Prognosis Following Surgery for Recurrent Ovarian Cancer and Diagnostic Criteria Predictive of Cytoreduction Success: A Systematic Review and Meta-Analysis.

ABSTRACT: For women achieving clinical remission after the completion of initial treatment for epithelial ovarian cancer, 80% with advanced-stage disease will develop recurrence. However, the standard treatment of women with recurrent platinum-sensitive diseases remains poorly defined. Secondary (SCS), tertiary (TCS) or quaternary (QCS) cytoreduction surgery for recurrence has been suggested to be associated with increased overall survival (OS). We searched five databases for studies reporting death rate, OS, cytoreduction rates, post-operative morbidity/mortality and diagnostic models predicting complete cytoreduction in a platinum-sensitive disease recurrence setting. Death rates calculated from raw data were pooled based on a random-effects model. Meta-regression/linear regression was performed to explore the role of complete or optimal cytoreduction as a moderator. Pooled death rates were 45%, 51%, 66% for SCS, TCS and QCS, respectively. Median OS for optimal cytoreduction ranged from 16-91, 24-99 and 39-135 months for SCS, TCS and QCS, respectively. Every 10% increase in complete cytoreduction rates at SCS corresponds to a 7% increase in median OS. Complete cytoreduction rates ranged from 9-100%, 35-90% and 33-100% for SCS, TCS and QCS, respectively. Major post-operative thirty-day morbidity was reported to range from 0-47%, 13-33% and 15-29% for SCS, TCS and QCS, respectively. Thirty-day post-operative mortality was 0-6%, 0-3% and 0-2% for SCS, TCS and QCS, respectively. There were two externally validated diagnostic models predicting complete cytoreduction at SCS, but none for TCS and QCS. In conclusion, our data confirm that maximal effort higher order cytoreductive surgery resulting in complete cytoreduction can improve survival.

Project description:BackgroundSecondary surgical cytoreduction in women with platinum-sensitive, recurrent epithelial ovarian, primary peritoneal, or fallopian-tube ("ovarian") cancer is widely practiced but has not been evaluated in phase 3 investigation.MethodsWe randomly assigned patients with recurrent ovarian cancer who had received one previous therapy, had an interval during which no platinum-based chemotherapy was used (platinum-free interval) of 6 months or more, and had investigator-determined resectable disease (to no macroscopic residual disease) to undergo secondary surgical cytoreduction and then receive platinum-based chemotherapy or to receive platinum-based chemotherapy alone. Adjuvant chemotherapy (paclitaxel-carboplatin or gemcitabine-carboplatin) and use of bevacizumab were at the discretion of the investigator. The primary end point was overall survival.ResultsA total of 485 patients underwent randomization, 240 to secondary cytoreduction before chemotherapy and 245 to chemotherapy alone. The median follow-up was 48.1 months. Complete gross resection was achieved in 67% of the patients assigned to surgery who underwent the procedure. Platinum-based chemotherapy with bevacizumab followed by bevacizumab maintenance was administered to 84% of the patients overall and was equally distributed between the two groups. The hazard ratio for death (surgery vs. no surgery) was 1.29 (95% confidence interval [CI], 0.97 to 1.72; P = 0.08), which corresponded to a median overall survival of 50.6 months and 64.7 months, respectively. Adjustment for platinum-free interval and chemotherapy choice did not alter the effect. The hazard ratio for disease progression or death (surgery vs. no surgery) was 0.82 (95% CI, 0.66 to 1.01; median progression-free survival, 18.9 months and 16.2 months, respectively). Surgical morbidity at 30 days was 9%; 1 patient (0.4%) died from postoperative complications. Patient-reported quality of life decreased significantly after surgery but did not differ significantly between the two groups after recovery.ConclusionsIn this trial involving patients with platinum-sensitive, recurrent ovarian cancer, secondary surgical cytoreduction followed by chemotherapy did not result in longer overall survival than chemotherapy alone.

Project description:Background and objectives: The Gold-Standard treatment for Advanced Epithelial Ovarian Cancer remains cytoreductive surgery followed by systemic chemotherapy. Surgery can be performed either by an open or minimally invasive approach (MIS), although the former remains the most widely used approach. Recently, Van Driel et al. proved that adding 100 mg/m2 of Cisplatin in Hyperthermic Intraperitoneal Chemotherapy (HIPEC) at Interval Debulking Surgery (IDS) gives a disease-free survival (DFS) advantage. Similarly, Gueli-Alletti et al. demonstrated how the MIS approach is feasible and safe in IDS. Moreover, Petrillo et al. reported pharmacokinetic profiles with a higher chemotherapy concentration in patients undergoing HIPEC after MIS compared with the open approach. Therefore, the following review investigates the oncological and clinical safety consequences of the association between MIS and HIPEC. Methods: Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in April 2022. Studies containing data about oncological and safety outcomes were included. We registered the Review to the PROSPERO site for meta-analysis with protocol number CRD42022329503. Results: Five studies fulfilled inclusion criteria. 42 patients were included in the review from three different Gynecological Oncological referral centers. The systematic review highlighted a Recurrence Rate ranging between 0 and 100%, with a 3-year Platinum-Free Survival between 10 and 70%. The most common HIPEC drug was Cisplatin, used at concentrations between 75 and 100 mg/m2 and at an average temperature of 42 °C, for 60 to 90 min. Only 1 Acute Kidney Insufficiency has been reported. Conclusions: The scarcity of clinical trials focusing on a direct comparison between MIS and the open approach followed by HIPEC in EOC treatment does not make it possible to identify an oncological advantage between these two techniques. However, the safety profiles shown are highly reassuring.

Project description:The ovarian cancer recurrence occurs in 75% of patients with advanced FIGO stage, and its treatment is a challenge for the oncologist in gynecology. The standard treatment of recurrent ovarian cancer (ROC) usually includes intravenous chemotherapy according to platinum sensitivity. Furthermore, maintenance treatment with target therapies [e.g., anti-angiogenic drug or PARP inhibitors (PARPi)], should be provided if not precedently administrated. In this scenario, secondary cytoreductive surgery (SCS) remains a practical but controversial option for platinum-sensitive ROC (PSROC). So far, several retrospective series and a Cochrane meta-analysis had concluded that SCS could determine better survival outcomes in ROC with favorable prognostic characteristics, such as the presence of a single anatomical site of recurrence, or when patients are accurately selected for surgery based on complete resection's predictive models. Recently, three randomized clinical trials (RCTs) investigated the role of SCS in PSROC patients selected with different criteria. All the three RCTs showed a significant statistical advantage in progression-free survival (PFS) in the SCS group, with an even more significant difference in patients with complete cytoreduction (about 7-month PFS increased). Data on overall survival (OS) are different in the two completed trials. The GOG213 study has documented a longer OS of PSROC patients who received chemotherapy alone compared to surgery plus chemotherapy. Contrarily, the DESKTOP III trial showed 7.7 months of increased OS in the surgery group vs. chemotherapy alone, with a more difference in the complete tumor cytoreduction (CTC) group (12 months). These RCTs thereby suggest that undergoing complete cytoreduction may not be the only key and that the disease biology may also matter. Few recent retrospective series investigated the role of SCS according to BRCA mutation status and the effect of SCS in patients receiving emerging PARPi. A consequence of the developments in SCS and knowledge of different molecular pathways influencing the recurrent disease is that the future research objective should be to individualize and personalize the surgical approach.
