Carcinoids of the common bile duct: a case report and literature review. (1/323)

Carcinoids of the extrahepatic bile ducts and particularly the common bile duct are extremely rare. A 65-year-old woman presented with obstructive jaundice. Laboratory and imaging studies gave results that were consistent with an obstructing lesion in the common bile duct. In this case, a stent was inserted initially to decompress the bile ducts. Subsequently a laparotomy and pancreaticoduodenectomy were performed and a tissue diagnosis of carcinoid of the common bile duct was made. The patient was well with no evidence of recurrence 17 months postoperatively. The authors believe this is the 19th reported case of an extrahepatic bile duct carcinoid.  (+info)

Reexploration for periampullary carcinoma: resectability, perioperative results, pathology, and long-term outcome. (2/323)

OBJECTIVE: This single-institution experience retrospectively reviews the outcomes of patients undergoing reexploration for periampullary carcinoma at a high-volume center. SUMMARY BACKGROUND DATA: Many patients are referred to tertiary centers with periampullary carcinoma after their tumors were deemed unresectable at previous laparotomy. In carefully selected patients, tumor resection is often possible; however, the perioperative results and long-term outcome have not been well defined. METHODS: From November 1991 through December 1997, 78 patients who underwent previous exploratory laparotomy and/or palliative surgery for suspected periampullary carcinoma underwent reexploration. The operative outcome, resectability rate, pathology, and long-term survival rate were compared with 690 concurrent patients who had not undergone previous exploratory surgery. RESULTS: Fifty-two of the 78 patients (67%) undergoing reexploration underwent successful resection by pancreaticoduodenectomy; the remaining 26 patients (34%) were deemed to have unresectable disease. Compared with the 690 patients who had not undergone recent related surgery, the patients in the reoperative group were similar with respect to gender, race, and resectability rate but were significantly younger. The distribution of periampullary cancers by site in the reoperative group undergoing pancreaticoduodenectomy (n = 52) was 60%, 19%, 15%, and 6% for pancreatic, ampullary, distal bile duct, and duodenal tumors, respectively. These figures were similar to the 65%, 14%, 16% and 5% for resectable periampullary cancers found in the primary surgery group (n = 460). Intraoperative blood loss and transfusion requirements did not differ between the two groups. However, the mean operative time was 7.4 hours in the reoperative group, significantly longer than in the control group. On pathologic examination, reoperative patients had smaller tumors, and the percentage of patients with positive lymph nodes in the resection specimen was significantly less. The incidence of positive margins was similar between the two groups. Postoperative lengths of stay, complication rates, and perioperative mortality rates were not higher in reoperative patients. The long-term survival rate was similar between the two resected groups, with a median survival of 24 months in the reoperative group and 20 months in those without previous exploration. CONCLUSIONS: These data demonstrate that patients undergoing reoperation for periampullary carcinoma have similar resectability, perioperative morbidity and mortality, and long-term survival rates as patients undergoing initial exploration. The results suggest that selected patients considered to have unresectable disease at previous surgery should undergo restaging and reexploration at specialized high-volume centers.  (+info)

Prognostic value of MIB-1 index and DNA ploidy in resectable ampulla of Vater carcinoma. (3/323)

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.  (+info)

Pancreaticoduodenectomy with or without extended retroperitoneal lymphadenectomy for periampullary adenocarcinoma: comparison of morbidity and mortality and short-term outcome. (4/323)

