New Ultrasound-Laser combo could spare rectal cancer patients from unnecessary surgery
NCT ID NCT04339374
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new device that combines ultrasound with photoacoustic imaging to look at rectal tumors. The goal is to see if it can more accurately tell whether a patient's cancer has completely responded to pre-surgery treatment. If it works, doctors could avoid operating on patients who are already cancer-free. The trial will enroll 90 adults with rectal cancer who are scheduled for surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Photoacoustic imaging device
What this could lead to
If successful, this imaging tool could help doctors more accurately determine which rectal cancer patients have responded completely to treatment, sparing them from unnecessary surgery.
What could go wrong
This is an early-stage feasibility study with only 90 participants. The device may not prove accurate enough in practice, and results may not apply to all rectal cancer patients.
