The objective of this study was to study the significance of tumor necrosis documented at the time of interval surgical debulking after neoadjuvant chemotherapy. Retrospective chart reviews were carried out from 1997 to 2005 to identify ovarian cancer patients treated with neoadjuvant chemotherapy. Patients' demographics together with disease characteristics, treatment-related variables, and outcomes were recorded. Cox proportional hazard models were built to model time to progression using predictor variables such as age, cancer stage, tumor grade, residual disease, percentage change in CA125 level from baseline, and degree of necrosis in resected tumor specimens. One hundred one patients were included in the study. Optimal debulking was achieved in 74% of the patients. Cox regressions revealed three significant predictive variables of time to first progression: younger age (hazard ratio [HR] = 0.95, 95% CI 0.92–0.98, P = 0.004), residual disease (P = 0.048), and the absence/minimal tumor necrosis after three cycles of neoadjuvant chemotherapy (HR = 1.97, 95% CI 1.01–3.87, P = 0.048). The estimated median survival was 50.66 months (95% CI 46.12–55.20). The lack of or minimal tumor necrosis after neoadjuvant chemotherapy is an independent risk factor for recurrent disease.

The aim of this study is to evaluate the effects on survival outcomes of the disease burden before interval debulking surgery (IDS), surgical complexity, and residual disease after IDS in advanced-stage ovarian cancer treated with neoadjuvant chemotherapy (NAC). We reviewed the data of 268 epithelial ovarian cancer patients who had received three or four cycles of NAC and undergone optimal resections through IDS. The Kaplan–Meier method and Cox regression analysis were used to assess the effects of disease burden (peritoneal cancer index (PCI)), degree of complexity of surgery (surgical complexity score/s (SCS)), and extent of residual disease. In no residual disease (R0) patients, those with intermediate/high SCS had shorter progression-free survival (PFS; p = 0.001) and overall survival (OS; p = 0.001) than patients with low SCS. An analysis of a subset of patients with R0 and low PCIs showed those with intermediate/high SCS had worse PFS and OS than patients with low SCS (p = 0.049) and OS (p = 0.037). In multivariate analysis, patients with R0 as a result of intermediate/high SCS fared worse than patients whose R0 was achieved by low SCS (PFS hazard ratio (HR) 1.80, 95% CI 1.05–3.10; OS HR 5.59, 95% CI 1.70–18.39). High PCIs at the time of IDS, high SCS, and residual disease signal poor prognoses for patients treated with NAC.

Primary Debulking Surgery

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.

ObjectiveThis study aimed to survey all practicing certified gynecological oncologists (CGOs) in Australia and New Zealand to determine their current surgical practice for primary advanced epithelial ovarian cancer (EOC) and compare the findings with an identical survey conducted 10 years previously.Methods/MaterialsA questionnaire was e-mailed to all 53 practicing CGOs in Australia and New Zealand in July 2017 assessing their definition of optimal debulking for EOC, their use of neoadjuvant chemotherapy, and the surgical procedures they use to achieve cytoreduction. Results were compared with an identical study performed in 2007 using χ2 and logistic regression analysis.ResultsResponse rate was 89% (47/53). A higher percentage of patients received neoadjuvant chemotherapy before surgery in 2017 than in 2007 (43% vs 16%, respectively). In 2017, CGOs were more likely to define optimal debulking as zero residual disease (R0; 21/44 [48%] vs 6/34 [18%], P < 0.001). To achieve this, CGOs were significantly more likely to independently perform stripping/resection of the diaphragm (44/47 [94%] vs 15/34 [44%], P < 0.001) and, with assistance from surgical colleagues, perform resection of upper para-aortic lymph nodes (39/46 [85%] vs 21/34 [62%], P = 0.02) and parenchymal liver metastases (30/46 [65%] vs 13/34 [38%], P = 0.02). They were now less likely to resect/reimplant the ureter without assistance (23% vs 53%, P = 0.01). A surgeon's definition of optimal debulking as R0 was significantly associated with a high use of neoadjuvant chemotherapy (in ≥50% of patients).ConclusionsCertified gynecological oncologists' definition of optimal debulking for primary EOC is more likely to be R0 in 2017 than in 2007. Radical abdominal surgery was performed more often in 2017, requiring assistance by a surgical colleague in many cases. An increased use of neoadjuvant chemotherapy was the only factor significantly associated with CGOs' definition of optimal debulking as R0.

Interval Cytoreduction

ObjectiveInterval cytoreduction following neoadjuvant chemotherapy is a well-recognized treatment alternative to primary debulking surgery in the treatment of advanced epithelial ovarian cancer where patient and/or disease factors prevent complete macroscopic disease resection to be achieved. More recently, the strain of the global COVID-19 pandemic on hospital resources has forced many units to alter the timing of interval surgery and extend the number of neoadjuvant chemotherapy cycles. In order to support this paradigm shift and provide more accurate counseling during these unprecedented times, we investigated the survival outcomes in advanced epithelial ovarian cancer patients with the intent of maximal cytoreduction following neoadjuvant chemotherapy with respect to timing of surgery and degree of cytoreduction.MethodsA retrospective review of all patients aged 18 years and above with FIGO (2014) stage III/IV epithelial ovarian cancer treated with neoadjuvant chemotherapy and the intention of interval cytoreduction surgery between January 2008 and December 2017 was conducted. Overall and progression-free survival outcomes were analyzed and compared with patients who only received chemotherapy. Outcome measures were correlated with the number of neoadjuvant chemotherapy cycles and amount of residual disease following surgery.ResultsSix hundred and seventy-one patients (median age 67 (range 20–91) years) were included in the study with 572 patients treated with neoadjuvant chemotherapy and surgery and 99 patients with chemotherapy only. There was no difference in the proportion of patients in whom complete cytoreduction was achieved based on number of cycles of neoadjuvant chemotherapy (2–4 cycles: 67.7%, n=337/498); ≥5 cycles: 62.2%, n=46/74). Patients undergoing cytoreduction surgery after neoadjuvant chemotherapy had a median 5-year progression-free and overall survival of 24 and 38 months, respectively. No significant difference in overall survival between surgical groups was observed (interval cytoreduction: 41 months vs delayed cytoreduction: 43 months, p=0.52). Those who achieved complete cytoreduction to R0 (no macroscopic disease) had a significant median overall survival advantage compared with those with any macroscopic residual disease (R0: 49–51 months vs R<1: 22–39 months, p<0.001 vs R≥1: 23–26 months, p<0.001).ConclusionsSurvival outcomes do not appear to be worse for patients treated with neoadjuvant chemotherapy if cytoreduction surgery is delayed beyond three cycles. In advanced epithelial ovarian cancer patients the imperative to achieve complete surgical cytoreduction remains gold standard, irrespective of surgical timing, for best survival benefit.
