Abstract
The evaluation of pancreatic lesions, from solid pancreatic masses to pancreatic cysts, remains a clinical challenge. Although cross-sectional imaging remains the cornerstone of the initial evaluation of an indeterminate pancreatic lesion, advances in imaging with the advent of endoscopic ultrasound scan, elastography, contrast-enhanced endoscopic ultrasound scan, and probe-based confocal laser endomicroscopy have allowed us to visualize the pancreas in even higher resolution and diagnose premalignant and malignant lesions of the pancreas with improved accuracy. This report reviews the range of imaging tools currently available to evaluate pancreatic lesions, from solid tumors to pancreatic cysts.

Abstract
To investigate the prognostic value of tumor metabolism measurements on serial 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography and computed tomography scans in patients with locally advanced esophageal cancer undergoing neoadjuvant chemoradiotherapy. Forty-five patients (63 ± 7 years, 6 female) treated with concomitant chemoradiotherapy before surgery were followed up for 24 ± 18 months (range 4-71). Positron emission tomography and computed tomography scans were obtained within 1 week before the start (PET1) and 1 month after the completion of the treatment (PET2). Total body tumor metabolic activity was measured as the sum of the parameters: SUVmax, SUV corrected for lean body mass, and total lesion glycolysis (TLG40/50/70%). Then, delta values for the parameters between PET1 and PET2 were calculated and expressed as percentage of PET1 results. At the time of the analysis, 27 patients were dead and 18 were alive. There was no difference between the 2 groups in terms of age, sex, site of the disease, histology, and the presence/absence of linfonodal metastases (P = NS). Survival random forest analysis (20,000 trees) resulted in an estimate of error rate of 36%. The nonparametric approach identified ΔTLG40 as the most predictive factor of survival (relative importance 100%). Moreover, T (17%), N (5%), and M (5%) stage of the disease, cancer histology (11%), TLG70 (5%) at the end of chemioradioterapy, and ΔTLG(50-70) (17%-5%) were positively associated with patient outcome. The nonparametric analysis confirmed the prognostic importance of some clinical parameters, such as TNM stage and cancer histology. Moreover, ΔTLG resulted to be the most important factor in predicting outcome and should be considered in risk stratification of patients treated with neoadjuvant chemoradiotherapy.

Abstract
Esophageal cancers account for majority of synchronous or metachronous head and neck cancers. This study examined the risk of esophageal cancer following percutaneous endoscopic gastrostomy (PEG) in head and neck cancer patients using the Taiwan National Health Insurance Research Database. From 1997 to 2010, we identified and analyzed 1851 PEG patients and 3702 sex-, age-, and index date-matched controls. After adjusting for esophagitis, esophagus stricture, esophageal reflux, and primary sites, the PEG cohort had a higher adjusted hazard ratio (2.31, 95% confidence interval [CI] = 1.09-4.09) of developing esophageal cancer than the controls. Primary tumors in the oropharynx, hypopharynx, and larynx were associated with higher incidence of esophageal cancer. The adjusted hazard ratios were 1.49 (95% CI = 1.01-1.88), 3.99 (95% CI = 2.76-4.98), and 1.98 (95% CI = 1.11-2.76), respectively. Head and neck cancer patients treated with PEG were associated with a higher risk of developing esophageal cancer, which could be fixed by surgically placed tubes.

Abstract
In this paper, we outline the relationship between the need to put existing applied health research knowledge into practice (the 'know-do gap') and the need to improve the evidence base (the 'know gap') with respect to the healthcare process used for older people with frailty known as comprehensive geriatric assessment (CGA). We explore the reasons for the know-do gap and the principles of how these barriers to implementation might be overcome. We explore how these principles should affect the conduct of applied health research to close the know gap. We propose that impaired flow of knowledge is an important contributory factor in the failure to implement evidence-based practice in CGA; this could be addressed through specific knowledge mobilisation techniques. We describe that implementation failures are also produced by an inadequate evidence base that requires the co-production of research, addressing not only effectiveness but also the feasibility and acceptability of new services, the educational needs of practitioners, the organisational requirements of services, and the contribution made by policy. Only by tackling these issues in concert and appropriate proportion, will the know and know-do gaps for CGA be closed.

Abstract
Prior studies have suggested that a high intake of isoflavonoids is associated with a protective effect against hormone-related cancers, such as colorectal cancer (CRC). Calycosin, a main component of isoflavones, has been shown to suppress the growth of hormone-dependent tumors through an ERβ-mediated signaling pathway. However, the effects of calycosin on CRC remain unclear. In this study, we aimed to investigate the anti-tumor activities of calycosin on CRC and its potential mechanism. HCT-116 cells were treated with calycosin. Cell proliferation, apoptosis and invasiveness were measured by MTT assay, flow cytometry and transwell invasion assay, respectively. mRNA levels of ER beta (ERβ) and miR-17 were quantified by real-time PCR. Protein expressions of ERβ and phosphatase and tensin homolog deleted on chromosome ten (PTEN) were determined by western blotting. We found that calycosin significantly induced apoptosis, and inhibited proliferation and invasiveness of HCT-116 cells in a dose-dependent manner. In addition, ERβ expression significantly increased in calycosin-treated HCT-116 cells, followed by a decrease of miR-17, and up-regulation of PTEN. Our results indicate that calycosin has an inhibitory effect on CRC, which might be obtained by ERβ-mediated regulation of miR-17 and PTEN expression.

