Across TCGA pan-cancer cohorts, GUCA1A mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated GUCA1A data layer compared with 24 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher GUCA1A mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated GUCA1A expression acts as an unfavorable survival marker, although some lineages such as UCEC and PDAC show a favorable association.
UCEC and PDAC are the cancer types where GUCA1A mass-spec protein most reproducibly stratifies survival.
