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.

Predictive Value of Flank Pain and Gross Hematuria on Long-Term Survival in Patients With Upper Tract Urothelial Carcinoma Treated by Radical Nephroureterectomy. CLINICAL MEDICINE INSIGHTS: ONCOLOGY 2023; 17:11795549221147993. [PMID: 36685988 PMCID: PMC9846590 DOI: 10.1177/11795549221147993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 12/12/2022] [Indexed: 01/19/2023] Open
Abstract
Background Assessing the prognosis preoperatively in patients with upper tract urothelial carcinoma (UTUC) remains a challenge for urologists. Gross hematuria (GH) and flank pain (FP) are the 2 most common and easily perceived symptoms of UTUC. Therefore, we aimed to investigate the prognostic values of GH and FP in patients with UTUC after undergoing radical nephroureterectomy (RNU). Methods This article retrospectively analyzed 179 patients with UTUC who underwent RNU and examined the associations between the FP, GH, and long-term survival. After dividing patients into 4 subgroups (presenting as GH without FP, FP without GH, no FP and GH, FP with GH), we focused on the prognostic values of the 4 subgroups using univariate and multivariate analyses. We then proposed a risk stratification model for UTUC based on the independent prognostic factors for cancer-specific survival (CSS) with external validation (146 additional UTUC patients formed the validation cohort). Results Patients with FP had worse oncological outcomes than those without FP (P < .05). After dividing the 179 patients into 4 subgroups, the "FP without GH" subgroup suffered the worst oncological outcomes (P < .001). The Cox multivariate regression analysis showed that "FP without GH" (P < .001), tumor multifocality (P = .005), and pathological stage (P = .004) were independent prognostic factors for CSS. Good performance of the risk stratification model was achieved in both the training and external validation cohorts. Conclusion The presence of "flank pain without gross hematuria" was one of the independent risk factors of CSS and OS besides the pathological stage and tumor multifocality. To our knowledge, this is the first study that adding complaint to risk stratification model in UTUC.

Abstract
OBJECTIVE The study objective was to investigate the prognostic risk factors related to overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and metastasis-free survival (MFS) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Patients were then divided into different risk groups (based on their number of prognostic risk factors), and specific postoperative treatment plans were formulated for patients in different risk groups. METHODS We retrospectively analyzed the data of 401 patients with UTUC who underwent RNU between 2010 and 2020. Univariate and multivariate Cox regression analyses were used to evaluate the associations of clinicopathological variables with prognosis among UTUC patients. Kaplan-Meier survival analysis of patients in different risk groups (based on their number of prognostic risk factors) was conducted. RESULTS Multivariate Cox regression analysis showed that sex (being male), LVI, pT stage (>pT2), and lack of postoperative intravesical instillation were independent risk predictors of shorter OS, CSS, RFS, and MFS (all P<0.05). Laparoscopic RNU was also associated with shorter OS, CSS, and MFS, but not with shorter RFS (P=0.068). After risk stratification, the 5-year OS, CSS, RFS, and MFS in the high-risk group were 42.3%, 46.4%, 41%, and 46%, respectively. CONCLUSIONS Sex (being male), LVI, pT stage (>pT2), and intravesical instillation were independent predictors of OS, CSS, RFS, and MFS for UTUC. All were risk factors, except for intravesical instillation, which was a protective factor. Additionally, laparoscopic RNU was an independent risk factor for OS, CSS, and MFS. Patients in the high-risk group may benefit greatly from adjuvant or neoadjuvant chemotherapy.

Factors Predicting Oncological Outcomes of Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma in Taiwan. Front Oncol 2022; 11:766576. [PMID: 35096575 PMCID: PMC8793058 DOI: 10.3389/fonc.2021.766576] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 12/21/2021] [Indexed: 12/30/2022] Open
Abstract
Background Taiwan is one of the endemic regions where upper tract urothelial carcinoma (UTUC) accounts for approximately a third of all urothelial tumors. Owing to its high prevalence, extensive experience has been accumulated in minimally invasive radical nephroureterectomy (RNU). Although a variety of predictive factors have been explored in numerous studies, most of them were on a single-center or limited institutional basis and data from a domestic cohort are lacking. Objective This study aims to identify significant predicting factors of oncological outcomes, including overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), and intravesical recurrence-free survival (IVRFS), following RNU for UTUC in Taiwan. Methods A multicenter registry database, Taiwan UTUC Collaboration Group, was utilized to analyze oncological outcomes of 3,333 patients undergoing RNU from 1988 to 2021 among various hospitals in Taiwan. Clinicopathological parameters were recorded according to the principles established by consensus meetings. The Kaplan-Meier estimator was utilized to estimate the survival rates, and the curves were compared using the stratified log-rank test. Univariate and multivariate analyses were performed with the Cox proportional hazard model to explore potential predicting factors. Results With a median follow-up of 41.8 months in 1,808 patients with complete information, the 5-year IVRFS, DFS, CSS, and OS probabilities were 66%, 72%, 81%, and 70%, respectively. In total, 482 patients experienced intravesical recurrence, 307 died of UTUC, and 583 died of any cause. Gender predominance was female (57%). A total of 1,531 patients (84.7%) had high-grade tumors; preoperative hydronephrosis presented in 1,094 patients (60.5%). Synchronous bladder UC was identified in 292 patients (16.2%). Minimally invasive procedures accounted for 78.8% of all surgeries, including 768 hand-assisted laparoscopic (42.5%) and 494 laparoscopic (27.3%) approaches. Synchronous bladder UC was the dominant adverse predicting factor for all survival outcomes. Other independent predicting factors for OS, CSS, and DFS included age ≧70, presence of preoperative hydronephrosis, positive surgical margin, LVI, pathological T and N staging, and laparoscopic RNU. Conclusion Synchronous UC of the urinary bladder is an independent adverse prognostic factor for survival in UTUC. The presence of preoperative hydronephrosis was also corroborated as a disadvantageous prognostic factor. Our multivariate analysis suggested that laparoscopic RNU might provide better oncological control.

