Single-center retrospective study of clinical features and survival outcomes of breast cancer with intermediate ER expression
Prof. Ioannis Voutsadakis
A retrospective study at Northern Ontario School of Medicine (Sudbury) compared clinical features and survival outcomes among breast cancer patients with high, intermediate, and low ER expression. Patients with intermediate ER expression presented at younger age than patients with high-ER cancers, as well as a more advanced stage and higher grade. Mastectomy was the surgical method of resection more commonly in ER-intermediate tumors than in ER-high tumors. The overall survival in the ER-intermediate and ER-low groups was worse than in the ER-high group.
