Description
Flag to indicate whether the derived SEER Summary Stage 2000 was derived from CS or EOD codes.
Rationale
The Collaborative Stage Data Collection System was designed by a joint task force including representatives from SEER, ACoS, CDC, NAACCR, NCRA, CCCR, CPAC, and AJCC, to provide a single uniform set of codes and rules for coding extent of disease (EOD) and stage information to meet the needs of all of the participating standard setters. When CS data items are coded, a computer algorithm provides the derivation of T, N, M, and stage-based on AJCC Cancer Staging Manual 6th & 7th Editions, SEER Summary Stage 1977, and SEER Summary Stage 2000. There are separate derived CS fields in the NAACCR record based on AJCC 6th Edition for 2004+ cases and AJCC 7th Edition for 2010+ cases.
Codes (See the most current version of the
    Collaborative Stage Data Collection System (http://cancerstaging.org/cstage/manuals.html),13 for rules and site-specific codes and coding structures.)
