| Guide for use: | Surgical margins represent sites that have either been cut or bluntly dissected by the surgeon to resect the specimen. The presence of tumour at a surgical margin is an important finding because there is the potential for residual tumour remaining in the patient in the area surrounding a positive margin. Record the code for the margin described as the closest surgical margin from the invasive or in situ carcinoma. 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 closest surgical margin for the final surgical procedure. Record for the primary tumour site only, not for metastatic sites. | ||||||||||||||||
| Collection methods: | This information should be sought from the patient's pathology report under microscopic findings. Collect this item when a person undergoes surgery for the treatment of lung cancer. | ||||||||||||||||
| Comments: | Identifying the margins involved by in situ or invasive carcinoma is useful for surgical audit. Margin involvement may influence treatment decisions and is a prognostic indicator. | ||||||||||||||||
