Resistant starch may help prevent some cancers in people with Lynch syndrome

Questions To Ask Your Health Care Provider

• Is my family or personal medical history suggestive of Lynch syndrome?
• Should I have genetic testing for Lynch syndrome?
• Should I consult a dietician about my dietary fiber intake?
• Should I increase my dietary fiber intake? If so, how?
• How should I be screened for Lynch syndrome cancers?

Open Clinical Trials

The following screening and prevention studies are open to people with Lynch syndrome. 

Colorectal cancer

• NCT03831698: Omega 3 Fatty Acids in Colorectal Cancer (CRC) Prevention in Patients With Lynch Syndrome (COLYNE). This study is looking at the effects of omega-3 acid ethyl esters capsules (generic Lovaza) on molecular and intestinal microbiota changes in participants at high risk for colorectal cancer.
• NCT04379999: Atorvastatin ± Aspirin in Lynch Syndrome Syndrome. This study will investigate whether a common cholesterol lowering agent (atorvastatin) alone or combined with a nonsteroidal anti-inflammatory drug (aspirin) reduces the risk of colorectal cancer (CRC) in high-risk individuals with Lynch syndrome.

Gynecologic cancers

• NCT05257057: Frequency of Endometrial Cancer Precursors Associated With Lynch Syndrome. The purpose of this study is to examine endometrial hyperplasia specimens and compare the frequency of Lynch syndrome gene mutations between people with endometrial hyperplasia and those with endometrial cancer. 
• NCT00508573: Registry for Women Who Are At Risk Or May Have Lynch Syndrome. The goal of this study is to create a registry of information about women who have or are at risk for Lynch syndrome, to facilitate study of gynecologic cancer risks.
• Validating a Blood Test for Early Ovarian Cancer Detection in High-risk Women and Families: MicroRNA Detection Study (MiDE). The goal of MiDe is to develop a clinical diagnostic test to detect early-onset ovarian cancer, as currently, no reliable screening or early-detection tests are available. Participants can be expected to provide up to 4 tubes of blood every 6 months for up to 5 years. Samples can be collected through mobile phlebotomy all around the US.

Prostate cancer

• NCT03805919: Men at High Genetic Risk for Prostate Cancer. This is a prostate cancer screening study using MRI in high-risk men. This study is open to men with Lynch syndrome and other mutations.
• NCT05129605: Prostate Cancer Genetic Risk Evaluation and Screening Study (PROGRESS).  This study will look at how well prostate MRI works as a screening tool for men at high risk for prostate cancer. This study is open to men with an inherited mutation in ATM, BRCA1, BRCA2, BRIP1, CHEK2, EPCAM, HOXB13, MLH1, MSH2, MSH6, NBN, PALB2, PMS2, RAD51C, RAD51D, TP53 and other genes. 

Pancreatic cancer

• NCT02206360: Pancreatic Cancer Early Detection Program. This pancreatic cancer screening study uses esophageal ultrasound to screen for pancreatic cancer in high-risk people. The study is open to people who have a family history of pancreatic cancer and an MLH1 mutation or other mutation linked to increased cancer risk.
• NCT03568630: Blood Markers of Early Pancreas Cancer.  This pancreatic cancer study involves blood samples taken over time to look for biomarkers of pancreatic cancer in high-risk people. The study is open to people with an MLH1 mutation or other mutation linked to increased cancer risk.
• NCT03250078: A Pancreatic Cancer Screening Study in Hereditary High-Risk Individuals. The main goal of this study is to screen and detect pancreatic cancer and precursor lesions in individuals with a strong family history or genetic predisposition to pancreatic cancer. MRI and magnetic cholangiopancreatography (MRI/MRCP) will be utilized to screen for early-stage pancreatic lesions.

Other clinical trials for patients with endometrial cancer can be found here.
