Kidney cancer epidemiology in a French Afro-descendant population: high prevalence of papillary renal cell carcinoma.
Article in World journal of urology, 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
purposeEthnic disparities in renal cell carcinoma (RCC) subtypes have been well documented in the United States (US), but no comparable data exist for Afro-descendant populations living within a European healthcare system. In the US, several studies have shown a significantly higher incidence of papillary renal cell carcinoma among populations of African descent. The aim of this study is to analyze the epidemiology of kidney cancer in a French Caribbean population, mainly of African descent.
methodsThis retrospective study included all patients who underwent total or partial nephrectomy, or renal biopsy at the University Hospital of Guadeloupe between January 2016 and October 2022. Data on clinical features, tumor characteristics, biology, histology and survival were collected. Statistical analyses were performed using StatView version 5.0 software.
resultsA total of 126 patients had been included between January 2016 and October 2022. The median age at diagnosis was 66.0 years [IQR: 57.2–71.8]. Overall, 70% of patients had arterial hypertension, 12% were on dialysis and 5.6% had a history of kidney transplantation. Clear cell renal cell carcinoma accounted for 43% of cases and Papillary renal cell carcinoma for 36% of cases.
conclusionThese findings highlight unique epidemiological patterns in a French Afro-descendant populations and emphasize the need for molecular and clinical research focused on papillary RCC. These findings suggest potential environmental and genetic influences in the development of PRCC.
