Abstract
BACKGROUND A rare case of neuroendocrine cell tumor (NET) having both conventional and mucinous components was reported. Mucinous NET is rarely encountered in the pathological diagnosis of gastrointestinal (GI) tumors. Here we examined the mechanism for transformation of conventional NETs into mucinous NETs. CASE PRESENTATION Macroscopic examination revealed a tumor with ulceration in the ampulla of Vater that measured 1.7 cm in its largest diameter. Histologically, the tumor comprised two components: a tubular/ribbon-like feature and small nests floating in a mucinous lake. The tumor nests showed sheet, nest and ribbon-like structures of small cells having eosinophilic cytoplasm as well as small-sized nuclei with dense hyperchromatin. Immunohistochemical analysis showed tumor cells positive for pan-endocrine markers (synaptophysin, CD56, INSM1 and chromogranin). Based on the histological findings, the solid and mucinous components were diagnosed as conventional and mucinous NETs, respectively. Grading was NET G2 based on 12.8% and 13.2% Ki-67-positive cells in the solid and mucinous components, respectively. Immunohistochemically, the mucin phenotype of this tumor was gastric and intestinal. Only the mucinous NET component had cytoplasmic CD10 expression. Examination using a customized gene panel detected only a DPC4 mutation, which was limited to the mucinous component. CONCLUSIONS Coexistence of conventional and mucinous NETs could provide important insight into evaluating the NET subtype histogenesis. Moreover, molecular alterations including cytoplasmic expression of CD10 and the DPC4 mutation can contribute to interpretation of tumor pathogenesis.

Abstract
Ampullary adenoma is a common indication for endoscopic papillectomy. Ampullary neuroendocrine tumor (NET) is a rare disease for which complete surgical resection is the treatment of choice. However, because of the morbidity and mortality associated with surgical resection, endoscopic papillectomy is increasingly used in selected cases of low grade, with no metastasis and no invasion of the pancreatic or bile duct. Also, confirmed and complete endoscopic resection of ampullary NET accompanied by adenoma has not been reported to date. We report herein a rare case of an ampullary NET accompanied with adenoma, which was successfully and completely resected via endoscopic papillectomy. Prior to papillectomy, this case was diagnosed as an ampullary adenoma.

Abstract
Intraductal papillary neoplasm of the bile duct (IPNB) exists in a pathway of multistep-carcinogenesis toward cholangiocarcinoma. Four subtypes are observed in IPNB, pancreatobiliary type, intestinal type, gastric type, and oncocytic type, similarly to the corresponding disease in the pancreas, intraductal papillary mucinous neoplasm (IPMN). IPNB can present with or without macroscopically visible mucin secretion. IPNB usually progresses to tubular adenocarcinoma. However, there are a limited number of well-described cases of gastric-type IPNB progressing not to tubular adenocarcinoma but to colloid carcinoma. Herein, we present a case of an 82-year-old female patient with gastric-type IPNB in the intrapancreatic common bile duct without macroscopically visible mucin secretion, which progressed to colloid carcinoma. As IPNB, especially without visible mucin secretion, is considered to be a heterogeneous group of diseases, such an unexpected association could occur.

Abstract
Mixed adenoneuroendocrine carcinoma (MANEC) is a malignant tumor with adenocarcinoma and neuroendocrine components, with ≥ 30% of each component required. MANEC of the ampulla is rare. To the best of our knowledge, only 15 cases of MANEC of the ampulla have been reported in the English-language literature. Here, we report two cases of MANEC of the ampulla in two women aged 43 and 60 years, which was confirmed by histology after pancreaticoduodenectomy. These tumors contained neuroendocrine and adenocarcinoma components. The neuroendocrine components were positive for chromogranin A (CgA), synaptophysin (Syn) and CD56 by immunostaining. The adenocarcinoma components were negative for CgA, Syn and CD56. Both cases were T3N0M0 (Stage IIIA). They survived for 15 and 20 mo after surgery, respectively. A brief discussion about the histopathological features, clinical behavior and treatment of MANEC of ampulla, and review of the relevant literature are presented.

Abstract
Large cell neuroendocrine carcinoma (LCNEC) in the biliary system is a poorly differentiated, high-grade neuroendocrine tumor. These tumors exhibit aggressive behavior and an increased tendency for early nodal and distant metastases. Herein, we report an unusual case of a pure primary LCNEC of the common bile duct (CBD). A 75-year-old female presented with nausea and jaundice. The patient underwent a CBD excision with lymph node dissection. Upon histological and immunohistochemical examination, the tumor exhibited pure large cell-type neuroendocrine features. Metastases were noted in two of the eight lymph nodes. The patient was administered adjuvant chemotherapy. The patient’s cancer recurred 7 mo after surgery, and the patient died from liver failure 5 mo after recurrence. The prognosis of LCNEC of CBD remains poor despite curative resection and adjuvant chemotherapy. The role of additional therapies, such as multimodal treatment including radiation therapy, must be further studied to improve the prognoses of patients.

Abstract
Intraductal papillary mucinous neoplasm of the bile duct (IPNB) is recognized as a precancerous lesion; however, both its pathogenesis and progression remain unclear. We present here a case of IPNB arising from the gallbladder accompanied by bile duct tumor thrombus in a 79-year-old female. The resected specimen revealed a tubulopapillary adenoma with no malignant cells. This case suggests that even in the absence of malignant cells, these tumors can behave as malignant tumors requiring aggressive treatment. Even if no malignant cells are present, intraepithelial neoplasms occurring in the ampullopancreatobiliary tract can behave as malignant tumors.

