Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a tumor that has morphologically recognizable both adenocarcinoma and neuroendocrine carcinoma components comprising at least 30% of either components. MANEC occurring in the ampulla of Vater is extremely rare, and only 16 cases have been reported in the English language literature. In the present report, we describe the first case of MANEC of the ampulla of Vater with immunocytochemical analyses. An 82-year-old Japanese male was incidentally found to have a tumorous lesion in the ampulla of Vater...

INTRODUCTION: This study set to examine relative survival of patients with periampullary cancers undergoing pancreaticoduodenectomy (PD). METHODS: Using the Surveillance, End Results and Epidemiology (SEER) database, this study identified 9877 patients with non-metastatic pancreatic adenocarcinoma who underwent PD between 2004 and 2013. RESULTS: Ampullary carcinomas have the best survival among periampullary malignancies. Lymph node ratio is a significant prognostic factor, even when stratified by tumour types...

As the most common and most important cancer of the pancreas, with rapid mortality and now also as the third leading cause of cancer-related deaths in the United States, pancreatic ductal adenocarcinoma (PDAC) has become synonymous with "pancreas cancer". PDAC is also the prototype of the "pancreatobiliary-type" adenocarcinomas, along the biliary tract, ampullary and gallbladder cancers with the similar morphology and behavior. Recent molecular profiling studies have identified distinct subsets of PDAC, potentially with different behaviors and targetability...

Pancreatic ductal adenocarcinoma (PDAC) continues to carry the lowest survival rates among all solid tumors. A marked resistance against available therapies, late clinical presentation and insufficient means for early diagnosis contribute to the dismal prognosis. Novel biomarkers are thus required to aid treatment decisions and improve patient outcomes. We describe here a multi-omics molecular platform that allows for the first time to simultaneously analyze miRNA and mRNA expression patterns from minimal amounts of biopsy material on a single microfluidic TaqMan Array card...

LESSONS LEARNED: Panitumumab has no clinical activity in metastatic RAS wild-type small bowel adenocarcinoma (SBA) and ampullary adenocarcinoma (AAC), possibly due to the foregut and midgut derivation of small bowel and ampulla.These results, along with findings from genomic characterization of SBA, suggest that SBA represents a unique intestinal malignancy and treatments should not be habitually extrapolated from colorectal cancer.Further studies evaluating the benefit of targeted therapies exclusively in SBA and AAC are warranted...

BACKGROUND: Circulating tumor cells (CTCs) are an important topic of investigation for both basic and clinical cancer research. In this prospective study, we evaluated the clinical role of CTCs in ampullary cancer. METHODS: We analyzed blood samples from 62 consecutively diagnosed patients with ampullary adenocarcinoma and 24 healthy controls for their CTC content. Combined data from immunostaining of CD45, 4',6-diamidino-2-phenylindole (DAPI), and fluorescence in situ hybridization with a chromosome 8 centromere (CEP8) probe were used to identify CTCs; cells that were CD45-/DAPI + /CEP8 > 2 were considered CTCs...

We previously reported on a family with hereditary lung cancer, in which a germline mutation in the transmembrane domain (G660D) of avian erythroblastic leukemia viral oncogene homolog 2 (erb-b2 receptor tyrosine kinase 2) (ERBB2; human epidermal growth factor receptor 2 [HER2]) seemed to be responsible for the cancer predisposition. Although few data are available on treatment, anti-ERBB2 therapeutic agents may be effective for ERBB2-mutant cancers. The familial lung cancer patient in one of the authors' institutes developed bone metastasis with enlarging lung tumors and was treated with the ERBB2 inhibitor afatinib...

Several markers of pancreatobiliary lineage have been described in the literature. However, none have demonstrated sufficient specificity and sensitivity to warrant diagnostic use. We evaluated the utility of T-complex-associated-testis-expressed 3 (TCTE3) as a pancreatobiliary marker. A set of 247 adenocarcinomas from the gastrointestinal (GI) tract was identified including 18 from the gastroesophageal junction (GEJ), 29 stomach, 17 ampullary, 62 pancreatic, and 16 common bile duct and gallbladder (CBD/GB), 13 non-ampullary small intestine, 32 colon, and 24 rectum...

