Across TCGA pan-cancer cohorts, SNORD115-19 RNA is linked to patient survival in 2 of 34 cancer types, making it the most broadly survival-associated SNORD115-19 data layer.

The strongest signal is observed in stomach adenocarcinoma (STAD), where higher SNORD115-19 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-19 expression acts as an unfavorable survival marker.

STAD and PRAD are the cancer types where SNORD115-19 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.
