intralesional excision
Surgical removal that cuts through tumor tissue, resulting in incomplete removal with high risk of local recurrence.
Full Definition
Intralesional excision represents the most limited form of tumor removal, where the surgical plane passes directly through tumor tissue rather than through surrounding normal tissue. This approach results in gross contamination of the surgical field with tumor cells and virtually guarantees incomplete removal. While intralesional excision may be appropriate for certain benign lesions requiring debulking or for palliative procedures in advanced malignancies, it is inadequate for curative treatment of most bone tumors. The high risk of local recurrence associated with intralesional excision makes it unsuitable for primary treatment of malignant bone tumors.
