ABSTRACT: Progress in the diagnostics and therapy of gastro-entero-pancreatic (GEP) neuroendocrine neoplasms (NEN), the published results of new randomised clinical trials, and the new guidelines issued by the European Neuroendocrine Tumour Society (ENETS) have led the Polish Network of Neuroendocrine Tumours to update the 2013 guidelines regarding management of these neoplasms. We present the general recommendations for the management of NENs, developed by experts during the Third Round Table Conference - Diagnostics and therapy of gastro-entero-pancreatic neuroendocrine neoplasms: Polish recommendations in view of current European recommenda-tions, which took place in December 2016 in Żelechów near Warsaw. Drawing from the extensive experience of centres dealing with this type of neoplasms, we hope that we have managed to develop the optimal management system, applying the most recent achievements in the field of medicine, for these patients, and that it can be implemented effectively in Poland. These management guidelines have been arranged in the following order: gastric and duodenal NENs (including gastrinoma); pancreatic NENs; NENs of the small intestine and appendix, and colorectal NENs.

ABSTRACT: This article presents updated diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine tumours (PNEN), proposed by the Polish Network of Neuroendocrine Tumours. The guidelines contain new data received in the years 2013-2016, which confirm previous recommendations, and have led to modification of previous guidelines or have resulted in the formulation of new guidelines. Biochemical and imaging (anatomical and functional) tests are of great importance in diagnostics, as well as histopathological diagnosis to determine the management of PNEN patients, but they must be confirmed by an immunohistochemical examination. PNEN therapy requires collaboration among the members a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment in many cases. Further therapy requires a multidirectional procedure; therefore, the rules of biotherapy, peptide receptor radionuclide therapy, molecular targeted therapy, and chemotherapy are discussed.

4 Guideline Pancreatic neuroendocrine neoplasms - management guidelines (recommended by the Polish Network of Neuroendocrine Tumours). 2013

Kos-Kudła, Beata / Hubalewska-Dydejczyk, Alicja / Kuśnierz, Katarzyna / Lampe, Paweł / Marek, Bogdan / Nasierowska-Guttmejer, Anna / Nowakowska-Duława, Ewa / Pilch-Kowalczyk, Joanna / Sowa-Staszczak, Anna / Rosiek, Violetta / Anonymous7490781 / Anonymous7500781. ·Division of Endocrinology, Department of Pathophysiology and Endocrinology, Medical University of Silesia, Katowice, Poland. endoklin@sum.edu.pl. ·Endokrynol Pol · Pubmed #24431118.

ABSTRACT: We present revised diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine neoplasms (PNENs) proposed by the Polish Network of Neuroendocrine Tumours.These guidelines refer to biochemical (determination of specific and nonspecific neuroendocrine markers) and imaging diagnostics (EUS, CT, MR, and radioisotope examination with a 68Ga or 99Tc labelled somatostatin analogue).A histopathological diagnostic, which determines the further management of patients with PNENs, must be necessarily confirmed by immunohistochemical tests. PNENs therapy requires collaboration between a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment. Medical therapy requires a multidirectional procedure, and therefore the rules of biotherapy, peptide receptor radionuclide therapy, chemotherapy and molecular targeted therapy are discussed.

5 Review Intraductal oncocytic papillary neoplasms of the pancreas and bile ducts: a description of five new cases and review based on a systematic survey of the literature. 2010

Liszka, Lukasz / Pajak, Jacek / Zielińska-Pajak, Ewa / Krzych, Lukasz / Gołka, Dariusz / Mrowiec, Sławomir / Lampe, Paweł. ·Department of Histopathology, Medical University of Silesia, ul. Medyków 18, 40-754, Katowice, Poland. LLISZKA@MP.PL ·J Hepatobiliary Pancreat Sci · Pubmed #20464560.

