Correlations of Tumor-associated Macrophage Subtypes with Liver Metastases of Colorectal Cancer

Abstract

Effects of TAMs on liver metastasis of colorectal cancer do not depend on the total number of TAMs, but on the number and proportion of functional subtypes M1 and M2. M2 number and M2/ M1 ratio are more accurate predictors for liver metastasis of colorectal cancer.
