Across TCGA pan-cancer cohorts, MIR891B RNA is linked to patient survival in 3 of 34 cancer types, making it the most broadly survival-associated MIR891B data layer compared with 1 for mutation status.

The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where higher MIR891B RNA is associated with worse disease-free survival. In most high-consensus cancer types, elevated MIR891B expression acts as an unfavorable survival marker.

KIRC, STAD, and UCEC are the cancer types where MIR891B 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.
