Abstract
Pancreatic cancer (PC) ranks as the seventh leading cause of cancer-related deaths, with approximately 500,000 new cases reported in 2020. Existing strategies for early PC detection primarily target individuals at high risk of developing the disease. Nevertheless, there is a pressing need to identify innovative clinical approaches and personalized treatments for effective PC management. This study aimed to explore the dysbiosis signature of the fecal microbiota in PC and potential distinctions between its Intraductal papillary mucinous neoplasm (IPMN) and pancreatic ductal adenocarcinoma (PDAC) phenotypes, which could carry diagnostic significance. The study enrolled 33 participants, including 22 diagnosed with PDAC, 11 with IPMN, and 24 healthy controls. Fecal samples were collected and subjected to microbial diversity analysis across various taxonomic levels. The findings revealed elevated abundances of Firmicutes and Proteobacteria in PC patients, whereas healthy controls exhibited higher proportions of Bacteroidota. Both LEfSe and Random Forest analyses indicated the microbiome's potential to effectively distinguish between PC and healthy control samples but fell short of differentiating between IPMN and PDAC samples. These results contribute to the current understanding of this challenging cancer type and highlight the applications of microbiome research. In essence, the study provides clear evidence of the gut microbiome's capability to serve as a biomarker for PC detection, emphasizing the steps required for further differentiation among its diverse phenotypes.

Abstract
PURPOSE Emergency laparotomy (EL) is a common operation with high risk for postoperative complications, thereby requiring accurate risk stratification to manage vulnerable patients optimally. We developed and internally validated a predictive model of serious complications after EL. METHODS Data for eleven carefully selected candidate predictors of 30-day postoperative complications (Clavien-Dindo grade > = 3) were extracted from the HELAS cohort of EL patients in 11 centres in Greece and Cyprus. Logistic regression with Least Absolute Shrinkage and Selection Operator (LASSO) was applied for model development. Discrimination and calibration measures were estimated and clinical utility was explored with decision curve analysis (DCA). Reproducibility and heterogeneity were examined with Bootstrap-based internal validation and Internal-External Cross-Validation. The American College of Surgeons National Surgical Quality Improvement Program's (ACS-NSQIP) model was applied to the same cohort to establish a benchmark for the new model. RESULTS From data on 633 eligible patients (175 complication events), the SErious complications After Laparotomy (SEAL) model was developed with 6 predictors (preoperative albumin, blood urea nitrogen, American Society of Anaesthesiology score, sepsis or septic shock, dependent functional status, and ascites). SEAL had good discriminative ability (optimism-corrected c-statistic: 0.80, 95% confidence interval [CI] 0.79-0.81), calibration (optimism-corrected calibration slope: 1.01, 95% CI 0.99-1.03) and overall fit (scaled Brier score: 25.1%, 95% CI 24.1-26.1%). SEAL compared favourably with ACS-NSQIP in all metrics, including DCA across multiple risk thresholds. CONCLUSION SEAL is a simple and promising model for individualized risk predictions of serious complications after EL. Future external validations should appraise SEAL's transportability across diverse settings.

Abstract
Sentinel lymph node biopsy (SLNB) has become the standard of care for clinically node-negative breast cancer and has recently been shown by clinical trials to be also feasible for clinically node-positive patients treated with primary systemic therapy. The dual technique using both radioisotope (RI) and blue dye (BD) as tracers for the identification of sentinel lymph nodes is considered the gold standard. However, allergic reactions to blue dye as well as logistics issues related to the use of radioactive agents, have led to research on new sentinel lymph node (SLN) tracers and to the development and introduction of novel techniques in the clinical practice. Indocyanine green (ICG) is a water-soluble dye with fluorescent properties in the near-infrared (NIR) spectrum. ICG has been shown to be safe and effective as a tracer during SLNB for breast cancer and accumulating evidence suggests that ICG is superior to BD and at least comparable to RI alone and to RI combined with BD. Thus, ICG was recently proposed as a reliable SLN tracer in some breast cancer clinical practice guidelines. Nevertheless, there is lack of consensus regarding the optimal role of ICG for SLN mapping. Specifically, it is yet to be determined whether ICG should be used in addition to BD and/or RI, or if ICG could potentially replace these long-established traditional SLN tracers. This article is an updated overview of somerecent studies that compared ICG with BD and/or RI regarding their accuracy and effectiveness during SLNB for breast cancer.

Abstract
Assessment of regional lymph node status in breast cancer is of important staging and prognostic value. Even though formal histological examination is the currently accepted standard of care, optical imaging techniques have shown promising results in disease diagnosis. In the present article, we review six spectroscopic techniques and focus on their use as alternative tools for breast cancer lymph node assessment. Elastic scattering spectroscopy (ESS) seems to offer a simple, cost-effective, and reproducible method for intraoperative diagnosis of breast cancer lymph node metastasis. Optical coherence tomography (OCT) provides high-resolution tissue scanning, along with a short data acquisition time. However, it is relatively costly and experimentally complex. Raman spectroscopy proves to be a highly accurate method for the identification of malignant axillary lymph nodes, and it has been further validated in the setting of head and neck cancers. Still, it remains time-consuming. Near-infrared fluorescence imaging (NIRF) and diffuse reflectance spectroscopy (DFS) are related to significant advantages, such as deep tissue penetration and efficiency. Fourier-transform infrared spectroscopy (FTIR) is a promising method but has significant drawbacks. Nonetheless, only anecdotal reports exist on their clinical use for cancerous lymph node detection. Our results indicate that optical imaging methods can create informative and rapid tools to effectively guide surgical decision-making.