OBJECTIVE: This prospective, randomized, single-institution trial was designed to evaluate the end points of mortality, morbidity, and survival in patients undergoing standard versus radical (extended) pancreaticoduodenectomy (including distal gastrectomy and retroperitoneal lymphadenectomy). SUMMARY BACKGROUND DATA: Numerous retrospective reports and one prospective randomized trial have suggested that the performance of an extended lymphadenectomy in association with a pancreaticoduodenal resection may improve long-term survival for some patients with pancreatic and other periampullary adenocarcinomas. Many of these previously published studies can be criticized for their retrospective and nonrandomized designs, for the inclusion of nonconcurrent control groups, and for their small numbers. METHODS: Between April 1996 and December 1997, 114 patients with periampullary adenocarcinoma were enrolled in an ongoing, prospective, randomized trial at The Johns Hopkins Hospital. After intraoperative verification of completely resected periampullary adenocarcinoma, the patients were randomized to receive either a standard pancreaticoduodenectomy (removing only the peripancreatic lymph nodes en bloc with the specimen) or a radical pancreaticoduodenectomy (standard resection plus distal gastrectomy and retroperitoneal lymphadenectomy). All pathology specimens were reviewed and categorized. The postoperative morbidity, mortality, and short-term outcomes were examined. RESULTS: Of the 114 patients randomized, 56 underwent a standard pancreaticoduodenectomy and 58 a radical pancreaticoduodenectomy. The two groups were statistically similar with regard to age and gender, but there was a higher percentage of white patients in the radical group. All the patients in the radical group underwent distal gastric resection, whereas 86% of the patients in the standard group underwent pylorus preservation. The mean operative time in the radical group was 6.8 hours, compared with 6.2 hours in the standard group. There were no significant differences between the two groups with respect to the intraoperative blood loss, transfusion requirements, location of primary tumor, mean tumor size, positive lymph node status, or positive margin status. There were three deaths in the standard group and two in the radical group. The complication rates were 34% for the standard group and 40% for the radical group. Patients undergoing radical resection had a higher incidence of early delayed gastric emptying but had similar rates of other complications, such as pancreatic fistula, wound infection, intraabdominal abscess, and need for reoperation. The mean total number of lymph nodes resected was higher in the radical group. Of the 58 patients in the radical group, only 10% had metastatic carcinoma in the resected retroperitoneal lymph nodes, and none of those patients had the retroperitoneal nodes as the only site of lymph node involvement. The 1-year actuarial survival rate for patients surviving the immediate postoperative periods was 77% for the standard resection group and 83% for the radical resection group. CONCLUSIONS: These data demonstrate that radical pancreaticoduodenectomy (with the addition of a distal gastrectomy and extended retroperitoneal lymphadenectomy to a standard pancreaticoduodenectomy) can be performed with similar morbidity and mortality to standard pancreaticoduodenectomy. However, the survival data are not sufficiently mature and the numbers of patients enrolled are not adequate to allow firm conclusions to be drawn regarding survival benefit.  (+info)

Bilateral ovarian carcinoma metastatic from the ampulla of Vater: a rare Krukenberg tumor. (5/323)

Carcinoma of the ampulla of Vater is a relatively rare neoplasm and its longterm survival rate is considerably high. However, because of differences in tumor pathologic features and local invasiveness, a 5-year survival rate differ widely. We present a case of metastatic carcinoma of the ampulla of Vater presenting as a Krukenberg tumor in a 59-year-old woman. Eight months earlier, she had been diagnosed as well-differentiated adenocarcinoma of the ampulla of Vater. Abdominal examination revealed a hard mass with mild tenderness in the RLQ area. The laboratory findings were unremarkable except for mild anemia. CT scan of the abdomen revealed enlargement of both ovaries. An exploratory laparotomy disclosed bilateral ovarian masses, 18 x 12 x 8 cm and 8 x 5.5 x 4 cm in size, respectively. Histologic findings of the both ovarian masses were consistent with metastatic adenocarcinoma from the ampulla of Vater.  (+info)

Germline and somatic mutations of the STK11/LKB1 Peutz-Jeghers gene in pancreatic and biliary cancers. (6/323)

