ABSTRACT
Colorectal cancer is one of the common malignant tumors and the overall prognosis is poor. The search for a more effective treatment for colorectal cancer has never stopped. The current interaction between the modulated immune system and the tumor microenvironment is a hot topic in the treatment of colorectal cancer. The achievements involve immune checkpoint inhibition, cytokine therapy, toll?like receptors and autologous cell therapy. It has been proved that these methods have mild effect on tumor loading reduction. However, significant breakthrough has been achieved with the use of checkpoint inhibitors targeting cytotoxic T lymphocyte associated antigen?4 (CTLA?4),programmed death?1 (PD?1) and programmed death receptor ligand 1 (PD?L1). Immunotherapy is promising in the treatment of patients with refractory tumors. The success of this current immunotherapy approach is largely limited to tumors with high mutation amplification, such as melanoma,renal cell carcinoma ( RCC) and non?small cell lung cancer. However,this discovery has led the development of checkpoint inhibitors in the treatment of colorectal cancer with highly mutated amplification of mismatch repair gene to a new era.
ABSTRACT
Malignant tumors have become one of the major diseases endangering human health.In recent years,the incidence and mortality of cancer have been increasing.The survival rate is only about 50％ for the cancer patients after common therapists,includes surgery,radiotherapy,and chemotherapy.By facing the severe challenge of choosing treatment method,the more effective cancer treatment has become the focus of clinical researches.Biotherapy is a new tumor therapy method with significant curative effect,and is a new treatment for autoimmune cancer.The application progress of biotherapeutic technologies in cancer therapy were reviewed,including nonspecific immunotherapy,cytokine therapy,adoptive cell therapy,monoclonal antibody therapy and gene therapy.
ABSTRACT
Breast cancer is the principal cause of death in malig-nancy women , usually treated with the combination of surgery , chemotherapy , radiotherapy and endocrinotherapy .With the de-velopment of cell biology , molecular biology , immunology, im-munotherapy becomes a new field of breast cancer treatment .In this review, we discuss new findings in breast cancer immuno-therapy , including recent successes with bispecific antibodies and immune checkpoint blockade .We also discuss therapeutic cancer vaccines and highlight several additional immunotherapy modalities in early stages of development .
ABSTRACT
Complementary medicine aimed at improving patients’ QOL by complementing modern medicine has recently become the focus of attention. These alternative supplements or functional foods are commonly biologically based. Contained within food itself, these specialized components serve a tertiary function regarding biological regulation and defense. Further, in vivo mechanisms are considered to be closely linked to mucosal immunity of the intestine. As the mechanism of innate immunity is further elucidated, the significant role of certain food components in relation to mucosal immunity of the intestine has become a focus of interest.<br> In this paper, I would like to describe the experimental and clinical applications of complementary medicine in cases of chronic and/or intractable inflammatory bowel disease.<br>
