Researchers from Helmholtz Munich, the Technical University of Munich (TUM), and the Medical University of Vienna have announced a new advanced endoscopy technique called “O2E.” This technology allows clinics to detect cancerous lesions in the esophagus with unprecedented precision.

Published in Nature Biomedical Engineering, the study revealed that this innovative endoscopy method can identify even the smallest pathological tissue changes. This significantly improves early detection and diagnosis of esophageal cancer.

Esophageal cancer is among the deadliest cancers. When diagnosed at an advanced stage, survival rates are only about 10%. However, early detection increases survival to around 90%. The new O2E technology could play a crucial role in identifying early tissue changes.

O2E combines two imaging techniques into one endoscopy technology. Optical coherence tomography (OCT) captures detailed tissue structures. Optoacoustic imaging (OPAM) uses light pulses and ultrasound to visualize tiny blood vessels deep in the tissue.

By merging these methods, the system generates high-resolution 3D images of esophageal tissue structure and function. Both sensors are integrated into an endoscopy capsule that scans tissue in a full 360-degree angle.

Prof. Vasilis Ntziachristos, Director at Helmholtz Munich’s Institute of Biological and Medical Imaging and Chair at TUM, reported that the dual imaging system reveals microscopic structural changes and subtle microvascular alterations beneath the mucosal surface. These features were previously undetectable.

In a pilot study, researchers examined animal esophagus tissue and samples from patients with Barrett’s esophagus, a precursor to esophageal cancer. They successfully distinguished healthy tissue from abnormal cellular changes, precancerous stages, and malignant tumors.

Initial proof-of-principle tests were conducted on a volunteer’s inner lip, which shares similar tissue characteristics with the esophagus, further confirming the technology’s potential in healthcare.

• The O2E technology merges OCT and optoacoustic imaging for detailed cancer detection.
• It offers high-resolution 3D images via a 360-degree scanning endoscopy capsule.
• Early detection using O2E could greatly improve esophageal cancer survival rates.

This breakthrough could transform esophageal cancer diagnosis and improve patient outcomes worldwide.
