surgical margins assessment
Systematic evaluation of tissue boundaries around a resected tumor to determine the adequacy of cancer removal.
Full Definition
Surgical margins assessment is the pathological evaluation of tissue surrounding a resected tumor specimen to determine whether cancer cells extend to the cut edges of the specimen. This assessment is fundamental to surgical oncology as it directly impacts prognosis and the need for additional treatment. The evaluation includes gross examination of the specimen, microscopic analysis of tissue sections, and measurement of distances between tumor and specimen edges. Margin assessment requires close collaboration between surgeons and pathologists and may involve specialized techniques such as frozen section analysis during surgery.
