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

backgroundThe oncological efficacy of laparoscopic surgery for advanced gastric cancer (AGC) has been evaluated by several randomized trials. However, the inclusion of earlier-stage disease was a limitation in previous studies.

methodsPatients with cT3-4 gastric cancer, determined by surgical staging to minimize migration of earlier stages, treated at a tertiary cancer center from 2009 to 2018 were included. Based on the surgical approach, the patients were divided into two groups: the laparoscopic gastrectomy (LG) and the open gastrectomy (OG) and matched for age, sex, macroscopic appearance (type 4 or non-type 4), body mass index, estimated tumor size, clinical stage T3'T4, clinical N stage, pathologic T stage (T3 or T4), and type of surgery (total or distal gastrectomy).

results588 patients (221 LG, 367 OG) were included in the analysis. After 1:1 propensity-score matching, 386 patients (193 LG, 193 OG) were assigned for analysis. In the LG group, operation time was longer with lower blood loss. The incidence of postoperative complications (≥ grade III) did not differ significantly between the groups (OG: 8.3%, vs. LG: 9.3%). Overall survival (OS) was longer in the LG group (5-year OS: 79.3 vs. 73% HR 0.66, 95% CI 0.44-0.99, P = 0.0497). Relapse-free survival (RFS) did not show a statistical difference (5-year RFS: 69.5 vs. 68.7 HR 0.88, 95% CI 0.62-1.26, P = 0.487). Subgroup analysis for OS also demonstrated equivalent outcomes.

conclusionLG demonstrates comparable safety and efficacy to OG for advanced gastric cancer at surgical staging, with similar rates of severe complications and long-term oncological outcomes. Further research is needed to validate these findings, particularly for total gastrectomy and for patients from Western populations.
