What Is the Treatment of Stage IE or IIE Primary Pulmonary MALT Lymphoma?

Primary pulmonary lymphoma arising from mucosa-associated lymphoid tissue (MALT) at stage IE or IIE represents a localised extranodal presentation. The management approach in this setting is guided by symptom status and disease extent.

Clinical Scenario

Stage IE or stage IIE primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma — disease confined to the lung(s), with or without involvement of regional lymph nodes.

Management Approach

For asymptomatic, localised disease, a non-interventional initial strategy is recommended by international guidelines. Surgical intervention is not a standard first step — it has a specifically defined, limited role in selected circumstances. The complete evidence-based decision pathway, including the full criteria for each approach, is available below.

Some guidelines, such as those from Italy, recommend a "watch and wait" approach for asymptomatic localized MALT PPLs.
Given these considerations, surgery should primarily be reserved for diagnostic purposes or in cases where local complications, such as airway obstruction or bleeding, necessitate surgical intervention.
