334 Localisation of Sentinel Node for Cutaneous Melanoma of Trunk

Abstract Aim Our aim was to review localisation of sentinel node for cutaneous melanoma of trunk based on position. This was to investigate whether we can predict sentinel node position and therefore avoid scintigram. Method We have collected 50 patients with cutaneous melanoma of the trunk who underwent sentinel node biopsy. We have reviewed and recorded position of the melanoma and most likely position of sentinel biopsy. This has been on the day of surgery compared to scintigram. Results Majority of the melanomas have drained into the predicted location. Midline melanomas had tendency to drain bilaterally. The most difficult to predict were melanomas on the anterior aspect of trunk. Conclusions In majority of cases surgeons were able to predict position of sentinel node biopsy and therefore scintigram might not be necessary. If such approach is adapted, the need for radiologist involvement on the day of surgery may decrease.
