The APPOS Seattle 2026 (Advanced Practice Providers Oncology Summit) is a two-day continuing education conference scheduled for May 15–16, 2026, at The Hilton Bellevue Hotel.

This summit is organized by Horizon CME and is specifically designed for advanced practice providers (APPs), including NPs, PAs, pharmacists, and nurses, to provide them with the latest evidence-based strategies to improve cancer patient care and outcomes.

The agenda covers diverse topics, including the rising incidence of early-onset colorectal cancer, new treatments for non-small cell lung cancer, managing nutritional impact symptoms, and an APP-led panel on surveillance and survivorship clinics.
