Across TCGA pan-cancer cohorts, IGHV5-51 mass-spec protein is linked to patient survival in 8 of 34 cancer types, making it a survival-associated IGHV5-51 data layer compared with 22 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher IGHV5-51 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated IGHV5-51 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and OV show a favorable association.
COAD, UCEC, and LUAD are the cancer types where IGHV5-51 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.
