Across TCGA pan-cancer cohorts, A1BG mass-spec protein is linked to patient survival in 8 of 34 cancer types, making it a survival-associated A1BG data layer compared with 23 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher A1BG mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated A1BG expression acts as an unfavorable survival marker, although some lineages such as CCRCC and OV show a favorable association.
LUAD, COAD, and UCEC are the cancer types where A1BG 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.
