Active clinical trials for "Neoplasms"

Prospective, observational, cohort study to evaluate the reliability of preoperative work-up of patients submitted to surgery for pancreatic cystic neoplasms, in a tertiary referral center. A comparison between the preoperative diagnostic suspicion and the final pathologic report will be done.

Marginal zone lymphoma is a rare of subtype of Non-Hodgkin Lymphoma. Because of its rarity, prospective clinical trial is difficult to conduct. Therefore we want to make prospective MZL patients' cohort for several observation study

Targeted next generation sequencing (NGS) provides a promising method for diagnostic purposes by enabling the simultaneous detection of multiple gene mutations. This study is to evaluate the feasibility and application value by using NGS into identifying genomic mutations in multiple or multifocal primary lung cancers in cell-tumor DNA (ctDNA) from surgical patients

Multi-centric, observational, prospective study, designed for pts with diagnosis of all-stages cholangiocarcinoma, including rare and crossing-over histological types, and excluding gallbladder cancer and ampullary carcinoma.

The investigators have developed an early detection solution for lung and breast cancer. A system which can distinguish between different medical odors based on biosensors. Our product is user-friendly noninvasive, nonradioactive and nontoxic to the patients. The technology enables a high level of sensitivity and provides users with a quick lab response and a simple yes or no answer. The aim of this study is to contribute and detect the patient at the earliest possible stage, in a noninvasive, nonradioactive and nontoxic way. Exhaled breath and urine samples are a promising approach towards future possible lung and breast cancer screening method.

In order to perform research smoothly, the process of information extraction is required for translating data in clinical text into available format for analysis and statistic. In medical research, the problem of missing data occurs frequently. It is important to develop the method with better imputation performance in the stability and accuracy. The purposes of this project are to provide the data integration and extraction methods for handling the structured and unstructured data sources in more efficient ways, to provide the validation scheme for facilitating the data reviewing of extracted results produced by information extraction modules, to increase the quality of clinical data by comparing the data from different data sources and correcting data errors and inconsistent, to handle the clinical data with the properties of time series and incompleteness, to increase accuracy of data analysis and increase quality of health care by improving the completeness and correctness of clinical data, to provide flexibility of methods in the platform. In the project, the disease topic is focused on the liver cancer patients' clinical data and we hope the methods in the projects can be extended to handle other diseases by replacing these knowledge models in the future.

There is a paucity of data on the aetiology of myeloproliferative neoplasms (MPNs). The investigators conducted a systematic review of the literature which identified several cohort and case-control studies that have investigated a wide range of potential medical, environmental and occupational risk factors. However, these studies have been limited by a wide variation in case definition and small sample sizes limiting the potential to detect modest risk differences between cases and controls. The research group propose an exploratory case-control study of 100 patients with classic MPNs and 200 controls to determine the optimal methods for roll out of this study to a multi-centred UK-based case-control study that will investigate the aetiology of MPN subtypes. The objectives of the study are to evaluate recruitment procedures, response rates, the development of a telephone administered questionnaire, compare occupational exposure assessment using OccIDEAS, a novel web based program, with a job-exposure matrix (FINJEM), evaluate the feasibility of collection of DNA from saliva compared to blood samples, identify potential aetiologic factors associated with MPNs and explore assessment of quality of life. The findings of this exploratory study will form the basis of a protocol for a large United Kingdom (UK)-wide case-control study of MPNs.

To demonstrate the use of WavSTAT4 system during colonoscopy in identifying diminutive colorectal lesions (e.g. hyperplastic polyps) that can be resected and discarded (or even left in-situ) without adverse clinical impact.

The purpose of this study is to provide a tool for physicians to compare outcome data related to the use of the HALO Ablation Systems. This study is a single-center patient registry which will contribute to a framework for treatment and follow-up of patients with Barrett's Esophagus.

The purposes of this study are to investigate the patterns of BCR-ABL mutations in CML and Ph positive ALL patients with imatinib resistance during the year of 2001-2009 in Asian institutes.
