mdaccAutoPlan); for group 2, the dosimetrists were not in competition and spent their regular effort. Five experienced radiation oncologists independently blind-reviewed and ranked the three plans for each patient: a rank of 1 was the best and 3 was the worst. Dosimetric measures were also performed to quantitatively evaluate the three types of plans. Results: Blind rankings from different oncologists were generally consistent. For group 1, the auto-VMAT, auto-IMRT, and manual IMRT plans received average ranks of 1.6, 2.13, and 2.18, respectively. The auto-VMAT plans in group 1 had 10% higher planning tumor volume (PTV) conformality and 24% lower esophagus V70 (the volume receiving 70 Gy or more) than the manual IMRT plans; they also resulted in more than 20% higher complication-free tumor control probability (P+) than either type of IMRT plans. The auto- and manual IMRT plans in this group yielded generally comparable dosimetric measures. For group 2, the auto-VMAT, auto-IMRT, and manual IMRT plans received average ranks of 1.55, 1.75, and 2.75, respectively. Compared to the manual IMRT plans in this group, the auto-VMAT plans and auto-IMRT plans showed, respectively, 17% and 14% higher PTV dose conformality, 8% and 17% lower mean lung dose, 17% and 26% lower mean heart dose, and 36% and 23% higher P+. Conclusions: mdaccAutoPlan is capable of generating high-quality VMAT and IMRT treatment plans for stage III lung cancer. Manual IMRT plans could achieve quality

    The intracellular pathogen Chlamydia trachomatis possesses a type III secretion (TTS) system believed to deliver a series of effector proteins into the inclusion membrane (Inc-proteins) as well as into the host cytosol with perceived consequences for the pathogenicity of this common venereal pathogen. Recently, small molecules were shown to block the TTS system of Yersinia pseudotuberculosis. Here, we show that one of these compounds, INP0400, inhibits intracellular replication and infectivity of C. trachomatis at micromolar concentrations resulting in small inclusion bodies frequently containing only one or a few reticulate bodies (RBs). INP0400, at high concentration, given at the time of infection, partially blocked entry of elementary bodies into host cells. Early treatment inhibited the localization of the mammalian protein 14-3-3β to the inclusions, indicative of absence of the early induced TTS effector IncG from the inclusion membrane. Treatment with INP0400 during chlamydial mid-cycle prevented secretion of the TTS effector IncA and homotypic vesicular fusions mediated by this protein. INP0400 given during the late phase resulted in the detachment of RBs from the inclusion membrane concomitant with an inhibition of RB to elementary body conversion causing a marked decrease in infectivity.

    Purpose To determine the optimal dose and schedule of anthracycline and taxane administration as adjuvant therapy for early-stage breast cancer. Patients and Methods A 2 × 2 factorial design was used to test two hypotheses: (1) that a novel continuous schedule of doxorubicin-cyclophosphamide was superior to six cycles of doxorubicin-cyclophosphamide once every 2 weeks and (2) that paclitaxel once per week was superior to six cycles of paclitaxel once every 2 weeks in patients with node-positive or high-risk node-negative early-stage breast cancer. With 3,250 patients, a disease-free survival (DFS) hazard ratio of 0.82 for each randomization could be detected with 90% power with two-sided α = .05. Overall survival (OS) was a secondary outcome. Results Interim analyses crossed the futility boundaries for demonstrating superiority of both once-per-week regimens and once-every-2-weeks regimens. After a median follow-up of 6 years, a significant interaction developed between the two randomization factors (DFS P = .024; OS P = .010) in the 2,716 patients randomly assigned in the original design, which precluded interpretation of the two factors separately. Comparing all four arms showed a significant difference in OS (P = .040) but not in DFS (P = .11), with all treatments given once every 2 weeks associated with the highest OS. This difference in OS seemed confined to patients with hormone receptor–negative/human epidermal growth factor receptor 2 (HER2) –negative tumors (P = .067), with no differences seen with hormone receptor–positive/HER2-negative (P = .90) or HER2-positive tumors (P = .40). Conclusion Patients achieved a similar DFS with any of these regimens. Subset analysis suggests the hypothesis that once-every-2-weeks dosing may be best for patients with hormone receptor–negative/HER2-negative tumors. PMID:25422488

    Purpose: Our institutional experience with the use of hyperfractionated radiation therapy (RT) alone or concurrently with chemotherapy (RT-CHT) in Stage III non-small-cell lung cancer was reviewed. Methods and Materials: Three phase III and two phase II studies included a total of 600 patients. Hyperfractionated RT alone was given to 127 patients, and hyperfractionated RT-CHT was given to 473 patients. RT doses were 64.8 Gy and 69.6 Gy (using 1.2 Gy twice daily) and 67.6 Gy (using 1.3 Gy twice daily). CHT consisted of concurrent administration of carboplatin and etoposide to 409 patients and concurrent administration of carboplatin and paclitaxel to 64 patients. Results: The median survival times were 19 months, 21 months, and 12 months for all, RT-CHT, and RT-only patients, respectively. The survival difference between the RT-CHT and RT group was significant (p < 0.0001). Four-year rates of local progression-free survival (LPFS) and distant metastasis-free survival (DMFS) were 29% and 35%, respectively, for the entire group. The RT-CHT group had significantly better LPFS rates than the RT group (31% for the RT-CHT group vs. 16% for the RT group; p = 0.0015) but not DMFS rates (36% for the RT-CHT group vs. 36% for the RT group, p = 0.0571). Acute high-grade esophagitis, pneumonitis, and hematological toxicities were seen most frequently and in 11%, 9%, and 12% of patients, respectively. Late high-grade esophageal and bronchopulmonary toxicity were each seen in 6% of patients. Conclusions: Compared to the majority of existing phase II and III studies, this study reconfirmed the excellent results achieved with concurrent RT-CHT, including low toxicity. Concurrent RT-CHT results in survival benefit primarily by increasing LPFS, not DMFS.

    Introduction. Gingival recession is an apical shift of the gingival margin with exposure of the root surface. This migration of the marginal tissue leads to esthetic concerns, dentin hypersensitivity, root caries, and cervical wear. It is, paradoxically, a common finding in patients with a high standard of oral hygiene, as well as in periodontally untreated populations with poor oral hygiene. Changing the topography of the marginal soft tissue in order to facilitate plaque control is a common indication for root coverage procedures and forms a major aspect of periodontal plastic surgeries. The regeneration of a new connective tissue attachment to denuded root surface is by allowing the selective coronal regrowth of periodontal ligament cells while excluding the gingival tissues from the root during wound healing by means of a barrier membrane. Case Presentation. This case reports a two-stage surgical technique for treatment of Miller's class III defect using free gingival autograft and type I absorbable collagen membrane (BioMend®, Zimmer Dental, USA)§. Conclusions. The 6-month follow-up of the case showed a significant increase in attached gingiva suggesting it as a predictable alternative in the treatment of Millers class III defects.

    Purpose: To determine the influence of measured comorbidity in Radiation Therapy Oncology Group (RTOG) combined modality therapy (CMT) study enrollment in Stage III non-small cell lung cancer (NSCLC). Methods and Materials: One hundred and seventy-one patients with a Karnofsky Performance Score {>=}70 and clinical Stage III NSCLC were analyzed retrospectively for comorbidity, RTOG study eligibility, and enrollment at initial consultation. Effect of comorbidity scores (Cumulative Illness Rating Scale) were tested on patient selection for CMT, RTOG enrollment, and overall survival. Results: Comorbidity (Grade 4; p < 0.005) and use of radiation only (p {<=} 0.001) were associated with inferior survival independent of other factors. Patient selection for CMT was affected by age ({>=}70, p < 0.001), comorbidity (severity index [SI]> 2, p = 0.001), and weight loss (>5%, p = 0.001). Thirty-three patients (19%) were enrolled in a CMT RTOG study (Group 1). Forty-nine patients (29%) were eligible but not enrolled (Group 2), and 57 (33%) were ineligible (Group 3). The most common ineligibility reasons were weight loss (67%) and comorbidity in the exclusion criteria of the RTOG studies (63%). Group 1 patients were the youngest (p = 0.02), with the lowest comorbidity scores (p < 0.001) and SI (p < 0.001) compared with Groups 2 and 3. Group 3 patients were the oldest with the most unfavorable comorbidity profile. Comorbidity scores (SI >2; p = 0.006) and age ({>=}70; p = 0.05) were independent factors influencing RTOG study enrollment in patients meeting study eligibility requirements (Groups 1 and 2). Conclusions: Comorbidity scales could be useful in stratification of patients in advanced lung cancer trials and interpretation of results particularly regarding the elderly population.

    Purpose: A possible association between thyroid diseases (TD) and breast cancer (BC) has been debated. We examined prevalence and development of TD in women after multimodal treatment for Stage II/III BC compared with women from a general population. Secondarily, we explored the impact of two different radiotherapy (RT) techniques (standardized field arrangements vs. computed tomography [CT]-based dose planning) on TD in BC patients examined 35-120 months after primary BC treatment. Methods and Materials: A total of 403 BC patients completed a questionnaire about TD and had blood samples taken for analyses of thyroid function. All had undergone postoperative RT with or without (2%) adjuvant systemic treatment. The results in the BC patients were compared with a cancer-free, age-matched control group from a general population (CGr). Results: There was higher prevalence of self-reported hypothyroidism in the BC patients as compared with the CGr (18% vs. 6%, p < 0.001). The raised prevalence was predominantly due to a substantial increase in the development of hypothyroidism after BC diagnosis, whereas the prevalence of hypothyroidism before BC diagnosis was similar to that observed in the CGr. Patients treated with CT-based RT showed a trend for increased post-BC development of hypothyroidism as compared with those treated with standardized field arrangements (p = 0.08). Conclusions: Hypothyroidism is significantly increased in women after multimodal treatment for Stage II/III BC. Radiation to the thyroid gland may be a contributing factor. BC patients should be routinely screened for hypothyroidism.

    Purpose: To determine the optimal sequence of postoperative adjuvant chemotherapy and radiotherapy in patients with Stage II or III rectal cancer. Methods and Materials: A total of 308 patients were randomized to early (n = 155) or late (n = 153) radiotherapy (RT). Treatment included eight cycles of chemotherapy, consisting of fluorouracil 375 mg/m{sup 2}/day and leucovorin 20 mg/m{sup 2}/day, at 4-week intervals, and pelvic radiotherapy of 45 Gy in 25 fractions. Radiotherapy started on Day 1 of the first chemotherapy cycle in the early RT arm and on Day 1 of the third chemotherapy cycle in the late RT arm. Results: At a median follow-up of 121 months for surviving patients, disease-free survival (DFS) at 10 years was not statistically significantly different between the early and late RT arms (71% vs. 63%; p = 0.162). A total of 36 patients (26.7%) in the early RT arm and 49 (35.3%) in the late RT arm experienced recurrence (p = 0.151). Overall survival did not differ significantly between the two treatment groups. However, in patients who underwent abdominoperineal resection, the DFS rate at 10 years was significantly greater in the early RT arm than in the late RT arm (63% vs. 40%; p = 0.043). Conclusions: After the long-term follow-up duration, this study failed to show a statistically significant DFS advantage for early radiotherapy with concurrent chemotherapy after resection of Stage II and III rectal cancer. Our results, however, suggest that if neoadjuvant chemoradiation is not given before surgery, then early postoperative chemoradiation should be considered for patients requiring an abdominoperineal resection.

    Concurrent chemoradiotherapy (CCRT) has been considered to be the standard of care for locally advanced unresectable stage III non-small-cell lung cancer (LA-NSCLC). Whether consolidation chemotherapy (CCT) following CCRT is able to further improve the clinical outcome remains unclear. We therefore undertook a meta-analysis to compare the two regimens for LA-NSCLC. A literature search was performed through PubMed, Embase, Cochrane Library and Chinese Biology Medicine, from their inception to November, 2015. Irrelevant studies were excluded using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. Our primary endpoint was overall survival (OS), which was defined as the time from randomisation until death from any cause; the secondary endpoint was progression-free survival (PFS). All analyses were by intention-to-treat. Five phase III randomized controlled trials with 958 patients were included in the present meta-analysis. The results were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Compared with CCRT, CCT after CCRT was not associated with statistically significant differences in OS (OR=1.24; 95% CI: 0.89–1.72; P=0.21) or PFS (OR=1.16; 95% CI: 0.74–1.83; P=0.53), but increased the risk of toxicity, including infection (P=0.02), pneumonitis (P=0.003) and treatment-related death (P=0.04). There were no significant differences in terms of benefit according to particular patient characteristics, such as age, gender, performance status, tumor histology or clinical stage. Thus, the present study failed to support the use of CCT after CCRT over CCRT alone, as there was no significant OS and PFS benefit for LA-NSCLC patients, but the use of CCT after CCRT resulted in increased toxicity.

    1983-06-01

    Specific Sertoli--Sertoli and Sertoli--germ-cell contacts and/or junctions were investigated employing micrographs used to reconstruct serially a model of a rat stage V Sertoli cell. The Sertoli--Sertoli junctional contact areas occurred in a belt-like arrangement near the base of the Sertoli cell. This configuration is consistent with their proposed function as a sealing element limiting the passage of materials toward the tubular lumen. Sertoli ectoplasmic specializations also formed a continuous belt, or band, around the reconstructed cell at the junctional contact area. Eighteen Sertoli--Sertoli tubulobulbar complexes were found; some (12 in number) invaginated the reconstructed cell, while others (6) emanated from it. Of 37 round germ cells that were sectioned in their entirety and adjoined the reconstructed cell, 23 displayed desmosome-gap junctions with either the reconstructed cell or an adjoining cell. Since there were multiple junctions connecting some germ cells to Sertoli cells, the total number of junctions was much greater (35). Desmosome-gap junctions of the Sertoli cell were numerous connecting pachytene spermatocytes, less numerous connecting type B spermatogonia, and even less numerous connecting step 5 spermatids; and none was seen joining Sertoli cells with elongate spermatids. Most desmosome-gap junctions join germ cells to the body of the Sertoli cell at its basal aspect. Their numbers and position indicate that they play a role in the maintenance of the integrity of the seminiferous epithelium and may provide a route for cell-to-cell communication. Ectoplasmic specializations of the reconstructed cell were seen facing only 3 of 37 round germ cells, and 7 ectoplasmic specializations from adjoining Sertoli cells faced these germ cells, all of which were step 5 spermatids. That there were no ectoplasmic specializations facing pachytene cells indicates that ectoplasmic specializations are not acquired as these cells pass through Sertoli

    Purpose: The clinical benefits and risks of dose escalation (DE) for stage III non–small-cell lung cancer (NSCLC) remain uncertain despite the results from Radiation Therapy Oncology Group (RTOG) protocol 0617. There is significant heterogeneity of practice, with many clinicians prescribing intermediate dose levels between the 0617 study arms of 60 and 74 Gy. This study investigated whether this strategy is associated with any survival benefits/risks by analyzing a large multi-institutional database. Methods and Materials: An individual patient database of stage III NSCLC patients treated with radical intent concurrent chemoradiation therapy was created (13 institutions, n=1274 patients). Patients were divided into 2 groups based on tumor Biological Effective Dose at 10 Gy (BED 10): those receiving standard dose (SD; n=552), consisting of 72Gy ≤ BED 10 ≤ 76.8 Gy (eg 60-64 Gy/30-32 fractions [fr]), and those receiving intermediate dose (ID; n=497), consisting of 76.8Gy < BED 10 < 100.8 Gy (eg >64 Gy/32 fr and <74 Gy/37 fr), with lower-dose patients (n=225) excluded from consideration. Patients were then matched using propensity scores, leading to 2 matched groups of 196 patients. Outcomes were compared using various statistics including interquartile range (IQR), Kaplan-Meier curves, and adjusted Cox regression analysis. Results: Matched groups were found to be balanced except for N stage (more N3 disease in SD), median treatment year (SD in 2003; ID in 2007), platinum and taxane chemotherapy (SD in 28%; ID in 39%), and median follow-up (SD were 89 months; ID were 40 months). Median dose fractionation was 60 Gy/30 fr in SD (BED 10 IQR: 72.0-75.5 Gy) and 66 Gy/33 fr (BED 10 IQR: 78.6-79.2 Gy) in ID. Survival curves for SD and ID matched cohorts were statistically similar (P=.27); however, a nonstatistically significant trend toward better survival for ID was observed after 15 months (median survival SD: 19.3 months; ID: 21.0

    Patients with chronic kidney disease (CKD) are three times more likely to have myocardial infarction (MI) and suffer from increased morbidity and higher mortality. Traditional and unique risk factors are prevalent and constitute challenges for the standard of care. However, CKD patients have been largely excluded from clinical trials and little evidence is available to guide evidence-based treatment of coronary artery disease in patients with CKD. Our objective was to assess whether a difference exists in the management of MI (ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction) among patients with normal kidney function, CKD stage III-V, and end-stage renal disease (ESRD) patients. We conducted a retrospective cohort study on patients admitted to Staten Island University Hospital for the diagnosis of MI between January 2005 and December 2012. Patients were assigned to one of three groups according to their kidney function: Data collected on the medical management and the use of statins, platelet inhibitors, beta-blockers, and angiotensin converting enzyme inhibitors/angiotensin receptor blockers were compared among the three cohorts, as well as medical interventions including: catheterization and coronary artery bypass graft (CABG) when indicated. Chi-square test was used to compare the proportions between nominal variables. Binary logistic analysis was used in order to determine associations between treatment modalities and comorbidities, and to account for possible confounding factors. Three hundred and thirty-four patients (mean age 67.2±13.9 years) were included. In terms of management, medical treatment was not different among the three groups. However, cardiac catheterization was performed less in ESRD when compared with no CKD and CKD stage III-V (45.6% vs 74% and 93.9%) (P<0.001). CABG was performed in comparable proportions in the three groups and CABG was not associated with the degree of CKD (P=0.078) in binary

    The aim of this study was to investigate the pattern, amount, and distribution of postsurgical relapse in skeletal Class III patients treated with two-jaw surgery (TJS) using conventional three-stage method (CTM) and surgery-first approach (SFA). A total of 38 patients who underwent the nonextraction approach and TJS (LeFort I posterior impaction and mandibular setback) were divided into CTM and SFA groups (all n = 19/group). Lateral cephalograms were taken before treatment (T0), at 1 month before surgery (T1), immediately after surgery (T2), and at debonding (T3) for CTM patients and at T0, T2, and T3 stages for SFA patients. Cephalometric measurements and statistical analyses were performed. There were no significant differences in the cephalometric variables at all stages except maxillary incisor inclination (U1-UOP) and overbite at T0 between 2 groups. They also did not exhibit significant differences in the amounts of surgical movement except for advancement of the maxilla. The mandible in both groups was rotated slightly clockwise by surgery and counterclockwise during T2-T3 without a significant difference. Distribution of cases with "high relapse" (>30%) and "low relapse" (<30%) of the mandible differed for 2 groups (P < 0.05). SFA group had more "high relapse" cases than CTM group (57.9% versus 26.3%). Postsurgical relapse of the mandible had a positive relationship with the amount of mandibular setback in SFA group (P < 0.01) and clockwise rotation of the proximal segment of the mandible in both groups (P < 0.05 and P < 0.01). The results suggest that SFA might be an effective alternative to CTM if the cause of "high relapse" including amounts of mandibular setback and clockwise rotation of the proximal segment of the mandible during surgery can be controlled.

    Purpose: We describe individual, area, and provider characteristics associated with care patterns for early-stage breast cancer in Appalachian counties of Kentucky, North Carolina, Ohio, and Pennsylvania. Methods: Cases of stages I to III breast cancer from 2006 to 2008 were linked to Medicare claims occurring within 1 year of diagnosis. Rates of guideline-concordant endocrine therapy (n = 1,429), chemotherapy (n = 1,480), and radiation therapy (RT) after breast-conserving surgery were studied; RT was studied in women age ≥ 70 years with stage I estrogen receptor (ER) –positive/progesterone receptor (PR) –positive cancer, for whom RT was optional (n = 1,108), and in all others, for whom RT was guideline concordant (n = 1,422). Univariable and multivariable analyses were performed. Independent variables included age, race, county-level economic status, state, surgeon graduation year and volume, comorbidity, diagnosis year, Medicaid/Medicare dual status, histology, tumor size, tumor sequence, positive lymph nodes, ER/PR status, stage, trastuzumab use, and surgery type. Results: Population mean age was 74 years; 97% were white. For endocrine therapy, chemotherapy, and RT, guideline concordance was 76%, 48%, and 83%, respectively. Where it was optional, 77% received RT. Guideline-concordant endocrine therapy was lower in North Carolina versus Pennsylvania (odds ratio [OR], 0.60; 95% CI, 0.41 to 0.88) and higher if surgeon graduated between 1984 and 1988 versus ≥ 1989 (OR, 1.58; 95% CI, 1.06 to 2.34). Guideline-concordant chemotherapy varied significantly by state, county-level economic status, and surgeon volume. In guideline-concordant RT, lower surgeon volume (v highest) predicted RT use (OR, 1.63; 95% CI, 1.61 to 2.36). In optional RT, North Carolina residence (v Pennsylvania; OR, 0.29; 95% CI, 0.17 to 0.48) and counties with higher economic status (OR, 0.61; 95% CI, 0.40 to 0.94) predicated RT omission. Conclusion: Notable variation in care by geographic

    Background Fluorouracil-based preoperative chemoradiotherapy has become the standard treatment for stage II/III rectal cancer. In order to improve the overall survival (OS) and disease-free survival (DFS), we added oxaliplatin to the standard treatment, and compared the effectiveness of these two treatment patterns. Methods A total of 206 patients enrolled in the prospective study had histologically confirmed rectal cancer of clinical stage II/III during July 2007 to July 2010. They were randomized into the experimental group received oxaliplatin and capecitabine in combination with radiotherapy, and the control group received capecitabine in combination with radiotherapy. All patients received surgery in 6−10 weeks after chemoradiotherapy and adjuvant chemotherapy with mFOLFOX6. The primary endpoints were DFS and OS, and the secondary endpoints included toxicity, compliance, and histopathological response. Results The 3-year OS in the experimental group and the control group was 90.29% vs. 86.41% (P>0.05), and the 3-year DFS was 80.58% vs. 69.90% (P>0.05). The pathological complete remission (pCR) rates were 23.30% and 19.42%, respectively (P=0.497). The 3-year local recurrence rates were 4.85% vs. 5.83% (P=0.694), and the 3-year distant metastasis rates were 16.50% and 28.16%, respectively (P=0.045). There were no significant differences in most grade 3−4 toxicities between two groups, however, grade 3−4 diarrhea occurred in 16.50% (17/103) of the experimental group, compared with 6.80% (7/103) of the control group (P=0.030). Also, the total grade 3−4 acute toxicity showed a significant difference (10.68% vs. 21.36%, P=0.037). Conclusions The experimental treatment did not lead significantly improved OS and DFS, and thus longer follow-up is warranted for our patient cohort. Adding oxaliplatin to capecitabine-based preoperative chemoradiotherapy can significantly reduce metastasis, but has only minimal impact on local recurrence. Although grade 3−4

    Purpose: The prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients with non-small-cell lung cancer (NSCLC) is unclear. The present study investigated the effect of tumor cell expression of FGF-2 on the outcome of 60 patients irradiated for Stage II-III NSCLC. Methods and Materials: The effect of FGF-2 expression and 13 additional factors on locoregional control (LRC), metastasis-free survival (MFS), and overall survival (OS) were retrospectively evaluated. These additional factors included age, gender, Karnofsky performance status, histologic type, histologic grade, T and N category, American Joint Committee on Cancer stage, surgery, chemotherapy, pack-years, smoking during radiotherapy, and hemoglobin during radiotherapy. Locoregional failure was identified by endoscopy or computed tomography. Univariate analyses were performed with the Kaplan-Meier method and the Wilcoxon test and multivariate analyses with the Cox proportional hazard model. Results: On univariate analysis, improved LRC was associated with surgery (p = .017), greater hemoglobin levels (p = .036), and FGF-2 negativity (p <.001). On multivariate analysis of LRC, surgery (relative risk [RR], 2.44; p = .037), and FGF-2 expression (RR, 5.06; p <.001) maintained significance. On univariate analysis, improved MFS was associated with squamous cell carcinoma (p = .020), greater hemoglobin levels (p = .007), and FGF-2 negativity (p = .001). On multivariate analysis of MFS, the hemoglobin levels (RR, 2.65; p = .019) and FGF-2 expression (RR, 3.05; p = .004) were significant. On univariate analysis, improved OS was associated with a lower N category (p = .048), greater hemoglobin levels (p <.001), and FGF-2 negativity (p <.001). On multivariate analysis of OS, greater hemoglobin levels (RR, 4.62; p = .002) and FGF-2 expression (RR, 3.25; p = .002) maintained significance. Conclusions: Tumor cell expression of FGF-2 appeared to be an independent negative predictor

    Purpose: To quantify the impact of preradiotherapy 18F-fluoro-2-deoxyglucose positron-emission tomography (FDG-PET) on treatment strategy and radiotherapy planning for patients with Stage I/II Hodgkin disease included in a large prospective multicenter study. Patients and Methods: Conventional computed tomography and FDG-PET were performed just before the planned radiotherapy. The radiotherapy plan was first elaborated under blinded conditions for FDG-PET data. Then, the medical staff was asked to confirm or not confirm the treatment strategy and, if appropriate, to modify the radiotherapy plan based on additional information from FDG-PET. Results: Between January 2004 and January 2006, 137 patients were included (124 were available for analysis) in 11 centers (108 adults, 16 children). All but 1 patient had received chemotherapy before inclusion. Prechemotherapy work-up included FDG-PET for 61 patients, and data were available for elaboration of the first radiotherapy plan. Based on preradiotherapy FDG-PET data, the radiotherapy was cancelled in 6 patients (4.8%), and treatment plan modifications occurred in 16 patients (12.9%): total dose (11 patients), CTV volume (5 patients), number of beam incidences (6 patients), and number of CTV (6 patients). The concordance between the treatment strategies with or without preradiotherapy FDG-PET was 82.3%. Concordance results were not significantly different when prechemotherapy PET-CT information was available. Conclusion: Preradiotherapy FDG-PET for treatment planning in Hodgkin lymphoma may lead to significant modification of the treatment strategy and the radiotherapy planning in patients with Stage I or II Hodgkin disease, even in those who have undergone FDG-PET as part of the prechemotherapy work-up.

