Across TCGA pan-cancer cohorts, CDR2L mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CDR2L data layer compared with 27 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher CDR2L mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated CDR2L expression acts as an unfavorable survival marker, although some lineages such as PDAC and HNSC show a favorable association.
PDAC, GBM, and HNSC are the cancer types where CDR2L mass-spec protein most reproducibly stratifies survival.
