- BACKGROUND: To analyze the potential effect of social inequality on pancreatic cancer risk in Western Europe, by reassessing the association within the European Prospective Investigation into Cancer and Nutrition (EPIC) Study, including a larger number of cases and an extended follow-up.METHODS: Data on highest education attained were gathered for 459,170 participants (70% women) from 10 European countries. A relative index of inequality (RII) based on adult education was calculated for comparability across countries and generations. Cox regression models were applied to estimate relative inequality in pancreatic cancer risk, stratifying by age, gender, and center, and adjusting for known pancreatic cancer risk factors.RESULTS: A total of 1,223 incident pancreatic cancer cases were included after a mean follow-up of 13.9 (±4.0) years. An inverse social trend was found in models adjusted for age, sex, and center for both sexes [HR of RII, 1.27; 95% confidence interval (CI), 1.02-1.59], which was also significant among women (HR, 1.42; 95% CI, 1.05-1.92). Further adjusting by smoking intensity, alcohol consumption, body mass index, prevalent diabetes, and physical activity led to an attenuation of the RII risk and loss of statistical significance.CONCLUSIONS: The present reanalysis does not sustain the existence of an independent social inequality influence on pancreatic cancer risk in Western European women and men, using an index based on adult education, the most relevant social indicator linked to individual lifestyles, in a context of very low pancreatic cancer survival from (quasi) universal public health systems.IMPACT: The results do not support an association between education and risk of pancreatic cancer.

- Background: In collaboration with United European Gastroenterology, the working group on ‘Harmonizing diagnosis and treatment of chronic pancreatitis across Europe’ (HaPanEU) developed European guidelines for the management of chronic pancreatitis using an evidence-based approach. Methods: Recommendations of multidisciplinary review groups based on systematic literature reviews to answer predefined clinical questions are summarised. Recommendations are graded using the Grading of Recommendations Assessment, Development and Evaluation system. Results: Recommendations covered topics related to the clinical management of chronic pancreatitis: aetiology, diagnosis of chronic pancreatitis with imaging, diagnosis of pancreatic exocrine insufficiency, surgical therapy, medical therapy, endoscopic therapy, treatment of pancreatic pseudocysts, pancreatic pain, nutrition and malnutrition, diabetes mellitus and the natural course of the disease and quality of life. Conclusions: The HaPanEU/United European Gastroenterology guidelines provide evidence-based recommendations concerning key aspects of the medical and surgical management of chronic pancreatitis based on current available evidence. These recommendations should serve as a reference standard for existing management of the disease and as a guide for future clinical research. This article summarises the HaPanEU recommendations and statements.

- The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori infection and chronic corpus atrophic gastritis. Conditional logistic regression models were applied to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs), adjusted for matching factors and other potential confounders. Our results showed that pancreatic cancer risk was neither associated with H. pylori seropositivity (OR = 0.96; 95% CI: 0.70, 1.31) nor CagA seropositivity (OR = 1.07; 95% CI: 0.77, 1.48). We also did not find any excess risk among individuals seropositive for H. pylori but seronegative for CagA, compared with the group seronegative for both antibodies (OR = 0.94; 95% CI: 0.63, 1.38). However, we found that chronic corpus atrophic gastritis was non-significantly associated with an increased pancreatic cancer risk (OR = 1.35; 95% CI: 0.77, 2.37), and although based on small numbers, the excess risk was particularly marked among individuals seronegative for both H. pylori and CagA (OR = 5.66; 95% CI: 1.59, 20.19, p value for interaction < 0.01). Our findings provided evidence supporting the null association between H. pylori infection and pancreatic cancer risk in western European populations. However, the suggested association between chronic corpus atrophic gastritis and pancreatic cancer risk warrants independent verification in future studies, and, if confirmed, further studies on the underlying mechanisms.

Tidskriftsartikel (refereegranskat)abstract
- Objectives The aim of this study was to study intestinal fatty acid binding protein (i-FABP) as a potential biomarker in predicting severity of acute pancreatitis (AP). Methods In a prospective multicenter cohort study, plasma levels of i-FABP were measured in 402 patients with AP. Severity of AP was determined based on the 1992 Atlanta Classification. Results Admission levels of plasma i-FABP were significantly higher in patients with pancreatic necrosis, in patients having systemic complications, in patients treated invasively, in patients treated in the intensive care unit, in patients with severe AP, and in deceased patients. Plasma i-FABP levels on admission yielded an area under curve (AUC) of 0.732 in discriminating patients with or without pancreatic necrosis and AUC of 0.669 in predicting severe AP. Combination of levels of i-FABP and venous lactate on the day of admission showed higher discriminative power in severe AP - AUC of 0.808. Conclusions Higher i-FABP levels on admission were associated with pancreatic necrosis, systemic complications, and severe AP. Low levels of i-FABP had a high negative predictive value for pancreatic necrosis and severe AP. Combination of levels of i-FABP and venous lactates on admission were superior to either of markers used alone in predicting severe AP.

