A suprasellar embryonal carcinoma producing alpha-fetoprotein and human chorionic gonadotropin; treated with combined chemotherapy followed by radiotherapy

Abstract A case of primary suprasellar embryonal carcinoma that produced alpha-fetoprotein and human chorionic gonadotropin in a 12-year-old girl is reported. Partial removal of the tumor and cis -platinum-based combined chemotherapy followed by local radiotherapy resulted in a definite regression of the tumor and improvement from clinical signs and symptoms. After these treatments, the concentrations of alpha-fetoprotein and human chorionic gonadotropin in both serum and cerebrospinal fluid decreased to undetectable levels. Serum basic fetoprotein, another tumor marker, can be a tool for evaluating the clinical course following postoperative chemotherapy.
