However, as suicidal

Fedratinib purchase thoughts and behaviours may still occur in individuals we would still recommend that patients who are started on an antidepressant should be monitored for the emergence of suicidal thoughts in line with good medical practice and the summary of product characteristics. Figure 2. Emergence of suicidal ideation in adults during treatment for depression with selective serotonin reuptake Inhibitors,research,lifescience,medical inhibitors (SSRIs), venlafaxine and placebo [Entsuah et al. 2001]. Inherent toxicity of an antidepressant in overdose One way of assessing the inherent toxicity of a drug in overdose is to calculate case fatality rates. This method compares the rate of death from self-poisoning with the rate of non-fatal self-poisoning; that is, the proportion of people who die from overdose of a particular agent [Rose and Unis, 2000]. In a recent study case fatality indices were calculated for venlafaxine, TCAs and SSRIs using Inhibitors,research,lifescience,medical mortality rates and self-poisoning rates from three centres in the UK [Hawton

et al. 2010]. Relative toxicity indices were calculated by standardizing the rate ratios to amitriptyline. The case fatality (mortality to self-poisoning ratio) for venlafaxine was found to be 2.5 (95% CI Inhibitors,research,lifescience,medical 2.0–3.1), for SSRIs 0.5 (95% CI 0.4–0.7) and for TCAs 13.8 (95% CI 13.0–14.7). The relative toxicity index to amitriptyline was reported as 0.29 for venlafaxine, 0.06 for SSRIs and 1.6 for all TCAs. Therefore, the case fatality rate for venlafaxine was found to be substantially lower than that for TCAs but still greater than that for SSRI antidepressants. However, the authors listed several possible limitations of these data which may have inflated the case fatality rates for venlafaxine. First, nonfatal self-poisonings

not presenting to the Inhibitors,research,lifescience,medical hospitals could not be accounted for and therefore case fatality rates may be overestimated, although this probably applies equally to all drugs in the study. In addition, size of overdose was not considered and the indication for which the antidepressant was prescribed was not taken into account. This may affect case fatality rates if some drugs are used more frequently Inhibitors,research,lifescience,medical for conditions for which lower doses are often prescribed and overdoses may therefore be smaller. Venlafaxine has been previously demonstrated to be preferentially prescribed to patients with longer-term to psychiatric disorders and a history of self-harm [Bergen et al. 2010; Chan et al. 2010; Mines et al. 2005] and therefore it is conceivable that this fact may increase the case fatality rate for venlafaxine in this particular study relative to SSRIs if larger overdoses are taken. However, it should be noted that there is currently no direct evidence that patients take larger venlafaxine quantities. In addition, data from the Edinburgh Poisons Unit indicate that admissions due to citalopram, mirtazapine or venlafaxine overdose involved around 15–16 times the defined daily dose for all three agents [Waring et al. 2010].

Figure 3 Time course (x-axis) of the hemodynamic responses in reading aloud for irregular words (A) and nonwords (B) for one female participant (F. M.). The y-axis indicates relative changes in concentration (from −1 × 10−06 to 5 × … For this participant (F. M.), [HbO] and [HbT] values increased immediately after initiating

the reading task, and gradually reached their peak at about 6 sec in the occipital regions bilaterally. In the frontotemporal regions bilaterally, [HbO] and [HbT] reached their peak concentrations at around 17 sec. When the participant stopped reading, [HbO] Inhibitors,research,lifescience,medical and [HbT] levels showed a rapid decline and gradually returned to their baseline. This pattern of increase was sustained for [HbR] albeit with a much smaller amplitude than [HbO]. Inhibitors,research,lifescience,medical We also found that [HbO] concentrations were higher in the left than the right hemisphere in the frontotemporal regions. Hemodynamic changes were analogous for irregular word and nonword reading.

