Abstract
OBJECTIVE To assess histopathological outcomes, as well as feasibility and safety of targeted microwave ablation (TMA) via the Trinity® system (KOELIS, La Tronche, France). PATIENTS AND METHODS Prospective, single-institution, interventional Phase IIa study with an 'ablate-and-resect' design. In all, 11 patients diagnosed with localised prostate cancer (PCa) underwent TMA via the Trinity system under conscious sedation in an outpatient setting using a single transrectal TATO® 18-G antenna with different treatment regimens. Magnetic resonance imaging (MRI) and robot-assisted radical prostatectomy (RARP) were conducted at 7 days and 1 month after TMA, respectively. Nine patients received RARP, and two patients chose to withdraw their consent following TMA. These men chose an active surveillance protocol upon confirmation of a low-risk prostate cancer diagnosis. Functional outcomes and adverse events were evaluated at baseline and follow-up visits using validated questionnaires. Prostate volumetry and confirmation of necrosis were carried out through MRI and whole-mount histopathological examination. RESULTS The TMA was successfully executed, and all patients were discharged on the same day. No severe adverse events (Common Terminology Criteria for Adverse Events Grade ≥3) were reported at the 7-day and 1-month follow-up visits. Additionally, no declines were observed in urinary, sexual and ejaculation functional outcomes. T1-weighted MRI revealed clear and well-defined ablation zones. The RARP was executed without difficulty, particularly during the dissection of the posterior plane. As a result, no intraoperative complications were encountered. Histopathological assessment on surgical specimens confirmed the absence of viable cells, indicating complete necrosis of the ablative zone if a power intensity >10 W was used during TMA. Ablation zone volumetry revealed no notable distinctions between the three-dimensional segmentation of the virtual ablation zone at TMA (median volume: 2 mL) and MRI (median volume: 1.923 mL). Conversely, a significant reduction was noted in the surgical specimen (median volume: 0.221 mL). CONCLUSIONS Targeted microwave ablation via the Trinity system for localised PCa treatment proves to be a secure and feasible procedure, with complete necrosis evidence within the ablation zone on surgical specimens.

Abstract
OBJECTIVES To study the functional and oncological results of minimally invasive treatment methods: cryoablation, brachytherapy, and high-intensity focused ultrasound (HIFU) therapy of localized prostate cancer in a single hospital. METHODS One hundred sixty patients with localized prostate cancer were treated with minimally invasive methods (53, 52, 55 patients with cryoablation, brachytherapy and HIFU therapy, respectively). Prostate-specific antigen and evaluation of post-procedure biopsies were used as an assessment. The review of functional indicators and quality of life was made with International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), quality of life (QoL) questionnaires. RESULTS Patients after cryoablation showed worse results of oncological control according to positive repeat biopsies, best indicators were observed after brachytherapy. When considering the IPSS results, there were statistically significantly worse scores in the brachytherapy group in the early postoperative period, these differences do not reach statistical significance in the late period in the brachytherapy and cryoablation groups. Patients in the cryoablation group showed worse indicators of IIEF-5; in the early postoperative period; in the late follow-up period, the indicators of erectile function in patients in the cryoablation group did not statistically significantly differ from those in patients after brachytherapy. Patients after HIFU therapy showed fewer cases of de novo erectile dysfunction during the follow-up period of 3 years, higher average IIEF-5 scores, lower IPSS scores and better QoL results. CONCLUSION The recurrence of prostate cancer was statistically significantly higher in the International Society of Urological Pathology (ISUP) 3 grade group. HIFU therapy had better urination indicators compared to other groups, that can be associated with the laser enucleation of prostatic hyperplasia. The advantage was noted in patients after HIFU therapy when comparing the parameters to the IIEF-5 thus, HIFU treatment had a better impact on patients' QoL with localized prostate cancer.

Abstract
OBJECTIVE To evaluate the additional value of prostate-specific membrane antigen positron emission tomography (PSMA-PET) to conventional diagnostic tools to select patients for hemi-ablative focal therapy (FT). PATIENTS AND METHODS We performed a retrospective analysis on a multicentre cohort (private and institutional) of 138 patients who underwent multiparametric magnetic resonance imaging (mpMRI), PSMA-PET, and systematic biopsies prior to radical prostatectomy between January 2011 and July 2021. Patients were eligible when they met the consensus criteria for FT: PSA <15 ng/mL, clinical/radiological T stage ≤T2b, and International Society of Urological Pathology (ISUP) grade 2-3. Clinically significant prostate cancer (csPCa) was defined as ISUP grade ≥2, extracapsular extension >0.5 mm or seminal vesicle involvement at final histopathology. The diagnostic accuracy of mpMRI, systematic biopsies and PSMA-PET for csPCa (separate and combined) was calculated within a four-quadrant prostate model by receiver-operating characteristic and 2 × 2 contingency analysis. Additionally, we assessed whether the diagnostic tools correctly identified patients suitable for hemi-ablative FT. RESULTS In total 552 prostate quadrants were analysed and 272 (49%) contained csPCa on final histopathology. The area under the curve, sensitivity, specificity, positive predictive value and negative predictive value for csPCa were 0.79, 75%, 83%, 81% and 77%, respectively, for combined mpMRI and systematic biopsies, and improved after addition of PSMA-PET to 0.84, 87%, 80%, 81% and 86%, respectively (P < 0.001). On final histopathology 46/138 patients (33%) were not suitable for hemi-ablative FT. Addition of PSMA-PET correctly identified 26/46 (57%) non-suitable patients and resulted in 4/138 (3%) false-positive exclusions. CONCLUSIONS Addition of PSMA-PET to the conventional work-up by mpMRI and systematic biopsies could improve selection for hemi-ablative FT and guide exclusion of patients for whom whole-gland treatments might be a more suitable treatment option.

Abstract
Prostate imaging techniques have progressed across the years allowing for a better detection and characterization of prostate cancer (PCa) lesions. These advancements have led to the possibility to also improve and tailor the treatments on the most aggressive lesion, defined as Index Lesion (IL), to reduce morbidity. The IL is, indeed, considered as the entity which encompass the most aggressive features in prostate cancer disease. Multiparametric magnetic resonance imaging (mpMRI) has emerged as the suggested tool to detect the disease and plan treatments, including those under investigation such as focal therapy (FT). Our review aimed to query the literature on the ability of mpMRI in IL detection and to explore the future perspectives in PCa IL diagnosis. A review of the literature was performed from January 2010 to July 2023. All studies investigating the performance of mpMRI and other main imaging techniques able to detect the IL were assessed and evaluated. mpMRI performs well in the detection of IL with a sensitivity which reaches 71% to 94% among the different studies. However, mpMRI seems to have limited sensitivity in the detection of small tumours (<0.5 mL) and low-grade histology lesions. To overcome these limitations other diagnostic imaging techniques have been proposed. Multiparametric Ultrasound has shown results comparable to mpMRI while detecting 4.3% fewer clinically significant PCa (P=0.042). Positron emission tomography-based modalities using PSMA seems to have higher sensitivity than mpMRI, being able to yield from 13.5% to 18.2% additional cancers. MRI has emerged as the recommended tool since most of the IL can be easily identified, and is the imaging of choice while selecting patients for FT. Other imaging modalities has been proposed to improve PCa lesions detection, but results need to be confirmed by ongoing randomized controlled trial.

Abstract
PURPOSE Vascular-targeted photodynamic therapy (VTP) is an approved treatment option for unilateral low-risk prostate cancer (PCa). METHODS Patients with unilateral low- or intermediate-risk PCa undergoing hemiablation by VTP were evaluated in a real-world setting. Oncological outcome after VTP was measured by MRI-based re-biopsy at 12 and 24 months. Functional outcome after 1 year was investigated by IIEF-5 and IPSS questionnaires. Progression was defined as the evidence3 of ISUP ≥ 2 PCa. RESULTS At any control biopsy (n = 46) after VTP, only 37% of patients showed no evidence of PCa. Recurrence-free survival was 20 months (95% CI 4.9-45.5) and progression-free survival was 38.5 months (95% CI 33.5-43.6 months). In-field and out-field recurrent PCa occurs in 37% (55% ISUP ≥ 2 PCa) and 35% (56% ISUP ≥ 2 PCa). Seventy-nine percent of patients preserved erectile function, respectively. Ten percent of patients presented long-term bladder outlet obstruction. None of the patients presented incontinence. CONCLUSION Due to the high-recurrence in- and out-field recurrence rate in a mainly low-risk prostate cancer cohort, VTP has to be regarded critically as a therapy option in these patients. Pre-interventional diagnostic evaluation is the main issue before focal therapy to reduce the risk of tumor recurrence and progression.

Abstract
Prostate cancer is one of the most common tumors among the male population. Magnetic resonance imaging (MRI), standardized by the PI-RADS version 2.1 scoring system, has a fundamental role in detecting prostate cancer and evaluating its aggressiveness. Diffusion-weighted imaging sequences and apparent diffusion coefficient values, in particular, are considered fundamental for the detection and characterization of lesions. In 2016 the International Society of Urological Pathology introduced a new anatomopathological 5-grade scoring system for prostate cancer. The aim of this study is to evaluate the correlation between quantitative apparent diffusion coefficient values (ADC) derived from diffusion-weighted imaging (DWI) sequences and the International Society of Urological Pathology (ISUP) and PI-RADS groups. Our retrospective study included 143 patients with 154 suspicious lesions, observed on prostate magnetic resonance imaging and compared with the histological results of the biopsy. We observed that ADC values can aid in discriminating between not clinically significant (ISUP 1) and clinically significant (ISUP 2-5) prostate cancers. In fact, ADC values were lower in ISUP 5 lesions than in negative lesions. We also found a correlation between ADC values and PI-RADS groups; we noted lower ADC values in the PI-RADS 5 and PI-RADS 4 groups than in the PI-RADS 3 group. In conclusion, quantitative apparent diffusion coefficient values can be useful to assess the aggressiveness of prostate cancer.