    Purpose: To determine the factors associated with the use of radiation therapy and associated survival outcomes in early-stage marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT). Methods and Materials: We extracted data on adult patients with stage I/II MALT lymphoma diagnoses between 1998 and 2010 recorded in the Surveillance, Epidemiology, and End Results (SEER) database. We studied factors associated with radiation therapy administration in a logistic regression model and described the cumulative incidence of lymphoma-related death (LRD) according to receipt of the treatment. The association of radiation therapy with survival was explored in multivariate models with adjustment for immortal time bias. Results: Of the 7774 identified patients, 36% received radiation therapy as part of the initial course of treatment. Older patients; black or Hispanic men; white, Hispanic, and black women; and socioeconomically disadvantaged and underinsured patients had a significantly lower chance of receiving radiation therapy. Radiation therapy administration was associated with a lower chance of LRD in most sites. In cutaneous, ocular, and salivary MALT lymphomas, the 5-year estimate of LRD after radiation therapy was 0%. The association of radiation therapy with overall survival in different lymphoma sites was heterogeneous, and statistically significant in cutaneous (hazard ratio 0.45, P=.009) and ocular (hazard ratio 0.47, P<.0001) locations after multivariate adjustment. Conclusions: Demographic factors are associated with the use of radiation therapy in MALT lymphoma. Clinicians should be sensitive to those disparities because the administration of radiation therapy may be associated with improved survival, particularly in cutaneous and ocular lymphomas.

    Purpose: To evaluate the safety and feasibility of concurrent radiation therapy and paclitaxel-based adjuvant chemotherapy, given either weekly or every 3 weeks, after adjuvant doxorubicin and cyclophosphamide (AC). Methods and Materials: After definitive breast surgery and AC chemotherapy, 40 patients with operable Stage II or III breast cancer received protocol-based treatment with concurrent paclitaxel and radiation therapy. Paclitaxel was evaluated on 2 schedules, with treatment given either weekly x 12 weeks (60 mg/m{sup 2}), or every 3 weeks x 4 cycles (135-175 mg/m{sup 2}). Radiation fields and schedules were determined by the patient's surgery and pathology. The tolerability of concurrent therapy was evaluated in cohorts of 8 patients as a phase I study. Results: Weekly paclitaxel treatment at 60 mg/m{sup 2} per week with concurrent radiation led to dose-limiting toxicity in 4 of 16 patients (25%), including 3 who developed pneumonitis (either Grade 2 [1 patient] or Grade 3 [2 patients]) requiring steroids. Efforts to eliminate this toxicity in combination with weekly paclitaxel through treatment scheduling and CT-based radiotherapy simulation were not successful. By contrast, dose-limiting toxicity was not encountered among patients receiving concurrent radiation with paclitaxel given every 3 weeks at 135-175 mg/m{sup 2}. However, Grade 2 radiation pneumonitis not requiring steroid therapy was seen in 2 of 24 patients (8%) treated in such a fashion. Excessive radiation dermatitis was not observed with either paclitaxel schedule. Conclusions: Concurrent treatment with weekly paclitaxel and radiation therapy is not feasible after adjuvant AC chemotherapy for early-stage breast cancer. Concurrent treatment using a less frequent paclitaxel dosing schedule may be possible, but caution is warranted in light of the apparent possibility of pulmonary injury.

    Biomarkers can help to identify patients with early-stages or locally advanced non-small cell lung cancer (NSCLC) who have high risk of relapse and poor prognosis. To correlate the expression of seven biomarkers involved in DNA synthesis and repair and in cell division with clinical outcome, we consecutively collected 82 tumour tissues from radically resected NSCLC patients. The following biomarkers were investigated using IHC and qRT-PCR: excision repair cross-complementation group 1 (ERCC1), breast cancer 1 (BRCA1), ribonucleotide reductase subunits M1 and M2 (RRM1 and RRM2), subunit p53R2, thymidylate synthase (TS), and class III beta-tubulin (TUBB3). Gene expression levels were also validated in an available NSCLC microarray dataset. Multivariate analysis identified the protein overexpression of RRM2 and TS as independent prognostic factors of shorter overall survival (OS). Kaplan-Meier analysis showed a trend in shorter OS for patients with RRM2, TS, and ERCC1, BRCA1 overexpressed tumours. For all of the biomarkers except TUBB3, the OS trends relative to the gene expression levels were in agreement with those relative to the protein expression levels. The NSCLC microarray dataset showed RRM2 and TS as biomarkers significantly associated with OS. This study suggests that high expression levels of RRM2 and TS might be negative prognostic factors for resected NSCLC patients. PMID:26663950

    As the optimal treatment for primary mediastinal large B-cell lymphoma (PMBCL) remains undefined, we evaluated outcomes of patients treated with standard and dose-intense rituximab-chemotherapy (R-CT) with and without radiotherapy (RT). We retrospectively identified 28 patients with stage I-II PMBCL in our lymphoma database, re-reviewed pathology slides and scored interim or post-chemotherapy PET/CTs using the Deauville scale. Fourteen patients received RT (36-45 Gy) preceded by either six cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or 12 weeks of rituximab, etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone and bleomycin (R-VACOP-B) with median follow-up of 94 months. Fourteen patients received 4-8 cycles of dose-adjusted etoposide, vincristine, doxorubicin, cyclophosphamide and rituximab (DA-EPOCH-R) with median follow-up of 38 months; one of these received RT (36 Gy) due to post-chemotherapy PET/CT Deauville score 4. Following R-CT and RT or DA-EPOCH-R, 5-year and 3-year FFP and OS were both 100%. Both R-CHOP/R-VACOP-B with RT and DA-EPOCH-R demonstrate excellent outcomes. PMID:26159046

    Eighty-three patients treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) and adjuvant irradiation for Stage I, grade III adenocarcinoma of the endometrium were reviewed. At 5 years, the overall survival was 71%, and the disease-free survival (excluding patients dying of intercurrent disease) was 79%. The failure rates for pelvis alone, pelvis plus distant, and distant alone were 4.8%, 4.8%, and 10.8%, respectively. The most common site of failure was the upper abdomen; 12% of all patients had a failure at this site, either alone or in conjunction with failure at another site. The 24% rate of failure in 50 patients receiving a preoperative implant and external irradiation was not significantly different from the 15% failure rate in 33 patients whose adjuvant irradiation consisted of a preoperative implant only. For the patients who had both an implant and external irradiation, the dose of external irradiation had no correlation with the rate of failure. In contrast, the number of milligram-hours delivered to the uterus by the preoperative implant had a strong inverse correlation with the rate of failure, both for patients receiving an implant only and for those receiving an implant plus external irradiation. The data suggest the following: (1) a high-intensity preoperative uterine implant may be an important adjunct to surgery; and (2) external pelvic irradiation in addition to the implant does not seem to be any more beneficial than an implant alone.

    Purpose: To establish the feasibility and tolerability of gefitinib (ZD1839, Iressa) with radiation (RT) or concurrent chemoradiation (CRT) with cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). Patients and Methods: In this multicenter Phase I study, 5 patients with unresectable NSCLC received 250 mg gefitinib daily starting 1 week before RT at a dose of 63 Gy (Step 1). After a first safety analysis, 9 patients were treated daily with 250 mg gefitinib plus CRT in the form of RT and weekly CDDP 35 mg/m{sup 2} (Step 2). Gefitinib was maintained for up to 2 years until disease progression or toxicity. Results: Fourteen patients were assessed in the two steps. In Step 1 (five patients were administered only gefitinib and RT), no lung toxicities were seen, and there was no dose-limiting toxicity (DLT). Adverse events were skin and subcutaneous tissue reactions, limited to Grade 1-2. In Step 2, two of nine patients (22.2%) had DLT. One patient suffered from dyspnea and dehydration associated with neutropenic pneumonia, and another showed elevated liver enzymes. In both steps combined, 5 of 14 patients (35.7%) experienced one or more treatment interruptions. Conclusions: Gefitinib (250 mg daily) in combination with RT and CDDP in patients with Stage III NSCLC is feasible, but CDDP likely enhances toxicity. The impact of gefitinib on survival and disease control as a first-line treatment in combination with RT remains to be determined.

    Background Vitamin D receptor activators reduce albuminuria, and may improve survival in chronic kidney disease (CKD). Animal studies suggest that these pleiotropic effects of vitamin D may be mediated by suppression of renin. However, randomized trials in humans have yet to establish this relationship. Methods In a randomized, placebo-controlled, double-blinded crossover study, the effect of oral paricalcitol (2 μg/day) was investigated in 26 patients with non-diabetic, albuminuric stage III-IV CKD. After treatment, plasma concentrations of renin (PRC), angiotensin II (AngII) and aldosterone (Aldo) were measured. GFR was determined by 51Cr-EDTA clearance. Assessment of renal NO dependency was performed by infusion of NG-monomethyl-L-arginine (L-NMMA). Albumin excretion rate (AER) was analyzed in 24-h urine and during 51Cr-EDTA clearance. Results Paricalcitol did not alter plasma levels of renin, AngII, Aldo, or urinary excretion of sodium and potassium. A modest reduction of borderline significance was observed in AER, and paricalcitol abrogated the albuminuric response to L-NMMA. Conclusions In this randomized, placebo-controlled trial paricalcitol only marginally decreased AER and did not alter circulating levels of renin, AngII or Aldo. The abrogation of the rise in albumin excretion by paricalcitol during NOS blockade may indicate that favourable modulation of renal NO dependency could be involved in mediating reno-protection and survival benefits in CKD.

    The purpose of this work was to determine the risk of local-regional failure following post-mastectomy radiotherapy and the incidence of complications associated with such treatment. The authors retrospectively analyzed the results in 309 patients with Stage I--III invasive breast cancer treated with post-mastectomy radiation therapy between 1975 and 1985. The median radiotherapy dose was 45 Gy in 1.8 to 2.25 Gy fractions. One hundred forty-seven (48%) of the patients received adjuvant systemic chemotherapy with 115 (78%) of these receiving a CMF-based or doxorubicin-containing regime. The median follow-up time of surviving patients was 130 months (range, 28 to 191 months) after mastectomy. Seventeen patients (6%) developed a local-regional failure at an interval of 4 to 87 months after radiotherapy. Moderate or severe complications related to radiotherapy and requiring treatment were uncommon. Symptomatic radiation pneumonitis occurred in four patients (1.3%), arm edema in 18 (5.8%), and brachial plexopathy in 2 (0.6%). The authors conclude that post-operative radiotherapy is a safe and effective means of reducing local-regional failure following mastectomy. The efficacy of post-mastectomy radiotherapy in improving survival should be addressed in new large randomized controlled studies. 33 refs., 1 fig., 3 tabs.

    Purpose: To investigate, in a phase III randomized trial, whether postoperative external-beam irradiation to the standard pelvic field improves the recurrence-free interval and overall survival (OS) in women with Stage IB cervical cancers with negative lymph nodes and certain poor prognostic features treated by radical hysterectomy and pelvic lymphadenectomy. Methods and Materials: Eligible patients had Stage IB cervical cancer with negative lymph nodes but with 2 or more of the following features: more than one third (deep) stromal invasion, capillary lymphatic space involvement, and tumor diameter of 4 cm or more. The study group included 277 patients: 137 randomized to pelvic irradiation (RT) and 140 randomized to observation (OBS). The planned pelvic dose was from 46 Gy in 23 fractions to 50.4 Gy in 28 fractions. Results: Of the 67 recurrences, 24 were in the RT arm and 43 were in the OBS arm. The RT arm showed a statistically significant (46%) reduction in risk of recurrence (hazard ratio [HR] = 0.54, 90% confidence interval [CI] = 0.35 to 0.81, p = 0.007) and a statistically significant reduction in risk of progression or death (HR = 0.58, 90% CI = 0.40 to 0.85, p = 0.009). With RT, 8.8% of patients (3 of 34) with adenosquamous or adenocarcinoma tumors recurred vs. 44.0% (11 of 25) in OBS. Fewer recurrences were seen with RT in patients with adenocarcinoma or adenosquamous histologies relative to others (HR for RT by histology interaction = 0.23, 90% CI = 0.07 to 0.74, p = 0.019). After an extensive follow-up period, 67 deaths have occurred: 27 RT patients and 40 OBS patients. The improvement in overall survival (HR = 0.70, 90% CI = 0.45 to 1.05, p = 0.074) with RT did not reach statistical significance. Conclusions: Pelvic radiotherapy after radical surgery significantly reduces the risk of recurrence and prolongs progression-free survival in women with Stage IB cervical cancer. RT appears to be particularly beneficial for patients with adenocarcinoma or

    Purpose: The optimal combination of chemotherapy and radiotherapy (RT) and the role of consolidation chemotherapy in patients with locally advanced non-small-cell lung cancer (NSCLC) are unknown. Topotecan is active against NSCLC, can safely be combined with RT at effective systemic doses, and can be given by continuous infusion, making it an attractive study agent against locally advanced NSCLC. Methods and Materials: In this pilot study, 20 patients were treated with infusion topotecan 0.4 mg/m{sup 2}/d with three-dimensional conformal RT to 63 Gy both delivered Monday through Friday for 7 weeks. Patients without progression underwent consolidation chemotherapy with etoposide and a platinum agent for one cycle followed by two cycles of docetaxel. The study endpoints were treatment response, time to progression, survival, and toxicity. Results: Of the 20 patients, 19 completed induction chemoradiotherapy and 13 completed consolidation. Of the 20 patients, 18 had a partial response and 1 had stable disease after induction chemoradiotherapy. The 3-year overall survival rate was 32% (median, 18 months). The local and distant progression-free survival rate was 30% (median, 21 months) and 58% (median, not reached), respectively. Three patients developed central nervous system metastases, 1 within 228 days, 1 within 252 days, and 1 within 588 days. Three patients had pulmonary emboli. Therapy was well tolerated with 1 of 20 developing Grade 4 lymphopenia. Grade 3 hematologic toxicity was seen in 17 of 20 patients but was not clinically significant. Other Grade 3 toxicities included esophagitis in 3, esophageal stricture in 2, fatigue in 8, and weight loss in 1. Grade 3 pneumonitis occurred in 6 of 20 patients. Conclusion: Continuous infusion topotecan with RT was well tolerated and active in the treatment of poor-risk patients with unresectable Stage III NSCLC.

  6. Health-related quality of life in survivors of stage I-II breast cancer: randomized trial of post-operative conventional radiotherapy and hypofractionated tomotherapy

    Background Health-related quality of life (HRQOL) assessment is a key component of clinical oncology trials. However, few breast cancer trials comparing adjuvant conventional radiotherapy (CR) and hypofractionated tomotherapy (TT) have investigated HRQOL. We compared HRQOL in stage I-II breast cancer patients who were randomized to receive either CR or TT. Tomotherapy uses an integrated computed tomography scanner to improve treatment accuracy, aiming to reduce the adverse effects of radiotherapy. Methods A total of 121 stage I–II breast cancer patients who had undergone breast conserving surgery (BCS) or mastectomy (MA) were randomly assigned to receive either CR or TT. CR patients received 25 × 2 Gy over 5 weeks, and BCS patients also received a sequential boost of 8 × 2 Gy over 2 weeks. TT patients received 15 × 2.8 Gy over 3 weeks, and BCS patients also received a simultaneous integrated boost of 15 × 0.6 Gy over 3 weeks. Patients completed the EORTC QLQ-C30 and BR23 questionnaires. The mean score (± standard error) was calculated at baseline, the end of radiotherapy, and at 3 months and 1, 2, and 3 years post-radiotherapy. Data were analyzed by the 'intention-to-treat' principle. Results On the last day of radiotherapy, patients in both treatment arms had decreased global health status and functioning scores; increased fatigue (clinically meaningful in both treatment arms), nausea and vomiting, and constipation; decreased arm symptoms; clinically meaningful increased breast symptoms in CR patients and systemic side effects in TT patients; and slightly decreased body image and future perspective. At 3 months post-radiotherapy, TT patients had a clinically significant increase in role- and social-functioning scores and a clinically significant decrease in fatigue. The post-radiotherapy physical-, cognitive- and emotional-functioning scores improved faster in TT patients than CR patients. TT patients also had a better long-term recovery

    Purpose: We investigated the efficacy and safety of weekly low-dose docetaxel and cisplatin therapy concurrent with conventionally fractionated radiation in patients with technically resectable stage III-IV squamous cell carcinoma of the head and neck. Methods and Materials: Between March 2004 and October 2011, we enrolled 117 patients, of whom 116 were analyzable (43 had oropharyngeal cancer, 54 had hypopharyngeal cancer, and 19 had laryngeal cancer), and 85 (73%) had stage IV disease. Radiation consisted of 66 Gy in 33 fractions. Docetaxel, 10 mg/m{sup 2}, followed by cisplatin, 20 mg/m{sup 2}, administered on the same day were given once a week for 6 cycles. The primary endpoint was overall complete response (CR) rate after chemoradiation therapy. Human papillomavirus (HPV) DNA in oropharyngeal cancer was examined by PCR. Results: Of 116 patients, 82 (71%) completed treatment per protocol; 102 (88%) received the full radiation therapy dose; and 90 (78%) and 12 (10%) patients received 6 and 5 chemotherapy cycles, respectively. Overall CR rate was 71%. After median follow-up of 50.9 months (range: 15.6-113.9 months for surviving patients), 2-year and 4-year overall survival rates were 82% and 68%, respectively. Cumulative 2-year and 4-year local failure rates were 27% and 28%, respectively, whereas distant metastasis rates were 15% and 22%, respectively. HPV status in oropharyngeal cancer was not associated with treatment efficacy. Acute toxicity included grade 3 and 4 in-field mucositis in 73% and 5% of patients, respectively, whereas myelosuppression and renal injury were minimal. No patients died of toxicity. Feeding tube dependence in 8% and tracheostomy in 1% of patients were evident at 2 years postchemoradiation therapy in patients who survived without local treatment failure. Conclusions: Local control and survival with this regimen were satisfactory. Although acute toxicity, such as mucositis, was common, late toxicity, such as laryngoesophageal

    Purpose To compare and contrast the patterns of failure in patients with locally advanced squamous cell oropharyngeal cancers undergoing curative-intent treatment with primary surgery or radiotherapy +/- chemotherapy. Methods and materials Two hundred and thirty-three patients with stage III or IV oropharyngeal squamous cell carcinoma who underwent curative-intent treatment from 2006-2012, were reviewed. The median length of follow-up for patients still alive at the time of analysis was 4.4 years. Data was collected retrospectively from a chart review. Results One hundred and thirty-nine patients underwent primary surgery +/- adjuvant therapy, and 94 patients underwent primary radiotherapy +/- chemotherapy (CRT). Demographics were similar between the two groups, except primary radiotherapy patients had a higher age-adjusted Charleston co-morbidity score (CCI). Twenty-nine patients from the surgery group recurred; 15 failed distantly only, seven failed locoregionally, and seven failed both distantly and locoregionally. Twelve patients recurred who underwent chemoradiotherapy; ten distantly alone, and two locoregionally. One patient who underwent radiotherapy (RT) alone failed distantly. Two and five-year recurrence-free survival rates for patients undergoing primary RT were 86.6% and 84.9% respectively. Two and five-year recurrence-free survival rates for primary surgery was 80.9% and 76.3% respectively (p=0.21). There was no significant difference in either treatment when they were stratified by p16 status or smoking status. Conclusions Our analysis does not show any difference in outcomes for patients treated with primary surgery or radiotherapy. Although the primary pattern of failure in both groups was distant metastatic disease, some local failures may be preventable with careful delineation of target volumes, especially near the base of skull region.

