Narrative review-focal therapy: are we ready to change the prostate cancer treatment paradigm?

Background and Objective: Prostate cancer (PCa) has seen improved detection methods with a subsequent rise in disease prevalence, making novel prostate cancer treatment options an exciting yet controversial topic. Current treatment modalities encompass traditional approaches, namely surgery (radical prostatectomy) and radiation therapy. While heralded as a standard of care, these modalities may come with significant risk profiles, primarily sexual (erectile dysfunction) and urinary incontinence. Advances in technology and imaging, specifically multi-parametric MRI, have afforded great leaps in targeted focal therapy as a primary treatment option for localized PCa. This review identifies and highlights published data for novel and emerging PCa focal therapy (FT) modalities. Methods: Our study identified and reviewed the current literature for relevant investigations related to primary FT modalities as they apply to the treatment of prostate cancer. After an internal review, relevant studies (published in English, between 2000-April 2022) were included for analysis and summarization. Key Content and Findings: We provide a concise review of several novel focal therapy modalities that offer realistic potential for primary treatment of localized prostate cancer. Our narrative includes studies that primarily include their respective results, specifically focusing on those that reported both oncologic and quality-of-life outcomes after focal therapy. While still in its cumulative infancy, we discuss the current limitations, future directions, and advancements that hopefully push focal therapy into the limelight. Conclusions: While many of the mentioned focal therapies for PCa have shown promising pathologic and quality of life outcomes, further clinical evidence is required to change overall management guidelines and recommendations. The advantages of FT in avoiding sexual and urinary side-effects of radical surgery or radiation are apparent; however, it is necessary to recognize the need for further long-term evidence that is durable over time and comparable to current gold-standard treatment options.

Alternatives to whole gland treatment for localized prostate cancer: a review of novel focal therapies.

PURPOSE OF REVIEW: The mainstays of the management of clinically localized prostate cancer have historically rested upon active surveillance, radiation therapy, or radical prostatectomy. Although both radiation and surgical treatment of localized prostate cancer can achieve excellent oncologic outcomes, the subsequent potential adverse effects of urinary stress incontinence and erectile dysfunction are unappealing to patients. This has led to investigational studies centered upon focal treatment of the cancerous lesion, with the aim to improve quality-of-life outcomes. In this review, we describe numerous novel modalities, including nanoparticle ablation and irreversible electroporation, which are being utilized for the focal treatment of clinically localized prostate cancer. RECENT FINDINGS: Although many of these novel therapies are in their investigational infancy, several have revealed very promising results both in their post-treatment pathologic outcomes as well as objective quality-of-life measures. SUMMARY: Initial data regarding novel focal therapy for prostate cancer treatment show promising short-term outcomes in regards to oncologic and quality-of-life assessments. Further investigational studies are needed to determine inclusion criteria for the selection of optimal candidates.

Utility of Frailty Assessment in Urologic Stone Surgery: A Review of the Literature.

Introduction and Objective: As life expectancy continues to rise, the prevalence of frailty is also increasing. The idea of frailty and its effect on the operative patient has been previously studied, but not regularly incorporated into routine practice. We present a review on frailty metrics in the literature, validated assessment methods, and simplified screening tools to better predict and optimize patient outcomes. Methods: An online PubMed search was conducted by three authors (T.A., T.G.R.B., M.M.) for overall frailty, frailty assessment, and preoperative risk assessment. Only English publications were included in the analysis. Full-text analysis was then conducted by all three authors to validate the data. Results: An abundance of literature was found on frailty. Even though some methods are validated as extremely effective for assessing frailty, they may be time-consuming and require a specialist. Various quick screening methods are also presented, many already validated, and should be utilized by urologists more regularly. Conclusions: Multiple studies demonstrate the relationship between frailty and surgical patients' outcome. Many quick, office-based, validated tools to screen for frailty are described, and should be incorporated into our practice in appropriate patients. Future research is now focused on the concept of "prehabilitation" to improve patient frailty status in the preoperative setting, and consequently operative outcomes.
