We further analyzed related information for BLCA samples, such as OS (alive or dead), DFI (disease-free or recurrence), survival time (OS/DFI > 5 years or ≤ 5 years), age (age > 60 or ≤ 60), sex (female or male), T, N, M, stage, and the presence of TP53, KRAS, BRAF, and other common cancer-driving genetic mutations. The gene discussed is KRAS; the disease is bladder transitional cell carcinoma.
