Prognostic significance of intratumoral neutrophil extracellular traps in pulmonary pleomorphic carcinoma: comparison with adenocarcinoma.
Article in BJC reports, 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
backgroundPleomorphic carcinoma (PC) of the lung is a rare, aggressive non-small cell lung cancer. Neutrophil extracellular traps (NETs) are linked to tumour progression, but their relevance in pulmonary PC is unknown. We evaluated the prognostic impact of intratumoral NETs and CD66b
methodsAmong 1148 patients who underwent pulmonary resection for primary lung cancer, 813 patients with adenocarcinoma and 17 with PC were analysed. Clinicopathological factors and survival were compared and propensity score matching was applied. NETs and neutrophils were quantified by CD66b immunohistochemistry and citrullinated histone H3/myeloperoxidase immunofluorescence.
resultsPC was associated with heavier smoking, more vascular invasion, and more advanced stage than adenocarcinoma (all p < 0.001). The patient characteristics were comparable after matching. Overall and recurrence-free survival were both worse in the PC group (both p < 0.001) and remained poorer after matching. Cox analysis identified NET-positive area (% per high-power field) as an independent predictor of worse overall survival (hazard ratio 1.14, 95% confidence interval 1.01-1.30; p = 0.033).
conclusionsPulmonary PC shows intense neutrophil infiltration and abundant intratumoral NETs, both associated with poor survival. Quantitative assessment of NETs may serve as a biomarker and therapeutic target in PC.
