Abstract Background Whether neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS) against primary debulking surgery (PDS) has a differential effect on prognosis due to Breast Cancer Susceptibility Genes (BRCA)1/2 mutations has not been confirmed by current studies. Methods All patients included in this retrospective study were admitted to Qilu Hospital of Shandong University between January 2009 and June 2020, and germline BRCA1/2 mutation were tested. Patients in stage IIIB, IIIC, and IV, re-staged by International Federation of Gynecology and Obstetrics (FIGO) 2014, were selected for analysis. All patients with NAC received 1–3 cycles of platinum-containing (carboplatin, cisplatin, or nedaplatin) chemotherapy. Patients who received maintenance therapy after chemotherapy were not eligible for this study. All relevant medical records were collected. Results A total of 308 patients were enrolled in the study, including 108 patients with BRCA1/2 mutations (BRCAmut), and 200 patients with BRCA1/2 wild-type (BRCAwt). In the two groups, 36 BRCAmut patients (33.3%) and 59 BRCAwt patients (29.5%) received neoadjuvant chemotherapy. The progression-free survival (PFS) of BRCAmut patients was significantly reduced after NAC (median: 15.0 vs. 19.0 months, HR = 0.59; p = 0.03); however, there was no statistical difference in overall survival (OS) (median: 75.1 vs. 68.5 months, HR = 0.90; p = 0.72). Whether BRCAwt patients received NAC had no significant effect on PFS (median: 13.5 vs. 14.6 months, HR = 1.02; p = 0.90) or OS (median: 54.0 vs. 56.4 months, HR = 1.23; p = 0.34). Multivariate analyses showed that the independent predictors of prolonged survival were PDS (p = 0.003), the absence of residual tumor after surgery (p = 0.010), and FIGO III stage (p = 0.011). Conclusions For advanced-stage ovarian cancer patients treated with NAC followed by IDS, PFS and OS were not significantly affected in BRCAwt patients. In BRCAmut patients, NAC-IDS resulted in a shortened PFS, but had no further effect on overall survival.

Patients in stage IIIB, IIIC, and IV, re-staged by International Federation of Gynecology and Obstetrics (FIGO) 2014, were selected for analysis. All patients with NAC received 1-5 cycles of platinum-containing (carboplatin, cisplatin, or nedaplatin) chemotherapy. Patients who received maintenance therapy after chemotherapy were not eligible for this study. All relevant medical records were collected.ResultsA total of 322 patients were enrolled, including 112 patients with BRCA1/2 mutations (BRCAmut), and 210 patients with BRCA1/2 wild-type (BRCAwt). In the two groups, 40 BRCAmut patients (35.7%) and 69 BRCAwt patients (32.9%) received NAC. The progression-free survival (PFS) of BRCAmut patients was significantly reduced after NAC (median: 14.9 vs. 18.5 months; p=0.023); however, there was no difference in overall survival (OS) (median: 75.1 vs. 72.8 months; p=0.798). Whether BRCAwt patients received NAC had no significant effect on PFS (median: 13.5 vs. 16.0 months; p=0.780) or OS (median: 54.0 vs. 56.4 months; p=0.323). Multivariate analyses in BRCAmut patients showed that the predictors of prolonged PFS were PDS (p=0.001), the absence of residual lesions (p=0.012), and FIGO III stage (p=0.020); Besides, PARP inhibitor was the independent predictor for prolonged OS in BRCAmut patients (p=0.000), for BRCAwt patients, the absence of residual lesions (p=0.041) and history of PARP inhibitors (p=0.000) were beneficial factors for OS prolongation.ConclusionsFor ovarian cancer patients with FIGO IIIB, IIIC, and IV, NAC-IDS did not adversely affect survival outcomes due to different BRCA1/2 germline mutational status.

ObjectiveThe management of women with advanced-stage serous ovarian cancer includes a combination of surgery and chemotherapy. The choice of treatment with primary debulking surgery or neoadjuvant chemotherapy varies by institution. The objective of this study was to report 5-year survival outcomes for ovarian cancer patients treated at a single institution with primary debulking surgery or neoadjuvant chemotherapy.MethodsThis study included a retrospective chart review of 303 patients with stage IIIC or IV serous ovarian carcinoma diagnosed in Calgary, Canada. The patients were categorized into 1 of the 2 treatment arms: primary debulking surgery or neoadjuvant chemotherapy. The 5-year ovarian cancer–specific survival rates were estimated using Kaplan-Meier curves.ResultsAmong the 303 eligible patients, 142 patients (47%) underwent primary debulking surgery, and 161 patients (53%) were treated with neoadjuvant chemotherapy. Five-year survival was better for patients undergoing primary debulking surgery (39%) than for patients who received neoadjuvant chemotherapy (27%; P = 0.02). Women with no residual disease experienced better overall survival than those with any residual disease (47% vs. 26%, respectively; P = 0.0002). This difference was significant for those who had primary debulking surgery (P = 0.0004) but not for the patients who received neoadjuvant chemotherapy (P = 0.09). Women who received intraperitoneal chemotherapy had better overall survival as compared with patients who received intravenous chemotherapy (44% vs 30%, respectively; P = 0.002).ConclusionsOur findings suggest that among women with no residual disease, survival is better among those who undergo primary debulking surgery than treatment with neoadjuvant chemotherapy. The latter should be reserved for women who are deemed not to be candidates for primary debulking surgery.

