Remarkable regression of a lung recurrence from an undifferentiated embryonal sarcoma of the liver treated with a DC vaccine combined with immune cells: A case report

摘要

Undifferentiated embryonal sarcoma of the liver (UESL) is a rare malignant tumor that occurs predominantly in children and has a poor prognosis. Here, we report a novel case in which the UESL presented in the left lobe of the liver and metastasized into both lungs after surgical resection. The patient recovered after our administration of an immunotherapeutic combination of DCs (Dendritic Cells) and multi-immune cells, such as cytokine-induced killer cells (CIKs) and natural killer cells (NKs). After the third cycle of immunotherapy, a CT scan showed a remarkable regression of the lung metastases. This finding supports the conclusion that the DC-based treatment is a promising potential strategy for treating patients with relapsed UESL (C) 2014 The Authors. Published by Elsevier Inc.