Abstract
PURPOSE Focal therapy (FT) is gaining increasing acceptance in the management of localized prostate cancer particularly due to its favorable safety. Preliminary evidence suggests advantageous utilization of local treatment in the field of oligometastatic prostate cancer (OMPC). Since data on the utilization of FT in OMPC are scarce, we sought to summarize available evidence. METHODS For this narrative comprehensive review, we employed PubMed®, Web of Science™, Embase®, Scopus®, and clinicaltrial.gov databases and Google web search engine to seek peer-reviewed articles, published abstracts from international congresses, and ongoing trials in the English language using the terms "prostate cancer", "oligometastatic", "hormone-sensitive", "focal therapy", "focal treatment", "cryotherapy", "ablation", "cancer" as well as "metastasis-directed therapy. We focused on relevant publications on FT utilized in OMPC targeting the primary or metastatic sites as well as completed and ongoing clinical trials. RESULTS Growing evidence points to distinct differences in the biologic behavior and molecular signaling processes of OMPC as compared to polymetastatic disease (PMPC). No established biomarkers are available to accurately identify OMPC yet, while several candidates are currently under investigation. The evolution of molecular imaging is set to aid in selecting patients benefitting most from local management. Differences between OMPC and PMPC should be considered when designing the optimal therapeutic strategy. While efficacy data for FT in comparison to standard care in OMPC are scarce, longer progression-free survival and time to castration resistance have been demonstrated for bone metastatic prostate cancer with the primary tumor treated by cryosurgery followed by androgen deprivation therapy (ADT) compared to ADT alone. CONCLUSION Ongoing research efforts are eagerly awaited to better characterize OMPC and establish customized strategies for patients with this condition.

Abstract
Breast cancer is a problem for women's health globally. Early detection techniques come in a variety of forms ranging from local to systemic and from non-invasive to invasive. The treatment of cancer has always been challenging despite the availability of a wide range of therapeutics. This is either due to the variable behaviour and heterogeneity of the proliferating cells and/or the individual's response towards the treatment applied. However, advancements in cancer biology and scientific technology have changed the course of the cancer treatment approach. This current review briefly encompasses the diagnostics, the latest and most recent breakthrough strategies and challenges, and the limitations in fighting breast cancer, emphasising the development of breast cancer vaccines. It also includes the filed/granted patents referring to the same aspects.

Abstract
Our study explored frozen section reliability in prostate cancer (PCa) diagnoses and described surgical steps of a 3D magnetic resonance imaging (MRI)-ultrasound (US)-guided prostate biopsy (PB) and focal cryoablation of the index lesion (IL) in a single-setting procedure. Patients with a suspicious prostatic specific antigen (PSA) value, with a PIRADS 4 or 5 single lesion, were enrolled for trans perineal 3D MRI-US-guided PB and TRUS-guided focal cryoablation. Three cores were taken from the IL, three cores from the surrounding area, while systematic sampling was performed for the rest of the gland. After confirmation of PCa in frozen sections, focal cryoablation was performed. The 1st-year follow-up schedule included a PSA test at a 3-month interval, MRI 3 months and 1 year postoperatively and PB of the treated area at 1 year. Following the follow-up schedule, an involved PSA test at a 3-month interval and yearly MRI were performed. The PCa diagnosis was histologically confirmed in all three patients with frozen sections. At final histology, a single Gleason score upgrade from 6 (3 + 3) to 7 (3 + 4) was observed. All patients were discharged on postoperative day 1. At the 3-month evaluation, mean PSA values decreased from 12.54 (baseline) to 1.73 ng/mL and MRI images showed complete ablation of the IL in all patients. Urinary continence and potency were preserved in all patients. At the 1-year follow-up, one patient had suspicious ipsilateral recurrence on MRI and underwent a new analogous procedure. Post follow-up was uneventful and PSA remained stable in all patients. Three-dimensional MRI-US-guided frozen sectioning and focal cryoablation of the IL is a step forward towards a "patient-tailored" minimally invasive approach to the diagnosis and cure of PCa.

Kobayashi S, King F, Hata N. Automatic segmentation of prostate and extracapsular structures in MRI to predict needle deflection in percutaneous prostate intervention. Int J Comput Assist Radiol Surg 2023; 18:449-460. [PMID: 36152168 PMCID: PMC9974805 DOI: 10.1007/s11548-022-02757-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 09/13/2022] [Indexed: 11/05/2022]
Abstract
PURPOSE Understanding the three-dimensional anatomy of percutaneous intervention in prostate cancer is essential to avoid complications. Recently, attempts have been made to use machine learning to automate the segmentation of functional structures such as the prostate gland, rectum, and bladder. However, a paucity of material is available to segment extracapsular structures that are known to cause needle deflection during percutaneous interventions. This research aims to explore the feasibility of the automatic segmentation of prostate and extracapsular structures to predict needle deflection. METHODS Using pelvic magnetic resonance imagings (MRIs), 3D U-Net was trained and optimized for the prostate and extracapsular structures (bladder, rectum, pubic bone, pelvic diaphragm muscle, bulbospongiosus muscle, bull of the penis, ischiocavernosus muscle, crus of the penis, transverse perineal muscle, obturator internus muscle, and seminal vesicle). The segmentation accuracy was validated by putting intra-procedural MRIs into the 3D U-Net to segment the prostate and extracapsular structures in the image. Then, the segmented structures were used to predict deflected needle path in in-bore MRI-guided biopsy using a model-based approach. RESULTS The 3D U-Net yielded Dice scores to parenchymal organs (0.61-0.83), such as prostate, bladder, rectum, bulb of the penis, crus of the penis, but lower in muscle structures (0.03-0.31), except and obturator internus muscle (0.71). The 3D U-Net showed higher Dice scores for functional structures ([Formula: see text]0.001) and complication-related structures ([Formula: see text]0.001). The segmentation of extracapsular anatomies helped to predict the deflected needle path in MRI-guided prostate interventions of the prostate with the accuracy of 0.9 to 4.9 mm. CONCLUSION Our segmentation method using 3D U-Net provided an accurate anatomical understanding of the prostate and extracapsular structures. In addition, our method was suitable for segmenting functional and complication-related structures. Finally, 3D images of the prostate and extracapsular structures could simulate the needle pathway to predict needle deflections.

Abstract
OBJECTIVES To evaluate the safety and efficacy transcatheter arterial chemoembolization (TACE) for the treatment of refractory gross hematuria (RGH) and urinary retention (UR) secondary to localized advanced prostate cancer (PCa). PATIENTS AND METHODS Thirty-two patients (mean age 72.5 years, range 60-89) with advanced PCa-related RGH that failed conventional therapy were included. Twenty-two of these patients had catheter-dependent due to PCa-related UR. TACE was performed with epirubicin (EPI)-eluting HepaSpheres (HS) plus intra-arterial (IA) infusion of docetaxel. Technical success, adverse events (AEs), overall survival (OS), control of RGH, removal of indwelling catheters, and local disease control, were evaluated. RESULTS Technical success was achieved in 100% without major AEs. Mean follow up post-TACE was 27 months (range 8-56 months) with a mean OS of 30 months. GRH stopped within 5 days after TACE in all patients, 26 (86.7%) of these patients exhibited good bleeding control during a mean follow-up of 24 months; 17 (77.3%) of the 22 patients with UR had recovered spontaneous urination, 15 (88.2%) patients were catheter-free at their last follow-up with a mean of 24 months. BS was obtained in 73.3% (22/30) of patients at a mean follow-up of 29 months. At the last visit, 22 patients had a mean of 36 months follow-up and the mean percentage reduction in prostate volume was 55.5%, with a statistically different from baseline (P = 0.022). Negative biopsy results were obtained in 84.2% (16/19) of the patients at 12-47 months after TACE. Compared with baseline values, there was a significant improvements in IPSS, QoL, Qmax, and PVR (all P < 0.05). CONCLUSIONS TACE using EPI-eluting HS plus IA infusion of docetaxel is a safe and effective treatment option for the advanced PCa patients with GRH and UR, and it could be considered as an alternative if there was no other therapeutic choice.

Ipsilateral hemigland prostate biopsy may underestimate cancer burden in patients with unilateral mpMRI-visible lesions. Abdom Radiol (NY) 2023; 48:1079-1089. [PMID: 36526922 PMCID: PMC10765956 DOI: 10.1007/s00261-022-03775-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 12/07/2022] [Accepted: 12/08/2022] [Indexed: 12/23/2022]
Abstract
PURPOSE To evaluate the cancer detection rates of reduced-core biopsy schemes in patients with unilateral mpMRI-visible intraprostatic lesions and to analyze the contribution of systematic biopsy cores in clinically significant prostate cancer (csPCa) detection. METHODS 212 patients with mpMRI-visible unilateral intraprostatic lesions undergoing MRI/TRUS fusion-guided targeted biopsy (TBx) and systematic biopsy (SBx) were included. Cancer detection rates of TBx + SBx, as determined by highest Gleason Grade Group (GG), were compared to 3 reduced-core biopsy schemes: TBx alone, TBx + ipsilateral systematic biopsy (IBx; MRI-positive hemigland), and TBx + contralateral systematic biopsy (CBx; MRI-negative hemigland). Patient-level and biopsy core-level data were analyzed using descriptive statistics with confidence intervals. Univariable and multivariable logistic regression analysis was conducted to identify predictors of csPCa (≥ GG2) detected in MRI-negative hemiglands at p < 0.05. RESULTS Overall, 43.4% (92/212) of patients had csPCa and 66.0% (140/212) of patients had any PCa detected by TBx + SBx. Of patients with csPCa, 81.5% had exclusively ipsilateral involvement (MRI-positive), 7.6% had only contralateral involvement (MRI-negative), and 10.9% had bilateral involvement. The csPCa detection rates of reduced-core biopsy schemes were 35.4% (75/212), 40.1% (85/212), and 39.6% (84/212) for TBx alone, TBx + IBx, and TBx + CBx, respectively, with detection sensitivities of 81.5%, 92.4%, and 91.3% compared to TBx + SBx. CONCLUSION Reduced-core prostate biopsy strategies confined to the ipsilateral hemigland underestimate csPCa burden by at least 8% in patients with unilateral mpMRI-visible intraprostatic lesions. The combined TBx + SBx strategy maximizes csPCa detection.

