異時性ポリープ
WordNet
- a small vascular growth on the surface of a mucous membrane (同)polypus
- one of two forms that coelenterates take (e.g. a hydra or coral): usually sedentary with a hollow cylindrical body usually with a ring of tentacles around the mouth; "in some species of coelenterate, polyps are a phase in the life cycle that alternates with a medusoid phase"

- Metachronous serrated neoplasia is uncommon after right colectomy in patients with methylator colon cancers with a high degree of microsatellite instability.

Weiss, M.D., Center for Hereditary Colorectal Neoplasia, Cleveland Clinic, Cleveland, Ohio 3Department of Cancer Biology, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio.AbstractBACKGROUND: Right-sided serrated polyps are precursors to sporadic microsatellite unstable colon cancers via the methylator pathway and have a high rate of synchronous and metachronous lesions. Serrated polyps also occur in Lynch syndrome, where right-sided microsatellite unstable cancers arise from germline mutations in mismatch repair genes.

- Early stage colon cancer.
- Freeman HJ.Author information Hugh James Freeman, Department of Medicine, University of British Columbia, Vancouver V6T 1W5, Canada.AbstractEvidence has now accumulated that colonoscopy and removal of polyps, especially during screening and surveillance programs, is effective in overall risk reduction for colon cancer. After resection of malignant pedunculated colon polyps or early stage colon cancers, long-term repeated surveillance programs can also lead to detection and removal of asymptomatic high risk advanced adenomas and new early stage metachronous cancers. Early stage colon cancer can be defined as disease that appears to have been completely resected with no subsequent evidence of involvement of adjacent organs, lymph nodes or distant sites. This differs from the clinical setting of an apparent "curative" resection later pathologically upstaged following detection of malignant cells extending into adjacent organs, peritoneum, lymph nodes or other distant sites, including liver. This highly selected early stage colon cancer group remains at high risk for subsequent colon polyps and metachronous colon cancer. Precise staging is important, not only for assessing the need for adjuvant chemotherapy, but also for patient selection for continued surveillance. With advanced stages of colon cancer and a more guarded outlook, repeated surveillance should be limited. In future, novel imaging technologies (e.g., confocal endomicroscopy), coupled with increased pathological recognition of high risk markers for lymph node involvement (e.g., "tumor budding") should lead to improved staging and clinical care.

- Metachronous, colitis-associated rectal cancer that developed after sporadic adenocarcinoma in an adenoma in a patient with longstanding Crohn's disease: a case report.
- Takeyama H, Mizushima T, Nakajima K, Uemura M, Haraguchi N, Nishimura J, Hata T, Takemasa I, Yamamoto H, Doki Y, Mori M.Author information Department of Surgery, Gastroenterological Surgery, Graduate School of Medicine, Osaka University, 2-2 Yamada-Oka, Suita, Osaka 565-0871, Japan. tmizushima@gesurg.med.osaka-u.ac.jp.AbstractBACKGROUND: Colorectal cancer associated with Crohn's disease (CD) is increasing in proportion to the number of patients with CD in Japan. There are two subtypes of colorectal cancer with CD: sporadic cancer and colitis-associated cancer. Early diagnosis of colitis-associated cancer is sometimes difficult; when colorectal cancer is found in patients with CD, both colitis-associated cancer and sporadic cancer should be kept in mind. Here, we describe a case of metachronous, colitis-associated rectal cancer that developed after the complete resection of an adenoma that became a sporadic adenocarcinoma in a patient with longstanding CD. To the best of our knowledge, this is the first report of colitis-associated cancer in a patient with CD after removal of a sporadic cancer.
