Patients with CD have been demonstrated to be at a higher risk of developing small bowel and colorectal cancers than healthy individuals. Although CD-associated anal cancer is relatively rare, patients with CD accompanied by anal or perianal lesions are at increased risk of anal cancer. Additionally, compared to ulcerative colitis, which is also an inflammatory disease, CD-related anal cancer is often detected at an advanced stage owing to the complexity of CD and is associated with a poor prognosis with frequent local recurrences. Therefore, the detection of early-stage cancer is crucial for improving the prognosis. However, the surveillance methods recommended for CD-related malignancies in the United States and Europe are similar to those for ulcerative colitis. They are not appropriate for detecting CD-related malignancies in the recto-anal region. Therefore, there is an urgent need for surveillance programs aimed at the early detection of malignant anorectal lesions in patients with CD.<\/jats:p>","DOI":"10.3748\/wjg.v30.i45.4844","type":"journal-article","created":{"date-parts":[[2024,11,13]],"date-time":"2024-11-13T07:49:56Z","timestamp":1731484196000},"page":"4844-4849","source":"Crossref","is-referenced-by-count":1,"title":["Establishment of a surveillance program for anal cancer in Crohn's disease"],"prefix":"10.3748","volume":"30","author":[{"given":"Hajime","family":"Kayano","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken-Ichi","family":"Okada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seiichiro","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuo","family":"Koyanagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2060","published-online":{"date-parts":[[2024,12,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1093\/ibd\/izy374"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v28.i23.2597"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v27.i25.3693"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v26.i42.6572"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-1253(20)30005-4"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-006-0848-z"},{"key":"B7","unstructured":"Higashi D, Katsuno H, Kimura H, Takahashi K, Ikeuchi H, Kono T, Nezu R, Hatakeyama K, Kameyama H, Sasaki I, Fukushima K, Watanabe K, Kusunoki M, Araki T, Maeda K, Kameoka S, Itabashi M, Nakao S, Maeda K, Ohge H, Watadani Y, Watanabe T, Sunami E, Hotokezaka M, Sugita A, Funayama Y, Futami K.