BACKGROUND: Duodenal polyposis is a manifestation of adenomatous polyposis that predisposes to duodenal or ampullary adenocarcinoma. Duodenal polyposis is monitored by upper GI endoscopies and may require iterative resections and prophylactic radical surgical treatment when malignancy is threatening. OBJECTIVE: The purpose of this study was to evaluate severity scoring for surveillance and treatment in a large series of duodenal polyposis. DESIGN: From 1982 to 2014, every patient surveyed by upper GI endoscopies for duodenal polyposis was included...

BACKGROUND: The prognostic impact of pathologic response to preoperative therapy on patients with duodenal adenocarcinoma (DA) and ampullary adenocarcinoma (AMPA) has not been established. METHODS: A retrospective review of 266 patients who underwent curative resection for DA (n = 97) or AMPA (n = 169) during 1993-2015 was performed. For patients who underwent preoperative therapy, the pathologic response was systematically evaluated and classified as major (0-49% of viable residual tumor cells) or minor (≥ 50% of viable residual tumor cells)...

Adenomas of the ampulla of Vater are distinctly rare, representing <10% of periampullary neoplasms. Very few reports of the cytologic features of ampullary adenomas are present in literature, particularly in bile duct brushing samples. A case report and review of the literature is presented. The typical cytologic features of ampullary adenomas on cytologic preparations include tall, thin columnar cells with mildly hyperchromatic elongated nuclei and nuclear pseudostratification, in a relatively clean background...

Presence of Courvoisier's or double duct signs in a jaundiced patient is suggestive of malignant obstruction of the pancreaticobiliary ductal system. The oncologic impact of the simultaneous occurrence of these signs on the survival of patients with periampullary cancer is unknown. We report a case of obstructive jaundice secondary to an ampullary cancer demonstrating the Courvoisier's sign on clinical examination and a double duct sign on imaging. The patient underwent a pancreaticoduodenectomy which confirmed an ampullary adenocarcinoma...

Peripheral neuropathy is the most common dose-limiting toxicity associated with oxaliplatin. We report on a 61-year-old female patient with advanced primary ampullary adenocarcinoma who received 35 cycles of FOLFIRINOX (5-fluorouracil, irinotecan, and oxaliplatin) chemotherapy. The patient has tolerated this treatment without developing significant peripheral neuropathy.

Paraduodenal pancreatitis, also known as groove pancreatitis, is a rare form of chronic pancreatitis that masquerades as pancreatic adenocarcinoma affecting the pancreaticoduodenal groove, a potential space between the head of the pancreas, duodenum, and common bile duct. Two forms of groove pancreatitis have been described. The segmental form involves the pancreatic head with development of scar tissue within the groove, whereas the pure form affects the groove only, sparing the pancreatic head. Imaging findings of groove pancreatitis often overlap with primary duodenal, ampullary, or pancreatic neoplasms, which often results in a diagnostic challenge...

INTRODUCTION: The ampulla of Vater consists of papilla, common channel, distal common bile duct and the distal main pancreatic duct. Ampullary carcinomas arise from two different types of mucosa, reflecting their broad histomorphological spectrum. Adenocarcinomas originating in the ampulla of Vater are classified as having either 'Intestinal' or 'Pancreatobiliary' type of differentiation. Pancreatobiliary type has consistently shown a worse prognosis. Various types of mucins are distributed in normal tissues and gastrointestinal tumours...

PURPOSE: Attempts have been made to revise the nodal stage due to simplicity of current N staging system in ampullary adenocarcinoma. However, because of the disease rarity, there have only been a few studies assessing the prognostic impact of lymph node (LN) parameters. METHODS: We retrospectively analyzed 120 patients who underwent radical resection followed by adjuvant chemoradiotherapy for ampullary adenocarcinoma. The effect of LN parameters (number of total harvest LNs, number of metastatic LN (MLN), lymph node ratio (LNR), and log odds of positive LNs (LODDS)) on overall survival (OS), locoregional relapse-free survival (LRFS) and distant metastasis-free survival were evaluated...
