Article Synopsis
  • A study reviewed 106 patients with advanced urothelial carcinoma treated with the antibody-drug conjugate enfortumab vedotin (EV) between 2021 and 2023 to evaluate the impact of treatment-related adverse events (trAEs) on survival outcomes.* -
  • The results indicated that 88.7% of patients experienced some form of trAEs, with skin and gastrointestinal issues being the most common, and a landmark analysis suggested that trAEs were linked to longer overall survival, particularly physical trAEs.* -
  • The study concluded that managing trAEs and understanding their prognostic value is important for improving the outcomes of EV therapy in these patients, highlighting that physical trAEs were

Objective: Enfortumab vedotin (EV) was approved for advanced urothelial carcinoma (UC) in 2021 after the EV-301 trial showed its superiority to non-platinum-based chemotherapy as later-line treatment after platinum-based chemotherapy and immune checkpoint inhibitors including pembrolizumab. However, no study has compared EV with rechallenging platinum-based chemotherapy (i.e.

Background: B7-H3 is a member of the B7 family of immune-regulatory ligands and is a costimulatory molecule promoting the T cell response in vitro. We herein investigated the clinical utility of serum soluble B7-H3 (sB7-H3) in patients with non-muscle invasive bladder cancer (NMIBC).

Methods: We analyzed 555 patients in whom NMIBC was diagnosed at Tokyo Metropolitan Tama Medical Center between 2008 and 2013.

Background: B7-H4 is a member of the B7 family of immune-regulatory ligands and is considered to be a negative regulator of the immune response. We investigated the clinical significance of serum soluble B7-H4 in patients with non-metastatic clear cell renal cell carcinoma.

Methods: We analyzed 108 patients in whom non-metastatic clear cell renal cancer was diagnosed at Tokyo Metropolitan Tama Medical Center between 2008 and 2013.

Pazopanib (Votrient®) is an oral small-molecule multi-kinase inhibitor that primarily inhibits vascular endothelial growth factor receptor-1, -2 and -3, platelet endothelial growth factor receptor-α, and -β, and the stem-cell factor receptor c-kit. In preliminary experiments using angiogenesis models with mice and rabbits, pazopanib inhibited angiogenesis caused by combined vascular endothelial growth factor and basic fibroblast growth factor. Although pazopanib was developed as a therapeutic agent against various tumors, it is currently approved in many countries for advanced soft-tissue sarcoma and renal cell carcinoma.

It has previously been demonstrated that the intratumoral generation of the potent androgen dihydrotestosterone (DHT), contributes critically to the progression of prostate cancer and its castration-resistant form, castration-resistant prostate cancer (CRPC). Circulating testosterone is converted into DHT by 5α-reductase (SRD5A). Dutasteride is a dual inhibitor of type I and II SRD5A.

We report a 59-year-old male patient with metastatic small cell carcinoma of the bladder treated with systemic chemotherapy including an amrubicin. The patient was referred to our hospital complaining of macrohematuria. A cytoscopy revealed a non-papillary, broad-based tumor extending from the right to the posterior wall of the bladder.

Objective: Our aim was 2-fold: first, to assess the safety of short hydration treatment for urothelial cancer; and second, to assess the resultant quality of life of patients who received the treatment.

Methods: We assessed 61 patients including 31 outpatients and 30 inpatients, who received a combination of gemcitabine and cisplatin chemotherapy with short hydration. The serum creatinine (Cr) level and the estimated glomerular filtration rate were measured to assess renal function using linear mixed model analysis.

Background: To predict the prognosis, we evaluated the significance of the preoperative neutrophil-lymphocyte ratio (NLR) in patients with upper urinary tract urothelial carcinoma (UUTUC).

Patients And Methods: A cohort of 137 patients diagnosed with UUTUC from 1994 to 2008 at Tokyo Metropolitan Tama Medical Center was enrolled in this retrospective study. Log-rank test and Cox proportional hazards regression models were used for univariate and multivariate analyses.
