ABCB1

mass-spec protein & survival
Survivalmass-specKaplan–Meier · TCGA cohorts

Across TCGA pan-cancer cohorts, ABCB1 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated ABCB1 data layer compared with 24 for mass-spec protein and 9 for mutation status.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher ABCB1 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated ABCB1 expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.

PDAC, LSCC, and CCRCC are the cancer types where ABCB1 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.
