ResumoincidenceThe incidence of malignant melanoma varies from 3–5/100 000/year in Mediterranean countries to 12–20/100 000/year in Nordic countries. The mortality rate is 2/100 000/year for females and 3/100 000/year for males with a lesser variation with geography. Melanoma mortality has doubled in males over the last 25 years, during which time a trend of declining incidence and mortality in high-risk Northern European countries combined with a continuing increase in Southern Europe has emerged [1.MacKie R.M. Bray C. Vestey J. et al.Melanoma incidence and mortality in Scotland 1979–2003.Br J Cancer. 2007; 96: 1772-1777Crossref PubMed Scopus (100) Google Scholar]. Increased ultraviolet-B ray exposure of a genetically predisposed population seems responsible for an ongoing increase in incidence over recent decades [2.de Vries E. Bray F.I. Coebergh J.W. Parkin D.M. Changing epidemiology of malignant cutaneous melanoma in Europe 1953–1997: rising trends in incidence and mortality but recent stabilizations in western Europe and decreases in Scandinavia.Int J Cancer. 2003; 107: 119-126Crossref PubMed Scopus (322) Google Scholar].diagnosisSuspicious lesions are characterized by asymmetry, border irregularities, color heterogeneity, dynamics (dynamics in colors, elevation or size) (the ABCD rule) [3.Garbe C. Hauschild A. Volkenandt M. et al.Evidence-based and interdisciplinary consensus-based German guidelines: systemic medical treatment of melanoma in the adjuvant and palliative setting.Melanoma Res. 2008; 18: 152-160Crossref PubMed Scopus (54) Google Scholar]. Today, many primary melanomas have a diameter of <5 mm [4.Bono A. Tolomio E. Trincone S. et al.Micro-melanoma detection: a clinical study on 206 consecutive cases of pigmented skin lesions with a diameter ≤3 mm.Br J Dermatol. 2006; 155: 570-573Crossref PubMed Scopus (62) Google Scholar] [B].Diagnosis should be based on a full thickness excisional biopsy with a small side margin. Dermoscopy performed by an experienced examiner can improve the diagnostic accuracy.Processing by an experienced pathology institute is mandatory.The histology report should follow the World Health Organization (WHO) classification and include maximum thickness in millimeters (Breslow), level of invasion (Clark, level I–V), presence of ulceration, presence and extent of regression and clearance of the surgical margins.stagingPhysical examination with special attention to other suspicious pigmented lesions, tumor satellites, in-transit metastases, and to signs or symptoms suggestive of regional lymph node and systemic metastases is mandatory.In low-risk melanomas (tumor thickness 1 mm provides more accurate staging information, particularly for lesions of intermediate thickness (1–4 mm) but has no therapeutic value as it did not result in overall survival benefits. It may be followed by complete clearance of regional lymph nodes if the sentinel node was positive for micro metastases [C]. However, this procedure has no proven effect on overall survival [8.Morton D.L. Thompson J.F. Cochran A.J. et al.Sentinel-node biopsy or nodal observation in melanoma.N Engl J Med. 2006; 355: 1307-1317Crossref PubMed Scopus (1471) Google Scholar, 9.Rosenberg S.A. Why perform sentinel-lymph-node biopsy in patients with melanoma?.Nat Clin Pract Oncol. 2008; 5: 1Crossref PubMed Scopus (21) Google Scholar]. Sentinel lymph node biopsy should be performed only by skilled teams in experienced centres, with appropriate balanced consideration of potential morbidity versus benefit.There is no generally accepted adjuvant therapy to date for patients with high-risk primary melanoma or completely resected lymph node metastases (stage III). Given the absence of consistent, significant benefit in overall survival from any therapy, patient enrolment in clinical trials should be encouraged. Adjuvant immunotherapy with interferon α leads to a significant prolongation of disease-free survival in some, but not all, randomized trials. Several large independent trials using intermediate dose (or pegylated interferon) have demonstrated a positive effect on disease-free and distant metastases-free survival in patients with micrometastases (N1a) [10.Eggermont A.M. M S.S. Santinami M. Kruit W. et al.EORTC Melanoma Group.

Adjuvant treatment in patients with resected macroscopic involvement (N1b) is preferentially applied in the context of randomized clinical trials in specialized centres.Adjuvant chemotherapy, mistletoe extracts, viscum album and hormone therapies are not beneficial [11.Kleeberg U.R. Suciu S. Broecker E.B. et al.Final results of the EORTC 18871/DKG 80–1 randomised phase III trial: rIFN-alpha 2b versus rIFN-gamma versus ISCADOR M versus observation after surgery in melanoma patients with either high-risk primary (thickness >3 mm) or regional lymph node metastasis.Eur J Cancer. 2004; 40: 390-402Abstract Full Text Full Text PDF PubMed Scopus (183) Google Scholar, 12.Eigentler T.K.

