PurposeThe management of recurrent ovarian cancer remains controversial. Single-agent topotecan is an established treatment option, and preliminary evidence suggests improved tumor control by combining topotecan with etoposide or gemcitabine.Patients and MethodsWomen with relapsed ovarian cancer after primary surgery and platinum-based chemotherapy were randomly assigned to topotecan monotherapy 1.25 mg/m2/d, topotecan 1.0 mg/m2plus oral etoposide 50 mg/d, or topotecan 0.5 mg/m2/d plus gemcitabine 800 mg/m2on day 1 and 600 mg/m2on day 8 every 3 weeks. Patients were stratified for platinum-refractory and platinum-sensitive disease according to a recurrence-free interval of less or more than 12 months, respectively. The primary end point was overall survival. Secondary end points included progression-free survival, objective response rates, toxicity, and quality of life (as measured by the European Organisation for Research and Treatment of Cancer [EORTC] 30-item Quality-of-Life Questionnaire).ResultsThe trial enrolled 502 patients with a mean age of 60.5 years (± 10.2 years), 208 of whom were platinum resistant. Median overall survival was 17.2 months (95% CI, 13.5 to 21.9 months) with topotecan, 17.8 months (95% CI, 13.7 to 20.0 months) with topotecan plus etoposide (log-rank P = .7647), and 15.2 months (95% CI, 11.3 to 20.9 months) with topotecan plus gemcitabine (log-rank P = .2344). Platinum-sensitive patients lived significantly longer than platinum-refractory patients (21.9 v 10.6 months). The median progression-free survival was 7.0, 7.8, and 6.3 months, respectively. Objective response rates were 27.8%, 36.1%, and 31.6%, respectively. Patients under combined treatment were at higher risk of severe thrombocytopenia.ConclusionNonplatinum topotecan combinations do not provide a survival advantage over topotecan alone in women with relapsed ovarian cancer.

IntroductionThe role of cytoreductive surgery in the poly-ADP ribose polymerase inhibitors era is not fully investigated. We evaluated the impact of surgery performed prior to platinum-based chemotherapy followed by olaparib maintenance in platinum-sensitive BRCA-mutated recurrent ovarian cancer.MethodsThis retrospective study included platinum-sensitive recurrent ovarian cancer BRCA-mutated patients from 13 Multicenter Italian Trials in Ovarian cancer and gynecological malignancies centers treated between September 2015 and May 2019. The primary outcomes were progression-free survival and overall survival. Data on post-progression treatment was also assessed.ResultsAmong 209 patients, 72 patients (34.5%) underwent cytoreductive surgery followed by platinum-based chemotherapy and olaparib maintenance, while 137 patients (65.5%) underwent chemotherapy treatment alone. After a median follow-up of 37.3 months (95% CI: 33.4 to 40.8), median progression-free survival in the surgery group was not reached, compared with 11 months in patients receiving chemotherapy alone (P<0.001). Median overall survival was nearly double in patients undergoing surgery before chemotherapy (55 vs 28 months, P<0.001). Post-progression therapy was assessed in 127 patients: response rate to chemotherapy was 29.2%, 8.8%, and 9.0% in patients with platinum-free interval >12 months, between 6 and 12 months, and <6 months, respectively.ConclusionCytoreductive surgery performed before platinum therapy and olaparib maintenance was associated with longer progression-free survival and overall survival in BRCA-mutated platinum-sensitive relapsed ovarian cancer patients. In accordance with our preliminary results, the response rate to chemotherapy given after progression during olaparib was associated with platinum-free interval.

