BackgroundA combination regimen comprised of docetaxel, gemcitabine, and granulocyte-colony stimulating factor (G-CSF) was studied in patients with advanced nonsmall cell lung carcinoma (NSCLC) to determine its antitumor efficacy and tolerance.MethodsThirty-four patients with advanced measurable NSCLC (3 patients with Stage IIIB and 31 patients with Stage IV disease) were treated with an intravenous combination chemotherapy regimen comprised of docetaxel, 80 mg/m(2), on Day 1 and gemcitabine, 1000 mg/m(2), on Days 1 and 10; G-CSF, 5 microg/kg, was administered subcutaneously between Days 2 and 8. Treatment cycles were repeated every 3 weeks. All patients were evaluable for toxicity and response assessment. A total of 163 courses was administered.ResultsObjective tumor response was noted in 17 patients (50%; 95% confidence interval, 32. 5-67.5%), including 2 complete responses (6%) and 15 partial responses (44%). There was no change in 10 patients (29%) and 7 patients developed progressive disease. The median duration of response was 6.5 months (range, 3-15 months) and the median time to disease progression for all patients was 6.8 months (range, 1.8-18 months). The median overall survival time was 13.0 months (range, 2. 5-23+ months) with a 1-year survival rate of 55.8%. Myelosuppression was the most frequently encountered adverse reaction, although World Health Organization Grade 3 or 4 leukocytopenia and/or granulocytopenia occurred in only 18% and 24% of patients, respectively. Other toxicities generally were mild to moderate, and always fully reversible.ConclusionsWith a response rate of 50% and a median survival time of 13 months, the drug combination described in the current study appears to have significant activity against advanced metastatic NSCLC. Due to its fairly good tolerance and ease of administration, further investigation of this regimen appears warranted.Copyright 2000 American Cancer Society.
