Résumé

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 = 0.0001) 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.
