Guide for use:![]() | Surgical margins represent sites that have either been cut or bluntly dissected by the surgeon to resect the specimen. Record the distance of the closest surgical margin to the invasive or in situ carcinoma as described in the pathology report. Where two or more margins are reported, only the closest should be recorded. Record only for the most definitive surgical procedure performed. For instance, if a surgical procedure to remove a portion of tumour at the primary site is followed by additional surgery to remove the remainder of the tumour at that site, code the distance of the margin for the final surgical procedure. Record for the primary tumour site only, not for metastatic sites. When the margin is described as positive (i.e. cancer cells come to the edge of the removed tissue) record "00". When surgery was not performed record "97", when it is unknown whether surgery was performed record "98", and when surgery was performed but the margin was not described record "99". |

Collection methods:![]() | This information should be sought from the patient's pathology report under microscopic findings. |
Comments:![]() | The distance of the closest margin is useful for surgical audit and for assessing the completeness of surgical resection. Margin involvement may influence treatment decisions and is a prognostic indicator. |
