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

Molecular imaging of a suicide transgene's expression will aid the development of efficient and precise targeting strategies, and imaging for cancer cell viability may assess therapeutic efficacy. We used the PET reporter probe, 9-(4-[18F]fluoro-3-(hydroxymethyl)butyl)guanine ([18F]FHBG) to monitor the expression of a mutant Herpes Simplex Virus 1 thymidine kinase (HSV1-sr39tk) in C6 glioma tumors implanted subcutaneously in nude mice that were repetitively being treated with the pro-drug Ganciclovir (GCV). [18F]-Fluorodeoxyglucose ([18F]FDG), a metabolic tracer, was used to assess tumor cell viability and therapeutic efficacy. C6 glioma tumors stably expressing the HSV1-sr39tk gene (C6sr39) accumulated [18F]FHBG prior to GCV treatment. Significant declines in C6sr39 tumor volumes and [18F]FHBG and [18F]FDG accumulation were observed following 2 weeks of GCV treatment. However, 3 weeks after halting GCV treatment, the tumors re-grew and [18F]FDG accumulation increased significantly; in contrast, tumor [18F]FHBG concentrations remained at background levels. Therefore, [18F]FHBG can be used to detect tumors expressing HSV1-sr39tk, susceptible to regression in response to GCV exposure, and the effectiveness of GCV therapy in eradicating HSV1-sr39tk-expressing cells can be monitored by [18F]FHBG scanning. [18F]FHBG and [18F]FDG imaging data indicate that exposure of C6sr39 tumors to GCV causes the elimination of [18F]FHBG-accumulating C6sr39 cells and selects for re-growth of tumors unable to accumulate [18F]FHBG.
