[Treatment of cases of cardiac surgery complicated with malignant neoplasms]. 
There were 10 (1.2%) cases of cardiac surgery complicated with malignant neoplasm among the total 863 cases of cardiac surgery in our hospital and 8 cases were treated also surgically against the neoplasms before and after the cardiac surgery.  They all underwent coronary artery bypass grafting, and in one case concomitant mitral valve replacement and abdominal aortic aneurysm resection were carried out.  The variety of the neoplasms in these cases were carcinomas of the stomach, pancreas, esophagus, renal pelvis, bile duct, colon and urinary bladder, and pleural mesothelioma.  These patients were discharged without operative death or major complication, and there was only one evidence of recurrence among the eight cases treated surgically for the neoplasms.  It was considered that patients who have critical cardiac problem also bearing neoplasmic combination could be treated excellently by means of both surgical measures.