ABSTRACT: BACKGROUND: Intraductal oncocytic papillary neoplasms (IOPN) are rare tumors of the pancreatic and biliary ductal system. It is not absolutely clear if the molecular and clinicopathologic characteristics of IOPN differ significantly from other related lesions, namely intraductal papillary mucinous neoplasms (IPMN). Therefore it is not clear if it is reasonable to consider IOPN as a separate diagnostic and clinical entity. METHODS: In order to describe the clinicopathologic characteristics of IOPN and to compare them with the IPMN profile, we performed a systematic review of the literature and additionally studied five previously unreported IOPN cases. RESULTS: IOPN differ from IPMN by lack of K-ras gene mutations in all studied cases. Several differences in the clinical and biological profile between IOPN and IPMN exist, but they are of quantitative rather than of qualitative nature. Additionally, pancreaticobiliary or gastric-foveolar IPMN components may coexist with IOPN component within a single lesion, which suggests at least a partial relation of the pathogenetic pathways of IPMN and IOPN. Importantly, the pathogenesis of accumulation of mitochondria and oxyphilic appearance of IOPN remains unknown. CONCLUSIONS: At present, there are no reliable criteria other than histopathological picture and K-ras gene status to differentiate IOPN from IPMN. In particular, no clear differences in optimal treatment options and prognosis between these tumors are known. Further studies are needed to clarify the biology of IOPN and to establish their position in clinicopathologic classifications of pancreatic tumors.

6 Clinical Trial A nickel-titanium memory-shape device for gastrojejunostomy: comparison of the compression anastomosis clip and a hand-sewn anastomosis. 2014

Kusnierz, Katarzyna / Lekston, Zdzislaw / Zhavoronkov, Dmytro / Mrowiec, Slawomir / Lampe, Pawel. ·Department of Gastrointestinal Surgery, Medical University of Silesia, Katowice, Poland. Electronic address: kkusnierz@sum.edu.pl. · Institute of Materials Science, University of Silesia, Katowice, Poland. · Department of Gastrointestinal Surgery, Central Teaching Hospital, Katowice, Poland. · Department of Gastrointestinal Surgery, Medical University of Silesia, Katowice, Poland. ·J Surg Res · Pubmed #24189180.

ABSTRACT: BACKGROUND: The aim of this study was to evaluate the efficacy of a compression anastomosis clip (CAC) for gastrojejunostomy and comparison of a novel technique with a hand-sewn anastomosis. METHODS: Sixty-six patients underwent gastrojejunostomy with the CAC or hand-sewn anastomosis. The time of bowel function recovery, the duration of nasogastric drainage, the time of initiation of oral feeding, the duration of postoperative hospital stay, the time needed to expel the clip, and the observation of any complications were recorded. RESULTS: Neither group had anastomotic complications such as leakage or obstruction. Anastomosis time was shorter in the CAC group than in the control group (P < 0.01). The mean time of clip expulsion was 15.1 ± 6.04 d. There was no statistical difference in postoperative results between the two groups. There was a moderate positive correlation between the day of first bowel movement and the day of clip expulsion (r = 0.536) and a strong correlation between the duration of nasogastric drainage and the day of clip expulsion (r = 0.881). CONCLUSIONS: The method of using a CAC appeared to be safe, easy, inexpensive, and less time consuming. It should be taken into consideration that intra-abdominal complications may cause delayed CAC expulsion.

