Abstract
INTRODUCTION Nephroureterectomy is commonly performed for high-grade (HG) upper tract (UT) urothelial carcinoma (UC). However, some patients may benefit from a de-escalation of surgical management, particularly for noninvasive disease and carcinoma in situ (CIS). Bacillus Calmette-Guerin (BCG) is currently the only guideline-recommended endoluminal treatment option. Gemcitabine/Docetaxel (Gem/Doce) has shown promising efficacy as a treatment for noninvasive HG UTUC, though a comparison to BCG is lacking. We report the outcomes of patients treated with endoluminal Gem/Doce vs. BCG for UT-CIS. METHODS A single-institutional retrospective review of patients treated with Gem/Doce vs. BCG for UT-CIS was performed. Treatment was instilled via nephrostomy or retrograde ureteral catheter. In both treatment groups, induction consisted of 6 weekly instillations. Maintenance was initiated if disease-free and consisted of 6 monthly instillations in the Gem/Doce group and a reduced dose (one-tenth) 3-week course at 3 months in the BCG group. Recurrence was defined as biopsy-proven disease or HG cytology. RESULTS The final cohort included 53 patients with 65 upper tract units; 31 received BCG and 34 received Gem/Doce. Median follow-up was 88 and 29 months in the BCG and Gem/Doce groups, respectively. Presenting pathology included biopsy-proven CIS and HG cytology in 9.7% and 90% of the BCG group, and 8.8% and 91% of the Gem/Doce group, respectively. The 2-year estimates for recurrence-free and nephroureterectomy-free survival were 61% and 89% for the BCG group and 54% and 100% for the Gem/Doce group, respectively. Upon multivariable analysis, instillation via percutaneous nephrostomy tube was associated with an increased risk of recurrence (HR 3.89, 95% CI 1.59-9.53). The development of any symptom was not statistically different between treatment groups (P = 0.12). There were 2 treatment-related deaths that occurred, 1 within each treatment group. CONCLUSION Endoluminal Gem/Doce and BCG have similar oncological outcomes and major adverse event rates in the treatment of UT-CIS. Further prospective evaluation is warranted.

Abstract
Primary carcinoma in situ (CIS) solely affecting the ureter without concurrent involvement of the kidney or bladder is an exceptionally rare condition. This case report presents the clinical management of a 67-year-old male patient with primary ureteral CIS, highlighting the diagnostic workup, surgical approach, and postoperative outcomes. The diagnosis was established through the use of CT and ureteroscopy, leading to the decision for radical laparoscopic nephroureterectomy. Additionally, a comprehensive literature review was conducted to discuss the diagnostic challenges and management options for primary ureteral CIS.

Abstract
Kidney-sparing surgery (KSS) for upper urinary tract urothelial carcinoma (UTUC) is a promising alternative to radical nephroureterectomy, especially for low-risk cases. However, due to the established risk of ipsilateral UTUC recurrence caused by the implantation of floating neoplastic cells after endoscopic resection, adjuvant endocavitary (endoureteral) instillations have been proposed. Instillation therapy may be also used as primary treatment for UTUC. The two most studied drugs that have been evaluated in both the adjuvant and primary setting of endocavitary instillation are mitomycin C and Bacillus Calmette-Guerin. The current paper provides an overview of the endocavitary treatments for UTUC, focusing on methods of administration, novel formulations, oncologic outcomes (in terms of endocavitary recurrence and progression), as well as on complications. In particular, the role of UGN-101 as a primary chemoablative treatment of primary noninvasive, endoscopically unresectable, low-grade, UTUC has been analysed. The drug achieved a complete response rate of 58% after the induction cycle, with a durable response independently of the maintenance cycle. The cumulative experience on the role of UUT instillation therapy appears encouraging; however, no definitive conclusions can be drawn about its therapeutic benefit. Given the current state of the art, any decision to administer adjuvant endoureteral therapy for UTUC should be carefully weighed against the potential adverse events. Nevertheless, newer investigations that improve visualization during ureteroscopy, genomic characterization, novel drugs and innovative strategies of improved drug delivery are under evaluation. The landscape of KSS for the treatment of the UTUC is evolving and seems promising.

