Mismatch Repair Gene Mutation

This is an multicenter study that will test the diagnostic accuracy of a blood test (i.e., a liquid biopsy) for the diagnosis of colorectal cancer (CRC), advanced adenomas (AAs), as well as Lynch-syndrome associated cancers. Additionally, a pre-planned analysis will evaluate the use of this liquid biopsy as a tool for molecular residual disease monitoring purposes.

The aim of the study is to determine if PET-CT imaging (using contrast recommended in clinical guidelines) is superior to combined bone scan and MRI/CT of the abdomen \& pelvis in detecting the increased incidence of metastasis (nodal/distant outside the pelvis) in men with prostatic carcinoma with mutations in any of the following germline DNA repair genes BRCA1, BRCA2, MSH2, MSH6, MLH1, PMS2, CHEK2, PALB2, ATM.
