Summary

This study tests a device called histotripsy, which uses focused ultrasound to break up tumors without cutting the skin. It is for people with abdominal tumors that cannot be surgically removed and are causing symptoms like pain. The goal is to see if the treatment improves quality of life and reduces pain, while monitoring safety. The trial will enroll 30 participants at a single hospital in Taiwan.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Histotripsy (non-invasive focused ultrasound device)
What this could lead to: If successful, this could offer a needle-free, non-invasive option to shrink tumors and ease pain or discomfort for people with inoperable abdominal tumors.
What could go wrong: This is a small, early-stage study (30 people) with no control group. The device is not yet approved in Taiwan, and long-term benefits or risks are still unknown.
