Non-Hodgkin's lymphoma during pregnancy.

A rare case of non-Hodgkin's lymphoma stage IE complicating pregnancy is presented. The diagnosis was made by biopsy at 28 weeks gestation and treated with 2635 rad of external radiotherapy with abdominal and pelvic shielding beginning at 30 weeks gestation. Following delivery, the patient received combination chemotherapy and is disease-free 6 years later. The baby, weighing 2015 g, was delivered by cesarean section at term. The effects of radiotherapy on a fetus are reviewed and the factors that were considered in the treatment of this patient are discussed. Radiotherapy with protective shielding can be an effective initial modality of treatment in this setting.
