Urothelial carcinoma on a ureterocele is extremely rare in the literature, and few case reports have been reported. There are no guidelines for diagnosis and management, and current practice is extrapolated from bladder and upper urothelial tract carcinoma. We present a case from a 61-year-old man with urothelial carcinoma on a ureterocele treated with ureterocele resection, distal urethrectomy, and reimplantation on the bladder. We also review the literature concerning diagnostic approaches and management.

Ureteral papillary carcinoma is a rare subtype of urothelial carcinoma, ranking fourth among cancers following prostate (or breast) cancer, lung cancer, and colorectal cancer. Although previous studies have documented bone metastases mainly in the pelvis, spine, ribs, and femur, this case report presents the first recorded instance of metastasis occurring in the acromioclavicular joint. A 62-year-old woman with a history of left flank pain and macroscopic hematuria underwent a left nephroureterectomy, which revealed ureteral papillary carcinoma.

Purpose Of Review: Antibody-drug conjugates (ADCs) are quickly becoming frontline standard of care in many tumor types, including urothelial carcinoma. This review summarizes recent clinical investigations into the use of ADCs targeting nectin-4, trophoblast cell surface antigen-2 (Trop-2), human epidermal growth factor receptor 2 (HER-2), and other antigens in urothelial carcinoma.
Recent Findings: This review covers efficacy and toxicity data of ADCs alone and in combination with immunotherapy; mechanisms of resistance; and preclinical studies that provide biological basis for clinical approaches.
Background And Objective: Intravesical instillation of chemotherapy (IIC) after radical surgery for upper urinary tract urothelial carcinoma (UTUC) reduces the risk of intravesical recurrence (IVR). However, compliance is low because of possible extravesical leakage after bladder cuff excision. The aim of this study was to evaluate the efficacy of preoperative IIC in reducing the risk of IVR.

Importance: Three similar phase 3 randomized clinical trials have investigated PD-1/PD-L1 (programmed cell death 1 protein/programmed cell death 1 ligand 1) inhibitors in combination with platinum-based chemotherapy vs chemotherapy alone as first-line treatment for advanced urothelial carcinoma (IMvigor130, atezolizumab; KEYNOTE-361, pembrolizumab; and CheckMate901, nivolumab). Only CheckMate901 reported overall survival (OS) benefit for the combination. The reason for these inconsistent results is unclear.
