EOD Prostate Pathologic Extension

This input is used for staging

Notes

**Note 1:** 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:** Code 900 if there is 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:** 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. **Note 5:** Involvement of the prostatic urethra does not alter the extension code. **Note 6:** "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 7:** Code 950 is used when first course of treatment is active surveillance, but a 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,
