To determine if the time-to-chemotherapy (TTC) after primary macroscopic complete cytoreductive surgery (CRS) influences recurrence-free survival (RFS) and overall survival (OS) in patients with epithelial ovarian cancer (EOC). We conducted an observational multicenter retrospective cohort analysis of women with EOC treated from September 2006 to November 2016 in nine institutions in France (FRANCOGYN research group) with maintained EOC databases. We included women with EOC (all FIGO stages) who underwent primary complete macroscopic CRS prior to platinum-based adjuvant chemotherapy. Two hundred thirty-three patients were included: 73 (31.3%) in the early-stage group (ESG) (FIGO I-II), and 160 (68.7%) in the advanced-stage group (ASG) (FIGO III-IV). Median TTC was 43 days (36–56). The median OS was 77.2 months (65.9–106.6). OS was lower in the ASG when TTC exceeded 8 weeks (70.5 vs. 59.3 months, p = 0.04). No impact on OS was found when TTC was below or above 6 weeks (78.5 and 66.8 months, respectively, p = 0.25). In the whole population, TTC had no impact on RFS or OS. None of the factors studied were associated with an increase in TTC. Chemotherapy should be initiated as soon as possible after CRS. A TTC greater than 8 weeks is associated with poorer OS in patients with advanced stage EOC.

5522^ Background: Metformin, has recently shown some anti-cancer activities in ovarian cancer, both in vitro and in vivo. Methods: Analysis of Recurrence Free Survival (RFS) and Overall Survival (OS) was performed in patients (pts) with diabetes (D) treated with metformin (DMet+) or not (DMet-) enrolled in the MIMOSA trial, a randomized double-blind placebo-controlled international trial of Abagovomab maintenance therapy in 888 pts with advanced ovarian cancer. In the MIMOSA trial, no differences in the RFS and OS were observed between Abagovomab (n = 593) and Placebo arm (n = 295); hence, the present RFS and OS analysis (DMet+ vs DMet-) was run regardless of treatment allocation. A Cox proportional hazards model was used for adjusting the analysis for the predefined prognostic factors: Figo stage (III, IV), tumor size after debulking (residual tumor <1 cm, >1cm); CA125 serum level after 3th cycle (<35U/ml, >35U/ml). In addition, comparison of RFS and OS was done between DMet+and the overall MIMOSA population not exposed to metformin (ALLMet-), and between the overall diabetic pts (ALLD+) and non-diabetic pts (ALLD-). Results: In the ALL population (n = 888), 42 pts were affected by diabetes (ALLD+) divided to DMet+ (n = 27) and DMet- (n = 15), without difference in the prognostic factors distribution. When analysis was done in ALLD+, RFS median time was not reached in the DMet+ group whereas it was 328 days [CI: 30-660] in DMet- group with HR favoring DMet+=0.419 [CI:0.175-1.002]; p = 0.05. Median OS time was also not reached in the DMet+ group whereas it was 786 days [CI:262-NE] in DMet- group with HR=0.295 [CI:0.109-0.803]; p = 0.02. Interestingly HR for RFS time was still in favour of DMet+ group when compared to the ALLMet- (n=861) with HR=0.575 (CI=0.324-1.022); p = 0.06. When ALLD+ were compared with ALLD-(n = 846), no significant differences was detected in RFS and OS time. Conclusions: The present results are the first prospectively analyzed data demonstrating a favourable impact of metformin treatment on RFS and OS in pts affected by advanced ovarian cancer.

ObjectiveSurgical management of advanced ovarian cancer often requires low modified posterior pelvic exenteration (MPE) to achieved complete resection. The aim of this study was to evaluate the morbidity of MPE at the time of primary cytoreductive surgery (PCS) and interval cytoreductive surgery (ICS) after neoadjuvant chemotherapy.Materials and MethodsFrom 2001 to 2009, 63 patients underwent MPE for advanced ovarian cancer. We analyzed and compared surgical characteristics and postoperative courses between PCS and ICS.ResultsModified posterior pelvic exenteration was performed during PCS for 50 patients (79%) and during ICS for 13 patients (21%). Complete cytoreduction was achieved in 80% of patients (84% in the PCS group and 69% in the ICS group; ns). There was no significant difference between the PCS and ICS groups in the type and the rate of standards or radical surgical procedures. Patients with ICS had a shorter length of stay in the intensive care unit (0.9 vs 2.7 days; P = 0.009), but there was no difference in the total length of hospitalization (P = 0.94). The global rate of postoperative complications was 76%. No differences were found between the 2 groups in digestive or extradigestive complications, iterative surgery, or interventional radiology procedures. The median overall survival was 49.4 months in the PCS group and 27.1 months in the ICS group (P = 0.27), and the median progression-free survival time in both groups was 20 months.ConclusionsThere was no difference in the occurrence of postoperative complications between PCS and ICS, especially in morbidity related to MPE. The specific morbidity of this surgical procedure remained low compared with the overall morbidity in cases of extensive surgery.

