    摘要: Background: We have recently demonstrated that early-stage gastric diffuse large B-cell lymphomas (DLBCLs) with MALToma, as well as their MALToma counterparts, may respond to H pylori eradication therapy (HPET). The present study was conducted to evaluate the effect of HPET in stage IE gastric DLBCLs without MALToma. Methods: Seven patients (4 men and 3 women; age range, 35 to 83 years) with H pylori infection and stage IE gastric DLBCL without MALToma received HPET as first-line treatment from June 2002 through May 2006. Additional immunohistochemical reaction with anticytokeratin was performed to exclude lymphoepithelial lesions (minimal MALToma components) in DLBCL. All patients received intensive endoscopic follow-up examinations with biopsy to evaluate tumor response. Patients with significant improvement of gross lesions that accompanied regression of tumor cells were followed up without additional treatment. Patients without significant improvement were immediately referred to systemic chemotherapy. Tumors that resolved to Wotherspoon grade 2 or less after successful HPET were considered as complete histologic remission. Results: Successful HPET was achieved in all patients. There were 5 patients with complete histologic remission. The complete remission rate was 71.4% (95% confidence interval, 45.1% to 97.7%). The median duration between HPET and complete histologic remission was 2.6 months (range, 1.1 to 5.7 months). At a median follow-up of 24.2 months (range, 5.7 to 56.8 months), all patients with complete histologic remission after HPET were alive and free of lymphoma. Conclusions: A substantial portion of early-stage gastric DLBCLs without MALToma remain H pylori-dependent and can potentially be cured by HPET.
