Sentinel Node Location in Trunk and Extremity Melanomas: Uncommon or Multiple Lymph Drainage Does Not Affect Survival
Patients with cutaneous melanoma (CM) on the trunk have a worse prognosis than those with extremity CM. One reason could be multiple or uncommon (outside axilla or groin) sentinel node locations (SNLs). We identified 859 patients who underwent sentinel node biopsy for trunk (n = 465) or extremity (n = 394) CM in three Swedish healthcare regions from 2000 to 2008. We collected patient, tumor, and s
