Meanings of malignant pancreatic endocrine tumor in English

In 1947, a patient with metastatic islet cell tumor was treated for intractable ulcer disease at the University of Chicago Medical Center.

We report three cases of cystic islet cell tumors, two caused by gastrinomas and the other by an islet cell carcinoma.

Overall survival was 61% and 35% at 5 and 10 years, respectively, with no difference between carcinoid and islet cell tumors.

A retrospective review at our tertiary referral center (from 1976 to 1999) identified 27 patients with primary duodenal carcinoid lesions, excluding functional islet cell tumors.

Pancreatic endocrine neoplasms (PENs) are rare tumors, and little is known about their genetic and chromosomal alterations.

One patient had a ductal adenocarcinoma, two presented with pancreatic endocrine neoplasms and the last one had an intraductal papillary mucinous neoplasia.

We discuss the diagnosis of pancreatic ductal adenocarcinoma and of other pancreatic epithelioid tumors including pancreatic endocrine neoplasms, solid pseudopapillary tumors, and acinar cell carcinomas.

Pancreatic neuroendocrine neoplasms (PanNENs) have an unpredictable clinical course that varies from indolent to highly malignant.

Methods: We examined a prospectively maintained, single-institution database to identify patients who underwent potentially curative resection of non-metastatic primary pancreatic neuroendocrine neoplasms.
