原发性胃肠道恶性淋巴瘤临床分析

目的 探讨原发性胃肠道恶性淋巴瘤(PGIML)的临床及病理特点。方法 回顾性总 结分析PGIML22例资料,所有病例均经内镜活检或手术后病理组织学所证实。结果 腹痛是PCIML 最常见的症状,达68.2％(15／22);胃是最常见的发生部位,达54.5％(12／22)。黏膜表面呈肿块结节 是PGIML最常见的内镜表现,达71.4％(15／21),内镜活检诊断PGIML的阳性率为52.6％(10／19)。 22例均为非何杰金淋巴瘤,20例为黏膜相关淋巴组织(MALT)淋巴瘤,其中13例为MALT型结外边 缘区B细胞淋巴瘤。结论PGIML以腹痛为主要临床表现,胃的发生率最高,主要病理类型为MALT 型结外边缘区B细胞淋巴瘤,其预后与手术方式和术后化疗有关。

A clinical analysis with primary gastrointestinal malignant lymphoma

Objective To investigate the clinical and histopathologic features of patients with primary gastrointestinal malignant lymphoma ( PGIML). Methods The clinical and histopathologic data of 22 patients with PGIML were reviewed and analyzed retrospectively. All cases were confirmed with histological specimen obtained from endoscopic biopsies or surgery. Results Abdominal pain was the most common presenting symptom, seen in 15 of 22 patients (68.2% ). The incidence of PGIML was highest in stomach, seen in 12 of 22 patients (54. 5% ). Modularity of the mucosal surface was the most common endoscopic finding, seen in 15 of 21 patients (71. 4% ). The positive rate of endoscopic biopsy for the diagnosis of PGIML was 52. 6% (10/19 biopsy cases). All cases were non-Hodgkins lymphomas ( NHL). Twenty cases were muco-sa associated lymphoid tissue (MALT) lymphoma, and 13 of 20 cases were extra-nodal marginal zone B-cell lymphoma of MALT. Conclusions Abdominal pain is the most common symptom and the stomach was the most common location in PGIML. Extra nodal marginal zone B-cell lymphoma of MALT is the main histopathologic feature. The prognosis of PGIML is related to the surgical procedure and the post operative chemotherapy.
