Core Tip
Core Tip: A study by Zhu SS et al reported that the systemic immune-inflammation index and serum lactoferrin levels predict survival in elderly patients with colon cancer. While promising, the study was limited by a small, single-center cohort, a short follow-up period, and an incomplete adjustment for confounders. Predictive accuracy was only moderate, yet conclusions were overstated. To ensure clinical utility, future research should validate systemic immune-inflammation index and lactoferrin in larger, multicenter studies with longer follow-up, benchmark them against established prognostic indices, and incorporate molecular markers. Such efforts are crucial to establishing reliable, externally validated prognostic tools for the individualized management of older colon cancer patients.
