Scientists find 26 genes promoting lung cancer
Finding could lead to new treatments tailored to specific patients
New York - In the largest effort of its kind, scientists have identified 26 genes that, when damaged, appear to promote lung cancer.
It's a step toward developing new treatments that can be tailored to specific patients.
The federally-funded project was the largest ever to screen genes for mutations in the most common form of lung cancer, called adenocarcinoma. The results more than double the catalog of genes implicated in that condition.
The findings, from scientists at a dozen institutions in the United States and Germany, appear in Thursday's issue of the journal Nature.
Lung cancer is the leading cancer killer in the United States and worldwide.
The study focused on tumors that originated in the lung and were surgically removed. But researchers also hope to study whether the same mutations appear in lung tumors that spread elsewhere.
The scientists sampled 188 tumors. They examined the makeup of 623 genes to look for those that were the most often mutated. The idea is that if a gene is mutated in so many tumors, it probably plays a role in the disease. The mutations clearly arose in the cancers because they did not appear in healthy tissue from the cancer patients.
