Recent studies indicate that functional T-lymphocyte defects compromise anti-tumor responses in various cancers. It appears that tumors not only effectively bypassed the host immune system, but have also actively corrupted the host anti-tumor response via several distinct mechanisms. Cancer Immunotherapy has made significant strides in recent years, due to improved understanding of the underlying principles of tumor biology and immunobiology. This review attempts to identify strategic factors involved in anti-cancer immune impairment, understand the mechanisms underlying reported immunosuppression and highlight some of the most promising present day immunotherapy approaches progressing successfully in clinics.
