Background:
In patients with breast cancer who choose mastectomy with immediate reconstruction, the sentinel lymph node (SLN) status on permanent histology may complicate treatment if a metastasis is found. The purpose of this study was to determine how performing an SLN biopsy (SLNB) before the definitive operation would influence subsequent surgical procedures.
Methods:
Our SLN database was searched for patients who underwent staged SLNB with subsequent mastectomy between 2001 and 2004.
Results:
Twenty-five patients with 27 breast cancers underwent SLNB before mastectomy. Of them, 9 of 27 (33%) were node positive. All 9 patients underwent modified radical mastectomy. Three node-positive patients did not undergo immediate reconstruction. Of the remaining 6 node-positive patients, 5 underwent reconstruction with autologous tissue rather than a tissue expander. In contrast, 6 of 16 (37%) node-negative patients underwent reconstruction with a tissue expander.
Conclusions:
Staged SLNB assists in selecting the appropriate operation in patients who are considering immediate reconstruction.