All participants showed similar patterns of hemodynamic responses except for B. B., who showed the reverse pattern. In this participant, we recorded a Inhibitors,research,lifescience,medical decrease in [HbO] and an increase in [HbR] concentrations in all regions but the bilateral occipital regions. We observed Inhibitors,research,lifescience,medical in another participant (J. T.) a right lateralization of reading in the frontotemporal regions with higher [HbO] concentrations in the right than the left hemisphere, for both irregular words and nonwords. In irregular word reading, we found that the maximum peak of activation for [HbO] in all

12 participants occurred at about 8 sec in the bilateral occipital Inhibitors,research,lifescience,medical selleck kinase inhibitor cortices, at about 12 sec in the bilateral temporal regions, and finally at about 14.5 sec in the bilateral frontal regions. In nonword reading, the maximum peak of activation we observed for the 12 participants occurred also at approximately 8 sec in the bilateral occipital cortices, but at about 13 sec in the bilateral frontal regions and approximately 14 sec in the bilateral temporal regions, in contrast with irregular word reading. Spatial distribution of the significant hemodynamic responses We performed a two-tailed paired t-test Electron transport chain for each participant (t(12) > 2.17, P < 0.05, uncorrected) to determine the cerebral regions in which [HbT] concentrations in reading tasks were significantly different from those measured at rest (10-sec duration before the beginning of the reading tasks). [HbT] was chosen as the dependent variable because it correlates with cerebral blood flow. The regions were fitted on a segmented Brodmann Atlas template.

Finding reliable markers heralding

Finding reliable markers heralding schizophrenia and applying them toward prevention Despite the undisputable evidence that the degree of relatedness of an individual to another individual already affected by schizophrenia increases the risk of Selleck Linifanib manifesting the illness, most individuals diagnosed with the disease do not have an affected relative. Furthermore, the concordance among monozygotic twins is <50 %. Taken together, these points indicate a genetic contribution

to the illness, but rule out the possibility of simple mendelian inheritance and underscore the environmental contribution. Inhibitors,research,lifescience,medical To explain the mode of inheritance of this illness, as well as the delayed and very heterogeneous manifestation, it was hypothesized that multiple susceptibility genes interact with environmental influences. However, before such a hypothesis can be validated, major obstacles Inhibitors,research,lifescience,medical have to be overcome. The first obstacle is in the realm of identifying multiple susceptibility genes acting

additively or multiplicatively to affect brain function by modulating neural development and neurotransmitters and hence the corresponding brain microcircuits.13 This task is particularly daunting since each gene probably confers a small risk or protective effect (no more Inhibitors,research,lifescience,medical than threefold) and, at the same time, could modulate the effects of other susceptibility genes. Hence, it is likely that more than one constellation of genes Inhibitors,research,lifescience,medical will act together to produce susceptibility to the same particular behavior, emotion, or pattern of thinking. Similarly, the same genetic constellation could have different behavioral manifestations depending on environmental interactions. Even after genes conferring susceptibility for psychosis have been identified, it is still essential to determine how the Inhibitors,research,lifescience,medical specific gene product (protein or enzyme) affects neural transmission and

brain circuits, and translate these effects into welldefined emotions, behaviors, and cognitive functioning (or phenotype). Despite these obstacles, some biological markers associated with schizophrenia have been identified, such as met/val substitution on the catecholamine O-methyl transferase gene (COMT), which accounts for a small part of the cognitive impairment among some schizophrenia patients. More important, however, is the observation that the malfunction in COMT, an enzyme affecting dopamine metabolism, can be conceptually placed on the etiological pathway before to the illness, which gives the finding a biological plausibility. Furthermore, despite the fact that markers like the COMT abnormality explain only a negligible fraction of the vulnerability for schizophrenia, such findings open the way to decompose the schizophrenic syndrome into biological subcategories with corresponding clinical manifestations. Thus, keeping the prevention paradigm in mind, it could be plausible to intervene pharmacologically in future patients and in their nonaffected first-degree relatives who carry the mutation.

This may allow true advances in the development of new markers of malignant potential. Haese and colleagues11 examined the TMPRSS2-ERG gene fusion and its relationship to pathology at radical prostatectomy. They used a urine assay to quantitate the TMPRSS2- ERG fusion. Among 74 men, 38% had non-organ-confined disease and 93% had Gleason score ≥ 7. The gene fusion level was significantly higher in men with non-organ-confined disease and those with Gleason score 7 versus 6. [Michael K. Brawer, MD] Prostate Cancer Prostate cancer screening was a major theme at #OSI-027 molecular weight keyword# the 2011 AUA meeting. There

is now randomized evidence that PSA screening reduces prostate cancer mortality for men aged 50 to 69 years.12,13 However, prior studies have suggested high rates of screening in elderly men with limited life expectancies who are unlikely to benefit.14 A new report from Gupta and colleagues examined rates of PSA screening in men from the Behavioral Risk Factor Surveillance System survey Inhibitors,research,lifescience,medical (2001–2008).15 Inhibitors,research,lifescience,medical They found that men in their 70s were more likely to undergo screening than men aged 40 to 60 years, and that approximately 60% of men aged ≥ 80 years had a PSA test in the past year. These results suggest continued overutilization of screening in elderly men, as well as potential underutilization of baseline

