Atezolizumab plus bevacizumab in patients with unresectable or metastatic mucosal melanoma: 3-year survival update and multi-omics analysis.
Trial report in Clinical and translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundAtezolizumab plus bevacizumab has shown promising efficacy in advanced mucosal melanoma in the multi-centre phase II study. This report updates 3-year survival outcomes and multi-omics analysis to identify potential response biomarkers.
methodsForty-three intention-to-treat (ITT) patients received intravenous administration of atezolizumab and bevacizumab every 3 weeks. Available samples underwent whole exome sequencing, transcriptome sequencing and targeted bisulphite sequencing to assess correlations with clinical outcomes.
resultsWith a median follow-up of 40.3 months, the median overall survival (mOS) was 23.7 months (95% confidence interval [CI], 15.1-34), and the 3-year OS rate was 28.7% (95% CI, 17.6%-46.8%). Patients with upper site melanoma exhibited longer progression-free survival (PFS), higher tumour neoantigen burden (TNB) and greater copy number variations (CNVs) burden compared to those with lower site melanoma. NRAS mutations were associated with enhanced angiogenesis, with five of six patients achieving partial response. Inflammatory cell infiltration, angiogenic status and activation of the SMAD2 and p38 MAPK pathways may be prognostic indicators.
conclusionsThis 3-year updated analysis confirms the sustained efficacy of atezolizumab in combination of bevacizumab in patients with advanced mucosal melanoma. Inflammatory cell infiltration and angiogenic status were associated with therapeutic response. Furthermore, mucosal melanoma of upper site and NRAS mutation appear to be good predictors of response to immune checkpoint inhibitor and anti-angiogenic combination treatment. Targeting SMAD2 and p38 MAPK pathways may further improve the outcome of mucosal melanoma. KEY POINTS: 3-year follow-up study confirmed the therapeutic efficacy of atezolizumab combined with bevacizumab Tumors in the upper site and NRAS mutations are more sensitive to treatment Inflammatory cell infiltration, angiogenic status, and activation of the SMAD2 and p38 MAPK pathways may be prognostic indicators.
