Colorectal cancer, susceptibility to, on chromosome 15

This study is testing a blood test called GRAIL Galleri that looks for signs of many different cancers at once. It is being offered to 1000 people who have a high risk of cancer due to inherited genetic conditions. The goal is to see if the test can find cancers early, when they …

This study collects extra blood, urine, and tumor samples from children and adults with certain cancers to build a large tissue repository. Researchers will analyze these samples to learn more about the genetic and molecular makeup of these tumors. The goal is to support future s…

This study looks at genetic changes in families to figure out which ones truly increase cancer risk. Researchers will analyze DNA from 11,000 people, including those with certain gene variants and their relatives. The goal is to improve genetic counseling and help doctors decide …

This study collects blood, urine, saliva, and tissue samples from nearly 6,000 people who have or may have cancer, including rare inherited forms. The samples are stored and used for research to understand the genetic and molecular basis of cancer. No new treatment is being teste…

This study collects tissue samples, medical data, and family histories from over 1,100 people being screened for colorectal or endometrial cancer. Researchers hope to discover new genes and mechanisms that increase cancer risk, especially in hereditary cancer syndromes. The goal …

This study aims to discover new genes that may cause certain cancers to run in families. Researchers will collect blood samples and health information from 1,500 people in families where multiple members have had cancer, especially childhood cancers. The goal is to build a regist…

This study follows 56 young adults who have a genetic condition that raises their cancer risk. After they graduate from pediatric care at St. Jude, researchers track whether they find adult doctors and continue regular cancer screenings over 8 years. Participants fill out surveys…

This study tests whether web-based tools can help people with hereditary cancer syndromes share risk information with their relatives and encourage them to get genetic testing. Researchers will enroll 625 participants (patients and their relatives) and track how many use the tool…

This study from St. Jude Children's Research Hospital looks at how parents and children (ages 10-24) talk about the child's genetic risk for cancer. The goal is to understand what helps or hinders these conversations, so doctors can create better education programs. The study wil…

This study is looking at 2,000 people who have early warning signs of blood cancers or bone marrow failure. Researchers use a special genetic test (next generation sequencing) to find changes in cancer-related genes. The goal is to better understand who is at risk and to catch th…

This study compares two methods of offering cancer genetic testing to patients in community health centers. One method lets primary care doctors order tests directly, while the other uses a specialist model with extra support. Researchers will track how many patients get tested a…

This study compares a self-guided online genetic testing program to standard in-person counseling for people at risk of hereditary cancer. About 1,000 adults who meet national guidelines for genetic testing will participate. The goal is to see if the online option works just as w…

This study looks at a new way to help family members of cancer patients learn if they have inherited a higher risk for cancer. About 240 people with a known cancer gene change will be asked to share their test results with their close relatives, either on their own or with help f…

This study aims to discover new genes that increase the risk of developing cancer, especially in people with a strong family history or unusual cancer patterns. Researchers will analyze genetic data from 1,500 adults and children who have or may develop inherited cancer. The goal…

This study follows children under 21 who have a genetic condition that raises their risk of developing cancer, along with their relatives. Researchers will collect health information and samples over time to better understand how these cancers develop and how to catch them early.…
