Number of Regional Lymph Nodes Examined at This Facility (CoC) RX Hosp--Reg LN Examined	676	2	CoC	786-787

Description
Describes number of regional lymph nodes removed at the reporting facility as part of the first course of treatment.

Rationale
If central registries wish to study the treatment given at particular facilities, the facility-level treatment fields must be used. The summary treatment fields, conversely, combine information for all hospitals that provide first course of treatment for the tumor. Facility-specific fields allow studies of detailed referral patterns and treatment by type of healthcare setting. Knowing the extent of treatment given at a particular facility also helps resolve consolidation issues.
