Lymph nodal infiltration pN+ (p = 0.000), tumour size of pT3-pT4 (p = 0.009), TNBC phenotype (p = 0.006), histological grade III (p = 0.007), and PR negativity (p = 0.035) were shown to predict breast cancer recurrence in univariate analysis (log-rank Mantel-Cox). The gene discussed is PGR; the disease is neoplasm.
