ABSTRACT: AIM: To analyze pancreatic cancer patients who developed metachronous pulmonary metastases (MPM) as a first site of recurrence after the curative-intent surgery. METHODS: One-hundred-fifty-nine consecutive pancreatic ductal adenocarcinoma (PDAC) patients who underwent radical pancreatic surgery between 2006 and 2013 were included in this retrospective analysis. The clinical data including age, sex, grade, primary tumor location, pTNM stage, lymph node infiltration, microangioinvasion, perineural invasion, lymphovascular invasion, the therapy administered, and follow-up were all obtained from medical records. Further analysis covered only patients with metachronous metastases. Clinical and histopathological data (age, sex, grade, primary tumor location, pTNM stage, lymph node infiltration, microangioinvasion, perineural invasion, lymphovascular invasion, the therapy administered and follow-up) of patients with metachronous non-pulmonary metastases and patients with metachronous pulmonary metastases were statistically assessed. Disease-free survival (DFS) from pancreas resection until metastases onset and overall survival (OS) were calculated. Wilcoxon test, χ RESULTS: Metachronous pulmonary metastases were observed in 20 (16.9%) and were operable in 3 (2.5%) of PDAC patients after a prior curative-intent surgery. Patients with isolated pulmonary metastases (oligometastases and multiple metastases) had estimated prior DFS and OS of 35.4 and 81.4 mo, respectively, and those with metachronous pulmonary metastases accompanied by other metastases had prior DFS and OS of 17.3 and 23.4 mo, respectively. Patients with non-pulmonary metastases had prior DFS and OS of 9.4 and 15.8 mo, respectively. Different clinical scenarios according to the presentation of MPM were observed and patients could be divided to three subgroups with different prognosis which could be used for the selection of treatment strategy: isolated pulmonary oligometastases, isolated multiple pulmonary metastases and pulmonary metastases accompanied by other metastases. CONCLUSION: Surgery should be considered for all patients with isolated pulmonary oligometastases, but the risk of intervention has to be individually weighted for each patient.

ABSTRACT: BACKGROUND: This dual-center, randomized controlled trial aimed to compare 2 types of intra-abdominal drains after pancreatic resection and their effect on the development of pancreatic fistulae and postoperative complications. METHODS: Patients undergoing pancreatic resection were randomized to receive either a closed-suction drain or a closed, passive gravity drain. The primary endpoint was the rate of postoperative pancreatic fistula. A secondary endpoint was postoperative morbidity during follow-up of 3 months. The planned sample size was 223 patients. RESULTS: A total of 294 patients were assessed for eligibility, 223 of whom were randomly allocated. One patient was lost during follow-up, and 111 patients in each group were analyzed. The rate of postoperative pancreatic fistula (closed-suction 43.2%, passive 36.9%, P = .47) and overall morbidity (closed-suction 51.4%, passive 40.5%, P = .43) were not different between the groups. We did not find any differences between the groups in reoperation rate (P = .45), readmission rate (P = .27), hospital stay (P = .68), or postoperative hemorrhage (P = .11). We found a significantly lesser amount of drain fluid in the passive gravity drains between the second and fifth postoperative days and also on the day of drain removal compared with closed-suction drains. CONCLUSION: The type of drain (passive versus closed suction) had no influence on the rate of postoperative pancreatic fistulae. The closed-suction drains did not increase the rate of postoperative complications. We found that the passive gravity drains are more at risk for obstruction, whereas the closed-suction drains kept their patency for greater duration.