Abstract
BACKGROUND Radical nephroureterectomy (RNU) represents the gold standard treatment for upper tract urothelial carcinoma (UTUC); however, attempts have been made to treat upper urinary tract CIS (UT-CIS) conservatively. The aim of this study was to compare the outcome of patients with primary UT-CIS treated in our center by means of RNU vs. bacillus Calmette-Guérin (BCG) instillations. METHODS This retrospective study included patients with diagnosis of primary UT-CIS between 1990 and 2018. All patients had histological confirmation of UT-CIS in the absence of other concomitant UTUC. Histological confirmation was obtained by ureteroscopy with multiple biopsies. Patients were treated with BCG instillations, RNU or distal ureterectomy. Clinicopathological features and outcomes were compared between RNU and BCG groups. RESULTS A total of 28 patients and 29 renal units (RUs) were included. Sixteen (57.1%) patients (17 RUs) received BCG. BCG was administered via nephrostomy tube in 4 patients, with a single-J ureteral stent in 5, and using a Double-J stent in 7. Complete response and persistence or recurrence were detected in ten (58.8%) and seven (41.2%) RUs treated with BCG, respectively. Eight (27.6%) RUs underwent RNU, and 4 (13.8%) Rus distal ureterectomy. No differences were found in recurrence-free survival (p=0.841) and cancer-specific survival (p=0.77) between the RNU and BCG groups. CONCLUSIONS Although RNU remains the gold standard treatment for UT-CIS, our results confirm that BCG instillations are also effective. Histological confirmation of UT-CIS is mandatory before any treatment.

Abstract
Upper urinary tract urothelial carcinoma (UTUC) represents a minor subgroup of malignancies arising in the urothelium of the renal pelvis or ureter. The estimated annual incidence is around 2 cases per 100,000 people, with a mean age at diagnosis of 73 years. UTUC is more frequently diagnosed in an invasive or metastatic stage. However, even though the incidence of UTUC is not high, UTUC tends to be aggressive and rapidly progressing with a poor prognosis in some patients. A significant challenge in UTUC is ensuring accurate and timely diagnosis, which is complicated by the non-specific nature of symptoms seen at the onset of disease. Moreover, there is a lack of biomarkers capable of identifying the early presence of the malignancy and guide-tailored medical treatment. However, the growing understanding of the molecular biology underlying UTUC has led to the discovery of promising new biomarkers. Among these biomarkers, there is a class of small non-coding RNA biomarkers known as microRNAs (miRNAs) that are particularly promising. In this review, we will analyze the main characteristics of UTUC and focus on microRNAs as possible novel tools that could enter clinical practice in order to optimize the current diagnostic and prognostic algorithm.

Abstract
Purpose of Review Upper tract urothelial carcinoma (UTUC) is uncommon accounting for less than 10% of all urothelial tumours. Ureteroscopic management (URS) is the first line treatment for low-risk disease and has been increasingly utilised due to technological advances and increasing surgical experience. This review looks at patient outcomes relating to URS, emerging technologies and the role of adjuvant intracavitary therapy in the management of UTUC. Recent Findings URS has firmly established itself in the management algorithm for UTUC, and a good body of evidence supports its use for low-risk disease, wherein oncological outcomes are comparable to traditional nephroureterectomy (RNU). Larger tumours can now be managed using URS with a lower morbidity than radical surgery, though with higher associated local recurrence rate and risk of progression to RNU, and as a result, patient selection and close surveillance remains key. There is limited evidence for adjuvant intracavitary therapy (Mitomycin C or BCG) in UTUC although the development of novel polymers and biodegradable stents may improve drug delivery to the upper urinary tract. Summary URS has a clearly defined role in low-risk UTUC, and its use in larger tumours appears to be appropriate in a selected cohort of patients. The efficacy of adjuvant intracavitary therapy is as of yet undetermined, though developments in delivery techniques are promising. Likewise further developments of laser technology are anticipated to further expand the role of URS.

