In addition, this review underscores the prognostic significance of specific mutations, such as loss of TP53, and explores some potential targeted therapies tailored to these molecular signatures. The findings highlight the importance of genomic analyses for risk assessment, early detection and the design of personalized treatment approaches in pancreatic cancer. Overall, this review provides a comprehensive analysis of the molecular intricacies of pancreatic tumors, paving the way for more effective and tailored therapeutic interventions.

Exosomes in breast cancer management: Where do we stand? A literature review.

BACKGROUND: Exosomes constitute cellular molecular fingertips that participate in intercellular communication both in health and disease states. Hence, exosomes emerge as critical mediators of cancer development and progression, as well as potential biomarkers and novel therapeutic targets. OBJECTIVE: To review literature data regarding applications of circulating exosomes in breast cancer management. METHODS: This is a literature review of relevant published studies until April 2020 in PubMed and Google Scholar databases. Original papers in the English language concerning exosome related studies were included. RESULTS: Exosomes represent molecular miniatures of their parent cells. Several homeostatic mechanisms control exosomal secretion and synthesis. Exosomal exchange among cells creates an intricate intercellular crosstalk orchestrating almost every tissue process, as well as carcinogenesis. Available data highlight exosomes as major mediators of cancer development and progression. The secretion of specific exosomal molecules, particularly miRNAs, correlates with the underlying processes and can be used as a means of tumor detection and prognostic assessment. CONCLUSIONS: Exosomal miRNAs expression profiles and levels closely relate to cancer extent, type and prognosis. Deep comprehension of such correlations and systematization of experimental outcomes will offer a novel approach in cancer detection and management.

The Hellenic Emergency Laparotomy Study (HELAS): A Prospective Multicentre Study on the Outcomes of Emergency Laparotomy in Greece.

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.

Complex refractive index of freshly excised human breast tissue as a marker of disease.

We report differences in the refractive index of healthy and tumorous freshly excised human breast tissue as determined from reflectance profile measurements at five wavelengths (432 nm, 532 nm, 633 nm, 964 nm, 1551 nm) in the visible and near-infrared using a standard prism-coupling refractometer. These refractive index differences, particularly in the near-infrared, can be used to distinguish fibroadenomas and cancerous growths not only from normal breast tissue but also from each other.

A novel way of hook wire placement for surgical resection of suspicious breast lesions using the stereotactic vacuum assisted breast biopsy table.

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.

Mega-megacolon: a case report.

PURPOSE: Large bowel obstruction and megacolon formation secondary to complicated diverticulitis is rare. METHODS: We present a case of an 84-year-old woman surviving large bowel obstruction and mega-megacolon formation secondary to complicated diverticulitis, with an impressive presentation of abdominal distention. RESULTS: The patient's symptoms, laboratory test results, and imaging were consistent with large bowel obstruction. The patient underwent urgent exploratory laparotomy. Upon entry in the abdomen, it was unexpected that the extreme colonic wall thickening had prevented perforation, indicating the longtime course of illness. The biopsy of the specimen from the site of the obstruction demonstrated an inflammatory obstructing mass. CONCLUSION: This report aims to point out the atypical and in-extremes presentation of an otherwise common disease.

Thyroid nodules as a risk factor for thyroid cancer in patients with Graves' disease: A systematic review and meta-analysis of observational studies in surgically treated patients.

OBJECTIVE: Graves' disease (GD) is an autoimmune thyroid disorder characterized by hyperthyroidism. The incidence of thyroid cancer in patients with GD varies from 0.15% to 15%. There is conflicting evidence on the role of thyroid nodules as a risk factor for thyroid cancer in patients with GD. DESIGN: Three electronic databases (PubMed, Cochrane Library, Scopus) as well as grey literature sources were searched, from inception until 25 February 2019, for observational studies about the prevalence of thyroid cancer in patients with GD. PATIENTS: Clinical and ultrasonographic examination was necessary preoperatively for all patients to be classified depending on the presence/absence of thyroid nodules. MEASUREMENTS: Primary outcome was the incidence of thyroid cancer. The latter was determined after total or near-total thyroidectomy by the histopathologic report. Statistical analysis was performed with revman 5.3 software. RESULTS: The systematic review and meta-analysis included 7 studies with 2582 patients overall. The prevalence of any thyroid cancer was 11.5%. The presence of at least one thyroid nodule in patients with GD was associated with higher risk for thyroid cancer (odds ratio [OR] 5.3, 95% confidence interval [CI] 2.4-11.6, I2 83%). A subgroup analysis showed no difference in thyroid cancer risk in patients with GD according to the number of nodules (solitary versus multiple) (OR 1.4, 95% CI 0.9-2.3, I2 0%). CONCLUSIONS: The presence of thyroid nodules is positively associated with the prevalence of thyroid cancer in surgically treated patients with GD. However, further prospective research is needed as the heterogeneity among the studies is high.

Inhaled Cisplatin for NSCLC: Facts and Results.

