Patients with metastatic uveal melanoma (mUM) have a poor prognosis, and few appropriate medications are available. Tebentafusp is approved by the Food and Drug Administration for mUM recently. However, the real efficacy and safety of tebentafusp are still unclear. We searched PubMed, Embase, and Cochrane Library from inception to March 20, 2024. The research was reported based on the preferred reporting items for systematic reviews and meta-analysis guidelines. We used random effects models to aggregate data on the response rates and adverse events of tebentafusp therapy. Six studies met the inclusion criteria with a total sample of 589 participants. The pooled objective response rate was 0.08 (95% CI: 0.05-0.12), and pooled disease control rate was 0.51 (95% CI: 0.44-0.57). The overall incidence was 0.99 (95% CI: 0.95-1.00) for any grade adverse events, 0.50 (95% CI: 0.41-0.59) for grade 3-4 adverse events, and 0.01 (95% CI: 0-0.03) for discontinuation due to adverse events. Tebentafusp exhibits promising treatment outcomes for mUM patients. Although accompanied with a common occurrence of adverse events, which can typically be managed and controlled. Future research is necessary for substantiating these findings and refining guidelines for management of mUM.

Metastatic uveal melanoma (mUM) is a rare disease associated with poor prognosis and limited therapeutic options. Recent studies showed that detecting ctDNA is feasible and can aid treatment decisions for patients with mUM. We systematically searched PubMed, EMBASE, and Cochrane databases for eligible studies published up to May 2025 that included patients with mUM and reported data on the association between ctDNA and survival outcomes (OS and PFS). Statistical analyses were performed using Review Manager 5.4 software. Of the initial 450 records, seven studies met eligibility, including 518 patients with mUM. At baseline, ctDNA positivity was associated with significantly worse PFS (HR 2.34; 95% CI 1.56-3.51; p 2 = 0%) and OS (HR 3.32; 95% CI 2.09-5.29; p 2 = 48%). In patients treated with tebentafusp, ctDNA clearance was associated with superior OS (HR 0.19; 95% CI 0.07-0.49; p 2 = 46%) and any decrease in ctDNA was associated with better OS (HR 0.42; 95% CI 0.22-0.80; p 2 = 0%). This meta-analysis underscores ctDNA as a potential predictor of worse survival in patients with mUM, highlighting its potential to refine risk stratification and guide treatment strategies.
