Locoregional approaches to therapy with gliomas as the paradigm.

Most malignant gliomas recur locally, despite the fact that these tumors are usually found to be diffusely infiltrating on pathologic studies. Thus, efforts have concentrated on local disease control as an initial step to improve the prognosis of these patients. This review discusses the most recent studies on locoregional approaches in therapy for this poor-prognosis neoplasm. Emphasis is placed on the radiotherapeutic and combined modality (radiotherapy and chemotherapy) approaches reported during the past year.
