Abstract
BACKGROUND The American Joint Committee on Cancer (AJCC) staging system has limited accuracy in predicting survival of gastric cancer patients with inadequate counts of evaluated lymph nodes (LNs). We therefore aimed to develop a prognostic nomogram suitable for clinical applications in such cases. METHODS A total of 1511 noncardia gastric cancer patients treated between 1990 and 2010 in the academic surgical center were reviewed to compare the 7th and 8th editions of the AJCC staging system. A nomogram was developed for the prediction of 5-year survival in patients with less than 16 LNs evaluated (n = 546). External validation was performed using datasets derived from the Polish Gastric Cancer Study Group (n = 668) and the SEER database (n = 11,225). RESULTS The 8th edition of AJCC staging showed better overall discriminatory power compared to the previous version, but no improvement was found for patients with < 16 evaluated LNs. The developed nomogram had better concordance index (0.695) than the former (0.682) or latest (0.680) staging editions, including patients subject to neoadjuvant treatment, and calibration curves showed excellent agreement between the nomogram-predicted and actual survival. High discriminatory power was also demonstrated for both validation cohorts. Subsequently, the nomogram showed the best accuracy for the prediction of 5-year survival through the time-dependent ROC curve analysis in the training and validation cohorts. CONCLUSIONS A clinically relevant nomogram was built for the prediction of 5-year survival in patients with inadequate numbers of LNs evaluated in surgical specimens. The predictive accuracy of the nomogram was validated in two Western populations.

Abstract
BACKGROUND The aim of this study was the analysis of the influence of prognostic factors on short- and long-term outcomes of gastric cancer resection. PATIENTS AND METHODS A database of 709 patients who had gastric cancer resection between 2007 and 2015 was compiled. RESULTS Total gastrectomy (TG) and subtotal proximal gastrectomy (SPG) significantly increased the risk of overall complications (p=0.0015 and 0.0173, respectively) and surgical complications (p=0.0141 and 0.0035, respectively). Moreover the resection of an additional organ was an independent prognostic factor of overall complications (p<0.0001), systemic complications (p=0.0503), surgical complications (p<0.0001) and relaparotomy (p=0.0259). T stage (p<0.0001), N stage (p<0.0001), M stage (p<0.0001) and radical resection (p<0.0001) significantly affected 5-year survival rates. CONCLUSION Early diagnosis and radical resection was crucial in 5-year survival rates. However, the type of gastrectomy and the resection of an additional organ were the most important factors in short-term outcomes of treatment for such patients.

Abstract
Background: Little data are available for abscess and non-abscess abdominal fluid collections (AFCs) after gastric cancer surgery and their clinical implications. We sought to analyse the natural history of such collections in a population of patients subject to routine postoperative imaging.Methods: From 1996 to 2012, 1381 patients underwent gastric resections and routine postoperative monitoring with abdominal ultrasound. As a unit protocol, examinations were carried out in all patients prior to drain removal, immediately before discharge, and at follow-up visits.Results: AFCs were diagnosed in 134 (9.7%) patients after a median time from surgery of seven days (interquartile range (IQR) 5-11 days). Sixty-four of the 134 AFCs (48%) were asymptomatic and resolved spontaneously after a median follow-up of 26.5 days (IQR 14-91 days). Seventy (52%) AFCs required interventional drainage. A stepwise logistic regression model demonstrated that interventional treatment was much more likely among patients with enteric fistula (odds ratio (OR) 9.542, 95% CI 1.418-46.224, p=.003) and pancreatic fistula (OR 7.157, 95% CI 1.340-39.992, p=.012).Conclusions: About one half of AFCs after gastric surgery were asymptomatic and eventually resolved spontaneously without any intervention. However, the need for interventional drainage was significantly increased by coexisting pancreatic or enteric fistula.

Abstract
Objectives: Gastric cancer (GC) in young patients is a troubling clinical problem. The aim of this study was to analyze whether patients ≤40 years of age with GC differ from patients (age >40 years) in terms of clinicopathological and selected genetic factors.Materials and methods: Between 1984 and 2011, data were collected for 840 GC patients diagnosed and treated for GC at the Department of Gastroenterology at Pomeranian Medical University. The following clinicopathological features were compared between two age groups: sex, symptom duration, family history of cancer, tumor site, stage (early vs. advanced), blood group, histology, Helicobacter pylori infection and BRCA2 C572T silent mutation status.Results: A total of 65 (7.7%) patients were age 40 years or younger. GC was predominant in women in the younger group (p < .001). Patients (≤40 years) more frequently reported a positive family history of cancer (p = .01) and a diffuse tumor type was more common in this group (p < .001). The two age groups did not differ significantly regarding symptom duration, tumor location or stage, H. pylori infection, blood group, or BRCA2 C572T silent mutation status. A comparison of male and female patients aged 40 years or less did not reveal sex-based differences in any analyzed features.Conclusion: Patients ≤40 years of age with GC differ from patient >40 years of age in having a predominance of women, diffuse tumor type, and positive family history of cancer. These results offer openings for further investigation of the relevance of these differences.

Abstract
BACKGROUND Aberrantly expressed mucin glycoproteins (MUC) play important roles in pancreatic ductal adenocarcinoma (PDAC), yet their use as a diagnostic aid in fine-needle aspiration biopsy (FNAB) is poorly documented. The aim of this study was to investigate the rationale and feasibility of mucin (MUC1, MUC2, MUC3, MUC4, MUC5AC, and MUC6) expression profiling by RT-PCR for diagnostic applications in cytology. METHODS Mucin expression was examined by RT-PCR and immunohistochemistry in specimens resected from patients with pancreatic (n = 101), ampullary (n = 23), and common bile duct (n = 10) cancers and 33 with chronic pancreatitis. Furthermore, mucin profiling by RT-PCR was prospectively compared in surgical and biopsy specimens of 40 patients with pancreatic solid tumours qualified for FNAB prior to surgery. RESULTS A logistic regression model to distinguish PDAC from chronic pancreatitis using RT-PCR profiling included MUC3, MUC5AC, and MUC6. The same set of mucins differentiated ampullary and bile duct cancers from chronic pancreatitis. AUCs for the ROC curves derived from the two models were 0.95 (95%CI 0.87-0.99) and 0.92 (95%CI 0.81-0.98), respectively. The corresponding positive likelihood ratios were 6.02 and 5.97, while the negative likelihood ratios were 0.10 and 0.12. AUCs of ROC curves obtained by RT-PCR and immunohistochemistry demonstrated that both analytical methods were comparable. Surgical and cytological samples showed significantly correlated values of ΔCt for individual mucins with the overall Pearson's correlation coefficient r = 0.841 (P = 0.001). CONCLUSIONS Mucin expression profiling of pancreatic cancer with RT-PCR is feasible and may be a valuable help in discriminating malignant lesions from chronic pancreatitis in FNAB cytology.