Peutz-Jeghers syndrome (PJS) is an autosomal-dominant disorder characterized by hamartomatous polyps in the gastrointestinal tract and by pigmented macules of the lips, buccal mucosa, and digits. Less appreciated is the fact that PJS also predisposes patients to an increased risk of gastrointestinal cancer, and pancreatic cancer has been reported in many PJS patients. It was recently shown that germline mutations of the STK11/LKB1 gene are responsible for PJS. We investigated the role of STK11/LKB1 in the development of pancreatic and biliary cancer in patients with and without the PJS. In a PJS patient having a germline splice site mutation in the STK11/LKB1 gene, sequencing analysis of an intestinal polyp and pancreatic cancer from this patient revealed loss of the wild-type allele of the STK11/LKB1 gene in the cancer. Inactivation of STK11/LKB1, by homozygous deletions or somatic sequence mutations coupled with loss of heterozygosity, was also demonstrated in 4-6% of 127 sporadic pancreatic and biliary adenocarcinomas. Our results demonstrate that germline and somatic genetic alterations of the STK11/LKB1 gene may play a causal role in carcinogenesis and that the same gene contributes to the development of both sporadic and familial forms of cancer.  (+info)

Adenoma of the ampulla of Vater: a genetic condition? (7/323)

The etiology of adenoma of the ampulla of Vater is not well understood. Previous authors reported the association of this neoplasm with polycystic kidney disease of two fraternal sisters. They concluded that these two conditions were somehow related. We describe a case of ampullary adenoma associated with polycystic kidney disease. This presentation raises again the question of a possible link between these two diseases.  (+info)

Brain metastases from adenoendocrine carcinoma of the common bile duct: a case report. (8/323)

A 68-year-old man with metastatic brain tumors from adenoendocrine carcinoma of the common bile duct is reported. A common bile duct tumor and a metastatic liver tumor had been resected 6 years and 3 years prior to admission, respectively. Microscopically they showed two components; moderately differentiated tubular adenocarcinoma and neuroendocrine carcinoma. He presented with headache and vomiting and MRI revealed two metastatic brain tumors. They were successfully resected and radiotherapy was carried out. Histological diagnosis of the metastatic brain tumors was neuroendocrine carcinoma, but carbohydrate antigen (CA)-19-9 and carcinoembryonic antigen (CEA)-immunoreactive cells were observed without glandular pattern. Immunohistochemically serotonin and pancreatic polypeptide were detected, but somatostatin was not. As the endocrine cells demonstrated in the normal extrahepatic bile ducts are only somatostatin-containing D cells, these cells are considered to originate as part of a metaplastic process. To our knowledge, this represents the second case of adenoendocrine carcinoma of the common bile duct.  (+info)

Hi there - I was hoping to find out if there is anyone on this site who has had experience with Ampullary Adenocarcinoma.. My father was diagnosed with ampullary adenocarcinoma in March 2019 and he had successful Whipple Surgery in May 2020, followed by chemo for 6 months. He was given the all clear earlier this year. Unfortunately we heard last Friday that he now has Liver Metastases, Stage 4. He is otherwise pretty healthy and walks around 2 hours a day and plays golf 2 to 3 times a week (without a buggy/cart).. I am based in California but he is based in the UK and has had all the previous treatments and surgery in the UK. As we havent had the greatest response for potential treatments there we are exploring options in the USA (or anywhere in the world) and wanted to see if there may be some other possible treatments/surgery available to him.. The initial oncologist in the UK said that it is inoperable and they suggested the chemo drugs Gemcitabine with Cisplatin.. We have reached out to ...
AIM: To investigate endoscopic ultrasound (EUS) for predicting depth of mucosal invasion and to analyze outcomes following endoscopic and transduodenal resection. METHODS: Records of 111 patients seen at our institution from November 1999 to July 2011 with the postoperative pathological diagnosis of benign ampullary and duodenal adenomas were reviewed. Records of patients who underwent preoperative EUS for diagnostic purposes were identified. The accuracy of EUS in predicting the absence of muscular invasion was assessed by comparing EUS reports to the final surgical pathological results. In addition, the incidence of the post-operative complications over a period of 30 d and the subsequent long-term outcome (recurrence) over a period of 30 mo associated with endoscopic and transduodenal surgical resection was recorded, compared and analyzed. RESULTS: Among 111 patients with benign ampullary and duodenal adenomas, 47 underwent preoperative EUS for 29 peri-ampullary lesions and 18 duodenal ...

