Participants with new diagnosis of cancer (multiple tumor types) from which a blood sample and contemporaneous FFPE tumor tissue will be collected.
Participants with no known diagnosis or past history of cancer from which a blood sample will be collected.
- To collect and study clinically-annotated biospecimens, specifically peripheral blood and contemporary tumor tissue when available, to characterize cfNA profiles from deep sequencing and to estimate the population heterogeneity in two arms of the study. [ Time Frame: 30 months ]
- To develop and evaluate models for discriminating cancer versus non-cancer and tissue of origin. [ Time Frame: 30 months ]
- To evaluate concordance of variants identified in sequencing of tumor tissue and cfNA sequencing results in plasma from the same subject. [ Time Frame: 30 months ]
- To explore the relationship between genomic results and clinical outcomes based on collection of longitudinal information (at least annually for up to 5 years) from medical records for all consenting participants. [ Time Frame: Year 1, 2, 3, 4, 5 ]
- To enable assessment of the performance of an analytically validated clinical laboratory version of the NGS assay (under development) to detect circulating tumor DNA (ctDNA) in plasma. [ Time Frame: Year 1, 2, 3, 4, 5 ]
