Dr. Jack West, Swedish Cancer Institute, reviews trial evidence for the efficacy of rociletinib and osimertinib for EGFR acquired resistance not driven by a T790M mutation.

Drs. Jack West and Greg Riely field questions about which treatments should EGFR lung cancer patients consider when their cancers progress.

Dr. Jack West suggests that progression in T790M-negative EGFR lung cancer patients may not require a change in therapy. In this video he details what should go into the decision to modify treatment for those patients.

Acquired resistance in EGFR patients is often driven by the T790M mutation. T790M-positive tumors respond differently to treatments than T790M-negative tumors. Dr. Greg Riely details how each status can predict patients' responses to current treatments.

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.

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. Leora Horn, Ben Solomon, & Jack West consider whether third generation EGFR TKIs, so active in patients with acquired resistance, might be best used prior to development of acquired resistance.

Dr. Greg Riely, medical oncologist from MSKCC, discusses the controversial question of whether patients should continue on an oral EGFR tyrosine kinase inhibitor after progression.

MSKCC medical oncologist Dr. Greg Riely explains the growing value of a repeat biopsy after the development of acquired resistance in patients with an EGFR mutation.
