Chemotherapy with cisplatin and teniposide for cerebral metastases in non-small cell lung cancer.

Twenty-three patients with brain metastases from non-small cell lung cancer (NSCLC) (median age 62 years, Karnofsky PS 50-100) were treated with cisplatin (100 mg/m2, day 1) and teniposide (80 mg/m2, days 1, 3 and 5) every 3 weeks. Response was evaluated by contrast-enhanced brain CT every two to three cycles of treatment. The objective response rate of brain metastases was 35% (8/23); three patients achieved complete response (CR) and five partial response (PR). The median response duration was 24 weeks for CR patients and 32 weeks for PR patients. The median survival was 21 weeks overall and 45 weeks for responding patients. Grade 3/4 leukocytopenia and thrombocytopenia were seen in 28 and 9%, respectively. Two patients died from infections while in neutropenia. Cisplatin and teniposide seems an active regimen against brain metastases in NSCLC. These data may indicate the need for reconsideration of the role of chemotherapy for brain metastases of NSCLC.
