Outcomes for patients with glioblastoma have improved with the addition of temozolomide (TMZ) chemotherapy to radiation therapy followed by adjuvant TMZ for up to 1 year. Patients often wish to continue chemotherapy after the standard 1-year course. Whether to continue or to stop TMZ is a complex and stressful decision for the patient and family, and the decision should be based on a discussion of the known risks and benefits of each choice.
