Active clinical trials for "Colorectal Neoplasms"

This is a single arm, phase 2, open-label, multicenter trial in patients with metastatic colorectal cancer (mCRC) and acquired resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs) and documented mutation of extra cellular domain EGFR (ECD-EGFR).

Objective: To compare the outcome of patients with colorectal cancer who treated with adjuvant therapy or Apatinib with adjuvant therapy postoperatively. Language: English.

A Retrospective Cohort Study to Evaluate a Multigene assay to assess the recurrence risk of colorectal cancer.

This study enrolling patients with metastatic colorectal cancer. Detecting CTC at different points in the treatment process. Descripting the molecular atlas of CTC in mCRC patients. Building and validating a response prediction system of mCTC patients.

The aim of the study is to obtain information on FLT used in a PET-scan as a marker for the proliferation of colorectal liver metastases, so that the risk of recurrence can be identified in a noninvasive way, concerning patients with resectable colorectal liver metastases. The hypothesis of this study is that a higher uptake of FLT in the liver metastases has a good correlation with the proliferation rate of the metastases. This rate is related to the risk of recurrence.

Clinical study participation percentages haven't always been fully representative of a given demographic. Participation in this observational clinical research is extremely valuable since it allows people with colorectal cancer to contribute their own experiences and unique viewpoints. These vital contributions have the potential to affect the development of novel therapies and support services dramatically. Trial's findings will be critical in furthering the understanding of colorectal cancer, ultimately leading to better patient outcomes.

This is an observational study in which data already collected from patients with metastatic colorectal cancer will be studied. Metastatic colorectal cancer (mCRC) is a cancer of the colon (large bowel) or the rectum (lowest part of the bowel just before the anus) that has spread to other parts of the body. The study drug, regorafenib, is already approved for cancer doctors to prescribe to patients with mCRC. It is an anti-cancer drug that blocks several proteins, called enzymes, which are involved in the growth of cancer. The participants in this study were treated with regorafenib as part of their regular care from their doctors. Some studies have shown that patients with mCRC who took regorafenib had improved survival outcomes, and some of them did well on the treatment for a long time. Cancer doctors have also reported from their routine practice that some patients with mCRC are able to respond to regorafenib for a longer period than others. However, there is limited knowledge about which people this is likely to happen for. To better understand the long-term response of regorafenib treatment, there is a need for a large-scale study in the real world. The main purpose of this study is to learn more about patients who showed a long-term response to regorafenib as a mono treatment for mCRC. To do this, researchers will collect the following information from the participants' health records: Duration of treatment with regorafenib Percentage of participants who received treatment with regorafenib for at least 5 months and 4 months. Characteristics, including age, sex, race, health condition, and signs and symptoms of mCRC, of participants who received treatment with regorafenib for at least 5 months and 4 months. The data will come from an electronic health records database called the Flatiron Health Data Repository for patients in the United States. The data will be from patients with mCRC who started treatment with regorafenib between July 2013 and December 2022. Researchers will consider the data of the participants collected until May 2023. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.

The investigators will detect circulating tumor DNA in blood of patients with lung metastases from colorectal cancer using NGS technology and intend to use it for predicting the outcome of local treatment (surgery or radiation) and recurrence of lung metastases.

This study is to determine how the Mainz Biomed Colorectal Cancer Screening Test works when used in people aged ≥45 years of age and at an average risk of developing colorectal cancer.

This clinical trial determines the feasibility of a multilevel approach to improve colorectal cancer screening within two rural regions of the Fred Hutchinson Cancer Research Center/University of Washington Consortium catchment area. The catchment area is the greater Puget Sound Region (13 counties). These rural counties have the highest overall rates of cancer incidence and mortality in the area; rural/small town residents in the catchment area had the lowest rates of meeting mammogram, Pap, and colorectal screening recommendations. This study involves observational data and questionnaire assessments to determine if an online version of the evidence-informed national colorectal cancer screening program, known as "Screen to Save (S2S)" and a fecal immunochemical test (FIT) kit distribution are acceptable and accessible to patients. FIT kits may help doctors find colorectal cancer sooner, when it may be easier to treat.