ABSTRACT: INTRODUCTION: Pancreatic cancer (PDAC) is one of the most aggressive malignancies. Its incidence increases worldwide and, despite the developments in cancer research, mortality rates have not decreased. Poor prognosis of the disease is due to many factors, mainly late diagnosis. Distant metastases and peritoneal carcinomatosis are caused by hematogenous and lymphogenous spreading of the tumorous cells. One of the factors that may influence patient survival are so-called circulating tumor cells (CTCs). The aim of our work was to evaluate the possible influence of CTCs on the survival of patients with PDAC. METHOD: We included patients who underwent a radical or palliative surgical intervention at the First Department of Surgery of Medical Faculty and University Hospital in Olomouc between 1 January 2008 and 31 December 2012. The required samples for CTCs detection were taken from each patient. The detection of the CTCs was performed using real-time RT-PCR. The results were statistically processed and evaluated. RESULTS: We included 126 patients in total, of which 88 were treated radically and 38 received palliative treatment. Mean age was 63 years in patients with radical and 64 years in patients with palliative surgery. Mean survival time in radically treated patients was 29.6 months, in patients with palliative treatment the mean survival time was 8.5 months. The survival time of radically treated patients with CTCs was 27.2 months, without CTCs it was 33.8 months. CONCLUSION: We did not prove a statistically significant difference in survival between radically treated PDAC patients with and without detected CTCs in our work.Key words: pancreatic cancer - circulating tumor cells survival.

ABSTRACT: INTRODUCTION: Solid pseudopapillary neoplasm (SPN) is a very rare neoplasm that occurs in girls and young women in 90% of cases; the range is 779 years of age, and the median is 28 years of age. This tumour was first described by Virginia Frantz in 1959 as a papillary cystic tumour of the pancreas. METHODS: The aim of this retrospective study was to analyse the incidence of SPN in all patients with a pancreatic tumour operated at the 1st Dept. of Surgery, University Hospital Olomouc between years 2006 and 2015. Clinical symptoms, imaging methods used, tumour marker positivity, histological findings, postoperative complications and disease-free interval were all evaluated. RESULTS: Of the 454 patients operated on between 20062015, the diagnosis of SPN was made in five female patients. The following imaging methods were used in the preoperative diagnostic process: CT, MRI, PET/CT and endosonography. In four patients the tumour was localised in the tail of the pancreas; these women underwent left-sided pancreatectomy. In one patient, the tumour was located in the pancreatic head and a pylorus-preserving pancreaticoduodenectomy was performed. Complications were seen only in one patient who underwent revision on the first postoperative day for bleeding from the pancreatic cut surface. Pancreatic fistula was not observed in any of the patients. The procedures were considered as sufficient from the oncological viewpoint due to the radical resection procedure and negative resection margin, and therefore no adjuvant oncological treatment was indicated in any of the patients. During the follow-up period, recurrence was not observed in any one of the patients. CONCLUSION: Solid pseudopapillary neoplasm of the pancreas is a rare disorder with a low malignant potential occurring primarily in young women. Generally, SPN has a good prognosis; however, advanced stages of the disease with distant metastases may be encountered in rare cases. The only curative treatment is radical surgical resection.Key words: solid pseudopapillary neoplasm Frantzs tumour pancreas.

ABSTRACT: INTRODUCTION: The investigation of prognostic and predictive factors for early diagnosis of tumors, their surveillance and monitoring of the impact of therapeutic modalities using hybrid laboratory models in vitro/in vivo is an experimental approach with a significant potential. It is preconditioned by the preparation of in vivo tumor models, which may face a number of potential technical difficulties. The assessment of technical success of grafting and xenotransplantation based on the type of the tumor or cell line is important for the preparation of these models and their further use for proteomic and genomic analyses. METHODS: Surgically harvested gastrointestinal tract tumor tissue was processed or stable cancer cell lines were cultivated; the viability was assessed, and subsequently the cells were inoculated subcutaneously to SCID mice with an individual duration of tumor growth, followed by its extraction. RESULTS: We analysed 140 specimens of tumor tissue including 17 specimens of esophageal cancer (viability 13/successful inoculations 0), 13 tumors of the cardia (11/0), 39 gastric tumors (24/4), 47 pancreatic tumors (34/1) and 24 specimens of colorectal cancer (22/9). 3 specimens were excluded due to histological absence of the tumor (complete remission after neoadjuvant therapy in 2 cases of esophageal carcinoma, 1 case of chronic pancreatitis). We observed successful inoculation in 17 of 28 tumor cell lines. CONCLUSION: The probability of successful grafting to the mice model in tumors of the esophagus, stomach and pancreas is significantly lower in comparison with colorectal carcinoma and cell lines generated tumors. The success rate is enhanced upon preservation of viability of the harvested tumor tissue, which depends on the sequence of clinical and laboratory algorithms with a high level of cooperation.Key words: proteomic analysis - xenotransplantation - prognostic and predictive factors - gastrointestinal tract tumors.

