Methylation of tumor suppressor genes in a novel panel predicts clinical outcome in paraffin-embedded bladder tumors.

DNA methylation of tumor suppressor genes (TSGs) represents a frequent and early epigenetic event with potential applications for cancer detection and disease evolution. Our aim was to examine the stratification and prognostic biomarker role of the methylation of a novel panel of TSGs in bladder cancer. The methylation status of 18 TSGs was evaluated in bladder cancer cells (n=14) and paraffin-embedded primary bladder tumors (n=61), using a methylation-specific multiplex ligation-dependent probe amplification assay (MS-MLPA).

[The treatment of urinary incontinence by injectables. Analysis of our series].

Objectives: To determine the efficacy of endoscopical injections for the treatment of stress urinary incontinence (SUI), evaluating its low invasiveness and positive impact on quality of life.

Methods/results: Belween 1997--2003 30 procedures of periurethral injection of various substances for urinary incontinence were performed at our department in women between 47-80 years. All patients were evaluated before surgery, clinically and urodynamically, in accordance to international standardized parameters (filling pressure/flow studies, maximum urethral closure pressure, LPP-leak point pressure).
