A study of the combination of gemcitabine hydrochloride (LY188011) and cisplatin in non-small-cell lung cancer: 3-week schedule.

Abstract

BACKGROUND:

It has been reported that the combination of gemcitabine (LY188011; GEM) and cisplatin (CDDP) in a 4-week schedule showed a high response rate for patients with non-small-cell lung cancer (NSCLC), but GEM could not be administered on day 15 because of increased myelosuppression in many patients. The present study was performed to evaluate the efficacy and safety of GEM and CDDP in a 3-week schedule.

METHODS:

Patients with unresectable NSCLC without prior chemotherapy were enrolled. We administered 1000 mg/m2 of GEM on days 1 and 8, and 80 mg/m2 of CDDP on day 1. The feasibility of the combination therapy was confirmed in 8 patients, and then 20 more patients were enrolled, to evaluate the efficacy and safety of this combination therapy for all 28 patients.

RESULTS:

The response rate was 42.9% (12/28) and the median survival time was 12.6 months. Neutropenia, leukopenia, anemia, thrombocytopenia or lymphocytopenia of grade 3 or higher were observed as hematological toxicity, and anorexia, nausea, fatigue, or vomiting of grade 3 were the nonhematological toxicities, but most of these toxicities were of grade 2 or less. For GEM and CDDP, 89% and 91% of the scheduled doses, respectively, were administered.

CONCLUSION:

This is the first study of the combination of GEM and CDDP with a 3-week schedule in Japan, and the results showed a low level of myelosuppression, high dose intensity, and high response rate, similar to the results reported in other countries. Accordingly, the combination of GEM and CDDP with a 3-week schedule may be a promising regimen for the treatment of NSCLC in Japan.
