EOD Prostate Pathologic Extension
Notes
**Note 1:** **Radical prostatectomy or autopsy results only**
* Only use histologic information from a radical prostatectomy and/or autopsy in this field.
* Information from biopsy of extraprostatic sites is coded in EOD Primary Tumor.
* Code results from a transurethral resection of prostate (TURP) or simple prostatectomy in EOD Primary Tumor
**Note 2:** **No radical prostatectomy or autopsy**
* Code 900 if there is no radical prostatectomy or autopsy performed within first course of treatment. (See also Note 9)
* A radical prostatectomy is defined as Surgery of Primary Site codes 50-70 (A500-A700)
* If Surgery of primary site is 00-30, 90, 99 (A000-A300, A900, A999) then code 900
* *Note:* Surgery of primary site can be 00 if an autopsy is done
**Note 3:** **Criteria for data item**
* Limit information in this field to first course of treatment in the absence of disease progression.
**Note 4:** **Incidental finding**
* When prostate cancer is an incidental finding during a prostatectomy for other reasons (for example, a cystoprostatectomy for bladder cancer), or an autopsy, use the appropriate code for the extent of disease found.
**Note 5:** **Radical prostatectomy, no residual disease**
* Code 300 when there is a microscopically confirmed clinical diagnosis of prostate cancer and the radical prostatectomy shows no residual disease
**Note 6:** **Prostatic urethra**
* Involvement of the prostatic urethra does not alter the extension code.
**Note 7:** **Frozen pelvis**
* "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 700.
**Note 8:** **No evidence of primary tumor**
* Code 800 is only to be used when there is a clinical diagnosis of prostate cancer that has not been microscopically confirmed (i.e., diagnosed via imaging with bone mets) and a radical prostatectomy or autopsy is done and there is no evidence of primary tumor.
**Note 9:** **Active surveillance, then Radical Prostatectomy**
* Code 950 is used when first course of treatment is active surveillance, but a radical prostatectomy is done at a later date due to disease progression or the patient changed their mind.
* When code 950 is used, code the following SSDIs as X9: Gleason Patterns Pathological, Gleason Score Pathological, and Gleason Tertiary
**Note 10:** **Coding unknown**
* Code 999 when
* Radical prostatectomy is performed, but there is no information on the extension
* Surgery of Primary Site is Prostatectomy, NOS (Surgery of Primary Site is 80)
* Unknown if surgery is done (Surgery of Primary Site is 99)
