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