Ari Melnick, MD, a professor of medicine at the Weill Cornell Medical College, discusses the challenges associated with measuring tumor heterogeneity.
- Measuring variability requires looking at many methylated sites in the genome, which is unlikely to become a routine test
- There remains a need for a way to measure tumor heterogeneity in a reliable and meaningful way
- Researchers are currently looking for siâ€‹tes in the genome that may be a surrogate marker for genome-wide profiling
- It is impossible to target diversity from the genetic standpoint, though epigenetic diversity could be targeted
- Hypothetically, drugs could demethylate the genome to make it more uniform
