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 mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

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 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.
