Description
Abstract
Introduction. Melanoma of the skin shows a tendency to metastasize via lymph or blood secreting matrix metalloproteinases and cathepsins, which enable penetration through the dermis. Cathepsin K acts in cytoplasm of atypical melanocytes and completely cleaves internalized collagen. Materials and methods. Expression of cathepsin K was analyzed immunohistochemically in 45 melanomas and correlated to morphological and clinical parameters. Results. During six years follow up, 13 patients developed lymph node metastases and three of them distant metastases. Positive expression of cathepsin K was found in 19 cases. In univariate regression analysis histological type, pagetoid spread, mitotic activity and cathepsin K expression were significantly connected to metastases. Cathepsin K was significantly associated to histologic type, ulceration, pagetoid spread and mitotic rate. In multiple logistic regression adjusted to these variables, cathepsin K was an independent predictor in occurrence of metastases (P=0.015). Median to the occurrence of metastases was 40 months in patients with cathepsin K positive expression and 71 months in patients with cathepsin K negative expression (P<0.001). Conclusions. In this preliminary study positive expression of cathepsin K in melanoma of the skin is associated with other unfavorable prognostic factors. We consider cathepsin K expression in primary tumor would significantly precipitate occurrence of metastases.
