ABSTRACT: 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).
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).
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 %.
Low-dose gemcitabine in 6h prolonged infusion plus cisplatin is effective in NSCLC treatment. Toxicity, especially myelosuppression, is remarkably mild.

ABSTRACT: The objective was to evaluate the efficacy and toxicity of leucovorin plus 5-fluorouracil combined with oxaliplatin (modified FOLFOX regimen) every 2 weeks on previously untreated advanced colorectal cancer patients in the Chinese population. Fifty-one inpatients were enrolled to receive 85 mg/m oxaliplatin intravenously over a 2- h period on day 1, together with 400 mg/m2 leucovorin over 2- h, followed by a 46-h infusion of 5-fluorouracil at 2600 mg/m2 every 2 weeks. Treatment was given until progression or unmanageable toxicity ensued. In all, 51 patients received three or more oxaliplatin doses and a median of nine treatment cycles (range 3-16 cycles). Of the 51 eligible patients, two complete responses and 22 partial responses were observed for an overall response rate of 47.0% (95% confidence interval 35-64%). Median progression-free survival was 7.7 months (95% confidence interval 6.8-8.6) and median overall survival was 15.0 months (95% confidence interval 13.1-16.9). Toxicities were mild: five patients (9.8%) reported grade 3-4 neutropenia, 33 patients (64.8%) experienced grade 1-3 neurotoxicity and only six patients (11.8%) experienced grade 3 neurotoxicity. The leucovorin plus 5-fluorouracil combined with oxaliplatin (modified FOLFOX) regimen is active and well tolerated in patients with previously untreated advanced colorectal cancer in the Chinese population.

ABSTRACT: Gemcitabine combined with cisplatin has been taken as the front-line regimen for patients with advanced non-small-cell lung cancer (NSCLC). The routine use of gemcitabine is intravenous injection of a dose of 1,000 mg/m(2) within 30 minutes on days 1 and 8, and the treatment is repeated every 3 weeks. This study was to evaluate the efficacy and safety of 6-hour continuous infusion of low dose of gemcitabine plus cisplatin for patients with advanced NSCLC.
Forty-eight patients with measurable stage III B/IV NSCLC and without chemotherapy were enrolled. All of them received 6-hour continuous infusion of gemcitabine 250 mg/m(2) on day 1 and 8 plus cisplatin 75 mg/m(2) on day 2-4 for more than 2 cycles. The cycle was repeated every 3 weeks.
All 48 patients were evaluated for toxicity and 46 for response. The overall response rate was 32.5% (completed and partial response rates were 2.2% and 30.3%, respectively). The median time to progression was 5.1 months, median survival time was 10.2 months; and 1-year survival rate was 36.6%. The main hematologic toxicity consisted of 60.4% neutropenia, 39.5% thrombocytopenia. Grade III-IV neutropenia and thrombocytopenia were 20.8% and 12.5%, respectively.
Six-hour prolonged infusion of low dose gemcitabine combined with cisplatin is a relatively safe and effective regimen for patients with advanced NSCLC.
