ABSTRACT: BACKGROUND: The MDACC group recommends to extend the current borderline classification for pancreatic cancer into three groups: type A patients with resectable/borderline tumor anatomy, type B with resectable/borderline resectable tumor anatomy and clinical findings suspicious for extrapancreatic disease and type C with borderline resectable and marginal performance status/severe pre-existing comorbidity profile or age>80. This study intents to evaluate the proposed borderline classification system in a multicenter patient cohort without neoadjuvant treatment. METHODS: Evaluation was based on a multicenter database of pancreatic cancer patients undergoing surgery from 2005 to 2016 (n = 1020). Complications were classified based on the Clavien-Dindo classification. χ RESULTS: Most patients (55.1%) were assigned as type A patients, followed by type C (35.8%) and type B patients (9.1%). Neither the complication rate, nor the mortality rate revealed a correlation to any subgroup. Type B patients had a significant worse progression free (p < 0.001) and overall survival (p = 0.005). Type B classification was identified as an independent prognostic marker for progression free survival (p = 0.005, HR 1.47). CONCLUSION: The evaluation of the proposed classification in a cohort without neoadjuvant treatment did not justify an additional medical borderline subgroup. A new subgroup based on prognostic borderline patients might be the main target group for neoadjuvant protocols in future.

3 Article Blood fibrinogen levels discriminate low- and high-risk intraductal papillary mucinous neoplasms (IPMNs). 2017

ABSTRACT: BACKROUND: The risk assessment of intraductal papillary mucinous neoplasms (IPMN) to either guide patients to surgical resection or watchful waiting is still under debate. Additional markers to better separate low and high-risk lesions would improve patient selection. METHODS: Patients who underwent pancreatic resections for IPMNs between January 2008 and December 2012 with available blood samples were selected and retrospectively assessed. Data on cyst characteristics such as cyst size, duct relation and main-duct dilatation were collected and plasma fibrinogen levels were measured. RESULTS: A total of 73 patients fulfilled the inclusion criteria by pancreatic resection for pathologically confirmed IPMN and available blood sample. Histologically, IPMNs were classified as low-grade and borderline in 52 (71.2%, group 1) and as high-grade and invasive in 21 (28.8%, group 2) of all cases. Fibrinogen levels showed significant differences between the two groups (group 1: mean 3.62 g/L (SD ± 1.14); group 2: mean 4.49 g/L (SD ± 1.57); p = 0.027). A ROC-curve analysis calculated cut-off value of 4.71 g/L separated groups 1 and 2 (p = 0.008). Fibrinogen levels remained as the only significant factor in multivariable analysis, cyst size and duct relation were not significant. CONCLUSION: Blood fibrinogen differed between low and high risk IPMNs and therefore, the use of fibrinogen as an additional discriminator in the pre-operative risk assessment of IPMNs should be further evaluated.

4 Article VEGFR-2, CXCR-2 and PAR-1 germline polymorphisms as predictors of survival in pancreatic carcinoma. 2013

Uzunoglu, F G / Kolbe, J / Wikman, H / Güngör, C / Bohn, B A / Nentwich, M F / Reeh, M / König, A M / Bockhorn, M / Kutup, A / Mann, O / Izbicki, J R / Vashist, Y K. ·Department of General, Visceral and Thoracic Surgery, University Medical Center of Hamburg-Eppendorf, Martinistr. 52, 20246Hamburg, Germany. vashist@uke.de ·Ann Oncol · Pubmed #23293110.

ABSTRACT: BACKGROUND: Hypoxic environment of pancreatic cancer (PC) implicates high vascular in-growth, which may be influenced by angiogenesis-related germline polymorphisms. Our purpose was to evaluate polymorphisms of vascular endothelial growth factor receptor 2 (VEGFR-2), CXC chemokine receptor 2 (CXCR-2), proteinase-activated receptor 1 (PAR-1) and endostatin (ES) as prognostic markers for disease-free (DFS) and overall survival (OS) in PC. PATIENTS AND METHODS: Genotyping of 173 patients, surgically treated for PC between 2004 and 2011, was carried out by TaqMan(®) genotyping assays or polymerase chain reaction. Chi-square test, Kaplan-Meier estimator and Cox regression hazard model were used to assess the prognostic value of selected polymorphisms. RESULTS: VEGFR-2 -906 T/T and PAR-1 -506 Del/Del genotypes predicted longer DFS (P = 0.003, P = 0.014) and OS (VEGFR-2 -906, P = 0.011). CXCR-2 +1208 T/T genotype was a negative predictor for DFS (P < 0.0001). Combined analysis for DFS and OS indicated that patients with the fewest number of favorable genotypes simultaneously present (VEGFR-2 -906 T/T, CXCR-2 +1208 C/T or C/C and PAR-1 -506 Del/Del) were at the highest risk for recurrence or death (P < 0.0001). CONCLUSION: VEGFR-2 -906 C>T, CXCR-2 +1208 C>T and PAR-1 -506 Ins/Del polymorphisms are potential predictors for survival in PC.

5 Article Arterial en bloc resection for pancreatic carcinoma. 2011

ABSTRACT: BACKGROUND: Surgery for locally advanced pancreatic cancer with arterial involvement of the hepatic artery, coeliac trunk and superior mesenteric artery (SMA) is highly controversial. In a retrospective review, the benefits and harms of arterial en bloc resection (AEBR) for pancreatic adenocarcinoma with arterial involvement were analysed. METHODS: Patients were divided into three groups: 29 patients who had pancreatic resection and AEBR (group 1), 449 who had pancreatic resection with no arterial resection or reconstruction (group 2), and 40 with unresectable tumours who underwent palliative bypass (group 3). RESULTS: Eighteen patients underwent reconstruction of the hepatic artery, eight of the coeliac trunk and three of the SMA. Additional reconstruction of portal vein was required in 15 patients and of adjacent visceral organs in 19. Perioperative morbidity and mortality rates were higher in group 1 than in group 2 (P = 0·031 and P = 0·037 respectively). Additional portal vein resection was an independent predictor of morbidity (P < 0·001). Median overall survival was similar for groups 1 and 2 (14·0 versus 15·8 months; P = 0·152), and lower for group 3 (7·5 months; P = 0·028 versus group 1). CONCLUSION: In selected patients AEBR can result in overall survival comparable to that obtained with standard resection and better than that after palliative bypass. Nevertheless, AEBR is associated with significantly higher morbidity and mortality rates, counterbalancing the overall gain in survival and limiting the overall oncological benefit.
