The overall goal of this study is to find out what effects, good and/or bad, a low
dose and a high dose of lenalidomide have on children, adolescents and young
adults with recurrent (has come back after being treated), refractory (has not gone
away with previous treatment), or progressive (is not responding to previous
treatments) Juvenile Pilocytic Astrocytomas (JPA) and Optic Pathway Gliomas
This study is for patients with prostate cancer. The purpose of this study is to compare the effects of dose-escalated radiation therapy with or without hormone therapy on your prostate cancer.
There are 2 treatment groups in this study:
1) Patients who receive radiation therapy only
2) Patients who receive radiation therapy plus hormone therapy
Patients will receive 44 radiation treatments over approximately 2 months. If the patient chooses to receive the brachytherapy implant, he will receive 25 daily treatments plus the implant procedure over a timeframe of approximately 6 weeks. Hormone therapy, if given, will last 6 months. After patients are finished receiving therapy, the study doctor will ask them to visit the office for follow-up exams at 3, 6, 9, and 12 months after finishing radiation treatment, every 6 months for 4 years, and yearly thereafter.
the United States, it is standard treatment for patients with high-risk neuroblastoma (NBL) to receive the drugs carboplatin, etoposide and melphalan (CEM) as the preparative regimen in Consolidation therapy prior to Autologous Stem Cell Transplant (ASCT). BuMel Consolidation therapy has recently been studied in patients with high-risk NBL in some European countries. The findings from those studies indicate that the use of BuMel prior to ASCT may be linked to an increase in the survival rate for patients when compared to CEM. Those studies also indicate that the chance of the disease coming back (a relapse) may be lower among the patients who received BuMel Consolidation therapy. In North America the BuMel combination is considered experimental. In this study, researchers want to find out if a combination of busulfan and melphalan (BuMel) can be given as Consolidation therapy prior to ASCT for subjects with newly diagnosed high-risk NBL. The main goal of this study is to find out what effects, good and/or bad, a BuMel preparative regimen given before ASCT has on people with newly diagnosed high-risk NBL.
There is no current standard treatment for recurrent/refractory
medulloblastoma/PNET. The combination of the drugs temozolomide and
irinotecan has been used to treat adults and children with other types of cancer.
The combination has also been used in previous studies to treat a small number
of children with recurrent or refractory medulloblastoma/PNET as well as other
recurrent tumors, with encouraging results. This study uses the results of these
earlier studies, and looks at how well giving temozolomide and irinotecan daily
for 5 days every 28 days works when given to children and young adults with
recurrent or refractory medulloblastoma/PNET.
Ependymoma is a type of rare childhood cancer that occurs in the brain and spinal cord. Survival statistics are generally disappointing with a 5-year survival of 50-64%. The standard of care for ependymoma is maximal surgical resection followed by radiation therapy directed at the primary site of disease.
Radiation therapy is associated with immediate and long-term toxicities in children, especially young children. For this reason, it has been the practice of some doctors not to give radiation therapy to children with ependymoma when the tumor has been completely surgically removed. The investigators who designed this study have created strict measures to choose those who will not receive additional treatment after surgery and careful follow-up to minimize the risks to those who are assigned to observation only.
This study is for women or men with hormone responsive breast cancer that has already been removed by surgery and have completed any required chemotherapy or radiation. The purpose of this study is to see whether treatment with everolimus plus hormone treatment after chemotherapy will increase the time without cancer returning. The current standard treatment after chemotherapy is hormone treatment alone. Everolimus is a drug currently approved for the treatment of patients with advanced or metastatic kidney cancer. It is considered investigational for breast cancer patients. In this study subjects will get hormone treatment with either everolimus or with placebo (a pill with no medication). The combination of hormone-treatment and everolimus is experimental in patients with breast cancer.
It is expected that subjects will be enrolled in this study for approximately 54 weeks or until side effects become too great, or until cancer returns. After subjects are finished with study treatment, they will return to the clinic every six months for the first 2 years and then yearly for the next 10 years.
