Patients were also divided into high and low grade group according to pathology subtype. The data were analyzed by using Chi-square, univariate and multivariate cox regression methods, and survival was evaluated by Kaplan-Meier method.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included 178 patients with PMP of an appendiceal origin who underwent BSO, and 134 (75.3%) had histopathological confirmed ovarian metastases. In the low-grade group, ovarian involvement and completeness of cytoreduction (CCR) acted as independent predictors of poor prognosis for OS. In normal appearing uterus, ovaries, fallopian tubes, pathologic disease was still found in 15.4%, 7.8%, and 22.8% respectively. In abnormal appearing uterus, ovaries, fallopian tubes, pathologic disease was found in 95.5%, 96.6%, and 94.2% respectively. Moreover, multivariate analysis revealed that a high-grade histopathological subtype of PMP and CCR 2\/3 were independent predictors of OS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Based on these data, strong consideration should be given to removal of gynecologic organs in cases of appendiceal
