High-Sensitivity PD-L1 Staining Using Clone 73-10 Antibody and Spatial Transcriptomics for Precise Expression Analysis in Non-Tumorous, Intraepithelial Neoplasia, and Squamous Cell Carcinoma of Head and Neck.
Article in Head and neck pathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeWhile immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 axis have improved outcomes in head and neck squamous cell carcinoma (HNSCC), eligibility criteria based on immunohistochemistry (IHC) target PD-1 solely. We aimed to evaluate the PD-L1 (CD274) expression using highly sensitive clone 73 - 10 and spatial transcriptomics (ST) analysis to elucidate the role of PD-L1 in HNSCC and thus potentially expand the pool of eligible patients.
methodsImmunohistochemical staining of 73 - 10, CD3, CD4, and CD8 were performed in 94 HNSCC clinical samples along with paired adjacent squamous intraepithelial neoplasm (SIN) and normal oral mucosa (NOM) samples. The 73 - 10 positivity was evaluated using a tumor cell score ≥ 1%, and the results were analyzed against clinicopathological features including CD4
resultsThe 73 - 10 detected-PD-L1 positivity was high in HNSCC (79%) compared to SIN (10%) and NOM (3%). 73 - 10
conclusionClone 73 - 10 is a relatively suitable candidate for identifying patients with PD-L1 expression eligible for ICI therapy. It demonstrates high sensitivity in detecting PD-L1 (CD274) in HNSCC, offering immunological and prognostic insights.
