Alpha-fetoprotein (AFP)-producing epithelial ovarian carcinoma (EOC): a retrospective study of 27 cases.

Abstract

ObjectiveThe aim of the study was to investigate the relative risk factors associated with the prognosis and effective treatments of alpha-fetoprotein (AFP)-producing epithelial ovarian carcinoma (EOC).MethodWe presented three cases of AFP-producing EOC and performed a brief review to summarize the clinicopathological features and prognostic factors of 24 cases that have been previously reported. We evaluated the correlations among prognostic and clinical parameters, such as stage, pathology and chemotherapy regimens. In addition, a retrospective review of these 27 cases was conducted, and survival curves were estimated using the Kaplan–Meier method.ResultsThe patients were aged between 23 and 77 years. The median overall survival was 10 months, and ten (37.04%) patients died within 18 months. We compared the overall mean survival times of all patients in different stages, and the results suggest that the postoperative pathological staging is hardly correlated with prognosis (P = 0.76). There was a correlation between pathology and prognosis (P = 0.0018). The mean survival time was longer for patients who had undergone chemotherapy than for those without chemotherapy (14.88 vs 0.65 months) (P < 0.0001). Moreover, although patients had a good response to the regimens for PEB and TC (P = 0.004), there was no significant difference between PEB and TC (P = 0.386).ConclusionsAFP-producing EOC is uncommon and regarded as an extremely malignant type of tumor. Patients with chemotherapy may have a longer survival time; additionally, PEB and TC may be an optimal selection for this kind of tumor. Further large-scale studies are needed to confirm our findings.
