Understanding Resection Margins in Tumor Surgery
Different types of resection margins are crucial in surgical oncology, particularly in the treatment of sarcoma. Radical resections, which involve removing an entire muscular compartment, are becoming less common due to advancements in radiation therapy. Instead, wide resections, where a cuff of healthy tissue surrounding a tumor is preserved, are favored, adhering to a standard teaching of approximately two centimeters for margins, although some practitioners operate with more flexibility. Marginal resections, which only remove the tumor itself, and intralesional resections, where the tumor is excised from within the lesion, are also vital methods to consider when planning treatment.
