Prostate focal therapy offers men the opportunity to achieve oncological control while preserving sexual and urinary function. The prerequisites for successful focal therapy are to accurately identify, localize and completely ablate the clinically significant cancer(s) within the prostate. We aim to evaluate the evidence for current and upcoming technologies that could shape the future of prostate cancer focal therapy in the next five years. Areas Covered: Current literature on advances in patient selection using imaging, biopsy and biomarkers, ablation techniques and adjuvant treatments for focal therapy are summarized...

Therapeutic ultrasound approaches including high-intensity focused ultrasound (HIFU) are emerging as popular minimally invasive alternative treatments for localized, low-to-intermediate risk prostate cancer. FDA approval was recently granted for two ultrasound-guided HIFU devices. Clinical trials for devices using MRI guidance are ongoing. The current level of evidence for whole-gland ultrasound ablation suggests that its clinical efficacy and adverse event rates including erectile dysfunction and urinary incontinence are similar to current definitive therapies such as radical prostatectomy and external-beam radiotherapy...

Vascular targeted photodynamic therapy (VTP) with WST11 is a novel non-thermal focal treatment for localized prostate cancer that has shown favorable and early efficacy results in previously published studies. In this work, we investigate the efficiency of automatic dosimetric treatment planning. An action model established in a previous study was used in an image-guided optimization scheme to define the personalized optimal light dose for each patient. The calculated light dose is expressed as the number of optical cylindrical fibers to be used, their positions according to an external insertion grid, and the lengths of their diffuser parts...

INTRODUCTION: Salvage treatment options for recurrent unilateral prostate cancer (PCa) after primary radiation are limited and associated with severe complications and poor quality of life measures. Salvage focal cryotherapy (SFC) has shown success in biochemical recurrence (BCR) free survival. We aim to determine if SFC can delay use of androgen deprivation therapy (ADT) in recurrent PCa with low morbidity. METHODS: A retrospective review of patients who underwent SFC at our institution from 2007 to 2015 was performed...

In patients with metallic hip implants, distortions, and other artifacts relating to the echo-planar imaging acquisition may render prostate diffusion-weighted imaging (DWI) nondiagnostic. Reduced field-of-view (rFOV) acquisition, using parallel transmission and focused excitation, is a novel DWI approach that reduces distortions and improves images quality. This article presents images from both standard and rFOV DWI acquisitions in 2 prostate cancer patients with hip implants, showing the effect of rFOV DWI for improving tumor localization...

CLINICAL PROBLEM: Prostate cancer is one of the most common malignant diseases in older men. As such, screening and early detection are of crucial importance. STANDARD TREATMENT: The standard management of prostate cancer includes radical prostatectomy, radiation therapy, or hormonal therapy. These standard therapies yield excellent oncologic results, but also produce significant side effects. In cases of low-risk prostate cancer, these therapies might result in over-treatment; for this reason, active surveillance has been introduced...

The search for new therapeutics for the treatment of prostate cancer is ongoing with a focus on the balance between the harms and benefits of treatment. New therapies are being constantly developed to offer treatments similar to radical therapies, with limited side effects. Photodynamic therapy (PDT) is a promising strategy in delivering focal treatment in primary as well as post radiotherapy prostate cancer. PDT involves activation of a photosensitizer (PS) by appropriate wavelength of light, generating transient levels of reactive oxygen species (ROS)...

PURPOSE/BACKGROUND: [(18)F]fluoroethylcholine ((18)FECH) has been shown to be a valuable PET-tracer in recurrent prostate cancer (PCa), but still has limited accuracy. RM2 is a gastrin-releasing peptide receptor (GRPr) antagonist that binds to GRPr on PCa cells. Recent studies suggest that GRPr imaging with PET/CT is a promising technique for staging and restaging of PCa. We explore the value of GRPr-PET using the (68)Ga-labeled GRPr antagonist RM2 in a selected population of patients with biochemically recurrent PCa and a negative/inconclusive (18)FECH-PET/CT...

Over the past 25 years, the average life expectancy for men has increased almost 4 years, and the age of prostate cancer detection has decreased an average of 10 years with diagnosis increasingly made at early-stage disease where curative therapy is possible. These changing trends in the age and extent of malignancy at diagnosis have revealed limitations in conventional curative therapies for prostate cancer, including a significant risk of aggressive cancer recurrence, and the risk of long-term genitourinary morbidity and its detrimental impact on patient's quality of life (QOL)...

BACKGROUND: Optimal management of locally recurrent prostate cancer after definitive radiation therapy is still challenging. With the development of highly accurate radiotherapy devices, prostate salvage re-irradiation might generate lower toxicity rates than classical salvage therapies. We retrospectively evaluated the toxicity and the feasibility of a prostate re-irradiation after definitive radiation therapy failure. Two modalities were investigated: high-dose-rate brachytherapy (HDRB) on whole prostate gland and focal stereotactic radiotherapy (SBRT) using CyberKnife® linac...

Focal therapy involving destruction of prostate specific region containing a clinically meaningful tumor is a new treatment for prostate cancer. Despite the absence of long-term results of applying this method of treatment, there are prerequisites that allow to consider focal therapy as a method with a lower risk of side effects typical of conventional treatment. Focal laser thermocoagulation is a developing technique with a number of advantages, the most important of which is the ability to perform the treatment under the real-time magnetic resonance imaging control...
