Active clinical trials for "Colorectal Neoplasms"

This is a study to collect and analyze tissue specimens from metastatic colorectal cancer (mCRC) patients for the development of a molecularly profiled tissue repository for the primary purpose of maintaining a patient registry for future clinical trials based on the molecular profile of the tumors. The main purpose of testing these tissue specimens is to identify genetic alterations or biomarkers associated with colorectal cancer such that if new agent(s) become available, particularly those that target these genetic alterations/biomarkers, participants may be offered the opportunity to take part in a National Surgical Adjuvant Breast and Bowel Project (NSABP) treatment protocol.

This is a phase IV multicenter trial to evaluate real-world health outcomes and economic impact of panitumumab versus standard-of-care (SOC) in the treatment of patients with chemotherapy-refractory metastatic colorectal cancer (mCRC). The study will enable real-life health economics and outcome research (HEOR) to assess the impact of panitumumab in the Quebec population. The primary objective is to evaluate real-world health outcomes and economic impact of panitumumab in the treatment of patients with chemotherapy-refractory mCRC in comparison with SOC. The secondary objectives are to confirm survival data, to assess the quality of life of patients and to assess the health care resource utilization of patients. Patients with a mutated KRAS gene will be treated with standard-of-care (SOC) and patients with a non-mutated (wild type) KRAS gene will be treated with panitumumab. During the course of the study, data will be collected on quality of life and work productivity. Patients will be asked to fill a set of questionnaires at their recruitment in the study and at every 3 months after treatment initiation.

It has been shown that RFA induced systemic tumor antigen-specific T cell responses in human carcinoma. However, there are insufficient studies on the immune modulation of tumor microenviroment (TME) outside of the ablation zone. In order to study how RFA modifies TME in human cancer patients, investigators performed a retrospective study of a unique cohort of patients who suffered from synchronous CRCLM.

The goal of this research is to evaluate the relative advantage of remote counseling over usual care in community health practices without access to genetic services. We will evaluate ability of remote telemedicine, referred to going forward as TeleGenetic services (phone or videoconferencing), to increase uptake of genetic testing and identification of genetic carriers compared to usual care. Secondly, we will evaluate the advantages of videoconferencing over telephone for delivery of remote genetic services and the short-term and longitudinal outcomes of TeleGenetic services in socio-demographically diverse patients in community practices.

Combined with magnifying endoscopy,narrow-band imaging (NBI) contrasts microvascular architecture on lesion surface.The histology of early colorectal lesions could be predicted under NBI view.However,its capability for estimating invasion depth remains to be verified.The study is based on the hypothesis:NBI can predict histology and invasion depth,combined with the verification of microvessel count and MMP-7 expression.

This is a phase IV multicenter trial to evaluate real-world health outcomes, economic impact and resistance mechanisms of panitumumab in the treatment of patients with chemotherapy-refractory metastatic colorectal cancer (mCRC). This study will address two anticipated issues surrounding personalized medicine and treatment with panitumumab. First, it will enable to assess the economic impact of panitumumab in a real-life setting (HEOR study). Second, it will identify new blood-based mechanisms of resistance, which may lead to new avenues for combination therapy in metastatic colorectal cancer (Blood study). The primary objective is to collect information on quality of life and health care resource utilization by patients diagnosed with metastatic colorectal cancer. The secondary objectives are to confirm survival data, to assess the quality of life of patients and to assess the health care resource utilization of patients. The blood biomarker study objective is to determine blood-based biomarkers of response or resistance to panitumumab. Patients with a mutated KRAS gene will be treated with standard-of-care (SOC) and will participate to the HEOR study only. Patients with a non-mutated (wild type) KRAS gene will be treated with panitumumab and will participate to the HEOR study and to the blood biomarker study. During the course of the study, data will be collected on quality of life and work productivity. Patients will be asked to fill a set of questionnaires at their recruitment in the study and at every 3 months after treatment initiation. For patients participating to the blood study (patients with a wild type KRAS), blood samples will be collected before patients start their treatment, at every treatment and when they discontinue their treatment.

No ideal serum biomarker currently exists for the early diagnosis of colorectal cancer (CRC). Therefore, it is urgent that accurate and reliable serum biomarkers be identified.

The study aims to show non-inferiority in the clinical performance of the investigational assay, Epi proColon, to FIT using matched blood and stool specimens from screening-guideline eligible subjects.

The main objective of this study is to identify and characterize subpopulations of cells with invasive capacity in colorectal cancer from primary tumor, blood and metastatic samples.

The objective of this study is to confirm the sensitivity and specificity of a stool DNA test for detection of colorectal cancer and pre-cancer.
