|
Purpose: To evaluate treatment outcomes of malignant melanoma and to analyze the factors that contributes to outcomes.
Materials and Methods : We reviewed the 51 cases of malignant melanoma from March, 1997 to March, 2004 and were followed up more than 5 years. Average age was 49.4. We compared 5-year survival rate for each age, gender, site of occurrence, depth of tumor, metastasis of regional lymph node and immuno-chemo therapy.
Results: 5-year survival rate was 88.5% for the age group below 65, 88.0% for the age group 65 and above, 62.5% for male and 100% for female. 5-year survival rate for the site of occurrence showed 100% in upper extremities, and 80.0% in lower extremities and 100% in other sites. 5-year survival rate was 100% for the stage below Clark stage III and 79.3% for the stage above IV. In surgical resection, 5-year survival rate was 66.7% for lymph node metastasis group and 94.9% for non-lymph node metastasis group.
Conclusion: The prognostic factors of malignant melanoma were gender, tumor site, depth of tumor (Clark’s stage) and metastasis of regional lymph node. But, there was no relation between the age and the survival rate in our study.
