    Author: Zhang GN.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1993 Oct; 28(10):601-3, 635. PubMed ID: 8112130.
    Abstract:
    One hundred and thirty-six frozen section of ovarian tumors were compared with the paraffin sections during 1986-1992. The final histological diagnosis were: benign 52 cases, borderline malignant 22 cases, and malignant 62 cases. The accurate rate of the frozen section method for malignant was 93.5%, benign was 100.0% and borderline malignant was 77.2%. Predictive values were computed: 100.0% for malignant, 85.0% for borderline malignant and 89.6% for benign disease. Analysis of the 9 false negative revealed that 8 cases were sampling error and most occurred in mucinous borderline tumors. Our data showed that the frozen section was a relative accurate and reliable method for diagnosis of ovarian tumor during operation.
