Kettering Health is expanding its oncology services by offering histotripsy, a non-invasive treatment that uses focused sound waves to destroy liver tumors without incisions or ionizing radiation. According to health system announcements, the technology provides a new option for patients with primary or metastatic liver cancers who may not qualify for traditional surgery.
How Histotripsy Targets Liver Tumors
Histotripsy relies on high-amplitude acoustic pulses to create micro-bubbles within targeted tissue. According to medical device data from developer HistoSonics and clinical overviews, the rapid expansion and collapse of these bubbles—a process known as acoustic cavitation—mechanically breaks down and liquefies tumor cells at the cellular level. The body’s natural immune system and waste clearance then absorb the cellular debris. Because the system uses ultrasound rather than thermal energy or ionizing radiation, physicians can treat tumors adjacent to critical structures like blood vessels and bile ducts with minimal risk of collateral damage.
Clinical Benefits and Patient Recovery
The procedure offers significant advantages in recovery time compared to open surgery or percutaneous ablation techniques. According to clinical trial findings published in peer-reviewed literature such as the Journal of Clinical Oncology, patients undergoing histotripsy typically experience shorter hospital stays and a reduced risk of infection because the technique leaves the skin unbroken. Furthermore, real-time visualization allows physicians to monitor the destruction of the targeted mass continuously during the procedure, ensuring precision without the use of ionizing radiation.
Integration into Kettering Health’s Oncology Network
Kettering Health’s adoption of the Edison Histotripsy system places the network among a select group of regional health systems offering the FDA-cleared technology. According to hospital statements, multidisciplinary tumor boards evaluate individual patient cases to determine eligibility, ensuring that histotripsy is integrated alongside standard-of-care options such as chemotherapy, embolization, and surgical resection.
Frequently Asked Questions
What types of liver tumors can be treated with histotripsy?
Physicians evaluate both primary liver cancers, such as hepatocellular carcinoma, and tumors that have metastasized to the liver from other parts of the body. Suitability depends on tumor size, location, and overall liver function.
Does histotripsy require general anesthesia?
Yes, patients typically receive general anesthesia during the procedure to ensure they remain completely still while the focused ultrasound waves target the precise treatment zone.
How does histotripsy differ from radiofrequency ablation?
While radiofrequency ablation uses heat to destroy cancer cells, histotripsy uses mechanical forces generated by acoustic cavitation. This eliminates the risk of thermal injury to nearby healthy tissues and major blood vessels.