    Tumor necrosis factor (TNF)-α-induced protein 8 (TIPE) is a recently identified protein that is considered to be associated with various malignancies, including esophageal, breast and pancreatic cancer; however, the importance of TIPE in gastric cancer (GC) remains unknown. Decoy receptor 3 (DcR3) is a member of the tumor necrosis factor receptor superfamily that is expressed in digestive system neoplasms. The expression of DcR3 is regulated by the mitogen-activated protein kinase (MAPK)/MAPK kinase/extracellular signal-regulated kinase (ERK) signaling pathway. Reverse transcription-polymerase chain reaction was performed to detect the expression of TIPE, ERK and DcR3 in the pathological and tumor-adjacent normal gastric tissues of 30 patients that demonstrated stage III gastric adenocarcinoma. The expression and distribution of the TIPE protein was examined using immunohistochemistry, and the clinical significance and expression levels of DcR3 and ERK1/2 were evaluated. The expression of TIPE, ERK1/2 and DcR3 in the tumor tissues of GC was significantly increased compared with paracarcinoma tissues (P<0.05). In addition, TIPE expression positively correlated with DcR3 and ERK1 levels (r=0.538 and r=0.462, respectively; P<0.05). There was no statistical difference between tumor tissues from patients with varying age, gender, differentiation or lymph node metastasis (P>0.05). TIPE may be vital in the progression of GC. TIPE may be associated with the expression of DcR3 and ERK1/2, which may be involved in the cell apoptosis of GC. The present study elucidates the potential function of TIPE as a novel marker and therapeutic target for GC. PMID:26998086

    Purpose: This study was designed to assess the 3-year experience with superselective intraarterial chemotherapy prior to definitive treatment for stages III and IV squamous cell carcinomas of the mouth. Methods: Twenty-two patients prospectively received superselective intraarterial chemotherapy using relatively low-dose cisplatin via a transfemoral approach. The locations of the tumors were the tongue (n= 12), gingiva (n= 5), buccal mucosa (n= 2), hard palate (n= 1), floor of the mouth (n= 1), and lip (n= 1). After intraarterial chemotherapy, 21 patients underwent surgery (n= 14), radiation therapy (n= 6), or both (n= 1). The survival rate of 25 patients who underwent surgery with/without radiation therapy until 1992 at Kumamoto University Hospital was also evaluated as a historical control. The survival curve was calculated with the Kaplan-Meier method, and the statistical difference between survival curves was determined with the generalized Wilcoxon test. Results: The overall response rate was 95% [complete response (tumor completely resolved), 24%; partial response (tumor reduction {>=}50%), 71%]. Fifty-two intraarterial infusions were performed without any catheter-related complications. Mild and transient local toxicity such as edema or mucositis of the infused area was relatively common. One patient died of renal failure from cisplatin. After a median follow-up of 20 months (range 2-41 months), the estimated 3-year survival rate for patients who underwent intraarterial chemotherapy plus surgery was 91%. The survival of the patients who underwent intraarterial chemotherapy plus surgery tended to be longer than that of the historical control. Conclusions: Early tumor reduction without delay of subsequent treatments can be obtained by intraarterial chemotherapy while minimizing complications and possibly improving survival. Further investigations of long-term survival with larger series need to be performed.

    Objective To assess the efficacy of neoadjuvant systemic therapy (NST) at increasing the rate of successful breast-conserving therapy (BCT) in triple negative breast cancer. Background Inducing tumor regression to permit BCT is often cited to support administration of NST. To quantify this benefit, we conducted a surgical companion study to CALGB40603, a randomized phase II, 2×2 factorial trial of neoadjuvant paclitaxel ± carboplatin ± bevacizumab (B) followed by doxorubicin plus cyclophosphamide ± B in stage II–III triple negative breast cancer. Methods Before and after NST, treating surgeons evaluated BCT candidacy by clinico-radiographic criteria; surgery performed was at surgeon and patient discretion. We measured (1) conversion rates from BCT-ineligible to BCT-eligible, (2) surgical choices in BCT candidates, and (3) rates of successful BCT with tumor-free margins. Results Four hundred four patients were assessable for surgical outcomes. Two hundred nineteen (54%) were BCT candidates before NST. One hundred ninety-seven (90%) remained BCT candidates after NST, of whom 138 (70%) chose BCT, which was successful in 130 (94%). Of 185 (46%) who were not BCT candidates before NST, 78 (42%) converted to candidates with NST. Of these, 53 (68%) chose BCT with a 91% (48/53) success rate. The overall BCT-eligibility rate rose from 54% to 68% (275/404) with NST. Addition of carboplatin, B, or both increased conversion rates. Conclusions This is the first study to document prospectively a 42% conversion rate from BCT-ineligible to BCT-eligible, resulting in a 14% absolute increase in BCT eligibility. BCT was successful in 93% of patients who opted for it, but 31% of BCT-eligible patients still chose mastectomy. PMID:26222764

    Colorectal cancer is commonly treated with 5-fluorouracil and 5-formyltetrahydrofolate (leucovorin). Metabolic action of leucovorin requires several enzymatic steps that are dependent on expression of corresponding coding genes. To identify folate pathway genes with possible impact on leucovorin metabolism, a retrospective study was performed on 193 patients with stage III colorectal cancer. Relative expression of 22 genes putatively involved in leucovorin transport, polyglutamation and metabolism was determined in tumor and mucosa samples using quantitative real-time polymerase chain reaction. After surgery, patients received adjuvant 5-fluorouracil-based bolus chemotherapy with leucovorin during six months, and were followed for 3 to 5 years. Cox regression analysis showed that high tumoral expression of the genes SLC46A1/PCFT (proton-coupled folate transporter) and SLC19A1/RFC-1 (reduced folate carrier 1) correlated significantly (p < 0.001 and p < 0.01, respectively) with a decreased risk of recurrent disease, measured as disease-free survival (DFS). These two genes are involved in the transport of folates into the cells and each functions optimally at a different pH. We conclude that SLC46A1/PCFT and SLC19A1/RFC-1 are associated with DFS of patients with colorectal cancer and hypothesize that poor response to 5-fluorouracil plus leucovorin therapy in some patients may be linked to low expression of these genes. Such patients might need a more intensified therapeutic approach than those with high gene expression. Future prospective studies will determine if the expression of any of these genes can be used to predict response to leucovorin. PMID:26193446

    The frequency and clinical profile of patients with stage III non-small cell lung cancer harboring KRAS mutations have not yet been well documented. Here, we analyzed hotspot KRAS mutations using high-resolution melting analyses in tumor specimens from patients who received chemoradiotherapy between January 2001 and December 2010 at the National Cancer Center Hospital. The associations between the presence of KRAS mutations and the response rate, relapse-free survival, first relapse sites, survival post-progression and overall survival were investigated. A total of 274 non-squamous non-small cell lung cancer patients received chemoradiotherapy at our hospital. After excluding 121 patients for whom tumor specimens were not available and 34 patients with EGFR mutations, the remaining 119 patients were included in the analysis. KRAS mutations were found at a frequency of 13%. Patients with KRAS mutations had a shorter median relapse-free survival (6.1 vs 10.9 months) and a lower response rate (63% vs 81%). As for the first relapse site, patients with KRAS mutations had fewer local relapses (8% vs 23%) and more brain metastases (46% vs 12%). After disease progression, patients with KRAS mutations had a significantly shorter median survival post-progression (2.5 vs 7.3 months, P = 0.028) and median overall survival (15.1 vs 29.1 months, P = 0.022). Our results suggested that KRAS mutation could be associated with a reduced efficacy of chemoradiotherapy and a shortened survival time. PMID:26177347

    Purpose: Concomitant chemoradiotherapy is the standard treatment of locally advanced, nonresectable, head-and-neck squamous cell carcinoma. However, the optimal chemotherapy regimen is still controversial. The objective of this Phase II study was to evaluate the feasibility and efficacy of a concomitant treatment using tegafur-uracil, leucovorin, carboplatin, and radiotherapy. Methods and Materials: A total of 77 patients with head-and-neck squamous cell carcinoma Stage III and IVA were enrolled between October 2003 and July 2005. Of the 77 patients, 72 were eligible. They were treated with tegafur-uracil (300 mg/m{sup 2}/d) and leucovorin (75 mg/d) from Days 1 to 19 and from Days 29 to 47 and carboplatin (70 mg/m{sup 2} intravenously for 4 consecutive days), in three cycles every 21 days. Conventional radiotherapy was delivered to a total dose of 70 Gy in 35 fractions. Results: With a mean follow-up of 22.8 months, the 3-year locoregional control, overall survival and disease-free survival actuarial rate was 33.1%, 41.9%, and 27.2%, respectively. The compliance of the treatment was correct. The main acute toxicity was mucositis, with 62% Grade 3-4. Three patients (4.2%) died of acute toxicity. The incidence and severity of late toxicity was acceptable, with 32% Grade 3 and no Grade 4 toxicity. Conclusion: The protocol of concomitant chemoradiotherapy using tegafur-uracil, leucovorin, and carboplatin for locally advanced unresectable head-and-neck squamous cell carcinoma is feasible. The compliance was correct. The incidence and severity of the acute and late toxicities were acceptable, but not improved. The efficacy of this regimen seems equivalent to the main protocols of concurrent chemoradiotherapy. It represents a possible alternative for patients without an intravenous catheter.

Our results suggested that KRAS mutation could be associated with a reduced efficacy of chemoradiotherapy and a shortened survival time. PMID:26177347

    N-Ethyl-N-nitrosourea (ENU) was evaluated as part of the Stage III trial for the rat Pig-a gene mutation assay. Groups of six- to eight-week-old male Sprague Dawley (SD) or Fischer 344 (F344) rats were given 28 daily doses of the phosphate buffered saline vehicle, or 2.5, 5, or 10 mg/kg ENU, and evaluated for a variety of genotoxicity endpoints in peripheral blood, spleen, liver, and colon. Blood was sampled predose (Day-1) and at various time points up to Day 57. Pig-a mutant frequencies were determined in total red blood cells (RBCs) and reticulocytes (RETs) as RBC(CD592-) and RET(CD592-) frequencies. Consistent with the results from a reference laboratory, RBC(CD592-) and RET(CD592-) frequencies increased in a dose and time-dependent manner, producing significant increases at all doses by Day 15, with similar frequencies seen in both rat strains. ENU also induced small but significant increases in % micronucleated RETs on Days 4 and 29. No significant increases in micronuclei were seen in the liver or colon of the ENU-treated SD rats. Hprt and Pig-a lymphocyte mutation assays conducted on splenocytes from Day 56 F344 rats detected two- to fourfold stronger responses for Hprt than Pig-a mutations. Results from the in vivo Comet assay in SD rats at Day 29 showed generally weak increases in DNA damage in all tissues evaluated. The results with ENU indicate that the Pig-a RET and RBC assays are reproducible, transferable, and complement other genotoxicity endpoints that could potentially be integrated into 28-day repeat dose rat studies.

    Purpose: To verify the feasibility of, and quantify the risk of, pneumonitis from locoregional radiotherapy (RT) after high-dose dense chemotherapy with epirubicin and paclitaxel with peripheral blood progenitor cell support in patients with high-risk Stage II-III breast cancer. Methods and Materials: Treatment consisted of a mobilizing course of epirubicin 150 mg/m{sup 2}, preceded by dexrazoxane (Day 1), paclitaxel 175 mg/m{sup 2} (Day 2), and filgrastim; followed by three courses of epirubicin 150 mg/m{sup 2}, preceded by dexrazoxane (Day 1), paclitaxel 400 mg/m{sup 2} (Day 2), and peripheral blood progenitor cell support and filgrastim, every 16-19 days. After chemotherapy, patients were treated with locoregional RT, which included the whole breast or the chest wall, axilla, and supraclavicular area. Results: Overall, 64 of 69 patients were evaluable. The interval between the end of chemotherapy and the initiation of RT was at least 1.5-2 months (mean 2). No treatment-related death was reported. After a median follow-up of 27 months from RT (range 5-77 months), neither clinically relevant radiation pneumonitis nor congestive heart failure had been reported. Minor and transitory lung and cardiac toxicities were observed. Conclusion: Sequential high doses of epirubicin, preceded by dexrazoxane, and paclitaxel did not adversely affect the tolerability of locoregional RT in breast cancer patients. The risk of pneumonitis was not affected by the use of sequential paclitaxel with an interval of at least 1.5-2 months between the end of chemotherapy and the initiation of RT. Long-term follow-up is needed to define the risk of cardiotoxicity in these patients.

    Purpose: A Phase I study was conducted to determine the maximal tolerated dose and the dose-limiting toxicity (DLT) of oxaliplatin (OXA) combined with capecitabine and radiotherapy as adjuvant treatment in patients with operable rectal cancer. Patients and Methods: A total of 21 patients with Stage II or III rectal adenocarcinoma after curative surgery were treated with radiotherapy to a total dose of 50 Gy in 5 weeks. OXA was administered at a dosage of 40 (n = 6), 50 (n = 3),60 (n = 3), 70 (n = 3), or 80 mg/m{sup 2} (n = 6) once a week for 2 weeks (first cycle) followed by a second cycle after a 7-day break. Capecitabine at a fixed dose of 1,300 mg/m{sup 2}/d was administered orally at the same schedule as for OXA. DLT was defined as Grade 3 or 4 hematologic and nonhematologic toxicity. Results: Grade 1-3 leukopenia, diarrhea, and nausea/vomiting were the most common toxic side effects, and most were Grade 1-2. A DLT was first observed in 1 of 3 patients at 40 mg/m{sup 2} (Grade 3 diarrhea) but was not observed in the next 3 patients at the same level or in patients who received a dose level of 50-70 mg/m{sup 2}. At 80 mg/m{sup 2}, DLT occurred in 3 of 6 patients (1 Grade 4 leukopenia and 2 Grade 3 diarrhea). Conclusions: OXA combined with a fixed dose of capecitabine at 625 mg/m{sup 2} twice daily by mouth plus radiotherapy in the adjuvant setting was tolerable and clinically feasible. The maximal tolerated dose of OXA in this setting was 80 mg/m{sup 2}, comparable to the maximal tolerated dose of OXA in the neoadjuvant setting.

    Introduction The majority of stage III patients with non-small cell lung cancer (NSCLC) are unsuitable for concurrent chemoradiotherapy, the non-surgical gold standard of care. As the alternative treatment options of sequential chemoradiotherapy and radiotherapy alone are associated with high local failure rates, various intensification strategies have been employed. There is evidence to suggest that altered fractionation using hyperfractionation, acceleration, dose escalation, and individualisation may be of benefit. The MAASTRO group have pioneered the concept of ‘isotoxic’ radiotherapy allowing for individualised dose escalation using hyperfractionated accelerated radiotherapy based on predefined normal tissue constraints. This study aims to evaluate whether delivering isotoxic radiotherapy using intensity modulated radiotherapy (IMRT) is achievable. Methods and analysis Isotoxic IMRT is a multicentre feasibility study. From June 2014, a total of 35 patients from 7 UK centres, with a proven histological or cytological diagnosis of inoperable NSCLC, unsuitable for concurrent chemoradiotherapy will be recruited. A minimum of 2 cycles of induction chemotherapy is mandated before starting isotoxic radiotherapy. The dose of radiation will be increased until one or more of the organs at risk tolerance or the maximum dose of 79.2 Gy is reached. The primary end point is feasibility, with accrual rates, local control and overall survival our secondary end points. Patients will be followed up for 5 years. Ethics and dissemination The study has received ethical approval (REC reference: 13/NW/0480) from the National Research Ethics Service (NRES) Committee North West—Greater Manchester South. The trial is conducted in accordance with the Declaration of Helsinki and Good Clinical Practice (GCP). The trial results will be published in a peer-reviewed journal and presented internationally. Trial registration number NCT01836692; Pre-results. PMID:27084277

    Purpose: A Phase I study to determine a recommended dose of thoracic radiotherapy using accelerated hyperfractionation for unresectable non-small-cell lung cancer was conducted. Methods and Materials: Patients with unresectable Stage III non-small-cell lung cancer were treated intravenously with carboplatin (area under the concentration curve 2) and paclitaxel (40 mg/m{sup 2}) on Days 1, 8, 15, and 22 with concurrent twice-daily thoracic radiotherapy (1.5 Gy per fraction) beginning on Day 1 followed by two cycles of consolidation chemotherapy using carboplatin (area under the concentration curve 5) and paclitaxel (200 mg/m{sup 2}). Total doses were 54 Gy in 36 fractions, 60 Gy in 40 fractions, 66 Gy in 44 fractions, and 72 Gy in 48 fractions at Levels 1 to 4. The dose-limiting toxicity, defined as Grade {>=}4 esophagitis and neutropenic fever and Grade {>=}3 other nonhematologic toxicities, was monitored for 90 days. Results: Of 26 patients enrolled, 22 patients were assessable for response and toxicity. When 4 patients entered Level 4, enrollment was closed to avoid severe late toxicities. Dose-limiting toxicities occurred in 3 patients. They were Grade 3 neuropathy at Level 1 and Level 3 and Grade 3 infection at Level 1. However, the maximum tolerated dose was not reached. The median survival time was 28.6 months for all patients. Conclusions: The maximum tolerated dose was not reached, although the dose of radiation was escalated to 72 Gy in 48 fractions. However, a dose of 66 Gy in 44 fractions was adopted for this study because late toxicity data were insufficient.

    Colorectal cancer is commonly treated with 5-fluorouracil and 5-formyltetrahydrofolate (leucovorin). Metabolic action of leucovorin requires several enzymatic steps that are dependent on expression of corresponding coding genes. To identify folate pathway genes with possible impact on leucovorin metabolism, a retrospective study was performed on 193 patients with stage III colorectal cancer. Relative expression of 22 genes putatively involved in leucovorin transport, polyglutamation and metabolism was determined in tumor and mucosa samples using quantitative real-time polymerase chain reaction. After surgery, patients received adjuvant 5-fluorouracil-based bolus chemotherapy with leucovorin during six months, and were followed for 3 to 5 years. Cox regression analysis showed that high tumoral expression of the genes SLC46A1/PCFT (proton-coupled folate transporter) and SLC19A1/RFC-1 (reduced folate carrier 1) correlated significantly (p < 0.001 and p < 0.01, respectively) with a decreased risk of recurrent disease, measured as disease-free survival (DFS). These two genes are involved in the transport of folates into the cells and each functions optimally at a different pH. We conclude that SLC46A1/PCFT and SLC19A1/RFC-1 are associated with DFS of patients with colorectal cancer and hypothesize that poor response to 5-fluorouracil plus leucovorin therapy in some patients may be linked to low expression of these genes. Such patients might need a more intensified therapeutic approach than those with high gene expression. Future prospective studies will determine if the expression of any of these genes can be used to predict response to leucovorin. PMID:26193446

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2-4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2-4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2-4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

    Esophageal cancer is a leading cause of cancer-related deaths worldwide, and the 5-year relative survival rate remains less than 20% in the United States. The treatment of esophageal cancer should be stage specific for better clinical outcomes. Recent treatment paradigms tend to involve a multimodality approach to management, which includes surgical resection and preoperative or definitive chemoradiation therapy. Accurate pretreatment staging of esophageal cancer is integral for assessing operability and determining a suitable treatment plan. The American Joint Committee on Cancer (AJCC) and the Union for International Cancer Control (UICC) have published the seventh edition of the staging manual for cancer in the esophagus and esophagogastric junction. Unlike the sixth edition, the revised staging manual is data driven and harmonized with the staging of stomach cancer. Improvements include new definitions for the anatomic classifications Tis, T4, regional lymph node, N, and M and the addition of nonanatomic cancer characteristics (histopathologic cell type, histologic grade, and cancer location). Given the recent increase in the incidence of adenocarcinoma of the distal esophagus, esophagogastric junction, and gastric cardia, the staging of tumors in the esophagogastric junction has been addressed. Radiologists must understand the details of the seventh edition of the AJCC-UICC staging system for esophageal cancer and use appropriate imaging modalities, such as computed tomography (CT), endoscopic ultrasonography, and positron emission tomography/CT, for initial staging.

    Background Age 45 years is used as a cutoff in the staging of well-differentiated thyroid cancer (WDTC) as it represents the median age of most datasets. The aim of this study was to determine a statistically optimized age threshold using a large dataset of patients treated at a comprehensive cancer center. Methods Overall, 1807 patients with a median follow-up of 109 months were included in the study. Recursive partitioning was used to determine which American Joint Committee on Cancer (AJCC) variables were most predictive of disease-specific death, and whether a different cutoff for age would be found. From the resulting tree, a new age cutoff was picked and patients were restaged using this new cutoff. Results The 10-year disease-specific survival (DSS) by Union for International Cancer Control (AJCC/UICC) stage was 99.6, 100, 96, and 81 % for stages I–IV, respectively. Using recursive partitioning, the presence of distant metastasis was the most powerful predictor of DSS. For M0 patients, age was the next most powerful predictor, with a cutoff of 56 years. For M1 patients, a cutoff at 54 years was most predictive. Having reviewed the analysis, age 55 years was selected as a more robust age cutoff than 45 years. The 10-year DSS by new stage (using age 55 years as the cutoff) was 99.2, 98, 100, and 74 % for stages I–IV, respectively. Conclusion A change in age cutoff in the AJCC/UICC staging for WDTC to 55 years would improve the accuracy of the system and appropriately prevent low-risk patients being overstaged and overtreated.

    The V/III ratio in the initial growth stage of metalorganic chemical vapor deposition has an important influence on the quality of a GaN epilayer grown on a low-temperature AlN buffer layer and c-plane sapphire substrate. A weaker yellow luminescence, a narrower half-width of the X-ray diffraction peak, and a higher electron mobility result when a lower V/III ratio is taken. The intensity of in situ optical reflectivity measurements indicates that the film surface is rougher at the beginning of GaN growth, and a longer time is needed for the islands to coalesce and for a quasi-two dimensional mode growth to start. A comparison of front- and back-illuminated photoluminescence spectra confirms that many threading dislocations are bent during the initial stage, leading to a better structural quality of the GaN layer.

