原发性胃淋巴瘤的诊断与治疗

摘要

目的 探讨原发性胃淋巴瘤的临床特点和治疗方法.方法 回顾性分析23例经病理证实为原发性胃淋巴瘤患者的临床资料.23例均行手术治疗,其中胃大部切除16例(D1 9例,D2 7例),全胃切除3例,姑息性切除术2例,剖腹探查术2例.术后21例患者接受辅助化疗.结果 本组总体5年生存率为80%.低度恶性14例,其巾病史5年以上有10例,生存期超过5年9例;高度恶性9例,病史5年以上有7例(失访2例),生存期超过5年2例.Ⅰ期13例,病史5年以上有10例,生存期超过5年9例;Ⅱ期7例,病史5年以上有5例(失访2例),生存期超过5年2例;Ⅲ～Ⅳ期3例,5年生存0例.根治性手术19例中病史5年以上有14例(失访1例),生存期超过5年12例;非根治性手术4例(失访2例),5年生存0例.低度恶性、早期并获得根治性切除的原发性胃淋巴瘤预后较好.结论 原发性胃淋巴瘤的术前诊断和分期主要依靠胃镜和CT检查.手术和术后辅助治疗是治疗早期原发性胃淋巴瘤的重要手段,非手术疗法是治疗晚期原发性胃淋巴瘤的主要方法.%Objeetive To probe the clinical diagnosis and surgical treatment of primary gastric lymphoma (PGL). Methods Clinical data of 23 PGL patients identified by postoperative pathology were analyzed retrospectively. Sixteen patients underwent subtotal gastrectomy,3 patients underwent total gastrectomy,2 patients underwent palliative resection and 2 patients underwent exploratory laparotomy only. Postoperatively 21 patients received adjuvant treatment(chemotherapy and/or radiotherapy).The variables analyzed were type of surgery, histological type in accordance with Kiel's classification, Involvement of lymph nodes. Ann Arbor stage classification. Results The overall 5-year survival rate of these patients Was 80%,that of low grade malignancy patients was 90%,and of high grade malignancy was 40%.Thirteen patients were classified as stage Ⅰ E and seven as stageⅡE and three as stageⅢor Ⅳ,the 5-year survival rate was 90%,67%and 0,respectively.Nineteen patients underwent radical resection with 5-year survival rate of 92.3%.No patients undergoing palliative resection have survived more than 5 years. The prognosis of PGL with low grade malignancy and that of early stages(IE and Ⅱ E)and those undergoing radical excision was better than those with high grade malignancy, that of advanced stage(Ⅲand Ⅳ),and that undergoing palliative resection. Conclusions Preoperative diagnosis relies mainly on gastroscopy with biopsy and CT scan. For patients with early stage disease,radical resection combined with adjuvant therapy is the key factor in improving the prognosis. Chemotherapy or/and radiotherapy is useful management for patients with advanced stage disease.
