RESUMEN

AIM: Intravesical recurrence (IVR) after nephroureterectomy for upper tract urothelial carcinoma (UTUC) is relatively frequent, occurring in about 30-50% of patients. The aim of this study was to investigate the differences of the prognosis and IVR between open and laparoscopic surgery and to elucidate the risk factor of IVR. PATIENTS AND METHODS: We retrospectively analyzed data from 403 patients with UTUC treated with laparoscopic or open nephroureterectomy at six affiliated hospitals between 1990 and 2015. The clinicopathological factors of each group were examined using Kaplan-Meier plots, and univariate and multivariate analyses. RESULTS: There was no difference in recurrence and cancer-specific mortality between open and laparoscopic surgery in univariate and multivariate analyses. There was no significant difference in IVR rate between the laparoscopic and open groups (p = .22). Among the patients with IVR, 84% of patients relapsed within 2 years. Univariate analysis of IVR showed a significant increase in patients with low-grade (p = .03, HR = 1.64) or low-stage urothelial carcinoma (pT1 or lower, p = .006, HR = 1.77) with no lymph node involvement (p = .002, HR = 10.3) or lymphovascular invasion (p = .009, HR = 1.79). Surgical modality was not an independent factor. In multivariate analysis, there was no independent predictive factor for IVR. CONCLUSIONS: There was no difference in recurrence, cancer-specific mortality, and IVR between open and laparoscopic surgery. On the other hand, our results suggested that the low malignant potential tumor may be a risk factor for IVR. This finding provides insight into IVR, which may help with the development of personalized prevention and treatment strategies.

RESUMEN

OBJECTIVE. IgG4-related disease is characterized by extensive infiltration of IgG4-positive plasma cells and fibrosis in various organs. The objective of this study is to investigate CT findings of IgG4-related lesions involving the upper urinary tract and compare them with those of urothelial carcinomas. MATERIALS AND METHODS. This study reviewed pretreatment CT images of 13 consecutive patients with IgG4-related disease with upper urinary tract lesions and 80 consecutive patients with urothelial carcinomas. The findings assessed were laterality, location, growth pattern, margins, internal structure, presence of calcification and lipid component, enhancement pattern, and extraurinary findings. RESULTS. Bilaterality (p < 0.0001), an extramural growth pattern (p < 0.0001), a greater number of affected segments (p = 0.04), and a gradual dynamic enhancement pattern (p < 0.001) were significantly more frequent in patients with IgG4-related disease. With regard to extraurinary findings, paraaortic fat stranding (p = 0.03), presacral fat stranding (p < 0.001), fat stranding of the pelvic walls (p < 0.001), and aortic involvement (p < 0.001) were seen more frequently in patients with IgG4-related disease; on the other hand, there was no statistically significant difference in terms of frequency of pancreatic involvement. Hydronephrosis and renal involvement were seen more frequently in patients with urothelial carcinoma, although the difference was not statistically significant. CONCLUSION. CT findings suggestive of IgG4-related upper urinary tract lesions in comparison with urothelial carcinoma are bilateral and have a longer urinary tract involvement and exhibit an extramural growth pattern, ill-defined margins, a gradual enhancement pattern, aortic involvement, and fat stranding in the paraaortic, presacral, or pelvic wall areas.

RESUMEN

BACKGROUND The treatment of inflammatory bowel disease aims to induce and maintain disease remission, avoid complications, and restore quality of life. The treatments include the use of immunosuppressants and biological therapy. Despite the effectiveness of these treatments in controlling disease activity and in limiting complications, there remains an increased risk of developing malignancies. CASE REPORT A 70-year-old male patient with ulcerative colitis who had pancolitis was initially treated with mesalazine. In 2010, the medication was changed to azathioprine due to clinical disease activity. The patient demonstrated clinical and endoscopic response to the medication, but presented recurrent facial lesions identified as non-melanoma skin cancer in 2014, 2015, and 2016. Azathioprine was discontinued and anti-TNF therapy was started, but no satisfactory clinical or endoscopic response was observed. The patient developed hematuria and a ureter tumor was found with subsequent ureteronephrectomy. Moreover, the patient underwent total colectomy with ileostomy as a treatment for refractory ulcerative colitis. CONCLUSIONS Immunosuppressive therapy can facilitate the development of malignant neoplasms, accelerate tumor growth, and favor the onset of metastases. The types of tumors most associated with its use are lymphoproliferative tumors and non-melanoma skin cancer. The benefits of adequate control of inflammatory bowel disease are clear and the use of immunosuppressants should not be limited by these potential adverse outcomes; however, the risk-benefit profile of immunosuppression should always be assessed on a case-by-case basis.

