Despite recent advances in colorectal cancer (CRC) treatment, the prognosis of patients suffering from this malignancy still remains substandard, and metastatic recurrence following curative surgery is the leading cause of mortality. Therefore, it is imperative to identify prognostic markers to predict the clinical outcome of CRC patients. Recent evidence revealed the new role of small nucleolar RNAs (snoRNAs) in oncogenesis. Herein, we systematically evaluated dysregulation of snoRNAs in CRC and clarified their biomarker potential and biological significance in CRC.
