Filter by:The purpose of this study is to find the safest and most effective dose for delivering proton beam to the space containing CSF, brain, and spinal cord, in treating leptomeningeal metastases. The researchers think that using proton beam radiation to treat the space containing CSF, brain, and spinal cord, instead of treating only the areas where the metastasized tumor cells are causing symptoms, would improve the treatment of this disease.
It has been proved that intrathecal chemotherapy is the main treatment strategy for leptomeningeal metastases. At present, the commonly used drugs for intrathecal chemotherapy include methotrexate, cytarabine, and liposomal cytarabine. In recent decades, no new effective drugs have been discovered for intrathecal chemotherapy. The recurrence of leptomeningeal metastases is inevitable even after aggressive treatment. There is no effective treatment for recurrent leptomeningeal metastases after comprehensive treatment which includes intrathecal methotrexate and/or cytarabine, central nervous system radiation therapy, systemic chemotherapy as well as tyrosine-kinase inhibitor drugs. The quality of life is extremely poor, and the patients always die in short time. Pemetrexed is a newer multitargeted antifolate which has shown activity in various tumors. It has higher effectiveness and safety, which has been used as the first-line treatment of non-small cell lung cancer. In animal studies, pemetrexed was demonstrated to suppress tumor growth completely in mice with two types of transplanted human colon xenografts resistant to methotrexate. Therefore, the purpose of the study is to evaluate the safety and feasibility of intrathecal pemetrexed in patients with recurrent leptomeningeal metastases from non-small cell lung cancer.
A study to assess the activity of tesevatinib in subjects with non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations who have disease progression with Brain Metastases (BM) or Leptomeningeal Metastases (LM) or who have either BM or LM at initial presentation (IP)
The purpose of this study is to evaluate the impact of Depocyte® IT combined with the systemic standard treatment in terms of clinical and/or radiological neuromeningeal progression free survival (SSPN)
This phase II trial studies how well giving liposomal cytarabine and high-dose methotrexate works in treating patients with breast cancer that has spread to the central nervous system. Drugs used in chemotherapy, such as liposomal cytarabine and methotrexate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving liposomal cytarabine with high-dose methotrexate may kill more tumor cells.
Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. This phase II trial is studying how well topotecan hydrochloride works in treating children with meningeal cancer that has not responded to previous treatment
