Background Oophorectomy is a common procedure in women with peritoneal metastasis (PM) undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), which has unique consequences on hormonal balance and fertility before menopause. The objective of this study was to analyze histopathological results and the prognostic influence of ovarian involvement. Material and methods A prospective HIPEC database was used to identify 442 patients with PM from colorectal cancer, pseudomyxoma peritonei and appendix cancer scheduled for CRS-HIPEC between 2012 and 2019 at the University Hospital, Uppsala, Sweden. Statistical analyses were performed using the Chi-square test and Cox regression analysis. Results In all, 103 of 180 females underwent oophorectomy. Unilateral oophorectomy was performed in 19% (n = 20) and bilateral oophorectomy in 81% (n = 83). The median age was 61 (range 20-80). Benign ovarian histopathology was seen in 23% (n = 24). Of these, two patients were ≤35 years and 8 patients ≤50 years. The median peritoneal cancer index (PCI) was 16 in women undergoing oophorectomy, and 7 in those with no oophorectomy. Bilateral oophorectomy was associated with negative impact on overall survival (HR 4.84; 95% CI; 1.14-20.61). Malignant ovarian histopathology was also associated with a negative impact on overall survival (p = 0.043). Conclusion Almost a quarter of the patients had benign histopathology after oophorectomy. This is crucial information for females with childbearing potential when planning for extensive surgery. Extensive pelvic peritoneal cancer growth resulted more often in bilateral oophorectomy which influenced survival negatively.
