Genetics of Aberrant Immune Responses During Tumor Progression Among Iranian Population

The immune system has a critical tumor suppressor function via the detection and elimination of the tumor cells. Tumor cells' immune escaping is commonly observed during neoplastic transformations. Immune response suppression or aberrations facilitate immune escape that promotes tumor progression in distant or primary locations via epithelial-mesenchymal transition and angiogenesis, respectively. It has been reported that there is a rising trend of cancer incidence among the Iranian population. Since aberrant immune responses are involved in tumorigenesis; immunotherapeutic methods can be efficient for tumor cell elimination. In the present review, we discussed all of the immune-related genes that have been associated with tumor progression among the Iranian population to clarify the genetics of immune deficiency during tumor progression in this population. T regulatory and T helper related genes were the most frequently deregulated genes during tumor progression in the Iranian population. This review paves the way to suggest an immune-specific panel of genetic markers for diagnostic and immunotherapeutic purposes among Iranian cancer patients.
