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.
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.
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.
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.
Los investigadores de MD Anderson crearon TmS, un nuevo biomarcador que predice mejor la respuesta de la quimioterapia en el cáncer de mama triple negativo mediante el análisis de la actividad génica del tumor y el microambiente, mostrando una promesa para el tratamiento personalizado.