Purpose Most patients with advanced ovarian cancer develop recurrent disease. For those patients who recur at least 6 months after initial therapy, paclitaxel platinum has shown a modest survival advantage over platinum without paclitaxel; however, many patients develop clinically relevant neurotoxicity, frequently resulting in treatment discontinuation. Thus, an alternative regimen without significant neurotoxicity was evaluated by comparing gemcitabine plus carboplatin with single-agent carboplatin in platinum-sensitive recurrent ovarian cancer patients. Methods Patients with platinum-sensitive recurrent ovarian cancer were randomly assigned to receive either gemcitabine plus carboplatin or carboplatin alone, every 21 days. The primary objective was to compare progression-free survival (PFS). Results Three hundred fifty-six patients (178 gemcitabine plus carboplatin; 178 carboplatin) were randomly assigned. Patients received a median of six cycles in both arms. With a median follow-up of 17 months, median PFS was 8.6 months (95% CI, 7.9 to 9.7 months) for gemcitabine plus carboplatin and 5.8 months (95% CI, 5.2 to 7.1 months) for carboplatin. The hazard ration (HR) for PFS was 0.72 (95% CI, 0.58 to 0.90; P = .0031). Response rate was 47.2% (95% CI, 39.9% to 54.5%) for gemcitabine plus carboplatin and 30.9% (95% CI, 24.1% to 37.7%) for carboplatin (P = .0016). The HR for overall survival was 0.96 (95% CI, 0.75 to1.23; P = .7349). While myelosuppression was significantly more common in the combination, sequelae such as febrile neutropenia or infections were uncommon. No statistically significant differences in quality of life scores between arms were noted. Conclusion Gemcitabine plus carboplatin significantly improves PFS and response rate without worsening quality of life for patients with platinum-sensitive recurrent ovarian cancer.

Background: Olaparib maintenance therapy has shown efficacy and tolerability in patients with platinum-sensitive, high-grade serous recurrent ovarian cancer (HSROC) with BRCA1/2 mutation (BRCAm). Our aim was to present real-world experience with olaparib in Korea. Method: We included HSROC patients with BRCAm treated with olaparib maintenance at four institutions in Korea between 2016 and 2018. Medical records were reviewed for clinico-pathologic characteristics, objective response, survival outcomes, and safety. Results: One hundred HSROC patients with BRCAm were included. BRCA1 mutation was present in 71 patients (71.0%), and BRCA2 mutation was present in 23 patients (23.0%). In terms of the best objective response with olaparib maintenance in 53 patients with partial remission from most recent chemotherapy, complete remission occurred in 12 (22.6%) and partial remission in four (7.5%), while 33 patients (62.3%) had stable disease. The 24 month progression-free survival was 42.4%, and 24 month overall survival was 82.1%. Grade 3 or more adverse events were as follows: anemia in 14 patients (14.0%), neutropenia in seven patients (7.0%), thrombocytopenia in two patients (2.0%), oral mucositis in one patient (1.0%), and soft tissue infection in one patient (1.0%). Conclusions: The safety and effectiveness of olaparib maintenance treatment in a real-world study were consistent with those reported in previous clinical trials.

ObjectiveThe optimal role of bevacizumab (Bev) in the treatment of ovarian cancer has not yet been established. Furthermore, it is unclear whether there is a benefit of Bev after progression on a Bev-containing regimen in ovarian cancer. The objective of this study was to compare response rates, progression-free survival (PFS), and overall survival between patients who were treated with chemotherapy and Bev after progression on Bev (BAB) versus patients who were treated with chemotherapy without Bev (CWOB).MethodsWe conducted a retrospective chart review of all patients who received treatment with Bev (with or without cytotoxic chemotherapy) for recurrent ovarian cancer at a single institution. Patients who received additional therapy after progression while on Bev were included.ResultsForty-six patients were included (16 CWOB group and 30 BAB). The median number of previous chemotherapy regimens was 2.5 for CWOB compared with 4 for BAB (P= 0.11). Fifty-two percent of patients had an objective response to the first Bev regimen before progressing on Bev. Response rates for the regimen after progression on Bev were 19% (3/16) in the CWOB group and 23% (7/30) in the BAB group (P= 1). Twenty-five percent of the patients who responded to the first Bev regimen and 18% of those who did not respond to the first Bev regimen responded to the second Bev regimen (P= 0.72). The median PFS for patients in the CWOB group was 2.6 months (95% confidence interval [CI], 1.3–5 months), compared with 5.0 months (95% CI, 3.5–7.3 months) for patients in the BAB group (P= 0.01). Overall survival was similar, 9.4 months (95% CI, 5.0–12.0 months) for CWOB versus 8.6 months (95% CI, 5.8–15.5 months) for BAB (P= 0.19). One patient in the BAB group died of a bowel perforation.ConclusionsIn patients previously treated with Bev for recurrent ovarian cancer, the subsequent addition of Bev to cytotoxic chemotherapy increased the PFS compared with patients not receiving a second course of Bev, but did so without an impact on overall survival. The response to the first Bev regimen did not predict whether a patient would respond again to the next Bev regimen. Randomized, larger studies will have to be performed to confirm this observation.
