Introduction Retroperitoneal sarcoma is a surgically managed condition that can recur locally following macroscopically complete resection. Owing to the low incidence of the condition, advances in treatment are reported infrequently but complete compartmental resection and adjuvant or neoadjuvant radiotherapy are areas under investigation. Given the practical difficulty of randomised trials, observational data can highlight advantages from progressive treatment approaches. Methods A retrospective database of consecutive retroperitoneal sarcoma resections performed at a single referral centre between March 1997 and March 2013 was interrogated. Histological, radiological and clinical data were collected. Univariate and multivariate analyses for disease free and overall survival were performed to establish independent predictors of disease recurrence and patient survival. Results A total of 79 patients underwent 90 resections (63 primary). The mean five-year overall and disease free survival rates were 55.3% and 24.8% respectively. Higher patient age, high tumour grade, presence of extraretroperitoneal disease and invasive tumour phenotype were found to significantly predict survival following multivariate analysis. Half (50%) of the tumours displayed invasive behaviour on histopathology and 42% of locoregional recurrence was intraperitoneal. Conclusions Retroperitoneal sarcoma is commonly an infiltrative tumour and often recurs outside of the retroperitoneum. These features limit the therapeutic impact of interventions that focus on gaining local control such as complete compartmental resection and radiotherapy. It seems likely that future advances in the management of this cancer will involve new systemic agents to treat this frequently systemic disease.

Objective. The goal of the study was to analyse the results of 85 cases of second-look laparotomy (SLL) and explore the influence of this procedure on survival. Patients and Methods. We reviewed retrospectively 85 cases of SLL collected and treated in our institute between 1994 and 2003. Results. Complete pathologic response (CPR) was 25.8%, microscopic disease (Rmicro) was 38.8%, and macroscopic disease (Rmacro) was 35.4%. In patients with negative SLL results, disease recurrence was diagnosed in 41%. The 3- and 5-year overall survival rates for the entire population were 91% and 87%, respectively. The 3- and 5-year disease-free survivals were, respectively, 76.3% and 58.5% in negative SLL versus 55.7% and 16% in positive SLL. The difference between the group of patients with complete response (76%) and the patients with residual microscopic disease (72%) was not significant. The tumoral residuum after initial surgery was the only prognostic factor influencing significantly the disease-free survival. On Cox regression model analysis, only initial tumoral residuum () and tumoral residuum after SLL () were independent prognostic factors for survival. Conclusions. The most important advantage of SLL is the early detection of recurrence and thus the early administration of consolidation treatment resulting in a better prognosis.

Abstract Recurrent ependymomas have a dismal prognosis (2 year survival rates 29% OS and 23% EFS) and are relatively resistant to conventional chemotherapy. We previously reported five relapsed ependymoma patients treated with a MEMMAT based metronomic antiangiogenic combination therapy. All patients are currently alive, including four patients who were multiply relapsed with at least three recurrences. These four patients received between 44–52 weeks of therapy with minimal toxicity. Three had recurrent disease within an average of 44 months (median 42 months) after discontinuation of therapy. One patient who received the following tapering bevacizumab schedule: q3 weeks x 3, q4 weeks x 4 and q5 weeks x 5 followed by maintenance therapy with fenofibrate and celecoxib is in complete remission 12 months post treatment. This regimen was well tolerated with good quality of life in this patient population. Our results suggest that the chosen anti-angiogenic drug combination prolonged the time to progression in these multiply relapsed patients and thus may be particularly beneficial for patients with recurrent ependymoma. Tapered bevacizumab and maintenance therapy with celecoxib and fenofibrate may be modifications worth further investigation for prolonged disease free survival in relapsed ependymoma patients.

