Abstract

Since 2017, the non-invasive prenatal test (NIPT) has been offered to all pregnant woman in the Netherlands in the context of the TRIDENT-2 study, which has been implemented as a trial within the Dutch national screening programme for Down's, Edwards' and Patau's syndrome. The NIPT examines cell-free DNA in maternal blood. A small proportion of this DNA is of placental origin, but a vast proportion originates from the expectant mother. Findings other than the aforementioned syndromes are considered incidental. Occasionally, maternal malignancy is suspected in asymptomatic women as a result of aberrant NIPT results. In this case series, we present three patients with suspected malignancy based on NIPT results. We recommend the implementation of clinical guidelines for when this situation arises.