Abstract
BACKGROUND Immunomodulating enteral nutrition in the perioperative period may reduce postoperative complications in cancer patients. Little is known if this effect translates to the better survival. The aim of study was to assess the impact of postoperative immunomodulating enteral nutrition on postoperative complications and survival of gastric cancer patients. METHODS A group of 98 gastric cancer patients was randomly assigned for postoperative immunomodulating enteral nutrition n = 44 (Reconvan, Fresenius Kabi, Bad Homburg, Germany), or standard enteral nutrition n = 54 (Peptisorb, Nutricia, Schipol, The Netherlands). Postoperative complications, mortality, 6-mo and 1-yr survival were analyzed. RESULTS The overall postoperative morbidity did not differ between the groups. The rate of pulmonary complications (excluding pneumonia) was significantly lower in immunomodulation group (0% vs 9.3%, p = 0.044), as well as 60-day mortality (0% vs. 11.1%, p = 0.037). There was no difference in 6-mo and 1-yr survival between the groups. CONCLUSIONS Postoperative immunomodulating enteral nutrition may reduce respiratory complications and postoperative mortality in comparison to standard enteral nutrition. Despite this effect, it did not improve 6-mo and 1-yr survival in immunomodulation group. Probably the beneficial effect of immunomodulating enteral nutrition is too weak to be significant in such a number of patients.

Abstract
The "Polish Research on Gastric Cancer" project has been continued since 1986. The main aim of this project, which is a multicenter and interdisciplinary research, is enhancing the treatment results of gastric cancer patients by developing and promoting the use of optimal methods for diagnosis and treatment, both surgical as well as combined. One of the more important achievements of the project is the development and publication of a document named "Polish Consensus on Treatment of Patients with Gastric Cancer", whose first version was published in 1998. Following versions were updated adequately to changing trends in the proceedings in patients with gastric cancer. A scientific symposium on "Polish Consensus on Treatment of Gastric Cancer - update 2016" was held in 3-4 June 2016 in Cracow. During the symposium a panel session was held during which all authors publicly presented the Consensus assumptions to be discussed further. Moreover, the already mentioned session was preceded by a correspondence as well as a working meeting in order to consolidate the position. It has to be underlined that the directions and guidelines included in the Consensus are not the arbitrarily assumed rules of conduct in a legal aspect and as such every doctor/team of doctors is entitled to make different decisions as long as they are beneficial to a patient with gastric cancer. The Consensus discusses as follows: a) recommended qualifications (stage of advancement, pathological, lymph node topography and the extent of lymphadenectomy, division of cancer of the gastroesophageal junction), b) rules for diagnostics including recommendations regarding endoscopic examination and clinical evaluation of the advancement stage, c) recommendations regarding surgical treatment (extent of resection, extent of lymphadenectomy, tactics of proceedings in cancer of the gastroesophageal junction), d) recommendations regarding combined treatment with chemotherapy or radiotherapy, e) place of endoscopic and less invasive surgery in the treatment of gastric cancer. This publication is a summary of the arrangements made in the panel session during the abovementioned scientific symposium in Cracow in 2016.

Abstract
BACKGROUND High stability and disease-specific disarrangements suggest that microRNA molecules (miRNAs) present in body fluids are ideally suited for diagnostic applications, including gastric cancer (GC). However, the actual source of circulating miRNA biomarkers in GC has not been adequately evaluated, particularly in the Western populations that have some distinct characteristics compared with Asian patients. METHODS Twenty treatment-naive patients with GC along with 20 cancer-free controls were recruited. miRCURY LNA miRNA microarrays were used for miRNA expression profiling in primary tumours and adjacent healthy mucosa. Differentially expressed serum miRNAs were identified with a high throughput TaqMan OpenArray technology in tumour-draining veins of the portal system, as well as peripheral blood of the patients and controls. RESULTS Tissue profiling identified 108 sequences differentially expressed between primary tumours and adjacent mucosa (87 upregulated and 21 downregulated). Twenty miRNAs found in serum of GC patients showed expression levels higher than in controls. However, only seven of these molecules were overexpressed in primary tumours (miR-130a, miR-331, miR-19a, miR-223, miR-106a, miR-21, and miR-374). Moreover, expression of miR-331 and miR-21 was significantly higher in the peripheral circulation compared to tumour-draining veins of the portal system. CONCLUSIONS The results indicate that the majority of potential serum miRNA biomarkers may originate from tissues other than the primary tumour.

Abstract
After more than a decade of biomarker discovery using advanced proteomic and genomic approaches, very few biomarkers have been involved in clinical diagnostics. Most candidate biomarkers are focused on the protein component. Targeting post-translational modifications (PTMs) in combination with protein sequences will provide superior diagnostic information with regards to sensitivity and specificity. Glycosylation is one of the most common and functionally important PTMs. It plays a central role in many biological processes, including protein folding, host-pathogen interactions, immune response, and inflammation. Cancer-associated aberrant glycosylation has been identified in various types of cancer. Expression of cancer-specific glycan epitopes represents an excellent opportunity for diagnostics and potentially specific detection of tumors. Here, we report four proteins (LIFR, CE350, VP13A, HPT) found in sera from pancreatic cancer patients carrying aberrant glycan structures as compared to those of controls.

BACKGROUND Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR) may serve as a simple index of the immune function. The aim of this study was to investigate the prognostic significance of NLR, PLR, and LMR in patients with resectable pancreatic ductal adenocarcinoma (PDAC) and to verify whether such biomarkers are associated with changes in populations of lymphoid cells. METHODS The prognostic implications of blood count parameters were evaluated in a retrospective cohort of 442 subjects undergoing pancreatic resections for PDAC. Subpopulations of lymphocytes and monocytes in peripheral blood were identified by FACS in a prospective cohort of 54 patients. RESULTS In the univariate analysis, NLR < 5 and LMR ≥ 3 were associated with significantly longer median survival of 25.7 vs 12.6 months and 29.2 vs 13.1 months, respectively. PLR did not influence survival. The Cox proportional hazards model showed that high NLR (HR 1.66, 95 % CI 1.12 to 2.46, P = 0.012) and low LMR (HR 1.65, 95 % CI 1.06 to 2.58, P = 0.026) were independent predictors of poor prognosis. NLR ≥ 5 and LMR < 3 correlated with an approximately twofold decrease in counts of helper and cytotoxic T cells, B cells, and NK cells. High NLR was also accompanied with increased neutrophil counts, while low LMR showed increased numbers of monocytes, mostly classical. CONCLUSIONS NLR and LMR may carry important prognostic information for patients with resected PDAC. The unfavorable prognosis likely correlates with reduced numbers of immune cells effective against the tumor and increased populations of cells involved in immune suppression.

