Semantics in active surveillance for men with localized prostate cancer - results of a modified Delphi consensus procedure

Active surveillance (AS) is broadly described as a management option for men with low-risk prostate cancer, but semantic heterogeneity exists in both the literature and in guidelines. To address this issue, a panel of leading prostate cancer specialists in the field of AS participated in a consensus-forming project using a modified Delphi method to reach international consensus on definitions of terms related to this management option. An iterative three-round sequence of online questionnaires designed to address 61 individual items was completed by each panel member. Consensus was considered to be reached if >= 70% of the experts agreed on a definition. To facilitate a common understanding among all experts involved and resolve potential ambiguities, a face-to-face consensus meeting was held between Delphi survey rounds two and three. Convenience sampling was used to construct the panel of experts. In total, 12 experts from Australia, France, Finland, Italy, the Netherlands, Japan, the UK, Canada and the USA participated. By the end of the Delphi process, formal consensus was achieved for 100% (n = 61) of the terms and a glossary was then developed. Agreement between international experts has been reached on relevant terms and subsequent definitions regarding AS for patients with localized prostate cancer. This standard terminology could support multidisciplinary communication, reduce the extent of variations in clinical practice and optimize clinical decision making.Peer reviewe

Oncological and functional outcomes following open radical prostatectomy: how patients may achieve the "trifecta"?

PURPOSE: The desirable outcomes after open radical prostatectomy (RP) for localized prostate cancer (PC) are to: a) achieve disease recurrence free, b) urinary continence (UC), and c) maintain sexual potency (SP). These 3 combined desirable outcomes we called it the "Trifecta". Our aim is to assess the likelihood of achieving the Trifecta, and to analyze the influencing the Trifecta . MATERIALS AND METHODS: A total of 1738 men with localized PC underwent RP from 1992-2007 by a single surgeon. The exclusion criteria for this analysis were: preoperative hormonal or radiation therapy, preoperative urinary incontinence or erectile dysfunction, follow-up less than 24 months or insufficient data. Post-operative Trifecta factors were analyzed, including biochemical recurrence (BR).. We defined: BR as PSA > 0.2 ng/mL, urinary continence as wearing no pads, and sexual potency as having erections sufficient for intercourse with or without a phosphodiesterase-5 inhibitor. RESULTS: A total of 831 patients met the inclusion criteria. The mean age of the entire cohort was 59 years old. The median follow-up was 52 months (mean 60, range 24-202). The BR, UC and SP rates were 18.7%, 94.5%, and 71% respectively. Trifecta was achieved in 64% at 2 year follow-up, and 61% at 5 year follow-up. Multivariate analysis revealed age at time of surgery, pathologic Gleason score (PGS), pathologic stage, specimen weight, and nerve sparing (NS) were independent factors. CONCLUSIONS: Age at time of surgery, pathologic GS, pathologic stage, specimen weight and NS were independent predictors to achieve the Trifecta following radical prostatectomy. This information may help patients counseling undergoing radical prostatectomy for localized prostate cancer

Ureteral stents placed at the time of urinary diversion decreases postoperative morbidity

OBJECTIVE: To determine the impact of stenting ureteroenteric anastomoses on postoperative stricture rate and gastrointestinal recovery in continent and noncontinent urinary diversions (UDs). Patients and Methods: We retrospectively reviewed the clinical and pathologic data on 192 consecutive patients who underwent a radical cystectomy and UD. Patients received either a continent or noncontinent UD with or without stent placement through the ureteroenteric anastomoses. Stricture rate, gastrointestinal recovery, length of hospital stay, and stricture characteristics were analyzed. Study endpoints were compared between four groups – stented and nonstented continent and stented and nonstented noncontinent UDs. RESULTS: 36% of patients were stented and 64% were nonstented at the time of UD. Total ureteral stricture rate was 9.9%. There was no statistically significant difference in stricture rate (p = 0.11) or length of hospital stay (p = 0.081) in stented compared to nonstented patients. There was a significantly (p = 0.014) greater rate of ileus in patients who were nonstented in both continent and noncontinent UDs. CONCLUSION: Stenting of ureteroenteric anastomoses in both continent and noncontinent UD has no effect on postoperative stricture rate, but is associated with lower rates of postoperative ileus

Role of Active Surveillance for Localized Small Renal Masses

Context: Stage migration of organ-confined renal masses is occurring as a result of incidental diagnosis, especially in the elderly. Active surveillance (AS) is gaining clinical traction as a treatment alternative to surgery and focal therapy. Objective: To assess contemporary data and evaluate AS risk trade-offs in the treatment of organ-confined kidney cancer. Evidence acquisition: A comprehensive search of the Embase, Medline and Cochrane databases was carried out. A systematic review of the role of AS for organ-confined renal masses was performed. A total of 28 studies were included in the systematic review. Evidence synthesis: The median linear tumor growth rate for clinically localized renal masses (CLRMs) was 0.37 cm/yr (interquartile range 0.15\u20130.7), with 0.22 cm/yr in the cT1a subgroup and 0.45 cm/yr in the cT1b\u2013\u20132 subgroup. The metastatic progression rate was 1\u20136% and was similar for cT1a (1\u20136%) and cT1b (0\u20135%); other-cause mortality for patients with CLRMs was 0\u201345% (1\u201325% for cT1a vs 11\u201313% for cT1b\u20132); cancer-specific mortality ranged between 0% and 18%. According to the 2011 Oxford scale, AS as a treatment option for CLRMs remains supported by level 3 evidence. Conclusions: Although no randomized clinical data are available, current data support oncologic safety for AS in the management of CLRMs, particularly for small renal masses and among elderly and/or comorbid patients. Patient summary: In this review we looked at the outcomes for patients with small kidney masses managed with surveillance. We found that surveillance is a safe initial option for tumors of less than 2 cm, especially in elderly and sick patients. Active surveillance for clinically localized renal masses is a safe initial option, especially for masses of <2 cm in elderly and sick patients. Further investigation to establish active surveillance protocols and follow-up are still missing. Prospective nonrandomized registry collection of data for patients with small renal masses is ongoing
