Peer-to-peer prep
- Have the NCCN page reference open on screen (version + page #)
- Open the patient's biomarker report alongside the chart
- Lead with the FDA-approved indication; pivot to NCCN if at the edge of the label
- State the line of therapy explicitly (1L, 2L, 3L) — common point of P2P misunderstanding
