PGR and neoplasm: The other clinicopathologic factors significantly associated with disease-free interval were the pathologic tumor size (pT ≥ 20 mm versus < 20 mm: p = 0.025, HR = 1.51), pathologic nodal stage (pN+ versus pN0–pNX: p = 0.015, HR = 1.56), distant metastasis (M1 versus M0–MX: p < 0.0001, HR = 5.35), lymphovascular invasion (LVI+ versus LVI–: p = 0.0002, HR = 1.97), and PR positivity (PR ≥ 10% versus PR < 10%: p = 0.043, HR = 0.48).
