limitations

Published aggregate registry statistics; no individual-level records.
Five-year relative survival is not overall survival, a treatment effect, or an individual prognosis.
Year-of-diagnosis trends are not survival curves across follow-up time.
Null age_range means no explicit age subgroup in the source; it does not mean age zero.
No survival age adjustment is asserted unless explicitly documented.
Do not join pooled current estimates onto annual historical trends: registry coverage and cohorts differ.
