Blood Test May Point Out Lung Cancer Symptoms
Lung cancer remains the deadliest cancer, with 26,624 deaths in 2005, and affects mainly men (78% of 31 000 cases in 2005). However, mortality from lung cancer in humans decreases while increasing in women (+ 4.2% per year) at an alarming rate. The progression of lung cancer in women is in line with increase of smoking between 2000 and 2005.
The diagnosis of lung cancer is often long. The first symptoms of lung cancer that are shown by a scanner or a bronchial fibroscopy already give the disease the time it needs to develop. The average five-year survival is only around 15%.
The question of early detection of lung cancer may still be a subject to a surgical treatment. However, this may change. A company called BioSystems, which specializes in finding innovative cancer diagnostics, has worked on a blood test for detecting a tumor.
BioSystems identified thirteen specific antibodies in lung cancer, which "revealed a very good sensitivity, greater than 80%," says its CEO, Jean-Pierre Tirouflet, in Le Parisien on Monday. He recalled that "the PSA, which is only tested for prostate cancer, shows a sensitivity of 35%."
Tested in September at the hôpitel Avicennes Bobigny (Seine-Seint-Denis), this blood test for lung cancer diagnosis may be prescribed by doctors to smoking patients every six months. The blood test may not only serve as a means testing to find the early symptoms of lung cancer, but also as a means for prevention of the disease.
