Active clinical trials for "Colorectal Neoplasms"

This study will validate the real world results of polygene methylation detection in colorectal cancer in a large prospective community cohort. In this study, questionnaire survey and polygene methylation detection technology of colorectal cancer were used as preliminary screening methods, and colonoscopy was used as further validation examination method to screen colorectal cancer and precancerous lesions. The diagnosis and outcome of all lesions were based on colonoscopy and pathological examination.

The PREFACE Study is a prospective, longitudinal cohort study of reproductive health and clinical outcomes among individuals diagnosed with colorectal cancer between age 18 to 49 years.

This is a Registry that invites patients undergoing colorectal surgery for colorectal cancer. Epidemiological data is collected. The Registry includes tumor tissue and blood banks for analyzing different genetic mutations and disease-specific biomarkers.

The goal of this study is to create a registry of information about women who have or are at risk for Lynch syndrome, in order to study gynecologic cancer risks. This is an investigational study. Up to 1000 patients will take part in this study. All patients will be enrolled at MD Anderson.

Colorectal carcinoma (CRC) is the third most common malignancy worldwide. In Egypt, the relative frequency of CRC is about 9-12% with high male predominance 3:1. The high mortality rates associated with CRC is reflective of several factors including: the lack of apparent symptoms in the early stages and the absence of cancer prevention strategies in developing countries. Insulin-like growth factor II m-RNA-binding protein 3 (IMP3) is a member of the IMP family which plays a key role in the transfer and stabilization of mRNA, cell growth, and migration during embryogenesis. IMP3 has gained considerable interest as a cancer-associated protein. Previous studies strongly suggest that IMP3 may represent a valuable prognostic marker in human cancer. Its overexpression has been reported in a variety of human types of cancer, including lung cancer, colon cancer, pancreatic cancer, gastric cancer, liver cancer, and breast cancer

Constitution of a biobank of tissues, whole blood and plasma samples and stools to identify markers associated with treatment response, postoperative morbidity including neuro-cognitive and mood complications and prognosis of Inflammatory Bowel disease or colorectal cancer.

This is a comparative study. This study is to compare the diagnostic sensitivity between circulating tumor DNA methylation and carcinoembryonic antigen in detecting colorectal cancer. There are two steps in this study. Firstly, the diagnostic model is established based on tumor-specific plasma circulating tumor DNA methylation markers. Secondly, the sensitivity, specificity and accuracy of plasma circulating tumor DNA methylation are compared with that of carcinoembryonic antigen in detecting colorectal cancer.

This study wants to evaluate the use of MRI in the managemente of mCRC with liver only metastases.

This observational study aims to learn about the relationship between the nutritional status of patients with colorectal cancer and clinical outcome after colorectal surgery. The main question[s] it aims to answer are: which anthropometric, laboratory and specific parameters best define that patient is at nutritional risk will patients that are at nutritional risk stay longer in the hospital after surgery than those who are not at nutritional risk Patients will be preoperatively examined anthropometrically, radiologically and laboratoryally. Postoperatively, the course of their treatment will be monitored, as well as the monitoring of postoperative complications. A group of patients with and without malnutrition will be compared.

Fried Scale and its related scales were used to analyze the status and risk factors of preoperative frailty in elderly patients with colorectal cancer. R software was used to construct a risk prediction model for preoperative frailty in elderly patients with colorectal cancer, and its validity and stability were verified in clinical practice.