PSA testing at a younger age. Indeed, prior studies have shown that PSA levels at a young age are associated with

the risk of prostate cancer and aggressive disease.16,17 Vickers and colleagues presented new data from the Malmo Preventive Project in Sweden, in which a Inhibitors,research,lifescience,medical single PSA measurement at age 44 to 50 years predicted disease-specific mortality at a median follow-up of 27 years.1 In this study, 44% of all later prostate cancer deaths occurred in men with PSA levels in the top 10% at age 44 to 50 Inhibitors,research,lifescience,medical (> 1.5 ng/mL), indicating a high-risk population for whom careful follow-up is necessary. Another controversy is the appropriate age to discontinue screening. One recent study suggested that men with a PSA level < 1 ng/mL at age 60 years do Ketanserin not require further PSA testing given the low risk of metastasis and death in this patient subset.18 In a new analysis from the Baltimore Longitudinal Study of Aging, Loeb and Colleagues19 similarly reported a low overall risk of prostate cancer (6.5%) among men with an initial PSA < 1 ng/ mL in their 60s; however, 30.8% of these cases were life threatening. Moreover, despite starting out with a PSA<1 ng/mL, the subsequent PSA trajectory differed substantially between men without prostate cancer compared with those later diagnosed with non-high-risk and, particularly, high-risk disease. Thus, additional PSA measurements would have identified high-risk cases. However, the optimal number and timing of additional PSA screening require further study.

We have previously shown that two consecutive substitutions leade

We have previously shown that two consecutive substitutions leaded to consecutive nonsense mutations in the BMPR1A gene in our proband’s family (21). The severity of disease in this family seemed more pronounced than in many others with germline BMPR1A mutations, as two affected individuals developed colon cancer, and one had gastric juvenile polyps, both of which are more check details common in JP patients with SMAD4 rather than BMPR1A mutations (22,23). Our case also contradicts previous studies in the sense that JPS is an autosomal dominant disorder, and inheritance of a single deleterious

allele is sufficient to cause the JP phenotype (21). Apart from their academic significance, genetic Inhibitors,research,lifescience,medical examinations are crucial in identifying children who are carriers but have no symptoms. In any case, a paradigm shift is indeed needed for autosomal dominantly inherited diseases such Inhibitors,research,lifescience,medical as JPS. Hamartomatous polyps are not benign lesions; thus, we need to provide more advanced carcinoma-prevention by endoscopy, invasive endoscopy, or

surgical methods which may give these patients the opportunity for a better quality life with a longer life-span.

Esophageal cancer is diagnosed in about 400,000 patients each year worldwide, and its incidence is increasing Inhibitors,research,lifescience,medical (1), it is the sixth leading cause of death from cancer (2). In

Europe, while incidence of SCC has remained stable or declined during the past few decades, the incidence of esophageal adenocarcinoma has been rising. This increase has been more prominent in Northern Europe, notably in the United Kingdom and Ireland (3,4). The majority of the patients suffering from a cancer Inhibitors,research,lifescience,medical of the esophagus presents with symptoms of dysphagia and weight loss because of an obstructive tumor (5). Several management options have been developed to palliate malignant dysphagia. These include endoluminal stenting Edoxaban or surgery and external beam radiation, brachytherapy, chemotherapy, chemoradiotherapy, laser treatment, photodynamic therapy or ablation using injection of alcohol or chemotherapeutic agents (6-8). Placement of self-expanding metallic stents (SEMS) made up of an alloy, usually nitinol or stainless steel, and deployed using endoscopic or fluoroscopic techniques, is a newer method for relief of dysphagia in these patients (9). External beam radiotherapy (EBRT) is known to provide durable and effective relief of dysphagia. However, there is a time lag before symptomatic relief occurs, and up to 6 weeks are required for maximum benefit (8).

