Liquid Biopsies (LBx) offer a promising alternative to tissue biopsies for cancer diagnosis and treatment, and promise to open a new era in cancer prevention for cancers like ovarian and pancreatic.
A new systematic review by Fagery et al., in Pharmacoeconomics, collects 24 studies in order to assess LBx health economics and modeling challenges in precision medicine.

Most studies (80%) conducted economic evaluations, with 75% demonstrating LB cost-effectiveness across diverse cancer types and stages. LBx were reported as beneficial for screening (2/3) and treatment selection (1/4). Budget impact varied, with many suggesting cost savings or modest impact. LBx could be cost-effective for lung cancer treatment selection and early detection of various cancers. However, "further research is needed," and the authors felt some publications under-rate modeling challenges, such as uncertainty.