5540 Background: Primary debulking surgery (PDS) has been considered the standard of treatment in advanced ovarian cancer, while neoadjuvant chemotherapy, three cycles followed by interval debulking (ID) surgery, is a valid treatment alternative for patients with non-resectable disease. This study aimed to show the efficacy and safety of six cycles of neoadjuvant chemotherapy (N-CT) followed by cytoreduction, a single institution experience. Methods: Aretrospective analysis was performed of all patients (pts) with advanced ovarian cancer treated with platinum based N-CT, between January/2004 and February/2012. Results: 97 pts underwent N-CT in our institution; 78.1% and 18.8% the patients had extensive stage IIIC or IV disease at diagnosis, respectively. Median age 60 years (36 – 82). Histologic types: serous 84.5%, adenocarcinoma not specified 11.3%, endometrioide 1.0%. A median of six cycles of chemotherapy were performed. Patients did not received chemotherapy after debulking surgery. During the treatment 31.4% had grade 3/4 toxicity, the most commonly observed toxicities were hematologic toxicities and nausea, four (4.1%) patients died during chemotherapy due to disease progression. After N-CT 24.7% achieved clinical complete response, 57.7% partial response and 12.4% disease progression. From this cohort 63.1% underwent a complete resection of all macroscopic and microscopic disease (R0). Median length of hospital stay and postoperative ICU stay was 5 and 0.8 days respectively, surgical complications were not common however five (7.1%) patients needed second surgery due to operatory complications and 19 pts (27.1%) needed blood transfusion after debulking. With a median follow up of 21.8 months (0.5-139.7), median overall survival and chemotherapy-free interval were 57,7 and 9,5 months, respectively. Conclusions: Six cycles of neoadjuvant carboplatin and paclitaxel is safe, effective and does not increase perioperative and postoperative complications for patients with stage IIIC-IV not candidates for optimal/R0 PDS. The overall survival of this cohort is higher than those treated with interval debulking surgery.

ObjectiveThe objective of this retrospective study was to assess the clinical outcome of patients with advanced epithelial ovarian cancer in complete response after primary debulking surgery (PDS) or neoadjuvant chemotherapy followed by interval debulking surgery (IDS]).MethodsThe authors reviewed the hospital records of 384 patients who underwent PDS (n = 322) or IDS (n = 62) and who were in complete response after primary treatment.ResultsOptimal (residual disease [RD] < 1 cm) and complete (no gross RD) cytoreduction rates were higher after IDS than after PDS (71.0% vs 55.9%;P= 0.001 and 51.6% vs 35.7%, respectively;P= 0.02). Tumor recurred in 73.0% of the 322 complete responders after PDS versus 87.1% of the 62 complete responders after IDS (P= 0.01). The IDS group showed a higher recurrence rate within 6 months (11.3% vs 3.1%:P= 0.01) and a trend to higher recurrence rate between 6 and 12 months (30.6% vs 19.9%). Tumor recurred in 57.4% of the 115 completely cytoreduced patients after PDS versus 87.5% of the 32 completely cytoreduced patients after IDS (P= 0.001). The IDS group showed a trend to higher recurrence rate within 6 months (6.2% vs 1.7%) and a higher recurrence rate between 6 and 12 months (37.5% vs 15.6%;P= 0.01). Two-year, 5-year, and 7-year progression-free survival were 65.8%, 40.8%, and 39.3% for completely cytoreduced patients after PDS versus 43.8%, 12.5%, and 12.5% for completely cytoreduced patients after IDS (P= 0.001); and 2-year, 5-year, and 7-year overall survival were 96.4%, 69.3%, and 50.4% for the former versus 87.1%, 41.8%, and 32.6% for the latter (P= 0.001).ConclusionsThe clinical outcome of completely cytoreduced patients was significantly better for PDS group than for IDS group, and therefore, the achievement of no gross RD after surgery seemed to have a different prognostic relevance for the 2 groups.

ObjectiveNeoadjuvant chemotherapy followed by interval debulking surgery is an alternative for the management of advanced ovarian cancer (AOC). Owing to unresectable disease at initial evaluation, some patients received bevacizumab in addition to neoadjuvant chemotherapy. The aim of this study was to evaluate the safety and postoperative course of patients who had received bevacizumab before debulking surgery for AOC.MethodsIn 2012, we identified all patients with AOC who had received neoadjuvant bevacizumab before debulking surgery. We recorded patients’ characteristics, surgical course, and postoperative complications.ResultsFive patients were identified, of whom 80% were International Federation of Gynecology and Obstetrics stage 4 at diagnosis. All patients underwent surgery after 6 courses of neoadjuvant chemotherapy with carboplatin, paclitaxel, and bevacizumab. The median number of bevacizumab injections was 3 (3–4), and the median time between the last injection of bevacizumab and surgery was 54 days (34–110 days). One patient had a grade 3 complication (lymphocyst with puncture under computed tomographic scans).ConclusionIn this preliminary study, debulking surgery after neoadjuvant chemotherapy that included bevacizumab did not increase the rate of postoperative complications when there was a reasonable interval between the last bevacizumab injection and surgery. Larger studies are warranted to assess surgical safety after antiangiogenic treatment in the neoadjuvant setting for advanced ovarian cancer.
