Disease-free survival as a surrogate for overall survival in HR+/HER2 − early breast cancer: a correlation analysis
Overall survival (OS) is a universally accepted measure of clinical benefit; however, prolonged follow-up is needed to observe sufficient events. Disease-free survival (DFS) has been widely adopted as a primary endpoint for early breast cancer (EBC) trials, as follow-up is comparatively shorter. Here, we present an analysis evaluating DFS as a surrogate for OS for adjuvant treatment of hormone receptor –positive/human epidermal growth factor receptor 2–negative (HR+/HER2−) EBC.
