Purpose:This study was designed to evaluate the treatment results of malignant melanoma and to analyze the factors influencing prognosis.
Materials and Methods :Thirty one cases of malignant melanoma were included in this study. They were treated in our hospital surgically, medically and immunologically from January 1996 to December 2005, and were followed more than 5 years. We compared 5 year survival rate (5YSR) according to the age, gender, anatomical site, depth of tumor, TNM stage, involvement of lymph node and immuno-chemotherapy.
Results:Overall 5YSR was 80.6%. 5YSR of the age group below 65 years was 89.7% and 66.7% for the age group over 65 (p=0.033). 5YSR for men was 75% and 90.9% for women. 5YSR according to the site of occurrence showed 66.7% in upper extremities, 89.5% in lower extremities, and 66.7% in other site. 5YSR was 100% for the Clark level below III and 62.5% for the level above IV (p=0.032). 5YSR was 53.8% for lymph node metastasis group and 100% for non-lymph node metastasis group (p=0.021).
Conclusion:We concluded that early diagnosis and wide excision was the most important in treatment of malignant melanoma. The prognostic fractors of malignant melanoma were age, depth of tumor (Clark’s stage) and metastasis of lymph node.
