Same Organ, Two Cancers: Complete Analysis of Renal Cell Carcinomas and Upper Tract Urothelial Carcinomas. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1126. [PMID: 39064555 PMCID: PMC11279004 DOI: 10.3390/medicina60071126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2024] [Revised: 07/06/2024] [Accepted: 07/10/2024] [Indexed: 07/28/2024]
Abstract
Background and Objectives: Renal cell carcinomas and upper tract urothelial carcinomas are types of malignancies that originate in the kidneys. Each of these examples shows an increasing trend in the frequency and the mortality rate. This study aims to comprehensively define carcinomas by analyzing clinical, paraclinical, and histological aspects to predict aggressiveness and mortality. Materials and Methods: We conducted a retrospective investigation on a group of patients suspected of kidney cancers. Results: We identified 188 cases. We observed a higher mortality rate and older age in individuals with urothelial carcinomas. Anemia, acute kidney injury, hematuria, and perineural invasion were the main risk factors that predicted their mortality. Tumor size in renal cell carcinomas correlates with the presence of necrosis and sarcomatoid areas. Factors that indicate a higher rate of death are older age, exceeding the renal capsule, a lesion that includes the entire kidney, lymphovascular invasion, acute kidney injury, and anemia. Conclusions: Even if they originate at the renal level, and the clinical-paraclinical picture is similar, the histopathological characteristics make the difference. In addition, to these are added the previously mentioned common parameters that can represent important prognostic factors. In conclusion, the characteristics commonly identified in one type of cancer may act as risk factors for the other tumor. The detected data include threshold values and risk factors, making a significant contribution to the existing literature.

Abstract
CONTEXT Lymphadenectomy during surgery for genitourinary malignancies has varying benefits. OBJECTIVE To review contemporary evidence on lymph node dissection in genitourinary cancers. EVIDENCE ACQUISITION We performed a collaborative review to summarize current evidence supporting lymph node dissection in urothelial, prostate, kidney, penile, and testis cancers. We present the evidence on patient selection and recommended dissection templates, and highlight knowledge gaps and ongoing areas of investigation. EVIDENCE SYNTHESIS Lymph node dissection remains the reference standard for lymph node staging. Pathologic nodal stage informs prognosis and guides adjuvant treatment. Appropriate template and patient selection are paramount to optimize outcomes and capitalize on the selective therapeutic benefits. CONCLUSIONS Accurate staging with lymphadenectomy is contingent on appropriate template selection. The cumulative benefit will depend on judicious patient selection. PATIENT SUMMARY We performed a collaborative review by a diverse group of experts in urology. We reviewed current evidence on lymph node dissection.

Abstract
PURPOSE OF REVIEW This narrative review aims to evaluate the role of lymph node dissection (LND) in upper tract urothelial carcinoma (UTUC) and its implications for staging and management outcomes, as well as future perspectives. RECENT FINDINGS Multiple studies have demonstrated the limitations of conventional imaging techniques in accurately localizing lymph node metastasis (LNM) in UTUC. While 18F-fluorodeoxyglucose positron emission tomography with computed tomography (18FDG-PET/CT) shows promise for preoperative LNM detection, its specificity is low. Alternative methods such as choline PET/CT and sentinel lymph node detection are under consideration but require further investigation. Additionally, various preoperative factors associated with LNM hold potential for predicting nodal involvement, thereby improving nodal staging and oncologic outcomes of LND. Several surgical approaches, including segmental ureterectomy and robot-assisted nephroureterectomy, provide a possibility for LND, while minimizing morbidity. LND remains the primary nodal staging tool for UTUC, but its therapeutic benefit is still uncertain. Advances in imaging techniques and preoperative risk assessment show promise in improving LNM detection. Further research and multi-center studies are needed to comprehensively assess the advantages and limitations of LND in UTUC, as well as the long-term outcomes of alternative staging and treatment strategies.

UROLOGY RESEARCH & PRACTICE 2023; 49:345-359.