RESUMEN

OBJECTIVES: Polymerase I and transcript release factor (PTRF) has been implicated in cancer biology but its role in upper tract urothelial carcinoma (UTUC) is unknown. From a pilot transcriptome, we identified PTRF was significantly upregulated in high stage UTUC. Bladder cancer transcriptome from The Cancer Genome Atlas (TCGA) supported our finding and high PTRF level also predicted poor survival. We, therefore, investigated the correlation of PTRF with patients' clinicopathologic characteristics and outcomes in a multiracial UTUC cohort. MATERIALS AND METHODS: By immunohistochemical staining, PTRF expression was determined using H-score. PTRF expression of 575 UTUCs from 8 institutions, including 118 Asians and 457 Caucasians, was compared with various clinicopathologic parameters. Human urothelial cancer cell lines were used to evaluate the level of PTRF protein and mRNA expression, and PTRF transcript level was assessed in fresh samples from 12 cases of the cohort. The impact of PTRF expression on disease progression, cancer-specific death and overall mortality was also examined. RESULTS: High PTRF expression was significantly associated with multifocality (P = 0.023), high pathologic tumor stage (P < 0.00001), nonurothelial differentiation (P = 0.035), lymphovascular invasion (P = 0.003) and lymph node metastasis (P = 0.031). PTRF mRNA expression was also markedly increased in advanced stage UTUC (P = 0.0003). High PTRF expressing patients had consistently worse outcomes than patients with low PTRF expression regardless of demographic variation (all P < 0.005). In multivariate analysis, high PTRF expression was an independent predictor for progression-free survival (hazard ratio [HR] 1.70, 95% confidence interval [CI] 1.07-2.69, P = 0.025), cancer-specific survival (HR 2.09, 95% CI 1.28-3.42, P = 0.003), and overall survival (HR 2.04, 95% CI 1.33-3.14, P = 0.001). CONCLUSIONS: Results indicate that PTRF is a predictive biomarker for progression and survival and an independent prognosticator of UTUC. Elevated PTRF could probably propel clinically aggressive disease and serve as a potential therapeutic target for UTUC.

RESUMEN

RATIONALE: Primary carcinosarcoma of the upper urinary tract is rare. Ureteral duplication is one of the most common urinary tract malformations. Additionally, the association between ureteral duplication and malignancy is unknown. To the best of our knowledge, no cases of malignant tumors diagnosed as carcinosarcoma with ureteral duplication have been reported. We herein report the case of a patient with carcinosarcoma of the ureteropelvic junction associated with incomplete ureteral duplication. PATIENT CONCERNS: A 60-year-old Japanese woman presented with painless gross hematuria. She had a history of total hysterectomy and chemotherapy for endometrioid carcinoma 5 years before. She had no history of occupational chemical exposure. DIAGNOSES: Radiographic imaging revealed right incomplete ureteral duplication, hydronephrosis, and a polypoid tumor in the ureteropelvic junction of the lower moiety of the right kidney. Urine cytology showed a small amount of degenerated atypical epithelial and nonepithelial cells. The transureteral biopsy specimen showed dysplastic urothelial cells and atypical myoid spindle cells. These findings were indefinite for malignancy. INTERVENTIONS: The patient underwent right nephroureterectomy. Pathological examination of the resected tumor showed a biphasic neoplasm composed of carcinomatous and sarcomatous components. The sarcomatous component was immunohistochemically positive for vimentin, desmin, h-caldesmon, and α-SMA and negative for pancytokeratin (AE1/AE3), low molecular weight cytokeratin (CAM 5.2), EMA, E-cadherin, GATA3, uroplakin 2, and p63. Based on these findings, we diagnosed the tumor as carcinosarcoma. OUTCOMES: The postoperative course was uneventful. No additional therapy was administered. The patient has remained alive without recurrence for 21 months since surgery. LESSONS: Carcinosarcoma can arise from ureteral duplication. Although the majority of carcinosarcomas of the upper urinary tract are diagnosed at an advanced stage and have a poor prognosis, some can have a less aggressive course. Further studies are needed to determine the association between ureteral duplication and malignancy.

