The detection of V600E BRAF mutation in melanoma is fundamental since here BRAF inhibitors represent an effective treatment.,Non-V600E BRAF mutations that may also respond are not detected by certain screening methods.,Thus, knowledge about detection of these mutations is needed.,A total of 276 tumour samples from 174 melanoma patients were investigated for BRAF mutations by pyrosequencing.,Rare mutations were confirmed by capillary sequencing and compared with findings from COBAS test and immunohistochemistry using a novel BRAF antibody.,Melanoma type, localisation, and survival were summarised.,BRAF mutations were found in 43% of patients (124 tumours in 75 patients).,Among those, 14 patients (18.7%) exhibited rare mutations.,The V600EK601del and V600DK601del mutations have never been described before in melanoma.,Furthermore, V600K, V600E2, and V600D, V600G, V600R, and L597S mutations were detected.,Mutations were not detected by COBAS test in 7 out of these 14 patients and immunohistochemistry only reliably detected patients with the V600E2 and V600EK601del mutation.,Accurate diagnosis of rare BRAF mutations is crucial.,We show that pyrosequencing is accurate, highly sensitive, reliable, and time saving to detect rare BRAF mutations.,Missing these rare variant mutations would exclude a subset of patients from available effective BRAF-targeting therapy.
The incidence of melanoma is increasing worldwide, and the prognosis for patients with high-risk or advanced metastatic melanoma remains poor despite advances in the field.,A systematic literature review of treatments for advanced, metastatic disease was conducted to present the success of current treatments and the promise of those still in clinical development that may yield incremental improvements in the treatment of advanced, metastatic melanoma.,Advances in the understanding of the mechanism of chemotherapy resistance offer the hope for improved results with chemotherapy, and the triumvirate of more effective chemotherapy, immunotherapy, and targeted therapy are likely to be combined with one another for significant advances in melanoma over the coming few years.,The incidence of melanoma is increasing worldwide, and the prognosis for patients with high-risk or advanced metastatic melanoma remains poor despite advances in the field.,Standard treatment for patients with thick (≥2.0 mm) primary melanoma with or without regional metastases to lymph nodes is surgery followed by adjuvant therapy or clinical trial enrollment.,Adjuvant therapy with interferon-α and cancer vaccines is discussed in detail.,Patients who progress to stage IV metastatic melanoma have a median survival of ≤1 year.,Standard treatment with chemotherapy yields low response rates, of which few are durable.,Cytokine therapy with IL-2 achieves durable benefits in a greater fraction, but it is accompanied by severe toxicities that require the patient to be hospitalized for support during treatment.,A systematic literature review of treatments for advanced, metastatic disease was conducted to present the success of current treatments and the promise of those still in clinical development that may yield incremental improvements in the treatment of advanced, metastatic melanoma.
