New small cell lung cancer research from Gunma University, Medical Department discussed.

According to a study from Maebashi, Japan, "Non-small cell lung carcinomas (NSCLC) overexpress the Her2/neu gene in approximately 59% of cases. Trastuzumab, a humanized monoclonal antibody, interferes with Her2 signaling and is approved for the treatment of Her2/neu overexpressing breast cancer."

"However, its therapeutic use in Her2/neu overexpressing NSCLC remains obscure. The present study aimed to determine the role of 64 Cu-labeled trastuzumab positron emission tomography (PET) for non-invasive imaging of Her2/neu expression in NSCLC. Trastuzumab was conjugated with the bifunctional chelator 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA) and …
