Across TCGA pan-cancer cohorts, ARID1B RNA is linked to patient survival in 25 of 34 cancer types, making it the most broadly survival-associated ARID1B data layer compared with 11 for mutation status and 6 for mass-spec protein.
The strongest signal is observed in small cell lung cancer (SCLC), where higher ARID1B RNA is associated with better overall survival. In most high-consensus cancer types, elevated ARID1B expression acts as an unfavorable survival marker, although some lineages such as SCLC and KIRC show a favorable association.
SCLC, OV, and KIRC are the cancer types where ARID1B 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.
