Abstract
OBJECTIVES The aim of this multicenter retrospective study was to identify the optimal chemotherapeutic regimen for advanced pancreatic acinar cell carcinoma (PACC). METHODS Fifty-eight patients with histopathologically confirmed advanced PACC who had received chemotherapy between 1996 and 2013 were enrolled. The clinical characteristics of the patients and the treatment efficacy data were collected from the medical records at 16 Japanese institutions, using standardized data collection instrument. RESULTS The most commonly selected treatment regimens were gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens. The overall response rate in the patients who received first-line chemotherapy were 7% and 38%, respectively, and the median overall survival was 13.2 months. When the data for all the treatment lines were aggregated, the response rates to gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens were 7%, 18%, 40%, and 29%, respectively. The overall survival tended to be better in patients who had received a platinum-containing regimen (hazard ratio, 0.50; 95% confidence interval, 0.23-1.11; P = 0.08) or irinotecan-containing regimen (hazard ratio, 0.42; 95% confidence interval, 0.15-1.19; P = 0.09) at least once in the treatment course as compared with those who had not. CONCLUSIONS Our findings suggested that platinum- and irinotecan-containing regimens exhibited some potential efficacy in patients with advanced PACC.

Abstract
A 59-year-old man was admitted to the hospital with acute pancreatitis. The cause was suggested to be a pancreatic tumor based on computed tomography (CT). The pancreatic tumor was 45 mm with an extensive tumor embolism at the trunk of the portal vein and intraductal infiltration of the main pancreatic duct (MPD). The pancreatic tumor was diagnosed as acinar cell carcinoma (ACC) by endoscopic ultrasound guided fine needle aspiration. Therefore, the cause of acute pancreatitis was diagnosed to be intraductal infiltration of ACC in the MPD. Chemotherapy was initially performed because it was difficult to perform surgery due to extensive tumor embolism at the trunk of the portal vein. Degeneration and reduction of ACC and tumor embolism of the portal vein was noted on CT after chemotherapy, and extended distal pancreatectomy with portal vein reconstruction was performed. There has been no relapse for 5 years postoperative follow-up. This is an interesting and rare case because ACC with intraductal infiltration of MPD is low in frequency; most ACCs are asymptomatic when they are found, and many cases tend to have poor prognosis in spite of surgical cases.

Abstract
Pancreatic acinar cell carcinoma (ACC) is a rare tumor that is difficult to diagnose preoperatively. The aim of this study was to evaluate and describe the computed tomography (CT) features of ACC and compare the results with pancreatic ductal adenocarcinoma (DAC) for improving preoperative diagnosis. The control group consisted of 34 patients with DAC collected from the pathology electronic database. The CT imaging from nine patients with pathologically confirmed ACC was retrospectively reviewed. Two radiologists independently assessed the tumor location, size, texture, and enhancement patterns. We found that 64.3% (9/14) of ACC tumors were homogeneous and 35.7% (5/14) had necrosis. The percentage of common bile duct and pancreatic ductal dilation was 14.3% (2/14) and 7.1% (1/14), respectively. The mean size of ACC was 50.1±24.2 mm. The mean attenuation of ACC was 35.4±3.9 Hounsfield unit (HU) before enhancement, 73.1±42.9 HU in arterial phase, and 71.8±15.6 HU in port venous phase. It is difficult to distinguish ACC from DAC preoperatively only based on CT findings. However, compared with DAC, we found that ACC tumors are likely to be larger and contain more heterogeneous intratumoral necrotic hypovascular regions, and less pancreatic ductal and common biliary dilation.