Abstract
This systematic review was performed to study the prognostic value of lymph node dissection (LND) during nephroureterectomy in upper tract urothelial cancer (UTUC). Five databases were searched on September 11, 2022, to include studies that compared whether LND was performed, the extent of dissection (complete vs. incomplete), and the nodal status (positive "pN+" vs. negative "pN0"). Outcomes included prognosis (overall survival "OS," cancer-specific survival "CSS," disease-free survival "DFS," and recurrence-free survival "RFS") and complications. High-grade complications (≥ grade 3 according to the Clavien-Dindo classification). Data analysis were conducted through STATA. The pooled data are reported log odds ratio (logOR) with 95% CI. Thirty-three studies were analyzed. The LND resulted in improved 5-year OS [logOR=0.10; 95% CI: 0.06-0.15], 5-year CSS [logOR=0.10; 95% CI: 0.04- 0.17], and 10-year CSS [logOR=0.14; 95% CI: 0.06-0.21] when compared to non-LND. However, LND was associated with greater risk of high-grade complications [logOR=0.62; 95% CI: 0.26-0.98]. Complete LND was associated with lower risk of cancer-specific mortality than incomplete LND [logOR=-0.69; 95% CI: -1.22--0.16]. The pN0 patients had better 5-year OS; however, pN+ patients had better prognosis in DFS, RFS (at 2 and 5 years), and CSS (at 2, 5, and 10 years). Lymph node dissection provides a protective role in terms of 5-year OS and 5-year and 10-year CSS among UTUC patients. However, it is associated with higher risk of high-grade complications. The extent of dissection plays a minor prognostic role, while the positivity of resected nodes has great prognostic value in UTUC.

Abstract
BACKGROUND For medical institutions without robotic equipment, it remains uncertain whether laparoscopic radical nephroureterectomy (LNU) can achieve results similar to those of robotic surgery for the treatment of upper tract urothelial carcinoma (UTUC). This meta-analysis aimed to compare the efficacy and safety of robot-assisted radical nephroureterectomy (RANU) with that of LNU using a large sample size of patients. METHODS A systematic meta-analysis was performed using data (available to May 2022) acquired from multiple scientific databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines, according to the protocols registered with PROSPERO (CRD42021264046), were followed to perform this cumulative analysis. RESULTS Nine high-quality studies were included in this analysis, considering factors such as operative time (OT), estimated blood loss (EBL), length of hospital stay (LOS), positive surgical margins (PSM), and complications. Statistical indicators revealed no significant differences between the RANU and LNU groups in terms of OT (weighted mean difference [WMD] 29.41, 95% confidence interval [CI] -1.10 to 59.92; p = 0.22), EBL (WMD -55.30, 95% CI -171.14 to 60.54; p = 0.13), LOS (WMD -0.39, 95% CI -1.03 to 0.25; p = 0.12), PSM (odds ratio [OR] 1.22, 95% CI 0.44-3.36; p = 0.17], or complications (OR 0.91, 95% CI 0.49-1.69; p = 0.13). CONCLUSION The meta-analysis showed that the perioperative and safety indicators of both RANU and LNU were similar and both showed favorable outcomes in UTUC treatment. However, some uncertainties remain in the implementation and selection of lymph nodes for dissection.

Abstract
Background Upper tract urothelial carcinoma (UTUC) is a rare and highly malignant urothelial tumor originating from the renal pelvis and ureter associated with poor prognosis. It has been established that 70% of ureteral tumors occur in the lower ureter. Radical nephroureterectomy (RNU) with ipsilateral bladder cuff excision is regarded as the standard treatment for UTUC. Current evidence supports the role of lymph node dissection (LND) in determining tumor staging, but no consensus has been reached on the potential survival benefits. The present study retrospectively analyzed cases of UTUC limited to the lower ureter to evaluate the survival benefits of LND during RNU. Methods The present study retrospectively analyzed data from patients with UTUC limited to the lower ureter from two medical centers from 2000 to 2016 and assessed the survival outcomes, including recurrence-free survival (RFS) and cancer specific survival (CSS). During subgroup analysis, we stratified by pathological tumor (pT) stages and postoperative adjuvant chemotherapy (AC). Results The study cohort included 297 patients separated into LND (n=111) and non-LND (n=186) groups. The two groups were comparable except for the pathological N stage. The LND group was associated with superior survival in terms of RFS (27.0% vs. 18.3%, p=0.044) and CSS (53.2 vs. 39.8%, p=0.031) compared to the non-LND group (n=186). In pT2-4 patients, the LND group was associated with better 3-year RFS (50.5% vs. 32.3%, p<0.05), 5-year RFS (29.7% vs. 12.0%, p<0.05), and overall RFS (18.7% vs. 6.0%, p<0.05) than the non-LND group. Besides, the LND group was associated with a significantly better 3-year CSS (68.1% vs. 49.6%, p=0.003), 5-year CSS (51.6% vs. 30.8%, p<0.05) and overall CSS (45.1% vs. 24.1%, p<0.05). In patients that underwent AC, the LND group had better survival benefits in terms of RFS (29.4 vs. 16.7%, p=0.023) and CSS (52.9% vs. 40.5%, p=0.038) compared to the non-LND group. Conclusion LND has survival benefits in patients with UTUC localized to the lower ureter, especially for≥pT2 stage UTUC and AC cohorts. Overall, the therapeutic effect of LND in UTUC cannot be replaced by AC.

