RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Celecoxib may be effective in preventing cervical cancer. PURPOSE: Randomized phase II trial to study the effectiveness of celecoxib in preventing cervical cancer in patients who have high-grade squamous intraepithelial lesions of the cervix.
This is a pilot study to examine the prevalence of metabolic risk factors (impaired insulin release and impaired insulin sensitivity) for type 2 diabetes mellitus in children and adults from a population that is at high risk for this disease. We hypothesize that at least one of these pre-diabetic traits will be evident in a large proportion of relatives of known type 2 diabetic children as compared to a control group of subjects without a family history of type 2 diabetes. By isolating these traits, it will be possible to determine the relative contributions of genes and environment to each trait and to identify those at risk for subsequent development of type 2 diabetes by virtue of having one trait. Ultimately, those individuals at risk, especially those with impaired insulin release, would hopefully benefit from intervention to prevent the weight gain that will 'unmask' their underlying pancreatic dysfunction and thus prevent or retard the development of type 2 diabetes.
Tenofovir disoproxil fumarate (also known as tenofovir DF or Viread) is used with other anti-HIV drugs to treat HIV infection. Taking tenofovir DF every day may also prevent HIV infection. This study will determine if taking a tenofovir DF tablet every day is safe and effective in preventing HIV infection. Participants in the study will be sex workers in Phnom Penh, Cambodia.
RATIONALE: Estrogen and progesterone can stimulate the growth of breast cancer cells. Hormone therapy using exemestane may fight breast cancer by reducing the production of estrogen and progesterone. Giving hormone therapy before surgery may shrink the tumor so it can be removed with breast-conserving surgery. Giving hormone therapy after surgery may kill any remaining tumor cells. PURPOSE: Phase II trial to study the effectiveness of neoadjuvant and adjuvant exemestane in treating postmenopausal women who have locally advancedestrogen and/or progesterone receptor-positive breast cancer.
RATIONALE: OTI-010 may be effective for graft-versus-host disease prophylaxis (prevention) in patients who are undergoing donor peripheral stem cell transplantation for hematologic malignancies (cancer of the blood or bone marrow). PURPOSE: This randomized phase II trial is studying how well OTI-010 works in preventing graft-versus-host disease in patients who are undergoing donor peripheral stem cell transplantation for hematologic cancer.
People recently infected with HIV who are treated with anti-HIV medications may develop strong immune system responses to HIV and may be able to control the virus without continuing to take these medications. The purpose of this study is to see if giving anti-HIV medications to people soon after they have been infected with HIV can help them control HIV. The study will also see if the immune system can control the amount of HIV virus in the blood (viral load) even after a person has stopped taking the medications. The study will evaluate three different schedules of stopping and starting anti-HIV medications to see which schedule is best able to boost a patient's immune system to control HIV viral load. Hypothesis: Combination therapy started in primary HIV infection, in conjunction with structured treatment interruptions, will result in greater control of viremia off treatment than induction therapy alone.
RATIONALE: Drugs used in chemotherapy, such as melphalan, arsenic trioxide, and ascorbic acid, work in different ways to stop cancer cells from dividing so they stop growing or die. Arsenic trioxide and ascorbic acid may also help melphalan kill more cancer cells by making them more sensitive to the drugs. PURPOSE: This phase II trial is studying how well giving melphalan together with arsenic trioxide and ascorbic acid works in treating patients with relapsed or refractory multiple myeloma.
Short-term therapy may reduce the amount of HIV in the blood of adults recently infected with HIV. The purpose of this study is to see whether it is better for people to take a short course of anti-HIV drugs when they are first infected or if it is better to wait until the HIV infection causes health problems before taking anti-HIV drugs.
The angiotensin receptor blocker (ARB) valsartan is a drug commonly used to treat high blood pressure. Valsartan may also help slow down the progression of kidney disease in HIV infected people. The purpose of this study is to compare valsartan and antiretroviral therapy (ART) to ART alone in slowing kidney disease progression in people with HIV.
RATIONALE: Vaccines made from DNA and a gene-modified virus may make the body build an immune response to kill tumor cells. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of liver cancer. PURPOSE: This phase I/II trial is studying the side effects and best dose of vaccine therapy and to see how well it works in treating patients with stage II, stage IIIA, stage IIIB, or stage IVA liver cancer.
