In this issue of the Journal, Gennari et al. (1) report results of a meta-analysis of eight published studies that tested the worth of HER2 as a predictive marker of benefit from anthracycline regimens over nonanthracycline regimens. The test for treatment by HER2 status interaction yielded statistically significant results. The authors propose that it is time to stop the use of cardiotoxic anthracycline regimens for the treatment of HER2-negative breast cancer.
Most investigations of predictive markers in the adjuvant setting have suffered from a lack of statistical power because the original trials were sized to test the efficacy of the treatment on the whole cohort rather than on the subsets defined by the markers (2). Likewise, the individual studies included in the meta-analysis lacked sufficient statistical power to convincingly demonstrate an interaction between
