Abstract

Purpose: This study aimed to explore the clinical factors associated with lymph node metastasis (LNM) and survival in T2 colon cancer.

Method: Patients with T2 colon cancer and receiving radical surgery from 2017 to 2021 in our hospital were retrospectively enrolled. Patients were divided into two groups according to the LN status (LNM, non-LNM). The demographic, radiological, pathological, and survival data were collected and analyzed. Logistic regression was used to find the factors associated with LNM, and cox regression was adopted to identify factors contributing to poor survival. All the data analysis was performed by SPSS 22.0 and R.

Results: A total of 150 patients were included in this study, among them thirty were with LNM (20%). The LNM group had significantly higher incidence of lymph-vascular invasion (LVI) and perineural invasion. Besides, positive LNs had more proportion of irregular margin (P < 0.001) and heterogeneity (P < 0.001) than the negative ones. The multivariate analysis indicated that LVI and heterogeneity of LN were independent risk factors of LNM in T2 colon cancer. The disease-free survival (DFS) was 80% and 93.3% in the LNM and non-LNM group (P = 0.02), respectively. Besides, the overall survival (OS) was 92.9% and 95% in the LNM and non-LNM group (P = 0.103), respectively. The results indicated that elevated CA199 value and LNM were independent risk factors contributing to poorer OS and DFS.

Conclusion: The current data indicated LVI and LN heterogeneity were independent risk factors of LNM in T2 colon cancer. More extended surgery should be considered when these factors were detected.
