ROR1 and breast cancer: Due to the very limited survival information from TCGA breast cancer (around 15%), we utilized the widely-used KMplotter [32] and found that higher ROR1 expression predicts shorter distal-metastasis-free survival (DMFS) in a total of 1746 breast cancer patients (Figure 1c, Affymetrix max probe for ROR1: 205805_s_at).
