the use of agents with proarrhythmic potential (e.g., quinidine, procainamide, disopyramide, sotalol, probucol, haloperidol, risperidone, indapamide, flecainide) is not recommended while on protocol therapy~* Patients with class I New York Heart Association (NYHA) heart failure are eligible; patients with a history of class II NYHA heart failure are eligible, provided they meet at least one of the following criteria:~  * Patients with a history of class II heart failure who are asymptomatic on treatment~ * Patients with prior anthracycline exposure~ * Patients who have received central thoracic radiation that included the heart in the radiotherapy port~* Patients with a history of class III or IV NYHA heart failure within 12 months prior to registration are not eligible~* No myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft or stenting, cerebrovascular accident or transient ischemic attack within the last year~* Patients with hypertension that cannot be controlled by medications (\> 150/100 mmHg despite optimal medical therapy) are not eligible~* Patients who require use of therapeutic anticoagulation for thromboembolic disease are not eligible; Note: low doses of coumadin (up to 2 mg daily) are permitted for prophylaxis of thrombosis~* No history of venous thrombosis, pulmonary embolism, or hypercoagulopathy syndrome~* No history of pulmonary hemorrhage, bleeding diathesis, or evidence of hemoptysis; patients with blood-tinged or blood-streaked sputum will be permitted on study if the hemoptysis amounts to less than 5 ml of blood per episode and less than 10 ml of blood per 24-hour period in the best estimate of the investigator~* Patients with a history of hypothyroidism are eligible, provided they are currently euthyroid~* None of the following within 28 days of beginning treatment: abdominal fistula, gastrointestinal perforation, intra-abdominal abscess, serious or non-healing wound, ulcer, or bone fracture~* The following inhibitors of cytochrome P450 3A4 (CYP3A4) are prohibited within 7 days before beginning and during treatment with sunitinib: azole antifungals (ketoconazole, itraconazole), diltiazem, clarithromycin, erythromycin, verapamil, delavirdine, and human immunodeficiency virus \[HIV\] protease inhibitors (indinavir, saquinavir, ritonavir, atazanavir, nelfinavir); the following inducers of CYP3A4 are prohibited within 12 days before beginning and during treatment with sunitinib: rifampin, rifabutin, carbamazepine, phenobarbital, phenytoin, St. John?s Wort, efavirenz, tipranavir; other inhibitors and inducers of CYP3A4 may be used if necessary, but their use is discouraged~* Patients unable to take oral medication are not eligible~* Granulocytes \>= 1,500/mcl~* Platelet count \>= 100,000/mcl~* Total bilirubin =\< 1.5 x upper limit of normal (ULN)~* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT)=\< 2.5 x ULN; patients with liver metastases may have AST and ALT =\< 5 x ULN; all other patients will have AST and ALT =\< 2.5 x ULN~* Creatinine =\< 1.5 mg/dl