Abstract
OBJECTIVE To provide a summary and discussion of international guidelines, position statements and consensus statements in relation to focal therapy (FT) for prostate cancer (PCa). METHODS The European Association of Urology-European Association of Nuclear Medicine-European Society for Radiotherapy and Oncology-European Society of Urogential Radiology-International Society of Urological Pathology-International Society of Geriatric Oncology and American Urological Association-American Society for Radiation Oncology-Society of Urologic Oncology guidelines were interrogated for recommendations for FT. PubMed and Ovid Medline were searched for consensus statements. Only studies in English since 2015 were included. Reference lists of the included articles were also interrogated and a manual search for studies was also performed. RESULTS Our results showed a lack of long-term randomised data for FT. International Urological guidelines emphasised the need for more high-quality clinical trials with robust oncological and toxicity outcomes. Consensus and positions statements were heterogenous. CONCLUSION A globally accepted guideline for FT planning, technique and follow-up are still yet to be determined. Well-designed studies with long-term follow-up and robust clinical and toxicity endpoints are needed to improve our understanding of FT and create uniform guidelines to streamline management and follow-up.

Abstract
INTRODUCTION/BACKGROUND Only 1 randomized controlled trial has compared focal therapy and active surveillance (AS) for the low-risk prostate cancer (PCa). We investigated whether focal HIFU (fHIFU) yields oncologic advantages over AS for low-risk PCa. MATERIALS AND METHODS We included 2 non-randomized prospective series of 132 (fHIFU) and 421 (AS) consecutive patients diagnosed with ISUP 1 PCa between 2008 and 2018. A matched pair analysis was performed to decrease potential bias. Study main outcomes were freedom from radical treatment (RT) or androgen-deprivation therapy (ADT), treatment-free survival (TFS), time to metastasis, and overall survival (OS). RESULTS Median fHIFU follow-up was 50 months (interquartile range, 29-84 months). Among matched variables, no major differences were recorded except for AS having more suspicious digital rectal examination findings (P = .0074) and recent enrollment year (P = .0005). Five-year intervention-free survival from RT or ADT was higher for the fHIFU cohort (67.4% vs. 53.8%; P = .0158). Time to treatment was approximately 10 months shorter for AS than for fHIFU (time to RT, P = .0363; time to RT or ADT, P = .0156; time to any treatment, P = .0319). No differences were found in any-TFS (fHIFU, 61.4% vs. AS, 53.8%; P = .2635), OS (fHIFU, 97% vs. AS, 97%; P = .9237), or metastasis (n = 0 in fHIFU and n = 2 in AS; P = .4981). Major complications (≥ Clavien 3) were rare (n = 4), although 36.4% of men experienced complications. No relevant changes were noted in continence (P = .3949). CONCLUSION At a 4-year median follow-up, fHIFU for mainly low-risk PCa (ISUP grade 1) is safe, may decrease the need for radical treatment or ADT and may allow longer time to treatment compared to AS. Nonetheless, no advantages are seen in PCa progression and/or death (OS).

Abstract
Objectives To assess the patient preferences and utility scores for the different conventional and innovative treatment modalities for localised prostate cancer (PCa). Subjects and Methods Patients treated for localised PCa and healthy volunteers were invited to fill out a treatment-outcome scenario questionnaire. Participants ranked six different treatments for localised PCa from most to least favourable, prior to information. In a next step, treatment procedures, toxicity, risk of biochemical recurrence and follow-up regimen were comprehensibly described for each of the six treatments (i.e. treatment-outcome scenarios), after which patients re-ranked the six treatments. Additionally, participants gave a visual analogue scale (VAS) and time trade-off (TTO) score for each scenario. Differences between utility scores were tested by Friedman tests with post hoc Wilcoxon signed-rank tests. Results Eighty patients and twenty-nine healthy volunteers were included in the study. Before receiving treatment-outcome scenario information, participants ranked magnetic resonance-guided adaptive radiotherapy most often as their first choice (35%). After treatment information was received, active surveillance was most often ranked as the first choice (41%). Utility scores were significantly different between the six treatment-outcome scenarios, and active surveillance, non- and minimal-invasive treatments received higher scores. Conclusions Active surveillance and non-invasive treatment for localised PCa were the most preferred options by PCa patients and healthy volunteers and received among the highest utility scores. Treatment preferences change after treatment information is received.

Abstract
BACKGROUND Focal therapy (FT) for prostate cancer (PCa) is promising. However, long-term oncological results are awaited and there is no consensus on follow-up strategies. Molecular biomarkers (MB) may be useful in selecting, treating and following up men undergoing FT, though there is limited evidence in this field to guide practice. We aimed to conduct a consensus meeting, endorsed by the Focal Therapy Society, amongst a large group of experts, to understand the potential utility of MB in FT for localized PCa. METHODS A 38-item questionnaire was built following a literature search. The authors then performed three rounds of a Delphi Consensus using DelphiManager, using the GRADE grid scoring system, followed by a face-to-face expert meeting. Three areas of interest were identified and covered concerning MB for FT, 1) the current/present role; 2) the potential/future role; 3) the recommended features for future studies. Consensus was defined using a 70% agreement threshold. RESULTS Of 95 invited experts, 42 (44.2%) completed the three Delphi rounds. Twenty-four items reached a consensus and they were then approved at the meeting involving (N.=15) experts. Fourteen items reached a consensus on uncertainty, or they did not reach a consensus. They were re-discussed, resulting in a consensus (N.=3), a consensus on a partial agreement (N.=1), and a consensus on uncertainty (N.=10). A final list of statements were derived from the approved and discussed items, with the addition of three generated statements, to provide guidance regarding MB in the context of FT for localized PCa. Research efforts in this field should be considered a priority. CONCLUSIONS The present study detailed an initial consensus on the use of MB in FT for PCa. This is until evidence becomes available on the subject.

Outcomes of Salvage Robot-assisted Radical Prostatectomy After Focal Ablation for Prostate Cancer in Comparison to Primary Robot-assisted Radical Prostatectomy: A Matched Analysis. Eur Urol Focus 2022; 8:1192-1197. [PMID: 34736871 DOI: 10.1016/j.euf.2021.10.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 09/08/2021] [Accepted: 10/05/2021] [Indexed: 01/25/2023]
Abstract
BACKGROUND Focal therapy (FT) for prostate cancer is less invasive than radical treatment but carries a risk of recurrence. Salvage robot-assisted radical prostatectomy (S-RARP) is a possible option after FT failure. OBJECTIVE To evaluate the impact of FT on functional and oncological outcomes following S-RARP. DESIGN, SETTING, AND PARTICIPANTS In a retrospective analysis of data from a prospectively collected institutional database, 53 patients who underwent S-RARP following failure of focal ablation were selected as group I; patients who had whole-gland ablation and external beam therapy were excluded. This group was matched to a control sample (matched at ratios of 1:1, 1:2, 1:3, 1:4) of men who had undergone primary RARP, using age, prostate-specific antigen (PSA), PSA density, body mass index, Sexual Health Inventory for Men score, American Urological Association symptom score, Charlson comorbidity index, prostate weight, preoperative Gleason score (GS), and history of smoking as variables. SURGICAL PROCEDURE S-RARP after FT was performed using a standardized technique developed at our institute with the da Vinci Xi Surgical System. MEASUREMENTS Oncological and functional outcomes were compared between the S-RARP and primary RARP groups. RESULTS AND LIMITATIONS There was no difference in estimated blood loss (p = 0.8) between the 1:1 matched groups, but operating room time was significantly longer for S-RARP (p = 0.007). The primary RARP group had a higher proportion of patients who underwent a full nerve-sparing procedure. The S-RARP group had higher incidence of positive surgical margins (40% vs 15%; p = 0.008), GS ≥8 (25% vs 15%; p = 0.07), and positive lymph node status (9.4% vs 5.7%; p = 0.02). There was no significant difference in overall complications between the groups. The primary RARP group had a higher incidence of lymphocele drainage after surgery (15% vs 0%; p = 0.006). The main limitation of the study is its retrospective design. CONCLUSIONS S-RALP after FT failure is feasible; however, surgery following FT leads to poorer oncological and functional outcomes. Despite the targeted nature of FT, significant nonfocal collateral damage is evident in tissues surrounding the prostate, which in turn translates to poorer functional outcomes after S-RARP. PATIENT SUMMARY We studied the surgical challenges during robot-assisted removal of the prostate after previous focal treatment (FT) for prostate cancer and compared the outcomes to those for robot-assisted prostate removal in patients who had no previous FT. We found that this technique is safe and effective with a limited risk of complications, but poor urinary and sexual functional outcomes.

Abstract
There has been an increasing role of magnetic resonance imaging (MRI) in the management of prostate cancer. MRI already plays an essential role in the detection and staging, with the introduction of functional MRI sequences. Recent advancements in radiomics and artificial intelligence are being tested to potentially improve detection, assessment of aggressiveness, and provide usefulness as a prognostic marker. MRI can improve pretreatment risk stratification and therefore selection of and follow-up of patients for active surveillance. MRI can also assist in guiding targeted biopsy, treatment planning and follow-up after treatment to assess local recurrence. MRI has gained importance in the evaluation of metastatic disease with emerging technology including whole-body MRI and integrated positron emission tomography/MRI, allowing for not only better detection but also quantification. The main goal of this article is to review the most recent advances on MRI in prostate cancer and provide insights into its potential clinical roles from the radiologist's perspective. In each of the sections, specific roles of MRI tailored to each clinical setting are discussed along with its strengths and weakness including already established material related to MRI and the introduction of recent advancements on MRI.

