[PMID: 38852018 DOI: 10.1016/j.urolonc.2024.05.019] [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: 02/01/2024] [Revised: 05/13/2024] [Accepted: 05/20/2024] [Indexed: 06/10/2024]
Abstract
OBJECTIVE To evaluate the classification and prognostic effects of a 2 cm tumor size in patients with ureteral cancer (UC) undergoing segmental ureterectomy (SU). PATIENTS AND METHODS A total of 75 patients with UC who underwent SU in our hospital between April 2013 and April 2023 were included in this study. The study population was grouped based on tumor size, which was defined as the maximum diameter of the pathological specimens, resulting in 30 patients (40.0%) with tumor size <2 cm and 45 patients (60.0%) with tumor size ≥2 cm. The clinicopathological variables, perioperative parameters, and oncological outcomes were compared between the 2 groups. The endpoints were recurrence-free survival (RFS), and cancer-specific survival (CSS). RESULTS A tumor ≥2 cm was related to a higher positive rate of urine exfoliative cytology (P = 0.049) and fewer preoperative ureteroscopies (P = 0.033) than tumors <2 cm. After a follow-up of 6.3 to 128.7 months (median 40.2 months), 23 cases (30.7%) experienced recurrence and 11 patients (14.7%) succumbed to UC in the end. Compared to those with tumor size <2 cm, patients with tumor size ≥2 cm experienced more urothelial recurrence (P = 0.032). Kaplan-Meier analysis demonstrated that patients with tumor size ≥2 cm displayed inferior urothelial RFS than those with tumor size <2 cm (P = 0.026). Multivariate Cox analysis identified tumor size ≥2 cm, and pathological stage ≥T2 were significant prognostic factors of poor urothelial RFS (all P < 0.05). CONCLUSION Tumor size ≥2 cm was associated with a high rate of urothelial recurrence and served as an independent prognostic factor of adverse urothelial RFS in SU-treated patients with UC. Patients are advised to select surgical treatments for UC following the EAU guidelines.

Abstract
OBJECTIVE To investigate clinicopathological characteristics, surgical treatments, and oncological outcomes of patients with localized primary unifocal urothelial carcinoma involving the ureterovesical junction (UC-UVJ). PATIENTS AND METHODS Localized primary unifocal UC-UVJ cases in patients admitted to our hospital from March 2013 to August 2021 were reviewed. Clinicopathological parameters, perioperative data, and oncological outcomes were compared between patients grouped by tumor location and surgical treatment. RESULTS A total of 130 patients with localized primary unifocal UC-UVJ were enrolled in this study. These included 72 cases of bladder cancer (BC) involving the ureteral orifice, and 58 cases of upper urinary tract urothelial carcinoma (UTUC) involving the intramural ureter. The proportion of male patients, hydronephrosis, flank pain/abdominal pain, and tumor size differed significantly between the BC and UTUC groups (all P < 0.05). During the median follow-up period of 32.9 months, 49 cases (37.7%) recurred and 29 (22.3%) died from urothelial carcinoma (UC), though no statistical difference in recurrence (P = 0.436) or cancer-specific mortality (P = 0.653) was observed between the BC and UTUC groups. Cox proportional hazards regression analysis identified age, tumor grade, and lymphovascular invasion (LVI) as independent predictors of cancer-specific survival (CSS), and sex, T stage, tumor grade, and LVI as independent predictors of recurrence-free survival (RFS). CONCLUSION Owing to positional properties, patients with localized primary unifocal UC-UVJ exhibited significant heterogeneity, leading to varied treatment strategies. No statistically significant differences in CSS or RFS were observed between the BC and UTUC groups. Furthermore, age, sex, T stage, tumor grade, and LVI should be carefully considered in clinical practice because of their associations with CSS and RFS.

Oncologic outcomes of patients treated with kidney-sparing surgery or radical nephroureterectomy for upper urinary tract urothelial cancer: a population-based study. Urol Oncol 2024; 42:22.e1-22.e11. [PMID: 37981503 DOI: 10.1016/j.urolonc.2023.09.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 09/17/2023] [Accepted: 09/26/2023] [Indexed: 11/21/2023]
Abstract
PURPOSE Although kidney-sparing surgery (KSS) is a nonminor option for low-risk upper urinary tract urothelial cancer (UTUC), its oncological benefits in high-risk UTUC remain unclear when compared to radical nephroureterectomy (RNU). This study aimed to compare the oncological outcomes of RNU and KSS in patients with UTUC. METHODS We searched the SEER database for patients treated for primary non-metastatic UTUC with either RNU or a kidney-sparing approach (segmental ureterectomy (SU) or local tumor excision (LTE)) between 2004 and 2018. RESULTS The study included 6,659 patients with primary non-metastatic UTUC treated with surgery; 2,888 (43.4%) and 3,771 (56.6%) patients presented with ureteral and renal pelvicalyceal tumors, respectively. Finally, 5,479 (82.3%) patients underwent RNU, 799 (12.0%) were treated with SU, and 381 (5.7%) patients received LTE. For confounder control, propensity score matching (PSM) of patients treated with SU and RNU was performed to adjust for T stage, grade, age, gender, tumor size, and lymphadenectomy performance. PSM analysis included 694 patients treated with RNU and 694 individuals who underwent SU. In multivariable Cox regression and Kaplan-Meier analyses, we found no difference in either CSS or OS between RNU and SU, even in the subgroup of high-grade and/or muscle-invasive UTUC including pT3-T4 tumors (all p > 0.05). CONCLUSION In this population-based study, SU provides equivalent CSS and OS compared to RNU, even in high-risk and locally advanced ureteral cancer. Due to the unavoidable risk of selection bias, further prospective studies are expected to overcome the limitations of this study and support the wider implementation of KSS.

