| 内容記述 | Purpose: Our previous study showed carbon-ion beam irradiation for murine tumors provoked upregulation of multiple membranous molecules, which could be strongly immunogenic. To clarify the anti-metastatic effect of combined therapy of carbon-ion irradiation and immunotherapy for local tumors using an in vivo murine model. \nMethods and Materials: Local tumors inoculated with mouse squamous cell carcinoma (NR-S1) cells in synergic C3H/HeMsNrs mice were irradiated with a single dose of 6 Gy of carbon-ions (290 MeV/nucleon, 6cm spread-out Bragg peak). After one-and-a-half day from the irradiation, a-GalCer pulsed DCs were locally injected into the primary tumor. The anti-tumor effects and the anti-metastatic effects of these combined modalities were investigated. \nResults: Measured by tumor-growth delay assay, DCs injection did not indicate any enhanced effects of combination therapy. Instead, the combination of carbon-ion irradiation and DCs injection decreased the numbers and each size of lung metastases significantly. \nConclusion: Combined approach with immunotherapy significantly decreased pulmonary metastases in comparison to carbon-ion therapy alone. |
