- European experts developed consensus guidelines for population-based cancer registries (PBCRs) on collecting cancer recurrence and progression (RP) data.
- Recurrence is defined as cancer return after a disease-free period following tumor-reductive treatment with complete response; progression is increased disease load without verified complete response.
- A 2023 survey showed 31% of PBCRs collect RP data for all cancer sites, but many need more resources, training, and clinical data access.
- The guidelines use a tiered data collection approach and cover transformation from indolent to aggressive tumors; implementation began January 2025.
- Standardized RP data collection by well-resourced PBCRs is crucial for quantifying service needs and outcomes for the growing number of cancer patients.