RESUMEN

PURPOSE OF REVIEW: Our aim is to review recent investigations into the recurrence of urothelial carcinoma in the upper urinary tract following bladder cancer therapy focusing on surveillance and management. RECENT FINDINGS: After radical cystectomy, rates of recurrence in the upper tract are between 0.75 and 6.4%. The poor prognosis of upper tract urothelial carcinoma (UTUC) is in part attributable to delayed diagnosis. Guidelines recommend a gradual de-escalation of surveillance in disease-free patients with the potential for discontinuation beyond 5 years. Previous guideline audits have shown that recurrences are still missed, suggesting a need for longer follow-up. Studies propose risk stratifying patients by age, comorbidities, and tumor stage to warrant closer surveillance and identify adjuvant therapy candidates. Larger studies are needed to advise treatment of UTUC after a urothelial bladder cancer (UBC) diagnosis, as these patients face poorer outcomes following radical nephroureterectomy. Clinical trials have demonstrated the efficacy of neoadjuvant and adjuvant systemic therapy after radical nephroureterectomy for primary UTUC; however, the literature is lacking robust data on patients who develop urothelial carcinoma in the upper tract following an initial UBC diagnosis. SUMMARY: Many asymptomatic recurrences of urothelial carcinoma in the upper tract are undetected by current surveillance guideline recommendations. Higher level evidence is needed to confirm the efficacy of prolonged and risk-adapted surveillance of patients with UBC and the extirpative management of recurrence in the upper tract after UBC treatment.

RESUMEN

Urothelial carcinoma in the upper tract is rare and often discussed separately. Many established risk factors were identified for the disease, including genetic and external risk factors. Radiographic survey, endoscopic examination and urine cytology remained the most important diagnostic modalities. In localized upper tract urothelial carcinomas, radical nephroureterectomy with bladder cuff excision are the gold standard for large, high-grade and suspected invasive tumors of the renal pelvis and proximal ureter, whereas kidney-sparing surgeries should be considered in patients with low-risk disease. Advances in technology have given endoscopic surgery an important role, not only in diagnosis, but also in treatment. Although platinum-based combination chemotherapy is efficacious in advanced or metastatic disease, current established chemotherapy regimens are toxic and lack a sustained response. Immune checkpoint inhibitors have led to a new era of treatment for advanced or metastatic urothelial carcinomas. The remarkable results achieved thus far show that immunotherapy will likely be the future treatment paradigm. The combination of immune checkpoint inhibitors and other agents is another inspiring avenue to explore that could benefit even more patients. With respect to the high incidence rate and different clinical appearance of upper tract urothelial carcinomas in Taiwan, a possible correlation exists between exposure to certain external risk factors, such as arsenic in drinking water and aristolochic acid in Chinese herbal medicine. As more gene sequencing differences between upper tract urothelial carcinomas and various disease causes are detailed, this has warranted the era of individualized screening and treatment for the disease.

RESUMEN

INTRODUCTION: Primary small cell carcinoma (SCC) after renal transplantation is very rare. Here, we reported 1 case of primary SCC after renal transplantation and analyzed its clinical and pathological characteristics. CASE PRESENTATION: A 55-year-old female underwent renal transplantation in our hospital 2 years ago and had been using tacrolimus for immunosuppressive therapy. Because of abdominal distention, the patient was admitted to our hospital. Computed tomography (CT) showed a malignant tumor of left kidney. Patient underwent surgical treatment and radical nephrectomy and lymph node dissection were selected. Postoperative pathological diagnosis was primary renal parenchyma and ureteral SCC. The patient has been treated with combination chemotherapy of lowpol (100 mg per day) and etoposide (10 mg per day). His vital signs are stable now, and he is receiving further treatment in our hospital. CONCLUSION: Because of immunosuppressive drugs use, the incidence of malignancies has increased significantly after renal transplantation. This case highlights the difficulty of diagnosis of primary SCC and the necessity of checking for neuroendocrine tumor after organ transplantation.

