NCT ID: NCT05704010 Recruiting - Lynch Syndrome Clinical Trials

Videocapsule Endoscopy in Lynch Syndrome

Start date: November 1, 2018
Phase: N/A
Study type: Interventional

Background Lynch syndrome is caused by a pathogenic variant in one of the four Mismatch Repair genes (MMR): MLH1, MSH2/Epcam, MSH6, or PMS2. These pathogenic variants confer a higher risk of developing colorectal and other cancers, including small bowel cancer. The risk of developing a small bowel adenocarcinoma is about 100 times higher compared to individuals without Lynch syndrome, and the lifetime risk of small bowel cancer is estimated at 4,2%. The diagnosis of a small bowel cancer depends on videocapsule endoscopy (VCE). This device is swalled so that it can record images of the small bowel, which are then stored on a wearable device for about 8 hours. The capsule is then expelled in the feces while the images are transferred to a computer to be analysed. To date, there is conflicting evidence on the efficacy of small bowel cancer screening with VCE Rationale: this registry study will collect prospective data from patients with LS undergoing VCE Aim: evaluate the incidence of neoplastic and pre-neoplastic lesions in patients with LS during a VCE-based small bowel cancer screening study Design: this is a multicentric, observational study that analyzes data from diagnostic techniques already approved. Patients will not undergo diagnostic procedures beyond what would be recommended by clinical practice.

NCT ID: NCT05420064 Recruiting - BRCA1 Mutation Clinical Trials

An Intervention to Increase Genetic Testing in Families Who May Share a Gene Mutation Related to Cancer Risk

Start date: December 1, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate a cascade genetic testing intervention. Cascade testing is the process of offering genetic testing to people who are at risk of having inherited a possibly harmful gene change that has been found in their family. This process is repeated as more people within the family are found to have the gene change. The study will look at how often genetic testing occurs when healthcare providers have permission to reach out to family members to recommend genetic testing and to help those who are interested get tested. The study will look at whether this cascade testing intervention is practical and effective. The study would like to see how this approach of healthcare providers reaching out directly to family members compares with the usual approach of patients telling their family members about the recommendation to get genetic testing.

NCT ID: NCT04976439 Completed - Colorectal Cancer Clinical Trials

Patogenic Mutation in 5 Genes

Start date: May 1, 2021
Phase:
Study type: Observational

This is a pathogenic mutation profile of colorectal patients specifically in 5 genes, i.e. APC, TP53, PIK3CA, KRAS, and MLH1. Single nucleotide variants identified were synchronized with patients' characteristics.

NCT ID: NCT04009148 Recruiting - BRIP1 Gene Mutation Clinical Trials

Cascade Testing in Families With Newly Diagnosed Hereditary Breast and Ovarian Cancer Syndrome

Start date: March 1, 2019
Phase:
Study type: Observational

Identification of BRCA mutations in ovarian cancer patients may help guide cancer therapies, prognosis, post-operative screening, and other preventative treatments beyond the initial diagnosis. Likewise, genetic testing of ovarian cancer patients for these germline mutations provides invaluable information for families regarding cancer risk, genetic testing, and subsequently indication for risk-reducing surgery. Cascade testing provides a unique opportunity to identify carriers of a deleterious BRCA mutation which can allow for surgical and chemoprevention of prevention of ovarian cancer. There is currently no literature on the rates of referral for the family members.

NCT ID: NCT03631641 Active, not recruiting - Lynch Syndrome Clinical Trials

Nivolumab in Preventing Colon Adenomas in Participants With Lynch Syndrome and a History of Partial Colectomy

Start date: August 21, 2018
Phase: Phase 2
Study type: Interventional

This phase II trial studies how well nivolumab works in preventing colon adenomas in participants with Lynch syndrome and a history of surgery to remove part of the colon. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread.

NCT ID: NCT03005002 Completed - Clinical trials for Stage IV Colorectal Cancer

Durvalumab and Tremelimumab in Treating Patients With Microsatellite Stable Metastatic Colorectal Cancer to the Liver

Start date: June 28, 2017
Phase: Phase 1
Study type: Interventional

This pilot clinical trial studies the side effects and how well durvalumab and tremelimumab work in treating patients with microsatellite stable colorectal cancer that has spread to the liver. Monoclonal antibodies, such as durvalumab and tremelimumab, may interfere with the ability of tumor cells to grow and spread.

NCT ID: NCT02993068 Recruiting - HER2/Neu Negative Clinical Trials

Stand up to Cancer: MAGENTA (Making Genetic Testing Accessible)

Start date: April 18, 2017
Phase: N/A
Study type: Interventional

This randomized clinical trial studies how well online genetics educational video with or without pre- and/or post-telephone genetics counseling works in assessing cancer-risk distress in patients with triple negative breast cancer. Online genetic education and telephone genetic counseling may help the doctors learn the stress a person feels about their risk of cancer.
