Survival analyses in four independent cohorts. A. Fresh frozen tumor samples in the MD Anderson cohort (n = 132). B. Fresh frozen tumor samples in the Lund cohort (n = 308). C. Fresh frozen tumor samples in the TCGA cohort (n = 408). D. Formalin-fixed and paraffin-embedded samples in the MD Anderson cohort (n = 89). Left panels in each cohort show the Kaplan-Meier plots of luminal, basal, and double-negative subtypes. Right panels in each cohort show the Kaplan-Meier plots of luminal and basal cancers divided into non-p53-like and p53-like subtypes. The superficial non-invasive tumors in the fresh frozen tumor samples of the MD Anderson and the Lund cohorts were analyzed as a separate group. The survival analyses for the double-negative group were not performed in the fresh frozen tumor samples of the MD Anderson and the Lund cohorts because of the insufficient number of cases for follow-up data.
