Breath test proposed for colon cancer screening

Study supports value of breath testing as a potential cancer screening tool

Dec 5, 2012 CBC

Breath tests have the potential to identify people with colorectal cancer, a small study suggests.

Researchers know that cancer tissue has a different metabolism compared with healthy cells that produce substances that can be detected in the breath non-invasively.

Breath analysis is already used to diagnose benign gastrointestinal disorders such asH. pylori infectionor lactose intolerance.

To test the method for colorectal cancer, researchers in Italy collected breath samples from 37 people with colorectal cancer and 41 people without the disease and used a statistical model to compare the chemical fingerprints in the exhaled samples.

"The present findings support the value of breath testing as a screening tool," Dr. Donato Altomare, of the department of emergency and organ transplantation at the University Aldo Moro of Bari in Italy, and co authors concluded in Wednesday's issue of the British Journal of Surgery.

People with colorectal cancer showed a different pattern for 15 of 58 volatile organic compounds, their study suggested.

The researchers said their goal is to improve the diagnostic accuracy of blood and stool tests or virtual colonoscopy forearly detectionof colorectal cancer and polyps.

The model misclassified five out of 37 patients and seven of 41 controls.

and I would love some help in figuring out how many false positives would be of 34,640 people tested
