Diagnosis and treatment of melanoma: European consensus-based interdisciplinary guideline
European Journal of Cancer, 2010
Cutaneous melanoma (CM) is potentially the most dangerous form of skin tumour and causes 90% of skin cancer mortality. A unique collaboration of multi-disciplinary experts from the European Dermatology Forum (EDF), the European Association of Dermato-Oncology (EADO) and the European Organization of Research and Treatment of Cancer (EORTC) was formed to make recommendations on CM diagnosis and treatment, based on systematic literature reviews and the experts' experience. Diagnosis is made clinically and staging is based upon the AJCC system. CMs are excised with one to two centimetre safety margins. Sentinel lymph node dissection (SLND) is routinely offered as a staging procedure in patients with tumours more than 1 mm in thickness, although there is as yet no clear survival benefit for this approach. Interferon-a treatment may be offered to patients with stage II and III melanoma as 0959-8049/$ -see front matter Ó

Cutaneous melanoma (CM) is potentially the most dangerous form of skin tumour and causes 90% of skin cancer mortality. A unique collaboration of multidisciplinary experts from the European Dermatology Forum, the European Association of Dermato-Oncology and the European Organization of Research and Treatment of Cancer was formed to make recommendations on CM diagnosis and treatment, based on systematic literature reviews and the experts' experience. Diagnosis is made clinically and staging is based upon the AJCC system. CMs are excised with one to two centimetre safety margins. Sentinel lymph node dissection is routinely offered as a staging procedure in patients with tumours more than one millimetre in thickness, although there is as yet no resultant survival benefit. Interferon-α treatment can be offered to patients with more than 1.5 millimetre in thickness and stage II to III melanoma as an adjuvant therapy, as this treatment increases the relapse free survival. The lack of a clear survival benefit and the presence of toxicity however limit its use in practice. In distant metastasis, all options of surgical therapy have to be considered thoroughly. In the absence of surgical options, systemic medical treatment is indicated, but with, to date, low response rates. Therapeutic decisions should be made by the melanoma team and the informed patient after full discussion of the options.
Diagnosis and treatment protocols of cutaneous melanoma: latest approach 2010
Chirurgia (Bucharest, Romania : 1990)
Cutaneous melanoma is the most aggressive skin malignancies with increasing rate of incidence in the latest decades. New imaging technique plays an important role in melanoma management: dermoscopy and computer dermoscopy, ultrasound, MRI, CT, PET and PET/CT. Due to the dermoscopy and lesion diagnosis in early stages the increasing number of curative melanoma are registered. Sentinel lymph node biopsy became a compulsory phase for patients with tumor thickness > 1 mm. Serological biomarkers proved to be a necessary investigation for melanoma diagnosis, follow-up and treatment response. Current TNM melanoma staging is based on AJCC classification since 2001 witch includes new elements like histopathologic ulceration in stage I and II and lymph node micro- and macrometastases in stage III. Treatment protocols include surgical tumor excision with only 1-2 cm safety margins and radical lymphadenectomy is performed after positive sentinel lymph node biopsy. The adjuvant treatment in a...
