Molecular Basis for Variations in Hereditary Colorectal Cancer Syndromes

M.D. Anderson Cancer Center · NCT02863172

Opens the official ClinicalTrials.gov record, with the study team’s contacts. Bored Studies doesn’t enroll anyone.

Key facts

Status re-checked against ClinicalTrials.gov within the last 12 hours.

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
