A phase II study of irinotecan plus cisplatin for patients with advanced stage IIIB or IV NSCLC previously treated with nonplatinum-based chemotherapy.
BACKGROUND
Irinotecan (1) and cisplatin (P) are active chemotherapy agents with clinical synergy in non-small-cell lung cancer (NSCLC). We evaluated the efficacy of IP regimen as a salvage treatment of patients with NSCLC that progressed after nonplatinum-containing regimen(s).


METHODS
Eligibility required histologically confirmed NSCLC, bidimensionally measurable disease, ECOG PS 0-2, and progressive disease after nonplatinum-based chemotherapy. Treatment consisted of I (65 mg/m2) and P (30 mg/m2) i.v. on Days 1 and 8 of a 21-day cycle, for a maximum of 6 cycles. An informed consent was obtained from all patients.


RESULTS
Between August 2002 and May 2004, 32 patients with median age of 56 years (range, 42-74) were enrolled. Twenty-four (75%) patients were men, and 28 (88%) had ECOG PS 0 or 1. Twenty-five patients had adenocarcinoma and 6 had squamous-cell carcinoma. All patients were evaluated for response and toxicity, and the response rate was 40.6%. After a median follow-up of 18.5 months, the median survival time was found to be 9.3 months, with a 1-year survival rate of 43.8%. Toxicities were moderate and manageable, with 47% G3 and 9% G4 neutropenia, 19% G3 diarrhea, and 22% G3 asthenia. There was no G4 nonhematologic toxicity.


CONCLUSIONS
The irinotecan and cisplatin combination is an active and well-tolerated regimen for the patients with advanced NSCLC that progressed after nonplatinum-containing regimen(s).
