1 · What the graph read from it

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.

2 · The registry

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

purposeAs hypoxia is believed to play an important role in the development and progression of prostate cancer, we evaluated whether 18F-labeled fluoroazomycin arabinoside (18F-FAZA) would be useful to identify tumor hypoxia in resectable prostate cancer.

methodsPositron emission tomography (PET)/CT was performed on 14 patients with untreated localized primary prostate cancer 3 h post-injection of approximately 390 MBq of 18F-FAZA using forced diuresis to decrease radioactivity in the urinary bladder. Anatomical trans-pelvic coil and pre- and post-contrast 1.5 T MRI with endorectal coil were performed on the same day. Patients underwent radical prostatectomy and ex vivo 3 T MRI of the prostatectomy specimen within 14 days following in vivo imaging. Imaging results were verified by whole mount histopathology plus tissue microarray (TMA) immunohistochemical (IHC) analysis for carbonic anhydrase IX (CAIX) and hypoxia-inducible factor 1α (HIF-1α). Registration of in vivo imaging with histology was achieved using mutual information software and performing ex vivo MRI of the prostatectomy specimen and whole mount sectioning with block face photography as intermediate steps.

resultsWhole mount histology identified 43 tumor nodules, 19 of them larger than 1 ml as determined on coregistered volumes featuring 18F-FAZA, MRI, and histological 3-D image information. None of these lesions was found to be positive for CAIX or visualized by 18F-FAZA PET/CT while IHC for HIF-1α showed variable staining of tumor tissues. Accordingly, no correlation was found between 18F-FAZA uptake and Gleason scores.

conclusionOur data based on 18F-FAZA PET/CT and CAIX IHC do not support the presence of clinically relevant hypoxia in localized primary prostate cancer including high-grade disease. Activation of HIF-1α may be independent of tissue hypoxia in primary prostate cancer.
