Treatment of Stage IE / Stage IIE Primary Pulmonary Diffuse Large B-Cell Lymphoma (DLBCL)
Primary pulmonary lymphoma (PPL) presenting at stage IE or stage IIE as diffuse large B-cell lymphoma (DLBCL) represents a distinct clinical scenario within pulmonary lymphomas, and the evidence-based treatment approach for this subtype differs from that of other PPL subtypes.
Clinical scenario
Stage IE or stage IIE primary pulmonary DLBCL — disease localised to the lung, with or without regional nodal involvement. Evidence supports a surgical approach specifically for this histological subtype; this recommendation does not extend to stage IE/IIE MALT lymphoma, other non-Hodgkin lymphomas, or Hodgkin lymphoma arising in the lung.
Treatment approach (partial overview)
The structured protocol for stage IE/IIE primary pulmonary DLBCL incorporates surgical resection of the pulmonary lesion together with chemotherapy. The specific surgical approach, extent of resection, sequencing, and full chemotherapy details are defined within the complete evidence-based regimen — access it below.

- Based on our findings, surgery should be recommended for stage IE/IIE DLBCL, but not for stage IE/IIE MALT lymphoma, other NHL, or HL.
- Surgical intervention should be considered as part of the treatment strategy for stage IE/IIE DLBCL, potentially improving survival outcomes.
- This is consistent with results from a clinical trial on intestinal DLBCL, where surgery plus chemotherapy yielded higher complete response rates (85.3%) and lower relapse rates (15.3%) compared to chemotherapy alone (complete response rate 64.4%, relapse rate 36.8%).
- Our analysis demonstrated similar findings for PPLs, as sublobectomy provided outcomes comparable to lobectomy/pneumonectomy for both stage IE and IIE PPLs, both before and after PSM.
- In other words, limited resection was allowed if complete resection was achieved.
- Besides, if limited resection led to positive surgical margins, following chemotherapy could deal with this trouble which may not alter the survival.
