Abstract
Background An earlier systematic review and meta-analysis found that patients with a certain histological variant of upper tract urothelial carcinoma (UTUC) exhibited more advanced disease and poorer survival than those with pure UTUC. A difference in the clinicopathological UTUC characteristics of Caucasian and Japanese patients has been reported, but few studies have investigated the clinical impact of the variant histology in Japanese UTUC patients. Methods We retrospectively enrolled 824 Japanese patients with pTa-4N0-1M0 UTUCs who underwent radical nephroureterectomy without neoadjuvant chemotherapy. Subsequently, we explored the effects of the variant histology on disease aggressiveness and the oncological outcomes. We used Cox's proportional hazards models to identify significant predictors of oncological outcomes, specifically intravesical recurrence-free survival (IVRFS), recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). Results Of the 824 UTUC patients, 32 (3.9%) exhibited a variant histology that correlated significantly with a higher pathological T stage and lymphovascular invasion (LVI). Univariate analysis revealed that the variant histology was an independent risk factor for suboptimal RFS, CSS, and OS. However, significance was lost on multivariate analyses. Conclusions The variant histology does not add to the prognostic information imparted by the pathological findings after radical nephroureterectomy, particularly in Japanese UTUC patients.

Abstract
Background and Objective Upper tract urothelial carcinoma (UTUC) is a relatively rare malignancy and radical nephroureterectomy (RNU) with bladder cuff excision (BCE) is considered as the standard of care for high-risk non-metastatic disease. Loss of the renal unit secondary to RNU, especially in elderly patients, causes significant decline in overall renal function which in turn negatively impacts the overall survival (OS). Such radical surgeries can be spared in a select group of the patients with segmental ureterectomy (SU) or distal ureterectomy to salvage the ipsilateral kidney. In this article, we will review the oncological and renal function outcomes following such procedures. This review excludes endourologic procedures. Methods This is a non-systematic review of the published literature focusing on the nephron-sparing surgical alternatives for the management of UTUCs. The following texts were used for literature search: "nephron-sparing surgery", "segmental ureterectomy", "total ureterectomy", "partial nephrectomy", and "ileal ureter". We included the articles indexed in PubMed, written in English language, and published within the last 15 years. Key Content and Findings The main argument against the utilization of these procedures is the lack of high quality, level I evidence, which is due to the rarity of this disease and the rates of ipsilateral recurrences. Despite that, the evidence in support of these nephron-sparing surgical alternatives is increasing over time. Published literature including single/multi-centric studies & systematic reviews, suggests comparable oncological outcomes and significantly improved renal function preservation. Lymph node dissection (LND) at the time of nephron-sparing surgical alternatives is largely underutilized. Similarly, the role of neoadjuvant or adjuvant systemic chemotherapy following such procedures is also not established currently. Conclusions With comparable oncological outcomes while preserving renal function, the nephron-sparing surgical alternatives to RNU are gaining momentum. These options can be offered to patients with low volume, localized UTUC with imperative indication for renal preservation such as solitary kidney, compromised baseline, and expected significant decline in post-RNU renal function without compromising oncological principles during surgery.

Abstract
Background and Objective Upper tract urothelial carcinoma (UTUC) is a rare disease. The gold standard treatment is radical nephroureterectomy (RNU). Endoscopic management of UTUC has emerged as an alternative therapy that aims to preserve kidney function while providing effective oncologic control. Over the years, this has become an increasingly important alternative to RNU for treating UTUC in patients with localized disease. Advancements in lasers and endoscopic technology have continued to expand the applications of endoscopic nephron-sparing treatment. This review aims to provide an overview of the available lasers and ureteroscopic technologies used in treating UTUC with a focus on their clinical applications and outcomes. Methods A comprehensive literature review was completed using PubMed to create this narrative mini review. Publications from peer-reviewed journals written in English between 1987 to 2022 were evaluated by the authors for inclusion. Key Content and Findings Improvements in ureteroscopic technology have led to improved visualization and tumor detection. Laser ablation using different laser energies including the holmium/yttrium-aluminum-garnet, neodymium/YAG, and thulium/YAG has demonstrated promising oncologic outcomes. However, accurate staging and risk-stratification remain limitations to the role of laser ablation for the treatment of UTUC. This review also highlights appropriate patient selection as a critical component of successful endoscopic management. Conclusions The continued evolution of endoscopic management will rely on the development of new technologies to improve risk stratification and oncologic outcomes. Overall, this review provides insights into the available laser therapies and ureteroscopic technologies for the endoscopic management of UTUC.

