OBJECTIVE: The aim of this study was to evaluate transvaginal sonography (TVS)-guided core biopsy of the adnexal masses for neoadjuvant chemotherapy (NACT) in patients with advanced ovarian malignancies.
MATERIALS AND METHODS: We retrospectively reviewed the medical records of 52 patients who had undergone TVS-guided core biopsies in our gynecologic cancer center between May 2009 and October 2015. TVS-guided core biopsies were performed on patients with advanced ovarian malignancies who were considered as candidates for NACT and patients with adnexal masses who required a differential diagnosis of non-gynecologic tumors.
RESULTS: Thirty-seven patients (71.2%) were scheduled to undergo NACT owing to the presence of coexisting illness, age, tumor burden, and location of metastatic sites. Fifteen patients (28.8%) underwent TVS-guided core biopsies to determine if they had primary or secondary ovarian tumors. Histopathologic examinations revealed primary ovarian tumors in 44 patients (84.6%). Nongynecologic tumors including gastrointestinal stromal tumor and metastatic tumor from gallbladder, gastric, and colorectal cancer were found to be the second most common disease (n = 5 [9.6%]). Findings in the samples were nondiagnostic in 4 patients (5.8%). With respect to the histological concordance rate between TVS-guided core biopsy and surgical specimen, diagnostic accuracy was 93.6%. There were no biopsy-related complications.
CONCLUSIONS: TVS-guided core biopsy may be a feasible procedure to diagnose adnexal masses, particularly in patients with advanced ovarian malignancies who are more likely to benefit from NACT.
