flag MD Anderson researchers created TmS, a new biomarker that better predicts chemo response in triple-negative breast cancer by analyzing tumor gene activity and microenvironment, showing promise for personalized treatment.

flag Researchers at MD Anderson Cancer Center have developed a new biomarker, TmS, which improves predictions of chemotherapy response in triple-negative breast cancer by accounting for gene expression changes within tumors and their microenvironments. flag Tested on 575 ethnically diverse patients, TmS outperformed existing models in distinguishing high- and low-prognosis groups and revealed differences in tumor microenvironments between Western and Asian patients, suggesting potential for personalized treatments. flag The tool integrates tumor cell ratios and RNA activity dynamics, offering a more accurate, accessible method for patient stratification, though further validation is needed before clinical use.
