Sentinel lymph node biopsy in malignant melanoma: a series of 100 consecutive patients

A consecutive cohort of 100 patients who had undergone sentinel lymph node biopsy (SLNB) was analysed retrospectively. Three areas were studied: success in finding the sentinel node(s); complications of the procedure; and extra costs incurred by SLNB. The sentinel node(s) were successfully identified in 98% of the lymph node basins biopsied. The overall complication rate was 33%. The additional cost of the procedure was estimated at £1420 per patient. SLNB can reliably identify the sentinel node. However there is a significant complication rate of the technique and considerable additional costs. SLNB requires further critical evaluation before it can be accepted as a standard treatment for patients with malignant melanoma.