RESUMEN

Lynch syndrome confers an increased risk for urothelial carcinoma (UC). Molecular subtypes may be relevant to prognosis and therapeutic possibilities, but have to date not been defined in Lynch syndrome-associated urothelial cancer. We aimed to provide a molecular description of Lynch syndrome-associated UC. Thus, Lynch syndrome-associated UCs of the upper urinary tract and the urinary bladder were identified in the Danish hereditary nonpolyposis colorectal cancer (HNPCC) register and were transcriptionally and immunohistochemically profiled and further related to data from 307 sporadic urothelial carcinomas. Whole-genome mRNA expression profiles of 41 tumors and immunohistochemical stainings against FGFR3, KRT5, CCNB1, RB1, and CDKN2A (p16) of 37 tumors from patients with Lynch syndrome were generated. Pathological data, microsatellite instability, anatomic location, and overall survival data were analyzed and compared with sporadic bladder cancer. The 41 Lynch syndrome-associated UC developed at a mean age of 61 years with 59% women. mRNA expression profiling and immunostaining classified the majority of the Lynch syndrome-associated UC as urothelial-like tumors with only 20% being genomically unstable, basal/SCC-like, or other subtypes. The subtypes were associated with stage, grade, and microsatellite instability. Comparison to larger datasets revealed that Lynch syndrome-associated UC shares molecular similarities with sporadic UC. In conclusion, transcriptomic and immunohistochemical profiling identifies a predominance of the urothelial-like molecular subtype in Lynch syndrome and reveals that the molecular subtypes of sporadic bladder cancer are relevant also within this hereditary, mismatch-repair defective subset.

RESUMEN

BACKGROUND: We present a case of asynchronously occurring adenocarcinomas 29 and 36 years after ureterosigmoidostomy for bladder cancer, respectively, at both anastomosis sites. CASE PRESENTATION: A colonoscopy that was performed on a 69-year-old man because of bloody stool and an elevated carcinoembryonic antigen (CEA) level revealed a polypoid lesion at the right ureterosigmoid anastomosis site 29 years after the patient's ureterosigmoidostomy. Endoscopic resection was performed, and the lesion was diagnosed as adenocarcinoma. Seven years later (36 years after ureterosigmoidostomy), an elevated lesion was detected at the left ureterosigmoid anastomosis site by colonoscopy performed after detection of high CEA levels. Biopsy revealed an adenocarcinoma that was immunohistologically positive for CDX2; sigmoidectomy and ureterectomy were subsequently performed. The pathological diagnosis of the second tumor was adenocarcinoma arising in the ureterosigmoid anastomosis site and invading the left ureter. CONCLUSIONS: Diligent long-term follow-up of patients who underwent ureterosigmoidostomy is essential.

RESUMEN

PURPOSE: Although cigarette smoking is a well established risk factor for urothelial cancer, its role in urothelial cancer prognosis is still undetermined. In this meta-analysis we quantify the role of lifetime smoking history in bladder cancer recurrence, progression and survival by pooling available data on nonmuscle invasive bladder cancer, muscle invasive bladder cancer and upper tract urothelial carcinoma. MATERIALS AND METHODS: A total of 24 studies, comprising data from 13,114 patients with bladder cancer and 2,259 patients with upper tract urothelial carcinoma, were included in this meta-analysis. Publication bias was addressed through Egger's test, and the heterogeneity among studies was assessed by the I(2) test statistic and subgroup analyses. RESULTS: Current smokers at diagnosis are at increased risk for local recurrence in nonmuscle invasive bladder cancer (HR 1.27, 95% CI 1.09-1.46) and smokers with muscle invasive bladder cancer have an increased risk of dying of bladder cancer (HR 1.23, 95% CI 1.02-1.44). In the upper tract urothelial carcinoma population smokers have an increased risk of recurrence in the operative bed (HR 1.57, 95% CI 1.19-1.95) and of death from upper tract urothelial carcinoma (HR 1.53, 95% CI 1.13-1.92). We did not identify significant heterogeneity among included studies. CONCLUSIONS: The body of evidence is limited due to the absence of prospective studies. However, the results from this meta-analysis unambiguously support the hypothesis that lifetime cigarette smokers are at increased risk for a more malignant type of urothelial carcinoma associated with a worse prognosis.

RESUMEN

The success of human kidney allotransplantation was realized over six decades ago. First described 50 years ago, renal autotransplantation has been utilized sparingly as a salvage procedure for patients at risk of losing renal function, either from a benign or malignant condition. While classically associated with colorectal malignancies, Lynch syndrome also carries a small yet significant risk for the development of ureteral carcinoma. For these patients who develop chronic kidney disease, allotransplantation may not be an option due to the lifelong risk of several malignancies. We report the first known case of renal autotransplantation in a patient with metachronous ureteral cancer due to Lynch syndrome.

