Objective: To explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer, and to explore its risk factors and its impact on tumor staging.
Methods: Cases of rectal cancer patients underwent proctectomy surgery were collected in this study. Clinical features of patients, including gender, age, BMI, tumor size, pathological type, differentiation, nerve invasion, lymph nodes, tumor marker and pathological examinations were analyzed.
Results: A total of 485 cases were included in this study. There were 29 cases with IMA-LN metastasis, the metastasis rate was 5.98% (29/485). Positive IMA-LNs were associated with distance from anal verge, CEA, pathological type, differentiation, nerve invasion, T stage and N stage. Multivariate analysis showed that distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs.
Conclusion: Distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. No skip metastasis occurred in IMA-LNs. We should choose the appropriate surgical methods to achieve better oncological results and reduce the incidence of postoperative complications.
