Systemic therapies for unresectable locoregional melanoma: a significant area of need.

Immune checkpoint inhibitors and BRAF-MEK inhibitors have revolutionized the management and prognosis of patients with metastatic melanoma. However, there is minimal evidence to guide their incorporation into current treatment paradigms for unresectable stage III disease. The era of effective systemic therapies has prompted a discussion about what constitutes unresectable disease. Patients with unresectable stage III disease can experience significant morbidity from their disease and locoregional therapies, and may progress with distant metastases. Despite increasing use of systemic therapies in unresectable stage III disease, further evidence is needed to establish their degree of benefit in this population.
