Trial Summary

What is the purpose of this trial?

This phase III trial compares proton craniospinal irradiation (pCSI) to involved-field radiation therapy (IFRT) for the treatment of breast or non-small cell lung cancer that has spread from where it first started to the cerebrospinal fluid filled space that surrounds the brain and spinal cord (leptomeningeal metastasis). Patients with leptomeningeal metastasis (LM) may develop multiple areas of nervous system (neurologic) impairment that can be life-threatening. Radiation therapy (RT) effectively relieves local symptoms due to LM. RT uses high energy radiography (x-rays), particles, or radioactive seeds to kill cancer cells and shrink tumors. IFRT is commonly used to treat symptoms of LM. IFRT is radiation treatment that uses x-rays to treat specific areas of LM and to relieve and/or prevent symptoms. pCSI uses protons that can be directed with more accuracy than x-rays which allows treatment of the entire central nervous system space containing the cerebrospinal fluid (CSF), brain, and spinal cord. The pCSI treatment could delay the worsening of LM. Giving pCSI may be better than IFRT in treating LM in patients with breast or non-small cell lung cancer.

Treatment Details

Interventions

  • Involved-Field Radiation Therapy
  • Proton Beam Craniospinal Irradiation
Trial OverviewThe RADIATE-LM Trial compares proton craniospinal irradiation (pCSI), which targets the entire central nervous system more accurately, against involved-field radiation therapy (IFRT), which treats specific areas of leptomeningeal metastasis using x-rays.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Arm 2 (pCSI)Experimental Treatment7 Interventions
Patients undergo pCSI radiation therapy delivered to the entire space containing the CSF, brain, and spinal cord 5 days a week for a total of 10 days of treatment in the absence of disease progression or unacceptable toxicity. Patients undergo CT or PET/CT during screening and MRI as well as possible LP throughout the study. Patients may optionally undergo research blood sample and CSF collection throughout the study.
Group II: Arm 1 (IFRT)Active Control7 Interventions
Patients undergo involved-field radiation therapy delivered to specific areas of LM that are causing and/or may cause symptoms 5 days a week for a total of 10 days of treatment in the absence of disease progression or unacceptable toxicity. Patients undergo CT or PET/CT during screening and MRI as well as LP throughout the study. Patients may optionally undergo research blood sample and CSF collection throughout the study.
