Field Length: 1
Identifies the AJCC clinical stage (prefix/suffix) descriptor of the tumor prior to the start of any therapy. Stage descriptors identify special cases that need separate analysis. The descriptors are adjuncts to and do not change the stage group. This field may not be left blank for cases diagnosed 1/1/2010 forward.
Instructions for Coding
• Record the clinical stage (prefix/suffix) descriptor as documented by the first treating physician or the managing physician in the medical record.
• If the managing physician has not recorded the descriptor, registrars will code this item based on the best available information, without necessarily requiring additional contact with the physician.
• If the tumor is not staged according to the AJCC manual, leave this data item blank.
• Refer to the current AJCC Cancer Staging Manual for staging rules.
• Previous editions of FORDS included a code 4 for y-classification, and a note that it was not applicable for clinical stage. Code 4 has been removed from the list of valid codes.
