N2 - Objective: To compare the ability of current complication reporting scales (Contracted Accordion Scale, Expanded Accordion Scale, Clavien-Dindo Scale) to reflect the severity of patient outcomes after cytoreductive surgery for ovarian cancer. Methods: We included all patients undergoing primary debulking surgery for stage IIIC/IV ovarian cancer from 2006 to 2016 at two expert centers for ovarian cancer. Complications within 30 days of surgery were graded according to three scales. Outcomes included length of stay, mortality (90-day), and delayed initiation of chemotherapy (>42 days after surgery). Correlations were assessed using the Spearman rank correlation, and comparisons between groups were evaluated using the Wilcoxon rank-sum test and the χ2 test. Results: Among the 892 patients, 185 (20.7%) patients had a grade 3 or higher complication per all scales. Patients with grade 3 or higher complications (compared with those with none, grade 1 or grade 2) had longer length of stay, higher 90-day mortality, and delayed initiation of chemotherapy. The expanded scales (Expanded Accordion Scale and Clavien Dindo Scale) provided a more refined characterization of outcome compared with the Contracted Accordion Scale. However, mortality was actually found to be as high as 25.0% for grade 5 complications using the Expanded Accordion Scale. Patients with organ failure or requiring an invasive procedure had significantly worse outcomes than those without either complication, highlighting the importance of separating these events. Conclusions: All three scales demonstrated general correlation with important outcomes after ovarian cancer surgery. However, the expanded scales (Clavien Dindo Scale and Expanded Accordion Scale) used important events commonly encountered after cytoreductive surgery, provided a more refined view of the severity of complications, and should be used in reporting outcomes in ovarian cancer.
