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

Background: The analysis of the gene copy number alterations in tumor samples are increasingly used for diagnostic and prognostic purposes in patients with gastric cancer (GC). However, these procedures are not always applicable due to their invasive nature. In this study, we have analyzed the copy number alterations of five genes (HER2, MDM2, c-MYC, c-MET, and TP53) with a fixed relevance for GC in the circulating tumor cells (CTCs) of GC patients, and, accordingly, as a potential approach, evaluated their usage to complete primary tumor biopsy. Methods: We analyzed the status of the copy number alterations of the selected genes in CTCs and matched biopsy tissues from 37 GC patients using fluorescence in situ hybridization. Results: HER2 amplification was observed in 2 (5.41%) samples. HER2 gene status in CTCs showed a strong agreement with its status in 36 out of 37 patients’ matched tissue samples (correlation: 97.29%; Kappa: 0.65; p < 0.001). MDM2 amplification was found only in 1 (2.70%) sample; however, the amplification of this gene was not detectable in the CTCs isolated from this patient. c-MYC amplification was observed in 3 (8.11%) samples, and the status of its amplification in the CTCs indicated a complete agreement with its status in the matched tissue samples (correlation: 100%; Kappa: 1.0). Conclusion: Our work suggests that the amplification of HER2 and c-MYC is in concordance with the CTCs and achieved biopsies, and, consequently, CTCs may act as a non-invasive alternative for recording the amplification of these genes among GC patients.
