Interestingly, high expression of CD47 alone and combined CD47–CD68 indicated shorter RFS among luminal A tumors by multivariate assessment (HR: 3.9, p = 0.012; HR: 5.7, p = 0.004), adjusting for tumor diameter, histologic grade, and lymph node status (Tables 6 and 7). The gene discussed is CD47; the disease is neoplasm.
