Note 1: Include information from prostatectomy in this field and not in CS Extension - Clinical Extension.Use all histologic information including the prostatectomy if it was done within the first course of treatment.Code 097 if there was no prostatectomy performed within the first course of treatment.
Note 2: Limit information in this field to first course of treatment in the absence of disease progression.
Note 3: Involvement of the prostatic urethra does not alter the extension code.
Note 4: When the apical margin, distal urethral margin, bladder base, or bladder neck margin is involved and there is no extracapsular extension, use code 040.
Note 5: CODES 031, 033 and 034 have been made OBSOLETE, CODES NO LONGER USED.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 6: 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 7: "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 060.
Note 8: 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 9: For the extension fields for this site, the mapping values for TNM, SS77, and SS2000 and the associated c, p, y, or a indicator are assigned based on the values in CS Extension, CS TS/Eval, and Site-Specific Factor 3.If the value of Site-Specific Factor 3: Pathologic Extension is greater than 000 and less than 095 (i.e., prostatectomy was done, extension information is available for staging, and invasive tumor was present in the prostatectomy specimen), the mapping values are taken from the Site-Specific Factor 3 mapping, and the T category is identified as a pT.If Site-Specific Factor 3: Pathologic Extension code is 095 or greater (meaning that prostatectomy was not performed, or it was performed but the information is not usable for staging), the mapping values are taken from the CS Extension (Clinical Extension) mapping, and the c, p, y, or a indicator is taken from the TS/Ext Eval mapping.If Site-Specific Factor 3: Pathologic Extension code is 000 (in situ), and if CS Extension code (Clincal Extension) is greater than 00 and less than 95 (not in situ) , the mapping values are taken from the CS Extension (Clinical Extension) mapping, and the c, p, y, or a indicator is taken from the TS/Ext Eval mapping.If Site-Specific Factor 3 code is 000 (in situ) and CS Extension code is 00 (in situ) or greater than 95, the mapping values are taken from the Site-Specific Factor 3 mapping, and the T category is identified as a pT.
