Long-term oncologic outcomes of metastatic clear-cell renal cell carcinoma after local therapy alone.
Article in Urologic 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
purposeOligometastatic clear-cell renal cell carcinoma (ccRCC) represents a heterogeneous entity that can, in select cases, be managed with primary tumor resection and complete local treatment at all metastatic sites, rendering a patient metastatic with no evidence of disease (M1 NED). M1 NED patients have improved overall survival, although previous cohorts are relatively small and heterogeneous. We sought to identify the natural history of M1 NED ccRCC to clinical trial findings and to optimize management strategies. MATERIALS AND
methodsPatients with synchronous metastatic ccRCC treated with local therapy alone and considered radiographically M1 NED at our institution between 1989 and 2023 were retrospectively evaluated. Survival probabilities used a combination of Kaplan-Meier estimator, log-rank test, and multivariable Cox proportional hazards regression. When available, limited genomic data obtained using the MSK-IMPACT targeted panel was correlated with outcomes.
results85 patients met inclusion criteria. One-year disease free survival (DFS) was 53% (95% CI: 42 to 63%). Sarcomatoid features predicted shorter DFS (HR 2.62, CI: 1.08, 6.34, P = 0.03). Time from first disease recurrence to second recurrence was longer among patients with initial DFS ≥2 years (median 42 vs. 15 months, log-rank P = 0.005). A total of 18 patients (21%) underwent targeted genomic sequencing; higher fraction of genome altered and CDKN2A copy number loss were associated with shorter DFS. Findings were limited by cohort size.
conclusionsMost M1 NED ccRCC patients will experience disease recurrence, although certain baseline risk factors appear to predict earlier recurrence. Prognostic biomarkers are needed to predict outcomes and facilitate patient management.
