Core Tip

Core Tip: This prospective study identifies elevated preoperative systemic immune-inflammation index combined with low serum lactoferrin as independent prognostic biomarkers in elderly colon cancer patients. This cost-effective and easily measurable combination reflects both systemic inflammatory burden and immune-nutritional status, enhancing traditional tumor node metastasis staging. It holds substantial potential for individualized postoperative risk stratification in routine clinical practice.
