Across TCGA pan-cancer cohorts, MIR521-1 RNA is linked to patient survival in 6 of 34 cancer types, making it the most broadly survival-associated MIR521-1 data layer compared with 2 for mutation status.
The strongest signal is observed in esophageal carcinoma (ESCA), where higher MIR521-1 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated MIR521-1 expression acts as an unfavorable survival marker, although some lineages such as STAD show a favorable association.
ESCA, STAD, and THYM are the cancer types where MIR521-1 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.
