Upper endoscopy in elderly patients: a multicentre, cross-sectional study. Ir J Med Sci 2024:10.1007/s11845-024-03774-7. [PMID: 39186194 DOI: 10.1007/s11845-024-03774-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Accepted: 07/31/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND Both macroscopic and histological lesions are frequently detected at upper endoscopy in elderly patients. We assessed the prevalence of main endoscopic and histological alterations in elderly (> 65 years old) patients. METHODS In this study, clinical, endoscopic and histological features of patients referred for upper endoscopy in clinical practice were retrieved. Both univariate and multivariate analyses were executed. Comparisons with previous data were performed. RESULTS A total of 1336 underwent upper endoscopy in the 28 participating centres. At endoscopy, at least one macroscopic lesion was present in overall 420 (31.4%) patients. Erosive gastritis (13.3%) and erosive oesophagitis (9.8%) were the most prevalent lesions, whilst Barrett's oesophagus, gastric ulcer, duodenal ulcer and erosive duodenitis were observed in 1.8%, 2%, 1.4% and 3.1% patients, respectively. Nine (0.6%) cases of oesophageal, 25 (1.8%) gastric and 2 (0.1%) duodenal neoplasia were detected. At histology, Helicobacter pylori infection was diagnosed in 99 (15.9%) patients, and extensive precancerous lesions on gastric mucosa were detected in 80 (14.5%) patients. Endoscopic lesions were more frequent in males, at first endoscopy and in those with alarm symptoms and lower during PPI therapy. At multivariate analysis, PPI therapy significantly reduced the probability of finding endoscopic lesions (OR: 0.68, 95% CI: 0.46-0.99; P = 0.04), whilst neoplastic lesions were associated with presence of alarm symptoms (OR: 1.5, 95% CI: 1.1-2.1; P = 0.005). CONCLUSIONS We found that the frequency of erosive and neoplastic lesions remained high in elderly patients, whilst the prevalence of both H. pylori infection and peptic ulcer was decreased.

Nomogram for predicting the likelihood of liver metastases at initial diagnosis in patients with Siewert type II gastroesophageal junction adenocarcinoma. Sci Rep 2023; 13:11032.

Abstract
The liver is one of the most ordinary metastatic sites of gastroesophageal junction adenocarcinoma and significantly affects its prognosis. Therefore, this study tried to construct a nomogram that can be applied to predict the likelihood of liver metastases from gastroesophageal junction adenocarcinoma. 3001 eligible patients diagnosed with gastroesophageal junction adenocarcinoma between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were involved in the analysis. Patients were randomly divided into a training cohort and an internal validation cohort using R software, with an allocation ratio of 7:3. According to the consequences of univariate and multivariate logistic regression, we constructed a nomogram for predicting the risk of liver metastases. The discrimination and calibration ability of the nomogram was appraised by the C-index, ROC curve, calibration plots, and decision curve analysis (DCA). We also used Kaplan-Meier survival curves to compare differences in overall survival in patients with gastroesophageal junction adenocarcinoma with and without liver metastases. Liver metastases developed in 281 of 3001 eligible patients. The overall survival of patients with gastroesophageal junction adenocarcinoma with liver metastases before and after propensity score matching (PSM) was obviously lower than that of patients without liver metastases. Six risk factors were finally recognized by multivariate logistic regression, and a nomogram was constructed. The C-index was 0.816 in the training cohort and 0.771 in the validation cohort, demonstrating the good predictive capacity of the nomogram. The ROC curve, calibration curve, and decision curve analysis further demonstrated the good performance of the predictive model. The nomogram can accurately predict the likelihood of liver metastases in gastroesophageal junction adenocarcinoma patients.

World J Gastroenterol 2023; 29:2433-2451. [PMID: 37179581 PMCID: PMC10167906 DOI: 10.3748/wjg.v29.i16.2433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/26/2023] [Accepted: 04/07/2023] [Indexed: 04/24/2023] Open
Abstract
Ferroptosis is an emerging novel form of non-apoptotic, regulated cell death that is heavily dependent on iron and characterized by rupture in plasma membrane. Ferroptosis is distinct from other regulated cell death modalities at the biochemical, morphological, and molecular levels. The ferroptotic signature includes high membrane density, cytoplasmic swelling, condensed mitochondrial membrane, and outer mitochondrial rupture with associated features of accumulation of reactive oxygen species and lipid peroxidation. The selenoenzyme glutathione peroxidase 4, a key regulator of ferroptosis, greatly reduces the lipid overload and protects the cell membrane against oxidative damage. Ferroptosis exerts a momentous role in regulating cancer signaling pathways and serves as a therapeutic target in cancers. Dysregulated ferroptosis orchestrates gastrointestinal (GI) cancer signaling pathways leading to GI tumors such as colonic cancer, pancreatic cancer, and hepatocellular carcinoma. Crosstalk exists between ferroptosis and other cell death modalities. While apoptosis and autophagy play a detrimental role in tumor progression, depending upon the factors associated with tumor microenvironment, ferroptosis plays a decisive role in either promoting tumor growth or suppressing it. Several transcription factors, such as TP53, activating transcription factors 3 and 4, are involved in influencing ferroptosis. Importantly, several molecular mediators of ferroptosis, such as p53, nuclear factor erythroid 2-related factor 2/heme oxygenase-1, hypoxia inducible factor 1, and sirtuins, coordinate with ferroptosis in GI cancers. In this review, we elaborated on key molecular mechanisms of ferroptosis and the signaling pathways that connect ferroptosis to GI tumors.

Abstract
BACKGROUND Similar trends in the prevalence of gastroesophageal reflux disease (GERD), obesity, and Helicobacter pylori infection have been observed in Asian and Western countries despite their time differences. However, it is unclear whether the prevalence of gastroesophageal junction adenocarcinomas in Asian countries is increasing. In this review, we discuss the epidemiological trends of gastroesophageal junction adenocarcinoma in Asian countries. SUMMARY The prevalence of GERD is increasing in Asian countries, but most cases are considered mild. Obesity is a serious problem worldwide, but it is considered less serious in Asia than in Western countries. In Asian countries where gastric cancer is common, both cardiac and noncardiac cancers are associated with high rates of H. pylori infection, which is considered a carcinogenic risk factor for both sites of cancer. The widespread use of H. pylori eradication therapy for chronic gastritis in several Asian countries has not directly led to an increased prevalence of esophageal adenocarcinoma. One of the originating sites of junctional adenocarcinoma in most Asian countries is Barrett's esophagus, with short-segment Barrett's esophagus having much lower carcinogenicity than long-segment Barrett's esophagus. Key Messages: Considering the future trends of several risk factors for gastroesophageal junction adenocarcinoma in Asian countries, it is likely that the incidence of gastroesophageal junction adenocarcinoma will gradually increase, but not at a rate that exceeds that of squamous cell carcinoma, as in Western countries.