Abstract
Purpose To describe the development and first outcomes of the Utrecht Prostate Cohort (UPC): the first ‘trials within cohorts’ (TwiCs) platform for prostate cancer (PCa). Methods All non-metastasized, histologically proven PCa patients who are planned to receive standard of care are eligible for inclusion in UPC. Patients provide informed consent for the collection of clinical and technical patient data, physician-reported outcomes, and patient-reported outcomes (PROs) up to 10 years post-treatment. Additionally, patients may provide broad consent for future randomization for experimental-intervention trials (TwiCs). Changes in PROs (EPIC-26 questionnaire domains) of the participants who received standard of care were analyzed using Wilcoxon signed-rank tests. Results In two years, 626 patients were enrolled, 503 (80.4%) of whom provided broad consent for future randomization. Among these, 293 (46.8%) patients underwent magnetic resonance-guided adaptive radiotherapy (MRgRT), 116 (18.5%) CT-guided external beam radiation therapy (EBRT), 109 (17.4%) robot-assisted radical prostatectomy (RARP), and 65 (10.4%) patients opted for active surveillance. Patients treated with MRgRT and CT-guided EBRT showed a transient but significant decline in urinary irritative/obstructive and bowel domain scores at 1-month follow-up. RARP patients showed a significant deterioration of urinary incontinence domain scores between baseline and all follow-up moments and significant improvement of urinary irritative/obstructive domain scores between baseline and 9- and 12-month follow-up. All radical treatment groups showed a significant decline in sexual domain scores during follow-up. Active surveillance patients showed no significant deterioration over time in all domains. Conclusion The first results from the UPC study show distinct differences in PROs between treatment options for PCa. Registration No.: NCT04228211.

A Prospective Pilot Study Investigating Performance of 18F-Fluciclovine PET Imaging for Detection of Prostate Cancer 2 Years Following Primary Partial Gland Cryoablation. Nucl Med Mol Imaging 2022; 56:196-201. [PMID: 35846414 PMCID: PMC9276896 DOI: 10.1007/s13139-022-00755-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 05/23/2022] [Accepted: 05/25/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose The goal of partial gland ablation (PGA) is to eradicate focal lesions of clinically significant prostate cancer (csPCa) with minimal adverse impact on functional outcomes. The primary objective of this study is to characterize the performance of 18F-Fluciclovine PET imaging for detection of prostate cancer following PGA. Materials and Methods Subjects 2 years following primary partial gland cryoablation (PPGCA) were invited to participate in an IRB-approved study providing they met the following inclusion criteria: a single reported mpMRI region of interest (ROI) concordant with biopsy Gleason Grade Group (GGG) < 4, no gross extra-prostatic extension on mpMRI, and no GGG > 1 or GGG 1 with a core length > 6 mm on contralateral systematic biopsy. 18F-Fluciclovine PET MRI imaging of the prostate was performed followed by in and out-of-field biopsies. Results Twenty-seven men who met eligibility criteria participated in the prospective study. In-field and out-of-field csPCa recurrence rate was 7.4% and 22.2%, respectively. The sensitivity and positive predictive value of mpMRI and PET imaging did not reach performance to reliably inform who should undergo prostate biopsy. Conclusion At 2 years following PPGCA, the rate of in-field csPCa was exceedingly low indicating a limited role for imaging to inform in-field biopsy decisions. The csPCa detection rate of out-of-field recurrence was 22% which provides an opportunity for imaging to inform out-of-field biopsy decisions. Based on our findings, 18F-Fluciclovine PET MRI cannot be used to inform who should undergo out-of-field prostate biopsy at 2 years following PPGCA.

Cancers (Basel) 2022; 14:cancers14122988.

Abstract
Simple Summary Targeted cryotherapy is an emerging treatment for prostate cancer (PCa). mpMRI is a powerful tool for image fusion techniques that deliver incremental precision in diagnostic and treatment of PCa. Fusion targeted cryotherapy (FTC) arises from the simultaneous application of both these procedures. Recurrence is a concern after any type of PCa treatment, especially after targeted treatments. In this article we investigate the recurrence rate after FTC and the role of Prostate-Specific Antigen (PSA) as a predictor of recurrences. Our research provides new evidence on the feasibility of FCT by providing new insights on patient management. Abstract Targeted therapy (TT) for prostate cancer (PCa) aims to ablate the malignant lesion with an adequate margin of safety in order to obtain similar oncological outcomes, but with less toxicity than radical treatments. The main aim of this study was to evaluate the recurrence rate (RR) in patients with primary localized PCa undergoing mpMRI/US fusion targeted cryotherapy (FTC). A secondary objective was to evaluate prostate-specific antigen (PSA) as a predictor of recurrences. We designed a prospective single-center single-cohort study. Patients with primary localized PCa, mono or multifocal lesions, PSA ≤ 15 ng/mL, and a Gleason score (GS) ≤ 4 + 3 undergoing FTC were enrolled. RR was chosen as the primary outcome. Recurrence was defined as the presence of clinically significant prostate cancer in the treated areas. PSA values measured at different times were tested as predictors of recurrence. Continuous variables were assessed with the Bayesian t-test and categorical assessments with the chix-squared test. Univariate and logistic regression assessment were used for predictions. A total of 75 cases were included in the study. Ten subjects developed a recurrence (RR: 15.2%), while fifty-six (84.8%) patients showed a recurrence-free status. A %PSA drop of 31.5% during the first 12 months after treatment predicted a recurrence with a sensitivity of 53.8% and a specificity of 79.2%. A PSA drop of 55.3% 12 months after treatment predicted a recurrence with a sensitivity of 91.7% and a specificity of 51.9%. FTC for primary localized PCa seems to be associated with a low but not negligible percentage of recurrences. Serum PSA levels may have a role indicating RR.

Alternative- and focal therapy trends for prostate cancer: a total population analysis of in-patient treatments in Germany from 2006 to 2019. World J Urol 2022; 40:1645-1652. [PMID: 35562598 PMCID: PMC9236973 DOI: 10.1007/s00345-022-04024-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 04/22/2022] [Indexed: 12/24/2022] Open
Abstract
Purpose Focal therapy (FT) offers an alternative approach for prostate cancer (PCa) treatment in selected patients. However, little is known on its actual establishment in health care reality. Patients and methods We defined FT as high-intensity focused ultrasound (HIFU), hyperthermia ablation, cryotherapy, transurethral ultrasound ablation (TULSA) or vascular-targeted photodynamic therapy (VTP) TOOKAD®. We analyzed the nationwide German hospital billing database for a PCa diagnosis in combination with FT. For analyses on the hospital level, we used the reimbursement.INFO tool based on hospitals’ quality reports. The study period was 2006 to 2019. Results We identified 23,677 cases of FT from 2006 to 2019. Considering all PCa cases with surgery, radiotherapy or FT, the share of FT was stable at 4%. The annual caseload of FT increased to a maximum of 2653 cases in 2008 (p < 0.001) and then decreased to 1182 cases in 2014 (p < 0.001). Since 2015, the cases of FT remained on a plateau around 1400 cases per year. The share of HIFU was stable at 92–96% from 2006 to 2017 and decreased thereafter to 75% in 2019 (p = 0.015). In 2019, VTP-TOOKAD® increased to 11.5% and TULSA to 6%. In 2006, 21% (62/299) of urological departments performed FT and 20 departments reached > 20 FT procedures. In 2019, 16% (58/368) of urological departments performed FT and 7 departments reached > 20 FT. In 2019, 25 urological departments offered FT other than HIFU: 5 centers hyperthermia ablation, 11 centers VTP TOOKAD®, 3 centers cryotherapy, 6 centers TULSA. Conclusion The FT development in Germany followed the Gartner hype cycle. While HIFU treatment is the most commonly performed FT, the share of newer FT modalities such as VTP-TOOKAD® and TULSA is remarkably increasing.

Abstract
OBJECTIVE The objective of this non-clinical study and clinical trial (phase II) was to examine the safety and efficacy of microwave tissue coagulation (MTC) for prostate cancer and assess its use in lesion-targeted focal therapy. METHODS In the non-clinical study using Microtaze®-AFM-712 (Alfresa-pharma Corporation) with an MTC-needle, MTC was performed by a transperineal approach to canine prostatic-targeted tissue under real-time ultrasound guidance. Using various MTC-output and irradiation-time combinations, the targeted and surrounding tissues (rectum, bladder, and fat) were examined to confirm the extent of coagulative necrosis or potential cell death, and to compare intra-operative ultrasound and pathology findings. The exploratory clinical trial was conducted to examine the safety and efficacy of MTC. Five selected patients underwent transperineal MTC to clinically single magnetic resonance imaging (MRI)-visible lesions with Gleason score 3+4 or 4+4. Prostate-specific antigen (PSA), MRI, and Expanded Prostate Cancer Index Composite questionnaire findings were compared before and 6 months after surgery. RESULTS The region of coagulative necrosis was predictable by monitoring of ultrasonically visible vaporization; thus, by placing the MTC-needle at a certain distance, we were able to perform a safe procedure without adverse events affecting the surrounding organs. Based on the non-clinical study, which used various combinations of both output and irradiation time, MTC with 30-W output for 60-sec irradiation was selected for the prostate. Based on the predictable necrosis, the therapeutic plan (where to place the MTC-needle to achieve complete ablation of the target and how many sessions) was strictly determined per patient. There were no serious adverse events in all patients and only temporary urinary symptoms related to MTC-therapy were observed. Furthermore, satisfaction of having undergone treatment was very high. All pre-operative MRI-visible lesions disappeared, and PSA decreased 55% 6 months after surgery. CONCLUSION MTC may be an option for lesion-targeted focal therapy for prostate cancer.

