Abstract
Pregnancy-associated diffuse large B-cell lymphoma (DLBCL) is a rare event. Experience regarding fetal effects of maternal treatment during pregnancy is limited. Cardiotoxicity is a known adverse effect of some antineoplastic agents especially of doxorubicin. We report a case of pregnancy-associated DLBCL, which was treated between gestational week 26 and 33 with three cycles of R-CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone combined with rituximab). At gestational age 34 2/7 she delivered a male infant who was admitted to neonatal care due to cardiomyopathy. In the absence of other explanations it was interpreted as a direct toxic effect of maternal chemotherapy. At age 6 months the boy's cardiac output had normalized. This case report is the first presenting congenital cardiomyopathy after maternal R-CHOP during pregnancy. Since especially anthracyclines are known to cause acute and chronic cardiotoxicity in treated patients, the most probable explanation for neonatal cardiomyopathy in this case is doxorubicin.
