In this study, we aimed to compare the time to development of brain metastasis, survival times after brain metastasis and overall survival (OS) times in patients with metastatic breast cancer (MBC) treated with and without trastuzumab.
We evaluated 16 patients diagnosed as MBC with c-erbB-2 positive and developed brain metastasis during follow-up. Seven patients were treated with trastuzumab containing regimen before development of brain metastasis while 9 patients were treated with regimen containing no trastuzumab. Median time to development of brain metastasis after detection of first metastasis and median OS time after having MBC was found to be longer in patients treated with trastuzumab (p=0.03 and p=0.0003, respectively). Although patients treated with trastuzumab had longer survival after development of brain metastasis, it did not have statistical significance (p=0.19). By using trastuzumab in the treatment, control of systemic disease in patients with MBC is more feasible and survival rates are remarkably longer.
