ERBB2 and metastatic malignant neoplasm in the lymph nodes: Such CD47-HER2-associated recurrent rates also agreed with a worse prognosis in BC patients with a dual enhancement of CD47 and HER2 compared to patients with high expression of either receptor alone, measured by recurrence-free survival (RFS) or by distant metastasis-free survival (DMFS) (Fig. 1f, g); as well as by the overall survival (OS) in patients with lymph node metastasis (Supplementary Fig. 1a), or in patients with endocrine therapy after surgery (Supplementary Fig. 1b).
