What we are striving for in cancer care today is personalized medicine. So, if a patient with newly diagnosed NSCLC has an activating epidermal growth factor receptor (EGFR) mutation, we give that patient Tarceva (erlotinib), a tyrosine kinase inhibitor (TKI). Right? Well, yes -- but it doesn’t always work (the response rate is in the 70-75% range). Why not? We’re not sure, but it would be nice to learn why we don't see near a 100% response rate among patients with EGFR mutations, so that we can know to recommend other alternatives.
Brain metastases from NSCLC is almost a field of its own. This is because of the relatively high frequency with which metastases appear, the fact that they may return, even after treatment with whole brain radiation therapy (WBRT), and that our chemotherapy has long been considered to be ineffective against them. In fact, the extent of them as a problem is reflected in the number of thread questions on this subject in the GRACE forum.
As more and more oncologists become aware of the importance of testing for at least the EGFR mutation in tumor, and soon, perhaps, in blood, it seems likely that more patients will have their first systemic treatment for advanced non-small cell lung cancer (NSCLC) be an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), usually Tarceva (erlotinib), until Iressa (gefitinib) is re-approved (perhaps).
When oncologists and surgeons talk about staging, we often distinguish between clinical and pathologic staging. Many in the health care field don’t understand or know the difference. Even more, why do we “stage” a cancer (NOT the patient!) at all? These are important questions, because they tell those of us involved in the treatment and care of such patients what is the extent of the disease, what the prognosis might be, and what the treatment plan should entail. That way, the caregivers are all “on the same page".
