GASTRIC LYMPHOMAS: 25+ Years of Revolution/Evolution
نویسنده
چکیده
The gastrointestinal tract is the most common location of extranodal lymphomas and the stomach in particular serves as an excellent model to illustrate many of the general issues concerning extranodal lymphomas. The stomach is the most frequent site of involvement of extranodal gastrointestinal lymphomas with small intestine second in frequency. Large intestinal and rectal lymphomas are less common, but are found in patients with AIDS and occasionally as a complication of ulcerative colitis and Crohn disease. In a study of 371 patients with primary gastrointestinal lymphomas registered in a German Multicenter Study, stomach accounted for 277 of cases ((74.8%). Curiously, the incidence of primary gastric lymphomas in the United States is increasing, specifically in patients over 60 years of age; this increase appears independent of the AIDS epidemic and the now common diagnosis of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type.
