Abstract
Background/Aim Breast cancer is a complex disease with variability in clinical manifestation, response to current therapy, and biochemical and histological features among various subgroups. Histologic grading and immuno-histochemical evaluation of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2), and Ki-67 proliferation index play a crucial role in increasing the differential diagnostic value among various types of breast carcinoma. The aim of this study was to determine the histopathological and immuno-histochemical characteristics of breast tumors from a University Laboratory of Pathology in Greece. Patients and Methods The study included female patients over 18 years of age, whose histopathological and immunohistochemical reports were stored in the archives of the First Department of Pathology of National and Kapodistrian University of Athens. The study involved 197 female patients with a median age of 70 years and median tumor size of 2.6 cm. Results Most tumors were located at the left breast and ductal carcinoma was the most common histologic type (35.5%). Most tumors had histologic grade 2 (106, 53.8%), and were classified as TNM stage IIA (65, 33%). Most grade 1 and 2 tumors exhibited high expression of PR, whereas most grade 3 tumors had no PR expression. Moreover, patients with triple-negative cancer presented with grades 2 and 3 at a lower percentage compared to patients without a triple-negative phenotype (p=0.001). Conclusion The study provided valuable insights into the histopathological and immuno-histochemical characteristics involved in the development and progression of breast cancer.

Abstract
Translational perspective: Ischemic heart disease remains a major medical problem with high mortality rates. Beside the great efforts devoted to research worldwide and the use of numerous experimental models, an absolute understanding of myocardial infarction and tissue loss has not yet been achieved. Furthermore, the regeneration of myocardial tissue and the improvement of myocardial activity after ischemia is one of the major areas of interest in the medical (and especially cardiovascular) community. In a novel experimental rat model, the beneficial effect of mesenchymal stem cell transplantation (MSCT) in a surgically induced ischemic myocardium was documented. From a clinical perspective, this work supports the surgical administration of MSCT in the infarcted area during coronary artery bypass surgery. AIMS The regeneration of myocardial tissue and the improvement of myocardial activity after ischemia is one of the major areas of interest in cardiovascular research. We developed a novel experimental rat model and used it to examine the effect of mesenchymal stem cell transplantation (MSCT) on myocardial ischemia evaluated by SPECT-CT and immunohistochemistry. METHODS AND RESULTS An open thoracotomy took place for forty adult female Wistar rats with (n = 30) or without (n = 10) surgical ligation of the left anterior descending coronary artery (LAD) in order to cause myocardial ischemia. Myocardial viability was evaluated via SPECT/CT 7 days before surgery, as well as at 7 and 14 days post-surgery. At day 0, 15 animals received homologous stem cells injected at the ischemic myocardium area. A SPECT/CT evaluation showed decreased activity of the myocardial cells in the left ventricle one week post-infarction. Regeneration of the ischemic myocardium fifteen days post-infarction was recorded only in animals subjected to stem cell transplantation. These findings were also confirmed by histology and immunohistochemical analysis, with the significantly higher expression of GATA4 and Nkx2.5. CONCLUSIONS The positive effect of mesenchymal stem cell transplantation in the ischemic myocardium was recorded. The application of SPECT-CT allowed a clear evaluation of both the quality and quantity of the living myocardium post-infarction, leading to a new approach in the research of cardiovascular diseases. From a clinical perspective, MSCT may be beneficial when accompanied by myocardial revascularization procedures.

Abstract
OBJECTIVES In recent years, the local excision of benign rectal lesions or early-stage rectal cancers using minimally invasive surgical techniques has replaced radical interventions that caused impairment in patients' quality of life. The aim of the present study was to investigate the feasibility of transanal minimally invasive surgery (TAMIS), as well as its excision quality, its oncologic outcomes, and its impact on anorectal function. METHODS Patients who underwent TAMIS at a single colorectal unit of a tertiary university hospital from 2015 until 2020 for benign rectal lesions or early-stage malignant rectal lesions, along with unsuitable patients for radical interventions, were included in the present study. RESULTS Twenty-five patients underwent TAMIS for rectal lesions. Their median distance from the anal verge was 7 cm (range 4-12 cm) and their median size was 3.8 cm (range 2-6 cm). The median operative duration was 75 minutes (range 30-150 minutes) and the median hospitalization interval was 2 days (range 1-6 days). In addition, the negative resection rate was 100% and the recurrence rate was 4% during an average follow-up period of 30 months (range 3-36 months). Two patients (8%) presented short-term complications, and in 1 patient (4%) a hybrid technique was required. Seventeen patients (68%) reported moderate incontinence symptoms 6 weeks postoperatively that subsided in all patients 3 months postoperatively. CONCLUSIONS TAMIS seemed to be a feasible technique with adequate oncologic outcomes and high excision quality, which preserved patients' quality of life. The impact of TAMIS on anorectal function after neoadjuvant chemoradiotherapy for rectal cancer should be further investigated, however.

