متن کاملClaudin expression in rectal well-differentiated endocrine neoplasms (carcinoid tumors).
Claudins are the structures and functional components of tight junctions and have crucial roles in the maintenance of cell polarity, cellular arrangement, adhesion and paracellular transport. Various claudins are expressed in different epithelial cells and most tissues express multiple claudin proteins. The altered expression of claudins has been reported in various human carcinomas, but their ...

submucosal dissection, and local surgical excision, including transanal excision and transanal endoscopic microsurgery (TEM). In a study by Kim et al. [6], the complete resection rate for TEM was over 97%. Although TEM is superior to other endoscopic procedures, TEM must be considered to be more invasive because of the risk associated with the use of anesthesia. Third, guidelines for follow-up ...
