Radiotherapy and chemotherapy in cancer treatment during pregnancy: a literature review

Abstract

The coexistence of pregnancy and cancer is a challenging situation for the physician. Chemotherapy and radiotherapy are often necessary, depending on the type and stage of cancer at diagnosis. When applying such treatment, several key points concerning the health of the fetus must be carefully monitored. Meanwhile, if the appropriate treatment is delayed until postpartum, the mother's life may be at risk. Historically, the mother's health was placed above that of the fetus. This concept has changed, and harmonization of maternal and fetal health is now considered ideal. Numerous reports have shown the safe use of chemotherapy especially during the second and third trimesters of pregnancy. In 2004 our department treated seven cases of simultaneous cancer and pregnancy, leading us to review the use of chemotherapy and radiotherapy during pregnancy and the repercussions on neonatal outcome.