Abstract
The aim of the present study was to investigate the expression of keratin 20 (KRT20) and placenta specific 8 (PLAC8) in gastrointestinal (GI) cancer with various differentiation phenotypes. The present study retrospectively investigated archived formalin-fixed paraffin-embedded tissue samples from 12 patients at different stages of GI cancer [four with gastric cancer, four with pancreatic cancer and four with colorectal cancer (CRC)]. The stages were pre-determined, according to differentiation phenotypes, by a pathologist of the Department of Pathology at Sijhih Cathay General Hospital. KRT20 and PLAC8 expression levels were assessed using immunohistochemistry. The CRC cell lines SW620 and Caco-2 were used to assess interactions between KRT20 and PLAC8 via reverse transcription-quantitative PCR. PLAC8 and KRT20 expression was observed consistently only in the well-differentiated CRC tissue samples. Low KRT20 expression levels were observed in the PLAC8 knockdown SW620 cells. In addition, there was a positive association between PLAC8 and KRT20 expression in the differentiated Caco-2 cells. According to the results of the present study, the differentiation status of GI cancer influenced KRT20 expression, particularly in CRC, which may explain why patients with well-differentiated CRC display better clinical outcomes. Therefore, the prognostic significance of KRT20 and PLAC8 may be particularly crucial for patients with CRC displaying a well-differentiated phenotype.

Abstract
BACKGROUND Esophageal cancer often involves direct invasion of adjacent organs and patient survival rates are low. Sarcopenia has been reported to be associated with a poor prognosis in several types of malignancies. However, the impact of sarcopenia on the long-term survival of patients with unresectable locally advanced esophageal cancer remains unclear. PATIENTS AND METHODS A total of 48 patients undergoing definitive chemoradiotherapy at our Institution from October 2012 to December 2015 were enrolled; their data were compared according to patient skeletal muscle index (SMI): low SMI (sarcopenia group), n=34; normal SMI (non-sarcopenia group), n=14. RESULTS There were no significant differences in the incidence of severe adverse events and dose reduction rate between the two groups. The incidence of nutritional support was significantly higher in the groups with sarcopenia than in the non-sarcopenia group (44.1% vs. 7.1%, p=0.077). Response rates were significantly lower in the sarcopenia group than in the non-sarcopenia group (43.8% vs. 78.6%, p=0.025). The overall survival rate in the group with sarcopenia was significantly lower than that in the non-sarcopenia group (3-year: 36.95% vs. 63.9%, p=0.018). CONCLUSION Sarcopenia prior to treatment may worsen the long-term survival of patients with unresectable locally advanced esophageal cancer. Further well-designed prospective trials are needed to estimate whether adequate nutritional support has a favorable impact on therapeutic outcomes in this population.

Abstract
Forkhead box M1 (FOXM1) and urokinase-type plasminogen activator (uPA) are overexpressed and associated with the pathogenesis of multiple types of human malignancy. The aims of the present study were to investigate FOXM1 and uPA expression levels in human gastric cancer using tissue microarray techniques; determining their association with clinicopathological characteristics as well as their prognostic value. Tissue microarray blocks, comprising 436 gastric cancer cases and 92 non-cancerous adjacent normal gastric tissues, were analyzed for FOXM1 and uPA protein expression levels using immunohistochemistry. The results were analyzed statistically in association with various clinicopathological characteristics and overall survival rates. FOXM1 and uPA were detected in 78.67 (343/436) and 83.26% (363/436) of cancer samples, respectively. FOXM1 and uPA were not expressed in the 92 normal gastric tissue samples. In gastric cancer, FOXM1 and uPA levels were associated with tumor size, depth of invasion, tumor-node-metastasis (TNM) stage, lymph node metastasis, vessel invasion and distant metastases. The overall survival rate was significantly decreased in patients expressing FOXM1 and uPA compared with FOXM1- and uPA-negative patients. Coxs multivariate analysis revealed that age, depth of invasion and expression levels of FOXM1 and uPA are independent predictors of survival in patients with gastric cancer. These results indicated that increased FOXM1 and uPA expression levels are associated with the invasive and metastatic processes in human gastric cancer, and inversely associated with patient prognosis. Therefore, FOXM1 and uPA may serve as novel prognostic markers independent of, but supplementing, the TNM staging system.

Abstract
The purpose of this study was to evaluate the prognostic impact of endoscopic traversability in patients with locally advanced esophageal squamous cell carcinoma.This retrospective study was based on medical records from a single tertiary medical center. The records of 317 patients with esophageal squamous cell carcinoma treated with surgery or definitive chemoradiotherapy (CRT) between January 2009 and March 2016 were reviewed. Finally, we retrieved the data on 168 consecutive patients. These 168 patients were divided into 2 groups based on their endoscopic traversability findings: Group A (the endoscope traversable group), and Group B (the endoscope non-traversable group). We then retrospectively compared the clinical characteristics of these 2 groups.The endoscope non-traversable group (Group B) revealed an advanced clinical stage, a poor Eastern Cooperative Oncology Group (ECOG) score, a lower serum albumin level, a higher rate of requirement for esophageal stent insertion and definitive CRT as initial treatment than the endoscope traversable group (Group A). Patients with endoscope traversable cancer showed a significantly higher 3-year overall survival and 3-year relapse-free survival than patients who were endoscope non-traversable (53.8% vs 17.3%, P < .001 and 71.1% vs 45.3%, P = .003, respectively). Upon multivariate analysis of patients with locally advanced esophageal squamous cell carcinoma treated with definitive CRT, the serum albumin level <3.5 g/dL and endoscopic non-traversability were significant negative factors of survival.Endoscopic traversability in patients with locally advanced esophageal squamous cell carcinoma treated with definitive CRT is a significant prognostic factor.

Possible Predictive Markers of Response to Therapy in Esophageal Squamous Cell Cancer. Pathol Oncol Res 2017; 25:279-288. [PMID: 29103201 DOI: 10.1007/s12253-017-0342-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 10/20/2017] [Indexed: 10/18/2022]
Abstract
The aim of the present study was to investigate the relationship between the intensity of biomarker expression and the response to radiochemotherapy in patients with advanced esophageal squamous cell cancer (ESCC). Ninety-two patients with locally advanced ESCC were examined retrospectively. Pre-treatment tumor samples were stained for proteins SOUL, Hsp 16.2, Growth Hormone-Releasing Hormone Receptor (GHRH-R) and p-Akt using immunhistochemistry methods. Kaplan-Meier curves were used to show the relationship between intensity of expression of biomarkers and clinical parameters and 3-year OS. A significant correlation was found between high intensity staining for Hsp 16.2, p-Akt and SOUL and poor response to NRCT. Application of a higher dose of radiation and higher dose of cisplatin resulted in better clinical and histopathological responses, respectively. Among the clinical parameters, the localization of the tumor in the upper-third of the esophagus and less than 10% weight loss were independent prognostic factors for increased 3-year OS. Hsp16.2, p-Akt and SOUL are predictors of negative response to NRCT, therefore these biomarkers may become promising targets for therapy. Furthermore, level of expression of p-Akt, weight loss and the localization of the tumor are significant factors in the prediction of OS in ESCC.

