Prognostic classification of malignant melanomas by combining clinical, histological, and immunohistochemical parameters.
In a retrospective study the prognostic relevance of clinical, histopathological, immunohistochemical, and flow-cytometric parameters in primary malignant melanomas was evaluated using both the receiver operating characteristic ROC procedure and the logistic regression model. The proteolytic enzymes collagenase IV, cathepsin B, and cathepsin D proved to be significant prognostic factors. Combining the results obtained with these enzymes with gender, anatomic site, tumour thickness, Clark's level, ulceration, pattern of invasive growth, and presence of large round cells resulted in greatly improved discrimination between metastasized and non-metastasized cases. It is anticipated that this method could allow for precise individual prognostic characterization and in particular for identification of high-risk patients for adjuvant therapy.