[PMID: 34671552 PMCID: PMC8521060 DOI: 10.3389/fonc.2021.723669] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 09/09/2021] [Indexed: 11/24/2022] Open
Abstract
Introduction As a research team of urologists and an anesthetist, we sought to investigate the prognostic significance of American Society of Anesthesiologists (ASA) score in patients with upper tract urothelial cancer (UTUC) after radical nephroureterectomy (RNU). ASA physical status (ASA-PS) classification not only was found to be associated with increased comorbidities but also independently factors for predicting morbidity and mortality. Accurate risk assessment was being particularly important for patients being considered for surgery. Methods Records for 958 patients with UTUC who underwent RNU were reviewed. Clinicopathologic variables, including ASA-PS, were assessed at two institutions. Overall survival (OS), cancer-specific survival (CSS), intravesical recurrence-free survival (IRFS), and metastasis-free survival (MFS) were estimated using the Kaplan–Meier method and Cox regression analyses. We measured the independent predictive value of ASA-PS for mortality by multivariate regression. Association of ASA-PS and clinicopathologic variables was assessed. Results The group of patients with ASA = 2/3 had a shorter 5-year OS (67.6% and 49.9%), CSS (72.9% and 58.1%), and MFS (75.1% and 58.5%). The median follow-up time was 39 months. Kaplan–Meier curves showed that the group with ASA = 2/3 had significantly poorer OS, CSS, and MFS. Adjusting for multiple potential confounding factors, multivariate analyses suggested that ASA score was an independent predictor of OS, CSS, and MFS (p = 0.004, p = 0.005, p < 0.001). Conclusion Higher ASA scores were independently associated with lower survival rate. This capability, along with its simplicity, makes it a valuable prognostic metric. It should be seriously referenced in UTUC patients being considered for RNU.

Front Oncol 2021; 11:698594. [PMID: 34290988 PMCID: PMC8287585 DOI: 10.3389/fonc.2021.698594] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 06/23/2021] [Indexed: 02/02/2023] Open
Abstract
Background and Objectives Due to the inevitability of waiting time for surgery, this problem seems to have become more pronounced since the outbreak of COVID-19, and due to the high incidence of preoperative hydronephrosis in upper urinary tract urothelial carcinoma (UTUC) patients, it is particularly important to explore the impact of preoperative waiting time and hydronephrosis on upper urinary urothelial carcinoma. Methods 316 patients with UTUC who underwent radical surgery at a high-volume center in China between January 2008 and December 2019 were included in this study. We retrospectively collected the clinicopathologic data from the medical records, including age, sex, smoking history, ECOG performance status (ECOG PS), body mass index (BMI), tumor location and size, number of lesions, T stage, N stage, surgical approach and occurrence of hydronephrosis, lymph node invasion, lymph node dissection, surgical margin, tumor necrosis, infiltrative tumor architecture, lymphovascular invasion and concomitant bladder cancer. Surgical wait time was defined as the interval between initial imaging diagnosis and radical surgery of UTUC. Hydronephrosis was defined as abnormal dilation of the renal pelvis and calyces due to obstruction of the urinary system. Firstly, all patients were divided into short-wait (<31 days), intermediate-wait (31-90 days) and long-wait (>90 days) groups according to the surgical wait time. The clinicopathological characteristics of each group were evaluated and the survival was compared. For patients with hydronephrosis, we subsequently divided them into two groups: short-wait (≤60 days) and long-wait (>60 days) groups according to the surgical wait time. Univariate and multivariate COX regression analysis were performed to evaluate the prognostic risk factor for patients with hydronephrosis. Results A total of 316 patients with UTUC were included in this study with a median surgical wait time of 22 days (IQR 11-71 days). Of the 316 patients, 173 were classified into the short-wait group (54.7%), 69 into the intermediate-wait group (21.8%) and 74 into the long-wait group (23.5%). The median follow-up time for all patients was 43 months (IQR 28-67months). The median surgical wait times of the short-wait, intermediate-wait and long-wait group were12 days (IQR 8-17days), 42days (IQR 37-65days) and 191days (IQR 129-372days), respectively. The 5-year overall survival (OS) of all patients was 54.3%. The 5-year OS of short-wait, intermediate-wait and long-wait groups were 56.4%, 59.3% and 35.1%, respectively (P=0.045). The 5-year cancer-specific survival (CSS) of short-wait, intermediate-wait and long-wait groups were 65.8%, 70.9% and 39.6%, respectively (P=0.032). In the subgroup analysis, we divided 158 UTUC patients with hydronephrosis into short-wait group (≤60 days) and long-wait group (> 60 days), 120 patients were included in the short-wait group and 38 patients in the long-wait group. The median surgical wait times of the short-wait and long-wait group were 14days (IQR 8-28days) and 174days (IQR 100-369days), respectively. The 5-year OS of long-wait group was significantly lower than the OS of short-wait group (44.2% vs. 55.1%, P =0.023). The 5-year CSS of long-wait and short-wait group were 49.1% and 61.7%, respectively (P=0.041). In multivariate Cox regression analysis of UTUC patients with hydronephrosis, surgical wait time, tumor grade, pathological T stage, and tumor size were independent risk factors for OS and CSS. Lymph node involvement was also a prognostic factor for CSS. Conclusion For patients with UTUC, the surgical wait time should be limited to less than 3 months. For UTUC patients with hydronephrosis, the OS and CSS of patients with surgical wait time of more than 60 days were relatively shorted than those of patients with surgical wait time of less than 60 days.
