Collaborative Stage

Note 1: Include information from prostatectomy and autopsy in this field and not in CS Extension - Clinical Extension. ONLY use histologic information from prostatectomy and autopsy in this field. Information from needle core biopsy is coded in Site-Specific Factor 14.
Note 2: Code 970 if there was no prostatectomy performed within the first course of treatment.
Note 3: Limit information in this field to first course of treatment in the absence of disease progression.
Note 4: Involvement of the prostatic urethra does not alter the extension code.
Note 5: When the apical margin, distal urethral margin, bladder base margin, or bladder neck margin is involved and there is no extracapsular extension, use code 400.
Note 6: CODES 020 - 099 have been made OBSOLETE, CODES NO LONGER USED. Codes 020-030, 032 and 040-099 have been converted to codes 200-999 in CS Version 2. Codes 031, 033 and 034 in this range have been made obsolete in CS Version 1 as information about prostate apex involvement has been moved to Site-Specific Factor 4, Prostate Apex Involvement. AJCC does not use prostate apex involvement in the "T" classification.
Note 7: When prostate cancer is an incidental finding during a prostatectomy for other reasons (for example, a cystoprostatectomy for bladder cancer), use the appropriate code for the extent of disease found (for example, one lobe, or both lobes, or more).
Note 8: "Frozen pelvis" is a clinical term which means tumor extends to pelvic sidewall(s). In the absence of a more detailed statement of involvement, assign this to code 600.
Note 9: AUA stage. Some of the American Urological Association (AUA) stages A-D are provided as guidelines for coding in the absence of more specific information in the medical record. If physician-assigned AUA stage D1-D2 is based on involvement of lymph nodes only, code under CS Lymph Nodes or CS Mets at DX, not CS Extension - Pathologic Extension.
Note 10: For information regarding stage calculations, refer to CS Extension - Clinical Extension Note 7 and the special calculation extra tables.
