Importance of lymphatic mapping in ductal carcinoma in situ (DCIS): why map DCIS?

摘要: The appropriateness of sentinel lymph node biopsy in the management patients with diagnoses ductal carcinoma situ (DCIS) or DCIS microinvasion (DCISM) has not been established. Three hundred forty-one presented a diagnosis DCISM. Two forty (70%) underwent at their definitive procedure. All clinical and pathologic data were collected prospectively. Of 224 23 (10%) upstaged to infiltrating (IDC) therapy 16 DCISM seven (44%) IDC. Excisional biopsies no more sensitive for detecting IDC than was core biopsy. Lymph metastases detected 26 195 (13%) DCIS, three 15 (20%) DCISM, eight 30 (27%) Sentinel is valuable tool treatment particularly needed those undergoing mastectomy. No "high-risk" group can be identified selective