Abstract
BACKGROUND Accurate preoperative risk assessment in emergency laparotomy (EL) is valuable for informed decision making and rational use of resources. Available risk prediction tools have not been validated adequately across diverse health care settings. Herein, we report a comparative external validation of four widely cited prognostic models. METHODS A multicenter cohort was prospectively composed of consecutive patients undergoing EL in 11 Greek hospitals from January 2020 to May 2021 using the National Emergency Laparotomy Audit (NELA) inclusion criteria. Thirty-day mortality risk predictions were calculated using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), NELA, Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM), and Predictive Optimal Trees in Emergency Surgery Risk tools. Surgeons' assessment of postoperative mortality using predefined cutoffs was recorded, and a surgeon-adjusted ACS-NSQIP prediction was calculated when the original model's prediction was relatively low. Predictive performances were compared using scaled Brier scores, discrimination and calibration measures and plots, and decision curve analysis. Heterogeneity across hospitals was assessed by random-effects meta-analysis. RESULTS A total of 631 patients were included, and 30-day mortality was 16.3%. The ACS-NSQIP and its surgeon-adjusted version had the highest scaled Brier scores. All models presented high discriminative ability, with concordance statistics ranging from 0.79 for P-POSSUM to 0.85 for NELA. However, except the surgeon-adjusted ACS-NSQIP (Hosmer-Lemeshow test, p = 0.742), all other models were poorly calibrated ( p < 0.001). Decision curve analysis revealed superior clinical utility of the ACS-NSQIP. Following recalibrations, predictive accuracy improved for all models, but ACS-NSQIP retained the lead. Between-hospital heterogeneity was minimum for the ACS-NSQIP model and maximum for P-POSSUM. CONCLUSION The ACS-NSQIP tool was most accurate for mortality predictions after EL in a broad external validation cohort, demonstrating utility for facilitating preoperative risk management in the Greek health care system. Subjective surgeon assessments of patient prognosis may optimize ACS-NSQIP predictions. LEVEL OF EVIDENCE Diagnostic Test/Criteria; Level II.

Abstract
BACKGROUND Shared decision-making (SDM) between clinicians and patients is one of the pillars of the modern patient-centric philosophy of care. This study aims to explore SDM in the discipline of trauma and emergency surgery, investigating its interpretation as well as the barriers and facilitators for its implementation among surgeons. METHODS Grounding on the literature on the topics of the understanding, barriers, and facilitators of SDM in trauma and emergency surgery, a survey was created by a multidisciplinary committee and endorsed by the World Society of Emergency Surgery (WSES). The survey was sent to all 917 WSES members, advertised through the society's website, and shared on the society's Twitter profile. RESULTS A total of 650 trauma and emergency surgeons from 71 countries in five continents participated in the initiative. Less than half of the surgeons understood SDM, and 30% still saw the value in exclusively engaging multidisciplinary provider teams without involving the patient. Several barriers to effectively partnering with the patient in the decision-making process were identified, such as the lack of time and the need to concentrate on making medical teams work smoothly. DISCUSSION Our investigation underlines how only a minority of trauma and emergency surgeons understand SDM, and perhaps, the value of SDM is not fully accepted in trauma and emergency situations. The inclusion of SDM practices in clinical guidelines may represent the most feasible and advocated solutions.

Abstract
BACKGROUND Emergency laparotomy (EL) is accompanied by high post-operative morbidity and mortality which varies significantly between countries and populations. The aim of this study is to report outcomes of emergency laparotomy in Greece and to compare them with the results of the National Emergency Laparotomy Audit (NELA). METHODS This is a multicentre prospective cohort study undertaken between 01.2019 and 05.2020 including consecutive patients subjected to EL in 11 Greek hospitals. EL was defined according to NELA criteria. Demographics, clinical variables, and post-operative outcomes were prospectively registered in an online database. Multivariable logistic regression analysis was used to identify independent predictors of post-operative mortality. RESULTS There were 633 patients, 53.9% males, ASA class III/IV 43.6%, older than 65 years 58.6%. The most common operations were small bowel resection (20.5%), peptic ulcer repair (12.0%), adhesiolysis (11.8%) and Hartmann's procedure (11.5%). 30-day post-operative mortality reached 16.3% and serious complications occurred in 10.9%. Factors associated with post-operative mortality were increasing age and ASA class, dependent functional status, ascites, severe sepsis, septic shock, and diabetes. HELAS cohort showed similarities with NELA patients in terms of demographics and preoperative risk. Post-operative utilisation of ICU was significantly lower in the Greek cohort (25.8% vs 56.8%) whereas 30-day post-operative mortality was significantly higher (16.3% vs 8.7%). CONCLUSION In this study, Greek patients experienced markedly worse mortality after emergency laparotomy compared with their British counterparts. This can be at least partly explained by underutilisation of critical care by surgical patients who are at high risk for death.

Abstract
BACKGROUND The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. METHODS Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. RESULTS A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. CONCLUSIONS The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands.

Abstract
The harsh healthcare reality imposed by the COVID-19 pandemic resulted in wide clinical practice alterations, postponements, and shortages, affecting both patients and caregivers. Breast-cancer management, from diagnosis to treatment and follow up, was a field that did not escape such changes, facing a challenging set of obstacles in order to maintain adequate cancer care services while diminishing viral spread among patients and personnel. In this review article, we discuss the impact of the COVID-19 pandemic on several aspects of breast-cancer management, and the subsequent modifications adopted by clinicians, scientific groups, and governments as a response to the novel conditions. Screening and diagnosis, as well as breast-cancer treatment paths-especially surgical interventions-were the most affected domains, while patients' psychological burden also emerged as a notable consequence. The aftermath of diagnostic and surgical delays is yet to be assessed, while the treatment alterations and the introduction of new therapeutic schemes might signify the opening of a novel era in breast-cancer management.

