The association between SLN metastasis size and residual axillary disease was examined. Methods: Patients undergoing SLN biopsy after NAC were identified. Omitting the intraoperative frozen-section diagnosis significantly shortened the operation time, and no case of reoperation was observed. We examined the false-negative rate of intraoperative frozen section (FS) after NAC, and the association between SLN metastasis size and residual disease at axillary lymph node dissection (ALND). There was no difference in the median hospitalization period of 2 days. We compared those groups.Īs a result, the median operation time was 65 minutes (32-112) in the omitted group and 82 minutes (35-146) in the control group, with a statistically significant difference. However, application of immunohistochemistry on frozen section of SLNB is an evolving trend in. 1 Common mapping methods for SLNB include blue dye, radioisotopes, a combination of blue dye and radioisotopes, and fluorescence imaging. Detection of micrometastasis and isolated tumor cells present a technical challenge and are associated with higher false negative rates. Its use in sentinel lymph node biopsy (SLNB) is equivocal. Studies have shown that sentinel lymph node biopsy (SLNB) has the advantages of fewer complications and less trauma than conventional axillary lymph node dissection (ALND). In those criteria, the omitted group comprised 68 patients without the intraoperative frozen-section diagnosis from January 2018 to July 2019, and the control group comprised another 68 patients with the intraoperative frozen-section diagnosis from February 2017 to January 2018. Sentinel lymph node biopsy using intraoperative frozen section, is a sensitive and specific technique of staging axilla in breast cancer patients. Purpose: Sentinel lymph node (SLN) biopsy (SLNB) is widely performed for axillary staging in patients with breast cancer. In this study, we compared for the operation time, hospitalization period, and number of reoperations between the omitted group and the control group.
In our hospital, we omit the intraoperative frozen-section diagnosis of sentinel lymph node (SLN) in these cases. The aim of this study is to prospectively review the role of sentinel lymph node (SLN) biopsy in the management of well differentiated thyroid carcinoma (WDTC), and to determine the efficacy of intraoperative frozen section analysis at detecting SLN metastasis and central compartment involvement. Among women with primary breast cancer of cTis/1/2, N0, having no preoperative chemotherapy, undergoing breast-conserving surgery and receiving whole breast irradiation and adjuvant systemic therapy, axillary lymph node dissection can be omitted for 1 or 2 sentinel lymph nodes metastasis cases.
