Predictive value of neutrophil-to-lymphocyte ratio combined with carcinoembryonic antigen in postoperative adjuvant chemotherapy after gastric cancer surgery.
Article in World journal of gastrointestinal oncology, 2025. 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
backgroundGastric cancer (GC) is an aggressive malignancy of the gastrointestinal tract characterized by high recurrence rates following radical gastrectomy. To enhance treatment efficacy, reduce recurrence, and improve patient survival, adjuvant chemotherapy is commonly administered based on established postoperative guidelines. Despite advancements in chemotherapy delivery, the overall response rate remains below 50%, primarily due to the lack of targeted therapies tailored to specific patient populations.
aimTo explore sensitive biomarkers to assess the efficacy of postoperative adjuvant chemotherapy in appropriate patient subgroups.
methodsThis study retrospectively analyzed 1628 patients who underwent radical gastrectomy for GC at our hospital in 2017 and 2018, with a subsequent five-year follow-up. Patients were divided based on whether they received postoperative adjuvant chemotherapy. The study aimed to determine optimal cutoff values for various biomarkers-neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 199, CA724, and CA242-using receiver operating characteristic (ROC) curves. Based on the optimal ROC cut-off, a novel combined metric, NLR-CEA, was developed to assess the efficacy of adjuvant chemotherapy following GC surgery.
resultsCox subgroup analysis demonstrated that postoperative adjuvant chemotherapy significantly improved overall survival in the NLR-CEA_Low group with a rate of 0.41 (0.26-0.63). In the NLR-CEA_Middle group, the protective effect was observed at 0.69 (0.54-0.87), while in the NLR-CEA_High group, it was 0.73 (0.53-0.99). Notably, a 32% difference in the efficacy of chemotherapy was observed between the NLR-CEA_Low and NLR-CEA_High groups.
conclusionNLR-CEA is an effective biomarker for evaluating the efficacy of postoperative adjuvant chemotherapy in GC. Patients with NLR-CEA_Low exhibit significantly better responses to chemotherapy compared to those with NLR-CEA_High.
