Primary Outcome Measures:
- Establish a Hereditary Colorectal Tumor Registry to facilitate development and implementation of epidemiological, clinical and cancer control research. [ Time Frame: 1-N/A ] [ Designated as safety issue: No ]
Other: Research Registry
If subjects agree to participate in the Hereditary Colorectal Tumor Registry their past, current and future medical record information will be placed into the research registry. This will permit research studies to be conducted on the medical record information contained within the registry.
In this registry, subjects will be asked to enroll based on their diagnosis of early onset colorectal cancer (age onset before 50 years old). Any subject who is less than 50 years of age will be asked to enroll if they have a history of colon polyps before age 50. MSI testing should be completed as standard of care before arriving in the Hereditary Colorectal Tumor Program clinic. However, if the subject has not had screening completed, he or she will have the MSI testing completed as part of their standard of care. Once MSI testing is complete and subjects meet the Bethesda / Revised Bethesda or Amsterdam Criteria (See Appendix 1), the clinical standard by which The American Gastroenterology Guidelines are accepted, the subjects will be referred to a genetic counselor. Once in contact with the genetic counselor they will be asked to participate in this registry. There will not be any retroactive or retrospective MSI/IHC testing as part of this registry.
If subjects agree to participate in the Hereditary Colorectal Tumor Registry their past, current and future medical record information will be placed into the research registry. This will permit research studies to be conducted on the medical record information contained within the registry. Subjects are being asked to allow us to contact them if one of our researchers determines, through review of medical record information contained in the research registry that subjects are eligible for participation in a future research study directed at the study of genetic colorectal cancer. Please note that if subjects qualify for any future research studies, they will be asked to sign a separate consent form that outlines in detail the nature of this research study, including its potential risks and benefits.