RESUMEN

PURPOSE: To investigate the site-specific pattern of disease recurrence and/or metastasis and the associated patient outcomes after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC). METHODS: A total of 733 patients with UTUC from a retrospective multi-institutional cohort were included, with a median follow-up of 34 months. Associated patient outcomes were analyzed by multivariate analysis. To evaluate the influence of primary tumor location, we divided it into four areas: renal pelvis, and upper, middle, and lower ureter. RESULTS: A total of 218 patients experienced disease recurrence, with the majority of relapses occurring within the first 3 years. Cumulative incidence rates of first disease recurrence at 1 and 3 years were 18.9 and 29.8 %, respectively. Of these patients, 38.5 % developed distant recurrence; 17.4 % experienced both local and distant recurrences; and 44.0 % developed isolated local recurrence. The predominant sites of distant metastasis were lung, liver, and bone. Multivariate analysis revealed that the prevalence of local recurrence and lung metastasis was significantly associated, with primary tumor location being independent of other clinicopathological variables. Lower/middle ureter tumors had a higher rate of local recurrence in the pelvic cavity, and renal pelvic tumors had a higher prevalence of distant relapse in the lungs. Similar results were obtained when rerunning the data set by excluding patients who received adjuvant chemotherapy (n = 131). CONCLUSIONS: This multi-institutional study provided a detailed picture of metastatic behavior after RNU, and primary tumor locations were associated with unique patterns of metastatic spread in UTUC patients.

RESUMEN

PURPOSE: Upper urinary tract (pyelocalyceal cavities and ureter) urothelial carcinoma is a relatively rare neoplastic disease. Although diagnosis and treatment of this tumor variant have improved significantly, accurate risk stratification remains a challenge. To identify the putative oncogene involved in urothelial carcinoma progression we performed bioinformatics guided experimental investigation targeting chromosome 19q13. MATERIALS AND METHODS: We investigated the effects of EMP3 on cancer cell growth, migration and adhesion in transfection and siRNA experiments in vitro. Crosstalk of integrins or ErbB2 with EMP3 was examined by reverse transcriptase-polymerase chain reaction and immunoblot. The potential involvement of epigenetic alterations of EMP3 in vitro and in vivo was analyzed by methylation specific polymerase chain reaction. To validate clinical relevance we measured EMP3 expression at the mRNA and protein levels in a cohort of 77 patients with upper urinary tract urothelial carcinoma and compared prognostic significance in relation to that of ErbB2 expression. RESULTS: We noted functional crosstalk between ErbB2 and EMP3 in vitro. EMP3 over expression promoted cancer cell proliferation and migration but suppressed cell adhesion in vitro. EMP3 activated the ErbB2-PI3K-AKT pathway to increase cell growth in vitro. In the clinical cohort Kaplan-Meier survival estimates showed that ErbB2 and EMP3 co-expression was the most important indicator of progression-free and metastasis-free survival in patients with upper urinary tract urothelial carcinoma (log rank test p = 0.018 and 0.04, respectively). CONCLUSIONS: EMP3 is an important prognostic indicator for selecting patients with upper urinary tract urothelial carcinoma for more intensive therapy. EMP3 is an innovative co-targeting candidate for designing ErbB2 based cancer therapy.

RESUMEN

OBJECTIVE: Carcinoma of the renal pelvis and ureter are unusual tumours and our limited knowledge comes mainly from case reports and small series from large academic hospitals, as a rule without histopathological review. This study reports aetiological and demographical factors as well as clinicopathological findings of all patients in a large geographical region. MATERIAL AND METHODS: All patients in western Sweden with a renal pelvic or ureteral tumour diagnosed between 1971 and 1998 (n = 930) were included. Untreated cases were not excluded. Demographic data and results of preoperative examinations were retrieved from the original clinical records. The histopathological slides were reviewed and tumour stage, grade, configuration, presence of carcinoma in situ and angiolymphatic invasion were determined. RESULTS: The majority of patients (80%) had invasive or high-grade tumours. Carcinoma in situ was present among 30% of patients with non-invasive high-grade tumours. Angiolymphatic invasion (62%) and solid (non-papillary) growth pattern (84%) were very common among patients with stage T2-T4 tumours. Twenty-three women out of 138 (16.7%) with ureteral carcinoma had a history of abdominal radiotherapy for gynaecological cancer 22 years (median) earlier. Forty-one patients out of 930 (4.4%) had a history of abuse of phenacetin-containing analgesics. CONCLUSIONS: This study demonstrates a very high incidence of high-grade upper tract tumours with carcinoma in situ, angiolymphatic invasion and solid (non-papillary) growth pattern, which underscores the malignant character of the disease. The possible association between pelvic radiotherapy and ureteral carcinoma warrants further study.

