Abstract
Background Individuals with a very high lifetime risk of developing pancreatic ductal adenocarcinoma; for example, hereditary pancreatitis and main-duct or mixed-type intraductal papillary mucinous neoplasm, may wish to discuss prophylactic total pancreatectomy but strategies to do so are lacking. Objective To develop a shared decision-making programme for prophylactic total pancreatectomy using decision tables. Methods Focus group meetings with patients were used to identify relevant questions. Systematic reviews were performed to answer these questions. Results The first tables included hereditary pancreatitis and main-duct or mixed-type intraductal papillary mucinous neoplasm. No studies focused on prophylactic total pancreatectomy in these groups. In 52 studies (3570 patients), major morbidity after total pancreatectomy was 25% and 30-day mortality was 6%. After minimally invasive total pancreatectomy (seven studies, 35 patients) this was, respectively, 13% and 0%. Exocrine insufficiency-related symptoms occurred in 33%. Quality of life after total pancreatectomy was slightly lower compared with the general population. Conclusion The decision tables can be helpful for discussing prophylactic total pancreatectomy with individuals at high risk of pancreatic ductal adenocarcinoma.

High-grade atypical epithelial cells in pancreatic mucinous cysts are a more accurate predictor of malignancy than "positive" cytology. Cancer Cytopathol 2010; 118:434-40. [PMID: 20931638 DOI: 10.1002/cncy.20118] [Citation(s) in RCA: 106] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2010] [Revised: 09/09/2010] [Accepted: 09/10/2010] [Indexed: 12/20/2022]
Abstract
BACKGROUND The Sendai guidelines for risk assessment of malignancy in patients with mucinous cysts lists "positive" cytology as a high-risk feature. In the current study, the authors hypothesized that a cytological threshold of high-grade atypical epithelial cells (AEC) is a more accurate predictor of malignancy. METHODS The clinical, radiological, and cytological data of 112 patients with histologically confirmed mucinous cysts of the pancreas were reviewed. Cytology slides were blindly reviewed and cells were classified as benign, AEC, or malignant. On histology, neoplasms were grouped as benign (low-grade and moderate dysplasia) and malignant (high-grade dysplasia/carcinoma in situ and invasive carcinoma). RESULTS There were 92 patients with an intraductal papillary mucinous neoplasm (IPMN) and 20 with a mucinous cystic neoplasm; 39 were malignant and 73 were benign (42 with low-grade dysplasia and 31 with moderate dysplasia). Only 28% (11 of 39) of the malignant cysts were cytologically malignant with a sensitivity of 29%, a specificity of 100%, and an accuracy of 75%. AEC detected 17 additional cancers (44% of all malignant cysts; 16% more than detected on the basis of "positive" cytology). By using AEC as a surgical triage threshold, the sensitivity was 72%, the specificity was 85%, and the accuracy was 80%, with similar values for small (≤ 3 cm) branch duct IPMN. Nine of 73 (12%) benign cysts were identified with AEC, 4 of which had moderate dysplasia. AEC had a positive predictive value of 87% for the detection of a mucinous cyst with moderate dysplasia or worse. CONCLUSIONS AEC are a more accurate predictor of malignancy than "positive" cytology in aspirates of pancreatic mucinous cysts, including small branch duct IPMN. AEC warrant a "suspicious" interpretation for appropriate surgical triage.

Intraductal papillary-mucinous neoplasms of the gastric and intestinal types may have less malignant potential than the pancreatobiliary type. Pancreas 2010; 39:604-10.

Abstract
OBJECTIVES Intraductal papillary-mucinous neoplasms (IPMNs) of the pancreas are classified into 4 types--gastric, intestinal, pancreatobiliary, and oncocytic--on the basis of their morphology and immunohistochemistry. We classified IPMNs at our institute and used this classification to determine the clinicopathological features, prognosis, and malignant potential of the 4 types. METHODS Sixty-one patients with IPMN who underwent surgery between 2000 and 2007 were evaluated retrospectively. RESULTS There were 24 tumors of the gastric type, 22 intestinal, 12 pancreatobiliary, and 3 oncocytic. Patients with the intestinal or gastric type had a better prognosis than those with the pancreatobiliary type. The intestinal and pancreatobiliary types had almost the same frequencies of carcinoma, but the intestinal type tended to have a lower frequency of invasive carcinoma than the pancreatobiliary type. Patients with invasive carcinomas derived from intestinal-type IPMNs tended to have a better prognosis than those whose invasive carcinomas were derived from the pancreatobiliary type. CONCLUSIONS Intraductal papillary-mucinous neoplasm of the gastric and intestinal types may have less malignant potential than that of the pancreatobiliary type. Invasive carcinomas derived from intestinal-type IPMNs may be less invasive and slower growing than those derived from the pancreatobiliary type.

Abstract
BACKGROUND/PURPOSE This study was designed to establish institutional indications for pancreatic islet transplantation by examining patients with total pancreatectomy as candidates for islet allotransplantation. METHODS In 12 patients who underwent total pancreatectomy, we compared pre-and postoperative plasma glucose level, body mass index, HbA1c, and daily insulin use; we examined candidacy for islet allotransplantation based on the guidelines of Japan's islet transplantation registry. RESULTS Eight of the 12 patients with total pancreatectomy were operated for intraductal papillary mucinous neoplasm. At our institution, the 5-year survival of patients with intraductal papillary mucinous neoplasm was far better (76.3%) than that of patients with pancreatic cancer. Postoperatively, plasma glucose level, HbA1c, and daily insulin use were increased in all patients with total pancreatectomy. Of the 12 patients treated with total pancreatectomy, 4 (intraductal papillary mucinous neoplasm, n = 2; islet cell tumor, n = 1; and acute pancreatitis due to arteriovenous malformation, n = 1) showed deteriorated diabetic control and therefore were considered to be candidates for islet allotransplantation according to the guidelines. CONCLUSIONS Islet allotransplantation could be indicated for patients with favorable postoperative survival who have had a total pancreatectomy for either benign or neoplastic disease.

Abstract
In intraductal and papillary mucinous neoplasm (IPMN) of the pancreas, the aims of surgery differ according to the presence of malignancy. For malignant IPMN and especially for invasive malignancy, radical resection is essential, but entails a substantial operative risk and long-term pancreatic insufficiency. For benign IPMN, in theory, the operative risk and the loss of pancreatic function should be minimal. Thus, surgery for malignant and benign IPMN differs in patient selection, surgical technique, and accepted risk of long-term functional disorders. This article details the indications, surgical techniques, and results of surgery in IPMN.

Abstract
Intraductal papillary mucinous neoplasm (IPMN) is characterized by enhanced mucus secretion. It is a benign or low-grade neoplasm associated with a dilated main pancreatic duct, patulous ampullary orifice, and abundant mucus secretion. Foci of aggressive cancer may arise and become invasive. Surgery is the only treatment that can cure IPMN, but the extent of pancreatic resection and the intraoperative margins remain areas of controversy. The risks of total pancreatectomy must be weighed against the risk for developing cancer in the residual pancreas. Risks must be factored against the natural course of the disease and the likelihood of malignancy developing over the life expectancy.

Abstract
BACKGROUND/AIM Management of patients with small (1-3 cm) branch duct intraductal papillary mucinous neoplasms (IPMN) is a challenge. Symptoms, dilated duct, mural nodule or positive cytology have been proposed as parameters for resection. The aim of our study was to compare this proposed algorithm to one that incorporates cytology with less than malignant epithelial cells and cyst fluid carcinoembryonic antigen (CEA). METHODS A retrospective study was conducted. RESULTS There were 14 nonmalignant and 6 malignant cysts with 3 invasive IPMN. None were associated with a dilated duct and none had positive cytology. Only a mural nodule was significant by univariate analysis for the detection of malignancy (p = 0.01) and invasion (p = 0.009). The detection of atypical epithelial cells or a cyst fluid CEA of >2,500 ng/ml was more accurate for the detection of malignancy than using the recommended algorithm. CONCLUSIONS The presence of a mural nodule in a small branch duct IPMN is a predictor of malignancy and invasion by univariate analysis. Recognition of an atypical epithelial cell component in contrast to positive cytology or a cyst fluid CEA of >2,500 ng/ml is more accurate than the recommended algorithm and adds value to the preoperative assessment of clinically diagnosed small branch duct IPMN. and IAP.

Abstract
Required resection margins for noninvasive intraductal papillary mucinous neoplasms (IPMNs) are a controversial issue. Over a 10-year period we have resected IPMNs from the entire pancreatic gland with minimally invasive techniques and compared our survival and complication rates with open controls to see if any difference in resection margins and outcomes could be observed. Data were collected retrospectively, including our first cases of advanced laparoscopic resections. Five-year Kaplan-Meier curves were calculated and statistical analysis was performed using the log rank and Student's T test for continuous variables. Chi square and Fisher's exact tests were used for analyzing categorical variables. From March 1997 to February 2006, we operated on 22 patients with noninvasive IPMNs, of which 9 (41%) were operated on laparoscopically and 13 (59%) using open techniques. Three patients underwent laparoscopic duodenopancreatectomy, compared to five in the open group. All resection margins were negative, but two patients required total pancreatectomy, both of which were performed laparoscopically. One of these was converted to open (11%) because of difficulty in reconstructing the biliary anastomosis. The overall complication rates were 56% for the laparoscopic group and 85% for the open group. Twenty-two percent of the laparoscopic group required reoperation and 11% required percutaneous drainage, compared to 15 and 23% in the open group, respectively. All patients are alive after a mean of 20 months (range = 2-43) in the laparoscopic group and 37 months (range = 1-121) in the open one (p > 0.05). Laparoscopic resection of noninvasive IPMNs of the entire pancreatic gland has similar complication and survival rates as open procedures. As a result, the laparoscopic approach is appropriate for noninvasive IPMNs of the entire pancreatic gland; however, larger cohorts are needed to see if any approach has superior outcomes. Because of these favorable results, studies are currently underway to see if the minimally invasive approach is also appropriate for invasive IPMNs.

Abstract
Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are now a well-recognized category of slowly growing tumors with a remarkably better prognosis, even when malignant, than pancreatic ductal adenocarcinoma. Their clinical and pathohistologic features have been increasingly attracting the attention of clinicians since their first description 25 years ago. Despite its burgeoning volume recently, accumulated literature devoted to IPMN still provides a low level of evidence with regard to diagnosis, treatment, and prognosis. Therefore, we performed a Medline-based systematic review of the literature aimed at clearly defining the clinicopathologic characteristics of pancreatic IPMN and determining the best currently available evidence-based principles of diagnosis and management of patients with this disease.

Abstract
BACKGROUND Our objective was to predict malignancy for intraductal papillary mucinous neoplasms of the pancreas (IPMN) before operation. METHODS Sixty-four resected patients with IPMN were examined and 17 parameters were investigated for their relation to malignancy by univariate and multivariate analysis. RESULTS Multivariate logistic regression analysis showed that IPMN type, the size of main pancreatic duct, and serum carbohydrate antigen 19-9 were significant for malignancy. Size of the main pancreatic duct > or = 6.5 mm and serum carbohydrate antigen 19-9 > or = 35 U/mL scored 3 points, main duct type scored 2 points, and patulous papilla, jaundice, diabetes mellitus, and tumor size > or = 42 mm scored 1 point. When IPMNs with 3 and more than 3 points using the new score were diagnosed as malignant, accuracy was 90.6%. CONCLUSION This scoring system for IPMN is feasible to detect malignancy and useful for selecting an appropriate treatment.
