Clear cell and non-clear cell renal cell carcinoma in young adults: clinicopathological features, survival outcomes and prognostic factors.
Article in World journal of urology, 2024. 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
objectivesRenal cell carcinoma (RCC) is infrequent among young adults. Few studies reported the outcome of RCC in young adults by pathological subtypes. The purpose of this study was to explore the clinicopathological features, survival outcomes and prognostic factors of young adult patients with clear cell (CCRCC) and non-clear cell renal cell carcinoma (NCCRCC).
methodsThis study included young adult patients aged 18-40 years who were diagnosed as renal cell carcinoma (RCC) between 2012 and 2022 at Peking University Third Hospital. All patients underwent either partial nephrectomy or radical nephrectomy, and some received adjuvant therapy. A comparative analysis was performed to investigate the differences in clinicopathological characteristics between the cohort of CCRCC and NCCRCC. Kaplan-Meier survival analysis was utilized to plot survival curves for young adults with RCC. The univariate and multifactorial prognostic analyses were conducted using the log-rank test and COX proportional hazards model.
resultsA total of 300 RCC patients aged 18-40 years were performed, of which 201 were diagnosed with CCRCC (67%) and 99 were diagnosed with NCCRCC(33%). The NCCRCC included 29 cases (9.7%) of chromophobe RCC, 28 cases (9.3%) of MiT family translocation RCC, 22 cases (7.3%) of papillary RCC, 11 cases (3.7%) of low malignant potential multifocal cystic RCC, and 6 cases of unclassified RCC (2.0%), 2 cases of mucinous tubule and spindle cell carcinoma (0.7%), and 1 case of FH-deficient RCC (0.3%).The mean age was 33.4 ± 6.1 years old. The overall and progression free 5-year survival rate was 99.1 and 95.3%, respectively. The NCCRCC cohort demonstrated a statistically significant decrease in progression-free survival (PFS) rate when compared to the CCRCC cohort (p < 0.001). There was no statistically significant difference observed in overall survival (OS) (p = 0.069). Pathological stage was a significant independent predictor for OS (p = 0.045). Pathological stage and nuclear grade were both independent predictors for PFS (p = 0.020; p = 0.005).
conclusionsThe clinical and pathological features of young adults diagnosed with CCRCC exhibit notable distinctions from those of NCCRCC patients. The survival outcome was significantly influenced by the pathological stage, while both the nuclear grade and pathological stage had a significant impact on tumor progression. This study offered significant contributions to the understanding of the clinicopathological characteristics and prognostic determinants of renal cell carcinoma (RCC) in young adults.
