[Chemo-radiotherapy for malignant brain tumors].

Abstract

I) Malignant gliomas: Randomized clinical trials conducted in the USA showed that radiotherapy plus chemotherapy with nitrosoureas offered a long-term survival advantage to patients younger than 60 years old with malignant gliomas. Combination chemotherapy, such as procarbazine/CCNU/vincristine (PCV) must be tested further, and intra-arterial chemotherapy with nitrosoureas offered no survival advantage. Combination chemotherapy with PCV showed efficacy for patients with anaplastic oligodendroglioma and anaplastic oligoastrocytoma. II) Medulloblastoma: The addition of chemotherapy to radiotherapy improved the survival of patients with poor risk medulloblastoma, and may reduce the required craniospinal radiation dose in patients with good risk medulloblastoma. III) Primary CNS lymphoma (PCNSL): Combination of chemotherapy with high-dose MTX and radiotherapy improved survival of patients with PCNSL; however, the neurotoxicity produced by this treatment modality is a serious problem in older patients. IV) Intracranial germ cell tumors: The addition of chemotherapy to radiotherapy may produce long term survival with good quality of life in patients with germinoma. Neoadjuvant therapy consisting of chemotherapy and radiotherapy followed by complete surgical excision improved survival of patients with intracranial nongerminomatous germ cell tumors.
