Cancer research discussed in this podcast is ongoing, so the data described here may change as research progresses. In this podcast, experts will discuss targeted therapy for lung cancer, including 2 new treatments that target a specific type of mutation or change in the EGFR gene in some cancer cells, called an EGFR exon 20 insertion. They will explain how targeted therapy works to treat cancer, why this specific mutation is different from other, more common EGFR mutations, and what these 2 new treatments mean for people with this type of cancer. This podcast will be led by Dr. Charu Aggarwal, Dr. Xiuning Le, Dr. Vamsidhar Velcheti, and Marcia Horn. Dr. Charu Aggarwal is the Leslye Heisler Associate Professor of Medicine in the Hematology-Oncology Division at the University of Pennsylvania’s Perelman School of Medicine in Philadelphia, Pennsylvania. She is also the Cancer.Net Associate Editor for Lung Cancer.  Dr. Xiuning Le is an assistant professor in the Department of Thoracic/Head and Neck Medical Oncology in the Division of Internal Medicine at the University of Texas MD Anderson Cancer Center in Houston, Texas.  She is also a Cancer.Net advisory panelist for lung cancer.  Dr. Vamsidhar Velcheti is the director of thoracic medical oncology at NYU Langone’s Perlmutter Cancer Center in New York, New York, and is also a Cancer.Net advisory panelist for lung cancer. Marcia Horn is the President and CEO of the International Cancer Advocacy Network and the executive director of the Exon 20 Group in Phoenix, Arizona.  View full disclosures for Dr. Aggarwal, Dr. Le, Dr. Velcheti, and Ms. Horn at Cancer.Net. Dr. Charu Aggarwal: Hello and welcome to this Cancer.Net podcast on new research in lung cancer. I'm Dr. Charu Aggarwal from the University of Pennsylvania.

Our podcast today is going to be about targeted therapy for non-small cell lung cancer, and specifically, 2 new treatments that target a specific type of mutation or change in the EGFR gene in some cancer cells. This mutation is called an EGFR exon 20 insertion. Dr. Velcheti, I'll start off with you. What is targeted therapy, and how does it work? Dr. Velcheti: So thank you, Charu. Lung cancer is a very complex biological disease. There are a lot of genes in the tumor cells that could be mutated, and understanding the type of genetic changes or mutations in the DNA
