Gemcitabine and vinorelbine in the second-line treatment of nonsmall cell lung carcinoma patients: a minnie pearl cancer research network phase II trial.
BACKGROUND
Second-line chemotherapy for patients with nonsmall cell lung carcinoma has been ineffective due to the lack of activity of older agents following platinum-based therapy. This Phase II trial evaluated the feasibility, toxicity, and efficacy of two active new agents, gemcitabine and vinorelbine, used in combination as second-line therapy for patients with nonsmall cell lung carcinoma.


METHODS
Patients with advanced nonsmall cell lung carcinoma who had progressive disease after previous chemotherapy or combined-modality therapy were eligible for this trial. All patients received vinorelbine 20 mg/m(2) followed by gemcitabine 1000 mg/m(2) on Days 1, 8, and 15 of each 28-day cycle. Patients were reevaluated for a response after two treatment courses: responding patients and those with stable disease received a maximum of six courses. Fifty-five patients were treated between January 1998 and November 1998; 47 patients (85%) had previously received both a taxane and a platinum agent.


RESULTS
Objective responses were seen in 9 of 50 evaluable patients (18%), including 8 partial responses and 1 complete response. Twenty-four additional patients (48%) had either minor response or stable disease. The median time to progression for patients with objective response or stable disease was 5 months. The median survival was 6.5 months with an actuarial 1-year survival of 20%. The treatment was well tolerated with uncommon nonhematologic toxicity and no alopecia. Grade 3 neutropenia and thrombocytopenia occurred in 27% and 22% of patients, respectively, but Grade 4 neutropenia was uncommon (occurring in 9% of patients) and only 4 patients required hospitalization for treatment of neutropenia and fever.


CONCLUSIONS
The combination of vinorelbine and gemcitabine is active and well tolerated as second-line therapy for patients with advanced nonsmall cell lung carcinoma. This regimen merits further evaluation as a first-line therapy for patients with this disease.
