BACKGROUND: When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions...

There are no standardized diagnostic criteria for intrapancreatic metastasis of pancreatic ductal adenocarcinoma (PDAC). Here, we report two cases of patients with PDAC who were pathologically diagnosed as harboring intrapancreatic metastasis. In both cases, the main lesions were located in the pancreatic body, and no other lesion was detected preoperatively. The patients were diagnosed with pancreatic body cancers and distal pancreatectomy was performed. Pathological findings revealed microscopic cancer nests, which had connections to neither the main lesion nor the premalignant lesion in the pancreatic tail parenchyma...

Purpose: Pancreatic acinar cell carcinoma (ACC) is a rare cancer of the exocrine pancreas. Because of its rare incidence, the efficacy of chemotherapy in this patient population has been largely unknown. Therefore, we retrospectively analyzed the outcomes of patients with advanced pancreatic ACC who received chemotherapy. Materials and Methods: Between January 1997 and March 2015, 15 patients with unresectable or metastatic pancreatic ACC who received systemic chemotherapy were identified in Asan Medical Center, Korea...

Advanced biliary tract cancers (ABTC) are among the deadliest malignancies with limited treatment options after progression on standard-of-care chemotherapy, which includes gemcitabine (GEM) and oxaliplatin (OX). The epidermal growth factor receptor inhibitor erlotinib has been explored in ABTC with modest efficacy. Erlotinib given continuously may antagonize the action of chemotherapy against cycling tumor cells, but pulsatile dosing of erlotinib with chemotherapy may improve efficacy. The purpose of this study was to assess the safety of pulsatile erlotinib with GEMOX...

BACKGROUND: Postchemotherapy retroperitoneal lymphadenectomy (PC-RPLND) represents the treatment of choice in patients with residual masses following chemotherapy for metastatic germ cell tumors. Involvement of major retroperitoneal vessels or thoracic/lumbar spine is rare and challenging but needs complete resection for curative intent. We report on our experience in the management of such complex cases. PATIENTS AND METHODS: A total of 185 patients underwent PC-RPLND and we identified 25 (13...

4T1 metastatic breast cancer model have been widely used to study stage IV human breast cancer. However, the frequent inoculation of a large number of cells, gives rise to fast growing tumors, as well as to a surprisingly low metastatic take rate. The present work aimed at establishing the conditions enabling high metastatic take rate of the triple-negative murine 4T1 syngeneic breast cancer model. An 87% 4T1 tumor incidence was observed when as few as 500 cancer cells were implanted. 4T1 cancer cells colonized primarily the lungs with 100% efficiency, and distant lesions were also commonly identified in the mesentery and pancreas...

INTRODUCTION: Chemo-responsiveness in pancreatic cancer is known to be dependent on fibrosis and vascularity. The purpose of this study was to assess vascular enhancement in advanced pancreatic adenocarcinoma with or without liver metastasis in computed tomography (CT) and to analyze the correlation between enhancement patterns and chemo-responsiveness. METHODS: Patients were assigned to either a responder group (partial response or stable disease) or a non-responder group (progressive disease) according to chemo-responsiveness assessed by CT before and after gemcitabine-based chemotherapy...

: Abnormal tryptophan metabolism via the kynurenine pathway (KP) is involved in the pathophysiology of a variety of human diseases including cancers. α-[(11)C]-methyl-L-tryptophan ((11)C-AMT) positron emission tomography (PET) imaging demonstrated increased tryptophan uptake and trapping in epileptic foci and brain tumors, but the short half-life of (11)C limits its widespread clinical application. Recent in vitro studies suggested that the novel radiotracer 1-(2-[(18)F]fluoroethyl)-L-tryptophan ((18)F-FETrp) may be useful to assess tryptophan metabolism via the KP...

Cancer of the exocrine pancreas is a malignancy with a high lethal rate. Surgical resection is the only possible curative mode of treatment. Metastatic pancreatic cancer is incurable with modest results from the current treatment options. New genomic information could prove treatment efficacy. An independent review of PubMed and ScienceDirect databases was performed up to March 2016, using combinations of terms such pancreatic exocrine cancer, chemotherapy, genomic profile, pancreatic cancer pharmacogenomics, genomics, molecular pancreatic pathogenesis, and targeted therapy...

Pancreatic cancer remains one of the cancers for which survival has not improved substantially in the last few decades. Only 7% of diagnosed patients will survive longer than five years. In order to understand and mimic the microenvironment of pancreatic tumors, we utilized a murine orthotopic model of pancreatic cancer that allows non-invasive imaging of tumor progression in real time. Pancreatic cancer cells expressing green fluorescent protein (PANC-1 GFP) were suspended in basement membrane matrix, high concentration, (e...

