ABSTRACT
OBJECTIVE:
To assess the impact on survival of major postoperative complications and to identify the factors associated with these complications in patients with advanced ovarian cancer after cytoreductive surgery.METHODS:
We designed a retrospective multicenter study collecting data from patients with IIIC-IV FIGO Stage ovarian cancer who had undergone either primary debulking surgery (PDS), early interval debulking surgery (IDS) after 3-4 cycles of neoadjuvant chemotherapy, or delayed debulking surgery (DDS) after 6 cycles, with minimal or no residual disease, from January 2008 to December 2015. Univariable and multivariable analyses were conducted to identify factors associated with major surgical complications (≥Grade 3). We assessed disease-free survival (DFS) and overall survival (OS) rates according to the occurrence of major postoperative complications.RESULTS:
549 women were included. The overall rate of major surgical complications was 22.4%. Patients who underwent PDS had a higher rate of major complications (28.6%) than patients who underwent either early IDS (23.2%) or DDS (14.0%). Multivariable analysis revealed that extensive peritonectomy and surgical timing were associated with the occurrence of major complications. Median DFS and OS were 16.9 months (95%CI = [13.7-18.4]) and 48.0 months (95%CI = [37.2-73.1]) for the group of patients with major complications, and 20.1 months (95%CI = [18.6-22.4]) and 56.7 months (95%CI = [51.2-70.4]) for the group without major complications. Multivariable analysis revealed that major surgical complications were significantly associated with DFS, but not with OS.CONCLUSIONS:
Patients who experienced major surgical complications had reduced DFS, compared with patients without major morbidity. Extensive peritonectomy and surgical timing were predictive factors of postoperative morbidity.Key words