Abstract
BACKGROUND/AIM Myocardial infarction, an acute medical situation with a high mortality rate worldwide, has been extensively studied in modern cardiovascular research, using different experimental models. However, a deep understanding of myocardial activity loss has not been fully investigated. We have developed a novel experimental rat model for noninvasive assessment of myocardial ischemia based on single photon emission computed tomography (SPECT/CT), in order to further understand and evaluate myocardial activity before and after surgical induction of myocardial ischemia. MATERIALS AND METHODS Thirty adult female Wistar rats underwent open thoracotomy with (n=20) or without (n=10) surgical ligation of the left anterior descending coronary artery (LAD). The myocardial ischemia was confirmed with ECG and myocardial viability was evaluated via SPECT/CT at 7 days before as well as at 7 and 14 days post-surgery, after which animals were sacrificed and myocardial ischemic injury was further assessed histologically. RESULTS All animals were evaluated with anatomical and functional criteria based on the SPECT/CT imaging results. A successful surgical technique causing ischemia and loss of myocardial function in all animals undergoing a LAD ligation was established. Furthermore, evaluation of the viable myocardium with SPECT/CT confirmed the reduction of functional myocardial cells of the left ventricle post-infarction, which was also documented histologically. CONCLUSION Using our technique, the validity of this animal model to induce and evaluate myocardial ischemia was demonstrated. Our choice to apply SPECT-CT qualitative and quantitative evaluation of myocardial function leads to a new approach in experimentation with an anticipated significant impact in the ongoing cardiovascular laboratory research.

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
BACKGROUND/AIM U-74389G and ascorbic acid protect the cells from oxidation. This study aimed to depict their role in ischemia-reperfusion injury in a renal rat model. MATERIALS AND METHODS Sixty Wistars rats were randomized into six groups of 10 animals each. Group A Ischemia 30 min, reperfusion 60 min; Group B Ischemia 30 min, reperfusion 120 min; Group C Ischemia 30 min, ascorbic acid administration, reperfusion 60 min; Group D Ischemia 30 min, ascorbic acid administration, reperfusion 120 min; Group E Ischemia 30 min, U-74389G administration, reperfusion 60 min; Group F Ischemia 30 min, U-74389G administration, reperfusion 120 min. We then collected tissue and blood samples. RESULTS Histology and the significantly decreased malondialdehyde and tumor necrosis factor-α levels indicated that ascorbic acid was superior to U-74389G, at pre-defined time intervals. CONCLUSION Ascorbic acid and U-74389G ameliorated renal damage induced by ischemia-reperfusion injury, suggesting a therapeutic effect.

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
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
AIM To retrospectively assess the effectiveness and safety of BLES stereotactic biopsy of suspicious calcifications and investigate possible predictive factors for underestimation. METHODS AND MATERIALS Between January 2014 and January 2016, 400 biopsies of suspicious calcifications were performed in our Department using the BLES stereotactic device. The mean age of our population was 58.5 years (range 39-78 years). The final surgical results were used as gold standard. The effectiveness of the method was statistically evaluated. Mammographic size, grade, molecular type, and presence of comedo type/necrosis were assessed as predictive factors. RESULTS 90/400 (22.5%) cases were cancers (20% invasive cancers, 80% non-invasive cancers). 38/400 cases were atypical lesions (9.5%). No underestimation was found in atypical lesions that underwent surgery (29/38 cases). Downgrade was achieved in 45.5% of cases (with complete removal in 34.4%), concordance in 43.3%, and upgrade was found in 15.5% of the cases; the initial mammographic size and the grade of the cancers were found to be statistically significant predictive factors. The total complication rate was 8.75%. CONCLUSIONS Breast lesion excision system is a highly accurate and safe stereotactic biopsy technique of suspicious calcifications with low underestimations and high downgrade/removal rates with the potential to alter the final surgical decision in selected cases.

Abstract
Reactive oxygen species have a key role in liver ischemia-reperfusion (I/R) injury. In the present study, the effect of the anti-oxidant compound lazaroid U-74389G in preventing liver I/R injury was investigated in a swine model. Ischemia was produced by portal vein occlusion. Two sets of experiments were performed, each with two groups (n=7 per group). In the first group, the potential protective effect of an intracaval injection of U-74389G after a 30-min ischemia, followed by a 60-min reperfusion period was assessed (biopsies at 0, 15, 30 and 90 min experimental time). In the second set, the effect of intracaval U-74389G injection after 30 min of ischemia, followed by a longer reperfusion period of 120 min was determined (biopsies at 0, 15, 30 and 150 min experimental time). Liver malondialdehyde, hepatocyte vacuolation-degeneration, venous congestion, inflammatory cell infiltration, sinus congestion-dilation and Chiu score of intestinal damage were determined at up to 150 min of reperfusion. In the second set of experiments, the Chiu score of intestinal damage was improved by the administration of U-74389G (3.17±0.40 vs. 4.33±0.21; P=0.030). However, in the two sets of experiments, the liver inflammatory reaction was more pronounced in the U-74389G groups (P=0.017 for the first set, P=0.021 for the second set). No significant effect of U-74389G on any other parameters was detected. In conclusion, intestinal damage due to portal venous congestion and reflow appears to be mitigated by the lazaroid U-74389G; however, intracaval administration of U-74389G does not appear to exert any protective effects against liver I/R-induced inflammation.

