Cardiac liposarcoma-a review of outcome after surgical resection

This review was performed to pool the current surgical strategies for cardiac liposarcoma.

A literature search was performed and all studies published in full-text or abstract forms were eligible for inclusion without applying any language restrictions. Case reports without surgical intervention, reporting noncardiac liposarcoma, animal cases, or review articles were excluded after initial abstract review. Analyzed postoperative outcomes included intraoperative and in-hospital mortality, longest reported survival, and recrudescence.

After a critical evaluation 53 unique surgically treated case reports published between the years 1966 and December 2012 were included in this review. Most of the reported cardiac liposarcoma are myxoid (49.1%), pleomorphic liposarcoma occur with a prevalence of 20.8%, and well-differentiated tumors are observed in 13.2%. One-year survival rate increases the more differentiated the tumor is categorized: 54.5% for pleomorphic, 65.4% for myxoid, and 100% for well-differentiated liposarcoma (p = 0.096).

Total surgical resection of cardiac liposarcoma is the only curative option, as it tends to local and distant recurrence. Therefore, a frequent follow-up examination should be considered.
