Value of Quantitative DNA Analysis in Endocrine Tumors of the Pancreas
1997
The diagnosis of malignancy can be difficult in endocrine tumors of the pancreas. Moreover prognostically relevant factors are not available. The aim of this study was to evaluate retrospectively whether the DNA distribution pattern can differentiate between benign and malignant pancreatic endocrine tumors and secondly whether the DNA content of tumor cells gives prognostic information.Image cytometry of paraffin-embedded tumor material of 42 pancreatic endocrine tumors.In 27 benign endocrine pancreatic tumors (25 insulinomas, 2 benign nonfunctioning endocrine tumors) we could differentiate between 6 diploid, 15 hypotriploid and 6 triploid DNA histograms. In 15 malignant endocrine tumors of…
Ultrasonic demonstration of small pancreatic islet cell tumors.
1982
In three patients real-time sonography successfully localized small pancreatic islet cell tumors measuring 7, 8, and 17 mm in size. Ultrasound is suggested as the initial radiologic examination for localization of endocrine pancreatic tumors. If ultrasound is negative or equivocal, computerized tomography, arteriography, and pancreatic venous sampling are indicated.
A method of reconstruction after pancreaticoduodenectomy for pancreatic malignancies in very young children: Two cases reports
2016
Abstract Pancreatic tumors are very rare diseases in very young children. Most information about those diseases in children was published in cases reports. Due to the rare nature of pancreatic tumors in children, there remains the absence of diagnostic algorithms, clear radiographic and morphological assessments as well as evidence based best treatment options. Because of the young age of patients and the rare occurrence of pancreatic neoplasms, tumor detection remains poor. For malignancies affecting the head of the pancreas the only possibility for achieving clear surgical margins is performing a pancreaticoduodenectomy (PD). We describe two cases of diagnostic and treatment of pancreatic…
