Across TCGA pan-cancer cohorts, CDKAL1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CDKAL1 data layer compared with 26 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher CDKAL1 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CDKAL1 expression acts as an unfavorable survival marker, although some lineages such as LSCC and OV show a favorable association.
LSCC, PDAC, and CCRCC are the cancer types where CDKAL1 mass-spec protein most reproducibly stratifies survival.
