Human epidermal growth factor receptor 2 (Her-2) and S-1 adjuvant chemotherapy in stage 2/3 gastric cancer patients who underwent D2 gastrectomy.

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.
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
purposesThe trastuzumab for Gastric Cancer study newly defined tumors that were positive for human epidermal receptor-2 (Her-2) and created a Her-2-oriented treatment strategy that is also applicable in the adjuvant setting for stage 2/3 cancers. However, there is currently no information available on the rate of Her-2 positivity and the relapse-free survival (RFS) stratified by Her-2 status in stage 2/3 patients.
methodsThe Her-2 status, defined by the current standard method, was examined in 100 gastric cancer patients who underwent curative D2 surgery, who were pathologically diagnosed with stage 2/3 cancer, and received adjuvant S-1 chemotherapy between June 2002 and December 2011.
resultsTen of the 100 patients were Her-2 positive. Her-2-positive status was more frequently seen in tumors with a differentiated histology. The 5-year RFS rate was 56.3 % in Her-2-positive cases, and 48.8 % in Her-2 negative cases, which was not significantly different (P = 0.786).
conclusionsThe Her-2-positive rate for stage 2/3 gastric cancer patients was low, at only 10 %. Although the RFS was not significantly different based on the Her-2 status, the low positive rate made interpretation difficult. A multi-center study with a large sample size is necessary to clarify the prognostic impact of Her-2 in stage 2/3 gastric cancer patients.
