This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of desmoid tumors.

LEARNING OBJECTIVES

• Assess available clinical evidence documenting the efficacy and safety of various local and systemic management approaches for desmoid tumors, and determine the current indications for these strategies.
• Appreciate Phase III efficacy and safety findings with novel gamma secretase inhibitors for patients with progressing desmoid tumors in order to optimally incorporate available agents into management algorithms.
• Recognize the spectrum, frequency and severity of adverse events associated with novel gamma secretase inhibitors, and recall the supportive care strategies available to minimize and manage these toxicities.
