1 · What the graph read from it

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.

2 · The registry

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

backgroundPatients with lung cancer frequently develop pleural effusion as the disease progresses. This study evaluated the utility of cell-free DNA (cfDNA) from pleural effusion supernatant in identifying targetable mutations in non-small-cell lung cancer (NSCLC) patients who developed resistance to prior therapies.

methodsWe conducted a multicenter retrospective study involving 95 patients who experienced disease progression after at least one line of treatment and underwent pleural effusion cfDNA next-generation sequencing testing.

resultsInitial routine molecular testing detected various driver mutations in 70 (73.7%) patients, while 26.3% had no detectable driver mutations. Subsequent cfDNA next-generation sequencing identified additional genomic alterations during disease progression, increasing the detection rate for driver mutations from 73.7% to 85.3%. For patients whose disease progressed after treatment with first- or second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, 40.7% developed an acquired EGFR T790M mutation, and showed clinical benefit with subsequent administration of osimertinib. Of the 29 patients who progressed following osimertinib treatment, 14 received osimertinib as a first-line therapy, and 15 received osimertinib as a second-line therapy. MET copy number gain (CNG) was identified in 28.6% of patients receiving first-line osimertinib and was associated with a significantly shorter progression-free survival (PFS) of 12.0 months versus 23.0 months for those without MET CNG [hazard ratio (HR) = 18.68, P = 0.00088]. CNG in MET and KRAS was linked to poorer overall survival. Among the patients for whom second-line osimertinib failed, five acquired the EGFR C797S mutation, and four exhibited MYC CNG. MYC CNG was associated with a median PFS of 8.5 months versus 25.0 months for those without MYC CNG (HR 8.4, P = 0.0046).

conclusionCfDNA sampling from pleural effusion is a less invasive and more effective method for genomic profiling in NSCLC with disease progression, offering valuable insights to guide personalized treatment strategies.
