Background & objectives: Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a common marginal zone lymphoma. The stomach is the relatively common origin of the MALT lymphoma, now termed as extranodal marginal zone B-cell lymphoma. Gastric MALT lymphoma has good prognosis due to clinical response to treatment and favourable overall survival. In this study, clinical characteristics and treatment of patients of early gastric MALT lymphoma were retrospectively analysed.
Methods: Seventy patients with stages I-II MALT-lymphoma treated from April 2003 to August 2015 were included. The most common symptoms were abdominal discomfort, nausea, vomiting and other digestive symptoms. Helicobacter pylori eradication was done in patients with proven H. pylori infection. Patients in whom H. pylori eradication therapy was not effective, alternative treatments options including chemotherapy, radiotherapy and surgery, were given.
Results: Fifty two patients with H. pylori infection underwent anti-H. pylori therapy, the total effective rate of anti-H. pylori treatment was 92.3 per cent (48/52). Thirty two patients were given anti-tumour treatment, including chemotherapy, radiotherapy and surgery. The total effective rate was 90.6 per cent (29/32). The five-year overall survival rate and five-year progression-free survival rate were 93.4 and 84.2 per cent, respectively.
Interpretation & conclusions: For patients with early gastric MALT lymphoma, anti-H. pylori treatment may be effective. Patients with poor results of anti-H. pylori treatment need to be treated with anti-tumour therapy.
