Background: Whenever possible, treatment of breast cancer should be performed in an outpatient setting, but only few data about patients being treated exclusively on an outpatient basis are available.
Patients and methods: A retrospective analysis was performed in 90 unselected patients who were treated consecutively in our oncology group practice between 6/95 and 8/99.
Results: Median age at detection of metastases was 55 years (30-90) and performance status ranged from 0 to 2. 83 patients (92.2%) received chemotherapy, 7 (7.8%) received endocrine therapy only. CMF was used in 27.7%, anthracyclines in 71.1% and taxanes in 43.3%. 855 chemotherapy cycles were performed and the observed toxicity was mild. Reversible grade 3 and 4 hematotoxicity was seen after 27 cycles (3.2%). Neurotoxicity or mucositis grade 3 and 4 were seen in 6 patients (6.6%). Therapy-associated hospitalization occurred in 1 patient thrice due to febrile neutropenia. Complete remissions were seen in 5 patients (5.6%) during first-line therapy. Median survival of the whole cohort until the end of the follow-up period (2/03) was 28 months (2-259). Overall survival after 1, 2, 3 and 5 years was 83, 56, 33 and 18% respectively. 50% could die at home.
Conclusions: Treatment of metastatic breast cancer can be performed with minimal toxicity and a high patient acceptance in the outpatient setting. Overall survival and median survival are comparable to historical results achieved in specialized academic hospitals. Hospitalization could be avoided in the majority of patients and half of them could die at home.