Adjuvant immunotherapy with other cytokines including interleukin-2, tumor vaccination, and immunochemotherapy are experimental and not to be used outside of controlled clinical trials.Radiotherapy for local tumor control should be considered in case of inadequate resection margins of lentigo maligna melanoma [13.Farshad A. Burg G. Panizzon R. Dummer R. A retrospective study of 150 patients with lentigo maligna and lentigo maligna melanoma and the efficacy of radiotherapy using Grenz or soft X-rays.Br J Dermatol. 2002; 146: 1042-1046Crossref PubMed Scopus (152) Google Scholar] or R1 resections of melanoma metastases when re-excision is not feasible [B].treatment for locoregional metastatic diseaseIn the case of isolated locoregional lymph node metastases, surgical removal, including the surrounding lymph node region, is indicated; removal of the tumor-bearing lymph node alone is insufficient [14.AustralianCancerNetwork Guidelines for the management of cutaneous melanoma. Stone Press, Sydney1997Google Scholar]. Surgical removal is also recommended in the case of an isolated metastasis in a parenchymal organ, including the central nervous system. However, before undertaking additional aggressive local surgical treatments, a detailed staging investigation, including imaging techniques such as computed tomography (CT) or positron emission tomography (PET) scans, are necessary to exclude the presence of further metastases [3.Garbe C. Hauschild A. Volkenandt M. et al.Evidence-based and interdisciplinary consensus-based German guidelines: systemic medical treatment of melanoma in the adjuvant and palliative setting.Melanoma Res. 2008; 18: 152-160Crossref PubMed Scopus (54) Google Scholar] [B].Non-resectable-transit metastases or inoperable primary tumors of the limbs without additional metastases may be treated with isolated limb perfusion using e.g. melphalan and tumor necrosis factor [II–III, C]. However, such treatment requires major surgery and should be restricted to a few experienced centres. Radiation therapy may be used instead [V, D], although there are no data showing a positive effect on any outcome measure.Adjuvant systemic therapy after complete resection as mentioned above.treatment for systemic metastatic disease (stage IV AJCC)Palliative therapy for advanced disease with several metastases in different anatomical regions should initially use well tolerated single-agent cytotoxic chemotherapy such as dacarbazine, temozolomide, as any systemic therapy did not result in survival prolongation but symptom palliation only [15.Huncharek M. Caubet J.F. McGarry R. Single-agent DTIC versus combination chemotherapy with or without immunotherapy in metastatic melanoma: a meta-analysis of 3273 patients from 20 randomized trials.Melanoma Res. 2001; 11: 75-81Crossref PubMed Scopus (143) Google Scholar, 16.Kaufmann R. Spieth K. Leiter U. et al.Temozolomide in combination with interferon-alfa versus temozolomide alone in patients with advanced metastatic melanoma: a randomized, phase III, multicenter study from the Dermatologic Cooperative Oncology Group.J Clin Oncol. 2005; 23: 9001-9007Crossref PubMed Scopus (99) Google Scholar] [C]. Fit patients with high-volume visceral metastatic disease who need rapid symptom palliation may be treated with combination chemotherapy or combinations of chemotherapy with cytokines in view of the superior response rates reported in some trials. However, this activity comes at the price of increased toxicity and is not associated with survival prolongation [17.Verma S. Petrella T. Hamm C. et al.the members of the Melanoma Disease Site Group of Cancer Care Ontario's Program in Evidence-based Care. Biochemotherapy for the treatment of metastatic malignant melanoma: a clinical practice guideline.Curr Oncol. 2008; 15: 85-89Crossref PubMed Scopus (1) Google Scholar]. Since there is no impact of systemic therapy on survival in advanced melanoma patients, they should be preferentially treated in controlled clinical trials evaluating new approaches (combination chemotherapy with new agents, cytokines, targeted agents, immunotherapeutic approaches). Surgery of visceral metastases may be appropriate for selected cases with good performance status and isolated tumor manifestation. In all surgically treated patients in principal R0-resections are the goal.Palliative radiotherapy should be considered especially for symptomatic brain or localized bone metastases.patient information and follow-upThe patient should be instructed to avoid sun burns, extended unprotected solar or artificial ultraviolet exposure and be advised for lifelong regular self-examination of the skin and peripheral lymph nodes. The patient must be made aware that family members are at an increased melanoma risk [B].During melanoma follow-up, patients are clinically monitored in order to detect a relapse and to recognize additional skin tumors, especially a second melanoma, as early as possible [3.Garbe C. Hauschild A. Volkenandt M. et al.Evidence-based and interdisciplinary consensus-based German guidelines: systemic medical treatment of melanoma in the adjuvant and palliative setting.Melanoma Res. 2008; 18: 152-160Crossref PubMed Scopus (54) Google Scholar] [B]. Eight per cent of all melanoma patients develop a secondary melanoma within 2 years of their initial diagnosis [18.Titus-Ernstoff L. Perry A.E. Spencer S.K. et al.Multiple primary melanoma: two-year results from a population-based study.Arch Dermatol. 