The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The aim of this research is to find the undiscovered gene or genes responsible for hereditary colorectal cancer, and to understand how the gene(s) cause colorectal cancer. One of the best approaches used to find the answers to these questions is to study families where there are several family members affected with colorectal cancer.
Case probands and their relatives (affected and unaffected) will be recruited
(20 ml) of blood will be obtained on one occasion from each participant
Where tissues from affected family members have already been obtained (paraffin embedded tumour tissue in blocks) we will seek permission to access this material for DNA extraction. The duration of study will be approximately 48 months.

Outcomes
Primary outcome [1] 460 0
To identify molecular markers of potential value in understanding predisposition to CRC by their association with gene variants that increase the risk of CRC.
The study will be a family based analysis of SNP genotypes for cases and controls within families and between families. Transmission of disease associated SNPs will be assessed to determine within-family association and linkage and then to calculate across-family associations.
Timepoint [1] 460 0
2-3 blood samples per week over 36 months approx
Secondary outcome [1] 1001 0
If linkage is found then comparisons between families will be undertaken to determine whether the same SNP allele (or alleles) is associated in other families, thus providing a direct indicator of CRC risk. If this is the case, further testing in different ethnic groups may be necessary to extend the findings more broadly