Abstract
BACKGROUND The emphasis on aesthetic outcomes and quality of life after breast cancer surgery has motivated breast surgeons to develop oncoplastic breast conserving surgery (OPS). Training programs are still rare in most countries, and there is little standardization, which challenges the scientific evaluation of these techniques. This systematic review aims to assess oncological and cosmetic outcomes of OPS. METHODS After a strict selection process with precise inclusion and exclusion criteria, oncologic and aesthetic outcomes of oncoplastic surgery were searched, using the MEDLINE database up to September 30th, 2017. Available published literature was classified in levels of evidence. After a thorough screening process, only studies with the best level of evidence were included on selection. Systematic reviews and meta-analyses were not included for methodological reasons. RESULTS Titles and abstracts of 2.854 citations were identified and after screening 15 prospective studies including 1.391 patients were reviewed and scored in detail. Local relapse was found in 2.8% of cases with a wide range of follow-up (from 6 to 74 months). Close margins were retrieved in 11% of cases and positive margins in 9.4% of cases. Mastectomy was implemented in 6.9% of breast cancer patients to whom OPS was performed. Good cosmetic outcomes were detected in 90.2% of patients undergoing OPS, leaving open issues for who should perform cosmetic evaluation and which method should be used. CONCLUSION Tumor margins, mastectomy rates, and cosmetic outcomes of OPS have to be further improved by standardizing various aspects of OPS. Research efforts should focus on level I evidence assessing both oncological and aesthetic outcomes of OPS and survival rates.

Abstract
PURPOSE To assess the role of the breast lesion excision system (BLES) in complete removal of clusters of microcalcifications found on mammogram proved histologically to be high-risk lesions with cell atypia. METHODS AND MATERIALS Three hundred ninety-four consecutive women (mean age 58.5 years, range 39-78 years) with 400 clusters of suspicious microcalcifications underwent stereotactic biopsy using the intact BLES device between January 2014 and January 2016. All cases proved histologically to be high-risk lesions were subsequently assessed for complete removal. The underestimation rate was also assessed. RESULTS Thirty-eight out of 400 (9.5%) lesions were high-risk lesions with atypia with mean size 7.63 mm (st. dev. = 4.03 mm) which was within the size that the BLES needle can excise (20 mm). Four (10.5%) papillomas with atypia, 14 (36.8%) cases with flat epithelial atypia (FEA), 10 (26.3%) cases with lobular intraepithelial neoplasia (LIN-LIN 1, LIN 2), 8 (21.2%) with atypical ductal hyperplasia (ADH) and 2 (5.3%) cases with mucocele-like lesions (MLL) with atypia were found. Twenty-nine out of 38 lesions had subsequent surgery. Complete excision was achieved in 23/29 lesions (79.3%). No underestimation was found. Two-year mammographic stability was found in all lesions. Non-parametric statistical analysis showed no other significant predictive factor for complete excision apart from the distance of the lesions from the specimen margins (p = 0.031 Mann-Whitney test). CONCLUSION One-pass BLES intact biopsy technique is a safe method of complete removal of high-risk atypical lesions with high accuracy rates for certain histologies and could be potentially used as an alternative excision method to diagnostic surgery in selected cases. KEY POINTS • Breast lesion excision system (BLES) is an image-guided biopsy technique that uses radiofrequency to remove an intact piece of tissue including the target breast neoplasm. • Breast lesion excision system (BLES) under stereotactic guidance is able to accurately biopsy high-risk breast lesions expressed mammographically as clusters of suspicious microcalcifications. • BLES under stereotactic guidance is an accurate technique for en bloc excision of selected cases of small clusters of suspicious microcalcifications proved to be high-risk lesions with histopathologically disease-free margins of excision.