ABSTRACT: PURPOSE: Autoimmune pancreatitis (AIP) can mimic pancreatic cancer in its clinical presentation, imaging features and laboratory parameters. The aim of our study was to compare IgG, IgG4 and anti-CAIIAb serum levels in patients with AIP, pancreatic adenocarcinoma (PA) and chronic pancreatitis (CP) and to assess their clinical significance and utility in differential diagnosis of pancreatic diseases. PATIENT/METHODS: The study included 124 patients: 45 with PA, 24 with AIP and 55 with CP. Peripheral venous blood samples were obtained from all analyzed patients at the time of hospital admission and total IgG, IgG4 and anti-CAIIAB serum levels were measured using ELISA tests. RESULTS: Serum levels of IgG, IgG4 and anti-CAIIAb were significantly higher in patients with AIP compared to PA and CP patients (p<0.001). In AIP patients the median IgG levels were 19.7 g/l, IgG4 levels - 301.9 mg/dl and anti-CAIIAb - 81.82 ng/ml, compared to 10.61 g/l, 123.2mg/dl and 28.6 ng/ml, respectively, in PA patients. IgG4 for the cut-off 210 mg/dl showed the best sensitivity and specificity (83.8% and 89.5%) in AIP diagnosis compared to IgG (69.3% and 87.3%, respectively) and anti-CAIIAb (45.3% and 74.3%). However, 16 (35.5%) patients with PA and 14 (25.4%) patients with CP had IgG4 levels greater than 140 mg/dl. Moreover, in 3 (6.67%) patients with pancreatic cancer those values were greater than 280 mg/dl. No patients with CP had IgG4 more than 280 mg/dl. CONCLUSIONS: IgG4 at cut-off 210 mg/dl showed the best sensitivity and specificity in AIP diagnosis compared to IgG and anti-CAIIAb, however elevations of serum IgG4 may be seen in subjects without AIP, including pancreatic cancer.

Lekstan, Andrzej / Olakowski, Marek / Jabłońska, Beata / Łabuzek, Krzysztof / Olakowska, Edyta / Filip, Ines / Lampe, Paweł. · ·Pol Przegl Chir · Pubmed #23585206.

ABSTRACT: MATERIAL AND METHODS: The study group comprised 63 patients, including 25 (39.68%) female and 38 (60.32%) male patients. Group 1 (CP) consisted of 31 patients with CP (F: M = 10/21). Group 2 (PC) consisted of 32 patients with PC (F: M = 15:17). The pancreatic tumor samples were collected from the resected pancreas, being subject to electrophoresis and immunoenzymatic studies. After confirming their activity, MMP2, MMP9, TIMP1, TIMP2 concentrations were determined. Correlation analysis of MMPs and TIMPs concentrations was performed in relation to the following: tumor diameter, age, BMI, hospitalization, duration of symptoms and surgery, blood loss, incidence of perioperative complications. RESULTS: Group differences were presented in terms of: age, BMI, ASA, duration of symptoms, jaundice, tumor diameter, time of operation. There were no differences considering weight loss, blood loss, extent of resection, and hospitalization. Significant MMPs and TIMPs concentration differences between groups were demonstrated. CONCLUSIONS: Comparison of PC to CP tissue samples showed significantly higher levels of metalloproteinases and TIMPs in the former. Positive correlations of MMP1, TIMP1 and 2 with tumor diameter (CP) were observed, and MMP2 with the duration of surgery and blood loss (PC). There was no MMPs and TIMPs concentration levels influence on the incidence of postoperative complications.

Talar-Wojnarowska, Renata / Pazurek, Marek / Durko, Lukasz / Degowska, Malgorzata / Rydzewska, Grazyna / Smigielski, Jacek / Janiak, Adam / Olakowski, Marek / Lampe, Pawel / Grzelak, Piotr / Stefanczyk, Ludomir / Smolarz, Beata / Malecka-Panas, Ewa. ·Department of Digestive Tract Diseases, Medical University of Lodz, Lodz, Poland. r-wojnarowska@wp.pl ·Pancreatology · Pubmed #23127529.

