ABSTRACT
Central nervous system germ cell tumor is a rare but important tumor in childhood brain tumors. It requires a multidisciplinary approach to increase survival and promote quality of life, and all three treatment modalities including surgery, radiotherapy and chemotherapy has its own distinct role for germ cell tumor. For germinoma, radiotherapy alone can cure the disease but, the effort to limit the long term toxicity and the proper combination of chemotherapy and radiotherapy are under investigation. Craniospinal irradiation is reserved only for the disseminated germinoma or nongerminomatous germ cell tumor (NGGCT). For germinoma, craniospinal irradiation of 20 to 24 Gy is sufficient to control microscopic disease in the spinal axis. Chemotherapy and radiotherapy composed of 30 to 40 Gy of local field radiotherapy and 20 to 24 Gy of whole ventricular irradiation are required for localized germinoma, but the proper combination of two modalities has yet to be defined. For NGGCT, both the chemotherapy and radiotherapy should be performed, and survival rate is substantially increasing with modern treatment protocols. The omission of craniospinal irradiation is being tried for the localized NGGCT in international cooperative group trials. Surgery has its role for the resection of residual disease after the treatment, and the extent of resection in NGGCT has the prognostic implication. Bifocal germ cell tumors and basal ganglia germ cell tumor have distinctive clinical course and mandate special attention. To advance clinical and biological perspectives in central nervous germ cell tumor, the cooperation and communication of the multidisciplinary specialists are essential.