ObjectivesThe objective of this study was to examine the overall and recurrence-free survival in patients with advanced ovarian cancer based on hemoglobin and blood transfusions.MethodsA retrospective chart review was performed between 2003 and 2007 on patients with pathologically confirmed stage 3–4 ovarian, fallopian, or peritoneal cancers. Data were collected on date of diagnosis, recurrence and death, stage, grade, age, surgery, estimated blood loss, hemoglobin (nadir and average levels), and number of blood transfusions.ResultsTwo hundred sixteen patients were included in the final analysis. In the perichemotherapy, perioperative, and total time frames, 88%, 81%, and 95% of patients were anemic, and 9%, 22%, and 26% of the patients had severe anemia. After adjusting for age, stage, and optimal debulking status, the perichemotherapy hemoglobin level as a continuous variable was weakly associated with recurrence-free survival (adjusted hazard ratio [AHR], 0.98;P= 0.03), and as a categorical variable with both recurrence-free survival (AHR, 2.49;P= 0.003) and overall survival (AHR, 1.91;P= 0.02). The total number of transfusions was also weakly associated with poor recurrence-free survival (AHR, 1.06;P= 0.03).ConclusionsOur study is a retrospective analysis of the effects of anemia and transfusion on ovarian cancer. The rates of anemia in chemotherapy patients are higher than previously reported. Although maintaining average hemoglobin greater than 80 g/L during chemotherapy portends an improved overall survival, blood transfusion does not have any effect. The role of transfusion should therefore be limited to symptomatic patients while giving 1 unit at a time. Further prospective studies will be needed to confirm these results.

