Background And Objective: Our aim was to determine the clinical characteristics, temporal trends, and survival outcomes for sarcomatoid-dedifferentiated renal cell carcinoma (sRCC), as sRCC has historically had poor prognosis and a contemporary cohort has not been well characterized in a population-based study.
Methods: Data for 302 630 RCC cases from 2010 to 2019 were extracted from the National Cancer Data Base, of which 4.1% (12 329) were sRCC.
Background: C-reactive protein (CRP) is a prognostic biomarker for clear cell renal cell carcinoma (ccRCC). However, there may be potential racial heterogeneity in distribution and prognostic impact of CRP level. We investigated potential racial differences in distribution and prognostic impact of preoperative CRP among Asian (AS), African American (AA), and Caucasian (CAUC) patients with non-metastatic ccRCC (nmccRCC).

- This study aimed to analyze how common surgically induced chronic kidney disease (CKD-S) is in patients with upper tract urothelial carcinoma (UTUC) after they undergo radical nephroureterectomy (RNU), focusing on survival outcomes.* -
- Researchers looked at data from 1,862 patients and found that 34.7% developed CKD-S3a and 39.6% developed CKD-S3b after surgery, with older age, lower preoperative kidney function, and certain chemotherapy treatments linked to higher risks of developing CKD-S3b.* -
- The study revealed that while CKD-S3b patients had worse overall survival rates (59% over 5 years), CK
Article Synopsis
- - The study aimed to create a preoperative tool called NODESAFE to predict nodal involvement (NI) in patients with localized renal cell carcinoma (RCC) before surgery, addressing the ongoing debate about the need for lymphadenectomy.
- - Researchers conducted a multicenter analysis of 3,308 RCC patients who had primary surgical resections, excluding those with clinical metastasis, using a stepwise logistic regression model to identify significant predictive factors for NI, achieving an AUC of 0.89 in validation.
- - The final NODESAFE model included factors like hypertension, tumor size, and CRP levels, demonstrating high sensitivity (83.9%) and specificity (86.1%), which could enhance clinical decision-making
Article Synopsis
- This study examines how the Mayo Adhesive Probability (MAP) score and body mass index (BMI) affect kidney function decline after patients undergo robotic assisted partial nephrectomy (RAPN).
- A total of 258 patients were analyzed over a median follow-up of 33 months, revealing that a higher MAP score and increased BMI are correlated with a greater risk of developing chronic kidney disease stage 3 (CKD-S3).
- The findings suggest that higher MAP scores and obesity can negatively impact long-term kidney function, indicating a need for careful monitoring before surgery in at-risk patients.
Article Synopsis
- In a study of 4011 patients who had unilateral cT1a-b renal mass treated with partial nephrectomy, researchers aimed to explore how a surgeon's experience affects surgical outcomes, specifically acute kidney injury (AKI) and kidney function a year post-surgery.
- Previously, it was known that complications and ischemia times improved with surgeon experience, but there was limited data on long-term kidney function.
- The findings revealed no significant association between surgical experience and AKI or recovery of kidney function in either laparoscopic or robot-assisted techniques, suggesting other factors may play a more crucial role in these outcomes.
Article Synopsis
- The study investigates the effects of neoadjuvant and adjuvant chemotherapy on survival rates in patients with Upper tract urothelial carcinoma undergoing Nephroureterectomy, using data from a multicenter registry.
- A total of 1,994 patients were analyzed, revealing that neoadjuvant chemotherapy notably improved cancer-specific and overall survival, especially in patients with advanced tumors or positive nodes.
- The results suggest a significant survival benefit from neoadjuvant chemotherapy, indicating a need for further research to explore its impact in this patient population.
Survival Outcomes by Race Following Surgical Treatment for Upper Tract Urothelial Carcinoma.
Clin Genitourin Cancer
December 2024
Objective: Discrepancies in survival outcomes of various genitourinary tract malignancies have been documented across different racial and ethnic groups. Here we sought to examine long-term survival outcomes of patients with upper tract urothelial carcinoma (UTUC) following radical nephroureterectomy (RNU) when stratified by race.
Methods: A multicenter retrospective analysis using the ROBUUST (ROBotic surgery for Upper tract Urothelial cancer Study) registry identified patients undergoing RNU for UTUC between 2015 and 2022 at 12 centers across the United States, Europe, and Asia.
Objective: To analyse surgical, functional, and mid-term oncological outcomes of robot-assisted nephroureterectomy (RANU) in a contemporary large multi-institutional setting.
Patients And Methods: Data were retrieved from the ROBotic surgery for Upper tract Urothelial cancer STtudy (ROBUUST) 2.0 database, an international, multicentre registry encompassing data of patients with upper urinary tract urothelial carcinoma undergoing curative surgery between 2015 and 2022.
