Marginal B-cell lymphoma: A 10-year retrospective study at national institute of hematology and blood transfusion, Vietnam.

All three subtypes of marginal zone B-cell lymphoma were identified: mucosa-associated lymphoid tissue lymphoma (73.3%), nodal marginal zone lymphoma (20.9%), and splenic marginal zone lymphoma (5.8%).

The most frequently affected extranodal sites were the stomach (25.6%) and eyes (24.4%).

Bone marrow invasion was observed to be 14.8 times more likely in patients with elevated lactate dehydrogenase, 40 times more likely in those with increased B2-M levels, and 4.4 times more likely in those with a Ki67 index > 30%.
