原发性胃肠道恶性淋巴瘤33例临床分析

目的探讨原发性胃肠道恶性淋巴瘤的早期诊断及治疗。方法回顾分析1997—2005年33例原发性胃肠道恶性淋巴瘤（PGIML）患者的临床资料。结果内镜及活检确诊率为44．4％。免疫分型以B细胞为主（90．9％）。全组患者有30例经手术治疗，2例仅行Hp根除术，1例确诊后放弃治疗。术后：单纯手术者21例，2年及以上生存者19例（90．5％）；手术加化疗者9例，2年及以上生存者6例（66．7％）。在11例胃黏膜相关淋巴组织（MALT）淋巴瘤中有2例胃MALT淋巴瘤行抗Hp治疗，肿瘤消退或缩小；9例行手术切除，术后未复发。结论PGIML早期诊断较困难，可采取多种诊断手段综合诊断，手术治疗作用尚未肯定，还需进一步随访观察。

Clinical analysis of 33 cases of primary gastrointestinal malignant lymphoma

Objective To investigate the early diagnosis and treatment of primary gastrointestinal malignant lymphoma( PGIML). Methods The clinical materials of 33 cases with PGIML from 1997 to 2005 were retrospectively studied. Results The diagnosis rate of gastroenteroscopy was 44. 4% . The most common immune phenotype was B-cell lineage (90. 9% ). Of the 33 PGIML patients, 30 were treated with operation, 2 with H. poli elimination and 1 gave up treatment. Among the operation cases and operation plus chemotherapy cases 19/21 cases (90. 5% )and 6/9 cases (66. 7% ) survived more than 2 years respectively, the other 6 cases died. Conclusion It is hard to diagnose PGIML in early stage. The effectiveness of surgery on treating PGIML should be further confirmed by profound prospective randomized trials.
