A 49-year-old man initially diagnosed in 1995 with cutaneous melanoma presented to the authors’ institution in 2009 with metastatic, BRAF V600E-mutant melanoma. His treatment course to date has included surgery, adjuvant radiotherapy, and interferon, metastasectomies, granulocyte-macrophage colony-stimulating factors, a clinical trial with the BRAF inhibitor vemurafenib (PLX-4032), clinical trial with combination BRAF plus MEK inhibition with vemurafenib plus GDC-0973, and combination targeted and immune therapy with vemurafenib plus the anti-CTLA4 antibody ipilimumab. This case report illustrates the long-term management of a patient with metastatic melanoma using targeted and immune therapy, evolution in treatment guidelines, next directions in research, and the critical role of clinical trials in advancement of patient care.

Clear cell basal cell carcinoma (BCC) is an unusual variant of BCC. Its pathogenesis, prognosis, and optimal management remain poorly described due to its rarity. This report presents a 51-year-old man with a history of excised BCC and cutaneous squamous cell carcinomas of the face, with multiple recurrent poorly differentiated carcinomas with clear cell changes of the shoulder for which further classification using conventional histologic means was not possible. His tumor tissue was sent to Foundation Medicine for testing, which revealed a high number of pathogenic genomic alterations, including a mutation in PTCH1. He was diagnosed with dedifferentiated BCC and started on vismodegib. He developed lung metastases while receiving vismodegib, and his disease continued to progress while he was undergoing treatment in a phase I clinical trial. Given the high number of pathogenic alterations suggestive of high tumor mutational burden, immunotherapy was considered and off-label authorization was obtained for treatment with a PD-1 antibody (pembrolizumab). He had a dramatic disease response after 4 infusions of pembrolizumab. Molecular testing was instrumental in determining the correct diagnosis and formulating appropriate treatment options for this patient. Molecular profiling of metastatic BCCs and its subtypes is essential to the development of effective targeted therapies and combination approaches.

The NCCN Guidelines for Melanoma provide multidisciplinary recommendations on the clinical management of patients with melanoma. This NCCN Guidelines Insights report highlights notable recent updates. Foremost of these is the exciting addition of the novel agents ipilimumab and vemurafenib for treatment of advanced melanoma. The NCCN panel also included imatinib as a treatment for KIT-mutated tumors and pegylated interferon alfa-2b as an option for adjuvant therapy. Also important are revisions to the initial stratification of early-stage lesions based on the risk of sentinel lymph node metastases, and revised recommendations on the use of sentinel lymph node biopsy for low-risk groups. Finally, the NCCN panel reached clinical consensus on clarifying the role of imaging in the workup of patients with melanoma.

The NCCN Guidelines for Melanoma provide multidisciplinary recommendations for the management of patients with melanoma. These NCCN Guidelines Insights highlight notable recent updates. Dabrafenib and trametinib, either as monotherapy (category 1) or combination therapy, have been added as systemic options for patients with unresectable metastatic melanoma harboring BRAF V600 mutations. Controversy continues regarding the value of adjuvant radiation for patients at high risk of nodal relapse. This is reflected in the category 2B designation to consider adjuvant radiation following lymphadenectomy for stage III melanoma with clinically positive nodes or recurrent disease.
