ABSTRACT: Rare truncating BRCA2 K3326X (rs11571833) and pathogenic CHEK2 I157T (rs17879961) variants have previously been implicated in familial pancreatic ductal adenocarcinoma (PDAC), but not in sporadic cases. The effect of both mutations in important DNA repair genes on sporadic PDAC risk may shed light on the genetic architecture of this disease. Both mutations were genotyped in germline DNA from 2,935 sporadic PDAC cases and 5,626 control subjects within the PANcreatic Disease ReseArch (PANDoRA) consortium. Risk estimates were evaluated using multivariate unconditional logistic regression with adjustment for possible confounders such as sex, age and country of origin. Statistical analyses were two-sided with p values <0.05 considered significant. K3326X and I157T were associated with increased risk of developing sporadic PDAC (odds ratio (OR

2 Article Antimicrobial Peptide Human Neutrophil Peptide 1 as a Potential Link Between Chronic Inflammation and Ductal Adenocarcinoma of the Pancreas. 2018

Pausch, Thomas / Adolph, Sarah / Felix, Klaus / Bauer, Andrea S / Bergmann, Frank / Werner, Jens / Hartwig, Werner. · ·Pancreas · Pubmed #29683978.

ABSTRACT: OBJECTIVES: Defensins are antimicrobial peptides playing a role in innate immunity, in epithelial cell regeneration, and in carcinogenesis of inflammation-triggered malignancies. We analyzed this role in pancreatic ductal adenocarcinoma (PDAC) in the context of its association with chronic pancreatitis (CP). METHODS: Human tissue of healthy pancreas, CP, and PDAC was screened for defensins by immunohistochemistry. Defensin α 1 (human neutrophil peptide 1 [HNP-1]) expression was validated using mass spectrometry and microarray analysis. Human neutrophil peptide 1 expression and influences of proinflammatory cytokines (tumor necrosis factor α, interleukin 1β, and interferon γ) were studied in human pancreatic cancer cells (Colo 357, T3M4, PANC-1) and normal human pancreatic duct epithelial cells (HPDE). RESULTS: Accumulation of HNP-1 in malignant pancreatic ductal epithelia was seen. Spectrometry showed increased expression of HNP-1 in CP and even more in PDAC. At RNA level, no significant regulation was found. In cancer cells, HNP-1 expression was significantly higher than in HPDE. Proinflammatory cytokines significantly led to increased HNP-1 levels in culture supernatants and decreased levels in lysates of cancer cells. In HPDE cytokines significantly decreased HNP-1 levels. CONCLUSIONS: Inflammatory regulation of HNP-1 in PDAC tissue and cells indicates that HNP-1 may be a link between chronic inflammation and malignant transformation in the pancreas.

3 Article Incidence, risk factors and clinical implications of chyle leak after pancreatic surgery. 2017

Strobel, O / Brangs, S / Hinz, U / Pausch, T / Hüttner, F J / Diener, M K / Schneider, L / Hackert, T / Büchler, M W. ·Department of General, Visceral and Transplantation Surgery, Heidelberg University Hospital, Im Neuenheimer Feld 110, 69120, Heidelberg, Germany. ·Br J Surg · Pubmed #27763684.

ABSTRACT: BACKGROUND: Chyle leak is a well known but poorly characterized complication after pancreatic surgery. Available data on incidence, risk factors and clinical significance of chyle leak are highly heterogeneous. METHODS: For this cohort study all patients who underwent pancreatic surgery between January 2008 and December 2012 were identified from a prospective database. Chyle leak was defined as any drainage output with triglyceride content of 110 mg/dl or more. Risk factors for chyle leak were assessed by univariable and multivariable analyses. The clinical relevance of chyle leak was evaluated using hospital stay and resolution by 14 days for short-term outcome and overall survival for long-term outcome. RESULTS: Chyle leak developed in 346 (10·4 per cent) of 3324 patients. Pre-existing diabetes, resection for malignancy, distal pancreatectomy, duration of surgery 180 min or longer, and concomitant pancreatic fistula or abscess were independent risk factors for chyle leak. Both isolated chyle leak and coincidental chyle leak (with other intra-abdominal complications) were associated with prolonged hospital stay. Some 178 (87·7 per cent) of 203 isolated chyle leaks and 90 (70·3 per cent) of 128 coincidental chyle leaks resolved with conservative management within 14 days. Initial and maximum drainage volumes were associated with duration of hospital stay and success of therapy by 14 days. Impact on survival was restricted to chyle leaks that persisted at 14 days in patients with cancer undergoing palliative surgery. CONCLUSION: Chyle leak is a relevant complication, with an incidence of more than 10 per cent after pancreatic surgery, and has a major impact on hospital stay. Drainage volume is associated with hospital stay and success of therapy.

4 Article Postoperative pancreatic fistula: We need to redefine grades B and C. 2016

Hackert, Thilo / Hinz, Ulf / Pausch, Thomas / Fesenbeck, Irina / Strobel, Oliver / Schneider, Lutz / Fritz, Stefan / Büchler, Markus W. ·Department of Surgery, University of Heidelberg, Heidelberg, Germany. · Department of Surgery, University of Heidelberg, Heidelberg, Germany.

