| [ Summary ] | The term "LST" was proposed by Kudo as a superficially spreading colorectal tumor larger than 10 mm in size and has been used worldwide. In July 2013 the term “LST” was described in the Japanese Classification of Colorectal Carcinoma, 8th Edition. The definition of "LST" is an appellation for superficially spreading tumors and not a macroscopic classification. LSTs may play an important role in development of colorectal carcinoma. Estimations of both LST subclassification and pit pattern findings are essential in selecting suitable therapeutic methods. | |
