LOINC long common name : Lymph node involvement Cancer;
LOINC short name : LN involved Cancer;
LOINC description : Part of the 10-digit EOD [779]. Detailed site-specific codes for anatomic EOD used
by SEER for tumors diagnosed from 1988 forward. Codes were revised effective January
1, 1998, to reflect changes in the AJCC Cancer Staging Manual, Fifth Edition. Site-specific
EOD codes provide extensive detail describing disease extent. The EOD codes can be
grouped into different stage categories for analysis (e.g., historical summary stage
categories consistent with those used in published SEER data since 1973, or more recently,
AJCC stage groupings). The codes are updated as needed, but updates are usually backward
compatible with old categories. See Comparative Staging Guide for Cancer... NAACCR