Abstract
Gastrointestinal stromal tumors (GISTs) usually develop in the stomach and small intestine and only rarely occur at the ampulla of Vater, with only 11 cases reported in the literature. We report a case of a GIST of the ampulla of Vater. A 36-year-old, previously healthy man presented with a loss of consciousness lasting a few minutes. A gastroduodenal endoscopy revealed a submucosal tumor with central ulceration at the ampulla of Vater. The enhanced computed tomography scan revealed a smooth-outlined hypervascular solid mass (24 mm × 30 mm) in the second part of the duodenum. Neither lymphadenopathy nor metastasis was observed. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed normal bile and pancreatic ducts. Biopsies were collected from the ulcerative lesion, and the tumor was diagnosed as a GIST. A submucosal tumor with central ulceration may be a characteristic form of GISTs of the ampulla of Vater, and biopsy studies are useful for the diagnosing such tumors. The patient underwent pancreatoduodenectomy, and the operative specimen revealed a 2.2-cm GIST with 1 mitosis per 50 high-power fields. The gold standard for treatment of GISTs is surgical resection without rupture of a capsule. If technically possible, local resection may be considered. However, when the location of the lesion presents challenges, a pancreatoduodenectomy should be performed for GIST of the ampulla of Vater.

Abstract
Mesenchymal tumors of the gastrointestinal system with variable histopathological appearances and constant expression of CD117 are known as gastrointestinal stromal tumors (GISTs). Neuroendocrine tumors may be seen in the gastrointestinal system and other organ systems of the body. We report a 44-year-old male patient with a 6.5 x 3 x 6cm mass located in the Ampulla of Vater. Histopathologic examination revealed a GIST with a marked nuclear pleomorphism and a high mitotic rate, and that was rich in osteoclast-like giant cells (OGC). Immunohistochemically, GIST was positive for CD117, while OGCs were negative for CD117 and positive for CD68 and alpha1-antitrypsin. There was also found a well-differentiated neuroendocrine tumor near the GIST, in the serosal aspect of the duodenum at the point of the Ampulla of Vater. This second tumor was 20mm in diameter, and was relatively well circumscribed with few glands invading the GIST. This tumor was positive for synaptophysin and chromogranin. Neither mitosis nor vascular invasion was observed. The patient had no familial history or clinical manifestations of neurofibromatosis. This case presents the unique synchronous existence of two extremely rare entities, a GIST with OGC and a well-differentiated neuroendocrine tumor, both located in the Ampulla of Vater.

Abstract
We report on a 61-year-old Japanese male with a pedunculated tumor in the common bile duct. The tumor consisted of two types of neoplastic cells. The majority showed atypical spindle- and giant-shaped features and proliferated densely in an inflammatory stroma, revealing a sarcomatous pattern. They expressed vimentin, KL-1, and CAM5.2. The remaining minority showed glandular and tubular features, occupied only less than 5%, located only in the tumor surface, and expressed wide spectrum keratin, KL-1, CAM5.2, epithelial membrane antigen, AE1/AE3, and carcinoembryonic antigen. CD68-positive osteoclast-like giant cells were also observed. Therefore, the patient was diagnosed as having an undifferentiated carcinoma, spindle and giant cell type.

Abstract
BACKGROUND Osteonectin has been suggested to be important in the progression of pancreatic cancer but has not been correlated with survival. We determined the osteonectin expression and its influence on survival in patients with ampullary carcinoma. METHODS Tissue microarrays were constructed from the tumors of 56 patients with ampullary cancer undergoing pancreaticoduodenectomy. Immunohistochemical staining for osteonectin was undertaken and compared with staining in chronic pancreatitis (n = 13) and normal pancreas (n = 19). Survival curves were created by the Kaplan-Meier method and compared by log rank analysis. Median follow-up for all living patients with ampullary cancer was 69.6 months. RESULTS Osteonectin was significantly (P < .05, Fisher's exact test) overexpressed in the stroma of ampullary cancers (90%) relative to chronic pancreatitis (62%) and normal pancreas (0%). Tumors expressing osteonectin were more likely to have nodal metastases than those lacking osteonectin expression (48% vs. 0%, P = .06, Fisher's exact test) and showed decreased survival. Node-negative status, pylorus preservation at the time of pancreaticoduodenectomy, and lack of osteonectin expression were predictors of prolonged survival by multivariate analysis. CONCLUSIONS Although the importance of tumor-stroma interactions in periampullary cancers is not fully understood, our data suggest that osteonectin is an integral stromal element in ampullary cancers, and its overexpression is associated with decreased survival.

Abstract
The ampulla of Vater is of high clinical relevance with regard to influx of chyme, ascending inflammation, intubation during diagnostic and therapeutic endoscopic investigation, therapeutic papillotomy, and especially to malignant transformation. Little is known about the distribution of mucins in the ampulla. In this study, we have investigated the mucin distribution in the normal ampulla of Vater and compared it to duodenal mucosa and Brunner glands. Expression of mucins in the ampulla of Vater and duodenum was monitored by reverse transcription-polymerase chain reaction and localization of the products by immunohistochemistry. The samples investigated originated from 30 autopsy cases. Mucins MUC1, MUC3, MUC4, MUC5AC, MUC5B, MUC6, MUC7, and MUC8 were expressed in the ampulla of Vater. Immunohistochemistry revealed production of MUC4, MUC5AC, MUC5B, and MUC6. The mucin composition varied in comparison with the duodenum referring to MUC2, MUC7, and MUC8. Detected mucins contribute to innate immunity, epithelial restitution, and protection against the aggressive secretions of the liver, gall bladder, and pancreas. By cross-linking, they influence the rheological properties of the secretions in the ampulla and facilitate unidirectional flow into the duodenum. Knowledge of their pattern of expression has prognostic value with regard to the detection of malignancy. The observed differences in the mucin distribution between the duodenum and the ampulla of Vater support the use of MUC2, MUC7, and MUC8 as useful tool in the classification of ampullary carcinomas.

