Collaborative Stage

Note 1: Code the Gleason's primary and secondary pattern from prostatectomy or autopsy ONLY in this field.
Note 2: Usually prostate cancers are graded using Gleason's score or pattern. Gleason's grading for prostate primaries is based on a 5-component system (5 histologic patterns). Prostatic cancer generally shows two main histologic patterns. The primary pattern, that is, the pattern occupying greater than 50% of the cancer, is usually indicated by the first number of the Gleason's grade and the secondary pattern is usually indicted by the second number. These two numbers are added together to create a pattern score, ranging from 2 to 10.
    o    If only one number is given and it is less than or equal to 5, code the total score to 999, unknown or no information.
    o    If only one number is given and it is greater than 5, assume that it is a score.
    o    If there are two numbers, assume that they refer to two patterns (the first number being the primary and the second number being the secondary) and sum them to obtain the score.
    o    If the pathology report specifies a specific number out of a total of 10, the first number given is the score. Example: The pathology report says "Gleason's 3/10". The Gleason's score would be 3.
Note 3: If prostatectomy/autopsy is not performed, assign code 998. If the Gleason's pattern is not documented on prostatectomy/autopsy, assign code 999.
Note 4: If a tertiary pattern is documented on prostatectomy/autopsy, do not include in either Site-Specific Factor 9 or Site-Specific Factor 10. Record the tertiary pattern in Site-Specific Factor 11.