Abstract
OBJECTIVE To compare the diagnostic performance of MR and diffusion-weighted imaging (DWI), multidetector CT, endoscopic ultrasonography (EUS) and 18F-FDG (fluorine-18 fludeoxyglucose) positron emission tomography CT (PET-CT) in the pre-operative locoregional staging of oesophageal cancer. METHODS 18 patients with oesophageal or Siewert I tumour (9 directly treated with surgery and 9 addressed to chemo-/radiotherapy before) underwent 1.5-T MR and DWI, 64-channel multidetector CT, EUS and PET-CT before (n = 18) and also after neoadjuvant treatment (n = 9). All images were analysed and staged blindly by dedicated operators (seventh TNM edition). Two radiologists calculated independently the apparent diffusion coefficient from the first scan. Results were compared with histopathological findings. After the population had been divided according to local invasion (T1-T2 vs T3-T4) and nodal involvement (N0 vs N+), sensitivity, specificity, accuracy, positive- and negative-predictive values were calculated and compared. Quantitative measurements from DWI and PET-CT were also analysed. RESULTS For T staging, EUS showed the best sensitivity (100%), whereas MR showed the highest specificity (92%) and accuracy (83%). For N staging, MR and EUS showed the highest sensitivity (100%), but none of the techniques showed adequate results for specificity. Overall, MR showed the highest accuracy (66%) for N stage, although this was not significantly different to the other modalities. The apparent diffusion coefficient was different between surgery-only and chemo-/radiotherapy groups (1.90 vs 1.30 × 10-3 mm2 s-1, respectively; p = 0.005)-optimal cut off for local invasion: 1.33 × 10-3 mm2 s-1 (p = 0.05). Difference in standardized uptake value was also very close to conventional levels of statistical significance (8.81 vs 13.97 g cm-3, respectively; p = 0.05)-optimal cut off: 7.97 g cm-3 (p = 0.44). CONCLUSION In this pilot study, we have shown that MR with DWI could enrich the current pre-operative work-up for oesophageal cancer and could be used for T and N staging. However, larger studies will need to be carried out before introducing this technique in the standard diagnostic pathway, in order to understand if MR with DWI could change its management and replace more costly or invasive tests such as PET-CT or EUS. Advances in knowledge: This pilot study represents the first effort where the four techniques have been prospectively compared together for oesophageal cancer staging. The combination of MR and DWI could provide important, additional information for staging and initial treatment decision-making.

Melatonin downregulates nuclear receptor RZR/RORγ expression causing growth-inhibitory and anti-angiogenesis activity in human gastric cancer cells in vitro and in vivo. Oncol Lett 2016; 12:897-903. [PMID: 27446366 PMCID: PMC4950661 DOI: 10.3892/ol.2016.4729] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2015] [Accepted: 04/01/2016] [Indexed: 12/27/2022] Open
Abstract
An adequate supply of oxygen and nutrients, derived from the formation of novel blood vessels, is critical for the growth and expansion of tumor cells. It has been demonstrated that melatonin (MLT) exhibits marked in vitro and in vivo oncostatic activities. The primary purpose of the present study was to evaluate the in vitro and in vivo antitumor activity of MLT on the growth and angiogenesis of gastric cancer cells, and explore the underlying molecular mechanisms. The present results revealed that MLT inhibited the growth of gastric cancer SGC-7901 cells in a dose- and time-dependent manner. In addition, the present study demonstrated that low concentrations (0.01, 0.1 and 1 mM) of MLT had no clear effect on vascular endothelial growth factor (VEGF) secretion, whereas a high concentration (3 mM) of MLT suppressed VEGF secretion in SGC-7901 cells. Notably, administration of MLT caused suppression of gastric cancer growth and blockade of tumor angiogenesis in tumor-bearing nude mice. Furthermore, MLT treatment reduced the expression of the MLT nuclear receptor RZR/RORγ, SUMO-specific protease 1, hypoxia-inducible factor-1α and VEGF at transcriptional and translational levels within gastric cancer cells during tumorigenesis. In conclusion, MLT nuclear receptor RZR/RORγ may be of great importance in the MLT mediated anti-angiogenesis and growth-inhibitory effect in gastric cancer cells. Since RZR/RORγ is overexpressed in multiple human cancers, MLT may be a promising agent for the treatment of cancers.

Abstract
BACKGROUND Current risk scores for colorectal cancer (CRC) are based on demographic and behavioral factors and have limited predictive values. AIM To develop a novel risk prediction model for sporadic CRC using clinical and laboratory data in electronic medical records. METHODS We conducted a nested case-control study in a UK primary care database. Cases included those with a diagnostic code of CRC, aged 50-85. Each case was matched with four controls using incidence density sampling. CRC predictors were examined using univariate conditional logistic regression. Variables with p value <0.25 in the univariate analysis were further evaluated in multivariate models using backward elimination. Discrimination was assessed using receiver operating curve. Calibration was evaluated using the McFadden's R2. Net reclassification index (NRI) associated with incorporation of laboratory results was calculated. Results were internally validated. RESULTS A model similar to existing CRC prediction models which included age, sex, height, obesity, ever smoking, alcohol dependence, and previous screening colonoscopy had an AUC of 0.58 (0.57-0.59) with poor goodness of fit. A laboratory-based model including hematocrit, MCV, lymphocytes, and neutrophil-lymphocyte ratio (NLR) had an AUC of 0.76 (0.76-0.77) and a McFadden's R2 of 0.21 with a NRI of 47.6 %. A combined model including sex, hemoglobin, MCV, white blood cells, platelets, NLR, and oral hypoglycemic use had an AUC of 0.80 (0.79-0.81) with a McFadden's R2 of 0.27 and a NRI of 60.7 %. Similar results were shown in an internal validation set. CONCLUSION A laboratory-based risk model had good predictive power for sporadic CRC risk.

Abstract
Colorectal carcinomas (CRC) were initially thought to be rare in Africa including Nigeria, but recent studies have shown a reverse trend in our environment. This study is aimed to identify the clinical and pathological characteristics of CRC diagnosed between July 2006 and June 2015 in the University of Uyo Teaching Hospital, and a Private Specialist Laboratory, Uyo, Akwa Ibom State, Nigeria. All histological diagnosed cases of CRC seen in the two laboratories (University teaching and a private facility) in Uyo, Akwa-Ibom state, Nigeria during the study period were retrieved noting their bio-data, pathological and clinical variables. A total of 45 patients of age range 26-80 years with a mean of 55.9 years (SD 3.9) and a male to female ratio of 1.4:1 were seen. The two most common age groups affected in CRCs were 61-70 years (28.9%) and 51-60 years (24.4%) respectively. Majority of CRC patients were older than 40 years (86.7%) with identifiable predisposing factors being tubulo-villous adenoma (4 cases, 8.8%), villous adenoma (2 cases 4.4%), polyposis syndromes (2 cases, 4.4%) and schistosomiasis (1 case, 2.2%). Features of large intestinal obstruction were the most common presenting symptom of CRC (53.3%). Rectal bleeding, alteration in bowel habit and fecal incontinence were other symptoms, accounting for 33.3%, 8.9% and 4.4% of cases respectively. Left-sided CRCs were commoner (68.9%) with the majority appearing as annular-constricting type macroscopically (60.0%). Recto-sigmoid region was the preponderant site involved in CRC (29 cases, 64.5%). Adenocarcinoma (84.4%) was the most frequent histological subtype. Mucinous carcinoma, signet ring carcinoma and carcinoid tumor were other histologic subtypes seen in 8.9, 4.4 and 2.2% of cases respectively. The 22.0% of CRC patients presented at advanced stages of the disease. It can be concluded that majority of CRC patients were older than 40 years (86.7%) with features of intestinal obstruction (53.3%) and adenocarcinoma (84.4%) being the predominant mode of clinical presentation and histological subtype respectively.

Abstract
To our knowledge this is the first systemic review that provides an overview of the cutaneous paraneoplastic syndromes (CPS) (i.e., clinical manifestations, pathomechanisms, and treatment modalities) occurring in stomach cancer. CPS are caused by substances produced by stomach cancer and may precede, coincide with, or follow the diagnosis of this malignancy. More than 20 possible CPS in association with stomach cancer have been identified. CPS mostly compromises the patient's quality of life by skin impairment plus discomfort and are often associated with a dismal prognosis on survival. Studies of these CPS not only in stomach cancer have partially contributed to the understanding of pathomechanism and since CPS may be the presenting sign of an occult cancer, cognizance of their features and clinical implications are of considerable importance. Patients with these syndromes should have an appropriate work-up for a possibly occult malignancy with consecutive successful early treatment.

