title: Accelerated increase in aortic diameter in patients treated for lymphoma.
abstract: Cytotoxic chemotherapeutic agents, particularly the anthracyclines, are known to be cardiotoxic, but toxic effects on the aorta have not previously been documented. In this study, diameters of ascending and descending thoracic aortae were measured by computerized tomography in 69 patients with lymphoma, before and after first-line treatment with one of 7 different regimes. Minor increases in aortic diameter over the study period due to the aging process were expected. These increases were greater than anticipated in both the ascending and the descending aortae after chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) and CVP (cyclophosphamide, vincristine, and prednisolone) regimes. Smaller changes, or changes which were not statistically significant, were noted after MVPP (mustine, vinblastine, procarbazine, and prednisolone), ChlVPP (chlorambucil, vinblastine, procarbazine, and prednisolone), ChlVP (chlorambucil, vincristine and prednisolone), mediastinal radiotherapy, and radiotherapy plus MVPP (MVPP/XRT). Cardiovascular damage associated with certain forms of cytotoxic therapy is not confined to the heart, but also affects the aorta.