    Purpose The primary objective of this study was to determine whether carboplatin, paclitaxel, and sorafenib (CPS) improve overall survival (OS) compared with carboplatin and paclitaxel (CP) in chemotherapy-naive patients with metastatic melanoma. Patients and Methods In this double-blind, randomized, placebo-controlled phase III study, all patients received carboplatin at area under the [concentration-time] curve 6 and paclitaxel 225 mg/m2 intravenously once every 21 days with random assignment to sorafenib 400 mg orally twice per day on days 2 through 19 every 21 days or placebo. The primary end point was OS, and secondary end points included progression-free survival, objective tumor response, and toxicity. Results In all, 823 patients were enrolled over 34 months. At final analysis, the median OS was 11.3 months (95% CI, 9.8 to 12.2 months) for CP and 11.1 months (95% CI, 10.3 to 12.3 months) for CPS; the difference in the OS distribution was not statistically significant by the stratified log-rank test, stratified on American Joint Committee on Cancer (AJCC) stage, Eastern Cooperative Oncology Group (ECOG) performance status, and prior therapy (P = .878). Median progression-free survival was 4.9 months for CPS and 4.2 months for CP (P = .092, stratified log-rank test). Response rate was 20% for CPS and 18% for CP (P = .427). More patients on the CPS arm had grade 3 or higher toxicities (84% v 78%; P = .027), with increased rash, hand-foot syndrome, and thrombocytopenia accounting for most of the difference. Conclusion Sorafenib does not improve OS when given in combination with CP for chemotherapy-naive patients with metastatic melanoma. This study establishes benchmark end points for the CP regimen in first-line therapy of metastatic melanoma. PMID:23248256

    An important hallmark of CRC is the evasion of immune surveillance. HLA-G is a negative regulator of host’s immune response. Overexpression of HLA-G protein in primary tumour CRC tissues has already been associated to worse prognosis; however a definition of the role of immunogenetic host background is still lacking. Germline polymorphisms in the 3’UTR region of HLA-G influence the magnitude of the protein by modulating HLA-G mRNA stability. Soluble HLA-G has been associated to 3’UTR +2960 Ins/Ins and +3035 C/T (lower levels) and +3187 G/G (high levels) genotypes. HLA-G 3’UTR SNPs have never been explored in CRC outcome. The purpose of this study was to investigate if common HLA-G 3’UTR polymorphisms have an impact on DFS and OS of 253 stage II-III CRC patients, after primary surgery and ADJ-CT based on FL. The 3’UTR was sequenced and SNPs were analyzed for their association with survival by Kaplan-Meier and multivariate Cox models; results underwent internal validation using a resampling method (bootstrap analysis). In a multivariate analysis, we estimated an association with improved DFS in Ins allele (Ins/Del +Ins/Ins) carriers (HR 0.60, 95% CI 0.38–0.93, P = 0.023) and in patients with +3035 C/T genotype (HR 0.51, 95% CI 0.26–0.99, P = 0.045). The +3187 G/G mutated carriers (G/G vs A/A+A/G) were associated to a worst prognosis in both DFS (HR 2.46, 95% CI 1.19–5.05, P = 0.015) and OS (HR 2.71, 95% CI 1.16–6.63, P = 0.022). Our study shows a prognostic and independent role of 3 HLA-G 3’UTR SNPs, +2960 14-bp INDEL, +3035 C>T, and +3187 A>G. PMID:26633805

    In solid tumors, human leucocyte antigen (HLA)-A2 has been suggested to be a risk factor and a negative prognostic factor. The HLA-A2 allele in Scandinavia has a high prevalence; it decreases with latitude and also with ovarian cancer mortality in Europe. Furthermore, an association of the HLA-A2 allele with severe prognosis in serous adenocarcinoma of the ovary in stages III-IV was found. Thirty-two unrelated Swedish women with relapsing or progressive ovarian cancer were analysed for the genotypes at the HLA-A, HLA-B, HLA-Cw, and HLA-DRB1 loci by the polymerase chain reaction/sequence-specific primer method. The frequencies of HLA alleles of healthy Swedish bone marrow donors provided by the coordinating centre of the Bone Marrow Donors Worldwide Registries, Leiden, the Netherlands were used as controls. When this cohort of epithelial ovarian cancer patients was compared with healthy Swedish donors, the frequency of HLA-A1 and HLA-A2 gene/phenotype appears, although not statistically significant, to be increased in patients with ovarian carcinoma, while HLA-A3 was decreased. HLA-A2 homozygotes were twofold higher in patients. The A2-B8 haplotype was significantly increased (corrected P value). A2-B5, A2-B15, A2-DRB1*03, A2-DRB1*04, A2-B15-Cw3, and A2-B8-DRB1*03 had odds ratio as well as the level of the lower confidence interval above 1 and significant P value only when considered as single, non-corrected analysis. HLA-B15 and HLA-Cw3 were only present in HLA-A2-positive patients showing that the HLA-A2-HLA-Cw3 and HLA-B15 haplotypes were segregated. In this selected cohort with advanced disease, there are indications of an unusual overrepresentation of HLA class I and II genes/haplotypes as well as segregation for the HLA-A2-HLA-Cw3 and HLA-B15 haplotypes. These findings are presented as a descriptive analysis and need further investigations on a larger series of ovarian cancer patients to establish prognostic associations. PMID:17661908

    Purpose: To assess the clinical applicability of a protocol evaluated in a previously reported phase II study of concurrent chemoradiotherapy followed by consolidation chemotherapy with bi-weekly docetaxel and carboplatin in patients with stage III, unresectable, non-small-cell lung cancer (NSCLC). Methods and Materials: Between January 2000 and March 2006, 116 previously untreated patients with histologically proven, stage III NSCLC were treated with concurrent chemoradiotherapy. Radiation therapy was administered in 2-Gy daily fractions to a total dose of 60 Gy in combination with docetaxel, 30 mg/m{sup 2}, and carboplatin at an area under the curve value of 3 every 2 weeks during and after radiation therapy. Results: The median survival time for the entire group was 25.5 months. The actuarial 2-year and 5-year overall survival rates were 53% and 31%, respectively. The 3-year cause-specific survival rate was 60% in patients with stage IIIA disease, whereas it was 35% in patients with stage IIIB disease (p = 0.007). The actuarial 2-year and 5-year local control rates were 62% and 55%, respectively. Acute hematologic toxicities of Grade {>=}3 severity were observed in 20.7% of patients, while radiation pneumonitis and esophagitis of Grade {>=}3 severity were observed in 2.6% and 1.7% of patients, respectively. Conclusions: The feasibility of the protocol used in the previous phase II study was reconfirmed in this series, and excellent treatment results were achieved.

    Necrotizing enterocolitis (NEC) is the most common and frequently dangerous neonatal gastrointestinal disease. Studies have shown broad-spectrum antibiotics plus anaerobic antimicrobial therapy did not prevent the deterioration of NEC among very low birth preterm infants. However, few studies about this therapy which focused on full-term and near-term infant with NEC has been reported. The aim of this study was to evaluate the effect of broad-spectrum antibiotic plus metronidazole in preventing the deterioration of NEC from stage II to III in full-term and near-term infants.A retrospective cohort study based on the propensity score (PS) 1:1 matching was performed among the full-term and near-term infants with NEC (Bell stage ≥II). All infants who received broad-spectrum antibiotics were divided into 2 groups: group with metronidazole treatment (metronidazole was used ≥4 days continuously, 15 mg/kg/day) and group without metronidazole treatment. The depraved rates of stage II NEC between the 2 groups were compared. Meanwhile, the risk factors associated with the deterioration of stage II NEC were analyzed by case-control study in the PS-matched cases.A total of 229 infants met the inclusion criteria. Before PS-matching, we found the deterioration of NEC rate in the group with metronidazole treatment was higher than that in the group without metronidazole treatment (18.1% [28/155] vs 8.1% [6/74]; P = 0.048). After PS-matching, 73 pairs were matched, and the depraved rate of NEC in the group with metronidazole treatment was not lower than that in the group without metronidazole treatment (15.1% vs 8.2%; P = 0.2). Binary logistic regression analysis showed that sepsis after NEC (odds ratio [OR] 3.748, 95% confidence interval [CI] 1.171-11.998, P = 0.03), the need to use transfusion of blood products after diagnosis of NEC (OR 8.003, 95% CI 2.365-27.087, P = 0.00), and the need of longer time for nasogastric suction were risk factors for stage II NEC progressing to

    Introduction Patients with stage III non-small cell lung cancer (NSCLC) and poor performance status (PS) and/or weight loss (WL) do not seem to benefit from standard therapy. Based on the pre-clinical interaction between epidermal growth factor receptor (EGFR) inhibitors and radiation, we designed a trial of induction chemotherapy followed by thoracic radiotherapy (TRT) and concurrent erlotinib. Methods Patients with poor risk unresectable stage III NSCLC received 2 cycles of carboplatin at an AUC of 5 and nab-paclitaxel at 100 mg/m2 on days 1 and 8 every 21 days, followed by erlotinib administered concurrently with TRT. Maintenance was not permitted. Molecular analysis was performed in available specimens. Seventy-two eligible patients were required to test whether the 1-year survival rate was <50% or ≥65% with approximately 90% power at a significance level of 0.10. Results From March 2008 to October 2011, 78patients were enrolled, 3 of which were ineligible. The median age was 68 (range, 39 to 88) and 32% were ≥75 years of age. Patients were evenly distributed between stage IIIA and IIIB and the majority had PS 2. The overall response rate was 67% and the disease control rate was 93%. Treatment was well tolerated. The median PFS and OS were 11 and 17 months, respectively. The overall 12-month OS was 57%, which narrowly missed the pre-specified target for significance. Conclusions Patients with poor risk stage III NSCLC had better than expected outcomes with a regimen of induction carboplatin/nab-paclitaxel followed by TRT and erlotinib. However, as per the statistical design, the 12-month OS was not sufficiently high to warrant further studies. PMID:25384173

    A two-stage oxidation (UV-Na(2)S(2)O(8)/H(2)O(2)-Fe(II,III)) process was applied to mineralize bisphenol A (BPA) at pH(i) (initial pH) 7. We take advantage of the high oxidation potential of sulfate radicals and use persulfate as the 1st-stage oxidant to oxidize BPA to less complex compounds (stoichiometric ratio: [S(2)O(8)(2-)](0)/[BPA](0)=1). Afterwards, the traditional photo-Fenton process was used to mineralize those compounds to CO(2). To the best of our knowledge, this is the first attempt to utilize the two processes in conjunction for the complete degradation of BPA. During the 2nd-stage reaction, other oxidants (H(2)O(2) and Iron alone) were also employed to observe the extent of enhancement of photo-Fenton. Further, qualitative identification of both hydroxyl and sulfate radicals was performed to evaluate their dominance under different conditions. The BPA degradation in this UV/persulfate process formulated a pseudo-first-order kinetic model well, with a rate constant of approximately 0.038 min(-1) (25 degrees C), 0.057 min(-1) (35 degrees C), and 0.087 min(-1) (50 degrees C), respectively. The much lower activation energy (DeltaE = 26 kJ mol(-1)) was further calculated to clarify that the thermal-effect of an illuminated system differs from single heat-assisted systems described in other research. Final total organic carbon (TOC) removal levels of BPA by the use of such two-stage oxidation processes were 25-34%, 25%, and 87-91% for additional Fe(II,III) activation, H(2)O(2) promotion, and Fe(II,III)/H(2)O(2) promotions, respectively.

    This article is aimed to compare the dosimetric differences between volumetric modulated arc therapy (VMAT) and intensity-modulated radiotherapy (IMRT) for Stage I-II nasal natural killer/T-cell lymphoma (NNKTL). Ten patients with Stage I-II NNKTL treated with IMRT were replanned with VMAT (2 arcs). The prescribed dose of the planning target volume (PTV) was 50Gy in 25 fractions. The VMAT plans with the Anisotropic Analytical Algorithm (Version 8.6.15) were based on an Eclipse treatment planning system; the monitor units (MUs) and treatment time (T) were scored to measure the expected treatment efficiency. All the 10 patients under the study were subject to comparisons regarding the quality of target coverage, the efficiency of delivery, and the exposure of normal adjacent organs at risk (OARs). The study shows that VMAT was associated with a better conformal index (CI) and homogeneity index (HI) (both p < 0.05) but slightly higher dose to OARs than IMRT. The MUs with VMAT (650.80 ± 24.59) were fewer than with IMRT (1300.10 ± 57.12) (relative reduction of 49.94%, p = 0.00) when using 2-Gy dose fractions. The treatment time with VMAT (3.20 ± 0.02 minutes) was shorter than with IMRT (7.38 ± 0.18 minutes) (relative reduction of 56.64%, p = 0.00). We found that VMAT and IMRT both provide satisfactory target dosimetric coverage and OARs sparing clinically. Likely to deliver a bit higher dose to OARs, VMAT in comparison with IMRT, is still a better choice for treatment of patients with Stage I-II NNKTL, thanks to better dose distribution, fewer MUs, and shorter delivery time.

    Background: We have developed a new radiosensitization treatment called Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II (KORTUC II). Using KORTUC II, we performed breast-conserving treatment (BCT) without any surgical procedure for elderly patients with breast cancer in stages I/II or patients refusing surgery. Since surgery was not performed, histological confirmation of the primary tumor region following KORTUC II treatment was not possible. Therefore, to precisely evaluate the response to this new therapy, a detailed diagnostic procedure is needed. The goal of this study was to evaluate the therapeutic response to KORTUC II treatment in patients with stage I/II breast cancer using annual breast contrast-enhanced (CE) magnetic resonance imaging (MRI). Methods: Twenty-one patients with stage I/II breast cancer who were elderly and/or refused surgery were enrolled in this study. All patients underwent MRI prior to and at 3 to 6 months after KORTUC II, and then approximately biannually thereafter. Findings from MRI were compared with those from other diagnostic modalities performed during the same time period. Results: KORTUC II was well tolerated, with minimal adverse effects. All of 21 patients showed a clinically complete response (cCR) on CE MRI. The mean period taken to confirm cCR on the breast CE MRI was approximately 14 months. The mean follow-up period for the patients was 61.9 months at the end of October 2014. Conclusions: The therapeutic effect of BCT using KORTUC II without surgery could be evaluated by biannual CE MRI evaluations. Approximately 14 months were required to achieve cCR in response to this therapy. PMID:26703733

    Purpose: To assess the efficacy of radiotherapy (RT) combined with regional hyperthermia (HT) guided by radiofrequency (RF)-output power and intraesophageal temperature and evaluate the potential contribution of HT to clinical outcomes in patients with Stage III non-small-cell lung cancer (NSCLC). Methods and Materials: Thirty-five patients with Stage III NSCLC treated with RT plus regional HT were retrospectively analyzed. Twenty-two of the 35 patients underwent intraesophageal temperature measurements. Patients with subcutaneous fat of 2.5 cm or greater, older age, or other serious complications did not undergo this therapy. The 8-MHz RF-capacitive heating device was applied, and in all patients, both the upper and lower electrodes were 30 cm in diameter, placed on opposite sides of the whole thoracic region, and treatment posture was the prone position. The HT was applied within 15 minutes after RT once or twice a week. Results: All thermal parameters, minimum, maximum, and mean of the four intraesophageal temperature measurements at the end of each session and the proportion of the time during which at least one of the four intraesophageal measurements was 41{sup o}C or higher in the total period of each session of HT, of the intraesophageal temperature significantly correlated with median RF-output power. Median RF-output power ({>=}1,200 W) was a statistically significant prognostic factor for overall, local recurrence-free, and distant metastasis-free survival. Conclusions: The RT combined with regional HT using a higher RF-output power could contribute to better clinical outcomes in patients with Stage III NSCLC. The RF-output power thus may be used as a promising parameter to assess the treatment of deep regional HT if deep heating using this device is performed with the same size electrodes and in the same body posture.

    Purpose: The purpose of this study was to investigate the role of postmastectomy radiation therapy (PMRT) after neoadjuvant chemotherapy (NAC) in clinical stage II-III breast cancer patients with pN0. Methods and Materials: We retrospectively identified 417 clinical stage II-III breast cancer patients who achieved an ypN0 at surgery after receiving NAC between 1998 and 2009. Of these, 151 patients underwent mastectomy after NAC. The effect of PMRT on disease-free survival (DFS), locoregional recurrence-free survival (LRRFS), and overall survival (OS) was evaluated by multivariate analysis including known prognostic factors using the Kaplan-Meier method and compared using the log–rank test and Cox proportional regression analysis. Results: Of the 151 patients who underwent mastectomy, 105 (69.5%) received PMRT and 46 patients (30.5%) did not. At a median follow-up of 59 months, 5 patients (3.3%) developed LRR (8 sites of recurrence) and 14 patients (9.3%) developed distant metastasis. The 5-year DFS, LRRFS, and OS rates were 91.2, 98.1, and 93.3% with PMRT and 83.0%, 92.3%, and 89.9% without PMRT, respectively (all P values not significant). By univariate analysis, only age (≤40 vs >40 years) was significantly associated with decreased DFS (P=.027). By multivariate analysis, age (≤40 vs >40 years) and pathologic T stage (0-is vs 1 vs 2-4) were significant prognostic factors affecting DFS (hazard ratio [HR] 0.353, 95% confidence interval [CI] 0.135-0.928, P=.035; HR 2.223, 95% CI 1.074-4.604, P=.031, respectively). PMRT showed no correlation with a difference in DFS, LRRFS, or OS by multivariate analysis. Conclusions: PMRT might not be necessary for pN0 patients after NAC, regardless of clinical stage. Prospective randomized clinical trial data are needed to assess whether PMRT can be safely omitted in pN0 patients after NAC and mastectomy for clinical stage II-III breast cancer.

    Children with B cell non-Hodgkin's lymphoma who have not relapsed 1 year after diagnosis and treatment are generally cured. We report here the results of treatment in 114 children who all had a minimum follow-up of 20 months. The protocol LMB 0281 from the French Pediatric Oncology Society was used. This nine-drug intensive-pulsed chemotherapy was based on high-dose cyclophosphamide, high-dose methotrexate (HD MTX), and cytosine arabinoside (ara-C) in continuous infusion. CNS prophylaxis was with chemotherapy only. No local irradiation was performed. No debulking surgery was recommended. There were 72 patients with stage III lymphoma and 42 patients with stage IV lymphoma or B cell acute lymphocytic leukemia (B-ALL). Among those 42 patients, seven had CNS involvement alone, 21 had bone marrow alone, and 14 had both; 26 had greater than 25% blast cells in bone marrow, 14 of whom had blast cells in blood. The primary site of involvement was the abdomen in 90 patients, the Waldeyer Ring in nine, and various sites in eight; seven patients presented without tumor. Seventy-seven patients are alive with a median follow-up of 2 years and 8 months. Seven patients died due to initial treatment failure, 11 died from toxicity, and 19 died after relapse. Among the 93 patients without initial CNS involvement, only one isolated relapse in CNS occurred. Survival and disease-free survival rates reached 67% and 64%, respectively, for all patients, 75% and 73% for stage III patients and 54% and 48% for stage IV and B-ALL patients. Bone marrow involvement was not an adverse prognostic factor. Contrary initial CNS involvement indicated a bad prognosis with a disease-free survival rate of 19% compared with 76% without CNS disease. This study showed that CNS prophylaxis and local control of the primary tumor can be achieved by intensive chemotherapy alone, without radiotherapy or debulking surgery. PMID:3525767

    Purpose: To present treatment outcomes of hypofractionated high-dose proton beam therapy for Stage I non-small-cell lung cancer (NSCLC). Methods and Materials: Twenty-one patients with Stage I NSCLC (11 with Stage IA and 10 with Stage IB) underwent hypofractionated high-dose proton beam therapy. At the time of irradiation, patient age ranged from 51 to 85 years (median, 74 years). Nine patients were medically inoperable because of comorbidities, and 12 patients refused surgical resection. Histology was squamous cell carcinoma in 6 patients, adenocarcinoma in 14, and large cell carcinoma in 1. Tumor size ranged from 10 to 42 mm (median, 25 mm) in maximum diameter. Three and 18 patients received proton beam irradiation with total doses of 50 Gy and 60 Gy in 10 fractions, respectively, to primary tumor sites. Results: Of 21 patients, 2 died of cancer and 2 died of pneumonia at a median follow-up period of 25 months. The 2-year overall and cause-specific survival rates were 74% and 86%, respectively. All but one of the irradiated tumors were controlled during the follow-up period. Five patients showed recurrences 6-29 months after treatment, including local progression and new lung lesions outside of the irradiated volume in 1 and 4 patients, respectively. The local progression-free and disease-free rates were 95% and 79% at 2 years, respectively. No therapy-related toxicity of Grade {>=}3 was observed. Conclusions: Hypofractionated high-dose proton beam therapy seems feasible and effective for Stage I NSCLC. Proton beams may contribute to enhanced efficacy and lower toxicity in the treatment of patients with Stage I NSCLC.

    Purpose: To evaluate, in a Phase II trial conducted August 1998 through January 2001, the efficacy of neoadjuvant chemotherapy followed by chemoradiotherapy and definitive surgery in patients with locally advanced non-small-cell lung cancer (LA-NSCLC), Stages IIIA bulky and selected Stage IIIB. Patients and Methods: Staging of LA-NSCLC included computed tomography of cranium, thorax, and abdomen, whole-body positron emission tomography, and video mediastinoscopy. Induction chemotherapy with weekly paclitaxel and carboplatin was followed by hyperfractionated accelerated thoracic radiotherapy (45 Gy) with simultaneous weekly paclitaxel and carboplatin. Four to six weeks after completion of induction therapy, restaging and resection of primary tumor and lymph nodes was intended. Results: A total of 59 consecutive patients were enrolled, 25% with Stage IIIA bulky disease, 65% with Stage IIIB, and 10% with Stage IV (excluded from further analysis). Forty-one patients completed induction therapy; in 52.4% a functional (positron emission tomography) downstaging was proven. Thirty-two patients (59.3%) underwent complete tumor resection, and 5 patients had an exploratory thoracotomy only. Histopathologic downstaging was proven in 59.4% and complete response in 21.9%. Hospital mortality was 5.4%. Median duration of follow-up for living patients was 62.1 months. Overall median survival was 22.6 months, 58.2 months for completely resected patients. During induction chemotherapy, Grade 3/4 granulocytopenia occurred in 8% of patients; the most common Grade 3/4 toxicity of chemoradiation was esophagitis, in 26.4% of patients. Conclusions: Induction paclitaxel/carboplatin with hyperfractionated accelerated chemoradiotherapy followed by complete tumor resection demonstrates high efficacy in LA-NSCLC and offers a promising chance of long-term survival.

    Purpose: We evaluated the efficacy of synchronous three-dimensional (3D) conformal boost to the gross tumor volume (GTV) in concurrent chemoradiotherapy for patients with locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Eligibility included unresectable Stage III NSCLC with no pleural effusion, no supraclavicular nodal metastases, and Eastern Cooperative Oncology Group performance score of 0-1. Forty-nine patients with pathologically proven NSCLC were enrolled. Eighteen patients had Stage IIIA and 31 had Stage IIIB. By using 3D conformal radiotherapy (RT) techniques, a dose of 1.8 Gy was delivered to the planning target volume with a synchronous boost of 0.6 Gy to the GTV, with a total dose of 60 Gy to the GTV and 45 Gy to the planning target volume in 25 fractions during 5 weeks. All patients received weekly chemotherapy consisting of paclitaxel and carboplatin during RT. Results: With a median follow-up of 36.8 months (range, 29.0-45.5 months) for surviving patients, median survival was 28.1 months. One-, 2- and 3-year overall survival rates were 77%, 56.4%, and 43.8%, respectively. Corresponding local progression-free survival rates were 71.2%, 53.7%, and 53.7%. Compliance was 90% for RT and 88% for chemotherapy. Acute esophagitis of Grade 2 or higher occurred in 29 patients. Two patients with T4 lesions died of massive bleeding and hemoptysis during treatment (Grade 5). Overall late toxicity was acceptable. Conclusions: Based on the favorable outcome with acceptable toxicity, the acceleration scheme using 3D conformal GTV boost in this trial is warranted to compare with conventional fractionation in a Phase III trial.

    Summary Background The ACCENT group previously established disease-free survival (DFS) with 2 or 3 years median follow-up to predict 5 year overall survival (5yr OS) in stage II and III colon cancer. ACCENT further proposed (1) a stronger association between DFS and OS in stage III than II, and (2) 6 or 7 years necessary to demonstrate DFS/OS surrogacy in recent trials. The relationship between endpoints in trials with oral fluoropyrimidines, oxaliplatin, and irinotecan is unknown. Methods Associations between the treatment effect hazard ratios (HRs) on 2 and 3yr DFS, and 5 and 6yr OS were examined in 6 phase III trials not included in prior analyses from 1997-2002. Individual data for 12,676 patients were analyzed; two trials each tested oxaliplatin, irinotecan, and oral treatment vs 5-FU/LV. Findings Overall association between 2/3 yr DFS and 5/6 yr OS HRs was modest to poor (simple R2 measures: 0.58 to 0.76, model-based R2: 0.17 to 0.49). In stage III patients, the association increased (model-based R2≥0.79). Observed treatment effects on 2 yr DFS accurately 5/6 yr OS effects overall and in stage III patients. Interpretation In recent trials of cytotoxic chemotherapy, 2 or 3yr DFS HRs are highly predictive of 5 and 6yr OS HRs in stage III but not stage II patients. In all patients the DFS/OS association is stronger for 6yr OS, thus at least 6 year follow-up is recommended to assess OS benefit. These data support DFS as the primary endpoint for stage III colon cancer trials testing cytotoxic agents.

