From December 1981 to December 1989, 20 patients with primary or recurrent retroperitoneal sarcoma received 4000 to 5000 cGy of external beam radiation therapy (EBRT) in conjunction with surgical resection and intraoperative radiation therapy (IORT). Seventeen of 20 patients underwent complete (14 patients) or partial (3 patients) resection. Three patients had shown evidence of metastases after EBRT by the time of surgery. ⋯ Five patients did not receive IORT at the time of resection because of the extensive size of the tumor bed. Three of these patients are disease-free with one patient alive with lung metastases and one patient dying of hepatic metastases. Aggressive radiation and surgical procedures appear to provide satisfactory resectability and local control with acceptable tolerance.

Twenty long-term survivors of childhood cancer underwent exercise echocardiography to evaluate possible late anthracycline-induced cardiac toxicity. Ten patients ages 10 to 20 years had received anthracyclines, and ten patients ages 8 to 27 years had not received anthracyclines as part of their medical regimen. ⋯ There were no significant differences in work performed, or increase in heart rate or blood pressure with exercise between the groups. These results suggest that subtle abnormalities in myocardial function exist which become apparent only after exercise in survivors of childhood cancer who have received anthracyclines and have normal resting cardiac function.