Abstract
BackgroundManaging postoperative pain even after laparoscopic groin hernia repair still remains an interesting challenge for clinicians especially for patients of high risk. Plenty of operative techniques and analgesic methods have been proposed in order to minimize postoperative pain after laparoscopic groin hernia repair. The aim of the present study is to compare transverse abdominis plane (TAP)-block with local analgesic infiltration at trocar entry sites in the terms of reducing postoperative pain.MethodsPatients that underwent laparoscopic trans-abdominal pre-peritoneal (TAPP) groin hernia repair in a high-volume university hospital were included. Patients were divided in two groups depending on the analgesic method used. Pain was assessed using Visual Numerical Scale (VNS) score.ResultsThirty patients were included. Intraoperative TAP-block seemed to be superior in terms of decreasing pain at the hernia area and at the trocar insertion site (p < 0.05) compared to local analgesic infiltration at the trocar insertion site at 6, 12 and 24 h after surgery (p < 0.05). In addition, pain reduction was more effective in rest rather than in motion for both analgesic methods.ConclusionIntraoperative TAP-block under direct vision seems to be an effective, fast and easy technique in order to reduce postoperative pain after laparoscopic groin hernia repair, but more studies are required to validate these results in a prospective and randomized context.

Abstract
BACKGROUND Despite the dominance of implant-based breast reconstruction after mastectomy, during recent years, it has been correlated to some complications. The aim of this study is to present the Greek experience about management of implant infections after breast reconstructions and to investigate the relationship between possible risk factors and breast pocket fluid cultures. METHODS In total, 260 patients underwent implant-based breast reconstruction due to breast cancer in our center from 2016 until 2020. 46 patients, that underwent implant or expander replacement after breast reconstruction due to mastectomy were included in the present study. RESULTS 260 patients underwent breast reconstruction in our center and in 46 (18%) of them an implant replacement was required. 21 patients (8%) presented clinically with an implant infection, but 12 of them (5%) had positive cultures from the breast pocket fluid. On the contrary, 25 patients (10%) presented no clinical signs of implant infection, but 5 of them (2%) had a positive culture. In addition, we demonstrated a correlation between implant infection and positive cultures (p = 0.009), along with an association between chemotherapy before implant placements and negative cultures (p = 0.035). Finally, the most common pathogen was Staphylococcus epidermidis (29%), followed by Escherichia coli (24%) and Staphylococcus aureus (18%). CONCLUSION Implant infection still remains a very serious complication after breast reconstruction surgery. The establishment of a therapeutic protocol, with specific antimicrobial and surgical targets seems as an effective strategy against implant infections.

Abstract
Aberrant Wnt signaling is implicated in carcinogenesis triggering efforts for the development of new therapeutic agents, many of which have entered clinical trials. We extend our previous analysis of WNT3, FZD7, LEF1 expression levels in breast and colorectal cancer including WNT2, FZD4 and β-catenin expression, in an effort to delineate their relative expression levels along with concurrent expression patterns and possible prognostic value. We analyzed 82 breast and 102 colorectal carcinomas for relative mRNA expression levels of the investigated genes by RT-PCR relative quantification with the ΔΔCt method. Statistical analysis was performed in order to determine associations of relative mRNA expression and linear correlations. β-catenin expression was determined by immunochemistry. Regarding breast carcinomas, decreased relative mRNA expression levels of WNT2, FZD4 were found frequently and WNT2 expression was correlated with ER/ PR status (p = 0.045/p = 0.028), whereas β-catenin with grade (p = 0.026). In colorectal carcinomas, increased relative mRNA expression levels of WNT2 and FZD4 were found in 59% and 32% of cases respectively, whereas β-catenin showed decreased mRNA expression levels in 57% of cases and a correlation with pN-category (p = 0.037). Linear correlations were observed between WNT2/FZD4 (R=0.542, p < 0.001), WNT2/β-catenin (R=0.254, p = 0.010), FZD4/β-catenin (R=0.406, p < 0.001) expression and a correlation between mRNA expression and membranous/cytoplasmic β-catenin emerged (p = 0.039/0.046). Our results suggest a possible clinical significance for Wnt pathway gene expression levels in both tumour types. The concurrent expression of the investigated genes as well as the different expression profiles, underlines the complexity of this pathway and the necessity of patient selection in order to maximize the efficacy of drugs targeting Wnt pathway.

Abstract
Preoperative hook localization is a necessary procedure for targeting impalpable breast lesions. The aim of the current study is to introduce an alternative technique of wire placement by using the stereotactic biopsy device instead of the conventionally used mammography device. Fifty-one patients with impalpable mammographic lesions, graded BIRADS 4 or 5, were prospectively enrolled. Mean duration was 7 ± 1.5 minutes. Lesion-to-wire distance was <1 cm in 96% (51/53). Hook wire placement using the stereotactic biopsy device is considered as a safe, accurate, fast, and well-tolerable for the patient procedure.

Abstract
Breast metastasis originating from non-mammary tumors is an uncommon event accounting for 0.5-6.6% of all breast neoplasms. The primary malignancies that reportedly metastasize to the breast most frequently are hematologic malignancies, such as leukemia and lymphoma and malignant melanoma. Breast cancer metastasis resulting from a primary lung neoplasm is significantly less commonly described in the literature. Herein, we present the unusual case of a patient with metastatic disease to the breast from a primary lung tumor.