PURPOSE: To determine the toxicity and recommended phase II doses of the combination of fludarabine plus cyclophosphamide in chemotherapy-naive patients with low-grade lymphoma. PATIENTS AND METHODS: Previously untreated patients with low-grade lymphoma were entered onto dosing cohorts of four patients each. The cyclophosphamide dose, given on day 1, was increased from 600 to 1,000 mg/m2. Fludarabine 20 mg/m2 was administered on days 1 through 5. The first eight patients were treated every 21 days; later patients were treated every 28 days. Prophylactic antibiotics were required. RESULTS: Prolonged cytopenia and pulmonary toxicity each occurred in three of eight patients treated every 3 weeks. The 19 patients treated every 28 days, who were given granulocyte colony-stimulating factor as indicated, did not have undue nonhematologic toxicity. Dose-limiting toxicity was hematologic. At the recommended phase II/III dose (cyclophosphamide 1,000 mg/m2), grade 4 neutropenia was observed in 17% of all cycles and 31% of first cycles. Grade 3 or 4 thrombocytopenia was seen in only 1% of all cycles. The median number of cycles per patient was six (range, two to 11) for all patients enrolled. The response rate was 100% of 27 patients entered; 89% achieved a complete and 11% a partial response. Nineteen of 22 patients with bone marrow involvement had clearing of the marrow. Median duration of follow-up was more than 5 years; median overall and disease-free survival times have not been reached. Kaplan-Meier estimated 5-year overall survival and disease-free survival rates were 66% and 53%, respectively. CONCLUSION: The recommended dosing for this combination in patients with previously untreated low-grade lymphoma is cyclophosphamide 1,000 mg/m2 day 1 and fludarabine 20 mg/m2 days 1 through 5. The regimen has a high level of activity, with prolonged complete remissions providing 5-year overall and disease-free survival rates as high as those reported for other therapeutic approaches in untreated patients.

Abstract Introduction BRAF V600E is one of the most common mutations in Papillary Thyroid Cancer (PTC). Its clinical correlation has been extensively studied with contradictory results. The aim of this study is to evaluate the oncological impact of BRAF V600E mutation on a cohort of Middle Eastern PTC patients treated at a single institute.Methods Patients with histologically confirmed PTC that were treated surgically between 2006 to 2015 were included in the study. Formalin fixed paraffin embedded tumor blocks were sectioned and tested for BRAF V600E mutation. Short- and long-term oncological outcomes were collected. Results 128 patients (68% females) were included with a mean age of 38 years (±13.8). Median follow-up was 50 months. BRAF V600E mutation was found in 71% of patientsIThe BRAF negative tumors were significantly larger than the BRAF positive (3.47 cm versus 2.31 cm respectively, P = 0.009). All other clinicopathological characteristics were comparable between BRAF V600E mutation positive and negative groups. The two groups showed similar 5-year Disease-free (P= 0.37) and Overall survival rates (P = 0.94).Conclusion BRAF V600E mutation did not affect loco-reginal recurrence, distant metastasis, overall and disease-free survival. These results support the diversity of BRAF V600E significance among various ethnicities.

Prevention Of Breast Cancer

PURPOSE The mechanisms of antitumor activity, clinical pharmacology, toxicity, and efficacy of tamoxifen in women with early and advanced breast cancer and the drug's potential role in prevention of breast cancer were reviewed. DESIGN A comprehensive review of the literature from 1966 to 1994 was conducted; reports were identified using the Cancerline and Medline data bases. RESULTS The cellular actions of tamoxifen are not completely understood, but it appears that the drug's antiproliferative effects are mediated primarily by inhibition of the activities of estrogen through binding to estrogen receptors (ERs). Disease-free and overall survival rates have been increased in postmenopausal women with ER-positive tumors when tamoxifen has been used as adjuvant therapy (irrespective of nodal status). In premenopausal women, adjuvant therapy with tamoxifen has been associated with prolongation of disease-free survival, but its impact on survival remains to be defined. Tamoxifen is the initial hormonal treatment of choice in both premenopausal and postmenopausal women with ER-positive metastatic disease. Retrospective review of adjuvant therapy studies showed an approximately 39% reduction in the incidence of contralateral primary breast carcinoma in tamoxifen-treated women, which indicates that tamoxifen could have a role in breast cancer prevention. CONCLUSION The use of tamoxifen has resulted in a substantial modification of breast cancer's natural history, particularly in postmenopausal women. Ongoing clinical trials will examine the effects of tamoxifen therapy on lipids, coagulation proteins, bone, and endometrium, and its effectiveness as an agent in the prevention of breast cancer.