Objective: To evaluate the role of pelvic lymph node dissection (PLND) in patients diagnosed with high-risk nonmuscle-invasive bladder cancer (NMIBC) undergoing radical cystectomy (RC) using a national cohort of NMIBC patients.
Methods: A cohort of patients diagnosed with NMIBC cancer with urothelial carcinoma from the National Cancer Database (NCDB) between 2004 and 2019 was utilized. The cohort consists of patients who have not received BCG and underwent upfront radical cystectomy or pelvic exenteration.
Article Synopsis
- This study compares outcomes of radical nephrectomy (RN) versus partial nephrectomy (PN) for treating sarcomatoid renal cell carcinoma (sRCC) using a large national database from 2004 to 2019.
- The analysis found that patients receiving PN had better overall survival rates, particularly in early-stage tumors (cT1 and cT3), although factors like age and tumor characteristics influenced the likelihood of receiving PN.
- The results suggest that PN can be a viable option for certain patients without compromising outcomes, but disparities in care exist based on income and insurance status, affecting survival rates.
Objectives: We sought to determine whether bladder cuff excision and its technique influence outcomes after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).
Methods And Materials: A multicenter, international, retrospective analysis using the ROBotic surgery for Upper tract Urothelial cancer Study (ROBUUST) 2.0 registry identified 1,718 patients undergoing RNU for UTUC between 2015 and 2023 at 17 centers across the United States, Europe, and Asia.
Objective: To evaluate predictive ability of a novel combined index, Charlson comorbidity index and C-reactive protein (CCI-CRP), for outcomes in renal cell carcinoma (RCC), and compare predictive outcomes with of CCI-CRP to its separate components and to the UCLA integrated staging system (UISS).
Patients And Methods: We retrospectively analyzed INMARC registry of RCC patients. Receiver Operator Characteristics (ROC) analysis was fitted to identify threshold defining low-CRP (LCRP) and high-CRP (HCRP).
Objective: Stage migration in renal cell carcinoma (RCC) has led to an increasing proportion of diagnosed small renal masses. Emerging knowledge regarding heterogeneity of RCC histologies and consequent impact on prognosis led us to further explore outcomes and predictive factors in surgically-treated T1a RCC.
Methods: The INMARC database was queried for T1aN0M0 RCC.
Background: The role of kidney-sparing surgery in patients with high-risk upper urinary tract urothelial carcinoma is controversial. The present study aimed to assess oncological and functional outcomes of robot-assisted distal ureterectomy in patients with high-risk distal ureteral tumors.
Methods: The ROBUUST 2.
Article Synopsis
- Deterioration of kidney function can lead to higher mortality rates, and it's unclear how different surgical options (partial nephrectomy [PN] vs. radical nephrectomy [RN]) for large renal masses impact long-term kidney health.
- A study analyzing data from 23 institutions showed that patients undergoing PN experienced significantly lower rates of acute kidney injury (AKI) and better recovery of kidney function at one year compared to those undergoing RN.
- The findings suggest that avoiding RN, when possible, is beneficial for preserving kidney function and reducing the risk of serious complications related to kidney health after surgery.
Purpose: Given the emergence of PSMA-targeted diagnostic agents and therapeutics, we sought to investigate patterns of expression in RCC and their impacts on RCC outcomes.
Methods: We conducted a pooled multi-institutional analysis of patients with RCC having undergone DNA and RNA next-generation sequencing. -high/low expression was defined as the ≥75th/<25th percentile of RNA transcripts per million (TPM).
Background: Diagnostic ureteroscopy (URS) with or without biopsy remains a subject of contention in the management of upper tract urothelial carcinoma (UTUC), with varying recommendations across different guidelines. The study aims to analyse the decision-making and prognostic role of diagnostic ureteroscopy (URS) in high-risk UTUC patients undergoing curative surgery.
Materials And Methods: In this retrospective multi-institutional analysis of high-risk UTUC patients from the ROBUUST dataset, a comparison between patients who received or not preoperative URS and biopsy before curative surgery was carried out.
Background: To evaluate relationship between histological subtypes of renal cell carcinoma (RCC) and preoperative c-reactive protein (CRP).
Patients And Methods: We queried the International Marker Consortium for Renal Cancer database for patients affected by RCC. Patients were classified according to their histology: benign tumors, clear cell (cc) RCC, chromophobe (ch) RCC, papillary (p) RCC, and variant histology (vh) RCC; and according to CRP (mg/L): low CRP ≤5 and high CRP >5.
Background And Objective: The role of cytoreductive nephrectomy (CN) in the treatment of metastatic renal cell carcinoma (mRCC) has been called into question on the basis of clinical trial data from the tyrosine kinase inhibitor (TKI) era. Comparative analyses of CN for patients treated with immuno-oncology (IO) versus TKI agents are sparse. Our objective was to compare CN timing and outcomes among patients who received TKI versus IO therapy.
