PURPOSE: To evaluate the efficacy and safety of the combination of gemcitabine at a low dose of 250 mg/m(2) in 6h prolonged infusion with cisplatin in chemonaive patients with advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Fifty-eight chemonaive patients with stage IIIB or IV NSCLC were included, 39 males and 19 females, with a median age 61 years (range 28-73). Thirty-four (58.6%) patients had adenocarcinoma, 18 (31.0%) squamous cell, and 6 (10.4%) others. Seventeen (29.3%) had stage IIIB and 41 (70.7%) stage IV. Treatment consisted of 250 mg/m(2) gemcitabine in a 6h infusion on days 1 and 8, and cisplatin at 75 mg/m(2) on day 2 of a 3-week cycle. A total of 219 chemotherapy cycles were administered, with a median of 4 cycles per patient (range 1-6). RESULTS: Of the 58 patients enrolled, all were evaluated for toxicity and 56 assessed for response. The overall response rate was 39.3% (95% confidence interval, 26.5-52.1%) with complete and partial responses of 3.6 and 35.7%, respectively. The median time to disease progression was 5.5 months (95% CI, 4.3-6.7 months), and median overall survival time was 10.5 months (95% CI, 8.5-12.5 months). One-year survival rate was 41.4%. Hematologic toxicity was fairly mild, and grades 3-4 hematologic toxicities consisted of neutropenia in 18.9% of patients, thrombocytopenia in 10.3%, and anemia in 6.9%. No patients required platelet transfusions, no bleeding episodes were recorded, and three patients received packed red blood cells (RBC) transfusions. The main nonhematologic toxicities included grade 3 nausea/vomiting in 27.6% of patients, grade 1-2 alopecia in 63.8%, and grade 1-2 skin rash in 17.3 %. CONCLUSIONS: Low-dose gemcitabine in 6h prolonged infusion plus cisplatin is effective in NSCLC treatment. Toxicity, especially myelosuppression, is remarkably mild.