Abstract
BACKGROUND Kounis syndrome (KS) has been described as an acute coronary syndrome (ACS) associated with an anaphylactic reaction. Several triggers have been identified and the diagnostic and treatment process can be challenging. CASE A 58-year-old, female patient diagnosed with breast cancer and no history of allergies had subcutaneous injection of patent blue V dye for sentinel lymph node biopsy (SLNB). Intraoperatively, she developed anaphylactic shock and was transferred to the intensive care unit (ICU). A few hours later, electrocardiographic alterations and elevation of blood troponin were observed. Emergency coronary angiography revealed no occlusive lesions in coronary vessels. Further investigation in the allergy department set the diagnosis of KS. CONCLUSION There are just ten cases of perioperative KS in the literature so far and here we present the first one triggered by patent blue V dye for sentinel node biopsy.

Abstract
Wnt signaling pathway regulates important cell functions such as proliferation and migration and is frequently deregulated in colorectal and breast cancer. Thus, it constitutes an attractive therapeutic target with many drugs being investigated in clinical trials. Eighty-two breast and 102 colorectal carcinomas were analyzed for: relative mRNA expression levels of Wnt pathway components namely Wnt3 ligand, Frizzled 7 receptor and LEF1 transcriptional factor, their concurrent expression patterns and their correlation with clinicopathological features. Regarding breast carcinomas, increased relative mRNA expression levels of WNT3 were found in 54 % of cases whereas decreased relative mRNA expression levels were observed in FZD7 and LEF1 in 82 % and 43 % of cases, respectively. Expression levels of WNT3 were significantly correlated with tumour grade (p = 0.021) in breast cancer. As far as colorectal carcinomas are concerned, increased relative mRNA expression levels of WNT3, FZD7 and LEF1 were found in 60 %, 37 % and 48 % of cases respectively. A statistically significant correlation emerged between LEF1expression levels and pT-category (p = 0.027), suggesting a possible association with tumour aggressiveness in colorectal carcinomas. Statistically significant linear correlations were observed between the expression of WNT3/LEF1 (R = 0.233, p = 0.035) and FZD7/LEF1 (R = 0.359, p = 0.001) in breast carcinomas as well as in colorectal carcinomas (R = 0.536, p < 0.01 and R = 0.210, p = 0.034) respectively. Our results demonstrate a possible clinical significance of Wnt pathway gene expression levels in both tumour types. The distinct expression patterns and simultaneous expression of the investigated genes underscore the complexity of this pathway in breast and colorectal carcinogenesis and highlights the necessity of patient selection with regard to the effectiveness of Wnt pathway inhibitors.

Abstract
Giant phyllodes tumors are rare fibroepithelial breast neoplasms typically >10 cm by definition. The best investigation for preoperative diagnosis is core biopsy, although it is often difficult for the pathologist to distinguish fibroadenomas from phyllodes tumors and determine the level of malignant potential. The wide excision is the appropriate therapy for phyllodes tumors taking into consideration that mastectomy may be required for huge phyllodes tumors. In the modern era of breast tissue expanders and breast implants, immediate breast reconstruction is feasible. We present a case report of a patient with a giant phyllodes tumor of 24 cm diameter who underwent mastectomy and immediate breast reconstruction with breast tissue expander.

Abstract
PURPOSE Access to nuclear medicine department for sentinel node imaging remains an issue in number of hospitals in the UK and many parts of the world. Sentinella® is a portable imaging camera used intra-operatively to produce real time visual localisation of sentinel lymph nodes. METHODS Sentinella® was tested in a controlled laboratory environment at our centre and we report our experience on the first use of this technology from UK. Moreover, preoperative scintigrams of the axilla were obtained in 144 patients undergoing sentinel node biopsy using conventional gamma camera. Sentinella® scans were done intra-operatively to correlate with the pre-operative scintigram and to determine presence of any residual hot node after the axilla was deemed to be clear based on the silence of the hand held gamma probe. RESULTS Sentinella® detected significantly more nodes compared with CGC (p < 0.0001). Sentinella® picked up extra nodes in 5/144 cases after the axilla was found silent using hand held gamma probe. In 2/144 cases, extra nodes detected by Sentinella® confirmed presence of tumour cells that led to a complete axillary clearance. CONCLUSIONS Sentinella® is a reliable technique for intra-operative localisation of radioactive nodes. It provides increased nodal visualisation rates compared to static scintigram imaging and proves to be an important tool for harvesting all hot sentinel nodes. This portable gamma camera can definitely replace the use of conventional lymphoscintigrams saving time and money both for patients and the health system.

Abstract
Among the numerous signaling pathways involved in tumorigenesis, PI3K-AKT-mTOR is a key one that regulates diverse cellular functions. However, its prognostic value in esophageal carcinoma remains unclear. In our study, we examined the immunohistochemical expression of phosphorylated (p-) AKT, mTOR, p70S6K and 4E-BP1 along with the mutational status of PIK3CA and AKT1 genes by High Resolution Melting Analysis and Pyrosequencing in 44 esophageal carcinomas. The results were correlated with the clinicopathological characteristics of the patients in an effort to define their possible prognostic significance. Total p-mTOR cytoplasmic expression, assessed in 10 random areas, was positively correlated with tumor stage (Kruskal-Wallis ANOVA, I/II vs III/IV, p = 0.0500). Μoreover, maximum p-mTOR cytoplasmic immunoexpression, estimated in hot spot areas, was positively associated with tumor grade (Mann-Whitney U test, I/II vs III, p = 0.0565). Interestingly, p-4E-BP1 immunoreactivity was negatively correlated with tumor histological grade (Mann-Whitney U test, I/II vs III, p = 0.0427). No mutation was observed in exons 9 and 20 of PIK3CA gene and in exon 4 of AKT1 gene. In conclusion, our findings depict the presence of activated PI3K/AKT/mTOR pathway in esophageal cancer bringing forward p-mTOR and p-4E-BP1 for their potential role in esophageal carcinogenesis. Additional studies are warranted to validate our findings.