Abstract
Localized upper tract urothelial carcinoma (UTUC) is a difficult disease for clinicians to treat, due to the multitude of oncological and patient factors to consider. Despite the challenges of diagnostic staging, endoscopic management, and disease recurrence, there is still a need for local therapeutic options that do not subject patients to the morbidities of radical nephroureterectomy (RNU). Intraluminal chemotherapies have allowed for improved oncological control in patients with low-grade disease receiving renal-sparing treatment approaches. This narrative review discusses the treatment modalities available for localized low-grade UTUC, with a focus on the current status of chemoablation. The OLYMPUS trial was a pivotal study that lead to the Food and Drug Administration (FDA) approval of UGN-101 (mitomycin-C) in April 2020 for the treatment of low-grade UTUC, and intraluminal chemotherapy is now a widely used modality for managing this disease. The trial reported a complete response (CR) rate of 59%, and an estimated treatment durability of 82% at 1 year. However, a concern was the reported 44% ureteral stricture rate using the retrograde approach. More research is currently underway to determine the ideal instillation method for intraluminal therapies (e.g., retrograde vs. antegrade). Lastly, we discuss upcoming treatment options. Newer novel agents like padeliporfin vascular targeted photodynamic (VTP) therapy (brand name TOOKAD) are currently being studied, which will in hope provide additional treatment options for UTUC patients.

Abstract
Upper tract urothelial carcinoma (UTUC) is a relatively rare disease that presents unique challenges to urologists from both a diagnostic and management standpoint. UTUC is a clinically heterogenous disease with a varied natural history, and given its location in the upper urinary tract, treatment has the potential to cause or worsen chronic kidney disease. Therefore, physicians caring for patients with UTUC must be facile with multiple diagnostic and therapeutic strategies in order to provide optimal patient care. We present an overview of the epidemiology, histology, risk factors, and contemporary approach to the diagnosis, laboratory evaluation, imaging, and risk stratification for patients with UTUC. Computerized tomographic urography, thorough endoscopic evaluation, and biopsy (endoscopically or percutaneously) remain the standard of care for the diagnosis and staging of patients with suspected UTUC. Preoperative nomograms are vital to select patients more optimally for preoperative systemic chemotherapy and facilitate clinical trial enrollment. A thorough understanding of the various diagnostic challenges, imaging/pathologic limitations, biomarkers, and risk stratification tools will allow us as a field to develop new modalities to improve our diagnostic capabilities and reduce the risk of under diagnosis and over treatment for our patients.

Abstract
Background and Objective Although upper tract urothelial carcinoma (UTUC) shares the histological appearance of urinary bladder cancer (UBC), molecular studies suggest that UTUC and UBC represent two distinct disease entities. However, treatment approaches for UTUC are virtually extrapolated from the evidence on UBC. As targeted drugs-immune-checkpoint inhibitors, fibroblast growth factor receptor inhibitors, and antibody-drug conjugates-target specific molecules, gaining more knowledge about the target-molecular profiles of each drug can help formulate optimal treatment strategies for UTUC. Methods This narrative review summarized the subgroup analyses of clinical trials of FDA-approved targeted drugs to explore the differential effects of each targeted drug when administered for UTUC compared to UBC. We focused on the differences in mutation frequency, RNA expression subtype, and therapeutic target protein expressions (specifically PD-L1, Nectin-4, and Trop-2) between UTUC and UBC and discussed their relationship with the efficacy of each targeted drug. Key Content and Findings A clinical trial of nivolumab in an adjuvant setting (CheckMate 274) implied that immune-checkpoint inhibitors might be less efficacious in UTUC than in UBC. Genomic and transcriptomic studies suggest that UTUC has a high frequency of FGFR3 mutations and predominantly shows the luminal papillary subtype, which is immunologically cold with low T-cell infiltration. These findings are consistent with a possible lower response rate to immunotherapy in UTUC than that in UBC. Clinical trials of enfortumab vedotin in a third-line setting (EV201 and EV301) implied that enfortumab vedotin might be less efficacious in UTUC than in UBC. Previous immunohistochemical analyses suggest that UTUC might have a slightly lower rate of Nectin-4 positivity than UBC, indicating that enfortumab vedotin was less efficacious in UTUC than in UBC. Conclusions Clinical differences in the effects of targeted drugs for UTUC and UBC may highlight the molecular differences between these diseases. The treatment strategy should be optimized based on further investigation of the molecular characteristics of UTUC.

