Figure 7.

Macrophage cell count (cells/mm²) in tumor free and metastatic lymph nodes depending on the L-status of the primary tumor. The figure shows the median macrophage cell count (cells/mm² specimen area) in the lymph node sinus (LN sinus) depending on the lymph vessel infiltration status of the primary tumor (L0 vs. L1). Both groups of tumor draining lymph nodes have been examined (lymph nodes free of metastasis and metastatic lymph nodes). P-values generated by the ANOVA-test are indicated. a) CD68 cell count: A significantly increased count can be observed in the L1 cases. b) CD11c cell count: A significantly decreased count can be observed in the L1 cases. c) CD163 cell count: A significantly increased count can be observed in the L1 cases. d) MRC1 cell count: A significantly increased count can be observed in the L1 cases.
