April 11, 2011 (BRONX, NY) Just as inhaling cigarette smoke can cause lung cancer, inhaling medication may treat it. Two researchers at Albert Einstein College of Medicine of Yeshiva University have received a five-year, $2.4 million grant from the National Institutes of Health to clinically develop an inhaled therapy for lung cancer to be used before the cancer becomes malignant and spreads.
The grant recipients are Roman Perez-Soler, M.D., professor of medicine and associate director of clinical research at Albert Einstein Cancer Center; and Yiyu Zou, Ph.D., associate professor of medicine. Dr. Perez-Soler is also chair of oncology at Montefiore Medical Center.
Lung cancer is the leading cause of cancer mortality among men and women in the U.S. Each year, more than 220,000 are diagnosed and about 150,000 people die from the disease. The average five-year survival rate is only 15 percent, largely because nearly 80 percent of cases are diagnosed after the cancer has spread from the lungs to other organs in the body. Drs. Perez-Soler and Zou will take advantage of the fact that, for many years, the disease is confined to the bronchial epithelium (surface cells of the airways), where it lingers and develops in a premalignant state.
The research project involves inhaling a drug called 5-azacytidine to target the bronchial epithelium. 5-azacytidine is a demethylating agent, meaning it strips off methyl groups that have bound to genes and rendered them inactive. Since removing methyl groups can reactivate genes that suppress tumors, drugs such as 5-azacytidine can potentially treat a number of different types of cancers.
The first two years of the federally-funded study will focus on a mouse model of premalignant lung cancer, to determine what dose is likely to be safe and effective
