Objective To analyze the characteristics of hepatic metastasis of pure immature ovarian teratoma and explore its proper diagnosis and *** Eighteen cases of hepatic metastasis of pure immature ovarian teratoma were included in this study. The clinical stage, operation, chemotherapy and histopathology of primary and secondary tumors as well as the data from long term follow-ups were analyzed retrospectively,Results All of the hepatic metastatic tumors were located on the surface of the liver. 61.1％ (11/18) of them were clinical stage Ⅲ and 44.4％ (8/18) were grade 1 at first operation. The hepatic metastatic rate was 16.7％ (3/18) in the standard adjuvant chemotherapy group but increased markedly to 31.2％ (15/48) in the irregular chemotherapy group. Auxiliary diagnostic methods could not indicate the correct results. The surgical resection rate of hepatic metastasis of pure immature ovarian teratoma was 94.4％ (17/18). There were less complications in the group with tumor diameter less than 15 cm. The follow-up time ranged from 3 to 205 months with a mean of 20.9 months. The 3-year-survival rate was 77.8％ (14/ 18), and mortality rate was 22.2％. The 5- and 10-year-survival rate was 55.6％ (10/18) and 38.9％ (7/18), respectively. The rate of loss in follow-up was 22.2％ (4/18) and 38.9％ (7/18), respectively, and one patient has survived for more than 17 *** The hepatic metastatic rate of pure immature ovarian teratoma could be decreased using standard adjuvant chemotherapy. Suitable surgical treatment could reduce complications and improve the prognosis for patients.