Next, the initial release rate (at t = 0) is used to estimate kS

Next, the initial release rate (at t = 0) is used to estimate kS. Last, koff that determines the kinetics of the sustained release is calculated. These estimated parameters (i.e., ΔG, kS, koff) are used as the initial input in Matlab codes to refine the estimations using an optimization Alvespimycin research buy method. The properties of the parameter estimates, such as mean and standard deviation, are assessed using bootstrap sampling [28], as detailed Inhibitors,research,lifescience,medical in Section 3.5. 3.2. Drug Release from Liposomes and Nanocapsules Liposomes and lipid nanocapsules (LNC) are among drug delivery systems that first made their way to clinical applications [5]. The bilayered structure of liposomes enables the encapsulation of hydrophilic

and lipophilic drug in their interior aqueous compartments (Figure 1(b)) and in the lipid bilayers (Figure 1(c)), respectively [32]. However, liposomes can be easily trapped by the reticuloendothelial system (RES), leading to rapid removal from circulation [33]. A hydrophilic barrier, often formed by polyethylene glycol (PEG) derivatives, Inhibitors,research,lifescience,medical may be created to protect liposomes, avoiding their uptake Inhibitors,research,lifescience,medical by RES [34]. PEGylation of liposomes increased their circulation half-times of about 30 minutes to 5 hours nearly two decades ago [34] to around 10 hours

recently [35], enhancing their spontaneous accumulation in solid tumors [34, 36]. Efforts to control release kinetics made it possible to deplete encapsulated drugs in a time comparable to or longer than the circulation time of liposomes [25, 26]. Here, we simulate drug release Inhibitors,research,lifescience,medical from liposomes and LNC at different time scales (Figures 3(a)–3(d)) and from polymeric

nanocapsules (NC) for comparison (Figures 3(e) and 3(f)). Parameter estimates for the Inhibitors,research,lifescience,medical simulations are listed in Table 1. Table 1 Parameter estimates for simulations in Figure 3. We first simulate the fast release of CF from TSL, triggered by mild hyperthermia (Figure 3(a)). Li et al. [24] designed and synthesized TSL such that its gel-to-liquid transition temperature resided at around 43°C. As a result, TSL was stable at 37°C and capable of retaining encapsulated molecules in the circulation. Once it reached the targeted site, TSL released encapsulated molecules rapidly due to and the gel-to-liquid transition induced by local hyperthermia. This process can be modulated by PEG addition. For instance, TSL with a high PEG density releases CF faster than TSL with a low PEG density. Our model successfully captures CF release from TSL with different PEG densities at 42°C. In particular, both ΔG and kS increase with PEG density, suggesting that PEGylation not only modifies the permeability of the lipid membrane but also decreases the ability of TSL to interact with hydrophilic molecules. This is consistent with the report [24] that PEG at a high density destabilizes the lipid membrane of TSL and changes the membrane modality for CF release.

Both COMT, as a catecholamine catabolizing enzyme, and the DA tr

Both COMT, as a catecholamine catabolizing enzyme, and the DA transporter, DAT1, work together to clear extracellular DA from the synaptic cleft. In doing so, they

regulate synaptic DA concentrations in the brain mainly in cortical and subcortical regions. A contribution of both the COMT and the DAT1 polymorphisms to the activity of the DA system and an interaction (epistasis effect) of these genes is quite likely, at least from a pharmacological Inhibitors,research,lifescience,medical viewpoint. In humans, the COMT gene contains a functional nonsynonymous single nucleotide polymorphism (SNP), a guanine to adenine transition in codon 158 of the COMT gene located at the q11 band of human chromosome 22 (rs#4680). The substitution of the amino acid Val by Met results in decreased thermostability of the protein leading to Inhibitors,research,lifescience,medical a three- to fourfold AR-A014418 mw reduced COMT enzyme activity at physiologically relevant temperatures. The COMT alleles are codominant with three genotypes possible: carriers of the Val/Val genotype have highest, carriers of the Met/Met genotype have lowest, and heterozygotes (Val/Met genotype) have intermediate levels of COMT enzyme activity (Lachman et al. 1996; Chen et al. 2004; Weinshilboum et al. 1999). Consistently, the number of Met alleles is positively related to prefrontal DA levels (Tunbridge et al. 2006). The involvement of the COMT Val158Met polymorphism in emotional processing is supported by numerous association studies relating

