Filter by:RATIONALE: Drugs used in chemotherapy, such as vincristine, irinotecan, ifosfamide, etoposide, doxorubicin, cyclophosphamide, and dactinomycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving high-dose combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase III trial is studying how well giving high-dose combination chemotherapy together with radiation therapy works in treating patients with newly diagnosed metastatic rhabdomyosarcoma or ectomesenchymoma.
RATIONALE: Vatalanib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well vatalanib works in treating patients with recurrent or progressive meningioma.
This phase III trial is studying observation to see how well a risk based treatment strategy works in patients with soft tissue sarcoma. In the study, patients are assigned to receive surgery +/- radiotherapy +/- chemotherapy depending on their risk of recurrence. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.
RATIONALE: Diagnostic procedures, such as positron emission tomography (PET) scan and computated tomography (CT) scan, may help doctors predict a patient's response to treatment and may help plan the best treatment. Drugs used in chemotherapy, such as doxorubicin and ifosfamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This clinical trial is studying how well PET scan combined with CT scan predicts response in patients undergoing chemotherapy and surgery for soft tissue sarcoma.
Retinoblastoma is a rare pediatric ocular tumor caused by germline and/or somatic mutations in the tumor suppressor gene RB1. Survivors of retinoblastoma, particularly those with the hereditary form of the disease (germline RB1 mutations) are highly susceptible to developing additional malignancies, which are a major cause of morbidity and mortality. Since 1984, REB has followed a cohort of 2136 (including 1,995 one-year) retinoblastoma survivors to investigate the contributions of treatment and genetic risk factors to second cancer etiology. The last systematic follow-up for second cancer incidence and cause-specific mortality was completed in 2009. As the cohort ages, we now propose to conduct another interview survey to collect information on newly diagnosed second cancers. Additionally, we propose to expand collection of germline DNA for additional molecular studies in survivors. Retinoblastoma survivors have now entered adult ages when epithelial tumors would be expected to occur with greater frequency. Given that the somatic mutations in the RB1 pathway have been identified in several epithelial tumors (bladder, brain, breast, esophagus, liver, lung, prostate) in addition to sarcomas, it is important to collect new information on these epithelial tumors, and to investigate whether the previously identified high risks of sarcomas and melanoma will persist as the cohort ages. Additionally, our understanding of genetic susceptibility to second cancers is limited. Given that this is the only cohort of long-term survivors of retinoblastoma being followed in the U.S., combined with the leadership role of REB in the study of second cancers, continued follow-up of this cohort will provide unique clinical and epidemiologic data on the long-term cumulative risk of second cancers in this distinctive cohort of childhood cancer survivors.
Background: Alveolar soft part sarcoma (ASPS) is a rare tumor. ASPS is resistant to chemotherapy and radiation. ASPS is characterized by slow growth. Currently no in vitro or in vivo models of ASPS exist for use in experimental therapeutic studies or biological investigations. Primary Objectives: Acquisition of blood and tissue from patients with ASPS. Acquisition of blood from healthy controls for comparison with blood from patients with ASPS. These control samples will be obtained from study NCI at Frederick Protocol OH99-C-N046. Eligibility: Subjects of any age with a diagnosis of primary or metastatic alveolar soft part sarcoma who are undergoing medically indicated surgery for their disease. Design: Patients with Alveolar Soft Part Sarcoma (ASPS) will be eligible for this study. Biopsy tissue will be obtained as an additional sample at the time of a medically indicated procedure. Blood sample may be collected at initial visit and follow-up visits. Specific risks will be described in a separate consent to be obtained at the time of the biopsy. Tumor samples and blood samples will be processed and/or stored for use in research efforts in the laboratory of Dr. David Vistica, National Cancer Institute, Frederick, MD. Additionally, blood samples will be obtained from healthy volunteers for comparison to patients with ASPS. These control samples will be obtained from the National Cancer Institute at Frederick Protocol OH99-C-N046.
