nameMargin involvement [Type] in Prostate tumor
descriptionThe type of positive margin involvement in prostate tumor is either extraprostatic extension (EPE) or intraprostatic (capsular incision). Margin involvement associated with EPE is diagnosed when malignant glands in extraprostatic tissue are transected by the resection margin. Intraprostatic margin involvement occurs when the urologist inadvertently develops the resection margin within the plane of the prostate rather than outside the capsule. Intraprostatic with a positive surgical margin is diagnosed when malignant glands are cut across adjacent to benign prostatic glands. In these cases, the edge of the prostate in this region is left in the patient. According to the largest series published, a significantly higher recurrence rate is found in patients with CI/intraprostatic margin involvement than in patients with organ confined disease with negative margins, or focal EPE with negative margins, although CI has a significantly better outcome than that associated with non-focal EPE and positive margins.[PMID: 17698141] This term was created for, but not limited in use to, the Royal College of Pathologists of Australasia (RCPA) Prostate cancer structured reporting protocol, 2nd edition (2014).
