Note: Historically, apex involvement has affected the stage classification, although it does not affect the AJCC 6th edition.This item allows collection of information about the involvement of the prostate apex with cancer, both clinically and at prostatectomy.In codes 110-550, the first digit represents the clinical status of apex involvement, and the second digit represents apex involvement found at prostatectomy, following these definitions:
When abstracting and coding apex involvement, try to determine if the cancer has extended into the apex from another part of the prostate or has arisen in the apex.
