FTL expression was significantly associated with PFI in four cancer types (Figure 3A): LGG (HR 1.5, 95% CI 1.26–1.78, P = 3.8 × 10−6), KIRC (HR 1.31, 95% CI 1.06–1.62, P = 1.4 × 10−2), UCEC (HR 1.21, 95% CI 1.00–1.46, P = 4.4 × 10−2), and GBM (HR 1.26, 95% CI 1.02–1.57, P = 3.3 × 10−2). The gene discussed is FTL; the disease is cancer.
