According to Table 1, the expressions of miR‐139‐5p, miR‐940 and miR‐193a‐5p were low in most HCC patients, but the correlation between these miRNAs and pathological characteristic parameters such as tumour grade, alpha‐fetoprotein (AFP) level and metastasis were not obvious, which might because of the small size of the samples. Here, AFP is linked to hepatocellular carcinoma.
