The HER2 gene which is found in women with breast cancer, has been linked with canine pulmonary adenocarcinoma (CPAC) in dogs. Researchers at the Translational Genomics Research Institute (TGen) which is an affiliate of the City of Hope and Ohio State University found that a drug, neratinib, can help the over 40,000 dogs who develop CPAC each year.

CPAC is an aggressive cancer that is similar to the type of human lung cancer that non-smokers develop. This study has given researchers more information about the genetics of this disease and treatment options that can help both dogs and humans.
