Excerpt:
In patients whose tumors showed TOP2A alterations (either amplifications or deletions), treatment with CEF was statistically significantly superior to treatment with CMF in terms of RFS (adjusted hazard ratio [HR] = 0.35, 95% confidence interval [CI] = 0.17 to 0.73, P = .005) and OS (adjusted HR = 0.33, 95% CI = 0.15 to 0.75, P = .008)....TOP2A gene alterations (amplifications or deletions) are associated with an increase in responsiveness to anthracycline-containing chemotherapy regimens.
