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...

Ampullary carcinoma or cancer of the ampulla of Vater is a rare malignancy with a high recurrence rate. Although cost-effective biomarkers, such as neutrophil-to-lymphocyte ratio (NLR), have been investigated in other cancers for predicting postoperative prognosis in patients, studies on the role of NLR in ampullary cancer are scarce. Here we aimed to evaluate the prognostic significance of the preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with operable ampullary carcinoma. We retrospectively reviewed 87 patients who underwent pancreaticoduodenectomy for the treatment of ampullary carcinoma between December 1999 and April 2014...

BACKGROUND: There are limited data on the efficacy of adjuvant therapy in ampullary cancer. The aim of this study was to determine whether adjuvant therapy was associated with improved survival for patients with ampullary cancer. METHODS: From the National Cancer Database, we identified ampullary cancer patients who underwent resection between 2004 and 2013. We performed 1:1 propensity score matching, comparing patients who had postoperative observation to patients who received adjuvant chemotherapy (ACT) or adjuvant chemoradiotherapy (ACRT)...

Treatment with cisplatin with gemcitabine (CG) demonstrates a survival benefit in patients with advanced biliary tract cancer (ABTC). However, the weekly administration can add significant toxicities that may prohibit prolonged treatment. Based on previous studies, we implemented a modified biweekly regimen of GC in an attempt to optimize the prescribed regimen with an improved toxicity profile, added convenience to patients while maintaining efficacy. Patients with ABTC were treated with fixed dose rate (FDR) gemcitabine (1000mg/m(2) /min) and cisplatin 20mg/m(2) on days 1 and 15 of every 28-day cycle...

Early superficial non-ampullary duodenal tumors are particularly rare, the clinical manifestations, including typical endoscopic or imaging features, and treatment methods are not well-characterized. The present case report describes a case of an asymptomatic 74-year-old male who presented to the Taizhou People's Hospital (Taizhou, China) for a regular health screening, where a primary superficial non-ampullary duodenal tumor was identified. Upper endoscopy revealed ~1.2 cm lesion in the second portion of the duodenum...

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...

Breast cancer is the most common tumor in women and the first cause of death for malignancy in the female. Bile ducts are not among the common sites of metastasis from breast cancer. Few cases of obstructive jaundice due to metastatic breast cancer have been described in the literature and they mostly resulted from widespread liver metastases that eventually involved the bile ducts. We report an exceptional case of ampullary metastasis in the absence of liver metastases. Sporadic reports have been published about the involvement of the ampulla by breast cancer metastasis...

BACKGROUND: The HMGA2 protein has experimentally been linked to EMT and cancer stemness. Recent studies imply that tumour-stroma interactions regulate these features and thereby contribute to tumour aggressiveness. METHODS: We analysed 253 cases of pancreatic ductal adenocarcinoma (PDAC) and 155 cases of ampullary adenocarcinoma (AAC) for HMGA2 expression by IHC. The data were correlated with stroma abundance and supplemented by experimental studies. RESULTS: HMGA2 acts as an independent prognostic marker associated with a significantly shorter overall survival in both tumour types...
