Pancreatic Mass in a Patient with a History of Resected Renal Cell Carcinoma and Resected Adenocarcinoma of the Ampulla of Vater: A Case Report.

J Pancreat Cancer 2018 1;4(1):41-44. Epub 2018 Aug 1.

Department of Surgery, Sidney Kimmel Medical College at Thomas Jefferson University Hospital, Philadelphia, Pennsylvania.

Metastases of renal cell carcinoma (RCC) to the pancreas are rare, whereas recurrence of pancreatic ductal adenocarcinoma (PDA) or a primary periampullary cancer is far more common. The time elapsed between a primary tumor and a new mass can aid in differentiation between the two. A 70-year-old man with a history of RCC status after left nephrectomy and ampullary adenocarcinoma status after pancreaticoduodenectomy presents with an incidentally found mass in his remnant pancreas.

High-grade precursor lesions can be used as surrogate markers to identify the epicenter of periampullary carcinomas.

Hum Pathol 2018 Sep 24. Epub 2018 Sep 24.

Department of Pathology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea. Electronic address:

Identifying the accurate origin of periampullary cancers is important, because different origins may trigger different clinicopathologic behaviors. The presence of intraepithelial precursor lesions, including high-grade pancreatic intraepithelial neoplasias (PanINs) and/or high-grade biliary intraepithelial neoplasias (BilINs), may be suggestive of the origin of the periampullary carcinoma in challenging cases. To prove the usefulness of high-grade intraepithelial precursor lesions to identify the origin of ambiguous periampullary cancers, the status and grades of PanINs and BilINs were evaluated in 256 periampullary carcinomas with a well-defined cancer origin as a test set, including 114 pancreatic cancers, 82 distal bile duct cancers, 54 ampullary cancers, and 6 duodenal cancers, and 112 periampullary carcinomas with clinically equivocal epicenter either by radiologic imaging used as a validation set.

Neutrophil-to-lymphocyte ratio as a predictor of postoperative morbidity in patients with distal cholangiocarcinoma.

Mol Clin Oncol 2018 Oct 14;9(4):362-368. Epub 2018 Aug 14.

Department of Surgery, Kitasato University School of Medicine, Sagamihara, Kanagawa 252-0374, Japan.

Systemic inflammatory-, immunological- and nutritional-based indices, such as the neutrophil-to-lymphocyte ratio (NLR), the prognostic nutritional index (PNI) and the Glasgow prognostic score (GPS), are drawing considerable research attention to predict the long-term prognosis of many types of cancer. Recently, these parameters have also been reported to be useful in predicting postoperative morbidity in several fields, including colorectal and otolaryngological cancer. However, while distal cholangiocarcinoma exhibits a high morbidity rate, its risk factors of morbidity have not yet been established. Read More

Pancreatic and bile duct cancer circulating tumor cells (CTC) form immune-resistant multi-cell type clusters in the portal venous circulation.

Cancer Biol Ther 2018 1;19(10):887-897. Epub 2018 Aug 1.

a Departments of Translational Research (SAL, RS, AJOA, MS, EG, Y-PS); Surgical Oncology (JPA), Florida Hospital Cancer Institute , Orlando , FL , USA.

Circulating tumor cells (CTC) enter the blood from many carcinomas and represent a likely source of metastatic dissemination. In contrast to the peripheral circulation, KRAS mutation- positive CTC thrive in the portal venous blood of patients with pancreatic ductal adenocarcinoma (PDAC). To analyze the essential interactions that contribute to carcinoma CTC growth and immune resistance, portal venous blood was collected during pancreatico-duodenectomy in 41 patients with peri-ampullary pathologies (PDAC = 11; ampullary adenocarcinoma (AA) = 15; distal cholangiocarcinoma (CC) = 6; IPMN = 7; non-malignant pancreatitis = 2).

Investigation of HNF-1B as a diagnostic biomarker for pancreatic ductal adenocarcinoma.

Biomark Res 2018 27;6:25. Epub 2018 Jul 27.

6Department of Pathology, Massachusetts General Hospital, Boston, MA USA.

Background: Diagnosing pancreatic ductal adenocarcinoma (PDAC) in the setting of metastasis with an unknown primary remains very challenging due to the lack of specific biomarkers. HNF-1B has been characterized as an important transcription factor for pancreatic development and was reported as a biomarker for clear cell subtype of PDAC.

Methods: To investigate the diagnostic role of HNF-1B for PDAC, we used tissue microarray (TMA) and immunohistochemistry (IHC) to characterize HNF-1B expression in a large cohort of carcinomas, including 127 primary PDACs, 47 biliary adenocarcinomas, 17 metastatic PDACs, and 231 non-pancreaticobiliary carcinomas.

MiR-21 up-regulation in ampullary adenocarcinoma and its pre-invasive lesions.

Pathol Res Pract 2018 Jun 1;214(6):835-839. Epub 2018 May 1.

Department of Medicine (DIMED), University of Padua, Padua, PD, Italy. Electronic address:

Poor information is available on the molecular landscape characterizing the carcinogenetic process leading to ampullary carcinoma. MiR-21 is one of the most frequently up-regulated miRNAs in pancreatic adenocarcinoma, a tumor sharing similar molecular features with ampullary adenocarcinomas (AVCs), above all with the pancreatic-biliary type. We profiled, by in situ hybridization (ISH), miR-21 expression in a series of 26 AVCs, 50 ampullary dysplastic lesions (35 low-grade [LG-IEN] and 15 high-grade [HG-IEN]) and 10 normal duodenal mucosa samples.
