RESUMO
BACKGROUND: Ureteral cancer is a rare cancer. This study aimed to provide an up-to-date and comprehensive analysis on the global trends of ureteral cancer incidence and its association with lifestyle and metabolic risk factors. METHODS: The incidence of ureteral cancer was estimated from the Cancer Incidence in Five Continents Plus and Global Cancer Observatory databases. We analyzed the (1) global incidence of ureteral cancer by region, country, sex, and age group by age-standardized rates (ASR); (2) associated risk factors on a population level by univariable linear regression with logarithm transformation; and (3) incidence trend of ureteral cancer by sex and age group in different countries by Average Annual Percentage Change (AAPC). RESULTS: The global age-standardized rate of ureteral cancer incidence in 2022 was 22.3 per 10,000,000 people. Regions with higher human development index (HDI), such as Europe, Northern America, and East Asia, were found to have a higher incidence of ureteral cancer. Higher HDI and gross domestic product (GDP) and a higher prevalence of smoking, alcohol drinking, physical inactivity, unhealthy dietary, obesity, hypertension, diabetes, and lipid disorder were associated with higher incidence of ureteral cancer. An overall increasing trend of ureteral cancer incidence was observed for the past decade, especially among the female population. CONCLUSIONS: Although ureteral cancer was relatively rare, the number of cases reported was rising over the world. The rising trends among females were more evident compared with the other subgroups, especially in European countries. Further studies could be conducted to examine the reasons behind these epidemiological changes and confirm the relationship with the risk factors identified.

OBJECTIVE: To evaluate the classification and prognostic effects of a 2 cm tumor size in patients with ureteral cancer (UC) undergoing segmental ureterectomy (SU). PATIENTS AND METHODS: A total of 75 patients with UC who underwent SU in our hospital between April 2013 and April 2023 were included in this study. The study population was grouped based on tumor size, which was defined as the maximum diameter of the pathological specimens, resulting in 30 patients (40.0%) with tumor size <2 cm and 45 patients (60.0%) with tumor size ≥2 cm. The clinicopathological variables, perioperative parameters, and oncological outcomes were compared between the 2 groups. The endpoints were recurrence-free survival (RFS), and cancer-specific survival (CSS). RESULTS: A tumor ≥2 cm was related to a higher positive rate of urine exfoliative cytology (Pâ¯=â¯0.049) and fewer preoperative ureteroscopies (Pâ¯=â¯0.033) than tumors <2 cm. After a follow-up of 6.3 to 128.7 months (median 40.2 months), 23 cases (30.7%) experienced recurrence and 11 patients (14.7%) succumbed to UC in the end. Compared to those with tumor size <2 cm, patients with tumor size ≥2 cm experienced more urothelial recurrence (Pâ¯=â¯0.032). Kaplan-Meier analysis demonstrated that patients with tumor size ≥2 cm displayed inferior urothelial RFS than those with tumor size <2 cm (Pâ¯=â¯0.026). Multivariate Cox analysis identified tumor size ≥2 cm, and pathological stage ≥T2 were significant prognostic factors of poor urothelial RFS (all P < 0.05). CONCLUSION: Tumor size ≥2 cm was associated with a high rate of urothelial recurrence and served as an independent prognostic factor of adverse urothelial RFS in SU-treated patients with UC. Patients are advised to select surgical treatments for UC following the EAU guidelines.
RESUMO
Prostate cancer (PCa) ranks as the second most common cancer in Japanese males, while bladder cancer (BC) holds the tenth spot. Among double urological cancers, the incidence of synchronous or metachronous BC and PCa is the highest. Reports on upper urinary tract (UUT) urothelial cancer (UC) in PCa patients are limited. Here, we present three cases of metachronous PCa and BC, with subsequent diagnosis of ureteral and renal pelvic cancer during the course of the disease. In the follow-up of patients with urological cancers, it is important to be aware not only of the progression of the initial cancer but also the potential development of a second cancer.
