July 2021—Liquid biopsy has entered a more confident era, with two FDA-approved next-generation sequencing assays for comprehensive tumor mutation profiling, evidence of its clinical utility, and broadened patient access.

February 2020—New microfluidic and nanotechnologies could take liquid biopsy to the next level as a tool to gauge cancer progression and treatment response.

February 2020—Microfluidic assays are being used to isolate circulating leukemia cells and manage minimal residual disease in some patients with acute myeloid leukemia and B-cell/T-cell acute lymphoblastic leukemia. “There is a lot of popularity in liquid biopsies, but there’s still a lot of work to do,” said Steven A. Soper, PhD, foundation distinguished professor of chemistry, mechanical engineering, and bioengineering at the University of Kansas. Dr. Soper, who also holds a teaching appointment at Ulsan National Institute of Science and Technology in Ulsan, South Korea, was a co-presenter with Sunitha Nagrath, PhD (see story, page 3), at the 2019 AMP annual meeting.

March 2019—The standard riff for talking about a promising new cancer test should be familiar to anyone within sneezing distance of a laboratory: There’s no one-size-fits-all assay. But if any test were to come close, it would be liquid biopsy. Are clinicians eager to use it? Check. Is it relatively simple to do (check) with fairly quick turnaround times (check)? Does it work for solid and hematological tumors? Check and check. Across multiple specimen types—serum, urine, vitreous fluid, cerebrospinal fluid, stool? Quite likely. Can it be used to characterize patients’ molecular profiles, monitor therapy, assess tumor evolution, identify resistance mechanisms, and detect early disease and minimal/measurable residual disease? Half a dozen checks. Even if liquid biopsy does fall short of a one-size-fits-all assay, it’s doing a reasonable impression of a Swiss Army knife (if not Sergeant Troy’s sword fantastic, for those of you who are Thomas Hardy fans).  

October 2017—Until recently, new treatments for stage 4 lung cancer have generally required weighing toxicity against hopes that patients’ average length of survival might be extended by a month or two. But “our expectations are increasing as therapies have improved,” says Geoff Oxnard, MD, thoracic oncologist at Dana-Farber Cancer Institute and assistant professor of medicine at Harvard Medical School. “Patients and doctors are increasingly expecting targeted therapies with dramatic effect and few side effects.”

March 2016—Lynette Sholl, MD, isn’t fully sold on that hottest of feverishly hot topics, liquid biopsy. “It’s kind of a sexy colloquialism, I suppose,” says Dr. Sholl, associate director, Center for Advanced Molecular Diagnostics, and associate pathologist, Brigham and Women’s Hospital, Boston. “Is there an official definition?”
