Docetaxel and vinorelbine have demonstrated Single-agent activity in breast cancer. Preclinical studies suggest potential synergy between these antitubulin chemotherapy agents. This study evaluates these drugs in combination in metastatic breast cancer. Taxane-naive patients with HER-2 negative, stage IV breast cancer without prior chemotherapy for metastatic disease, were eligible. Docetaxel (60 mg/m2) was given intravenously on Day 1, vinorelbine (27.5 mg/m2) intravenously on Days 8 and 15, and filgrastim on Days 2-21 of a 21-day cycle. The primary study outcome was one-year overall survival (OS), with secondary outcomes of progression-free survival (PFS), response rate (RR), and toxicity. Of 95 patients registered, 92 were eligible and received treatment. One-year OS was 74 % (95 % CI 64-82 %) with a median OS of 22.3 months (95 % CI 18.8-31.4 months). One-year PFS was 34 % (95 % CI 24-43 %) with median of 7.2 months (95 % CI 6.4-10.3). OS at 2 and 3 years were 49 % (95 % CI 38-59 %) and 30 % (95 % CI 21-40 %), respectively. OS was poorer for women with estrogen-receptor negative disease (n = 32) compared to estrogen-receptor positive (n = 60) (log-rank p = 0.031), but PFS was not significantly different (p = 0.11). RR was 59 % among the 74 patients with measurable disease. Grade 3 and 4 adverse events were 48 and 16 %, respectively. Grade 4 neutropenia was 12 % and grade 3/4 febrile neutropenia was 3 %. Common grade 3/4 nonhematologic toxicities were fatigue (14 %), pneumonitis (10 %), and dyspnea (9 %). The combination of docetaxel and vinorelbine is an active first-line chemotherapy in HER-2 nonoverexpressing, metastatic breast cancer. This combination is associated with significant hematologic and nonhematologic toxicity. The safety profile and expense of the filgrastim limit recommendations for routine use.
