The antibodies against human T-lymphocyte were anti-CD3, CD4, CD8, CD4×Leu8, CD4×4B4 and CD8×CD11.
The results were as follows.
1) Using single color analysis, the proportion of CD3+ and CD4+ cells in the metastatic lymph node was decreased and that of CD8+ cells was not changed compared with the non-metastatic lymph node. Therefore, the ratio of CD4 to CD8 was reduced.
Using two color analysis, proportion of CD4+ Leu8- cells and CD4+ 4B4- cells was reduced. On the contrary, that of CD8+ CD11+ cells was increased in the metastatic lymph node compared with the non-metastatic lymph node.
2) The proportion of CD3+, CD4+ and CD4+ 4B4- cells was decreased in the non-metastatic lymph node of patients with lymph node metastasis compared with that of patients without lymph node metastasis.
3) The proportion of T-lymph nocyte subsets was not changed in the metastatic lymph node, whether the volume including cancer cell is much or not.
These results suggest that the metastatic lymph node was less defensive against lymph node metastasis in the gastric cancer.
