Across TCGA pan-cancer cohorts, CCND1 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated CCND1 data layer compared with 22 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CCND1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated CCND1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and PDAC show a favorable association.
CCRCC, LSCC, and PDAC are the cancer types where CCND1 mass-spec protein most reproducibly stratifies survival.