RESUMO
OBJECTIVE: To date, there have been few studies examining the prognostic implications of histological subtypes in ureteral cancer. And chemotherapy plays a crucial role in the treatment of ureteral cancer, while many factors influence the efficacy of chemotherapy. This study aimed to utilize the Surveillance, Epidemiology and End Results database to assess the impact of histological type on ureteral cancer prognostic outcomes and discovered how histological type and T-stage influence the efficacy of chemotherapy. METHODS: Based on Surveillance, Epidemiology, and End Results Program, we reviewed 8915 records of patients with primary ureteral cancer from 18 centers between 2000 and 2018. We focused on the overall survival and cancer-specific survival of the records and used KaplanâMeier method to calculate survival curves. RESULTS: In the comparison of prognostic outcomes, atypical subtypes exhibited a less favorable prognosis compared to typical ureteral carcinoma. Notably, patients diagnosed with papillary urothelial carcinoma demonstrated the most favorable overall survival (p = 0.005). Statistically significant benefits were observed in the prognosis of patients with non-papillary urothelial carcinoma who received chemotherapy (HR = 0.860, 95% CI 0.764-0.966, p = 0.011), while chemotherapy did not yield a statistically significant effect on the prognosis of patients with papillary urothelial carcinoma (HR = 1.055, 95% CI 0.906-1.228, p = 0.493). Chemotherapy had an adverse impact on the prognosis of patients with T1 ureteral cancer (HR = 1.235, 95% CI 1.016-1.502, p = 0.034), whereas it exhibited a positive prognostic effect for T3/T4 cases (HR = 0.739, 95% CI 0.654-0.835, p < 0.001). CONCLUSIONS: Histological type affects the prognosis of ureteral cancer. And evaluation of cancer histological type and T stage in ureteral cancer patients prior to chemotherapy is mandatory.

PURPOSE: Although kidney-sparing surgery (KSS) is a nonminor option for low-risk upper urinary tract urothelial cancer (UTUC), its oncological benefits in high-risk UTUC remain unclear when compared to radical nephroureterectomy (RNU). This study aimed to compare the oncological outcomes of RNU and KSS in patients with UTUC. METHODS: We searched the SEER database for patients treated for primary non-metastatic UTUC with either RNU or a kidney-sparing approach (segmental ureterectomy (SU) or local tumor excision (LTE)) between 2004 and 2018. RESULTS: The study included 6,659 patients with primary non-metastatic UTUC treated with surgery; 2,888 (43.4%) and 3,771 (56.6%) patients presented with ureteral and renal pelvicalyceal tumors, respectively. Finally, 5,479 (82.3%) patients underwent RNU, 799 (12.0%) were treated with SU, and 381 (5.7%) patients received LTE. For confounder control, propensity score matching (PSM) of patients treated with SU and RNU was performed to adjust for T stage, grade, age, gender, tumor size, and lymphadenectomy performance. PSM analysis included 694 patients treated with RNU and 694 individuals who underwent SU. In multivariable Cox regression and Kaplan-Meier analyses, we found no difference in either CSS or OS between RNU and SU, even in the subgroup of high-grade and/or muscle-invasive UTUC including pT3-T4 tumors (all p > 0.05). CONCLUSION: In this population-based study, SU provides equivalent CSS and OS compared to RNU, even in high-risk and locally advanced ureteral cancer. Due to the unavoidable risk of selection bias, further prospective studies are expected to overcome the limitations of this study and support the wider implementation of KSS.

