Core Tip
Core Tip: The study by Sala-Miquel et al evaluated the diagnostic efficacy of follow-up strategies, including computed tomography, colonoscopy, and tumor markers, in detecting recurrences or metastases after surgery for non-metastatic colorectal cancer (CRC). At the same time, the study highlighted the importance of these tools in optimizing post-surgical care; its retrospective, single-center design limits generalizability. Future research should adopt multicenter, prospective designs and include control groups to reduce bias and improve applicability. Addressing confounders like comorbidities and socioeconomic factors, alongside sensitivity analyses, would improve statistical robustness. Integrating emerging technologies such as circulating tumor DNA and patient-centered approaches can enhance diagnostic accuracy and adherence, ultimately refining CRC surveillance outcomes.
