Prenatal cfDNA Sequencing and Incidental Detection of Maternal Cancer

Abstract

In this study, 48.6% of participants who received unusual or nonreportable clinical cfDNA-sequencing results had an occult cancer. Further study of DNA-sequencing patterns that are suggestive of occult cancer during prenatal screening is warranted.
