7 Clinical Trials for Various Conditions
The researchers' laboratory is studying a rare class of highly recurrent hydatidiform moles. These are usually complete hydatidiform moles (CHM), but sometimes they are partial hydatidiform moles PHM). With sporadic moles, the difference between CHMs and PHMs is that with CHMS, there is not typically an embryo or fetus at the time of diagnosis but with a PHM there may be a fetus. Also, CHMs have 46 chromosomes in each cell. While this is the number of chromosomes that should be found, the problem is that all the chromosomes come from the father. Normally, half the chromosomes should come from the mother and half should come from the father. Unlike CHMs, PHMs have 69 chromosomes. This means that PHMs have three copies of each chromosome when they should only have two. The extra copy comes from the father. The researchers' study focuses on moles that are genetically different from these sporadic moles in that they have 23 chromosomes from the mother and 23 chromosomes from the father - just like a normally developing pregnancy. These are called biparental moles because the mutation that causes the mole comes from both parents. This mutation occurs in a gene called NLRP7. The researchers' team is working to understand how mutations in NLRP7 leads to CHMs and how these mutations may lead to other types of pregnancy loss. The researchers are also trying to discover other genetic and epigenetic factors that may lead to moles.
This phase II trial studies how well a second curettage (removal of the abnormal cancer cells in the uterus using a method of surgically removing the lining of the uterus) works in treating patients with gestational trophoblastic tumors that did not go away after a first curettage (persistent) and has not yet spread to other places in the body (non-metastatic). A second curettage may be effective in treating persistent gestational trophoblastic tumors and may decrease the likelihood that patients will need chemotherapy in the near future.
This randomized phase III trial studies how well methotrexate works compared to dactinomycin in treating patients with low-risk gestational trophoblastic neoplasia. Drugs used in chemotherapy, such as methotrexate and dactinomycin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether methotrexate is more effective than dactinomycin in treating gestational trophoblastic disease.
This phase II study is evaluating the activity of Pemetrexed in patients diagnosed with low risk Gestational Trophoblastic Tumor (GTT) that have failed prior treatment.
Randomized phase III trial to compare the effectiveness of methotrexate with that of dactinomycin in treating patients who have gestational trophoblastic neoplasia. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether methotrexate is more effective than dactinomycin in treating patients with gestational trophoblastic neoplasia.
The purpose of this study is to determine if inadvertent receipt of the BioThrax vaccine during pregnancy is independently associated with adverse maternal, pregnancy, or infant health outcomes.
RATIONALE: Amifostine may be effective in relieving numbness, tingling, and other symptoms of peripheral neuropathy. It is not yet known whether amifostine is effective in treating peripheral neuropathy in patients who have received chemotherapy for cancer. PURPOSE: This randomized phase III trial is studying amifostine to see how well it works compared to observation in relieving numbness, tingling, and other symptoms of peripheral neuropathy in patients who have received platinum-based chemotherapy (such as cisplatin or carboplatin) for cancer.