Abstract
Peritoneal dissemination is a significant variable affecting long term survival of abdominal cancer patients. A generally accepted clinical point of view is that peritoneal dissemination is tantamount to distant organ metastases. This implies it to be a terminal condition. Current practice dictates that if peritoneal dissemination is observed intraoperatively, the curative therapeutic options are deferred and comprehensive systemic chemotherapy remains the only option with a dismal prognosis. The past few years have generated lot of interest in management of peritoneal carcinomatosis. Prof Paul Sugarbaker has researched, validated and fine-tuned the concept of cytoreductive surgery with peritonectomy procedure (Sugarbaker technique) and perioperative chemotherapy as HIPEC & EPIC. Recognition of a HIPEC centre is based on an infrastructure equipped with basic knowledge of the tumor biology, oncosurgical techniques, technical knowhow for HIPEC administration, intensive care unit etc. There are some aspects which need to be accorded special consideration. Comprehensive therapy of Cytoreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is initiated with exploration and cytoreductive surgery and includes visceral resections and peritonectomy procedure when achieved optimally results in complete, visible resection of all cancer within the abdomen and pelvis. Subsequent to CRS, HIPEC forms an integral part of the surgical procedure. This approach involves conceptual changes in both the route and timing of chemotherapy administration. Patient selection is of utmost importance. The greatest impediment to lasting benefits from intraperitoneal chemotherapy remains an improper patient selection. Currently, there are four important clinical assessments of peritoneal metastasis that need to be used to select patients ie; histopathological type of tumour, radiological distribution of disease, peritoneal cancer index and completeness of cytoreduction. Patients undergoing HIPEC surgery face the usual physiological insults of a major surgery in addition to the thermal stress secondary to intraperitoneal administration of heated chemotherapy agent. A team approach of everyone involved in care of these patients is known to improve patient outcomes. It has also been observed that with the necessary preoperative & perioperative steps, the morbidity and mortality for this treatment can be brought down as comparable to any other major abdominal surgeries.

Abstract
BACKGROUND The role of routine lymphadenectomy for perihilar cholangiocarcinoma is still controversial and no study has defined the minimum number of lymph nodes examined (TNLE). We sought to assess the prognostic performance of American Joint Committee on Cancer/Union Internationale Contre le Cancer (7(th) edition) N stage, lymph node ratio, and log odds (LODDS; logarithm of the ratio between metastatic and nonmetastatic nodes) in patients with perihilar cholangiocarcinoma and identify the optimal TNLE to accurately stage patients. METHODS A multi-institutional database was queried to identify 437 patients who underwent hepatectomy for perihilar cholangiocarcinoma between 1995 and 2014. The prognostic abilities of the lymph node staging systems were assessed using the Harrell's c-index. A Bayesian model was developed to identify the minimum TNLE. RESULTS One hundred and fifty-eight (36.2%) patients had lymph node metastasis. Median TNLE was 3 (interquartile range, 1 to 7). The LODDS had a slightly better prognostic performance than lymph node ratio and American Joint Committee on Cancer, in particular among patients with <4 TNLE (c-index = 0.568). For 2 TNLE, the Bayesian model showed a poor discriminatory ability to distinguish patients with favorable and poor prognosis. When TNLE was >2, the hazard ratio for N1 patients was statistically significant and the hazard ratio for N1 patients increased from 1.51 with 4 TNLE to 2.10 with 10 TNLE. Although the 5-year overall survival of N1 patients was only slightly affected by TNLE, the 5-year overall survival of N0 patients increased significantly with TNLE. CONCLUSIONS Perihilar cholangiocarcinoma patients undergoing radical resection should ideally have at least 4 lymph nodes harvested to be accurately staged. In addition, although LODDS performed better at determining prognosis among patients with <4 TNLE, both lymph node ratio and LODDS outperformed compared with American Joint Committee on Cancer N stage among patients with ≥4 TNLE.

Abstract
Background A detailed evaluation of blood supply anatomy, especially the biliary anatomy at the hepatic hilus, is essential to ensure a complete and curative resection for Bismuth and Corlette type III hilar cholangiocarcinoma. The study aimed to investigate the impact of individualized preoperative planning using 3D modeling on surgical treatment for type III hilar cholangiocarcinoma. Methods This was a retrospective study of patients with type III hilar cholangiocarcinoma (n = 47) who underwent surgery at the Hepatobiliary Surgery Department of Zhujiang Hospital between March 2007 and January 2015. All patients had undergone preoperative computed tomography (CT) examination, and 3D images were reconstructed. Preoperative surgery simulation was performed, and the simulation was applied in the subsequent surgery. Clinical, surgical, and pathological characteristics were compared between patients undergoing preoperative planning (n = 25) and those who did not (n = 22). Complications were examined. Results Surgical time and blood loss were significantly smaller in patients with 3D reconstruction compared to those without. The number of bile duct orifices was correctly estimated in 14/25 (56.0 %) patients with preoperative planning. The width of the hepatic surgical margin could be measured for 18 hepatic ducts, and 17 (68.0 %) of them were pathologically diagnosed as margin-negative. Conclusions This technique has the advantages of precise visualization of the anatomic structures and 3D assessment of biliary branches and vessels, allowing improved operative planning for the treatment of hilar cholangiocarcinoma.

