5534 Background: NORA is the first, phase III, randomized controlled trial (RCT) that demonstrated individualized starting dose regimen of niraparib, which significantly improved PFS in Chinese patients with platinum-sensitive recurrent ovarian cancer (PSROC). This sub-group analysis evaluated the efficacy of niraparib maintenance therapy with and without secondary cytoreductive surgery (SCS) in PSROC. Methods: The NORA phase III RCT included adult (≥18 years) Chinese women with PSROC who were randomized in a 2:1 ratio to receive oral niraparib (n = 177) or matched placebo (n = 88). This retrospective subgroup analysis was based on the progression-free survival (PFS) of niraparib maintenance therapy in these two groups of patients with PSROC, patients with SCS, and patients without SCS. The PFS was assessed by blinded independent central review. The Kaplan-Meier (KM) estimator and log-rank test were performed to calculate the median PFS time. Results: Of the 265 evaluable patients, 69 (26.0%) patients received the SCS (niraparib, n = 48; placebo, n = 21), and 196 (74.0%) patients were without SCS (niraparib, n = 129; placebo, n = 67). Among patients with and without SCS, baseline characteristics for BRCA mutation were 26.1% vs 41.8%, complete response to last platinum-based chemotherapy were 68.1% vs 43.9%, time (6-12 months) to progression after penultimate therapy were 23.2% vs 34.7%, respectively. Treatment with niraparib led to a significant reduction of risk to disease progression compared with placebo in patients with SCS (Hazard ratio [95% CI]: 0.32 [0.13–0.78]; P = 0.0102) and without SCS (0.34 [0.23–0.50]; P< 0.001). Moreover, in the subgroups of patients who received SCS, niraparib maintenance therapy had a significantly longer PFS compared with placebo (Median [95% CI]: not reached [18.33 – not estimable] vs 5.75 months [3.68 – not estimable]; P = 0.0102). This trend was also similar in the subgroup of patients who did not receive SCS (Median [95% CI]: 10.28 months [7.49 – 18.37] vs 4.90 months [3.71 – 5.52]; P < 0.0001). Conclusions: The results from this retrospective sub-group analysis revealed that niraparib maintenance therapy provided significant clinical efficacy in patients with PSROC, irrespective of SCS. Clinical trial information: NCT03705156.

Abstract Objective The aim of this meta-analysis was to assess the effectiveness and safety of secondary cytoreductive surgery plus chemotherapy (SCS + CT) in recurrent ovarian cancer (ROC). Our secondary purpose was to analyze whether patients could benefit from complete resection. Methods We searched EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials, from inception to April 2021. We used appropriate scales to assess the risk of bias. Data from included studies that reported median PFS or OS were weighted by individual study sample size, and aggregated for meta-analysis. We calculated the pooled proportion of complications within 30 days after surgery. Results We identified 13 articles, including three RCTs and ten retrospective cohort studies. A total of 4572 patients were included, of which 916 patients achieved complete resection, and all patients were comparable at baseline. Compared with chemotherapy alone, SCS + CT significantly improved the PFS (HR = 0.54, 95% CI: 0.43–0.67) and OS (HR = 0.60, 95% CI: 0.44–0.81). Contrary to the results of cohort studies, the meta-analysis of RCTs showed that SCS + CT could not bring OS benefits (HR = 0.93, 95% CI: 0.66–1.3). The subgroup analysis showed the prognostic importance of complete resection. Compared with chemotherapy alone, complete resection was associated with longer PFS (HR = 0.53, 95% CI: 0.45–0.61) and OS (HR = 0.56, 95% CI: 0.39–0.81), while incomplete resection had no survival benefit. Additionally, complete resection could maximize survival benefit compared with incomplete resection (HR = 0.56, 95% CI: 0.46–0.69; HR = 0.61, 95% CI: 0.50–0.75). The pooled proportion for complications at 30 days was 21% (95% CI: 0.12–0.30), and there was no statistical difference in chemotherapy toxicity between the two groups. Conclusion The review indicated that SCS + CT based regimens was correlated with better clinical prognosis for patients with recurrent ovarian cancer, but the interpretation of OS should be cautious. The meta-analysis emphasizes the importance of complete resection, suggesting that the potential benefits of prolonging survival may outweigh the disadvantages of any short-term complications associated with surgery.

Ago Score

The most advanced epithelial ovarian cancer develops recurrent disease despite maximal surgical cytoreduction and adjuvant platinum-based chemotherapy. Treatment with secondary cytoreductive surgery (SCS) combined with chemotherapy or with chemotherapy alone for patients with platinum-sensitive recurrent ovarian cancer (ROC) is currently under heated discussion. Encouragingly, the results of the AGO DESKTOP III Study and the SOC1/SGOG-OV2 trial, which have been published recently, showed a striking advantage in terms of overall survival (OS) and progression-free survival (PFS) of ROC patients undergoing SCS compared to chemotherapy alone; moreover, a benefit of SCS exclusively for patients with complete gross resection (CGR) was particularly highlighted. CGR is considered the ultimate goal of SCS, on condition that the balance between maximal survival gain and minimal operative morbidity is maintained. Several models have been proposed to predict the rate of CGR, such as the MSK criteria, the AGO score, and the Tian model, over the last 15 years. This summary is mainly about the several previously published prediction models for CGR in SCS of ROC patients and discusses the effectiveness and limitations of these prediction models.

PURPOSE The purpose of this phase II study was to evaluate hyperthermic intraperitoneal chemotherapy (HIPEC) with carboplatin for recurrent ovarian cancer during secondary cytoreductive surgery. MATERIALS AND METHODS Patients were intraoperatively randomly assigned to carboplatin HIPEC (800 mg/m2 for 90 minutes) or no HIPEC, followed by five or six cycles of postoperative IV carboplatin-based chemotherapy, respectively. Based on a binomial single-stage pick-the-winner design, an arm was considered winner if ≥ 17 of 49 patients were without disease progression at 24 months post-surgery. Secondary objectives included postoperative toxicity and HIPEC pharmacokinetics. RESULTS Of 98 patients, 49 (50%) received HIPEC. Complete gross resection was achieved in 82% of the HIPEC patients and 94% of the standard-arm patients. Bowel resection was performed in 37% of patients in the HIPEC arm compared with 65% in the standard ( P = .008). There was no perioperative mortality and no difference in use of ostomies, length of stay, or postoperative toxicity. At 24 months, eight patients (16.3%; 1-sided 90% CI, 9.7 to 100) were without progression or death in the HIPEC arm and 12 (24.5%; 1-sided 90% CI, 16.5 to 100) in the standard arm. With a medium follow-up of 39.5 months, 82 patients progressed and 37 died. The median progression-free survival in the HIPEC and standard arms were 12.3 and 15.7 months, respectively (hazard ratio, 1.54; 95% CI, 1 to 2.37; P = .05). There was no significant difference in median overall survival (52.5 v 59.7 months, respectively; hazard ratio, 1.39; 95% CI, 0.73 to 2.67; P = .31). These analyses were exploratory. CONCLUSION HIPEC with carboplatin was well tolerated but did not result in superior clinical outcomes. This study does not support the use of HIPEC with carboplatin during secondary cytoreductive surgery for platinum-sensitive recurrent ovarian cancer.