Abstract
AIMS Mucin (MUC) glycoproteins are involved in various steps of the carcinogenesis and progression of human malignancies. The aim of this study was to verify whether semiquantitative evaluation of MUC staining by immunohistochemistry may help to differentiate pancreatic ductal cell adenocarcinoma (PDAC) from chronic pancreatitis and normal pancreas. METHODS AND RESULTS Mucin expression was examined by immunohistochemistry in surgical specimens resected from 101 patients with PDAC and 33 with chronic pancreatitis, and in 40 normal pancreatic tissue specimens. A quickscore (QS, range 0-300) was calculated by multiplying staining intensity by the percentage of positive cells. A diagnostic model was developed for MUC QS (MUC1, MUC2, MUC3, MUC4, MUC5AC, and MUC6), based on a receiver operating characteristic (ROC) curve and logistic regression analysis. Median QS values for MUC1 and MUC5AC were significantly higher for PDAC, whereas patients with non-malignant tissues had higher values for MUC3 and MUC6. The area under the curve for the ROC curve derived from the diagnostic model including MUC3, MUC5AC and MUC6 was 0.96 [95% confidence interval (CI) 0.91-0.98], with 85% sensitivity and 94% specificity. Median QS values for MUC2 were significantly higher in patients with less advanced tumours, whereas venous invasion was associated with a lower QS for MUC6. Moreover, multivariate survival analysis revealed that low MUC6 expression was a negative prognostic factor, with a hazard ratio of 1.73 (95% CI 1.07-2.81). CONCLUSIONS The three-MUC diagnostic model (MUC3, MUC5AC, and MUC6) showed an excellent ability to discriminate pancreatic cancer from non-malignant tissues, and yielded information that may prove useful for the development of clinical applications.

Abstract
Background Most pancreatoduodenectomy resections do not meet the minimum of 12 lymph nodes recommended by the American Joint Committee on Cancer for accurate staging of periampullary malignancies. The purpose of this study was to investigate factors affecting the likelihood of adequate nodal yield in pancreatoduodenectomy specimens subject to routine pathological assessment. Methods Six hundred sixty-two patients subject to pancreatoduodenectomy between 1990 and 2013 for pancreatic, ampullary, and common bile duct cancers were reviewed. Predictors of yielding at least 12 lymph nodes were evaluated with a logistic regression model, and a survival analysis was carried out to verify the prognostic implications of nodal counts. Results The median number of evaluated nodes was 17 (interquartile range 11 to 25), and less than 12 lymph nodes were reported in surgical specimens of 179 (27 %) patients. Tumor diameter ≥20 mm (odds ratio [OR] 2.547, 95 % confidence interval [CI] 1.225 to 5.329, P = 0.013), lymph node metastases (OR 2.642, 95 % CI 1.378 to 5.061, P = 0.004), and radical lymphadenectomy (OR 5.566, 95 % CI 2.041 to 15.148, P = 0.01) were significant predictors of retrieving 12 or more lymph nodes. Lymph node counts did not influence the overall prognosis of the patients. However, a subgroup analysis carried out for individual cancer sites demonstrated that removing at least 12 lymph nodes is associated with better prognosis for pancreatic cancer. Conclusions Few variables affect adequate nodal yield in pancreatoduodenectomy specimens subject to routine pathological assessment. Considering the ambiguities related to the only modifiable factor identified, appropriate pathology training should be considered to increase nodal yield rather than more aggressive lymphatic dissection.

Abstract
One of the methods used to reduce pain and discomfort during colonoscopy is insufflation of carbon dioxide instead of air. However, the actual benefit of carbon dioxide insufflation is not unequivocally proven. The aim of the study was to evaluate the advantages of carbon dioxide insufflation during screening colonoscopy. A total of 200 patients undergoing screening colonoscopy between 2010 and 2011 were included in the prospective, randomized study carried out in a surgical referral center. Screening unsedated colonoscopy with either air or carbon dioxide insufflation was performed; patients were randomly assigned to air or carbon dioxide group by means of computer-generated randomization lists. All examinations were performed in an ambulatory setting with standard videocolonoscopes. The main outcomes analyzed were (a) duration of the entire procedure, (b) cecal intubation time, and (c) pain severity immediately, 15, and 60 min after the procedure. Group I included 59 women and 41 men and group II included 51 women and 49 men. The duration of the procedure was circa 10 min in both groups. Pain score values immediately and 15 min after the procedure were similar in both groups (P=0.624 and 0.305, respectively). A lower pain score was observed only after 60 min in patients insufflated with carbon dioxide (1.28 vs. 1.54, P=0.008). No pain reduction was observed in women and in obese patients (BMI>30). Carbon dioxide insufflation during unsedated screening colonoscopy does not decrease the duration of the procedure and appears to reduce pain intensity at 60 min after examination to an extent without clinical significance. The study was registered at ClinicalTrials.gov, number NCT01461564.

Abstract
INTRODUCTION Chemokines are cytokines with chemotactic functions in the initiation and maintenance of immune reactions. They have also been shown to regulate other processes such as cancer progression and cancer cell migration. OBJECTIVES The aim of this study was to determine the prognostic role of serum levels of chemokine (C-C motif) ligand 2 (CCL2) and chemokine (C-C motif) ligand 5 (CCL5) in patients with colorectal cancer. PATIENTS AND METHODS The study included a group of 45 patients with colorectal cancer. The serum concentrations of CCL2 and CCL5 were measured preoperatively. Peripheral blood mononuclear cells (PBMC) from patients' blood were isolated and cultured alone or with cancer cells. The concentrations of chemokines in serum and culture supernatants were measured using the cytometric bead array method. The cut-off points for serum chemokine levels were set based on the receiver-operating characteristic curve analysis at a level of 103.6 pg/ml for CCL2 and of 11933.2 pg/ml for CCL5. The survival analysis and multivariate analysis of prognostic factors were performed. RESULTS The 5-year survival was 57.5% for the group with low CCL2 levels and 23.87% for the group with high CCL2 levels. For the groups with low and high CCL5 levels, the survival was 18.3% and 49.3%, respectively. For CCL2, the survival of the low-level group was significantly better than that of the highlevel group (P = 0.0028). In the Cox proportional hazard model, radicality of resection (P = 0.001) and CCL2 levels (P = 0.029) were independent prognostic factors. CONCLUSIONS The serum level of CCL2 in patients with colorectal cancer may have prognostic value. One of the possible mechanisms of CCL2 production is the interaction of PBMC with cancer cells.

