All clinical trials

Recently, a few small trials have shown promising results on value of fluoro-2-deoxy-D-glucose and positron emission tomography imaging in response assessment in Malignant Pleural Mesothelioma. These studies considered different parameters in Positron Emission Tomography (PET) analysis, mainly the standardized uptake value and volume-based parameters such as total glycolytic volume.

The purpose of this study is to investigate if there is any different follow-up results by angiography and IVUS between two different drug-eluting stents after implanted simultaneously in same individuals.

To compare the frequency of individual genetic abnormality between tumor cells and blood specimens.

Breast cancer is a common malignancy world-wide, and is the commonest female malignancy in Singapore, with rising trends in incidence over the last 2 decades. While there have been improvements in treatment, mortality from breast cancer remains significant. Development of biomarkers to predict treatment response and toxicity to anti-cancer agents can rationalize the choice of therapy for the individual patients to optimize treatment outcome and to reduce unnecessary toxicities. Development of novel therapies or novel approaches to therapy is also critical to improve the treatment armamentarium in breast cancer. These research strategies will have an significant impact on breast cancer treatment both in Singapore as well as globally.

Tinnitus is the occurrence of an auditory sensation without the presence of an acoustic stimulus. Approximately, 50 million people in the United States experience chronic tinnitus and 15 million of these people have bothersome tinnitus. Several studies have shown that people who are bothered by their tinnitus have difficulty in concentration and focus. Through imaging modalities we have deranged neural networks responsible for attention. Only 20 percent of patients diagnosed with tinnitus are severely bothered. We seek the following: Match a group of non-bothered tinnitus patients on age and hearing status to an existing cohort of bothered tinnitus patients. Assess the resting-state neural connectivity in patients with non-bothersome tinnitus. Findings from the comparison of functional connectivity magnetic resonance imaging (fcMRI) from subjects with bothersome tinnitus in our current rTMS clinical trial to normal age-matched controls without tinnitus demonstrates that subjects with bothersome tinnitus have dramatic alterations in cortical attention and control networks. Our hypothesis is that the fcMRI-defined changes in the attention and control networks reflect the impact of excessive auditory stimulation in patients with bothersome tinnitus and explains the difficulty with concentration, short-term memory, and other common problems. To fully test this hypothesis we need to obtain fcMRI of the attention network among subjects with tinnitus but without bother and compare the status of their neural networks with those of tinnitus subjects with bother and with normal controls. Compare the resting cortical networks in subjects with non-bothersome tinnitus to subjects with bothersome tinnitus and subjects without tinnitus Our null hypothesis is that there are no differences in the resting-state cortical networks, especially the attention and control networks, between tinnitus patients who do not experience bother, tinnitus patients who do experience bother, and subjects without tinnitus. Through fcMRI, we will examine correlations in blood oxygen level dependent (BOLD) signals in established auditory, attention, control, and other brain regions in the resting brain and compare these findings to already collected fcMRI scans of bothered tinnitus patients, and controls (patients without tinnitus).

To assess the incidence of occult hepatitis C virus in hemodialysed patients with mild impairment of liver enzymes

The purpose of the study is to evaluate the association between the number of circulating tumor cells and response to treatment in non small-cell lung cancer patients

The primary aim of this non interventional study is to assess the independent prognostic role on overall survival of primary tumour 18F-FDG uptake value (SUVmax) measured on 18fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in patients with non-metastatic non-small cell lung cancers treated with curative intent, taking into account the other conventional prognostic factors (performance status, age, sex, disease stage).

Arteriosclerosis is a common chronic disease with well known risk factors like diabetes mellitus, hypertension, dyslipidemia, adipositas and smoking, leading to severe complications like myocardial infarction, stroke or peripheral arterial occlusive disease. In addition to life-style factors there is also a genetic predisposition to develop complicated atherosclerosis. Objective: Improve individual risk prediction by clinical phenotyping and genotyping.
