Filter by: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.
It has been proved that concurrent radiotherapy (RT) and intrathecal methotrexate (MTX) for leptomeningeal metastases (LM) from solid tumors with adverse prognostic factors showed great effectiveness and safety. Cytarabine(Ara-C) is another agent which is commonly used for intrathecal chemotherapy. The purpose of the study is to observe the effectiveness and safety of concurrent RT and intrathecal chemotherapy for LM from solid tumors. In addition, the effectiveness of these two types of agents (MTX and Ara-C) in the concurrent chemo-radiotherapy will be compared in this study. This is a randomized controlled, parallel group, and phase II clinical trial. The object of this study is newly diagnosis patients with leptomeningeal metastases from solid tumors, who will accept the treatment of involved-field RT combined with concurrent intrathecal-MTX or intrathecal-Ara-C, respectively. Major endpoint is clinical response rate. Secondary endpoints are time to progression,severe adverse events and overall survival.
This study will prospectively enroll 36 evaluable subjects with breast cancer who are undergoing workup for clinical suspicion of leptomeningeal metastasis (LM). Neuroimaging consisting of MRI of the brain or total spine (or both, as clinically indicated) will be obtained in all patients. Patients will also undergo a lumbar puncture and standard CSF evaluation, which may consist of intracranial pressure measurement, CSF protein, glucose, white and red cell analysis, infectious cultures, as well as conventional cytopathologic analysis (cytocentrifuge). An additional CSF sample will be obtained for evaluation of CSF CTCs by OncoCEETM technology and cell-free DNA (recommended amount: 1 tube, 10 mL) at the time of lumbar puncture.
This research study is studying a combination of two drugs as a possible treatment for Leptomeningeal Metastases. The names of the study interventions involved in this study are: - Ipilimumab - Nivolumab
Leptomeningeal metastasis (LM) is one of the disastrous events when managing advanced Non-small cell lung cancer (NSCLC) due to a grave prognosis. Although intrathecal (IT) chemotherapy and brain and/or spinal axis irradiation show some effects for LM in advanced NSCLC, the prognosis is still poor with median survival less than 12-14 weeks. Epidermal growth factor (EGFR) tyrosine kinase inhibitors (TKIs) showed to be effective for LM in selected NSCLC patients in some retrospective research. Our single-center prospective research indicated that the incidence of EGFR sensitive mutations (EGFRm+) in NSCLC-LM patients was high and EGFR-TKIs showed a survival benefit for LM in EGFRm+ NSCLC patients. A multi-center prospective observational biomarker study will be started in 11 lung cancer center based on our single-center prospective research result. The aims of the study are to find predictive biomarkers for LM in advanced NSCLC, to establish EGFR-TKIs based comprehensive treatment for appropriate EGFRm+ LM cases, and to establish effective clinical assessment criteria for NSCLC-LM EGFR-TKIs treatment.
This is an expanded access study with ANG1005 treatment for two individual patients from Protocol ANG1005-CLN-03 with WHO Grade III Anaplastic Astrocytoma and WHO Grade III Anaplastic Oligodendroglioma and one individual patient from Protocol ANG1005-CLN-04 with Recurrent Brain Metastases and Leptomeningeal Carcinomatosis.
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 primary purpose of this study is to compare the positive rate between the cell-free DNA and cytological examination of cerebrospinal fluid in Advanced lung cancer with leptomeningeal metastases.
The main purpose of this study is to compare the effect of 10 mg and 15 mg methotrexate in the treatment of meningeal carcinomatosis.
The purpose of this study is to learn whether the DNA from cancer tumor cells can be found in the cerebral spinal fluid (CSF) that bathes the brain and spinal cord of patients before malignant the cancer cells themselves are able to be found in the CSF. The researchers doing this study hope this information can be used to develop a way to diagnose LM earlier .
