Dr. West moderates a question & answer session with Drs. Leora Horn and Greg Riely on issues of acquired resistance to targeted therapies for patients with advanced NSCLC that harbors a driver mutation.

Dr. Greg Riely from Memorial Sloan-Kettering Cancer Center reviews the limited data that help clarify the probability of benefit from new immunotherapy agents among patients with advanced NSCLC and an identified driver mutation.

Dr. Leora Horn of Vanderbilt University reviews the rapidly evolving issue and growing value of repeat biopsies, including plasma sampling as a "liquid biopsy" option, in the setting of acquired resistance to a driver mutation in advanced NSCLC.

Dr. West moderates a question & answer session with Drs. Karen Reckamp and Taofeek Owonikoko on issues of acquired resistance to targeted therapies for patients with advanced NSCLC that harbors a driver mutation.

Drs. Ben Solomon, Leora Horn, & Jack West compare the clinical data with the third generation EGFR TKIs so active in acquired resistance and consider whether there are significant differences between them.

Dr. Karen Reckamp of City of Hope Cancer Center reviews the concept of acquired resistance to targeted therapies in patients with a driver mutation and why it occurs.

Dr. Taofeek Owonikoko reviews why we often see brain metastases develop as a first or only site of progression in patients with NSCLC and a driver mutation.

Drs. Leora Horn, Ben Solomon, & Jack West discuss the open question of whether there are clinically significant differences among leading EGFR tyrosine kinases based on the specific EGFR mutation to be treated.

Drs. Ben Solomon, Leora Horn, & Jack West review whether the data and clinical experience suggest any clinically significant differences among the first and second generation EGFR TKIs (Iressa, Tarceva, Gilotrif/Giotrif).

Drs. Ben Solomon, Leora Horn, & Jack West consider the range of treatment options for patients with an EGFR mutation and acquired resistance that does not harbor a T790M mutation.