Abstract
Mondor's disease is a rare, benign condition characterised by thrombophlebitis affecting subcutaneous veins of the chest and/or abdomen without an accompanying inflammatory response. The disease has a multifactorial etiology and its course is benign. It is usually self-limiting or it is eliminated by local treatment. Mondor's disease in the thoracoepigastric region may be a rare complication of mammotome biopsy. The case presentation describes a 32-year-old patient with Mondor's disease in the thoracoepigastric region after an ultrasound-guided mammotome biopsy of a breast. In the histopathological examination the lesion was diagnosed as fibroadenoma. Regardless of the disease's etiology, it is recommended to carry out diagnostic examinations to exclude co-occurring breast cancer.

Abstract
BACKGROUND Little data are available supporting the feasibility and safety of early oral feeding in patients after total gastrectomy. The aim of this study was to analyze the potential applicability of early provision of oral diet in these settings. METHODS Medical records of 353 patients who underwent total gastrectomy for gastric cancer between 2006 and 2012 were retrospectively analyzed. Early oral feeding was defined as clear liquid diet on postoperative day (POD) 1 followed by gradual introduction of solid diet on POD 2 to 3. Late oral feeding was defined as initiation of liquid diet from POD 4 to 6 and gradually advancing to solid diets. RESULTS Early oral feeding was implemented in 185 of 353 (52 %) patients. Prompt provision of food did not increase the risk of anastomotic failure (odds ratio 0.924, 95 % confidence interval 0.609-1.402, P = 0.709). The number of reoperations and in-hospital mortality rates was unaffected by the timing of nutritional intervention. Early feeding tended to be associated with fewer surgical (15 vs 24 %, P = 0.027) and general (8 vs 23 %, P < 0.001) complications. However, subsequent multivariate regression models failed to confirm significant correlations between timing of oral meals and postoperative morbidity. CONCLUSION Our findings suggested that early oral feeding is feasible and safe after total gastrectomy for gastric cancer. However, benefits of such early nutritional interventions require further studies.

Abstract
Proper preparation of the patient for surgery has a crucial impact on the outcome. Due to the continuous increase in life expectancy more and more often the problem of proper perioperative preparation of the patients over 65 years of age burdened with a higher risk of perioperative complications is undertaken. Proper assessment of the health condition and physical capacity allows to optimize treatment and thus minimize the risk of complications. In many countries, the recommended procedure is to perform the Comprehensive Geriatric Assessment (CGA), which, however, due to the need to carry out a number of additional diagnostic tests and consultations is too expensive for the vast majority of hospitals. Therefore the search for more convenient methods of abbreviated assessment is undertaken, the methods that will identify patients at greatest risk of complications. The Comprehensive Geriatric Assessment includes a series of tests and scales assessing, interalia, cognitive functions, motor efficiency, dependency, nutrition and mood. Applied abbreviated methods of perioperative assessment also have limitations in predicting the course of hospitalization. So far, there is no general practice guidelines for patients over 65 years of age. But it seems reasonable to perform the CGA in case of an unfavorable outcome of abbreviated assessment or when the threat of frailty syndrome is suspected. This procedure enables to select the best method of treatment, the implementation of appropriate prevention, thus improving the outcome of treatment and quality of life.

Abstract
Background/objectives: Inflammation is a central process responsible for health outcomes among surgical patients. Immunonutrition has been investigated as a promising modifying factor; however, inflammatory properties of habitual diet have not yet been investigated. The purpose of this study was to describe inflammatory properties of diet measured by the dietary inflammatory index (DII) among surgical patients treated for colorectal cancer and to link inflammatory properties of habitual diet with a duration of hospitalization. Subjects/methods: A follow-up study among colorectal cancer patients treated surgically was performed in Krakow, Poland. In total, 689 patients were recruited for the study. Habitual diet was assessed using a standardized semiquantitative food frequency questionnaire. Overall, 23 dietary items (including macro-and micronutrients) were used to calculate individuals' DII. Gender, age, marital status, body mass index, smoking status, lifetime physical activity, taking vitamin supplements, number of chronic diseases, cancer site, Duke's staging and surgery type were considered as potential covariates. Results: Participants were aged 58 years, with the average hospitalization time of 11 days. Higher DII (meaning diet with higher anti-inflammatory properties) was negatively associated with the duration of hospitalization (univariable linear regression: b=−0.59; P=0.005). Multivariable logistic regression has shown the decrease of the risk of longer stays (>7 days) among patients with the DII >−4.25, but only among younger (⩽60 years) patients, irrespective of Duke's staging. Conclusions: The DII might be used as a potential predictor of longer hospitalization among colorectal cancer patients treated surgically. The study provides evidence for the role of dietary-related low-grade inflammation among surgical patients.

Abstract
INTRODUCTION Various imaging modalities are used for the diagnosis and staging of pancreatic cancer. Abdominal ultrasonography is the most widely available method and usually the first -line diagnostic tool used in patients with suspicion of pancreatic carcinoma. OBJECTIVES The aim of the study was to assess the clinical value of abdominal ultrasonography used in a tertiary center for staging of pancreatic carcinoma. PATIENTS AND METHODS This prospective clinical trial included 454 consecutive patients with pancreatic cancer, who underwent a surgery between 2000 and 2012. The diagnostic accuracy of ultrasonography was established for each T category and lymph node involvement. Computed tomography and intraoperative staging of the pancreatic cancer were used as reference methods. RESULTS The diagnostic accuracy of ultrasonography in cancer staging according to T categories was 94.1% for T1, 95.7% for T2, 85.4% for T3, and 81.7% for T4 tumors. The diagnostic accuracy of abdominal ultrasonography in the diagnosis of lymph node metastasis and assessment of tumor resectability was 66.1% and 74.8%, respectively. CONCLUSIONS The results of our study summarize 12 years of our experience with abdominal ultrasonography in patients with pancreatic cancer and confirm that ultrasonography remains a valuable diagnostic modality in this patient group.

Abstract
Pentraxins are among the main acute phase reactants. There are two types of pentraxins, i.e., long, including pentraxin 3 (PTX3) and short, including C-reactive protein (CRP) and serum amyloid A (SAA). The aim of the study was to assess the increase in serum concentrations of pentraxins (ex- pressed as the multiplicity of the upper reference limits) and their usefulness in prognosing severe course of acute pancreatitis (AP) in the early phase of the disease. Forty patients admitted to Ist Department of Surgery, Jagiel-Ionian University Medical College with the diagnosis of AP were recruited for the study. In the early phase of AP, the concentrations of PTX3 achieved maximum earlier than CRP or SAA, enabling to differentiate between mild and moderate or severe AP in the first day of the disease. Also, during the first 24 hours from beginning of AP, SAA achieved its best prognostic value. Of all pentraxins studied, SAA was characterized by the most significant increase as compared to the upper reference limit. The prognostic utility of CRP increased later, after 48 hours of AP.

