Regarding the association between FOXD1 expression and prognosis, increased FOXD1 expression was correlated with worse OS in adrenocortical carcinoma (ACC), colon adenocarcinoma (COAD), mesothelioma (MESO), bladder urothelial carcinoma (BLCA), SARC, kidney renal papillary cell carcinoma (KIRP), brain lower grade glioma (LGG), pancreatic adenocarcinoma (PAAD), uveal melanoma (UVM), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), and with worse DFS in HNSC, KIRP, LGG, MESO, PAAD, UVM and KIRC. The gene discussed is FOXD1; the disease is bladder transitional cell carcinoma.