ABSTRACT: BACKGROUND/AIMS: Analysis of cystic fluid may be useful in distinguishing between benign and malignant cysts which has significant impact on their management. The aim of our study was to assess the diagnostic utility of carcinoembryonic antigen (CEA) and K-ras gene mutation in pancreatic cysts fluid. METHODS: The study included 56 patients with pancreatic cystic fluid collected for analysis. The cysts were classified as benign (simple cysts, pseudocysts, serous cystadenoma) - 39 patients or premalignant/malignant (mucinous cystadenoma, IPMN, cystadenocarcinoma) - 17 patients. The patients history, CEA fluid concentrations and presence of K-ras mutation were analyzed. RESULTS: CEA were higher in patients with malignant cysts (mean levels 238 ± 12.5 ng/ml; range 32.8-4985 ng/ml) compared to benign lesions (mean levels 34.5 ± 3.7 ng/ml; range 3.9-693 ng/ml; p < 0.001). K-ras mutation correctly classified 11 of 17 patients with premalignant/malignant lesions. It was also detected in 1 patient with final diagnosis of benign cyst (the sensitivity 64.7% and the specificity 97.4%; p < 0.01). If CEA and molecular analysis were combined in that cysts with either CEA level>45 ng/ml or presence of K-ras mutation, than 16 of 17 premalignant/malignant cysts were correctly identified (94.1%). CONCLUSION: Molecular analysis of pancreatic cyst fluid adds diagnostic value to the preoperative diagnosis and should be considered when cyst cytologic examination is negative for malignancy.

10 Article Serous neoplasms of the pancreas constitute a continuous spectrum of morphological patterns rather than distinct clinico-pathological variants. A study of 40 cases. 2011

Pająk, Jacek / Liszka, Łukasz / Mrowiec, Sławomir / Zielińska-Pająk, Ewa / Gołka, Dariusz / Lampe, Paweł. ·Department of Histopathology, Medical University of Silesia, Katowice, Poland. ·Pol J Pathol · Pubmed #22246906.

ABSTRACT: Serous neoplasms (SN) of the pancreas account for 1-2% of all pancreatic tumours. Six morphological variants of SN were previously recognized: serous microcystic (cyst)adenoma, serous macrocystic (cyst)adenoma, von Hippel-Lindau-associated serous cystic neoplasm, solid serous adenoma/neoplasm, mixed serous-neuroendocrine neoplasm and serous cystadenocarcinoma. It was recently postulated that SN shows a continuous spectrum of morphological patterns rather than distinct clinico-pathological subtypes. To address this issue, we performed a detailed review of 40 SN cases diagnosed at our institution between 1989 and 2011. We found 11 cases of serous microcystic (cyst)adenoma, 5 cases of serous macrocystic (cyst)adenoma, and a single case of von Hippel-Lindau-associated serous cystic neoplasm. Apart from that, we found 20 cases of SN which showed features of both microcystic and macrocystic (cyst)adenomas, 2 cases of small 'incipient' SN and a single case of a mixed microcystic and solid adenoma. In conclusion, we showed that 'borderline' lesions among SNs truly exist and are not rare. The reason for such a wide diversity of morphological patterns of SN remains unknown.

11 Article Surgical treatment of pancreatic neuroendocrine tumours - clinical experience. 2011

Jabłońska, Beata / Dranka-Bojarowska, Daria / Palacz, Hanna / Lewiński, Adam / Lampe, Paweł. ·Department of Gastrointestinal Surgery, Silesian Medical University in Katowice. ·Pol Przegl Chir · Pubmed #22166361.

ABSTRACT: RESULTS: The mean hospitalisation period was 25 days (4-78 days). The mean procedure duration was 4.2 hours (1.15-9.15 hours). Early post-operative complications were observed in 10 patients (37.04%). The following early complications were observed: intra-abdominal abscess - 2, wound suppuration - 2, pancreatic fistula - 1, acute pancreatitis - 1, pancreaticojejunal anastomosis leak - 1, peritoneal cavity haemorrhage - 1, acute cholangitis - 1, adhesion obstruction - 1, subobstruction - 1, portal vein thrombosis - 1, sepsis - 1, fluid in pleural cavity - 1, acute heart failure - 1. There were performed 2 (7.41%) repeat surgeries: one due to adhesion obstruction and one due to peritoneal cavity haemorrhage. Death of 1 patient (3.71%) was recorded in the post-operative period due to acute heart failure. CONCLUSIONS: Pancreatic neuroendocrine tumours constituted the majority of gastroenteropancreatic neuroendocrine tumours in the analysed patient group. Most commonly, PNETs were localised in the head of the pancreas. In the presented material, the mortality rate does not exceed 4%, similarly as in other renowned centres.

