Endoscopic diagnosis and treatment of colon cancer: current evidence and future directions
Colorectal cancer remains a major cause of cancer morbidity and mortality, while screening and advances in endoscopic imaging have increased detection of lesions that may be amenable to organ-preserving treatment. Accurate assessment of morphology, optical pattern, and invasion depth is central to selecting among endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), endoscopic full-thickness resection (EFTR), and surgery. This structured narrative review synthesizes contemporary evidence and m …
