PgR status (P = 0.017; HR = 0.430; PgR- as a reference), residual tumor size (P = 0.003; HR = 1.690 for 2-5 cm, HR = 3.090 for > 5 cm; < 2 cm as a reference), residual lymph node involvement (P = 0.014; HR = 0.843 for 1-3 positive node, HR = 2.624 for ≥4 positive node; 0 positive node as a reference), and Ki-67 (P = 0.015; HR = 2.245; < 15% as a reference) were independent prognostic variables for RFS. The gene discussed is PGR; the disease is neoplasm.