Abstract
Background B7 homolog 4 (B7-H4) is a negative regulator of immune responses, but its immunoregulatory role in the tumor microenvironment of upper urinary tract urothelial carcinoma (UTUC) remains unclear. Methods We measured the immunohistochemical expression of B7-H4, CD8 and T cell intracellular antigen 1 (TIA-1), a marker of activated CD8, in 133 patients with UTUC who underwent nephroureterectomy. We also studied the relationship between B7-H4, CD8 and TIA-1 expression and clinicopathological characteristics. Results B7-H4 was mainly expressed on the surface in tumor cells, while CD8 and TIA-1 were often expressed in tumor-infiltrating lymphocytes. Elevated expression of B7-H4 in tumor cells was associated with a poorer histological grade, higher pT stage, regional lymph node metastasis, lymphovascular invasion, poorer response of recurrent metastatic lesions to systemic chemotherapy and shorter overall survival. Expression of CD-8 or TIA-1 alone did not correlate directly with clinicopathological characteristics, but among the patients with higher B7-H4 expression in the primary tumors, those with higher CD8 or TIA-1 expression had a better response to systemic chemotherapy, and longer survival, than these with lower CD8 or TIA-1 expression. Cox multivariate regression analysis revealed that higher expression of B7-H4 was associated with shorter overall survival. Conclusions These findings suggest that B7-H4 expression in the tumor microenvironment influences the progression of UTUC through cancer immunity and metabolic activity. Tumor cell-associated B7-H4 might be a potential target for cancer immunotherapies.

Abstract
Urothelial carcinoma is one of the most common cancers in the United States, yet outcomes are historically suboptimal. Since 2016, the approval of five programmed cell death 1 and programmed death-ligand 1 immune checkpoint inhibitors for locally advanced and metastatic urothelial carcinoma has led to improved oncologic outcomes for many patients in the second-line setting. Two checkpoint inhibitors, pembrolizumab and atezolizumab subsequently earned approval for first-fine therapy with restricted indications. More recently, pembrolizumab was approved for bacillus Calmette-Guérin-unresponsive high-risk non-muscle invasive bladder cancer, opening the door for other immune checkpoint inhibitors to be integrated into treatment in earlier disease stages. Recent bacillus Calmette-Guérin shortages have highlighted the need for alternative treatment options for patients with non-muscle invasive bladder cancer. Currently, there are no FDA-approved checkpoint inhibitors for non-metastatic muscle-invasive bladder cancer. Furthermore, many patients are ineligible for standard cisplatin-based chemotherapy regimens. Numerous ongoing clinical trials are employing immune checkpoint inhibitors for muscle-invasive bladder cancer patients in the neoadjuvant, adjuvant, perioperative, and bladder-sparing setting. Although up to 10% of urothelial carcinoma tumors arise in the upper urinary tract, few studies are designed for this population. We highlight the need for more trials designed for patients with upper tract disease. Overall, there are numerous clinical trials investigating the safety and efficacy of immune checkpoint inhibitors in all stages of disease as single-agents and combined with dual-immune checkpoint inhibition, chemotherapy, radiotherapy, and other pharmacologic agents. As the field continues to evolve rapidly, we aim to provide an overview of recent and ongoing immunotherapy clinical trials in urothelial carcinoma.

Abstract
Purpose Ureteroscopy is an efficient endoscopic minimally invasive technique for the diagnosis and treatment of upper tract urothelial carcinoma. During ureteroscopy, the automatic segmentation of the hollow lumen is of primary importance, since it indicates the path that the endoscope should follow. In order to obtain an accurate segmentation of the hollow lumen, this paper presents an automatic method based on convolutional neural networks (CNNs). Methods The proposed method is based on an ensemble of 4 parallel CNNs to simultaneously process single and multi-frame information. Of these, two architectures are taken as core-models, namely U-Net based in residual blocks (\documentclass[12pt]{minimal}

