Through univariate Cox and log-rank test analyses, we discerned that FCN1 exhibited prognostic significance across a spectrum of cancers, excluding BRCA, KICH, KIRP, Pheochromocytoma and Paraganglioma (PCPG), Rectum adenocarcinoma (READ), Thyroid carcinoma (THCA), and UCEC (Supplementary Figure S10A). The gene discussed is FCN1; the disease is cancer.