Abstract
PURPOSE To investigate the role of the apparent diffusion coefficient (ADC) as a potential prognostic biomarker in the evaluation of the aggressiveness of oesophageal cancer. MATERIALS AND METHODS Between November 2009 and December 2013, 43 patients with evidence of oesophageal or oesophago-gastric junction cancer were referred to our institution and prospectively entered in our database. The final study population consisted of 23 patients (18 men; 5 women; mean age, 64.62 ± 10.91 years) who underwent diffusion-weighted Magnetic Resonance before surgical intervention. Specifically, 14 were directly treated with surgery and 9 were addressed to chemo/radiotherapy beforehand. Two radiologists independently measured mean tumour ADC and inter-observer agreement (Spearman's and intraclass correlation coefficient [ICC]) was assessed. In the univariate analysis, overall survival curves related to pathological ADC, pT, pN, tumour location and histotype were fitted using the Kaplan-Meier method. Survival curves were then compared using the log-rank test. RESULTS Inter-observer reproducibility was very good (Spearman's rho = 0.95; ICC = 0.94). At a total median follow-up of 19 months (2-49 months), 4 patients had died. The median follow-up was 18.50 months (5-49 months) for the surgery-only group (1/4 events, 25 %) and 24 months (2-34 months) for the chemo/radiotherapy group (3/4 events, 75 %). Survival time at 48 months for the overall population was 59 % (±0.11), while for the surgery-only group and the chemo/radiotherapy group was 90 % (±0.09) and 61 % (±0.34), respectively. In the univariate analysis, ADC values below or equal to 1.4 × 10(-3) mm(2)/s were associated with a negative prognosis both in the total population (P = 0.016) and in the surgery-only group (P < 0.001). CONCLUSION Despite the biggest limitation of our study (i.e. the small study population), we were able to show that pathological ADC could be considered a prognostic factor for oesophageal cancer. DWI might be introduced into clinical practice as a promising and reliable technique in the diagnostic pathway of this tumour.

Monitoring tumour response during chemo-radiotherapy: a parametric method using FDG-PET/CT images in patients with oesophageal cancer. EJNMMI Res 2014; 4:12. [PMID: 24602385 PMCID: PMC3973855 DOI: 10.1186/2191-219x-4-12] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2013] [Accepted: 02/18/2014] [Indexed: 01/28/2023] Open
Abstract
Background The objective of this study is to investigate the feasibility and the additional interest of a parametric imaging (PI) method to monitor the early tumour metabolic response in a prospective series of oesophageal cancer patients who underwent positron emission tomography with fluoro-2-deoxy-d-glucose (FDG-PET/CT) before and during curative-intent chemo-radiotherapy. Methods Fifty-seven patients with squamous cell carcinoma (SCC) of the oesophagus prospectively underwent FDG-PET/CT before chemo-radiotherapy (CRT) (PET1) and at 21 ± 3 days after the beginning of CRT (PET2). The outcome was assessed at 3 months and 1 year after the completion of CRT (clinical examination, CT scan or FDG-PET/CT, biopsy). For each patient, PET1 and PET2 were registered using CT images. The 2 PET image sets were subtracted, so the voxels with significant changes in FDG uptake were identified. A model-based analysis of this graph was used to identify the tumour voxels in which significant changes occurred between the two scans and yielded indices characterising these changes (green and red clusters). Quantitative parameters were compared with clinical outcome at 3 months and at 1 year. Results The baseline tumour FDG uptake decreased significantly at PET2 (p < 0.0001). The tumour volume significantly decreased between PET1 and PET2 (p < 0.02). The initial functional volume of the lesion (TV1) was significantly lower (p < 0.02) in patients in clinical response (CR) at 3 months and 1 year. The volume of the lesion during the treatment (TV2) was significantly lower in patients identified as in CR at 3 months (p < 0.03), but did not predict the outcome at 1 year. Multivariate analyses of outcome at 3 months showed that the risk of failure/death increased with younger age (p = 0.001), larger metabolic volume on PET1 (p = 0.009) and larger volume with decreased FDG uptake (p = 0.047). As for outcome at 1 year, the risk of failure/death increased with younger age (p = 0.006), nodal involvement (p = 0.08) and larger volumes with increased uptake (p = 0.03). Conclusion A parametric method to assess tumour response on serial FDG-PET performed during chemo-radiotherapy was evaluated. Early metabolic changes, i.e. variations in FDG uptake, provided additional prognostic information in multivariate analyses ClinicalTrials.gov NCT 00934505.

Abstract
BACKGROUND Undernutrition is frequently observed in patients with a locally advanced oesophageal carcinoma. However, variations of nutritional parameters during chemoradiotherapy have not been thoroughly investigated. AIM To evaluate the characteristics and the impact of nutritional variations during treatment. METHODS Weight loss, body mass index (BMI), serum albumin level and daily food intake at baseline and during treatment (T1=week 1; T2=week 5 or 8; T3=week 11) were retrospectively analyzed in 101 patients with oesophageal carcinoma. RESULTS Significant variations occurred during chemoradiotherapy with a decrease in serum albumin level (p<0.001), body mass index (p<0.001) and weight (p<0.001). Response rate to treatment was significantly lower in patients with undernutrition at T1 (p=0.05), from T1 to T2 (p=0.01) and from T1 to T3 (p=0.04). Median overall survival was 25 months in patients with persistent undernutrition from T1 to T2 vs 42 months in wellnourished patients from T1 to T2 and those malnourished only at T1 or T2 (p=0.05). In responders, patients presenting with a lower weight or a lower food intake from T1 to T3 had worse survival (33 vs 59 months, p<0.001 and 29 vs 61 months, p=0.001, respectively). CONCLUSION Significant variations of nutritional parameters occurred during chemoradiotherapy with a worse impact on response and survival.

Abstract
BACKGROUND. CARD15 is involved in the innate immune response and mutations of this gene have been linked with increased risk of Crohn's disease and colorectal cancer. The relation between CARD15 mutations and gastric cancer (GC) remains controversial. AIMS. To assess whether CARD15 mutations are risk factors for GC in Portugal and whether there are genotype-phenotype correlations in these patients. METHODS. The 3 main CARD15 mutations (3020insC, R702W and G908R) were searched in 150 patients with GC and in 202 healthy controls. RESULTS. Overall, CARD15 mutations were found in 28 patients (18.7%) and in 27 controls (13.4%) (p = 0.176). Individually, the incidence of 3020insC was significantly higher in patients than in controls (6.0% vs. 1.0%, p = 0.021). This polymorphism was linked with an increased risk for the intestinal-type of GC (p = 0.002), while no association was found with the diffuse and/or mixed types. Genotype frequencies for R702W (10.0% vs. 7.9%) and G908R (4.0% vs. 4.0%) were not statistically different between the two groups. Similarly, no significant associations were detected between these two polymorphisms and the different histological GC types. No correlations were observed between CARD15 mutations and family history, mean age at diagnosis or GC stage. CONCLUSIONS. The CARD15 3020insC variant is a risk factor for intestinal GC in Portugal. CARD15 variants are not correlated with age of diagnosis or family aggregation of the disease neither with the GC stage.

