Results: On multivariable analysis, we found statically significant differences in Oncotype DX recurrence scores according to age (60–69 vs. 18–49, p=0.01), ER/PR status (PR-positive vs. PR-negative, p < 0.0001), histology (other vs. ductal, p=0.004), and tumor size (2–5 cm vs. 0-1 cm, p=0.0003). The gene discussed is PGR; the disease is neoplasm.
