Prevalence and oncologic impact of chronic kidney disease for upper tract urothelial carcinoma in endemic area. J Formos Med Assoc 2024; 123:758-763. [PMID: 38044211 DOI: 10.1016/j.jfma.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 11/14/2023] [Accepted: 11/21/2023] [Indexed: 12/05/2023] Open
Abstract
OBJECTIVE This study aimed to assess the impact of preoperative chronic kidney disease (CKD) on the oncological outcomes of patients with upper tract urothelial carcinoma (UTUC) who underwent standard radical nephroureterectomy (RNU). METHODS A total of 1172 UTUC patients who received RNU at a single center in Taiwan between February 2005 and August 2019 were included. The patients were categorized into two groups based on their preoperative CKD stage: CKD stage ≤3 (811 patients) and CKD stage >3 (361 patients). The estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) formula. The study investigated the oncological outcomes, including intravesical recurrence, non-urothelial recurrence, and cancer-specific mortality, stratified by preoperative CKD status. RESULTS The main findings indicated that UTUC patients with CKD stage >3 in Taiwan exhibited a higher proportion of females (p < 0.001), a greater history of concurrent bladder cancer (p = 0.003), more multifocal tumor behavior (p < 0.001), a higher incidence of carcinoma in situ (p = 0.008), increased rates of intravesical recurrence (p < 0.001), a lower prevalence of smoking history (p = 0.003), lower utilization of adjuvant chemotherapy (p < 0.001), reduced occurrence of non-urothelial recurrence (p < 0.001), and lower cancer-specific mortality (p = 0.006) compared to patients with CKD stage ≤3. Multivariate Cox regression analysis revealed significant differences in intravesical recurrence (p = 0.014) and non-urothelial recurrence (p = 0.006) between the CKD stage >3 and CKD stage ≤3 groups. The study also demonstrated that patients with concurrent bladder cancer and variant histology had higher rates of intravesical recurrence, non-urothelial recurrence, and cancer-specific mortality. The CKD stage >3 group exhibited lower rates of intravesical recurrence (p = 0.0014), higher rates of non-urothelial recurrence (p < 0.0001), and increased cancer-specific mortality (p = 0.0091) compared to the CKD stage ≤3 group in the 5-year free survival analysis. CONCLUSION In Taiwan, UTUC patients with CKD stage >3 exhibit distinct characteristics compared to the general population with urothelial carcinoma. They are associated with a non-smoking status, a higher proportion of females, and less aggressive pathological features. Additionally, CKD stage >3 can serve as a clinical indicator for intravesical and non-urothelial recurrence. Further investigation into molecular aspects and treatment modifications for these patients is warranted.

Perioperative renal function change and oncological outcomes of radical nephroureterectomy in patients with upper tract urothelial carcinoma: A multicenter retrospective study. Urol Oncol 2024:S1078-1439(24)00421-6. [PMID: 38729868 DOI: 10.1016/j.urolonc.2024.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 01/29/2024] [Accepted: 04/01/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND The effect of radical nephroureterectomy (RNUx) on postoperative renal function in patients diagnosed with upper tract urothelial carcinoma (UTUC) has not been thoroughly explored. METHODS We conducted a retrospective analysis including 785 patients who underwent RNUx for UTUC. We assessed the preoperative and postoperative estimated glomerular filtration rates (eGFRs) and factors related to the decline in eGFR. Additionally, we examined the effect of comorbidities (diabetes or hypertension) on the postoperative eGFR at 1 year. Cox proportional hazard models were employed to investigate the clinical effect of RNUx on oncological outcomes, including non-urothelial tract recurrence-free survival (NUTRFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS The median preoperative and postoperative eGFR levels were 54.7 and 40.6 ml/min/1.73 m2 respectively. The proportions of patients with preoperative and postoperative eGFR ≥60 mL/min/1.73 m2 were 35.9% and 5.1%, respectively. The median decline in the eGFR after surgery was 26.8%. Patients with preoperative eGFR <60 ml/min/1.73 m2 demonstrated significantly lower odds of a postoperative decline in eGFR of 25% or more. The effect of comorbidities on postoperative eGFR at 1 year was significant (P = 0.048). The 3-year NUTRFS, CSS, and OS rates were 72.9%, 85.2%, and 81.5%, respectively. Preoperative chronic kidney disease was an independent factor associated with inferior NUTRFS, CSS, and OS. CONCLUSION Different degrees of impairment of renal function occur among UTUC patients. Only 5.1% of patients retain a postoperative eGFR ≥60 ml/min/1.73 m2. Preoperative renal impairment was linked to reduced odds of postoperative eGFR decrease and associated with survival. In addition, the presence of comorbidities had a significant effect on the decline in eGFR. These findings emphasize the importance of developing evidence-based perioperative treatment strategies for UTUC patients with impaired renal function.

Oncologic outcomes following radical nephroureterectomy for upper tract urothelial carcinoma: a literature review. Transl Androl Urol 2023; 12:1351-1362. [PMID: 37680219 PMCID: PMC10481200 DOI: 10.21037/tau-22-882] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 07/10/2023] [Indexed: 09/09/2023] Open
Abstract
Background and Objective Radical nephroureterectomy (RNU) represents the gold standard treatment for non-metastatic upper tract urothelial cancer. We sought to provide a comprehensive review of reported oncologic outcomes of the RNU procedure and of factors that might impact these outcomes. Methods A non-systematic review of the literature was conducted by performing an electronic literature search using PubMed with "radical nephroureterectomy" and "oncologic outcomes" as free text search terms. Both original articles and systematic reviews were considered. Search was limited to articles in English that were published in the last 20 years. Key Content and Findings Open and laparoscopic RNU offer comparable oncologic outcomes. In more recent years, the discussion has de facto shifted towards the "oncological safety" of robotic RNU, which also seems to offer comparable oncologic outcomes. Several studies have looked at the impact of different treatment-, patient- and tumor-related factors. Among treatment-related factors, attention has been given to diagnostic ureteroscopy and the risk of intravesical recurrence. Surgical wait time and perioperative blood transfusion have also been studied. Perioperative chemotherapy, specifically adjuvant therapy, was shown to improve survival. Among patient-related factors, baseline chronic kidney disease, diabetes mellitus, body mass index, and systemic inflammation have gained recent attention. Some tumor related factors, such as stage, grade, location, and multifocality may negatively impact survival outcomes. Lymphovascular invasion and histologic variants are clinically significant pathological findings. Conclusions RNU is a procedure with measured long-term oncologic outcomes. Minimally invasive techniques have gained an established role as they seem to offer comparable oncologic "safety", although special attention is needed in relation to the method of bladder cuff excision. Robotic RNU is gaining popularity, and while evidence remains limited, the current literature supports the oncologic safety of this procedure. Several factors, which can be categorized as treatment-related, patient-related, and tumor-related, might impact the oncologic outcomes of UTUC patients undergoing RNU. These factors can provide crucial information to stratify patients based on their relative risk of disease recurrence and mortality which may guide clinical decision-making.
