Transperineal Targeted Microwave Ablation (TMA) of localized prostate cancer guided by MRI-Ultrasound fusion and organ-based tracking: a pilot study. Prostate Cancer Prostatic Dis 2023; 26:736-742. [PMID: 35835844 DOI: 10.1038/s41391-022-00577-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 06/28/2022] [Accepted: 07/04/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND To investigate the efficacy of transperineal targeted microwave ablation (TMA) in treating localized prostate cancer (PCa). METHODS This is a single-centre prospective phase 2 trial recruiting men with low to intermediate-risk localized PCa to undergo transperineal TMA. TMA was performed with MRI-Ultrasound fusion guidance and organ-based tracking. A per-protocol 6-month MRI and biopsy were performed for all patients. The primary outcome was any cancer detected on biopsy of each ablated area. Secondary outcomes included per-patient analysis of positive biopsy, complications, urinary symptom score, erectile function and quality of life (QOL) scores. RESULTS In the first 15 men, 23 areas were being treated. The median age was 70 years, number of TMA ablations were 5 (range 2-8), and the total ablation time and operating time was 22 (IQR 14-28) and 75 (IQR 65-85) minutes, respectively. PSA level dropped from a median of 7.7 to 2.4 ng/mL. For the primary outcome, 91.3% (21/23) ablated area had no cancer in 6-month biopsy. In per-patient analysis, 33.3% (5/15) had in or out-of-field positive biopsy at 6 months. Among these five cases, four of them were amenable to active surveillance and 1 (6.7%) case with out-of-field ISUP grade group 2 cancer received radiotherapy. The urinary symptoms, uroflowmetry, erectile function, and QOL scores had no significant difference at 6 months. One patient (out of five patients with normal erection) in the cohort complained of significant worsening of erectile function after TMA. Grade 1 complications including hematuria (33.3%), dysuria (6.7%), and perineal discomfort (13.4%) were observed. CONCLUSIONS In this first pilot study, transperineal TMA guided by MRI-Ultrasound fusion guidance and organ-based tracking was shown to be effective, safe, and easily applicable in men with localized PCa.

Prostate Int 2023; 11:134-138. [PMID: 37745903 PMCID: PMC10513903 DOI: 10.1016/j.prnil.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 09/10/2022] [Accepted: 12/02/2022] [Indexed: 12/23/2022] Open
Abstract
Background We compared the clinical outcomes of robot-assisted radical prostatectomy (RARP) and partial gland ablation (PGA) using high-intensity focused ultrasound (HIFU) in localized prostate cancer. Methods We analyzed 3,859 patients who had undergone RARP and PGA using HIFU. According to the propensity score for each treatment, 137 patients after PGA were matched to 3,722 patients after RARP at a 1:4 ratio using the nearest neighbor method. Results The matched cohort comprised 685 subjects (RARP, 548; PGA, 137), with a median follow-up period of 22 months. Treatment failures were identified in 13.9% and 9.1% of patients in the PGA and RARP groups, respectively, after a median follow-up of 36 months postoperatively. Kaplan-Meier analyses revealed significantly longer failure-free (P < 0.001) and salvage-free survival (P = 0.003) in the RARP group than in the PGA group. There was no significant difference in the postoperative urinary symptom score (P = 0.748), but the postoperative erectile function score was significantly higher in the PGA group (P < 0.001). The rate of urinary incontinence (any pad) was significantly lower in the PGA group than that in the RARP group (P < 0.001). Postoperative complications were more frequent in the PGA group (P = 0.003); however, there was no significant difference in high-grade complications (≥3) (P = 0.467). Conclusion PGA using HIFU showed statistically inferior oncological outcomes compared with RARP for failure-free survival and salvage-free survival. However, functional outcomes regarding postoperative incontinence and erectile dysfunction were more favorable in the PGA group.

Abstract
Background To demonstrate the clinical usefulness of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) computerized tomography (CT) for irreversible electroporation (IRE) in prostate cancer patients. Methods From January to May 2021, 17 men were diagnosed with localized prostate cancer through preoperative mpMRI and [18F] florastamin PSMA PET-CT imaging, followed by transperineal MRI-ultrasound fusion-guided biopsy. The patients underwent IRE focal therapy at the target lesions under general anesthesia. To evaluate the treatment outcome, serum prostate-specific antigen (PSA) levels were followed up in the 1st, 3rd, 6th, 9th, 12th months, and mpMRI was taken in the 1st and 12th months, followed by MR fusion biopsy in the 12th month post-IRE. Results The mean age of the patients was 66.1 ± 9.3 with a median PSA of 7.5 ng/ml. After the treatment, PSA nadir was 4.06 ± 3.4, and 11 (64.7%) achieved decline of PSA more than 50% from the baseline. Rate of negative biopsy for prostate cancer is 88% (15/17) at 12 months MR fusion biopsy after the IRE treatment. Among the relapsed cases, 1 (6.9%) patient recurred at margin of treated area, and 1 (6.9%) patient was from outfield recurrence. When excluding initial four patients, none of the patients had cancer recur. Conclusions When treating with IRE focal therapy, PSMA-PET CT is a potentially valuable diagnostic approach for localizing prostate cancer; it supports the detection of lesions with conventional mpMRI, enabling to perform the procedure more completely.

Abstract
Thermal partial-gland ablation (TPGA) is a promising treatment option for patients with prostate cancer (PCa) that has an excellent side-effect profile. However, the literature on TPGA in high-risk PCa is not robust enough to discount the risk of undertreatment and understaging in this population. Future studies, especially with incorporation of advanced imaging to better select patients, are necessary to understand the safety and efficacy of TPGA in high-risk disease.

Abstract
Focal therapy (FT) has emerged as a potential treatment for localized prostate cancer (PCa) with encouraging functional outcomes. According to the compelling evidence based on meta-analyses and recent trials, erectile function (EF) is mostly retained at 6 and 12 months after FT when compared to baseline. These findings are consistent across different energy sources reported to date. However, overall, quality of life, including impotence, was not the endpoint for most studies. Additionally, impotency has not been consistently reported in most of the recent literature. Furthermore, confounding factors such as baseline potency and usage of phosphodiesterase 5 inhibitors (PDE5-I) were also frequently undisclosed. Long-term functional outcomes are awaited. To fully comprehend how FT affects EF, more extensive long-term randomized clinical trials using EF as a primary outcome are needed.

Abstract
PURPOSE OF REVIEW Minimal invasive procedures, including targeted biopsy (TB) and focal therapy (FT), are increasingly used in diagnosis and treatment of localized prostate cancer. Here, we review the current role of these procedures, from a perspective of an interventional radiologist. RECENT FINDINGS TB is an established part of current guidelines for diagnosis of PCa. Several modalities of FT are gaining prevalence in recent years, as a tissue-preserving alternative for definitive treatment of localized PCa. FT is currently at early research stages, offered to selected patients in clinical trials settings. TB and FT are minimally invasive procedures used by multidisciplinary teams for diagnosis and treatment of localized PCa.