2006; 142: 433-438Crossref PubMed Scopus (80) Google Scholar]. Melanoma patients also have increased risks for other skin tumors. In patients with lentigo maligna melanomas, 35% develop another cutaneous malignancy within 5 years [14.AustralianCancerNetwork Guidelines for the management of cutaneous melanoma. Stone Press, Sydney1997Google Scholar].However, there is currently no consensus on the frequency of follow-up and the use of imaging techniques. Typically patients will be seen every 3–6 months during the first 3 years and every 6–12 months thereafter. This recommendation is based on the relapse-risk profile over time, with less frequent visits being required for patients with thinner localised melanomas.The follow-up should be prognosis-oriented and include psychological care for the patients. Since patients with a thin primary melanoma have only a small risk of relapse, imaging techniques are not necessary for this patient population. Ultrasound of lymph nodes, CT or whole body PET/PET-CT scans may be used in the follow-up of patients with thick primary tumors or following treatment of metastases. However, as no effective salvage therapy is available to date, these investigations rarely lead to early diagnosis and surgical salvage of occasional patients with solitary metastases, with the exception of participation in clinical trials of experimental therapies.noteLevels of Evidence [I–V] and Grades of Recommendation [A–D] as used by the American Society of Clinical Oncology are given in square brackets.

In higher stages imaging of nodal basin, chest/abdomen/pelvis is recommended in order to allow proper staging.The refined version of the American Joint Comittee on Cancer (AJCC) staging and classification system, which includes the staging of microscopically positive lymph nodes, is the classification system of choice [5.Balch C.M.

Hamm C. et al.the members of the Melanoma Disease Site Group of Cancer Care Ontario's Program in Evidence-based Care. Biochemotherapy for the treatment of metastatic malignant melanoma: a clinical practice guideline.Curr Oncol. 2008; 15: 85-89Crossref PubMed Scopus (1) Google Scholar]. Since there is no impact of systemic therapy on survival in advanced melanoma patients, they should be preferentially treated in controlled clinical trials evaluating new approaches (combination chemotherapy with new agents, cytokines, targeted agents, immunotherapeutic approaches). Surgery of visceral metastases may be appropriate for selected cases with good performance status and isolated tumor manifestation. In all surgically treated patients in principal R0-resections are the goal. Palliative radiotherapy should be considered especially for symptomatic brain or localized bone metastases. patient information and follow-upThe patient should be instructed to avoid sun burns, extended unprotected solar or artificial ultraviolet exposure and be advised for lifelong regular self-examination of the skin and peripheral lymph nodes. The patient must be made aware that family members are at an increased melanoma risk [B].During melanoma follow-up, patients are clinically monitored in order to detect a relapse and to recognize additional skin tumors, especially a second melanoma, as early as possible [3.Garbe C. Hauschild A. Volkenandt M. et al.Evidence-based and interdisciplinary consensus-based German guidelines: systemic medical treatment of melanoma in the adjuvant and palliative setting.Melanoma Res. 2008; 18: 152-160Crossref PubMed Scopus (54) Google Scholar] [B]. Eight per cent of all melanoma patients develop a secondary melanoma within 2 years of their initial diagnosis [18.Titus-Ernstoff L. Perry A.E. Spencer S.K. et al.Multiple primary melanoma: two-year results from a population-based study.Arch Dermatol. 2006; 142: 433-438Crossref PubMed Scopus (80) Google Scholar]. Melanoma patients also have increased risks for other skin tumors. In patients with lentigo maligna melanomas, 35% develop another cutaneous malignancy within 5 years [14.AustralianCancerNetwork Guidelines for the management of cutaneous melanoma. Stone Press, Sydney1997Google Scholar].However, there is currently no consensus on the frequency of follow-up and the use of imaging techniques. Typically patients will be seen every 3–6 months during the first 3 years and every 6–12 months thereafter. This recommendation is based on the relapse-risk profile over time, with less frequent visits being required for patients with thinner localised melanomas.The follow-up should be prognosis-oriented and include psychological care for the patients. Since patients with a thin primary melanoma have only a small risk of relapse, imaging techniques are not necessary for this patient population. Ultrasound of lymph nodes, CT or whole body PET/PET-CT scans may be used in the follow-up of patients with thick primary tumors or following treatment of metastases. However, as no effective salvage therapy is available to date, these investigations rarely lead to early diagnosis and surgical salvage of occasional patients with solitary metastases, with the exception of participation in clinical trials of experimental therapies.
