The use of histotripsy as intratumoral immunotherapy beyond tissue ablation—the rationale for exploring the immune effects of histotripsy

International Journal of Hyperthermia, 2023
Mechanical high-intensity focused ultrasound (M-HIFU), which includes histotripsy, is a non-ionizing, non-thermal ablation technology that can be delivered by noninvasive methods. Because acoustic cavitation is the primary mechanism of tissue disruption,

Mapping the lineage of prostate tissue ablation medical device predicates for focal therapy of prostate cancer approved via the FDA 510(k) clearance pathway

Surgical Practice, EarlyView.
Abstract Objective Medical devices are reviewed by the US Food and Drug Administration (FDA) for safety and effectiveness. Class II devices can receive 510(k) clearance if they are “substantially equivalent” to an existing predicate device. This process can be repeated iteratively, leading to a lineage of predicates for newly cleared devices.

High-intensity focused ultrasound ablation to increase tumor-specific lymphocytes in prostate cancer

Translational Oncology
Treatment options for localized prostate cancer have been expanded by FDA-approval of High-Intensity Focused Ultrasound (HIFU). Prostate cancer typically has few tumor-infiltrating lymphocytes, which are crucial for antitumor immunity.

Magnetic resonance guided high intensity focused ultrasound for uterine fibroids and adenomyosis has no effect on ovarian reserve

International Journal of Hyperthermia, 2023
Introduction Uterine fibroids are the most common benign tumors in healthy women. High Intensity Focused Ultrasound (HIFU) is a modern, noninvasive thermal ablation method for treating uterine fibroids. There is increasing evidence that ultrasound guided

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

AI-powered ultrasonic thermometry for HIFU therapy in deep organ

Ultrasonics Sonochemistry
High-intensity focused ultrasound (HIFU) is considered as an important non-invasive way for tumor ablation in deep organs. However, accurate real-time monitoring of the temperature field within HIFU focal area remains a challenge.

Magnetic resonance‐guided high‐intensity focused ultrasound (MR‐HIFU) therapy of uterine fibroids effectively reduces both bleeding and bulk symptoms—A prospective single‐center 12‐month follow‐up study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Magnetic resonance‐guided high‐intensity focused ultrasound (MR‐HIFU) resulted in significant symptom reduction and improved quality of life in patients with symptomatic uterine fibroids and either bleeding or bulk symptoms. When successful, MR‐HIFU provides effective and rapid symptom relief for both symptom types.
