Subscribers Anyhow, we can use the single gene, but we know this is just a matter of time before more effective inhibitors will also show benefit for early-stage disease. Contact Us This book describes the molecular mechanisms of lung cancer development and progression that determine therapeutic interventions in the era of genomics, when the rapid evolution in lung cancer diagnosis and treatment necessitates critical SOCINSKI: Yes, I suspect the lung cancer population may be different from, say, the breast cancer population. The drug may still inhibit cancer growth, but is less likely to cause dramatic tumor shrinkage. Targeted drugs bring benefits for these NSCLC patients with driver gene variations. When were honest with that opinion when treating lymph nodepositive disease, or a 7- to 8-cm tumor with visceral invasion, thats a completely different scenario. Undoubtedly, EGFR-TKIs, with their . Molecular subtyping and MRD detection might be the potential ways to break through the current dilemma and maximize the survival benefits.

[However], in a setting where cure is the goal, we dont know that were going to cure more patients. gefitinib, erlotinib . Meaning chemotherapy may be offered first in stead. Treatment for EGFR-Mutant Lung Cancer After Progression on EGFR TKI Source: Taking Aim at HER3 in Lung Cancers Resistant to EGFR Inhibitors. PEREZ: Ordering has become a little easier in our practicewe order next-generation sequencing [NGS] for all patients. Because youre having these same conversations with patients with breast cancer and patients with colon cancer, I assume, but is it the same conversation youre having with patients with lung cancer? Do you have those conversations with your patients? The benefit comes in at a higher stage because the placebo arm didnt do better. This drug is given as an infusion into a vein (IV). SOCINSKI: The points being made are pertinent. 1,2 More than 70% of patients with lung cancer are diagnosed with advanced non-small-cell lung cancer (NSCLC), and prognosis remains poor. *S.-Y.L. This result is supported by the fact that 73.2% of EGFR positive patients received TKI treatment in our study.
