Objective: The prognosis of ovarian granulosa cell tumors is difficult to predict by conventional histological methods. Study design: The tumors of 30 patients operated on for a granulosa cell tumor were retrospectively studied for the expression of the inhibin a-subunit. The immunohistochemical staining results were correlated to the FIGO stage of the tumor and the prognosis of the patients. Results: Twenty-six (87%) of the ovarian granulosa cell tumors stained positively for the inhibin a-subunit. All FIGO stage I and II tumors expressed inhibin a-subunit. All FIGO stage l and II tumors expressed inhibin, whereas the majority of stages Ill and IV did not (p = 0.001, χ2-test)/ The survival of the patients with inhibin immunopositive tumors was significantly longer (median 183 months, SE 41, p = 0.000, log rank test) than that of patients without inhibin expression (median 2.5 months, SE 5.25). Conclusions: Patients with ovarian granulosa cell tumors with a potential to produce the inhibin a-subunit may have a more favo­rable prognosis than those with inhibin immunonegative tumors.