the Met Inhibitors,research,lifescience,medical allele or the Met/Met Inhibitors,research,lifescience,medical genotype to anxiety disorders (Enoch et al. 2003; Domschke et al. 2004; McGrath et al. 2004; Woo et al. 2004; Olsson et al. 2005; Montag et al. 2008), anxiety-related traits including high neuroticism, and low sensation seeking and low extraversion (Reuter and Hennig 2005; Stein et al. 2005; Lang et al. 2007) and obsessive-compulsive disorder (Pooley et al. 2007). A diminished stress resilience and emotional regulation for the Met allele (Goldman et al. 2005) is in line with an association with increased pain sensitivity (Zubieta et al. 2003). In addition, Inhibitors,research,lifescience,medical the Met allele is associated

with the onset of mood disorders after exposure to adverse life events (Mandelli et al. 2007). These findings suggest that the COMT Val158Met polymorphism and especially the Met/Met genotype leads to increased predisposition to emotional Ribonucleotide reductase disorders, with anxiety and depression as the most common ones. However, it must be noted that despite of this high convergent validity that relates the Met allele to NEM and the Val allele to PEM, there are also some studies reporting conflicting results. The human dopamine transporter (DAT1/SLC6A3) gene localized on chromosome 5p15.3 contains a 40 base pair (bp) variable number of tandem repeats (VNTR) polymorphism in its 3′-untranslated region (3′UTR) with repeat numbers ranging from 3 to 11. The two most frequent alleles in the population are the nine- and 10-repeat (9R and 10R) alleles (Vandenbergh et al. 1992).

5 Australia and New Zealand have national recommendations stating

5 Australia and New Zealand have national recommendations stating that all perinatal providers have the responsibility to be aware of the risks for perinatal depression and to identify and refer for selleck chemical treatment as indicated.6 In Norway, the government has endorsed an initiative to address mental health issues for women during pregnancy and

after childbirth.7 In the US, further evidence of support for perinatal depression was the 2010 passage of the Melanie Blocker Stokes MOTHERS Act, one component of the 2010 US Patient Protection and Affordable Care Act (PPACA). Inhibitors,research,lifescience,medical The MOTHERS act established a comprehensive federal commitment to combat postpartum depression through research, education, and voluntary

support service programs. However, although Inhibitors,research,lifescience,medical considerable progress has been made in terms of increasing public awareness, there remain many critically important unanswered questions and gaps in our understanding about perinatal depression. For example, there is still much to be learned about the underlying pathogenesis, the long-term impact of perinatal depression Inhibitors,research,lifescience,medical on the developing fetus, and how best to counsel pregnant women about the risks of untreated MDD versus the risks of psychopharmacologic treatment during pregnancy and lactation. This review will discuss these important issues and describe currently recommended Inhibitors,research,lifescience,medical treatment options based on the available literature. Epidemiology of perinatal depression Many good quality studies have documented that perinatal depression is both common and morbid. 1,2,8-10 Estimates of prevalence are about 12% in the general population, but higher in individuals from certain groups including those with a prior history of MDD and in those with a history of PPD.2,10 In addition, an increased prevalence has also been noted in low-income women, which disproportionately Inhibitors,research,lifescience,medical affects ethnic minorities, particularly

African-American and Hispanic women in the US.11,12 Moreover, the perinatal period has been documented already to be a time of high risk for psychiatric hospitalization, particularly in women with bipolar affective disorder and those with past histories of MDD.13 Most importantly, the risk for maternal suicide is significantly elevated among depressed perinatal women, and maternal suicides account for up to 20% of all postpartum deaths, making it one of the leading causes of maternal mortality in the perinatal period.14 Perinatal depression can have devastating consequences for the affected woman, her children, and family,15-18 and has been linked to poor childbirth outcomes such as preterm delivery and low birth weight19,20 and to detrimental effects on maternal sensitivity in the postpartum period.

