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

Nitric oxide (NO(*)) has many characteristics including cytotoxicity, radiosensitization and anti-angiogenesis, which make it an attractive molecule for use in cancer therapy. We have investigated the use of iNOS gene transfer, driven by both a constitutive (CMV) and X-ray inducible (WAF1) promoter, for generating high concentrations of NO(*) within tumour cells. We have combined this treatment with radiation to exploit the radiosensitizing properties of this molecule. Transfection of murine RIF-1 tumour cells in vitro with the iNOS constructs resulted in increased iNOS protein levels. Under hypoxic conditions cells were radiosensitized by delivery of both constructs so that these treatments effectively eliminated the radioresistance observed under hypoxic conditions. In vivo transfer of the CMV/iNOS construct by direct tumour injection resulted in a delay (4.2 days) in tumour growth compared with untreated controls. This was equivalent to the effect of 20 Gy X-rays alone. Combination of CMV/iNOS gene transfer with 20 Gy X-rays resulted in a dramatic 19.8 day growth delay compared with controls. Tumours treated with the CMV/iNOS showed large areas of necrosis and abundant apoptosis. We believe that iNOS gene transfer has the potential to be a highly effective treatment in combination with radiotherapy.