ABSTRACT: INTRODUCTION: Pancreatic cancer (PDAC) is one of the most aggressive malignancies. Its poor prognosis is due to a combination of various factors, mainly aggressive biology of the tumour, non-specific symptoms in early stages, their underestimation, prolonged time to diagnosis and late onset of treatment. The majority of patients are diagnosed in an advanced stage of the disease. Median survival of these patients ranges from 211 months. The most common consequences of locally advanced disease that require intervention include obstruction of the duodenum and biliary obstruction. The purpose of our study was to analyze the survival of patients with radically inoperable PDAC undergoing palliative surgery or exploration with biopsy, and to evaluate the influence of patient and tumour factors and treatment modalities on survival. METHODS: In our retrospective study we included all patients with radically inoperable PDAC undergoing a non-radical surgical intervention between 01 January 2006 and 31 December 2014. Patient age, histopathological findings, surgical and oncological treatment and survival were included in the analysis. The results were statistically processed and evaluated using IBM SPSS Statistics software version 22 (USA). RESULTS: 184 patients with radically inoperable PDAC, 105 males and 79 females, were included in our study. Mean age of the patients was 64 years and most patients presented with stage IV of the disease. Mean survival time was 7.04 months and median 4.7 months. CONCLUSION: We determined a statistically significant influence of the following factors on patient survival: sex, stage, presence of distant metastases at the time of surgery and oncological treatment administration. Mean and median survival of patients with radically inoperable tumours matches global statistics. KEY WORDS: pancreatic cancer - radically non-resectable - palliative surgery - survival.

ABSTRACT: INTRODUCTION: The aim is to map the current situation in the surgical treatment of pancreatic cancer in the Czech Republic. This information has been obtained from surgical treatment providers using a simple questionnaire and by identifying the so called high volume centres. The information has been collected in the interest of organizing and planning research projects in the field of pancreatic cancer treatment. METHOD: We addressed centres known to provide surgical treatment of pancreatic cancer. A simple questionnaire formulated one question about the total number of pancreatic resections, also separately for the diagnoses PDAC - C25, in the last two years (2014 and 2015). Other questions focused on the use of diagnostic methods, neoadjuvant therapy, preoperative assessment of risks, the possibility of rapid intraoperative histopathology examination, Leeds protocol, monitoring of morbidity and mortality including long-term results, and the method of postoperative follow-up and treatment. ÚZIS (Institute of Health Information and Statistics of the Czech Republic) was addressed with a request to analyze the frequency of reported total numbers for DPE, LPE, TPE and to do the same with respect to diagnosis C 25 for the last two years, available for the entire Czech Republic (2013, 2014). RESULTS: Altogether 19 institutions were identified by the preceding audit, which reported more than 10 pancreatic resections annually; these institutions were addressed with the questionnaire. Sixteen institutions responded to the questions, 13 of them completely. CONCLUSION: The majority of potentially radical surgeries for PDAC in the Czech Republic are carried out at 6 institutions. All of the institutions that participated in the survey collect data about morbidity and mortality and monitor their results. KEY WORDS: pancreas cancer outcomes surgery.

