The Morphologic Assessment of Rectal Neuroendocrine Tumors

Conclusions Endoscopic features such as hyperemic change, polypoid lesions, irregular contours, and surface ulcers with tumor size ≥10mm in diameter are associated with metastasis in rectal NETs. In particular, atypical endoscopic features including hyperemic change, and surface ulcer with tumor size ≥10mm in diameter may help to predict the risk of metastasis of rectal NETs.
