Survival benefits of postoperative adjuvant chemotherapy in adults aged ≥ 80 years with locally advanced gastric cancer: insights from a population-based study.

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 AND
aimsPostoperative adjuvant chemotherapy in older adults aged ≥ 80 years with locally advanced gastric cancer (LAGC) remains debated owing to concerns over treatment tolerance and limited data. We aimed to assess the effectiveness of postoperative adjuvant chemotherapy in adults aged ≥ 80 years with LAGC using data from the Surveillance, Epidemiology, and End Results database. METHODS AND
resultsA total of 2395 patients with LAGC aged ≥ 80 years who underwent radical surgery between 2004 and 2015 were identified. Propensity score matching (1:1) was applied to pair 422 patients receiving adjuvant chemotherapy with 1973 patients who underwent surgery alone. Multivariate logistic regression identified independent predictors of adjuvant chemotherapy, including the period from 2012-2015, pN1-2 and pN3 stages, and radiation therapy. Conversely, age ≥ 85 years predicted decreased chemotherapy use. Cancer-specific survival (CSS) and overall survival (OS) were compared using multivariate Cox analysis, showing significantly longer OS and CSS in the adjuvant chemotherapy group, before and after matching. Subgroup analysis revealed that patients aged 80-84 years and those with N + stages benefited most from adjuvant chemotherapy, whereas patients aged ≥ 90 years did not show significant benefit.
conclusionPostoperative adjuvant chemotherapy should be considered for patients aged ≥ 80 years with LAGC, especially those with lymph node involvement, as it offers significant survival benefits. However, as age approaches 90 years, the benefits of adjuvant chemotherapy may diminish, warranting more cautious application.
