Collaborative Stage for TNM 7 - Revised 11/12/2010 [ Schema ]
CS Site-Specific Factor 13
Number of Cores Examined
- Note 1: Record the number of prostate core biopsies examined for cancer documented in the pathology report. Do not make assumptions on the number of cores examined based on the number of anatomic locations biopsied because often several cores are submitted per site. Fragments are not synonymous with cores and are not counted as cores unless the pathologist has included the fragments in the core count. If the number of cores examined is not specifically documented, code 991.
- Note 2: If multiple needle core biopsy procedures are performed during the initial diagnostic workup, do not add together the cores examined from the separate procedures. Record the number of cores examined from the procedure with the highest number of cores positive, the same procedure used to record CS Site-Specific Factor 12.
