Trastuzumab is used for the adjuvant (postoperative) treatment of (HER2)-positive early breast cancer. The duration of treatment is set at one year. The goal of our study was to examine the effective duration of trastuzumab treatment in routine clinical practice. ⋯ Half of the patients completed the 52-week treatment of trastuzumab after surgery for early breast cancer. Trastuzumab was well-tolerated and the rate of discontinuation due to cardiotoxicity was low, compared to published results.
