Question:

Grade, Differentiation--Prostate: Has SEER officially changed the conversion code for Gleason score 7 to poorly differentiated [grade 3]?

Discussion:

Answer:

For cases diagnosed prior to 2003, there has been no change in SEER standards for converting a Gleason score to a grade. As described in the SEER Program Code Manual, Gleason score 7 is converted to moderately differentiated [grade 2]. ONLY if the pathology report lists moderately poorly differentiated IN ADDITION to the Gleason's score 7, would you code the case as 3.

For cases diagnosed in 2003 and later, please see question number 20031123.
