Across TCGA pan-cancer cohorts, SNORD115-20 RNA is linked to patient survival in 10 of 34 cancer types, making it the most broadly survival-associated SNORD115-20 data layer.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher SNORD115-20 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-20 expression acts as an unfavorable survival marker, although some lineages such as PAAD and LGG show a favorable association.
LUAD, UCEC, and COAD are the cancer types where SNORD115-20 RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
