Oral etoposide in elderly patients with advanced non small cell lung cancer: a clinical and pharmacological study.
Seventeen elderly patients with advanced progressive non small cell lung cancer (NSCLC) were treated with oral etoposide at the daily dose of 100 mg for 14 days every 3-4 weeks with pharmacokinetic monitoring. One partial response and 6 stabilizations were documented with a median overall duration of 13 weeks (range 8-32). The median survival was 24 weeks with an apparent advantage for non-progressive patients (40 weeks vs. 18 weeks). The treatment was well tolerated especially by those patients without concomitant illness, suggesting the crucial role of a careful selection of the geriatric population. Toxicity was not related to the etoposide plasma level, but was clearly dependent on comorbidity. A geriatric assessment rather than chronological age therefore appears to be more reliable in the selection of elderly patients for clinical trials. The easy self-management, favorable toxicity profile and synergy with other compounds makes oral etoposide suitable for further clinical-pharmacological studies in elderly patients.