Abstract
We describe the clinical and pathologic features of 14 cases of high-grade neuroendocrine carcinoma (HGNEC) of the ampulla of Vater classified according to WHO classification of lung tumors into small cell carcinoma (SCC, 6 cases) and large cell neuroendocrine carcinoma (LCNEC, 8 cases) types. The immunohistochemical findings were compared with those of 13 cases of primary poorly differentiated ampullary adenocarcinomas (PDACA) lacking neuroendocrine morphology. The mean age of 10 males and 4 females was 70 years. The mean tumor size was 2.5 cm. Ten of 13 patients had lymph node metastases (mean, 2.3 nodes involved). Documented sites of distant metastases included brain and liver. Overall, 64% of patients with ampullary HGNEC died of disease (mean follow-up, 14.5 months). Four patients had no evidence of disease after resection (mean, 20 months). Half of the tumors were associated with adenomas of the adjacent mucosa, 2 with high-grade dysplasia. Two HGNECs were combined with a conventional adenocarcinoma and another with a squamous cell carcinoma component. By immunohistochemistry, the HGNECs were positive for cytokeratins (AE1/AE3, 100%; Cam5.2, 67%; CK7, 87%; CK20, 38%), similar to the pattern found in PDACAs. p27 expression was lost in 1 case of HGNEC and in all PDACAs. Retinoblastoma (Rb) protein expression was lost in 60% of HGNECs and in none of the PDACA cases. In conclusion, HGNECs of the ampulla are rare (2%-3% of ampullary tumors in our material). The clinical course parallels that of their pulmonary counterparts and appears to be worse than that of locally advanced ampullary adenocarcinomas. The association with adenoma and or conventional adenocarcinoma components may suggest a common pathway in the initial carcinogenesis of these two types of tumors. Loss of Rb expression, a characteristic finding in pulmonary SCCs, is present in almost half of ampullary HGNECs. In contrast, p27 expression is lost in PDACAs and retained in most HGNECs. Thus, there are differences in the molecular phenotypes of these two types of ampullary carcinoma, supporting the distinction of poorly differentiated carcinomas with a neuroendocrine phenotype from those without.

Abstract
BACKGROUND There is a lack of data in the literature concerning the identification of potential prognostic factors in ampullary adenocarcinoma. AIMS To examine the prognostic significance of Bax, Bcl-2, and p53 protein expression and the apoptotic index in a large cohort of uniformly treated patients with radically resected ampullary cancer. METHODS All patients with a pathological diagnosis of ampullary cancer and radical resection were evaluated. Expression analysis for p53, Bax, and Bcl-2 was performed by immunohistochemistry. Apoptotic cells were identified by terminal deoxynucleotidyl transferase mediated dUTP nick end labelling (TUNEL). RESULTS Thirty nine tumour specimens from patients with radically resected ampullary adenocarcinoma were studied. A positive significant correlation between Bax and p53 expression was found by rank correlation matrix (p < 0.001). A trend towards a positive correlation was found between the apoptotic index and p53 expression (p = 0.059). By univariate analysis, overall survival was influenced by Bax expression, p53 expression, and TUNEL staining (p = 0.001, p = 0.01, and p = 0.03, respectively). Bcl-2 expression did not influence overall survival in these patients (p = 0.55). By multivariate Cox regression analysis, the only immunohistochemical parameter that influenced overall survival was Bax expression (p = 0.020). CONCLUSIONS These results provide evidence that apoptosis may be an important prognostic factor in patients with radically resected ampullary cancer. This study is the first to assess the clinical usefulness of Bax expression in radically resected ampullary cancer.

Abstract
A granular cell tumor (GCT) in a 39-year-old white man is reported. It was localized in the intrapancreatic part of the common bile duct and caused obstruction of the bile downflow. The patient underwent radical surgical procedures because a malignant tumor was clinically suspected. Macroscopically, the tumor appeared as a duct stricture caused by diffuse infiltration of neoplastic cells in the walls. In the cytoplasm smaller and larger PAS-positive granules were present and constantly reactive to S-100 and NSE antibodies. Ultrastructurally, cytoplasmic granules appeared as membrane-bound vacuoles of variable size and shape containing debris, disrupted mitochondria, and myelin figures. No basal lamina around cell cytoplasm was observed. GCTs are relatively uncommon soft tissue tumors usually presenting in the skin and subcutaneous tissues or tongue. The prognosis in any location is quite good, but very rare malignant GCTs (1-2%) are documented. Complete excision reduces the risk of recurrence. Accurate operative diagnosis seems to be critical when the tumors are located in the intrapancreatic common bile duct as in this reported case. Gastro-pancreatico-duodenectomy is too radical a procedure for such a benign lesion and additional assessments and investigations are recommanded before such an extensive radical surgery.

Abstract
AIMS Several studies have reported that dysregulation of beta catenin or k-ras mutation promotes cyclin D1 expression. This study investigated the relation between cyclin D1 expression and clinicopathological parameters in carcinoma of the ampulla of Vater (CAV), and also assessed the relation between increased cyclin D1 expression and beta catenin/k-ras status in this series. METHODS Thirty CAVs were evaluated for cyclin D1 expression by immunohistochemistry in relation to patient clinicopathological features. Aberrant beta catenin expression and k-ras mutation were also investigated by immunostaining and direct sequencing, and related to cyclin D1 expression. RESULTS Increased cyclin D1 expression was seen in 17 of 30 CAVs and was significantly correlated with tumour cell proliferation and disease free survival time (p = 0.018, p = 0.018, respectively). Nuclear accumulation of beta catenin was found in nine of 30 cases, including four cases with missense mutations in exon 3 of CTNNB-1, and was significantly correlated with increased cyclin D1 expression (p = 0.003). k-ras gene mutation was detected in 12 of 30 cases, and was also significantly correlated with increased cyclin D1 expression (p = 0.026). Overall, 14 of 17 CAVs with increased cyclin D1 expression showed nuclear accumulation of beta catenin and/or k-ras mutation. CONCLUSIONS Increased cyclin D1 expression appears to be associated with tumour proliferation and poorer clinical outcome in CAV. It is also associated with both aberrant beta catenin expression and k-ras mutation. These results are consistent with the in vitro data that cyclin D1 can be transactivated by activated beta catenin-T cell factor/LEF and k-ras pathways.

