Can a Breathalyzer Sample Detect Lung Cancer?

Wednesday, June 25th, 2014


A new study presented recently at the American Society of Clinical Oncology conference in Chicago concluded that anew brethalyzer using a NaNose nanotech chip  may accurately detect lung cancer and identify the stage of progression. .The breathanalyzer is based upon the knowledge that lung cancer tumors produce chemicals called volatile organic compounds (VOC) that easily evapotate into air and produce a discernible scent.  The study included 358 patients who were either diagnosed with or at risk for lung cancer. The device accurately distinguished healthy people from  those with early stage lung cancer 85 percent of the time, and healthy people from those with advanced stage lung cancer 82 percent of the time. The test also accurately distinguished those with early from late stage lung cancer 79 percent of the time. The researchers hope the test will allow lung cancer patients to be diagnosed with a non-invasive procedure and a Boston Based company , Alpha Szenszor, has liscenbced the technology and plans to introduce it to the market within the next few years.

Is there a Non-Invasive Procedure to Diagnose Pancreatic Cancer?

Wednesday, May 28th, 2014

logo1267406_mdNew research presented recently at the American Society for Microbiology”s  annual meeting concluded that patients with pancreatic cancer have a different and distinct profile of specific bacteria int their saliva compared to healthy controls and  patients with other cancers or pancreatic disease. The researchers believe that the ratio of particular types of bacteria in the saliva may indicate pancreatic cancer. In their study, the researchers compared the diversity of saliva bacteria of 131 patients (63 females, 68 males) being treated in California. Of those, 14 had been diagnosed with pancreatic cancer, 13 with pancreatic disease, 22 with other forms of cancer, and 10 who were disease free. Results showed that those with pancreatic cancer had higher levels of two oral bacteria-Leptotrichia and Campylobacter when compared to the healthy or those with diseases including pancreatic disease. Those with pancreatic cancer also had lower levels of Streptococcus. Treponema, and Veillonelia. Researchers concluded “Our results suggest the presence of a consistently distinct microbial profile for pancreatic cancer.”