Abstract
Laser technology has been used in Urology since the 80s with a lot of different applications in endoscopic and open surgery. With the developments of the technology and the introduction of new active medium and source of laser energy, this technology have become the gold standard not only in stone surgery but even in benign prostate enlargement (BPE) surgical treatment. Regarding urologic oncology, laser energy has now reached an important role in focal therapy and in conservative treatment. The possibility of having better functional outcomes without any relevant impact on oncological results led to an increased use of laser in penile surgery, with a significant mention in urological guidelines for this option. In urothelial cancers as well, both in conservative management of upper tract tumors that in the treatment of non muscle invasive bladder cancer, a clear role of these relatively new source of energy have been demonstrated. Finally, both in prostate that in renal cancer the strategy of focal therapy may take advantage from this precise and fine technology. In this review we analyzed and described the applications of laser energy in urological cancers with a specific focus on penile, urothelial and prostate cancer.

Abstract
PURPOSE OF REVIEW Currently, a significant number of patients are diagnosed with unilateral and apparently unifocal low or intermediate-risk prostate cancer (PCa). These patients are suitable for focal therapy, thus preventing radical treatment side effects without affecting cancer control. Among focal therapy energy sources, laser-based technologies have shown promising outcomes. We aimed to summarize recent data on focal laser ablation (FLA) and vascular-targeted photodynamic therapy (VTP) for PCa. RECENT FINDINGS We selected eight studies reporting data on 1155 patients with PCa who underwent laser-based focal therapy. Five studies were on FLA and three on VTP (six prospective and two retrospective series); four reported both oncologic and functional outcomes whereas in three only oncologic and one only functional outcomes were discussed. Follow-up protocols and durations varied widely among the studies. PCa recurrence rates ranged between 20 and 56%. Urinary and erectile function were preserved after treatment, and complications were mild and transient. A lack of high-quality data on long-term oncological outcomes still remains, thus further highlighting the need for prospective controlled studies. SUMMARY FLA and VTP are well tolerated procedures with excellent functional outcomes. However, both procedures showed a significant rate of PCa recurrence, thus demonstrating a certain grade of oncologic control failure of the procedure and/or nonoptimal patients' selection.

Prevalence and outcomes of focal ablation versus prostatectomy for elderly patients with prostate cancer: a population-based study. JOURNAL OF THE NATIONAL CANCER CENTER 2022; 2:25-32. [PMID: 39035213 PMCID: PMC11256698 DOI: 10.1016/j.jncc.2021.11.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/10/2021] [Accepted: 11/14/2021] [Indexed: 12/20/2022] Open
Abstract
Background Despite rapid advances in the treatment of prostate cancer (PCa), the optimal treatment for elderly patients with PCa remains unclear due to a lack of high-quality evidence. This study aimed to evaluate whether surgical procedures are beneficial for PCa patients aged 75 years and older and compare the effects of focal ablation and prostatectomy. Methods Male patients aged 75 years and older who were diagnosed with Tis-T2/N0/M0 PCa between 2000 and 2017 were retrospectively identified from the Surveillance, Epidemiology, and End Results program database. Cox regression models were used to test for statistical differences between the overall survival (OS) and disease-specific survival (DSS). Results A total of 114,506 patients aged 75 years and older with PCa were included in this study, among which 60,131 died during the study period. The most prevalent surgical procedure for these patients was focal ablation. The local excision rate increased with advancing age, while the prostatectomy rate decreased sharply with age. The proportion of the elderly patients who underwent a focal ablation also increased with the age at diagnosis. The survival rate of patients aged 75 years and older who underwent a focal ablation was significantly worse than that for those who did not undergo any surgical procedures (OS: HR, 1.32, P<0.001; DSS: HR, 1.58, P<0.001). Although only a few of the patients underwent prostatectomy, the procedure was still related to improved OS and DSS (OS: HR, 0.60, P< 0.001; DSS: HR, 0.37, P<0.001) rates. Conclusions Focal ablation has gradually replaced prostatectomy as the most common surgical procedure for elderly patients with PCa in the United States. However, our results revealed that the procedure might not provide benefits for elderly patients with PCa; instead, we found that focal ablation resulted in increased negative effects on patient prognoses. Elderly patients should have the same opportunity to be treated with standard surgical interventions as younger patients.

Abstract
High-intensity focused ultrasound (HIFU) was experimentally used for focal therapy for anti-cancer effects in prostate cancer (PC). Focal therapy is a diagnosis-based investigational treatment option for localized PC that cures clinically significant PC (csPC) while preserving the anatomical structures related to urinary and sexual function based on its spread observed using multi-parametric magnetic resonance imaging (mpMRI). The European Association of Urology indicated that the current status of focal therapy for localized PC was an investigational modality and encouraged prospective recording of outcomes and recruitment of suitable patients in 2018. During the last few years, large-population multi- and single-center prospective studies have investigated focal therapy as a treatment strategy for localized PC. In a multicenter prospective study with 5-year follow-up, failure-free survival, which was defined as avoidance of local salvage therapy (surgery or radiotherapy), systemic therapy, metastases, and prostate cancer-specific death, was 88%. In the previous studies, there was no significant influence on urinary function before and at 3 months after the treatment, although transient impairment was reported 1 month after the treatment. Pad- and leak-free continence was preserved in 80-100% of the patients after treatment. Erectile function was significantly impaired in the initial 3 months after treatment compared to the pretreatment values, but it improved 6 months after the focal therapy in the previous reports. Paired comparison studies and cohort studies with long-term follow-up will contribute to verifying this treatment's clinical outcomes for patients with localized PC.

Abstract
BACKGROUND The existing treatment options for men with intermediate- or high-volume low-risk prostate cancer (PCa) are associated with a substantial risk of over- or undertreatment. The development of risk-adjusted therapies is an unmet need for these patients. OBJECTIVE To describe our novel technique of precision prostatectomy, a form of surgical focal therapy that allows radical excision of the index PCa lesion along with >90% prostatic tissue extirpation while preserving the prostatic capsule and seminal vesicle/vas deferens complex on the side contralateral to the dominant cancer lesion, and to report on medium-term functional and oncologic outcomes in the first 88 consecutive men who underwent this procedure between December 2016 and January 2020. DESIGN, SETTING, AND PARTICIPANTS Men with (1) prostate-specific antigen (PSA) ≤20 ng/ml, (2) clinical T stage ≤cT2, (3) a dominant unilateral lesion with Gleason ≤ 4 + 3 disease with any number or percentage of cores involved ipsilaterally on prostate biopsy, (4) no primary Gleason ≥4 lesion contralaterally, and (5) a preoperative Sexual Health Inventory of Men (SHIM) score of ≥17 (out of 25) with/without phosphodiesterase type-5 inhibitor use who consented to undergo precision prostatectomy were included in this single-arm, single-center, IDEAL stage 2b prospective development study. INTERVENTION Robotic precision prostatectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The safety and urinary, sexual, and oncologic outcomes of the precision prostatectomy technique were studied. Descriptive statistics and Kaplan-Meier analyses were used to assess 12-mo urinary continence (0-1 pad), 12-mo sexual potency (SHIM score ≥17), 36-mo freedom from clinically significant PCa (grade group ≥2), secondary treatments, metastatic disease, and mortality. RESULTS AND LIMITATIONS At study entry, the median age, PSA, and SHIM score were 60.0 yr (interquartile range [IQR] 54.2-65.9), 5.7 ng/ml (IQR 4.2-7.1), and 22 points (IQR 19-24), respectively. The median follow-up was 25 mo (IQR 14-38). At 12 mo, all patients were continent (0-1 pads), with 90.9% of patients using 0 pads. The median time to urinary continence was 1 mo (IQR 1-4). At 12 mo, 85% of all-comers and 90.2% of the preoperatively potent men were potent. The median time to sexual potency was 4 mo (IQR 4-12). From an oncologic standpoint, at 36 mo an estimated 93.4% of the patients were free from clinically significant residual PCa and 91.7% had not undergone any additional treatment. All patients were alive and free of metastatic disease at 36 mo. CONCLUSIONS Precision prostatectomy is technically safe and reproducible and offers excellent postoperative functional results. At 36-mo follow-up, the oncologic outcomes and secondary treatment rates appear to be superior to existing ablative focal therapy results. Pending long-term data, a risk-stratified surgical approach to PCa may avoid whole-gland therapy and preserve functional quality of life in men with localized PCa. PATIENT SUMMARY Precision prostatectomy is a new form of focal therapy for intermediate-risk prostate cancer in which a 5-10-mm rim of prostate capsule is left on the opposite side of the gland to where the dominant cancer is located. The technique appears to be safe and efficacious and adds to the growing armamentarium of risk-adapted therapies for treatment of localized prostate cancer that avoid the adverse effects on urinary and erectile function of whole-gland treatments.

Abstract
PURPOSE OF REVIEW Recent advances in our understanding of prostate cancer genetics have transformed the field. However, challenges in implementation and clinical application remain. The aim of this review is to discuss recent noteworthy publications in prostate cancer germline testing, genetically informed treatment, and polygenetic risk. RECENT FINDINGS The recent U.S. Food and Drug Administration approval of two poly adenosine diphosphate-ribose inhibitors (olaparib and rucaparib) for the treatment of men with metastatic castration-resistant prostate cancer with mutations in DNA damage repair genes and updates to the National Cancer Center Network testing guidelines that expand the eligibility criteria for germline and somatic genetic testing in men with prostate cancer provide an opportunity for a larger portion of the prostate cancer population to access genetic testing and targeted therapies. Due to this, clinicians have needed to rapidly adapt their clinical workflows. Further, the field has renewed efforts to evaluate polygenetic risk profiles to better understand the complex genetic landscape beyond single genes. SUMMARY This review highlights advances in the understanding of prostate cancer genetics, and areas that remain less well defined. Collaboration between multidisciplinary team members is necessary to move this field forward and provide quality, optimal care.

