Coexistence of diffuse large B-cell lymphoma and lung adenocarcinoma in one lymph node: a case report and literature review.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Older men demonstrate heightened susceptibility to both diffuse large B-cell lymphoma (DLBCL) and lung adenocarcinoma. Nevertheless, synchronous presentation of DLBCL and adenocarcinoma within the same lymph node remains exceptionally rare. A 70-year-old Chinese man presented with a 1-year history of a productive cough with white sputum, progressive shortness of breath, and chest tightness. The patient received four cycles of R-CHOP immunochemotherapy directed at the DLBCL. Cervical lymphadenopathy decreased markedly after treatment, and no obvious lymphoma progression was documented during the 5-month follow-up. No specific treatment was administered for the lung adenocarcinoma. This unusual coexistence of DLBCL and metastatic carcinoma poses a significant diagnostic challenge, underscoring the critical need for precise early histopathological evaluation to guide optimal therapeutic intervention.
