Q&A on ALK Inhibitor Therapy, with Drs. Ben Solomon and Ross Camidge


Following the terrific presentations by Drs. Ben Solomon and Ross Camidge on the science and clinical experience with the novel ALK inhibitor XALKORI (crizotinib), we had a question and answer session, which is now available as a podcast. Here's the audio podcast and transcript for it (not really a video component for this one).



Who to Test for an EGFR Mutation or ALK Rearrangement: Filtering Based on TTF-1 Status


Thyroid transcription factor-1 (TTF-1) is a protein seen on the surface of thyroid cells, but also on about 70-75% lung adenocarcinomas and only a small minority (~10%) of squamous cell NSCLC tumors. In fact, the presence of TTF-1 on a NSCLC tumor provides a good hint for the pathologist that this is an adenocarcinoma. It's an immunohistochemical (IHC) test that is done on the vast majority of lung cancers, and there's some new information that suggests it may also be useful for predicting which patients are especially unlikely to have an EGFR mutation or ALK rearrangement.
