To further elucidate the potential impact of ARPC2 on pan-cancer prognosis, the association between ARPC2 and clinicopathological characteristics was evaluated in 10 cancer types (ACC, HNSC, KIRC, KIRP, LGG, LIHC, MESO, PAAD, UCEC, and UVM), whose prognoses were significantly affected by the expression of ARPC2 based on the previously mentioned Kaplan–Meier analyses. This evidence concerns the gene ARPC2 and adrenal cortex carcinoma.
