Besides, the immune score and stromal score were higher in Cluster A than in Cluster B (Figure 3(d)), and the enrichment scores of the T cell receptor (TCR) and B cell receptor (BCR) were also higher in Cluster A (Figure 3(e)), which together demonstrated that the longer OS of Cluster A might attribute to the tumor microenvironment (TME)-infiltrated immune cells, while the poor prognosis of Cluster B might be associated with the tumorigenesis of cancer hallmarks. The gene discussed is BCR; the disease is neoplasm.
