It was higher in younger patients (P=0.0384), smaller tumors (≤2.0 cm, P<0.0001), IDC (P<0.0001), early-stage cancers (P<0.0001), lymph node-positive patients (P<0.0001), and PR-positive patients (P<0.0001), suggesting its involvement in tumor invasiveness and metastasis. Here, PGR is linked to neoplasm.
