It was divided into two subtypes such as granular and non-granular or flat types. The former shows small-granular surface consisting of granules, measuring 1.2±0.3mm, that are mostly less than 3mm in diameter. So we prefer the name of granule aggregating tumor (GAT) to nodule aggregating tumor. While the latter has a strikingly unique margin, which protrudes outside like amoebase's pseudopodia, called as \"pseudopodial-like appearance\". Interestingly, histological investigations seldom reveal carcinomatous components involving the submucosa of GATs even if it is more than 20mm in size, in contrast to relatively frequent submucosal invasion in the nongranular or flat type. Microsatellite instability (MSI) was detected in only one case of our LST series. More than 80% of LSTs over-expressed β-catenin protein, accompanied by p 53 expression that correlated with atypia. Considering mutations of many oncogenes and tumor suppressor genes investigated in polypoid-type tumors, results of β-catenin and p 53 expressions seem to be consistent with \"adenoma-carcinoma sequence theory\". The apoptosis index of the lower part of granule-aggregating tumors was significantly higher than that of the lower part (4.44±1.81 vs. 1.21±1.47 in TUNEL). Acceleration of apoptosis in cells of lower part of granule aggregating tumors may inhibit the vertical growth and result in its characteristic morphogenesis.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"松本歯科大学学会"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00232590","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-1613","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷川, 博雅"}],"nameIdentifiers":[{"nameIdentifier":"0","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-05-24"}],"displaytype":"detail","filename":"matsumoto_shigaku_29-01-01.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"matsumoto_shigaku_29-01-01.pdf","url":"https://mdu.repo.nii.ac.jp/record/594/files/matsumoto_shigaku_29-01-01.pdf"},"version_id":"19dfce29-20b4-4c98-9a5b-5538edaa87e2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"laterally spreading tumour","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"colorectum","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"apoptosis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"morphogenesis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"表層拡大型腫瘍の臨床病理学的および分子生物学的特徴 : 大腸腫瘍の側方増殖型腫瘍","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"表層拡大型腫瘍の臨床病理学的および分子生物学的特徴 : 大腸腫瘍の側方増殖型腫瘍"}]},"item_type_id":"2","owner":"3","path":["117"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-24"},"publish_date":"2012-05-24","publish_status":"0","recid":"594","relation_version_is_last":true,"title":["表層拡大型腫瘍の臨床病理学的および分子生物学的特徴 : 大腸腫瘍の側方増殖型腫瘍"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:34:34.505803+00:00"}
