Pancreatoblastoma: response to chemotherapy.

Two cases of pancreatoblastoma in children are reported here. Only biopsies were made at laparotomy as surgical resection by duodeno-pancreatectomy was not possible. In both children a dramatic response was observed with chemotherapy: doxorubicin plus cisplatin for one, cyclophosphamide, actinomycin D, bleomycin, vinblastine sulfate, and cisplatin for the other. After completion of the chemotherapy the first patient had a local resection; then he had radiotherapy. He is alive in first remission 40 months after the end of the treatment. In the second patient, regional recurrence occurred 8 months after chemotherapy was ended. A transient second remission was obtained with ifosfamide plus etoposide alternating with epirubicin plus vincristine. The patient died 36 months after the diagnosis. Therefore, these two cases suggest that chemotherapy may be proposed before any attempt at surgical excision. Nevertheless, early consolidation by radical resection or irradiation must be considered.