Most people have surgery for large bowel (colon cancer) that hasnt spread. Your type of operation depends on where the cancer is in the bowel. You might have surgery to remove a small part of bowel lining. This is called a local resection. Or you might have surgery to remove all or part of your bowel. This is called a colectomy. ...
Periampullary cancers encompass a mixture of cancers but in general are separated into four subtypes: cancer in the head of the pancreas, distal bile duct cancer, true ampullary cancer, and duodenal cancer. These cancers arise in the vicinity of the ampulla of Vater and are differentiated by their histologic origins (pancreatic, distal bile duct, ampulla of Vater, or duodenum). While pancreatic adenocarcinoma makes up the majority of resected periampullary cancers at 62%, ampullary cancer accounts for 19%, distal bile duct cancer 12%, and duodenal cancer 7% of resected periampullary cancers.1 Although preoperative assessment with imaging and biopsy can distinguish one subtype from the other, often times the tumor origin may be undetermined preoperatively. Moreover, duodenal cancer in the periampullary region as well as intestinal-type ampullary cancer behave in a similar fashion, whereas distal bile duct cancer and pancreaticobiliary-type ampullary cancer behave similar to one another. While 56% ...

Summary Background Data: Many patients are referred to tertiary centers with periampullary carcinoma after their tumors were deemed unresectable at previous laparotomy. In carefully selected patients, tumor resection is often possible; however, the perioperative results and long-term outcome have not been well defined. Methods: From November 1991 through December 1997, 78 patients who underwent previous exploratory laparotomy and/or palliative surgery for suspected periampullary carcinoma underwent ...

Aims: Pancreatic adenocarcinoma is an aggressive gastrointestinal malignancy with only a few long-term survivors even after radical surgery. Patients with ampullary cancer have a better prognosis but adjuvant therapy needs further improvement. Epithelial cell adhesion molecule (Ep-CAM) is strongly expressed in a variety of epithelial cancers and represents a promising target for immunological tumour therapy. Thus, the aim of this study was to investigate Ep-CAM expression and its potential prognostic impact in pancreatic and ampullary carcinomas.. Methods: Ep-CAM expression was investigated retrospectively by immunohistochemistry in paraffin-embedded primary tumour tissue samples from a series of consecutive patients with pancreatic (n = 153) and ampullary cancer (n = 34).. Results: Ep-CAM overexpression was observed in 85 of 153 pancreatic cancer specimens (56%) and in 29 of 34 ampullary cancer samples (85%). Overall, Ep-CAM failed to be an independent prognostic marker. However, subgroup ...

Your treatment choices depend on the type of ampullary cancer you have, test results, whether the cancer can be removed with surgery, and the size and stage of the cancer. The goal of treatment may be to cure you, control the cancer, or to help ease problems caused by the cancer. Talk with your healthcare team about your treatment choices, the goals of treatment, and what the risks and side effects may be. Types of treatment for cancer are either local or systemic. Local treatments remove, destroy, or control cancer cells in one area. Surgery and radiation are local treatments. Systemic treatment is used to destroy or control cancer cells that may have traveled around your body. When taken by pill or injection, chemotherapy is a systemic treatment. You may have just one treatment or a combination of treatments. The main treatment for ampullary cancer is surgery to remove the tumor. The Whipple procedure (also called a pancreaticoduodenectomy) is used. This is a major surgery. During it, a ...
Tamoxifen treatment has previously been reported to confer life-prolonging effects in patients with advanced pancreatic cancer, and most evidently so in women. None of these trials did however include biomarkers, and the relevance of female hormone signaling in pancreatic or other periampullary adenocarcinoma remains largely unexplored. The aim of this study was to examine the extent and potential clinical significance of estrogen receptor-α (ER) and progesterone receptor (PR) expression in pancreatic and other periampullary cancers. ER and PR expression was examined using immunohistochemistry on tissue microarrays with primary tumors from a retrospective consecutive cohort of 175 patients with resected periampullary adenocarcinoma, with long-term clinical follow-up. Non-parametric and Chi square tests were applied to examine the associations of stromal ER and PR expression with patient and tumor characteristics. Kaplan-Meier analysis and log rank test were applied to illustrate survival differences in

N2 - The impact of lymphadenectomy in prognosis and staging in periampullary malignancies remains largely undefined. We examined all pancreaticoduodenectomies for periampullary carcinomas in the SEER cancer registry from 1993 through 2003. Overall, 5465 pancreaticoduodenectomies for nonmetastatic periampullary carcinomas were identified. The cohort was comprised of 62.5% pancreatic, 18.9% ampullary, 11.6% distal bile duct, and 7.0% duodenal cancers. A linear association between the number of lymph nodes (LNs) examined and overall survival was observed overall and for pancreas and ampullary cancers for node-negative (N0) disease. Median survival for all patients with localized, N0 disease improved from 24 to 31 months, with sampling of a minimum of 10 LNs, whereas 2 and 5-year survival improved from 52 and 29%, ...

Victor Maciel, MD. St. Vincent Hospital. Background: Ampullectomy is mostly performed for periampullary malignancies, however, some benign disease may benefit from ampullectomy too. Transduodenal ampullectomy requires a precise dissection and complex reconstruction. Our group has been performing robotic ampullectomies for sphincter of Oddi dyskinesia (SOD) since 2005 with good results. The introduction of robotic techniques to our practice opened the possibility of performing this technically challenging operation with a minimally invasive approach and the added benefit of articulating instruments which -we believe- result in a better intra-abdominal suturing. We studied all consecutive cases of robotic ampullectomies for SOD performed since 2005 to date (n=13). Demographics, intraoperative and postoperative complications, length of stay, blood loss and operative times were recorded. Our main goal was to discuss the robotic ampullectomy technique and to evaluate the early results of this ...
Recently, immunohistochemistry-based classifications of ampullary carcinomas have been proposed (Ang and colleagues [PMID: 24832159]; Chang and colleagues [PMID: 23439753]). In this study, the prognostic value of Ang/Chang panel markers (CK20, MUC1, MUC2, CDX2) as well as other markers (CK7, MUC5AC, and MUC6) were tested on full-faced sections of 136 ampullary carcinoma resections with substantial (,5 mm) invasion. Immunohistochemistry was correlated with both histologic classification (intestinal [INT], pancreatobiliary [PB], or nontubular based on ≥3/5 observer agreement) and clinical outcome. No prognostic correlation was found with MUC1, CDX2, MUC2 or CK20 despite testing with different quantitative cutoffs. CK7 and CK20 were nonspecific. Ang classification had reasonable correlation with histologic subclassification of tubular cases as INT versus PB with high specificity but low sensitivity and ambiguous category was large (29%) and included also some classical cases. Prognostically, Ang ...
Migration of a biliary self-expanding metallic stent (SEMS) may occur proximally or distally after placing a stent for the palliative treatment of patients with unresectable periampullary malignancy. However, migration of a biliary SEMS into the stomach has not yet reported in the English medical literature. Herein we report on a case of periampullary cancer for which a stent that was placed to treat this malady migrated into the stomach. A biliary SEMS had been placed in the distal common bile duct in an 82-year-old woman who was diagnosed with periampullary cancer. The abdominal CT and esophagogastroduodenoscopic findings disclosed that the biliary SEMS had migrated into the stomach and there was marked luminal narrowing of the second portion of the duodenum due to the enlarged periampullary tumor. The migrated stent was easily removed by using a polypectomy snare. We presume that the distally migrated SEMS might have moved into the stomach against the normal direction of peristaltic movement ...

A 76-year-old female with Ampulla of Vater carcinoma.A. The five-day follow-up plain film after stent insertion shows good stent positioning on the air-biliary
Carcinoma of the ampulla of Vater is a malignant tumor arising in the last centimeter of the common bile duct, where it passes through the wall of the duodenum and ampullary papilla. The pancreatic duct (of Wirsung) and common bile duct merge and exit by way of the ampulla into the duodenum.
BackgroundThe clinical management of pancreatic and other periampullary neoplasms remains challenging. In contrast to other cancer types, immunotherapies are largely ineffective, and the reason for the deprived immune response and the immune inhibiting cellular composition is only fragmentarily understood. The aim of this study was to comprehensively map the abundance, topographic distribution and spatial interaction of innate and innate-like immune cells in the tumor microenvironment of periampullary adenocarcinoma.MethodsMultiplexed immunofluorescent imaging was performed on tissue microarrays with tumors from a consecutive cohort of 175 patients with resected periampullary adenocarcinoma. To obtain a detailed spatial analysis of immune cell infiltration, two multiplex immune panels including antibodies against CD3, NKp46, CD56, CD68, CD163 and CD1a, CD208, CD123, CD15, CD68 and pan-cytokeratin were applied.ResultsThe infiltration of natural killer (NK) and NK-like T (NKT) cells was lower in malignant

There are no specific blood tests for the diagnosis of pancreatic carcinoma. Abnormal liver function tests cannot reliably distinguish biliary obstruction (of any cause) from hepatic metastases. The most useful initial investigation seems to be abdominal ultrasonography which can identify the pancreatic tumour, as well as dilated bile ducts, and will save considerable time and inconvenience if liver metastases are identified. The reported sensitivity of ultrasonography in the detection of pancreatic carcinoma is as high at 80-95%.51-53 The technique however, becomes less sensitive in evaluating the body and tail and provides less accurate staging information than other modalities, such as CT.54,55 Technical difficulties with bowel gas compromise interpretation in 20-25% of subjects,56 and interobserver variation continues to be a problem.53 Improvements in ultrasound technology, with inclusion of colour Doppler, may improve staging accuracy, particularly with respect to vascular ...
To assess the feasibility of administering induction chemotherapy with gemcitabine and docetaxel followed by concurrent radiation and continuous infusio
Cancer of the ampulla of Vater must be differentiated from cancer of the head of the pancreas. Prognosis and potential therapeutic intervention are different. 87% of patients with carcinoma of the ampulla and 47% of those with a malignancy of the duodenum have a potentially operable tumour compared with only 22% of patients with tumours arising from the head of the pancreas [2, 12]. Therefore a noninvasive accurate technique for detection and staging is mandatory for these patients.. The endoscopic appearance of the papilla was abnormal in most of our patients. However the distinction between an impacted stone, a benign tumour or a malignancy is not always feasible. ERCP with endoscopic sphincterotomy was a helpful diagnostic procedure in cases of intraampullary tumors with a protruding papilla. In 3 cases of our patients a polypoid mass was evident only after sphincterotomy. However, ERCP is an invasive procedure with a considerable morbidity.. Moreover, endoscopic biopsies do not always allow ...
Continuing part two of our mini-series on colorectal cancer, today we move from the big scale Immunoscore study to small subsets of disease that are looking interesting in several ways.. For years, advanced colorectal cancer has been dominated by chemotherapy (FOLFOX or FOLFIRI) with and without targeted therapies (VEGF and EGFR antibodies), with very little new to talk about. Part of the challenge here is how do you add something the existing standard of care and move the needle significantly. In front-line, for example, the OS is already out 2-plus years, so these are long and risky trials to undertake. Not surpisingly, many companies have sought to evaluate their agents in tumour types where they consider the risk of development to be lower.. Unless… we can find creative approaches that turn the paradigm on its head and identify a clearly defined niche that can be carved out separately from allcomers.. This is where were at now - identifying subsets that might respond exquisitely to novel ...

Weve heard plenty from politicians and experts on affirmative action and higher education, about how universities should intervene-if at all-to ensure a diverse but deserving student population. But what about those for whom these issues matter the most? In this book talk, Natasha K. Warikoo deeply explores how students themselves think about merit and race at a uniquely pivotal moment: after they have just won the most competitive game of their lives and gained admittance to one of the worlds top universities. What Warikoo uncovers-talking with both white students and students of color at Harvard, Brown and Oxford-is absolutely illuminating, and some of it is positively shocking. As she shows, many elite white students understand the value of diversity abstractly, but they ignore the real problems that racial inequality causes and that diversity programs are meant to solve. They stand in fear of being labeled racist, but they are quick to call foul should a diversity program appear at all to ...
We found sensitivity for the ascertainment of pancreatic and periampullary cancer cases from the hospital data of 87.5% for the 2005-2009 period. The accuracy of hospital coding varied by tumour primary site and histology, with higher sensitivity of case ascertainment for pancreatic (88.6%) and duodenal cancers (87.1%) compared with extrahepatic bile duct and ampullary cancers (78.8%) and with lower sensitivity for extrahepatic cholangiocarcinomas (67.9%). Misclassification of pancreatic and periampullary cancers in the hospital data was often to closely related sites, for example, intrahepatic bile duct carcinoma, or to less specific sites such as cancers of ill-defined or unspecified primary sites. Whereas hospital coders might only have information from a particular admission available, coders at a cancer registry often have multiple sources of information from diagnostic procedures and treatment which can enable more accurate coding of tumour characteristics.. Several aspects of the coverage ...
Ampullary cancer, or ampullary carcinoma, is a life-threatening cancer that forms in a body part called the ampulla of Vater in the duodenum, where the pancreatic and bile ducts release their secretions into the intestines.

BACKGROUND: Pancreatic and periampullary adenocarcinomas account for some of the most aggressive malignancies, and the leading causes of cancer-related mortalities. Partial pancreaticoduodenectomy (PD) with negative resection margins is the only potentially curative therapy. The high prevalence of lymph node metastases has led to the hypothesis that wider excision with the removal of more lymphatic tissue could result in an improvement of survival, and higher rates of negative resection margins. OBJECTIVES: To compare overall survival following standard (SLA) versus extended lymph lymphadenectomy (ELA) for pancreatic head and periampullary adenocarcinoma. We also compared secondary outcomes, such as morbidity, mortality, and tumour involvement of the resection margins between the two procedures. SEARCH METHODS: We searched CENTRAL, MEDLINE, PubMed, and Embase from 1973 to September 2020; we applied no language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCT) comparing PD with ...

Purpose: MEK inhibition has clinical activity against biliary cancers, and might therefore be successfully combined with gemcitabine; one of the most active chemotherapy agents for these cancers. As gemcitabine is active in S-phase, and the ERK pathway has a major role driving cell cycle progression, concurrent use of a MEK inhibitor could potentially antagonize the effect of gemcitabine. We therefore tested the sequence dependence of the combination of gemcitabine and the MEK inhibitor AZD6244 using a series of biliary cancer models. Experimental Design: Primary xenografts were established from patients with gallbladder and distal bile duct cancer, and grown in SCID mice at the subcutaneous site. Plasma and tumor drug levels, and the time course for recovery of ERK signaling and S-phase were measured in tumor-bearing mice treated for 48hr with AZD6244 and then monitored for 48hr off treatment. Based on these results, two different treatment schedules combining AZD6244 with gemcitabine were ...

Large cell neuroendocrine carcinoma in the salivary glands is rare. We report a second case of large cell neuroendocrine carcinoma of the submandibular gland diagnosed at autopsy, and a review of the literature. A 68-year-old Japanese man was referred to our hospital for thorough investigation of swelling on the right side of his neck. Fine-needle aspiration cytology of the cervical mass suggested poorly differentiated metastatic carcinoma. The primary tumor could not be detected by several examinations. One month after admission, he died of cancer. An autopsy was performed, and it revealed a tumor of the right submandibular gland. The histopathological diagnosis was large cell neuroendocrine carcinoma of the submandibular gland. To the best of our knowledge, only eight cases of large cell neuroendocrine carcinoma in the salivary glands, including our case, have been reported. This report indicates total biopsy and immunohistochemistry are necessary for diagnosing large cell neuroendocrine carcinoma
Preoperative biliary drainage methods include percutaneous transhepatic biliary drainage (PTBD), endoscopic nasobiliary drainage (ENBD), and endoscopic retrograde biliary drainage (ERBD). Endoscopic biliary drainages often induce peritumoral inflammation and it increase difficulties in determining a proper resection margin.

