原发性胃肠道恶性淋巴瘤(PGIL)是一种常见的结外恶性淋巴瘤,它的临床分期、病理分类及治疗方法仍无统一标准,误诊率高。我院1974/1997收治PGIL68例,分析如下。 1 材料和方法 1974/1997我院收治且病理证实为PGIL 68例,1998-10对59例进行了随访。采用1961年Dawson提出的PGIL 5条标准,根据1970年AnnArbor会议分期标准改良如下:病变仅累及胃肠道为Ⅰ_E期;累及胃肠道和区域淋巴结为Ⅱ_E期;累及胃肠道伴相邻组织或器官浸润、或伴膈肌对侧淋巴结受累为Ⅲ_E期;累及胃肠道并弥漫性侵犯全身性组织与器官(如肝、肺、骨等)为Ⅳ_E期。68例病理切片按1985年成都全国淋巴瘤会议标
Primary malignant lymphoma of the gastrointestinal tract (PGIL) is a common extranodal malignant lymphoma. Its clinical staging, pathological classification and treatment methods still have no uniform standard and the rate of misdiagnosis is high. Our hospital 1974/1997 admitted to PGIL68 cases, analysis is as follows. 1 Materials and Methods 1974/1997 admitted to our hospital and the pathology confirmed PGIL 68 cases, 1998-10 to 59 cases were followed up. According to the 1970 Ann Arbor meeting staging criteria, the PGIL 5 criteria proposed by Dawson in 1961 were modified as follows: Lesions involving only the gastrointestinal tract in stage I_E; Involving gastrointestinal and regional lymph nodes in stage II_E; Involving adjacent tissues in the gastrointestinal tract Or organ infiltration, or with the contralateral lymph node involvement of the diaphragm Ⅲ_E period; involved in the gastrointestinal tract and diffuse violations of systemic tissues and organs (such as liver, lung, bone, etc.) for the Ⅳ_E period. 68 cases of pathology in 1985 by the Chengdu national lymphoma conference standard
