Current management of non-muscle-invasive bladder cancer.

AIM: Despite standard treatment with transurethral resection (TURBT) and adjuvant therapy, many bladder cancers (BCs) recur and some progress. Based on a review of the literature, we aimed to establish the optimal current approach for the early diagnosis and management of non-muscle-invasive bladder cancer (NMIBC). METHODS: A Medline® search was conducted to identify the published literature relating to early identification and treatment of NMIBC. Particular attention was paid to factors such as quality of TURBT, importance of second TUR, substaging, and carcinoma in situ. In addition, studies on urinary markers, photodynamic diagnosis, predictive clinical and molecular factors for recurrence and progression after BCG, and best management practice were analyzed. RESULTS: Good quality of TUR and the implementation of photodynamic diagnosis in selected cases provide a more accurate diagnosis and reduce the risk of residual tumor in bladder cancer. Although insufficient evidence is available to warrant the use of new urinary molecular markers in isolation, their use in conjunction with cytology and cystoscopy can improve early diagnosis and follow-up. BCG plus maintenance for at least one year remains the standard adjuvant treatment in high-risk BC. Moreover, there is enough evidence to consider the implementation of new specific risk tables for patients treated with BCG. CONCLUSION: In high-risk patients with poor prognostic factors after TUR, early cystectomy should be considered.

High intensity focused ultrasound with Focal-One® device: Prostate-specific antigen impact and morbidity evaluation during the initial experience. / Ultrasonido focalizado de alta intensidad con el dispositivo Focal-One®: impacto sobre el antígeno prostático específico y evaluación de la morbilidad durante la experiencia inicial.

OBJECTIVE: We report our initial experience in the treatment of prostate cancer (PCa) with high-intensity focused ultrasound (HIFU) using the Focal-One® device. MATERIAL AND METHODS: Retrospective review of the prospectively populated database. Between June 2014 to October 2015, 85 patients underwent HIFU (focal/whole-gland) treatment for localized PCa. Preoperative cancer localization was done with multiparametric magnetic resonance imaging (mpMRI) and transperineal mapping biopsies. Treatment was carried out using the Focal-One® device under general anesthesia. Oncological follow-up: PSA measurement and control biopsy with mpMRI according to protocol. Questionnaire-based functional outcome assessment was done. Complications were reported using Clavien classification. RESULTS: The median PSA was 7.79ng/ml (IQR 6.32-9.16), with a median prostate volume of 38cc (IQR: 33-49.75). Focal and whole-gland therapy was performed in 64 and 21 patients respectively. Ten patients received salvage HIFU. Complications were encountered in 15% of cases, all Clavien 2 graded. Mean hospital stay was 1.8 days (0-7) and bladder catheter was removed on day 2 (1-6). Mean percentage reduction of PSA was 54%. Median follow-up was 3 months (IQR: 2-8). Functional outcomes: All patients were continents at 3 months and potency was maintained in 83% of the preoperatively potent. CONCLUSIONS: Focal-One® HIFU treatment appears to be a safe procedure with few complications. Functional outcomes proved no urinary incontinence and sexual function were maintained in 83%.
