The Results of Pancreatic Resections and Long-Term Survival for Pancreatic Ductal Adenocarcinoma: A Single-Institution Experience.

Objectives: Since the early 1990s, low long-term survival rates following pancreatic surgery for pancreatic ductal adenocarcinoma have challenged us to improve treatment. In this series, we aim to show improved survival from pancreatic ductal adenocarcinoma during the era of centralized pancreatic surgery.

Methods: Analysis of all pancreatic resections performed at Helsinki University Hospital and survival of pancreatic ductal adenocarcinoma patients during 2000-2013 were included.

Isolated subcutaneous implantation of a borderline ovarian tumor: A case report and review of the literature.

Laparoscopy-related tumor implantations of gynecological malignancies into the subcutaneous tissue are rarely diagnosed. We report an interesting case of a 46-year-old female who presented with an abdominal subcutaneous metastasis of a borderline ovarian tumor. The patient received a laparoscopic unilateral adnexectomy for a solid-cystic tumor of the right ovary.

A registry-based study of thyroid paraganglioma: histological and genetic characteristics.

The precise diagnosis of thyroid neoplasias will guide surgical management. Primary thyroid paraganglioma has been rarely reported. Data on prevalence, immunohistochemistry (IHC), and molecular genetics in a systematic series of such patients are pending.

Histopathologic features and microsatellite instability of cancers of the papilla of vater and their precursor lesions.

The prevalence and development of microsatellite instability (MSI) and underlying mismatch repair (MMR) deficiency in the carcinogenesis of adenocarcinomas of the papilla of Vater and their precursor lesions are not well established. We analyzed 120 ampullary adenomas (31 pure adenomas and 89 carcinoma-associated adenomas) and 170 pure adenocarcinomas for MSI, immunohistochemical expression of MMR proteins and specific histopathologic features. The most common histologic subtype was intestinal (46.

Sperm-associated antigen 1 is expressed early in pancreatic tumorigenesis and promotes motility of cancer cells.

Sperm-associated antigen 1 (SPAG1) was recently identified in a rare form of infertility where anti-SPAG1 antibodies derived from the serum of an infertile woman were reported to cause sperm agglutination. Except for its expression and potential role in spermatogenesis, the function of SPAG1 is completely unknown. The unexpected finding of high levels of SPAG1 expression in pancreatic adenocarcinoma compared to normal pancreatic tissue in our previous cDNA array experiments prompted us to look in more detail at the expression and role of this gene in a panel of normal and malignant human tissues as well as in a larger series of pancreatic cancer specimens.
