ABSTRACT
BACKGROUND:
The effect of the number of lymph node dissections (LNDs) during radical resection for colorectal cancer (CRC) on overall survival (OS) remains controversial.AIM:
To investigate the association between the number of LNDs and OS in patients with tumor node metastasis (TNM) stage I-II CRC undergoing radical resection.METHODS:
Patients who underwent radical resection for CRC at a single-center hospital between January 2011 and December 2021 were retrospectively analyzed. Cox regression analyses were performed to identify the independent predictors of OS at different T stages.RESULTS:
A total of 2850 patients who underwent laparoscopic radical resection for CRC were enrolled. At stage T1, age [P < 0.01, hazard ratio (HR) = 1.075, 95% confidence interval (CI) 1.019-1.134] and tumour size (P = 0.021, HR = 3.635, 95%CI 1.210-10.917) were independent risk factors for OS. At stage T2, age (P < 0.01, HR = 1.064, 95%CI 1.032-1.098) and overall complications (P = 0.012, HR = 2.297, 95%CI 1.200-4.397) were independent risk factors for OS. At stage T3, only age (P < 0.01, HR = 1.047, 95%CI 1.027-1.066) was an independent risk factor for OS. At stage T4, age (P < 0.01, HR = 1.057, 95%CI 1.039-1.075) and body mass index (P = 0. 034, HR = 0.941, 95%CI 0.890-0.995) were independent risk factors for OS. However, there was no association between LNDs and OS in stages I and II.CONCLUSION:
The number of LDNs did not affect the survival of patients with TNM stages I and II CRC. Therefore, insufficient LNDs should not be a cause for alarm during the surgery.
