Genetics

Genetic testing is more important now than ever before, as biomarker-driven cancer treatments continue to receive approval across many tumor types. While these personalized treatments are improving outcomes, navigating the landscape of genetic testing can leave patients with questions for their providers.

Getting an accurate family history can be one of the most challenging things that nurses face, according to Suzanne Mahon, DNSc, a clinical nurse specialist at SLUCare physician group, St Louis, Missouri.

Some patients with breast cancer might be apprehensive to undergo genetic testing, but it is crucial both for them and their family members. Lauren Carcas, MD, medical oncologist at the Miami Cancer Institute, discusses some main points nurses can make to these patients to encourage them to get tested.

The presence of the proteins p16 and p21 has shown to be predictive of treatment response in patients with osteosarcoma, a disease that previously had no identified biomarkers to indicate whether or not patients would benefit from therapy, explained C. Parker Gibbs, MD.

Not all patients with advanced non–small cell lung cancer (NSCLC) are recommended for genomic testing when treated in a community setting, and are therefore not being appropriately tested for potential molecular drivers of their disease, explained Nathan Pennell, MD, PhD.
