A multicenter phase II study of docetaxel and carboplatin combination as front-line treatment in advanced non-small cell lung cancer.

BACKGROUND: To evaluate the efficacy and safety of docetaxel in combination with carboplatin as first-line treatment of patients with inoperable, locally advanced or metastatic non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy-naive patients with stage IIIB and IV NSCLC, age < 75 years, performance status (WHO) 0-2, were enrolled onto the study. Docetaxel was given at a dose of 100 mg/m2 over an 1-hour i.v. infusion. Carboplatin dosed to an area under the time-concentration curve (AUC) of 6 mg/ml.minute, using the Calvert's formula, was administered over a 30-minute i.v. infusion. The regimen was repeated every 3 weeks. RESULTS: Thirty-eight patients received a total of 155 chemotherapy cycles (median 4 cycles/patient). All patients were assessable for toxicity and 34 for response. There was one (2.6%) complete and nine (23.7%) partial responses; in an intention-to-treat analysis the overall response rate was 26.6% (95% CI: 12.3%-40.3%). The median duration of response was 7 months (range: 3-29), the median time to tumor progression 7 months (range: 3.5-31), and the median overall survival 9 months (range: 0.5-31.5). The probability for 1-year survival was 44%. Grade 3-4 neutropenia was the main hematological toxicity of the regimen occurring in 19 (50%) patients. Four (10.5%) neutropenic episodes were complicated with fever but there was no septic death. Non-hematological toxicity was generally mild. CONCLUSION: These results indicate that the docetaxel-carboplatin combination is a relatively active and well-tolerated front-line regimen for the treatment of patients with advanced or metastatic NSCLC.

Oxaliplatin with high-dose leucovorin and infusional 5-fluorouracil in irinotecan-pretreated patients with advanced colorectal cancer (ACC).

The purpose of this study was to evaluate the efficacy and tolerance of the bimonthly administration of oxaliplatin in combination with high-dose leucovorin and infusional 5-fluorouracil (5-FU) (FOLFOX2 regimen) in patients with advanced colorectal cancer (ACC) who did not respond or whose disease progressed within 3 months after front-line treatment with CPT-11-containing regimens. Forty-one patients with ACC who did not respond or whose disease progressed after front-line treatment with CPT-11 + 5-FU/leucovorin were enrolled. Oxaliplatin was administered at the dose of 100 mg/m2 on day 1 as a 2-hour infusion simultaneously but through different lines with leucovorin (500 mg/m2 on days 1 and 2); 5-FU was given at the dose of 1,750 mg/m2/d as a 22-hour continuous intravenous infusion on days 1 and 2. The regimen was repeated every 2 weeks. In an intention-to-treat analysis, complete response was achieved in one (2.4%) and partial response in six (14.6%) patients (overall response rate: 17%; 95% CI: 5.56-28.59%); stable disease and progressive disease were observed in 15 (36.6%) and in 19 (46.31%) patients, respectively. The median duration of response and the median time to tumor progression were 6 and 8.5 months, respectively. The median overall survival was 12 months and the probability for 1-year survival was 42.9%. Grade III/IV neutropenia occurred in 17 (41%) patients and febrile neutropenia developed in one of them (2%). There was no treatment-related death. Peripheral neuropathy greater than or equal to grade II occurred in 24 (58%) patients. Other toxicities were relatively mild. The bimonthly administration of oxaliplatin in combination with high-dose leucovorin and 48-hour continuous infusion of 5-FU is a relatively active and well-tolerated regimen for patients with ACC resistant or refractory to CPT-11 + 5-FU (continuous infusion)/leucovorin.
