Several large randomised trials completed in the mid-2000s produced overwhelming evidence that the anti-HER2 monoclonal antibody trastuzumab, administered either concomitantly or sequentially with adjuvant chemotherapy for 12 months, increases the cure rate for women with HER2-positive operable breast cancer. One surprising aspect of this success story is that the choice of 12-month treatment duration was mostly as a result of a best guess, rather than on the basis of pre-existing evidence.
