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 Background A prognostic benefit of additive chemotherapy in patients following resection of metachronous colorectal liver metastases (CRLM) remains controversial. Therefore, the goal of this retrospective study was to investigate the impact of perioperative chemotherapy on disease-free survival (DFS) and overall survival (OS) of patients after curative resection of metachronous CRLM. Methods In a retrospective single-centre study, patients after curative resection of metachronous CRLM were included and analysed for DFS and OS with regard to the administration of additive chemotherapy. The Kaplan-Meier method was applied to compare DFS and OS while Cox regression models were used to identify independent prognostic variables. Results Thirty-four of 75 patients were treated with additive 5-FU based chemotherapy. OS was significantly prolonged in this patient subgroup (62 vs 57 months; p = 0.032). Additive chemotherapy significantly improved 10-year survival rates (42% vs 0%, p = 0.023), but not 5-year survival (58% vs 42%, p = 0.24). Multivariate analysis identified additive chemotherapy (p = 0.016, HR 0.44, 95% CI 0.23–0.86), more than five CRLM (p = 0.026, HR 2.46, 95% CI 1.16–10.32) and disease recurrence (0.009, HR 2.70, 95% CI 1.29–5.65) as independent risk factors for OS. Conclusion Additive chemotherapy significantly prolonged OS and 10-year survival in patients after curative resection of metachronous CRLM. Randomized clinical trials are needed in the future to identify optimal chemotherapy regimens for those patients.

5540 Objectives: To determine the efficacy, disease free and overall survivals of radiation therapy in combination with four non-platinum chemotherapy regimens for locally advanced cervical cancer. Materials and Methods: Eligible patients were those with a diagnosis of locally advanced cervical cancer, under 70 years of age, and undergone the necessary prestudy investigations. All patients received external-beam pelvic irradiation to a minimum dose of 5,000 cGy, and brachytherapy delivered to bring the minimum total dose at point A to 7,500 cGy. Patients were randomized to receive one of four chemotherapy regimens: Arm1: oral 5FU 250 mg/m2/day, Arm2: mitomycin 12 mg/m2 on days 1 and 28 + oral 5FU 200 mg/m2/day, Arm3: mitomycin 12 mg/m2 on days 1 and 28 followed by 5FU 1,000 mg/m2/day on days 1 through 4 and 28 through 31, Arm4: oral hydroxyurea 25 mg/kg/day. Results: From September 1995 to October 2001, the study include 921 women; 226 in arm 1, 229 in arm 2, 234 in arm 3, and 232 in arm 4. The median follow-up time was 51.69 months. More than 89% of the patients achieved complete response. Disease free survival rates were 62.4% among arm 1, 63.8% among arm 2, 66.2% among arm 3, and 68.5% among arm 4. Overall survival rates were 77.4%, 79.5%, 80.8%, and 84.5% respectively. Conclusion: The efficacy of these regimens were not inferior to the standard platinum based regimen for locally advanced cervical cancer. This study demonstrates the results of large randomized clinical study of radiochemotherapy and requires the longer follow up time for the late complications.

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.

Recent studies suggest that long-interspersed nucleotide element-1 (LINE-1) hypomethylation is commonly found in colorectal cancer (CRC), and is associated with worse prognosis. However, the utility of LINE-1 methylation on the prognosis of CRC is still controversial, and may be due to the fact that some clinical and pathological features may affect LINE-1 methylation. Thus, the aim of this study was to assess the prognostic value of tumor LINE-1 methylation in CRC, through their association with the CRC clinical and pathological characteristics. Survival of sixty-seven CRC patients was evaluated according to the median of tumor LINE-1 methylation, as well as pathological and oncological variables. We also studied the association between LINE-1 methylation and pathological features, and finally, we assessed the overall and disease-free survival of LINE1 methylation, stratified by neoadjuvant treatment and further checked by multivariate Cox regression to assess the statistical interactions. LINE-1 was hypomethylated in the CRC tumor with respect to the tumor adjacent-free area (p < 0.05), without association with any other clinical and oncological features, nor with overall and disease-free survival rates for CRC. Relevantly, in neoadjuvant treatment, LINE-1 methylation was associated with survival rates. Thus, disease-free and overall survival rates of treated CRC patients were worse in the hypomethylated LINE-1 tumors than those with normal LINE-1 methylation (p = 0.004 and 0.0049, respectively). Indeed, LINE-1 was hypermethylated more in the treated patients than in the non-treated patients (p < 0.05). The present study showed that tumor LINE-1 hypomethylation was associated with worse survival rates in only treated patients. Our data suggest an interactive effect of neoadjuvant treatment and tumor LINE-1 methylation, which could be a specific-tissue biomarker to predict survival of the treated patients, and help to personalize treatment in CRC.

ObjectiveOptimal cytoreduction and response to chemotherapy have been associated with prolonged disease-free survival (DFS), but there are limited data regarding the clinical characteristics of those patients with optimal 5-year DFS (5YrDFS) outcomes.MethodsA case-control study was performed on 32 patients who were progression-free and alive at 5 years with advanced ovarian cancer 5YrDFS from 1993 to 2005 for this institutional review board-approved study. Matching controls were identified from the subset of patients who died or experienced disease progression before 5 years.ResultsOne hundred sixty patients were evaluated. There was no statistical difference between cases and controls in regard to neoadjuvant chemotherapy, grade, race, preoperative cancer antigen-125 level, optimal cytoreduction, operating room time, length of hospital stay, or total chemotherapy cycles in regard to 5YrDFS. If a patient achieved complete response after primary treatment, the likelihood of progression-free survival 5 years or longer is 7 times more likely, (odds ratio = 7.2 [95% confidence interval = 2.3-22.4]; P = 0.0006).ConclusionIn this matched case-control analysis, complete response after primary treatment was the only significant factor associated with 5YrDFS. Further study is needed in patient and tumor characteristics to identify those patients who may have poor or favorable outcomes before treatment completion.

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.

Objective: Microprolactinomas are currently treated with dopamine agonists. Outcome information on microprolactinoma patients treated by surgery is limited. This study reports the first large series of consecutive non-invasive microprolactinoma patients treated by pituitary surgery and evaluates the efficiency and safety of this treatment. Design: Follow-up of a cohort of consecutive patients treated by surgery. Methods: Between January 2008 and October 2020, 114 adult patients with pure microprolactinomas were operated on in a single tertiary expert neurosurgical department, using an endoscopic endonasal transsphenoidal approach. Eligible patients were presenting a microprolactinoma with no obvious cavernous invasion on MRI. Prolactin was assayed before and after surgery. Disease-free survival was modeled using Kaplan-Meier representation. A cox regression model was used to predict remission. Results: Median follow-up was 18.2 months (range: 2.8 to 155). In this cohort, 14/114 (12%) patients were not cured by surgery, including 10 early surgical failures, and 4 late relapses occurring 37.4 months (33 to 41.8) after surgery. From Kaplan Meier estimates, 1-year and 5-year disease free survival were 90.9% (95% CI, 85.6%-96.4%) and 81% (95% CI,71.2%-92.1%) respectively. The preoperative prolactinemia was the only significant preoperative predictive factor for remission (P<0.05). No severe complication was reported, with no anterior pituitary deficiency after surgery, one diabetes insipidus, and one postoperative cerebrospinal fluid leakage properly treated by muscle plasty. Conclusions: In well selected microprolactinoma patients, pituitary surgery performed by an expert neurosurgical team is a valid first-line alternative treatment to dopamine agonists.

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.
