Abstract

Purpose To examine the utility of upper abdominal procedures (UAPs) performed in a cohort of optimally cytoreduced patients with advanced stage epithelial ovarian cancer (EOC) or primary peritoneal cancer (PPC) and identify potential areas where aggressive surgery may impact survival. Patients and methods We reviewed 2655 patients enrolled in Gynecologic Oncology Group (GOG) 182 who had complete resection (CR) or minimal residual (MR) disease < 1 cm. Demographic, pathologic, surgical, and outcome data were collected. UAPs included diaphragm stripping or resection, liver resection, splenectomy, pancreatectomy, and porta hepatis surgery. Effect of UAP and CR on PFS/OS was assessed by Kaplan-Meier and proportional hazards methods. Results Four-hundred eighty-two patients (18.1%) underwent a total of 590 UAPs. There were 351 (13.1%) diaphragm surgeries, 112 (4.2%) liver surgeries, 108 (4%) splenectomies, 12 (0.5%) pancreatectomies, and 7 (0.2%) porta hepatis surgeries. Comparing patients who did not have UAPs to patients who had UAPs, the PFS was 18.2 months (mos) and 14.8 mos (p < 0.01) and OS was 49.8 mos v. 43.7 mos (p = 0.01), respectively. However, in the multivariable analysis this survival benefit did not remain (PFS HR = 1.03, 95% CI 0.91-1.15; OS HR = 0.92, 95%CI 0.81-1.04). The OS of the 141 patients who had an UAP and achieved CR compared to the 341 patients who had an UAP with MR was 54.6 compared to 40.4 mos (p = 0.0005). Conclusions UAP procedures should only be performed when CR is attainable. A significant proportion of patients with MR were left with diaphragmatic disease that could potentially be completely resected.
