Docetaxel Vs. Vinorelbine in Elderly Patients With Advanced Non–Small-Cell Lung Cancer: A Hellenic Oncology Research Group Randomized Phase III Study

Abstract

Background/PurposeThis study compared front-line treatment with docetaxel or vinorelbine in elderly patients with advanced/metastatic non–small-cell lung cancer (NSCLC). Patients and MethodsChemotherapy-naive patients with inoperable stage IIIB and stage IV NSCLC who were > 65 years of age with performance status (PS) of 0-2 were enrolled. Patients were assigned to receive either docetaxel 38 mg/m2 or vinorelbine 25 mg/m2 by intravenous (I.V.) infusion on days 1 and 8 every 3 weeks. ResultsOne hundred thirty elderly patients were enrolled in the study (docetaxel n = 66 and vinorelbine n = 64 patients). The objective response rate was 12.1% and 14.1% in patients treated with docetaxel and vinorelbine, respectively (2P = .799). The median time to tumor progression (TTP) was 2.33 and 1.9 months (2P = .298) and the median overall survival (OS) was 6.07 and 3.87 months (2P = .090) in the docetaxel and vinorelbine arms, respectively. Grade 3/4 neutropenia occurred in 4.5% and 29.7% of patients in the docetaxel arm and vinorelbine arm, respectively (2P < .001). Febrile neutropenia occurred in 1.5% and 1.6% of patients in the docetaxel arm and the vinorelbine arm, respectively (2P = .950) and the use of granulocyte colony-stimulating factor (G-CSF) was more frequent in patients treated with vinorelbine (37.1% vs. 22.5%; 2P < .001). There were no deaths from toxicity. Nonhematologic toxicity was mild. ConclusionsDocetaxel has an efficacy comparable to that of vinorelbine as first-line treatment in elderly patients with NSCLC and has an acceptable toxicity profile. The trial was closed prematurely because of low accrual, thus limiting the strength of the conclusions derived.
