New registry aims to unlock secrets of colorectal cancer in the Under-50 crowd
NCT ID NCT04489238
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study creates a database of information from people diagnosed with colorectal cancer before age 50. Researchers will compare this to data from older patients to find differences and potential causes. Participants complete a risk factor questionnaire and provide medical information over time. The goal is to improve understanding and future care for young onset colorectal cancer.

- What this could lead to
- If successful, this registry could help researchers identify risk factors and improve early detection and treatment for young onset colorectal cancer.
- What could go wrong
- This is an observational registry, not a treatment trial. It will not directly benefit participants and may not lead to immediate clinical changes.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Potential research subjects will be identified through the Center for Young Onset Gastrointestinal Cancer, a member of the patient's treatment team, the principal investigator, or research team at Memorial Sloan Kettering Cancer Center (MSKCC). All study participants will be recruited from patients under the care of consenting professionals. If the investigator is a member of the treatment team, s/he will screen their patient's medical records for suitable research study participants and discuss the study and their potential for enrolling in the research study. Potential subjects contacted by their treating physician will be referred to the investigator/research staff of the study.
