- Because of cardiopulmonary toxicity seen in patients on other studies, patients with a symptomatic cardiac disease should be excluded; patients with a history of coronary artery disease or mediastinal radiation should undergo testing of ventricular function (cardiac echocardiogram, MUGA or equivalent) and are eligible if LVEF is >= 45%; if there is a history of prior pulmonary disease then pulmonary function tests should be performed and patients are eligible if FEV1 >= 1 liter
