Proposal a Polyposis Staging System to Meet the Adoption of Standardized, Evidence-Based Treatment

Abstract

Polyposis staging system is a need to develop a consensus regarding categories of increasing polyposis severity because in advance to the ultimate surgical intervention （total colectomy） we already have or will have a choice of variety of interventions such as endoscopic and chemopreventive interventions. A given category of adenomatosis severity should carry with it a corresponding intervention, so as the aggressiveness of intervention increasing as stage increases. The “clinically significant” should only be considered as an improvement in stage or delay in worsening of stage. This is a preliminary polyposis staging system under preparing by the International Society of Hereditary Gastrointestinal Tumors （InSiGHT）. It is hoped that this would enable a gradual move toward adoption of standardized, evidence-based approaches to polyposis staging and treatment.
