Across TCGA pan-cancer cohorts, SNORD70B RNA is linked to patient survival in 11 of 34 cancer types, making it the most broadly survival-associated SNORD70B data layer.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher SNORD70B RNA is associated with better disease-free survival. In most high-consensus cancer types, elevated SNORD70B expression acts as an unfavorable survival marker, although some lineages such as LUAD and READ show a favorable association.
LUAD, LUSC, and READ are the cancer types where SNORD70B 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.
