ABSTRACT

BACKGROUND: In the present study, 3 cytotoxic agents were combined as front-line chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. All 3 drugs have been used in other 2-agent combinations and have been shown to be effective as first-line therapy. PATIENTS AND METHODS: Sixty-one (53 male, 8 female, median age 65 years old) out of 67 patients were evaluable for response and toxicity. Eighty percent of the patients were stage IIIB and IV and 20% were inoperable stage IIIA. In order to obviate toxicity as much as possible, paclitaxel 135 mg/m2 was combined with gemcitabine 1000 mg/m2 for the first cycle, and 2 weeks later with vinorelbine 25 mg/m2, for the second cycle; this alternate schedule was repeated every 2 weeks for 9 cycles. RESULTS: No complete responses were observed; there was a 37.7% partial response rate and stable disease in 31.1% of the patients. The median survival was 13 months and 1-year survival, 53%. Myelotoxicity involved grade 3 neutropenia in 3.3% of the patients and grade 4 in 1.6%. CONCLUSION: Adverse reactions were few in this alternate administration of paclitaxel-gemcitabine and paclitaxel-vinorelbine in NSCLC patients; in more than half of the patients there was long median and 1-year survival.

ABSTRACT

PURPOSE: Based on previous experience, we combined topotecan with paclitaxel (weekly administration) in patients with non-small-cell lung cancer (NSCLC). Our primary objective was to determine the response rate and survival and our secondary objective, the safety of the regimen. METHODS: From October 2003, until March 2005, 45 patients all with histologically or cytologically confirmed NSCLC were enrolled. All patients were chemotherapy and radiotherapy naive. Both agents were infused on day 1 of every week once for three consecutive weeks, every 28 days. Three infusions were considered as one course. The treatment plan was to give three courses (nine infusions) and then to evaluate the response. Topotecan (1.75 mg/m2) was infused for 30 min and paclitaxel (70 mg/m2) for 90 min; these doses had been established as the maximum tolerated dose in a previous phase I-II trial. RESULTS: Eighteen/45 (40%) patients responded, 2 (4.4%) complete responses and 16 (35.6%) partial responses. Twenty-one (46.7%) patients had stable disease, and 6 (13.3%) disease progression. The median duration of response was 8 months and median time to tumor progression 9 months. Grade 3 and 4 neutropenia was observed in two patients (in these two patients, the dose of both drugs was reduced by 25% and G-CSF was given), grade 4 thrombocytopenia in one patient and grade 4 anemia in one patient. CONCLUSION: This novel combination of topotecan-paclitaxel in a weekly administration rendered a 40% response rate, with very low toxicity in stages IIIA, IIIB and IV NSCLC patients.