Abstract
Upper tract urothelial carcinoma (UTUC) is a rare malignant disease, and while locally advanced non-metastatic UTUC can be cured by radical nephroureterectomy (RNU), this procedure leaves patients at high risk of relapse and death from cancer. Though the FDA has currently approved five agents for the systemic immunotherapy treatment of urothelial carcinoma (UC) patients, the effect of immunotherapy in patients with recurrent UTUC still lacks specific evidence. Camrelizumab is a programmed cell death protein 1 (PD-1) inhibitor which has been approved for the treatment of recurrent or refractory classical Hodgkin lymphoma in China and have achieved improvement in a verity of solid tumors with manageable safety profile. We herein report a case of an 80-year-old woman diagnosed with localized UTUC (pT4N0M0) for which she underwent RNU but relapsed after 2 months. As the toxic effects of chemotherapy were intolerable for the patient, she received the PD-1 inhibitor Camrelizumab as a salvage treatment to stop tumor growth. The tumor shrank and the patient achieved partial response (PR) after eight cycles but progressed after 14 cycles. Based on the current evidence, our case indicated that Camrelizumab is a promising agent in treating locally advanced and recurrent UTUC patients with poor performance status and imparted renal function.

Abstract
Upper tract urothelial carcinoma (UTUC) often occurs in elderly patients with multiple co-morbidities including renal impairment. As such, nephron sparing surgery (NSS) often needs to be considered. This article reviews the available NSS techniques for UTUC, including ureteroscopy, percutaneous approaches and segmental ureterectomy. PubMed and OvidMEDLINE reviews of available case series from the last 10 years demonstrated that recurrence was highly variable between studies and occurred in 19–90.5% of ureteroscopic cases, 29–98% of percutaneous resections and in 10.2–31.4% of patients who underwent segmental ureterectomy. The small number of included studies and variable follow up periods made comparison between techniques difficult. NSS is a necessary alternative for patients with significant comorbidities or renal impairment who cannot undergo radical nephro-ureterectomy. However, there is significant variation in oncological outcomes, with an increased risk of progression or death from cancer—salvage by radical surgery may sometimes be required.

Abstract
Background The outcome of neoadjuvant chemotherapy (NAC) has been established in bladder cancer but remains controversial in upper tract urothelial carcinoma (UTUC). In this work, we explored the therapeutic effect of NAC in patients with locally advanced UTUC. Methods We conducted a literature search on articles published from 1995 up to April 2020 in PubMed/Medline, the Cochrane Library, Embase, Google Scholar. A total of 19 eligible studies with 6,283 patients were identified, from which the overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), disease-free survival (DFS), pathological complete response (pCR) rate and pathological partial response (pPR) rate were extracted. All analyses were conducted using Review Manager 5.3 and Stata statistical software (version 15). Results In total, 6,283 UTUC patients were included from 19 eligible studies out of which 1,474 patients received NAC and subsequent radical nephroureterectomy (RNU), whereas 4,809 patients received RNU only. Compared with single RNU, patients with NAC and subsequent RNU exhibited longer OS, CSS, PFS, DFS by hazard ratio (HR) 2.14 [95% confidence interval (CI): 1.75–2.63; P<0.001], HR 2.07 (95% CI: 1.49–2.87; P<0.001), HR 2.00 (95% CI: 1.42–2.83; P<0.001), and HR 3.76 (95% CI: 2.16–6.56; P<0.001). pCR rate and pPR rate of NAC are 0.10 (0.07–0.13) and 0.40 (95% CI: 0.32–0.49, P <0.001) respectively. Conclusions This work revealed that NAC and subsequent RNU provided better survival outcomes in patients with locally advanced UTUC when compared with single RNU.

Abstract
Upper tract urothelial carcinoma (UTUC) is a very uncommon disease that occupies for <5% of all urothelial cancers. Radical nephroureterectomy (RNU) remains the standard-of-care for UTUC; however, when patients with locally advanced UTUC are treated with RNU only, the recurrence rate is high. Therefore, perioperative chemotherapy has been proposed given the high systemic recurrence rate. Moreover, there is growing evidence that neoadjuvant chemotherapy (NAC) plays an important role in the treatment of UTUC. Several studies and meta-analyses have reported the beneficial effect of NAC on survival outcomes and pathologic downstaging of patients with UTUC. However, the recommendation of NAC for UTUC is primarily based on level 1 evidence that demonstrated a beneficial effect on survival outcomes in patients with bladder cancer. The chemotherapy regimen for patients with UTUC is also based on that used for patients with bladder cancer. Nevertheless, the use of NAC for UTUC has some limitations, including the possibility of overtreatment. Therefore, selection criteria for NAC are needed, as are further trials to identify the most suitable patients and validate its use in daily clinical practice.

