Five years of stable disease with maintenance therapy using bevacizumab and tamoxifen in a patient with metastatic breast cancer.

Bevacizumab and Tamoxifen are valid therapeutic options for metastatic breast cancer (mBC) patients. In this report, we describe a 47 year old woman with mBC successfully treated with a maintenance therapy with Bevacizumab+Tamoxifen. A maintenance approach using 2 different drugs with different targets and mechanism of action, such as anti-angiogenic and anti-hormonal treatment is particularly intriguing because they affect different pathways involved in mBC progression. Further studies including a large number of patients are needed, in order to select women who could benefit from this maintenance approach.
