The term “HER2-positive lung cancer” may actually refer to two distinct entities, according to a new study. HER2 mutations and HER2 amplifications were found in similar numbers of lung adenocarcinoma cases, but they did not occur in the same samples, suggesting HER2-targeted agents should differentiate between mutation and amplification.

Laboratory studies of mice and human cells found that a protein called Metastasis suppressor 1 (Mtss1) is downregulated in hematopoietic and progenitor cells when chronic myeloid leukemia is present. Mtss1 levels are restored when complete remission is achieved, suggesting the pathway might represent a new therapeutic target.