Abstract
PURPOSE RANKL, OPG and TRAIL have long been pursued in cancer. Mutated KRas proteins and c-Fos overexpression - well-recognized oncogenic events - have been conceived as coordinators of RANKL, OPG and TRAIL pathways. Considering the paucity in the relevant literature, the purpose of the present study was to investigate whether the expression of these molecules configures a distinct papillary thyroid carcinoma (PTC) subgroup with adverse clinicopathological characteristics. METHODS RANKL, OPG, TRAIL, KRas, and c-Fos immunohistochemical expression in relation to clinicopathological characteristics of PTC was assessed retrospectively in paraffin-embedded PTC specimens from 114 patients who underwent total thyroidectomy with simultaneous central lymph node dissection (CLND). RESULTS Expression of RANKL, OPG, TRAIL, Kras and c- Fos was revealed in 78.6, 63.2, 61.4, 47.4, and 73.7% of PTC, respectively. As predominant KRas-expressing PTC histotype emerged the classical PTC (cPTC), comprising 66.7% of PTC. A significant correlation was demonstrated of RANKL, OPG, and TRAIL expression with central lymph node metastasis CLNM (p=0.007, p<0.001, and p=0.002, respectively), concerning especially cPTC as regards to RANKL (p=0.027) and OPG (p=0.006), and both cPTC (p=0.043) and follicular variant of PTC (FVPTC) (p=0.049) with regard to TRAIL. OPG expression associated significantly with multifocality (p=0.045). Multivariable-adjusted logistic regression models characterized TRAIL as independent predictor of CLNM (OR=10.335, 95% CI: 1.23-86.87). CLNM correlated significantly with six pairs of coexpressions: TRAIL-KRas (p=0.011), TRAIL-c-Fos (p=0.006), OPG-c-Fos (p=0.024), RANKL-TRAIL (p<0.001), RANKL-OPG (p<0.001), TRAIL- OPG (p<0.001). CONCLUSION The present study suggested for the first time that OPG, RANKL, TRAIL expressions, either alone or in concert involving c-Fos and KRas expression, are related to CLNM. Further research is warranted to elucidate whether the examined molecules can be endorsed as indicators of aggressive PTC behavior and guide a personalized therapeutic intervention.

Abstract
BACKGROUND Adipose tissue contains variable amounts of stem cells that have recently attracted increased interest due to their strong proliferative and differentiation capacity. However, significant heterogeneity exists in terms of stem cell yield and viability profile among individuals as well as different donor areas. MATERIALS AND METHODS Between June 2016 and July 2016, forty (40) women underwent outpatient cosmetic liposuction procedures conferring a total of 53 lipoaspirates; inner thigh (n=13), outer thigh (n=9), abdomen (n=9), waist (n=16) and inner knee (n=6). Lipoaspirates were harvested using a tulip low-pressure syringe lipoaspiration system with a diameter of 3 mm. Centrifugation separated adipocytes from the stromal vascular fraction (SVF). Isolation of the adipose-derived stem cells (ASCs) was achieved through culture of the SVF. Viability of SVF cells and ASCs was evaluated with trypan blue dye under microscope and using flow cytometry with 7-AAD staining, respectively. Total cell count was estimated for both the SVF and ASCs. RESULTS Outer thigh exhibited significantly higher SVF cell count compared to any other donor site (p<0.05). In addition, inner and outer thigh showed a significantly higher number of ASCs compared to abdominal, waist, and inner knee samples (p<0.05). Finally, viability of SVF cells (range, 94-95%) and ASCs (range, 93.12-96.14%) was excellent with no significant differences among donor areas. CONCLUSION Tissue-harvesting area is a strong determinant of the quality of the fat grafts. Compared to abdomen, waist and inner knee, thighs seem favorable in terms of viability profile and yield of SVF cells and ASCs. Further randomized controlled trials incorporating a larger cohort of patients are warranted in order to verify our results.

Abstract
PURPOSE Vacuum Assisted Breast Biopsy (VABB) is a minimal invasive technique, in the diagnostic approach for non palpable lesions. The aim of this study was to evaluate the efficacy and accuracy of VABB in the investigation of breast microcalcifications, a significant mammographic sign of early breast cancer. The rate of histological underestimation and the false negative rate were assessed based on the follow up data and the histological examination of the surgical specimens. METHODS From January 2005 to November 2011, 853 women with mammographically detected microcalcifications, classified as BI-RADS 3-5, were referred to our Breast Unit for evaluation. During this 6-year period, 825 vacuum-assisted breast biopsies were performed, while 28 women (3.3%) were not submitted to VABB due to superficial location of microcalcifications. RESULTS VABB histology revealed 594 benign (69.6%), 66 high risk (7.7%) and 164 malignant (19.2%) lesions. Twenty- nine cases were classified as non diagnostic, as in one case (0.1%) the sample of the biopsy was maladjusted and not suitable to undergo histopathological examination due to mechanical alterations and in 28 (3.3%) cases microcalcifications were located in proximity to the skin and open surgical excision was performed. The overall documented underestimation rate was 4.6%, the false negative rate was 2.4%. The sensitivity of the method was 98.2%, specificity 100%, positive predictive value 100% and negative predictive value 97.6%. CONCLUSIONS VABB is a safe and accurate method for the evaluation of suspicious microcalcifications and diagnosis of early breast cancer.