12 Article Role of cyclooxygenase-2 gene polymorphisms in pancreatic carcinogenesis. 2011

Talar-Wojnarowska, Renata / Gasiorowska, Anita / Olakowski, Marek / Lampe, Pawel / Smolarz, Beata / Romanowicz-Makowska, Hanna / Malecka-Panas, Ewa. ·Department of Digestive Tract Diseases, Medical University, 22 Kopcinskiego, 90-153 Lodz, Poland. renata.talar-wojnarowska@umed.lodz.pl ·World J Gastroenterol · Pubmed #22039326.

ABSTRACT: AIM: To evaluate the clinical significance of -765G/C and -1195G/A cyclooxygenase-2 (COX-2) gene polymorphisms in patients with pancreatic cancer (PC). METHODS: The study included 201 patients: 85 with PC and 116 healthy controls. -765G/C and -1195G/A COX-2 gene polymorphisms were studied in DNA isolated from blood samples. The associations of the analyzed genotypes and clinical data at diagnosis were evaluated. RESULTS: We found an increased frequency of the homozygous -1195AA COX-2 genotype in patients with PC (53.7%) compared with the control group (21%) (P < 0.01). In contrast, the distribution of genotype and allele frequencies of the -765G/C COX-2 polymorphism in the PC patients were not different from those in control groups. A correlation between presence of homozygous -1195AA COX-2 genotype and tumor size > 3 cm was observed (P < 0.05). Analyzed polymorphisms were unrelated to the patients' sex and age, nor to the presence of regional or distant metastases. CONCLUSION: These preliminary results indicate that the -1195G/A COX-2 polymorphism may play an important role in PC prognosis and carcinogenesis.

13 Article Precursor lesions of early onset pancreatic cancer. 2011

Liszka, Lukasz / Pająk, Jacek / Mrowiec, Sławomir / Zielińska-Pająk, Ewa / Gołka, Dariusz / Lampe, Paweł. ·Department of Histopathology, Medical University of Silesia, Medyków 18, 40-754, Katowice, Poland. lliszka@mp.pl ·Virchows Arch · Pubmed #21369801.

ABSTRACT: Early onset pancreatic cancer (EOPC) constitutes less than 5% of all newly diagnosed cases of pancreatic cancer (PC). Although histopathological characteristics of EOPC have been described, no detailed reports on precursor lesions of EOPC are available. In the present study, we aimed to describe histopathological picture of extratumoral parenchyma in 23 cases of EOPCs (definition based on the threshold value of 45 years of age) with particular emphasis on two types of precursor lesions of PC: pancreatic intraepithelial neoplasia (PanIN) and intraductal papillary mucinous neoplasms (IPMNs). The types, grades, and densities of precursor lesions of PC were compared in patients with EOPCs, in young patients with neuroendocrine neoplasms (NENs), and in older (at the age of 46 or more) patients with PC. PanINs were found in 95.6% of cases of EOPCs. PanINs-3 were found in 39.1% of EOPC cases. Densities of all PanIN grades in EOPC cases were larger than in young patients with NENs. Density of PanINs-1A in EOPC cases was larger than in older patients with PC, but densities of PanINs of other grades were comparable. IPMN was found only in a single patient with EOPC but in 20% of older patients with PC. PanINs are the most prevalent precursor lesions of EOPC. IPMNs are rarely precursor lesions of EOPC. Relatively high density of low-grade PanINs-1 in extratumoral parenchyma of patients with EOPC may result from unknown multifocal genetic alterations in pancreatic tissue in patients with EOPCs.

14 Article Discrepancies between two alternative staging systems (European Neuroendocrine Tumor Society 2006 and American Joint Committee on Cancer/Union for International Cancer Control 2010) of neuroendocrine neoplasms of the pancreas. A study of 50 cases. 2011

Liszka, Łukasz / Pająk, Jacek / Mrowiec, Sławomir / Zielińska-Pająk, Ewa / Gołka, Dariusz / Lampe, Paweł. ·Department of Histopathology, Medical University of Silesia, Katowice, Poland. ·Pathol Res Pract · Pubmed #21354717.