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.

The impact of routine frozen section analysis during nephroureterectomy or segmental ureterectomy for urothelial carcinoma on final surgical margin status and long-term oncologic outcome. Urol Oncol 2023:S1078-1439(23)00130-8.

Abstract
OBJECTIVE The utility of intraoperative frozen section analysis (FSA) at the surgical margins (SMs) in patients with upper urinary tract cancer has not been established. We herein assessed the clinical significance of routine FSA of ureteral SMs during nephroureterectomy (NU) or segmental ureterectomy (SU). MATERIALS AND METHODS A retrospective review of our Surgical Pathology database identified consecutive patients undergoing NU (n=246) or SU (n=42) for urothelial carcinoma from 2004 to 2018. FSA (n=54) was correlated with the diagnosis of frozen section controls, the status of final SMs, and the prognosis of patients. RESULTS During NU, FSA was performed in 19 (7.7%) patients and was significantly more often requested in cases with ureteral tumor (13.1%) than in those with renal pelvis/calyx tumor (3.5%). Final SMs at the distal ureter/bladder cuff were positive only in non-FSA cases in the entire NU cohort (8.4%; P=0.375) or those with tumor at the lower ureter (57.6%; P=0.046), but not in any of FSA patients (0%). During SU, FSA was performed in 35 (83.3%) cases, including 19 at either proximal or distal SM and 16 at both SMs (SU-FSA2). Final positive SMs were significantly more often detected in non-FSA patients (42.9%) than in all FSA (8.6%; P=0.048) or SU-FSA2 (0%; P=0.020) patients. Overall, FSAs were reported as positive or high-grade carcinoma (n=7), atypical or dysplasia (n=13), and negative (n=34), and all these diagnoses were confirmed accurate on the frozen section controls, except one with a revision from atypical to carcinoma in situ. Meanwhile, 16 (80.0%) of 20 cases with initial positive/atypical FSA achieved negative conversion by excision of additional tissue. Kaplan-Meier analysis revealed that SU-FSA did not significantly reduce the risk of tumor recurrence in the bladder, disease progression, or cancer-specific mortality. Nonetheless, NU-FSA was strongly associated with reduced progression-free (P=0.023) and cancer-specific (P=0.007) survival rates, compared with non-FSA, which may imply a selection bias (e.g., FSA for clinically more aggressive tumors). CONCLUSIONS Performing FSA during NU for lower ureteral tumor, as well as during SU, significantly reduced the risk of positive SMs. However, routine FSA for upper urinary tract cancer failed to considerably improve long-term oncologic outcome.

Abstract
Introduction: Radical nephroureterectomy with bladder cuff excision (BCE) is the standard of care all high-risk upper tract urothelial carcinomas. With continued advancements, robot-assisted segmental ureteral resection can be employed for ureteral tumors for ipsilateral renal preservation. Herein, we are presenting our experience of different techniques classified by the affected ureteral segment, along with perioperative and intermediate to long-term functional and oncologic outcomes. Methods: From January 2008 to June 2021, a total of 17 patients underwent robot-assisted renal preserving excisional procedures for ureteral tumors. We collected and analyzed baseline, perioperative and follow-up outcomes parameters from our prospectively maintained institutional database. Eleven patients underwent segmental ureterectomy (SU) with BCE and ureteroneocystostomy with psoas hitch, five patients underwent SU with ureteroureteral anastomosis with/without psoas hitch, and one patient underwent ileal patch interposition after segmental ureteral excision. Results: Although majority of the patients had inconclusive or low-grade pathology on initial ureteroscopic biopsies, 73.33% of the patients were found to have high-grade tumors on final pathology report. Median tumor size was 2.7 cm (1-5.5 cm), and the median operative duration was 193 minutes (142-400 minutes). None of the procedures required conversion to open. Overall, only one patient (5.9%) had Clavien-Dindo grade ≥ III complication (pelvic abscess). At median follow-up of 41 months (7-156 months), four patients (26.67%) developed urothelial recurrences out of which only one patient required nephroureterectomy. Overall survival and nephroureterectomy-free survival were 86.67% and 92.31%, respectively. Conclusions: Our study provides a comprehensive review of various surgical approaches of robot-assisted renal sparing management for ureteral tumors. These procedures are surgically safe, feasible, and effective with satisfactory oncologic outcomes at intermediate to long-term follow-up. These procedures may be safely employed in select patients with a localized ureteral tumor to salvage the ipsilateral kidney and estimated glomerular filtration rate.

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.