Актуальность. Для современной клинической онкологии одной из важнейших целей является развитие персонифицированного подхода в лечении онкологических пациентов. Это связано с высоким уровнем токсичности химиотерапевтических лекарственных средств. Ключевыми препаратами, использующимися в схемах химиотерапии при раке яичников, являются производные платины, сочетающие высокую эффективность и столь же высокую токсичность. Это делает актуальным поиск маркеров чувствительности к данной группе препаратов. Целью данной работы было изучение статуса полиморфных маркеров генов XRCC1, ERCC2 и CDKN1A и их связи с длительностью времени без прогрессирования (ВБП), которое является суррогатным клиническим маркером чувствительности к производным платины при раке яичника. Материалы и методы. В исследование были включены 26 больных распространенным раком яичника (II-IV стадии), у которых до начала химиотерапии, при первичной циторедуктивной операции, был произведен забор образцов опухолевой ткани. После операции все больные получили стандартную химиотерапию с использованием паклитаксела и препаратов платины. Из образцов опухолевой ткани выделяли ДНК с помощью набора Diatom DNA Prep 400 (Россия). Определение статуса полиморфных маркеров Gln399Arg гена XRCC1, Lys751Gln гена ERCC2 и Ser31Arg гена CDKN1A проводили методом ПЦР-ПДРФ и подтверждением результата методом ПЦР в реальном времени с последующим анализом кривых плавления продукта ПЦР. Статус маркеров был сопоставлен с длительностью ВБП. Результаты. Нами выявлена тенденция к большей продолжительности ВБП при наличии аллеля Gln маркера Gln399Arg гена XRCC1 (медиана ВБП составляла 14,1 мес. у больных с наличием аллеля Gln в сравнении с 10,9 мес. в подгруппе больных с отсутствием аллеля Gln, р = 0,095). В подгруппе больных, которым была проведена оптимальная циторедуктивная операция, носительство минорного аллеля Arg маркера Ser31Arg гена СDKN1A ассоциировалось с уменьшением медианы ВБП (19,1 и 12,8 мес. при отсутствии и наличии аллеля Arg соответственно, р = 0,035). Вывод. Выявлена взаимосвязь статуса полиморфных маркеров генов XRCC1 и CDKN1A с длительностью ремиссии после платиносодержащей химиотерапии рака яичника, что делает целесообразным дальнейшее изучение данных молекулярно-генетических факторов на более репрезентативной группе больных раком яичника. Background: The most important goal of current clinical oncology is personalized treatment primarily due to high toxicity of chemotherapeutic drugs. The key drugs used in chemotherapy of ovarian cancer are platinum derivatives, which are both highly effective and highly toxic. Therefore, searching for sensitivity markers for this group of drugs is very relevant. The aim of this work was to study polymorphic markers of XRCC1 and ERCC2 DNA repair genes and the cell cycle regulation gene, CDKN1A, and their relationship with progression-free survival time (PFS), which is a surrogate clinical marker for sensitivity of ovarian cancer to platinum drugs. Materials and methods. The study included 26 patients with advanced ovarian cancer (stage II-IV). Tumor samples were withdrawn from patients before the onset of chemotherapy, during the primary cytoreductive surgery. After surgery, all patients received a standard chemotherapy with paclitaxel and platinum drugs. DNA was isolated from tumor tissue samples using a Diatom DNA Prep 400 kit (Isogen, Russia). The polymorphic markers, Gln399Arg of the XRCC1 gene, Lys751Gln of the ERCC2 gene, and Ser31Arg of the CDKN1A gene were analyzed by PCR-RFLP and real-time PCR melting curves analysis as a reference. The marker status was compared with the duration of PFS. Results. A tendency towards longer duration of PFS was observed in the presence of the Gln allele of Gln399Arg XRCC1 marker (median PFS, 14.1 months in patients with the Gln allele vs. 10.9 months in the subgroup without the Gln allele; p = 0.095). In the subgroup with optimal cytoreductive surgery, carrying the minor Arg allele of the CDKN1A gene Ser31Arg marker was associated with duration of PFS. In the presence of the minor Arg allele, the PFS duration after platinum-containing chemotherapy was statistically significantly decreased (median PFS, 19.08 months in the absence of Arg allele vs. 12.82 months in the presence of Arg allele, p = 0.035). Conclusion. Polymorphic markers of XRCC1 and CDKN1A genes were found to be related with remission duration after platinum-containing chemotherapy of ovarian cancer. This suggests advisability of further studies of these molecular genetic factors on a representative group of patients with ovarian cancer.

5519 Background: Cytoreductive surgery and systemic therapy are essential for newly diagnosed ovarian cancer. We conducted a multicenter phase 3 trial to study whether the addition of intraperitoneal chemotherapy under hyperthermic conditions (HIPEC) to interval cytoreductive surgery would improve outcome among patients receiving neo-adjuvant chemotherapy for stage III epithelial ovarian cancer. Methods: We randomly assigned patients who showed at least stable disease after three cycles of carboplatin (area under the curve 6) and paclitaxel (175 mg/m2) to receive interval cytoreductive surgery with or without HIPEC using cisplatin (100 mg/m2). Randomization was performed per-operatively and eligible patients had no residual mass greater than 2.5 mm. Three additional cycles of carboplatin and paclitaxel were given post-operatively. The primary endpoint was recurrence-free survival. Overall survival, toxicity, and quality-of-life were key secondary endpoints. Results: A total of 245 patients were randomly assigned to one of the two treatment strategies. In an intention-to-treat analysis, interval cytoreductive surgery with HIPEC was associated with longer recurrence-free survival than interval cytoreductive surgery alone (15 vs. 11 months, respectively; hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.49 to 0.86; P=0.003). At the time of analysis, 49% of patients were alive, with a significant improvement in overall survival favoring HIPEC (48 vs. 34 months; HR, 0.64; 95% CI, 0.45 to 0.91, P=0.01). The number of patients with grade 3-4 adverse events was similar in both treatment arms (28% vs. 24%, p=0.61). Quality-of-life analysis will follow. Conclusions: The addition of HIPEC to interval cytoreductive surgery is well tolerated and improves recurrence free and overall survival in patients with stage III epithelial ovarian cancer.
