      1. -Stage at diagnosis is calculated using the Combined Summary Stage (2004+) recode, created from SEER Combined Summary Stage 2000 (2004-2017) & Derived Summary Stage 2018 (2018+). For more information, see the SEER documentation[https://seer.cancer.gov/seerstat/variables/seer/lrd-stage].
    stage period caveat
    Combined Summary Stage (2004+) uses coding starting in 2004; the 2000-2021 label must not be read as full stage-specific coverage from 2000.
