BACKGROUND: Capecitabine with oxaliplatin (CAPOX) has previously demonstrated clinical activity in patients with small bowel adenocarcinoma (SBA) and ampullary adenocarcinoma (AAC). Herein, the authors conducted a phase 2 trial to evaluate the benefit of adding bevacizumab to CAPOX. METHODS: In this phase 2, single-arm, single-center, open-label study, patients aged ≥18 years with untreated, advanced SBA or AAC were recruited. Patients received capecitabine at a dose of 750 mg/m(2) orally twice daily on days 1 to 14, oxaliplatin at a dose of 130 mg/m(2) intravenously on day 1, and bevacizumab at a dose of 7...

Tumors of the pancreas, the ampulla of Vater, and the extrahepatic and intrahepatic bile ducts have significant histological similarities due to the common embryonic origin of the pancreatobiliary system. This obviates the need for discovery of biomarkers with diagnostic and prognostic value for these tumors. Mucins, especially MUC-1, -2, -4 and -5AC, are important candidates for developing into such reliable biomarkers. Increased expression of MUC1 occurs in pancreatic ductal adenocarcinomas and is associated with increased degrees of dysplasia in pancreatic intraepithelial neoplasia (PanIN)...

Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like)...

Importance: Patients with periampullary adenocarcinomas have widely variable survival. These cancers are traditionally categorized by their anatomic location of origin, namely, the duodenum, ampulla, distal common bile duct (CBD), or head of the pancreas. However, they can be alternatively subdivided histopathologically into intestinal or pancreaticobiliary (PB) types, which may more accurately estimate prognosis. Objectives: To identify factors associated with survival in patients with periampullary adenocarcinomas and to compare survival between those having intestinal-type or PB-type cancers originating from the duodenum, ampulla, or distal CBD with those having pancreatic ductal adenocarcinoma (PDAC)...

INTRODUCTION: Subclassification of ampullary adenocarcinomas into intestinal and pancreatobiliary type has prognostic and therapeutic implications. Immunohistochemical staining against specific biomarkers has been proven to be a useful adjunct in determining the exact histotype. Furthermore the immunohistochemical profile is suggestive of the molecular pathogenic mechanisms through which the tumor evolved. The aim of this study was to correlate p53, MDM2, CK7, CK20, MUC1, MUC2 and CDX2 expression in ampullary adenocarcinomas with the type of differentiation and patients' survival...

Caracinosarcomas are tumours with diverse epithelial and mesenchymal differentiation. They most commonly occur in the female reproductive organs and upper aero digestive tract. They are relatively rare in the gastrointestinal tract and affect the oesophagus most commonly. Ampullary carcinosarcomas are exceptionally rare. We report a case of ampullary carcinosarcoma in a 67-year-old male, with osteosarcomatous, small cell carcinoma and conventional adenocarcinoma components. To the best of our knowledge, this is the first reported case of its kind...

Histologic classification of ampullary carcinomas as intestinal versus pancreatobiliary is rapidly becoming a part of management algorithms, with immunohistochemical classification schemes also being devised using this classification scheme as their basis. However, data on the reproducibility and prognostic relevance of this classification system are limited. In this study, five observers independently evaluated 232 resected ampullary carcinomas with invasive component >3 mm. Overall interobserver agreement was 'fair' (κ 0...

Catheter-based radiofrequency ablation (RFA) delivered during endoscopic retrograde cholangiopancreatography (ERCP) may represent a viable treatment option for intraductal extension of ampullary neoplasms, however, clinical experience with this modality is limited. After ampullary resection, 4 patients with intraductal extension underwent adjunctive RFA of the distal bile duct. All patients received a temporary pancreatic stent to reduce the risk of pancreatitis, as well as a plastic biliary stent to prevent biliary obstruction...

BACKGROUND: Ampullary adenocarcinoma is a rare gastrointestinal cancer associated with diverse outcomes due to clinical and pathological heterogeneity. Standardized methods to better prognosticate and inform therapeutic selection for ampullary adenocarcinoma are needed. This study explored the novel use and potential prognostic utility of a 92-gene cancer classifier in ampullary adenocarcinomas. METHODS: In this prospectively-defined, blinded study of ampullary adenocarcinoma [N =54; stage T3 or higher (57 %); Grade III (44 %); Node positive (55 %)], the performance of a 92-gene classifier was examined to predict the ampullary subtype that was derived from histomorphological examination of resected ampullary samples...