Abstract
The cJun NH2-terminal kinase (JNK) signaling pathway is implicated in the response to metabolic stress. Indeed, it is established that the ubiquitously expressed JNK1 and JNK2 isoforms regulate energy expenditure and insulin resistance. However, the role of the neuron-specific isoform JNK3 is unclear. Here we demonstrate that JNK3 deficiency causes hyperphagia selectively in high fat diet (HFD)-fed mice. JNK3 deficiency in neurons that express the leptin receptor LEPRb was sufficient to cause HFD-dependent hyperphagia. Studies of sub-groups of leptin-responsive neurons demonstrated that JNK3 deficiency in AgRP neurons, but not POMC neurons, was sufficient to cause the hyperphagic response. These effects of JNK3 deficiency were associated with enhanced excitatory signaling by AgRP neurons in HFD-fed mice. JNK3 therefore provides a mechanism that contributes to homeostatic regulation of energy balance in response to metabolic stress. DOI:http://dx.doi.org/10.7554/eLife.10031.001 Consuming the right amount of food is important for health. Eating too little for a long time causes damage to organs, and overeating can cause harm as well, in the form of conditions such as obesity and type 2 diabetes. Several signaling molecules and brain regions are linked to controlling food consumption and ensuring the body receives the correct amount of nutrients to fuel its activities. Previous studies have found that two proteins called JNK1 and JNK2, which are found in most tissues of the body, can reduce how much energy cells use. This can trigger insulin resistance and fat accumulation, and so suggests that blocking the activity of these proteins may help to treat type 2 diabetes and obesity. However, the role of another JNK protein – JNK3, which is mostly found in the brain – was not known. Now, Vernia, Morel et al. have investigated the role of JNK3 in metabolism. It was found that JNK3 reduced the amount of food consumed by mice provided with a cafeteria (high fat) diet. Mice that lacked JNK3 ate far more food and gained more weight on a high fat diet than normal mice. However, JNK3 played no role in food consumption when mice were fed a standard chow diet. Treating normal mice with leptin – an appetite-suppressing hormone – caused them to lose weight, but did not affect mice that lacked JNK3. Examining the brains of the mice revealed that in normal mice, JNK3 in a specific sub-population of neurons decreases the production of proteins that promote eating. However, the proteins continued to be produced in mice that lacked JNK3, encouraging overeating. Overall, the results suggest that blocking the activity of all the JNK proteins will not help treat obesity and diabetes as shutting down JNK3 could encourage overeating. Therefore, future investigation into treatments for these conditions should focus on drugs that specifically target JNK1 and JNK2, and not JNK3. DOI:http://dx.doi.org/10.7554/eLife.10031.002

Abstract
EPB41L3 may play a role as a metastasis suppressor by supporting regular arrangements of actin stress fibres and alleviating the increase in cell motility associated with enhanced metastatic potential. Downregulation of epb41l3 has been observed in many cancers, but the role of this gene in esophageal squamous cell carcinoma (ESCC) remains unclear. Our study aimed to determine the effect of epb41l3 on ESCC cell migration and invasion. We investigated epb41l3 protein expression in tumour and non-tumour tissues by immunohistochemical staining. Expression in the non-neoplastic human esophageal cell line Het-1a and four ESCC cell lines - Kyse150, Kyse510, Kyse450 and Caes17 - was assessed by quantitative Polymerase Chain Reaction (qPCR) and Western blotting. Furthermore, an EPB41L3 overexpression plasmid and EPB41L3-specific small interfering RNA were used to upregulate EPB41L3 expression in Kyse150 cells and to downregulate EPB41L3 expression in Kyse450 cells, respectively. Cell migration and invasion were evaluated by wound healing and transwell assays, respectively. The expression levels of p-AKT, matrix metalloproteinase (MMP)2 and MMP9 were evaluated. Expression of epb41l3 was significantly lower in tumour tissues than in non-tumour tissues and in ESCC cell lines compared with the Het-1a cell line. Kyse450 and Caes17 cells exhibited higher expression of epb41l3 than Kyse150 and Kyse510 cells. Overexpressing epb41l3 decreased Kyse150 cell migration and invasion, whereas EPB41L3-specific small interfering RNA silencing increased these functions in Kyse450 cells. Furthermore, overexpressing epb41l3 led to downregulation of MMP2 and MMP9 in Kyse150 and Kyse510 cells. Our findings reveal that EPB41L3 suppresses tumour cell invasion and inhibits MMP2 and MMP9 expression in ESCC cells.

Abstract
Losing the E-cadherin plays an important role in the metastasis of cancer. The regulation of the expression of E-cadherin is unclear. Circadian rhythm alteration is associated with the pathogenesis of a number of cancers. This study aims to investigate the role of one of the circadian proteins, period-2 (Per2) in repressing the expression of E-cadherin in esophageal cancer (esophageal cancer). We observed that the levels of circadian protein Per2 were significantly increased and E-cadherin was significantly decreased in the tissue of human esophageal cancer with metastasis as compared with non-metastatic esophageal cancer. Overexpression of Per2 in the esophageal cancer cells markedly repressed the expression of E-cadherin. The pHDAC1 was detected in human esophageal cancer with metastasis, which was much less in the esophageal cancer tissue without metastasis. Overexpression of Per2 increased the levels of pHDAC1 as well as the E-cadherin repressors at the E-cadherin promoter locus. Overexpression of Per2 markedly increased the migratory capacity of esophageal cancer cells, which was abolished by the inhibition of HDAC1. We conclude that Per-2 plays an important role in the esophageal cancer cell metastasis, which may be a novel therapeutic target for the treatment of esophageal cancer.

Abstract
OBJECTIVES To determine pathologic features associated with recurrence and survival in patients with lymph node-negative gastric adenocarcinoma. STUDY DESIGN Multi-institutional retrospective analysis. BACKGROUND Lymph node status is among the most important predictors of recurrence after gastrectomy for gastric adenocarcinoma. Pathologic features predictive of recurrence in patients with node-negative disease are less well established. METHODS Patients who underwent curative resection for gastric adenocarcinoma between 2000 and 2012 from 7 institutions of the US Gastric Cancer Collaborative were analyzed, excluding 30-day mortalities and stage IV disease. Competing risks regression and multivariate Cox regression were used to determine pathologic features associated with time to recurrence and overall survival. Differences in cumulative incidence of recurrence were assessed using the Gray method (for univariate nonparametric analyses) and the Fine and Gray method (for multivariate analyses) and shown as subhazard ratios (SHRs) and adjusted subhazard ratios (aSHRs), respectively. RESULTS Of 805 patients who met inclusion criteria, 317 (39%) had node-negative disease, of which 54 (17%) recurred. By 2 and 5 years, 66% and 88% of patients, respectively, experienced recurrence. On multivariate competing risks regression, only T-stage 3 or higher was associated with shorter time to recurrence [aSHR = 2.7; 95% confidence interval (CI), 1.5-5.2]. Multivariate Cox regression showed T-stage 3 or higher [hazard ratio (HR) = 1.8; 95% CI, 1.2-2.8], lymphovascular invasion (HR = 2.2; 95% CI, 1.4-3.4), and signet ring histology (HR = 2.1; 95% CI, 1.2-3.6) to be associated with decreased overall survival. CONCLUSIONS Despite absence of lymph node involvement, patients with T-stage 3 or higher have a significantly shorter time to recurrence. These patients may benefit from more aggressive adjuvant therapy and postoperative surveillance regimens.

