Across TCGA pan-cancer cohorts, DDR1 mass-spec protein is linked to patient survival in 7 of 34 cancer types, making it a survival-associated DDR1 data layer compared with 20 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher DDR1 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated DDR1 expression acts as an unfavorable survival marker, although some lineages such as LSCC and COAD show a favorable association.
LSCC, PDAC, and COAD are the cancer types where DDR1 mass-spec protein most reproducibly stratifies survival.
mass-spec protein survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
