Breath Test Could Help Doctors Predict and Diagnose Stomach Cancer
Because stomach cancer rarely causes symptoms in its early stages, most diagnoses do not occur until later stages when the disease is less treatable.
Researchers at the Israel Institute of Technology have developed a testing method that hopes to detect stomach cancer earlier and even predict a patient’s future risk of the disease. The study, published in the journal Gut, used nanoarray analysis of a patient’s breath to detect tiny changes in compounds exhaled during respiration.
During the study, the researchers performed breath analysis on 484 individuals, of which 99 had already been diagnosed but not treated for stomach cancer. The breath samples were analyzed for presence of Helicobacter pylori, a bacterial infection and known risk factor for stomach cancer. The researchers were able to identify eight “breath-prints” that helped them identify patients with stomach cancer and those at low or high risk.
The nanoarray technique had 73 percent sensitivity, 98 percent specificity, and 92 percent accuracy. Scientists have also considered gas chromatography-mass spectrometry (GCMS) as a means of using a patient’s breath to test for stomach cancer. But GCMS is more expensive than nanoarray analysis, and the latter could prove a cost-effective, accurate alternative.
Stomach cancer affects mainly elderly people over the age of 65 and is more prevalent in men than women. According to the American Cancer Society, approximately 10,720 people will die from stomach cancer this year. Stomach cancer can progress rapidly and spread to other organs very quickly. If you or a loved one have been diagnosed with stomach cancer and can no longer work or earn a living you may be eligible for Social Security disability benefits.
