Oncological outcomes in patients with pT1N0-3 or pT2-3N0 gastric cancer after curative resection without adjuvant chemotherapy.
Article in Langenbeck's archives of surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThe survival outcomes of pT1N0-3 or pT2-3N0 gastric cancer after curative resection are favorable without adjuvant chemotherapy. However, some patients develop recurrence and details of these recurrences remain unclear. This study aimed to evaluate the prognostic factors in patients with pT1N0-3 or pT2-3N0 gastric cancer.
methodsWe retrospectively reviewed the medical records of 1219 patients with pT1N0-3 or pT2-3N0 gastric cancer who underwent curative gastrectomy without neoadjuvant or adjuvant chemotherapy between April 2007 and March 2012 at Cancer Institute Hospital.
resultsThis cohort included 895 pT1N0, 73 pT1N1, 23 pT1N2, 6 pT1N3, 130 pT2N0, and 92 pT3N0 patients. The 5-year overall survival (OS) and 5-year relapse-free survival (RFS) for pT1N0-3 and pT2-3N0 gastric cancer were 98.9% (95% CI 98.1-99.4) and 97.7% (95% CI 96.7-98.4), respectively. Age (HR 3.56, 95% CI 2.10-6.03) and lymphovascular involvement (hazard ratio (HR) 2.98, 95% CI 1.76-5.04) were independent prognostic factors in a multivariate analysis for RFS. The 5-year RFS for patients aged ≥75 years or with lymphovascular involvement were 94.4% (95% CI 89.8-97.0) and 95.1% (95% CI 92.5-96.8), respectively.
conclusionThe survival outcomes of pT1N0-3 and pT2-3N0 were excellent, even in patients with aged >75 years or lymphovascular involvement which were risk factors. However, the sample size of T1N3 gastric cancer is small, so larger sample size and risk factor analysis are required.