Abstract
Pancreatic acinar cell carcinoma (ACC) is a rare malignant neoplasm that accounts for 1–2% of all pancreatic neoplasms. Here we report two cases of ACC and describe their clinical features, the therapies used to treat them, and their prognosis. The first patient was a 65-year-old woman who had an abdominal CT scan for a urinary infection. Fortuitously, a rounded and well-delimited corporeal pancreatic tumor was discovered. An endoscopic ultrasound (EUS)-guided fine needle aspiration revealed an ACC. During the puncture, a hypoechoic cavity appeared inside the lesion, corresponding to a probable necrotic area. Treatment consisted of a distal splenopancreatectomy. The second patient was a 75-year-old man who complained of abdominal pain. An abdominal CT scan showed a cephalic pancreatic lesion and two hepatic metastases. An EUS-guided fine needle aspiration showed a pancreatic ACC. The patient received chemotherapy with gemcitabine plus oxaliplatin (GEMOX regimen), which enabled an objective response after 6 cycles.

Abstract
Pancreatic acinar cell carcinoma (ACC) is a rare entity. Herein we present the case of a 50-year-old male patient with an unlimited mass on the pancreatic corpus and tail with peripancreatic effusion and multiple metastases in the liver and spleen. A liver biopsy showed a pancreatic ACC. The patient received 9 cycles of gemcitabine plus oxaliplatin (GEMOX regimen), which had to be stopped because of a persistent grade 2 neuropathy. A CT scan showed complete response after 14 years. At the age of 61 years, a localized prostatic cancer was diagnosed, treated by prostatectomy. The patient carried a BRCA2 mutation. None of the precedent case reports describe a chemosensibility to the GEMOX regimen. In spite of the lack of study in these patients, chemotherapy with oxaliplatin seems to be the most effective. Long survival can be expected.

Abstract
Acinar cell carcinoma (ACC) of the pancreas is a rare pancreatic tumor with poor prognosis. We present the first case of ACC of the pancreas successfully controlled by S-1 combined with a colorectal regimen. A 49-year-old Japanese female was referred to our clinic for right upper quadrant pain. Imaging studies demonstrated 2 solid tumors under the pancreas, and pancreatoduodenectomy with tumor resection was performed. Based on pathologic examination, the diagnosis of ACC of the pancreas was made according to the World Health Organization criteria. Eleven months after surgery, lymph node recurrence with elevations in serum concentrations of carbohydrate antigens (CA) 19–9 and CA125 were recognized. Treatments with carboplatin combined with paclitaxel, docetaxel, and gemcitabine, respectively, were attempted; however, there were no significant responses to these regimens. After starting S–1/irinotecan combination chemotherapy (IRIS), the concentrations of the tumor markers declined, accompanied by a reduction in tumor size. Because S-1 is an oral anticancer agent used on an outpatient basis with a low incidence of side effects, we believe that S–1-based chemotherapy is a strong candidate for the first-line treatment of recurrent or unresectable ACC.

Abstract
Pancreatic acinar cell carcinoma (PACC) is a rare pancreatic tumor, with an estimated frequency of less than 1% of pancreatic malignancies. There are no prospective studies to guide diagnostic or therapeutic algorithms. We report the case of a 36 year-old woman, diagnosed of a pancreatic tumor with liver and peritoneal metastases that was initially managed as a neuroendocrine tumor with temozolomide and capecitabine. After two cycles a severely painful arthritis developed in her left ankle with panniculitis and extensive fat necrosis, and CT scan demonstrated progressive disease. Pathology of the primary was reassessed establishing the diagnosis of PACC. The patient started treatment with FOLFIRINOX regimen, achieving clinical benefit and disease stabilization. We also briefly reviewed the literature on this rare subtype of pancreatic tumor.

Abstract
Current case is the third report of S-1 chemotherapy against acinar cell carcinoma (ACC) of pancreas, and our patient has achieved the longest reported recurrence-free survival, longer than 6 years, despite the presence of disseminated nodules at laparotomy.A 77-year-old man presented with abdominal discomfort. Computed tomography showed a low-density tumor in the pancreas tail and the patient was referred for surgery. A 3-cm sized pancreatic tumor, with localized disseminated nodules, was detected on laparotomy. Distal pancreatectomy with concomitant resection of disseminated nodules was performed, and histopathological examination revealed an ACC. Oral S-1 chemotherapy was administered postsurgery, and the patient showed no sign of recurrence during 73 months of follow-up. This is the first report of long-term survivor of pancreatic ACC with peritoneal dissemination, following pancreatectomy and S-1 chemotherapy.Current case suggests a beneficial effect of S-1 chemotherapy in cases of ACC.

Abstract
OBJECTIVE To evaluate and describe the computed tomography features of pure acinar cell carcinoma (ACC) and its liver metastases. METHODS Thirty patients were evaluated. Two radiologists evaluated imaging findings for each tumor for size, location, internal density, enhancement, tumor calcifications, pancreatic, and common biliary ductal obstructions and metastases. RESULTS 70 % were male. Fourteen tumors were located in the pancreatic head, 14 in the tail, one in the neck, and one in the uncinate process. Abdominal pain was the most common presenting symptom (93 %), 20 % had pancreatitis and 17 % had obstructive jaundice. The average tumor size was 7 cm, 97 % of tumors were solid, well circumscribed (73 %); isodense to normal pancreatic parenchyma (40 %) on the non-contrast study, hypodense on the arterial (47 %), and hypodense on the portal venous (37 %) phase. 30 % patients had pancreatic ductal dilation, 10 % had pancreatic ductal ingrowth, 6 % had calcifications, and 20 % had central necrosis, and 31 % (5/16) showed biliary ductal dilation. At presentation, 50 % had metastatic adenopathy and 40 % patients had liver metastases, which typically were well circumscribed, hypoattenuating to the hepatic parenchyma on all the phases of contrast enhancement and had a lobulated margin. CONCLUSION ACCs of the pancreas often present as large, well circumscribed, solid masses commonly in males. Despite their large size, they may not cause CBD obstruction.

Abstract
Acinar cell carcinoma of the pancreas is an uncommon malignancy, accounting for less than 1% of all pancreatic neoplasms. Because of its rarity, only a few retrospective studies are available to help guide management. We report the case of a patient with metastatic ACC who achieved prolonged survival as a result of personalized treatment designed in part on the basis of molecular and in-vitro data collected on analysis of the tumor and a cell line developed from the liver metastasis. To our knowledge, this represents the first human cell line of ACC. The molecular findings on this case and this patient's cell line may be of use in the management of future cases of this rare tumor and allow the identification of potential novel targets for the effective treatment of this disease.

Abstract
Background Acinar cell carcinoma (ACC) represents only 1–2% of pancreatic cancers and is a very rare malignancy. At the time of diagnosis only 50% of the tumors appear to be resectable. Reliable data for an effective adjuvant or neoadjuvant treatment are not available. Case presentation A 65-year old male presented with obstructive jaundice and non-specific upper abdominal pain. MRI-imaging showed a tumor within the head of the pancreas concomitant with Serum-Lipase and CA19-9. During ERCP, a stent was placed. Endosonographic fine needle biopsy confirmed an acinar cell carcinoma. Laparotomy presented an locally advanced tumor with venous infiltration that was consequently deemed unresectable. The patient was treated with five cycles of 5-FU monotherapy with palliative intention. Chemotherapy was well tolerated, and no severe complications were observed. Twelve months later, the patient was in stable condition, and CT-scanning showed an obvious reduction in the size of the tumor. During further operative exploration, a PPPD with resection of the portal vein was performed. Histopathological examination gave evidence of a diffuse necrotic ACC-tumor, all resection margins were found to be negative. Eighteen months later, the patient showed no signs of recurrent disease. Conclusion ACC responded well to 5-FU monochemotherapy. Therefore, neoadjuvant chemotherapy could be an option to reduce a primarily unresectable ACC to a point where curative resection can be achieved.