A series of studies will be conducted in Sicily by a collaborative team from the U.S. National Cancer Institute and the University of Palermo to better understand the prevalence and risk factors for the newly discovered human herpes virus 8 (HHV8) and Kaposi s sarcoma (KS), which may be a consequence of HHV8 infection. There are four short-term projects: 1. To determine HHV8 seroprevalence in extant, unlinked sera from informative groups, including homosexual men, persons with sexually transmitted diseases, and in general population groups, particularly the elderly. In addition, HHV8 prevalence and other serological studies may be determined among other adults, particularly those who may be recruited for future studies and those likely to enhance understanding of HHV8 serology. 2. To identify a pediatric syndrome that might be associated with HHV8 infection, HHV8 seroprevalence will be determined in sera from hospitalized children with a wide range of clinical conditions. 3. To determine HHV8 seroprevalence in various regions of Italy and by HLA Class II groups that have been linked to increased (HLA-DR5) or decreased (HLA-DR3) risk of KS, using extant, unlinked sera and data from volunteer bone marrow donors. 4. To conduct a case control study that will identify risk factors for KS among persons who are infected with HHV8 and who manifest anti-HHV8 latent antibodies. The results of these projects will be summarized for publication in the medical and scientific literature and for the design and prioritization of related projects in the future.
This study will determine whether the results of a test called reverse transcriptase-polymerase chain reaction (RT-PCR) correlate with clinical outcomes in patients with Ewing sarcoma, and if they can be used to help identify patients at high risk for metastasis (spread of the cancer beyond the original site). This is a companion study to another NCI trial (AEWS0031), which is examining the effectiveness of an intensified chemotherapy regimen for patients with Ewing sarcoma. The primary purposes of AEWS0031 are to determine: 1) if chemotherapy given every 2 weeks can cure more patients with Ewing sarcoma and similar tumors than chemotherapy given every 3 weeks; and 2) if certain biological characteristics of these tumors can predict how well the chemotherapy will work. Many, but not all, patients with Ewing sarcoma that has not metastasized can be cured with standard radiation, surgery, and chemotherapy treatment. Most patients whose tumors have spread, however, are not cured with standard treatment. A goal of future therapy is to identify patients at highest risk for metastasis so that they can be given more intensive therapy, and, conversely, patients at lower risk of relapse can receive less toxic treatment. Patients enrolled in AEWS0031 are eligible for this companion study. No additional procedures re required; RT-PCR testing will be performed on blood and bone marrow samples collected for AEWS0031. ...
This study will try to identify risk factors for Kaposi s sarcoma, a rare skin cancer, and to understand the role of the KSHV virus in development of the disease. All native-born Italians 21 years of age or older residing in Sicily from July 1, 2002 through June 30, 2005 who have Kaposi s sarcoma not related to HIV infection may be eligible for this study. Healthy control subjects will also be enrolled. All participants will be interviewed about their childhood, jobs, habits, medical conditions, and treatments. They also will provide a blood sample and a saliva sample, obtained by swishing a mouthwash for 45 seconds and spitting it into a container. Blood will be tested for two viruses KSHV and HIV that are related to Kapsosi s sarcoma. The KSHV virus is newly discovered and not well understood. In general, a positive KSHV test probably means an infection with the virus has occurred in the past, but not necessarily that disease has developed. HIV is the virus that causes AIDS. People with AIDS have a high risk of Kapsosi s sarcoma. Although HIV and AIDS are very rare among older adults in Sicily, the presence of HIV must be ruled out in order to understand how KSHV is related to Kapsosi s sarcoma. The blood may also be used to measure immunity (the body s defense against infection and cancer) and for genetic studies to help discover why Kapsosi s sarcoma occurs.
RATIONALE: Diagnostic procedures, such as PET scan and CT scan, may help doctors determine the extent of cancer and predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying how well PET scan combined with CT scan evaluates treatment response in patients undergoing treatment for bone cancer or soft tissue sarcoma.