Abstract
PURPOSE The aim of the study was to assess quality of life (QoL), decision involvement, and decisional regret after treatment with vascular-targeted photodynamic therapy (VTP) (TOOKAD®) for unilateral low-risk prostate cancer. METHODS Validated questionnaires (EORTC QLQ-C30 and QLQ-PR25) capturing QoL post-treatment, involvement in decision-making (Control Preferences Scale) and decision regret (Decisional Regret Scale), were given to patients at the 12-month visit after undergoing VTP at our institution between May 2018 and February 2021. RESULTS Out of 44 patients, 36 patients were included in this study and 31 (86.1%) responded to the questionnaires. Mean overall health score capturing QoL at 12 months was 79.3 (standard deviation: ±18.1). 70.9% of the patients (n = 22) had no decision regret, and 67.8% of men (n = 21) had an active role in decision-making. In control biopsy at 12 months post-treatment, 19.4% of patients (n = 7) presented with local recurrence and progression to higher Gleason score (GS) was found in 13.8% of patients (n = 5). Patients (n = 3) presenting with tumor recurrence or progression to higher GS in control biopsy showed a significantly higher level of decision regret (p < 0.009). CONCLUSION Only 9.7% of men (n = 3) felt a strong emotion of regret at 12 months after VTP. Level of decision regret was significantly higher in patients with local recurrence or tumor progression detected in control biopsy. QoL was stable after VTP.

Abstract
Background Focal treatment for prostate cancer (PCa) is a hybrid approach combining ablative treatment of the involved prostate gland and continued active surveillance (AS) of the unaffected gland. Low dose-rate (LDR) brachytherapy can be used as a lesion-targeted focal therapy, however, further studies are required to support its use. The aim of this study is to evaluate the dosimetry, toxicity and oncological outcomes of men receiving lesion-targeted focal LDR brachytherapy for low to intermediate risk PCa. Methods This is a retrospective cohort study of 26 men with unifocal, low to intermediate grade PCa diagnosed on a combination of multiparametric-magnetic resonance imaging (mp-MRI) and targeted plus template transperineal (TP) biopsy, who received focal LDR brachytherapy at a single institution. Brachytherapy involved a single monotherapy implant using iodine-125 seeds to deliver a prescribed dose of 145 Gy to the index lesion. Results The mean focal planning target volume (F-PTV) as a percentage of the prostate volume was 24.5%. The percentage of the focal gross tumour volume (F-GTV) receiving 100% of the prescription dose was 100% for 12 patients and ≥98% for 18 patients. The median follow-up for toxicity and biochemical control outcomes was 23.1 [interquartile range (IQR) 19.1–31.3] and 24.2 (IQR 17.9–30.0) months, respectively. Grade 2 urinary and erectile toxicities were reported by 29.2% and 45.8% of patients, respectively, with resolution of urinary symptoms to baseline by last follow-up. There were no grade ≥3 urinary or erectile toxicities or grade ≥2 rectal toxicity. All 21 patients who underwent a repeat mp-MRI and TP biopsy at 12–24 months post-treatment were negative for clinically significant disease and 25 (96.2%) patients were free from biochemical failure (FFBF). Conclusions Focal LDR brachytherapy is associated with a favourable toxicity profile and a high rate of control of significant PCa at 12–18 months post-treatment. We have commenced the LIBERATE prospective registry in focal LDR brachytherapy based on the highly encouraging outcomes of this initial experience.

Abstract
Radioactive iodine-125 (I-125) is the most widely used radioactive sealed source for interstitial permanent brachytherapy (BT). BT has the exceptional ability to deliver extremely high doses that external beam radiotherapy (EBRT) could never achieve within treated lesions, with the added benefit that doses drop off rapidly outside the target lesion by minimizing the exposure of uninvolved surrounding normal tissue. Spurred by multiple biological and technological advances, BT application has experienced substantial alteration over the past few decades. The procedure of I-125 radioactive seed implantation evolved from ultrasound guidance to computed tomography guidance. Compellingly, the creative introduction of 3D-printed individual templates, BT treatment planning systems, and artificial intelligence navigator systems remarkably increased the accuracy of I-125 BT and individualized I-125 ablative radiotherapy. Of note, utilizing I-125 to treat carcinoma in hollow cavity organs was enabled by the utility of self-expandable metal stents (SEMSs). Initially, I-125 BT was only used in the treatment of rare tumors. However, an increasing number of clinical trials upheld the efficacy and safety of I-125 BT in almost all tumors. Therefore, this study aims to summarize the recent advances of I-125 BT in cancer therapy, which cover experimental research to clinical investigations, including the development of novel techniques. This review also raises unanswered questions that may prompt future clinical trials and experimental work.

Abstract
Introduction Advances in multiparametric MRI (mpMRI) combining anatomic and functional imaging can accurately identify foci of adenocarcinoma within the prostate, offering the possibility of partial gland therapy. We performed tandem prospective pilot trials to investigate the feasibility of focal prostate SBRT (f-SBRT) based on correlating diagnostic mpMRI and biopsies with confirmatory pathology in treatment planning. Materials and Methods Patients with pathologic focal Gleason 6–7 disease and a corresponding PIRADS 4–5 lesion on mpMRI underwent targeted and comprehensive biopsies using MRI/ultrasound fusion under electromagnetic sensor navigation. After rigorous analysis for imaging biopsy concordance, five of 18 patients were eligible to proceed to f-SBRT. Chi-squared test was used for differences from expected outcomes, and concordance was estimated with binomial distribution theory and Wilson’s method. Results Six patients had Gleason 6 and 12 had Gleason 3 + 4 disease (mean PSA: 5.8 ng/ml, range: 2.2–8.4). Absolute concordance was 43.8% (95% CI: 0.20, 0.64). Patterns of discordance included additional sites of ipsilateral disease, bilateral disease, and negative target. Five were upstaged to a new NCCN risk category necessitating treatment escalation. The five patients with concordant pathology completed three-fraction f-SBRT with sparing of the surrounding normal structures (including contralateral neurovascular bundle), with no reported grade 2+ toxicities and favorable PSA responses (mean: 41% decrease). Conclusions On our pilot trials of f-SBRT planning using rigorous imaging and pathology concordance, image-guided confirmatory biopsies frequently revealed additional disease, suggesting the need for caution in partial-gland therapy. For truly focal disease, f-SBRT provided excellent dosimetry, minimal toxicity, and encouraging biochemical response. Clinical Trial Registration: www.clinicaltrials.gov, NCT02681614; NCT02163317.

Transperineal prostate biopsy identifies locations of clinically significant prostate cancer in men considering focal therapy with PI‐RADS 3–5 regions of interest. BJUI COMPASS 2021; 2:395-401. [PMID: 35474703 PMCID: PMC8988820 DOI: 10.1002/bco2.111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 09/08/2021] [Indexed: 11/18/2022] Open
Abstract
Objectives To determine the benefit of performing transperineal prostate mapping biopsy (TPMB) following multiparametric magnetic resonance imaging (mpMRI) to increase the identification of clinically significant prostate cancer (csPCa) with Gleason grade group (GG) ≥ 2 and their locations outside of the PI‐RADS v2 3–5 category lesions. Methods mpMRI was performed in 80 men prior TPMB from two institutions. The mpMRI was considered clinically significant (csMRI) if it contained one or more PI‐RADS 3–5 category lesion. mpMRI findings were compared against csPCa diagnosed by TPMB, performed between 16 November 2010, and 13 September 2019, for the entire gland, both lobes and to the right and left anterior and right and left posterior quadrants (RA, LA, RP and LP). Sensitivity, specificity, positive and negative predictive values (PPV, NPV), accuracy and the area under curve (AUC) were determined. Thirteen men also underwent radical prostatectomy and had comparison of TPMB pathology to prostatectomy specimen grading. Results TPMB was positive in 60/80 (75%) of which 32 (53.3%) were csPCa. csPCa was present in the RA in 9 (11.3%), LA in 11 (13.8%), RP in 25 (31.3%) and LP in 27 (33.8%) and involved 1 quadrant in 7 (21.9%), 2 quadrants in 12 (37.5%), 3 quadrants in 11 (34.4%) and all 4 quadrants in 2 (6.3%) patients; 57/80 (71.3%) men had a mpMRIs with lesions designated as PI‐RADS 3 in 24 (30%), 4 in 25 (31.3%) and 5 in 8 (10%). A csMRI was present in the RA in 7 (8.8%), LA in 8 (10%), RP in 31 (38.8%) and in the LP in 29 (36.3%), which were limited to one quadrant in 39 (68.4%), 2 quadrants in 16 (28.1%), and 3 quadrants in 2 (3.5%). Sensitivity, specificity, PPV, and NPV were determined from the results of the TPMB and were for the entire gland 81.3%, 35.4%, 45.6% and 73.9%. There were 31 csMRIs involving the right posterior of the gland but only 25 csPCa by TPMB of which 12/31 (38.7%) were concordant for high grade disease. There were 29 men who have a csMRI in the left posterior quadrant, and 14 (48.3%) were concordant with csPCa from the TPMB. Conclusions MpMRI should be supplemented with TPMB to correctly identify the regions of the prostate that would require ablation in men considering focal therapy.

