Gleason Tertiary Pattern
**Note 1:** Physician statement of Gleason tertiary pattern can be used to code this data item when there is no other information available.
**Note 2:** If present, a high Gleason Tertiary Pattern appears to be an indication for a worse outcome.
**Note 3:** Record the tertiary pattern documented on prostatectomy or autopsy only. Record the tertiary pattern prior to neoadjuvant treatment.
* If a tertiary pattern is documented on needle core biopsy or transurethral resection of prostate (TURP), it should be disregarded.
* Do not code the tertiary pattern on prostatectomy or autopsy in Gleason Patterns Pathological.
**Note 4:** The CAP Prostate Protocol does not include Patterns 1 and 2 for Tertiary Pattern.
**Note 5:** If neoadjuvant therapy was given, code Gleason patterns as X9.
