BACKGROUND/AIMS: Endoscopic papillectomy (EP) has emerged as an alternative to surgery in the management of ampullary lesions. The aim of this study is to evaluate feasibility, efficacy, safety, outcome, and impact of EP in the management of benign ampullary lesions. MATERIALS AND METHODS: This is a multicenter, retrospective study of 44 patients who had EP of benign ampullary lesions. RESULTS: Over the 11-year period, 44 (55.7%) of 79 patients underwent EP for benign ampullary lesions...

Pancreatic panniculitis is a rare type that only occurs in 2-3% of all patients with pancreatic diseases. It is usually described in association with benign pancreatic disease and less commonly in association with pancreatic carcinoma. We describe a case of pancreatic panniculitis as the first manifestation of underlying ampullary adenocarcinoma and a new case of pancreatitis, panniculitis and polyarthritis (PPP-Syndrome). Pancreatic panniculitis may be the cutaneous manifestation of pancreatic allograft rejection after simultaneous pancreas-kidney transplantation...

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...

Introduction: Pancreatic ductal adenocarcinoma (PDAC) and ampulla of Vater adenocarcinomas (AVAC) are periampullary tumors. These tumors have overlapping symptoms and a common treatment, but present differences in their survival and biology. No recent studies in Mexico have been published that describe the clinicopathological characteristics of these tumors. Therefore, the aim of this study was to describe the clinicopathological characteristics of PDAC and AVAC in patients at a reference center in Mexico...

BACKGROUND: Blood group is reported to have an effect upon survival following pancreatoduodenectomy for pancreatic ductal adenocarcinoma. The effect of blood group is not known, however, among patients with other periampullary cancers. This study sought to review this. METHODS: Data were collected for a range of factors and survival outcomes from patients treated at two centres. Those with blood groups B and AB were excluded, due to small numbers. Patient survival was compared between patients with blood groups O and A using multivariable analysis which accounted for confounding factors...

Cutaneous metastases from an adenocarcinoma of the Ampulla of Vater are very rare, with only a few cases previously reported. We present here an additional case in a 57-year-old woman who complained of a painful growth on her frontal scalp that she had noticed 4 months earlier. Her medical history included an ampullary adenocarcinoma, which was diagnosed 4 years ago, excised through a Whipple procedure, and treated using chemotherapy and radiotherapy. The scalp biopsy showed a dermal and epidermotropic well-differentiated glandular neoplasm with abundant neutrophils within the luminae of the tumoral glands...

BACKGROUND: The evaluation of lymph node involvement is an essential component of cancer staging. Examining an inadequate number of lymph nodes potentially results in understaging. Current guidelines for lymph node retrieval for ampullary adenocarcinoma are based on data extrapolated from other periampullary malignancies and may not be applicable. The aim of this study was to determine the number of lymph nodes that should be examined in resection specimens to optimize staging in ampullary adenocarcinoma...

OBJECTIVE: Intraductal papillary mucinous neoplasms (IPMNs) are precursor lesions that can give rise to invasive pancreatic carcinoma. Although approximately 8% of patients with resected pancreatic ductal adenocarcinoma have a co-occurring IPMN, the precise genetic relationship between these two lesions has not been systematically investigated. DESIGN: We analysed all available patients with co-occurring IPMN and invasive intrapancreatic carcinoma over a 10-year period at a single institution...

INTRODUCTION: This study aimed to evaluate the impact of adjuvant radiotherapy in patients undergoing pancreaticoduodenectomy (PD) for ampullary adenocarcinoma. METHODS: Using the Surveillance, Epidemiology, and End Results, patients with non-metastatic ampullary adenocarcinoma between 2004 and 2013 were identified. Cancer-specific survival and overall survival were estimated using Kaplan-Meier and Cox regression to obtain adjusted hazard ratio of survival. RESULTS: In this study, 1106 patients with ampullary adenocarcinoma were identified, of which 27% received adjuvant radiotherapy and the remaining 73% (803/1106) patients did not receive any adjuvant radiotherapy...

We present here a case of transduodenal ampullectomy for an ampullary neoplasm coexisting with gastric and colon cancer. The patient was a 72-year-old man who was referred to our hospital with a positive fecal blood test. Colonoscopy revealed advanced cancer in the descending colon. As part of the preoperative examination, for the colonic cancer, upper gastrointestinal endoscopy was performed. Endoscopy showed a 2 cm elevated lesion(0'-II a type)with subserosalinfil tration on the small curvature side of the upper part of the stomach, and a 2 cm elevated lesion on the papilla of Vater...

REVIEW
Kyra B Berg, David F Schaeffer
Tumor budding, defined as single cells or clusters of less than five cells, is thought to be a histomorphologic marker of an aggressive tumor behavior mimicking the embryologic epithelial-mesenchymal transition, and has been well established in the past two decades as a poor prognostic factor in colorectal carcinoma. Slow uptake in routine reporting of this important pathologic prognostic feature was in part due to differing methods of assessment of budding reported in the literature, but has recently been clarified at a consensus conference on tumor budding in colorectal carcinoma...

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...

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...

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. 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...
