Guide for use: | Record the presence of extraprostatic extension (EPE) in a person with prostate cancer. This item should be completed both after diagnostic testing/imaging is completed and after surgery. Record "present" where EPE is clearly present, record "indeterminate" where it is unclear if EPE is present, and record "not identified" when there is no indication of EPE. Further details regarding this can be found in the RCPA Prostate cancer (radical prostatectomy) structured reporting protocol. The assessment of EPE can be difficult, as the prostate is not surrounded by a discrete, well defined fibrous capsule. Adding to the difficulty, there is often a fibrotic reaction in the vicinity of EPE, and the neoplastic extraprostatic glands are often seen in fibrous tissue, not fat. Therefore, EPE can be identified in several different situations and can be diagnosed by one of the following:
Tracking along the edge of the prostate at low power, EPE is present when there is bulging of the tumour beyond the normal rounded contour of the prostate gland. |