Abstract
Abstract
Introduction: Access to nuclear medicine department and sentinel node imaging remain an issue in number of hospitals. Preoperative Scintigrams are performed to confirm uptake of radioactivity and localisation of nodes in centres where facilities are available. Sentinella® (Oncovision, Valencia, Spain) is a recently introduced portable imaging gamma camera used intraoperatively to produce real time visual localisation of SLNs. Sentinella® was tested in a controlled laboratory environment and we report the first use of this technique in breast cancer patients from UK.
Methods: In the laboratory setting our aim was to compare the sensitivity and spatial resolution of the Sentinella® and a conventional gamma camera (cGC) used for sentinel node imaging by comparing it with the performance of a GE multi-purpose rectangular (MPR) conventional single head gamma camera normally used for sentinel node imaging. A simulator containing seeds 10kBq, 100kBq, 500kBq of radiocolloid Tc, mimicking SLN, were used. Seeds were placed at several depths in the axilla, at 3cm, 5cm and 8cm from the skin. Sentinella was placed first at 10cm and then 1cm away from the axilla and images were recorded at 1min and at 2.5min for every position. The cGC was placed 20 cm away from the simulator.
Results: 68 Sentinella® images and 34 cGC images obtained from the simulated axilla. Sentinella® resolution is comparable with the cGC for objects close to the camera i.e. ∼ 5 cm, but reduces rapidly as it's moved away from the camera. For distances up to about 7 cm the Sentinella® with the blue collimator is more sensitive than the cGC. Sentinella detects high radioactivity (500 kBq) faster than cGC (1 vs 2.5min). In cases of low radioactivity (10kBq) Sentinella® was equally accurate and faster than cGC, when placed close to the skin. Identification of different number of beads with varying radioactivity was similar in Sentinella and cGC. Sentinella scans of the axilla were obtained in 85 patients undergoing SLNB. All patients had a preoperative lymphoscintigram. Serial Sentinella scans were obtained after removal of every hot node. Sentinella scans correlated with all the lymphoscintigrams in the 85 cases studied. Serial decay in activity was seen with removal of every hot node. Extra nodes were picked up in 6/85 cases after the axilla was found silent using hand held gamma probe. In 2/85 cases extra nodes found had cancer that led to axillary clearance. Sentinella scans were extremely useful in differentiating between a hot sentinel node and signal from injection site in upper outer quadrants of small sized breasts.
Conclusion: Sentinella is accurate and fast in detecting radioactivity in the axilla. The anatomical shape of its collimator allows the operator to place it close to the axilla thus increasing sensitivity in cases of low radioactivity. Our independent tests and initial patient data confirm the excellent sensitivity and specificity. It's major advantage is that it can be used by surgeons to scan for residual nodes before completion of the procedure. It can resolve the problem of centres that do not have nuclear medicine departments. This portable gamma camera can definitely replace the use of conventional lymphoscintigrams saving time and money both for patients and the Hospital.

Abstract
Submucosal hemorrhoidectomy (Parks’ procedure) is a recognized method for treating acute hemorrhoidal crisis. Anoderm preservation has been stressed in various techniques described for elective or emergency excisional hemorrhoidal management. Mucopexy techniques have been proven useful as an adjunct to minimally resectional techniques. A modified submucosal technique with anoderm preservation and mucopexy was applied to 45 patients who presented on an emergency basis with hemorrhoidal crisis. External piles were minimally removed, the minimum possible amount of diseased mucosa was excised, a linear incision was used at the anoderm to enter the subanodermal/mucosal plane to achieve the submucosal excision, and a mucopexy was added at the approximation of the mucosal flaps. Postoperative morbidity was minimal and pain after the procedure remained at acceptable levels. This technique allows for an excision limited to the pathology with important anatomic tissue preservation. This results in conservation of the sensitive and useful anoderm, a decreased risk of stenosis, and addresses the mucosal prolapse. The level of postoperative pain with this technique is acceptable and long-term follow-up reveals a high degree of patient satisfaction.

Abstract
BACKGROUND AND OBJECTIVES Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. METHODS Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. RESULTS Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5 3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. CONCLUSION Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

Abstract
PURPOSE Laparoscopic colectomy has been reported as a safe and oncologically similar operation to open colectomy. A number of expensive surgical instruments are necessary for the procedure which should be applied if it is cost-effective for the patient and the health system in general. The purpose of the current study was the economic evaluation of laparoscopic compared to open colectomy for the treatment of colon cancer in the Greek national health system. METHODS Fifty patients undergoing open colectomy and 42 undergoing laparoscopic colectomy were enrolled in this case-control study. Length of hospital stay, duration of operation, complication rates, cost of equipment used, total costs and three questionnaires measuring quality of life /QoL (EQ-5D, SF-36 and QLQ-C30) at baseline, 1 and 3 months after the operation were recorded. RESULTS No statistically significant difference in QoL measured by QALYs between laparoscopic and open colectomy was observed. On the other hand, cost utility analysis revealed that laparoscopic colectomy was more expensive considering the advantages it offers. CONCLUSIONS Laparoscopic colectomy is not superior to open colectomy on a QoL basis in the Greek public hospital system and is less cost-effective compared to the open procedure. Since the expensive equipment used in laparoscopic colectomy seems to be the causative factor for the high cost of this type of operation, an effort should be made to reduce it either by using reusable instruments or by implementing policies aiming at suppliers cutting down equipment charges.

