Across TCGA pan-cancer cohorts, IGLV3-9 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated IGLV3-9 data layer compared with 22 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher IGLV3-9 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated IGLV3-9 expression acts as an unfavorable survival marker, although some lineages such as HNSC and CCRCC show a favorable association.
UCEC, HNSC, and CCRCC are the cancer types where IGLV3-9 mass-spec protein most reproducibly stratifies survival.
