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...

Advanced biliary tract cancers (ABTC) are among the deadliest malignancies with limited treatment options after progression on standard-of-care chemotherapy, which includes gemcitabine (GEM) and oxaliplatin (OX). The epidermal growth factor receptor inhibitor erlotinib has been explored in ABTC with modest efficacy. Erlotinib given continuously may antagonize the action of chemotherapy against cycling tumor cells, but pulsatile dosing of erlotinib with chemotherapy may improve efficacy. The purpose of this study was to assess the safety of pulsatile erlotinib with GEMOX...

Ampullary carcinoma (AC) is a rare gastrointestinal tumor without clear treatment recommendations. The management of this tumor is usually extrapolated from the treatment of pancreatic, biliary duct and intestinal cancers. Few papers have studied the AC as an independent entity and yet succombs to several limitations. These studies were retrospective single institutional experiences with limited sample sizes recruited over a long period of time. Unlike metastatic ACs where chemotherapy is the only recommended option, localized AC once excised may be approached by either chemotherapy alone or concomitant chemoradiation therapy...

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...

BACKGROUND: Most pancreatoduodenectomy resections do not meet the minimum of 12 lymph nodes recommended by the American Joint Committee on Cancer for accurate staging of periampullary malignancies. The purpose of this study was to investigate factors affecting the likelihood of adequate nodal yield in pancreatoduodenectomy specimens subject to routine pathological assessment. METHODS: Six hundred sixty-two patients subject to pancreatoduodenectomy between 1990 and 2013 for pancreatic, ampullary, and common bile duct cancers were reviewed...

BACKGROUND: Gallbladder toxicity was reported in most motesanib studies with varying frequency and at variable times after initiation of treatment. METHOD AND RESULTS: A 44-year-old man was admitted due to severe epigastric pain. The patient was diagnosed with non-small cell lung cancer 9 months ago and received 6 cycles of chemotherapy with motesanib, paclitaxel, and carboplatin. Ultrasonography showed a large amount of sludge within gallbladder. Computed tomography scan demonstrated diffuse dilatation of biliary tree with distended gallbladder without evidence of stone and mild pancreatic swelling...

Early detection of pancreatic and periampullary neoplasms is critical to improve their clinical outcome. The present authors previously demonstrated that DNA hypermethylation of adenomatous polyposis coli (APC), histamine receptor H2 (HRH2), cadherin 13 (CDH13), secreted protein acidic and cysteine rich (SPARC) and engrailed-1 (EN-1) promoters is frequently detected in pancreatic tumor cells. The aim of the present study was to assess their prevalence in pancreatic juice of carcinomas of the pancreas and periampullary area...

BACKGROUND: Expected mortality after elective pancreaticoduodenectomy (PD) in contemporary series is less than 5% in elderly patients; however, to our knowledge, mortality rate has not been correlated with indication for PD. We hypothesized that perioperative risk following PD would correlate with diagnostic indication in older patients. METHODS: The American College of Surgeons NSQIP database was reviewed to identify patients (<80 and ≥80 years) who underwent PD from January 1, 2005, through December 31, 2012...

Positive surgical margin of extrapancreatic nerve plexus (ENP) is a major cause of non-curative resection during pancreaticoduodenectomy (PD) for periampullary carcinoma (PC), which is difficult to detect at the early stage of PD. We describe a novel surgical technique using an isolating tape (iTape)-oriented ENP-first dissection (IOEFD) during PD. The iTape is firstly passed through the retroperitoneal space between ENP and inferior vena cava. Then, the iTape is further extracted from major vessels such as the common hepatic and superior mesenteric artery...

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...