Abstract
A multi-wavelength prism coupling refractometer is utilized to measure the angular reflectance of freshly excised human intestinal tissue specimens. Based on reflectance data, the real and imaginary part of the refractive index is calculated via Fresnel analysis for three visible (blue, green, red) and two near-infrared (963 nm and 1551 nm) wavelengths. Averaged values of the complex refractive index and corresponding Cauchy dispersion fits are given for the mucosa, submucosa and serosa layers of the colorectal wall at the normal state. The refractive constants of tumorous and normal mucosa are then cross-compared for the indicative cases of one patient diagnosed with a benign polyp and three patients diagnosed with adenocarcinomas of different phenotype. Significant index contrast exists between the normal and diseased states, indicating the potential use of refractive index as a marker of colorectal dysplasia.

Abstract
The refractive index is an optical constant that plays a significant role in the description of light-matter interactions. When it comes to biological media, refraction is understudied despite recent advances in the field of bio-optics. In the present article, we report on the measurement of the refractive properties of freshly excised healthy and cancerous human liver samples, by use of a prism-coupling technique covering the visible and near-infrared spectral range. Novel data on the wavelength-dependent complex refractive index of human liver tissues are presented. The magnitude of the real and imaginary part of the refractive index is correlated with hepatic pathology. Notably, the real index contrast is pointed out as a marker of discrimination between normal liver tissue and hepatic metastases. In view of the current progress in optical biosensor technologies, our findings may be exploited for the development of novel surgical and endoscopic tools.

Abstract
Aromatase inhibitors (AIs) are widely used as adjuvant hormonal therapy in postmenopausal women with hormone receptor-positive breast cancer. The purpose of this study was to investigate the potential impact of AIs on the anterior segment of the eye and especially the ocular surface. Participants in our study were 41 hormone receptor-positive early stage breast cancer patients (80 eyes), treated with AIs, while 80 eyes of 40 age- and gender-matched healthy controls, not previously used AIs for any purpose, were also evaluated. All participants underwent a complete ophthalmological examination, including best corrected visual acuity (BCVA) assessment, slit-lamp biomicroscopy, and dilated fundus examination. Ocular surface disease-related symptoms and signs were also recorded. The most common symptom was found to be blurred vision, while other symptoms included foreign body sensation, tearing, redness, and photophobia. Slit-lamp examination revealed blepharitis and meibomian gland dysfunction in 75% and 42.5% of patients, respectively. Superficial punctate keratitis and conjunctival injection were also present. Our results demonstrated a high prevalence of ocular surface disease-related symptoms and signs in patients receiving AIs compared to healthy controls. This study may raise a flag regarding the use of AIs. However, further and larger prospective longitudinal studies are needed to examine the possible effect of AIs alone or in combination with chemotherapy in the eyes of breast cancer patients.

Abstract
The physiological and pathological development of the breast is strongly affected by the hormonal milieu consisting of steroid hormones. Mass spectrometry (MS) technologies of high sensitivity and specificity enable the quantification of androgens and consequently the characterization of the hormonal status. The aim of this study is the assessment of plasma androgens and androgen glucuronides, in the par excellence hormone-sensitive tissue of the breast, through the application of liquid chromatography-mass spectrometry (LC-MS). A simple and efficient fit-for-purpose method for the simultaneous identification and quantification of dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4), androsterone glucuronide (ADTG) and androstane-3α, 17β-diol-17-glucuronide (3α-diol-17G) in human plasma was developed and validated. The presented method permits omission of derivatization, requires a single solid-phase extraction procedure and the chromatographic separation can be achieved on a single C18 analytical column, for all four analytes. The validated method was successfully applied for the analysis of 191 human plasma samples from postmenopausal women with benign breast disease (BBD), lobular neoplasia (LN), ductal carcinoma in situ and invasive ductal carcinoma (IDC). DHEAS plasma levels exhibited significant differences between LN, IDC and BBD patients (P < 0.05). Additionally, ADTG levels were significantly higher in patients with LN compared with those with BBD (P < 0.05).

Abstract
From the available literature, it is unclear what proportion of pancreatic adenocarcinomas express estrogen receptors (ERα, ERβ), progesterone receptors (PR), and androgen receptors (AR), and if any of these markers have prognostic significance. We aimed to assess (1) the expression and (2) the correlation of the aforementioned markers with clinicopathological parameters and prognosis in patients with pancreatic adenocarcinoma. During a five-year period, 60 patients with pancreatic ductal adenocarcinoma underwent surgical resection at a single institution. Immunohistochemical stains of the studied markers were quantified by Image analysis system. ERα expression was positively associated with PR expression. Moreover, ERβ was inversely associated with the presence of metastases, whereas no significant associations implicated AR. As far as the prognostic significance of the studied receptors is concerned, higher ERα expression correlated with poorer survival at the univariate analysis, but the finding dissipated at the multivariate approach. No significant associations with overall survival were noted regarding the other receptors. The role of sex hormone receptors in the survival from pancreatic adenocarcinoma seems rather limited. Further prospective studies assessing those receptors should ideally be designed in order to confirm our results and possibly outline additional correlations between other steroid receptors and features of pancreatic adenocarcinoma.

