Comparison of perioperative and histopathologic outcomes among neoadjuvant treatment strategies for locoregional gastric cancer.
Article in Journal of surgical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesNeoadjuvant chemotherapy (NAC) and chemoradiation (NCRT) have demonstrated improved survival for gastric cancer. However, the optimal neoadjuvant treatment remains unclear. We sought to evaluate perioperative and histopathologic outcomes among neoadjuvant treatments for locoregional gastric cancer.
methodsThe National Cancer Database queried patients who received NAC or NCRT followed by resection for T2-T4 and/or node-positive gastric cancer (2006-2018). Logistic and Poisson regression assessed perioperative (30-day readmission, 30- and 90-day mortality, length of stay [LOS]) and histopathologic outcomes (pathologic complete response [PCR], margin status, and negative pathologic lymph nodes [ypN0]). Kaplan-Meier methods and Cox regression assessed overall survival (OS).
resultsOf 9831 patients, 4221 (42.9%) received NAC and 5610 (57.1%) NCRT. There were no differences in perioperative outcomes, apart from patients treated with NCRT exhibiting increased LOS (incidence rate ratio 1.09, 95% confidence interval [CI] 1.03-1.16). Patients who received NCRT were more likely to achieve PCR, margin-negative resection, and ypN0 (all p < 0.05). Median OS was 36.8 months for NAC and 33.6 months for NCRT (p < 0.001). NCRT independently predicted worse OS (vs. NAC, hazard ratio 1.10, 95% CI 1.03-1.18).
conclusionNCRT was associated with better histologic tumor response although NAC was associated with improved OS. Better understanding prognostication through histologic assessment following neoadjuvant therapy is needed.
