IDENTIFY Study: Natural History of Maternal Neoplasia
What this study is about
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.

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.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Women, age \>= 18 years.
- Pregnancy for which the following applies:
- Underwent blood noninvasive prenatal testing (NIPT) during pregnancy to screen for fetal chromosomal aneuploidies and had unusual results that either led to an interpretation of "non-reportable" or multiple aneuploidies inconsistent with a viable fetus.
- Normal-appearing fetus or fetuses on ultrasound examination and/or a normal fetal or neonatal karyotype. If a fetal anomaly is present but does not explain entirely the NIPT results, or there is a continuing concern for maternal cancer, the individual is still eligible for participation.
- Study enrollment may occur during pregnancy or up to two years postpartum.
- Ability to travel to NIH.
- Ability of subject to understand and the willingness to sign a written informed consent document.
Exclusion criteria
- -The following NIPT results will be excluded: --Abnormal results that have been associated previously with an increased risk for hematologic malignancy, including but not limited to, Trisomy 8, 20delq, 5delq.
Where
- Bethesda, Maryland

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
