| Outline of Final Research Achievements |
Local recurrence is a major clinical issue following surgical resection in cancer. However, the dissemination and lymph node metastasis of minimal residual disease is relatively difficult to treat due to the lack of suitable therapeutic approaches. In the present study, we developed and evaluated a novel immunotherapy using a skin flap transfer treated with sensitized dendritic cells (DCs), termed the“immuno-flap” in a rat tumor model. After the local round area of skin was resected, SCC-158 cells were inoculated into the muscle surface; lastly, the groin skin flap injected with mature DCs was over-laid. Two weeks after the second DC injection, systemic immunological reactions and tumor size were measured. The DC-treated group showed a significant reduction in tumor size compared with the control. These results suggest that novel immunotherapy based on the immuno-flap method has the potential for clinical application to prevent the local recurrence of head and neck cancer patients.