    Current clinical algorithms are unable to precisely predict which colorectal cancer patients would benefit from adjuvant chemotherapy, and there is a need for novel biomarkers to improve the selection of patients. The metastasis-promoting protein S100A4 predicts poor outcome in colorectal cancer, but whether it could be used to guide clinical decision making remains to be resolved. S100A4 expression was analyzed by immunohistochemistry in primary colorectal carcinomas from a consecutively collected, population-representative cohort and a randomized phase III study on adjuvant 5-fluorouracil/levamisole. Sensitivity to treatment with 5-fluorouracil in S100A4 knockdown cells was investigated using 2D and 3D cell culture assays. Strong nuclear expression of S100A4 was detected in 19% and 23% of the tumors in the two study cohorts, respectively. In both cohorts, nuclear immunoreactivity was associated with reduced relapse-free (P < 0.001 and P = 0.010) and overall survival (P = 0.046 and P = 0.006) in univariate analysis. In multivariate analysis, nuclear S100A4 was a predictor of poor relapse-free survival in the consecutive series (P = 0.002; HR 1.9), but not in the randomized study. Sensitivity to treatment with 5-fluorouracil was not affected by S100A4 expression in in vitro cell culture assays, and there was no indication from subgroup analyses in the randomized study that S100A4 expression was associated with increased benefit of adjuvant treatment with 5-fluorouracil/levamisole. The present study confirms that nuclear S100A4 expression is a negative prognostic biomarker in colorectal cancer, but the clinical utility in selection of patients for adjuvant fluoropyrimidine-based chemotherapy is limited.

There are several significant improvements to the Tumor, Nodes, and Metastases (TNM) staging system, including consideration of high-risk factors within the primary T grade, a decrease in the tumor size threshold from 5 cm to 2 cm, improved stratification of patient lymph node status, as well as exclusion of Merkel cell carcinomas from the staging system for squamous cell carcinoma (SCC) and other cutaneous carcinomas. However, some important variables in cutaneous SCC were excluded from consideration. In addition, the AJCC Cancer Staging Manual makes some recommendations that will likely prove difficult to apply in clinical practice, particularly that Clark level, depth of invasion, and presence or absence of perineural invasion should be recorded for each peripheral SCC. In this review, we examine the new recommendations with an emphasis on their utility and practicality. PMID:21469759

    Specific two-stage reversible reaction A + A↔C↔B + B of the decay of species C reactants by two independent transition channels is considered on the basis of the general theory of multistage reactions of isolated pairs of reactants. It is assumed that at the initial instant of time, the reacting system contains only reactants C. The employed general approach has made it possible to consider, in the general case, the inhomogeneous initial distribution of reactants, and avoid application of model concepts of a reaction system structure (i.e., of the structure of reactants and their molecular mobility). Slowing of multistage reaction kinetics as compared to the kinetics of elementary stages is established and physically interpreted. To test approximations (point approximation) used to develop a universal kinetic law, a widely employed specific model of spherical particles with isotropic reactivity diffusing in solution is applied. With this particular model as an example, ultimate kinetics of chemical conversion of reactants is investigated. The question concerning the depths of chemical transformation at which long-term asymptotes are reached is studied. PMID:27083711

    Background Breast cancer has been poorly studied in women with intellectual disability (ID), which makes designing a policy for screening the nearly 70 million women with ID in the world difficult. As no data is available in the literature, we evaluated breast cancer at diagnosis in women with ID. Methods Women with ID were searched retrospectively among all women treated for invasive breast cancer in a single hospital over 18 years. Age at diagnosis was compared among the whole group of women. Tumor size, lymph node involvement, SBR grade, TNM classification, and AJCC stage were compared to controls matched for age and period of diagnosis using conditional logistic regression. Results Among 484 women with invasive breast cancer, 11 had ID. The mean age at diagnosis was 55.6 years in women with ID and 62.4 years in the other women. The mean tumor size in women with ID was 3.53 cm, compared to 1.80 cm in 44 random controls from among the 473 women without ID. Lymph node involvement was observed in 9 of the 11 women with ID compared to 12 of the controls (OR = 11.53, p = 0.002), and metastases were found in 3 of the 11 women with ID compared to 1 of the 44 controls (OR = 12.00, p = 0.031). The AJCC stage was higher in women with ID compared to controls (OR = 3.19, p = 0.010). Conclusions Women with ID presented at an earlier age with tumors of a higher AJCC stage than controls despite no significant differences in tumor grade and histological type. Thus, delayed diagnosis may be responsible for the differences between disabled and non-disabled women. PMID:24593240

    A Mark 25 torpedo power plant modified to operate as a single-stage turbine was investigated to determine the performance with two nozzle designs and a standard first-stage rotor having 0.40-inch blades with a 17O met-air angle. Both nozzles had smaller port cross-sectional areas than those nozzles of similar design, which were previously investigated. The performance of the two nozzles was compared on the basis of blade, rotor, and brake efficiencies as a function of blade-jet speed ratio for pressure ratios of 8, 15 (design), and 20. At pressure ratios of 15 and 20, the blade efficiency obtained with the nozzle having circular passages (K) was higher than that obtained with the nozzle having rectangular passages (J). At a pressure ratio of 8, the efficiencies obtained with the two nozzles were comparable for blade-jet speed ratios of less than 0.260. For blade-jet speed ratios exceeding this value, nozzle K yielded slightly higher efficiencies. The maximum blade efficiency of 0.569 was obtained with nozzle K at a pressure ratio of 8 and a blade-jet speed ratio of 0.295. At design speed and pressure ratio, nozzle K yielded a maximum blade efficiency of 0.534, an increase of 0.031 over that obtained with nozzle J. When the blade efficiencies of the two nozzles were compared with those of four other nozzles previously investigated, the maximum difference for the six nozzles with this rotor was 0.050. From, this comparison, no specific effect of nozzles size or shape on over-all performance was discernible.

    We describe a phase III trial on 200 patients with end stage squamous cell carcinoma of the head and neck. The patients were randomised to one of four treatment arms: cisplatinum alone, methotrexate alone, cisplatinum + 5-FU and cisplatinum + methotrexate. There was no significant difference in the response rates, but the survival of the cisplatinum arm was significantly better than that of the methotrexate arm. The survival of patients receiving cisplatinum as a single agent was longer than that of patients receiving cisplatinum in combination with methotrexate or 5-FU, but not significantly so. Nausea/vomiting and anaemia were significantly more common in the cisplatinum arms than in the methotrexate arm, but the toxicity of combination regimens was not significantly greater than that of cisplatinum used as a single agent.

    Purpose To investigate outcome for patients with follicular lymphoma (FL) stage I-II treated at a population-based referral institution with a median follow-up of 15 years. Overall and cause-specific survival was compared to that of a sex, age and residency matched individuals from normal population. Material and Methods 404 patients with early stage FL treated between 1980 and 2005 were retrospectively analyzed. Two of three patients had stage I disease. Based on clinical characteristics, first line treatments were radiotherapy (RT) (48% of patients), chemotherapy (CT) (16%), combined chemo-and radiotherapy (CRT) (16%) or observation (OBS) (15%). Survival was modeled with Kaplan-Meier methodology. Multivariate analyses were performed with the Cox model. Results Fifteen years overall survival (OS), progression free survival (PFS) and time to next treatment (TNT) were 50% (95% confidence interval [CI]: 45–55), 42% (95% CI: 36–47) and 48% (95% CI, 42–54), respectively. For patients treated with RT 97% achieved a complete remission, and 15 year OS, PFS and TNT were 57% (95% CI, 50–64), 46% (95% CI, 39–54) and 49% (95% CI, 42–57), respectively. Relapse rate after RT and CRT was 49% and 36%, respectively. Only 2% of patients who received RT or CRT relapsed inside the radiation field and 5% had isolated near-field relapse. No statistical differences were found between treatment groups regarding death from cardiovascular disease or incidence of second cancer. Compared to a matched normal population, non-lymphoma cancer mortality was higher among patients given RT, hazard ratio 1.66 (95% CI: 1.14–2.42; P<0.01). Compared to other treatment modalities, patients selected for observation without treatment did not have inferior outcome. Conclusions A differentiated treatment strategy in early stage FL results in long term survival for the majority of patients. OBS is a valid initial choice for selected patients without lymphoma-related symptoms. PMID:26147646

    Purpose: To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non–small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT). Patients and Methods: Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated. Results: A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficient specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR. Conclusions: Our study is the first to show radiosensitive biology of EGFR-mutated tumors in definitive CRT with curative intent. This finding could serve as a credible baseline estimate of EGFR-mutated population in stage III nonsquamous NSCLC.

    Purpose These studies were conducted to determine the relationship between quantitative tumor gene expression and risk of cancer recurrence in patients with stage II or III colon cancer treated with surgery alone or surgery plus fluorouracil (FU) and leucovorin (LV) to develop multigene algorithms to quantify the risk of recurrence as well as the likelihood of differential treatment benefit of FU/LV adjuvant chemotherapy for individual patients. Patients and Methods We performed quantitative reverse transcription polymerase chain reaction (RT-qPCR) on RNA extracted from fixed, paraffin-embedded (FPE) tumor blocks from patients with stage II or III colon cancer who were treated with surgery alone (n = 270 from National Surgical Adjuvant Breast and Bowel Project [NSABP] C-01/C-02 and n = 765 from Cleveland Clinic [CC]) or surgery plus FU/LV (n = 308 from NSABP C-04 and n = 508 from NSABP C-06). Overall, 761 candidate genes were studied in C-01/C-02 and C-04, and a subset of 375 genes was studied in CC/C-06. Results A combined analysis of the four studies identified 48 genes significantly associated with risk of recurrence and 66 genes significantly associated with FU/LV benefit (with four genes in common). Seven recurrence-risk genes, six FU/LV-benefit genes, and five reference genes were selected, and algorithms were developed to identify groups of patients with low, intermediate, and high likelihood of recurrence and benefit from FU/LV. Conclusion RT-qPCR of FPE colon cancer tissue applied to four large independent populations has been used to develop multigene algorithms for estimating recurrence risk and benefit from FU/LV. These algorithms are being independently validated, and their clinical utility is being evaluated in the Quick and Simple and Reliable (QUASAR) study. PMID:20679606

    Purpose: To determine the maximum tolerated dose in concurrent three-dimensional conformal radiotherapy (3D-CRT) with chemotherapy for unresectable Stage III non-small-cell lung cancer (NSCLC). Patients and Methods: Eligible patients with unresectable Stage III NSCLC, age {>=}20 years, performance status 0-1, percent of volume of normal lung receiving 20 GY or more (V{sub 20}) {<=}30% received three to four cycles of cisplatin (80 mg/m{sup 2} Day 1) and vinorelbine (20 mg/m{sup 2} Days 1 and 8) repeated every 4 weeks. The doses of 3D-CRT were 66 Gy, 72 Gy, and 78 Gy at dose levels 1 to 3, respectively. Results: Of the 17, 16, and 24 patients assessed for eligibility, 13 (76%), 12 (75%), and 6 (25%) were enrolled at dose levels 1 to 3, respectively. The main reasons for exclusion were V{sub 20} >30% (n = 10) and overdose to the esophagus (n = 8) and brachial plexus (n = 2). There were 26 men and 5 women, with a median age of 60 years (range, 41-75). The full planned dose of radiotherapy could be administered to all the patients. Grade 3-4 neutropenia and febrile neutropenia were noted in 24 (77%) and 5 (16%) of the 31 patients, respectively. Grade 4 infection, Grade 3 esophagitis, and Grade 3 pulmonary toxicity were noted in 1 patient, 2 patients, and 1 patient, respectively. The dose-limiting toxicity was noted in 17% of the patients at each dose level. The median survival and 3-year and 4-year survival rates were 41.9 months, 72.3%, and 49.2%, respectively. Conclusions: 72 Gy was the maximum dose that could be achieved in most patients, given the predetermined normal tissue constraints.

    This phase II trial tested the rate of pathologic complete response (pCR) achieved by women with stage II–III human epidermal growth factor receptor 2-negative (HER2-negative) breast cancer (BC) treated with neo-adjuvant nanoparticle albumin-bound paclitaxel (nab-P), carboplatin and bevacizumab. The rate of pCR was 18%, all pCRs were observed in patients with triple negative BC. Background We hypothesized that adding bevacizumab to neoadjuvant chemotherapy (NCT) with nab-P and carboplatin would increase the rates of pCR in BC patients and that early changes in tumor vascularity imaged by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) would predict pCR. Methods Thirty-three women with clinical stage II or III HER2-negative BC received nab-P 100 mg/m2 and carboplatin area under the curve = 2 on days 1, 8, and 15 in combination with bevacizumab 10 mg/kg on days 1 and 15 administered every 28 days. Results Six patients (18%) achieved pCR, all pCRs occurred in triple-negative BC (TNBC) (pCR = 50% for TNBC). At the end of cycle 2, the changes in relative angiogenic volume were significantly different between responders and non-responders (P = .001). The major toxicity of this NCT was myelosuppression. Conclusion NCT with weekly nab-P, carboplatin, and biweekly bevacizumab resulted in a pCR rate that was neither superior to the historical data with anthracycline- or taxane-containing NCT nor to carboplatin and taxane combinations in patients with HER2-negative BC. In patients with TNBC, the observed pCR rate was 50%. The early changes in the relative angiogenic volume imaged by DCE-MRI could predict pCR. PMID:24703985

    Purpose: To determine the accuracy of four-dimensional computed tomography (4D-CT) scanning techniques in institutions participating in a Phase III trial of surgery vs. stereotactic radiotherapy (SBRT) for lung cancer. Methods and Materials: All 9 centers performed a 4D-CT scan of a motion phantom (Quasar, Modus Medical Devices) in accordance with their in-house imaging protocol for SBRT. A cylindrical cedar wood insert with plastic spheres of 15 mm (o15) and 30 mm (o30) diameter was moved in a cosine-based pattern, with an extended period in the exhale position to mimic the actual breathing motion. A range of motion of R = 15 and R = 25 mm and breathing period of T = 3 and T = 6 s were used. Positional and volumetric imaging accuracy was analyzed using Pinnacle version 8.1x at various breathing phases, including the mid-ventilation phase and maximal intensity projections of the spheres. Results: Imaging using eight CT scanners (Philips, Siemens, GE) and one positron emission tomography-CT scanner (Institution 3, Siemens) was investigated. The imaging protocols varied widely among the institutions. No strong correlation was found between the specific scan protocol parameters and the observed results. Deviations in the maximal intensity projection volumes averaged 1.9% (starting phase of the breathing cycle [o]15, R = 15), 12.3% (o15, R = 25), and -0.9% (o30, R = 15). The end-expiration volume deviations (13.4%, o15 and 2.5%, o30), were, on average, smaller than the end-inspiration deviations (20.7%, o15 and 4.5%, o30), which, in turn, were smaller than the mid-ventilation deviations (32.6%, o15 and 8.0%, o30). A slightly larger variation in the mid-ventilation origin position was observed (mean, -0.2 mm; range, -3.6-4.2) than in the maximal intensity projection origin position (mean, -0.1 mm; range, -2.5-2.5). The range of motion was generally underestimated (mean, -1.5 mm; range, -5.5-1). Conclusions: Notable differences were seen in the 4D-CT imaging protocols

    Aim This study was designed to evaluate the efficacy and toxicities of concomitant boost intensity-modulated radiation therapy (IMRT) along with capecitabine and oxaliplatin, followed by a cycle of Xelox, in neoadjuvant course for locally advanced rectal cancer. Materials and methods Patients with histologically confirmed, newly diagnosed, locally advanced rectal adenocarcinoma (cT3-T4 and/or cN+) located within 12 cm of the anal verge were included in this study. Patients received IMRT to the pelvis of 50 Gy and a concomitant boost of 5 Gy to the primary tumor in 25 fractions, and concurrent with oxaliplatin (50 mg/m2 d1 weekly) and capecitabine (625 mg/m2 bid d1–5 weekly). One cycle of Xelox (oxaliplatin 130 mg/m2 on d1 and capecitabine 1000 mg/m2 twice daily d1–14) was given two weeks after the completion of chemoradiation, and radical surgery was scheduled eight weeks after chemoradiation. Tumor response was evaluated by tumor regression grade (TRG) system and acute toxicities were evaluated by NCI-CTC 3.0 criteria. Survival curves were estimated using the Kaplan-Meier method and compared with Log-rank test. Results A total of 78 patients were included between March 2009 and May 2011 (median age 54 years; 62 male). Seventy-six patients underwent surgical resection. Twenty-eight patients underwent sphincter-sparing lower anterior resection and 18 patients (23.7%) were evaluated as pathological complete response (pCR). The incidences of grade 3 hematologic toxicity, diarrhea, and radiation dermatitis were 3.8%, 10.3%, and 17.9%, respectively. The three-year LR (local recurrence), DFS (disease-free survival) and OS (overall survival) rates were 14.6%, 63.8% and 77.4%, respectively. Initial clinical T stage and tumor regression were independent prognostic factors to DFS. Conclusion An intensified regimen of concomitant boost radiotherapy plus concurrent capecitabine and oxaliplatin, followed by one cycle of Xelox, can be safely administered in patients

    PubMed

    Mirimanoff, René-Olivier

    2015-12-01

    For decades, surgery was considered to be the only standard therapy for early-stage non-small cell lung cancer (NSCLC). However stereotactic ablative body radiotherapy (SABR) has been used in a growing number of patients and institutions since the early 2000's. Initially this technique was intended mainly for patients who were deemed to be medically inoperable due to co-morbidities or who refused surgery, but more recently it has been applied to operable patients as well. Strict criteria for treatment planning, the use of high-technology equipment and the appropriate selection of dose based on tumor size and location are of paramount importance for a proper application of SABR. Under these conditions, SABR offers high control rates with a moderate risk of severe toxicity, quite comparable to those of modern surgery. This article reviews the basic principles of SABR, its practical aspects, the definition of biologically equivalent doses, the results in terms of tumor control, survival and toxicity and an attempt will be made to compare the results of SABR with those of surgery.

    A 36-yr-old, gravida 5 para 4 woman presented with uterine bleeding and was discovered to have a 3.7-cm uterine mass with multiple, bilateral, lung metastases. Six months earlier, the patient was diagnosed with a partial hydatidiform mole that demonstrated a rare chromosomal karyotype 68, XX[12]. The patient's serum β-human chorionic gonadotropin was elevated from baseline to 12,039 mIU/mL before the treatment. A total hysterectomy was performed and revealed a markedly hemorrhagic, extensively necrotic choriocarcinoma. The tumor mass invaded to a depth of 1/3 of the uterine wall thickness. Cytogenetic analysis of the choriocarcinoma revealed the same 68, XX karyotype, as observed in the antecedent partial hydatidiform mole. A clinical diagnosis of advanced stage invasive choriocarcinoma was rendered, with a risk factor score of 5. Following the development of chemoresistance to a single-agent (methotrexate) regimen, the patient subsequently received 5 cycles of chemotherapy (EMA-CO), without any major complication. She is currently >5 yr posttreatment and is asymptomatic. Her most recent imaging studies, including scans of chest and brain, show no evidence of disease, and her serum β-human chorionic gonadotropin level has remained consistently below detectable levels.

    Iron (Fe) is often encountered in wastewaters. This study investigated the effects of iron on the single-stage deammonification process treating reject water from sludge dewatering. When Fe(2+) and Fe(3+) concentrations in the influent were below 1.3mg/L and 0.4 mg/L, Fe(2+) incorporation was found to be linearly correlated with NH(4)(+)-N removal. However, the excess Fe(2+) and Fe(3+) drastically deteriorated the deammonification performance. Both of the reactor performance and Fluorescence In Situ Hybridization results suggested higher sensitivity of autotrophic bacteria to iron than heterotrophs, the sequence of which was assessed to anammox bacteria>aerobic ammonium oxidizers>hetetrophic denitrifiers. With the excess existence of iron, extracellular substances were largely released by bacterial cells, which were the likely sites for iron uptake by scanning electron microscope-energy dispersive X-ray analysis. The information provided here would be useful to facilitate the application of deammonification process in the treatment of wastewater including metal iron. PMID:22483570

    The prediction of cancer staging in prostate cancer is a process for estimating the likelihood that the cancer has spread before treatment is given to the patient. Although important for determining the most suitable treatment and optimal management strategy for patients, staging continues to present significant challenges to clinicians. Clinical test results such as the pre-treatment Prostate-Specific Antigen (PSA) level, the biopsy most common tumor pattern (Primary Gleason pattern) and the second most common tumor pattern (Secondary Gleason pattern) in tissue biopsies, and the clinical T stage can be used by clinicians to predict the pathological stage of cancer. However, not every patient will return abnormal results in all tests. This significantly influences the capacity to effectively predict the stage of prostate cancer. Herein we have developed a neuro-fuzzy computational intelligence model for classifying and predicting the likelihood of a patient having Organ-Confined Disease (OCD) or Extra-Prostatic Disease (ED) using a prostate cancer patient dataset obtained from The Cancer Genome Atlas (TCGA) Research Network. The system input consisted of the following variables: Primary and Secondary Gleason biopsy patterns, PSA levels, age at diagnosis, and clinical T stage. The performance of the neuro-fuzzy system was compared to other computational intelligence based approaches, namely the Artificial Neural Network, Fuzzy C-Means, Support Vector Machine, the Naive Bayes classifiers, and also the AJCC pTNM Staging Nomogram which is commonly used by clinicians. A comparison of the optimal Receiver Operating Characteristic (ROC) points that were identified using these approaches, revealed that the neuro-fuzzy system, at its optimal point, returns the largest Area Under the ROC Curve (AUC), with a low number of false positives (FPR = 0.274, TPR = 0.789, AUC = 0.812). The proposed approach is also an improvement over the AJCC pTNM Staging Nomogram (FPR = 0.032, TPR

    The prediction of cancer staging in prostate cancer is a process for estimating the likelihood that the cancer has spread before treatment is given to the patient. Although important for determining the most suitable treatment and optimal management strategy for patients, staging continues to present significant challenges to clinicians. Clinical test results such as the pre-treatment Prostate-Specific Antigen (PSA) level, the biopsy most common tumor pattern (Primary Gleason pattern) and the second most common tumor pattern (Secondary Gleason pattern) in tissue biopsies, and the clinical T stage can be used by clinicians to predict the pathological stage of cancer. However, not every patient will return abnormal results in all tests. This significantly influences the capacity to effectively predict the stage of prostate cancer. Herein we have developed a neuro-fuzzy computational intelligence model for classifying and predicting the likelihood of a patient having Organ-Confined Disease (OCD) or Extra-Prostatic Disease (ED) using a prostate cancer patient dataset obtained from The Cancer Genome Atlas (TCGA) Research Network. The system input consisted of the following variables: Primary and Secondary Gleason biopsy patterns, PSA levels, age at diagnosis, and clinical T stage. The performance of the neuro-fuzzy system was compared to other computational intelligence based approaches, namely the Artificial Neural Network, Fuzzy C-Means, Support Vector Machine, the Naive Bayes classifiers, and also the AJCC pTNM Staging Nomogram which is commonly used by clinicians. A comparison of the optimal Receiver Operating Characteristic (ROC) points that were identified using these approaches, revealed that the neuro-fuzzy system, at its optimal point, returns the largest Area Under the ROC Curve (AUC), with a low number of false positives (FPR = 0.274, TPR = 0.789, AUC = 0.812). The proposed approach is also an improvement over the AJCC pTNM Staging Nomogram (FPR = 0.032, TPR

    Thirty-three patients with advanced-stage ovarian adenocarcinomas, with no prior chemotherapy, were treated with weekly cisplatin (DDP) for four courses followed by five monthly courses of one of two randomly assigned multidrug combinations. These combinations were high-dose methotrexate-leucovorin plus cyclophosphamide (MECY) or cyclophosphamide, hexamethylmelamine, doxorubicin, and DDP (CHAD). Patients with no clinically measurable disease after 6 months of therapy were evaluated by laparoscopy. In the absence of disease progression at the time of the laparoscopy the study design called for a repeat cycle of four weekly DDP courses and another five monthly courses of the assigned multidrug combination. All patients with no evidence of disease after 1 year of treatment had a second-look laparoscopy which, if negative, was followed by a second-look laparotomy. This report includes all of the consecutively entered patients observed for a minimum of 1 year or to death. DDP-MECY and DDP-CHAD were similarly active for overall response rates and complete response rates according to laparoscopic criteria. However, DDP-MECY had a statistically significantly lower relapse rate (P less than 0.02) and a statistically significantly higher negative second-look laparotomy rate than did DDP-CHAD. Using all entered patients, with no exclusions from analysis, eight of 17 patients (47%) treated with DDP-MECY had negative second-looks after 1 year of treatment. This compares with one of 16 (6%) negative second-looks in patients treated with DDP-CHAD (P less than 0.02). The high negative second-look rate with DDP-MECY is exciting. Positive cytologic washings at the 6-month laparoscopic evaluation were highly predictive that residual disease would be found at the 1-year second-look surgery. Only one patient with positive peritoneal cytology after 6 months of treatment was found to have a negative second-look after 1 year of therapy. PMID:6439408

    Purpose: Neoadjuvant chemotherapy (NAC) generally induces significant changes in the pathologic extent of disease. This potential down-staging challenges the standard indications of adjuvant radiation therapy. We assessed the utility of lymph node irradiation (LNI) in breast cancer (BC) patients with pathologic N0 status (pN0) after NAC and breast-conserving surgery (BCS). Methods and Materials: Among 1,054 BC patients treated with NAC in our institution between 1990 and 2004, 248 patients with clinical N0 or N1 to N2 lymph node status at diagnosis had pN0 status after NAC and BCS. Cox regression analysis was used to identify factors influencing locoregional recurrence-free survival (LRR-FS), disease-free survival (DFS), and overall survival (OS). Results: All 248 patients underwent breast irradiation, and 158 patients (63.7%) also received LNI. With a median follow-up of 88 months, the 5-year LRR-FS and OS rates were respectively 89.4% and 88.7% with LNI and 86.2% and 92% without LNI (no significant difference). Survival was poorer among patients who did not have a pathologic complete primary tumor response (hazard ratio, 3.05; 95% confidence interval, 1.17-7.99) and in patients with N1 to N2 clinical status at diagnosis (hazard ratio = 2.24; 95% confidence interval, 1.15-4.36). LNI did not significantly affect survival. Conclusions: Relative to combined breast and local lymph node irradiation, isolated breast irradiation does not appear to be associated with a higher risk of locoregional relapse or death among cN0 to cN2 breast cancer patients with pN0 status after NAC. These results need to be confirmed in a prospective study.

