Good morning, GRACErs.

Plenary Session: Lung Cancer in Never Smokers

Continued from part 1 Dr. West: You have a huge portion of your patients who have an EGFR mutation and we know that over time patients develop acquired resistance. So how do you approach the patients who have a great response initially, have a known EGFR mutation, and then you see that slipping away at slow progression? Do you continue the EGFR inhibitor? Do you add something to it? Do you change the dose? How do you approach that?

A few weeks ago I had the chance to speak with Dr. Tony Mok, who is a professor in the Department of Clinical Oncology at the Prince of Wales Hospital in Hong Kong and the Chairman of the Hong Kong Cancer Therapy Society.

The third and last podcast from our discussions with Dr. Lecia Sequist, of Massachusetts General Hospital and Harvard Medical School, covers the question & answer session that followed her excellent

Over the past several years, probably the biggest development in the field of NSCLC has been the recognition of the importance of molecularly-defined subgroups that help define the clinical patterns of how patients are likely to do with various treatments. We've seen this clearly illustrated with EGFR mutations vs.

The IPASS trial that randomized never-smoking Asian patients with a previously untreated advanced lung adenocarcinoma to either standard chemo with carboplatin/Taxol (paclitaxel) or the oral EGFR inhibitor Iressa (gefitinib) was a pivotal study that changed how many of us thought about NSCLC.

The Importance of Identifying Molecular Markers in Non-Small Cell Lung Cancer To understand the importance of molecular markers in the current and future treatment of lung cancer, one should first understand how lung cancer was classified up until the beginning of this decade. Pathologists would look at a sample of a patient's lung tumor under a microscope, and then make a judgment of whether the cells represented small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC).

We've already discussed prior work on Met as a potentially valuable target in NSCLC, as illustrated by work with ARQ-197 combined with the EGFR inhibitor Tarceva (erlotinib) has demonstrated encouraging early results.
