Purpose of review 

Choosing an optimal treatment in older patients with indolent lymphomas is a challenge for hematooncologists. They must concomitantly treat some potentially curable entities, manage other symptomatic incurable diseases and protect their patients from life-threatening toxicities. Specific recommendations for older patients with different subtypes of marginal zone lymphomas are thus required in terms of treatment and supportive care.

Recent findings 

All the data in the literature agree that the therapeutic approach of older patients with malignant hemopathies should include the appraisal of their life expectancy and of the prognostic factors of their tumor, the evaluation of their physiological and cognitive functions and their socioeconomic environment, and their expectancy in terms of quality of life. Major progresses have, therefore, been achieved in the management of lymphoma patients of 80 years and older.

Summary 

With an optimal ‘geriatric assessment’, most of the recommended treatments are also appropriate in older marginal zone lymphoma patients. Extranodal MALT lymphoma: eradication of the pathogen is a major part of the first-line therapy. Prognosis is excellent in early stages. In advanced stages, observation and anti-CD20 antibodies with or without cytostatic drugs are recommended. Nodal MZL: Usually confined to lymph nodes, bone marrow and peripheral blood, they should be managed as follicular lymphomas. Splenic MZL: in this unique entity involving the spleen, the bone marrow and the peripheral blood. Hepatitis infection should be eradicated before considering treatment. Only symptomatic patients require to be treated by splenectomy and/or anti-CD20 antibodies.