    Purpose This study was designed to evaluate the dose coverage of axillary areas during whole breast irradiation with simplified intensity modulated radiation therapy (s-IMRT) and field-in-field IMRT (for-IMRT) in early stage breast cancer patients. Methods Sixty-one consecutive patients with breast-conserving surgery and sentinel lymph node biopsy were collected. Two plans were created for each patient: the s-IMRT and for-IMRT plan. Dosimetric parameters of axillary areas were compared. Results The average of mean doses delivered to the axillary level I areas in s-IMRT and for-IMRT plan were 27.7Gy and 29.1Gy (p = 0.011), respectively. The average of V47.5Gy, V45Gy and V40Gy (percent volume receiving≥ 47.5Gy, 45Gy and 40Gy) of the axillary level I in s-IMRT plan was significantly lower than that in for-IMRT plan (p < 0.001). For for-IMRT plans, patients with upper tangential border to humeral head ≤2cm, breast separation >19.3cm and body width >31.9cm had significantly higher mean dose in axillary level I area (p = 0.002, 0.007, 0.001, respectively). Conclusion Compared with for-IMRT plan, the s-IMRT plan delivered lower dose to axillary level I area. For centers using s-IMRT technique, caution should be exercised when selecting to omit axillary lymph node dissection for patients with breast conserving surgery and limited positive SLNs.

    Background TomoBreast is a unicenter, non-blinded randomized trial comparing conventional radiotherapy (CR) vs. hypofractionated Tomotherapy (TT) for post-operative treatment of breast cancer. The purpose of the trial is to compare whether TT can reduce heart and pulmonary toxicity. We evaluate early toxicities. Methods The trial started inclusion in May 2007 and reached its recruitment in August 2011. Women with stage T1-3N0M0 or T1-2N1M0 breast cancer completely resected by tumorectomy (BCS) or by mastectomy (MA) who consented to participate were randomized, according to a prescribed computer-generated randomization schedule, between control arm of CR 25x2 Gy/5 weeks by tangential fields on breast/chest wall, plus supraclavicular-axillary field if node-positive, and sequential boost 8x2 Gy/2 weeks if BCS (cumulative dose 66 Gy/7 weeks), versus experimental TT arm of 15x2.8 Gy/3 weeks, including nodal areas if node-positive and simultaneous integrated boost of 0.6 Gy if BCS (cumulative dose 51 Gy/3 weeks). Outcomes evaluated were the pulmonary and heart function. Comparison of proportions used one-sided Fisher's exact test. Results By May 2010, 70 patients were randomized and had more than 1 year of follow-up. Out of 69 evaluable cases, 32 were assigned to CR (21 BCS, 11 MA), 37 to TT (20 BCS, 17 MA). Skin toxicity of grade ≥1 at 2 years was 60% in CR, vs. 30% in TT arm. Heart function showed no significant difference for left ventricular ejection fraction at 2 years, CR 4.8% vs. TT 4.6%. Pulmonary function tests at 2 years showed grade ≥1 decline of FEV1 in 21% of CR, vs. 15% of TT and decline of DLco in 29% of CR, vs. 7% of TT (P = 0.05). Conclusions There were no unexpected severe toxicities. Short course radiotherapy of the breast with simultaneous integrated boost over 3 weeks proved feasible without excess toxicities. Pulmonary tests showed a slight trend in favor of Tomotherapy, which will need confirmation with longer

    Purpose The phase III North American Intergroup E2496 Trial (Combination Chemotherapy With or Without Radiation Therapy in Treating Patients With Hodgkin's Lymphoma) compared doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with mechlorethamine, doxorubicin, vincristine, bleomycin, vinblastine, etoposide, and prednisone (Stanford V). We report results of a planned subgroup analysis in patients with stage I or II bulky mediastinal Hodgkin lymphoma (HL). Patients and Methods Patients were randomly assigned to six to eight cycles of ABVD every 28 days or Stanford V once per week for 12 weeks. Two to 3 weeks after completion of chemotherapy, all patients received 36 Gy of modified involved field radiotherapy (IFRT) to the mediastinum, hila, and supraclavicular regions. Patients on the Stanford V arm received IFRT to additional sites ≥ 5 cm at diagnosis. Primary end points were failure-free survival (FFS) and overall survival (OS). Results Of 794 eligible patients, 264 had stage I or II bulky disease, 135 received ABVD, and 129 received Stanford V. Patient characteristics were matched. The overall response rate was 83% with ABVD and 88% with Stanford V. At a median follow-up of 6.5 years, the study excluded a difference of more than 21% in 5-year FFS and more than 16% in 5-year OS between ABVD and Stanford V (5-year FFS: 85% v 79%; HR, 0.68; 95% CI, 0.37 to 1.25; P = .22; 5-year OS: 96% v 92%; HR, 0.49; 95% CI, 0.16 to 1.47; P = .19). In-field relapses occurred in < 10% of the patients in each arm. Conclusion For patients with stage I or II bulky mediastinal HL, no substantial statistically significant differences were detected between the two regimens, although power was limited. To the best of our knowledge, this is the first prospective trial reporting outcomes specific to this subgroup, and it sets a benchmark for comparison of ongoing and future studies. PMID:25897153

  16. Classification, imaging, biopsy and staging of osteosarcoma.

    Osteosarcoma is the most common primary osseous malignancy excluding malignant neoplasms of marrow origin (myeloma, lymphoma and leukemia) and accounts for approximately 20% of bone cancers. It predominantly affects patients younger than 20 years and mainly occurs in the long bones of the extremities, the most common being the metaphyseal area around the knee. These are classified as primary (central or surface) and secondary osteosarcomas arising in preexisting conditions. The conventional plain radiograph is the best for probable diagnosis as it describes features like sun burst appearance, Codman's triangle, new bone formation in soft tissues along with permeative pattern of destruction of the bone and other characteristics for specific subtypes of osteosarcomas. X-ray chest can detect metastasis in the lungs, but computerized tomography (CT) scan of the thorax is more helpful. Magnetic resonance imaging (MRI) of the lesion delineates its extent into the soft tissues, the medullary canal, the joint, skip lesions and the proximity of the tumor to the neurovascular structures. Tc99 bone scan detects the osseous metastases. Positron Emission Tomography (PET) is used for metastatic workup and/or local recurrence after resection. The role of biochemical markers like alkaline phosphatase and lactate dehydrogenase is pertinent for prognosis and treatment response. The biopsy confirms the diagnosis and reveals the grade of the tumor. Enneking system for staging malignant musculoskeletal tumors and American Joint Committee on Cancer (AJCC) staging systems are most commonly used for extremity sarcomas. PMID:24932027

    To compare the pathological features and long-term survival of bladder cancer (BCa) in young patients with elderly counterparts. Using the U.S. National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) population-based data, we identified 93115 patients with non-metastatic bladder cancer diagnosed between 1988 and 2003. Patients were categorized into young (50 years and under) and elderly groups (over 50 years of age). The overall and five-year bladder cancer specific survival (BCSS) data were obtained using Kaplan-Meier plots. Multivariable Cox regression models were built for the analysis of long-term survival outcomes and risk factors. There were significant differences between the two groups in primary site, pathologic grading, histologic type, AJCC stage (p<0.001). The overall and 5-year cancer specific survival rates were 88.1% and 90.8% in young group, 64.8% and 81.3% in elderly group, which had significant difference in both univariate and multivariate analysis (p<0.001). Further analysis showed this significant difference existed across all the AJCC stage patients. The study findings show different patterns in the prognostic value of age for determining BCSS, depending on the tumor stages. Compared with elderly patients, young patients with bladder cancer surgery appear to have unique characteristics and a higher overall and cancer specific survival rate. PMID:26269768

    Purpose: For locoregionally advanced inoperable non-small-cell lung cancer (NSCLC), concurrent chemoradiotherapy has become a standard therapy. We conducted a Phase II trial to examine the efficacy and toxicity of adding gemcitabine and vinorelbine induction chemotherapy to concurrent chemoradiotherapy with oral etoposide and cisplatin. Methods and Materials: Eligibility included inoperable clinical Stage III NSCLC without pleural effusion, ECOG performance status 0-1, and weight loss {<=}5%. Induction chemotherapy consisted of three cycles of gemcitabine 1,000 mg/m{sup 2} and vinorelbine 30 mg/m{sup 2}, each given i.v. on Days 1 and 8, every 3 weeks. During once-daily thoracic radiotherapy (1.8 Gy/day, total 63 Gy), two cycles of oral etoposide (100 mg on Days 1-5 and 8-12) plus cisplatin (50 mg/m{sup 2} on Days 1 and 8) were given concurrently 4 weeks apart. Results: Between April 2002 and November 2003, 42 patients were enrolled and 40 were included in response and toxicity evaluation. The median age was 59 years and 13 patients had IIIA and 27 had IIIB; 24 had squamous ca, 12 had adenocarcinoma, and 4 had others. Objective tumor responses were obtained in 29 patients (72.5%), including 18 (45.0%) after induction chemotherapy. After a median follow-up of 23.8 months, the median survival time and progression-free survival was 23.2 months and 10.9 months, respectively, with 2-year survival rate of 43.9%. For the patients with supraclavicular nodal involvement, the median survival time was 11.8 months with 2-year survival rate of 16.7%, whereas the corresponding figures were 27.8 months and 52.0%, respectively, for those without supraclavicular nodal involvement. Toxicity of induction chemotherapy was mild and well tolerated. However, concurrent chemoradiotherapy was associated with G3/4 hematologic toxicity in 75.7%, G3 esophagitis in 24.2%, and two treatment-related deaths. There were nonlife-threatening late toxicities in additional 6 patients. Conclusions

    Purpose Accurate assessments of recurrence risk and absolute treatment benefit are needed to inform colon cancer adjuvant therapy. The 12-gene Recurrence Score assay has been validated in patients with stage II colon cancer from the Cancer and Leukemia Group B 9581 and Quick and Simple and Reliable (QUASAR) trials. We conducted an independent, prospectively designed clinical validation study of Recurrence Score, with prespecified end points and analysis plan, in archival specimens from patients with stage II and III colon cancer randomly assigned to fluorouracil (FU) or FU plus oxaliplatin in National Surgical Adjuvant Breast and Bowel Project C-07. Methods Recurrence Score was assessed in 892 fixed, paraffin-embedded tumor specimens (randomly selected 50% of patients with tissue). Data were analyzed by Cox regression adjusting for stage and treatment. Results Continuous Recurrence Score predicted recurrence (hazard ratio for a 25-unit increase in score, 1.96; 95% CI, 1.50 to 2.55; P < .001), as well as disease-free and overall survival (both P < .001). Recurrence Score predicted recurrence risk (P = .001) after adjustment for stage, mismatch repair, nodes examined, grade, and treatment. Recurrence Score did not have significant interaction with stage (P = .90) or age (P = .76). Relative benefit of oxaliplatin was similar across the range of Recurrence Score (interaction P = .48); accordingly, absolute benefit of oxaliplatin increased with higher scores, most notably in patients with stage II and IIIA/B disease. Conclusion The 12-gene Recurrence Score predicts recurrence risk in stage II and stage III colon cancer and provides additional information beyond conventional clinical and pathologic factors. Incorporating Recurrence Score into the clinical context may better inform adjuvant therapy decisions in stage III as well as stage II colon cancer. PMID:24220557

    Purpose: Our purpose was to investigate the tolerability of accelerated, twice-daily, high-dose radiotherapy. The secondary endpoints were survival and locoregional tumor control. Methods and Materials: Thirty consecutive patients with histologically/cytologically proven non-small-cell lung cancer were enrolled. Tumor Stage I, II, IIIA, and IIIB was found in 7, 3, 12, and 8 patients, respectively. We applied a median of 84.6 Gy (range, 75.6-90.0 Gy) to the primary tumors, 63.0 Gy (range, 59.4-72.0 Gy) to lymph nodes, and 45 Gy to nodes electively (within a region of about 6 cm cranial to macroscopically involved sites). Fractional doses of 1.8 Gy twice daily, with an interval of 11 hours, were given, resulting in a median treatment time of 35 days. In the majority of patients the conformal target-splitting technique was used. In 19 patients (63%) two cycles of induction chemotherapy were given. The median follow-up time of survivors is 72 months (range, 62-74 months). Results: We found Grade 1, 2 and 3 acute esophageal toxicity in 11 patients (37%), 2 patients (7%), and 2 patients (7%), respectively. Grade 2 acute pneumonitis was seen in 2 patients (7%). No late toxicity greater than Grade 1 was observed. The actual overall survival rates at 2 and 5 years are 63% and 23%, respectively; the median overall survival, 27.7 months. In 9 patients a local failure occurred, 7 of them presenting initially with an atelectasis without availability of 18-fluorodeoxyglucose-positron emission tomography staging at that time. In 4 patients recurrence occurred regionally. Conclusions: This Phase I/II trial with long-term follow-up shows low toxicity with promising results for survival and locoregional tumor control.

    Purpose: To examine the effect of internal mammary node irradiation (IMNI) on disease-free survival (DFS) and overall survival (OS) in breast cancer patients treated with modified radical mastectomy and postoperative radiation therapy. Methods and Materials: Between 1994 and 2002, 396 patients with stage II-III breast cancer were treated with postmastectomy radiation therapy with (n=197) or without (n=199) IMNI. Patients who received neoadjuvant chemotherapy were excluded. IMNI was administered at the clinical discretion of the treating physician. Median RT dose was 50.4 Gy (range, 45.0-59.4 Gy) in 28 fractions, with inclusion of the supraclavicular fossa in 96% of patients. Adjuvant chemotherapy was administered to 99.7% of the patients and endocrine therapy to 53%. Results: The median follow-up was 149 months (range, 124-202). IMNI patients had more advanced nodal stage and non-high grade tumors than those without IMNI (P<.001). Otherwise, disease and treatment characteristics were well balanced. The 10-year DFS with and without IMNI was 65% and 57%, respectively (P=.05). Multivariate analysis demonstrated that IMNI was an independent, positive predictor of DFS (hazard ratio [HR], 0.70; P=.02). Benefits of IMNI in DFS were seen most apparently in N2 patients (HR, 0.44; 95% confidence interval [CI], 0.26-0.74) and inner/central tumors (HR, 0.55; 95% CI, 0.34-0.90). The 10-year OS with and without IMNI was 72% and 66%, respectively (P=.62). The 10-year DFS and OS were 61%, and 69%, respectively. Conclusions: Internal mammary node irradiation significantly improved DFS in postmastectomy breast cancer patients. Pending long-term results from randomized trials, treatment of internal mammary nodes should be considered in postmastectomy radiation therapy.

    Purpose To evaluate the prognostic impact of the lymph node ratio (LNR) in ypStage III rectal cancer patients who were treated with neoadjuvant chemoradiotherapy (NCRT). Materials and Methods We retrospectively reviewed the data of 638 consecutive patients who underwent NCRT followed by total mesorectal excision, and postoperative adjuvant chemotherapy for rectal cancer from 2004 to 2011. Of these, 125 patients were positive for lymph node (LN) metastasis and were analyzed in this study. Results The median numbers of examined and metastatic LNs were 17 and 2, respectively, and the median LNR was 0.143 (range, 0.02–1). Median follow-up time was 55 months. In multivariate analyses, LNR was an independent prognostic factor for overall survival (OS) (hazard ratio [HR] 2.17, p = 0.041), disease-free survival (DFS) (HR 2.28, p = 0.005), and distant metastasis-free survival (DMFS) (HR 2.30, p = 0.010). When ypN1 patients were divided into low (low LNR ypN1 group) and high LNR (high LNR ypN1 group) according to a cut-off value of 0.152, the high LNR ypN1 group had poorer OS (p = 0.043) and DFS (p = 0.056) compared with the low LNR ypN1 group. And there were no differences between the high LNR ypN1 group and the ypN2 group in terms of the OS (p = 0.703) and DFS (p = 0.831). Conclusions For ypN-positive rectal cancer patients, the LNR was a more effective prognostic marker than the ypN stage, circumferential resection margin, or tumor regression grade after NCRT, and could be used to discern the high-risk group among ypN1 patients.

    Purpose Population pharmacokinetics (PK) of sepantronium bromide (YM155) was characterized in patients with non-small cell lung cancer, hormone refractory prostate cancer, or unresectable stage III or IV melanoma and enrolled in one of three phase 2 studies conducted in Europe or the U.S. Method Sepantronium was administered as a continuous intravenous infusion (CIVI) at 4.8 mg/m(2)/day over 7 days every 21 days. Population PK analysis was performed using a linear one-compartment model involving total body clearance (CL) and volume of distribution with an inter-individual random effect on CL and a proportional residual errors to describe 578 plasma sepantronium concentrations obtained from a total of 96 patients by NONMEM Version VI. The first-order conditional estimation method with interaction was applied. Results The one-compartment model with one random effect on CL and two different proportional error models provided an adequate description of the data. Creatinine clearance (CLCR), cancer type, and alanine aminotransferase (ALT) were recognized as significant covariates of CL. CLCR was the most influential covariate on sepantronium exposure and predicted to contribute to a 25 % decrease in CL for patients with moderately impaired renal function (CLCR = 40 mL/min) compared to patients with normal CLCR. Cancer type and ALT had a smaller but nonetheless significant contribution. Other patient characteristics such as age, gender, and race were not considered as significant covariates of CL. Conclusions The results provide the important information for optimizing the therapeutic efficacy and minimizing the toxicity for sepantronium in cancer therapy. PMID:22892872

    Purpose: To determine in a Phase I study the maximum tolerated dose of weekly gemcitabine concurrent with radiotherapy in locally advanced non-small-cell lung cancer (NSCLC), as well as the relationship between the volume of the esophagus irradiated and severe esophagitis. Methods and Materials: Twenty-one patients with Stage III NSCLC received gemcitabine initially at 150 mg/m{sup 2}/wk over 7 weeks concurrently with chest radiotherapy to 63 Gy in 34 fractions. The first 9 patients underwent treatment with two-dimensional (2D) radiotherapy; the remaining 12 patients, with three-dimensional conformal radiotherapy (3D-CRT) and target volume reduced to clinically apparent disease. Consolidation was 4 cycles of gemcitabine at 1000 mg/m{sup 2}/wk and cisplatin 60 mg/m{sup 2}. Results: In the 2D group, the dose-limiting toxicity, Grade 3 esophagitis, occurred in 3 of 6 patients in the 150-mg/m{sup 2}/wk cohort and 2 of 3 patients in the 125-mg/m{sup 2}/wk cohort. No cases of Grade 3 esophagitis occurred at these doses in the 3D group. At gemcitabine 190 mg/m{sup 2}/wk, 2 of 6 patients in the 3D cohort had Grade 3 esophagitis. The mean percentages of esophagus irradiated to 60 Gy were 68% in the 2D cohort and 18% in the 3D cohort. Conclusions: We could not escalate the dose of gemcitabine with concurrent radiotherapy when using 2D planning because of severe acute esophagitis. However, we could escalate the dose of gemcitabine to 190 mg/m{sup 2}/wk when using 3D planning. The Phase II dose is 150 mg/m{sup 2}/wk. Three-dimensional CRT permitted the use of higher doses of gemcitabine.

