Across TCGA pan-cancer cohorts, NPFF RNA is linked to patient survival in 1 of 34 cancer types, making it a survival-associated NPFF data layer compared with 3 for mutation status.
The strongest signal is observed in small cell lung cancer (SCLC), where higher NPFF RNA is associated with better disease-free survival. In most high-consensus cancer types, elevated NPFF expression acts as an unfavorable survival marker, although some lineages such as SCLC show a favorable association.
SCLC are the cancer types where NPFF RNA most reproducibly stratifies survival.
