Conclusions: Early evidence suggested the partial-gland HIFU was safer than whole-gland HIFU, and they had similar oncological outcomes. More prospective randomized controlled trials of whole-gland and partial-gland HIFU for PCa was needed.

CONCLUSION: Large-volume MRgHIFU-mediated HT was successfully implemented and characterized in a porcine model in deep and superficial targets in vivo with heating distributions modifiable by user-definable parameters. PMID: 33003967 [PubMed - in process]

CONCLUSION: The current PFOB-FTAC micro-droplet sonosensitizers provided a large and sustained enhancement of the HIFU thermal deposition at the focal area, suggesting solutions for less technological constraints, lower risk for the near-/far- field heating. We also report a suitable experimental model for other MRgHIFU studies. PMID: 32990101 [PubMed - in process]

This study assess the role of HIFU on genetic change intratumorally post-treatmentImmunotherapy promises unprecedented benefits to cancer patients. However, the majority of cancer types, including high-risk neuroblastoma remain immunologically unresponsive. High intensity focused ultrasound (HIFU) is a non-invasive technique that can mechanically fractionate tumors, transforming immunologically ‘‘cold’’ tumors into responsive ‘‘hot’’ tumors. We treated tumors with HIFU, and assessed systemic immune response using flow-cytometry, ELISA, and gene sequencing. In addition, we com...

Abstract INTRODUCTION: Some men who experience prostate cancer recurrence post-radiotherapy may be candidates for local salvage therapy, avoiding and delaying systemic treatments. Our aim was to assess the impact of clinical outcomes of adding salvage local treatment in prostate cancer patients who have failed radiation therapy. METHODS: Following radiation biochemical failure, salvage transperineal cryotherapy (sCT, n=186), transrectal high intensity focused ultrasound ablation (sHIFU, n=113) or no salvage treatment (NST, identified from the pan-Canadian Prostate Cancer Risk Stratification [ProCaRS] database...

Authors: Anand N, Klug E, Nirappel A, Solá-Del Valle D Abstract Cyclodestruction aims to reduce aqueous humor production through the coagulation or destruction of the ciliary body and has been an important treatment choice for glaucoma since the 1930s. The purpose of the current review is to highlight the evidence regarding the safety and efficacy of various cyclodestructive modalities, emphasizing peer-reviewed articles from the last 20 years and the most common variants of these procedures. The review focuses primarily on the two most common variants of transscleral cyclophotocoagulation (TS-CPC), con...
