Hossam Haick, PhD, of the department of Chemical Engineering and Russell Berrie Nanotechnology Institute, Technion- Israel Institute of Technology in Haifa, Israel announced that they have developed a breath test for the detection of stomach cancer and precancerous lesions. The announcement was noted in Medpage Today, an online journal, and published in the Journal “Gut.” “Volatile organic compound marker detection based nonarray technology allows gastric cancer to be detected with high accuracy in a Caucasian population. The technology allows high-risk precancerous lesions to be detected via exhaled breath “even with the confounding factors of patient smoking, Heliobacter Pylori infection and alcohol use. It is extremely difficult to diagnose gastric cancer before an individual is symptomatic. Except for Japan and South Korea, almost no health care systems screen for the presence of gastric cancer in their population. These countries traditionally have very high rates of gastric cancer so they screen for it routinely in adults using upper endoscopy and imaging techniques.
“The future of cancer prevention relies on timely recognition and surveillance of precancerous lesions as well as early detection of the cancer, making higher survival rates and lower healthcare costs per patient achievable,” says Dr. Haick. “Detection of precancerous lesions would allow surveillance to be performed, making early detection of the transformation to cancer possible.” The publication in “Gut” looked at precancerous lesions but the goal is to additionally use this technique to follow a diseases progress and detect potential relapses.
At the current time this test is experimental, but large scale human testing is now underway in Europe. Hopefully a commercially available product will be released in the next few years.
