Precision Medicine For Your Practice is a series of short (20-30 min), online modules covering specific topics in genomics and precision medicine. In this module, Exploring Somatic Cancer Panel Testing, participants will learn about large somatic cancer panels, which test for dozens or hundreds of variants that may be driving cancer growth and suggest therapeutics targeted to the variants that are identified. When should these panels be used? And which patients are good candidates? Learn about benefits, limitations, and challenges of using large somatic cancer panels using the five parts of this module: overview information via an animated video; practice cases to facilitate learning-by-doing; "dig deeper" for more in-depth topics; and logistics and additional resources for more detail.
