Circulating Tumor DNA (Liquid Biopsy) and Circulating Tumor Cells

DESCRIPTION

Detection and quantification of circulating tumor DNA (ctDNA) also referred to as ‘liquid biopsy’, and circulating tumor cells (CTCs) in peripheral blood, has been proposed as a noninvasive alternative to tissue biopsy. The presence of CTCs (e.g., CellSearch® CTC) and ctDNA (e.g., Oncotype SEQ™, Guardant360®) has been documented in multiple tumor types, such as breast, prostate, lung, and colorectal carcinomas.

Both normal and tumor cells release DNA fragments into the blood. Studies have shown variable results for clinical sensitivity and it is not known to what degree genetic variances detected by ctDNA are representative of the primary tumor.

For individuals who have cancer or are at high risk of developing cancer who receive identification and quantification of CTCs, cutoff levels that should be used to signal a change in patient management are unknown.

POLICY

IMPORTANT REMINDERS

ADDITIONAL INFORMATION

The uncertainties concerning clinical validity and preclude conclusions about whether genetic variance analysis by ctDNA can replace analysis in tissue samples. The evidence is insufficient to determine the effects of the technology on health outcomes, therefore using liquid biopsy or the analysis of circulating tumor cells as a method to predict or manage any type of cancer remains investigational at this time.
