Controlled Clinical Trial
Stratification of aggressive prostate cancer from indolent disease-Prospective controlled trial utilizing expression of 11 genes in apparently benign tissue.
The aim of the study was to evaluate the diagnostic power of molecular markers in men with a clinical suspicion of prostate cancer (PCa) using apparently benign areas as targeted by magnetic resonance imaging (MRI). ⋯ Of the 11 studied genes, TDRD1 and TMPRSS2-ERG were able to statistically significantly differentiate men with PCa from men without it as single markers. However, a multivariate analysis using 15 features outperformed each individual marker in identifying aggressive PCa.

Intravesical Bacillus Calmette-Guérin (BCG) remains the standard of care in the treatment of bladder carcinoma in situ and as adjuvant therapy after thorough transurethral resection of high-grade non-muscle-invasive bladder cancer. Despite BCG therapy, in up to 40% of patients it would recur and 60% to 70% of those would fail repeat BCG induction be deemed BCG unresponsive. For such patients, cystectomy remains the preferred treatment option per the American Urological Association and European Association of Urology, though some patients would be medically unfit or refuse radical surgery. ⋯ There are numerous non-BCG intravesical salvage options available, including immunotherapy, single-agent chemotherapy, combination chemotherapy, and device-assisted chemotherapy. In addition, investigation of radiation-based treatment and other novel therapies including checkpoint inhibitors (programmed death-1/programmed death ligand-1), are currently underway. In this review, we examine the current status of alternatives to BCG in salvage therapy for bladder preservation.

To investigate the modified frailty index (mFI) as a preoperative predictor of postoperative complications following radical cystectomy (RC) in patients with bladder cancer. ⋯ Among patients undergoing RC, the mFI can identify those patients at greatest risk for severe complications and mortality. Given that bladder cancer is increasing in prevalence particularly among the elderly, preoperative risk stratification is crucial to inform decision-making about surgical candidacy.
