OBJECTIVE: To investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of patients with primary gastric adenosquamous cell carcinoma. METHODS: A total of 5 562 patients with gastric neoplasm were admitted in Tianjin Medical University Cancer Institute and Hospital from January 2001 to January 2011. Among them 42 patients were diagnosed as primary gastric adenosquamous cell carcinoma, accounting for 0.76% of all the patients. The clinicopathological and follow-up data of these 42 patients with primary gastric adenosquamous cell carcinoma were retrospectively analyzed, and Cox proportional hazard model was used to analyze the prognostic factors of gastric adenocarcinoma squamous cell carcinoma...

Pancreatic adenosquamous carcinoma coexisting with intraductal papillary mucinous neoplasm(IPMN)is extremely rare. We report a rare case of pancreatic adenosquamous carcinoma that developed after resection of intraductal papillary mucinous adenoma(IPMA). A 67-year-old man was suspected of having a pancreatic cystic lesion. MRCP demonstrated a cystic lesion measuring 25mm in the pancreatic tail, which had an enhanced nodule. We therefore diagnosed branch duct type IPMN of the pancreas. Although pancreatic juice cytology did not indicate malignancy, we performed laparoscope-assisted distal pancreatectomy...

A 69-year-old woman had gradually worsening abdominal discomfort over a year. A pancreatic mass was revealed by abdominal CT. The patient underwent FDG PET/CT for staging, which demonstrated the hypermetabolic pancreatic mass with multiple liver metastases. The lesion was pathologically confirmed as pancreatic adenosquamous carcinoma after biopsy.

A male patient aged over 60 years presented with abdominal pain. A solid lesion measuring 7cm was detected in the pancreatic body and tail, along with periaortic lymphadenopathy. Endoscopic ultrasound-guided fine-needle aspiration suggested squamous cell carcinoma. Nab-paclitaxel+gemcitabine therapy was effective;however, tumor progression was noted after the completion of the fourth course, and the patient died from the primary cancer 7 months after the initial consultation. Autopsy led to a definitive diagnosis of adenosquamous carcinoma of the pancreas...

Adenosquamous carcinoma (ASC) of the head and neck (H and N) is an aggressive variant of squamous cell carcinoma (SCC). They are described as SCC subtype with high infiltrative capacity and also presents with dual histomorphology, having both squamous and glandular cell components. ASC of the H and N region is considered as a controversial tumor, as it is similar to salivary gland mucoepidermoid carcinoma. It has been described in a variety of body sites, including uterine cervix, lung and pancreas. ASC rarely develops in the upper aerodigestive tract, particularly in the oral cavity...

Adenosquamous carcinoma (ASC) is an uncommon variant of pancreatic neoplasm. We sought to trace the mode of tumor progression using specimens of ASC associated with intraductal papillary mucinous neoplasm (IPMN) of the pancreas. A resected specimen of the primary pancreatic ASC, developed in a 72-year-old man, was subjected to mutation profiling using amplicon-targeted sequencing and digital polymerase chain reaction. DNA was isolated from each histological compartment including noninvasive IPMN, squamous cell carcinoma (SCC), and adenocarcinoma (AC)...

Cancer is the leading cause of morbidity and mortality worldwide. Some studies have shown that high heat kills cancer cells. Irisin is a protein involved in heat production by converting white into brown adipose tissue, but there is no information about how its expression changes in cancerous tissues. We used irisin antibody immunohistochemistry to investigate changes in irisin expression in gastrointestinal cancers compared to normal tissues. Irisin was found in human brain neuroglial cells, esophageal epithelial cells, esophageal epidermoid carcinoma, esophageal adenocarcinoma and neuroendocrine esophageal carcinoma, gastric glands, gastric adenosquamous carcinoma, gastric neuroendocrine carcinoma, gastric signet ring cell carcinoma, neutrophils in vascular tissues, intestinal glands of colon, colon adenocarcinoma, mucinous colon adenocarcinoma, hepatocytes, hepatocellular carcinoma, islets of Langerhans, exocrine pancreas, acinar cells and interlobular and interlobular ducts of normal pancreas, pancreatic ductal adenocarcinoma, and intra- and interlobular ducts of cancerous pancreatic tissue...

