Sågtandande polyper en dold men vanlig orsak till kolorektal cancer : Serrated polyps is a hidden but common cause of colorectal cancer
Serrated polyps is a hidden but common cause of colorectal cancer
Author
Summary, in English
Konceptet att sågtandande polyper kan leda till kolorektal cancer är relativt nytt.
Sågtandade polyper orsakar upp till en tredjedel av all sporadisk kolorektal cancer.
Trots detta är kunskaperna om sågtandade polypers etiologi, incidens, prevalens och naturalförlopp ofullständiga.
Sågtandade polyper är svåra att identifiera och ta bort endoskopiskt.
Endoskopister och patologer måste ha kunskaper om sågtandade adenom för att effektivt kunna detektera, diagnostisera och ta bort dem som led i att minska antalet personer som drabbas av kolorektal cancer.
The concept that serrated polyps can cause colorectal cancer is relatively new and not very well-known. Serrated polyps are difficult to identify and treat endoscopically. This together with the fact that premalignant serrated polyps are mainly located in the proximal colon might help explain why colonoscopy is less effective against right-sided compared to left-sided colorectal cancers and why interval cancers usually appear in the proximal colon. In fact, serrated polyps may cause up to one third of all sporadic colorectal cancers. In spite of this, the aetiology, incidence, prevalence and natural history of serrated polyps remains elusive. Endoscopists and pathologists must have a good understanding of serrated polyps in order to effectively diagnose, treat and follow up these lesions. This review focuses on the pathophysiology, types, work-up, treatment and follow-up of serrated polyps in the colon and rectum.