Abstract
The role of hypoxia-inducible factors-1 alpha (HIF-1α) expression in gastric cancer remains controversial. We performed a systematic review of the literature with meta-analysis. Electronic databases were used to identify published studies before December 1, 2012. Pooled hazard ratio (HR) or odds ratio (OR) with 95 % confidence interval (95 % CI) was used to estimate the strength of the association between HIF-1α expression and survival of gastric cancer patients. Heterogeneity and publication bias were also assessed. Final analysis of 1,268 patients from 9 eligible studies was performed. High HIF-1α expression was significantly correlated with poor overall survival (OS) of gastric cancer patients (HR = 2.14, 95 % CI = 1.32-3.48). Subgroup analysis indicated that HIF-1α over-expression had an unfavorable impact on OS in Asian patients (HR = 2.35, 95 % CI = 1.41-3.92). Moreover, up-regulation of HIF-1α was significantly associated with the depth of invasion (OR = 2.49, 95 % CI = 1.28-4.83), lymph node metastasis (OR = 2.15, 95 % CI = 1.27-3.66), and vascular invasion (OR = 2.23, 95 % CI = 1.20-4.14). HIF-1α expression might be a predicative factor of poor prognosis for gastric cancer particularly in Asia.

Abstract
AIM: To identify the role of human development in the incidence and mortality rates of gastrointestinal cancers worldwide.
METHODS: The age-standardized incidence and mortality rates for gastrointestinal cancers, including cancers of the esophagus, stomach, pancreas, liver, gallbladder, and colorectum, were obtained from the GLOBOCAN 2008 database and United States Cancer Statistics (USCS) report. The human development index (HDI) data were calculated according to the 2011 Human Development Report. We estimated the mortality-to-incidence ratios (MIRs) at the regional and national levels, and explored the association of the MIR with development levels as measured by the HDI using a modified “drug dose to inhibition response” model. Furthermore, countries were divided into four groups according to the HDI distribution, and the MIRs of the four HDI groups were compared by one-way ANOVA followed by the Tukey-Kramer post-hoc test. State-specific MIRs in the United States were predicted from the estimated HDI using the fitted non-linear model, and were compared with the actual MIRs calculated from data in the USCS report.
RESULTS: The worldwide incidence and mortality rates of gastrointestinal cancers were as high as 39.4 and 54.9 cases per 100000 individuals, respectively. Linear and non-linear regression analyses revealed an inverse correlation between the MIR of gastrointestinal cancers and the HDI at the regional and national levels (β < 0; P = 0.0028 for regional level and < 0.0001 for national level, ANOVA). The MIR differed significantly among the four HDI areas (very high HDI, 0.620 ± 0.033; high HDI, 0.807 ± 0.018; medium HDI, 0.857 ± 0.021; low HDI, 0.953 ± 0.011; P < 0.001, one-way ANOVA). Prediction of the MIRs for individual United States states using best-fitted non-linear models showed little deviation from the actual MIRs in the United States. Except for 28 data points (9.93% of 282), the actual MIRs of all gastrointestinal cancers were mostly located in the prediction intervals via the best-fit non-linear regression models.
CONCLUSION: The inverse correlation between HDI and MIR demonstrates that more developed areas have a relatively efficacious healthcare system, resulting in low MIRs, and HDI can be used to estimate the MIR.

Abstract
PURPOSE FDG PET has been suggested to have predictive value in the prognosis of oesophageal carcinoma. However, the retrospective studies reported in the literature have shown discordant results. Additionally, only four studies have evaluated FDG PET during chemoradiotherapy (CRT) in patients with different histological lesions. The purpose of this study was to investigate the predictive value of FDG PET performed early during CRT (on day 21) in a population of patients with oesophageal squamous cell carcinoma. METHODS Included in this prospective study were 57 patients with a histological diagnosis of squamous cell carcinoma of the oesophagus. Of these 57 patients, 48 (84%) were evaluated (aged 63 ± 11 years; 44 men, 4 women). Each patient underwent FDG PET (4.5 MBq/kg) before CRT, according to the Herskovic protocol (t0; PET₁) and on day 21 ± 3 from the start of CRT (d21; PET₂). The response assessment included a clinical examination, CT scan or FDG PET and histological analysis 3 months and 1 year after PET₁. The patients were classified as showing a complete response (CR) or a noncomplete response. A quantitative analysis was carried out for PET₁ and PET₂ using the following parameters: SUVmax, SUVmean (with SUVmean40 as the 3-D volume at an SUVmax threshold of 40% and SUVmeanp as that defined by a physician), tumour volume (TV, with TV40 defined as the TV at 40% of SUVmax, and TVp as that defined by a physician); and the total lesion glycolysis (TLG, SUVmean × TV, with TLG₄₀ defined as the TLG at 40% of SUVmax, and TLGp as that defined by a physician). The differences in responses at 3 months and 1 year between PET₁ (t0) and PET₂ (d21) were assessed in terms of variations in SUV, TV and TLG using a repeated measures of variance (ANOVA). RESULTS SUVmax, SUVmean and TLG decreased significantly between PET₁ (t0) and PET₂ (d21; p < 0.0001). The TV significantly decreased only when assessed as TVp (p = 0.02); TV₄₀ did not decrease significantly. With respect to the predictive value of PET₁, only TV40_1 and TVp_1 values, and therefore TLG40_1 and TLGp_1, but not the SUV values, were significantly lower in patients with CR at 3 months. SUVmax1, TVp_1 and TLGp_1 were significantly lower in patients with CR at 1 year. With respect to the predictive value of PET₂, only TV40_2 and TVp_2 values, and therefore TLG40_2 and TLGp_2, but not the SUV values, were significantly lower in patients with CR at 3 months. None of the PET₂ parameters had significant value in predicting patient outcome at 1 year. The changes in SUVmax, TV₄₀, TVp, TLG₄₀ and TLGp between PET₁ and PET₂ had no relationship to patient outcome at 3 months or 1 year. CONCLUSION This prospective, multicentre study performed in a selected population of patients with oesophageal squamous cell cancer demonstrates that the parameters derived from baseline PET₁ are good predictors of response to CRT. Specifically, a high TV and TLG are associated with a poor response to CRT at 3 months and 1 year, and a high SUVmax is associated with a poor response to CRT at 1 year. FDG PET performed during CRT on day 21 appears to have less clinical relevance. However, patients with a large functional TV on day 21 of CRT have a poor clinical outcome (ClinicalTrials.gov NCT 00934505).

Abstract
Elderly patients are at increased risk for peptic ulcer and cancer. Predictive factors of relevant endoscopic findings at upper endoscopy in the elderly are unknown. This was a post hoc analysis of a nationwide, endoscopic study. A total of 3,147 elderly patients were selected. Demographic, clinical, and endoscopic data were systematically collected. Relevant findings and new diagnoses of peptic ulcer and malignancy were computed. Both univariate and multivariate analyses were performed. A total of 1,559 (49.5%), 213 (6.8%), 93 (3%) relevant findings, peptic ulcers, and malignancies were detected. Peptic ulcers and malignancies were more frequent in >85-year-old patients (OR 3.1, 95% CI = 2.0-4.7, p = 0.001). The presence of dysphagia (OR = 5.15), weight loss (OR = 4.77), persistent vomiting (OR = 3.68), anaemia (OR = 1.83), and male gender (OR = 1.9) were significantly associated with a malignancy, whilst overt bleeding (OR = 6.66), NSAIDs use (OR = 2.23), and epigastric pain (OR = 1.90) were associated with the presence of peptic ulcer. Peptic ulcer or malignancies were detected in 10% of elderly patients, supporting the use of endoscopy in this age group. Very elderly patients appear to be at higher risk of such lesions.