ABSTRACT: The aim of our study was to identify and describe potential inconsistencies between two alternative staging systems of pancreatic neuroendocrine neoplasms (pNENs)--the European Neuroendocrine Tumor Society (ENETS) system (2006) and the American Joint Committee on Cancer/Union for International Cancer Control (AJCC-UICC) system (2010). To address this issue, we performed a retrospective clinico-pathological study of 50 cases of pNENs. We found 9 (18%) cases of ENETS/AJCC-UICC discrepancies regarding the primary tumor stage. They included 7 cases of T2/T3 disagreement and 2 cases of T3/T4 disagreement. In addition, we discussed the issue of potential T1/T2 discrepancy (however, we did not observe any such a case). Another inconsistency was related to the application of different stage prognostic groupings between both systems. In conclusion, the discrepancies between ENETS and AJCC-UICC staging systems for pNENs are relatively frequent and heterogeneous. We believe that they should be rigorously recognized. This is necessary for the evaluation of prognostic factors and the effectiveness of therapeutic options used in patients with pNENs.

15 Article Clinical value of serum neopterin, tissue polypeptide-specific antigen and CA19-9 levels in differential diagnosis between pancreatic cancer and chronic pancreatitis. 2010

Talar-Wojnarowska, Renata / Gasiorowska, Anita / Olakowski, Marek / Lekstan, Andrzej / Lampe, Paweł / Malecka-Panas, Ewa. ·Department of Digestive Tract Diseases, Medical University of Lodz, Katowice, Poland. r-wojnarowska@wp.pl ·Pancreatology · Pubmed #21242708.

ABSTRACT: BACKGROUND: Neopterin and tissue polypeptide-specific antigen (TPS) have been suggested to be useful in differential diagnosis between pancreatic adenocarcinoma (PA) and chronic pancreatitis (CP). The aim of our study was to compare the clinical usefulness of CA19-9, neopterin and TPS serum levels in patients with PA and CP. METHODS: The study included 85 patients with PA, 72 with CP and 50 healthy controls. The serum concentrations of neopterin, TPS and CA19-9 were measured (DRG International, USA). The associations of the analyzed markers and clinical data at diagnosis have been evaluated. RESULTS: Serum levels of neopterin, TPS and CA19-9 were higher in PA patients compared to CP (p < 0.001). TPS and CA19-9 levels were also elevated in patients with CP compared to the control group (p < 0.001). In contrast, there was no difference between neopterin serum levels in CP patients and the control group (p > 0.05). Neopterin showed the best sensitivity and specificity (91.8 and 87.5%) in PA diagnosis compared to CA19-9 (respectively 83.5 and 75%) and TPS (75.3 and 65.3%). CONCLUSION: Our results indicate that neopterin may be potentially useful in differential diagnosis between PA and CP. Assessment of TPS probably adds no significant information to that obtained with CA19-9 and neopterin. and IAP.

16 Article Age distribution patterns of patients with conventional ductal adenocarcinoma of the pancreas. A single-institution study of 580 cases re-evaluated using current histopathological diagnostic criteria. 2010

Liszka, Łukasz / Pająk, Jacek / Mrowiec, Sławomir / Zielińska-Pająk, Ewa / Lampe, Paweł / Gołka, Dariusz. ·Department of Histopathology, Medical University of Silesia, ul. Medyków 18, 40-754 Katowice. lliszka@mp.pl ·Pol J Pathol · Pubmed #20924989.

