MET pathway inhibition increases chemo-immunotherapy efficacy in small cell lung cancer.
Article in Cell reports. Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The introduction of immunotherapy as a first-line treatment for advanced small cell lung cancer (SCLC) represents significant progress, yet there remains an opportunity to further improve patient outcomes. Hepatocyte growth factor (HGF) receptor (MET) pathway activation promotes epithelial-mesenchymal transition, driving chemoresistance and potentially impairing the efficacy of immunotherapy. In SCLC mouse models, adding MET inhibition to chemo-immunotherapy (anti-PD-L1) reduces tumor growth, extends survival, and reshapes the tumor microenvironment by decreasing suppressive myeloid cell infiltration and enhancing the immune response. Analysis of pretreatment human SCLC tumor samples reveals that myeloid-enriched immune infiltrates may contribute to chemo-immunotherapy resistance. Elevated serum HGF levels are associated with a mesenchymal and inflamed phenotype, suggesting that patients with these characteristics might benefit from MET inhibitor-based therapeutic strategies. These findings provide strong preclinical and translational evidence supporting MET inhibition as a therapeutic approach to overcome treatment resistance, enhancing the immune response and improving outcomes in biomarker-defined subsets of SCLC patients.