Abstract
Adenosine monophosphate-activated protein kinase (AMPK) is a principal intracellular energy sensor which regulates energy producing pathways and energy requiring pathways when the cellular AMP/ATP ratio is altered. BML-275 (compound C), a well-known inhibitor of AMPK, has been found to induce apoptosis in myeloma, glioma and prostate cancer cells. However, the mechanisms responsible for the selective apoptotic effect(s) by BML-275 in cancer cells remain unknown. In the present study, BML-275 was investigated for its antitumor effect(s) in human pancreatic cancer cell lines. BML-275 inhibited the cell proliferation of 4 human pancreatic cancer cell lines (MIA PaCa-2, Panc-1, Colo-357 and AsPC-1). In addition, BML-275 significantly increased the generation of intracellular reactive oxygen species (ROS), followed by induction of DNA damage signaling and apoptosis. Furthermore, BML-275 induced cell cycle arrest in the G2/M phase. The inhibition of ROS generation by N-acetyl cysteine (NAC) significantly prevented the induction of DNA damage and apoptosis, but failed to prevent the induction of G2/M arrest by BML-275. Small interfering RNA (siRNA)-mediated knockdown of AMPKα increased the generation of intracellular ROS, DNA damage signaling and apoptosis without cell cycle arrest at the G2/M phase. These findings suggest that BML-275 exerts its antitumor effects by inducing ROS generation, DNA damage and apoptosis via inhibition of the AMPK pathway and by inducing G2/M arrest via a pathway independent of AMPK, implicating its potential application as an antitumor agent for pancreatic cancer.

Abstract
INTRODUCTION Cervical oesophagus represents a critical location for squamous cell carcinoma, which usually requires extensive surgery (pharyngo-laryngo-oesophagectomy). In the last decade, neoadjuvant chemo-radiotherapy was reported to be beneficial in the treatment of locally advanced squamous cell oesophageal cancer. METHODS Between November 1997 and January 2012, 55 patients with locally advanced (T3-4) squamous cell oesophageal cancer received preoperative chemo-radiotherapy, where the tumour was localized in the upper third. Patients received preoperative irradiation of 3960 cGy in 180 cGy fractions and simultaneously Cisplatin and 5-FU chemotherapy. Restaging was carried out after four weeks and patients considered operable were underwent surgery. RESULTS In patients with cervical oesophageal cancer 35 of 55 (64%) underwent oesophageal resection or pharyngo-laryngectomy. In 16 out of 35 resected specimens (46%) complete histopathological remission (pCR) was observed. Perioperative mortality and anastomotic leaks were the same: 5/35 (14%). R0 resection rate was 82% and the 2- and 5 years survival rates were 41% and 18%. In 19 cases a larynx preserving pharyngo-oesophagectomy was performed and a free jejunal graft was used for reconstruction after a pharyngo-laryngectomy in 11 cases. CONCLUSION The high rate of pCR (46%) confirmed that upper third oesophageal cancer has superior sensitivity to multimodal treatment. In 30 cases neoadjuvant chemo-radiotherapy was able to achieve tumour regression and render pharyngo-laryngo-oesophagectomy unnecessary.

Abstract
The current S3 guidelines on the diagnosis and treatment of gastric carcinoma including those of the esophagogastric junction describe optimal clinical practice based on a high level of evidence and expert consensus from different medical disciplines. Endoscopy and performance of multiple biopsies is the standard approach to detect malignant tumors in the upper gastrointestinal tract. Further diagnostic procedures are necessary to evaluate the tumor stage. With the exception of mucosal carcinomas, surgical therapy is the cornerstone of curative treatment in all potentially resectable stages. In locally advanced carcinomas perioperative chemotherapy should be carried out and in high-seated tumors preoperative radiochemotherapy might be an alternative option. Palliative surgical resection should be avoided in disseminated asymptomatic stages. In a palliative situation complications of the tumor should primarily be treated by interventional or conservative procedures.

Abstract
BACKGROUND Gastric cancer has become less common but remains among the leading causes of death from cancer, with a 5-year survival rate of only 20% to 25%. Although diagnostic techniques have improved, most patients with gastric cancer in the Western world (unlike in some Asian countries) already have locally advanced disease when diagnosed and may thus need not only surgery, but also perioperative chemotherapy and/or radiotherapy. METHOD Articles published from 2000 to 2010 and containing the terms "gastric cancer," "surgery," and "chemotherapy" in combination with "review" or "randomized trial" were retrieved by a search in the Cochrane Library and Medline databases and selectively reviewed. RESULTS Complete (R0) resection of the tumor remains the standard treatment whenever possible. Complete endoscopic resection suffices only in special types of carcinoma that are confined to the gastric mucosa. Depending on the histological findings, either a subtotal distal gastrectomy or a total (perhaps extended total) gastrectomy can be performed. The long-term benefit of systematic D2 lymphadenectomy has now been shown in a randomized trial: the rates of tumor-related death and of local or regional recurrence were found to be significantly lower with D2 than with D1 lymphadenectomy. Multimodal treatment strategies including perioperative chemotherapy and/or radiotherapy can further improve local and regional tumor control and lessen the rate of systemic metastasis. CONCLUSION The standardization of surgical procedures lowered the operative risk in the treatment of gastric cancer. Patients with locally advanced disease can now derive additional benefit from perioperative chemotherapy with an increase of the 5-year survival rates of more than 10%.

Abstract
The phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway is important in cell proliferation and survival, and it is frequently and aberrantly activated in pancreatic adenocarcinoma. Potential anti-tumor effect(s) of ZSTK474, a PI3K/Akt inhibitor, together with a key clinically relevant anti-tumor agent, gemcitabine (GEM), have been reported in a human pancreatic cancer xenograft mouse model. However, the precise molecular mechanism of these anti-tumor effects has not been well elucidated. In this study, we investigated the molecular mechanism of GEM plus ZSTK474 in reducing tumor cell survival in human pancreatic cancer cell lines. Our study showed that ZSTK474 inhibited cell growth by arresting cells at the G1 phase and by inducing apoptosis. ZSTK474 also inhibited the phosphorylation of Akt, GSK3β and BAD. The combination of GEM and ZSTK474 demonstrated synergistic anti-tumor effects on pancreatic cancer cells in both transient (3 days) and long-term (14 days) clonogenic assays. Thus, we elucidated the potential molecular mechanism leading to the enhanced anti-tumor effect when GEM and ZSTK474 are combined in treatment.

Abstract
The quality of colon cleansing and the tolerance of patients to the procedure are two major determinants of the quality of a colonoscopy. Many bowel-cleansing regimens are known, but there is no ideal regimen. Alverine citrate (Relaxyl, Spasmonal) is a spasmolytic agent that has been shown to affect responses of mechanoreceptors of the intestine to both mechanical and chemical stimuli. Patients who underwent colonoscopies at four centers were randomly assigned two different bowel-cleansing procedures. The bowel-cleansing methods were oral sodium phosphate (NaP) (Group I) and oral NaP plus alverine citrate (Group II). Patients were randomized into one of these regimens. The quality of colon cleansing was assessed by an endoscopist with an empirical, clinically meaningful 3-point scale. Both groups were similar with respect to age, gender, and pre- and postcolonoscopic diagnosis. In Group I, 76 patients (47 women and 29 men; aged 39.53 ± 7.87 years) and in Group II, 71 patients (41 women and 30 men; aged 39.78 ± 8.27 years) were included in the study. In Groups I and II, 37 (48.7%) and 41 (57.7%) patients had perfect bowel cleansing, respectively. The overall colon cleansing in the group with NaP plus alverine citrate was comparable with that in the NaP group. The tolerability of patients to the colonoscopy in the two groups was also similar. Based on the present data, adding oral alverine citrate to NaP does not increase either the quality of bowel cleansing or the tolerance of patients to the procedure.

