| Research Abstract |
We found that the IL-12/DC combined immunotherapy exerted effective antitumor effects on the immunosuppressed host, resulting in significant suppression of growth of the subcutaneous established tumor and complete suppression of lung and liver metastasis, without rejection of a fully allogenic skin graft. These antitumor effects were dependent on both T cells and NK cells. Noteworthily, the combined intratumoral immunotherapy and tumor resection, that is to say" neoadjuvant immunotherapy", resulted in curative treatment of immunosuppressed mice for HCC, even when the mice were challenged with intravenous injection of HCC at the time of tumor resection.