Cochrane Database of Systematic Reviews, 2015
Background Melanoma is the leading cause of skin cancer-associated mortality. The vast majority of newly diagnosed melanomas are confined to the primary cutaneous site. Surgery represents the mainstay of melanoma treatment. Treatment strategies include wide excision of the primary tumour and sentinel lymph node biopsy (SLNB) to assess the status of the regional nodal basin(s). SLNB has become an important component of initial melanoma management providing accurate disease staging. Objectives To assess the effects and safety of SLNB followed by completion lymph node dissection (CLND) for the treatment of localised primary cutaneous melanoma. Search methods We searched the following databases up to February 2015: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2015, Issue 1), MEDLINE (from 1946), EMBASE (from 1974), and LILACS ((Latin American and Caribbean Health Science Information database, from 1982). We also searched the following from inception: African Index Medicus, IndMED of India, Index Medicus for the South-East Asia Region, and six trials registers. We checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials (RCTs). We searched ISI Web of Science Conference Proceedings from inception to February 2015, and we scanned the abstracts of major dermatology and oncology conference proceedings up to 2015. Selection criteria Two review authors independently assessed all RCTs comparing SLNB followed by CLND for the treatment of primary localised cutaneous melanoma for inclusion. Primary outcome measures were overall survival and rate of treatment complications and side effects. Data collection and analysis Two review authors independently extracted and analysed data on survival and recurrence, assessed risk of bias, and collected adverse effect information from included trials. Main results We identified and included a single eligible trial comparing SLNB with observation which was published in eight different reports (from 2005 to 2014) with 2001 participants. This trial did not report on our first primary outcome of overall survival (which was also the planned primary outcome of this trial). When contacted for this important data, the trial authors stated “there are numerous additional analyses that have yet to be reported for the trial”. We were able however to estimate overall survival from data included in the appendix of the published report and found no evidence of benefit for SLNB for overall survival. The overall survival hazard ratio (HR) using ITT (intention-to-treat) analysis was 0.99 95% confidence interval [CI] 0.82 to 1.19, 1661 participants). The overall survival using ITT for intermediate thickness melanomas was (HR 0.92, 95% CI 0.73 to 1.16) and for thick melanomas it was (HR 1.15, 95% CI 0.82 to 1.61). The study did report on our second primary outcome of rate of treatment complications: short-term surgical morbidity (30 days) in 1735 participants showed no difference between SLNB and observation (risk ratio [RR] 1.11, 955 CI 0.9 to 1.37) for wide excision of the tumour site but favoured observation for complications related to the regional nodal basin (RR 14.36, 95% CI 6.74 to 30.59). Our secondary outcomes of disease-specific and disease-free survival, local recurrence and distant metastases were reported. There were 1347 participants in the intermediate-thickness melanoma group and 314 in the thick melanoma group.The study did not report the actual 10-year melanoma-specific survival rate for all included participants. Instead, melanoma-specific survival rates for each group of participants: intermediate-thickness melanoma (defined as 1.2 to 3.5 mm) and thick melanomas (defined as 3.50 mm or more) was reported. In the intermediate-thickness melanoma group there was no statistically significant difference in disease-specific survival between study groups at 10 years (81.4 ± 1.5% versus 78.3 ± 2.0%, HR 0.84, 95% CI 0.65 to 1.09). In the thick melanoma group, again there was no statistically significant difference in disease-specific survival between study groups at 10 years (58.9.3 ± 4.1% versus 64.4 ± 4.6%, HR 1.12, 95% CI 0.77 to 1.64). Combining these groups there was some heterogeneity (I2 = 34%) but the total HR was not statistically significant (HR 0.92, 95% CI 0.74 to 1.14). The summary estimate for disease-free survival at 10 years favoured SLNB over observation in participants with intermediate-thickness and thick melanomas (HR 0.75, 95% CI 0.63 to 0.89). With regard to the rate of local and regional recurrence as the site of first recurrence, a benefit of SLNB uniformly existed in both groups of participants with intermediate-thickness and thick melanomas (RR 0.56, 95% CI 0.45 to 0.69). This is in contrast with a uniformly unfavourable effect of SLNB with regard to the rate of distant metastases as site of first recurrence, in both groups of participants with intermediate-thickness and thick melanomas (HR 1.33, 95% CI 1.03 to 1.72). Authors’ conclusions We found no evidence of improved overall survival or melanoma-specific survival rates for participants with intermediate or thick melanomas who underwent SLNB compared with observation alone. Disease-free survival and rate of local and regional recurrence favoured SLNB in both groups of participants with intermediate-thickness and thick melanomas but short-term surgical morbidity was higher in the SLNB group, especially with regard to complications in the nodal basin. The evidence for the outcomes of interest in this review is of low quality due to the risk of bias and imprecision of the estimated effects. Further research may have an important impact on our estimate of the effectiveness of SLNB in managing primary localised cutaneous melanoma. Currently this evidence is not sufficient to document a benefit of SLNB when compared to observation in individuals with primary localised cutaneous melanoma.
