Alpha-fetoprotein-positive carcinoma of the pancreas: a case report.
We report on the case of a 19-year-old male with an alpha-fetoprotein (AFP)-producing acinar cell carcinoma of the pancreas. Tumour markers other than AFP were normal. Because of inoperability, a combined radiochemotherapy was initiated with a hyperfractionated dose of 44.8 Gy. Initially, the tumour showed a good response to irradiation and 5-fluorouracil (5-FU) application, and therapy showed sufficient local control. After combined radio-chemotherapy, AFP levels declined from about 3000 ng/ml (reference area: 0-7 ng/ml) to 18 ng/ml, but increased when widespread metastasis appeared. The patient died 18 months after the initial therapy due to general tumour progression. Originally, AFP was thought to be specific to hepatocellular carcinoma and germ cell tumours. Rarely has it been reported in other malignancies. Rare cases of acinar cell carcinomas of the pancreas were found to express AFP. Our patient is the youngest reported in the literature to date. When present, AFP expression is useful for diagnosis and as a marker for monitoring therapeutic response and recurrence of the disease.
