the enhanced anti-tumor effects of the combination of vaccine plus chemotherapy were due to improved vaccine effectiveness Bosutinib rather than the direct cytotoxic effect of chemotherapy on cancer cells. The combination of cyclophosphamide and doxorubicin was recently evaluated in combination with a GM CSFsecreting HER2/neu indicating whole cyst cell vaccine in patients with metastatic breast cancer. Doxorubicin Anthracyclines such as for instance doxorubicin are DNA intercalating agents used to deal with a wide array of malignancies, including carcinomas of the chest, ovary, bladder, and lung. Cancer cells subjected to cytotoxic concentrations of doxorubicin bear rapid translocation of ERp57 and calreticulin for the cell surface, causing caspase dependent immunogenic cell death, a result not seen with other DNA damaging agents. Noncytotoxic levels of doxorubicin increase IL 12 dependent antigen presentation by DCs, an impact connected with modulation of APM elements, resulting in increased effector T cell function. Gemcitabine, Inguinal canal Methotrexate, and 5 FU Antimetabolites are indicated for the treatment of a few malignancies, including carcinomas of the pancreas and colon, and HNSCC. Numerous immunomodulatory properties of these agents have been revealed. For example, gemcitabine can upregulate MHC I on tumor cells, resulting in increased sensitivity to CTL mediated lysis. Similarly, treatment of human colon carcinoma cell lines with 5 FU can increase their sensitivity to the cytotoxic effects of CD8 T cells by inducing expression of ICAM 1 and Fas. Direct effects of anti-neoplastic agents such as methotrexate on T cell cytotoxicity are also reported 69. DC function can be enhanced by antimetabolites by direct and indirect mechanisms. In one survey, immediate exposure of DCs to methotrexate led to improved antigen presentation to T cells. Excitement of DC function has been associated with Anacetrapib upregulation of APM elements and IL 12, and augmented DC function has been seen after experience of cyst cells treated with gemcitabine. It has been shown that gemcitabine can selectively reduce MDSCs in tumor bearing mice without affecting other immune cell populations. Chemotherapy Plus Radiation Cisplatin plus 5 FU chemotherapy, combined with tumor irradiation, is the standard of look after HNSCC. The mix of chemotherapy and radiation is shown to significantly decrease Bcl 2 and raise the sensitivity of human HNSCC target cells to perforin mediated, MHC restricted CTL killing, compared to target cells exposed to either method alone. The studies described in this evaluation emphasize the rational basis for the clinical combination of immunotherapy and the current standard of care for HNSCC. Other Potential Combinations The immunomodulatory capabilities of several other chemotherapeutic agents are currently being investigated, for potential use within combination with therapeutic cancer vaccines.
