Active clinical trials for "Colorectal Neoplasms"

The study evaluates the protective effect of low-dose aspirin use on gastrointestinal cancers (colorectal, esophageal and gastric cancers) in long-term users, episodic users and non-users of aspirin in Taiwan.

In the UK, around 1 in 16 men and 1 in 20 women will develop bowel cancer at some point in their lives. Most bowel cancers happen when a type of growth in the bowel called an adenoma eventually becomes cancerous. Cutting out adenomas reduces the risk of developing bowel cancer. Certain people are more likely to have adenomas than others, for example people who are overweight. People who are overweight are also more likely to develop liver disease by laying too much fat down in the liver. Studies in Asia have shown that people with fatty liver disease are more likely to have adenomas and these are more commonly found in the part of the bowel (right colon) furthest from the bottom end. Information on the link between obesity, fatty liver disease and adenomas is very limited, particularly in the Western population. The investigators will assess the link between body weight, fatty liver and adenomas in the UK population. 1430 patients will be invited; some through the bowel cancer screening programme and some with symptoms such as low blood count, bleeding or changed bowel habit. These patients will already have been referred for a camera test looking into the bowel, called a colonoscopy. Information including height, weight and some health questions will be taken. Blood samples will be taken. The investigators will compare the number of patients with adenomas who have liver disease or who are overweight with those who don't. This information will be used to develop a scoring system to predict risk of adenomas. This will help the investigators to decide if undertaking colonoscopies in these patients will identify those at increased risk of bowel cancer.

Immune therapy represents a promising option for the treatment of an increasing number of malignancies. New immunotherapeutic strategies are currently under development and will be further studied starting from refractory settings of heavily pre-treated mCRC patients. On this basis, a specific immunological characterization of CRC metastasis will be relevant to direct future clinical and pharmacological research. As surgery is a therapeutic option in the treatment of mCRC, a percentage of mCRC patients undergo to resection of metastasis before or after medical treatment. These tumour samples could be useful to define the immune signature of colorectal metastatic disease. On the basis of the above reported considerations, an exploratory, prospective, observational study for the immunophenotypical characterization of colorectal cancer metastasis from pre-treated vs chemo-naive patients has been planned.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in American men and women with ≥130,000 new cases each year. Several dietary patterns have been associated with CRC risk but underlying mechanisms are not fully understood. Researchers thus propose to integrate dietary patterns and metabolomics data to comprehensively investigate biological pathways linking dietary patterns and CRC risk.

A non-interventional, prospective, open, multicenter study in Germany in patients with metastatic colorectal cancer who have been previously treated with, or are not considered candidates for, available therapies and with decision for treatment with trifluridin/tipiracil.

Regorafenib is currently the standard of care for refractory mCRC patients. Pivotal studies of regorafenib have proven the efficacy and safety, with a 28-day cycle (21 days on, 7 days off) and 160 mg dose given once daily. In the clinic, patients often have some complicated condition. This study aims to perform retrospective medical chart review of mCRC patients who received regorafenib treatment in two medical centers in Taiwan to examine treatment effectiveness in the routine clinical practice setting.

This is a two part observational study evaluating the feasibility of implementing an EHR-based model within a community oncology practice.

This is a single centre prospective biological translational research study involving the collection of tumour tissue, blood samples and clinical data from patients being treated with regorafenib for metastatic Colorectal Cancer (mCRC) at the Royal Marsden Hospital. Patients will be eligible for the study if they have a histological diagnosis of CRC, are refractory to standard available therapies with palliative intent for mCRC, have received prior treatment with at least one anti-VEGF antibody and chemotherapy drugs including fluorouracil (5FU) or capecitabine, oxaliplatin and irinotecan, and patients have RAS mutant tumours.

Participants will take part in a 12 week intervention, with at least one follow up at 24 +/- 2 weeks. Each participant will be provided with support, motivation and professional guidance about improving physical activity (PA) levels and will be given a commercially available PA tracker. The PA tracker will also include a smartphone or web-based application, where participants can upload their exercise performed each day, and keep up to date with their goals using their smartphone or by logging on to their computer. The aim of the study is to find out how useful and effective technology with support from a healthcare professional is in helping cancer survivors to become more physically active. This study will measure objective PA levels of the participants at the start of the study and at the end. The acceptability of using this intervention to promote PA in cancer survivors will also be investigated.

This non-interventional study will meta-analyze overall survival outcomes among the participants with metastatic colorectal cancer (mCRC) with available V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) status, who received firstline treatment with bevacizumab containing treatment regimen in routine clinical practice. The study leveraging secondary data from existing cohorts in the United Stats of America (USA), Germany, Australia, and Denmark.