Abstract
Breast cancer is prone to metastasis even in early stage disease. Stromal cell-derived factor-1 (SDF-1) is a chemokine that has been associated with the egress of cancer cells from the primary focus and homing to distant sites, while E-selectin has been implicated in their trans-endothelial migration. This study was performed to evaluate the association between SDF-1-3'A and E-selectin S128R-two polymorphisms associated with enhanced function-and the risk of breast cancer, as well as their influence on breast cancer outcome. A retrospective analysis was conducted on 261 patients and 480 healthy controls using PCR-RFLP. The frequencies for the wild-type (GG), GA and AA genotypes of SDF-1 were 43.7, 45.2, and 11.1 % in patients, and 51.5, 41.3, and 7.3 % in healthy controls, respectively, while the SDF-1-3'A allelic frequency was 33.7 % at patients and 27.9 % at controls. The SDF-1-3'A carrier group of patients and the A allele of SDF-1 were overrepresented among the breast cancer cases (p = 0.04 and 0.02, respectively). For the E-selectin S128R polymorphism, the frequencies for the wild-type (AA), AC and CC genotypes were 58.6, 38.3, and 3.1 % in patients and 63.8, 31.4, and 3.8 % in controls, respectively, while the C allelic frequency was 22.2 % for patients and 19.5 % for controls. The CC genotype was associated with poorer survival. Otherwise, no significant association was detected between examined genotypes and tumor characteristics. Overall, our findings support that the SDF-1-3'A confers increased susceptibility to breast cancer and that the E-selectin S128R CC genotype may be related to poorer prognosis. Investigation in bigger cohorts of patients is warranted.

Abstract
Stromal cell derived factor-1 (SDF-1), a CXC chemokine that plays an important role in the tumor growth, angiogenesis and metastasis of tumor cells, has a polymorphism at position 801 of its 3'-untranslated region, known as SDF1-3'A. The SDF1-3'A polymorphism has been investigated in various types of cancer, but no information is currently available on its role in pancreatic cancer. In this study, 80 pancreatic cancer patients and 160 normal healthy control subjects were investigated for the genotype and allelic frequencies of the SDF-1 gene using PCR-RFLP. The genotype frequencies for GG, GA and AA were 21.25, 77.5 and 1.25% in patients, and 42.5, 55 and 2.5% in healthy subjects, respectively. The A carrier group (GA+AA genotype) and the A allele were overrepresented among the patients with pancreatic cancer (p=0.015 and p=0.031, respectively). The GA+AA genotype was statistically correlated with an advanced T stage and the presence of lymph node metastasis, and displayed a clear trend towards significance in relation to the presence of distant metastatic disease (p=0.061). Only T stage was significantly related to A allele frequency (p=0.004). SDF1-3' A allele carriers were more prevalent among cancer patients than among normal subjects. SDF1-3' A allele carrier status may imply a higher risk of pancreatic cancer, while the presence of the A allele in pancreatic cancer patients may be related to aggressive features of this malignancy.

Abstract
Caspases (CASPs), play a crucial role in the development and progression of cancer. We evaluated the association between two polymorphisms (rs4645978 and rs4645981) of the CASP9 gene and the risk of breast cancer (BC). Genotypes and allelic frequencies for the two polymorphisms were determined in 261 patients with breast cancer and 480 healthy controls. Polymerase chain reaction-restriction fragment length polymorphisms were used, and statistical significance was determined by the χ(2) test. Carriers of the rs4645978G allele (AG and GG genotypes) were at higher risk for BC than individuals with other genotypes (odds ratio (OR) 1.59, 95% confidence interval (CI) 1.07-2.37, P = 0.022). The rs4645978GG genotype, in particular, was associated with the highest risk for BC development (OR 2.25, 95% CI 1.45-3.49, P = 0.0003). Similarly, individuals with at least one rs4645981T allele were at a significantly increased risk of developing BC compared with those harboring the CC genotype (OR 2.75, 95% CI 1.99-3.78, P < 0.0001), and the risk of BC increased with increasing numbers of rs4645981T alleles (OR 2.66, 95% CI 1.91-3.69, P < 0.0001 for the CT genotype; OR 3.95, 95% CI 1.58-9.88, P = 0.004 for the TT genotype). The CASP9 promoter polymorphisms rs4645978 and rs4645981 are associated with BC susceptibility and suggest that CASP9 transcriptional regulation is an important factor during BC development.

Abstract
MAPK (mitogen-activated protein kinase) pathway is considered a control regulator in various malignant tumors but its role in esophageal carcinomas remains elusive. In our study, we examined the possible prognostic significance of MAPK pathway in human esophageal cancer. We searched for mutations in exons 18-21 of EGFR gene, codons 12 and 13 of K-RAS gene and exon 15 of B-RAF gene by high resolution melting analysis (HRMA) and pyrosequencing in 44 esophageal carcinomas. Immunohistochemistry was performed in 29 cases in order to evaluate expression levels of pERK (extracellular-signal regulated kinase). In one laser microdissected squamous cell carcinoma, a somatic K-RAS mutation at codon 12 was detected, whereas none of the cases displayed mutations in EGFR and B-RAF genes. Elevated nuclear as well as cytoplasmic pERK expression (100% and 62% of cases respectively) was observed independently of EGFR and B-RAF mutational status. Increasing pERK nuclear and cytoplasmic expression as well as the intensity of nuclear staining was found to be significantly correlated with tumor grade in univariate and multivariate statistical analysis. Our findings depict the presence of activated ERK despite the low frequency of upstream alterations, implicating ERK activation in the acquisition of a more aggressive phenotype in esophageal cancer.

