Expression levels of LI‑cadherin and miR‑378e in the serum of patients with colorectal cancer, and the diagnostic value and prognostic significance in colorectal cancer were investigated. A total of 110 patients who were diagnosed with colorectal cancer in Weihai Central Hospital, from January 2012 to November 2014, were selected and enrolled in the experimental group, and 90 healthy subjects who underwent physical examination were enrolled in the control group. The expression level of miR‑378e in serum was detected by reverse transcription‑quantitative PCR and the expression of LI‑cadherin in serum was detected by ELISA. ROC curves of LI‑cadherin and miR‑378e were drawn and the sensitivity and specificity of the diagnosis were estimated. The association of the expression levels of LI‑cadherin and miR‑378e with the survival of the patients was analyzed. LI‑cadherin and miR‑378e expression levels were significantly higher in the control group than those in the experimental group (P<0.001). LI‑cadherin was significantly associated with the pathogenic site, the lymphatic metastasis, depth of infiltration, degree of differentiation and clinical stage (P<0.05). The sensitivity and specificity of the LI‑cadherin combined with miR‑378e detection were respectively 86 and 94%; the sensitivity of miR‑378e detection was the highest, as well as the specificity of the combined detection. At the end of the follow‑up period, the survival rates of the patients in the LI‑cadherin high‑expression group and miR‑378e high‑expression group were significantly higher than those in the low‑expression groups (P<0.05). There was a significant positive correlation between the LI‑cadherin and miR‑378e expression levels in both the experimental and control group (r=0.5845 and 0.6356, respectively; P<0.05). In conclusion, LI‑cadherin and miR‑378e are expressed at low levels in colorectal cancer, suggesting that they have a good diagnostic value for colorectal cancer and can be used as biomarkers for colorectal cancer prognosis.
