In that regard, we need biomarker tools to guide treatment escalation and de-escalation for many types of breast cancer, in particular, HER2-positive and triple-negative breast cancers, which can be difficult to treat. Some of our previous studies have already shown the prognostic and predictive ability of B cell-related signatures in triple-negative breast cancers. It would not surprise us if a similar analysis in triple-negative breast cancer found the same results as those in this current study of HER2-positive cancers.” Credit UNC Lineberger Comprehensive Cancer Center Usage Restrictions None License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
