Omission of ALND from 40% of patients who met Z0011 criteria would have resulted in their undertreatment. ![]() Guidelines recommend irradiation of lymph node drainage stations in patients with ≥4 axillary metastatic lymph nodes. Retrospective modelling of the IBCSG 23-10 criteria reduced the percentage of patients requiring deferred surgery from 12% to 4%. Frozen section (FS) is routinely done at the time of surgery to confirm axillary metastasis and avoid unnecessary axillary lymph node dissection (ALND) in case. Utility of frozen-section analysis of sentinel lymph node biopsy specimens for melanoma in surgical decision making. Most false negatives were smaller metastases (mean 2.1 mm) and more likely in patients with infiltrating lobular carcinoma. (SLN) biopsy has emerged as an increasingly accepted staging alternative to level I and II axillary dissection. sentinel lymph nodes were sent for frozen - section examination 192 of these. In contrast, application of the IBCSG 23-10 trial criteria, found that only three patients (3.1%) had >3 positive axillary lymph nodes.įS has a low sensitivity in detecting micrometastases (19%), but a reasonable sensitivity for macrometastases (75%). Approximately 50 of sentinel lymph node operations are performed by each. Patients and Methods: Patients with breast cancer and clinically negative axillary were recruited for sentinel lymph node biopsy (SLNB). ![]() Results A total of 212 patients were included, 86 and 126 patients in the non-ALND and ALND group, respectively. Aim: This study aimed to investigate the accuracy of frozen section (FS) in diagnosis of sentinel lymph node metastasis and to analyze the predictive factors for false-negativity. However, FS has low sensitivity for detecting micro-metastases (3 positive axillary lymph nodes. Patients with false-negative frozen section in SLNB were separated by the following management of axillary lymph node dissection into non-ALND group (non-process or radiation only) and ALND group (with or without radiation). Intraoperative frozen sections (FS) of sentinel lymph nodes (SLN) were evaluated to avoid the need for deferred axillary lymph node dissection (ALND) in patients with early breast cancer (EBC). ![]()
