Treatment And Outcome Of Brain Metastasis As First Site Of Distant Metastasis From Breast Cancer
Published 2004 · Medicine
Twenty-eight consecutive patients with breast cancer were analyzedwho presented with a single brain metastasis asfirst site of distant metastasis. The response tosurgery with postoperative radiation therapy (RT) (9 patients)and to non-surgical therapy as first-line treatment was100% and 89% respectively with a significant differencein median recurrence-free intervals of 23 months andof 5 months respectively (p=0.033). Retreatmentof a local relapse by surgery (± RT,± chemotherapy) or by non-surgical treatment resulted ina response in 6 of the 7 operatedpatients and in 5 of the 6 non-operatedpatients with a median duration of response of7 months (range 2–20 months) and of 3months (range 2–4 months) respectively. The overall mediansurvival of the 28 patients with a singlebrain metastasis was 16 months (range 2–39 months).The median survival in the primarily operated patientswas 23 months, in the primarily not-operated group10 months, and in the never-operated group 9months. In comparison, the response to non-surgical treatmentin 20 consecutive patients who presented with multiplebrain metastases as first site of distant metastasiswas 55% with a median recurrence free intervalof 4 months. The median survival in thisgroup was 4 months, which was significantly shorterthan survival of patients with single brain metastasis(p=0.0036). These results suggest that breastcancer patients with a single brain metastasis asfirst presentation of relapse constitute a specific subgroupwith a favorable response to treatment and along survival especially if they can be treatedby surgery with postoperative RT.
