There has been no report for the expression of cyclooxygenase-2 (COX-2) and its clinicopathologic and biologic significance in ampulla of Vater cancer. This study was aimed for the clarification of COX-2 expression and its biologic roles in ampulla of Vater cancer. Fourty-six patients with ampulla of Vater cancer were enrolled and their COX-2 expression and clinicopathologic features were analyzed. The median age of patients was 60 yr and the mean duration of follow-up was 35 months (range: 14-82 months). Immunohistochemical stainings for COX-2, Ki-67, CD34 and TUNEL staining were performed. The immunoreactive COX-2 expression was present in 24 (52.2%) patients of ampulla of Vater cancer and mainly localized in cytosolic and perinuclear region. There was no significant difference in the length of survival between COX-2 postive and negative group (p=0.9420 by Log Rank test). Also, there were no significant differences of proliferation index (p=0.326), apoptotic index (p=0.764) and microvessel density (p=0.135) between COX-2 positive and negative group. Initial pTNM stage (p=0.0028 by Log Rank test) and blood transfusion over 4 pints during operation (p=0.0254 by Log Rank test) were independent prognostic factor in patients with ampulla of Vater cancer. It is suggested that immunoreactivity of COX-2 is not correlated with clinicopathologic and biologic features of ampulla of Vater cancer.

BACKGROUND/AIMS: Hedgehog protein is an essential molecule for gastrointestinal tract development, and disruption of hedgehog signaling pathway is linked to some gastrointestinal tumorigenesis. Here, we performed hedgehog immunostaining in periampullary cancer to evaluate the differences according to the location type of cancer and the differentiation of adenocarcinoma. METHODS: We retrieved surgical specimens from 43 periampullary cancer patients (15 ampulla of Vater cancer, 12 distal common bile duct cancer, 13 pancreatic head cancer, and 3 combined ampulla of Vater/bile duct cancer). Immunohistochemical stain was performed in both normal and cancerous tissue portions of each case using Sonic hedgehog (H-160) rabbit polyclonal antibody. Immunohistochemical stain results were grouped into three groups according to the percentage of positive cytoplasmic stain in tumor volume (unstained: <5%, weakly stained: 5-50%, and strongly stained: >50%). RESULTS: All of the normal tissue revealed negative immunohistochemical stain while cancerous tissue revealed positivity in 95.3% (41/43 cases). Strongly stained cases were more frequently seen in ampulla of Vater cancers (13/15) and in combined ampulla of Vater/bile duct cancers (3/3) than in distal common bile duct cancers (4/12) and in pancreatic head cancers (3/13) (p=0.002). In addition, strongly stained cases were more frequently seen in well-differentiated adenocarcinoma than the others (p<0.001). CONCLUSIONS: Most of the periampullary cancers show hedgehog protein expression. In addition, hedgehog protein immunostainings shows stronger expression in ampulla of Vater cancers and in well-differentiated adenocarcinoma.

BACKGROUND/AIMS: Epithelial-mesenchymal transition (EMT)-related proteins may exhibit differential expression in intestinal type or pancreatobiliary type ampulla of Vater carcinomas (AVCs). We evaluated the expression of E-cadherin, beta-catenin, and S100A4 in intestinal and nonintestinal type AVCs and analyzed their relationships with clinicopathological variables and survival. METHODS: A clinicopathological review of 105 patients with AVCs and immunohistochemical staining for E-cadherin, beta-catenin, and S100A4 were performed. The association between clinicopathological parameters, histological type, and expression of EMT proteins and their effects on survival were analyzed. RESULTS: Sixty-five intestinal type, 35 pancreatobiliary type, and five other types of AVCs were identified. The severity of EMT changes differed between the AVC types; membranous loss of E-cadherin and beta-catenin was observed in nonintestinal type tumors, whereas aberrant nonmembranous beta-catenin expression was observed in intestinal type tumors. EMT-related changes were more pronounced in the invasive tumor margin than in the tumor center, and these EMT-related changes were related to tumor aggressiveness. Among the clinicopathological parameters, a desmoplastic reaction was related to overall survival, and the reaction was more severe in nonintestinal type than in intestinal type AVCs. CONCLUSIONS: Dysregulation of E-cadherin, beta-cadherin, and S100A4 expression may play a role in the carcinogenesis and tumor progression of AVCs.

Angiogenesis is essential for tumor growth and metastasis. Currently, the Chalkley assay with CD34 immunostaining is the proposed standard method for angiogenesis quantification in solid tumor sections. The purpose of this study was to evaluate the expression of CD34 and its prognostic significance using the Chalkley method in node negative carcinoma of the ampulla of Vater. Between January 1997 and December 2006, 56 node negative patients who had curative resection for carcinoma of the ampulla of Vater were retrospectively reviewed. The Chalkley count was expressed as the mean value of the three counts for each tumor and further divided into two groups according to the mean value of the Chalkley count: low < 4 or high > or = 4. The mean Chalkley count value was 4.0 (+/- 3.1). In the low Chalkley group, the 1- and 3-yr recurrence rates were 18.3%, 47.6% respectively; in the high Chalkley group, the 1- and 3-yr recurrence rates were 26.5% and 60.6% respectively. Only high Chalkley count had statistical significance as a factor in recurrence of node negative ampulla of Vater carcinoma. Assessment of angiogenesis may have an important role in the prognostic evaluation of node negative cancer of the ampulla of Vater.

BACKGROUND: There have been few reports showing direct correlation between obstructive jaundice and diabetes mellitus (DM). We were able to incidentally observe the reversal of DM to normal glucose metabolism after relieving obstruction of bile duct in our patients. So, we present our cases and speculate on the pathophysiology of this phenomenon. METHODS: Four patients showed reversible DM due to obstructive jaundice from August 1993 to June 1997. We reviewed their medical records retrospectively. We ruled out other causes of glucose intolerance such as primary DM, sepsis, previous history of chronic liver disease, previous history of chronic pancreatitis, etc.. RESULTS: The first patient was a sixty-year-old male presenting obstructive jaundice due to distal blie duct cancer. The second patient was a 53-year-old female developing jaundice due to common hepatic duct stricture after laparoscopic choloecystectomy. The third patient was a 68-year old male with pancreas head cancer and glucose intolerance. The fourth patient was a 54-year-old male also developing jaundice due to common hepatic duct stricture after laparoscopic cholecystectomy. Insulin was necessary to maintain normal serum glucose level for two to three weeks postoperatively. After being relieved of jaundice, all patients showed normalized serum glucose levels. CONCLUSION: Our study suggests that obstructive jaundice itself may cause DM. So, glucose intolerance may be a useful indicator of diseases causing obstructive jaundice. However, the pathophysiology of DM with obstructive jaundice has not yet been clarified. Further studies are needed to determine the relationship.

BACKGROUND/AIMS: Ampullary adenomyoma is a benign lesion whose malignant potential has yet to be confirmed. Despite its benign nature, adenomyoma is frequently misdiagnosed as a carcinoma or adenoma and is overtreated by extensive surgery. This study was performed to analyze the clinical, pathological, and immunohistochemical features of adenomyomas in the ampulla of Vater. METHODS: Nine cases of adenomyoma in the ampulla of Vater, diagnosed in Chungbuk National University Hospital between 2008 and 2011, were enrolled in this study. We reviewed the clinical data on the symptoms, laboratory data, and radiologic findings of the abdominal computed tomography and endoscopic retrograde cholangiopancreatography. For pathological analysis, all the slides were reviewed by one pathologist, and immunohistochemical stainings with antibodies against cytokeratin 7 (CK7), cytokeratin 20 (CK20), alpha-smooth muscle actin (alpha-SMA), and Ki-67 antigen were performed. RESULTS: All the cases were CK7 positive and CK20 negative. A strong cytoplasmic expression of alpha-SMA was confirmed in all cases. The Ki-67 index was less than 1% in eight cases and 5% in one case. Four cases underwent endoscopic papillectomy, and one case received surgical ampullectomy during colorectal cancer surgery. Five cases that underwent endoscopic or surgical treatment remained symptom-free for three years. Four cases that were closely observed with repeated endoscopic examinations exhibited no interval changes in the papillary lesions. CONCLUSIONS: Endoscopic biopsy and immunohistochemistry can aid in the diagnosis of ampullary adenomyomas. Endoscopic papillectomy or surgical ampullectomy is adequate for the treatment of symptomatic ampullary adenomyomas.

We report an extremely rare case of metastatic common bile duct cancer from pulmonary adenocarcinoma presenting as obstructive jaundice. The patient was a 76-year-old male, who presented with generalized weakness and right upper quadrant pain. Plain chest X-ray noted multiple small nodules in both lung fields. Abdominal computed tomography scan showed a stricture of the mid common bile duct along with ductal wall enhancement. Endoscopic retrograde cholangiography revealed a concentric, abrupt narrowing of the mid-common bile duct suggestive of primary bile duct cancer. However, pathology comfirmed metastatic common bile duct cancer arising from pulmonary adenocarcinoma with immunohistochemical study with thyroid transcriptional factor-1 (TTF-1).

OBJECTIVETo assess the risk factors of stress-related ulcer and gastrointestinal hemorrhage after pancreaticoduodenectomy.
METHODSFrom May 1999 to July 2007, 285 periampullary cancer patients underwent pancreaticoduodenectomy in our hospital. The clinical data, pathological results, type of operation, and postoperative treatment were retrospectively analyzed. Patients with stress-related ulcer and gastrointestinal hemorrhage were selected for risk factor analysis, and other patients were taken as control group.
RESULTS35 patients (12.3%) developed stress-related ulcer and gastrointestinal hemorrhage following pancreaticoduodenectomy. Pathological examination showed pancreatic cancer in 5 cases, duodenal cancer in 8, common bile duct cancer in 10, ampullary carcinoma in 11, and solid-pseudopapillary tumors in 1. Single variate analysis demonstrated that alcohol, preoperative bilirubin level, operation time, lymph node metastasis, prealbumin decrease after operation and other complication were significantly associated with the stress-related ulcer and gastrointestinal hemorrhage. Logistic regression in multivariate analysis revealed that preoperative bilirubin level, operation time, other complication, prealbumin decrease after surgery were independent risk factors.
CONCLUSIONStress-related ulcer and gastrointestinal hemorrhage are one of the most common complications after pancreaticoduodenectomy. Preoperative bilirubin level, operation time, other complications, and prealbumin decrease after operation are four independently risk factors.