Radical nephroureterectomy for UTUC conferred survival benefits irrespective of age and comorbidities. World J Urol 2022; 40:2657-2665. [PMID: 36125506 DOI: 10.1007/s00345-022-04152-7] [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: 04/06/2022] [Accepted: 09/07/2022] [Indexed: 10/14/2022] Open
Abstract
PURPOSE We investigated the effects of age, American Society of Anesthesiologists Physical Status Classification (ASA) grading and Charlson Comorbidity Index (CCI) on the survival outcomes of upper tract urothelial carcinoma (UTUC). METHODS The CROES-UTUC registry was an international, multicenter study on patients with UTUC. Primary outcomes were overall survival (OS) and disease-free survival (DFS). Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to their age (≤ 70 and > 70 years old) and ASA grade (I-II and III-V)/CCI (0-1 and ≥ 2). RESULTS A total of 2352 patients were included in this study. Patients aged ≤ 70 years with ASA grading of I-II (p = 0.002), and patients aged ≤ 70 years with a CCI of 0-1 (p = 0.002) had the best OS. Upon multivariate analysis, both in patients aged ≤ 70 and > 70 years, ASA grading and CCI were not significantly associated with OS. Patients aged ≤ 70 years with ASA grading of III-IV (p = 0.024) had the best DFS. When stratified according to age and CCI, no significant difference in DFS was noted. Upon multivariate analysis, radical nephroureterectomy (RNU) was significantly associated with better DFS in patients aged ≤ 70 and > 70 years; CCI of ≥ 3 was significantly associated with worse DFS in patients ≤ 70 years; ASA grading was not associated with DFS in patients aged ≤ 70 and > 70 years. CONCLUSIONS A high ASA grading and CCI should not be considered contraindications for RNU. RNU should be considered even in elderly patients when it is deemed feasible and achievable after a geriatric assessment.

Abstract
OBJECTIVES To describe the detailed perioperative complications and their management after retroperitoneal lymph node dissection with retroperitoneal laparoscopic radical nephroureterectomy for patients with upper tract urothelial carcinoma at three institutions. METHODS Retroperitoneal lymph node dissection was performed on patients with upper tract urothelial carcinoma located at the pelvis and/or upper or middle ureter, and its template included the renal hilar and para-aortic lymph nodes (left side) and the renal hilar, paracaval, retrocaval, and intra-aortocaval lymph nodes (right side). The lymph nodes and kidneys were removed en bloc. The primary endpoint was postoperative complication rates, and the secondary endpoints were intraoperative findings and chylous leakage management. The associations of retroperitoneal lymph node dissection with postoperative complications were examined using logistic regression with propensity score techniques. RESULTS Eighty-eight (31%) and 195 (69%) patients underwent and did not undergo retroperitoneal lymph node dissection, respectively. There was no significant difference in postoperative complications and other perioperative findings in the entire cohort, except for prolonged operation time. Retroperitoneal lymph node dissection was not statistically significantly associated with total and serious complications in propensity score analyses. Postoperative chylous leakage could be conservatively managed even though it is common in patients with retroperitoneal lymph node dissection (14/88 (16%)). The incidence of chylous leakage was significantly lower in patients whose lymphatic vessels were meticulously clipped completely during retroperitoneal lymph node dissection (5.3% vs 24%; P = 0.017). CONCLUSION There was no association between retroperitoneal lymph node dissection with laparoscopic radical nephroureterectomy and postoperative complications. However, chylous leakage is often observed after retroperitoneal lymph node dissection and careful management is highly required. The use of clips during retroperitoneal lymph node dissection is recommended to minimize chylous leakage risk.