Abstract
The role of lymphadenectomy (LND) at the time of radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) is controversial. The National Comprehensive Cancer Network guidelines recommend performing a template-based LND for high-risk primary tumors while the European guidelines state that it is not feasible to determine indication or extent of LND at the time of surgery for UTUC. Herein, we review the anatomic rationale for template-based LND, examine when a LND should be considered, and discuss the impact of LND on staging and survival outcomes.

Abstract
Background Radical nephroureterectomy (RNU) is the referent standard for managing bulky, invasive, or high grade upper-tract urothelial carcinoma (UTUC). The UTUC patient population, however, generally harbor medical comorbidities thereby placing them at risk of surgical complications. This study reviews a large international cohort of RNU patients to define the risk of major complications and preoperative factors associated with their occurrence. Methods Patients undergoing RNU at 14 academic medical centers between 2002 and 2015 were retrospectively reviewed. Preoperative clinical, demographic, operative, and comorbidity indices were recorded. The modified Clavien-Dindo index was used to grade complications occurring within 30 days of surgery. The association between preoperative variables and major complications occurring after RNU was determined by multivariable logistic regression. Results One thousand two hundred and sixty-six patients (707 men; 559 women) with a median age of 70 years and BMI of 27 kg/m2 were included. Over three-quarters of the cohort was white, 50.1% had baseline chronic kidney disease (CKD) ≥ stage III, 22.4% had a Charlson comorbidity index (CCI) score >5, and 17.1% had an Eastern Cooperative Oncology Group (ECOG) performance status ≥2. Overall, 413 (32.6%) experienced a complication including 103 (8.1%) with a major event. Specific distribution of major complications included 49 Clavien III, 44 Clavien IV, and 10 Clavien V. On univariate analysis, patient age (P=0.006), hypertension (P=0.002), diabetes mellitus (P=0.023), CKD stage (P<0.001), American Society of Anesthesiologists (ASA) score (P=0.022), ECOG (P<0.001), and CCI (P<0.001) all were associated with major complications. On multivariate analysis, ECOG ≥2 (OR 2.38, 95% CI, 1.46–3.90), P=0.001), CCI >5 (OR 3.45, 95% CI, 1.41–8.33, P=0.007), and CKD stage ≥3 (OR 3.64, P=0.008) were independently associated with major complications. Conclusions Major complications following RNU occurred in almost 10% of patients. Impaired preoperative performance status and baseline CKD are preoperative variables associated with these major post-surgical adverse event. These easily measurable indices warrant consideration and discussion prior to proceeding with RNU.

Abstract
Ureteroscopic methods have been rapidly evolving in the last several decades. With advances in flexible devices, optics and laser technologies, the endourologic surgeon has now the tools to treat high-volume tumors, in difficult locations, with good oncologic outcome. This makes radical nephroureterectomy unnecessary in some cases. Endoscopy in the setting of UTUC will surely continue to evolve and become applicable to a wider selection of patients. In this review we describe the surgical technique and provide tips and tricks which we use in our practice of endoscopic retrograde treatment of upper-tract urothelial carcinoma.

Abstract
Though radical nephroureterectomy remains the gold standard treatment for high grade or invasive disease in upper tract urothelial cancer (UTUC), kidney-sparing surgery has become preferred for low risk disease, in order to minimize morbidity and preserve renal function. Many methods exist for endoscopic management, whether via an antegrade percutaneous or retrograde ureteroscopic approach, including electroresection, laser ablation, and fulguration. There has been an increase in use of adjuvant intracavitary therapy, predominantly using mitomycin and bacillus Calmette-Guerin (BCG), to reduce recurrence after primary endoscopic management for noninvasive tumors, although efficacy remains questionable. Intraluminal BCG has additionally been used for primary treatment of CIS in the upper tract, with around 50% success. Newer investigations include use of narrow band imaging or photodynamic diagnosis with ureteroscopy to improve visualization during diagnosis and treatment. Genomic characterization may improve selection for kidney-sparing surgery as well as identify actionable mutations for systemic therapy. The evolution in adjuvant management has seen strategies to increase the dwell time and the urothelial contact of intraluminal agents. Lastly, chemoablation using a hydrogel for sustained effect of mitomycin is under investigation with promising early results. Continued expansion of the armamentarium available and better identification and characterization of tumors ideal for organ-sparing treatment will further improve kidney preservation in UTUC.

