Late effects after treatment for Hodgkin lymphoma

Abstract

Although modern treatment strategies have made Hodgkin Lymphoma (HL) a highly curable disease, there is a life-long increased risk of morbidity and mortality due to treatment. Over time it has become increasingly evident that the historically used extensive treatment fields can potentially lead to numerous long-term adverse effects, often presenting clinically with a delay of more than 10-15 years. Epidemiological studies have shown an increased risks of second malignancies in HL survivors. HL survivors treated with mediastinal radiotherapy also have increased risk of late cardiac complications such as myocardial infarction, which might be due to radiation-induced coronary artery stenosis. All these adverse effects can severely impact health-related quality of life. This thesis investigates the long-term sequelae that HL survivors may encounter. The long-term risk of secondary skin cancers after radiotherapy in HL survivors was evaluated, and compared to the risks in the general Dutch population. The feasibility of screening for coronary artery disease by means of computed tomography coronary angiography (CTA) in HL survivors was investigated, and also satisfaction with information provision and the psychological burden of screening. Furthermore, the prevalence of fatigue in HL survivors compared with the general Dutch population, and associations with predisposing factors were assessed.
