Long-term study of women whose prenatal DNA blood test suggested cancer in the mother

Background:

Pregnant women can get a DNA analysis of their blood. The test tells a woman and her doctor about the DNA of her unborn baby. But some women get test results that are abnormal or not reportable. Researchers want to learn more about the relationship between these test results and cancer.

Objective:

To better understand prenatal DNA test results and how they can predict cancer, if present, in pregnant women.

Eligibility:

Women 18 and older who got prenatal DNA test results that were abnormal or not reportable and suggested the abnormality was in the woman and not her baby.

Design:

Potential participants will be screened by phone or in person. They will talk about their medical history and send copies of their medical records.

Eligible participants will have a physical exam and medical history. They will give blood and stool samples. They may have a Pap smear. They will talk to a specialist about the test results they got when they were pregnant.

Participants will have magnetic resonance imaging (MRI). They will lie on a table that slides in and out of a metal tube, taking pictures.

Participants will complete a paper or electronic survey. It will assess their emotional well-being.

Participants will get a list of any possible diagnoses and treatment options.

Participants may be followed for up to 5 years. They may give blood samples and copies of their medical records. This can be done without traveling to the NIH. In some cases, people might come back to the NIH in one year to see if anything has changed.
