Optimizing the Multidisciplinary Management of Nonmelanoma Skin Cancers: Update on Cutaneous Squamous Cell and Basal Cell Carcinomas — Video Program

Faculty

TARGET AUDIENCE
This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of skin cancer.

LEARNING OBJECTIVES

• Recall long-term outcomes with traditional treatment approaches for localized or locally advanced cutaneous squamous cell carcinoma (cSCC), and recognize clinical and histologic features that increase the risk of recurrence after primary therapy.
• Evaluate available research findings with immunotherapeutic agents as a component of neoadjuvant therapy for resectable cSCC in order to identify patients who may be appropriate candidates for this strategy.
• Appreciate recently published Phase III data supporting the use of adjuvant anti-PD-1 antibody therapy after surgery and radiation therapy for patients with high-risk cSCC, and consider the potential clinical utility and practical application of this approach.
• Use available clinical trial evidence to safely and effectively integrate immunotherapeutic approaches into the care of patients with advanced or metastatic cSCC.
• Formulate a long-term plan for the management of locally advanced or metastatic basal cell carcinoma (BCC), incorporating targeted and immunotherapeutic strategies.
• Recollect the rationale for and design of ongoing clinical trials evaluating novel agents and strategies for cSCC and BCC, and appropriately counsel patients about availability and participation.