ABSTRACT: AIM: To analyse the 5-year survival rate of patients undergoing radical surgery for pancreatic ductal adenocarcinoma (PDAC) and to identify prognostic factors. METHODS: A prospectively maintained database of 90 consecutive patients who underwent radical resection for PDAC was analysed. Survival was evaluated using the Kaplan-Meier method. Log-rank test and Cox regression analysis were used for the evaluation of prognostic factors. P values less than 0.05 were considered significant. RESULTS: Mean age (± standard deviation) was 63.2±8.6 years (female 28.9% and male 71.1%). Tumour localisation was in the head in 76 (84.5%), multifocal in 3 (3.3%) and in the body/tail in 11 (12.2%). Pancreatic head resection was performed in 75 (83.3%), total pancreatectomy in 4 (4.4%) and distal pancreatectomy with splenectomy in 11 (12.2%), with standard lymphadenectomy. Venous resection was in 4 (4.4%). Thirty-day and in-hospital mortality occurred in 1 (1.1%), 90-day mortality was 3.3%. On univariate analysis absence of perineural and vascular invasion, stage, absence of lymph node infiltration and no need for transfusion were associated with improved overall survival. On multivariate analysis vascular invasion HR=3.137 (95%CI: 1.692-5.816; P = 0.0003) and postoperative complications HR=2.004 (95%CI: 1.198-3.354; P = 0.008) were identified as significant independent predictors of survival. The five-year survival rate was 18.9%, with five-year recurrence-free survival of 16.7%. CONCLUSION: Vascular invasion and postoperative complications were independent prognostic factors after curative resections of pancreatic cancer in studied cohort.

ABSTRACT: INTRODUCTION: The purpose was to identify 5-year survivors among a group of radically resected patients with pancreatic cancer and analyse the characteristics and factors associated with their 5-year survival. Single tertiary centre experience. METHOD: A prospectively maintained database of 155 pancreatic resections from January 2006 to June 2010 was scanned to identify patients after curative radical resections for pancreatic ductal adenocarcinoma. The clinical and pathological data was analysed retrospectively. The outcomes of the PDAC group were evaluated using Kaplan-Meier analysis (survival) with the Log-rank test and Cox regression analysis (evaluation of prognostic factors). Characteristics of the survivors were discussed. Significance level of 0.05 was used. Those factors were used as independent variables for Cox regression analysis whose significant effect on survival was shown based on Kaplan-Meier analysis. RESULTS: Among 155 patients undergoing a curative pancreatic resection, 73 had a pancreatic ductal adenocarcinoma. Fifteen patients (20.5%) after radical surgery survived over 5 years, 13 of whom are still alive. In the group of the survivors, the mean overall survival was 77.1 months (60110) and the median survival was 74 months. The mean relapse-free interval in the group of the survivors was 63.3 months (14110) with the median of 65 months. Factors associated with a longer survival included the absence of lymph node infiltration (p=0.031), uncomplicated postoperative course (p=0.025), absence of vascular invasion (p=0.017), no blood transfusions (p=0.015) and the use of postoperative therapy - predominantly chemotherapy (p=0.009). Significant independent predictors of survival included vascular invasion HR=2.239 (95%CI: 1.0934.590; p=0.028), postoperative chemotherapy HR=2.587 (95%CI: 1.3015.145; p=0.007) and blood transfusion HR=2.080 (95%CI: 1.0274.212; p=0.042). The risk of death was increased 2.2 times in patients with vascular invasion, 2.1 times in patients with transfusions, and finally 2.6 times in those with no chemotherapy. CONCLUSION: Factors associated with an improved overall survival included: the absence of lymph node infiltration, an uncomplicated postoperative course, absence of vascular invasion, no need of blood transfusions, and finally the use of postoperative chemotherapy. Vascular invasion, use of blood transfusions and postoperative adjuvant chemotherapy were significant independent prognostic factors of survival.

Ghothim, M / Srovnal, J / Bébarová, L / Tesaříková, J / Skalický, P / Klos, D / Prokopová, A / Vahalíková, M / Slavík, H / Vrbková, J / Neoral, Č / Havlík, R / Hajdúch, M / Loveček, M. · ·Rozhl Chir · Pubmed #26766154.

