About
Objectives:
- To examine the variations in clinical features, survival outcomes, family history, and health behavior among proband patients who are known or suspected to have a hereditary colorectal cancer syndrome
- To compare the clinical features, survival outcomes, and health behavior of the proband vs. his/her family members who may or may not be affected by the hereditary colorectal cancer syndrome
- To explore for correlations between germline genetic variations in both the probands and family members with observed variations in the overall disease phenotype across probands and kindreds, within a given syndrome. Disease phenotype is defined to include: (1) clinicopathologic features including patient demographics and oncologic outcomes; (2) clinical manifestations of disease including the timing, spectrum and severity of CRC and extracolonic cancers. Genetic variations may include the specific codon mutated, the type of mutation and sequence alteration (e.g. nonsense, missense etc), chromosomal/gene copy number changes, and gene polymorphisms.
- To explore for correlations between germline genetic variations in both the probands and family members with observed variations in somatic CRC tumor biology, including tumor pathology and other tumor molecular markers

Participants:
Questionnaires:
If participant agrees to take part in this study, participant will fill out a some questionnaires about participant's work, family history, medical history, and health habits. If participant has already answered these questionnaires when participant was registered as a patient at MD Anderson, the study staff will give participant a copy and review participant's answers with participant for any updates or if participant has any questions. It should take about 20 minutes to complete the questionnaires.
Participant will also complete a health and lifestyle questionnaire, which contains 20 questions for men and 22 questions for women. This questionnaire should take about 10 minutes to complete.
Participant may be given the questionnaires electronically on REDcap (a secure, web-based application used to collect data for research studies that participant can access from participant's phone, tablet, or computer), over the phone (either with a member of the study staff asking questions or by using an electronic response system called IVR), at home through the mail, or in person by a member of the research staff at participant's MD Anderson visit. If mailed, a postage-paid return envelope will be provided for the return of the questionnaire.
Blood or Saliva Sample:
Blood (about 2-3 tablespoons) will be drawn. If possible, the blood will be drawn during an already scheduled blood draw to avoid additional needle sticks.
If participant is unwilling or unable to give a blood sample, participant may give a saliva sample instead. If participant is at MD Anderson, a saliva kit will be given to participant. If participant is not at MD Anderson, the kit will be mailed to participant with instructions for collecting the saliva sample and a prepaid envelope will be included to return the sample to the study staff.
The blood or saliva sample will be sent to the research laboratory of the study chairs at MD Anderson for testing.
Residual Tissue Collection:
If participant has tissue from procedures performed at MD Anderson, this tissue may be requested from participant's previous procedures for testing. If participant has had procedures done at another institution, participant may be asked to sign a waiver to allow the tissue from the outside institution to be sent to MD Anderson for testing.
Follow-Up Questionnaires:
Participant will also fill out a follow-up questionnaire at least 1 time in 5 years to update participant's medical, cancer, and family history. Each questionnaire will take approximately 20 minutes to complete.
Withdrawing from the Study:
Participant may withdraw from participation in this study at any time. If participant decides participant wants to stop taking part in this study, data collected about participant and data taken from the blood or saliva samples participant has provided up to the time participant withdraws will remain in study database and will be used for the purposes of the study.
Length of Study:
Participant's active participation on this study will be over after the blood, tissue, and/or saliva samples have been collected and participant has completed all of the questionnaires.
This is an investigational study.
Up to 2,000 patients and/or family members will take part in this study. All will be enrolled at MD Anderson.
Family Members:
Questionnaire:
Participant will complete a health questionnaire, which will collect information about participant's personal medical history, demographics (age, race, sex, and so on), and questions about participant's alcohol and tobacco use. This questionnaire should take about 20 minutes to complete.
Participant may be given the questionnaires electronically on REDcap (a secure, web-based application used to collect data for research studies that participant can access from participant's phone, tablet, or computer), over the phone (either with a member of the study staff asking questions or by using an electronic response system called IVR), at home through the mail, or in person by a member of the research staff at participant's family member's MD Anderson visit.
If mailed, a postage-paid return envelope will be provided for the return of the questionnaire.
Blood or Saliva Sample:
If participant agrees to take part in this study and participant is able to come to MD Anderson, blood (about 2-3 tablespoons) will be drawn.
If participant is unwilling or unable to give a blood sample, participant may give a saliva sample instead. If participant is at MD Anderson, a saliva kit will be given to participant. If participant is not at MD Anderson, the kit will be mailed to participant with instructions for collecting the saliva sample and a prepaid envelope will be included to return the sample to the study staff.
The blood or saliva sample will be sent to the research laboratory of the study chairs at MD Anderson for testing.
Outside Tissue Collection:
If participant has had a procedure done at a hospital, surgical center, or doctor's office outside of MD Anderson, participant may optionally be asked to sign a waiver to allow tissue stored at the outside hospital, surgical center, or doctor's office to be sent to researchers at MD Anderson.
Follow-Up Questionnaires:
Participant will also fill out a follow-up questionnaire at least 1 time in 5 years to update participant's medical, cancer, and family history. Each questionnaire will take approximately 20 minutes to complete.
Withdrawing from the Study:
Participant may withdraw from participation in this study at any time. If participant decides participant wants to stop taking part in this study, data collected about participant and data taken from the blood or saliva samples participant has provided up to the time participant withdraws will remain in study database and will be used for the purposes of the study.
Length of Study Participant's active participation on this study will be over after the blood, outside tissue and/or saliva samples have been collected and participant has completed all of the questionnaires.
This is an investigational study. Up to 2,000 patients and/or family members will take part in this study. All will be enrolled at MD Anderson.
