Specific Detection of Prostate Cancer Cells in Urine by RNA In Situ Hybridization.
Article in The Journal of urology, 2021. 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
purposeNoninvasive tests that can accurately detect prostate cancer are urgently needed for prostate cancer diagnosis, surveillance and prognosis. Exfoliated prostate cells captured in urine represent a promising resource for noninvasive detection of prostate cancer. We investigated performance of a novel cell-based urine test for detection of clinically significant prostate cancer. MATERIALS AND
methodsWe previously developed a multiplex RNA in situ hybridization assay targeting NKX3-1, PRAC1 and PCA3 that enables identification and quantification of malignant and benign prostate cells released into urine. We investigated application of the assay for prostate cancer detection in a cohort of 98 patients suspected of harboring prostate cancer. Urine was collected following digital rectal examination, and the sediment was isolated and evaluated by RNA in situ hybridization. Samples were scored based on cellular expression of RNA in situ hybridization targets. Cells of prostate origin were defined by positivity for NKX3-1 and/or PRAC1, and prostate cancer cells by positivity for PCA3.
resultsProstate cells (NKX3-1/PRAC1+ cells) were detected in 69 samples, among which 20 were positive for PCA3 (ie positive for prostate cancer cells). Comparison of RNA in situ hybridization results with biopsy outcome and clinical variables revealed that positivity for cancer by RNA in situ hybridization significantly correlated with intermediate/high risk cancer (p=0.003), PSA density (p=0.022), significant disease (p <0.0001) and Gleason score (p=0.003). The test was 95% specific and 51% sensitive for detection of clinically significant prostate cancer.
conclusionsIdentification of exfoliated prostate cancer cells in urine by RNA in situ hybridization provides a novel tool for highly specific and noninvasive detection of prostate cancer.
