On-treatment dynamics of circulating extracellular vesicles in the first-line setting of patients with advanced non-small cell lung cancer: the LEXOVE prospective study.
Article in Molecular oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Extracellular vesicle (EV) monitoring can complement clinical assessment of cancer response. In this study, patients with advanced non-small cell lung cancer (NSCLC) undergoing osimertinib, alectinib, pembrolizumab or platinum-based chemotherapy ± pembrolizumab were enrolled. EVs were characterized using Bradford assay to quantify the circulating cell-free EV protein content (cfEV), and dynamic light scattering to assess Rayleigh ratio excess at 90°, z-averaged hydrodynamic diameter and polydispersity index. A total of 135 plasma samples from 27 patients were collected at baseline (T0) and at the first radiological restaging (T1). A ∆cfEV < 20% was associated with improved median progression-free survival (mPFS) in responders versus non-responders. Specifically, cfEV responders on pembrolizumab had a significantly better mPFS (25.2 months) compared to those on chemotherapy plus pembrolizumab (6.1 months). EGFR-positive cfEV responders also experienced longer mPFS compared to cfEV non-responders (35.1 months, 95% CI: 14.9-35.5 vs. 20.8 months, 95% CI: 11.2-30.4). This study suggested that monitoring circulating EV could provide valuable insights into treatment efficacy in NSCLC, particularly for patients receiving pembrolizumab or osimertinib.
