Expression of Prostate-Specific Membrane Antigen in Salivary Gland Tumors.

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
introductionProstate-specific membrane antigen (PSMA) is a key diagnostic/prognostic, therapeutic target in prostate cancer. While PSMA expression is well established in prostate cancer, its expression is also observed in non-prostatic tissues and other tumors. PSMA expression is observed in salivary gland tumors (SGTs); however, its expression pattern is not well established. This study assessed the distribution of PSMA expression in SGT specimens.
methodsThis study retrospectively analyzed archived SGT specimens. Patient records were reviewed and their formalin-embedded tumor blocks were retrieved from the pathology department files. Immunohistochemical staining and examination was performed using an antibody directed against PSMA to assess expression levels in 243 salivary gland specimens containing 126 specimens of malignant and 117 specimens of benign SGTs. PSMA staining was quantified using a modified immunohistochemical scoring method (H score; range 0-300).
resultsPSMA expression was observed in both benign SGTs and malignant SGTs; however, PSMA expression in malignant SGTs was higher than in benign SGTs. PSMA was expressed in 94% (118/126) of malignant SGTs (represented as average histochemical [H
conclusionThis study demonstrated that PSMA is commonly expressed in malignant SGTs, suggesting that PSMA could be effective for targeted imaging and therapeutics in these tumor types.
