Impact of MMR status on preoperative CT-based lymph node overstaging in right-sided colon cancer: a retrospective analysis

Key Points

• Lymph node overstaging is notably influenced by MMR status, highlighting its significance in preoperative assessments.
• Among patients with right-sided colon cancer, overstaging occurred in 45%, suggesting a critical diagnostic challenge.
• Retrospective analysis examined CT findings and MMR status in a cohort of 150 patients, providing valuable insights.
• Relevance underscores the need for careful preoperative evaluation, particularly in MMR-deficient cases, to avoid mismanagement.
