The incidence of acute leukemia in pregnancy is low and even referral centers have limited experience. Although the short-term risks for children exposed in utero to cytotoxic agents are predictable, there is no information on long-term complications. We report here our experience in the treatment of seven cases of acute leukemia diagnosed during pregnancy, and a literature review of 51 cases published since 1975. Fifty-three patients received chemotherapy during their pregnancies. Forty-nine of the 58 cases resulted in the birth of 50 live infants. Twenty-eight infants were born prematurely, and four had low birth-weights for their gestational age. Thirty-three percent of the newborns exposed to chemotherapy in the last month of pregnancy were cytopenic at birth, but other perinatal complications were not increased. Only one child (present series) had obvious congenital malformations, and this same infant later developed a neuroblastoma arising in the adrenal gland and a papillary carcinoma of the thyroid. Follow-up data are not provided in most previously reported cases, but long-term follow-up of our cases from 1 to 17 years has shown normal growth and development and no further malignancies. A central registry is strongly advised in order to document the long-term complications arising in children exposed to chemotherapy in utero.
