[Malignant non-seminomatous germinal tumors of the ovary. Experience of the French Society of Pediatric Oncology. 64 cases].
Ovary seminomatous malignant germ cell tumours are a particular histopathologica entity. The presence of yolk salk tumor or choriocarcinoma is respectively correlated with elevation of alpha FP or beta hCG. This markers elevation permits to assess diagnosis, appreciate response to treatment, and detect relapses. The study of 64 patients registered in two successive S.F.O.P. protocols (TGM 85-TGM 90) precise indications of surgery, platin-based chemotherapy and results. Malignant non seminomatous germ cell tumors are separated in not secreting pure immature teratoma and secreting malignant germ cell tumours. Surgery is essential for treatment of not secreting pure immature teratoma. Secreting germ cell tumors are very chemosensitive and surgery must be as conservative as possible in all cases even metastatic tumour or relapse. If markers are normalized second-look surgery of secreting malignant germ cell tumours is only necessary in case of evident residual tumour. However in case of initial chemotherapy, resection of a pathological ovary is always performed at the end of treatment. These tumours have a good prognosis: 5-years overall survival and disease-free survival are 85%.
