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

introductionCentralization of gastric cancer surgery is thought to improve outcome and has been imposed in the Netherlands since 2012. This study analyzes the effect of centralization in terms of treatment outcome and survival in the Eastern part of the Netherlands.

methodsAll gastric cancer patients without distant metastases who underwent a gastrectomy in six hospitals in the Eastern part of the Netherlands between 2008 and 2011 (pre-centralization) and 2013-2016 (post-centralization) were selected from the Netherlands Cancer Registry. Patient and tumor characteristics and treatment outcomes (duration of surgery, blood loss, resection margin, lymphadenectomy, chemotherapy, postoperative complications and hospital stay, and overall and disease-free survival) were analyzed and compared between pre- and post-centralization.

resultsOne hundred forty-four patients were included pre-centralization and 106 patients post-centralization. Patient and tumor characteristics were almost similar in the two periods. After centralization, more patients were treated with perioperative chemotherapy (25 vs. 42% p < 0.01). The proportion of patients treated with an adequate lymphadenectomy (21 vs. 93% p < 0.01) and laparoscopic surgery (6 vs. 40% p < 0.01) increased significantly (p < 0.01). The amount of cardiac complications (16 vs. 7.5% p < 0.05) decreased; however, complications needing a re-intervention were comparable (42 vs. 40% p = 0.79). Median hospital stay decreased from 10 to 8 days (p < 0.01). A 30-day mortality did not differ significantly (4.2 vs. 1.9%). A 1-year overall (78 vs. 80% p = 0.17) and disease-free survival (73 vs. 74% p = 0.66) remained stable. DISCUSSION: Centralizing gastric cancer treatment in the Eastern part of the Netherlands resulted in improved lymph node harvesting and a successful introduction of laparoscopic gastrectomies. Centralization has not translated into improved mortality, and other variables may also have led to these improved outcomes. Further research using a nationwide population-based study will be needed to confirm these data.