Abstract
Giant paraesophageal hernias (PEHs) are associated with progression of symptoms in up to 45 per cent of patients. Recently, many series have reported that laparoscopic repair of PEH is technically feasible, effective, and safe. A retrospective review of the University of Athens tertiary care hospitals patient database and the patient medical records identified 45 patients who underwent elective repair of a giant PEH between 2002 and 2009. Elective laparoscopic repair of a giant PEH was attempted in 45 patients who were treated with Gore-Tex dual mesh with or without Nissen fundoplication. They all had a mesh repair. Intraoperative complications included one pulmonary embolism and one recurrent hernia. The use of a mesh seems to be effective in the treatment of large hernias. It appears to offer the benefit of a shorter hospital stay and a quicker recovery.

Abstract
BACKGROUND Colorectal (CRC) carcinogenesis through various morphological stages has been linked to several genetic and epigenetic changes. The Raf/MEK/ERK (MAPK) signal transduction cascade is an important mediator of a number of cellular fates. METHODS In this study, we investigated the presence of B-raf and K-ras mutations in 94 consecutive cases of primary colon adenocarcinoma in correlation with the immunohistochemical expression of total and activated ERK and the expression of mismatch repair proteins (MMR) hMLH1 and hMSH2 as well as their correlations with standard clinicopathological parameters. RESULTS The immunostaining pattern for total and activated ERK was nuclear and cytoplasmic. hMLH1 and hMSH2 proteins were preserved in 45/63 (71.43%) cases and 35/53 (66.04%) cases respectively. Total ERK nuclear expression, was positively correlated with tumor stage (p = 0.049), whereas nuclear pERK expression was positively correlated with histological grade (p = 0.0113) and tumor stage (p = 0.0952), although the latter relationship was of marginal significance. DNA sequencing showed that 12 samples (12.7%) had a mutation in B-RAF Exon 15 and none in Exon 11, whereas 22 (23.4%) had a K-ras mutation. Disruption of the MAP kinase pathway-either through K-ras or B-raf mutation-was detected in 37% of all the examined cases, although the overexpression of total and activated ERK1/2 was not correlated with the mutational status of K-ras or B-raf genes. Finally, the preservation of hMLH1 or hMSH2 immunoexpression was not correlated with the presence of B-raf and/or K-ras mutations. CONCLUSIONS In this study, we present evidence that ERK activation occurs in a K-ras or B-raf -independent manner in the majority of primary colon cancer cases. Moreover, B-raf mutations are not associated with mismatch-repair deficiency through loss of hMLH1 or hMSH2 expression. Activated ERK could possibly be implicated in tumor invasiveness as well as in the acquisition of a more aggressive phenotype.

Abstract
BACKGROUND Vacuum-assisted breast biopsy (VABB) is used for the diagnosis of non-palpable breast lesions. Hematoma has been recognized as the main complication of the procedure. Its main disadvantage is the underestimation rate. Generally speaking, approximately up to 24 cores are excised in most published series. It has been suggested that excision of more cores per lesion can reduce the underestimation rate. The present study aims to evaluate hematoma formation with regard to the number of cores excised. PATIENTS AND METHODS A total of 660 women underwent VABB; 232 women were allocated to the standard protocol (24-36 cores excised, 2-3 offsets) and 428 women were allocated to the extended protocol (96 cores excised, 8 offsets). Cases were derived from a double blind study, as well as from the periods before (standard protocol) and after (mainly extended protocol) the study. In all cases, the occurrence of organized hematomas within the subsequent 20 days was followed up by ultrasound. RESULTS In the standard protocol, the frequency of clinically significant and subsequently organized hematomas was 3.5%. However, in the extended protocol the respective hematoma percentage was 7.5%. Clinically significant and subsequently organized hematomas were significantly more frequent in the extended protocol (Pearson's chi-squared=4.29, p=0.038). CONCLUSION Despite the superiority of the extended protocol in terms of underestimation, the approximately two-fold increase in hematoma occurrence prompts the need for careful patient selection prior to its performance.

Abstract
BACKGROUND E-selectin, an intercellular adhesion molecule that plays important roles in metastasis of tumor cells, has a polymorphism in exon 4 that results in the substitution of a serine by an arginine within the extracellular domain of the receptor, which increases its affinity for ligands. No evidence exist on the role of E-selectin polymorphism in pancreatic cancer. METHODS Eighty pancreatic cancer patients and 160 cases of normal healthy control subjects were investigated for genotype and allelic frequencies of S128R polymorphism of E-selectin gene by PCR-RFLPs. RESULTS The frequencies for "AA," "CA," and "CC" genotypes were 46.25%, 50%, and 3.75% in patients, and 63.75%, 26.9%, and 9.4% in healthy subjects, respectively. The "C" carriers group of patients ("CA + CC" genotype) and the "C" allele were over-represented among the pancreatic cancer cases (P = 0.012 and 0.096, respectively). Advanced T stage, the presence of lymph node and other adverse pathologic characteristics were not significantly correlated with either the "CA + CC" genotype group of patients or the presence of "C" allele. CONCLUSIONS E-selectin S128R "C" allele may confer an increased susceptibility to pancreatic cancer development, while its carriage status does not appear to be related to the aggressive features of this malignancy.