Abstract
A 66-year-old male underwent left hemicolectomy for rectal adenocarcinoma in 2008. Five years later he was admitted to hospital with abdominal pain. A computed tomography scan revealed notable thickening of the middle of the ascending colon wall, and colonoscopy revealed an ulcerofungating mass of 3×3 cm in the cecum and extending to the ascending colon. Under the consideration of cancer recurrence, laparoscopic right hemicolectomy was performed directly. Surgical specimens revealed sheets of large pleomorphic lymphoid cells with nuclei of different sizes, nucleoli and mitotic phases visible in most cells. These tested positive for CD45, CD20 and CD79a diffusely, but negative for CD3, CD5, Bcl-2, Bcl-6 and ALK. The Ki-67 proliferation index was 40%. Epstein-Barr virus in situ hybridization did not reveal any positive signals in any of the tumor cells. Based on these findings, the recurrent tumor was diagnosed as diffuse large B-cell lymphoma. The patient could have avoided surgery and received chemotherapy only; however, the case was confounded by the patient's prior history of colorectal cancer due to the rarity of colon lymphoma following rectal cancer in the same patient. It is therefore essential to investigate carefully and differentiate between potential lesions during routine postoperative colonoscopy following colorectal cancer surgery, as patients may present with rare colon lymphoma, which may be confused with a recurrence of colorectal cancer.

Abstract
The management of peritoneal carcinomatosis from colon cancer remains a controversial issue. Peritoneal carcinomatosis is associated with worse survival and has led to an aggressive treatment that combines surgery and intraperitoneal chemotherapy (IPC). This review will describe the rationale behind this treatment and the current controversy surrounding it.

Abstract
PURPOSE The cellular oxidative stress (balance between pro-oxidant and antioxidant) may be a major risk factor for chronic diseases. Antioxidant capacity of human diet can be globally assessed through the dietary non-enzymatic antioxidant capacity (NEAC). Our aim was to investigate the relationship between the NEAC and all-cause and cause-specific mortality, and to test potential interactions with smoking status, a well-known pro-oxidant factor. METHODS Among the French women of the E3N prospective cohort study initiated in 1990, including 4619 deaths among 1,199,011 persons-years of follow-up. A validated dietary history questionnaire assessed usual food intake; NEAC intake was estimated using a food composition table from two different methods: ferric ion reducing antioxidant power (FRAP) and total radical-trapping antioxidant parameter (TRAP). Hazard ratio (HR) estimates and 95 % confidence intervals (CI) were derived from Cox proportional hazards regression models. RESULTS In multivariate analyses, FRAP dietary equivalent intake was inversely associated with mortality from all-causes (HR for the fourth vs. the first quartile: HR4 = 0.75, 95 % CI 0.67, 0.83, p trend < 0.0001), cancer, and cardiovascular diseases. Similar results were obtained with TRAP. There was an interaction between NEAC dietary equivalent intake and smoking status for all-cause and cardiovascular disease mortality, but not cancer mortality (respectively, for FRAP, p inter = 0.002; 0.013; 0.113, results were similar with TRAP), and the association was the strongest among current smokers. CONCLUSION This prospective cohort study highlights the importance of antioxidant consumption for mortality prevention, especially among current smokers.

Abstract
Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) has become a frequently used method in gene expression studies. The relative quantification method is an important and common method for the evaluation of RT-qPCR data. One of the key requirements of this method is to identify an applicable internal reference gene. However, to the best of our knowledge, no suitable reference genes have been identified for the genetic analysis of cholangiocarcinoma (CCA) in humans and cell lines. In the present study, screening was conducted using 12 common reference genes, which were selected in order to provide an experimental basis for the study of the gene expression in CCA patients and cell lines. Tumor samples and adjacent non-neoplastic tissues from 20 patients with CCA were obtained for the present study. The stability and applicability of the 12 reference gene candidates were validated using GeNorm, NormFinder and BestKeeper software. Based on a comparison of the results, the following reference genes are recommended for various tissue groups: Total sample group, ribosomal protein L29; CCA tissue group, TATA-box binding protein; CCA cell line and tissue group, actin-β; CCA cell line group, 18S ribosomal RNA; CCA tissue and adjacent non-neoplastic tissue group, 5'-aminolevulinate synthase 1; and adjacent non-neoplastic tissue group, hypoxanthine phosphoribosyltransferase 1. The results of the search also clearly reveal that a systematic study regarding the selection of suitable reference genes for studying the target gene profiling in CCA tissues and cell lines has not been previously published. The present study may provide useful information for future studies that examine the gene expression of CCA for choosing suitable reference genes.

