Real-world evidences on adjuvant Pembrolizumab for renal cell carcinoma: results from the multicenter real-world ARON-1 study.
Article in Cancer immunology, immunotherapy : CII, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPembrolizumab has demonstrated efficacy in improving disease-free survival (DFS) and overall survival (OS) as adjuvant therapy in clear cell renal cell carcinoma (ccRCC) at a higher risk of recurrence. However, real-world data on its effectiveness and safety remain limited. This study evaluates DFS, OS and severe adverse events (SAEs) associated with adjuvant pembrolizumab in a multicenter international cohort.
methodsThis retrospective analysis included 311 ccRCC patients treated with adjuvant pembrolizumab across 40 hospitals in 12 countries from the ARON-1 dataset. Eligible patients had histologically confirmed ccRCC with high relapse risk and received up to 17 cycles of pembrolizumab. The primary objective was DFS, with OS and safety as secondary objectives. Kaplan-Meier survival estimates, Cox proportional hazards models and log-rank tests were used for statistical analysis.
resultsAt a median follow-up of 15.4-month, 2-year OS and DFS rates were 95% and 69%, respectively. Recurrence occurred in 20% of patients, primarily in the lungs (11%) and bones (5%). DFS was significantly impaired in patients < 65 years (HR 2.14, p = 0.005), N1 disease (HR 5.42, p = 0.004) and sarcomatoid dedifferentiation (HR 2.54, p = 0.007). SAEs led to 19% treatment discontinuation, with colitis (4%), hypertransaminasemia (4%) and nephritis (3%) as the most common events. The study's retrospective nature and short follow-up limit long-term outcome assessments.
conclusionsThis large real-world study confirms pembrolizumab's effectiveness and manageable safety profile in the adjuvant setting for intermediate-high and high-risk ccRCC. Further research is needed to refine patient selection strategies and evaluate long-term outcomes.
