Target Audience and Goal Statement

This activity is intended for oncologists (including pediatric oncologists), neurologists, neurosurgeons, neuropathologists, nurses, and other healthcare professionals (HCPs) involved in the care of patients with neuro-oncologic disorders.

The goal of this activity is for learners to be better able to recognize and care for patients with low-grade gliomas, glioblastoma (GBM), and neurofibromatosis type 1 (NF1)-associated tumors.

Upon completion of this activity, participants will:

  • Have increased knowledge regarding the
    • Defining characteristics of certain neuro-oncologic diseases
    • Clinical trial data evaluating therapies for patients with certain neuro-oncologic diseases
  • Have greater competence related to
    • Making an accurate diagnosis for patients with certain neuro-oncologic diseases
    • Individualizing care for patients with certain neuro-oncologic diseases
  • Demonstrate greater confidence in their ability to
    • Care for patients with certain neuro-oncologic diseases throughout their care journey
