Filter by:Background: - An important new area of brain tumor research is the development of tumor and brain stem cell lines. Successful growth of these cell lines requires obtaining large volumes of fresh tumor and brain tissue, which is best accomplished by harvesting whole brains from recently deceased patients. These cell lines will help researchers understand how these tumors develop and will also help identify new targets for treatment. Researchers are interested in conducting a pilot study of planned inpatient hospice care with timely brain tumor tissue harvest at the time of death. Objectives: - To provide high-quality end of life inpatient hospice care for patients with untreatable brain tumors. - To procure brain and tumor tissue shortly after time of death in order to derive viable tumor and neural stem cell lines for research purposes. Eligibility: - Individuals at least 18 years of age who have an untreatable primary brain or central nervous system tumor, are able to give informed consent (either their own or through a designated power of attorney), and have agreed to a Do Not Resuscitate order and Consent for Autopsy as part of the end-of-life care plan. - HIV-positive individuals or those suspected of having infectious cerebritis are not eligible because of the potential for contamination of brain tissue. Design: - Participants will be enrolled in inpatient hospice admission to the National Institutes of Health Clinical Center either from home or from an outside hospital once a study investigator estimates an expected survival of less than 2 weeks. - Participants will receive palliative care at the Clinical Center. Care will be tailored to each participant depending on the information provided in the individual's end-of-life care plan. - Supportive medications such as antiseizure medications and pain relievers will be administered as appropriate. - At the time of death, researchers will follow standard procedures for notifying next of kin and will collect brain tissue and tumor samples from the deceased. - Following tissue collection, the deceased will be released for autopsy and funeral procedures.
