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

backgroundThere have been many studies that describe the value of diagnostic staging laparoscopy (DSL) in gastric cancer. However, different studies use different indications, making study results difficult to compare. This study aimed to clarify the diagnostic feasibility of DSL for gastric cancer in a prospective manner and investigated the impact of DSL on clinical decision-making in gastric cancer treatment.

methodsThe study was a prospective cohort study based at a single institution between January 2010 and December 2013. We treated 2213 patients with potentially resectable gastric cancer during this period. DSL was primarily indicated for asymptomatic patients with: (1) large Borrmann type 3 tumours ≥8 cm, (2) Borrmann type 4 tumours (linitis plastica), (3) bulky lymph nodes or paraaortic lymph node swelling, or (4) clinical suspicion of peritoneal disease. The primary outcome is change in treatment strategy, and the secondary outcomes are diagnostic accuracy of the indications and false negative rate of DSL.

resultsDSL was performed on 156 (7%) of 2213 patients. Of these, peritoneal disease was found in 74 (47%) patients: (1) 56% for large type 3, (2) 54% for type 4, (3) 21% for bulky lymph nodes or paraaortic lymph node swelling, and (4) 20% for suspected peritoneal disease. The diagnostic accuracy of our indication for DSL was 92% for all patients and 74% for patients with cT3/T4 tumours. Among 82 patients without peritoneal disease, 66 patients (81%) underwent subsequent radical gastrectomy; peritoneal disease was discovered intraoperatively for 7 patients at laparotomy, indicating a false negative rate of 11%.

conclusionWe confirmed that DSL performed according to our indication, in the context of gastric cancer, possesses diagnostic feasibility. Approximately half of the patients who underwent DSL consequently avoided unnecessary laparotomy and were able to receive appropriate alternative treatment.
