Filter by:This is an open-label phase II study of an investigational drug, sunitinib malate in patients with advanced malignant paraganglioma or phaeochromocytoma cancer. Paragangliomas (PGs) are tumours that arise from the para-sympathetic system in the head and neck and sympathetic system in the thorax and abdomen. Paragangliomas that secrete hormones (catecholamines) from the adrenal glands are called pheochromocytomas (PCs). In this study, patients whose disease has advanced or spread despite prior standard therapy, will receive sunitinib for 4-weeks followed by a 2-week rest period, for up to 12 months, in the absence of disease progression. Sunitinib is an investigational drug, which has been shown to shrink tumours in several tumour models. The study will evaluate the efficacy as well as the toxicity profile of sunitinib when used as an alternative treatment for patients with PG/PC tumours.
RATIONALE: Everolimus and vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving everolimus together with vatalanib may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of everolimus and vatalanib in treating patients with advanced solid tumors.
I-123-MIBG is used to image patients with neuroblastoma, pheochromocytoma and other neural crest tumors
The purpose of this study is to test the safety of a drug called Ultratrace iobenguane I 131 that has radioactivity, to measure how long it takes for the drug to be absorbed and passed out of the body, and to measure how much radioactivity is absorbed into different tissues of the body.
Hereditary paraganglioma -due to SDH (SDHD, SDHB, SDHC) germline mutations- causes paragangliomas and pheochromocytomas. Presymptomatic genetic testing should be offered to all first-degree relatives if an SDH mutation is detected in an index case with paraganglioma or pheochromocytoma. The main objective of our national clinical research project is to test different screening methods to detect presymptomatic tumors in order to establish guidelines for the work-up and the follow-up of SDH mutation carriers.
The study is designed to study the effectiveness of 123I-mIBG as a diagnostic imaging agent in evaluating patients with known or suspected neuroblastoma or phaeochromocytoma.
RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.
This study will evaluate the effectiveness of 131MIBG in treating malignant pheochromocytoma and whether sensitization medications improve the response to treatment. Pheochromocytoma is a rare type of tumor that usually occurs in the adrenal glands. The tumor cells release chemicals like adrenaline that can cause large increases in blood pressure and pulse rate, with serious health consequences. Tumor in the adrenal glands usually can be removed surgically, but if the pheochromocytoma is malignant-i.e., has spread to many sites in the body-or is located in places where surgery is difficult or impossible, no satisfactory treatment is available. 131MIBG is a combination of an adrenaline-like chemical and a radioactive form of iodine. The 131MIBG attaches to the tumor cells and the high concentration of radioactive iodine kills them. Previous studies using 131MIBG to treat pheochromocytoma had a 36% response rate in terms of complete or partial improvement. This study will examine whether adding other sensitization medications to the 131MIBG treatment regimen will enhance its effectiveness in reducing the size and number of tumors. Patients 18 years of age and older with malignant or inoperable pheochromocytoma may be eligible for this 18-month study. Candidates will be screened with various tests and procedures, which may include a medical history, physical examination, blood and urine tests, lung function studies, electrocardiogram, echocardiogram, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and bone scans and other scans using radioactive MIBG and octreotide. Participants will be randomly assigned to one of two treatment groups: 1) 131MIBG plus sensitization medications, or 2) 131MIBG alone. All patients will be hospitalized 3 to 5 days for each 131MIBG treatment. The drug will be infused through a vein (intravenously, or I.V.) over 10 to 30 minutes. Patients will receive up to 3 treatments, separated by at least 3 months. All patients will also take potassium to protect the thyroid gland from radioactive iodine generated by the 131MIBG. The potassium is taken twice a day for 30 days, beginning the day before the 131MIBG treatment. Patients in the sensitization group will receive the following additional drugs for sensitization: methylprednisolone, intravenously a few minutes before 131MIBG treatment; Roaccutan, by mouth (capsules) twice a day for 6 weeks before treatment; Demser, by mouth 3 times a week for 1 week before treatment, and Carbidopa, by mouth every 6 hours for 4 days before treatment. After each treatment, patients will have a clinical evaluation and periodic blood tests to check for adverse side effects of radiotherapy. Follow-up visits at NIH will be scheduled at 12 and 18 months after the first 131MIBG treatment for clinical, laboratory and imaging tests. Patients who had tumors in the lungs before treatment will have lung function tests 1, 3, and 6 months after each treatment. CT, MRI 131MIBG, and PET scanning will be done 1 week before each treatment. Patients who have tumors that have grown by more than 25% and none that have shrunk by more than 50% or who have developed one or more new tumors while on 131MIBG treatment will be taken off the study.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether surgery plus combination chemotherapy is more effective than surgery alone in treating patients with lung metastases from soft tissue sarcoma. PURPOSE: Randomized phase III trial to compare the effectiveness of surgery plus combination chemotherapy with that of surgery alone in treating patients who have soft tissue sarcoma that has spread to the lung.
RATIONALE: 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 giving chemotherapy after surgery is more effective than surgery alone in treating soft tissue sarcoma. PURPOSE: Randomized phase III trial to compare the effectiveness of surgery with or without chemotherapy in treating patients who have soft tissue sarcoma.
