Across TCGA pan-cancer cohorts, CDK11B mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CDK11B data layer compared with 25 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CDK11B mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CDK11B expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LSCC show a favorable association.
CCRCC, LSCC, and PDAC are the cancer types where CDK11B mass-spec protein most reproducibly stratifies survival.
