This is a prospective, multi-center, blinded feasibility study. The objective of this study is to test the feasibility of the detection of tumor DNA of a variety of tumors in peripheral blood using a novel process for the detection of circulating tumor DNA (ctDNA).

This prospective, multi-center, feasibility study represents a feasibility study to determine the potential of circulating tumor DNA exposure in peripheral blood using a novel process in a sample of patients with different types of malignant organ tumors and a control cohort without malignant disease. The study applies a new process to detect ctDNA and other molecular markers in peripheral blood using: a collection of de-identified blood specimen and clinical data from up to 10,000 participants from clinical sites across the United States and Europe. Data collected will include the following: Demographics, Tumor Characteristics, Information about Treatment, Specimen Assessment, Postoperative Assessment Clinical information, and Follow-up at intermittent future time points, for up to 15 years. The study test(s) to be used in this protocol is a multiplexed primer and probe design developed, that allows detecting a wider set of mutations at a higher sensitivity then conventional sequencing-based method. This novel process is currently being investigated at Quantgene Inc.
