Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically - differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II , III , N . Statistically significant differences were also found for the 5 - year survival rate (83.3 % in AGC, 41.2 % in SGC), the incidence of early cancer (90.1 % in AGC, 83.7 % in SGC) , and for advanced cancer (38.7 % in AGC, 22.7 % in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0 % vs. 13.0 %), coupled with the low 5 - year survival rate of advanced SGC (22.7 %), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "76653", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sato, Toshiteru"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟医学会"}]}, "item_7_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00290440", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "佐藤, 敏輝"}], "nameIdentifiers": [{"nameIdentifier": "76652", "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": "2019-08-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110007146512.pdf", "filesize": [{"value": "673.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 673400.0, "url": {"label": "110007146512.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/11258/files/110007146512.pdf"}, "version_id": "e20e8202-f71f-43a8-87b5-3416015cfa20"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "gastric cancer", "subitem_subject_scheme": "Other"}, {"subitem_subject": "asymptomatic", "subitem_subject_scheme": "Other"}, {"subitem_subject": "symptomatic", "subitem_subject_scheme": "Other"}, {"subitem_subject": "prognosis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "clinicopathological study", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "無症状胃がんと有症状胃がんの臨床病理学的検討", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "無症状胃がんと有症状胃がんの臨床病理学的検討"}, {"subitem_title": "無症状胃がんと有症状胃がんの臨床病理学的検討", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "992"], "permalink_uri": "http://hdl.handle.net/10191/19645", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-09-28"}, "publish_date": "2012-09-28", "publish_status": "0", "recid": "11258", "relation": {}, "relation_version_is_last": true, "title": ["無症状胃がんと有症状胃がんの臨床病理学的検討"], "weko_shared_id": null}
