ABSTRACT
BACKGROUND:
To analyse the patient-related, disease-related and treatment-related factors in a group of melanoma patients to assess their impact on iliac metastasis and on overall survival.METHODS:
Medical records of thirty-nine patients with lower extremity malignant melanoma were retrospectively reviewed to confirm all of the clinical data. Age and gender were recorded as patient-related factors. Tumor location, size, histology, ulceration status, and TNM stage, Breslow thickness, Clark level, presence of inguinal LN metastases, and locoregional metastases (local recurrences, in transit metastases and regional LN metastases) were evaluated as disease-related factors. Type of surgery (en block excision of primary tumor, en block excision of primary tumor and inguinal lymph node dissection, en block excision of primary tumor and ilioinguinal lymph node dissection) and postoperative chemotherapy were taken into account as treatment-related factors.RESULTS:
The presence of inguinal lymph node metastases was significantly associated with iliac metastasis (p = 0.015). Tumor size (p = 0.046), tumor TNM stage (p = 0.009), Breslow thickness (p = 0.033), Clark level (p = 0.029), presence of in transit metastases (p = 0.010) and postoperative chemotherapy (p = 0.002) has been related to impaired overall survival rate.CONCLUSIONS:
Therapeutic lymph node dissection appears to carry a small but definite therapeutic benefit. Selection of appropriate patients for the more extensive procedure would be ideal, but at present there are no well proven selection criteria. The authors advocate therapeutic dissection when the inguinal lymph nodes are involved.
