We found that high expression of CD163 was detected in 43/105 (40.9%) breast cancer tissues, and high CD163 expression was found to be significantly correlated with lymph node metastasis (p = 0.012), but not with other clinicopathological parameters, such as age and TNM stage (Table 1). Here, CD163 is linked to metastatic malignant neoplasm in the lymph nodes.
