原发性胃恶性淋巴瘤22例临床分析

目的 探讨原发性胃恶性淋巴瘤(PGML)的诊断和治疗。方法回顾性分析经病理确诊的22例PGML的临床资料。结果术前X线钡透误诊率89．5％，胃镜及病理活检误诊率82．5％，肿瘤切除率95．5％，根治性切除68．2％，姑息性切除27．3％，1例剖腹探查，无手术死亡，术后化疗14例。术后随访：根治性切除组5年生存率60．0％。结论PGML术前诊断困难，手术治疗应积极，全胃切除指征可适当放宽，根治性切除肿瘤和术后化疗可明显提高生存率。

Clinical Analyses on 22 Cases of Primary Gastric Malignant Lymphoma

Objective To research the diagnosis and treatment of primary gastric malignant lymphoma (PGML). Methods The clinical materials of 22 cases with PGML were analyzed retrospectively. Results The misdiagnosis rate of X - ray with barium meal was 89.5% , gastroscope and biopsy 82.5% . The resection rate of tumor was 95.5% , in which permanent resection rate is 68.2% , indulgent resection rate 27.3% . One case was with exploratory laparotomy. No patients died during the operation. Fourteen cases received postoperative chemotherapy. Follow- up showed that the five- year survival rate was 60. 0% in all cases. Conclusions The diagnosis of PGML is difficult before operation. Surgical operation should be firstly employed. The condition of whole stomach resection should be decreased. A combination of permanent resection operation and chemotherapy can increase the five- year survival rate evidently.