Abstract
AIM Our aim was to determine serum concentrations of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its decoy receptor osteoprotegerin (OPG) in patients with mild and moderate to severe acute pancreatitis (AP) in the early phase of the disease. MATERIALS AND METHODS We included 40 patients with AP (16 women, 24 men) admitted to Ist Department of Surgery, Jagiellonian University Medical College, Krakow. Twenty-eight had mild (MAP) and twelve moderate to severe form of AP (SAP). Serum concentrations of OPG and TRAIL were measured by ELISA at admission and on days 3, 5 and 7. RESULTS Both TRAIL and OPG were elevated in AP patients as compared to reference values. Starting from day 3 of the study, OPG concentrations were significantly higher in SAP than in MAP. Also, day 3 OPG was higher in patients who died from AP. OPG positively correlated with Glasgow score, C-reactive protein (CRP) concentrations and length of hospital stay. Day 3 OPG cut-off of 713 pg/mL enabled to differentiate between SAP and MAP with sensitivity of 71% and specificity of 80%. Area under ROC curve was 0.795, comparable to that achieved for CRP (0.838; p >0.05). In contrast, serum concentrations of TRAIL were not associated with AP severity. CONCLUSIONS Determination of serum OPG concentrations may help in early prediction of severity of AP. However, diagnostic utility of the measurements seems too low to use OPG as a single clinically reliable predictor. Serum TRAIL is not useful in the differentiation between mild and severe form of AP.

Abstract
Peripheral blood count belongs to the most frequently ordered laboratory tests performed in the assessment of the current patients condition. In addition to basic information, including analysis of individual cell populations, additional parameters are given that can be helpful in predicting the course of disease, including acute pancreatitis (AP). The aim of the study was to compare the parameters of blood counts in patients with mild and moderate to severe AP in the early stage of the disease. We confirmed a significant predictive value of monitoring the total white blood cell counts, direct neutrophil counts, platelet counts, and the value of RDW in the first week of AP. Also, the relationship was observed between increased hematocrit value and mortality in patients with severe acute pancreatitis.

Abstract
AIM To investigate large tumor suppressor 1 (LATS1) expression, promoter hypermethylation, and microsatellite instability in colorectal cancer (CRC). METHODS RNA was isolated from tumor tissue of 142 CRC patients and 40 colon mucosal biopsies of healthy controls. After reverse transcription, quantitative polymerase chain reaction (PCR) was performed, and LATS1 expression was normalized to expression of the ACTB and RPL32 housekeeping genes. To analyze hypermethylation, genomic DNA was isolated from 44 tumor CRC biopsies, and methylation-specific PCR was performed. Microsatellite instability (MSI) status was checked with PCR using BAT26, BAT25, and BAT40 markers in the genomic DNA of 84 CRC patients, followed by denaturing gel electrophoresis. RESULTS Decreased LATS1 expression was found in 127/142 (89.4%) CRC cases with the average ratio of the LATS1 level 10.33 ± 32.64 in CRC patients vs 32.85 ± 33.56 in healthy controls. The lowest expression was found in Dukes' B stage tumors and G1 (well-differentiated) cells. Hypermethylation of the LATS1 promoter was present in 25/44 (57%) CRC cases analyzed. LATS1 promoter hypermethylation was strongly associated with decreased gene expression; methylated cases showed 162× lower expression of LATS1 than unmethylated cases. Although high-grade MSI (mutation in all three markers) was found in 14/84 (17%) cases and low-grade MSI (mutation in 1-2 markers) was found in 30/84 (36%) cases, we found no association with LATS1 expression. CONCLUSION Decreased expression of LATS1 in CRC was associated with promoter hypermethylation, but not MSI status. Such reduced expression may promote progression of CRC.

Abstract
The aim of this study was to assess the presence of interstitial Cajal-like cells (ICLCs) in the human gallbladder and to determine their distinctive characteristics on the basis of double immunohistochemical staining. Gallbladder specimens were obtained from 30 patients subjected to elective laparoscopic cholecystectomy for symptomatic gallstone disease. Tissue samples were fixed in 4% phosphate-buffered paraformaldehyde, processed, embedded in paraffin, and, after sectioning, routinely stained with HE. Tissue antigens were retrieved using the heat-induced epitope retrieval (HIER) method. For simultaneous visualisation of two antigens, an indirect double immunofluorescence procedure was applied. ICLCs were defined as CD117-immunopositive and tryptase-immunonegative objects. They were predominantly fusiform in shape with sparse branches that were visible in some sections. ICLCs were observed throughout the organ including the gallbladder's fundus, body (corpus) and neck, being most numerous in the corpus. The ICLCs were detected almost exclusively within the muscularis propria and they were arranged parallel to smooth muscle cells. The following subpopulations of ICLCs were observed: ICLC-IM (intramuscular ICLCs) localised between smooth muscle fibres forming one muscle bundle; and ICLC-IB (interbundle ICLCs) localised within the connective tissue separating smooth muscle bundles. Thus, the presence of ICLCs in the human gallbladder was clearly identified, demonstrated by double immunohistochemistry which was found to be a reliable method for differentiating ICLCs from mast cells.

Abstract
The major mechanisms of gallstone formation include biliary cholesterol hypersecretion, supersaturation and crystallization, mucus hypersecretion, gel formation and bile stasis. Gallbladder hypomotility seems to be a key event that triggers the precipitation of cholesterol microcrystals from supersaturated lithogenic bile. Telocytes, a new type of interstitial cells, have been recently identified in many organs, including gallbladder. Considering telocyte functions, it is presumed that these cells might be involved in the signalling processes. The purpose of this study was to correlate the quantity of telocytes in the gallbladder with the lithogenicity of bile. Gallbladder specimens were collected from 24 patients who underwent elective laparoscopic cholecystectomy for symptomatic gallstone disease. The control group consisted of 25 consecutive patients who received elective treatment for pancreatic head tumours. Telocytes were visualized in paraffin sections of gallbladders with double immunofluorescence using primary antibodies against c-Kit (anti-CD117) and anti-mast cell tryptase. Cholesterol, phospholipid and bile acid levels were measured in gallbladder bile. The number of telocytes in the gallbladder wall was significantly lower in the study group than that in the control group (3.03 ± 1.43 versus 6.34 ± 1.66 cell/field of view in the muscularis propria, P < 0.001) and correlated with a significant increase in the cholesterol saturation index. The glycocholic and taurocholic acid levels were significantly elevated in the control subjects compared with the study group. The results suggest that bile composition may play an important role in the reduction in telocytes density in the gallbladder.

