title: [Current biological markers of cutaneous melanoma progression].
abstract: Melanoma is the most agressive skin cancer in humans. The most important prognostic factors are the histological features of the tumor, while the clinical ones play a secondary role. Melanoma progression is characterized by the metastatic process which directly threatens the patients life. Unfortunately, routine imaging methods cannot estimate early enough this metastatic risk. Are biologic markers of cancer progression more efficient than those applied in everyday practice? Are they able to evaluate the metastatic risk and thus help the therapeutic strategy? In this review, we analysed the analytical and the clinical aspects of biologic markers of cutaneous melanoma currently available or in development. At the present time it is very difficult to distinguish one single marker of melanoma progression in the blood which correlates with the stage and the prognosis of melanoma. The most specific and sensitive enough are the melanoma associated antigens protein S-100, MIA (melanoma inhibiting activity) and the melanin precursors 5-S-cysteinyldopa and the ratio L-dopa/L-tyrosine. Tyrosinase mRNA remains the best target for the detection of circulating metastatic melanoma cells by RT-PCR. Simultaneous detection of several markers might be useful if they are carefully selected. Despite the progress in the field, more clinical studies should be performed for the development of new techniques or improvements of the existing ones for the follow-up of cutaneous melanoma.
