Review
[Recent advances in targeted therapies in the treatment of HER2-positive metastatic breast cancer].
Metastatic breast cancer (MBC) is an incurable disease. The goal of treatment is mainly palliative to improve quality of life by the control of disease (in terms of disease free survival [DFS]) as long as possible, and to treat symptoms with fewer side effects. The gene c-erb B2 or neu or HER2 is amplified in 20-25% of breast cancers. ⋯ After disease progression with trastuzumab-based therapy, rechallenging Trastuzumab in combination with chemotherapy is a reasonable option. After a second progression with trastuzumab, a combination based on lapatinib plus Capecitabine (or other chemotherapy if Capecitabine was previously used) should be proposed; the combination based on lapatinib and trastuzumab is reasonable. Inclusion in clinical trials must continue to improve outcomes for our patients.
