Laparoscopic Surgical Algorithm to Triage the Timing of Tumor Reductive Surgery in Advanced Ovarian Cancer.

ABSTRACT: OBJECTIVE:To estimate the effects of a laparoscopic scoring algorithm to triage patients with advanced ovarian cancer to immediate or delayed debulking to improve complete gross surgical resection rates and determine the resulting clinical outcomes. METHODS:We prospectively performed laparoscopic assessment on patients with suspected advanced-stage ovarian cancer from April 2013 to December 2016 to determine primary resectability at tumor reductive surgery. Patients with medically inoperable or distant metastatic disease received neoadjuvant chemotherapy. Two-surgeon scoring was performed in a blinded fashion using a validated scoring method. Patients with predictive index value scores less than 8 were offered primary surgery and those with scores 8 or greater received neoadjuvant chemotherapy. Univariate and multivariate analysis was performed for effects on progression-free survival. RESULTS:Six hundred twenty-one patients presenting with presumed advanced ovarian cancer were evaluated during the study period and 488 patients met inclusion criteria. Two hundred fifteen patients underwent laparoscopic scoring, of whom 125 had predictive index value scores less than 8 and 84 had predictive index value scores 8 or greater. Blinded two-surgeon predictive index value scoring resulted in bivariate discordance in only 2% of patients. Tumor cytoreduction led to no gross residual disease (R0 resection) in 88% of patients in the primary surgery group and 74% in the neoadjuvant chemotherapy group. Patients triaged to primary surgery had an improved progression-free survival of 21.4 months versus 12.9 months in those patients undergoing neoadjuvant chemotherapy (P<.001). Median progression-free survival by treatment group and residual disease status was as follows: primary surgery-R0 23.5 months; primary surgery-R1 (any gross residual disease) 17.6 months; neoadjuvant chemotherapy-R0 15.5 months; and neoadjuvant chemotherapy-R1 12.9 months (P<.001). On multivariate analysis for progression-free survival, baseline CA 125 (P=.001) and gross residual disease at tumor reductive surgery (P=.01) were significantly associated with progression-free survival. CONCLUSION:Laparoscopic triage assessment allowed for a personalized approach to the management of patients with advanced ovarian cancer and resulted in high complete surgical resection rates at tumor reductive surgery.

Project description:BackgroundThis study investigated the feasibility and safety of laparoscopic splenectomy conducted in the contexts of both laparoscopic secondary surgery for isolated recurrence in the spleen and primary laparoscopic cytoreductive surgery for advanced ovarian cancer.MethodsWe performed a perspective observational study including all consecutive patients with ovarian cancer who underwent laparoscopic splenectomy as part of primary cytoreductive procedures for advanced stage ovarian cancer or secondary surgery for isolated splenic recurrence between January 2016 and May 2020.ResultsWe enrolled 13 consecutive patients, candidate to laparoscopic splenectomy as part of primary cytoreductive procedures for advanced stage ovarian cancer (6 patients) or secondary surgery for isolated splenic recurrence of platinum-sensitive ovarian cancer (7 patients). Median operative time (509 min [range, 200-845]) for primary cytoreductive surgery varied according to surgical complexity depending on the extensiveness of the disease. Median operative time for secondary surgery for isolated splenic metastasis was 253 min (90-380). Only 1 patient with isolated splenic recurrence required conversion to an open approach. No intraoperative complication occurred, and no intraoperative blood transfusions were required. Median hospital stay was 3 days (range, 2-5) for isolated recurrence and 9 days (7-18) for primary cytoreductive surgery. Complete tumor resection was achieved in all patients. Median time from surgery to adjuvant chemotherapy was 16 days (7-24). All six patients who underwent laparoscopic splenectomy during primary cytoreductive surgery remain alive, four of whom exhibit no evidence of disease (median follow-up 25 months [4-36]). Among patients who underwent laparoscopic splenectomy during secondary surgery for isolated splenic relapse, all patients are alive and only one had a central diaphragmatic relapse 2 years after surgery (median follow-up 17 months ([5-48 months]).ConclusionsThe laparoscopic approach to splenectomy is feasible and safe both in patients undergoing primary cytoreductive surgery for advanced stage disease and those with isolated recurrence of ovarian cancer, without compromising survival and allowing early initiation of postoperative systemic chemotherapy.

Project description:OBJECTIVES:Neoadjuvant chemotherapy (NACT) versus primary debulking surgery (PDS) for advanced epithelial ovarian cancer (AEOC) remains controversial in the United States. Generalizability of existing trial results has been criticized because of less aggressive debulking procedures than commonly used in the United States. As a result, economic evaluations using input data from these trials may not accurately reflect costs and outcomes associated with more aggressive primary surgery. Using data from an ongoing trial performing aggressive debulking, we investigated the cost-effectiveness and cost-utility of NACT versus PDS for AEOC. METHODS:A decision tree model was constructed to estimate differences in short-term outcomes and costs for a hypothetical cohort of 15,000 AEOC patients (US annual incidence of AEOC) treated with NACT versus PDS over a 1-year time horizon from a Medicare payer perspective. Outcomes included costs per cancer-related death averted, life-years and quality-adjusted life-years (QALYs) gained. Base-case probabilities, costs, and utilities were based on the Surgical Complications Related to Primary or Interval Debulking in Ovarian Neoplasms trial. Base-case analyses assumed equivalent survival; threshold analysis estimated the maximum survival difference that would result in NACT being cost-effective at $50,000/QALY and $100,000/QALY willingness-to-pay thresholds. Probabilistic sensitivity analysis was used to characterize model uncertainty. RESULTS:Compared with PDS, NACT was associated with $142 million in cost savings, 1098 fewer cancer-related deaths, and 1355 life-years and 1715 QALYs gained, making it the dominant treatment strategy for all outcomes. In sensitivity analysis, NACT remained dominant in 99.3% of simulations. Neoadjuvant chemotherapy remained cost-effective at $50,000/QALY and $100,000/QALY willingness-to-pay thresholds if survival differences were less than 2.7 and 1.4 months, respectively. CONCLUSIONS:In the short term, NACT is cost-saving with improved outcomes. However, if PDS provides a longer-term survival advantage, it may be cost-effective. Research is needed on the role of patient preferences in tradeoffs between survival and quality of life.
