RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Pentraxin 3 (PTX3) belongs to the acute phase proteins; its concentration increases significantly in the early stages of inflammation. In nearly 20% of patients with acute pancreatitis (AP) escalated inflammation leads to the development of severe forms of the disease. The aim of this study was to evaluate the pattern of changes in PTX3 concentration in patients with AP at the early stage of the disease (first 5 days from admission) and to assess the relationship between PTX3 and other inflammatory markers. METHODS: The study included 40 patients with AP (16 women and 24 men)--12 with severe and 28 with mild form of AP. Concentrations of PTX3, serum amyloid A (SAA), C-reactive protein (CRP), hepatocyte growth factor (HGF), procalcitonin (PCT), polymorphonuclear elastase (PMN-elastase), interleukin 6 (IL-6), interleukin 18 (IL-18), and soluble receptor for TNFalpha (sTNFR75) were measured in samples collected on the 1st, 3rd, and 5th day of the hospital stay. Plasma PTX3 was measured also in the control group, consisting of 37 age and sex-matched healthy subjects. RESULTS: The highest concentrations of PTX3 were noted on the first day after admission. The concentrations were higher in patients with the severe compared to those with the mild form of AP (median 17.2 vs. 4.0 ng/mL on day 1, p = 0.03; 6.1 vs. 2.2 on day 5, p = 0.044). On each of the study days significant correlations were found between PTX3 and SAA, IL-6, and PMN-elastase (p < 0.05). CONCLUSIONS: The pattern of changes in PTX3 concentration in the early phase of AP is similar to that of IL-6, and its peak levels are achieved earlier compared to CRP. Our findings suggest that PTX3 may be useful in early evaluation and prediction of the severity of AP.

RESUMO

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.

RESUMO

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.

RESUMO

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.