Abstract
Abstract
We describe a Paneth cell carcinoma arising within the ampulla of Vater in a 64-year-old man. The phenotype of virtually all neoplastic cells was consistent with that of Paneth cells, based on routine morphology and their strong positive immunostaining for lysozyme. Additional widespread positive immunostaining for carcinoembryonic antigen and CA 19.9 supports a totipotential cell as the origin of such neoplastic cells. This case, therefore, represents a true Paneth cell carcinoma, as opposed to inclusion of occasional neoplastic Paneth cells into a poorly differentiated adenocarcinoma. This pattern of differentiation is rare, and predictions regarding its ultimate biological behavior and malignant potential must be guarded.

Abstract
We present herein a rare case where cancer of the Vater's ampulla was complicated with pancreas divisum. Endoscopic retrograde cholangiopancreatography demonstrated the pancreas divisum and stenosis of the common channel due to the tumorous lesion of the Vater's ampulla. Magnetic resonance cholangiopancreatography demonstrated that the Wirsung duct and Santorini duct were unconnected. The biopsy specimen at the upper gastrointestinal endoscopy revealed moderately differentiated tubular adenocarcinoma. The patient was diagnosed with cancer of the Vater's ampulla complicated with pancreas divisum, and underwent a pylorus-preserving pancreaticoduodenectomy. Immunohistochemical examination showed that the p53 protein and the alpha5beta1-integrin were expressed in tumour cells, and the proliferating cell nuclear antigen test was positive. Furthermore, the alpha5beta1-integrin was expressed in chronic pancreatitis tissue. We demonstrate that there is a risk that pancreas divisum will co-exist with malignant disease in the pancreaticobiliary area, causing a potential risk of complicating malignant diseases in the pancreas.

Abstract
Several Helicobacter species have recently been isolated from the bile and hepatobiliary systems of murine species, and are well recognized as a pathogen of the hepatobiliary disorder. This study was planned to investigate whether Helicobacter species possess a causative potential for human hepatobiliary disease, especially for hepatobiliary carcinogenesis. Bile and hepatobiliary tissue samples from 19 patients with hepatobiliary cancer and 19 patients with benign biliary diseases were subjected to polymerase chain reaction analyses for the detection of Helicobacter DNAs. Using a proliferating cell nuclear antigen (PCNA) staining technique, we also investigated the biliary epithelial cell kinetics with special reference to the presence of Helicobacter DNAs in the hepatobiliary system. We found that Helicobacter DNAs were positive in 10 (52.6%) of the 19 patients with hepatobiliary cancer. The incidence was significantly higher than that (15.7%) in the benign cases (P = 0.03). The PCNA labeling index in the biliary epithelium in Helicobacter DNA-positive patients was statistically higher than that in Helicobacter DNA-negative ones, regardless of whether the patient was suffering from hepatobiliary cancer and/or biliary inflammation. A close correlation between the presence of Helicobacter DNAs and an elevation of the PCNA labeling index in the biliary epithelium was demonstrated by multiple regression analysis. Our findings suggest that Helicobacter species may play a role in the pathogenesis of hepatobiliary cancer through an acceleration of biliary cell kinetics.

Abstract
BACKGROUND Duodenal somatostatinoma is a rare neuroendocrine neoplasm. A better prognosis can be obtained if these tumors are resected at an early clinical stage. Endoscopic punch biopsy has been the method most commonly used for the preoperative diagnosis of neuroendocrine duodenal tumors. To the best of our knowledge, endoscopic fine needle aspiration biopsy (FNAB) of duodenal somatostatinoma has not been reported before. CASE A 41-year-old, black female presented with upper gastrointestinal bleeding as well as elevated bilirubin, liver enzymes and glucose. Computed tomography, esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP) detected a mass at the region of the ampulla of Vater partially obstructing the pancreatic duct. The initial punch biopsy yielded only intestinal mucosa. Subsequent endoscopic FNAB suggested the diagnosis of a neuroendocrine neoplasm, as confirmed by additional punch biopsies. Immunohistochemical and electron microscopic studies disclosed somatostatin production by the tumor, which was resected through a modified Whipple procedure. The patient recovered fully. CONCLUSION This case demonstrates the usefulness of endoscopic FNAB in diagnosing submucosal gastrointestinal neuroendocrine tumors.

Abstract
Adenoma and adenocarcinoma of the ampulla of Vater are uncommon neoplasms of the gastrointestinal tract. Only one report has analyzed the relationship between ampullary adenocarcinoma and pancreatic intraductal neoplasia (PanIN), the precursor lesion of pancreatic adenocarcinoma. An association between PanIN and ampullary adenoma has not been reported previously. Case reports have documented the progression of PanIN to invasive pancreatic adenocarcinoma. We reviewed five resected ampullary adenoma and 17 ampullary adenocarcinoma cases and evaluated the pancreas for PanIN. Pancreatic sections from 35 autopsies were reviewed as a control group. Immunohistochemistry for overexpression of p53 and COX-2 proteins was performed in selected cases, as was PCR analysis for K-ras mutations. Follow-up clinical data were obtained. All 22 ampullary neoplasms were associated with PanIN, which was high grade in two (40%) adenoma cases and seven (41%) adenocarcinoma cases. In 16 (73%) evaluable cases, PanIN extended to the pancreatic resection margin; two of which had high grade PanIN. Among the autopsy controls eight (23%) had low-grade PanIN. Seven of the 22 ampullary cases but none of the autopsy controls had coexistent pancreatitis. A smoking history was present in two of four autopsy cases in which this history was available. Overexpression of the p53 and COX-2 proteins was present in only one case of high-grade PanIN. K-ras mutations were present in four of four of the PanIN lesions evaluated, including one autopsy case. Clinical follow-up revealed no progression of PanIN to invasive carcinoma in the remnant pancreas, although the follow-up period was too short to adequately assess that risk (an average of 3.8 y for adenoma cases and 2.5 y for adenocarcinoma cases). We conclude that adenomas and carcinomas of the ampulla are associated with PanIN, and often high-grade PanIN. Although its malignant potential has not been fully established, PanIN is underreported and often unrecognized. PanIN may be analogous to colorectal adenoma in that both are prevalent in the older adult population, but few progress to carcinoma.

Abstract
The aim of the study was to examine the relation between p53 protein accumulation, clinicopathological variables and prognosis in resectable adenocarcinomas of the pancreatic head. The clinical records and tissue specimens of 82 consecutive patients resected for adenocarcinomas located in the head of the pancreas were reviewed retrospectively. Formalin-fixed and paraffin-embedded specimens from each tumour were stained with the monoclonal antibody DO7, and the nuclear p53 positivity within each tumour was assessed. Histopathological reclassification showed that 60 tumours exhibited ductal differentiation and 22 tumours intestinal differentiation. Twenty-five percent (15/60) of the ductal tumours and 50% (11/22) of the intestinal tumours were positive for p53 accumulation. p53 immunoreactivity was significantly correlated to a worse prognosis in the tumours of ductal differentiation, with median survival 0.76 years for p53 positive and 1.44 years for p53 negative patients. The p53 positivity of tumours with intestinal differentiation showed no such correlation. No correlation was found between p53 accumulation and other known prognostic factors in either the ductal or the intestinal type of tumours. Our results indicate that the tumour biology of ductal adenocarcinomas differs significantly from that of adenocarcinomas of the intestinal type located in the pancreatic head, and that p53 accumulation confers a worse prognosis only of ductal tumours. Subclassification of these tumours based on type of differentiation is therefore suggested since periampullary tumours include ductally as well as intestinally differentiated adenocarcinomas.

Abstract
Fas and Fas ligand expression were immunohistochemically investigated in 34 extrahepatic bile duct carcinomas (BDC) and nine ampulla carcinomas (AC). Fas expression was regarded as positive in 22 BDC cases (64.7%). The absence or decreased expression of Fas was frequently observed in cases with high biological aggressiveness such as advanced stage, moderate or poor differentiation, lymph node metastasis, aberrant p53 expression and high Ki-67 labeling index. A similar tendency was observed in AC where two cases without Fas expression were poorly differentiated with a high Ki-67 labeling index. Fas ligand expression in infiltrating mononuclear cells adjacent to the carcinoma nests was observed in only four BDC (11.1%) and in none of the AC examined. Fas ligand expression in carcinoma cells was observed in only one BDC, which showed Fas ligand expression also in mononuclear cells and not in any AC case. These results suggest that, although BDC and AC very frequently express Fas, Fas-mediated apoptosis is only occasionally induced in carcinoma cells because of the lack of Fas ligand expression in infiltrating mononuclear cells in these carcinomas.

Abstract
Human spasmolytic polypeptide (hSP) is a member of the trefoil peptide group, thought to be involved in mucin production and cell growth. It has been reported that hSP protein is expressed in digestive cancers but not in normal pancreas. The expression of hSP in pancreatic neoplasms has not been investigated in detail. The immunohistochemical expression of hSP protein was investigated in pancreatic carcinomas, ampullary carcinomas, mucin-producing tumors, serous cystadenomas and islet cell tumors of the pancreas. hSP was expressed in 23% of pancreatic duct cell carcinomas, and hSP protein was more frequently detected in cases of early-stage or histologically low-grade duct cell carcinomas than in cases of late-stage or histologically high-grade carcinomas. Patients with hSP protein expression showed a better prognosis than did those with negative hSP expression. hSP expression was detected in 92% of mucin-producing tumors, but was not detected in serous cystadenoma or islet cell tumors. Immunohistochemical hSP expression is related to differentiation and a better prognosis in pancreatic duct cell carcinomas. Furthermore, hSP protein is related to the pathogenesis and clinical characteristics of mucin-producing tumors of the pancreas.

Abstract
ets-1 is a transcription factor known to induce the expression of various genes important for carcinoma progression. However, its clinical significance does not seem to be uniform for all carcinomas. In this study, we investigated the ets-1 expression in 41 extrahepatic bile duct carcinomas (BDC) and 19 cholangiocellular carcinomas (CCC). Epithelial cells of normal ducts only occasionally expressed ets-1, whereas cells of reactive ducts and dysplastic ducts were often positive for this protein. On the other hand, 61.0% of BDC and 21.6% of CCC were classified as ets-1-positive, because more than 5% of the carcinoma cells expressed ets-1. The expression of ets-1 showed inverse relationships with the Ki-67-labeling index and vascular and perineural invasion of BDC, whereas no such relationships could be established in CCC. Furthermore, the well-differentiated BCD more frequently expressed ets-1. These results suggest that ets-1 works as a transcription factor in malignant transformation and progression in early phases of BDC.

Abstract
The expression of thymidine phosphorylase (TP) in carcinoma of the papilla of Vater was studied to clarify its significance in tumor progression and in determining prognosis. Fifty-nine cases of surgically resected carcinoma of the papilla of Vater were studied. Immunohistochemical staining was performed to evaluate the expression of TP, microvessel count and p53 overexpression. TP expression was demonstrated in tumor cells in 62.7% (37/59) of the cases. A higher frequency of regional lymph node metastasis was found in TP-positive tumors than in TP-negative tumors (P = 0.006). TP-positive tumors were more advanced than TP-negative tumors with regard to clinical stage (P = 0.035). TP-positive tumors had significantly higher microvessel density (27.6 +/- 10.1) than TP-negative tumors (20.4 +/- 10.0, P = 0.01). Moreover, TP expression was significantly correlated with a poor prognosis (P = 0. 02). These suggest that in carcinoma of the papilla of Vater, TP production by tumor cells is correlated with tumor progression through its regulatory effect on neovascularization.

Abstract
Primary malignant melanoma of the common bile duct is rare. To our knowledge, only 6 cases have been reported previously. The pathologic diagnosis of primary malignant melanoma in extracutaneous sites often requires the use of confirmatory immunohistochemical stains and electron microscopy studies, as well as tests to rule out other possible remote or concurrent primary sites. The presence of junctional activity adjacent to the tumor is another important requisite for the diagnosis of this entity. Nevertheless, absolute exclusion of a metastatic melanoma from an unknown occult site or regressed site is not entirely possible. We describe our observations in a case of primary malignant melanoma of the common bile duct in a 48-year-old man and discuss the criteria for diagnosis of primary melanoma.

Abstract
Carcinosarcoma of the duodenum has not been reported previously, although this type of tumor has been detected in other organs. We present here a case of carcinosarcoma of the duodenum, including immunohistochemical and electron microscopical findings. An ulcerating tumor, located in the duodenal ampullary region, contained two divergent components: ordinary differentiated tubular adenocarcinoma, and sarcomatoid tissue composed of spindle tumor cells. Immunohistochemically, the adenocarcinoma cells were stained with antibodies against epithelial markers including keratin and CA19-9. In contrast, the sarcomatoid tissue was strongly positive for vimentin and was focally positive for myoglobin, keratin, and CA19-9. We speculate that the sarcomatoid element of the carcinosarcoma arose from part of the ordinary adenocarcinoma tissue.

Abstract
OBJECTIVE To evaluate the prognostic value of the proliferative factors, MIB-1 index, DNA ploidy, and S-phase fraction, and further to determine the independent prognostic factors in ampulla of Vater carcinoma after pancreaticoduodenectomy. SUMMARY BACKGROUND DATA Cell kinetics are important indicators of the biologic behavior of various human tumors, but only a few authors have reported the application of cell proliferative factors in ampulla of Vater carcinoma. METHODS Patients undergoing pancreaticoduodenectomy for ampulla of Vater carcinoma were included. Proliferative factors, MIB-1 index, and DNA contents, measured by flow cytometry, were evaluated and compared with the conventional clinicopathologic factors. RESULTS Ninety resectable ampulla of Vater carcinomas were included. By univariate analysis, MIB-1 index, DNA ploidy, S-phase fraction, stage, and lymph node status were significant prognostic factors. The 5-year survival rate was 40.7% for tumors with MIB-1 index < or =15% and 0% for those with MIB-1 index >15%. Diploid tumors had a significantly better prognosis than aneuploid. Outcomes of stage I and II tumors were more favorable than those of stage III and IV. After multivariate analysis, MIB-1 index, DNA ploidy, and stage remained as the independent prognostic factors. Among the three independent prognostic factors, MIB-1 index was the most powerful. CONCLUSIONS Both MIB-1 index and DNA ploidy provide important prognostic value and potentially complement the conventional prognostic factors in resectable ampulla of Vater carcinoma. MIB-1 index is the most powerful independent prognostic factor.

Abstract
BACKGROUND Although ampullary carcinoid tumors (ACs) are often categorized clinically as duodenal carcinoid tumors (DCs), there are distinct clinical and pathologic differences. METHODS Clinical, histopathologic, and immunohistochemical features of 12 ACs were compared with those of 53 DCs that did not involve the ampulla. RESULTS Patients with AC were ages 28-74 years (mean, 54.9 years); 8 were males and 4 were females. Five were white and three were black; the race of four patients was not known. The size of ACs ranged from 0.2 to 5.0 cm in greatest dimension. There were no significant differences between AC patients and DC patients with respect to male predominance, race, tumor size, and mitotic rate. The insular growth pattern was more common in AC; the cribriform type was more common in DC. Four of 12 ACs contained psammoma bodies, versus none of 53 DCs (P = 0.001). The rate of metastasis was similar in patients with AC (4 of 12, 33%) compared with DC patients (14 of 53, 26%). In DC patients, involvement of the muscularis propria, a size greater than 2 cm, and mitotic activity were significantly correlated with metastatic risk. In AC patients, tumor size and mitotic activity had no correlation with metastatic potential. One AC had features of an atypical carcinoid tumor; there were none in the duodenal group. One-half of patients with AC presented with jaundice versus 7% of patients with DC (P = 0.005). Three patients (25%) with AC had von Recklinghausen disease versus 0 of 53 patients with DC (P = 0.003). Immunohistochemically, tumor cells expressed somatostatin in 67%, serotonin and cholecystokinin in 17%, insulin in 25%, and glucagon and gastrin in 0% of ACs. In contrast, 56% of DCs expressed gastrin (P < 0.001). CONCLUSIONS Carcinoid tumors of the ampulla differ clinically, histologically, and immunohistochemically from carcinoid tumors elsewhere in the duodenum.

Abstract
BACKGROUND Some adjuvant or neoadjuvant therapy could be important for patients operated on for tumours of the ampulla of Vater, especially for those having a higher risk of recurrence. AIM To evaluate prognostic factors after curative surgery based on a series of 45 cases of malignant tumours of the Oddi sphincter. PATIENTS From 1970 to 1992, a curative resection was performed in 45 patients (age 62.8 (SD 10.1) years) with adenocarcinoma of the ampulla. Surgical procedures included pancreatoduodenectomy (n = 42) and resection of the ampulla (n = 3). Actuarial survival was 44 (SD 9)% at five years. METHODS Various prognostic variables were studied: clinical manifestations, macroscopic aspect, differentiation, noninvasive adenomatous component, mucin histochemistry, immunohistochemistry (CEA, CA19.9, p53, Ki67), and accepted classifications (Blumgart and Kennedy, Martin, Yamaguchi and Enjoji, Talbot et al, pTNM). RESULTS Variables with prognostic power, in order of importance were: Classification of Talbot et al; CA19.9; pTNM; sialomucins; classification of Yamaguchi and Ejoji; Martin classification; sulphomucins; non-invasive adenomatous component (positive > negative); jaundice; tumour localisation. CONCLUSIONS This series confirmed the prognostic power of former classifications and showed the prognostic power of other variables (mucin, non-invasive adenomatous component, CA19.9).

Abstract
OBJECTIVE To determine the possible role of Ki-67 antigen expression by visual and computed quantitation in diagnosing ampullary lesions. STUDY DESIGN Twenty-two cases of ampullary lesions treated at Thomas Jefferson University Hospital between 1989 and 1994 were analyzed. Four cases of adenoma, 4 of epithelial dysplasia in adenoma, 7 of well-differentiated adenocarcinoma and 7 of high grade adenocarcinoma were included. For each case three consecutive sections were obtained from the paraffin-embedded blocks. The first slide was stained with hematoxylin & eosin for visual diagnosis; the other two were immunoprocessed to evaluate the expression of Ki-67 antigen. Visual quantitation of Ki-67 was evaluated by light microscopy, and computed quantitation was performed utilizing the SAMBA 4000 cell image analysis system. RESULTS Immunohistochemical analysis of the ampullary lesions showed a positive correlation of Ki-67 expression, both by visual and computed quantitation, with biologic grade. The cell proliferation sequence was carcinoma, adenoma with dysplasia and adenomia. CONCLUSION Ki-67 antigen expression correlated highly with the progression of malignancy in ampullary lesions. Computed quantitation of Ki-67 was more sensitive than visual quantitation, especially in differentiating between low and high grade adenocarcinomas.

Abstract
It is now recognised that epithelial-stromal interactions are important in a wide range of disease processes including neoplasia and inflammation. Metalloproteinases are central to matrix degradation and remodelling, which are key events in tumour invasion and metastasis and may also be involved in tissue changes occurring in chronic inflammation. Immunohistochemistry was performed on sections from 50 patients with pancreatic cancer (n = 27), ampullary cancer (n = 12), low bile duct cancer (n = 3), neuroendocrine tumours (n = 3) and chronic pancreatitis (n = 5), using antibodies raised against collagenase (MMP2), stromelysin (MMP3) and tissue inhibitor of metalloproteinase (TIMP1) and developed using the avidin-biotin complex method. Abundance of MMP2, MMP3 and TIMP1 was greater in pancreatic and ampullary cancer than any other pathology and immunoreactivity in the malignant epithelial cells in pancreatic and ampullary cancer was greater than in the stromal tissues (in pancreatic cancer: MMP2 100% vs 37%, MMP3 93% vs 15%, TIMP1 93% vs 4%, P < 0.0001). There were strong correlations between the immunoreactivity of the two antibodies for MMP2 (P < 0.0001), between MMP2 and TIMP1 (P < 0.0001) and between MMP3 and TIMP1 (P < 0.0001). The immunoreactivity for TIMP1 in pancreatic and ampullary cancers with lymph node metastases was significantly less compared with those cases without lymph node metastases (P < 0.02) and there was an association between increased immunoreactivity for MMP2 and the degree of tumour differentiation (P < 0.01). The results implicate MMP2, MMP3 and TIMP1 in the invasive phenotype of pancreatic and ampullary cancer.

Abstract
Expression of the molecular biological factors (MBFs) c-erbB-2, Ki-67 antigen, and tenascin (TN) was assessed immunohistochemically in specimens from patients who had undergone surgery for carcinoma of the papilla of Vater. The MBFs were then analyzed by histological factors (v, d, panc, n, Stage), which have been demonstrated to be outcome predictors, and by patient outcome. None of the MBFs showed any significant correlation with the histological factors. There were significant differences (p < 0.05) in the expression of c-erbB-2, Ki-67 antigen, and TN between patients who survived >5 years and those who survived <5 years. The patients with greater expression of c-erbB-2, Ki-67 antigen, and TN had a poor prognosis, whereas those with less expression had a good prognosis. They were therefore considered independent predictors of outcome for carcinoma of the papilla of Vater. Combined analysis of both histological factors and MBFs was also performed, with the result that the combined analysis of MBFs yielded a better prediction of outcome in carcinoma of the papilla of Vater than analysis of either one histological factor or MBF.

Abstract
Immunohistochemical expression of the p53 protein was investigated in carcinoma of the gallbladder (n = 13), common bile duct (n = 7) and ampulla of Vater (n = 9) using the polyclonal, CM1, and monoclonal, DO7, antibodies (Novocastra). This was compared with cases of chronic cholecystitis (n = 11) and preneoplastic lesions of the gallbladder (n = 4) and ampulla (n = 3). Nuclear immunostaining for p53 protein was found only in the poorly differentiated adenocarcinomas of the gallbladder (n = 9) and were associated with a shorter patient survival period (median: 18.6 mths). The moderately differentiated adenocarcinomas (n = 4) did not show p53 immunostaining and were associated with a longer median survival period (26 mths). The gallbladder dysplasias and adenoma also had no p53 protein immunoreactivity. The common bile duct carcinomas did not stain for p53. Focal p53 immunoreactivity was present in only one (11%) of the cases of ampullary carcinoma and in one (9%) of chronic cholecystitis. In summary, increased p53 immunostaining was associated with reduced patient survival and found more frequently in poorly differentiated adenocarcinoma of the gallbladder but not in the better differentiated carcinoma, chronic cholecystitis or preneoplastic lesions of the gallbladder. The differences in p53 immunohistological expression between gallbladder, common bile duct and ampullary carcinomas justify further investigation into the molecular mechanisms responsible for their development.

