Postoperative mortality in renal cell carcinoma with vena cava thrombus in the elderly population (uroCCR study n°192).

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
objectiveInferior vena cava (IVC) thrombus is a severe presentation of renal cell carcinoma (RCC), traditionally treated by radical nephrectomy and thrombus extraction. However, the risk-benefit balance in elderly patients remains unclear due to limited data. This study aimed to assess surgical outcomes-particularly 90-day mortality-in patients aged ≥ 70 year and to identify risk factors for postoperative mortality.
methodsWe retrospectively analyzed data from the prospective French UroCCR national cohort (2007-2023), including 298 patients with RCC with IVC thrombus who underwent surgery in 13 expert centers. Patients were stratified into ≥ 70 vs. <70 year. The primary endpoint was 90-day mortality. Secondary outcomes included overall survival (OS), disease-specific survival (DSS), and predictors of 90-day postoperative mortality. Statistical analyses included univariate and multivariate logistic regression analyses adjusted for renal dysfunction.
resultsPatients aged ≥ 70 year (n = 117) had a 90-day mortality rate of 10.5% compared with 5.5% in those < 70 year (n = 181; p = 0.13). Among patients aged ≥ 80 year (n = 32), the 90-day mortality increased to 19% (p = 0.02). Metastatic disease (OR 3.3, p = 0.01) and preoperative renal dysfunction (OR 3.9, p = 0.02) were significantly associated with 90-day mortality, with renal dysfunction remaining independently associated after adjustment for age (adjusted OR 2.8, p = 0.04). Long-term DSS did not differ between age groups. Study limitations include its retrospective design and the restriction of the cohort to surgical candidates treated in expert centers.
conclusionsRadical nephrectomy with thrombectomy provides acceptable outcomes in patients aged ≥ 70 year, although ≥ 80 year face higher perioperative risk. Careful patient selection, including thorough preoperative renal function assessment, is crucial. The comparable DSS suggests that age alone should not be considered a contraindication to surgery.
