Multivariate analysis according to Cox's model demonstrated that tumor stage (II: (relative risk (RR) (confidence interval (CI) = 1.8(0.7–4.5); III: 4.6(1.8–12.0); p = 0.003) and PgR status (positive: 0.4(0.2–0.8), p = 0.011) were significant and independently associated with distant relapse-free survival. The gene discussed is PGR; the disease is neoplasm.
