42086-9

LOINC code 42086-9 identifies "Collaborative staging site-Specific factor 1 Cancer". This belongs to the set of Collaborative Staging (CS) data items effective with 2004 diagnosis. The "CS Site-Specific Factor" items (1-6) are used to code additional site-specific information needed to derive TNM or AJCC stage, or to code prognostic factors that have an effect on stage or survival. Some site-specific information that was formerly recorded in "EOD-- Tumor Size" [780] (Breslow's Thickness for melanoma; HIV/AIDS status for lymphoma) is now also in "CS Site-Specific Factor" items. Many site-specific schemas do not use any of the Site-Specific Factors; other schemas use from 1 to all 6 of the factors. CS Site Specific Factors provide an optional area for coding information needed for stage. 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 .. NAACCR Data Standards and Data Dictionary Version 11

This code measures Collaborative staging site-specific factor 1 in Cancer.XXX. It belongs to the TUMRRGT class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