Abstract
Background Marital status has been considered as an independent prognostic factor for various types of cancer survival. The objectives of our study were to investigate the function of marital status on the survival of upper tract urothelial carcinoma (UTUC) patients. Methods The patients diagnosed with UTUC between 1988 and 2015 were captured within the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified into married, divorced/separated, widowed and single cohorts. Kaplan-Meier and Cox regression analysis was conducted to assess the effects of marital status on overall survival (OS) and cancer-specific survival (CSS). A 1:1 matched‐pair analysis was performed to optimize the final statistical results by propensity score matching (PSM). Results Among the 10,852 eligible patients, the percentage of married, divorced/separated, widowed and single patients accounted for 58.2% (6,321), 9.0% (980), 23.3% (2,526) and 9.4% (1,025) respectively. The widowed patients had the worst OS and CSS. Marital status was a predictive factor for OS and CSS of UTUC patients. The results of multivariate Cox regression showed that the worst OS [hazard ratio (HR): 1.41; 95% confidence interval (CI): 1.33–1.49, P<0.001] and the poorer CSS (HR: 1.32; 95% CI: 1.22–1.43, P<0.001) were existed in the widowed patients, compared with married patients. The results of the stratified analysis by primary site also indicated the same conclusion. Furthermore, the results were confirmed in the 1:1 matched group. Conclusions Marital status acted as an independent prognostic and protective factor for survival in UTUC patients. Additionally, being widowed was related with a high risk of death in UTUC compared with married, divorced, or single patients.

Abstract
Upper tract urothelial carcinoma (UTUC) is a relatively uncommon and poorly investigated malignancy, however, bladder recurrence after radical nephroureterectomy (RNU) is a frequent event. In this review, we summarize the current knowledge on risk prediction of bladder tumor recurrence after RNU, including surgical strategies and adjuvant intravesical treatments to reduce the risk of recurrence. Finally, we outline some of the more recent advances in genomics that will likely lead to new prognostic markers and risk stratification tools that may refine UTUC treatment in the future.

Abstract
Background Increased expression of programmed cell death 1 ligand 1 (PD-L1) by tumor cells is thought to be a mechanism through which solid cancers promote immune tolerance. However, the association between PD-L1 expression and the prognosis of upper urinary tract urothelial carcinoma (UTUC) remains unknown. Methods We examined immunohistochemical PD-L1 expression and the tumor-infiltrating lymphocyte density (TILD) in 79 patients with UTUC who underwent nephroureterectomy. We classified the tumors into four types based on the combination of PD-L1 expression and TILD, and studied the clinicopathological characteristics of these four tumor types. Results Elevated expression of PD-L1 by tumor cells and a higher TILD were associated with a worse histological grade, higher pT stage, and higher peripheral blood neutrophil-to-lymphocyte ratio. Elevated expression of PD-L1 by tumor cells, a higher TILD, and type I, III, or IV tumors with elevated expression of either PD-L1 or TILD showed a positive correlation with poorer differentiation and local invasion. These three variables were associated with shorter progression-free survival and overall survival in univariate analysis, but only the latter was an independent determinant according to multivariate analysis. The patients who had type II tumors with lower PD-L1 expression and a lower TILD showed more favorable survival than the other three groups. Conclusions These findings suggest that PD-L1 expression and TILs in the tumor microenvironment influence the progression of UTUC. Accordingly, it is important to understand the immunologic characteristics of the tumor microenvironment to develop more effective treatment strategies for this cancer.

Abstract
Introduction Acute liver failure (ALF) secondary to malignant infiltration of the liver from urothelial carcinoma is a very rare clinical condition and is often diagnosed only after death. Upper tract urothelial carcinoma (UTUC) is a rare, from 5% to 10% of all urothelial tumours, but possible cause of ALF when there is extensive liver metastatic involvement. We report the case of a patient who died in the intensive care unit (ICU) of our hospital from multiple organ failure (MOF) secondary to ALF, as a result of infiltration of the liver from UTUC diagnosed after surgery. PRESENTATION OF THE CASE: A 69-year-old Caucasian man was referred to our hospital for hematuria, melena, right upper quadrant (RUQ) pain and jaundice developed over the previous two weeks. After multidisciplinary discussion, he underwent emergency exploratory laparotomy to perform cholecystectomy because of suspected acute cholecystitis considered as a septic focus within the left kidney. He developed MOF and died on the 6th postoperative day. Discussion From the diagnosis of the renal mass and the death of the patient, a few days have passed, and the diagnosis of UTUC has been put only at histological examination.The most common sites of metastases from UTUC are lymph nodes, lungs, liver, bones and peritoneum. Moreover, liver metastases have been identified to have an independent negative impact on overall survival in a patient affected by UTUC. Conclusion The authors suggest that this condition should be taken into account when dealing with patients with evidence of a renal mass and simultaneous ALF. Unusual clinical presentation of acute liver failure from upper urothelial carcinoma (UTUC). Rarely these diseases are managed in the emergency setting. This condition should be taken into account when dealing with patients with evidence of a renal mass and simultaneous ALF.

