Muhammad Nadeem, Bijan Ansari, Caroline Osborne
Abstract
AIM: A total of 146 SLNB procedures were undertaken on 143 patients. Lymph node identification rate (IR) was 97.9%. Thirty seven patients (25.3%) were detected with cancer in their lymph nodes, 19% had at least one macrometastasis, 6% at least one micrometastasis and 1% had ITCs. The mean average lymph node retrieval was 2.2 nodes per procedure. Mild brownish discolouration was noted around the injection site. No allergic reaction or side effect of Sienna+î tracer / Magtraceî was reported. CONCLUSION: The new magnetic detection method of sentinel lymph nodes (Sentimag) is effective, feasible and comparable to the gold standard technique of sentinel lymph node biopsy in patients with breast cancer.