ABSTRACT: BACKGROUND: Postoperative pancreatic fistula (POPF) is the most important complication after pancreatic surgery. In 2005, the International Study Group of Pancreatic Surgery (ISGPS) introduced a standardized POPF definition with severity grading from A to C. In recent years, interventional drainage (ID) has become the standard of care for symptomatic postoperative fluid collections or undrained POPF. From the original definition, it is unclear whether ID is categorized as POPF grade B or C. Therefore, international authors shift ID between grades B and C. The aim of the study was to analyze patients with ID (proposed new grade B) versus patients who underwent reoperation (grade C) for POPF. METHODS: Between 2005 and 2013, all patients undergoing pancreatic resection were analyzed regarding POPF grade A-C. Demographic data, type of operation, postoperative complications, therapies and outcome were examined with focus on ID versus reoperation. RESULTS: Of the 2,955 patients included, 403 developed POPF (13.6%). Among all POPF, 11% were grade A, 17% grade B (clinically symptomatic without ID), and 72% grade C. These patients underwent either ID (n = 165) or reoperation (n = 123). Patients with ID had an average hospital stay of 33 days and POPF-associated mortality of 0%. This was strikingly different from patients undergoing reoperation with a hospital stay of 47 days and POPF-associated mortality of 37% (P < .0001). CONCLUSION: After 10 years of the ISGPS classification, there is a clear-cut outcome difference between patients undergoing POPF-associated ID or reoperation. We propose assigning all patients undergoing ID as POPF grade B. Patients undergoing reoperation should definitely remain within category C.

5 Article Cachexia but not obesity worsens the postoperative outcome after pancreatoduodenectomy in pancreatic cancer. 2012

Pausch, Thomas / Hartwig, Werner / Hinz, Ulf / Swolana, Thomas / Bundy, Bogota D / Hackert, Thilo / Grenacher, Lars / Büchler, Markus W / Werner, Jens. ·Department of General Surgery, University of Heidelberg, Germany. ·Surgery · Pubmed #22770957.

ABSTRACT: BACKGROUND: Prognosis after pancreatoduodenectomy for pancreatic cancer is determined by tumor characteristics, completeness of resection, and patient's comorbidity. Our aim was to assess the effects of body mass and fat distribution on the postoperative course after pancreatoduodenectomy. METHODS: Of 2,968 pancreatic resections, 408 patients with primary pancreatic adenocarcinoma who underwent pancreatoduodenectomy and of whom cross sectional images were available were identified and followed-up in a prospective database. Preoperative computed tomographic or magnetic resonance imaging scans were analyzed for abdominal wall fat, hip girdle fat, visceral fat, and abdominal depth. Peri- and postoperative parameters, including preoperative unintentional weight loss, cachexia-associated serum parameters, nonoperative and operative complications, and mortality and long-term survival were evaluated and correlated with body mass index and fat distribution. RESULTS: Patients with low body mass index had a greater 90-day mortality (P = .048) and a trend toward greater complication rates and in-hospital mortality, despite a greater comorbidity in obese patients with a higher body mass index. Accordingly, patients with large amounts of abdominal wall fat had fewer intra-abdominal abscesses (P = .047), lower in-hospital (P = .019) and 90-day mortality rates (P = .007), and better long-term survival (P = .016). CONCLUSION: In pancreatic cancer, underweight but not obese patients have a poor outcome after pancreatoduodenectomy. This observation emphasizes the need for pre- and perioperative therapeutic improvements in the setting of pancreatic cancer-associated cachexia.

6 Article Neutrophil granulocyte derived MMP-9 is a VEGF independent functional component of the angiogenic switch in pancreatic ductal adenocarcinoma. 2011

Bausch, Dirk / Pausch, Thomas / Krauss, Tobias / Hopt, Ulrich Theodor / Fernandez-del-Castillo, Carlos / Warshaw, Andrew L / Thayer, Sarah P / Keck, Tobias. ·Department of General and Visceral Surgery, University of Freiburg, Germany. ·Angiogenesis · Pubmed #21442180.

ABSTRACT: BACKGROUND: Vascular endothelial growth factor (VEGF) that is secreted by tumor cells plays a key role in angiogenesis. Matrix metalloproteinase 9 (MMP-9) is produced by inflammatory cells, such as stromal granulocytes (PMN), remodels the extracellular matrix and is known to promote angiogenesis indirectly by interacting with VEGF. The aim of this study was to determine the role of PMN-derived MMP-9, its interaction with VEGF, and the efficacy of anti-angiogenic therapy targeting MMP-9 with oral Doxycycline and VEGF with Bevacizumab in pancreatic cancer (PDAC). METHODOLOGY/PRINCIPAL FINDINGS: Inhibitors to MMP-9 (Doxycycline) and VEGF (Bevacizumab) were used alone or in combination in an in vitro angiogenesis assay to test their effect on angiogenesis caused by MMP-9, VEGF, PMN and PDAC cells. In an in vivo model of xenografted PDAC, treatment effects after 14 days under monotherapy with oral Doxycycline or Bevacizumab and a combination of both were evaluated. In vitro, PMN-derived MMP-9 had a direct and strong proangiogenic effect that was independent and additive to PDAC-derived VEGF. Complete inhibition of angiogenesis required the inhibition of VEGF and MMP-9. In vivo, co-localization of MMP-9, PMN and vasculature was observed. MMP inhibition with oral Doxycycline alone resulted in a significant decrease in PDAC growth and mean vascular density comparable to VEGF inhibition alone. CONCLUSIONS/SIGNIFICANCE: PMN derived MMP-9 acts as a potent, direct and VEGF independent angiogenic factor in the context of PDAC. MMP-9 inhibition is as effective as VEGF inhibition. Targeting MMP-9 in addition to VEGF is therefore likely to be important for successful anti-angiogenic treatment in pancreatic cancer.
