Clinical significance of 206 station lymph node in transverse colon cancer.


ABSTRACT:

Background

Lymph node (LN) metastasis is crucial in determining the prognosis and treatment options for colon cancer patients. Our work was to study whether the lymph nodes beyond D3 station in transverse colon cancer, especially 206 LN, should be dissected.

Methods

A total of 225 patients within our department were reviewed. The primary and secondary endpoints were overall survival (OS) and disease-free survival (DFS). We employed Propensity score weighting (PSW) for weighing participants to balance observed confounders between the 206D+ group and the 206D- group.

Results

The rate of metastasis in station 206 was 9.3%. Only T stage (OR, 3.009; 95% CI, 1.018-8.892), N stage (OR, 9.818; 95% CI, 1.158-83.227), and M stage (OR, 26.126; 95% CI, 1.274-535.945) were an independent risk factor for 206 station metastasis in multivariate logistic analysis. The 206D+ group had a similarly survival than the 206D- group (3-year DFS, 89.6% v 85.9%; p = 0.389; 3-year OS, 94.6% v 85.3% p = 0.989). PSW further verified it. Metastasis of 206 station LN is not an independent prognostic factor, but a predictive factor of DFS.

Conclusion

Station 206 LN positive is a predictive factor for DFS. Only the patient with T1-3, N+ who is at a high risk of 206 station LN metastases should consider dissecting 206 station LN.
