Perioperative blood transfusion is associated with decreased survival in pancreatic, gastric, and liver cancer. The effect of transfusion in adrenocortical carcinoma (ACC) has not been studied. Patients with available transfusion data undergoing curative-intent resection of ACC from 1993 to 2014 at 13 institutions comprising the United States Adrenocortical Carcinoma Group were included. Factors associated with blood transfusion were determined. Primary and secondary end points were recurrence-free survival (RFS) and overall survival (OS), respectively...

The historical approach of diagnosing cancer types based entirely on anatomic origin and histologic features, and the "one-size-fit-all" therapeutic approach, are inadequate in modern cancer treatment. From decades of research we now know that cancer is a highly heterogeneous disease driven by complex genetic or epigenetic alterations. The advent of various high throughput molecular tools has now enabled us to view and sub-classify each cancer type based on their distinct molecular features, in addition to histologic classification, with the promise of individualized treatment strategies tailored towards each specific subtype to improve patient outcomes...

The management of intraductal papillary mucinous neoplasm (IPMN) continues to evolve. In particular, the indications for resection of branch duct IPMN have changed from early resection to more deliberate observation as proposed by the international consensus guidelines of 2006 and 2012. Another guideline proposed by the American Gastroenterological Association in 2015 restricted indications for surgery more stringently and recommended physicians to stop surveillance if no significant change had occurred in a pancreatic cyst after five years of surveillance, or if a patient underwent resection and a non-malignant IPMN was found...

Aberrant DNA methylation patterns are a common theme across all cancer types. Specific DNA demethylation of regulatory sequences can result in upregulation of genes that are critical for tumor development and progression. Integrin α6β4 is highly expressed in pancreatic carcinoma and contributes to cancer progression, in part, through the specific DNA demethylation and upregulation of epidermal growth factor receptor (EGFR) ligands amphiregulin (AREG) and epiregulin (EREG). Whole genome bisulfite sequencing (WGBS) revealed that integrin α6β4 signaling promotes an overall hypomethylated state and site specific DNA demethylation of enhancer elements within the proximal promoters of AREG and EREG...

PURPOSE: We report a very unique case of an esophageal metastasis from a pancreatic ductal adenocarcinoma (PDAC) primary. METHODS: After obtaining consent from the patient, all relevant records of the case were obtained and retrospectively reviewed. RESULTS: At presentation, the patient was diagnosed with synchronous pancreatic and esophageal cancer. He received six months of neoadjuvant therapy including FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and stereotactic body radiation therapy (SBRT) to the pancreatic tumor followed by a combined pancreaticoduodenectomy and Ivor Lewis esophagectomy...

Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells (UCOGC) is currently considered a morphologically and clinically distinct variant of pancreatic ductal adenocarcinoma (PDAC). In this study, we report clinical and pathological features of a series of 22 UCOGC, including the whole exome sequencing of 8 UCOGC. We observed that 60% of the UCOGC contained a well-defined epithelial component and that patients with pure UCOGC had a significantly better prognosis than did those with an UCOGC with an associated epithelial neoplasm...

In pancreatic cancer (PC), adenosquamous carcinoma of the pancreas (PASC) containing both ductal adenocarcinoma and squamous carcinoma in the same tumor represents ~ 4% of the total incidence. To date, the genomic features of this mixed tumor are still unknown. We analyzed genomes of 17 PASCs and 34 ductal adenocarcinomas (PDACs), showing that PASC carried highly enriched TP53 mutations and 3p loss compared to PDAC. Furthermore, we uncovered that adenomatous and squamous components of PASC harbored comparable genomic alterations, suggesting that two cellular components are developed from the same progenitor cancer cells...

Circular RNAs (circRNAs) are a class of long, non-coding RNAs molecules that shape a covalently closed continuous loop which have no 5'-3' polarity and contain no polyA tail. CircRNAs also possess relatively jarless framework and are highly tissue-specific expressed in the eukaryotic transcriptome. Emerging evidences have discovered that thousands of endogenous circRNAs are present in mammalian cells and they mediate gene expression at the transcriptional or post-transcriptional level by binding to microRNAs or other molecules and then inhibit their function...

