CTCs

The company said adopters are ordering tests in areas of great interest, like CTC and blood biomarker monitoring, despite a lack of reimbursement.

The company's total revenue for the three months ended March 31 was $108.8 million compared to $92.6 million in the first quarter of 2018, exceeding analyst expectations.

A CTC and ctDNA analysis suggests that the number of alterations affecting the androgen receptor can offer survival insights for TP53 mutation-free advanced cancer cases.

The platform, from a University of Illinois at Chicago-led team, separates circulating tumor cells from other cell types using size-dependent inertial migration. 

Investigators are studying samples from a group of 100 patients to try to lock down patterns in circulating tumor DNA that can be used to validate monitoring methods for the clinic.

A new trial has compared the two most prominent tests, showing that both have clear predictive ability, but leaving several other questions unanswered so far.

Evidence is accumulating that analyzing cell-free DNA and/or samples from circulating tumor cells provides a good surrogate for bone marrow in these patients.