Abstract
CONTEXT The European Association of Urology (EAU) Guidelines Panel on Upper Urinary Tract Urothelial Carcinoma (UTUC) has prepared updated guidelines to aid clinicians in the current evidence-based management of UTUC and to incorporate recommendations into clinical practice. OBJECTIVE To provide an overview of the EAU guidelines on UTUC as an aid to clinicians. EVIDENCE ACQUISITION The recommendations provided in the current guidelines are based on a thorough review of available UTUC guidelines and articles identified following a systematic search of Medline. Data on urothelial malignancies and UTUC were searched using the following keywords: urinary tract cancer, urothelial carcinomas, upper urinary tract carcinoma, renal pelvis, ureter, bladder cancer, chemotherapy, ureteroscopy, nephroureterectomy, neoplasm, adjuvant treatment, instillation, recurrence, risk factors, and survival. References were weighted by a panel of experts. EVIDENCE SYNTHESIS Owing to the rarity of UTUC, there are insufficient data to provide strong recommendations. The 2017 tumour, node, metastasis (TNM) classification is recommended. Recommendations are given for diagnosis and risk stratification as well as for radical and conservative treatment, and prognostic factors are discussed. A single postoperative dose of intravesical mitomycin after nephroureterectomy reduces the risk of bladder tumour recurrence. Kidney-sparing management should be offered as a primary treatment option to patients with low-risk tumour and two functional kidneys. After radical nephroureterectomy, cisplatin-based chemotherapy is indicated in locally advanced UTUC. CONCLUSIONS These guidelines contain information on the management of individual patients according to a current standardised approach. Urologists should take into account the specific clinical characteristics of each patient when determining the optimal treatment regimen, based on the proposed risk stratification of these tumours. PATIENT SUMMARY Urothelial carcinoma of the upper urinary tract is rare, but because 60% of these tumours are invasive at diagnosis, an appropriate diagnosis is most important. A number of known risk factors exist.

Abstract
Traditionally, urothelial carcinoma of the upper urinary tract was a clear indication for radical nephroureterectomy with bladder cuff excision. It has been shown that in well-selected patients and depending on tumor stage, a kidney-sparing approach can be pursued with good oncological outcome and equivalent to the radical approach. The prevention of local and bladder recurrences is an important factor. Instillation therapies with bacillus Calmette-Guérin and/or mitomycin C have been successfully used to this end. Due to the low incidence of upper tract urothelial cancer and due to the usually retrospective nature of existing literature, however, data is limited. In this article, we provide a review of the indication, technical execution and results of instillation therapies of the upper urinary tract.

Abstract
We aimed to investigate the impact of postoperative weight loss following radical cystectomy (RC) on patients' prognoses. RC and urinary diversion were performed in 512 consecutive patients with muscle-invasive bladder cancer at our hospitals between May 1996 and July 2018. Demographic clinical information, pre- and postoperative serum albumin, hemoglobin, and weight were evaluated retrospectively at 1 month. We also evaluated the association of weight loss with complications and overall survival (OS) as estimated using the Kaplan-Meier method and compared using the log-rank test. Risk factors for poor OS were determined by Inverse Probability of Treatment Weighted (IPTW)-adjusted Cox regression analysis. In 385 patients who met the study search criteria, median postoperative weight loss from baseline at 1 week and 1 month was 1.1 (- 1.8%) and 3.2 (- 5.4%) kg, respectively. Patients with significant weight loss (defined as ≥ 7.5% at 1 month) had higher-grade complications within 1 month and had significantly shorter OS than those with weight loss of < 7.5%. Type of urinary diversion, loss of serum albumin, and loss of hemoglobin were not significantly associated with weight loss. IPTW-adjusted Cox regression analysis showed that such significant weight loss was an independent risk factor for poor OS. Weight loss followed by radical cystectomy was significantly associated with poor prognosis in patients with muscle-invasive bladder cancer.

Abstract
For the management of muscle-invasive bladder cancer or upper tract urothelial carcinoma, the set guidelines recommend regular surveillance after radical cystectomy or radical nephroureterectomy. However, the prognostic benefit of regular oncological surveillance remains controversial in the absence of prospective studies although several retrospective studies with relatively large sample sizes have demonstrated the association between asymptomatic recurrence and better oncological outcomes. Seven out of eight studies reported that patients diagnosed with symptomatic recurrence showed significantly poorer prognosis in comparison to those diagnosed with asymptomatic recurrence. However, potential lead-time and length-time biases prevent the determination of any benefit of regular surveillance. In addition, an optimal surveillance protocol has yet to be established because conventional pathology-based protocols cannot identify the heterogenetic tumor biology of urothelial carcinoma, such as rapid- or slow-growing form of the disease. Several studies suggest that conventional pathology-based surveillance resulted in reduced cost-effectiveness. Recurrence risk-score stratified surveillance protocol including clinical and pathological factors may improve cost-effectiveness. The establishment of optimal risk stratification and surveillance strategies are required to improve the efficacy of regular oncological surveillance. Well-planned prospective studies are necessary to address the prognostic benefit of regular oncological surveillance and shared decision making.
