Toripalimab in Esophageal Cancer: A Systematic Review and Meta-Analysis.
Synthesis in Journal of gastrointestinal cancer, 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
backgroundEsophageal cancer (EC) remains a highly aggressive malignancy with a poor prognosis despite advancements in treatment. Toripalimab, a PD-1 inhibitor, has demonstrated the potential to improve clinical outcomes. This systematic review and meta-analysis assess the efficacy and safety of Toripalimab in EC.
methodsFollowing PRISMA 2020 guidelines, we conducted a systematic review and meta-analysis, searching PubMed, Embase, Scopus, ScienceDirect, and Google Scholar up to January 2025. Eligible studies evaluated Toripalimab in esophageal cancer, including randomized controlled trials and non-randomized controlled trials. Primary outcomes included overall survival (OS), progression-free survival (PFS), and objective response rate (ORR), while safety outcomes assessed treatment-related adverse events. Data were synthesized using random-effects models, with heterogeneity evaluated via Cochrane's Q and I
resultsThe pooled analysis included six studies involving 678 patients. Toripalimab demonstrated promising efficacy, with a Complete Response (CR) rate of 33%, Partial Response (PR) rate of 36%, pathological complete response (pCR) rate of 30%, and major pathological response (MPR) rate of 46%. The R0 resection rate was 87%, while OS and PFS rates were reported at 78% and 50%, respectively. Anemia (56%), alopecia (54%), leukopenia (54%), and fatigue (30%) were the most frequently reported adverse effects. Other common adverse effects included nausea (29%), constipation (18%), and vomiting (20%).
conclusionsToripalimab demonstrates significant potential in treating esophageal cancer, with favorable response rates and survival outcomes. However, the high incidence of adverse effects highlights the need for supportive care and ongoing research. While based on limited sample sizes and single-arm studies that may introduce bias and affect generalizability in this review, we provide valuable preliminary insights into toripalimab's potential, highlighting the need for larger randomized trials to build on these findings.
