Performing non-invasive prenatal testing (NIPT) on a pregnant woman with a chromosomally abnormal neoplasm may incidentally lead to the diagnosis of cancer due to the coexistence of circulating tumor and placental DNA. Published information regarding NIPT’s accuracy for neoplasm screening is limited, and guidance for patient management is currently lacking. This challenges clinicians’ ability to counsel patients regarding the implications of these results, which often is the responsibility of a genetic counselor. Over three hundred board-eligible/certified genetic counselors were surveyed regarding their awareness, preferences, and attitudes towards NIPT’s ability to indicate maternal neoplasms. Despite 95% of this cohort being aware …

Non-invasive prenatal testing (NIPT) uses cell-free fetal DNA to assess for fetal aneuploidy during pregnancy. NIPT has higher detection rates and positive predictive values than previous methods; however, NIPT is not diagnostic. Studies suggest patients may underestimate the limitations of prenatal screening. Therefore, we conducted a prospective cross-sectional study of ninety-four women from genetic counseling clinics in Houston, Texas to assess patient understanding of the residual risk for aneuploidy after receiving a negative NIPT. The majority of participants (66%) understood the residual risk for Down syndrome following negative NIPT; however, 34% of participants indicated that negative NIPT completely eliminated the …
