Abdominal pain was the common presenting symptom. The primary sites of the tumors were: 67 in the stomach, 24 in the small intestine, 7 in the ileocecal region, 3 in the large intestine, and 1 in the esophagus. The disease more frequently affected males than females and showed peak incidence in the 5th decade of life. Gastric lymphomas usually presented with a single lesion, but multiple lesions were frequent in the small intestine. The body and\/or antrum of the stomach were the commonest sites of the lymphomas. Gastric lymphomas were diagnosed at an earlier stage than intestinal lymphomas. There was 1 case with Hodgkin\u2019s disease. The remaining 101 patients with non-Hodgkin\u2019s lymphomas were classified according to the Rappaport and the Kiel classifications. The proportion of nodular lymphomas in the present series was 7%. The frequencies of diffuse histiocytic type ard germinal center cell tumors were 62 and 74%, respectively. Cox\u2019s multivariate analysis for prognostic factors revealed that the stage of the tumor, sex, and age were prognostically significant.<\/jats:p>","DOI":"10.1159\/000226009","type":"journal-article","created":{"date-parts":[[2009,6,18]],"date-time":"2009-06-18T03:35:18Z","timestamp":1245296118000},"page":"97-103","source":"Crossref","is-referenced-by-count":49,"title":["Primary Gastrointestinal Lymphoma"],"prefix":"10.1159","author":[{"given":"K.","family":"Aozasa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Tsujimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Nakagawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Hanai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Kurata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Nosaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,6,17]]},"container-title":["Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/226009","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000226009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T23:25:26Z","timestamp":1777677926000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000226009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,6,17]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000226009","archive":["Portico"],"relation":{},"ISSN":["0030-2414","1423-0232"],"issn-type":[{"value":"0030-2414","type":"print"},{"value":"1423-0232","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,6,17]]}}}
