NAACCR XML: Tumor.csSiteSpecificFactor25

Description
Identifies additional information needed to generate stage, or prognostic factors that have an effect on stage or survival.
Rationale
CS Site-Specific Factor25 is used to discriminate between CS staging schema or between AJCC chapters where site and histology alone are insufficient to identify the tumor type or location to identify the applicable staging method.
Codes (The information recorded in CS Site-Specific Factor25 differs for each anatomic site. See the most current version of the Collaborative Stage Data Collection System (http://cancerstaging.org),13 for rules and site-specific codes and coding structures.)
