The impact of PD-L1 polymorphisms on the efficacy of immune checkpoint inhibitors depends on the tumor proportion score: a retrospective study.
Article in Journal of cancer research and clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeThis study aims to clarify the relationship between rs2282055, a single-nucleotide polymorphism (SNP) in programmed death-ligand 1 (PD-L1), and TPS. Polcaro et al. (2024) showed that rs822336, a SNP in PD-L1, predicts the effect of immune checkpoint inhibitors (ICIs). However, the study did not show a relationship between rs822336 and the tumor proportion score (TPS), which is currently used as a primary marker. Therefore, we examined this relationship.
methodPatients treated with immune checkpoint inhibitor monotherapy for non-small cell lung cancer at Kyoto University Hospital until January 2023, with TPS data and biological specimens available for SNP measurement, were eligible for this study. Genomic DNA was extracted from peripheral blood leukocytes. We used rs2282055, which is in linkage disequilibrium with rs822336, instead of rs822336, because of its distribution in the Asian patient population. We retrospectively extracted data on age, sex, smoking history, driver mutations, TPS, progression-free survival (PFS), and best response to ICI from medical records.
resultThe rs2282055 T/T genotype was associated with significantly better PFS in the TPS-negative population than in the other genotypes. In contrast, no differences were observed in TPS-positive patients.
conclusionThe rs2282055 genotype may help in selecting cases from the TPS-negative patient population that may benefit from ICI therapy.
