To identify survival of the three‐mRNA model of either metastatic or nonmetastatic breast cancers on principle of “less‐gene‐possible” combination, we select one published model including two genes (HOXB13 and IL17BR) reported by Ma et al27 to compare the predictive power of prognosis in breast cancer patients from the TCGA dataset. Here, HOXB13 is linked to breast cancer.
