Isotretinoin maintenance therapy for glioblastoma: a retrospective review.

Objectives: The current standard treatment of glioblastoma includes maximal safe surgical resection, radiation, and temozolomide. Although isotretinoin has been used for maintenance therapy to delay tumor recurrence, this approach has not been proven to be effective. The objectives of the study are to compare the overall survival, progression-free survival and tolerability of isotretinoin maintenance therapy in patients who received isotretinoin maintenance therapy to patients who did not receive this treatment.

Atypical teratoid/rhabdoid tumors in adults: a case report and treatment-focused review.

Unlabelled: Atypical teratoid/rhabdoid tumor is predominantly a childhood tumor and has only been rarely reported in adults; therefore, treatment regimens are often extrapolated from the pediatric experience. Typically, children are treated with craniospinal radiation therapy which is often followed by systemic chemotherapy. Employing pediatric regimens to treat this tumor in adult patients poses a particular risk for myelosuppression, as the prescribed doses in pediatric protocols exceed those tolerated by adults, and conventional craniospinal radiation can be associated with prolonged myelotoxicity and a depletion of the bone marrow reserve in vertebrae of adults.

Seizure risk in brain tumor patients with conversion to generic levetiracetam.

Breakthrough seizure activity has been reported with conversion from brand name to generic anticonvulsants. This has prompted several organizations to support physician notification of generic substitution and patient consent. Recently, a generic formulation of levetiracetam has become available.
