INTRODUCTION: The 2010 World Health Organization classification of intraductal neoplasms of the pancreas includes intraductal tubulopapillary neoplasms (ITPNs) and intraductal papillary mucinous neoplasms, the latter being a rare and new concept. ITPN sometimes cause acute pancreatitis; therefore, distinguishing ITPN from idiopathic acute pancreatitis is important but challenging. PRESENTATION OF CASE: We present the case of a 72-year-old male who had recurrent pancreatitis for the past 2 years, his diagnosis was idiopathic acute pancreatitis...

A 62-year-old man underwent endoscopic mucosal resection for early gastric cancer. The follow-up computed tomography revealed biliary dilatation. The tumor was located in the lower bile duct with biliary dilatation, and no evidence of metastasis in other organs was noted. The patient underwent subtotal stomach-preserving pancreatoduodenectomy with pancreaticogastrostomy and Billroth I anastomosis. At 13 months after the operation, gastrointestinal endoscopy revealed a tumor lesion in the pancreaticogastrostomy site...

OBJECTIVES: The management of branch-duct IPMN remains controversial due to the relatively low rate of malignant degeneration and the uncertain predictive role of high-risk stigmata (HRS) and worrisome features (WFs) identified by the 2012 International Consensus Guidelines. Our aim was to evaluate the evolution of originally low-risk (Fukuoka-negative) BD-IPMNs during a long follow-up period in order to determine whether the appearance of any clinical or morphological variables may be independently associated with the development of malignancy over time...

BACKGROUND: The management of metastatic Renal Cell Carcinoma (RCC) has changed dramatically in the last 20 years, and the role of surgery in the immunotherapy's era is under debate. Metastatic lesions interesting pancreas are infrequent, but those harbouring from RCC have an high incidence. If metachronous resections are not rare, synchronous resection of primary RCC and its pancreatic metastasis is uncommonly reported, and accounts for a bad prognosis. CASE PRESENTATION: We report the case of a 68 years old woman, who presented hematuria at hospital incoming, with radiological appearance of a 13 cm left renal mass, with a 2...

BACKGROUND: A paucity of data exists regarding the natural history and outcome measures of adenosquamous carcinoma of the pancreas (ASCP), a histology distinct from pancreatic adenocarcinoma (PDAC). The aim of this study is to characterize the clinicopathological features of ASCP in a large cohort of patients comparing outcome measures of surgically resected patients to PDAC. METHODS: We identified patients diagnosed with ASCP or PDAC from the National Cancer Database from 2004 to 2012...

Stem cells are considered the origin of neoplasms in general, and malignant tumours in particular, and the stage at which the stem cells stop their differentiation determines the degree of malignancy. However, there is increasing evidence supporting an alternative paradigm. Tumours may develop by dedifferentiation from mature cells able to proliferate. Studies of gastric carcinogenesis demonstrate that mature neuroendocrine (NE) cells upon long-term overstimulation may develop through stages of hyperplasia, dysplasia, and rather benign tumours, into highly malignant carcinomas...

Mucinous cystadenoma is a benign tumor commonly found in the pancreas, the ovaries or the appendix. Only very few cases of these tumors originating from the lungs have been reported worldwide, with even less cases describing malignant transformation. We present the case of a 58-year-old woman with a history of recurrent pulmonary infections who underwent left upper lobectomy for lung abscess and was initially diagnosed with pulmonary mucinous cystadenoma (PMCA). Upon thorough immunohistochemical workup, especially due to carcinoembryonic antigen (CEA) positivity, intramucinous singlet cells were eventually diagnostic for invasive carcinoma, in this case a mucinous cystadenocarcinoma arising from a PCMA...

BACKGROUND: Anaplastic carcinoma of the pancreas is a rare pancreatic neoplasm with a poor prognosis. It is classified as a variant of ductal adenocarcinoma, but the clinical features and treatment of it remain unknown because of its rarity and aggressiveness. Endoscopic ultrasonography and endoscopic ultrasound-guided fine-needle aspiration are useful techniques for the diagnosis of pancreatic tumors with high sensitivity and specificity. CASE PRESENTATION: A 72-year-old Japanese woman presented with a diagnosis of acute pancreatitis, and a cystic lesion with slightly high density area was observed by computed tomography in her pancreatic head...

BACKGROUND: A 68-year-old asymptomatic patient was incidentally diagnosed with an intraductal papillary mucinous neoplasia (IPMN) of the pancreas with a pancreaticogastric fistula. He had a history of a right sided nephrectomy due to a renal cell carcinoma 9 years before. The patient underwent an uneventful total pancreatectomy and wedge resection of the stomach. METHODS: The patient's medical history was studied and compared to recent literature via PubMed. RESULTS: Pathohistological evaluation confirmed a mixed type IPMN of an intestinal subtype with pancreaticogastric fistula...

As a type of malignant tumor developed at the pancreas, the prognosis of pancreatic carcinoma is usually poor, and >90% patients will sucumb to this disease <5 years after diagnosis. Therefore, early detection and treatment of this disease are important for improving the prognosis of patients. Long non-coding RNAs (lncRNAs) have been proven to serve pivotal functions in the development and progression of various tumors. The lncRNA HOXA distal transcript antisense RNA (HOTTIP), which serves an oncogenic role in different types of malignant tumors, has also been reported to be closely correlated with the migration and invasion of pancreatic carcinoma...

LL-37, the C-terminal peptide of human cathelicidin antimicrobial peptide (CAMP, hCAP18), reportedly increases resistance to microbial invasion and exerts important physiological functions in chemotaxis, promotion of wound closure, and angiogenesis. Accumulating evidence indicates that LL-37 also plays a significant role in human cancer. LL-37 induces tumorigenic effects in cancers of the ovary, lung, breast, prostate, pancreas, as well as in malignant melanoma and skin squamous cell carcinoma. In contrast, LL-37 displays an anti-cancer effect in colon cancer, gastric cancer, hematologic malignancy and oral squamous cell carcinoma...

We present a case of durable local control achieved in a patient treated with stereotactic magnetic resonance-guided adaptive radiation therapy (SMART) for an abdominal lymph node in the setting of oligometastatic breast cancer. A 50-year-old woman with a history of triple positive metastatic invasive ductal carcinoma of the left breast, stage IV (T3N2M1), underwent neoadjuvant chemotherapy, mastectomy, adjuvant radiotherapy and maintenance hormonal treatment with HER2 targeted therapies. At 20 months after definitive treatment of her primary, imaging showed an isolated progressive enlargement of lymph nodes between hepatic segment V/IVB and the neck of the pancreas...

Portal annular pancreas is a rare congenital anomaly in which the portal vein and/or the splenoportal confluence are completely encircled by aberrant pancreatic parenchyma. It is an asymptomatic condition and is usually an incidental finding. It is, however, important to a surgeon because the postoperative pancreatic fistula (POPF) rates following pancreatic resection are higher in patients with this anomaly. A 47-year-old male presented with features of obstructive jaundice. He was diagnosed to have periampullary carcinoma, and pancreatoduodenectomy was planned...

Pancreatic neoplasms, including ductal adenocarcinoma, solid pseudopapillary neoplasm, pancreatic endocrine neoplasms, acinar cell carcinoma, and pancreatoblastoma, are associated with different genetic abnormalities. Hepatic adenomas with beta-catenin exon 3 mutation are associated with a high risk of malignancy. Hepatic adenoma with arginosuccinate synthetase 1 expression or sonic hedgehog mutations are associated with a risk of bleeding. Hepatocellular carcinoma and choangiocarcinoma display heterogeneity at both morphologic and molecular levels Cholangiocellular carcinoma is most commonly associated with IDH 1/2 mutations...

The only way to cure the patient with adenocarcinoma of the pancreas (RT) is surgical excision of the tumor. The standard surgical treatment of resectable pancreatic carcinoma is considered the classic pancreatoduodenectomy (PD) with the Kausch- Whipple procedure, or the pylorus-preserving PD with the Traverso-Longmire method. The most difficult technically and at the same time the most important PD stage from an oncological point of view is the separation of the head of the pancreas from the superior mesenteric artery...

Knoevenagel condensation of 3,4-dichloro- and 2,6-dichloro- phenylacetonitriles gave a library of dichlorophenylacrylonitriles. Our leads 5 and 6 displayed 0.56±0.03 and 0.127±0.04 μM growth inhibition (GI₅₀) and 260-fold selectivity for the MCF-7 breast cancer cell line. A 2,6-dichlorophenyl moiety saw a 10-fold potency loss; additional nitrogen moieties (-NO₂) enhanced activity (26 and 27), with the corresponding -NH₂ analogues (29 and 30) more potent. Despite this, both 29 (2.8±0.03 μM) and 30 (2...

BACKGROUND: Patients with oligometastatic disease can benefit from local treatment of the metastases. Under these premises the resection of liver metastases and visceral metastases of non-gastrointestinal tumors is performed increasingly more frequently in selected patients. The aim of this study was to evaluate the role of visceral oncological surgery in hepatic oligometastatic disease of non-gastrointestinal tumors according to the currently available literature. MATERIAL AND METHODS: A systematic search of MEDLINE and PubMed was carried out focusing on the topics of oligometastases, liver resection and metastectomy for breast cancer, renal cell carcinoma, malignant melanoma, ovarian cancer and non-small cell lung cancer...

Diseases associated with the accumulation of lipid droplets are increasing in western countries. Lipid droplet biogenesis, structure and degradation are regulated by proteins of the perilipin family. Perilipin 5 has been shown to regulate basal lipolysis in oxidative tissues. We examine perilipin 5 in normal human tissues and in diseases using protein biochemical and microscopic techniques. Perilipin 5 was constitutively located at small lipid droplets in skeletal myocytes, cardiomyocytes and brown adipocytes...
