Filter by:The purpose of the study is to learn more about neuro-oncology caregivers' quality of life and how friends and families help neuro-oncology cancer caregivers at different times during treatment.
This study assesses the number of CTCs before and 4-5 weeks after focal stereotactic radiotherapy, in single or fractionated dose, and correlate with the local and distant brain progression-free survival in patients with metastatic breast cancer.
Background: The field of nuclear medicine has changed a lot in the past decades. Technology has gotten better, so patients are exposed to less radiation. But now workers are doing procedures more often and using lead aprons less. So they may be exposed to more radiation. This may put them at higher risk for cancers and other health problems that are related to radiation. Researchers want to collect data from technologists to learn more about the risks and appropriate doses of radiation. Objective: To learn more about the risks and appropriate doses of radiation for nuclear medicine technologists. Eligibility: Adults who were first certified in nuclear medicine technology in the United States after 1980. They must be living in the United States. They must not be participants in the USRT study. Design: Participants will be recruited online. Participants will complete an online survey. It will take about a half hour. This will have questions about their work with nuclear medicine procedures. There will be questions about the kinds of procedures and how often they do them. Participants will give a short work history. This will include the names of current and past employers. Participants will allow researchers to get records of their film badge dose readings. These will come from dosimetry providers. Dosimetry data will not be shared with participants. Researchers can t ensure the how accurate or complete the data are.
This research study is studying an immunotherapy as a possible treatment for Glioblastoma.
This is a pilot study. The purpose of this study is to test if an imaging tracer, not approved by the FDA, called 11C-Choline (11C-CH) is useful for evaluating your type of cancer. This tracer is used to perform PET scans. The researchers want to see if the 11C-CH PET scan, using the study tracer 11C-CH, can improve upon the usual scans at diagnosing or monitoring your type of cancer. In patients with high-grade gliomas, changes on standard MRI of the brain may reflect true tumor growth or inflammatory changes in response to treatment, called pseudo-progression. It is important to distinguish true tumor growth from inflammation since inflammation indicates the tumor is responding to treatment. With standard MRI, it is difficult to determine if changes following treatment are due to tumor growth or inflammation early on. Researchers hope to learn if the investigational tracer, 11C-CH, will be able to distinguish true tumor growth from inflammation more accurately than standard MRI or 18F-FDG PET scans.
Cancer patients with brain metastases (BM) have poor prognosis. Current treatments produce limited efficacy. Recent advance in cancer immunotherapy has provided important new means to treat cancer patients at advanced stages. This study is designed to perform a clinical trial to treat advanced caner patients with brain metastases with personalized dendritic cell-based cellular vaccines. The patients will receive vaccines consisting of mRNA tumor antigen pulsed DCs. Immune response to the immunized tumor antigens will be monitored. Safety and efficacy will be observed in this study.
Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase II study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified oncolytic adenovirus, when delivered directly into the tumor followed by the administration of intravenous pembrolizumab (an immune checkpoint inhibitor) given every 3 weeks for up to 2 years or until disease progression.

Background: The Agricultural Health Study (AHS) studied farmers and their spouses in North Carolina and Iowa. It also included people who worked with pesticides in Iowa. They answered a questionnaire and gave data about their children born since 1975. Researchers want to link this data to public data like birth and death certificates. They want to study how early life exposures to farms are linked to cancer and other bad health outcomes. Objective: To study data to find links between early life farm exposure and negative health outcomes. Eligibility: There will be no human subjects. Design: Researchers will get public data in the two study states. This will come from things like: Birth certificates Driver s licenses Voter registration Death certificates Based on these plus the AHS data, they will create a study group. It will be called Early Life Exposure in Agriculture (ELEA). Researchers will link ELEA data to cancer data. This will identify prevalence of cancer. They will study parents answers on the AHS. The topics include farm practices and pesticide use. They will determine ELEA exposure to pesticides. Researchers will analyze the cancer and pesticide results and look for links.
The objective of this study is to evaluate the efficacy and safety of sugammadex in reversing profound neuromuscular block induced by rocuronium in infant patients
The purpose of this study is to evaluate patients with glioblastoma that is MGMT-unmethylated (the MGMT gene is not altered by a chemical change). Patients will receive Nivolumab every two weeks in addition to radiation therapy, and then every four weeks. They will be compared to patients receiving standard therapy with temozolomide in addition to radiation therapy.