Abstract
Chimeric antigen receptor (CAR) T cell immunotherapy involves the genetic modification of the patient's own T cells so that they specifically recognize and destroy tumour cells. Considerable clinical success has been achieved using this technique in patients with lymphoid malignancies, but clinical studies that investigated treating solid tumours using this emerging technology have been disappointing. A number of developments might be able to increase the efficacy of CAR T cell therapy for treatment of prostate cancer, including improved trafficking to the tumour, techniques to overcome the immunosuppressive tumour microenvironment, as well as methods to enhance CAR T cell persistence, specificity and safety. Furthermore, CAR T cell therapy has the potential to be combined with other treatment modalities, such as androgen deprivation therapy, radiotherapy or chemotherapy, and could be applied as focal CAR T cell therapy for prostate cancer.

Abstract
Intractable late urinary toxicity is a serious complication after radiotherapy for patients with localized prostate cancer (LPC). We assessed clinical factors correlated with severe late urinary toxicity in LPC treated with curative image-guided intensity-modulated radiation therapy (IMRT). A total of 452 patients with LPC treated with IMRT between 2002 and 2016 were retrospectively analyzed. Among them, 432 patients received androgen deprivation therapy (ADT). The median total irradiated doses were 80 (range, 76-80) Gy. Each daily dose was 2 Gy per fraction. The median follow-up was 83 (range, 4-210) months. Late urinary toxicity was scored according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.03. Grade 3 late urinary toxicity was observed in 27 patients. No cases with grade ≥ 4 late urinary toxicity were observed. The 5-, 10-, and 12.5-year grade 3 late urinary toxicity-free survival rates were 97%, 91.8% and 88.1%, respectively. Age, risk classification, total irradiated dose, ADT duration, antithrombotic therapy (AT), cardiovascular disease, hypertension (HT), diabetes mellitus (DM), dyslipidemia (DL), prior transurethral resection of the prostate (TURP) and prior high-intensity focused ultrasound (HIFU) were investigated for correlations with grade 3 late urinary toxicity. In univariate analysis, AT and prior HIFU and no other studied factors, were correlated with grade 3 late urinary toxicity. AT and prior HIFU appear to be predictive of grade 3 late urinary toxicity. Patients with LPC with these relevant clinical factors should be carefully followed up by sharing detailed information with the urology department.

Abstract
Despite innovations in surgical technology and advancements in radiation therapy, radical treatments for clinically localized prostate cancer are associated with significant patient morbidity, including both urinary and sexual dysfunction. This has created a vital need for therapies and management strategies that provide an acceptable degree of oncologic efficacy while mitigating these undesirable side effects. Successful developments in screening approaches and advances in prostate imaging have allowed clinicians to identify, localize, and more precisely target early cancers. This has afforded urologists with an important opportunity to develop and employ focal ablation techniques that selectively destroy tumors while preserving the remainder of the gland, thus avoiding detrimental treatment effects to surrounding sensitive structures. A lack of high-level evidence supporting such an approach had previously hindered widespread adoption of focal treatments, but there are now numerous published clinical trials which have sought to establish benchmarks for safety and efficacy. As the clinical evidence supporting a potential role in prostate cancer treatment begins to accumulate, there has been a growing acceptance of focal therapy in the urologic oncology community. In this narrative review article, we describe the techniques, advantages, and side effect profiles of the most commonly utilized focal ablative techniques and analyze published clinical trial data supporting their evolving role in the prostate cancer treatment paradigm.

Abstract
Background We recently described a novel form of focal therapy for prostate cancer (CaP)—the precision prostatectomy. Here we report on the first 25 consecutive patients. Further, utilizing Surveillance Epidemiology and End Results (SEER)-registry data, we assess long-term oncological efficacies of various focal therapy techniques. Methods Men who met the criteria: (I) PSA ≤15 ng/mL, (II) stage ≤cT2, (III) dominant unilateral lesion with Gleason ≤4+3 with any number or percentage (%) of cores involved ipsilaterally on biopsy, (IV) no primary Gleason ≥4 contralaterally, and (V) preoperative erectile function score (IIEF-5/SHIM) of ≥17 with/without PDE-5i were included in this prospective, single-arm, IDEAL stage 2b study (December 2016 to July 2017). Safety of the technique, and intermediate-term urinary, sexual and oncological outcomes were studied. Descriptive statistics and Kaplan-Meier (KM) analysis were used to assess 12-month urinary continence (0–1 pad), 12-month sexual potency (SHIM ≥17), and 36-month freedom from clinically-significant CaP (grade group ≥2), radical treatment, metastatic disease and mortality. SEER-registry was queried to evaluate CaP-specific survival in patients undergoing hyperthermia, cryotherapy, or segmental prostatectomy. Results At study entry, the median (IQR) age, PSA and SHIM score were 56.5 (53.1–62.3) years, 4.2 (3.8–5.9) ng/mL and 23 [20–25], respectively. Only 1 patient met the Epstein criteria for active surveillance. All patients were followed for a minimum of 2 years. At 12 months, from a functional standpoint, all patients were continent. Twenty-three (92%) patients were potent at 12 months. From an oncological standpoint, at 36 months, the KM analysis (95% CI) demonstrated a 96.2% (92.9–98.7) rate of freedom from clinically-significant CaP and a 92.7% (88.9–97.2) rate of freedom from radical treatment. All patients were alive and free of metastatic disease at the latest follow-up. Analysis of the SEER-registry data demonstrated 10-year CaP-specific survival rates of 91.6% to 97.7% among the 3 studied modalities, P=0.298. Conclusions Precision prostatectomy is feasible, technically safe, and offers excellent postoperative functional results. At 36 months of follow-up, the oncological outcomes and secondary procedure rates appear to be at-par with the ablative forms of focal therapy.

Abstract
PURPOSE In-field prostate cancer (PCa) oligo-recurrence after pelvic radiotherapy is a challenging situation for which metastasis-directed treatments may be beneficial, but options for focal therapies are scarce. METHODS We retrospectively reviewed data for patients with three or less in-field oligo-recurrent nodal, bone and/or locally recurrent (prostate, seminal vesicles, or prostatic bed) PCa lesions after radiation therapy, identified with molecular imaging (PET and/or MRI) and treated by focal ablative therapy (cryotherapy or radiofrequency) at the Institut Bergonié between 2012 and 2020. Chosen endpoints were the post-procedure PSA response (partially defined as a >50% reduction, complete as a PSA <0.05 ng/ml), progression-free survival (PFS) defined as either a biochemical relapse (defined as a rise >25% of the Nadir and above 2 ng/ml), radiological relapse (on any imaging technique), decision of treatment modification (hormonotherapy initiation or line change) or death, and tolerance. RESULTS Forty-three patients were included. Diagnostic imaging was mostly 18F-Choline positron emission tomography/computerized tomography (PET/CT) (75.0%), prostate specific membrane antigen (PSMA) PET/CT (9.1%) or a combination of pelvic magnetic resonance imaging (MRI), CT, and 99 mTc-bone scintigraphy (11.4%). PSA response was observed in 41.9% patients (partial in 30.3%, complete in 11.6%). In the hormone-sensitive exclusive focal ablation group (n = 31), partial and complete PSA responses were 32.3 and 12.9% respectively. Early local control (absence of visible residual active target) on the post-procedure imaging was achieved with 87.5% success. After a median follow-up of 30 months (IQR 13.3-56.8), the median PFS was 9 months overall (95% CI, 6-17), and 17 months (95% CI, 11-NA) for PSA responders. Complications occurred in 11.4% patients, with only one grade IIIb Dindo-Clavien event (uretral stenosis requiring endoscopic uretrotomy). CONCLUSION In PCa patients showing in-field oligo-recurrence after pelvic radiotherapy, focal ablative treatment is a feasible option, possibly delaying a systemic treatment initiation or modification. These invasive strategies should preferably be performed in expert centers and discussed along other available focal strategies in multi-disciplinary meetings.

Abstract
INTRODUCTION Conventional cancer treatments such as radical surgery and systemic therapy targeting the organ or organ system might have side effects because of damage to the surrounding tissue. For this reason, there is a need for new instruments that focally treat cancer. AREAS COVERED This review provides a comprehensive overview of the patent literature on minimally and noninvasive focal therapy instruments to treat localized cancer. The medical section of the Google Patents database was scanned, and 128 patents on focal therapy instruments published in the last two decades (2000-2021) were retrieved and classified. The classification is based on the treatment target (cancer cell or network of cancer cells), treatment purpose (destroy the cancerous structure or disable its function), and treatment means (energy, matter, or a combination of both). EXPERT OPINION We found patents describing instruments for all groups, except for the instruments that destroy a cancer cell network structure by applying matter (e.g. particles) to the network. The description of the different treatment types may serve as a source of inspiration for new focal therapy instruments to treat localized cancer.

Unilateral lesion detected on preoperative multiparametric magnetic resonance imaging and MRI/US fusion-guided prostate biopsy is not an appropriate indication for focal therapy in prostate cancer. Urol Oncol 2021; 39:730.e17-730.e22. [PMID: 34175215 DOI: 10.1016/j.urolonc.2021.04.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 03/03/2021] [Accepted: 04/12/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE This study aimed to investigate if preoperative assessments of multiparametric magnetic resonance imaging (mpMRI) and Magnetic resonance imaging /ultrasound (MRI/US) fusion-guided prostate biopsy could be used to guide focal therapy for prostate cancer. MATERIALS AND METHODS A total of 101 prostate cancer patients undergoing radical prostatectomy were included. Preoperative findings included mpMRI and MRI/US fusion-guided prostate biopsy, while postoperative whole mount pathology was based on surgical specimen. RESULTS Of the 101 patients preoperatively diagnosed with a unilateral tumor, postoperative whole mount pathology showed 73.27% were bilateral tumors, and 71.62% of bilateral lesions were clinically significant. Comparison between preoperative and postoperative findings, the correct rate of preoperative mpMRI on the lesion side (left or right) was only 20.79%. As for the Gleason score, the correct rate of preoperative MRI/US fusion-guided prostate pathology was 67.33%. Judging from postoperative whole mount pathology, 47.52% of patients had a unilateral clinically significant tumor, which is an indication for focal therapy. CONCLUSION Preoperative examinations of mpMRI and MRI/US fusion-guided prostate biopsy cannot be used to guide focal therapy for prostate cancer.

