Testing Proton Craniospinal Radiation Therapy Versus the Usual Radiation Therapy for Leptomeningeal Metastasis, RADIATE-LM 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.

Tumor Treating Fields for the Treatment of Leptomeningeal Metastases of the Spine in Patients With Breast or Lung Cancer

This clinical trial evaluates the safety and feasibility of tumor treating fields (TTF) in the treatment of spinal leptomeningeal disease in patients with breast or lung cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Patients wear the portable Novo TTF-200T device that produces electric fields to target areas on the body to stop the growth of tumor cells. The information from this study will help researchers develop a better treatment for leptomeningeal metastases in the future.

Hippocampal Avoidance in Craniospinal Irradiation for the Treatment of Leptomeningeal Metastases From Breast Cancer or Non-small Cell Lung Cancer

This phase II clinical trial studies how well craniospinal irradiation (CSI) with hippocampal avoidance, using proton therapy or volumetric modulated arc therapy (VMAT), works in treating patients with breast cancer or non-small cell lung cancer (NSCLC) that has spread from the original (primary) tumor to the cerebrospinal fluid (CSF) and meninges (thin layers of tissue that cover and protect the brain and spinal cord) (leptomeningeal metastases). Radiation therapy is an effective treatment in relieving localized symptoms caused by leptomeningeal metastases. However, the type of radiation therapy typically used does not prevent the spread of leptomeningeal disease. CSI (radiation therapy directed at the brain and spinal cord to kill tumor cells) may be able to target all of the areas of possible leptomeningeal tumor spread. CSI may however result in significant neurological side effects due to radiation damage to a part of the brain called the hippocampus. Hippocampal avoidance (HA) reduces the amount of radiation to the hippocampus. Proton or VMAT CSI with HA may be an effective treatment while reducing neurological side effects for patients with leptomeningeal metastases from breast cancer and NSCLC.

Photon Craniospinal Irradiation for the Treatment of Leptomeningeal Disease Secondary to Breast Cancer or Non-small Cell Lung Cancer

This phase II trial tests how well craniospinal irradiation (CSI) using photon volumetric modulated arc radiotherapy (VMAT) works in treating patients with breast cancer or non-small cell lung cancer (NSCLC) that has spread from the original (primary) tumor to the cerebrospinal fluid and meninges (thin layers of tissue that cover and protect the brain and spinal cord) (leptomeningeal disease). Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. CSI (radiation therapy directed at the brain and spinal cord to kill tumor cells) may be able to target all of the areas of possible leptomeningeal tumor spread. Photon-VMAT-CSI may be an effective treatment option for patients with leptomeningeal disease secondary to breast cancer or NSCLC.

Testing the Addition of an Anti-cancer Drug, Adavosertib, to Radiation Therapy for Patients With Incurable Esophageal and Gastroesophageal Junction Cancers

This phase I trial investigates the side effects and best dose of adavosertib and how well it works when given in combination with radiation therapy in treating patients with esophageal or gastroesophageal junction cancer for which no treatment is currently available (incurable). Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving adavosertib together with radiation therapy kill more tumor cells than radiation therapy alone in treating patients with esophageal and gastroesophageal junction cancer.

HER2-CAR T Cells in Treating Patients With Recurrent Brain or Leptomeningeal Metastases

This phase I trial studies the side effects and best dose of HER2-CAR T cells in treating patients with cancer that has spread to the brain or leptomeninges and has come back (recurrent). HER2-CAR T cells delivered into the ventricles of the brain may recognize and kill tumor cells.
