Vaccine Based immunotherapy against Gastric carcinoma.

Vaccine based therapy is a part immunotherapy. Recently, it has been approved to be an effective treatment strategy against some cancers. Immune based therapy in cancer has emerged as a powerful and promising clinical approach for treatment and has shown major success in some cancer. Therefore, it has been seen to be an effective option against gastric carcinoma.

Generally vaccines activate and expand tumor-specific T cells as effector T cells. They may act by increasing already existing immunity, by inducing new immunity, or by anti tumor response alike. Tumor specific T cell can be brought upon by peptides stemmed from tumor-related antigens at the T cell sites. Effective vaccination requires these peptides to be presented by a professional antigen-presenting cell, such as a dendritic cell (DC). Immature dendritic cell with high phagocytic capacity which are gathered in peripheral tissues, are more so localized to tumor growing sites. They take up antigens which are digested into small oligopeptides.  They bound to significant major histocompatibility complex (MHC) class I/II elements for presentation to Cd8+ and to Cd4+ helper cytotoxic T Cells.

Tumor antigen-pulsed DC-based antibodies have been confirmed to activate both Cd8+ and Cd4+ T-cell reactions in patients with advanced malignancies^. Although clinical trials utilizing DC-based immunizations in patients with advanced malignancies have encouraged into positive immunologic endpoints. Both protein and peptide targets have been used to attempt to stimulate a specific immune response in gastric cancer.  The experiments based on peptides derived from the tumor associated antigen HER2/neu-derived peptide and MAGE (melanoma associated antigen) which are restricted to MHC class I have been shown to induce cytotoxic T cells against tumors. Gastric cancers typically overexpress HER-2/neu and vaccination using dendritic cells pulsed with HER-2/neu peptide which results in decreased tumor. Therefore, primary goal of a cancer vaccine also part of immunotherapy is not only to prevent disease but to generate an active immune response against an existing cancer.

Immune based therapy has greatly improved and is becoming an important factor in such fields as medical care and welfare for human being. Progress has been rapid ensuring that the future of this therapy for gastric cancer is bright.