Abstract
Development of biomarkers that detect early stage resectable premalignant lesions of colon can provide critical aid in the prevention of colorectal cancer. Recent lines of evidence suggest the utility of mucin expression to predict malignant transformation of colon pre-neoplastic lesions. In this study, we investigated the combined expression of multiple mucins and mucin-associated glycans during the adenoma-carcinoma sequence of colon cancer progression. Further, we evaluated their applicability as markers for differentiating adenomas/adenocarcinomas from hyperplastic polyps. Immunohistochemical analyses performed on colon disease tissue microarrays revealed downregulation of MUC2 and MUC4 expression (p < 0.0001) while MUC1 and MUC5AC expressions were upregulated (p = 0.01) during adenoma-adenocarcinoma progression. Expression of MUC17 was downregulated in inflamed tissues compared to normal tissues, but its increased expression differentiated adenomas (p = 0.0028) and adenocarcinomas (p = 0.025) from inflammation. Glycan epitope-Tn/STn on MUC1 showed higher expression in hyperplastic polyps (p = 0.023), adenomas (p = 0.042) and adenocarcinomas (p = 0.0096) compared to normal tissues. Multivariate regression analyses indicated that a combination of MUC2, MUC5AC, and MUC17 could effectively discriminate adenoma-adenocarcinoma from hyperplastic polyps. Altogether, a combined analysis of altered mucins and mucin-associated glycans is a useful approach to distinguish premalignant/malignant lesions of colon from benign polyps.

Abstract
OBJECTIVE To evaluate the possible relationship between serum 25-OH vitamin D levels and visually evoked potentials (VEP) in patients with multiple sclerosis (MS), residents in the south zone of Gran Canaria. MATERIAL AND METHODS The study included 49 patients with MS, on whom 25-OH-vitamin D was determined, along with VEP, and a neurological examination to determine incapacity. Clinical variables, such as a history of optic neuritis were recorded. RESULTS The mean value of 25-OH-vitamin D of the patients was 28.1±9.5ng/ml. The VEP latency was 119.1±23.2ms and the amplitude, 8.5±4.4 μV. Patients with a higher 25-OH-vitamin D had a greater number of outbreaks in the year prior to the study (P=.049), and those with vitamin D deficiency and previous optic neuritis showed no reduction in the amplitude of the VEP (P=.006). CONCLUSION Patients with vitamin D deficiency have lower clinical activity of the MS and show no axonal involvement in VEP after having suffered optic neuritis. These relationships, although statistically significant, do not seem clinically plausible, thus new studies are needed to try and confirm this possible relationship.

Abstract
BACKGROUND Colorectal cancer is the second most common cause of cancer death with half a million deaths per year. Incidence and mortality rates have demonstrated notable changes in Asian and African countries during the last few decades. In this study, we first aimed to determine the trend of colorectal cancer mortality rate in each Institute for Health Metrics and Evaluation (IHME) region, and then re-classify them to find more homogenous classes. MATERIALS AND METHODS Our study population consisted of 52 countries of Asia and North Africa in six IHME pre-defined regions for both genders and age-standardized groups from 1990 to 2010.We first applied simple growth models for pre-defined IHME regions to estimate the intercepts and slopes of mortality rate trends. Then, we clustered the 52 described countries using the latent growth mixture modeling approach for classifying them based on their colorectal mortality rates over time. RESULTS Statistical analysis revealed that males and people in high income Asia pacific and East Asia countries were at greater risk of death from colon and rectum cancer. In addition, South Asia region had the lowest rates of mortality due to this cancer. Simple growth modeling showed that majority of IHME regions had decreasing trend in mortality rate of colorectal cancer. However, re-classification these countries based on their mortality trend using the latent growth mixture model resulted in more homogeneous classes according to colorectal mortality trend. CONCLUSIONS In general, our statistical analyses showed that most Asian and North African countries had upward trend in their colorectal cancer mortality. We therefore urge the health policy makers in these countries to evaluate the causes of growing mortality and study the interventional programs of successful countries in managing the consequences of this cancer.

Abstract
Neuroendocrine tumors of the gastrointestinal tract are rare neoplasms. Rectal neuroendocrine tumors consist approximately the 5%-14% of all neuroendocrine neoplasms in Europe. These tumors are diagnosed in relatively young patients, with a mean age at diagnosis of 56 years. Distant metastases from rectal neuroendocrine tumors are not very common. Herein we describe a case of a rectal neuroendocrine tumor which metastasized to the lung, mediastinum and orbit. This case underscores the importance of early identification and optimal management to improve patient’s prognosis. Therefore, the clinical significance of this case is the necessity of physicians’ awareness and education regarding neuroendocrine tumors’ diagnosis and management.

Abstract
Pyruvate kinase is a key enzyme in the glycolytic pathway that converts phosphoenolpyruvate to pyruvate, and the M2 isoform of pyruvate kinase (PKM2) is associated with cancer. PKM2 has been reported to function independently of its pyruvate kinase activity, which is crucial for cancer cell proliferation. Moreover, there is growing evidence indicating that dimeric PKM2 is released from tumor cells into the circulation of cancer patients. However, the role of secreted PKM2 in cancer is not well understood. Here, we found that the phosphorylation level of epidermal growth factor receptor (EGFR) significantly increased upon the exposure of cells to the recombinant PKM2 protein. In addition, secreted PKM2 induces EGFR phosphorylation and activates the EGFR downstream signaling in triple-negative breast cancer cells. In contrast, knocking down PKM2 decreased EGFR phosphorylation. Moreover, expression of R399E mutant PKM2, which has been reported to preferentially form a dimer, enhanced EGFR phosphorylation, cellular transformation, and cell proliferation more strongly than the wild-type PKM2. Thus, our study revealed a novel function of extracellular PKM2 in the promoting cancer cell proliferation through EGFR activation.

Abstract
Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

Abstract
PURPOSE Radiofrequency identification (RFID) microchips are used to remotely identify objects, e.g. an animal in which a chip is implanted. A passive RFID microchip absorbs energy from an external source and emits a radiofrequency identification signal which is then decoded by a detector. In the present study, we investigated the effect of the radiofrequency energy emitted by a RFID microchip on human cancer cells. MATERIALS AND METHODS Molt-4 leukemia, BT474 breast cancer, and HepG2 hepatic cancer cells were exposed in vitro to RFID microchip-emitted radiofrequency field for 1 h. Cells were counted before and after exposure. Effects of pretreatment with the spin-trap compound N-tert-butyl-alpha-phenylnitrone or the iron-chelator deferoxamine were also investigated. Results We found that the energy effectively killed/retarded the growth of the three different types of cancer cells, and the effect was blocked by the spin-trap compound or the iron-chelator, whereas an inactive microchip and energy from the external source had no significant effect on the cells. Conclusions Data of the present study suggest that radiofrequency field from the microchip affects cancer cells via the Fenton Reaction. Implantation of RFID microchips in tumors may provide a new method for cancer treatment.

