protoporphyrin ix has been researched along with Margins of Excision in 4 studies
protoporphyrin IX: RN given refers to parent cpd; structure in Merck Index, 9th ed, #7685
protoporphyrin : A cyclic tetrapyrrole that consists of porphyrin bearing four methyl substituents at positions 3, 8, 13 and 17, two vinyl substituents at positions 7 and 12 and two 2-carboxyethyl substituents at positions 2 and 18. The parent of the class of protoporphyrins.
Margins of Excision: The edges of tissue removed in a surgery for assessment of the effectiveness of a surgical procedure in achieving the local control of a neoplasm and the adequacy of tumor removal. When the margin is negative or not involved by tumor (e.g., CANCER) it suggests all of the tumor has been removed by the surgery.
