OBJECTIVES: We aimed to explore the association between metformin treatment and
epithelial-mesenchymal transition (EMT) phenotype and further appraise the
prognostic values of metformin and EMT markers E-cadherin and vimentin for
colorectal cancer (CRC) in clinical practice. METHODS: We collected specimens and
evaluated clinicopathological parameters of 102 stage I to III CRC patients with
prediagnosed type 2 diabetes mellitus (DM II). Expression of E-cadherin and
vimentin in tumors was detected by immunohistochemistry (IHC), and statistical
analysis was performed using SPSS 19.0. RESULTS: In correlation tests, we found a
lower tumor cell EMT degree (more E-cadherin (P = 0.014) and less vimentin (P =
0.011) expression in patients who used metformin, and the expression of
E-cadherin and vimentin was associated with serum CA19-9 (P = 0.048, P = 0.009),
tumor invasive depth (T) (P < 0.001, P = 0.045), and lymph invasion (N) (P =
0.013, P = 0.001). In Cox multivariate regression analysis, E-cadherin was
identified as a prognostic factor for disease-free survival (DFS) (P = 0.038) and
metformin use (P = 0.015P = 0.044) and lymph invasion (P = 0.016P = 0.023) were
considered as the prognostic factors for both DFS and overall survival (OS).
CONCLUSION: Our study suggested that metformin may impede the EMT process and
improve survival for stage I-III CRC patients with DM II.
