Evaluation of the efficacy and safety of toripalimab combination therapy for treatment of advanced gastric cancer: a meta-analysis.
Review in International journal of clinical and experimental pathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo systematically evaluate the efficacy and safety of combination therapy with toripalimab in the treatment of advanced gastric cancer (GC).
methodsWe conducted a thorough search for relevant studies in PubMed, Embase, Cochrane Library, and Web of Science. Effect estimates were computed utilizing Stata software (version 14.0) and either random or fixed effects models, as applicable. A subgroup analysis was undertaken to assess the effect of various combination therapies on overall response rate (ORR). Begg and Egger's tests were employed to assess publication bias.
resultsThe study consisted of 8 trials, which included 277 participants with advanced gastric cancer. The overall ORR was 41.4% (95% CI, 32.4%-50.3%), with a disease control rate (DCR) of 83.6% (95% CI, 74.6%-92.7%), a median overall survival (mOS) of 11.0 months (95% CI, 9.6-12.4), and a median progression-free survival (mPFS) of 4.2 months (95% CI, 2.5-6.0) for the combination therapy with toripalimab. Subgroup analysis revealed that the combination of toripalimab and chemotherapy achieved a greater ORR compared to the non-chemotherapy group, with ORR rates of 49.8% (95% CI, 42.2%-57.4%) and 31.9% (95% CI, 26.7%-37.1%), respectively. The combination therapy with toripalimab led to adverse events (AEs) of any grade at 94.0% of cases (95% CI, 89.5%-98.5%) and grade 3 AEs at 32.4% (95% CI, 17.8%-47.1%). The sensitivity analysis indicated that no single study affected the overall results.
conclusionsCombination therapy of toripalimab can improve clinical efficacy, although with increased but manageable toxicity. Additional clinical trials are required to assess comprehensively the efficacy and safety of alternative toripalimab regimens. The review agreement has been recorded with PROSPERO (CRD42024585696).