Abstract
Ovarian cancer is the leading cause of death for gynecologic cancers, ranking fifth overall for cancer-related death among women. The identification of biomarkers and the elucidation of molecular mechanisms for improving treatment options have received extensive efforts in ovarian cancer research. miRNAs have high potential to act as both ovarian cancer biomarkers and as critical regulators of ovarian tumor behavior. We comprehensively analyzed global mRNA, miRNA expression, and survival data for ovarian cancer from The Cancer Genome Atlas (TCGA) to pinpoint miRNAs that play critical roles in ovarian cancer survival through their effect on mRNA expression. We performed miRNA overexpression and gene knockdown experiments to confirm mechanisms predicted in our bioinformatics approach. We established that overexpression of miR-532-5p in OVCAR-3 cells resulted in a significant decrease in cell viability over a 96-hour time period. In the TCGA ovarian cancer dataset, we found 67 genes whose expression levels were negatively correlated with miR-532-5p expression and correlated with patient survival, such as WNT9A, CSNK2A2, CHD4, and SH3PXD2A The potential miR-532-5p-regulated gene targets were found to be enriched in the Wnt pathway. Overexpression of miR-532-5p through miRNA mimic caused downregulation of CSNK2A2, CHD4, and SH3PXD2A in the OVCAR-3 cell line. We have discovered and validated the tumor-suppressing capabilities of miR-532-5p both in vivo through TCGA analysis and in vitro through ovarian cancer cell lines. Our work highlights the potential clinical importance of miR-532-5p expression in ovarian cancer patients. Mol Cancer Ther; 15(5); 1123-31. ©2016 AACR.

Abstract
The combined treatment concept of cytoreductive surgery (CRS) and Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown to be an efficient therapeutic option for selected patients with primary and secondary peritoneal carcinomatosis (PC). This strategy represents the standard of care for diseases like pseudomyxoma peritonei and peritoneal mesothelioma, and offers the best long-term results for PC from colorectal cancer. Despite these results, skepticism exists regarding this therapeutic approach partly because of its perceived high toxicity. In this article, we review the current evidence on complications that can occur after CRS and HIPEC and the risk factors associated with increased incidence of morbidity and mortality.

Abstract
For the first several years after its development, endoscopic ultrasound (EUS) was primarily limited to identification of pancreatic malignancies. Since this time, the field of EUS has advanced at a tremendous speed in terms of additional clinical diagnostic and therapeutic uses. The combination of ultrasound with endoscopy provides a unique interventional modality that is a minimally invasive alternative to various surgical interventions. Given the expanding recommended indications for EUS, this article will serve to review the most common uses with supporting evidence, while also exploring innovative endeavors that may soon become common clinical practice.

Abstract
Hilar cholangiocarcinoma (HCCA) is an invasive hepatic malignancy that is difficult to biopsy; therefore, novel markers of HCCA prognosis are needed. Here, the level of canonical Wnt activation in patients with HCCA, intrahepatic cholangiocarcinoma (IHCC), and congenital choledochal cysts (CCC) was compared to understand the role of Wnt signaling in HCCA. Pathology specimens from HCCA (n=129), IHCC (n=31), and CCC (n=45) patients were used to construct tissue microarrays. Wnt2, Wnt3, β-catenin, TCF4, c-Myc, and cyclin D1 were detected by immunohistochemistry. Parallel correlation analysis was used to analyze differences in protein levels between the HCCA, IHCC, and CCC groups. Univariate and multivariate analyses were used to determine independent predictors of successful resection and prognosis in the HCCA group. The protein levels of Wnt2, β-catenin, TCF4, c-Myc, and cyclin D1 were significantly higher in HCCA compared to IHHC or CCC. Wnt signaling activation (Wnt2+, Wnt3+, nuclear β-catenin+, nuclear TCF4+) was significantly greater in HCCA tissues than CCC tissues. Univariable analyses indicated that expression of cyclin D1 as well as Wnt signaling activation, and partial Wnt activation (Wnt2+ or Wnt3+ and nuclear β-catenin+ or nuclear TCF4+) predicted successful resection, but only cyclin D1 expression remained significant in multivariable analyses. Only partial Wnt activation was an independent predictor of survival time. Proteins in the canonical Wnt signaling pathway were present at higher levels in HCCA and correlated with tumor resecility and patient prognosis. These results suggest that Wnt pathway analysis may be a useful marker for clinical outcome in HCCA.

Abstract
Peritoneal dissemination is a major cause of recurrence in patients with malignant tumors in the peritoneal cavity. Effective anticancer agents and treatment protocols are necessary to improve outcomes in these patients. However, previous studies using mouse models of peritoneal dissemination have not detected any drug effect against peritoneal micrometastasis. Here we used the luciferase assay to evaluate peritoneal micrometastasis in living animals and established an accurate mouse model of early peritoneal microdissemination to evaluate tumorigenesis and drug efficacy. There was a positive correlation between luminescence intensity in in vivo luciferase assay and the extent of tumor dissemination evaluated by ex vivo luciferase assay and mesenteric weight. This model has advantages over previous models because optimal luciferin concentration without cell damage was validated and peritoneal microdissemination could be quantitatively evaluated. Therefore, it is a useful model to validate peritoneal micrometastasis formation and to evaluate drug efficacy without killing mice.

