The treatment of patients with metastasizing melanoma, still one of the most deadly diseases in modern medicine, ranks among the greatest challenges that a clinician has to face. Metastatic melanoma also is one of the most profound sources of clinical frustration, since it provides far more ultimately defeating experiences than clinical victories. At the same time, the fascinating biology of melanoma has invited the study of this neuroectodermal tumor as a model system for dissecting many of the key problems of modern oncology, ranging from molecular oncogenesis via the controls of tumor proliferation, apoptosis, invasion, metastasis, and angiogenesis to tumor immunosurveillance and tumor drug resistance. Together with the dire need to develop more effective treatment modalities for improving both life expectancy and quality of life of affected patients, this has made metastatic melanoma a favorite model
Viewpoint 1Melanoma is one of the tumors that most frequently metastasizes to regional lymphnodes and to distant sites. The high degree of malignancy and the poor final outcome correlated with this disease has strongly stimulated in the past decades many studies and clinical trials to help defining the most suitable therapy in these cases. Even though in the area of treatment of nodal metastases important innovations have been introduced in the recent past, for distant metastases, no convincing solution is available at the moment.
439for the exploration of innovative strategies for tumor management. Encouragingly, many of these have already generated very promising results in animal models. However, this impressive level of research progress in conquering melanoma in the animal room contrasts rather pitifully with the actual progress made on the ward. This CONTROVERSIES feature, therefore, critically and soberly reviews the state of the art of treating metastatic melanoma today (distinguishing between nodal and distant metastases), and sharply defines unresolved or comparatively neglected key problems. In addition, this feature highlights several novel, provocative, hitherto underappreciated, yet potentially promising treatment approaches that deserve systematic exploration. Hopefully, this will offer further inspiration for the design and pursuit of innovative anti-melanoma strategies off-the-beaten-track.
How to treat nodal melanoma metastases todaySurgery remains the only effective option for treating nodal metastases from cutaneous melanoma since chemotherapy and radiotherapy do not achieve the same cure in patients with nodal disease. However the indication for performing an elective lymph node dissection (ELND) or a delayed one (DLND) is contested (1-8).The supporters of ELND invoke the following arguments: 1) the significant incidence of silent