    Induction TPF regimen is a standard treatment option for squamous cell carcinoma (SCC) of the oropharynx. The efficacy and safety of adding cetuximab to induction TPF (ETPF) therapy was evaluated. Patients with nonmetastatic resectable stage III/IV SCC of the oropharynx were treated with weekly cetuximab followed the same day by docetaxel and cisplatin and by a continuous infusion of 5-fluorouracil on days 1-5 (every 3 weeks, 3 cycles). The primary endpoint was clinical and radiological complete response (crCR) of primary tumor at 3 months. Secondary endpoints were crCR rates, overall response, pathological CR, progression-free survival, overall survival, and safety. Forty-two patients were enrolled, and 41 received ETPF. The all nine planned cetuximab doses and the full three doses of planned chemotherapy were completed in 31 (76%) and 36 (88%) patients, respectively. Twelve (29%) patients required dose reduction. The crCR of primary tumor at the completion of therapy was observed in nine (22%) patients. ETPF was associated with a tumor objective response rate (ORR) of 58%. The most frequent grade 3–4 toxicities were as follows: nonfebrile neutropenia (39%), febrile neutropenia (19%), diarrhea (10%), and stomatitis (12%). Eighteen (44%) patients experienced acne-like skin reactions of any grade. One toxic death occurred secondary to chemotherapy-induced colitis with colonic perforation. This phase II study reports an interesting response rate for ETPF in patients with moderately advanced SCC of the oropharynx. The schedule of ETPF evaluated in this study cannot be recommended at this dosage. PMID:25684313

    Purpose: The Patterns of Care Study survey process evaluation has been an effective means of assessing the evaluation and treatment practices used by radiation oncologists in the United States for Stage I-II breast cancer. The current 1998-1999 report updates the previous 1989 and 1993-1994 analyses and reflects the recent changes in surgery and systemic therapy observed nationally in the management of early-stage disease. Methods and Materials: A weighted sample size of 71,877 patient records of women treated with breast-conserving surgery and radiotherapy (RT) was obtained from a stratified two-stage sampling of 353 patient records. These cases were centrally reviewed from academic and private radiation oncology practices across the United States. The data collected included patient characteristics, clinical and pathologic factors, and surgical and RT details. The results were compared with those of previous Patterns of Care Study survey reports. Results: Of the patients in the current survey, 97% had undergone mammography before biopsy. A review of the primary tumor pathologic findings indicated improved quantification of an intraductal component from 7.0% in 1993-1994 to 20.4% in 1998-1999 (p = 0.01). The tumor characteristics were better defined, with estrogen and progesterone receptor measurement performed in 91.4% and 91.3% in the 1998-1999 survey vs. 83.7% and 80.3% in the 1989 survey, respectively (p = 0.03 and p = 0.002, respectively). Axillary dissection was performed in 82.2% in the present survey compared with 93.6% in the 1993-1994 survey (p = 0.0004); sentinel node biopsy was performed in 20.1% of the present cases. The use of CT for planning was increased in the current survey, with 22.9% cases CT planned vs. 9% in 1993-1994 (p = 0.10). In the present survey, 100% had received whole breast RT. When a supraclavicular field was added, the dose was prescribed to a specified depth in 67.5% of cases, most commonly 3 cm. When an axillary field was added

    Purpose: To compare the outcomes of four cisplatin-based radiochemotherapy regimens in 311 patients with Stage III/IV squamous cell carcinoma of the head and neck. Methods and Materials: Concurrent chemotherapy consisted of three courses of cisplatin 100 mg/m{sup 2} on Day 1 (Group A, n = 74), two courses of cisplatin 20 mg/m{sup 2} on Days 1-5 plus 5-fluorouracil 1,000 mg/m{sup 2} on Days 1-5 (Group B, n = 49), two courses of cisplatin 20 mg/m{sup 2} on Days 1-5 plus 5-fluorouracil 600 mg/m{sup 2} on Days 1-5 (Group C, n = 102), or two courses of cisplatin 20 mg/m{sup 2} on Days 1-5 (Group D, n = 86). The groups were retrospectively compared for toxicity and outcomes, and 11 additional factors were evaluated for outcomes. Results: No significant difference was observed among the groups regarding radiation-related acute oral mucositis and radiation-related late toxicities. Acute Grade 3 skin toxicity was significantly more frequent in Group B than in the patients of the other three groups (p = .013). The chemotherapy-related Grade 3 nausea/vomiting rate was 24% for Group A, 8% for Group B, 9% for Group C, and 6% for Group D (p = .003). The corresponding Grade 3 nephrotoxicity rates were 8%, 1%, 2%, and 1% (p = .019). The corresponding Grade 3-4 hematologic toxicity rates were 35%, 41%, 19%, and 21% (p = .027). Chemotherapy could be completed in 50%, 59%, 74%, and 83% of the Group A, B, C, and D patients, respectively (p = .002). Toxicity-related radiotherapy breaks occurred in 39%, 43%, 21%, and 15% of Groups A, B, C, and D, respectively (p = .005). The 3-year locoregional control rate was 67%, 72%, 60%, and 59% for Groups A, B, C, and D, respectively (p = .48). The corresponding 3-year metastasis-free survival rates were 67%, 74%, 63%, and 79% (p = .31), and the corresponding 3-year survival rates were 60%, 63%, 50%, and 71% (p = .056).

    Bench runs of a modified V-1710-93 engine equipped with a two-stage supercharger, interstage carburetor, aftercooler assembly, and backfire screens have been made at a simulated altitude of 29,000 feet to determine the effect of several induction-system modifications on the engine and supercharger performance. The standard guide vanes on the auxiliary- and engine-stage superchargers were replaced by rotating guide vanes with a parabolic blade profile. The auxiliary-stage inlet elbow and interstage duct were replaced with new units of NACA design. These modifications were made one at a time and data were obtained after each change to determine the effect of each modification. All runs were made at a constant engine speed of 3000 rpm at a simulated altitude of 29,000 feet and all changes in engine power were made by varying the speed of the auxiliary-stage supercharger.

    Background To report results in terms of feasibility and early toxicity of hypofractionated simultaneous integrated boost (SIB) approach with Volumetric Modulated Arc Therapy (VMAT) as adjuvant treatment after breast-conserving surgery. Methods Between September 2010 and May 2011, 50 consecutive patients presenting early-stage breast cancer were submitted to adjuvant radiotherapy with SIB-VMAT approach using RapidArc in our Institution (Istituto Clinico Humanitas ICH). Three out of 50 patients were irradiated bilaterally (53 tumours in 50 patients). All patients were enrolled in a phase I-II trial approved by the ICH ethical committee. All 50 patients enrolled in the study underwent VMAT-SIB technique to irradiate the whole breast with concomitant boost irradiation of the tumor bed. Doses to whole breast and surgical bed were 40.5 Gy and 48 Gy respectively, delivered in 15 fractions over 3 weeks. Skin toxicities were recorded during and after treatment according to RTOG acute radiation morbidity scoring criteria with a median follow-up of 12 months (range 8–16). Cosmetic outcomes were assessed as excellent/good or fair/poor. Results The median age of the population was 68 years (range 36–88). According to AJCC staging system, 38 breast lesions were classified as pT1, and 15 as pT2; 49 cases were assessed as N0 and 4 as N1. The maximum acute skin toxicity by the end of treatment was Grade 0 in 20/50 patients, Grade 1 in 32/50, Grade 2 in 0 and Grade 3 in 1/50 (one of the 3 cases of bilateral breast irradiation). No Grade 4 toxicities were observed. All Grade 1 toxicities had resolved within 3 weeks. No significant differences in cosmetic scores on baseline assessment vs. 3 months and 6 months after the treatment were observed: all patients were scored as excellent/good (50/50) compared with baseline; no fair/poor judgment was recorded. No other toxicities or local failures were recorded during follow-up. Conclusions The 3-week course of

    We examined the extent to which tauopathy distribution, as determined by Braak staging, might be predicted by various risk factors in older individuals. The Swedish Twin Registry provided extensive information on neuropsychological function, lifestyle, and cardiovascular risk factors of 128 patients for whom autopsy data including Braak staging were available. Logistic regression was used to develop a prognostic model that targeted discrimination between Braak stages 0 to II and III to VI. The analysis showed that Braak stages III to VI were significantly predicted by having 1 or more APOE ε4 alleles, older age, high total cholesterol, absence of diabetes and cardiovascular disease, and poorer scores on the Wechsler Adult Intelligence Score Information test, verbal fluency, and recognition memory but better verbal recall. The algorithm predicted Braak stages III to VI well (receiver-operating characteristic area under curve, 0.897; 95% confidence interval, 0.842-0.951). Using a cutoff of 50% risk or more, the sensitivity was 85%, the specificity was 70%, and the negative predictive value was 69%. This study demonstrates that tauopathy distribution can be accurately predicted using a combination of antemortem patient data. These results provide further insight into tauopathy development and AD-related disease mechanisms and suggest a prognostic model that predicts the spread of neurofibrillary tangles above the transentorhinal stage.

    Background: Currently, there is no uniform consensus regarding the appropriate staging for invasion of the paranasal sinuses in nasopharyngeal carcinoma (NPC). In the current AJCC staging system for NPC, paranasal sinus invasion is defined within the T3 classification. However, according to the Chinese 2008 staging system, which is also widely used in the regions where NPC is endemic in China, paranasal sinus invasion is classified as T4 disease. Methods: Patients (n = 1811) with non-metastatic, histologically-proven NPC treated with intensity-modulated radiotherapy (IMRT) were retrospectively analyzed. Results: Paranasal sinus invasion was identified in 289/1811 patients (16.0%). Multivariate analysis revealed ethmoid sinus invasion (HR, 2.889; 95% CI, 1.362-6.131; P = 0.006) and maxillary sinus invasion (HR, 3.110; 95% CI, 1.439-6.721; P = 0.004) were independent prognostic factors for local relapse-free survival (LRFS). T3 patients with ethmoid sinus or maxillary sinus invasion had similar 3-year LRFS (83.6% vs. 92.2%, P = 0.132) as T4 patients, and had poorer LRFS (83.6% vs. 98.3%, P = 0.006) than T3 patients with sphenoid sinus invasion alone. Also, T3 patients with sphenoid sinus invasion alone had similar 3-year LRFS (98.3 vs. 96.4%, P = 0.391) as T3 patients without paranasal sinus invasion, and a trend toward higher LRFS (98.3% vs. 92.2%, P = 0.065) than T4 patients. Conclusion: In patients underwent IMRT, tumors with ethmoid sinus or maxillary sinus invasion had a higher risk of local failure than those with sphenoid sinus invasion alone. Sphenoid sinus invasion alone should be classified as T3 disease and ethmoid sinus or maxillary sinus involvement as T4 disease in the current AJCC staging system for NPC. PMID:27390611

    Stage I/IIA follicular lymphoma (FL) is considered a localised disease that can be adequately treated with radiotherapy alone. Bone marrow (BM) and peripheral blood (PB) involvement in FL was investigated by polymerase chain reaction (PCR) in a series of 24 consecutive patients with histologically revised diagnosis and treated with involved field radiotherapy. Despite the limited stage, Bcl-2/IgH+ cells were found at diagnosis in PB and/or BM of 16 patients (66.6%). After treatment, in 9/15 Bcl-2/IgH positive evaluable patients, a disappearance of Bcl-2/IgH+ cells was observed, which persisted after a median follow-up of 43.5 months (range 11-70) in all but one patient. Quantitative PCR demonstrated the feasibility of clearing PB and BM Bcl-2+ cells after local irradiation of the primary site of the disease only when the basal number of lymphoma cells was <1:100 000. Patients with Bcl-2/IgH+ cells at diagnosis or after treatment had a higher likelihood of relapse. Thus, despite a negative BM biopsy, the majority of localised FL Bcl-2/IgH+ cells were found in the PB and BM. Lymphoma cells can reversibly spread from the affected lymph node to PB and BM and, in a proportion of cases, durably disappear after irradiation. The possibility of a persistent lymphoma cell clearance is proportional to the amount of cells detected at presentation by quantitative PCR. PMID:17408460

    Tumor, lymph node, and metastasis (TNM) classification of lung cancer is typically performed with the TNM staging system, as recommended by the Union Internationale Contre le Cancer (UICC), the American Joint Committee on Cancer (AJCC), and the International Association for the Study of Lung Cancer (IASLC). Radiologic examinations for TNM staging of lung cancer patients include computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography with 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG-PET), and FDG-PET combined with CT (FDG-PET/CT) and are used for pretherapeutic assessments. Recent technical advances in MR systems, application of fast and parallel imaging and/or introduction of new MR techniques, and utilization of contrast media have markedly improved the diagnostic utility of MRI in this setting. In addition, FDG-PET can be combined or fused with MRI (PET/MRI) for clinical practice. This review article will focus on these recent advances in MRI as well as on PET/MRI for lung cancer staging, in addition to a discussion of their potential and limitations for routine clinical practice in comparison with other modalities such as CT, FDG-PET, and PET/CT.

    Aberrant expression of miRNAs and their biogenesis factors has been frequently observed in different types of cancer. We recently reported that expression of DICER1 is reduced in metastatic melanoma. Nevertheless, so far very little is known about the expression pattern of other miRNA biogenesis factors in this type of malignancy. Here, we investigated the expression pattern of DROSHA in a large set of melanocytic lesions by tissue microarray and immunohistochemistry (n = 409). We found that nuclear expression of DROSHA is markedly reduced in the early stages of melanoma progression (P = 0.0001) and is inversely correlated with melanoma thickness (P = 0.0001), AJCC stages (P = 0.0001), and ulceration status (P = 0.002). We also confirmed the reduced expression of nuclear DROSHA by a second specific antibody raised against a different region of the DROSHA protein. In addition, we observed that the reduced nuclear expression of DROSHA during melanoma progression is accompanied by an increased cytoplasmic expression of this protein (P = 0.0001). Finally, we found that expression pattern of DROSHA varies from that of DICER1 and concomitant loss of expression of both DICER1 and DROSHA confers the worse outcome for melanoma patients. Our results demonstrate a reduced nuclear expression of DROSHA which further highlights a perturbed miRNA biogenesis pathway in melanoma. In addition, the aberrant subcellular localization of DROSHA indicates possible deregulation in the mechanisms responsible for its proper localization in the nucleus. PMID:23370771

    Incidence and mortality of intrahepatic cholangiocarcinoma (ICC) are increasing. However, its prognostic predictive system associated with outcome after surgery remains poorly defined. In this study, we conducted retrospective survival analyses in a primary cohort of 370 patients who underwent partial hepatectomy for ICC (2005 and 2009). We found that seven variables were significantly independent predictors for overall survival (OS): serum prealbumin (hazard ratio [HR]: 1.447; p = 0.015), carbohydrate antigen 19-9 (HR: 1.438; p = 0.009), carcinoembryonic antigen (HR: 1.732; p = 0.002), tumor number (HR: 1.781; p < 0.001), vascular invasion (HR: 1.784; p < 0.001), regional lymphatic metastasis (HR: 2.003; p < 0.001) and local extrahepatic metastasis (HR: 1.506; p = 0.008). Using these independent predictors, we created a simple clinicopathologic prognostic staging system for predicting survival of ICC patients after resection. The validity of the prognostic staging system was prospectively assessed in 115 patients who underwent partial hepatectomy between January 2010 and December 2010 at the same institution. The prognostic power was quantified using likelihood ratio test and Akaike information criteria. Compared with the 6th and 7th AJCC staging systems, the new staging system in the primary cohort had a higher predictive accuracy for OS in terms of homogeneity and discriminatory ability. In the validation cohort, the homogeneity and discrimination of the new staging system were also superior to the two other staging systems. Conclusions: The new staging system based on clinicopathologic features may provide relatively higher accuracy in prognostic prediction for ICC patients after tumor resection. PMID:26175951

    This trial compared the efficacy and toxicity of standard first-line treatment with paclitaxel/carboplatin versus paclitaxel/carboplatin plus sorafenib in patients with advanced ovarian carcinoma. Patients with stage 3 or 4 epithelial ovarian cancer with residual measurable disease or elevated CA-125 levels after maximal surgical cytoreduction were randomized (1:1) to receive treatment with paclitaxel (175 mg/m2, 3 h infusion, day 1) and carboplatin (AUC 6.0, IV, day 1) with or without sorafenib 400 mg orally twice daily (PO BID). Patients were reevaluated for response after completing 6 weeks of treatment (two cycles); responding or stable patients received six cycles of paclitaxel/carboplatin. Patients receiving the sorafenib-containing regimen continued sorafenib (400 PO BID) for a total of 52 weeks. Eighty-five patients were randomized and received treatment.Efficacy was similar for patients receiving paclitaxel/carboplatin/sorafenib versus paclitaxel/carboplatin: overall response rates 69% versus 74%; median progression-free survival 15.4 versus 16.3 months; 2 year survival 76% versus 81%. The addition of sorafenib added substantially to the toxicity of the regimen; rash, hand–foot syndrome, mucositis, and hypertension were significantly more common in patients treated with sorafenib. The addition of sorafenib to standard paclitaxel/carboplatin did not improve efficacy and substantially increased toxicity in the first-line treatment of advanced epithelial ovarian cancer. Based on evidence from this study and other completed trials, sorafenib is unlikely to have a role in the treatment of ovarian cancer. PMID:25556916

    The purpose of our study was to test the predictive value of cisplatin-DNA adduct levels in head and neck squamous cell carcinoma (HNSCC) patients treated with cisplatin-radiation. Patients with advanced-stage HNSCC were treated within a randomized trial, investigating the optimal route of cisplatin administration, concurrently with radiation. Cisplatin was administered intra-arterially (IA, 150 mg/m2, with systemic rescue by sodium thiosulfate) or intravenously (IV, 100 mg/m2). In a subgroup, adducts were quantified in normal tissue and tumor. 32P-postlabeling was used to quantify intrastrand guanosine-guanosine adducts (GG-adducts) and adenosine-guanosine adducts (AG-adducts). Adduct levels were correlated with treatment outcome. Thirty-five patients were included (21 IV and 14 IA). At median follow-up of 27 months, locoregional (LR) control was 75% at 1 and 70% at 2 years. Adduct levels in tumor were 4-5-fold higher than in white blood cells (WBC) for both IA and IV treatment (p = 0.01). Adduct formation in WBC and buccal cells was higher in IV treated patients compared with IA infusion (p = 0.049 and 0.005 for GG-adducts in WBC and buccal cells, respectively). Adducts in tumors after IA infusion were not statistically different from those after IV. A strong correlation was observed between GG- and AG-adduct formation (r = 0.86, p < 0.001). Patients with higher GG adduct levels (>median) in primary tumor had significantly better disease free survival (DFS) than patients with lower (< or = median) adduct levels (p = 0.02). For overall survival (OS), a nonsignificant trend was observed, again in favor of patients with higher adduct levels (p = 0.06). In conclusion, cisplatin-DNA adduct formation in primary tumor appears to be predictive for DFS in HNSCC. No differences were observed in intratumoral adduct levels between IA and IV treatments, despite selective infusion of high-dose cisplatin with the IA procedure. However, systemic adduct levels (WBC and buccal

    Purpose One third of patients with triple-negative breast cancer (TNBC) achieve pathologic complete response (pCR) with standard neoadjuvant chemotherapy (NACT). CALGB 40603 (Alliance), a 2 × 2 factorial, open-label, randomized phase II trial, evaluated the impact of adding carboplatin and/or bevacizumab. Patients and Methods Patients (N = 443) with stage II to III TNBC received paclitaxel 80 mg/m2 once per week (wP) for 12 weeks, followed by doxorubicin plus cyclophosphamide once every 2 weeks (ddAC) for four cycles, and were randomly assigned to concurrent carboplatin (area under curve 6) once every 3 weeks for four cycles and/or bevacizumab 10 mg/kg once every 2 weeks for nine cycles. Effects of adding these agents on pCR breast (ypT0/is), pCR breast/axilla (ypT0/isN0), treatment delivery, and toxicities were analyzed. Results Patients assigned to either carboplatin or bevacizumab were less likely to complete wP and ddAC without skipped doses, dose modification, or early discontinuation resulting from toxicity. Grade ≥ 3 neutropenia and thrombocytopenia were more common with carboplatin, as were hypertension, infection, thromboembolic events, bleeding, and postoperative complications with bevacizumab. Employing one-sided P values, addition of either carboplatin (60% v 44%; P = .0018) or bevacizumab (59% v 48%; P = .0089) significantly increased pCR breast, whereas only carboplatin (54% v 41%; P = .0029) significantly raised pCR breast/axilla. More-than-additive interactions between the two agents could not be demonstrated. Conclusion In stage II to III TNBC, addition of either carboplatin or bevacizumab to NACT increased pCR rates, but whether this will improve relapse-free or overall survival is unknown. Given results from recently reported adjuvant trials, further investigation of bevacizumab in this setting is unlikely, but the role of carboplatin could be evaluated in definitive studies, ideally limited to biologically defined patient subsets most likely

    Timing of orthodontic treatment, especially for children with developing class III malocclusions, has always been somewhat controversial, and definitive treatment tends to be delayed for severe class III cases. Developing class III patients with moderate to severe anterior crossbite and deep bite may need early intervention in some selected cases. Class III malocclusion may develop in children as a result of an inherent growth abnormality, i.e. true class III malocclusion, or as a result of premature occlusal contacts causing forward functional shift of the mandible, which is known as pseudo class III malocclusion. These cases, if not treated at the initial stage of development, interfere with normal growth of the jaw bases and may result in severe facial deformities. The treatment should be carried out as early as possible for permitting normal growth of the skeletal bases. This paper deals with the selection of an appropriate appliance from the various current options available for early intervention in developing class III malocclusion through two case reports.

    About a third of patients with pancreatic cancer present with locally advanced disease that is not amenable to resection. Because these patients have localized disease, conventional ablative therapies (thermal ablation and cryoablation) have the potential to be beneficial, but their use is inherently limited in the pancreas. These limitations could be overcome by irreversible electroporation-a novel, non-thermal ablative method that is gaining popularity for the treatment of many soft tissue tumors, including those of the pancreas. This review summarizes the status of this technique in the treatment of locally advanced pancreatic cancer. Most of the evidence on efficacy and safety is based on non-randomized prospective series, which show that irreversible electroporation may improve overall survival and pain control in locally advanced pancreatic cancer. As experience with this procedure increases, randomized controlled trials are needed to document its efficacy in locally advanced pancreatic cancer more precisely. PMID:25787829

    Summary Background To establish computed tomography (CT) staging of middle ear cholesteatoma and assess its impact on the selection of the surgical procedure. Material/Methods Prospective study was conducted on 61 consecutive patients (mean age 26.8 years) with middle ear cholesteatoma. CT scan of the temporal bone and surgery were performed in all patients. CT staging classified cholesteatoma according to its location in the tympanic cavity (T); extension into the mastoid (M); and associated complications (C). Cholesteatoma was staged as stage I (T1, T2), stage II (T3, M1, M2, C1), and stage III (C2). Results The overall sensitivity of CT staging of cholesteatoma compared to surgery was 88% with excellent agreement and correlation between CT findings and intra-operative findings (K=0.863, r=0.86, P=0.001). There was excellent agreement and correlation of CT staging with surgical findings for T location (K=0.811, r=0.89, P=0.001), good for M extension (K=0.734, r=0.88, P=0.001), and excellent for associated C complications (K=1.00, r=1.0, P=0.001). Atticotympanotomy was carried out in stage I (n=14), intact canal wall surgery was performed in stage II (n=38), and canal wall down surgery was done in stage III (n=5) and stage II (n=4). Conclusions We established CT staging of middle ear cholesteatoma that helps surgeons to select an appropriate surgery. PMID:26171086

    Motta, G; Nahum, M A; Testa, T; Spinelli, E

    1995-01-01

    The TNM System as originally proposed by Denoix in 1946, provides a consistent, reproducible description of the anatomic extent of disease in cancer patients at a specific time in the life history of the cancer. C.F. Mountain first adapted this classification to lung cancer in 1973 on behalf of AJCC. In 1986 he presented the "New Intl. Staging System for Lung Cancers" mainly based on a 13 yr experience of the previous one, which was accepted world-wide through a round of international consensus meetings held in 1985. Clinical Staging is the best estimate of disease extent made prior to the institution of any therapy; Surgical-pathological Staging is the classification of disease extent as determined from pathological examination of resected specimens. Accordingly, once the diagnosis is made, it is necessary to stage accurately the tumour determining the size and location of the tumour (T status), the presence or absence of lymphnode involvement (N status), and whether the tumour is metastatic to distant sites (M status). Moreover the uniform staging criteria for lung cancer will assure for each patient the better selection of treatment, the evaluation of operability, the need for adjuvant therapy, as well as the estimation of prognosis. Equally important is the resultant ability to compare the outcome of treatment protocols from different centres. More recently C.F. Mountain has added to the Staging System a new standard logic or "convention" for classifying infrequently observed presentations of lung cancer with which the standard rules of Staging System itself don't fit. These conventions are based on empiric expectation for treatment selection and survival that are similar to those for the Staging definitions, which are based on actuarialsurvival data. Many different types of tumour such as multiple masses, synchronous multiple primitives, discontinuous tumour foci in visceral or parietal pleura as well neoplastic involvement of various mediastinal structures

    Background The 7th edition of the American Joint Committee on Cancer (AJCC) staging system has recently been validated and shown to predict survival in patients with intrahepatic cholangiocarcinoma (ICC). The present study attempted to investigate the validity of these findings. Methods A single-centre, retrospective cohort study was conducted. Histopathological restaging of disease subsequent to primary surgical resection was carried out in all consecutive ICC patients. Overall survival was compared using Kaplan–Meier estimates and log-rank tests. Results A total of 150 patients underwent surgery, 126 (84%) of whom met the present study's inclusion criteria. Of these 126 patients, 68 (54%) were female. The median length of follow-up was 4.5 years. The median patient age was 58 years (range: 24–79 years). Median body mass index was 27 kg/m2 (range: 17–46 kg/m2). Staging according to the AJCC 7th edition categorized 33 (26%) patients with stage I disease, 27 (21%) with stage II disease, five (4%) with stage III disease, and 61 (48%) with stage IVa disease. The AJCC 7th edition failed to accurately stratify survival in the current cohort; analysis revealed significantly worse survival in those with microvascular invasion, tumour size of >5 cm, grade 4 disease, multiple tumours and positive lymph nodes (P < 0.001). A negative resection margin was associated with improved survival (P < 0.001). Conclusions The AJCC 7th edition did not accurately predict survival in patients with ICC. A multivariable model including tumour size and differentiation in addition to the criteria used in the AJCC 7th edition may offer a more accurate method of predicting survival in patients with ICC.