We conducted a prospective multicenter phase II trial of patients with borderline resectable pancreatic carcinoma to investigate the efficacy of neoadjuvant nab-paclitaxel plus gemcitabine therapy on overall survival (OS). The clinical trial primarily evaluated OS time from the first day of protocol therapy as a primary endpoint. The secondary endpoints were recurrence-free survival from the first day of protocol therapy, safety of the protocol therapy (adverse effect), morbidity based on the Clavien Dindo classification of more than III, response rate, preoperative/postoperative tumor marker (CA 19-9, CEA), rate of normalization, reduction rate of the maximum standardized uptake value on positron emission tomography-computed tomography (limited to institutions where positron emission tomography-computed tomography was available), chemotherapeutic effect grade based on Evans' classification, resection rate, R0 resection rate, surgical data (operative time, blood loss, transfusion, postoperative hospital day), overall morbidity rates (reoperation, rate of readmission, mortality), patient rate in postoperative adjuvant therapy (entry rate, completion rate), dose intensity, quality of life regarding fatigue and malaise assessed by the questionnaire of FACIT-F (Japanese version), and peripheral sensory neuropathy assessed by the questionnaire of the FACT/GOG-NTX subscale (version 4; Japanese version)...

Differential diagnosis based on morphology and immunohistochemistry between a clinically nonfunctioning pituitary neuroendocrine tumor (NET)/pituitary adenoma and a primary or secondary NET of nonpituitary origin in the sellar region may be difficult. Serotonin, a frequently expressed marker in the NETs, has not been systematically evaluated in pituitary NETs. Although mutations in ATRX or DAXX have been reported in a significant proportion of pancreatic NETs, the mutational status of ATRX and DAXX and their possible pathogenetic role in pituitary NETs are unknown...

Pancreatic carcinoma is the fourth leading cause of cancer death and is characterized by early invasion and metastasis. Advances in molecular biology directed new strategies in targeted therapy using monoclonal antibodies. To identify new biomarkers, we generated a panel of monoclonal antibodies against the newly established cell line, Faraz-ICR, from a patient with acinar cell carcinoma. After immunization of BALB/c female mice with Faraz-ICR cell line and fusion of splenocytes with SP2/0 myeloma cell line, high reactive hybridoma producing antibodies to Faraz-ICR were detected using enzyme-linked immunosorbent assay, immunofluorescence staining and flow cytometry...

Doxorubicin is employed alone or in combination for the treatment of several hematological and solid malignancies; despite its efficacy, there are associated cardiotoxicity limits both in its application in patients with heart disease risk factors and also in its long-term use. HFt-MP-PAS40 is a genetically engineered human ferritin heavy chain (HFt)-based construct able to efficiently entrap and deliver doxorubicin to cancer cells. HF-MP-PAS contains a short motif sequence (defined as MP) responsive to proteolytic cleavage by tumor matrix metalloproteases (MMPs), located between each HFt subunit and a masking polypeptide sequence rich in proline (P), alanine (A), and serine (S) residues (PAS)...

Vitamin D has been proposed as a therapeutic strategy in pancreatic cancer, yet evidence for an effect of dietary vitamin D on pancreatic cancer is ambiguous, with conflicting data from human epidemiological and intervention studies. Here, we tested the role of dietary vitamin D in the in vivo context of the well-characterized Ela1-TAg transgenic mouse model of pancreatic acinar cell carcinoma. Through longitudinal magnetic resonance imaging of mice under conditions of either dietary vitamin D deficiency (<5 IU/kg vitamin D) or excess (76,500 IU/kg vitamin D), compared to control diet (1,500 IU/kg vitamin D), we measured the effect of variation of dietary vitamin D on tumor kinetics...

OBJECTIVE: Preliminary work by our group suggested that proteins within the pancreatic cyst fluid (CF) may discriminate degree of IPMN dysplasia. We sought to externally validate these markers and determine whether their inclusion in a preoperative clinical nomogram could increase diagnostic accuracy. SUMMARY BACKGROUND DATA: IPMN is the most common radiographically identifiable precursor to pancreatic cancer; however, the timing and frequency of its malignant progression are unknown, and there are currently no reliable preoperative tests that can determine the grade of dysplasia in IPMN...

BACKGROUND: The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following preconception pancreaticoduodenectomies (Whipple procedures) and chemoradiation to treat pancreatic neoplasms have been reported rarely but none were diagnosed with pre-cancer polycystic ovarian syndrome-associated infertility...
