Cardiac injury as late toxicity of mediastinal radiation therapy for Hodgkin's disease patients.

چکیده
BACKGROUND During the last 20 years Hodgkin's disease (HD) has become one of the most curable neoplasms; in fact, more than 75-80% of patients are expected to achieve long-term relapse-free survival with appropriate therapy. However, overall survival has been affected by intercurrent or treatment-induced diseases such as the increased risk of cardiac toxicity in patients who received mediastinal irradiation. METHODS The incidence of cardiac abnormalities after mediastinal radiotherapy was assessed in 102 consecutive HD patients who underwent this treatment from January 1970 to December 1980. Basal investigation procedures included electrocardiogram and echocardiography; myocardial perfusion scintigraphy with 201-thallium and coronary arteriography were performed in selected patients. RESULTS Eleven patients (10.8%) presented cardiac abnormalities, which were asymptomatic in three cases. Eight cases of myocardial ischemia and 3 of constrictive pericarditis were observed. The incidence of late cardiotoxic effects was related to total mediastinal dose and to the irradiation technique. CONCLUSIONS The increasing duration of follow-up shows that as mediastinal irradiation increases so does the risk of late cardiotoxic side effects. For this reason, a proper treatment strategy should reduce these risk factors through new combined modality protocols and routine evaluation of cardiologic follow-up.

متن کاملComplications of thoracic radiotherapy.
The issue of toxicity is a primary concern for chest irradiation, because it is a dose-limiting toxicity and because in some circumstances it can alleviate the survival benefit of radiation therapy. Potential acute and delayed side effects can compromise the patients' prognosis and generate significant morbidity. Here we review on chest complications of radiation therapy, with focus on cardiac ...
متن کاملPrecocious myocardial infarction after radiation treatment for Hodgkin's disease.
A 26-year-old man received extensive cardiac radiation in the course of treatment of mediastinal Hodgkin's disease, and six years later, he experienced an acute myocardial infarction. Angiographic studies demonstrated extensive atherosclerotic abnormalities in the coronary arterial system. It is suggested that radiation-induced injury was a provocation of these precocious arterial abnormalities.