Abstract
Evaluation of the feasibility and efficacy of neoadjuvant concurrent chemoradiotherapy (CRT) with capecitabine and oxaliplatin in patients with locally advanced esophageal cancer. Forty-two patients were eligible for the study. The chemotherapy during CRT consisted of two cycles of intravenous oxaliplatin of 120 mg/m(2) on day 1 and oral capecitabine 825 mg/m(2) twice daily on days 1-14 at 3-week intervals. The radiotherapy (1.8 Gy/fraction/day to a total dose of 45 Gy) was delivered to the primary tumor site and regional lymph node. All patients completed the planned treatment. Overall clinical response rate was 54.8% with complete response in 16.7% while pathological response rate was 38%. Anemia was the commonest hematologic toxicity (52.3%) with grade 3 in 4.7%, and esophagitis was the commonest non-hematologic toxicity 59.5% with grade 3 and 4 in 9.5%. No treatment-related death was observed. After a median follow-up duration of 19 months, the 2-year survival rate was 42%, median survival time was 20 months (95%CI: 13.802-26.198), while 2-year progression-free survival (PFS) rate was 32.5% with median PFS time of 15 months (95%CI: 10.042-19.958). Neoadjuvant concurrent CRT with capecitabine and oxaliplatin was found to be well tolerated and effective in patients with locally advanced esophageal cancer; however, these results should be further evaluated in a phase III study.

Abstract
AIMS Tumour budding and host inflammatory response are parameters easily assessed histologically that have prognostic significance in many cancers. There have been few studies examining these parameters in oesophageal or gastro-oesophageal cancers. This study aims to address that deficiency. METHODS AND RESULTS A two-centre, retrospective study was carried out on 356 patients. Tumour budding and host inflammatory response at the invasive front were assessed histologically. Statistical analysis was performed to determine the prognostic significance of these factors. The median number of tumour buds was four (range 0-50) with 172 of 356 cases having five or more buds at the invasive front. The presence of five or more buds was associated with a poor prognosis on univariate analysis (P = 0.0001), as was a sparse or moderate host inflammatory response (P = 0.001). Tumour budding retained prognostic significance when tumours were separated into adenocarcinomas (n = 287) and squamous cell carcinomas (n = 69), but host inflammatory response was a significant prognostic factor only for adenocarcinomas. On multivariate analysis the presence of five or more buds retained significance (P = 0.002). CONCLUSIONS Tumour budding and host inflammatory response are important prognostic factors in patients with oesophageal/gastro-oesophageal cancer and can be used to identify high-risk patients who would benefit from closer follow-up and adjuvant therapies.

Abstract
BACKGROUND The European Community has made a commitment to colorectal cancer (CRC) screening, but regional considerations may affect the design of national screening programs. We developed a decision analytic model tailored to a pilot screening program for high-risk persons in Spain with the aim of informing public policy decisions. MATERIALS AND METHODS We constructed a decision analytic Markov model based on our validated model of CRC screening that reflected CRC epidemiology and costs in persons with first-degree relatives with CRC in Aragón, Spain, and superimposed colonoscopy every 5 or 10 years from ages 40 to 80 years. The pilot program's preliminary clinical results and our modeling results were presented to regional health authorities. RESULTS In the model, without screening, 88 CRC cases occurred per 1,000 persons from age 40 to 85 years. In the base case, screening reduced this by 72% to 77% and gained 0.12 discounted life years per person. Screening every 10 years was cost saving, and screening every 5 years versus every 10 years cost 7,250 euros per life year gained. Based on these savings, 36 to 39 euros per person per year could go toward operating costs while maintaining a neutral budget. If screening costs doubled, screening remained highly cost-effective but no longer cost saving. These results contributed to the health authorities' decision to expand the pilot program to the entire region in 2009. CONCLUSIONS Colonoscopic screening of first-degree relatives of persons with CRC may be cost saving in public systems like that of Spain. Decision analytic modeling tailored to regional considerations can inform public policy decisions. IMPACT Tailored decision analytic modeling can inform regional policy decisions on cancer screening.

Abstract
BACKGROUND Immunochemical tests show important advantages over chemical-based faecal occult blood tests (FOBT) for colorectal cancer (CRC) screening, but comparison studies are limited. This study was performed to compare the accuracy of a sensitive immunochemical test with the guaiac test for detecting significant neoplasia (advanced adenomas and CRC) in an average-risk population. METHODS A random sample of 2288 asymptomatic subjects 50-79 years of age was prospectively included. Participants received three cards of the guaiac test, one sample of a latex-agglutination test (haemoglobin cut-off 50 ng/ml), and an invitation to undergo colonoscopy. Test sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated in 1756 compliers. RESULTS Immunochemical and guaiac tests were positive in 143 (8.1%) and 62 (3.5%) subjects, respectively. Complete colonoscopy, performed in 402 participants (158 FOBT+ and 244 FOBT-), detected 14 (0.8%) patients with CRC and 49 (2.8%) with advanced adenomas. The immunochemical and guaiac tests for significant colorectal neoplasia showed sensitivities of 61% versus 23.8%, specificities of 95.1% versus 97.7%, PPVs of 43.4% versus 39.0%, and NPVs of 97.5% versus 95.4%, respectively. Proximal significant neoplasms were more frequently detected with the immunochemical test (85% vs. 15%) The relative risk for detecting significant neoplasia was superior in patients with a positive immunochemical test (RR 16.93; CI 7.94-36.10) than with a positive guaiac test (RR 3.34; CI 2.17-5.15). CONCLUSION A sensitive immunochemical test is markedly superior to the guaiac test for detecting significant colorectal neoplasia, and should be considered the first-choice FOBT for CRC screening in the average-risk population.

Abstract
BACKGROUND Low public awareness is an important barrier for colorectal cancer screening participation. AIM To evaluate the impact of educational intervention on the health behavior process, patient knowledge and compliance with colorectal cancer screening in the average-risk population. METHODS 158 subjects (aged 50-79 years) were randomly assigned either to watch a non-medical video or a colorectal cancer educational video. Before and after watching the experimental or control videotape, participants completed a five-item questionnaire that assessed their knowledge about risk factors for colorectal cancer, age of risk, warning symptoms, 5-year prognosis, and incidence. Subjective risk perception for developing colorectal cancer, barriers or benefits of screening, and intention to be screened were also investigated. Finally, subjects received a faecal occult blood test kit and were requested to use and return it within 2 weeks. RESULTS Participants in the video-based intervention group showed significant improvement in knowledge of colorectal cancer scores (P<0.001) and decreased barrier scores. The intervention group returned significantly more faecal occult blood tests than controls (69.6% vs. 54.4%, P=0.035). The intervention had a positive effect on modifying attitudes and intention to take part in screening. Additionally, the intervention was a predictor of compliance (OR 2.0; 95% CI=1.02-3.84, P=0.044). CONCLUSION Video-based intervention significantly reduced barriers to screening and improved participant awareness and compliance with colorectal cancer screening with faecal occult blood test.

