Abstract

PURPOSE:

A phase II randomized trial was conducted in patients with advanced non-small-cell lung cancer (NSCLC) to determine if the combination of moderate-dose cisplatin and carboplatin was active (primary end point) and could avoid the long-term limiting (renal, auditive, neurologic) toxicity of high-dose cisplatin, which prevents prolonged administration (secondary end point).

PATIENTS AND METHODS:

One hundred twenty-one patients, registered between April 1990 and September 1991, were randomized to receive high-dose cisplatin (120 mg/m2 intravenously [IV] on day 1) or a combination of moderate-dose carboplatin (200 mg/m2 IV on day 1 and moderate-dose cisplatin (30 mg/m2 IV on days 2 and 3). One hundred nine patients were eligible: 56 in the cisplatin arm and 53 in the combined arm; 52 and 47, respectively, were assessable for response. All had stage IV disease (or stage IIIB with pleural effusion) and none had received prior chemotherapy.

RESULTS:

There was a 23% objective response rate to cisplatin (23% of the eligible patients) and a 22% response rate to cisplatin plus carboplatin (21% of the eligible patients). The overall survival rate was not significantly different between the two study arms, but responders in the combined arm survived significantly longer than those in the high-dose cisplatin arm (respective median survival durations, 66 and 30 weeks). Although there was no difference between the arms for alopecia, emesis, and leukopenia, the combined arm was significantly associated with more thrombocytopenia (although rarely severe) and, more importantly, with less renal (19% v 36%), auditive (4% v 16%), and neurologic (0% v 16%) toxicity of any grade.

CONCLUSION:

The regimen combining moderate-dose cisplatin and carboplatin was active against advanced NSCLC and significantly less toxic than high-dose cisplatin.
