Pretty robust data confirms that HER2+/HR+ metastatic breast cancer patients should receive endocrine treatment combined with pertuzumab+trastuzumab after stopping docetaxel. The addition of ET was associated with significantly improved 5-year PFS (HR 0.58, CI 0.37–0.89, p = 0.014) and OS (HR 0.52, CI 0.31–0.90, p = 0.018), with no increase in adverse events. https://link.springer.com/article/10.1007/s10549-022-06856-1
