Filter by:The Childhood Cancer Survivor Study (CCSS) will investigate the long-term effects of cancer and its associated therapies. A retrospective cohort study will be conducted through a multi-institutional collaboration, which will involve the identification and active follow-up of a cohort of approximately 50,000 survivors of cancer, diagnosed before 21 years of age, between 1970 and 1999 and 10,000 sibling controls. This project will study children and young adults exposed to specific therapeutic modalities, including radiation, chemotherapy, and/or surgery, who are at increased risk of late-occurring adverse health outcomes. A group of sibling controls will be identified and data collected for comparison purposes.
The purpose of this study is to determine, by means of DNA and protein analysis, the relationship between DNA and protein profiles and a number of endpoints, which are important for the patient such as overall survival and side effects.
Anastomotic leakage is a serious complication after LAR with high morbidity and mortality rates. Early diagnosis and treatment is mandatory. The primary aim of the present study is to investigate the clinical use of peritoneal microdialysis and whether is able to detect anastomotic leakage prior to clinical symptoms.
Warfarin is a commonly used anti-coagulant, but has a narrow therapeutic index and wide inter-individual and inter-ethnic variation in dose requirements. Several genetic and non-genetic factors have been identified that could influence warfarin dose requirements. However, current known predictive factors could only explain about 50-60% of warfarin dose variability. Inter-ethnic differences in genetic influences on warfarin dose requirements also exist. We hypothesize that genetic factors other than CYP2C9 and VKORC1 may influence warfarin dosing and serve to further optimize warfarin dosing.
To evaluate the efficiency of a microdevice for circulating tumor cells isolation and to correlate the circulating titre with response and progression.
The purpose of this study is to evaluate the immunogenicity and safety of an adjuvanted A(H1N1)v influenza vaccine in HIV-infected and immunosuppressed patients after one and two injections.
To investigate the protective effect of cervical cancer incidence and mortality by screening attending frequency or screening pattern, and to evaluate the possible risk of developing malignancies among women with cervical lesions, inflammation or infection.
Recent studies from both human and mice cancer models have demonstrated a crucial role for monocytes/macrophages in contributing to cancer progression and disease prognosis. However, since each cancer subtypes is associated with a unique tumor microenvironment in terms of its anatomical location, cytokine/chemokine profiles and stromal components, the functional contribution of tumor infiltrating cells such as the monocytes/macrophages can be equally diverse, depending on the type of cancer. Therefore to obtain a global understanding of the role of host immune cells in cancer progression, it is necessary to accurately characterize these cells in the context of the tumor microenvironment for several cancer subtypes rather than a single cancer. In view of this, this pilot proposal aims to carryout a systems approach in characterizing the functional phenotype of monocyte/macrophage lineage in 4 diverse human cancer types [e.g., Colorectal Cancer, Nasopharyngeal carcinoma, Hepatocellular (liver) cancer and Renal cell carcinoma (kidney cancer)] and the molecular basis of tumor-induced immunosuppression in each of these conditions. Besides providing a global view of the host innate immunity and its molecular basis in these human cancer, the outcome of this investigation will be crucial in defining the scopes of specific immunotherapy strategies to overcome tumor-induced immunosuppression and induce monocyte/macrophage-mediated antitumor response.
The objective of the study is to characterize the pharmacokinetic profile of granisetron patch after single administration to healthy subjects.
Aims of Research Proposal: 1. To build a DNA bank in association with a comprehensive database of treatment outcomes and toxicities of cancer patients. 2. To carry out genotyping of potential candidate genes in relation to specific anti-cancer agents and to correlate genotype with treatment outcomes and toxicities. The investigators hypothesize that genetic variations between different individuals and ethnic groups may account for inter-individual and inter-ethnic differences in treatment response and toxicities to anti-cancer therapy. The understanding of the contribution of these genetic variations may help to individualize therapy to optimize treatment outcomes and reduce toxicities. Patients will be recruited from the National University Hospital Cancer Centre. Any individual aged 18 or above who has been diagnosed with cancer is eligible. 20 ml of blood will be collected from each subject for DNA extraction and pharmacogenetics analysis. At the time of recruitment, demographic characteristics, cancer history, and past and present cancer treatment history of the study subject will be collected. The patients' progress will be followed up periodically (approximately every 6 months) through the medical records, and subsequent cancer treatments, progression of cancer, and survival outcome will be updated. Follow-up will occur until death. Important treatment information that will be collected include the drug regimen, drug doses, intent of treatment, aematologic and non-haematologic toxicities, and hospitalization episodes that may be related to treatment. Known functional single nucleotide polymorphisms (SNPs) of drug metabolizing enzymes, transporters and targets of different anti-cancer agents will be characterized. More comprehensive genotyping will be carried out in 'outliers' who experience exceptional toxicity or biological response to identify novel functional SNPs using high throughput sequencing techniques. Correlation will be made between genotype and treatment-related outcomes (tumor response, progression-free survival) and toxicities. For selected patients, lymphoblastoid transformation will be carried out to maintain an infinite supply of DNA.