Update and Review on the Surgical Management of Primary Cutaneous Melanoma
Healthcare, 2014
The surgical management of malignant melanoma historically called for wide excision of skin and subcutaneous tissue for any given lesion, but has evolved to be rationally-based on pathological staging. Breslow and Clark independently described level and thickness as determinant in prognosis and margin of excision. The American Joint Committee of Cancer (AJCC) in 1988 combined features from each of these histologic classifications, generating a new system, which is continuously updated and improved. The National Comprehensive Cancer Network (NCCN) has also combined several large randomized prospective trials to generate current guidelines for melanoma excision as well. In this article, we reviewed: (1) Breslow and Clark classifications, AJCC and NCCN guidelines, the World Health Organization's 1988 study, and the Intergroup Melanoma Surgical Trial; (2) Experimental use of Mohs surgery for in situ melanoma; and (3) Surgical margins and utility and indications for sentinel lymph node biopsy (SLNB) and lymphadenectomy. Current guidelines for the surgical management of a primary melanoma of the skin is based on Breslow microstaging and call for cutaneous margins of resection of 0.5 cm for MIS, 1.0 cm for melanomas ≤1.0 mm thick, 1-2 cm for melanoma thickness of 1.01-2 mm, 2 cm OPEN ACCESS Healthcare 2014, 2 235 margins for melanoma thickness of 2.01-4 mm, and 2 cm margins for melanomas >4 mm thick. Although the role of SLNB, CLND, and TLND continue to be studied, current recommendations include SLNB for Stage IB (includes T1b lesions ≤1.0 with the adverse features of ulceration or ≥1 mitoses/mm 2) and Stage II melanomas. CLND is recommended when sentinel nodes contain metastatic deposits.
FROM THE ACADEMY Guidelines of care for the management of primary cutaneous melanoma
The incidence of primary cutaneous melanoma has been increasing dramatically for several decades. Melanoma accounts for the majority of skin cancererelated deaths, but treatment is nearly always curative with early detection of disease. In this update of the guidelines of care, we will discuss the treatment of patients with primary cutaneous melanoma. We will discuss biopsy techniques of a lesion clinically suspicious for melanoma and offer recommendations for the histopathologic interpretation of cutaneous melanoma. We will offer recommendations for the use of laboratory and imaging tests in the initial workup of patients with newly diagnosed melanoma and for follow-up of asymptomatic patients. With regard to treatment of primary cutaneous melanoma, we will provide recommendations for surgical margins and briefly discuss nonsurgical treatments. Finally, we will discuss the value and limitations of sentinel lymph node biopsy and offer recommendations for its use in patients with primary cutaneous melanoma. (J Am Acad Dermatol 2011;65:1032-47.) DISCLAIMER Adherence to these guidelines will not ensure successful treatment in every situation. Furthermore, these guidelines should not be interpreted as setting a standard of care, or be deemed inclusive of all proper methods of care nor exclusive of other methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific therapy must be made by the physician and the patient in light of all the circumstances presented by the individual patient, and the known variability and biological behavior of the disease. This guideline reflects the best available data at the time the guideline was prepared.

Background For patients who are diagnosed with early-stage cutaneous melanoma, the principal therapy is wide surgical excision of the primary tumour and assessment of lymph nodes. The purpose of the present guideline was to update the 2010 Cancer Care Ontario guideline on wide local excision margins and sentinel lymph node biopsy (SLNB), including treatment of the positive sentinel node, for melanomas of the trunk, extremities, and head and neck.Methods Using Ovid, the MEDLINE and EMBASE electronic databases were systematically searched for systematic reviews and primary literature evaluating narrow compared with wide excision margins and the use of SLNB for melanoma of the truck and extremities and of the head and neck. Search timelines ran from 2010 through week 25 of 2017.Results Four systematic reviews were chosen for inclusion in the evidence base. Where systematic reviews were available, the search of the primary literature was conducted starting from the end date of the se...
