Abstract

Background Lymphedema can occur in patients undergoing axillary lymph node dissection (ALND) and radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed to decrease the risk of lymphedema in patients after ALND. Some patients who ultimately require ALND are candidates for attempted sentinel lymph node biopsy (SLNB) or targeted axillary excision. In those scenarios, ALND can be performed (1) immediately if frozen sections are positive or (2) as a second operation following permanent pathology. The purpose of this study is to evaluate immediate ALND/ILR following positive intraoperative frozen sections to guide surgical decision-making and operative planning.

Methods A single-center retrospective review was performed (2019–2022) for breast cancer patients undergoing axillary node surgery with breast reconstruction. Patients were divided into two groups: immediate conversion to ALND/ILR (Group 1) and no immediate conversion to ALND (Group 2). Demographic data and operative time were recorded.

Results There were 148 patients who underwent mastectomy, tissue expander (TE) reconstruction, and axillary node surgery. Group 1 included 30 patients who had mastectomy, sentinel node/targeted node biopsy, TE reconstruction, and intraoperative conversion to immediate ALND/ILR. Group 2 had 118 patients who underwent mastectomy with TE reconstruction and SLNB with no ALND or ILR. Operative time for bilateral surgery was 303.1 ± 63.2 minutes in Group 1 compared with 222.6 ± 52.2 minutes in Group 2 (p = 0.001). Operative time in Group 1 patients undergoing unilateral surgery was 252.3 ± 71.6 minutes compared with 171.3 ± 43.2 minutes in Group 2 (p = 0.001).

Conclusion Intraoperative frozen section of sentinel/targeted nodes extended operative time by approximately 80 minutes in patients undergoing mastectomy with breast reconstruction and conversion of SLNB to ALND/ILR. Intraoperative conversion to ALND adds unpredictability to the operation as well as additional potentially unaccounted operative time. However, staging ALND requires an additional operation.
