Application of immunological treatment of cancer
In treating a cancer patient with fourth stage melano-carcinoma, not melanoma, surgery and chemotherapy had proven ineffective, and after three months of treatment, tumor cells had begun to spread to other organs, so the director of oncology at the Taipei Veterans General Hospital Liu Chun-huang introduced immunological treatment of cancer by injection of anti-cancer medication once every three weeks. By the fourth injection, the patient’s survival rate was extended to one year up to the present time.
Immunological treatment of cancer stops the CTLA-4 from inhibiting T cell responses, thus strengthening T cells in fighting cancerous cells. T cell responses result from a balance between the stimulatory and inhibitory signals of Cytotoxic T lymphocyte associated molecule 4 (CTLA-4), a cell surface molecule that maintains T cell homeostasis.