ABSTRACT: There are a few studies concerning epidemiology of pancreatic ductal adenocarcinoma (PDAC) in the Polish population. Analysis of age distribution patterns of patients with different types of cancer may be useful for studying their specific biology. In the present study we aimed to describe age distribution patterns of 580 patients with PDAC diagnosed in one centre during a 25-year period. All the histopathological diagnoses were re-reviewed using current histopathological diagnostic criteria. Age distributions of selected subpopulations of patients (defined based on gender, potential tumour resectability and type of the surgery) were compared using mean values, medians, age frequency density plots and logarithmic plots of age-specific frequencies. The mean and median values of patients' age were 60.8 y and 61.0 y, respectively. Females were approximately 2 y older than males at the time of PDAC diagnosis. Females with non-resectable PDAC were approximately 2 y older than females with resectable tumours. Mean age values of males with non-resectable and resectable PDAC were similar. Patients treated with pancreaticoduodenectomy were approximately 2 y older than patients undergoing other types of resections. Age distribution density plots showed that some subgroups of patients studied were somewhat heterogeneous and might include several yet poorly recognized clinico-pathological entities. Logarithmic plots of age-specific frequencies showed that PDAC epidemiology is in concordance with a multistage theory of carcinogenesis. PDAC is an age-dependent cancer. Single-institutional pathology-oriented cancer epidemiological databases may add some information to population-based cancer registries.

ABSTRACT: AIM: To develop a method of gross examination of pancreaticoduodenectomy specimens with pancreatic ductal adenocarcinoma, allowing adequate assessment of the entire pancreatic surface as a surgical margin, which would not affect the lymph node yield. METHODS: We retrospectively compared the R1 rates (i.e., proportions of patients with microscopic residual tumour at surgical margins) and lymph node yield in a series of 67 consecutive cases of pT3 ductal adenocarcinomas diagnosed in pancreaticoduodenectomy specimens during three different periods of time and sampled using three different approaches: (1) period 2006-2007, when the pancreatic surface (except for the transection margin and superior mesenteric artery margin) was not examined; (2) period January-September 2008, when the posterior pancreatic surface (posterior circumferential radial margin) was examined using an improved method based on sampling of 2.0-2.5 mm thick consecutive slices perpendicular to the duodenal axis; and (3) period October 2008 - June 2009, when the whole surface of the pancreatic head was sampled using the approach mentioned above. RESULTS: The R1 rates in three consecutive time periods were 23.5%, 40% and 53.8%, respectively. Median numbers of retrieved peripancreatic lymph nodes were 11.0, 12.0 and 14.0, respectively. CONCLUSIONS: The newly proposed approach allowed adequate assessment of the entire pancreatic head surface as a surgical margin and reduced the risk of under-detection of R1 status. Moreover, this approach did not affect the number of peripancreatic lymph nodes examined.

ABSTRACT: The aim of the study was to analyze the gene expression profile of pancreatic cancer to derive novel molecular markers of this malignancy. The snap-frozen or RNA-later preserved samples of 18 pancreatic adenocarcinomas, 5 chronic pancreatitis cases and 6 specimens of grossly normal pancreas were used for microarray analysis by HG-U133 Plus 2.0 oligonucleotide Affymetrix arrays. Validation was carried out by real-time quantitative PCR (Q-PCR) in the set of 66 samples: 31 of pancreatic cancer, 14 of chronic pancreatitis and 21 of macroscopically unchanged pancreas. By Principal Component Analysis of the microarray data we found a very consistent expression pattern of normal samples and a less homogenous one in chronic pancreatitis. By supervised comparison (corrected p-value 0.001) we observed 11094 probesets differentiating between cancer and normal samples, while only seventy six probesets were significant for difference between cancer and chronic pancreatitis. The only gene occurring within the best 10 genes in both comparisons was S100 calcium binding protein P (S100P), already indicated for its utility as pancreatic cancer marker by earlier microarray-based studies. For validation we selected two genes which appeared as valuable candidates for molecular markers of pancreatic cancer: neuroblastoma, suppression of tumorigenicity 1 (NBL1) and anillin (ANLN). By Q-PCR, we confirmed statistically significant differences in these genes with a 9.5 fold-change difference between NBL1 expression in cancer/normal comparison and a relatively modest difference between cancer and pancreatitis. For ANLN even more distinct differences were observed (cancer/normal 19.8-fold, cancer/pancreatitis 4.0-fold). NBL1 and anillin are promising markers for pancreatic carcinoma molecular diagnostics.