BACKGROUND: The therapeutic role of endoscopic papillectomy (EP) for early ampullary cancer (AC) is still controversial. The aim of the present study was to evaluate the curative potential of EP for early AC and to identify predictors of lymph node metastases (LNMs). METHODS: We retrospectively reviewed 173 patients who were prospectively included in a database and who underwent EP between 1999 and 2013. Adenocarcinoma was present in 28 resected specimens. An additional surgery was proposed in cases of duodenal submucosal infiltration, duct ingrowth, R1 resection or lymphovascular invasion...

Ampullary adenocarcinoma (A-AC) is a rare malignancy arising from the ampulla of Vater. KRAS mutation is detected in 30-40% of patients with A-AC, but its clinical implication and prognostic value are not well described. We conducted this meta-analysis to investigate the association between KRAS mutation and prognosis in patients with A-AC. We searched Pubmed, MEDLINE, EMBASE, and the Cochrane Library databases for articles including following terms in their titles, abstracts, or keywords: 'ampullary or periampullary or ampulla of vater', 'cancer or carcinoma', and 'KRAS'...

Bile acids are potential carcinogens in gastrointestinal cancer, and interact with nuclear and membrane receptors to initiate downstream signaling. The effect of TGR5 [also known as G protein-coupled bile acid receptor 1 (GPBAR1)] on cancer progression is dependent on the tissue where it is activated. In this report, the function of TGR5 expression in cancer was studied using a bioinformatic approach. TGR5 expression in ampullary adenocarcinoma and normal duodenum was compared by western blotting, reverse transcription polymerase chain reaction, and immunohistochemistry (IHC)...

Distal common bile duct carcinoma is a poorly characterized entity for reasons such as variable terminology and difficulty in determining site of origin of intrapancreatic lesions. We compared clinicopathologic features of pancreatobiliary-type adenocarcinomas within the pancreas, but arising from the distal common bile duct, with those of pancreatic and ampullary origin. Upon careful review of 1017 pancreatoduodenectomy specimens with primary adenocarcinoma, 52 (5%) qualified as intrapancreatic distal common bile duct carcinoma...

Mixed adenoneuroendocrine carcinomas (MANECs) are rare biphasic tumour types, which are morphologically recognisable as both gland-forming and neuroendocrine neoplasms. Within the gastrointestinal tract, MANECs occur predominantly in the stomach or colorectum. The present study described a case of a MANEC originating from the ampullary region. The patient presented with widespread metastatic disease. Biopsy samples obtained from the ampullary primary tumour disclosed a complex lesion with adenocarcinoma and neuroendocrine small cell carcinoma components, positive for the intestinal transcription factor caudal type homeobox-2 and for neuroendocrine markers, including chromogranin A, synaptophysin, cluster of differentiation 56/neural cell adhesion molecule...

BACKGROUND/AIMS: Ampullary carcinoma is a rare tumour with a high resectability rate. There is an increasing body of evidence indicating not only tumour-related factors, but also jaundice influence survival following curative resection. Several modalities for preoperative biliary drainage are available; however, routine preoperative endoscopic biliary drainage (PEBD) is not recommended. There is no sufficient data regarding the impact of PEBD on long-term outcomes. The aim of our study was to identify predictive factors of survival with special regard to PEBD in patients undergoing curative resection for ampullary carcinoma...

BACKGROUND & AIMS: Less than 10% of registered drug intervention trials for pancreatic ductal adenocarcinoma (PDAC) include a biomarker stratification strategy. The ability to identify distinct mutation subsets via endoscopic ultrasound fine needle aspiration (EUS FNA) molecular cytology could greatly aid clinical trial patient stratification and offer predictive markers. We identified chemotherapy treatment naïve ampullary adenocarcinoma and PDAC patients who underwent EUS FNA to assess multigene mutational frequency and diversity with a surgical resection concordance assessment, where available...

BACKGROUND: There is no universally accepted protocol for gross examination of pancreaticoduodenectomy specimens. Standardized protocol (SP), known as Leeds Pathology Protocol, was previously validated in pancreatic adenocarcinoma. In this study we aimed to assess usefulness of SP in a series of specimens with pancreatic, ampullary, and duodenal malignant neoplasms other than adenocarcinomas. MATERIALS AND METHODS: SP was based on multi-colour inking and serial slicing of the specimens in a plane perpendicular to the duodenal axis...

INTRODUCTION: Ampullary adenocarcinoma (AAC) is a rare neoplasm. We sought to determine the clinicopathologic factors contributing to the overall survival (OS) and recurrence-free (RFS) survival. METHODS: Patients (pts) with resected AAC were identified from 1996 to 2015 and reviewed for clinicopathologic factors and correlated with outcome. RESULTS: We identified and evaluated 106 pts diagnosed with AAC. The median age was 70.2 years (range 41-86) and 60 (56...
