Maybe I'll go first.
The lung cancer risk predictor is to identify which of the current or former smokers would develop lung cancer or harbour an early lung cancer that could be detected by low-dose CT. It is based not only on smoking history, but on things like age, educational level, body mass index, family history of lung cancer, and a number of other barometers. It's something we can use on an iPad or an electronic medical record. The patient can answer a few questions within about 5 to 10 minutes and then we can determine the lung cancer risk.
This is just to see who would benefit from low-dose CT screening. The biomarker that Dr. Ionescu talked about is for people who already have lung cancer, in order to find out which of the targeted therapies they would benefit from.
