Abstract Background Despite randomized data demonstrating better overall survival favoring radical nephrectomy, partial nephrectomy continues to be the treatment of choice for low-stage renal cell carcinoma. Methods We utilized the National Cancer Database to identify patients younger than 50 years diagnosed with low-stage renal cell carcinoma (cT1) treated with radical nephrectomy or partial nephrectomy (2004–2007). Inverse probability of treatment weighting adjustment was performed for all preoperative factors to account for confounding factors. Kaplan-Meier curves and Cox proportional hazards regression analyses were used to compare overall survival of patients in the two treatment arms. Sensitivity analysis was performed to explore the interaction of type of surgery and clinical stage on overall survival. Results Among the 3009 patients (median age = 44 years [interquartile range (IQR) = 40–47 years]), 2454 patients (81.6%) were treated with radical nephrectomy and 555 patients (18.4%) with partial nephrectomy. The median follow-up was 108.6 months (IQR = 80.2–124.3 months) during which 297 patients (12.1%) in the radical nephrectomy arm and 58 patients (10.5%) in the partial nephrectomy arm died. Following inverse probability of treatment weighting adjustment, there was no difference in overall survival between patients treated with partial nephrectomy and radical nephrectomy (hazard ratio = 0.83, 95% confidence interval = 0.63 to 1.10, P = .196). There were no statistically significant interactions between type of surgery and clinical stage on treatment outcome. Conclusions There was no difference in long-term overall survival between radical and partial nephrectomy in young and healthy patients. This patient cohort may have sufficient renal reserve over their lifetime, and preserving nephrons by partial nephrectomy may be unnecessary.

Background: Whether or not a survival difference exists between radical and partial nephrectomy for stage T1 renal cell carcinoma (RCC) is controversial. We therefore aimed to evaluate cancer-specific, other cause, and overall survival among patients undergoing radical or partial nephrectomy for stage pT1 RCC. Materials and methods: We identified 330 participants with pT1a-b RCC diagnosed between 2000-2015 in three prospective cohort studies and compared treatment with radical nephrectomy (N=196) versus partial nephrectomy (N=134). The primary outcome was overall survival. Secondary outcomes were other-cause and cancer-specific mortality. Kaplan-Meier plots were used to visualize overall survival for the two treatment groups. Cox proportional hazards regression was utilized to compare outcomes between groups, and Fine and Gray competing risks regression was used to compare cancer-specific and other cause mortality between groups. Multivariable models adjusted for age, tumor size, sex, year of diagnosis, body mass index, history of smoking, history of hypertension, surgical technique, and pathological differentiation. Results: During a median follow-up of eight years, overall survival was 84%. We did not detect a statistically significant difference in overall survival between partial and radical nephrectomy (Hazard Ratio (HR) = 0.84, 95% Confidence Interval: 0.40-1.78). There was no significant difference in cause-specific or other cause mortality between groups. This study had 80% power to detect an HR ≥2.20. Conclusions: These results did not suggest a difference in long-term survival outcomes between radical and partial nephrectomy.

AbstractThe aim of this work is to investigate the applicability of radiomic features alone and in combination with clinical information for the prediction of renal cell carcinoma (RCC) patients’ overall survival after partial or radical nephrectomy. Clinical studies of 210 RCC patients from The Cancer Imaging Archive (TCIA) who underwent either partial or radical nephrectomy were included in this study. Regions of interest (ROIs) were manually defined on CT images. A total of 225 radiomic features were extracted and analyzed along with the 59 clinical features. An elastic net penalized Cox regression was used for feature selection. Accelerated failure time (AFT) with the shared frailty model was used to determine the effects of the selected features on the overall survival time. Eleven radiomic and twelve clinical features were selected based on their non-zero coefficients. Tumor grade, tumor malignancy, and pathology t-stage were the most significant predictors of overall survival (OS) among the clinical features (p < 0.002, < 0.02, and < 0.018, respectively). The most significant predictors of OS among the selected radiomic features were flatness, area density, and median (p < 0.02, < 0.02, and < 0.05, respectively). Along with important clinical features, such as tumor heterogeneity and tumor grade, imaging biomarkers such as tumor flatness, area density, and median are significantly correlated with OS of RCC patients.
