We are in the midst of a remarkable transitional time in cancer care that is exciting but challenging, since we now have patients divided into smaller and smaller groups based on molecular markers.  Along with that, more and more patients and caregivers are participating in social media and online discussion groups.  What are the implications for these changes, and how can we use them to accelerate the pace of clinical research?  I'd like to focus on a couple of key questions for our next lung cancer tweetchat on September 26, at 8 PM Eastern, 5 PM Pacific.