Urol Oncol 2021; 39:830.e9-830.e16. [PMID: 34144892 DOI: 10.1016/j.urolonc.2021.04.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 03/03/2021] [Accepted: 04/12/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVES MR-guided transurethral ultrasound ablation (TULSA) has primarily been investigated for whole-gland prostate ablation, even though the technology is also well-suited for partial gland treatment. The objectives were to perform a clinical service evaluation of partial to whole-gland TULSA for patients with localized prostate cancer (CaP). TULSA was also evaluated as a combined therapy for a subset of patients presenting with both cancer and concurrent benign prostate hyperplasia (BPH). SUBJECTS AND METHODS This retrospective, consecutive clinical service evaluation included men with histopathologically-confirmed CaP who underwent TULSA either as primary or salvage treatment. The planned ablation was dependent on the individual tumor characteristics, concurrent BPH and patient preferences. The Clavien-Dindo classification was used to record complications. Surgeon-assessed functional outcomes were reported. Early treatment success was defined by negative multiparametric MRI (mpMRI) and lack of prostate specific antigen (PSA) recurrence. RESULTS Fifty-two consecutive patients (47 treatment-naïve and 5 salvage) were included, with median follow-up of sixteen months and a max of thirty-six months. Baseline median (IQR) age and PSA were 67 years (63-76) and 8.0 ng/ml (5.2-13), respectively. Two Grade IIIa adverse events were observed, with no bowel-related complications. For urinary continence outcomes, 1 patient worsened to 1 pad per day. All patients who were previously potent maintained erectile potency. Of the patient subgroup also seeking treatment for BPH, 83% reported symptom improvement. Median (IQR) PSA nadir after primary treatment was 1.1 ng/ml (0.5-2.1). Early treatment success was 88%. Nine patients underwent a single repeat TULSA. CONCLUSION Customized prostate ablation with TULSA offers flexible ablation according to patients' disease characteristics and treatment expectations, providing favorable safety and promising early MRI and PSA results. TULSA is a feasible combination therapy for patients with both cancer and concurrent BPH.

Immunohistochemistry for Prostate Biopsy-Impact on Histological Prostate Cancer Diagnoses and Clinical Decision Making. ACTA ACUST UNITED AC 2021; 28:2123-2133. [PMID: 34207594 PMCID: PMC8293248 DOI: 10.3390/curroncol28030197] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 05/15/2021] [Accepted: 06/07/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND To test the value of immunohistochemistry (IHC) staining in prostate biopsies for changes in biopsy results and its impact on treatment decision-making. METHODS Between January 2017-June 2020, all patients undergoing prostate biopsies were identified and evaluated regarding additional IHC staining for diagnostic purpose. Final pathologic results after radical prostatectomy (RP) were analyzed regarding the effect of IHC at biopsy. RESULTS Of 606 biopsies, 350 (58.7%) received additional IHC staining. Of those, prostate cancer (PCa) was found in 208 patients (59.4%); while in 142 patients (40.6%), PCa could be ruled out through IHC. IHC patients harbored significantly more often Gleason 6 in biopsy (p < 0.01) and less suspicious baseline characteristics than patients without IHC. Of 185 patients with positive IHC and PCa detection, IHC led to a change in biopsy results in 81 (43.8%) patients. Of these patients with changes in biopsy results due to IHC, 42 (51.9%) underwent RP with 59.5% harboring ≥pT3 and/or Gleason 7-10. CONCLUSIONS Patients with IHC stains had less suspicious characteristics than patients without IHC. Moreover, in patients with positive IHC and PCa detection, a change in biopsy results was observed in >40%. Patients with changes in biopsy results partly underwent RP, in which 60% harbored significant PCa.

Chao B, Lepor H. 5-Year Outcomes Following Focal Laser Ablation of Prostate Cancer. Urology 2021; 155:124-129. [PMID: 34090887 DOI: 10.1016/j.urology.2021.03.054] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/29/2021] [Accepted: 03/31/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To characterize the oncologic outcomes 5 years following focal laser ablation (FLA) of localized prostate cancer. METHODS 36 men underwent in-bore FLA of prostate cancer at our institution between 2013 and 2015. Follow up included digital rectal examination and PSA testing, multiparametric MRI, and MR-guided biopsies. The primary outcome of interest was failure-free survival (FFS), defined as avoidance of salvage whole gland treatment, systemic therapy, metastasis, or death from prostate cancer. RESULTS Of the 36 men enrolled, 6 were ultimately lost to follow-up. Of the remaining 30, 25 (83%) have remained free from failure over a median follow-up of 71 months'. Among these patients, 10 (40%) developed in-field recurrence, with 9 undergoing salvage partial gland ablation with FLA, cryotherapy, or high-intensity focused ultrasound. Five patients underwent salvage whole gland or systemic treatment and were thus considered to have failed treatment. Two patients developed metastatic disease, and after receiving radiation and ADT, both currently have undetectable PSA levels. No patients in the cohort died from prostate cancer. Limitations include a small study cohort and lack of standardized surveillance protocols 2 years after treatment. CONCLUSION FLA for select cases of prostate cancer provides high rates of FFS, defined as freedom from whole gland or systemic treatment, metastasis, or death from prostate cancer. However, in- or out-of-field recurrence is common and often necessitates salvage ablation.

Perceptions of partial gland ablation for prostate cancer among men on active surveillance: A qualitative study. BMJ SURGERY, INTERVENTIONS, & HEALTH TECHNOLOGIES 2021; 3:e000068. [PMID: 34458727 PMCID: PMC8388575 DOI: 10.1136/bmjsit-2020-000068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 02/18/2021] [Accepted: 04/05/2021] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVES – Partial gland ablation (PGA) therapy is an emerging treatment modality that targets specific areas of biopsy proven prostate cancer (PCa) to minimize treatment-related morbidity by sparing benign prostate. This qualitative study aims to explore and characterize perceptions and attitudes toward PGA in men with very-low-risk, low-risk, and favorable intermediate-risk PCa on active surveillance (AS). DESIGN – 92 men diagnosed with very-low-risk, low-risk, and favorable intermediate-risk PCa on AS were invited to participate in semi-structured telephone interviews on PGA. SETTING – Single tertiary care center located in New York City. PARTICIPANTS – 20 men with very-low-risk, low-risk, and favorable intermediate-risk PCa on AS participated in the interviews. MAIN OUTCOME MEASURES – Emerging themes on perceptions and attitudes toward PGA were developed from transcripts inductively coded and analyzed under standardized methodology. RESULTS – Four themes were derived from twenty interviews that represent the primary considerations in treatment decision-making: (1) the feeling of psychological safety associated with low-risk disease; (2) preference for minimally invasive treatments; (3) the central role of the physician; (4) and the pursuit of treatment options that align with disease severity. Eleven men (55%) expressed interest in pursuing PGA only if their cancer were to progress, while 9 men (45%) expressed interest at the current moment. CONCLUSIONS – Though an emerging treatment modality, patients were broadly accepting of PGA for PCa with men primarily debating the risks versus benefits of proactively treating low-risk disease. Additional research on men's preferences and attitudes toward PGA will further guide counseling and shared decision-making for PGA.

Long-term Outcomes of Focal Cryotherapy for Low- to Intermediate-risk Prostate Cancer: Results and Matched Pair Analysis with Active Surveillance. Eur Urol Focus 2021; 8:701-709. [PMID: 33926838 DOI: 10.1016/j.euf.2021.04.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/13/2021] [Accepted: 04/08/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND To date, only one trial compared focal therapy and active surveillance (AS) for low-risk prostate cancer (PCa). In addition, long-term outcomes of focal cryotherapy (FC) are lacking. OBJECTIVE Our aim was to evaluate long-term outcomes of FC and compare them with AS. DESIGN, SETTING, AND PARTICIPANTS We included two prospective series of 121 (FC) and 459 (AS) consecutive patients (2008-2018) for low- to intermediate-risk PCa. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Study outcomes were radical therapy-free or androgen deprivation therapy (ADT)-free, any treatment-free, metastasis-free, and overall survival. A matched pair analysis was performed using seven covariates. RESULTS AND LIMITATIONS The median FC follow-up was 85 mo (interquartile range 58-104); 92 (76%) men had International Society of Urological Pathology (ISUP) grade 1. Among matched variables, no significant differences were present except for cT stage and year of entry (both p < 0.01). Ten-year radical therapy-free or ADT-free, any treatment-free, metastasis-free, and overall survival were 51%, 40.2%, 93.9%, and 97%, respectively for FC. No differences were noted with AS (all p > 0.05), with the exception of time to radical therapy, time to radical therapy and ADT, and time to any treatment, all being shorter for AS (all p < 0.01). Freedom from radical treatment or ADT was higher for FC (AS 10 yr 39.3%; p = 0.04). Complications were relatively rare (26.5%) and mainly of low grade (Clavien >2, n = 3); three men developed incontinence (p = 0.0814), while both International Index of Erectile Function 5 and International Prostate Symptom Score scores increased (p = 0.0287 and p = 0.0165, respectively). Limitations include absence of randomization. CONCLUSIONS At an early long-term follow-up, FC in the context of mainly low-risk PCa is safe and increases time to radical therapy but does not provide meaningful oncological advantages compared with AS. PATIENT SUMMARY We compared focal cryotherapy with active surveillance mainly for low-risk prostate cancer. Focal cryotherapy, despite having fewer complications, did not yield meaningful advantages over active surveillance at 10 yr. Active surveillance should be preferred to focal cryotherapy for these patients.
