Active clinical trials for "Colorectal Neoplasms"

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.

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.

This prospective database has two main objectives; to evaluate the complication rates, 30-day and 90-day mortality from different surgical strategies for unresectable, borderline resectable or initially unresectable liver metastasis from colorectal cancer. to establish baseline quality parameters for different surgical strategies for unresectable, borderline and initially unresectable colorectal liver metastasis (CRLM) patients.

The proposed study, IFACT - Incidental Findings in Advanced Cancer Therapy, will address this research gap by examining MSK patients' attitudes, preferences, and information needs regarding incidental findings arising from tumor genomic profiling.

The MET oncogene is known to sustain the Trousseau's syndrome in murine experimental models, featuring association of carcinogenesis with a blood procoagulant disorder. MET is frequently overexpressed in colorectal cancer, a tumor where venous thromboembolism (VTE) may occur in association with poor prognosis, but the biological and genetic factors that cause VTE are still obscure. The Investigators propose to study whether in patients harboring a surgically resectable colorectal cancer the MET oncogene is expressed and may be associated with a blood thrombophilic condition that favors the onset of VTE. These data would have two main implications: (i) for the first time, a direct genetic link between the MET oncogene and a procoagulant disorder would be demonstrated in humans; (ii) the procoagulant alterations would have diagnostic/prognostic significance for the identification of patients at risk for poor outcome, and implementation of appropriate therapeutic protocols.

Conflicting guideline recommendations for screening colonoscopy result due to scant data upon which to develop appropriate recommendations. No previous study has compared the prevalence of advanced adenomas or adenomas (any size) among 40-49 year old individuals with a first degree relative (FDR) with colorectal cancer (CRC) versus 40-49 year old average risk individuals with no family history of CRC. The purpose of this study is to determine the prevalence of colon adenomas in 40-49 year old individuals and identify risk factors associated with the presence of advanced adenomas. This data will provide evidence to determine appropriate colon cancer screening guidelines in 40-49 year old persons with a family history of colon polyps or colorectal cancer.

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.

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

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.
