Introduction

Cancer care has undergone tremendous improvement over the years, and innovation continues to define patient care. Of these newfound innovations, histotripsy in particular is a revolutionary, non-invasive treatment using focused ultrasound to liquefy, forming liquid cancer cells so no mechanical cutting is required. This review addresses the technical aspects of histotripsy, its scientific background, clinical indications and the bright future it has in oncology.

What is Histotripsy? — Non-Invasive Tumor Treatment

Histotripsy is a new medical application involving the use of high-pressure pulsed ultrasound to mechanically fractionate and liquefy tissue via a process known as cavitation. Unlike traditional therapies which use heat or radiation, the histotripsy technique uses sound waves to form bubbles in the tumour. The formation and collapse of these bubbles produce mechanical forces that disintegrate the tumor tissue into acellular debris, which is eventually reabsorbed by the body.

Features of Histotripsy

• Solid: Concretely located and non-aggressive
• Other: Treatment does not occur within a patient’s body or the body itself..
• Non-Thermal: Does not have thermal so that the risks of wounds and lesions months or months and years scarring. Unlike traditional tumor ablation techniques that rely on heat to destroy cancer cells, histotripsy uses high-intensity ultrasound waves to mechanically break apart tissue. This non-thermal nature means there’s no risk of thermal injury to surrounding healthy tissues, which is a common side effect in heat-based treatments. By avoiding high temperatures, histotripsy protects critical structures such as blood vessels, nerves, and organs adjacent to the tumor, significantly lowering the risk of complications.
• Real-Time Imaging Guidance: Uses ultrasound imaging to locate and closely monitor the area of treatment during procedures. Histotripsy is guided by real-time ultrasound imaging, which allows the physician to precisely target the tumor and monitor the treatment as it occurs. This precision reduces the chances of damaging surrounding healthy tissues, which in turn limits the side effects typically associated with less accurate forms of tumor treatment, like radiation therapy. This means there is a much lower likelihood of unintended damage to healthy tissue that could result in unwanted side effects, such as organ dysfunction or nerve damage.
• Fewer Side Effects: Because it is so targeted, histotripsy usually causes fewer side effects than standard treatments. One of the major advantages of histotripsy over traditional cancer treatments such as surgery, radiation therapy, and other forms of thermal ablation (like radiofrequency ablation or microwave ablation) is its reduced side effects.

How It Works: The Science Behind Histotripsy

Acoustic cavitation is mainly responsible for the therapeutic mechanism of histotripsy. When directed the focused high intensity ultrasound waves to some tissue site, they will cause microbubbles formation within this tissue. The fast oscillation of these bubbles results in their violent implosion, thus producing local mechanical stresses which extents to cellular structures. Such a process simply melts the tissue in such a way that the body’s immune system is capable of readily removing the material.

Advantages Versus Conventional Ablation Methods

Conventional forms of tumor ablation including radiofrequency ablation (RFA) and microwave ablation (MWA) are based on heat-mediated tumor cell killing. However, these methods may lead to thermal damage of healthy tissues surrounding the tumor and are not applicable to tumors close to critical structures. Unlike with histotripsy, there are many benefits:

• Accuracy: The high precision with which ultrasound waves can be targeted makes sure no other tissue but the tumour is harmed.
• Safety: Non-thermal in nature, reducing the likelihood of damage to normal adjacent tissue.
• Speed: Less time will be required for procedures to be carried out and many patients will be able to go home the same day.

Clinical Scenario: Histotripsy for Liver Tumors

To date, histotripsy has been largely used to treat liver tumors—both primary liver cancers such as hepatocellular carcinoma and metastatic disease to the liver. This technique is especially advantageous in a patient who is not fit for conventional surgery, either because of location of the tumor, size of the tumor, or poor medical status.

FDA Clearance and Clinical Implementation

The U.S. Food and Drug Administration (FDA) cleared histotripsy to treat liver tumors in October 2023. This clearance was an important first, as histotripsy became the world’s first non-invasive, non-thermal ablation technology to achieve such a status.

