Phase II trial of intravesical nanoparticle albumin bound paclitaxel for the treatment of nonmuscle invasive urothelial carcinoma of the bladder after bacillus Calmette-Guérin treatment failure.

Purpose: Response rates to current second line intravesical therapies for recurrent nonmuscle invasive bladder cancer range between 10% and 30%. Nanoparticle albumin bound (nab-)paclitaxel has increased solubility and lower toxicity compared to other taxanes. Results of the phase I intravesical trial of this compound demonstrated minimal toxicity during dose escalation.

The role of preoperative prostatic urethral biopsy in clinical decision-making at the time of radical cystectomy.

Introduction: Involvement of the prostatic urethra by bladder cancer directly impacts prognosis, risk of urethral recurrence, and timing of radical cystectomy (RC); it also affects the type of urinary diversion chosen. Both cold cup biopsies and transurethral (TUR) loop biopsies have been used to evaluate the status of the prostatic urethra. We report our 20 year experience with preoperative and intro-operative prostatic urethral biopsies in order to determine relative efficacy and associated treatment implications.

High expression of the PAX3-FKHR oncoprotein is required to promote tumorigenesis of human myoblasts.

PAX3-FKHR is a fusion oncoprotein generated by the 2;13 chromosomal translocation in alveolar rhabdomyosarcoma (ARMS), a cancer associated with the skeletal muscle lineage. Previous studies determined that high-level PAX3-FKHR expression is a consistent feature in ARMS tumors. To investigate the relationship between expression and phenotype in human myogenic cells, PAX3-FKHR was introduced into immortalized human myoblasts to produce a low overall PAX3-FKHR expression level.