RESUMEN

We report a case of urothelial carcinoma (UC) in a 69-year-old man that occurred after renal transplantation. He had started receiving hemodialysis therapy in 2004 due to diabetic nephropathy and underwent living related renal transplantation from his brother in 2005. He was referred to our hospital in May 2009 with asymptomatic microscopic hematuria. Cystoscopy findings revealed multiple bladder tumors, and transurethral resection of bladder tumor (TUR-BT) followed by intravesical instillation of pirarubicin was performed. Histopathological findings revealed UC (G1>G2, pTa). Cytology findings after the operation did not become negative; urine specimen from the native right ureter was positive, and abdominal computed tomography (CT) demonstrated a right pelvic tumor. In January 2010, a laparoscopic right nephroureterectomy was performed and pathological examination findings revealed UC in the right pelvis (G3>G2, INFß, pT3). In March 2010, recurrence of the bladder tumor was demonstrated as carcinoma in situ (CIS) of the bladder and left native ureter. In June 2010, a radical cystectomy with left nephroureterectomy and ileal conduit diversion were performed. One week after that operation, laboratory results revealed abnormal hepatic function and CT showed multiple liver metastases. The patient died in August 2010, 2 months after surgery.

RESUMEN

Despite a ban on the use of plants of the Aristolochia genus in herbal medicine, as they contain known carcinogens, urothelial carcinoma attributable to the use of this plant seems to be more common than previously thought.

RESUMEN

UNLABELLED: Study Type--Prognosis (cohort) Level of Evidence 2b. What's known on the subject? and What does the study add? Upper urinary tract urothelial carcinoma (UUT-UC) is a rare disease, usually treated by nephroureterectomy, occurring in a population with a median age of 70 years and with frequent tobacco use and other comorbidities. We know that the American Society of Anesthesiologists (ASA) score has prognostic value in urological oncology but this has not been assessed in UUT-UC. Using a multi-institutional French database, we have shown that the 5-year cancer-specific survival differed significantly between ASA 1, ASA 2 and ASA 3 patients (83.8%, 76.9% and 70.6%, respectively; P = 0.01). ASA status had a significant impact on cancer-specific survival in univariate and multivariate analyses, with a threefold higher risk of mortality at 5 years for ASA 3 compared with ASA 1 patients (P = 0.04). OBJECTIVE: • To evaluate the impact of American Society of Anesthesiologists (ASA) scores on the survival of patients treated with radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UUT-UC). PATIENTS AND METHODS: • A retrospective multi-institutional cohort study of the French collaborative national database of UUT-UC treated by RNU in 20 centres from 1995 to 2010. • The influence of age, gender and ASA score on survival was assessed using a univariable and multivariable Cox regression analysis with pathological features used as covariables. RESULTS: • Overall, 554 patients were included. The median follow-up was 26 months (10-48 months), and the median age was 69.5 years (61-76 years). In total, 114 (20.6%) patients were classified as ASA 1, 326 (58.8%) as ASA 2 and 114 (20.6%) as ASA 3. • The 5-year recurrence-free survival (P = 0.21) and metastasis-free survival (P = 0.22) were not significantly different between ASA 1 (52.8% and 76%), ASA 2 (51.9% and 75.3%) and ASA 3 patients (44.1% and 68.2%, respectively). • The 5-year cancer-specific survival differed significantly between ASA 1, ASA 2 and ASA 3 patients (83.8%, 76.9% and 70.6%, respectively; P = 0.01). • ASA status had a significant impact on cancer-specific survival in univariate and multivariate analyses, with a threefold higher risk of mortality at 5 years for ASA 3 compared with ASA 1 patients (P = 0.04). CONCLUSIONS: • ASA classification correlates significantly with cancer-specific survival after RNU for UUT-UC. • It is a further pre-operative clinical variable that can be incorporated into future risk prediction tools for UUT-UC to improve their accuracy.
