Medical Therapy
Specific genetic or chromosomal abnormalities involving deletions of 1p and 19q have been identified for a subset of oligodendroglial tumors, which have a high response rate to lomustine, procarbazine, and vincristine (PCV) therapy. Other CNS tumors are associated with characteristic patterns of altered oncogenes, altered tumor-suppressor genes, and chromosomal abnormalities. As noted above, familial tumor syndromes with defined chromosomal abnormalities are associated with gliomas. (Refer to the Classification section of this summary for more information.)
Chemotherapy may prolong survival in patients with some tumor types and has been reported to lengthen disease-free survival in patients with gliomas, medulloblastoma, and some germ cell tumors. Local chemotherapy with a nitrosourea applied to a polymer placed directly in the brain during surgery has been shown to be a safe modality and is under clinical evaluation.
