CD274 and neoplasm: Significant differences in the gene expression between MCPyV infection positive (n=24) vs negative (n=10) (figure 3A), spontaneous regression after biopsy positive (n=4) negative (n=29) (figure 3B), cases have lymph node or distant metastasis during the follow-up positive (n=17) negative (n=17) (figure 3C), and PD-L1 expression in tumor cells high (n=10) vs low (n=18) (figure 3D) were analyzed.
