Across TCGA pan-cancer cohorts, LCK mass-spec protein is linked to patient survival in 7 of 34 cancer types, making it a survival-associated LCK data layer compared with 24 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher LCK mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated LCK expression acts as an unfavorable survival marker, although some lineages such as CCRCC and PDAC show a favorable association.
UCEC, LUAD, and CCRCC are the cancer types where LCK 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.
