Intrinsic subtyping enables fine-tuned prognosis, prediction of tumor behavior

A study shows the intrinsic subtyping of breast cancer by means of a genomic test as the most important prognostic factor in advanced or metastatic hormone-sensitive breast cancer. Findings show that the genomic classification of tumors — the molecular subtyping of primary tumors, can predict the evolution of patients from the onset of metastasis and that this cancer intrinsic classification can better guide treatment decisions in the first-line metastatic setting.
