How has cancer care changed with advances in genomic medicine? For example, for patients diagnosed with melanoma today, will their treatment options be different than those that were available 10 or 15 years ago?
These are some of the questions we posed to Aleksandar Sekulic, M.D., Ph.D., associate director, Mayo Clinic Center for Individualized Medicine, who now has a new role as deputy director, Mayo Clinic Cancer Center, in Arizona. Dr. Sekulic explains how genomics has already advanced cancer care, and how it will continue to impact cancer screening and treatment in the future.
Question: What did the Human Genome Project, which mapped the first human genome, tell us about how our genes impact our health and diseases like cancer?
Dr. Sekulic: The Human Genome Project revealed important insights into how our genetic code controls mechanisms that affect health and disease. We now know that cancers are caused by abnormalities occurring in our genes and this changed the way we approach cancer. For example, fifteen years ago, we largely viewed melanoma as a single disease. Now we know melanoma is a group of diseases, each with a different set of genes driving the cancer. Today, we’re using this knowledge to develop individualized diagnostic tests and targeted treatments for patients.
Q: How has cancer care improved with use of genetic and genomic testing?
Dr. Sekulic: There are many current and emerging advances in cancer care, including:
Q: Why is pharmacogenomics testing important in choosing the right cancer treatment?
Broadly, pharmacogenomics assesses the way a person’s genes affect how they process medications, and as such it can play a critical role in selecting the right treatment and dose for patients, including cancer patients. At Mayo, we can currently test for sensitivity to more than 400 medications with a blood-based pharmacogenomics test. This is important because many cancer patients are placed on more than one medication at a time. These test results can be helpful in selecting the right drugs and dosages, maximizing the benefit of the therapy and reducing the chance for any harmful side effects.
Q: What’s on the horizon for new developments in cancer care?
Dr. Sekulic: There are many opportunities to improve care as our knowledge grows. Some of these areas include:
