Genetic profile of treatment-resistant lung cancer more variable than previously understood
Study finds that acquired resistance mechanisms to targeted therapies often changed over time and that some patients demonstrated simultaneous genetic mutationsThe genetic mutations underlying treatment resistance in non-small cell lung cancer (NSCLC) are more complex and dynamic than previously thought. Analysis of 355 biopsied tumors from patients who acquired resistance to EGFR inhibitors, the most common form of targeted therapy for NSCLC, found that mutations frequently varied between biopsies and that nearly one in five patients harbored more than one type of genetic resistance to
