Abstract
Prognostic Importance of Complications after Primary or Interval Cytoreductive Surgery in Advanced Stage Ovarian Cancer
Macroscopically radical surgery is the goal of ovarian cancer treatment. Relapse-free and overall survival are much shorter if residual tumor exceeds even 1 mm during primary debulking surgery (PDS) or interval debulking surgery (IDS).
This study included 208 patients with primary ovarian cancer stage IIB-IVB and 41 patients with relapsed ovarian cancer treated between 2009 and 2017 at the Department of Obstetrics and Gynaecology, University Hospital, Uppsala, Sweden. PDS was performed in 129 patients (62%), and NACT with subsequent IDS in 79 patients (38%). Complete cytoreduction, CC-0, was achieved in 155 (74,5%) cases. CC-1 was achieved in 35 patients (16,8%).
Median overall survival after PDS with CC-0 was 79 months compared to 45 months after PDS with CC-1, and 37 months after IDS with CC-0.
We analyzed the risk for high-grade 3-4 morbidity (Clavien-Dindo classification of surgical complications) within 30 days after cytoreductive surgery by evaluating the impact of patient-, disease- and surgery-related factors.
Class 3a to 5 morbidity was observed in 60 (24,1%) of 249 analyzed patients. The incidence of high-grade morbidity decreased from 41% to 17% when comparing 2009-2013 versus 2014-2017.
Platelet count, albumin concentration, PCI (peritoneal carcinomatosis index) exceeding 20, CC-0, large bowel resection including colectomy and SCS (surgical complexity score) exceeding 8 were significant risk factors in univariate analysis. High-grade morbidity class 3-4 did not influence overall survival (p=0,47). In the multivariate analysis, platelet count remained an independent factor for overall survival (HR 9,25; 95% CI 1,74 to 49,21), while albumin concentration (p=0,086) and large bowel resection (p=0.07) tended to influence survival.
