Abstract
BACKGROUND/AIM: The aim of this study was to evaluate the current role of frozen section in identifying patients who could benefit from an immediate axillary lymph node dissection (ALND), following the criteria of the ASOCOG Z0011 and IBCSG 23-10 trials. PATIENTS AND METHODS: A retrospective review was performed involving 2,079 patients with early breast cancer who underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. RESULTS: Sensitivity and diagnostic accuracy were 63.8% and 90.3%, respectively. Sensitivity was significantly higher (p<0.001) in finding macrometastases (81.8%) compared to micrometastases (11.9%). Frozen section was useful only in 7.7% of the patients who met the criteria of the IBCSG 23-01 and ACOSOG Z0011 trials. CONCLUSION: Frozen section continues to be very useful in the intraoperative assessment of the SLN, offering a high sensitivity and diagnostic accuracy. Omission of ALND in 24.4% of patients who met the ACOSOG Z0011 criteria would have resulted in their undertreatment. Copyright
