The Kaplan-Meier curves showed that increased FH expression was correlated with poor prognosis in 6 cancer types including ACC (P = 0.00069, HR = 1.01), KICH (P < 0.0001, HR = 1.02), LAML (P < 0.0001, HR = 1.02), LGG (P < 0.0001, HR = 1), LUAD (P = 0.014, HR = 1), and SKCM (P < 0.0001, HR = 1). The gene discussed is FH; the disease is adrenal cortex carcinoma.