OBJECTIVE: UGN-101 has been approved for the chemoablation of low-grade upper tract urothelial cancer (UTUC) involving the renal pelvis and calyces. Herein is the first reported cohort of patients with ureteral tumors treated with UGN-101. PATIENTS AND METHODS: We performed a retrospective review of patients treated with UGN-101 for UTUC at 15 high-volume academic and community centers focusing on outcomes of patients treated for ureteral disease. Patients received UGN-101 with either adjuvant or chemo-ablative intent. Response rates are reported for patients receiving chemo-ablative intent. Adverse outcomes were characterized with a focus on the rate of ureteral stenosis. RESULTS: In a cohort of 132 patients and 136 renal units, 47 cases had tumor involvement of the ureter, with 12 cases of ureteral tumor only (8.8%) and 35 cases of ureteral plus renal pelvic tumors (25.7%). Of the 23 patients with ureteral involvement who received UGN-101 induction with chemo-ablative intent, the complete response was 47.8%, which did not differ significantly from outcomes in patients without ureteral involvement. Fourteen patients (37.8%) with ureteral tumors had significant ureteral stenosis at first post-treatment evaluation, however, when excluding those with pre-existing hydronephrosis or ureteral stenosis, only 5.4% of patients developed new clinically significant stenosis. CONCLUSIONS: UGN-101 appears to be safe and may have similar efficacy in treating low-grade urothelial carcinoma of the ureter as compared to renal pelvic tumors.

An 82-year-old man was diagnosed with synchronous non-muscle-invasive bladder cancer and left lower ureteral carcinoma. He underwent transurethral resection of the bladder tumor, followed by total left nephroureterectomy after preoperative chemotherapy with four courses of gemcitabine and carboplatin. Histopathological findings showed positive-margin carcinoma in situ. In addition, since recurrence of non-muscle-invasive bladder cancer was observed in the bladder, Bacille Calmette-Guérin intravesical infusion therapy was performed, but the cancer persisted due to treatment resistance. After that, pembrolizumab therapy was performed, and complete remission was achieved.
RESUMO
Introduction: Robot-assisted surgery is spreading across surgical specialities as a less invasive alternative to conventional laparoscopic and open surgery. Case presentation: In this report, robot-assisted total laparoscopic hysterectomy and robot-assisted nephroureterectomy were performed simultaneously for a 69-year-old Japanese female with giant cervical polyp and ureteral cancer. All specimens could be removed from the vagina. The operative time was 379 min, the estimated intraoperative blood loss was 29 mL, and the patient was discharged on the sixth postoperative day without complications. Conclusion: We reported our experience with simultaneous robot-assisted nephroureterectomy and robot-assisted total laparoscopic hysterectomy. To our knowledge, this is the first report of simultaneous robot-assisted nephroureterectomy and robot-assisted total laparoscopic hysterectomy surgery.
RESUMO
AIM: This study aimed to report initial results of hypofractionated carbon-ion radiotherapy (C-ion RT) for inoperable upper tract ureteral cancer. METHODS: Retrospective chart review was performed for five consecutive patients with medically inoperable ureter cancer that was treated with radical C-ion RT between December 2013 and December 2014. The median age of the patients was 80 years (range, 68-84 years). The reasons for inoperability were advanced age, post-contralateral nephrectomy, alcoholic cirrhosis, both advanced age and contralateral renal function degeneracy, and pneumonia. The median size of tumor was 2.8 cm (range, 2.2-4.0 cm). Diagnostic imaging did not identify lymph node metastases or distant metastases in any case. All patients underwent C-ion RT (52.8 Gy relative biological effectiveness; 12 fractions in 3 weeks). The clinical target volume encompassed the growth tumor volume with a 5-mm margin bilaterally; there was a 40-mm margin craniocaudally but the clinical target volume did not encompass the whole ureter. RESULTS: Within a median follow-up time of 32.9 months (range, 24-36 months), two patients died and three remained alive. Neither local recurrence nor regional lymph node metastases were observed. Secondary bladder tumor was observed in four patients, and one patient had a liver metastasis. Grade 1 hematuria was observed in two patients, and Grade 3 pyelonephritis was observed in one patient as acute toxicity. Ureteral obstruction was observed in two patients. CONCLUSION: C-ion RT might be a useful treatment option for inoperable ureter cancer.