246 Background: Among patients with potentially curable esophageal cancer (EC) or gastroesophageal junctional cancer (GEJC) treated with curative intent, survival remains poor and around half of these patients have disease recurrence within a few years. This study addresses the need for real-world data on disease-free survival (DFS) and overall survival (OS) in patients with EC or GEJC who underwent potentially curative treatment. Methods: Patients selected from the nationwide Netherlands cancer registry (NCR) had received a primary diagnosis of non-metastatic EC or GEJC (excluding patients with T4b tumors) in 2015 or 2016 and received treatment with curative intent. Curative intent was defined as receiving resection (with or without [neo]adjuvant therapy) or definitive chemoradiotherapy (dCRT) without surgery. DFS and OS were analysed using Kaplan-Meier curves with Log-Rank test from resection date or end of dCRT. A sub-analysis was performed for NCR patients selected to align with the population of the CheckMate-577 phase 3 study of adjuvant nivolumab, i.e. patients with non-cervical stage II/III disease, R0 resection and residual pathological disease after neoadjuvant CRT (nCRT) and surgery. Results: We identified 1916 patients of median age of 67 years and predominantly male (76%). The majority (79%) received surgery and 21% of patients received dCRT. In resected patients, 83% received nCRT, 10% neoadjuvant chemotherapy (with or without adjuvant CRT) and 7% received no (neo)adjuvant treatment. Compared to the resected group, the population receiving dCRT had significantly fewer males (65% vs 78%), a higher median age (72 vs 65 years) and worse performance status. Patients receiving dCRT significantly shorter median DFS (14.2 months) and OS (20.9 months) compared to resected patients (DFS: 26.4 months, p < 0.001; OS: 40.5 months, p < 0.001). The 1- and 3-year DFS probabilities were 68% and 44%, respectively, in resected patients, and 56% and 24%, respectively, in patients receiving dCRT. In patients receiving nCRT followed by surgery, the median DFS and OS were 25.2 and 38.0 months, respectively, and 1- and 3-year DFS probabilities were 67% and 43%, respectively. In the sub-analysis (n = 725) the median DFS and OS were 19.2 and 29.4 months, respectively, and the 1- and 3-year DFS rates were 62% and 36%, respectively. Conclusions: Although patients are treated with curative intent, a considerable amount of patients with non-metastatic EC or GEJC experienced recurrence within two years. Resected patients had a higher DFS and OS compared to patients receiving dCRT.

Analysis of a series of 137 women 20–30 years of age, operated for breast carcinoma, excluding patients pregnant, lactating or with inflammatory cancer, showed that disease-free survival rates were similar and not lower than those reported for a large series of 716 breast cancer patients of all ages, treated and followed at the same Institute. Ten-year disease-free survival rates for the two series of 137 young women and 716 patients of all ages were 43.7% and 47.1% respectively. Even when considering the subgroups of patients with and without nodal axillary involvement, the corresponding figures for the two series considered were 72.6% vs. 72.1% (N−) and 25.1% vs. 24.5% (N+). It can be concluded that young age cannot be considered as an unfavorable prognostic factor.

AbstractObjective:To evaluate the clinical and histopathological factors affecting the prognosis of patients with squamous cell locoregional advanced laryngeal cancer.Methods:A retrospective chart review was conducted of 121 patients with locoregional advanced laryngeal cancer, primarily treated with surgery from 2007 to 2011. Disease-free survival and overall survival rates were analysed as oncological outcomes. Prognostic variables, namely gender, pharyngeal invasion, pathological assessment of tumour and nodal stage, adjuvant therapy, margin status, nodal extracapsular extension, tumour differentiation, lymphovascular and perineural invasion, and predominant growth pattern, were also analysed.Results:One-year and three-year disease-free survival rates were 81.3 per cent and 63.5 per cent, respectively. One-year and three-year overall survival rates were 88.3 per cent and 61.4 per cent, respectively. Multivariate analysis showed that nodal extracapsular extension (p < 0.05) and an infiltrative growth pattern (p < 0.05) were associated with disease progression. Nodal extracapsular extension (p < 0.05) was associated with higher mortality.Conclusion:Nodal extracapsular extension and an infiltrative growth pattern were the main prognostic factors in locoregional advanced laryngeal cancer. The presence of pharyngeal invasion, pathologically confirmed node-positive stage 2–3 disease, close or microscopic positive margins, and lymphovascular and perineural invasion have a negative impact on prognosis.