INTRODUCTION: Pancreatic metastases are uncommon and only found in a minority of patients with widespread metastatic disease at autopsy. The most common primary cancer site resulting in pancreatic metastases is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma and sarcoma. PRESENTATION OF CASE: Herein, we report a 63-year-old male patient who presented -3.5 years after radical nephrectomy performed for renal cell carcinoma (RCC)-with a well-defined lobular, round mass at the body of the pancreas demonstrated by abdominal Magnetic Resonance Imaging (MRI)...

AIM: Luteinizing hormone releasing hormone (LHRH) is a neurohormone, secreted by the hypothalamus, which regulates the secretion of gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) from the pituitary. LHRH acts by binding to receptors located in the pituitary gland. These receptors (LHRH receptors) have also been found in the cytoplasm of many tumor cells that involve both the reproductive and non-reproductive organs. These receptors have been demonstrated in prostate and breast cancers, endometrial carcinomas, renal cell carcinoma, lymphoma, carcinoma of liver, pancreas and skin...

Effect sizes of efficacy of first-line treatments for (metastatic) pancreas cancer are constrained, underscoring the need for evaluations of the efficacy-to-cost relationship. We critically review economic evaluations of first-line chemotherapy regimens for pancreatic cancer since the 1997 introduction of gemcitabine. We searched PubMed/MEDLINE and EMBASE (1997-2015), and the websites of health technology assessment agencies. Two authors independently reviewed economic studies for eligibility in this review; evaluated peer-reviewed, journal-published studies in terms of the Drummond Checklist; and critiqued the technical and scientific merit of all studies...

Pancreatic cancer is a disease that carries a poor prognosis. Accurate tissue diagnosis is required. Tumours contain a high content of stromal tissue and therefore biopsies may be inconclusive. Circulating tumour cells (CTCs) have been investigated as a potential "liquid biopsy" in several malignancies and have proven to be of prognostic value in breast, prostate and colorectal cancers. They have been detected in patients with localised and metastatic pancreatic cancer with sensitivities ranging from 38%-100% using a variety of platforms...

A 66-year-old woman presented with abdominal discomfort. Contrast-enhanced CT revealed a mass in the pancreas and multiple liver metastases. Pathological examination confirmed the mass to be primary pancreatic cancer. Endoscopic insertion of a biliary stent was performed to prevent common bile duct obstruction. Subsequently, she received combination chemotherapy, which resulted in a complete response. FDG-PET-CT after chemotherapy revealed a high uptake of FDG along the outline of the biliary stent, with complete disappearance of both the primary and metastatic tumors...

Immune checkpoint inhibitor is a verified standard of care as a second-line chemotherapy for non-small cell lung cancer. Management of immune-related adverse effects (irAEs) is crucial for ensuring patient safety. However, less frequent irAEs may result in complications. Here, we report a patient with recurrent lung adenocarcinoma who was treated with nivolumab and developed immune-related pancreatitis. A 66-year-old Japanese female with recurrent lung adenocarcinoma and metastatic lymph nodes presented with anorexia, vomiting, and back pain on day 18 of two cycles of nivolumab...

Pancreas ductal adenocarcinoma lacks predictive biomarkers. CD40 is a member of the tumor necrosis factor superfamily. CD40-sCD40L interaction is considered to contribute to the promotion of tumor cell growth and angiogenesis. The aim of the present study was to investigate the role of serum sCD40L as a predictor in metastatic pancreatic cancer. We evaluated 27 consecutive pancreatic cancer patients treated with FOLFIRINOX (21 patients) or gemcitabine plus nab-paclitaxel combination (six patients). The sCD40L level was measured in serum by enzyme-linked immunosorbent assay at baseline, at first evaluation (all patients), and at time to progression (18 patients)...

Poorly differentiated neuroendocrine tumors are rare but their incidence is rising. High-grade neuroendocrine lung tumors, including small-cell lung cancer, are part of this group. Outside of the lung, they most often arise within the gastrointestinal tract (oesophagus, guts and pancreas) and are called neuroendocrine carcinomas. Due to their rarity, very little is known about neuroendocrine carcinomas of the pancreas and the gastrointestinal tract and few studies have been done. Therefore, most therapeutic recommendations are issued from studies on small-cell lung cancers...

BACKGROUND & AIMS: Pancreatic ductal adenocarcinoma (PDAC) metastasizes to liver at early stages, making this disease highly lethal. Tissue inhibitor of metalloproteinases-1 (TIMP1) creates a metastasis-susceptible environment in the liver. We investigated the role of TIMP1 and its receptor CD63 in metastasis of early-stage pancreatic tumors using mice and human cell lines and tissue samples. METHODS: We obtained liver and plasma samples from patients in Germany with chronic pancreatitis, pancreatic intra-epithelial neoplasia, or PDAC, as well as hepatic stellate cells (HSCs)...