• Some medical centers are already offering histotripsy treatments in their clinics following FDA clearance: University of Chicago Medicine: Adopted the Edison Histotripsy System, which uses robotic, focused ultrasound to zero in on and obliterate liver cancer tissue.
• University of Michigan Health: Presented non-surgical histotripsy as an alternative to patients with liver tumors, explaining its potential to shorten recovery periods and enhance patient outcomes.
• Addenbrooke’s Hospital, Cambridge, UK: Europe’s first hospital to introduce histotripsy as noninvasive liver cancer treatment option used its new technology to treat liver tumors without a scalpel.

Beyond the Liver and Other Potential Targets

The present intended use of histotripsy in clinics primarily lies in liver tumors, whereas investigations and clinical trials are in progress to use histotripsy in an ever-expanding list of cancers. Possible applications include the following:

• Kidney Cancer: Evaluate use of histotripsy for renal tumors, including patients with the history of poor renal function. Kidney cancer, also known as renal cancer, is a type of cancer that starts in the cells in the kidneys. The kidneys are a pair of vital organs situated on either side of the spine, below the ribcage. They work to filter waste and excess fluid from the blood, excreting these substances as urine. Kidney cancer can occur in various part of the kidney, but the most common type is renal cell carcinoma (RCC) that starts in the lining of the small tubes in the kidney. By the time symptoms develop with such performances, kidney cancer is usually quite advanced, thus early detection and awareness of the disease is important to have a good treatment results.
• Pancreatic Cancer: Investigating the potential for treating pancreatic tumors, historically a difficult region for anatomic reasons, with histotripsy. Pancreatic cancer is cancer in the pancreas, which is an organ positioned behind the stomach. The pancreas is vital to digestion because it produces digestive enzymes that help break down food, and it is authoritative in controlling blood sugar by secreting insulin. Pancreatic cancer usually starts in the cells lining the ducts of the pancreas, and is called pancreatic ductal adenocarcinoma (PDAC), the most common type of the disease. Unfortunately, the disease is frequently diagnosed in late stage, and is considered one of the most treatment-resistant cancers.
• Low Intensity Laser Lithotripsy/Surgery: Prostate: Prospects for histotripsy as a non or minimally invasive treatment for prostate tumors. Low Intensity Laser Lithotripsy (LILL) is a medical procedure that is employed in the treatment of kidney stones, gall stones, or other stones in the body. Lithotripsy is a technique that uses sound waves or laser to break down large stones, allowing them to be passed out of the body. High intensity laser lithotripsy has existed for years, but low intensity laser lithotripsy provides a low-energy with laser beams for the breaking of stones, and is a less aggressive and noninvasive. This technique is particularly useful for patients with very hard stones that cannot be removed with other, less invasive treatments or who do not desire open surgery or higher-energy laser treatments.
• Brain Tumors: Evaluating the potential use of histotripsy for the treatment of some types of brain tumors, using its precision targeting abilities. Brain tumors are out-of-the-ordinary growths of cells in the brain or the extended nervous system. They can be noncancerous (benign) or cancerous (malignant), and they may be found in the brain or come from other parts of the body (metastatic or secondary tumors). Brain tumors have a relatively low incidence but are of great concern because of the very important functions handled by the brain, and because of the limited space in the skull. They cause a disruption in normal brain functioning and, depending on the tumor’s growth rate and location, can present a number of different symptoms.

These studies were exploratory to expand the potential clinical applications of histotripsy and to bring hope to cancer patients from different cancer types.

Future of Histotripsy — Challenges and Opportunities

Although promising, histotripsy still encounters several obstacles before it can be used extensively:

• Technical Limitations: The requirement of specialized equipment and expertise may constrain the availability, particularly in resource-deprived environments.
• Long-Term Efficacy Studies: Despite the initial promising results, more studies to determine the long-term efficacy and survival advantage of histotripsy are needed.
• Cost: This may have cost implications; same could be applicable in case of histotripsy as the advanced technology and infrastructure required for its performance would definitely increase the cost of treatment.
