Primary cardiac neoplasms. Early and late results of surgical treatment in 42 patients

Abstract

Forty-two patients underwent resection of primary cardiac neoplasms at Stanford University Medical Center and the Palo Alto Veterans Administration Medical Center between 1961 and 1986. A total of 27 atrial myxomas, seven benign nonmyxomatous tumors, and eight malignant tumors were resected. The mean age was 47 years (range 8 to 79) in 27 female and 15 male patients. The clinical presentations included congestive heart failure in 24 patients, palpitations in nine, neurologic symptoms in six, recurrent cardiac tamponade in three, vasculitis in two, and chest pain in two. Thirty-one of 34 benign lesions were completely resected, although one patient required cardiac transplantation to resect completely an "inoperable" benign tumor. All gross tumor was resected in four of eight patients with malignant lesions. All patients survived operation, but three with malignant disease died within 30 days. Late outcome was known for 41 of 42 (98%) patients. Total follow-up for the series was 200.1 patient-years, for an average of 4.7 years (range 1 month to 18 years). Excellent early and late results were obtained in patients with benign lesions, as there was no known tumor recurrence even if resection was incomplete. Effective palliation and local control of disease is possible with extensive resection of malignant primary tumors, but more effective adjuvant therapy will be necessary to improve long-term prognosis.
