ESMO 2017 MESSAGES 1. Perform the multigenetest during 0-1 lines (29,2% chance versus 17,2% in 2+ line (MSKCC) and 7% last line (Goustave- Roussy) to change therapy) Test early and plan ahead. 2. We should treat newly diagnosed cancer with targeted therapy (CML experience) 3. We should consider personalized combination therapy (San Diego experience). (Raselle Kurzrock CureMatch)
