The impact of lymph node ratio (LNR) on survival in colorectal cancer: a retrospective cohort study

Key Points

• The central aim is to explore how the lymph node ratio influences survival rates in colorectal cancer patients.
• Retrospective analysis of 211 patients with colorectal cancer who underwent curative surgical resection
• Exclusion of patients with metastatic disease and those receiving palliative surgery
• Calculation of lymph node ratio as the number of metastatic lymph nodes divided by total lymph nodes examined
• Stratification of patients into four groups based on LNR values
• Higher lymph node ratios were associated with lower survival rates
• LNR stratification provided significant prognostic information for patient outcomes
• Survival rates differed notably among the groups defined by lymph node ratio
