New Research Supports Light-based Detection for Early Mesothelioma, Reports Surviving Mesothelioma

Japanese doctors say a technique that measures fluorescent light emissions from cells can be used to help distinguish tiny mesothelioma tumors.

Light-based Diagnosis for Early Mesothelioma

Autofluorescence Identified Mesothelioma Tumors

The color spectrum shift was observed in all tumors located on the pleural surface.

Cancer researchers in Hokkaido, Japan have successfully used an autofluorescence imaging system to identify mesothelioma and other pleural cancers during video-assisted thoracic surgery. Click here to read Surviving Mesothelioma’s new article on the findings.

Scientists at Asahikawa Medical University used a special blue light to measure fluorescent light emitted by cells. Pleural cancers like mesothelioma and metastatic lung cancer could be identified by their shift from healthy green to red-violet light emissions.

“The color spectrum shift was observed in all tumors located on the pleural surface but not in cases with pleural fibrous disease,” reports lead study author Masahiro Kitada in the Annals of Thoracic and Cardiovascular Surgery.

The study concluded that this method for identifying even tiny mesothelioma or lung cancer tumors could be useful for planning treatment strategies and surgery.

“One of the aspects of mesothelioma that makes it so deadly is the fact that it is so hard to detect in its early, more treatable stages,” says Surviving Mesothelioma Managing Editor Alex Strauss. “The idea that this photodynamic technique could help find even very small tumors is encouraging.”
