Abstract | BACKGROUND: METHODS: A murine orthotopic model of head and neck squamous cell carcinoma ( HNSCC) was established to investigate the efficacy and mechanism of an RFA + interleukin-2 (IL-2) combination adenoviral gene therapy among 6 groups. Tumor volume change, apoptosis, in situ macrophage recruitment, cytotoxic T lymphocyte (CTL) activity, migration of dendritic cells into the regional lymph nodes, and systemic antitumor immunity were examined. RESULTS: RFA + IL-2 therapy induced the highest levels of macrophage recruitment and dendritic cell migration resulting in enhanced CTL activity, increased tumor apoptosis, enhanced systemic antitumor immunity, and the best inhibition of tumor growth among all groups. CONCLUSION:
