BACKGROUND AND OBJECTIVES: In patients with borderline resectable pancreas cancers, clinicians frequently consider radiographic response as the primary driver of whether patients should be offered surgical intervention following neoadjuvant therapy (NT). We sought to determine any correlation between radiographic and pathologic response rates following NT. METHODS: Between 2005 and 2015, 38 patients at a tertiary care referral center underwent NT followed by pancreaticoduodenectomy for borderline resectable pancreas cancer...

The International Agency for Research on Cancer (IARC) has classified two liver flukes as carcinogenic to humans (Group 1): Opisthorchis viverrini in 1994 and Clonorchis sinensis in 2009. This review is focused on O. viverrini, the most studied of these two trematodes, which infects nearly 10 million people in Southeast Asia. The life cycle involves two intermediate hosts living in fresh water: a snail of the genus Bithynia and a ciprinid fish. The definitive hosts (human, cat, dog) become infected by ingesting raw fish containing metacercariae, the infective stage of the parasite...

PURPOSE: Pancreatic cancer (PC) is a disease with bad prognosis. It is usually diagnosed at advanced stages and its treatment is complex. The aim of this consensus document was to provide recommendations by experts that would ameliorate PC diagnosis, reduce the time to treatment, and optimize PC management by interdisciplinary teams. METHODS: As a consensus method, we followed the modified Delphi methodology. A scientific committee of experts provided 40 statements that were submitted in two rounds to a panel of 87 specialists of 12 scientific societies...

Diffuse malignant pleural mesothelioma (MPM) is an aggressive tumor that originates from the surface of the pleura. Approximately 70% of cases are associated with chronic asbestos exposure. MPM is regarded as an incurable disease, with a median survival of ~2 years following intensive multimodality treatment. Pancreatic cancer is a malignancy also associated with a poor prognosis, with only 2% of patients surviving for 5 years. The majority of patients with pancreatic cancer are diagnosed with an advanced stage of disease and experience a poor response to therapy...

Among the subsets of tumor-infiltrating lymphocytes (TILs), activated cytotoxic T lymphocytes (granzyme B(+)) have an antitumor effect, while regulatory T lymphocytes [forkhead box P3 (Foxp3)(+)] suppress the antitumor immune response. The aim of the present study was to investigate the possible associations between TIL subsets and survival outcomes in patients with left-sided pancreatic ductal adenocarcinoma (PDAC). From January 2000 to December 2008, 30 patients who underwent curative distal pancreatectomy without neoadjuvant chemoradiotherapy due to left-sided PDAC were enrolled in the present study...

BACKGROUND: Exosomes arise from viable cancer cells and may reflect a different biology than circulating cell-free DNA (cfDNA) shed from dying tissues. We compare exosome-derived DNA (exoDNA) to cfDNA in liquid biopsies of patients with pancreatic ductal adenocarcinoma (PDAC). PATIENTS AND METHODS: Patient samples were obtained between 2003 and 2010, with clinically annotated follow up to 2015. Droplet digital PCR (ddPCR) was performed on exoDNA and cfDNA for sensitive detection of KRAS mutants at codons 12/13...

BACKGROUND: The prognosis for pancreatic cancer remains dismal because many patients are diagnosed with unresectable cancer at the initial diagnosis. Recently, conversion surgery was reported as an effective treatment for initially unresectable pancreatic cancer with a favorable response to non-surgical treatment lasting over 240 days. Here, we describe a case of locally advanced pancreatic cancer (LAPC) successfully resected after treatment with S-1 and radiation followed by gemcitabine/nab-paclitaxel therapy...

A 73-year-old man was referred for F-FDG PET/CT study for staging of biopsy-proven pancreatic adenocarcinoma. The scan demonstrated focal intense FDG uptake in the pancreatic head, localizing the primary tumor. Additional moderate diffuse uptake was seen throughout the pancreas, suggestive of acute pancreatitis. Concurrent diagnostic CT showed diffuse pancreatic hypoenhancement consistent with edema. Serum lipase level was elevated, confirming a diagnosis of acute pancreatitis.