BACKGROUND: Intraductal papillary mucinous neoplasms (IPMN) have been reported to be associated with concurrent, distinct pancreatic ductal adenocarcinoma (con-PDAC) in about 8% (range, 4-10%) of resected branch duct (BD) lesions. In addition, other pancreatic and ampullary tumors are occasionally diagnosed with IPMN in patients undergoing pancreatic surgery. The objective of this study is to describe the prevalence, clinicopathologic characteristics and prognosis of IPMN with concurrent pancreatic and ampullary neoplasms, especially con-PDAC...

Adenosquamous carcinoma of the pancreas (ASCP) is a rare entity. Like adenocarcinoma of the pancreas, overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP...

Primary squamous cell carcinoma (SCC) of the pancreas is a particularly rare entity. Diagnosis of this tumor is tentatively made after ruling out metastatic SCC from another primary site and adenosquamous carcinoma (ASC) of the pancreas. Here we discuss the case of a 76-year-old woman who was found to have a solitary pancreatic lesion and multiple hepatic lesions. Results of computed tomography-guided biopsy of the liver lesions were consistent with a metastatic carcinoma displaying squamous differentiation; therefore, an endoscopic ultrasound (EUS)-guided core-needle biopsy (CNB) of the pancreatic mass was performed...

BACKGROUND: Pancreatic adenosquamous carcinoma (PASC) accounts for only 1-4% of all exocrine pancreatic cancers and carries a particularly poor prognosis. This retrospective study was performed to determine whether inclusion of a platinum agent as part of adjuvant therapy is associated with improved survival in patients with resected PASC. METHODS: Records of all patients who underwent pancreatic resection at Johns Hopkins Hospital from 1986 to 2012 were reviewed to identify those with PASC...

Three sporadic, synchronous, and separate lesions in the ampulla of Vater and the head of the pancreas presented in an 81-year-old male. One was symptomatic and two were incidental. One was detected preoperatively (the ampullary lesion) and two by examination of the resected specimen (the neuroendocrine and pancreatic carcinomas). The case is summarized and the literature and the issue of commonality are reviewed.

Adenosquamous carcinoma rarely occurs in the pancreas, and is characterized by the presence of cellular components from both duct adenocarcinoma and squamous carcinoma. Here, we describe a rare case of pancreatic adenosquamous carcinoma with sarcomatous change. Immunohistochemistry showed that the sarcomatous lesion lost the epithelial marker and aberrantly expressed of acquired mesenchymal markers, which indicated that this special histological phenotype may be attributed to epithelial-mesenchymal transition...

OBJECTIVE: Rapid on-site evaluation (ROSE) of cytologic adequacy improves the diagnostic yield of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). However, on-site advice from a cytotechnologist or cytopathologist is not always available during EUS-FNA. To enhance endosonographers' ability to assess the adequacy of EUS-FNA specimens, we designed an intensive, 2-h interactive training program. The aim of this study was to determine the usefulness of the program. METHODS: Four cytological pictures were selected by a trained cytotechnologist and board-certified cytopathologist from each of the seven patients who underwent EUS-FNA for pancreatic mass in Okayama University Hospital...

OBJECTIVES: Adenosquamous carcinoma of the pancreas (ASC) is a rare malignant neoplasm of the pancreas, exhibiting both glandular and squamous differentiation. However, little is known about its imaging features. This study examined the imaging features of pancreatic ASC. METHODS: We evaluated images of contrast-enhanced computed tomography (CT) and endoscopic ultrasonography (EUS). As controls, solid pancreatic neoplasms matched in a 2:1 ratio to ASC cases for age, sex and tumor location were also evaluated...

Adenosquamous carcinoma of the pancreas is a rare type of pancreatic cancer. Although its molecular biology profile has been shown to be similar to pancreatic ductal adenocarcinoma tumors, it has different prognostic features. There is no consensus or guidelines to treat this tumor differently from pancreatic adenocarcinoma, but therapies based on gemcitabine and platinum chemotherapeutics such as cisplatin and oxaliplatin have been used based on results of a few case reports. We discuss the Abstract #269 from the 2014 ASCO Gastrointestinal Cancers Symposium showing better outcomes from platinum-based therapy in this type of tumors...
