Physicians have performed the first endoscopic ultrasound-guided microwave ablation (EUS-MWA) for pancreatic cancer in the United States, introducing a new minimally invasive treatment option. Pancreatic cancer is one of the hardest cancers to treat because the pancreas lies deep in the abdomen, and only about 10–15% of patients are eligible for surgery. This new approach may offer hope to patients who cannot undergo surgical tumor removal.
The procedure uses an endoscope equipped with high-resolution ultrasound to locate the tumor inside the pancreas. Once the tumor is identified, doctors deliver microwave energy directly into the cancer tissue. The heat produced by the microwave energy destroys cancer cells in a targeted way. Because the treatment is performed through an endoscope rather than open surgery, it does not require any external incisions. The procedure is typically done on an outpatient basis, allowing most patients to go home the same day and recover faster than with traditional surgery.
Doctors say the technique allows them to see the tumor in real time, improving the precision of treatment. Researchers also believe this type of ablation could alter the tumor environment, potentially helping chemotherapy and immunotherapy work more effectively. With pancreatic cancer survival rates still low, the new method may provide an important option for patients with advanced disease or those unable to undergo surgery while helping maintain quality of life.