ABSTRACT: INTRODUCTION: The aim of this study is to assess the significance of CEA, EGFR and hTERT as markers of occult tumor cells for predicting treatment outcomes in pancreatic cancers, as well as determining the cut-off values of these markers individually in peritoneal lavage. METHOD: The study compared 87 patients undergoing palliative operations (bypass surgery, biological sampling for subsequent oncological treatment) for either stage III or IV (UICC) pancreatic ductal adenocarcinomas with a control group of 24 healthy patients. Abdominal cavity lavage was performed at the beginning of the surgery in both groups, using 100 ml of physiological solution (phosphate buffered saline, pH 7.2). The samples were transported in bottles containing 1.5 ml 0.5 M EDTA and 10 ml of fetal bovine serum. Total RNA samples were all processed and purified by reverse transcription. Occult tumor cells in the peritoneal lavage were detected by the real-time RT-PCR method using CEA, EGFR and hTERT as markers of tumor cells. Another aim was to calculate the cut-off values of these markers. Statistical analysis was done using software R (www.r-project.org) and Statistica (StatSoft, Inc. USA). RESULTS: Mean expression of CEA, EGFR and hTERT in peritoneal lavage in the control group was 2501, 716749 and 104 copies of mRNA / mg RNA. Threshold, cut-off values were determined as the "mean + 2 times standard deviation". Absolute expression values were further normalized to expression of the house-keeping gene glyceraldehyde-3-phosphate dehydrogenase (GAPDH). After normalization, cut-off values of the tested markers were 4.89, 115.88 and 0.02 copies of mRNA/GAPDH mRNA. As regards absolute expression of the markers tested, only hTERT was able to statistically significantly (p<0.001) distinguish the analysed groups, where patients with advanced pancreatic adenocarcinoma had a higher expression of hTERT. Absolute expression of CEA or EGFR was not able to discriminate between the two groups. The more accurate normalized expression values of the test markers demonstrated a statistically significantly higher expression of hTERT (p<0.005) and CEA (p<0.001) in patients with advanced adenocarcinoma compared to the control group. CONCLUSION: Absolute hTERT expression in peritoneal lavage of patients with advanced pancreatic cancer was significantly higher compared to the control group.

ABSTRACT: INTRODUCTION: The occurence of synchronous pancreatic cancer and other primary cancer is not frequent and reaches about 5.6% as reported in autoptic studies. Double resections of the pancreas with another organ due to synchronous malignancies have been published only in quite sporadic sets of cases or individual case reports. The authors present three cases of synchronous pancreatic malignancies and stomach or renal cancers treated with surgery, including results and survival. CASES: Three patients with synchronous double cancer were identified in a series of 400 pancreatic resections (20062014). Two patients presented with symptoms of pancreatic periampullary tumors (bile duct obstruction, weight loss and abdominal pain). The second malignancies were identified as incidental during diagnostic work-up (asymptomatic cancer of the stomach, kidney). Pancreatoduodenectomies (PDE) with lymphadenectomies were performed due to ductal adenocarcinomas (pT2N1M0 G3 and pT3N1M0 G2). The second procedures included subtotal gastrectomy with lymphadenectomy (gastric adenocarcinoma pT1N1M0, G2) and nephrectomy (renal papillary carcinoma pT1bN0M0, G3). Postoperative adjuvant chemotherapy with gemcitabine was given in both patients. Survival rates were 12 and 19 months, respectively. The third patient suffered from abdominal pain and weight loss. Diagnostic work-up revealed stomach carcinoma and early pancreatic adenocarcinoma. Double resection - subtotal gastrectomy with lymphadenectomy and pancreatoduodenectomy with lymphadenectomy - was performed. Gastric adenocarcinoma pT2N2M0, G3 and pancreatic ductal papillary-mucinous adenocarcinoma pT2N0M0, G1 were found in the specimens. Adjuvant radiochemotherapy with 5-fluorouracil and leukovorine was given postoperatively. This patient is still alive nearly 5 years after the surgery, without any reccurence. CONCLUSION: The survival of patients with double synchronous pancreatic malignancies and other primary tumors in our set seems to be influenced by the stage and biology of pancreatic cancer. The survival was worse when the duplicity was presented with symptoms of pancreatic cancer. Pancreatic cancer found incidentally when another malignancy is presented has more favourable results.

