Then, a comprehensive and systematic analysis of the data using various databases showed that high expression of PTPRC was significantly associated with a better prognosis, while a RiskScore calculated from PTPRC expression revealed a worse prognosis in the high-risk group, suggesting that PTPRC expression was expressed by infiltrating immune cells rather than cancer cells present in the tissue, which is associated with an immune response. This evidence concerns the gene PTPRC and cancer.
