We evaluated the long-term effects of combined modality therapy (CMT) with adria-mycin, bleomycin, vinblastine, dacurbazine (ABVD) or mechlorethamine, vincristine, prednisone, procarbazine (MOPP)/ABVD plus adjuvant low-dose (<30 Gy) involved-field radiation therapy (LDRT) on cardiac and pulmonary functions in adult patients with Hodgkin 's disease (HD). Adjuvant LDRT (mean dose, 2340 cGy) to the mediastinum was administered to 24 patients after chemotherapy with MOPP/ ABVD (n = 10) and ABVD (n = 14). The mean doses of doxorubicin and bleomycin were 233 mg/m2 and 92 IU/m2, respectively. Cardiac and pulmonary function tests were performed in all patients and, when available, were compared with pretreatment studies. After a median follow-up of 6.3 years, none of the patients had cardiac or pulmonary symptoms. A 4.7% overall decrease in left ventricular ejection fraction (LVEF) was observed (p = 0.03), but only one patient had a mildly decreased LVEF (47%). Diastolic function, LVEF, and left ventricular volume remained within the normal range in the other 23 patients. Mild pulmonary function study abnormalities occurred in 8 of 24 patients, 6 of whom were cigarette smokers. There were no significant changes in total lung capacity and forced vital capacity (FVC) values, but there was a 3% overall decrease in FEV1/FVC ratio (p = 0.05). In adult patients with HD, adjuvant LDRT after chemotherapy with ABVD or MOPP/ABVD did not result in a significant incidence of permanent pulmonary or cardiac toxicity after more than 6.3 years of median follow-up. Further studies are warranted to fully evaluate the impact of such therapy on cardiopulmonary function.
