A new frontier in treatment of advanced melanoma: Redefining clinical management in the era of immune checkpoint inhibitors.

Immune checkpoint inhibitors have revolutionized treatment of advanced cutaneous melanoma. This group of novel therapeutic agents differs from other systemic treatments and has necessitated a new approach for several fundamental aspects of clinical practice in oncology. Marked differences in outcomes associated with immune checkpoint inhibitors compared with other systemic therapies has required a new paradigm for prognostication in the setting of advanced melanoma. Distinct patterns of tumor response have required new norms for disease monitoring. A unique spectrum of toxicity is associated with use of immune checkpoint inhibitors which can be severe and refractory. Patients and clinicians must be informed regarding immune-related adverse events, yet in the published literature, there is substantial variability in reporting. As immune checkpoint inhibitors gain a prominent role in cancer treatment, standardization of adverse event reporting will be vital to ensure validity of evidence and to promote safe clinical practice.
