Our findings in the TCGA cohort were contrasting, as they diverged from the results obtained from the previous two cohorts; we found that A2AR expression was related to a good prognosis, and this was observed in patients with an astrocytoma (Table 5).This is depicted in the survival curve plot of A2AR expression in TCGA patients with astrocytoma histological type, which is shown in Figure 6. The gene discussed is ADORA2A; the disease is astrocytoma (excluding glioblastoma).