This study is for subjects with ovarian, fallopian tube or peritoneal primary cancer that has come back after original treatment. In this study, subjects will be able to choose whether or not to receive bevacizumab with paclitaxel and carboplatin or gemcitabine and carboplatin treatment. If subjects elect to receive bevacizumab, they will receive it every three weeks beginning with the second cycle of therapy and will continue to receive bevacizumab alone after therapy every three weeks as long as there is no evidence that their tumor is growing or that they are experiencing unacceptable side effects.
The primary purpose of this study is to determine if a second surgery to remove tumor followed by chemotherapy can increase the time that subjects remain disease free. If subjects' doctors feel that they are a good candidate for the second surgery they will be randomized to have surgery or not. A computer program will place subjects in one of the study groups. Neither subjects nor the doctor can choose the group they will be in. If subjects are randomized to receive the surgery it will be performed before chemotherapy is given. Chemotherapy will not be given until subjects recover from the surgery which could take up to six weeks.
Another purpose of this study is to test samples of subjects' blood, some of their tumor if left over from a previous surgery, and some of their tumor and normal tissue if left over from surgery performed as part of this study. The purpose of this research is to determine if this testing can be used in the future to determine which patients may respond to treatment, have side effects or have a good prognosis.
Subjects will receive chemotherapy treatment as long as there is evidence that they are benefiting from the therapy and are not experiencing unacceptable side effects up to a total of 8 treatments. If they choose to receive bevacizumab, subjects will receive this therapy in combination with chemotherapy. If subjects appear to be benefiting from treatment and have reached a maximum of 8 cycles of chemotherapy, they will receive bevacizumab as long as there is evidence that they are benefiting from the therapy and are not experiencing unacceptable side effects. Subjects will be followed by the study doctor for the rest of their lives. Subjects can withdraw from the study at any time.
This study is for subjects who have cancer of the colon, which has been surgically removed, but has spread to lymph nodes. This study is being done to evaluate the effects (good and bad) of different chemotherapy treatments. One of the common combinations of chemotherapy drugs used to treat this type of cancer includes 5-fluorouracil (also called 5-FU), leucovorin and oxaliplatin, and is also called “FOLFOX”. The Food and Drug Administration (FDA) has approved each of these drugs as treatment for colon cancer. FOLFOX is a standard treatment used to prevent colon cancer from coming back (recurrence).
In this study, researchers will evaluate the effects (good and bad) of an oral drug called celecoxib when given in combination with FOLFOX chemotherapy. Celecoxib is approved by the FDA to treat arthritis and some other painful conditions. The addition of celecoxib to FOLFOX chemotherapy is considered investigational. One of the purposes of this study is to determine if giving subjects celecoxib (by mouth) and chemotherapy decreases the risk of colon cancer recurrence.
This study will also look at whether receiving FOLFOX chemotherapy for 6 treatments (12 weeks) is as good as 12 treatments (24 weeks) in preventing recurrence of colon cancer. Currently, the standard of care is 12 treatments with FOLFOX. In this trial, researchers will explore whether 6 treatments are as effective as 12 treatments and whether side effects can be reduced with fewer treatments. It expected that subjects will be enrolled in this trial for up to 3 years.
This study uses a radiologic test called PET/CT scan to determine treatment after initial doses of a standard chemotherapy called "R-CHOP" (the drugs doxorubicin, cyclophosphamide, vincristine, prednisone and rituximab). Although all of the agents used in this study are FDA approved, the purpose of the study is to give more intensive treatment to subjects whose PET/CT scan shows that they are at a greater chance of still having active lymphoma, and to give less intensive treatment to patients whose PET/CT scan shows that they have a smaller chance of still having active lymphoma. In this way, we hope to improve the cure rate for all patients while decreasing the side effects of the treatment.
