The field is collecting evidence supporting genomics-guided care but experts are still awaiting prospective data and grappling with other challenges.

Presentations at the American Society of Clinical Oncology's virtual annual meeting included new findings relevant to both blood- and spinal fluid-based approaches.

ArcherDx will develop sequencing-based circulating tumor DNA assays for use in AstraZeneca's recently launched Phase III MERMAID-1 trial of durvalumab (Imfinzi).

Investigators are building upon an initial case study that allowed them to assess how well ctDNA captured a cancer's full genomic heterogeneity compared to tissue biopsies.

The company was able to increase its total revenue and test revenues despite accessioning fewer samples and fewer billable samples during the quarter.

The firm's precision oncology testing revenue more than doubled to $60.2 million, while its development services revenues contracted 7 percent.

Investigators reported on detection rates for cancers and precancers in a group of 350 individuals presenting for standard of care colonoscopy.

The company said the funds will support the continued development and commercialization of its genome-wide methylation assay for multi-cancer early detection.

Researchers argued that the field is ready for an expansion of adjuvant therapy trials informed by non-invasive, molecular measures of minimal residual disease.

At the AACR annual meeting, researchers shared detection rate data for multi-cancer screening tests from Grail and Thrive Earlier Detection.
