Study population: Individuals who are at increased risk for the development of cancer due to age over 50 years, a strong family history of cancer, known carrier of a pathogenic variant in a gene indicating an increased risk of cancer, for example a hereditary cancer syndrome, or due to exposure to environmental toxins, carcinogens, or mutagens, including tobacco. The individuals have to have the legal authority to provide consent, and therefore be 18 years of age or older.

Brief summary: Pathway Genomics Corporation (Pathway Genomics), a San Diego, California company, is involved in the development and validation of new molecular diagnostic assays for the analysis of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) found in the plasma-derived DNA (cell-free DNA or cfDNA) in order to identify specific variants (mutations) in cancer driver genes. The purpose of testing for mutations in ctDNA is to detect and monitor cancer. All cells shed DNA into the bloodstream. Finding cancer-associated mutations in the cfDNA may lead to early detection of cancer in an otherwise apparently healthy (i.e. asymptomatic) individual or may allow the healthcare provider to more effectively monitor and treat a known cancer patient. The analysis is performed using a polymerase chain reaction (PCR)-based methodology where oligonucleotides are designed to target specific mutations in designated genes of interest followed by next generation deep sequencing of the amplified targets. Evaluation of the performance of these assays for screening for cancer in asymptomatic subjects is essential for the clinical validation of the use of these assays. The specific aim of this protocol is to obtain relevant human blood samples from individual subjects at higher than average risk for the development of cancer due to age, heredity, or environmental or toxic exposures for use in the statistical analysis of this method as an adjunct screening test for the potential presence of cancer.

Detailed description: The objectives of this study are to obtain human blood samples from asymptomatic subjects who have never been diagnosed with cancer, but who may be at increased risk for cancer due to heredity, exposures, age, or family history to assess the validity of screening healthy but at risk patients for cancer via analysis of ctDNA.

Specifically, the blood specimens will be collected from individuals who have responded to a self-administered health questionnaire that screens for higher risk of contracting cancer. Each participant will be asked to provide a 30 ml blood sample to be drawn by a primary care provider (PCP) or licensed phlebotomist. The specimens collected during the study may also be used in the research and development of new or modified molecular genetics assays. The results of these studies will be used to further the understanding of the use of ctDNA for the detection and monitoring of cancer in humans.

The blood samples are collected in blood collection tubes (BCT) called Cell-Free DNA BCT® manufactured by Streck and intended for collection, stabilization and transportation of cell-free plasma DNA. This device also stabilizes and preserves cellular genomic DNA present in nucleated blood cells and circulating epithelial cells (tumor cells) found in whole blood. This product has not been cleared by the U.S. Food and Drug Administration for In Vitro Diagnostic use and is labeled by Streck for research use only. Under the Clinical Laboratory Improvement Amendments (CLIA) regulations, laboratories are authorized to validate and use, as part of a laboratory-developed test (LDT), devices that have not been cleared or approved by the FDA. Pathway Genomics validated the CancerInterceptTM Detect molecular analysis system with the Streck tubes, in accordance with CLIA.

Once the specimen has been collected and sent to Pathway by the physician or the phlebotomist who collects the samples, all other processing and testing are conducted by Pathway laboratory personnel. The analysis begins with the separation of the plasma from the rest of the blood sample. cfDNA will then be isolated from each sample. The quantity of cfDNA is measured and then the sample is amplified via PCR for next generation sequencing. The results of the sequencing will then be analyzed for the presence of one or more of the 96 mutations analyzed in this assay. The data are then reviewed and a report will be generated.