80 These older agents appear as effective as more recent antidepressant agents.83 However, the widespread use of these agents is limited by their relatively unfavorable side-effect profile, including problematic anticholinergic and antiadrenergic effects,84 and they are not recommended as first-line agents.8-11 Similarly, while classic monoamine oxidase inhibitors (MAOIs) may be

effective for panic disorder, they are not commonly prescribed for this indication. These agents exert their antidepressant effect by inhibiting the MAO enzyme, so decreasing the breakdown Inhibitors,research,lifescience,medical of serotonin and noradrenaline and increasing the net level of these neurotransmitters in the CNS.15 However, Inhibitors,research,lifescience,medical as is the case with TCAs, the widespread use of MAOIs is generally limited by their associated adverse effects (including the risk of hypertensive crisis when taken with tyramine-containing foods) and their numerous potential drug interactions. Alprazolam, a short-acting agent, is the best studied benzodiazepine in panic disorder.80 It has shown efficacy compared with placebo in short and longer-term studies, and it has been found comparable in effect to the tricyclics

and to the Inhibitors,research,lifescience,medical SSRIs.85 Alprazolam as well as a number of other benzodiazepines (clonazepam, diazepam, and lorazepam) are FDA-approved for PD.15 Nevertheless, once again, given their relatively unfavorable Inhibitors,research,lifescience,medical side-effect profile, most treatment guidelines do not list these agents as a first-line option.8-11 Fluoxetine, paroxetine, and sertraline have all been rigorously investigated in clinical trials and have received

FDA approval for use in PD.15 They are as effective, but better tolerated, than the older TCAs.83 There seems to be little difference in efficacy within this group of agents.80 Current guidelines recommend that active medication be continued for at least a year, in order to prevent relapse and optimize outcome.8-11 There is partial evidence that SNRIs Inhibitors,research,lifescience,medical and other newer TG101348 antidepressants are effective in PD.80 On the one hand, relatively few of these agents have been well studied in PD, not all findings have been consistently positive, and concerns have also been raised about the safety profile of certain agents (eg, venlafaxine) in comparison with the SSRIs.85 Rebamipide On the other hand, there is some evidence that more noradrenergic antidepressants may be of benefit in PD patients who have failed to respond to serotonergic antidepressants.86 Thus SNRIs and some other newer antidepressants (for example, mirtazapine and reboxetine) can be considered as a treatment option in the pharmacotherapy of PD:87 There is also some evidence of the efficacy of other classes of agent in panic disorder. In particular, anticonvulsant agents have been investigated for use.

5% vs. 40% p=0.005). Conclusion While resection of pancreatic cancer can be performed with low perioperative mortality, the associated perioperative morbidity can be significant. Recent advances in surgical instrumentation have made wide spread adoption of laparoscopic distal

pancreatectomy possible. Similar to experience in other cancer types, the initial oncologic outcome with laparoscopic distal pancreatectomy appear comparable to open distal pancreatectomy. The advantage of minimally invasive surgery in terms of less blood loss and shorter hospital stay was also Inhibitors,research,lifescience,medical observed. The advances in surgical techniques also allow more aggressive surgical resection to be Inhibitors,research,lifescience,medical performed with acceptable perioperative mortality and morbidity. With the advances

in systemic treatment of pancreatic cancer, the ability to achieve negative resection margin will improve the outcome of patients with this aggressive disease. Footnotes No potential conflict of interest.
Adenocarcinoma of pancreas is the fourth Inhibitors,research,lifescience,medical most common cause of cancer-related death among U.S. men and women. Due to lack of specific symptoms and effective screening modality, about 80% of pancreatic cancer cases are diagnosed at advanced stage with locally advanced or metastatic disease. Surgical resection remains the only curative therapy for pancreatic cancer patients, and 5-year survival for surgically resected patients is only 30%. Therefore, more research and novel strategies are urgently needed to understand biology better, detect the selleck compound disease sooner, Inhibitors,research,lifescience,medical and develop better treatment to improve survival and quality of life. In this focused issue, we have covered important topics related to biology, detection and treatment of pancreatic cancer. Inhibitors,research,lifescience,medical Imaging modality is important to identify patients at risk for pancreatic cancer. With the advance of imaging modality and technique, there has been significant improvement in identifying smaller tumor in pancreas. At present time, only about 15-20%

of patients have resectable disease at the time of diagnosis. Preoperative staging to assess the extent of disease is critical to select patients for complete (R0) resection. Besides distant metastasis, lesions involving superior mesenteric artery and/or celiac axis are generally considered unresectable. Pre-operative evaluation with computed tomography and other modality PD184352 (CI-1040) such as endoscopic ultrasound can better select patients for R0 resection. Tummala et al. have reviewed different imaging modalities and their utility in assessing patients with suspicious pancreatic lesion, and identifying unresectable disease in patients with pancreatic cancer (1). The improvement in perioperative care and surgical techniques has led to decrease in mortality and morbidity for patients receiving resection of pancreatic cancer.
