Objective: To compare 30-day postoperative complications for patients with advanced ovarian cancer who underwent resection to no gross residual disease versus optimal and suboptimal cytoreduction. Methods: A retrospective cohort study of women drawn from the National Surgical Quality Improvement Program who underwent cytoreductive surgery for advanced ovarian cancer between 2014 and 2019 was performed. Exposure of interest was extent of surgical resection defined as no gross residual disease; residual disease <1 cm (optimal); and residual disease >1 cm (suboptimal). Primary outcome was postoperative complication. Associations were examined with bivariable tests and multivariable logistic regression. Results: A total of 2248 women underwent cytoreductive surgery; 68.4% (n = 1538) underwent resection to no gross residual disease, 22.4% (n = 504) had an optimal, and 9.2% (n = 206) had a suboptimal cytoreduction. Optimal cytoreduction patients had the highest rates of any postoperative complication (35.5%, p < 0.001). They also had the longest operative times and procedures that were most surgically complex (203 min, 43.6 relative value units, both p < 0.05). However, patients who underwent optimal cytoreduction did not have increased odds of major complications (adjusted odds ratio: 1.20, 95% confidence interval: 0.91–1.58). Conclusion: Patients who underwent optimal cytoreduction had more postoperative complications, required the most operating room time, and represented more complex surgeries compared with suboptimal cytoreduction or resection to no gross residual disease.
