Adjuvant Systemic Therapies After Nephrectomy for Renal Cell Carcinoma: A Bayesian Network Meta-Analysis and Multi-Criteria Benefit-Risk Assessment.
Synthesis in Targeted oncology, 2026. 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
backgroundAdjuvant pembrolizumab has improved disease-free survival after nephrectomy for high-risk renal cell carcinoma, and pembrolizumab plus belzutifan has further expanded the treatment landscape.
objectiveWe compared efficacy and treatment burden across adjuvant systemic therapies and examined the benefit-risk trade-off of the combination.
methodsRandomized trials of systemic therapy after nephrectomy were synthesized using a Bayesian network meta-analysis. Disease-free survival hazard ratios were converted to illustrative 2-year estimates using a common pembrolizumab baseline. Observed differences in 2-year disease-free survival, grade 3 or higher adverse events, and treatment discontinuation came from LITESPARK-022. Using these data, a multi-criteria decision analysis examined how outcome weighting affected the balance between the two regimens.
resultsSix randomized datasets formed a tree-shaped network of eight regimens. In LITESPARK-022, adding belzutifan yielded approximately seven additional disease-free patients per 100 treated, but also approximately 22 additional patients with grade 3 or higher adverse events and 15 additional treatment discontinuations. Under the primary decision-analytic assumptions, the combination had the higher net-benefit score only when disease-free survival received roughly two thirds of the decision weight (threshold 0.68; range 0.47-0.79 across sensitivity analyses). Most comparisons relied on a single dataset, and overall survival and patient-reported outcomes remained immature.
conclusionsAdding belzutifan to pembrolizumab improved disease-free survival but increased toxicity and treatment discontinuation. The decision analysis illustrates a model-dependent trade-off rather than identifying a preferred regimen. Because overall survival data are immature, the decision to intensify treatment remains risk and preference sensitive. PROSPERO REGISTRATION: CRD420261454205.