Abstract
AbstractAcinar cell carcinoma (ACC) of the pancreas is relatively rare, accounting for only approximately 1% of all exocrine pancreatic tumors. Because ACC of the pancreas is rare, strategy for management needs to be explored. The patient was a 50-year-old man who presented with left upper quadrant pain over 6 months. A mass lesion, located at the pancreatic tail, measuring approximately 4 cm in diameter was found on ultrasound, abdominal dynamic CT. The patient underwent a laparoscopic distal pancreatectomy. Immunohistochemical stains and electron microscopic examination of the tumor was consistent with ACC. No complication occurred, and the patient was discharged in good condition on 10th postoperative day. During the 10 months of follow-up, CT and tumor markers revealed no recurrence. In conclusions, Laparoscopic distal pancreatectomy can be performed safely for selected patients with nonmetastatic ACC at a favorable anatomic position. This operative strategy offers a minimally invasive surgery with the aim of a potential cure.

Abstract
INTRODUCTION Acinar cell carcinoma (ACC) is a rare, malignant neoplasm with a generally poor prognosis. We report our institutional series of 14 patients with ACC to determine current guidelines for their evaluation and treatment. MATERIALS AND METHODS The Johns Hopkins pathology prospective database was reviewed from 1988 to 2006 to identify patients with pancreatic neoplasms possessing features of acinar cell differentiation. Retrospective review and follow-up was performed for each patient. RESULTS Fourteen patients with ACC were identified with a median age of 57 years. All patients presented with abdominal pain or discomfort with none showing evidence of lipase hypersecretion syndrome. Each patient underwent surgical resection, including nine pancreaticoduodenectomies and five distal pancreatectomies. Median tumor size was 3.9 cm with 12 patients found to have stage IIB disease or worse. Four patients underwent neoadjuvant chemoradiation. Eight of the fourteen patients developed recurrent disease. Overall median survival and disease-free survival were 33 and 25 months, respectively, as compared to a median survival of 18 months for pancreatic adenocarcinoma. CONCLUSION Acinar cell carcinomas are rare, aggressive neoplasms that are difficult to diagnose and treat. Operative resection represents the best first-line treatment. These lesions have a better prognosis than the more common pancreatic adenocarcinomas.

Abstract
BACKGROUND Acinar cell carcinoma (ACC) is a rare cancer of the pancreas accounting for approximately 1% of nonendocrine tumors. Because no large series of patients with ACC exist, our understanding of this disease comes mainly from small retrospective reports and anecdotal experience. OBJECTIVE Our goal was to evaluate a large population-based cohort of patients with ACC and compare their demographic factors and outcomes to those of patients with pancreatic adenocarcinoma (PA). METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database (1988 to 2003), we identified all patients with ACC or PA. The demographic factors, tumor characteristics, resection status, and long-term survival were compared between the 2 groups. RESULTS A total of 672 patients with ACC and 58,526 with PA were identified. The mean age at the time of diagnosis was significantly lower for ACC than PA (56 years vs 70 years, P < .001). Compared with patients with PA, patients with ACC were more likely to be male (54% vs 48%, P = .007) and white (85% vs 81%, P = .03). Based on SEER clinical staging, patients with ACC were less likely to have unstaged disease (8% vs 18%). Of the 616 patients with staged ACC, 16% had localized disease, 26% had regional disease, and 58% had distant disease. In the 47,896 staged patients with PA, 10% had localized disease, 33% had regional disease, and 57% had distant disease (P < .0001 compared to ACC). Based on clinical extent of disease, 81% of patients with locoregional ACC and 70% of patients with locoregional PA were resectable. However, only 69% of ACC patients with locoregional disease and 27% of PA patients with locoregional disease underwent surgical resection. The overall 5-year survival was 42.8% for ACC (median, 47 months) and 3.8% for PA (median, 4 months, P < .0001). Patients with unresected ACC had a 5-year survival rate of 22% compared to 2% in patients with unresected PA (P < .0001). Surgical resection significantly improved survival. The 5-year survival was 72% in resected ACC and 16.3% in resected PA (P < .0001). Multivariate Cox proportional hazards regression model results suggested patients with ACC were less likely to die (hazard ratio = 0.241; 95% confidence interval, 0.22-0.27) than patients with PA after controlling for gender, race, stage, SEER region of diagnosis, and surgical resection status. CONCLUSIONS Consistent with anecdotal reports and previous retrospective studies, ACC is a more indolent disease than PA. Patients with ACC tend to present at a younger age, are more likely to have resectable disease, and are much more likely to undergo potentially curative resection. The long-term survival for patients with ACC is significantly better when compared to the long-term survival of patients with PA.

Abstract
BACKGROUND The finding of a solid or cystic mass in the pancreas is becoming more common secondary to the increasing use of cross-sectional imaging and the improved sensitivity of such studies for the detection of pancreatic abnormalities. Because of the aggressive natural history of pancreatic cancer, this has caused concern that all pancreatic abnormalities may be cancer as well as confusion over proper diagnostic and treatment algorithms. This review provides an overview of the natural history, diagnostic considerations, and treatment recommendations for the less common tumors of the pancreas which can be misinterpreted as pancreatic cancer including: solid pseudopapillary tumors (SPT), acinar cell carcinoma (ACC), lymphoplasmacytic sclerosing pancreatitis (LPSP), primary pancreatic lymphoma (PPL), and metastatic renal cell carcinoma to the pancreas. DATA SOURCES A Medline search was conducted to identify studies investigating the clinicopathologic features, molecular genetics, pathogenesis, diagnosis, and treatment of SPT, ACC, LPSP, PPL, and pancreatic metastases. CONCLUSIONS It is often possible to obtain an accurate pretreatment diagnosis for these unusual pancreatic tumors and to successfully differentiate them from the more common pancreatic malignancies.

Abstract
We herein report a rare case of ectopic pancreatic acinar cell carcinoma (ACC) which presented as a submucosal tumor of the pylorus. A 73-year-old man came to our hospital presenting with epigastralgia. Esophago-gastroduodenal endoscopy showed no mucosal lesions, but a submucosal tumor was observed around the pylorus. Abdominal computed tomography revealed two round masses. One was located in the pylorus, while the other was found between the portal vein and the inferior vena cava. An examination of a biopsy specimen was inconclusive. We diagnosed a gastrointestinal stromal tumor or malignant lymphoma preoperatively, and decided to perform an operation in order to confirm the diagnosis and select the optimal treatment. Intraoperatively, the mass in the pylorus invaded the pancreatic head, and the lymph node in the hepatoduodenal ligament was swollen. We performed a pancreaticoduodenectomy as a radical excision. The resected specimen showed the 7.6 x 4.9-cm size tumor to mainly originate from the pylorus. Histopathologically, the tumor was identified as pancreatic ACC with lymph node metastasis. The tumor cells were labeled by immunohistochemical staining for alpha1-antitrypsin. Because of the tumor location, we considered the tumor to have originated from the ectopic pancreatic tissue in the stomach. This is only the second case of ACC originating from an ectopic pancreas reported in the literature.

Abstract
OBJECTIVES Acinar cell carcinoma (ACC) of the pancreas is a rare tumor, and many aspects remain unclear because no large-scale clinical studies have been conducted. METHODS The present study investigated the clinical characteristics, treatment, and therapeutic outcomes of 115 patients registered in the Pancreatic Cancer Registry of the Japan Pancreas Society, and therapeutic plans were reviewed. RESULTS Although ACC has been associated with advanced stage and poor prognosis, this tumor was resectable in 76.5% of the patients, and the 5-year survival rate after resection was favorable, being 43.9%. CONCLUSIONS Confirming the diagnosis of ACC preoperatively is difficult, but this diagnosis should be kept in mind while planning surgery for ordinary pancreatic cancer. Once the diagnosis has been confirmed, a possibility of surgical resection should be pursued to achieve better prognosis. If ACC is unresectable or recurrent, chemotherapy is likely to prove useful. Multidisciplinary therapy centering on the role of surgery will need to be established.
