Summary: There is a general lack of data on effective cancer surveillance in most rare cancer predisposition disorders and this remains a challenge for patients with Bloom syndrome as well. A landmark study of patients with a different rare cancer predisposition disorder known as Li-Fraumeni Syndrome caused by germline TP53 variants showed that biochemical and imaging surveillance is feasible and associated with improved long-term survival. Standard cancer surveillance approaches though have limitations, including expense and invasiveness, leading to decreased compliance. Emerging technologies that enable longitudinal “liquid biopsies” have shown significant promise to detect cancer through peripheral blood sampling. The long-term goal of this project is to establish an international collaboration with sharing of biospecimens and data across borders in order to develop, validate, and test effectiveness of novel, minimally invasive cancer surveillance methods.
