By including 785 CRC patients in this meta-analysis, the findings provide evidence for the significant association between DCLK1 expression and CRC prognosis, indicating the potential clinical utility of DCLK1 in CRC, although the specific difference in DCLK1 isoforms expression (DCLK1-L and DCLK1-S) in CRC has been ignored in these studies. Here, DCLK1 is linked to colorectal carcinoma.