RESUMO
PURPOSE: The purpose of this guideline is to provide a useful reference on the effective evidence-based diagnoses and management of non-metastatic upper tract urothelial carcinoma (UTUC). MATERIALS/METHODS: The Pacific Northwest Evidence-based Practice Center of Oregon Health & Science University (OHSU) team conducted searches in Ovid MEDLINE (1946 to March 3rd, 2022), Cochrane Central Register of Controlled Trials (through January 2022), and Cochrane Database of Systematic Reviews (through January 2022). The searches were updated August 2022. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions (Table 1).[Table: see text]Results:This Guideline provides updated, evidence-based recommendations regarding diagnosis and management of non-metastatic UTUC including risk stratification, surveillance and survivorship. Treatments discussed include kidney sparing management, surgical management, lymph node dissection (LND), neoadjuvant/adjuvant chemotherapy and immunotherapy. CONCLUSION: This standardized guideline seeks to improve clinicians' ability to evaluate and treat patients with UTUC based on available evidence. Future studies will be essential to further support these statements for improving patient care. Updates will occur as the knowledge regarding disease biology, clinical behavior and new therapeutic options develop.

PURPOSE: The high incidence of upper urinary tract urothelial carcinoma (UTUC) in Taiwan is largely due to exposure to aristolochic acid (AA), a principal component of Aristolochia-based herbal medicines. Here we systematically review the molecular epidemiology, clinical presentation and biomarkers associated with AA-induced UTUC. METHODS: This is a narrative review. Medline, Embase, and Web of Science were searched from inception to December 31, 2021. Studies evaluating the association, detection, and clinical characteristics of AA and UTUC were included. RESULTS: A nationwide database revealed 39% of the Taiwanese population had been exposed to AA-containing herbs between 1997 and 2003. Epidemiological reports revealed AA posed a significantly higher hazard for renal failure and UTUC in herbalists and the general population who ingested AA-containing herbs. The presence of aristolactam-DNA adducts and a distinctive signature mutation, A:T to T:A transversions, located predominantly on the non-transcribed DNA strand, with a strong preference for deoxyadenosine in a consensus sequence (CAG), was observed in many UTUC patients. Clinically, AA-related UTUC patients were characterized by a younger age, female gender, impaired renal function and recurrence of contralateral UTUC. To date, there are no preventive measures, except prophylactic nephrectomy, for subjects at risk of AA nephropathy or AA-related UTUC. CONCLUSION: AA exposure via Aristolochia-based herbal medicines is a problem throughout Taiwan, resulting in a high incidence of UTUC. Aristolactam-DNA adducts and a distinctive signature mutation, A:T to T:A transversions, can be used as biomarkers to identify AA-related UTUC. AA-related UTUC is associated with a high recurrence rate of contralateral UTUC.

In the early stages of immunocheckpoint inhibitor administration, we should be aware of rapid cancer progression, known as hyperprogressive disease, in real-world clinical practice. We report a case of a 73-year-old man who presented with right abdominal pain and was diagnosed with advanced right ureteral cancer involving the duodenum. He received four cycles of chemotherapy with gemcitabine plus cisplatin, followed by maintenance with avermab. After two cycles of avermab within a month, his primary cancer dramatically progressed and he died. This is the first report of a case in which unresectable ureteral cancer caused hyperprogressive disease after avelumab maintenance therapy.
RESUMO
Upper tract urothelial carcinoma (UTUC) has traditionally been managed with radical nephroureterectomy, and while this approach remains the gold standard for high-risk disease, endoscopic, kidney-sparing management has increasingly been adopted for low-risk disease as it preserves kidney function without compromising oncologic outcomes. Ureteroscopy and percutaneous renal access not only provide diagnoses by tumor visualization and biopsy, but also enable treatment with electrocautery or laser ablation. Several modalities exist for laser ablative treatments including thulium:YAG, neodymium:YAG, holmium:YAG, and combinations of the preceding. Furthermore, due to high recurrence rates after endoscopic management, adjuvant intracavitary instillation of various agents such as mitomycin C and bacillus Calmette-Guerin have been used given benefits seen in non-muscle invasive urothelial bladder cancer. Other formulations also being studied include gemcitabine, anthracyclines, and immunotherapies. More recently, Jelmyto, a mitomycin reverse thermal gel, has been developed to allow for adequate drug delivery time and potency since urine flow could otherwise dilute and washout topical therapy. In this article, the authors review techniques, indications, best practices, and areas of current investigation in endoscopic management and adjuvant topical therapy for UTUC.