The major duodenal papilla is an opening of the Common bile duct and Pancreatic duct into the duodenum. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion. The major duodenal papilla is situated in the second part of the duodenum, 7-10 cm from the pylorus, at the level of the second or third lumbar vertebrae. It is surrounded by the sphincter of Oddi, and receives a mixture of pancreatic enzymes and bile from the Ampulla of Vater, which drains both the pancreatic duct and biliary system. The junction between the foregut and midgut occurs directly below the major duodenal papilla. The major duodenal papilla is seen from the duodenum as lying within a mucosal fold. The minor duodenal papilla is situated 2cm proximal. The major duodenal papilla is occasionally found in the third part of the duodenum, the level of the vertebrae may be L2-3, and in about 10% of people, it may not receive bile. Additionally, in a ...

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 ...
Adult cystic adenomyoma shows clinical features similar to those of common adenomyosis, which is usually found in multiparous women over age 30, and is considered a rare variant of adenomyosis characterized by the presence of a hemorrhagic cyst resulting from menstrual bleeding in the ectopic endometrial gland in the myometrium. However, juvenile cystic adenomyoma has different clinical characteristics than those in adult cystic adenomyoma. The pathognomonic clinical feature of juvenile cystic adenomyoma is its early onset of severe dysmenorrhea that usually starts with menarche. This symptom can be attributed to intra-cystic bleeding and stretching of the cystic cavity. Medical treatment with GnRH agonist only provides temporary relief. Surgery remains the main method of treatment. The most common location of this lesion is the anterior wall of the uterus at the level of the insertion of the round ligament. The physical appearance should be differentiated from a Mullerian anomaly. Following a ...

TY - CHAP. T1 - Endoscopic diagnosis and resection therapy of the Tumor of the major duodenal papilla. AU - Itoh, Akihiro. AU - Hirooka, Yoshiki. AU - Goto, Hidemi. PY - 2008/12/1. Y1 - 2008/12/1. N2 - Endoscopic ultrasonography and intraductal ultrasonography (IDUS) are useful for diagnosing tumor extension of the major duodenal papilla. Especially, IDUS makes it possible to diagnose early cancer that has never been correctly diagnosed by other modalities. On the other hand, we think that endoscopic resection therapy of the tumor that is benign adenoma or early cancer may be initially selected as a curative treatment similar to, endoscopic mucosal resection for early gastric or colonic cancer. Between 1993 and 2007, 91 patients with tumor of the duodenal major papilla underwent, endoscopic resection therapy at our institute. The indication for this therapy was defined as a case with adenoma or early cancer without infiltration into the bile and pancreatic ducts. The tumors were resected in a ...

Background Delayed gastric emptying (DGE) is a major postoperative problem after pylorus-preserving pancreatoduodenectomy (PpPD) and sometimes causes reflux esophagitis. demonstration A 63-year-old GW843682X guy underwent Kid and PpPD reconstruction with Braun anastomosis for lower bile duct carcinoma. Fourteen days after medical procedures DGE happened and a 10?cm lengthy stricture from middle esophagus to cardia developed one . 5 month after medical procedures regardless of the administration of antacids. Balloon dilation was performed but occurred. It was retrieved with traditional treatment. Actually the administration of the proton GW843682X pump inhibitor (PPI) for about five mouths didnt improve esophageal stricture. Simultaneous 24-h bilirubin and pH monitoring verified that affected person was resistant to PPI. We performed middle-lower esophagectomy with total gastrectomy to avoid gastric acidity from injuring reconstructed body organ and remnant esophagus through the right ...
