Overview

abstract

  • OBJECTIVE: The objective of our study was to describe the accuracy of intraoperative frozen-section diagnosis of carcinoma metastatic to the adnexa in women with a history of breast or colorectal carcinoma. METHODS: We conducted a retrospective chart review of all patients with a history of breast or colorectal carcinoma who developed histologically proven pelvic or abdominal metastases between 1988 and 1995. In those patients whose final histologic review revealed carcinoma metastatic to the adnexa, the accuracy of the intraoperative frozen-section diagnosis of the adnexal tumor was compared to the final diagnosis. RESULTS: Forty-three patients were identified and in 36 patients the frozen section was obtained from the adnexa. Twenty-one patients (58.3%) had metastatic breast carcinoma and 15 (41.7%) had metastatic colorectal carcinoma to the adnexa. Carcinoma in the adnexa was correctly diagnosed by frozen section in 35 of 36 patients (97.2%). Metastatic carcinoma was identified at frozen section in 17 of 21 patients (81%) with metastatic breast cancer and 13 of 15 patients (86.7%) with metastatic colorectal cancer. In 3 of 21 patients (14.3%) with metastatic breast cancer and in 2 of 15 patients (13.3%) with metastatic colorectal cancer, the frozen-section diagnosis was carcinoma of uncertain origin. One patient had a false-negative frozen section because the small focus of metastatic breast cancer was not sampled at the time of frozen section. CONCLUSION: Intraoperative frozen-section evaluation correctly diagnosed carcinoma in the adnexa in 97% of patients, and in over 80% of cases, the carcinoma was diagnosed as being metastatic in origin.
