11 years’ follow-up of trastuzumab after adjuvant chemotherapy in HER2-positive early breast cancer: final analysis of the HERceptin Adjuvant (HERA) trial. Lancet 2017; 389: 1195–1205.

Conclusion

The study included 5099 women followed for a median of 11 years. One year of trastuzumab improved disease-free (hazard ratio 0.76, 95 per cent confidence interval 0.68 to 0.86) and overall survival (0.74, 0.64 to 0.86). There was no advantage in the second year of trastuzumab.
