Abstract:

Objective

To investigate the expression of cellular Mesenchymal-Epithelial Transition Factor (cMET) in colorectal cancer, its relationship with clinicopathological features and molecular characteristics, and its prognostic value, in order to inform clinical decision-making.

Methods

In this retrospective study, 314 colorectal cancer patients who underwent surgery at the National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between April 2017 and December 2023 were included. cMET expression was assessed by immunohistochemistry, and genetic alterations in MET and other common genes (BRAF, KRAS, NRAS, TP53, PIK3CA) were analyzed via next-generation sequencing. Clinical data were collected from electronic medical records, and recurrence and survival outcomes were evaluated using SPSS.

Results

Among the 314 patients, 248 had low cMET expression and 66 had high expression. Most patients(78.34%, 246/314) had stage Ⅲ~Ⅳ disease. The median disease-free survival was 11 months, with 292 cases (92.99%) experiencing recurrence or metastasis. cMET expression was associated only with tumor differentiation, and genetic alterations varied by tumor location. Only one case showed low-level MET amplification. Kaplan-Meier analysis indicated shorter disease-free survival in stage Ⅳ patients with high cMET expression (χ2=6.224, P=0.013). Univariate and multivariate Cox regression analyses confirmed that cMET expression (HR=2.542, P=0.015) and N stage (HR=2.668, P=0.019) were independent risk factors for worse disease-free survival in stage Ⅳ colorectal cancer.

Conclusion

cMET expression can serve as a useful prognostic indicator in stage Ⅳ colorectal cancer, with high cMET expression associated with shorter disease-free survival.
