Another study showed that exosome-lncRNAs ANRIL and PCAT-1 in urine could serve as potential diagnostic biomarkers for bladder cancer, with AUCs of 0.7229 (sensitivity of 46.67% and specificity of 87.5%) and 0.7292 (sensitivity of 43.33% and specificity of 87.5%), respectively [42]. Here, CDKN2B-AS1 is linked to urinary bladder cancer.
