Across TCGA pan-cancer cohorts, MIR181B1 RNA is linked to patient survival in 16 of 34 cancer types, making it the most broadly survival-associated MIR181B1 data layer compared with 2 for mutation status.
The strongest signal is observed in rectum adenocarcinoma (READ), where higher MIR181B1 RNA is associated with worse disease-free survival. In most high-consensus cancer types, elevated MIR181B1 expression acts as an unfavorable survival marker, although some lineages such as LAML and ESCA show a favorable association.
READ, LAML, and ACC are the cancer types where MIR181B1 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.
