Autologous stem cell transplantation as treatment modality in a patient with relapsed pancreatoblastoma.

Pancreatoblastoma (PB) is a rare malignant neoplasm of the pancreas, which occurs mostly during childhood. Presently, the optimal treatment strategy is neither clear nor uniform for patients in advanced stages, in particular those with metastasis, inoperable, or recurrent tumors. To our knowledge, until now, only one patient with PB has been treated with hematopoietic stem cell transplantation (HSCT) following aggressive chemotherapy and surgical resection. Here we report the second case of PB who was treated with aggressive chemotherapy combined with autologous peripheral blood stem cell transplantation.
