Active clinical trials for "Colorectal Neoplasms"

The goal of this study is to create a data registry to capture clinical, pathologic, and molecular data/outcomes for patients with metastatic colorectal cancer who undergo live donor liver transplantation.

This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of cancers.

The aim of this project is to promote the breath volatile marker concept for colorectal cancer (CRC) screening by advancing developing the application of a novel hybrid analyzer for the purpose. The hybrid analyzer concept is expected to benefit of combining metal-oxide (MOX) and infrared spectrum (IR) sensor acquired data. The current study will be the first globally to address this concept in CRC detection. In addition, traditional methods, in particular, gas chromatography coupled to mass spectrometry (GC-MS) will be used to address the biological relevance of the VOCs emission from cancer tissue and will assist in further advances of the hybrid-sensing approach.

A prospective, observational study on clinical outcomes of surgical management of primary and metastatic colorectal cancer Prospective collection of tissues to explore potential biomarkers in blood and/or primary or secondary cancers and/or normal colon

Establishment of a tumor bank, consisting of blood samples of tumor patients and healthy people as controls. The blood samples will be collected systematically together with the corresponding clinical data. The biological samples, the clinical date together with prospective experimental date constitute the entity of the tumor bank.

Objectives: To examine the variations in clinical features, survival outcomes, family history, and health behavior among proband patients who are known or suspected to have a hereditary colorectal cancer syndrome To compare the clinical features, survival outcomes, and health behavior of the proband vs. his/her family members who may or may not be affected by the hereditary colorectal cancer syndrome To explore for correlations between germline genetic variations in both the probands and family members with observed variations in the overall disease phenotype across probands and kindreds, within a given syndrome. Disease phenotype is defined to include: (1) clinicopathologic features including patient demographics and oncologic outcomes; (2) clinical manifestations of disease including the timing, spectrum and severity of CRC and extracolonic cancers. Genetic variations may include the specific codon mutated, the type of mutation and sequence alteration (e.g. nonsense, missense etc), chromosomal/gene copy number changes, and gene polymorphisms. To explore for correlations between germline genetic variations in both the probands and family members with observed variations in somatic CRC tumor biology, including tumor pathology and other tumor molecular markers

The primary objective of this study is to collect de-identified, clinically-characterized stool and whole blood specimens for use in developing and evaluating the performance of new biomarker assays for the detection of colorectal cancer (CRC).

Investigators propose a retrospective cohort study to examine the impact of radiation therapy on the global pelvic floor function of women who have completed the immediate surveillance period for colorectal cancer

Patients suspected of adenomatous polyposis were included. The criteria used were more than 10 polyps observed under colonoscopy, and pathological confirmation of adenoma. Clinical data and pedigree information were collected. The variants of 139 genes associated with different hereditary cancers and polyposis were screened by NGS, which was performed by Genetron Health on the HiSeqX-ten sequencing platform.

This study will be a prospective analysis conducted by Geneoscopy Inc. to evaluate the Colosense test, which is a multi-target stool RNA test for colorectal screening.
