Active clinical trials for "Colorectal Neoplasms"

This study is a multi-centre retrospective observational research study which will be conducted in UK centres with specialised liver surgical services. The study will involve retrospective review of medical records of patients with metastatic colorectal cancer (mCRC) with metastases confined to the liver, defined locally as unresectable without downsizing therapy at first review by a Hepatobiliary Multi Disciplinary Team (HPB MDT). Erbitux is available for use in combination with chemotherapy as a downsizing treatment for patients with previously unresectable metastases. The study aims to examine liver resection rates achieved in normal clinical practice in order to inform National Health Service (NHS) clinical and policy decision making and to further understanding of how cetuximab is used in a standard clinical setting. This study intends to estimate the proportion of patients with unresectable liver metastases who undergo liver resection following downsizing treatment with chemotherapy plus cetuximab.

The PERFORM study is a pilot study investigating the feasibility and usefulness of performing a novel CT (Computed Tomography)scanning technique called Perfusion CT(CTP) as an addition to normal CT scanning in patients recruited to the FOXFIRE trial. All patients recruited to FOXFIRE at the Oxford Radcliffe Hospitals and University Hospitals of Leicester will be invited to take part. FOXFIRE is a national randomised controlled trial in which patients with unresectable liver tumours secondary to colorectal cancer will receive treatment with standard chemotherapy alone, or with chemotherapy in combination with an internal radiotherapy treatment which delivers radioactive particles(SIR-spheres) to the liver via its own blood supply (radioembolisation). In the FOXFIRE study a normal CT scan would usually be performed prior to the start of treatment and also three months after the commencement of treatment to assess the cancer's response to treatment, particularly whether the tumour has changed in size as a result of treatment. Perfusion CT gives the normal information on changes in tumour size but also assesses whether the blood flow to the cancer has changed, which may allow earlier identification of treatment success compared to normal CT scans. All patients consenting to participate in the PERFORM study will undergo four perfusion CT scans: one before the treatment starts, and one at the start of each of the second, third and fifth cycles of chemotherapy. The aim is to determine the feasibility of measuring tumour perfusion for data analysis using perfusion CT and to establish if the tumour perfusion pattern at baseline or shortly after the start of therapy can predict response to radioembolisation or chemotherapy. This research is funded by the National Institute for Health Research Biomedical Research Centre in Oxford and Oxfordshire Health Services Research Committee.

The purpose of this study is to determine if there is an association between hepatitis C infection and kidney cancer. All patients who are diagnosed with kidney cancer and who will either have a biopsy or surgery will be offered to be tested for hepatitis C. The control group will be colon cancer patients. Both groups would be of recent diagnosis (6 months).

We are doing this study to learn more about colon and rectal cancer survivors. We want to know if survivors want more information about life after cancer. Do cancer survivors want to know more about their own cancer? Do cancer survivors want to know about their treatment? Do cancer survivors want to know what health care they should get in the future? We want to know what information to give to cancer survivors when they finish treatment.

Colon and rectal cancer is the second most prevalent malignant disease in the western world, causing significant morbidity, mortality, and healthcare sources use. Treating colon and rectal cancer with curative intent generally includes resection of the primary tumor. Despite its crucial role, surgery by itself induce physiological changes resulting in significant immune depression and other physiological perturbations, which may in turn play a significant role in the initiation of new metastases and the progression of pre-existing dormant metastases. The aim of this study is to assess the use of perioperative medical intervention using a combination of a β-adrenergic blocker (Propranolol) and a COX2 inhibitor (Etodolac), in order to attenuate the surgically induced immunosuppression and other physiological perturbations, aiming to reduce the rate of tumor recurrence and distant metastatic disease.

This trial studies how well 4 dimensional (D) positron emission tomography/computed tomography (PET/CT) works in diagnosing participants with lung or colorectal cancer that has spread to the liver and lung. Diagnostic procedures, such as PET/CT, may help find and diagnose disease and find out how far the disease has spread. But the motions made by breathing can reduce the image quality of the scan. Adjusting the scanner to 4D may allow for more breathing motion may improve the quality of the PET/CT images.

The purpose of this study is to collect blood specimens and clinical data from screening guideline eligible individuals designated by their physician to receive a screening colonoscopy, and to evaluate the performance of a colorectal cancer-specific DNA methylation biomarker for detection of colorectal cancer in this cohort. Based on the outcome of the colonoscopy, polypectomy, biopsy and surgical tissue histopathology, the clinical utility of Septin 9 as colorectal cancer screening test will be evaluated.

Sox2 has been studied in several types of human solid tumors. The investigators found that Sox2 had higher expression level in colorectal cancer and metastatic tissues than normal tissues. So the investigators assumed that whether Sox2 plays an important role in the progression and migration of colon cancer.

The purpose of this registry is to collect information about patients in which a pouch has been created to improve in the future the quality of the surgery of the pouch.

The primary objective is to identify molecular features predicting response or resistance to cetuximab