ABSTRACT: INTRODUCTION: Although generally uncommon, pancreatic metastases are increasingly encountered in clinical practice. The benefit of pancreatic resections in this setting is unclear and still being discussed. Renal cell carcinoma is the most frequent primary tumour metastasing to the pancreas--R0 resections in cases of solitary metastases can be performed. Resections in malignant melanoma and ovarian cancer are rather considered as palliative. The aim of this study is to analyse our own set of patients operated on for metastases into the pancreas and evaluate the results of their surgical treatment. METHODS: We identified the patients operated on for metastases to the pancreas. Patient and tumour characteristics were summarized using descriptive statistics. RESULTS: A total of 9 patients (out of 312 patients undergoing resection for malignancy in the period of 2006-2014) with pancreatic metastases were analysed. All but one were asymptomatic; the symptomatic patient suffered from GI bleeding. All patients had a metachronous lesion with a median length of 12 years (421 years) between the initial operation and pancreatic resection. The most common metastasing tumour was renal cell carcinoma (77%) with the highest incidence occurring at the head of the pancreas (44%). The most frequent procedure used was the pylorus-preserving pancreatic head resection (44%). The median operating time was 247 min, (126375 min). Six patients were complication free, the median of their hospital stay was 9.5 days (812 days). Complications included PPH type C and PF type B both of which required surgical intervention; however, PF type A required no intervention. No postoperative deaths occurred, multiple metastases were found in 4 patients with renal cell carcinoma metastases. The median of follow-up has been 11.5 months, (334 months). CONCLUSION: Survival after pancreatic resections due to renal cell carcinoma is favourable. Mortality is low and morbidity is similar to that associated with pancreatic resections due to other aetiologies, making surgery a valid and safe treatment option. Lifelong follow-up of patients after nephrectomy is advised. Resections in pancreatic metastases of malignant melanoma or ovarian carcinoma are considered as palliative, their indication being individual following interdisciplinary consultation.

13 Article [The importance of endosonography in preoperative management of patients with pancreatic head carcinoma]. 2012

ABSTRACT: INTRODUCTION: Pancreatic ductal cancer remains a devastating disease with an urgent need for improved diagnostics and new treatment strategies. It has no early specific symptoms, shows rapid progression and is practically undiagnosable in the early stage. Survival of radically operated patients is rather unsatisfactory. Nonetheless, only radical surgical resection offers potentially curative treatment. MATERIAL AND METHODS: The authors present a set of 70 patients (2009-2011) who underwent radical surgery - pancreatic head resection - for ductal pancreatic head adenocarcinoma. A retrospective study analyzes the accuracy of T-staging using preoperative CT and EUS. RESULTS: In 21 (30%) patients, CT did not prove pathology in the head of the pancreas. Subsequent endosonography revealed a mass in the head of the pancreas in 88% of patients with negative CT scans. The conformity of CT (detection of the mass) with the histopathological finding was detected in 68.2% of cases, 95% CI for compliance: 55.6%-79.1%. The conformity of endosonography (detection of the mass) with the histopathological finding was detected in 96.0% of cases, 95% CI for compliance: 86.3%-99.5%. The conformity between CT and endosonography was found in 68.8% of cases, 95% CI for compliance: 53.8%-81.3%. The conformity of preoperative CT staging and final histopathological staging was observed in 18.2% of cases, 95% CI for compliance: 9.8%-29.6%. The conformity of preoperative endosonography staging and final histopathological staging was seen in 42.0% of cases, 95% CI for compliance: 28.2%-56.8%. The conformity of accuracy of preoperative CT staging and endosonography staging was detected in 37.5% of cases, 95% CI for compliance: 23.9%-52.7%. In 58.3% of cases, endosonography compared with CT findings evaluated higher T stage (p = 0.001). CONCLUSION: Pancreatic head carcinoma presents mostly with obstructive jaundice. CT diagnosis of small tumours often fails. Subsequent endosonography in case of a negative CT usually contributes significantly to the final diagnosis and helps determine the indication for surgery. EUS is more accurate than CT in showing the tumour mass in the pancreatic head. In our group EUS revealed the mass in 96% of patients versus 68% in CT. When evaluating the staging, CT is accurate only in 18.2% of patients, EUS in 42% of patients. Both methods, EUS and particularly CT, underestimate the actual final T-staging of the disease.

