Core Tip

Core tip: Although several reviews in the literature have analyzed the different surveillance strategies for colorectal cancer, this is the most updated review that includes the current state of surveillance approaches with endoscopy and imaging, the most recently completed clinical trials and meta-analysis that failed to demonstrate survival benefit from traditional intensive surveillance strategies recommended by professional guidelines, real-world data, and recommendations for special populations.
