STUDY OBJECTIVE: To compare the accuracy of frozen section diagnosis of borderline ovarian tumors among 3 distinct types of hospital-academic hospital with gynecologic pathologists, academic hospital with nongynecologic pathologists, and community hospital with nongynecologic pathologists-and to determine if surgical staging alters patient care or outcomes for women with a frozen section diagnosis of borderline ovarian tumor. DESIGN: Retrospective study (Canadian Task Force classification II-1). SETTING: Tertiary care, academic, and community hospitals. PATIENTS: Women with an intraoperative frozen section diagnosis of borderline ovarian tumor at 1 of 3 types of hospital from April 1998 through June 2016. INTERVENTIONS: Comparison of final pathology with intraoperative frozen section diagnosis. MEASUREMENTS AND MAIN RESULTS: Two hundred twelve women met the inclusion criteria. The frozen section diagnosis of borderline ovarian tumor correlated with the final pathologic diagnosis in 192 of 212 cases (90.6%), and the rate of correlation did not differ among the 3 hospital types (p = .82). Seven tumors (3.3%) were downgraded to benign on final pathologic analysis and 13 (6.1%) upgraded to invasive carcinoma. The 3 hospital types did not differ with respect to the proportion of tumors upgraded to invasive carcinoma (p = .62). Mucinous (odds ratio, 7.1; 95% confidence interval, 2.1-23.7; p = .002) and endometrioid borderline ovarian tumors (odds ratio, 32.4; 95% confidence interval, 1.8-595.5; p = .02) were more likely than serous ovarian tumors to be upgraded to carcinoma. Only 88 patients (41.5%) underwent lymphadenectomy, and only 1 (1.1%) had invasive carcinoma in a lymph node. CONCLUSIONS: A frozen section diagnosis of borderline ovarian tumor correlates with the final pathologic diagnosis in a variety of hospital types.