Abstract
Immunohistochemical expression of the nm23-H1 protein was investigated in carcinoma of the gallbladder (n = 13), common bile duct (n = 5) and ampulla of Vater (n = 7) using the monoclonal antibody, NM 301 (Molecular Oncology Inc.). This was compared with cases of chronic cholecystitis (n = 11) and preneoplastic lesions of the gallbladder (n = 4) and ampulla (n = 3). Absent or weak nm23-H1 protein immunoreactivity was found in most (67%) of the poorly differentiated adenocarcinomas of the gallbladder and in half of the cases of moderately differentiated adenocarcinomas. The difference in nm23-H1 protein immunostaining between gallbladder carcinoma and chronic cholecystitis was statistically significant (p = 0.0022; X2 test). Significant correlation was found between prolonged patient survival periods and nm23-H1 immunoreactivity in gallbladder carcinomas (R = 0.687, p = 0.01, linear regression analysis; r = 0.652, p = 0.016, Spearman's rank test). Most of the gallbladder dysplasias and adenomas had no reduction in nm23-H1 protein immunoreactivity. All common bile duct carcinomas, most (67%) ampullary carcinomas in situ and some (43%) ampullary carcinomas had moderate to strong nm23-H1 immunostaining. In summary, low nm23-H1 protein immunoreactivity was found more frequently in gallbladder carcinomas than in chronic cholecystitis and was associated with reduced patient survival. The differences in nm23-H1 protein immunoreactivity in common bile duct and ampullary carcinomas suggest that these tumors have a different molecular origin to gallbladder cancers.

Abstract
The histopathology of 12 patients with adenoma of the ampulla of Vater was examined to trace the adenoma-carcinoma sequence of the ampulla of Vater. Immunohistochemistry for carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 was also performed. Four large adenomas with mild dysplasia also had foci of moderate dysplasia while another one contained foci of severe dysplasia (intramucosal carcinoma). Immunohistochemically, adenomas of mild to moderate dysplasia had either linear CEA and CA19-9 immunoreactants at the apical portions, or fine granular immunoreactants in the cytoplasm of adenoma cells. In addition, adenomas of severe dysplasia (intramucosal carcinoma) showed a more diffuse or dense immunoreactivity for these two substances in the cytoplasm. These results are consistent with the adenoma-carcinoma sequence for the ampulla of Vater. The immunohistochemistry for CEA and CA19-9 was representative of the degree of dysplasia in the adenoma cells, but the relationship was not conclusive.

Abstract
DNA cytofluorometric analysis of carcinoma cells of the periampullary region was performed using cytologic bile specimens. The materials were obtained from three cases of obstructive jaundice through percutaneous transhepatic biliary drainage tubes. The DNA ploidy histograms of bile samples could be evaluated as well as those of paraffin-embedded tissue samples. DNA analysis using cytologic bile specimens may reveal biological behavior of carcinoma cells and provide useful information for the choice of therapeutic interventions.

Abstract
A total of 304 patients with pancreatoduodenal carcinoma were studied clinicopathologically and immunohistochemically in order to clarify features of carcinoma of four different sites of origin; carcinoma of the ampulla of Vater (Am), the distal common bile duct (DCBD), the head of the pancreas (PH), and the extra-ampullary duodenum (Du). The mean greatest diameter of 87 PH was 3.5 cm compared with 2.7 cm of 149 Am and 2.7 cm of DCBD. Histopathologically, 40% of Am were papillary adenocarcinoma, while about half of DCBD, PH and Du were tubular adenocarcinoma. PH invaded lymphatic (85%), vascular (62%), and perineural (95%) spaces and metastasized lymph nodes (72%) more frequently than Am (77%, 35%, 24%, 50%), DCBD (47%, 61%, 65%, 45%), and Du (76%, 29%, 35%, 65%), respectively. More than 50% of PH invaded the resected margins, whereas in only 2% of Am, the surgical margins were affected by malignant cells. Immunohistochemically, PH was more frequently positive for both carcinoembryonic antigen (CEA) (98%) and carbohydrate antigen (CA) 19-9 (91%) than Am (83%, 62%), DCBD (94%, 58%), and Du (56%, 11%), respectively. The stromal staining type of CEA and CA 19-9 was more frequently seen in PH (27%, 44%) than in Am (9%, 31%), DCBD (11%, 8%) and Du (0%, 0%), showing a more dedifferentiated nature of PH. The cumulative 3-year survival rate of 87 patients with PH (15%) was worse than that of 149 with Am (42%, P less than 0.001), of 51 with DCBD (25%) and of 17 with Du (58%, P less than 0.001). The survival curve of 87 with PH was worse than that of 51 with DCBD, of 149 with Am (P less than 0.001) and of 17 with Du (P less than 0.001). Cox regression analysis, using eleven profound prognostic variables, revealed that venous invasion, perineural infiltration, surgical margin, and histopathologic type were profound prognostic factors. Pancreatic carcinoma has a more dedifferentiated histopathologic nature, showing a more aggressive growth and fares worse than Am, DCBD, and Du.

Abstract
The nuclear DNA content in 71 cases of periampullary cancer (27, cancer of the head of the pancreas (Ph); 24, cancer of the ampulla of Vater (A); and 20, cancer of the inferior common bile duct (Bi] was measured cytofluorometrically using the archival paraffin-embedded specimens of the primary lesions. They were analyzed in relation to prognosis, tumor size, histological differentiation, lymph node metastasis, lymphatic invasion, venous invasion, perineural invasion, and growth pattern. The results show that "Ph" has more unfavorable prognosis compared with the other two and it has more DNA content under the same conditions such as tumor from 2.1 to 4 cm in its greatest dimension, well differentiated adenocarcinoma, with or without lymph node metastasis, with or without venous invasion, with lymphatic invasion, with perineural invasion, and in the intermediate growth pattern between expansive and infiltrative. In conclusion, this study demonstrates a close correlation between the DNA content and prognosis and the significant clinical value of DNA analysis for predicting the prognosis in patients of periampullary cancer.
