Study Examines Cases of Abnormal Prenatal Testing Results and Subsequent Diagnosis of Maternal Cancer
Researchers at Tufts Medical Center in Boston examined more than 125,000 noninvasive prenatal test results over the course of a two year period. Approximately 3,800 women had abnormal test results, and ten of those women were subsequently diagnosed with cancer. Medical records and additional genetic information were examined in eight of those women to look for patterns suggestive of underlying cancer.
Based on the results of the study, researchers estimate there is between a twenty and forty-four percent risk of maternal cancer if an abnormal number of chromosomes are detected. Further studies are needed to fully understand the clinical implications of these discordant results.
