Awareness towards an increasing concern during pregnancy: maternal and perinatal outcomes of women with cancer

Abstract

Increased incidence of cancer in women of childbearing age and improvements on treatment for preserving fertility have led to higher frequency of pregnancy during or after cancer treatment. This study aimed to describe maternal and perinatal outcomes associated with cancer and pregnancy and, as a secondary analysis, to compare outcomes of women with active disease and with remission before pregnancy. We performed a retrospective study of women followed up at a referral center owing to a history of cancer or cancer diagnosed during pregnancy. Data on sociodemographic information, obstetrical history, types of neoplasia, treatments offered, antenatal follow-up, and maternal and perinatal outcomes were retrieved from medical chart review. A descriptive analysis was performed and a comparison among women with active and nonactive disease was performed using Student t-test and chi-square test. A total of 66 women were included in a 5-year period. The most frequent types of cancer were breast (33%), hematologic (21%), brain (11%), cervical (9%), and ovarian (5%) cancers. There were 39 participants (59%) who had active disease and 26 who received oncological treatment during pregnancy, and 23 (34.8%) had a vaginal delivery. There were 4 women who needed intensive care unit admission postpartum. A total of 18 (29.5%) deliveries were at term, most newborns (59%) with adequate weight for gestational age and only 1 had Apgar score lower than 7 in the fifth minute of life. There was 1 stillbirth. The active invasive cancer during pregnancy group showed a higher rate of preterm birth and lower birthweight with significant statistical difference (P=.03 and P<.01, respectively). Breast cancer was the most frequent type of cancer in our cohort. Most deliveries were preterm, with adequate birthweight. Women with active cancer are more likely to have a preterm childbirth and newborns with lower birthweight.
