Question: Is it precision medicine or personalized medicine?
Answer: Both
“Precisionalized Medicine”

Precision MedicineLessons Learned
Use combinations of matched drugs for metastatic or complex tumors
Treat newly-diagnosed patients
Omics is a disruptive technology; retrofitting the reality unveiled into traditional paradigms is suboptimal
Harness the immune system
Transformative changes will require new models for clinical research and practice

Master ProtocolProfile-Related Evidence Determining
Individualized Cancer Therapy
PREDICT• Histology-Independent targeted approach
• Multiple molecular aberrations assessed
• Patients matched with targeted agents

The Reclassification of Cancer
PIK3CA mutations were found in 10% of 1,000 patients with advanced cancers
• Endometrial cancers (29%)• Breast cancers (24%)• Colon cancers (17%)• Ovarian cancers (14%)• Lung cancer (13%)• Head and neck squamous cell cancers (13%)• Pancreatic cancers (13%)
Molecular aberrations do not segregate well by organ of origin
