First-line chemotherapy for metastatic breast cancer in patients ≥75 years: A retrospective single-centre analysis

Data on chemotherapy for elderly patients with metastatic breast carcinoma (MBC) are limited. We performed a 7-year retrospective analysis of MBC patients at our institution receiving first-line chemotherapy aged >= 75 years. Of 117 patients, 103 received monotherapy (67 capecitabine, 29 vinorelbine, 5 docetaxel, 2 liposomal doxorubicin) and 14 received polychemotherapy (12 anthracycline-based, 2 vinorelbine-gemcitabine). Chemotherapy demonstrated acceptable tolerability. Median progression-free survival (PFS) and overall survival (OS) from initiation of chemotherapy were 6.2 months and 13.8 months, respectively. At 2 years, 25% of patients were alive; however, 25% died within 3 months of beginning chemotherapy. Independent prognostic factors for longer PFS were good performance status, absence of visceral disease and capecitabine treatment. Good performance status and lack of visceral disease were also significant for OS. These results suggest that palliative chemotherapy should not be systematically excluded in this setting, but should be carefully discussed as it appears to be feasible with apparent benefit in selected patients.