Abstract
As surgeons became more adept with laparoscopic colon surgery, other less invasive procedures, such as single-incision laparoscopic right hemi-colectomy (SIL-RH), have been applied. The objective of this study was to evaluate the safety of SIL-RH as well as its intraoperative and postoperative outcomes for right-sided colon diseases. A detailed search in PubMed for citations that included SIL-RH from 2000 to 2014 revealed 21 studies fulfilling the criteria of the present review. A total of 684 patients were analyzed. Of the patients, 50.2 % were men. Mean patient age was 64.8 years. Of the patients, 36.1 % had already undergone an abdominal operation before the performance of SIL-RH, while 69 % of the patients underwent SIL-RH for colon cancer. Relatively low rates of overall morbidity (15 %) and mortality (0.75 %) were reported in the included studies. Mean length of postoperative hospital stay (LOS) was 5.5 days. Bowel motility return had a mean value of 2.8 days. Mean number of harvested lymph nodes (LN) was 19.2 LN. All resection margins were tumor-free. SIL-RH was a safe alternative to multiport laparoscopic right hemi-colectomy (ML-RH) in terms of morbidity and mortality, postoperative gastrointestinal function recovery, LOS, as well as oncological radicalness.

Abstract
PURPOSE Acetaminophen-induced liver injury (APAP) is recognized as a frequent etiologic factor responsible for hepatic damage in the developed world. Management remains still elusive as treatment options are limited and their results are inconclusive. Consequently new strategies are explored at the experimental level. Mesenchymal stem cells (MSCs) present a promising modality as they can promote liver regeneration (LG) and compensate acute liver injury (ALI). MATERIALS AND METHODS Our research was focused on articles related to drug-induced liver injury, mechanisms of liver regeneration (LG) after Acute Liver Injury (ALI) and recent experimental protocols of Mesenchymal Stem Cells (MSCs) transplantation after chemical insult. All these studies are cited on Pubmed and MedLine. RESULTS This review has three distinct sections. First recent developments in ALI pathogenesis are presented. The second section covers cellular pathways and histological findings relevant to liver regeneration. The final chapter analyzes MSCs transplantation protocols after ALI and interrelation between liver regeneration and hepatic differentiation of MSCs. CONCLUSION Adipose tissue stem cells (ADSCs) and (MSCs) transplantation represents a promising modality in severe ALI management although many aspects remain to be clarified.

Abstract
An ever growing number of medical organizations, societies, working groups and governmental agencies issue algorithms i.e. guidelines, of decision making flowcharts in diagnosis and treatment in a variety of diseases. In the field of evidence-based diagnosis and treatment of breast cancer, a large number of guidelines are available both from medical associations and national health departments. Among the most appreciated and utilized comprehensive guides is the European Society for Medical Oncology (ESMO) Breast Cancer Guidelines and from the other side of the Atlantic the National Comprehensive Cancer Network (NCCN) Guidelines in Breast Cancer. Although there is much concordance between the guidelines from these two organizations, it is intriguing to locate their discrepancies also. The aim of this report is to present a number of different points between ESMO and NCCN in the whole spectrum of breast cancer management, from prevention and diagnosis to treatment and follow up. This systematic review was performed in accordance with the PRISMA guidelines using a predefined search strategy and summarizes in detail, the differences between ESMO and NCCN guidelines regarding genetic risk evaluation and screening, surgery, chemotherapy, endocrine treatment, targeted biological agents, radiotherapy, pregnancy and fertility and follow-up.

Abstract
AIM The objectives of our explorative study were to (i) evaluate the immunohistochemical expression of sex steroid hormone receptors (estrogen receptor a [ERα], estrogen receptor β [ERβ], progesterone receptor [PR] and androgen receptor [AR]), angiogenesis factors (vascular endothelial growth factor [VEGF] and inhibitor of differentiation/DNA synthesis 1 [Id-1]) and cell-cycle regulators (cyclin D1, p16 and p27) in intraductal papillary mucinous neoplasms (IPMNs) in comparison to normal adjacent pancreatic tissues and (ii) assess their correlation with the grade and histological sub-type of those lesions. MATERIALS AND METHODS Paraffin-embedded specimens from 12 consecutive patients with IPMNs were immunostained for the studied markers and staining quantification was assessed by an image analysis system. RESULTS AR H-score and cyclin D1 H-score were significantly higher in the IPMN lesions (0.86±0.33 vs. 0.57±0.12 in the normal tissue, p=0.010 and 0.47±0.23 vs. 0.21±0.20 in the normal tissue, p=0.019, respectively). No significant differences were noted regarding the expression of ERα, ERβ, PR, p16, p27, VEGF, Id-1 or MVD. Moreover, no significant associations were found between the expression of studied markers and grade or histological subtype. CONCLUSION Our study showed higher expression of AR and cyclin D1 in IPMNs compared to normal pancreatic ducts without any association between AR and cyclin D1 expression and IPMNs' grade or subtype.