ABSTRACT: INTRODUCTION: Surgical treatment plays a key role in the efforts to improve prognosis of patients with pancreatic cancer. The pancreatic cancer incidence rates are on increase and so does the number of patients undergoing potentially curative resection procedures. However, despite all diagnostic advancements and treatments adjusted to specific patient's needs, the outcomes are not satisfactory enough. The aim of the surgical procedure is to radically remove the tumor, including the regional lymph nodes, to promote early and uncomplicated healing and to facilitate early initiation of oncological treatment. AIM: The aim of the study was to assess current potential of diagnostic and surgical treatment in pancreatic cancer when all currently available diagnostic methods are emloyed and to present the university clinic's outcomes. METHODS AND PATIENT GROUP: From 2006 to IX 2010, a total of 177 pancreatic resections and 123 right-sided pancreatoduodenectomies for malignant disorders were performed at the authors' clinic. 76 pancreatoduodenectomies were performed for ductal carcinoma of the pancreatic head. The study group included 51 males and 25 females, the mean age of 62.9 years. Based on the TNM classification (UICC), 11% of the subjects presented with stage I, 78% with stage II and 3% with stage III diseases. The procedures radicality was the following: R0 in 59 subjects, R1 in 5 subjects while in 12 subjects, the radicality was undetected by the authors. Histopatological grading in this patient group was as follows: G1 in 20%, G2 in 34% and G3 in 46% of the subjects. Perineural invasion, invasion into lymphatic vessels or other vessels was not detected in 21 subjects (27.6%). The authors assessed complication rates based on the DeOliveira classification and survival rates in individual disease stages. OUTCOMES: Complications occurred in 44.7% of the operated subjects. Serious complications requiring reintervention were reported in 13 subjects (17.1%), including reinterventions in general anesthesia in 10 subjects (13.1%). Two patients died: a 79-year old female died from multiorgan failure as a result of aspiration, and a 76-year old male died from multiorgan failure following completion of pancreatectomy due to pancreaticojejunal anastomosis insufficiency. The thirty- and sixty-day mortality rate was 2.6%, however, it was null over the past three years. The mean survival time was 17.1 months, with the median of 13.5 months. The patient group's overall 3-, 6-, 9-, 12, 15- and 18- month survival following radical resections was 95.6%, 90.3%, 76.3%, 62.7%, 52.3% and 45%, respectively. 82%, 52%, 35% and 35% of the operated stage I patients survived 1, 2, 3 and 4 years, respectively. The mean hospitalization duration was 16.8 days (10-45). CONCLUSION: Although the procedures are extremely demanding, especially in the reconstruction phase, the outcomes have improved significantly due to ongoing experience, improvements in the surgical technique and in the complex postoperative care. At specialized clinics, the mortality rate has dropped below 5%, the morbidity rate below 40% and the postoperative dehiscence rates below 10%. During the past three years, the authors' clinic has reached null 30- and 60-day mortality rate following the pancreatic head resections, the complication rate following pancreaticoduodenal anastomosis is slightly above 5% (6.5%) and the morbidity rate is slightly above 40% (44.7%). The authors consider the procedure safe at their clinic and all indicated patients are expected to benefit from it.

ABSTRACT: INTRODUCTION: Pancreatic cancer is one of the most aggressive malignity with the statistically shown an upward trend and a very poor prognosis. The causes we follow up in the local recurrence and in the early dissemination, either through hematogenic or lymphogenic way. Conventional methods are not able to capture these cells, just the modern molecular-biological methods make possible to fix the so-called minimal residual disease, that is the presence of isolated tumor cells in the patient's body. MATERIAL AND METHODS: The study included 52 patients operated on the Clinic of Surgery I. in the University Hospital Olomouc for pancreatic cancer in different stages. QRT-PCR method was determined expression of hTERT, EGFR 1 and CEA both in peripheral blood, portal blood, bone marrow, peritoneal lavage and the tumor itself. RESULTS AND CONCLUSION: The results of this pilot study demonstrated a high sensitivity and specificity of the PCR method for detection of circulating tumor cells in patients with pancreatic cancer, extending this methodology, we are able to provide prognostic value of minimal residual disease and its significance for the indication of radical surgery for pancreatic cancer.
