Fig. 4. Different pathologic responses of RVT in primary and paired regional lymph nodes.
Histologic phenotypes of primary tumors and paired regional lymph nodes from three patients. Case 1 showed no RVT in the primary tumor, with inflamed immune-activated phenotype in the N1 lymph node, but non-inflamed phenotype in the N2 lymph node. Case 2 showed 5% irRVT in the primary tumor, with inflamed immune-activated phenotype in the N1 lymph node, but non-inflamed phenotype in the N2 lymph node. Case 3 showed 60% irRVT in the primary tumor, with non-inflamed phenotype both in N1 and N2 lymph nodes.