Abstract
BACKGROUND/AIM It is well-known that inflammatory bowel disease (IBD) poses an increased, yet not definitely estimated, risk of colitis-associated colon cancer (CAC), which is considered a more aggressive and distinct in both genetic and molecular levels clinical entity compared to sporadic colorectal cancer (CRC). The present review discusses the cytokine networks involved in CAC-based translational findings from suitable animal models of the disease. Moreover, we summarize the most prominent data concerning the role of Th1, Th2, Th17 and anti-inflammatory cytokines in the pathogenesis of CAC. Last, we briefly address the controversies between basic science findings in IBD and CAC and suggest further directions regarding research on cytokines. This review should serve as a primer for clinicians and surgeons to understand the rapidly evolving field of cytokines in the context of CAC. MATERIALS AND METHODS The MEDLINE database was thoroughly searched using the keywords: cytokines, colitis-associated cancer, animal models, carcinogenesis. Additional articles were gathered and evaluated.

Abstract
The prognostic significance of cyclin D1, p16(INK) (4A) and p27(Kip1) expression has been documented in several human malignancies; however, their prognostic potential in pancreatic adenocarcinoma is still unclear. This study aimed to assess the correlation of the aforementioned molecules with clinicopathological parameters and prognosis. Sixty patients with pancreatic ductal adenocarcinoma underwent surgical resection at a single institution; immunohistochemical staining of the studied markers was quantified by Ιmage analysis system. Cyclin D1 overexpression was positively associated with grade, neural infiltration and vascular invasion, whereas p27 positively correlated with age. Higher cyclin D1 expression indicated poorer survival (adjusted HR = 9.75, 95%CI: 1.48-64.31, p = 0.018, increment: one unit in H-score), whereas a marginal trend toward an association between p16 positivity and improved survival was observed (adjusted HR = 0.58, 95%CI: 0.32-1.05, p = 0.072 regarding positive vs negative cases). No significant association with overall survival was noted regarding p27. In conclusion, cyclin D1 overexpression and possibly p16 loss of expression in pancreatic adenocarcinoma seem to be adverse prognostic factors, whereas p27 expression did not seem to possess such prognostic properties. Further validation of the present findings in studies encompassing larger samples seems to be needed.

Abstract
AIM The mesenchymal-epithelial transition factor (MET) is a receptor tyrosine kinase that plays a key role in cell survival, growth, angiogenesis and metastasis. Because its expression is frequently altered in tumors, MET is currently under investigation as a potential target for anticancer therapy. The purpose of the present study was to determine the prognostic value of tumor MET expression levels in patients with estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-positive breast cancer, in order to strengthen the rationale for targeted therapy using MET inhibitors in this breast cancer subpopulation. MATERIALS AND METHODS We determined the expression of MET in formalin-fixed paraffin-embedded surgical specimens of ER- and HER2-positive breast cancer by immunohistochemistry. RESULTS Comparisons of MET expression with clinical parameters, including survival of the patients, were performed with MET expression as a dichotomized variable classified as high or low. Out of 78 tumors, 3 (3.8%) showed high MET expression. The analysis examining the association between MET and survival did not yield any statistically significant result regarding overall survival or disease-free survival. CONCLUSION ER- and HER2-positive breast carcinomas do not exhibit high MET expression. This null finding, the first to be reported in the literature, is of great importance, since it indicates that this sub-group population is not proper candidate for clinical trials with MET inhibitors.

Abstract
BACKGROUND Significant controversy exists in the literature regarding the role of pregnancy in the prognosis of breast cancer. We designed a matched case-case study, matching pregnancy-associated breast cancer (PABC) cases with breast cancer cases for stage, age, and year of diagnosis. PATIENTS AND METHODS 39 consecutive cases of PABC were matched with 39 premenopausal cases of breast cancer. Univariate and multivariate survival analyses followed by adjustment for stage, grade, estrogen receptor status, and age at diagnosis, were performed. RESULTS Regarding overall survival (OS), univariate analysis pointed to longer OS in non-PABC cases vs. PABC cases. Accordingly, a more advanced stage predicted shorter survival. In the multivariate analysis, the independent aggravating effect mediated by pregnancy persisted. Interestingly, a post hoc nested analysis within PABC cases indicated that the 3rd trimester pointed to shorter OS. The aforementioned results on OS were also replicated during the examination of relapse-free survival. CONCLUSION Implementing a matched case-case design, the present study points to pregnancy as a poor prognostic factor for breast cancer.

