Clinical implication of surgical resection for the rare cardiac tumors involving heart and great vessels.

This study aimed to investigate the clinical implication of surgical resection for the malignancies of heart and great vessels. Between January 2001 and May 2011, a retrospective review of the results in 12 patients was conducted. There were 6 patients with primary cardiac tumor including leiomyosarcoma, angiosarcoma, undifferentiated type sarcoma and malignant fibrous histiocytoma. The remaining 6 patients had the metastatic tumors or adjacent invasion to the heart and great vessels. Six of seven patients who underwent complete resection had no evidence of recurrence. However, four of five patients who underwent incomplete resection or biopsy showed local recurrence or distant metastasis of residual tumor, and one of them required reoperation for recurred tumor. In-hospital mortality was 8.3% and the mean survival of all patients was 22.2 ± 6.1 months. Survival of the incomplete resection group, except for the two biopsy cases, was 25.9 ± 7.9 months, and there was no mortality in the complete resection group. Therefore, clinical outcomes in patients who had malignancies of the heart and great vessels may be improved when the aggressive and complete resection, or possible debulking for palliation, was performed. Moreover, adjuvant multimodality therapy may be imperative to prevent recurrence or metastasis, and to provide improved survival.
