Received Accepted Published The present study was conducted in patients with metastatic breast cancer. Its aim was to identify the factors which influence progression -free survival PFS and overall survival OS after the first line of chemotherapy in patients with positive tumour hormone receptor status. The patients with early disease progression during first-line chemotherapy were not included. In total 560 patients who achieved a stable disease or a response to first-line chemotherapy were studied. The factors identified to improve the duration of PFS or OS in multivariate analysis were number of metastatic sites p .01 p .01 metastatic sites p .02 p .04 Disease free interval p .001 p .0001 previous hormonal therapy p .03 p ns response to first line chemotherapy p .0001 p and an administration of maintenance hormonal therapy p .0001 p .001 . The major impact obtained by maintenance hormonal treatment after first-line chemotherapy in this study seems to indicate that this strategy should be recommended in patients with an ER or PgR positive tumour. Key words Breast cancer maintenance treatment chemotherapy Metastatic hormonotherapy. INTRODUCTION
