Abstract
OBJECTIVES: This study aimed to characterize pregnancy outcomes and the incidence of induced abortion among pregnant people with a diagnosis of malignancy. STUDY DESIGN: We conducted a retrospective cohort study among privately insured people aged 12 to 55 years from the fourth quarter of 2015-2020 using US claims data from Merative MarketScan Research Databases. We included pregnancies from seven states with favorable policies for private insurance coverage of abortion. RESULTS: There were 1471 of 183,685 (0.8%) pregnancies with a cancer diagnosis. Among those receiving anticancer therapy, 21.6% (95% CI: 14.4-30.4%) underwent induced abortion compared with 10.9% (95% CI: 10.8-11.1%) of pregnant patients without a cancer diagnosis. CONCLUSIONS: Abortion restrictions may affect many pregnant women requiring cancer treatment in early pregnancy.
