Prognostic significance of splenectomy during completion total gastrectomy in patients with remnant gastric cancer: propensity score matching analysis.
Article in Korean journal of clinical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: Splenectomy for patients with remnant gastric cancer has been controversial. The purpose of this study is to identify the impact of splenectomy in the treatment of remnant gastric cancer. Methods: We retrospectively analyzed 285 patients with remnant gastric cancer who underwent completion total gastrectomy with or without splenectomy in Samsung Medical Center, between September 1996 and December 2017. We used a 1:1 propensity score matching method for the analysis. The matching factors were age, sex, and pathologic stage. After the matching process, we compared the 5-year overall survival (OS) and the disease-free survival (DFS) between patients with and without splenectomy during completion total gastrectomy. Results: The median duration of follow-up was 58.0 months (range, 0-132 months). After propensity score matching, there were no statistically significant differences between the splenectomy group (n=77) and no splenectomy group (n=77) in terms of clinicopathological features. The 5-year OS rate between the no splenectomy and splenectomy group were not significantly different. There was no significant difference between 5-year DFS of the matched groups. Multivariate analysis revealed that splenectomy is not a significant prognostic factor in terms of 5-year OS (no splenectomy vs. splenectomy; 61.5% vs. 60.2%, P=0.884) or DFS (74.9% vs. 69.8%, P=0.880). Conclusion: Splenectomy has no impact on the OS and DFS in patients with remnant gastric cancer. Splenectomy during completion total gastrectomy may not be necessary.
