Heterogeneity and prognosis of single organ metastases in gastric cancer.

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
Background: While single organ metastases generally present a more optimistic prognosis compared to multiple metastases, the influence of the specific organ site for single organ metastases on prognosis remains undetermined. This retrospective study aimed to investigate the prognostic differences in late-stage gastric cancer with single organ metastasis. Methods: Data for patients diagnosed with gastric cancer were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database for survival analysis, covering years spanning from 2010 to 2016. Furthermore, Kaplan-Meier survival curves and Cox regression were utilized to analyze overall survival (OS) and disease-specific survival (DSS). Additionally, given the impact of confounders and bias on the results, prognosis was further analyzed using propensity score matching (PSM) and floating absolute risk methods. Results: A cohort comprising 4,297 patients diagnosed with gastric cancer and exhibiting single organ metastasis was hereby enrolled. Liver metastasis was the most common (71% of the total), while brain metastasis accounted for the least (1.7% of the total). Compared to other metastases, patients with bone metastasis presented the worst OS [hazard ratio (HR), 1.319; 95% confidence interval (CI): 1.207-1.442; P<0.001], and this remained consistent even upon the application of floating absolute risk (HR, 1.10; 95% CI: 1.01-1.20) and PSM methods (HR, 1.187; 95% CI: 1.053-1.339; P=0.005). In addition, subgroup analysis and interaction tests of OS revealed an interaction between age (P=0.02), histological type (P=0.002), and bone metastasis. Conclusions: In patients with single organ metastasis of gastric cancer, the prognosis varies by the metastatic site, with bone metastasis presenting the poorest outcome. Overall, this study forges a foundation for further research on the mechanisms and patterns of different metastatic sites in gastric cancer and informs treatment strategies.
