RESUMEN
BACKGROUND: Isolated limb perfusion (ILP) is a locoregional procedure indicated by the unresectable melanoma of the limbs. Its complexity and highly demanding multidisciplinary approach means that it is a technique only implemented in a few referral centers around the globe. This report aims to examine its potential role in the era of targeted therapies and immunotherapy by conducting a systematic review of the literature on ILP. METHODS: PubMed, Embase and Cochrane Library were searched. The eligibility criteria included publications from 2000-2020 providing valid data o effectiveness, survival or toxicity. Studies in which the perfusion methodology was not clearly described, letters to the editor, non-systematic reviews and studies that applied outdated clinical guidelines were excluded. To rule out studies of a low methodological quality and assess the risk of bias, the following aspects were also required: a detailed description of the applied ILP regimen, the clinical context, follow-up periods, analyzed clinical endpoints, and the number of analyzed ILPs. The disagreements were resolved by consensus. The results are presented in tables and figures. RESULTS: Twenty-seven studies including 2637 ILPs were selected. The median overall response rate was 85%, with a median complete response rate of 58.5%. The median overall survival was 38 months, with a 5-year overall survival of 35%. The toxicity was generally mild according to Wieberdink toxicity criteria. DISCUSSION: ILP still offer a high efficacy in selected patients. The main limitation of our review is the heterogeneity and age of most of the articles, as well as the absence of clinical trials comparing ILP with other procedures, making it difficult to transfer its results to the current era. CONCLUSIONS: ILP is still an effective and safe procedure for selected patients with unresectable melanoma of the limbs. In the era of targeted therapies and immunotherapy, ILP remains an acceptable and reasonable palliative treatment alternative, especially to avoid limb amputations. The ongoing clinical trials combining systemic therapies and ILP will provide more valuable information in the future to clarify the potential synergism of both strategies.
RESUMEN
The thyroid gland is an uncommon location for metastasis. We report a 59-year-old woman with a history of cutaneous malignant melanoma. A unique hypermetabolic mass on the left thyroid lobe was identified by control F-FDG PET/CT scan, leading to dysphagia and stridor clinic. Total thyroidectomy and lymphadenectomy were performed with histopathological results concordant with metastasis from melanoma. Despite its rarity, finding focal thyroid lesions in patients with an oncological history should alert us, recommending that its metastatic etiology be ruled out.