    Background The objective is to assess how cancer patients know about their diagnosis what they know about their real stage, and the relationship between cancer stage and psychological distress. Methods A questionnaire including the Distress Thermometer was delivered to 422 cancer inpatients. Multivariate logistic regression analysis was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Results Most of patients (68.7%) knew the bad news immediately after diagnosis. Half of patients knew their diagnosis directly from medical reports. Nearly one third of patients were informed by doctors. Cancer stages, which patients believed, differed significantly from their real disease stages (P<0.001). Over half of patients did not know their real disease stages. Patients with stage I–III cancer were more likely to know their real disease stage than patients with stage IV cancer (P<0.001). Distress scores of cancer patients were determined by the real cancer stage (P=0.012), not the stage which patients believed. Conclusions Although most of participants knew the bad news immediately after diagnosis, less than half of them knew their real disease stage. Patient with stage I–III cancer was more likely to know the real disease stage and had a DT score <4 than patient with stage IV disease. PMID:27004220

  17. The seventh tumour-node-metastasis staging system for lung cancer: Sequel or prequel?

    2013-09-01

    Anatomical cancer extent is an important predictor of prognosis and determines treatment choices. In non-small-cell lung cancer (NSCLC) the tumour-node-metastasis (TNM) classification developed by Pierre Denoix replaced in 1968 the Veterans Administration Lung cancer Group (VALG) classification, which was still in use for small-cell lung cancer (SCLC). Clifton Mountain suggested several improvements based on a database of mostly surgically treated United States (US) patients from a limited number of centres. This database was pivotal for a uniform reporting of lung cancer extent by the American Joint Committee of Cancer (AJCC) and the International Union against Cancer (IUCC), but it suffered increasingly from obsolete diagnostic and staging procedures and did not reflect new treatment modalities. Moreover, its findings were not externally validated in large Japanese and European databases, resulting in persisting controversies which could not be solved with the available database. The use of different mediastinal lymph-node maps in Japan, the (US) and Europe facilitated neither the exchange nor the comparison of treatment results. Peter Goldstraw, a United Kingdom (UK) thoracic surgeon, started the process of updating the sixth version in 1996 and brought it to a good end 10 years later. His goals were to improve the TNM system in lung cancer by addressing the ongoing controversies, to validate the modifications and additional descriptors, to validate the TNM for use in staging SCLC and carcinoid tumours, to propose a new uniform lymph-node map and to investigate the prognostic value of non-anatomical factors. A staging committee was formed within the International Association for the Study of Lung Cancer (IASLC) - which supervised the collection of the retrospective data from >100,000 patients with lung cancer - treated throughout the world between 1990 and 2000, analyse them with the help of solid statistics and validate externally with the Surveillance

    1986-06-01

    From 1980 to 1984, 72 patients with impingement syndrome were treated by anterior acromioplasty before they developed rotator cuff tears. Follow-up evaluations averaged 23 months (range, five to 48 months). The average age was 42 years (range, 23-61 years). Preoperatively, 80% of the patients had pain at rest; the other 20% complained of pain during moderate activity. At the time of follow-up examination, 89% showed significant improvement, while 11% remained unchanged. Thirty-seven percent of the patients had varying degrees of muscle weakness preoperatively; of these, 71% were improved, 21% were unchanged, and 8% had a further decrease in the range of motion postoperatively. The results indicate that anterior acromioplasty is an excellent procedure for relief of pain due to impingement. Additionally, beneficial results were obtained in range of motion and muscle strength. In only a few select cases was lateral clavicle excision or tenodesis of the long head of the biceps necessary. Caution is advised in allowing return to strenuous activity unless the patient has recovered adequate strength in the cuff musculature. PMID:3720075

    In the Payload Hazardous Servicing Facility, the integrated Mars Observer/Transfer Orbit Stage (TOS) payload is ready for encapsulation in the Titan III nose fairing. The TOS booster maiden flight was dedicated to Thomas O. Paine, a former NASA administrator who strongly supported interplanetary exploration and was an early backer of the TOS program. Launched September 25, 1992 from the Kennedy Space Flight Center aboard a Titan III rocket and the TOS, the Mars Observer spacecraft was to be the first U.S. spacecraft to study Mars since the Viking missions 18 years prior. Unfortunately, the Mars Observer spacecraft fell silent just 3 days prior to entering orbit around Mars.

  2. Ovarian, fallopian tube and peritoneal cancer staging: Rationale and explanation of new FIGO staging 2013.

    PubMed

    Prat, Jaime

    2015-08-01

    Ovarian, fallopian tube, and peritoneal cancers have a similar clinical presentation and are treated similarly, and current evidence supports staging all three cancers in a single system. The primary site (i.e., ovary, fallopian tube, or peritoneum) should be designated where possible. The histologic type should be recorded. Intraoperative rupture ("surgical spill") is IC1; capsule ruptured before surgery or tumor on ovarian or fallopian tube surface is IC2; and positive peritoneal cytology with or without rupture is IC3. The new staging includes a revision of stage III patients; assignment to stage IIIA1 is based on spread to the retroperitoneal lymph nodes without intraperitoneal dissemination. Extension of the tumor from the omentum to the spleen or liver (stage IIIC) should be differentiated from isolated parenchymal metastases (stage IVB). PMID:25890882

    Purpose: To investigate, in a comparative analysis, the prognostic implications of postchemoradiotherapy (post-CRT) pathologic stage (ypStage) vs. postoperative pathologic stage (pStage) in rectal cancer. Methods and Materials: Between May 2001 and December 2006, 487 patients with T3 mid or distal rectal cancer were analyzed retrospectively. Concurrent CRT was administered preoperatively (n = 364, 74.7%) or postoperatively (n = 123, 25.3%). The radiation dose was 50.4 Gy in 28 fractions. All patients underwent a total mesorectal excision and received adjuvant chemotherapy. Disease-free survival (DFS) was estimated using the Kaplan-Meier method. Differences in DFS, stratified by ypStage and pStage, were compared using the log-rank test. Results: For surviving patients, the median follow-up period was 68 months (range, 12-105 months). The 5-year local recurrence-free survival rate was not different, at 95.3% and 92.1% in preoperative and postoperative CRT groups, respectively (p = 0.402), but the 5-year distant metastasis-free survival rate was significantly different, at 81.6% (preoperative CRT) vs. 65.4% (postoperative CRT; p = 0.001). The 5-year DFS rate of 78.8% in the preoperative CRT group was significantly better than the 63.0% rate in the postoperative CRT group (p = 0.002). Post-CRT pathologic Stage 0-I occurred in 42.6% (155 of 364) of the patients with preoperative CRT. The 5-year DFS rates were 90.2% (ypStage 0-I), 83.5% (ypStage II), 77.3% (pStage II), 58.6% (ypStage III), and 54.7% (pStage III). The DFS rate of ypStage 0-I was significantly better than that of ypStage II or pStage II. Post-CRT pathologic Stage II and III had similar DFS, compared with pStage II and III, respectively. Conclusions: Disease-free survival predicted by each ypStage was similar to that predicted by the respective pStage. Improved DFS with preoperative vs. postoperative CRT was associated with the ypStage 0-I group that showed a similarly favorable outcome to pStage I rectal

    Background. Pegfilgrastim is widely used for the prevention of chemotherapy-induced neutropenia. In highly regulated markets, there are currently no approved biosimilars of pegfilgrastim. Pegfilgrastim Randomized Oncology (Supportive Care) Trial to Evaluate Comparative Treatment (PROTECT-2) was a confirmatory efficacy and safety study designed to compare proposed biosimilar LA-EP2006 with reference pegfilgrastim (Neulasta, Amgen) in early-stage breast cancer patients receiving adjuvant or neoadjuvant myelosuppressive chemotherapy. Methods. A total of 308 patients were randomized to LA-EP2006 or reference pegfilgrastim. Each patient received TAC (intravenous docetaxel 75 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2) on day 1 of each cycle, for six or more cycles. Pegfilgrastim (LA-EP2006 or reference) was given subcutaneously (6 mg in 0.6 mL) on day 2 of each cycle. The primary endpoint was duration of severe neutropenia (DSN) during cycle 1 (number of consecutive days with an absolute neutrophil count <0.5 × 109/L), with equivalence confirmed if 90% and 95% confidence intervals (CIs) were within a 1-day margin. Results. Baseline characteristics were well balanced. DSN was equivalent between groups at mean ± SD 1.36 ± 1.13 (LA-EP2006, n = 155) and 1.19 ± 0.98 (reference, n = 153) in cycle 1. With a treatment difference (reference minus LA-EP2006) of −0.16 days (90% CI −0.36 to 0.04; 95% CI −0.40 to 0.08), LA-EP2006 was equivalent to reference pegfilgrastim. Secondary efficacy parameters were similar between groups during cycle 1 and across cycles. Safety profiles were also similar between groups. No neutralizing antibodies against pegfilgrastim, filgrastim, or polyethylene glycol were detected. Conclusion. LA-EP2006 and reference pegfilgrastim were therapeutically equivalent and comparable regarding efficacy and safety in the prevention of neutropenia in patients with early-stage breast cancer receiving TAC.

    This is the third in the series of reports covering the Fusion Power Demonstration (FPD) design study. This volume considers the FPD-III configuration that incorporates an octopole end plug. As compared with the quadrupole end-plugged designs of FPD-I and FPD-II, this octopole configuration reduces the number of end cell magnets and shortens the minimum ignition length of the central cell. The end-cell plasma length is also reduced, which in turn reduces the size and cost of the end cell magnets and shielding. As a contiuation in the series of documents covering the FPD, this report does not stand alone as a design description of FPD-III. Design details of FPD-III subsystems that do not differ significantly from those of the FPD-II configuration are not duplicated in this report.

    Background: Patients with UICC/AJCC stage II colon cancer have a high 5-year overall survival rate after surgery. Nevertheless, a significant subgroup of patients develops tumour recurrence. Currently, there are no clinically established biomarkers available to identify this patient group. We applied reverse-phase protein arrays (RPPA) for phosphatidylinositide-3-kinase pathway activation mapping to stratify patients according to their risk of tumour recurrence after surgery. Methods: Full-length proteins were extracted from formalin-fixed, paraffin-embedded tissue samples of 118 patients who underwent curative resection. RPPA technology was used to analyse expression and/or phosphorylation levels of six major factors of the phosphatidylinositide-3-kinase pathway. Oncogenic mutations of KRAS and BRAF, and DNA microsatellite status, currently discussed as prognostic markers, were analysed in parallel. Results: Expression of phospho-AKT (HR=3.52; P=0.032), S6RP (HR=6.3; P=0.044), and phospho-4E-BP1 (HR=4.12; P=0.011) were prognostic factors for disease-free survival. None of the molecular genetic alterations were significantly associated with prognosis. Conclusions: Our data indicate that activation of the PI3K/AKT pathway evidenced on the protein level might be a valuable prognostic marker to stratify patients for their risk of tumour recurrence. Beside adjuvant chemotherapy targeting of upregulated PI3K/AKT signalling may be an attractive strategy for treatment of high-risk patients. PMID:24619078

    1986-01-01

    The work hardening of fcc metals at large strains is discussed with reference to the linear stress-strain behavior often observed at large strains and known as Stage IV. The experimental evidence shows that Stage IV is a work hardening phenomenon that is found quite generally, even in pure fcc metals subjected to homogeneous deformation. A simple model for Stage IV in pure metals is presented, based on the accumulation of dislocation debris. Experiments are described for large strain torsion tests on four aluminum alloys. The level and extent of Stage IV scaled with the saturation stress that would represent the end of Stage III in the absence of a Stage IV. Reversing the torsion after large prestrains produced transient reductions in the work hardening. The strain rate sensitivity was also measured before and during the transient and found not to vary significantly. The microstructure observed at large strains in an Mg alloy suggest that Stage IV can occur in the absence of microband formation. Previous proposals for the cause of Stage IV are reviewed and found to be not supported by recent experimental data.

    Objective To evaluate treatment outcomes for patients with vulvar cancer with grossly positive pelvic lymph nodes (PLNs). Methods From a database of 516 patients with vulvar cancer, we identified patients with grossly positive PLNs without distant metastasis at initial diagnosis. We identified 20 patients with grossly positive PLNs; inclusion criteria included PLN 1.5 cm or larger in short axis dimension on CT/MRI (n=11), FDG-avid PLN on PET/CT (n=3), or biopsy-proven PLN disease (n=6). Ten patients were treated with chemoradiation (CRT) therapy, 4 with RT alone, and 6 with various combinations of surgery, RT or CRT. Median follow-up time for patients who had not died of cancer was 47 months (range, 4-228 months). Results Mean primary vulvar tumor size was 6.4 cm; 12 patients presented with 2009 AJCC T2 and 8 with T3 disease. All patients had grossly positive inguinal nodes, and the mean inguinal nodal diameter was 2.8 cm. The 5-year overall survival and disease specific survival rates were 43% and 48%, respectively. Eleven patients had recurrences, some at multiple sites. There were 9 recurrences in the vulva, but no isolated nodal recurrences. Four patients developed distant metastasis within 6 months of starting radiation therapy. Conclusions Aggressive locoregional treatment can lead to favorable outcomes for many patients with grossly involved PLNs that is comparable to that of grossly involved inguinal nodes only. We recommend modification of the FIGO stage IVB classification to more accurately reflect the relatively favorable prognosis of patients with PLN involvement. PMID:25524458

    Background The aim of the study is to investigate differences in clinical presentation, disease stage and survival of operable pancreatic cancer patients with new onset DM compared to long standing diabetes mellitus (DM) and non diabetics. Methods A prospectively maintained pancreatic cancer surgery database of a tertiary care teaching hospital from January 2006 to August 2012 was reviewed. Only patients with a histological diagnosis of pancreatic carcinoma (PC) were included in final analysis. DM was defined as HbA1c >6.5% or any patient on anti-diabetic treatment regardless of HbA1c value. New onset DM was defined when diagnosed within two preceding years of surgery. Patients were stratified into two groups: DM and non DM. Among the DM patients, patients with new onset DM were further stratified and studied separately. Staging of PC was performed according to the 6th edition of AJCC. Survival of patients with PC was determined by reviewing medical records. Patients and their families were contacted if there was no existing follow-up. Results Eighty-six patients (n=55, 63.9% male) with a mean age of 62 years (range, 29-85 years) underwent pancreatic cancer surgery during the study period. Of the 86 patients, 30 (34%) had DM of which eight patients (9% overall) had new onset DM. DM patients tended to be older compared to non DM patients (67.8 vs. 58.5 years, P=0.0005). The majority of non DM patients were symptomatic (98.2%), and there was a tendency for DM group patients to be asymptomatic at presentation (13.3% vs. 1.8%, P=0.05). Abdominal pain was less common in DM patients compared to non DM patients (30% vs. 53.6%, P=0.04). The median duration of new onset DM prior to diagnosis of PC was 2 months (range, 1-23 months). There was a tendency for DM patients to present at an early stage (stage I and stage II) (P=0.08). There was no difference in survival (P=0.17) for new onset DM compared to long standing DM and non DM patients. Conclusions DM patients tend to be

    BACKGROUND: Video-assisted thoracoscopic surgical decortication (VATSD) is widely applicable in fibrinopurulent Stage II empyema. While, more chronic thick walled Stage III empyema (organizing stage) needs conversion to open thoracotomy, and existing reports reveal a lacuna in the realm of late stage empyema patient's management through VATS utilization, particularly Stage III empyema. We prospectively evaluated the application of VATSD regardless of the stage of pleural empyema for the effective management of late stage empyema in comparison to open decortications (ODs) to minimize the adverse effects of the disease. METHODS: All patients with pyogenic pleural empyema (Stage II and Stage III) in King Khalid University Hospital (KKUH) (admitted from January 2009 to December 2013) who did not respond to chest tube/pigtail drainage and/or antibiotic therapy were treated with VATSD and/or open thoracotomy. Prospective evaluation was carried out, and the effect of this technique on perioperative outcomes was appraised to evaluate our technical learning with the passage of time and experience with VATS for late stage empyema management. RESULTS: Out of total 63 patients, 26 had Stage II empyema and 37 had Stage III empyema. VATSD was employed on all empyema patients admitted in the KKUH. VATSD was successful in all patients with Stage II empyema. Twenty-five patients (67.6%) with Stage III empyema completed VATSD successfully. However, only 12 cases (32.4%) required conversions to open (thoracotomy) drainage (OD). The median hospital stay for Stage III VATSD required 9.65 ± 4.1 days. Whereas, patients who underwent open thoracotomy took longer time (21.82 ± 16.35 days). Similarly, Stage III VATSD and Stage III open surgery cases showed significance difference among chest tube duration (7.84 ± 3.33 days for VATS and 15.92 ± 8.2 days for open thoracotomy). Significantly, lower postoperative complications were detected in patients treated with VATSD in terms of

    1969-01-01

    The Hyper III was a full-scale lifting-body remotely piloted research vehicle (RPRV) built at what was then the NASA Flight Research Center located at Edwards Air Force Base in Southern California. The Flight Research Center (FRC--as Dryden was named from 1959 until 1976) already had experience with testing small-scale aircraft using model-airplane techniques, but the first true remotely piloted research vehicle was the Hyper III, which flew only once in December 1969. At that time, the Center was engaged in flight research with a variety of reentry shapes called lifting bodies, and there was a desire both to expand the flight research experience with maneuverable reentry vehicles, including a high-performance, variable-geometry craft, and to investigate a remotely piloted flight research technique that made maximum use of a research pilot's skill and experience by placing him 'in the loop' as if he were in the cockpit. (There have been, as yet, no female research pilots assigned to Dryden.) The Hyper III as originally conceived was a stiletto-shaped lifting body that had resulted from a study at NASA's Langley Research Center in Hampton, Virginia. It was one of a number of hypersonic, cross-range reentry vehicles studied at Langley. (Hypersonic means Mach 5--five times the speed of sound--or faster; cross-range means able to fly a considerable distance to the left or right of the initial reentry path.) The FRC added a small, deployable, skewed wing to compensate for the shape's extremely low glide ratio. Shop personnel built the 32-foot-long Hyper III and covered its tubular frame with dacron, aluminum, and fiberglass, for about $6,500. Hyper III employed the same '8-ball' attitude indicator developed for control-room use when flying the X-15, two model-airplane receivers to command the vehicle's hydraulic controls, and a telemetry system (surplus from the X-15 program) to transmit 12 channels of data to the ground not only for display and control but for data

    In patients with malignant tumors, the TNM classification has been widely used by clinicians as a guide for estimating prognosis, and is the basis for treatment decisions. Recently, the International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee and the International Thymic Malignancy Interest Group have proposed a new classification for thymic malignancies to be included in the next official staging system of the forthcoming 8th edition of the TNM classification. In this study, we reviewed 154 consecutive patients with thymic epithelial tumors who underwent complete resection at our institution, and compared their characteristics and outcomes when classified according to the proposed system with those when classified under the current Masaoka-Koga system. The proportion of patients with stage I disease increased markedly to 77.3%under the proposed system because a certain number of patients with Masaoka-Koga stages II and III diseases were downstaged to the new stage I. Regarding histology, among 69 patients with type A, AB, or B1 thymoma, 68 tumors(99%)were diagnosed as new stage I disease. When using the proposed system, the recurrence-free survival rates showed significant deterioration with increasing stage, while the overall survival rates did not. Although the new TNM classification does not serve as an effective prognostic prediction model for overall survival, it appears to offer some benefit, especially in the analysis of recurrence-free survival.

  10. Fueling type III secretion

    Type III secretion systems are complex nanomachines that export proteins from the bacterial cytoplasm across the cell envelope in a single step. They are at the core of the machinery used to assemble the bacterial flagellum, and the needle complex many Gram-negative pathogens use to inject effector proteins into host cells and cause disease. Several models have been put forward to explain how this export is energized, and the mechanism has been the subject of considerable debate. Here we present an overview of these models and discuss their relative merits. Recent evidence suggests that the proton motive force is the primary energy source for type III secretion, although contribution from refolding of secreted proteins has not been ruled out. The mechanism, by which the proton motive force is converted to protein export, remains enigmatic. PMID:25701111

  12. Migration Type III

    Migration type IIIMigration of objects embedded in disks (and the accompanying eccentricity evolution) is becoming a major theme in planetary system formation.The underlying physics can be distilled into the notion of disk-planet coupling via Lindblad resonances, which launch waves, sometimes spectacular spiral shock waves in gas disks. The wave pattern exchanges angular momentum with the planet. That causes (i) migration, (ii) eccentricity evolution, and (iii) gap opening by sufficiently massive planets.A competing source of disk-planet interaction, the corotationaltorques, are much less conspicuous (corotation does not produce easilydetectable waves, as galaxy observers can attest) and have often been missed in the analysis of planet migration. If spiral waves are like waves at Goleta beach, then the corotation acts more like a stealthy riptide. Corotationalflows lie at the basis of a new, surprisingly rapid, mode of migration (type III),superseding the standard type II migration (with a gap), and revising the speed of type I migration (without a gap). The talk will contain results obtained at KITP, e.g., an analytical derivation of da/dt in type III motion. It will be illustrated by videos of high-resolution numerical simulations obtained with different implementations of the Piecewise Parabolic Method hydrodynamics.

    The paper presents standards related to ultrasound imaging of the cerebral vasculature and structures. The aim of this paper is to standardize both the performance and description of ultrasound imaging of the extracranial and intracranial cerebral arteries as well as a study of a specific brain structure, i.e. substantia nigra hyperechogenicity. The following aspects are included in the description of standards for each ultrasonographic method: equipment requirements, patient preparation, study technique and documentation as well as the required elements of ultrasound description. Practical criteria for the diagnosis of certain pathologies in accordance with the latest literature were also presented. Furthermore, additional comments were included in some of the sections. Part I discusses standards for the performance, documentation and description of different ultrasound methods (Duplex, Doppler). Part II and III are devoted to standards for specific clinical situations (vasospasm, monitoring after the acute stage of stroke, detection of a right-to-left shunts, confirmation of the arrest of the cerebral circulation, an assessment
