About

The management of glioblastoma in elderly patients with poor performance status (KPS<70) is unsettled. This single arm phase 2 trial trial was designed to evaluate the efficacy and safety of temozolomide alone in this population

Full description

This trial was conducted to evaluate the efficacy, in terms of survival and quality of life, and safety of up-front temozolomide in elderly GBM patients with poor performance status.

Patients of 70 years of age or older were eligible to participate in this prospective non-randomised multicentric phase II study if they had newly diagnosed and histologically proven glioblastoma on the basis of the WHO classification, and a postoperative KPS between 30 and 60.

Treatment consisted of temozolomide 150-200 mg/m2/day for 5 consecutive days every 4 weeks for a maximum of 12 cycles or until disease progression or prohibited toxicity.

Patients were assessed at least every month by means of physical and neurological examinations, KPS, health-related EORTC questionnaires (QLQ-C30 and QLQ-BN20), and MMSE. Complete blood counts and blood chemistry were drawn before each temozolomide cycle; the earlier were also checked every 10 days during the first 2 cycles and every 2 weeks afterwards. CT or MRI studies were repeated every 2 months.
