Molecular biology of human melanoma development and progression

Abstract

In the United States, Australia, Northern Europe, and Canada, malignant melanoma is increasing at a faster rate than any other cancer, with the exception of lung cancer in women. Major advances have been made in the molecular biology and immunology of melanoma. These advances in basic science have led to more rational approaches to specifically targeting melanoma cells, with promising results in the clinic. An increased understanding of how melanoma spreads has led to more selective, less invasive surgical procedures that do not compromise patient health. Combinations of chemotherapy and immunotherapy are now available for patients with advanced melanoma that affect both the length and quality of the patients' lives. This review of the molecular biology of melanoma development and progression discusses the disease's etiology, molecular genetics, cell-surface antigens, experimental models, biological markers, and new forms of treatment. As we continue to learn more about malignant melanoma, we will be able to devise more specific and effective treatments that will give patients with this potentially deadly disease longer and more productive lives.