Abstract
Background: A major obstacle to the successful management of pancreatic cancer is to acquire resistance to the existing chemotherapeutic agents. Resistance to gemcitabine, the standard first-line chemotherapeutic agent for advanced and metastatic pancreatic cancer, is mainly attributed to an altered apoptotic threshold in the pancreatic cancer. The MUC4 transmembrane glycoprotein is aberrantly overexpressed in the pancreatic cancer and recently, has been shown to increase pancreatic tumour cell growth by the inhibition of apoptosis. Methods: Effect of MUC4 on pancreatic cancer cells resistance to gemcitabine was studied in MUC4-expressing and MUC4-knocked down pancreatic cancer cell lines after treatment with gemcitabine by Annexin-V staining, DNA fragmentation assay, assessment of mitochondrial cytochrome c release, immunoblotting and co-immunoprecipitation techniques. Results: Annexin-V staining and DNA fragmentation experiment demonstrated that MUC4 protects CD18/HPAF pancreatic cancer cells from gemcitabine-induced apoptosis. In concert with these results, MUC4 also attenuated mitochondrial cytochrome c release and the activation of caspase-9. Further, our results showed that MUC4 exerts anti-apoptotic function through HER2/extracellular signal-regulated kinase-dependent phosphorylation and inactivation of the pro-apoptotic protein Bad. Conclusion: Our results elucidate the function of MUC4 in imparting resistance to pancreatic cancer cells against gemcitabine through the activation of anti-apoptotic pathways and, thereby, promoting cell survival.

Abstract
PURPOSE This study aimed to develop an efficient and safe strategy to introduce suicide genes into colon cancer cells. EXPERIMENTAL DESIGN In this study, we fused an enhanced carcinoembryonic antigen promoter (CEA) to a suicide gene, cytosine deaminase (CD). This construct was delivered into colon cancer cells using calcium phosphate nanoparticles (CPNP). The cells were then treated with the prodrug 5-FC. The therapeutic effect was evaluated in vitro and in vivo. RESULTS Our study showed that the CEA promoter-driven, CPNP-delivered suicide gene was only expressed in CEA-positive colon cancer cells, and resulted in significant cytotoxicity after administration of the prodrug 5-FC in vitro. Moreover, our in vivo study showed that CPNP-mediated CEA-CD delivery, together with 5-FC treatment, resulted in significant tumor growth delay in xenograft human colon carcinoma. CONCLUSIONS Our study indicates that the combination of CPNP and CEA-CD gene expression represents a novel approach for CEA-positive tumor gene therapy.

Abstract
OBJECTIVES To investigate the anticancer effect and potential mechanism of combination treatment with arsenic trioxide (ATO) and parthenolide (PTL) in human pancreatic cancer cells. METHODS The effects of PTL/ATO on 2 pancreatic carcinoma cell lines, PANC-1 and BxPC-3, were determined by trypan blue exclusion, annexin V/propidium iodide, 4',6-diamidino-2-phenylindole HCl, terminal deoxynucleotidyltransferase-mediated nick-end labeling, flow cytometry, Western blot, and clonogenic assay. In vivo study was performed in PANC-1 tumor xenografts in nude mice. RESULTS The combination of PTL and ATO inhibited the growth of pancreatic tumor cell lines much greater than each agent alone. The PTL/ATO treatment induced apoptosis and reactive oxygen species generation. Both of them were inhibited by L-N-acetylcysteine and diphenylene iodonium chloride. During ATO/PTL-mediated apoptosis, the collapse of mitochondrial transmembrane potential occurred with cytochrome c release, which was reversed by L-N-acetylcysteine. The combination treatment significantly reduced tumor growth rates of PANC-1 xenografts compared with those treated with either PTL or ATO alone. CONCLUSIONS Combination therapy with ATO and PTL has an augmented anticancer effect on pancreatic cancer in vitro and in vivo, which provides a novel promising approach in the treatment of pancreatic cancer. The mechanism of growth-suppressive effect of combination therapy was correlated with its ability to induce reactive oxygen species generation and apoptosis via the mitochondrial pathway.

Abstract
Survivin is known to be overexpressed in various human malignancies, including pancreatic cancer, and to cause resistance to radiation and chemotherapy, so the regulation of this molecule could be a new strategy for treating pancreatic cancer. In our study, a short interfering RNA (siRNA) plasmid expression vector against survivin was constructed and transfected into human pancreatic cancer cell lines of Panc-1 and BxPC3. The expression of survivin mRNA and protein among the stable transfected cells and the untransfected cells was detected by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot, respectively. Tumor cell growth in vitro was assessed by trypan blue exclusion. The cell cycle distribution and cell apoptosis were measured by flow cytometry. The cytotoxicity assay was measured by the MTT test. Our results showed that survivin siRNA treatment caused a specific and profound decrease of survivin mRNA and protein that was associated with decreased cell growth, spontaneous apoptosis, and a specific G0/G1 arrest. Furthermore, the suppression of survivin can enhance the chemosensitivity of pancreatic cancer cells to gemcitabine significantly. We suggest that the RNAi against survivin gene strategy would be a potential approach to chemosensitization therapy in human pancreatic cancer.

Abstract
OBJECTIVE The incidence rates of oesophageal cancer vary more than those of any other cancer, world-wide. The aim of this study was to examine the epidemiological features of oesophageal cancer in the Nordic countries. MATERIAL AND METHODS Epidemiological data from the Nordic Cancer Registry (NORDCAN Database, http://www.ancr.nu/nordcan.asp) were used for the study analysis. RESULTS From 1971 to 2000 in the Nordic countries, 18,034 oesophageal cancers were detected in males and 8216 in females. In males, the incidence rates (world age standardized incidence per 100,000) of oesophageal cancer in 1971-75 and 1996-2000 were 2.7 and 6.0 in Denmark, 4.2 and 3.2 in Finland, 3.4 and 5.6 in Iceland, 2.6 and 3.3 in Norway, and 2.9 and 3.3 in Sweden, respectively. In females, the corresponding figures were: Denmark 1.1 and 1.8, Finland 3.1 and 1.3, Iceland 2.5 and 1.3, Norway 0.7 and 0.9, and Sweden 1.1 and 1.0. Each Nordic country showed a significant geographical variation in the incidence of oesophageal cancer. In both males and females the incidence curves began rising after 40 years of age, but significantly more steeply in males than in females. Over the study period, oesophageal cancer mortality increased from 2.97 to 3.68 per 100,000 in males but decreased from 1.30 to 1.08 in females. The incidence rates of oesophageal adenocarcinoma increased in males in all Nordic countries, and the increase was most marked in Denmark. The incidence of oesophageal adenocarcinoma also increased among Danish females, but compared with males, the incidence rate remained significantly lower. CONCLUSIONS The time trends in incidence of oesophageal cancer differ between the Nordic countries, and there has also been geographical variation within them. On a global comparison, the incidence rates of oesophageal cancer are low in the Nordic region. Oesophageal cancer is a male-predominant disease in all Nordic countries, and the incidence rates of oesophageal adenocarcinoma have increased in males and Danish females.

Abstract
Over the past 30 years, the population of old-aged citizens in most Western countries has been dramatically increasing. These people usually have several comorbidities and often lose their independence, mostly due to neurodegenerating diseases. Benign and malignant gastrointestinal disorders are very common in all age groups, but their incidence increases with age, requiring investigation and therapy. In this setting several ethical issues arise, mostly related to the extent of invasive investigations, adverse drug reactions due to polypharmacy, the risk:benefit ratio of endoscopic therapy, and the quality and validity of informed consent in this frail elderly population.
