Pulmonary Pleomorphic Carcinoma With Mesenchymal-Epithelial Transition Factor (MET) Mutation: An Aggressive Entity.
Article in Cureus, 2025. 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
Pulmonary pleomorphic carcinoma (PPC) is a rare, aggressive non-small cell lung cancer (NSCLC) subtype characterized by rapid progression and challenging diagnosis from a limited biopsy. These challenges delay treatment initiation. Comprehensive genomic panel profiling helps identify actionable driver mutations, such as mesenchymal-epithelial transition factor (MET) exon 14 skipping mutations, enabling molecular targeted therapy planning. We present a case of an older female patient with suspected NSCLC and rapid clinical deterioration, where biopsy did not confirm the specific subtype. Genotype testing identified a MET exon 14 skipping mutation. A MET inhibitor treatment was planned; however, the patient died before treatment began. Postmortem autopsy confirmed the diagnosis of PPC. This case highlights the importance of early comprehensive genomic profiling in suspected NSCLC with inconclusive histology based on a fine-needle biopsy (FNB) to facilitate timely and potentially beneficial therapeutic planning in rapidly progressing malignancies such as PPC.
