Five years of complete remission of gastric diffuse large B cell lymphoma after eradication of Helicobacter pylori infection

Long term follow up data are not available for cases of diffuse large B cell gastric lymphoma treated by eradicating Helicobacter pylori alone. We present the case of an 82 year old man with diffuse large B cell lymphoma localised to the stomach which responded to H pylori eradication and which has not recurred after more than five years of close follow up. Our patient was not a candidate for other modalities of treatment. This case demonstrates that the option of treating H pylori infection as the initial trial of treatment for localised diffuse large B cell lymphoma is appropriate for consideration. If medical therapy using eradication of H pylori is used, it is essential that the patient undergoes close observation and repeated surveillance endoscopies.
