原发肠道非霍奇金淋巴瘤32例临床分析

目的研究原发肠道非霍奇金淋巴瘤（NHL）的临床、病理特点,治疗手段和预后因素。方法回顾性分析32例原发肠道NHL患者的临床表现、病理特征和治疗结果。全部数据应用SSPS 10．0软件进行统计处理。结果32例原发肠道NHL患者的发病部位：大肠16例（50．0％）,小肠8例（25．0％）,回盲部6例（18．8％）,多发部位2例（6．2％）。临床表现：腹痛、腹胀26例（81．2％）,腹部肿块14例（43．8％）,腹泻12例（37．5％）,便血10例（31．3％）,消瘦10例（31．3％）,发热8例（25．0％）。本组B细胞型NHL21例（65．6％）,其中弥漫大B细胞型（DLBCL）15例（46．9％）;T细胞型NHL10例（31．2％）;组织细胞型1例（3．1％）。32例中,29例患者行手术和（或）化疗,19例（59．4％）获得完全缓解。Cox多因素分析显示,Ⅲ、Ⅳ期、B症状及T细胞型,是影响预后的独立不良因素（P〈0．05）。结论原发肠道NHLI临床表现不特异,弥漫大B细胞型淋巴瘤多发;根治性手术联合化疗为最佳治疗手段;预后与分期、B症状和T细胞型有关。

Clinical analysis of 32 primary intestinal non-Hodgkin's lymphoma

OBJECTIVE: To investigate the clinical and pathological features, optimal treatment and prognostic factors in primary intestinal non-Hodgkin's lymphoma. METHODS: The clinical presentations, pathological features and therapeutic results of 32 primary intestinal non-Hodgkin's lymphoma were retrospectively analyzed. Statistical analyses were performed with SSPS 10.0 software. RESULTS: The most frequently site of the lesions in the 32 patients was the large intestine (n = 16, 50.0%), followed by small intestine (n = 8, 25.0%), ileocaecal region (n = 6, 18.8%) and multiple intestinal sites (n = 2, 6.2%). Clinical presentations were as follows: abdominal pain and/or distention (n = 26, 81.2%); abdominal mass (n = 14, 43.8%); diarrhea (n = 12, 37.5%); melena (n = 10, 31.3%); weight loss (n = 10, 31.3%) and fever (n = 8, 25.0%). Twenty-one patients (65.6%) were diagnosed as B-cell lymphoma, 15 (46.9%) were diffuse large B-cell lymphoma. Ten patients (31.2%) were diagnosed as T-cell lymphoma and one (3.1%) as histiocytic lymphoma. Twenty-nine patients were treated initially by surgery with or without chemotherapy, 19 of them (59.4%) achieved complete response. Based on Cox multivariate analysis, stage III - IV, B symptoms and T cell phenotype of the disease were the independent adverse prognostic factors (P < 0.05). CONCLUSION: The clinical presentation of primary intestinal non-Hodgkin's lymphoma are not specific clinically. Most of the histological types are diffuse large B-cell type lymphoma. Complete resection combined with chemotherapy may be the best effective approach for treatment of this disease. The prognosis of this disease are correlated with the stage, B symptoms and T cell phenotype.
