Dysgeusia in patients with advanced urothelial carcinoma receiving enfortumab vedotin, platinum-based chemotherapy, or immune check point inhibitors: time-course assessment using chemotherapy-induced taste alteration scale.

A time-course questionnaire survey using the chemotherapy-induced taste alteration scale (CiTAS) was conducted in patients with advanced urothelial carcinoma (UC) treated with systemic chemotherapy and/or immunotherapy. A total of 37 patients receiving systemic therapy with enfortumab vedotin (EV), platinum-based chemotherapy and immune checkpoint inhibitors were included in this study. No significant changes were observed in any of the CiTAS subscales during platinum-based chemotherapy and immune checkpoint inhibitor treatment, while EV therapy induced significant dysgeusia. Among 10 patients treated with EV, dysgeusia was associated with a substantial negative effect on the health-related quality-of-life domains, particularly global health status/QOL (mean ± standard deviation: 52 ± 19 in dysgeusia group vs 89 ± 13 in non-dysgeusia group) and mental component summary (47 ± 5.1 vs 53 ± 2.0). The fatigue symptom score was higher in the dysgeusia group at the post-third cycle of EV (47 ± 16 vs 15 ± 17). Severe dysgeusia can be induced by EV therapy, which is usually not observed in other systemic therapies for advanced UC.

Trisomy 13 with retroiliac ureter diagnosed by assessment for recurrent febrile urinary tract infections.

Introduction: Patients with trisomy 13 have multiple malformations, including urological anomalies, and severe cognitive and psychomotor disabilities. We conducted a ureteroureterostomy for a mid-ureteral stricture due to a retroiliac ureter in a patient with trisomy 13. Case presentation: A 6-month-old girl with trisomy 13 developed a urinary tract infection. Computed tomography for assessing recurrent urinary tract infection revealed a left mid-ureteral stricture due to the retroiliac ureter. At the age of 2, a ureteroureterostomy was performed. Two years after surgery, the urinary tract infection did not recur. Conclusion: Ureteroureterostomy is a safe procedure for children with trisomy 13 and multiple comorbidities. Surgical treatment should be considered for patients with trisomy 13 when agreed upon by the family and comorbidities are well-controlled.

Assessment of diagnostic accuracy for cryptorchidism and risk factors for delayed orchidopexy.

OBJECTIVES: Cryptorchidism (CO) diagnosis by palpation is challenging. Patients with suspected CO are primarily referred to pediatric urologists by general pediatricians and urologists. Currently, surgical treatment for CO is recommended earlier than in previous guidelines. In this study, we evaluated factors that lead to diagnosis discordance and delayed orchidopexy in patients referred with suspected CO in addition to timing of initial screening. METHODS: In total, 731 patients (1052 testes) with suspected CO were included. Risk factors for diagnostic discrepancy in CO diagnosis by pediatric urologists and risk of delayed orchiopexy were evaluated. RESULTS: Herein, 659 (90%) patients were diagnosed during routine public health checkups for infants and young children, and 419 (57%) patients were referred by pediatric practitioners. Of 1052 testes, 374 (36%) were diagnosed with CO by pediatric urologists. In multivariate analysis, risk factors of diagnostic discrepancy for CO diagnosis by pediatric urologists were bilateral testis (odds ratio [OR] = 9.17, p < 0.0001), >6 months old at initial diagnosis (OR = 1.036, p < 0.0001), and pediatric referral (OR = 4.60, p < 0.0001). In total, 296 patients underwent orchiopexy for CO. In multivariate analysis, risk factors for delayed orchiopexy were presence of comorbidities (OR = 3.43, p = 0.003) and >10 months old at referral (OR = 12.62, p < 0.0001). CONCLUSIONS: Pediatric referral is a risk factor for discordant CO diagnostics, and late age at referral brings a risk of delayed orchiopexy. It is necessary to enlighten pediatricians, who are mainly responsible for routine health checkups, in teaching CO diagnostic techniques to ensure early referral.

The Japanese health care system-based cost-effectiveness of photodynamic diagnosis-assisted transurethral resection of bladder tumor for non-muscle invasive bladder cancer.

BACKGROUND: Photodynamic diagnosis-assisted transurethral resection of bladder tumor reduces the risk of intravesical recurrence compared with conventional white light-transurethral resection of bladder tumor. However, the patient burden of costs for photodynamic diagnosis-transurethral resection of bladder tumor is higher than that for white light-transurethral resection of bladder tumor per installment, and the impact of the medical economics of photodynamic diagnosis-transurethral resection of bladder tumor is unclear. Therefore, we evaluated the Japanese health care system-based cost-effectiveness of photodynamic diagnosis-transurethral resection of bladder tumor compared with that of white light-transurethral resection of bladder tumor. METHODS: We conducted a retrospective chart review of 100 patients who underwent initial white light- or photodynamic diagnosis-transurethral resection of bladder tumor for non-muscle invasive bladder cancer from February 2012 to August 2019. Cumulative intravesical recurrences during 1000 post-operative days after the initial transurethral resection of bladder tumor were counted. Furthermore, the cumulative costs were calculated using the Diagnostic Procedure Combination and Per-Diem Payment System unique to Japan. The costs/year/person calculated using the person-year method was compared between the white light- and photodynamic diagnosis-transurethral resection of bladder tumor. RESULTS: Among the 100 patients, 40 (40%) and 60 (60%) underwent the initial white light- and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. The cumulative incidence of bladder recurrence requiring hospitalization and transurethral resection of bladder tumor was 20 and 5% for the white light-transurethral resection of bladder tumor and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. The costs for hospitalization and surgical procedures per white light- or photodynamic diagnosis-transurethral resection of bladder tumor were 348 228 and 481 820 Japanese yen, respectively. The cost/year/person by the person-year method was 8073 and 8557 Japanese yen for the white light- and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. CONCLUSIONS: The cost/year/person for hospitalization and surgical procedures was slightly different between the white light- and photodynamic diagnosis-transurethral resection of bladder tumor. Furthermore, photodynamic diagnosis-transurethral resection of bladder tumor can reduce intravesical recurrence and is more cost-effective than white light-transurethral resection of bladder tumor.
