Hello all. My husband recently had surgery to remove a 1.1 mm non-ulcerated melanoma on his leg - WLE and SNB (groin). Very few cells (approx. 10) were found microscopically in the sentinel node. PET was clear. Stage IIIA - T2a, N1a, M0. Now the decision is whether or not to do a full regional lymph node dissection in the next couple of weeks. The medical oncologist says the odds are low (6-10%) that the other nodes are cancerous, but since he is in good health and relatively young (48) it might be worthwhile to do the full groin excision. The surgical oncologist doesn't think the risks (lymphedema, etc.) outweigh the benefit.
If anyone else who experienced this situation would share their experience and outcome we would appreciate it.
