Abstract
Hodgkin lymphoma (HL) survivors are at risk of developing a range of therapy-related complications. The goal of this study is to investigate therapy-related late-effects in HL survivors. We performed a cross-sectional study on 208 HL survivors who were treated at the National Cancer Institute or at the Children Cancer Hospital Egypt with doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy. Age at diagnosis ranged from 2.5 to 17.5 with a median of 8.7 years. The cumulative incidence of cardiac toxicity at 5 and 9 years were 18.7%±2.7% and 43.3%±4.4%, respectively. Preexisting cardiac abnormalities, cumulative anthracycline dose, and end of treatment cardiac status are strong predictors of late cardiotoxicity. Hypertension was observed in ~31% of patients. Young age and obesity at the time of treatment are important risk factors for hypertension. Thyroid abnormalities developed with a 5-year cumulative incidence of 2%±1%, whereas at 9 years the cumulative incidence was 27.9%±4.5%. Thyroid dysfunction was observed in 21.2% and thyroid tumors in 1.6% of cases. Subclinical hypothyroidism was the most common thyroid abnormality. Cardiotoxicity, hypertension, and thyroid dysfunction are frequent late effects after doxorubicin, bleomycin, vinblastine, and dacarbazine regimen, especially if combined with radiation therapy.