RESUMO
An 80 year old Japanese man with bilateral ureteral cancer underwent laparoscopic bilateral nephroureterectomy and lymph-node dissection. The pathological stage of the left and right ureteral tumors was pT3pN0M0. He received two courses of adjuvant gemcitabine and cisplatin chemotherapy while undergoing hemodialysis. The standard dose of gemcitabine and 50% of the standard dose of cisplatin were administered on the same day. Hemodialysis was started 6 h after gemcitabine administration and 1 h after cisplatin administration. The side effects were evaluated according to the Common Terminology Criteria for Adverse Events v4.0. In the first course, Grade 4 side effects including leukopenia, neutropenia, and thrombocytopenia were observed. He was treated with granulocyte colony-stimulating factor and platelet transfusion. Because the second course was administered without reducing the doses, granulocyte colony-stimulating factor was administered prophylactically, and Grade 4 side effects were reduced to Grade 3. Gemcitabine plus cisplatin chemotherapy can be administered safely in a patient with advanced ureteral cancer undergoing hemodialysis by adequately managing adverse events.
RESUMO
Recently, the use of immune checkpoint inhibitors (ICIs) with or without chemotherapeutic agents has been increasing in the treatment for advanced cancer. Here, we report the occurrence of liver failure after the use of pembrolizumab in an 82-year-old woman with metastatic liver disease derived from right advanced renal pelvis, ureteral cancer, and bladder cancer. She was successfully treated with 0.6 mg/kg daily prednisolone. In patients treated with ICIs, ICI-induced hepatitis is occasionally observed. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment. This is a first report of pembrolizumab-induced liver failure in elder patient with age over 80 years. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment.
RESUMO
INTRODUCTION: Lymphoceles are sometimes formed after pelvic lymph node dissection. However, recurrence at lymphoceles has not been reported previously. Here, we report a case of rapid prognosis of the recurrence at a lymphocele after nephroureterectomy. CASE PRESENTATION: A 78-year-old man underwent retroperitoneoscopic radical nephroureterectomy with pelvic lymphadenectomy for left ureteral urothelial carcinoma. The histopathological diagnosis was high-grade invasive urothelial carcinoma with squamous differentiation. Follow-up computed tomography at 3 months postoperatively showed a lymphocele with a small solid component, in the left pelvic region. At 7 months postoperatively, he presented with severe fatigue, and computed tomography showed a solid tumor had replaced the lymphocele. Computed tomography-guided biopsy was performed and histopathological diagnosis was squamous cell carcinoma. CONCLUSION: This report provides support for possible recurrence at the lymphocele after nephroureterectomy. If lymphocele occurs after surgery for malignant disease, it is recommended to follow up with the possibility of recurrence in the lymphatic cysts in mind.
RESUMO
BACKGROUND: Pulmonary lymphangitic carcinomatosis (PLC) is a metastatic lung disease of malignant tumors that spread through pulmonary lymphatic vessels. Although prompt diagnosis and specific treatment of PLC are required due to the poor prognosis associated with this disease, it is often challenging to determine the primary cancer site. CASE PRESENTATION: A 67-year-old Japanese woman presented to our hospital with a 10-day history of cough and dyspnea on exertion. Chest radiography and computed tomography (CT) revealed diffuse nodular opacities with interlobular septal thickening. Both bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) revealed carcinoma cells with unknown origin. Contrast-enhanced CT depicted a mass in the right ureter with hydronephrosis, and retrograde urography showed a narrowing of the right ureter. Urine cytology from her right ureter via ureteral catheter also revealed atypical cells, highly suggestive of malignancy. Immunohistochemical examination of lung specimens via TBLB showed results consistent with lung metastasis of ureteral cancer. Therefore, we arrived at a diagnosis of PLC secondary to ureteral cancer. CONCLUSIONS: This case encouraged multidisciplinary discussion and a whole-body examination, including TBLB with immunohistochemistry, to determine the origin of PLC.