Abstract
BACKGROUND Despite their safety and effectiveness in thyroid surgery, the previous harmonic scalpel instruments are considered large and cumbersome by several surgeons. An innovative technical improvement of the device has been made available since 2008. The objective of this study was to compare the results of total thyroidectomy using the new harmonic scalpel (FOCUS) with that with the previously available device (HARMONIC ACE). METHODS A prospective randomized study of all total thyroidectomies between February and July 2008 was conducted. Patients (n = 90) were randomized to undergo total thyroidectomy with FOCUS (group A, n = 45) or HARMONIC ACE (group B, n = 45). RESULTS No significant differences were identified between the 2 groups in terms of demographics, reoperative thyroid surgery, thyroid gland weight and diameter, pathologic diagnosis, preoperative and postoperative serum PTH and calcium levels, postoperative complications, duration of hospital stay, and final outcome. The mean operative time was less in group A than group B (63 ± 7 min vs 76 ± 8 min, P = .009). CONCLUSION The new harmonic scalpel is a useful adjunct to the armamentarium of the thyroid surgeon. It is safe, effective, and hand friendly, offering great capabilities for delicate tissue grasping and dissection. Use of this device decreased operative time compared with the previously available instrument.

Abstract
BACKGROUND Elevated Hsp90 expression has been documented in breast ductal carcinomas, whereas decreased Hsp90 expression has been reported in precursor lobular lesions. This study aims to assess Hsp90 expression in infiltrative lobular carcinomas of the breast. METHODS Tissue specimens were taken from 32 patients with infiltrative lobular carcinoma. Immunohistochemical assessment of Hsp90 was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. Concerning Hsp90 assessment: i) the percentage of positive cells and ii) the intensity were separately analyzed. Subsequently, the Allred score was adopted and calculated. The intensity was treated as an ordinal variable-score (0: negative, low: 1, moderate: 2, high: 3). Statistical analysis followed. RESULTS All infiltrative lobular carcinoma foci mainly presented with a positive cytoplasmic immunoreaction for Hsp90. Compared to the adjacent normal ducts and lobules, infiltrative lobular carcinoma exhibited a statistically significant decrease in Hsp90 expression, both in terms of Hsp90 positive cells (%) and Allred score (74.2 +/- 11.2 vs. 59.1 +/- 14.2 p = 0.0001; 7.00 +/- 0.95 vs. 6.22 +/- 1.01, p = 0.007, Wilcoxon matched-pairs signed-ranks test). Concerning the intensity of Hsp90 immunostaining only a marginal decrease was noted (2.16 +/- 0.68 vs. 1.84 +/- 0.63, p = 0.087, Wilcoxon matched-pairs signed-ranks test). CONCLUSION ILC lesions seem to exhibit decreased Hsp90 expression, a finding contrary to what might have been expected, given that high Hsp90 expression is a trait of invasive ductal carcinomas.

Abstract
BACKGROUND Hsp90 (heat shock protein90) is a chaperone protein essential for preserving and regulating the function of various cellular proteins. Elevated Hsp90 expression seems to be a trait of breast cancer and may be an integral part of the coping mechanisms that cancer cells exhibit vis-à-vis stress. This manuscript tries to examine the immunohistochemical expression of Hsp90 all along the continuum of breast ductal lesions encompassing ductal hyperplasia without atypia (DHWithoutA), atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC). METHODS Tissue specimens were taken from 30 patients with DHWithoutA, 31 patients with ADH, 51 with DCIS and 51 with IDC. Immunohistochemical assessment of Hsp90 was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. Concerning Hsp90 assessment the percentage of positive cells and the intensity were separately analyzed. Subsequently, the Allred score was calculated. Post hoc analysis on the correlations between Hsp90 Allred score and possible predictors (grade, nodal status, tumor size, ER Allred score, PR Allred score, c-erbB-2 status and triple negative status) was conducted in IDC. RESULTS Hsp90 exhibited mainly cytoplasmic immunoreactivity. Hsp90 Allred score exhibited an increasing trend along the continuum of breast ductal lesions (Spearman's rho = 0.169, p = 0.031). Compared to the adjacent normal ducts and lobules, no statistically significant differences were noted in DHwithoutA, ADH and DCIS. Hsp90 expression (intensity, positive cells, Allred score) was higher in IDC, compared to the adjacent normal tissue. Higher Hsp90 expression was observed in grade 2/3 IDCs (borderline association) and tumors of larger size. At the univariable analysis, higher Hsp90 expression was associated with higher ER Allred score, PR Allred score and c-erbB-2 positivity in IDC. Triple-negative IDCs exhibited significantly lower Hsp90 expression. The multivariable logistic regression model revealed that between the three markers, solely ER Allred score and c-erbB-2 positivity were independently associated with higher Hsp90 expression in IDC. CONCLUSION The above point to significant variability in Hsp90 expression with significant implications upon the effectiveness and limitations of anti-Hsp90 drugs.

Abstract
This study was designed to prospectively evaluate health-related quality of life in a homogeneous Mediterranean group of colorectal cancer patients. Ninety-five colorectal cancer patients were preoperatively assessed and followed-up with by skilled investigators using the Short Form-36 Health Survey questionnaire. Overall, patients showed deterioration in all domains, except for pain, when baseline values were compared with 3 and 6 months postoperatively ( P = 0.0001). A significant improvement of all Short Form-36 Health Survey questionnaire domains was noted between 6 and 12 months ( P = 0.0001). Scores for general health, pain, emotional well-being, and role limitations due to emotional problems at 1 year were shown better than preoperative ( P < 0.001). Improved scores in role limitations due to physical health and emotional problems were found at baseline and at 1 year, when laparoscopic were compared with open resections ( P < 0.05). Patients that received chemotherapy proved to be more vulnerable regarding their energy, social functioning, and role limitations at 3 months ( P < 0.05), whereas older patients had diminished physical functioning at 3 and 6 and 12 months ( P < 0.05) postoperatively. Greek colorectal cancer patients remain fragile up to 6 months after surgery, with significant improvements at 1 year, whereas certain aspects of health-related quality of life at 1 year may be even better than before surgery
