Leptomeningeal Metastases: Novel Therapies, Future Directions and the Patient's Perspective

This panel session is the first ASTRO session dedicated to leptomeningeal disease in cancer. This is a case-based session with experts in neuroimaging, neuro-oncology, medical oncology, radiation oncology, as well as a patient speaker with LM disease who share their perspective. This comes on the heels of the landmark phase II randomized trial which showed improved central nervous system progression-free survival and overall survival with proton craniospinal irradiation (CSI) when compared to standard photon involved-field radiotherapy. We discuss several important aspects in the management of LM in this session. Using cases, we discuss the diagnosis and definition of LM disease as well as critical neuroimaging pearls (e.g., discerning LM disease from pachymeningeal disease). We go over cerebrospinal fluid (CSF) testing and intracranial pressure management. Furthermore, we discuss directed intrathecal therapies and systemic therapies for LM. We also discuss the most appropriate radiotherapeutic management based on patient selection, including photon involved-field radiotherapy, and proton and photon CSI. For all aspects, we deliver best practices, the latest scientific advances and how they could be incorporated into patient care. Most importantly, we also incorporate patient discussion and perspective in the treatment of LM.

    Full Panel 

This activity is available from March 5, 2024, through 11:59 p.m. Eastern time on March 4, 2026. 

This activity was originally recorded at the 2023 ASTRO Annual Meeting.

Target Audience

The activity is designed to meet the interests of medical oncologists, radiation oncologists, surgeons, physicists, nurses, diagnostic radiologists, residents, neuro-oncology specialists.  

Learning Objectives

Upon completion of this activity, participants should be able to:

  • Determine the current practice for patients with LM and the value of multidisciplinary management and opportunities for improvement.
  • Implement the diagnostic workup procedures for LM, including assessing for intracranial pressure and the appropriate management for it. 
  • Discuss treatment options with patients based on patient need and goals of care, including the most appropriate radiotherapeutic options and possible systemic and intrathecal treatment options as well as best supportive care.