RESUMO
An overview of epidemiological pattern of upper tract urothelial carcinoma (UTUC), including outcome of UTUC over past decades as well as factors responsible for observed epidemiological changes was performed. Gender and racial disparities influencing incidence of UTUC were reviewed. The incidence of multifocal urothelial carcinoma and relation of UTUC to urothelial carcinoma of bladder were examined.
RESUMO
BACKGROUND: Sarcoidosis is a multisystem inflammatory disorder and can affect any organ; however, ureteric involvement is extremely rare with only four cases reported in the literature to date, all of which were diagnosed with surgical ureteral resection including a nephroureterectomy. This study reports the first case of ureteric sarcoidosis controlled with medical therapy where a differential diagnosis was performed based on the diagnostic clue of hypercalcemia. A definitive diagnosis was established without surgical resection of the ureter. CASE PRESENTATION: A 60-year-old man presented with anorexia and weight loss. Blood tests showed renal dysfunction and hypercalcemia. Computed tomography revealed left hydronephrosis associated with left lower ureteral wall thickening, which showed high signal intensity on diffusion-weighted magnetic resonance imaging. Similarly, we detected a bladder tumor on cystoscopy, and a 2-cm-long stenosis was revealed by retrograde ureterography; therefore, ureteral cancer was suspected. Meanwhile, considering the clinical implication of hypercalcemia, a differential diagnosis of sarcoidosis was established based on elevated levels of sarcoidosis markers. Fluorodeoxyglucose positron emission tomography showed fluorodeoxyglucose accumulation in the left lower ureter, skin, and muscles, suggestive of ureteric sarcoidosis with systemic sarcoid nodules. For a definitive diagnosis, transurethral resection of the bladder tumor and ureteroscopic biopsy were performed. Histopathological examination revealed ureteric sarcoidosis with bladder urothelial carcinoma. Following an oral administration of prednisolone, hypercalcemia instantly resolved, the renal function immediately improved, and the left ureteral lesion showed complete resolution with no recurrence. CONCLUSIONS: In this case, the co-occurrence of ureteral lesion with bladder tumor evoked a diagnosis of ureteral cancer. However, considering a case of ureteral lesion complicated with hypercalcemia, assessment for differential diagnosis was performed based on the calcium metabolism and sarcoidosis markers. In cases of suspected ureteric sarcoidosis from the assessment, pathological evaluation with ureteroscopic biopsy should be performed to avoid nephroureterectomy.

BACKGROUND: Breast metastasis from extra-mammary primary tumors is extremely rare. We recently experienced a rare case of a male breast metastasis of ureteral cancer and will provide a case report. CASE PRESENTATION: A 74-year-old man developed a ureteral cancer and underwent left nephroureterectomy with lymph node dissection. Although enlarged abdominal lymph nodes did not disappear completely after chemoradiotherapy, further extensive therapy was not performed. A mass just below the nipple of his right breast was acknowledged and he visited our department. Histological diagnosis was invasive carcinoma. It was initially diagnosed as a primary breast cancer, and he underwent a mastectomy and a sentinel lymph node biopsy. There was no intraductal lesion and the border of the tumor was clear. It was very similar to that of the previous ureteral cancer. The final diagnosis was breast metastasis of ureteral cancer rather than primary breast cancer. The postoperative course was good, but multiple lung metastases appeared 2 months after surgery. He eventually died of cancerous lymphangiopathy. CONCLUSION: It is important to accurately diagnose primary breast cancer or breast metastasis so as not to cause extra-invasion, but it was considered difficult to make a complete preoperative diagnosis.
