ETOPOSIDE (VP-16) AND CISPLATIN AT MAXIMUM TOLERATED DOSE IN NON-SMALL-CELL LUNG-CARCINOMA - A CANCER AND LEUKEMIA GROUP-B STUDY

A multi-institutional cooperative group trial was undertaken by the Ca ncer and Leukemia Group B (CALGB) to evaluate the efficacy of the comb ination of cisplatin and intravenous etoposide for the treatment of me tastatic or recurrent non-small cell lung cancer (NSCLC), The doses us ed were those previously determined to be the maximally tolerated dose of this drug combination, Forty patients were entered into the trial, 37 of whom were eligible for evaluation, Cisplatin (35 mg/M2/day for 3 days) and etoposide (200 mg/M2/day for 3 days) were administered eve ry 28 days for a planned 6 cycles of therapy, Sixteen of 37 evaluable patients (43%) responded to therapy, Myelosuppression was the dominant toxicity, with 89% of the patients experiencing grade 4 neutropenia, and nearly half grade 3 or 4 thrombocytopenia, Median survival was 8.5 months, with 30% of the patients alive at 1 year and 10% alive at 2 y ears. Malaise, fatigue, and peripheral neuropathy were the other major toxicities. The combination of etoposide at the dose of 200 mg/M2/day for 3 days and cisplatin at 35 mg/M2/day for 3 days is a highly poten t combination against metastatic non-small cell carcinoma.
