Dissecting the role of acetaldehyde in oral carcinogenesis
The goal of this study is to better understand how drinking alcohol may lead to oral cancers. Acetaldehyde, a chemical formed when the body breaks down alcohol, is believed to play an important role. This study will measure acetaldehyde and DNA damage levels in the mouth of participants after a low dose of alcohol. The levels will be compared between three groups, all having different degrees of risk for developing oral cancer, in order to identify DNA damage that might be crucial to cancer formation.
• 21 to 45 years of age: alcohol drinker of Eastern Asian descent who experiences flushing (reddening or warming of face) when drinking
• 21 years of age and older: alcohol drinker who have Fanconi Anemia
• 18 to 45 years of age: non-drinkers
• Tobacco or nicotine users
MT2012-11C: Second or Greater Allogeneic Hematopoietic Stem Cell Transplant Using Reduced Intensity Conditioning (RIC)
This is a treatment guideline for a second or greater allogeneic hematopoietic stem cell transplant (HSCT) using a reduced intensity conditioning (RIC) regimen. This regimen, consisting of busulfan, fludarabine, and low dose total body irradiation (TBI), is designed to promote engraftment in patients who failed to achieve an acceptable level of donor-derived engraftment following a previous allogeneic HSCT. While it will primarily be applied for the treatment of non-malignant diseases (NMD), on occasion it may be used to treat patients with malignant disorders as well.
Optimization of deep brain stimulation parameters in patients with medically refractory epilepsy
The purpose of this research is to better understand how deep brain stimulation settings can affect the electrical activity in the brain and the frequency of seizures. There are a number of different ways in which the deep brain stimulation electrodes can be programmed to stimulate the brain. This research study uses the implanted battery in the chest to record electrical activity from the brain at different stimulation settings. We then use this electrical activity to determine stimulation settings that are “personalized” to your brain.
Phase II Multi-Institutional Study of Low-Dose (2Gy x 2) Palliative Radiotherapy in the Treatment of Symptomatic Bone metastases from Multiple Myeloma
There is no consensus on the radiation dose required to relieve the pain from bone lesions from multiple myeloma. Usually, patients receive between 10 and 12 radiation treatments to achieve pain relief. But a shorter course of radiotherapy may be more effective. This study will evaluate whether pain relief can be achieved using only 1 or 2 radiation treatments, which will be delivered to a painful bone lesion. Your study doctor will decide whether you receive 1 or 2 treatments. The total amount of radiation you will receive will be the same whether it is done in one or two treatment sessions.
• diagnosis of multiple myeloma
• painful bone metastasis that has been confirmed by a xray
• may have had any number of prior chemotherapy/immunotherapy regimens
• at least able to walk and do all selfcare but may be unable to carry out any work activities; up and about more than 50% of waking hours
• see link to clinicaltrials.gov for additional requirements
• received prior radiation therapy or prior palliative surgery to the bone lesion that is causing pain
• pathologic fracture or impending fracture at the area of the bone lesion causing pain
• women who are pregnant
• additional criteria apply (study staff will review)