BACKGROUND: Histological features and Ki-67 index have known usefulness in predicting prognosis and guiding therapy among patients with metastatic pancreatic neuroendocrine neoplasms. Fine-needle aspiration may offer advantages for Ki-67 assessment because the technique obtains highly cellular, well-preserved specimens with the potential for broader tumor sampling. In the current study, the authors evaluated concordance for grade and differentiation between concurrent core needle biopsy and cytology preparations...

BACKGROUND: Laparoscopic gastrectomy has become a common surgical treatment for gastric cancer in eastern Asian countries. However, a large-scale prospective study to investigate the benefit of laparoscopy-assisted distal gastrectomy (LADG) regarding long-term outcomes has never been reported. We have already reported the short-term outcomes of this study. Here we report long-term outcomes as the secondary endpoints of this study after a 5-year follow-up period. METHODS: This study comprised patients with clinical stage I gastric cancer who were able to undergo a distal gastrectomy...

BACKGROUND: Published data examining the impact of minimally invasive distal pancreatectomy (MIDP) on survival are generally limited to experiences from high-volume institutions. Our aim was to compare utilization of adjuvant chemoradiation and time from surgery until its initiation following MIDP vs. open surgery (ODP) at a national level. METHODS: Adult patients undergoing distal pancreatectomy for Stage I and II pancreatic adenocarcinoma were identified from the National Cancer Data Base, 2010-2012...

The extent of heterogeneity among driver gene mutations present in naturally occurring metastases-that is, treatment-naive metastatic disease-is largely unknown. To address this issue, we carried out 60× whole-genome sequencing of 26 metastases from four patients with pancreatic cancer. We found that identical mutations in known driver genes were present in every metastatic lesion for each patient studied. Passenger gene mutations, which do not have known or predicted functional consequences, accounted for all intratumoral heterogeneity...

OBJECTIVE: Neoadjuvant protocols for early stage pancreatic adenocarcinoma (PDAC) frequently involve external beam radiation used in combination with systemic chemotherapy. The benefit of radiation in these protocols has not been determined. METHODS: We examined patients with stage I and II PDAC within the National Cancer Data Base between 2006 and 2012. Propensity score matching was used to compare patients receiving neoadjuvant chemotherapy including radiation (NCRT) to those receiving neoadjuvant chemotherapy without radiation (NCT) prior to pancreaticoduodenectomy...

Pancreatic cancer (PC) is an aggressive malady with proclivity for early metastasis. Overexpression of toll-like receptor 4 (TLR4) in pancreatic ductal adenocarcinoma, the most common type of pancreatic malignancy, correlates to tumor size, lymph node involvement, venous invasion and pathological stage. Lipopolysaccharides (LPS) are natural TLR4 ligands that have been shown to increase the invasive ability of PC cells. However, rapid inactivation of circulating LPS and low systemic absorption of inhaled LPS from the bronchoalveolar compartment make other agonists such as saturated fatty acids more suitable to be considered for TLR4-related cell invasiveness...

Endoscopic ultrasound (EUS) has become a mainstay in assisting in the diagnosis and staging of pancreatic cancer. In addition, EUS provides a modality to treat chronic pain through celiac plexus neurolysis. Currently, there is growing data and utilization of EUS in more diverse and innovative applications aimed at providing more sophisticated diagnostic, prognostic and therapeutic options for patients with pancreatic cancer. EUS delivery of chemotherapy, viral and biological vectors and fiducial markers may eventually revolutionize the way clinicians approach the care of a patient with pancreatic cancer...

BACKGROUND: Historically, management of pancreatic cancer has been determined based on whether the tumor was amenable to resection and all patients deemed resectable received curative intent surgery followed by adjuvant therapy with chemotherapy (CT) ± RT. However, patients who undergo resection with microscopic (R1) positive margins have inferior rates of survival. The purpose of this study is to identify patients who have undergone pancreatectomy for pancreatic cancer, determine the surgical margins, types of adjuvant therapies given and patterns of failure...
