RESUMEN
Sixty - eight cancer patients were treated with tumor infiltrating lymphocytes transferred by local injection (local group) , in vein injecition (vein group) and in vein + local injection (vein + local group) respectively. We have analysed the anticancer efficacy and one year survival rate of patients with different transfer ways. It showed that the anticancer efficacy of the local group (85. 7%) was higher than that of vein group (48. 6%), but the one year survival rate of local group (66%) was lower than that of the vein group (80%). Comparative studies on circulating lymphocytes of cancer patients demonstrated that the increase of CD3+, CD8+, CD4+ T lymphocytes of vein group were higer than that of local group, but not different from that of vein + local group. These results suggest the possibility that in vein transfer of TILs could induce immuno -activation of cellular immunity to enhance the one year survial rate.
