Abstract
Introduction
To compare the effect of bowel resection vs stripping on the clinical outcomes of patients with FIGO II–IV ovarian cancer.
Methods
We retrospectively analyzed patients with FIGO II–IV ovarian cancer who suffered from bowel involvement and underwent cytoreductive surgery between January 2014 and March 2022. Patients’ survival was compared by Kaplan–Meier survival analysis and Cox proportional hazards models.
Results
Four hundred and twelve patients were included. 48 patients underwent bowel resection (BR), and 364 patients underwent bowel tumor stripping (BTS). The BR group had longer operative duration, hospital stay, time to post-operative chemotherapy, and more intraoperative bleeding. The median PFS was 37 months (95% CI 12–62) in BTS compared to 25 months (95% CI 10–40) in BR among patients who achieved R0 resection (p = 0.590). Among those with R1 resection, the median PFS in BST was 23 months (95% CI 16–30) and that in BR was 15 months (95% CI 12–18, p = 0.136); moreover, a favorable median PFS was observed in BTS with residual bowel lesions (23 months, 95% CI 14–32), compared to BR (15 months, 95% CI 12–18, p = 0.144). Multivariate analysis indicated that FIGO stage, PCI, cytoreduction time and residual lesions were independent prognostic factors of PFS.
Conclusion
For patients with FIGO stage II–IV ovarian cancer with bowel implicated, bowel resection is necessary to achieve complete removal to improve the survival. If complete resection was judged unfeasible, cautious decision of bowel resection is required. Neoadjuvant chemotherapy might reduce the ratio of bowel resection for some with mesenteric involvement.
