Abstract :
Introduction: Sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. In Iran, this procedure has not been addressed sufficiently. In this study, we report our experience in this area.Methods: Ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mCi of Tc-99m antimony sulfide colloid in two divided dose was injected around the tumor. All patients underwent surgery 2-4 hours after injection of the tracer. Patent blue V dye was also used for 8 patients. Using a hand-held gamma probe, the sentinel nodes were harvested and sent to the pathologist for frozen section and H E review. For patients with positive sentinel nodes, lymph node dissection was performed.Results: At least one sentinel node could be harvested in all patients. The mean number of sentinel nodes was 1.66. Detection rate with radiotracer and blue dye was 100% and 75% respectively. 30% of the patients had positive sentinel nodes. One patient in the pediatric age range and one head and neck melanoma were included in our study with successful sentinel node mapping.Conclusion: Sentinel lymph node biopsy using Tc-99m antimony sulfide colloid is a reliable and safe method in melanoma patients which can help in treatment planning and patient s ultimate prognosis