Abstract
PURPOSE To assess local control after preoperative radiation and local excision and to determine an optimal radiotherapy regimen. METHODS Eighty-nine patients with G1-2 rectal adenocarcinoma <3-4 cm; unfavourable cT1N0 (23.6%), cT2N0 (62.9%) or borderline cT2/cT3N0 (13.5%) received 5 × 5 Gy plus 4 Gy boost (71.9%) or 55.8 Gy in 31 fractions with 5-FU and leucovorin (28.1%). Local excision (traditional technique 56.2%, transanal endoscopic microsurgery 41.6%, Kraske procedure 2.2%) was performed 6-8 weeks later. If patients were downstaged to ypT0-1 without unfavourable factors (good responders), this was deemed definitive treatment. Immediate conversion to radical surgery was recommended for remaining patients. RESULTS Good response to radiation was seen in 67.2% of patients in the short-course group and in 80.0% in the chemoradiation group, p = 0.30. Local recurrence at 2 years (median follow-up) in good responders was 11.8% in the short-course group and 6.2% in the chemoradiation group, p = 0.53. In the total group, a lower rate of local recurrence at 2 years was observed in elderly patients (>69 years, median value) when compared to the younger patients; 8.3% vs. 27.7%, Cox analysis hazard ratio 0.232, p = 0.016. A total of 18 patients initially managed with local excision required conversion to abdominal surgery but either refused it or were unfit. In this group, local recurrence at 2 years was 37.1%. CONCLUSIONS This study suggests an acceptable local recurrence rate after preoperative radiotherapy and local excision of small, radiosensitive tumours in elderly patients.

Abstract
AIM The aim of this study was to assess the diagnostic value of hepatocyte growth factor (HGF) as a new predictor of severity in patients with acute pancreatitis (AP) at early phase of disease. MATERIALS AND METHOD The studied group involved 40 patients (16 women and 24 men) with AP admitted to Ist Dept. of Surgery Jagiellonian University Medical College in Krakow. Twenty-four patients had mild and twelve severe form of AP. Glasgow and Imrie scores were calculated to evaluate severity of AP. HGF concentrations were measured by ELISA (R&D Systems) on days 1, 3 and 5 after admission within 48 hours after onset of symptoms. RESULTS Serum median concentrations of HGF was significantly higher in patients with severe versus mild clinical course of AP on each of the study days (7.61 vs 3.30 ng/mL, p = 0.05 on day 1; 7.19 vs 3.43, p = 0.04 on day 3 and 5.76 vs 2.42, p = 0.02 on day 5). HGF positively correlated with Glasgow and Imrie scores (R = 0.57 and R = 0.51). HGF negatively correlated with fetuin A, a negative acute phase protein (R = -0.60 on day 3 and R = -0.45 on day 5) and positively with CRP (R = 0.93; R = 0.80), SAA (R = 0.78; R = 0.82), IL-6 (R = 0.61; R = 0.77; R = 0.85 on day 1, 3 and 5, respectively) and PMN-elastase (R = 0.58; R = 0.64; R = 0.77). On day 1 of the study, HGF reached the diagnostic sensitivity of 100% and specificity of 50% for the detection of severe and moderate AP. CONCLUSIONS Serum HGF correlates with several inflammatory markers and clinical scores (Glasgow, Imrie) in patients with AP and may be considered a new promising tool in assessing the severity of acute pancreatitis.

Abstract
During last decade, many new biomarkers have been proposed for early diagnosis of acute pancreatitis and prognosis of its severity. However clinical availability of many markers are limited due to costly and time. consuming laboratory methods used, for their assessment, including ELISA technique. Recent studies revealed the usefulness of red cell distribution width (RDW), as a predictor of unfa vorable prognosis in many disease states. RDW is an easily available index generated automatically as a part of standard complete blood count In our group of 40 acute pancreatitis patients, RDW values assessed du ring first 5 days of disease, correlated positively with the duration of hospital stay and the severity of disease as well as with the concentration of selected inflammatory markers. Patients who died had significantly higher RDW comparing to survivors. Our results indicate that RDW may be helpful in early prediction of clinical course of acute pancreatitis.

Abstract
Despite new diagnostic methods, including novel laboratory parameters and imaging techniques, and growing knowledge on pathogenesis of acute pancreatitis, early assessment of severity remains the main factor influencing prognosis in the disease. The aim of the study was the evaluation of diagnostic accuracy of interleukins (IL): 6 and 18 and acute phase proteins: C-reactive protein (CRP) and serum amyloid A (SAA), together with Glasgow prognostic score during first 48 hours after diagnosing acute pancreatitis in a group of 40 patients treated in the I-st Department of General and Gastrointestinal Surgery University Hospital in Cracow. All the studied inflammatory markers were significantly higher in patients with moderate and severe acute pancreatitis versus patients with mild form of the disease on the first 48 hours of the disease. Expanding Glasgow score with IL-6, IL-18, SAA or CRP determinations resulted in better accuracy for diagnosing severe clinical course of acute pancreatitis.

Abstract
BACKGROUND Little data are available for non-abscess abdominal fluid collections (AFCs) after pancreatic surgery and their clinical implications. We sought to analyze the natural history of such collections in a population of patients subject to routine postoperative imaging. METHODS From 1995 to 2011, 709 patients underwent pancreatic resections and routine postoperative monitoring with abdominal ultrasound according to a unit protocol. AFCs were classified as asymptomatic (no interventional treatment), symptomatic (need for percutaneous drainage of sterile, amylase-poor fluid), and pancreatic fistula (drainage of amylase-rich fluid). RESULTS Ninety-seven of 149 AFCs (65 %) were asymptomatic and resolved spontaneously after a median follow-up of 22 days (interquartile range, 9-52 days). Among 52 (35 %) AFCs requiring percutaneous drainage, there were 20 pancreatic fistulas and 32 symptomatic collections. A stepwise logistic regression model identified three factors associated with the need for interventional treatment, i.e., body mass index ≥25 (odds ratio, 3.23; 95 % confidence interval (CI), 1.32 to 7.91), pancreatic fistula (odds ratio, 2.93; 95 % CI, 1.20 to 7.17), and biliary fistula (odds ratio, 3.92; 95 % CI, 1.35 to 11.31). CONCLUSIONS One fourth of patients develop various types of non-abscess AFCs after pancreatic surgery. Around half of them are asymptomatic and resolve spontaneously.

Abstract
BACKGROUND Interstitial cells of Cajal (ICCs) play an important role in the regulation of gut motility. There is growing evidence that interstitial Cajal-like cells (ICLCs) are present in the gallbladder wall. We hypothesize that changes in the density of ICLCs in the gallbladder wall may lead to the development of cholelithiasis due to the impairment of the gallbladder motility. The purpose of this study was to identify ICLCs in the gallbladders of patients with gallstones and to assess their densities. METHODS Data from 30 patients with gallstones and 25 individuals without gallstones were compared. Tissue samples were obtained during surgery, embedded in paraffin, and cut into sections. Following staining for CD117 and mast cell tryptase, the number of ICLCs and mast cells was determined using image analysis. KEY RESULTS Cells positive for the c-Kit receptor (CD117) were detected in the gallbladder wall in all cases examined. Interstitial Cajal-like cells were most frequently observed in the muscularis propria. The density of ICLCs in the muscularis propria was significantly lower in the patients with gallstones than the density observed in the controls (26.24 ± 10.89 vs 56.29 ± 13.35 cells/mm(2)). In contrast, the number of mast cells in the gallbladder was increased in the patients with gallstones when compared with the controls (143 ± 24 vs 112 ± 19 cells/mm(2)). CONCLUSIONS & INFERENCES The histopathological differences observed in this study may help elucidate the pathophysiology of gallstones. Gallbladder motility may be affected by the decreased number of ICLCs in patients with cholelithiasis.

Abstract
PURPOSE The objective of this article is to present a new method for the diagnosis of insulinoma with the use of [Lys(40)(Ahx-HYNIC-(99m)Tc/EDDA)NH2]-exendin-4. METHODS Studies were performed in 11 patients with negative results of all available non-isotopic diagnostic methods (8 with symptoms of insulinoma, 2 with malignant insulinoma and 1 with nesidioblastosis). In all patients glucagon-like peptide-1 (GLP-1) receptor imaging (whole-body and single photon emission computed tomography/CT examinations) after the injection of 740 MBq of the tracer was performed. RESULTS Both sensitivity and specificity of GLP-1 receptor imaging were assessed to be 100 % in patients with benign insulinoma. In all eight cases with suspicion of insulinoma a focal uptake in the pancreas was found. In six patients surgical excision of the tumour was performed (type G1 tumours were confirmed histopathologically). In one patient surgical treatment is planned. One patient was disqualified from surgery. In one case with malignant insulinoma pathological accumulation of the tracer was found only in the region of local recurrence. The GLP-1 study was negative in the other malignant insulinoma patient. In one case with suspicion of nesidioblastosis, a focal accumulation of the tracer was observed and histopathology revealed coexistence of insulinoma and nesidioblastosis. CONCLUSION [Lys(40)(Ahx-HYNIC-(99m)Tc/EDDA)NH2]-exendin-4 seems to be a promising diagnostic tool in the localization of small insulinoma tumours, but requires verification in a larger series of patients.

Abstract
BACKGROUND The aim of this study was to assess the value of mammographically-guided and ultrasonographically-guided vacuum-assisted core biopsy (VACB) in the diagnosis and treatment of intraductal papillomas of breast and to answer the question of whether biopsy with the Mammotome (Mammotome; Cincinnati, OH) allows the avoidance of surgery in these patients. PATIENTS AND METHODS In the period 2000 to 2010, a total of 1896 vacuum-assisted core biopsies were performed, of which 1183 were ultrasonographically guided and 713 were mammographically guided (stereotaxic). RESULTS In 62 patients (3.2%) histopathologic examination confirmed intraductal papilloma, and in 12 patients (19.4%) atypical lesions were also found. Open surgical biopsy specimens revealed invasive cancer in 2 women these 12 women (false-negative rate, 16.7%; negative predictive value, 83.3%). Biopsy specimens from the remaining 50 patients (80.6%) revealed papilloma without atypia, and further clinical observation and imaging examinations did not show recurrence or malignant transformation of lesions. Hematoma developed in 3 (4.8%) patients as a complication of biopsy; surgical intervention was not required in any of the patients. CONCLUSION VACB is a minimally invasive and efficient method for diagnosing intraductal papilloma of the breast. If histopathologic examination confirms a benign lesion and corresponds to the clinical presentation, surgery may be avoided. However in all cases, histopathologic diagnosis of papilloma with atypical hyperplasia or a suspected malignant lesion in imaging examinations, despite negative biopsy results, should always be an indication for surgical excision.

Abstract
A 43-year-old man was admitted to Surgery Department because of abdominal pain, vomiting, weight loss and flushes. Computed tomography (CT) examination revealed upper and middle abdomen tumor of about 110 × 110 mm. Histopathological analysis of the tissues obtained during the exploratory laparotomy confirmed WDNT (well-differentiated neuroendocrine tumor according to the WHO classification 2000). The patient received 5 doses of chemotherapy without any response. A positive result of 99mTc-[EDDA/Hynic] Octreotate scintigraphy (SRS) gave the possibility of PRRT (peptide receptor radionuclide therapy). The patient was treated with the total dose of 400 mCi of 90Y-DOTA-TATE. CT performed after the PRRT revealed regression of the tumor size to 72 × 94 mm. A decrease of CgA level and release of symptoms were also observed. Aiming at the removal of the considerable diminished tumor the patient was qualified for the second laparotomy. "Cytoreduction" surgery with partial excision of the tumor was performed. Additionally tumor-affected appendix was removed. The second focus of WDNT (according to the WHO classification 2000) with Ki67 < 1% was found in the appendix. Pathologists confirmed the above-mentioned lesions as independent (an extremely rare clinical situation). The following treatment with long-acting somatostatin analogs and 300 mCi of 90Y-DOTA-TATE resulted in further regression of the tumor size to 25 × 35 mm. Consecutive laparotomy is considered. If complete tumor removal might be achieved is an open question. The above case report shows the efficacy of combined therapy with the use of "hot" and "cold" somatostatin analogs not only in controlling the symptoms of the disease but also in obtaining tumor size regression making surgical intervention possible. Such a neoadjuvant therapy seems to be a promising tool in the management of patients with initially inoperable neuroendocrine tumors.

Abstract
In patients with metastatic gastric cancer, median overall survival remains under 1 year and standard chemotherapy regimens are not able to substantially improve the prognosis of the patients. Amplification and over-expression of HER2 is reported in approximately 20% of gastric tumours, challenging the use of targeted therapies. There are several targeted therapies in different stages of clinical development with trastuzumab being the first overcoming the regulatory hurdle and getting European Medicines Agency approval. In patients with advanced gastric or gastro-oesophageal junction cancer, addition of trastuzumab to chemotherapy significantly improved overall survival compared with chemotherapy alone. Addition of trastuzumab to chemotherapy did not increase the incidence of adverse events. Other agents targeting the HER2 pathway (lapatinib) or other domains of epidermal growth factor receptor family (cetuximab) are currently being investigated for the treatment of an advanced gastric cancer.

