Collaborative Stage for TNM 7 - Revised 12/07/2009 [ Schema ]
Prostate
CS Site-Specific Factor 8
Gleason's Score on Needle Core Biopsy/TURP
- Note 1: Code the Gleason's score from needle core biopsy or TURP 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: Record the Gleason's score based on the addition of the primary and secondary pattern coded in Site-Specific Factor 7.
- Note 4: If multiple needle core biopsies performed or needle core biopsy and TURP both performed, code the highest or most aggressive score.
- Note 5: If needle core biopsy/TURP is not performed, assign code 998. If the Gleason's score is not documented on needle core biopsy/TURP, assign code 999.
