Reduced Peripheral Blood Natural Killer Cell Proportion Predicts Poor Overall Survival in Advanced Gastric Cancer Patients Treated With Apatinib.
Article in World journal of oncology, 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
Background: Angiogenesis inhibition represents a key therapeutic strategy in oncology, with apatinib showing significant efficacy for advanced gastric cancer (AGC) therapy. Currently, no biomarkers can reliably predict which AGC patients will benefit most from apatinib. The purpose of this study was to evaluate apatinib plus tegafur gimeracil oteracil potassium capsule (S-1) as a second-line therapy in AGC and to investigate prognostic biomarkers associated with outcomes. Methods: All 60 patients received apatinib (250 or 500 mg once daily) in combination with S-1 (40 mg/m Results: Among all 60 evaluable patients, no complete responses were observed. Partial responses were observed in 33.3% (20/60) of patients (95% confidence interval (CI): 21.1-45.6%), stable disease was observed in 38.3% (23/60) of patients (95% CI: 25.7-51.0%), while progressive disease occurred in 28.3% (95% CI: 16.6-40.1%). Notably, patients with NK cell proportions greater than 17% experienced longer progression-free survival (PFS) and overall survival (OS) than those with lower proportions. Conclusions: Apatinib combined with S-1 exhibited favorable tolerability and promising clinical activity as a second-line option for AGC patients. Importantly, we identified peripheral blood NK cell proportion as a potential predictor of treatment response, where a low NK cell proportion correlated with poorer outcomes.