Abstract
The objective of this research is to develop and validate a sensitive and reproducible UPLC-MS/MS method to quantify irinotecan, its active metabolite SN-38 and SN-38 glucuronide (phase II metabolite of SN-38) simultaneously in different bio-matrices (plasma, urine, feces), tissues (liver and kidney) and to use the method to investigate its pharmacokinetic behavior in rats. Irinotecan, SN-38 and SN-38 glucuronide has been resolved and separated by C18 column using acetonitrile and 0.1% formic acid in water used as the mobile phases. Triple quadruple mass spectrometer using multiple reaction monitoring (MRM) with positive scan mode were employed to perform mass analysis. The results showed that the linear response range of irinotecan and SN-38 in plasma, feces, liver and kidney is 4.88-10000 nM, 39-5000 nM, 48.8-6250 nM and 48.8-6250 nM, respectively (R(2)>0.99). In case of SN-38 glucuronide, the standard curves were linear in the concentration range of 6.25-2000 nM, 4.88-1250 nM, 9.8-1250 nM and 9.8-1250 nM in plasma, feces, liver and kidney homogenates, respectively. The lower limit of detection (LLOD) of irinotecan, SN-38 and SN-38 glucuronide was determined to be less than 25 nM in all bio-matrices as well as tissue homogenates. Recoveries of irinotecan, SN-38 and SN-38 glucuronide at three different concentrations (low, medium and high) were not less than 85% at three different concentrations in plasma and feces. The percentage matrix factors in different bio-matrices and tissues were within 20%. The UPLC-MS/MS method was validated with intra-day and inter-day precision of less than 15% in plasma, feces, liver and kidney. Owing to the high sensitivity of this method, only 20 μl of plasma, urine and homogenates of liver, kidney and feces is needed. The validated method has been successfully employed for pharmacokinetic evaluation of irinotecan in male wistar rats to quantify irinotecan, SN-38 and SN-38 glucuronide in plasma, feces, and urine samples.

Abstract
Purpose Combined modality therapy is a mainstay option for thoracic malignancies and head and neck cancers. The integration of different strategies is based on the multidisciplinary approach of modern clinical oncology. Radiation oncologists have to be educated, trained, and updated to provide state-of-the-art care to cancer patients and thus educational meetings are crucial. Methods The Italian Association of Radiation Oncology Young Members Working Group (AIRO Giovani) organized its 8th national meeting, focused on combination therapy in lung, esophageal, and head and neck cancer (with a specific focus on larynx-preservation strategies for larynx/hypopharynx tumors), involving young professionals working in Italy. The meeting was addressed to young radiation oncologists, presenting state-of-the-art knowledge, based on the latest evidence in this field. We performed a review of the current literature based on the highlights of the Congress. Results The multimodality approach of head and neck and thoracic malignancies includes surgery, chemotherapy, and radiotherapy, but also has to take into account new information and data coming from basic and translational research and including molecular biology, genetics, and immunology. All these aspects are crucial for the treatment of non-small-cell lung cancer and esophageal, esophagogastric junction, and larynx/hypopharynx malignancies. The integration of different treatments in the clinical decision-making process to combine therapies is crucial. Conclusions Combination therapy has proved to be a consolidated approach in these specific oncologic settings, highlighting the importance of multimodality management in modern clinical oncology. Dedicated meetings on specific topics are helpful to improve knowledge and skills of young professionals in radiation oncology.

Abstract
Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined have been recognized as standard of care for treatment of a subset of patients with peritoneal carcinomatosis (PC). The aim of CRS is to eliminate all macroscopic disease through a series of visceral resections followed by targeting any residual microscopic disease with intraperitoneal chemotherapy, exposing the peritoneal surfaces to a high concentration of chemotherapy with a lower systemic toxicity. Different regimes of intraperitoneal chemotherapy include HIPEC, early postoperative intraperitoneal chemotherapy (EPIC) and bidirectional chemotherapy. The efficacy and modality of treatment with intraperitoneal chemotherapy is dependent on multiple factors including the chosen cytotoxic agent and its pharmacokinetics and pharmacodynamics. There is no standardized methodology for intraperitoneal chemotherapy administration. This review will discuss the pharmacological principles of the various intraperitoneal chemotherapy techniques.

Abstract
Peritoneal metastasis, either synchronous or metachronous, is commonly seen in gastric cancer. It is associated with a poor prognosis, with a median survival of less than one year. The outcomes are not significantly improved by the use of systemic chemotherapy. We review the relevant literature on the role of HIPEC in gastric cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used in three situations in gastric cancer. Besides its role as a definitive treatment in patients with established peritoneal metastasis (PM), it has been used as a prophylaxis against peritoneal recurrence after curative surgery and also as a palliative treatment in advanced peritoneal metastasis with intractable ascites. While prophylactic HIPEC has been shown to reduce peritoneal recurrence and improve survival in many randomised trials, palliative HIPEC can reduce the need for frequent paracentesis. Although CRS with HIPEC has shown promise in increasing the survival of selected patients with established PM from gastric cancer, larger studies are needed before this can be accepted as a standard of care.

Abstract
The combined modality treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has gained worldwide acceptance for management of selected patients with peritoneal metastases from various cancers. Cytoreductive surgery is performed with the goal of removing all macroscopic disease and is coupled with perioperative chemotherapy (POC) in the form of HIPEC with or without EPIC (early postoperative intraperitoneal chemotherapy) to deal with the microscopic residual disease. These treatments entail the use of cytotoxic drugs in the operation theatre or in the intensive care unit where they are not commonly used and put the healthcare workers participating in the treatment at risk of exposure. CRS is performed with high voltage electrocautery generating a large amount of surgical smoke which is inhaled by the involved personnel and has potential health hazards. This article outlines the safety measures to be taken while performing CRS and POC.

