Impact of resection for ovarian metastases from colorectal cancer and clinicopathologic analysis: A multicenter retrospective study in Japan

Abstract Aim The aim of this study was to clarify the significance resection ovarian metastases from colorectal cancer and identify clinicopathologic characteristics. Methods In multicenter retrospective study, we evaluated data on obtained patients at 20 centers in Japan between 2000 2014. We examined impact prognosis with prognostic factors. Results included 296 metastasis. 3‐y overall survival rate 68.6% for solitary metastases. all cases cohort, rates after curative resection, noncurative nonresection were 65.9%, 31.8%, 6.1%, respectively (curative vs [ P < 0.01] 0.01]). multivariate analysis factors, tumor size metastasis ( 0.01), bilateral = peritoneal pulmonary 0.04), liver remnant 0.01) statistically significantly different. Conclusion shown be relatively favorable as Stage IV cancer. Resection metastases, not only but also confers a benefit. Prognostic factors large presence extraovarian
