Figure 3From: Breast cancer biological subtypes and protein expression predict for the preferential distant metastasis sites: a nationwide cohort studyAssociation of eight breast tumor proteins with the first sites of distant metastases. The dark-shaded (lower) parts of the columns depict the proportion of cancers that gave rise to more than one first metastatic site. The total number of metastatic sites is provided in each panel. CK5, cytokeratin-5; COX2, cyclooxygenase 2; EGFR, epidermal growth factor receptor; ER, estrogen receptor; HER2, human epidermal growth factor receptor-2; PgR, progesterone receptor.Back to article page