Abstract
BACKGROUND Accumulating evidence indicates that dysregulated microRNA-146a (miR-146a) is involved in tumour genesis and cancer progression. We aimed to evaluate its expression level and the potential for the diagnosis and prognosis in oesophageal squamous cell cancer (ESCC). METHODS We examined miR-146a expression in 62 pairs of ESCC cancerous and matched paracancerous tissue, 115 formalin-fixed paraffin-embedded (FFPE) tissue samples and serum samples from 154 ESCC patients and 154 healthy volunteers using quantitative reverse transcription-PCR (qRT-PCR). Kaplan-Meier method, Cox regression and receiver-operating characteristic (ROC) curve analysis were applied to analyse its prognostic and diagnostic value. RESULTS MicroRNA-146a expression level was significantly decreased in ESCC tissue compared with paracancerous tissue (P<0.001). Its regulation level was negatively associated with T factor and TNM stage. Kaplan-Meier curve revealed that its downregulation level predicted worse overall survival (OS) and progression-free survival (PFS). Both univariate and multivariate analyses identified miR-146a expression as independent prognostic factor for OS and PFS. Serum miR-146a was significantly reduced in ESCC patients than in healthy controls (P<0.001). Area under the curve ROC value, sensitivity and specificity for this marker were 0.863 ± 0.033, 85.7% and 68.6% in the Discovery Group, and 0.891 ± 0.027, 82.1% and 83.3% in the Validation Group. CONCLUSIONS MicroRNA-146a is significantly reduced in cancerous tissue and serum samples of ESCC patients. It is an ideal biomarker for the prognosis and diagnosis of ESCC.

Abstract
The ampulla of Vater is a complex cellular environment from which adenocarcinomas arise to form a group of histopathologically heterogenous tumors. To evaluate the molecular features of these tumors, 98 ampullary adenocarcinomas were evaluated and compared to 44 distal bile duct and 18 duodenal adenocarcinomas. Genomic analyses revealed mutations in the WNT signaling pathway among half of the patients and in all three adenocarcinomas irrespective of their origin and histological morphology. These tumors were characterized by a high frequency of inactivating mutations of ELF3, a high rate of microsatellite instability, and common focal deletions and amplifications, suggesting common attributes in the molecular pathogenesis are at play in these tumors. The high frequency of WNT pathway activating mutation, coupled with small-molecule inhibitors of β-catenin in clinical trials, suggests future treatment decisions for these patients may be guided by genomic analysis.

Abstract
Although surgery alone represents a curative approach for patients with pT3N0M0 colon cancer, about 15-20% of these patients develop a relapse of disease. Microsatellite instability (MSI) is one of the most important molecular markers in colorectal cancer. The aim of this study was to investigate the prognostic relevance of MSI in all pT3N0M0 tumors recorded in the Cancer Registry of the Province of Modena--(Northern Italy) within the 2002-2006 period in patients who showed a relapse of disease during the 5-year period of follow-up (59 cases). They were compared to 59 controls similar in clinical and pathological features but with good prognosis. None of the subjects received adjuvant chemotherapy. MSI status was tested using BAT25, BAT26, NR24, and CAT25 fluorescent-labeled mononucleotide markers. The overall prevalence of MSI was 12.7% (15 of 118 cases). MSI was detected mainly in mucinous adenocarcinoma (p < 0.003), in high-grade tumors (p < 0.008), in right-sided neoplasms (p < 0.005), and in patients with a better prognosis, though the difference was not statistically significant (11/59 patients -18.6% vs 4/59 patients -6.7%; OR 0.36 CI 95% 0.11-1.15; p = 0.08). However, in multivariate analysis, MSI status becomes the strongest independent factor associated with relapse (OR 0.21, CI 95% 0.06-0.81; p = 0.023), together with mucinous histological type (OR 0.40, CI 90% 0.18-0.92). MSI is a relevant prognostic factor in stage pT3N0M0 colon cancer suitable to discriminate those patients with a high risk of relapse.

Abstract
INTRODUCTION Previous reports showed an excellent survival for patients after resection of pancreatic metastases from renal cell cancer (pRCC) and reported several predictive factors. This study aims to give more evidence to reported risk factors by analyzing a large cohort of patients with pancreatic resection due to pRCC. PATIENTS AND METHODS We retrospectively analyzed all pancreatic resections due to pRCC between January 1993 and October 2014 in two German pancreatic surgery centers. Predictive factors were analyzed using the chi square test. RESULTS Surgery was performed in 40 patients. Mean survival after resection was 147.9 months (SD 25.6 months). No predictive factors for survival were identified. Pathological examination showed that five out of 21 patients with examined peripancreatic lymph nodes had lymph node metastases. CONCLUSIONS Although our analysis comprised the biggest cohort of patients with pRCC it rendered no significant predictor for survival. This might be due to the overall excellent prognosis of study patients and the relatively rare condition with a limited number of patients. Several patients had lymph node metastases. Therefore lymphadenectomy should be considered in pRCC resection if the health condition of the patient permits this. By this more aggressive approach to pRCC, a better prognosis after resection might be achieved.

Abstract
Introduction Peritoneal surface malignancies have long been regarded as incurable, however, they can be treated with cytoreductive surgery in addition to hyperthermic intraperitoneal chemotherapy. This approach is associated with an increase in morbidity and mortality, unless hyperhydration is provided in a timely manner. Methods Cisplatin (CDDP) is the most widely used chemotherapeutic agent. Plasma levels of cisplatin (CDDP), a widely used chemotherapeutic agent, were measured before, during, and after the procedure. This was done in order to identify the window of highest risk as a function of drug concentrations, assuming a dose-dependent effect. Results Plasma levels of CDDP peak during perfusion. The concentration remains high until the 4th post-operative day and returns to pre-operative levels by the 7th post-operative day. Conclusions Our findings suggest that ensuring hyperhydration as well as infusing albumin and fresh frozen plasma may be of particular value for at least the first 4 days after the procedure.