Abstract
The key prognostic factor at the time of diagnosis of upper tract urothelial carcinomas (UTUC) is whether the tumor is in the muscle-invasive or non-muscle invasive stage. It is critical to identify novel molecular biomarkers for early detection and target therapy. Plasma proteins secreted by tumor tissues have excellent potential as biomarkers for UTUC. In this study, we conducted a systematic study to identify plasma markers for UTUC based on RNA-seq data from five UTUC tissues and paired adjacent noncancerous mucosa. Through bioinformatics analysis, we found secreted phosphoprotein 1 (SPP1) was the most significant gene that coding secretory protein. Then, qRT-PCR and enzyme-linked immunosorbent assay were performed to evaluate the expression and clinical significance of SPP1 in UTUC. Results found that SPP1 mRNA was upregulated in UTUC cells and tissues, and high SPP1 mRNA expression level was closely related to advanced stage and high grade. Moreover, it is suggested that plasma SPP1 may be a potential biomarker to help identify early-stage UTUC patients and predict invasive and high-grade UTUC. In conclusion, plasma SPP1 is a novel biomarker for UTUC.

Abstract
In the context of customized patient care for upper tract urothelial carcinoma (UTUC), decision-making could be facilitated by risk assessment and prediction tools. The aim of this study was to provide a critical overview of existing predictive models and to review emerging promising prognostic factors for UTUC. A literature search of articles published in English from January 2000 to June 2016 was performed using PubMed. Studies on risk group stratification models and predictive tools in UTUC were selected, together with studies on predictive factors and biomarkers associated with advanced-stage UTUC and oncological outcomes after surgery. Various predictive tools have been described for advanced-stage UTUC assessment, disease recurrence and cancer-specific survival (CSS). Most of these models are based on well-established prognostic factors such as tumor stage, grade and lymph node (LN) metastasis, but some also integrate newly described prognostic factors and biomarkers. These new prediction tools seem to reach a high level of accuracy, but they lack external validation and decision-making analysis. The combinations of patient-, pathology- and surgery-related factors together with novel biomarkers have led to promising predictive tools for oncological outcomes in UTUC. However, external validation of these predictive models is a prerequisite before their introduction into daily practice. New models predicting response to therapy are urgently needed to allow accurate and safe individualized management in this heterogeneous disease.

Abstract
In the last few years growing evidence highlighted the differences between upper tract urothelial carcinoma (UTUC) and urothelial bladder carcinoma (UBC) which cannot be explained solely by their different anatomical location. The aim of this review was to summarize current progress in UTUC research and to underline the differences and similarities between UTUC and UBC by focusing on epidemiology, etiology, staging and risk factors as well as on surgical and medical management. UBC and UTUC sharing common risk factors such as smoking and aromatic amines, while aristolochic acid exposure or familiar Lynch syndrome are rather specific for UTUC. The grading of UBC and UTUC are identical, but inherent from their different anatomical locations, there are some differences between their stage classifications. As an example, in contrast to UBC where a clear recommendation for pT3 subclassification exists, in UTUC current research aims to define an adequate subclassification for pelvic pT3 cases aiming to provide a better risk stratification. The primary treatment for both UBC and UTUC is surgery. Similarly to UBC, UTUC patients at high risk of disease progression are treated by radical surgery. However, because of the inaccurate preoperative or transurethral staging of UTUC, many radical nephroureterectomies are performed unnecessarily. Preoperative prediction of pathological stage or patients' prognosis may reduce this overtreatment by selecting patients for nephron-sparing surgery. To this end, predictive models combining histological and molecular features together with imaging data may be used. The antegrade or retrograde instillation of BCG or mitomycin C, as topical agents is feasible after conservative treatment of UTUC or for the treatment of CIS. However, the prognostic significance of lymph node positivity in UTUC seems to be similar to that of UBC, the therapeutic benefit of lymph node dissection (LND) in UTUC has not been firmly established yet. In addition, the number of lymph nodes to be removed and the sequence of lymphadenectomy also remain to be defined. Systemic neoadjuvant and adjuvant chemotherapies appear to have beneficial effect on UTUC survival, however, this has to be confirmed by large prospective studies. Due to the intensive research of the last few years, our knowledge on UTUC has been largely improved, but many questions remained to be answered. Further research on the molecular background of UTUC holds the potential to identify prognostic or predictive markers which, together with imaging and histologic data, may help to overcome the inaccuracy of ureteroscopic endoscopy and may therefore help to improve therapeutic decision-making. Further, prospective studies should confirm the benefit of LND and adjuvant chemotherapy. Considering the low incidence of UTUC, conduction of such studies is difficult and may only be performed in a multicenter setting.

