Moreover, both univariate and multivariate analyses confirmed that higher numbers of CD204-positive TAMs in tumor stroma were an independent worse prognostic predictor for adenocarcinoma.
The number of podoplanin-positive cancer-associated fibroblasts and CD204-positive tumor-associated macrophages was significantly lower in Lep+ adenocarcinomas (podoplanin-positive cancer-associated fibroblasts: 0 vs 0 [mean: 1.6 vs 11.6], P < .01; CD204-positive tumor-associated macrophages: 8.7 vs 24.7, P < .01).
Each of a highly proliferative gland measured by Ki-67 labeling, cellular atypical grade, gastric phenotype defined by MUC5AC and MUC6 and CD204-positive tumor-associated macrophage (TAM) was a significant risk factor for adenocarcinoma development in gastric adenoma by univariate analysis.
