A retrospective study was conducted to review the overall survival and treatment outcomes of high grade melanoma in the extremity to explore the clinical features of malignant melanoma of the hand and foot, and the therapeutic efficacies and survival rate after amputation. The clinical data of 30 patients with malignant melanoma of the hand and foot (confirmed by pathological examination), who were admitted and treated in our hospital between 2001 and 2010, were analyzed retrospectively. We analyzed variables affecting overall and disease-free survival. Thirty patients (18 men and 12 women) treated with an amputation procedure for malignant melanoma in the hand or foot constituted the study cohort. The average age of the patients at the time of diagnosis was 58.7 years. Univariate analysis for overall melanoma survival revealed that diagnosis at over 70 years of age, postoperative lymph node metastasis, and location of the tumor were significant prognostic factors. And on the Kaplan-Meier survival curve, old age, American Joint Committee on Cancer stage and postoperative lymph node metastasis showed statistically significant differences in the 5-year survival rate. Also, amputation with aggressive lymph node dissection showed improved long term survival in advanced stage melanoma. In Korean melanoma patients, for the treatment of high grade melanomas in the extremities after amputation, early diagnosis and postoperative follow-up for evaluation of lymph node metastasis are critical factors for long-term survival. And by performing lymph node dissection during amputation, we may improve the survival rate in advanced stage melanoma patients.
