CS is a group of data items set up by a joint task force including representatives from SEER, ACOS, CDC, NAACCR, NCRA, and AJCC, designed to provide a single uniform set of codes and rules for coding EOD/ stage information to meet the needs of all of the participating standard setters. CS incorporates all of the fields from SEER 10-digit EOD, in a modified form, and adds several additional fields. When CS data items are coded, a computer algorithm allows generation of AJCC Sixth Edition TNM stage, SEER Summary Stage 1977, and SEER Summary Stage 2000. Separate CS fields are provided in the NAACCR record for these outputs. This derived output records a "c," "p," "a," "y," or "N" for "clinical," "pathological," "autopsy only," or "y prefix", respectively. For those tumors in which AJCC TNM staging classification is performed during or following initial multimodality therapy, the category is identified by a "y prefix" to be derived from the computerized algorithm. ..
