Comparative Evaluation of Bladder-specific Health-related Quality of Life Instruments for Bladder Cancer.

Objective: To compare 2 bladder cancer-specific health-related quality of life instruments (HRQOL) in the same patient population. Previous HRQOL studies in cystectomy patients have yielded conflicting results. Using a cross-sectional study design, we examined the only 2 validated bladder cancer-specific (HRQOL) measures.

Progression of epididymal maldevelopment into hamartoma-like neoplasia in VHL disease.

Inactivation of the von Hippel-Lindau (VHL) gene and activation of the hypoxia-inducible factor (HIF) in susceptible cells precedes formation of tumorlets and frank tumor in the epididymis of male VHL patients. We performed detailed histologic and molecular pathologic analysis of tumor-free epididymal tissues from VHL patients to obtain further insight into early epididymal tumorigenesis. Four epididymides from two VHL patients were serially sectioned to allow for three-dimensional visualization of morphologic changes.
