PGR and neoplasm: In this model, other factors associated with worse DFS included larger tumor size (HR 1.13, 95% CI 1.04–1.2, p = 0.005), increasing number of positive nodes (HR 1.1, 95% CI 1.1–1.13, p < 0.001), and undergoing lumpectomy without radiation for local therapy (HR 3.4, 95% CI 1.6–7.6, p = 0.002); PR positivity was associated with improved DFS compared to PR negativity (HR 0.4, 95% CI 0.2–0.8, p = 0.008).
