Abstract
Gliomas are the most common form of primary brain tumors with glioblastoma (GBM) being the most malignant. The standard therapy for newly diagnosed malignant gliomas involves maximal surgical resection, radiotherapy, and chemotherapy with a median survival of 9–14 months. The combination of RT with chemotherapeutic agents that sensitize tumor cells to the cytotoxic effects of RT has been studied in an attempt to enhance tumor control and minimize the radiation toxicity. Although such combination chemoradiation protocols have improved treatment outcomes in several human malignancies, they are still less than optimal, as the existing agents can cause undesirable toxicity. Therefore, a continuing endeavor in experimental and translational oncology research has been to identify more effective agents to augment the radiosensitivity of tumor cells. Recent efforts toward this goal have focused on molecularly targeted agents directed against certain components of intracellular signaling pathways involved in tumor growth and radioresistance.
The current chapter discusses the preclinical models in GBM radiobiology. This chapter reviews the developments that allowed basic scientists and radiation oncologists to maximize therapeutic benefits of radiation in treating GBM. The chapter also discusses past, present, and future preclinical methods in optimizing treatment for GBM.
