Rinse the mouth to detect cancers of the head and neck




Able to researchers from the Comprehensive Cancer Center of the University of Miami in the United States to reach a mouthwash that can detect early the presence of cancer Aharhvi cells in the head and neck.
They adopted the scientists to investigate the function of a protein and a cancer CD44, in addition to changing the DNA due to the presence of cancer, which can strongly differentiate between cancer and other offices.
At the present time, recover only 50% of patients with head and neck cancer be cured, because there is often only discovered late, especially for poor patients, as they do not receive adequate health care that might help them in finding the disease only too late.
However, the new lift lye cure rate to 80% among cancer patients, and any health center in any country get it easily, as it reveals the existence of head and neck cancer in 90% of cases, according to the professor to assist in Otolaryngology at the University of Dr. Elizabeth Franzman, which published the study on the launches in the Bulletin of the American Society for Cancer Research American Association for Cancer Risrc.
The way of the work of lye to the fact that the protein CD44 on the surface of cells in healthy tissue, while it brings about at least 7 times in the infected tissues, which can be removed when the lye touching of cell membranes and, therefore, appear in the rinse samples reveals the existence of cancer.
However, preliminary tests showed some errors in the readings, as Dr. Vrenzman and her team examined 102 people with cancer, and 69 individuals infected with benign tumors have a history of smoking or drinking alcohol, and turned out to be lye-based CD44 did not reveal the presence of cancer in only 62 cases only.
Therefore decided to adopt another pointer to indicate the cancer, which is to increase the methanol catalyst in the genes, since in many cancer cells are modified DNA is chemically unchanged the basic structure, and therefore increasing the methanol is a catalyst for the growth of cancer cells, because stop the work of the genes controlling cell growth.
According to Vrenzman, the oral rinse contains enough cells to investigate the DNA Almithani, where one study showed that the increase in methanol in the sample of lye was able to detect the presence of head and neck cancer in 9 patients out of 11 patients with the proportion of CD44 is not sufficient to have the first study
