Impact of Tregs on tumor regression in locally advanced G/GEJ cancer patients undergoing neoadjuvant chemoimmunotherapy.
Article in Scientific reports, 2025. 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
Neoadjuvant chemoimmunotherapy has transformed the treatment of locally advanced gastric or gastroesophageal junction (G/GEJ) cancer. However, identifying reliable predictive markers for treatment efficacy remains challenging. We conducted a retrospective analysis to evaluate the prognostic value of peripheral blood regulatory T (Treg) cells in patients with G/GEJ cancer undergoing neoadjuvant chemoimmunotherapy followed by curative resection. From July 2020 to May 2023, 79 patients met the inclusion criteria. All patients achieved R0 resection following D2 radical surgery, with 26.6% exhibiting a pathological complete response (pCR). Significant differences in Treg cells, T/Treg ratios, and CD4+/Treg ratios were observed between patients with pCR and those without after one treatment cycle (P = 0.0054, 0.0489, and 0.0434, respectively). Patients were categorized based on changes in Treg cell counts post-treatment, revealing a higher pCR rate in those with reduced Treg cells (P = 0.014). Changes in Treg cell counts after one cycle of neoadjuvant chemoimmunotherapy serve as a promising predictive marker for pCR in locally advanced G/GEJ cancer patients. This finding supports the development of personalized treatment strategies, enhancing outcomes in this challenging clinical landscape.
