However, anecdotal cases of regression of high-grade lymphomas after the cure of H pylori infection had been described.

Then, patients underwent intensive endoscopic follow-up examinations (\u00b1 endoscopic ultrasonography) with biopsy to evaluate tumor response.

All 10 of these patients with early response had subsequent complete histologic remission of lymphoma. The complete remission rate was 62.5% (95% confidence interval, 35.8% to 89.1%). The response rate was not affected by the tumor grading (proportion of large blast cells within the tumor) but was adversely affected by the depth of tumor invasion. At a median follow-up of 43.5 months (range, 21.1 to 67.4 months), all 10 of these patients remained lymphoma-free. The median duration of complete response was 31.2 months (range, 14.4 to 49.1 months).<\/jats:p>\n                  <jats:p>CONCLUSION: These results suggest that high-grade transformation is not necessarily associated with the loss of H pyloridependence in early-stage MALT lymphomas of the stomach.<\/jats:p>","DOI":"10.1200\/jco.2001.19.22.4245","type":"journal-article","created":{"date-parts":[[2017,2,24]],"date-time":"2017-02-24T02:46:20Z","timestamp":1487904380000},"page":"4245-4251","source":"Crossref","is-referenced-by-count":81,"title":["Prospective Study of\n                    <i>Helicobacter pylori<\/i>\n                    Eradication Therapy in Stage I\n                    <sub>E<\/sub>\n                    High-Grade Mucosa-Associated Lymphoid Tissue Lymphoma of the Stomach"],"prefix":"10.1200","volume":"19","author":[{"given":"Li-Tzong","family":"Chen","sequence":"first","affiliation":[{"name":"From the Division of Cancer Research, National Health Research Institutes;
