Gastric Cancer Detection Through Breath Test

During this time to make the diagnosis of gastric cancer is very difficult, but in 2011, the British Journal of Cancer reported how a nanosensor "nose" developed by researcher from Israel and China who led by Hossam Haick, a professor in the Department of Chemical Engineering and Russell Berrie Nanotechnology Institute, at Technion and his team successfully distinguished patients with head and neck or lung cancer from healthy controls by analyzing patterns of molecules in their exhaled breath.

For this latest pilot study, the researchers used nanomaterial-based sensors to analyze breath samples from 130 patients who had undergone endoscopy, some with biopsy. 37 of the patients had been diagnosed with stomach cancer, 32 had ulcers, and 61 had less severe stomach complaints.

Breath tests performed by a nanomaterial sensors to analyze chemical substances released from respiration. Unique chemicals that cause exhaled breath may indicate the development of gastric cancer. So far, this method is the most simple but accurate. If approved to be used widely, this method would be a big step for the medical world as it can detect more accurately gastric cancer early on.

Breath test with a nanomaterial containing microscopic sensors to find biomarkers particles from the air that remove it from the breath. This breath test method called Discriminant Factor Analysis (DFA) pattern recognition. Detection of chemical patterns with breath test can distinguish bad breath caused by food that has just eaten or tobacco consumption. During this time, gastric cancer is usually detected only when it has reached an advanced stage that was too late for effective treatment. This is due to the early symptoms of this type of cancer is almost similar to other gastrointestinal symptoms such as abdominal pain, nausea or heartburn.

The researchers hope the breath test will offer an easier screening tool than endoscopy, where a specially trained medical professional looks at the inside of the stomach via a tube inserted down the patient's gullet, and sometimes also retrieves a biopsy sample of the stomach lining. *** [EKA | FROM VARIOUS SOURCES | SCIENCEDAILY | BBC | SRI | PIKIRAN RAKYAT 14032013]
