Successful Management of Primary Mediastinal Large B-cell Lymphoma during Pregnancy.

We experienced a pregnant woman with superior vena cava syndrome at 15 weeks of pregnancy who was diagnosed with primary mediastinal large B-cell lymphoma and given chemotherapy. In this case, the clinical courses of both the mother and infant were favorable without any serious complications because of close multidisciplinary cooperation. Based on a retrospective review of this case, the administration of CHOP-like regimens during the second and third trimesters appears relatively safe. Because pregnancy and continuation of pregnancy are rare in patients with hematopoietic malignancies, the accumulation of detailed information is important.
