There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Studying the genes expressed in samples of blood from young patients with cancer treated with ifosfamide may help doctors identify risk factors for kidney damage. PURPOSE: This clinical trial is looking at the CYP3A5 gene to see if having the gene may be a risk factor for kidney damage in young patients with cancer treated with ifosfamide.
Hypertrophic Cardiomyopathy is an inherited condition characterized by thickening (hypertrophy) of the heart muscle. Many patients who have this condition have a reduced ability to exercise because of breatlessness, which can in some cases be severe. This appears in most cases to be due to an impairment of the filling of the heart, especially on exercise this limits the amount of blood the heart is able to pump. Several factors may contribute to this slow filling of the heart, including (1) The heart contracts and relaxes in an incoordinate way (called 'dyssynchrony') which is inefficient, and (2) The filling of the main pumping chamber (the left ventricle) may be impeded by high pressure in the other ventricle(the right ventricle)- in other words the left ventricle is 'squashed' by the right ventricle. This is known as diastolic ventricular interaction. Although drugs can improve the filling of the heart and relieve symptoms, some patients remain very symptomatic despite these drugs. The mechanisms responsible for the filling abnormality in patients with Hypertrophic Cardiomyopathy are similar to those seen in the much more common condition known as Heart Failure. A special type of pacemaker technique called 'Biventricular Pacing' has been shown to markedly improve symtoms in patients with heart failure. This form of pacing has been shown to improve both 'dyssynchrony' ( incoordination) and 'ventricular interaction' (squashed left heart) in patients with Heart Failure. We propose that Biventricular pacing may similarly improve these abnormalities in patients with Hypertrophic Cardiomyopathy, resulting in an improvement of symptoms. The study will focus on patients with the condition who have severe symtoms despite being on optimal currently available drug therapy.
RATIONALE: Environmental exposure and genetic predisposition may affect the risk of developing cancer later in life. Learning about genetic markers and the long-term effects of environmental exposure may help the study of lung cancer in the future. PURPOSE: This research study is looking at risk factors and genetic markers in healthy participants and in patients with lung cancer.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, fluorouracil, leucovorin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving combination chemotherapy together with monoclonal antibodies 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. It is not yet known whether combination chemotherapy is more effective with or without cetuximab in treating liver metastases caused by colorectal cancer. PURPOSE: This randomized phase III trial is studying combination chemotherapy to compare how well it works when given with or without cetuximab before and after surgery in treating patients with resectable liver metastases caused by colorectal cancer.
To see if using medication called sulphonylureas can help improve symptoms which patients rely on to recognise low blood glucose levels ( hypoglycaemia) and also to see if they can reduce the slowing down in brain function which occurs at hypoglycaemia.
RATIONALE: Studying ways to diagnose fungal infections early may help doctors plan the best treatment. PURPOSE: This clinical trial is studying laboratory tests to see how well they find aspergillosis early in patients at high risk of fungal infection caused by treatment for hematologic cancer or other disease.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, carboplatin, and cisplatin, 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 combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving paclitaxel together with carboplatin followed by cisplatin and radiation therapy works in treating patients with stage IB, stage II, stage III, or stage IVA cervical cancer.
RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia(HCL) that has not responded to chemotherapy, surgery or radiation therapy. PURPOSE: Phase I dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have hairy cell leukemia (HCL) that has not responded to treatment.
The research is aimed at identifying new predisposition genes for endocrine tumours. Our focus initially is on pituitary adenomas including growth hormone-secreting tumors (somatotrophinomas) and prolactin secreting tumours (prolactinomas), but we wish to extend work to other pituitary tumour cases/families. The recruitment process will be as follows. 1. We will recruit patients from our own Endocrine outpatient clinics and inpatient wards. In addition we will ask colleagues in other Endocrinology Departments (or other specialties such as Clinical Genetics,Pathology, General Medicine ) to identify potentially suitable patients with endocrine & pituitary tumours from their records. We shall focus on patients with good evidence of inheritance of their condition: relatively early onset; or multiple lesions; or other affected family members. Conditions where the predisposing genes have been identified (principally MEN) will be excluded from study. Patients directly contacting us can also enter the study. 2. The Consultant looking after the patient will contact the patient to initially inform him/her of the study. 3. We will then contact the patient (generally by telephone) to discuss the study and what it would entail in terms of information and samples. 4. Subject to agreement in (3), patient will receive 'Information Sheet for patients with pituitary tumour' and 'Consent Form' and will have blood sampling in Consultant's clinic. 5. We will contact additional family members (if appropriate) after an initial approach by the family member already recruited to the study. The additional family members may have developed tumours similar to those of the proband, or may be unaffected individuals who provide useful information for gene identification purposes (for example, spouses may greatly aid the power of gene mapping by linkage. They will receive the "Information Sheet for family members". analysis). 8. Archival tissue will be obtained from HTA licensed tissue banks. This is an established bank whose licence is primarily for diagnosis but can be used for research. 9. We will undertake laboratory work, such as genetic linkage analysis, candidate gene mutation screening and studies of loss of heterozygosity in tumours, to identify the genes predisposing to the condition, such as the AIP gene. In addition we would like to screen other genes related to the chaperon AIP molecule, such as AhR, and other genes currently identified (PDE4A5, survivin and Tom20 protein) or may not been identified. Blood samples for DNA and RNA will coded with unique ID numbers. Pituitary and other endocrine tumour samples will be collected at surgery and kept in liquid nitrogen or -80 C. They will be coded with unique ID numbers. Candidate gene sequencing will be performed in the Barts and the London Medical School Genome Centre. RNA expression studies from blood or adenoma tissue samples will be performed by RT-PCR. Protein expression studies will be performed by Western blotting or immunohistochemistry. The first gene we wish to study causes familial acromegaly, a disease resulting from a pituitary adenoma secreting growth hormone. To establish if the candidate gene is also causing possibly sporadic (not familial) cases of the disease, samples (blood and tissue) will be collected from patients with sporadic disease and will be analysed as above.
RATIONALE: Identifying gene mutations and other risk factors in patients with melanoma and in families with a history of hereditary melanoma may help doctors identify persons at risk for melanoma and other types of cancer. It may also help the study of cancer in the future. PURPOSE: This clinical trial is studying gene mutations in patients with melanoma and in families with a history of hereditary melanoma.
