Key result
Surgical resection of cavoatrial metastatic liposarcoma using cardiopulmonary bypass and circulatory arrest achieves 8-year survival.
Case Report (n=1)
Surgical resection using cardiopulmonary bypass with hypothermic circulatory arrest can be successfully performed for cavoatrial metastatic dedifferentiated liposarcoma, potentially offering long-term survival.
Supports feasibility in select cases; leaves open generalizability and need for prospective data in cavoatrial sarcomas.
A patient had undergone surgical resection twice for primary and metastatic dedifferentiated liposarcomas. Follow-up computed tomography revealed a new tumor mass located at the cavoatrial junction. Prompt surgical resection of the tumor with thrombectomy was successfully performed using cardiopulmonary bypass with hypothermic circulatory arrest. We report a rare case of a patient surviving for 8 years after the first tumor resection despite the poor prognosis of metastatic or recurrent liposarcoma.

Matsumoto et al. (2021) conducted a case report in Cavoatrial metastatic dedifferentiated liposarcoma (n=1). Surgical resection with thrombectomy using cardiopulmonary bypass with hypothermic circulatory arrest was evaluated on Survival / successful resection. Surgical resection of a cavoatrial metastatic dedifferentiated liposarcoma using cardiopulmonary bypass and hypothermic circulatory arrest was successful, with the patient surviving 8 years.