Abstract
BACKGROUND Metastatic gastric cancer remains a significant problem as the majority of Western patients are diagnosed with disseminated disease and no routine therapeutic regimen is accepted in such cases. METHODS A cohort of 3141 patients with gastric cancer operated between 1990 and 2005 was evaluated using a multicenter data set held by the Polish Gastric Cancer Study Group to determine potential risks and benefits of non-curative gastrectomy for metastatic disease. Additionally, parameters of Quality of Life (QoL) were evaluated prospectively in 140 patients undergoing gastrectomy using the QLQ-C30 questionnaire. RESULTS Gastrectomy was carried out in 2258 patients. Distant organ metastases were diagnosed in 951 patients, 415 of which underwent non-curative gastrectomy. The overall mortality rates were significantly higher in patients undergoing non-resectional surgery (10%) than either curative (3%, P < 0.001) or non-curative (4%, P = 0.002) gastrectomy. The overall median survival in patients with metastatic disease was significantly higher for non-curative gastrectomy (10.6 months, 95% confidence interval (CI) 9.3-11.9) than for non-resective operations (4.4 months, 95% CI 4.0 to 4.8, P < 0.001). The hazard ratio of death in patients subject to non-resectional surgery compared to those treated by gastrectomy was 2.923 (95% CI 2.473 to 3.454, P < 0.001). A gradual impairment in QoL parameters was found over 12 months after non-curative resections but changes did not reach statistical significance and individual parameters were similar to gastrectomy without distant metastases. CONCLUSION Non-curative gastrectomy for metastatic gastric cancer is associated with significantly better survival compared to non-resective surgery and does not impair quality of life.

Abstract
Nesidioplastosis in adults is one of a rare causes of hyperinsulinemic hypoglycemia. Symptoms include chronic or recurrent hypoglycemias, often with neurological signs. Due to the looses of consciousness with coexisting seizures, in many cases patients are treated on epilepsy. Right diagnosis is usually late established, when the damages in the central nervous system (CNS) are irreversible. Early diagnosis of the disease and appropriate treatment might help to avoid serious disability in these patients. The aim of the study was to asses modern diagnostics of the nesidioblastosis with an emphasis on the biochemical and hormonal tests and imaging modalities. Patients enrolled to the study were aged between 18 and 72 years of age, and had chronic or recurrent hypoglycemia caused by hyperinsulinemia. In all patients fasting glucose and fasting insulinemia tests were performed, as well as the fasting blood test or in the 24-hour profile tests. Several techniques were used including ultrasound (US), abdominal computer tomography (CT), in two patients magnetic resonance imaging, scintigraphy of somatostatin receptors in seven patients, and in two patients scintigraphy with glucagone-like peptide-1 (GLP-1) analogue-labeled marker was done. In the performed tests low values of the blood glucose were found, whereas insulin levels, however not adequate to the blood glucose, were nearly always within the normal range. In the standard imaging only in one patient tumor lesion in the pancreatic tail was revealed, though not confirmed in the intraoperative histology. In the scintigraphy examination with the somatostatin analogue in one patient slightly increased collection of the marker in whole pancreas was reported and in the other patient focal collection in the pancreatic tail was observed. Scintigraphy with GLP-1 analogue revealed focal collection of the marker in one case. Five patients were underwent surgical treatment. In the histopathology in all operated patients hyperplasia of the endocrine pancreatic cells with positive immuno. histochemic reaction on the insulin was found. In the three cases despite hyperplasia of pancreatic islets, small sizes insulinomas were detected as well. 1. The diagnosis of nesidioblastosis should be taken into consideration in all patients with unclear-cause hypoglycemias, in whom simultaneously insulin blood level is inadequate to the level of glucose. 2. Widely available imaging examinations: US, CT, MRI are useless in the diagnosis of nesidioblastosis. 3. Among the imaging methods in preoperative diagnostics of hypoglycemia with concomitant hyperinsulinemia somatostatin receptor scintigraphy seems to have specific, though limited role - it is valuable only in the severe, diffused lesions. 4. Recurrent hypoglycemias after 70% excision of the pancreas may indicate the possibility of coexistence of pancreatic islets hyperplasia and insulin secreting insulinoma.

Abstract
Purpose The purpose of this study was to establish the influence of time interval between preoperative hyperfractionated radiotherapy (5 × 5 Gy) and surgery on long-term overall survival (5 years) and recurrence rate in patients with locally advanced rectal cancer operated on according to total mesorectal excision technique. Methods The treatment group comprised 154 patients with locally advanced rectal cancer who were operated on between 1999 and 2006 in the 1st Department of General Surgery, Jagiellonian University, Cracow, Poland. The data on survival has been systematically collected until 31st of December 2010. In addition, the following aspects were analyzed: the significance of time interval between the end of radiotherapy and surgical treatment and its influence on downsizing, downstaging, rate of curative resections, and sphincter-sparing procedures. Patients were qualified to preoperative radiotherapy 5 × 5 Gy and then randomly assigned to subgroups with different time intervals between radiotherapy and surgery: one subgroup consisted of 77 patients operated on 7–10 days after the end of irradiation, and the second subgroup consisted of 77 patients operated on after 4–5 weeks. Both groups were homogenous in sex, age, cancer stage and localization, distal and circumferential resection margins, and number of resected lymph nodes. Results The 5-year survival rate in patients operated on 7–10 days after irradiation was 63%, whereas in those operated on after 4–5 weeks, it was 73%—the difference was not statistically significant (log rank, p = 0.24). A statistically significant increase in 5-year survival rate was observed only in patients with downstaging after radiotherapy—90% in comparison with 60% in patients without response to neoadjuvant treatment (log rank, p = 0.004). Recurrence was diagnosed in 13.2% of patients. A lower rate of systemic recurrence was observed in patients operated on 4–5 weeks after the end of irradiation (2.8% vs. 12.3% in the subgroup with a shorter interval, p = 0.035). No differences in local recurrence rates were observed in both subgroups of irradiated patients (p = 0.119). The longer time interval between radiotherapy and surgery resulted in higher downstaging rate (44.2% vs. 13% in patients with a shorter interval, p = 0.0001) although it did not increase the rate of sphincter-saving procedures (p = 0.627) and curative resections (p = 0.132). Conclusions Improved 5-year survival rate is observed only in patients with downstaging after preoperative irradiation dose of 25 Gy. Longer time interval after preoperative radiotherapy 25 Gy does not improve the rate of sphincter-saving procedures and curative resections (R0) despite higher downstaging rate observed in this regimen.