Abstract
Radical nephroureterectomy (RNU) is the gold standard treatment strategy for bulky, high-grade, or muscle-invasive upper tract urothelial carcinoma (UTUC). Many patients with UTUC who require RNU are elderly, comorbid, and at risk for perioperative complications. Recognition of likelihood and extent of such complications guides preoperative counseling, decision-making process for major surgery, and perioperative care. A critical review of such data is essential, given the inevitable impact of complications on hospital duration, need for readmission, resource utilization, and costs associated with management.

Abstract
PURPOSE To review the management of metastatic upper tract urothelial carcinoma (UTUC) including recent advances in targeted and immune therapies as an update to the 2014 joint international consultation on UTUC, co-sponsored by the Société Internationale d'Urologie and International Consultation on Urological Diseases. METHODS A PubMed database search was performed between January 2013 and May 2016 related to the treatment of metastatic UTUC, and 54 studies were selected for inclusion. RESULTS The management of patients with metastatic UTUC is primarily an extrapolation from evidence guiding the management of metastatic urothelial carcinoma of the bladder. The first-line therapy for metastatic UTUC is platinum-based combination chemotherapy. Standard second-line therapies are limited and ineffective. Patients with UTUC who progress following platinum-based chemotherapy are encouraged to participate in clinical trials. Recent advances in genomic profiling present exciting opportunities to guide the use of targeted therapy. Immunotherapy with checkpoint inhibitors has demonstrated extremely promising results. Retrospective studies provide support for post-chemotherapy surgery in appropriately selected patients. CONCLUSIONS The management of metastatic UTUC requires a multi-disciplinary approach. New insights from genomic profiling using targeted therapies, novel immunotherapies, and surgery represent promising avenues for further therapeutic exploration.

Abstract
Purpose Upper tract urothelial carcinoma (UTUC) is a rare and poorly investigated disease. Intense collaborative efforts have increased our knowledge and improved the management of the disease. The objective of this review was to discuss recent advances and unmet needs in UTUC. Methods A non-systematic Medline/PubMed literature search was performed on UTUC using the terms “upper tract urothelial carcinoma” with different combinations of keywords. Original articles, reviews and editorials in English language were selected based on their clinical relevance. Results UTUC is a disease with specific epidemiologic and risk factors different to urothelial carcinoma of the bladder (UCB). Similarly to UCB, smoking increases the risk of UTUC and worsens its prognosis, whereas aristolochic acid (AA) exposure and mismatch repair genes abnormality are UTUC specific risk factors. A growing understanding of biological pathways involved in the tumorigenesis of UTUC has led to the identification of promising prognostic/predictive biomarkers. Risk stratification of UTUC is difficult due to limitations in staging and grading. Modern imaging and endoscopy have improved clinical decision-making, and allowed kidney-sparing management and surveillance in favorable-risk tumors. In high-risk tumors, radical nephroureterectomy (RNU) remains the standard. Complete removal of the intramural ureter is necessary with inferiority of endoscopic management. Post-RNU intravesical instillation has been shown to decrease bladder cancer recurrence rates. While the role of neoadjuvant cisplatin based combination chemotherapy and lymphadenectomy are not clearly established, the body of evidence suggests a survival benefit to these. There is currently no evidence for adjuvant chemotherapy (AC) in UTUC. Conclusions Despite growing interest and understanding of UTUC, its management remains challenging, requiring further high quality multicenter collaborations. Accurate risk estimation is necessary to avoid unnecessary RNUs while advances in technology are still required for optimal kidney-sparing approaches.