- Neutrophils are involved in development of acute pancreatitis (AP), but it is not clear how neutrophil-induced tissue damage is regulated. In addition to secreting antimicrobial compounds, activated neutrophils eliminate invading microorganisms by expelling nuclear DNA and histones to form extracellular web-like structures called neutrophil extracellular traps (NETs). However, NETs have been reported contribute to organ dysfunction in patients with infectious diseases. We investigated whether NETs contribute to development of AP in mice.

Irreversible electroporation of pancreatic adenocarcinoma
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Pancreatic cancer (PC) is a severe diagnosis with poor prognosis. Radical surgery is the only treatment that can possibly lead to a cure, and even with surgery, the 5-year survival is only 20%–25%. The majority of patients cannot be resected due to metastases or having a tumour that is too advanced locally (LAPC) with encasement of blood-vessels.Short electrical pulses can change the cell membrane, creating reversible pores in it. With a higher current, the pores become permanent, resulting in irreversible electroporation (IRE). This leads to specific cell death, with the chance to save surrounding scaffold material, such as the walls of blood vessels and bile ducts. This led to the theory that IRE might be suitable for treating LAPC.In Paper I, we found that IRE can be safely performed percutaneously with ultrasound guidance in humans with PC, with promising efficacy, since one of the five patients included was downstaged due to the IRE and could be surgically resected. In Paper II, which is an extension of Paper I, we treated 24 patients with LAPC (3 were also included in Paper I) who had received chemotherapy and, after IRE, stable disease was seen. Median overall survival was 17.9 months. Eleven patients had some form of complication, but we still concluded that IRE is reasonably safe in LAPC patients, with promising efficacy. In Paper III, we chose to treat LAPC with IRE followed by adjuvant chemotherapy. We compared the overall survival of our patients with those with LAPC in the National Quality Registry for Pancreatic and Periampullary Cancer. No significant survival gain could be seen in the group that received IRE compared to the registry group (13.3 months versus 9.9 months, p=0.511). In the IRE group, there were six major complications and we found no support for using IRE in this setting. Paper IV examines the response on the tumour marker CA19-9 in PC treated with IRE. We found 35 patients suitable for this analysis. The hypothesis that IRE would lower the CA19-9 value could not be proven. In fact, the CA19-9 was slightly higher one month after IRE (282 U/ml versus 315 U/ml). However, the 25th percentile of patients with the best CA19-9 response had a better survival (p=0.01) compared to the 25th percentile with the worst response, indicating that CA19-9 can be used as a prognostic marker after IRE in PC.

Tidskriftsartikel (refereegranskat)abstract
- Background The revised Atlanta classification on acute pancreatitis (AP) presents distinct criteria for severity categorization. Due to the lack of reliable prognostic markers, a majority of patients with AP are currently hospitalized and initially managed identically. As incidence and financial costs are rising the need for early severity differentiation will increase. This study aimed to investigate the capacity of biomarkers to stratify AP patients during the initial course of the disease. Methods Patients with AP were prospectively enrolled and dichotomized into mild or non-mild (moderately severe and severe AP) according to the revised Atlanta classification. Serum samples taken within 13–36 h after onset of disease were analyzed for 20 biomarkers. Through receiver operating curves cut-off levels were set for 5 biomarkers whose stratifying ability was further analyzed. Additionally, the patients were classified according to the harmless acute pancreatitis score (HAPS). Results Among the 175 patients, 70.9% had mild and 29.1% non-mild AP. CRP and IL-6 combined, with cut-off levels 57.0 and 23.6 respectively, demonstrated superior discriminative capacity with an area under the curve of 0.803, sensitivity 98%, specificity 54% and a positive and negative likelihood ratio of 2.1 and 0.06 for the non-mild group. Regarding the mild group likelihood ratios were positive 26.5 and negative 0.48. The identification potential of the HAPS was generally inferior when compared to CRP plus IL-6. Conclusions In this study CRP and IL-6 demonstrate a clinically relevant capacity to differentiate mild from non-mild AP early in the course of AP.

- Background: Acute pancreatitis (AP) is a frequent disorder with considerable morbidity and mortality. Obesity has previously been reported to influence disease severity. Objective: The aim of this study was to investigate the association of adipose and muscle parameters with the severity grade of AP. Methods: In total 454 patients were recruited. The first contrast-enhanced computed tomography of each patient was reviewed for adipose and muscle tissue parameters at L3 level. Associations with disease severity were analysed through logistic regression analysis. The predictive capacity of the parameters was investigated using receiver operating characteristic (ROC) curves. Results: No distinct variation was found between the AP severity groups in either adipose tissue parameters (visceral adipose tissue and subcutaneous adipose tissue) or visceral muscle ratio. However, muscle mass and mean muscle attenuation differed significantly with p-values of 0.037 and 0.003 respectively. In multivariate analysis, low muscle attenuation was associated with severe AP with an odds ratio of 4.09 (95% confidence intervals: 1.61–10.36, p-value 0.003). No body parameter presented sufficient predictive capability in ROC-curve analysis. Conclusions: Our results demonstrate that a low muscle attenuation level is associated with an increased risk of severe AP. Future prospective studies will help identify the underlying mechanisms and characterise the influence of body composition parameters on AP.
