Innovative gastric cancer-detection technology<\/figcaption><\/figure>\n

Innovative gastric cancer-detection technology developed by the Technion can be used for the early detection of stomach cancer and for identifying persons at risk for developing the disease. The new detection method, based on breath analysis, has significant advantages over the existing detection technology: Gut<\/i> reports that the new method is quick, simple, inexpensive and non-invasive.<\/p>\n

Gastric cancer is one of the most lethal forms of cancer and in most cases, its diagnosis involves an endoscopy (the insertion of a tube into the esophagus, requiring that the patient fast and receive an intravenous sedative). Treatment is aggressive chemotherapy, radiation and the full or partial removal of the stomach. The disease develops in a series of well-defined steps, but there\u2019s currently no effective, reliable, and non-invasive screening test for picking up these changes early on. Thus, many people succumb to stomach cancer only because it was not diagnosed in time.<\/p>\n

The new technology, developed by Prof. Hossam Haick\u00a0of the Wolfson\u00a0Faculty of Chemical Engineering, can be used to detect premalignant lesions at the earliest stage, when healthy cells start becoming cancerous.<\/p>\n

The research, published in Gut<\/i> as part of the doctoral thesis of Mr. Haitham Amal, was conducted in conjunction with a Latvian research group headed by Prof. Marcis Leja, based on the largest population sample ever in a trial of this type. 484 people participated in the trial, 99 of whom had already been diagnosed with stomach cancer. All the participants were tested for Helicobacter pylori<\/i>, a bacterium known to increase the risk for stomach cancer, and two breath samples were taken from each person.<\/p>\n

The first sample from each participant was analyzed using the GCMS technique, which measures volatile organic substances in exhaled breath. The researchers noted that GCMS technology cannot be used to detect stomach cancer because the testing is very expensive and requires lengthy processing times and considerable expertise to operate the equipment.<\/p>\n

The second breath sample was tested using nanoarray analysis, the unique technology developed by Prof. Haick, combined with a pattern recognition algorithm.<\/p>\n

The findings:<\/strong><\/p>\n

    \n
  1. Based on the concentrations of 8 specific substances (out of 130) in the oral cavity, the new technology can distinguish between three groups: gastric cancer patients, persons who have precancerous stomach lesions, and healthy individuals.<\/li>\n
  2. The new technology accurately distinguishes between the various pre-malignant stages.<\/li>\n
  3. The new technology can be used to identify persons at risk for developing gastric cancer.<\/li>\n
  4. The diagnosis is accurate, regardless of other factors such as age, sex, smoking habits, alcohol consumption and the use of anti-oxidant drugs.<\/li>\n<\/ol>\n

    In short, the nano-array analysis method developed by Prof. Haick is accurate, sensitive technology that provides a simple and inexpensive alternative to existing tests (such as GCMS). This new technology offers early, effective detection of persons at risk for developing stomach cancer, without unnecessary invasive tests (endoscopy). In order to assess the accuracy and effectiveness of the new, a wide-scale clinical trial is currently under way in Europe, with thousands of participants who have cancerous or pre-cancerous tumors.<\/p>\n

    About Prof. Hossam Haick<\/b><\/p>\n

    Prof. Hossam Haick, who joined the senior staff at the Technion Wolfson Faculty of Chemical Engineering in 2006, has been working since that year on the development of innovative, non-invasive technology for detecting cancer and other diseases. This technology is based on an \u201celectronic nose\u201d \u2013 an apparatus capable of detecting illnesses by analyzing a patient\u2019s exhaled breath.<\/p>\n

    Prof. Haick, a native of Nazareth, completed his Ph.D. studies at the Technion by the time he was 27 and went to the Weizmann Institute of Science in Rehovot and Caltech Institute of Technology in California. He returned to the Technion in 2006 and his research group was awarded one million euros in grants by the European Union, which was very impressed by his research into artificial olfactory systems. Today he heads a consortium that includes Siemens and several universities, research institutes and companies in Germany, Austria, Finland, Ireland, Latvia and Israel. Since joining the senior faculty in the Chemical Engineering Department in 2006, Prof. Haick has won dozens of awards, grants and international honors. These include the Marie Curie Excellence Grant, European Research Council (ERC) grant and the Bill & Melinda Gates Award. Prof. Haick was nominated to MIT\u2019s list of the 35 leading young scientists worldwide, received the Knight of the Order of Academic Palms, from the French Government and won the Hershel Rich Technion Innovation Award (twice), as well as the Tenne Prize for Excellence in the Science of Nanotechnology. He has also been recognized for his outstanding teaching skills and is the recipient of the Yanai Prize for Academic Excellence. In 2014, at the initiative of the president of the Technion, Prof. Haick headed an MOOC (Massive Open Online Course) in nanotechnology and nano-sensors that had an enrollment of 42,000.<\/p>\n

    Prof Haick is a faculty member at the Russell Berrie Nanotechnology Institute<\/a>.<\/strong><\/span><\/p>\n
