Sentinel lymph node biopsy in operations for recurrent breast cancer

Abstract 

Background

In a pilot prospective consecutive series on 50 patients with recurrent breast cancer, results of sentinel lymph node biopsy (SLNB) are reported. The interval between primary operation and recurrence was 8years (range 1–18years). Only three patients had not undergone dissection of the axilla (ALND).

Results

In 51% of patients scintigraphy disclosed sentinel nodes (SN). At operation SN was identified in 45% of patients corresponding to 83% of the SN's visualized by the scintigraphy. SN contained metastases in seven cases (16%), and the treatment plan was changed as a consequence of the SN examination.

Conclusion

SLNB can identify SN at a high rate, and the findings may influence further planning of treatment. SLNB should be a future standard procedure in operations for recurrent breast cancer. Next step should be a randomized study.