Abstract
This case control study aims to investigate the role of MMP-2 -1306C>T polymorphism as a potential risk factor and possible prognostic marker for breast cancer in a South European population. 113 consecutive incident cases of histologically confirmed ductal breast cancer and 124 healthy controls were recruited. MMP-2 -1306C>T polymorphism was genotyped; multivariate logistic regression as well as Cox regression analysis were performed. MMP-2 -1306C>T status was not associated with breast cancer risk either at the total sample or at the subanalyses on premenopausal and postmenopausal women. At the survival analysis, a trend towards a favorable association between MMP-2 -1306C>T allele and disease-free survival as well as overall survival was observed. Regarding subanalyses on ER-negative and ER-positive cases, the favorable association implicating MMP-2 -1306C>T allele was particularly evident among ER-positive cases; no significant associations emerged among ER-negative cases. MMP-2 -1306C>T polymorphism does not seem to be a risk factor for breast cancer in South European population; however, a trend towards a favorable association with survival has been observed.

Abstract
PURPOSE Contradictory results have been reported concerning the role of maspin and its cellular distribution in breast cancer. The purpose of this study was to examine the subcellular localization (nuclear-cytoplasmic) of maspin in breast cancer and to compare the evaluation of maspin immunostaining via light microscopy (LM) to the estimation via computerized image analysis (CIA) system. We also examined correlations between maspin expression and several clinicopathological parameters. METHODS The sample consisted of 48 primary invasive ductal carcinomas (IDC) of the breast. Maspin immunostaining was quantified and graded via LM by two pathologists, separately in the nuclear and cytoplasmic compartments. Total maspin expression was also estimated via CIA system. Univariate non-parametric statistics and stepwise multivariate ordinal logistic regression were performed. RESULTS Both maspin components (nuclear and cytoplasmic) were closely associated with each other (p<0.001). Total maspin score was positively and closely associated with nuclear maspin (p<0.001) and cytoplasmic maspin (p<0.001). Total maspin , nuclear maspin and cytoplasmic maspin did not correlate significantly with either age, grade, T, N and M status, stage, micro vessel density (MVD) (CD34), ki-67, p53, estrogen receptor (ER) and HER-2 status, or with any of the 4 groups of the molecular classification. The only factor that showed a borderline inverse correlation with nuclear maspin (p=0.059) was progesterone receptors (PR) positivity. CONCLUSION The cytoplasmic and nuclear fractions of maspin seem to be closely interwoven. Evidently, both mutually intertwined counterparts were independently reflected upon the total maspin levels measured by CIA. Future studies should ideally encompass all three approaches (nuclear, cytoplasmic, total) adopted herein.

Abstract
BACKGROUND Stereotactic vacuum assisted breast biopsy (VABB) procedures remain of key importance in the diagnostic evaluation of suspicious non-palpable mammographic lesions. The Breast Lesion Excision System(®) (BLES) is an image-guided percutaneous biopsy method that utilizes radiofrequency (RF) in order to retrieve an intact-tissue biopsy specimen. The purpose of this study is to determine the effects of RF application on the tissue specimen and the possible interference with the histopathologic results. METHODS In this study we included 265 patients with suspicious non-palpable mammographic lesions who underwent 273 stereotactic VABB procedures using the BLES. All biopsies were performed by the same surgical-radiology team under local anesthesia. The specimen thermal damage was classified according to the pathology report in 3 categories: Severe (extensive thermal damage or inability to diagnose), medium (ability to diagnose but either circumferential damage >1.5 mm or diffuse areas of thermal damage) and mild (circumferential thermal damage <1.5 mm but >0.5 mm). RESULTS Radiofrequency-associated thermal damage of the specimen was observed in 14 cases (5.13 %), and was classified as severe in 5, medium in 5, and mild in 4 specimens. Within the group of RF damaged specimens, we found a significant (p < 0.05) positive correlation between fat cell content and classification of thermal damage. CONCLUSIONS Although thermal damage is of concern during BLES breast biopsy, the incidence is low, and the outcome of the histopathologic assessment is not affected even in severely damaged specimens. Increased thermal damage seems to correlate with higher fat cell content of the specimen.

Abstract
The main indication of prophylactic mastectomy pertains to BRCA1 or BRCA2 mutation carriers. Prophylactic mastectomy includes the simple method and the subcutaneous method. Both methods can be followed by breast plastic reconstruction either at the same time or later. This review examines key issues regarding prophylactic mastectomy: the selection of patients, its effectiveness, its limitations, convergence/divergence in existing guidelines, and future perspectives.

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.
