Across TCGA pan-cancer cohorts, HMBOX1 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated HMBOX1 data layer compared with 21 for mass-spec protein and 5 for mass-spec protein.
The strongest signal is observed in small cell lung cancer (SCLC), where higher HMBOX1 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated HMBOX1 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
SCLC, SARC, and UCEC are the cancer types where HMBOX1 Mutation most reproducibly stratifies survival.
