Granulosa cell tumor (GCT) is a rare type of ovarian malignancy with poor prognosis of recurrence. Anti-Mullerian hormone (AMH) is a promising serum biomarker for early diagnosis GCT, therefore we assessed its accuracy and clinical value. A meta-analysis was performed to estimate the diagnostic accuracy. We searched the PubMed, Cochrane Literature Library and EMBASE database. After filtering, five studies met our criteria. Two independent reviewers extracted data and total 421 serum samples (70 GCT serum samples and 351 controls) were included in our analysis. The pooled values of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and Summary receiver operating characteristic (SROC) were calculated to assess the accuracy. The pooled estimated for AMH were sensitivity: 0.89 (95 % CI 0.78-0.95), specificity: 0.93 (95 %CI 0.83-0.97). The area under the SROC was 0.93 (95 %CI 0.91-0.95). Serum AMH can be used as a biomarker in clinical diagnosis of GCT with high accuracy. Copyright © 2020 Elsevier B.V. All rights reserved.
