Researchers reveal genomic diversity of individual lung tumors

Known cancer-driving genomic aberrations in localized lung cancer appear to be so consistently present across tumors that a single biopsy of one region of the tumor is likely to identify most of them, according to a recent paper. The study, led by scientists at The University of Texas MD Anderson Cancer Center, addresses the challenge of what scientists call genomic heterogeneity, the presence of many different variations that drive tumor formation, growth and progression, and likely complicate the choice and potential efficacy of therapy.
