High-dose interleukin-2 (IL-2) is an available treatment option for patients with metastatic melanoma or renal cell carcinoma, and is associated with sustained complete and partial responses in a subset of patients. IL-2, however, is not devoid of toxicities, most of which involve the cardiovascular system and manifest as hypotension, arrhythmias, and cardiomyopathy. This report describes an unusual presentation of takotsubo cardiomyopathy in a postmenopausal woman receiving high-dose IL-2 for metastatic melanoma.

The activating BRAF mutation p.V600E has been identified in many cancers, including colon and lung adenocarcinomas, papillary thyroid cancer, malignant melanoma, and hairy cell leukemia (HCL). Malignant melanoma and HCL are of particular interest because of both the high proportion of cases harboring the mutation and the dramatic responses to BRAF inhibitor therapy reported in the literature. This report presents a patient with HCL and malignant melanoma with the BRAF p.V600E mutation, and discusses the successful treatment of both cancers with the BRAF inhibitor dabrafenib.

Over the past few years, the NCCN Guidelines for Melanoma: Cutaneous have been expanded to include pathways for treatment of microscopic satellitosis (added in v2.2020), and the following Principles sections: Molecular Testing (added in v2.2019), Systemic Therapy Considerations (added in v2.2020), and Brain Metastases Management (added in v3.2020). The v1.2021 update included additional modifications of these sections and notable revisions to Principles of: Pathology, Surgical Margins for Wide Excision of Primary Melanoma, Sentinel Lymph Node Biopsy, Completion/Therapeutic Lymph Node Dissection, and Radiation Therapy. These NCCN Guidelines Insights discuss the important changes to pathology and surgery recommendations, as well as additions to systemic therapy options for patients with advanced disease.
