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

purposeTo prepare and evaluate a new radiotracer for molecular imaging of cell surface receptors for epidermal growth factor (EGF).

methodsCys-tagged EGF (cEGF) was labeled with (18)F by coupling the free thiol group of the Cys tag with N-[2-(4-[(18)F]fluorobenzamido)ethyl]maleimide ([(18)F]FBEM) to form [(18)F]FBEM-cEGF. Cell uptake, internalization and efflux of [(18)F]FBEM-cEGF were tested in human head and neck squamous carcinoma UM-SCC1 cells. In vivo tumor targeting and pharmacokinetics of the radiotracers were evaluated in UM-SCC1 tumor-bearing athymic nude mice by static and dynamic microPET imaging. Ex vivo biodistribution assays were performed to confirm the noninvasive imaging results.

resultsThe radiolabeling yield for [(18)F]FBEM-cEGF was over 60%, based on starting [(18)F]FBEM. [(18)F]FBEM-cEGF exhibited rapid blood clearance through both hepatobiliary and renal excretion. UM-SCC1 tumors were clearly visualized and showed modest tracer uptake of 2.60 ± 0.59 %ID/g at 30 min after injection. Significantly higher tumor uptake of [(18)F]FBEM-cEGF (5.99 ± 1.61%ID/g at 30 min after injection, p < 0.01) and tumor/nontumor ratio were achieved by coinjection of 50 μg of unlabeled EGF. Decreased liver uptake of [(18)F]FBEM-cEGF was observed when unlabeled EGF was coadministered.

conclusionWith optimized liver blocking, [(18)F]FBEM-cEGF has the potential to be used in a noninvasive and quantitative manner for detection of malignant lesions and evaluation of EGFR activity.
