title: Chemotherapy with cisplatin for AFP-secreting germ-cell tumors of the central nervous system.
abstract: Therapeutic results in 17 cases of alpha-fetoprotein (AFP)-secreting tumors of the central nervous system are reported. Twelve of the patients were male and five female. The patients' ages ranged from 5 years to 25 years (mean 13.6 years). The tumors originated in the pineal region in 10 cases, in the suprasellar region in four cases, and in both regions in one case; of the other two tumors, one originated in the basal ganglia and one in the sacrococcygeal region. Extraneural metastases or subarachnoid dissemination occurred in seven cases. Increased AFP titer in the serum or cerebrospinal fluid was verified in 13 cases. The patients were divided into two groups: those treated before (Group A) and those treated after (Group B) the introduction in 1980 of cisplatin as a chemotherapeutic agent. All seven Group A patients died, even after extensive therapy consisting of surgery, radiotherapy, and chemotherapy (ACNU or adriamycin) in some of the cases. The mean survival time following diagnosis for Group A was 23.7 months. Six of the 10 Group B patients died an average of 25.8 months after diagnosis; however, the other four were still alive and well an average of 25.3 months after diagnosis. The tumors responded well to chemotherapy consisting of cisplatin either alone or combined with bleomycin and vinblastine. The initial response rate to treatment in Group B was 100% and five cases had a complete remission, verified by computerized tomography or the serum AFP level. Once the tumor recurred, the response to cisplatin was markedly decreased. It is suggested that an effective therapy must still be sought for recurrent tumors.