Although we have new diagnostic tools for non-small cell lung cancer, diagnosis is still made in advanced stages of the disease. However, novel treatments are being introduced in the market and new ones are being developed. Targeted therapies and immunotherapy have brought about a bloom in the treatment of non-small cell lung cancer. Still we have to find ways to administer drugs in a more efficient and safe method. In the current review, we will focus on the administration of inhaled cisplatin based on published data.

Genes' Interactions: A Major Contributor to the Malignant Transformation of Endometriosis.

The genetic and epigenetic factors that contribute to the malignant transformation of endometriosis are still under investigation. The objective of the present study was to investigate the genetic link between endometriosis and cancer by examining and correlating the latest clinical observations with biological experimental data. We collected updated evidence about the genetic relationship between endometriosis and cancers by conducting a comprehensive search of PubMed and Scopus databases, focusing on the papers published between January 2018 and January 2019. New insights into the mechanism of the malignant transformation of endometriosis have been published recently. The use of state-of-the-art techniques and methods, such as the genome-wide association study analysis and the weighted gene co-expression analysis, have significantly altered our understanding of the association between endometriosis and endometriosis-associated cancer development. Interestingly, the interactions formed between genes seem to play a pivotal role in the phenotypic expression of mutations. Therefore, the effect of single nucleotide polymorphisms and the function of the expression quantitative trait loci on genes' expression have been the subject of many recent works. In addition, it has been discovered that genes, the mutations of which have been related to the development of endometriosis, play a role as hub genes. This may lead to new areas of research for understanding the mechanism of malignant transformation of the disease. Significant steps forward have been made towards the identification of factors that control the malignant transformation of endometriosis. Still, due to rarity of the event, a better-organized scheme for sampling on a global level should be adopted.

Comparison between Magnification Techniques and Direct Vision in Thyroid Surgery: A Systematic Review and Meta-Analysis.

Background and Objectives: The most common complications after conventional thyroid surgery in adult patients are recurrent laryngeal nerve (RLN) injury and hypocalcemia. Magnification techniques (surgical loupes or surgical microscope) are used for identification of RLN and parathyroid glands to diminish these complications although more evidence is necessary to assess their safety and efficacy in comparison with direct vision. Methods and Materials: Electronic databases (Pubmed, Cochrane Library, Scopus) as well as gray literature sources were searched for randomized controlled trials (RCTs) comparing the frequency of transient/permanent RLN injury and hypocalcemia after thyroid surgery by using magnification techniques and direct vision for identification of RLN and parathyroid glands until October 17, 2019. The main outcomes were transient/permanent RLN injury and hypocalcemia. For all outcomes, 95% confidence intervals (95% CI) were used. Statistical analysis was performed with RevMan 5.3. Results: Systematic review and meta-analysis included 3 RCTs with 437 patients overall. Magnification techniques did not significantly affect the risk of occurrence of transient RLN injury (OR = 0.38, 95% CI (0.11-1.35), I2 = 0%) and transient hypocalcemia (OR = 0.31, 95% CI (0.09-1.09), I2 = 23%) compared with direct vision. Included RCTs demonstrated only two patients with permanent hypocalcemia and another one with permanent RLN injury, who belonged to the direct vision group. Conclusion: The use of magnification techniques for identification of RLN and parathyroid glands seems to be as safe as direct vision. However, they do not decrease the risk of RLN injury and transient hypocalcemia after thyroid surgery compared with direct vision. Finally, further prospective research should be conducted as the sample among the studies was small.

Pharmacologic and Non-Pharmacologic Interventions for HIV-Neuropathy Pain. A Systematic Review and a Meta-Analysis.

Background and Objectives: Among HIV infection symptoms, sensory neuropathy (HIV-SN) remains a main cause of suffering, with incidence varying from 13-50%. So far, numerous pharmacological and non-pharmacological treatments have been tested, although few evidence-based analgesic options are available. We conducted an up-to-date systematic review and meta-analysis of the literature in order to evaluate the efficacy and safety of pharmacologic and non-pharmacologic treatments for pain control, in patients with HIV neuropathy. Materials and Methods: We searched MEDLINE, EMBASE, Scopus/Elsevier, The Cochrane Central Register of Controlled Trials (CENTRAL), USA Clinical Trials registry, and The International Web of Science up to April 2019. All randomized controlled trials evaluating efficacy and safety of non-pharmacologic and pharmacologic therapies were included. Efficacy was defined as pain reduction during the study period. Safety was estimated from adverse events. A meta-analysis was performed whenever possible. Results: 27 randomized controlled trials (RCTs) were included for analysis (7 evaluating non pharmacologic interventions, 20 pharmacologic therapies). Non-pharmacologic studies (n = 742) involved seven different therapeutic modalities. Only Acupuncture/Moxibustion showed pain reduction over placebo, Gracely Pain Scale Mean (SD): Acu/Moxa 0.85 (0.12), placebo 1.10 (0.09), p = 0.05. Pharmacologic studies, involving 2516 patients revealed efficacy for capsaicin 8% over placebo (mean difference -8.04 [95% CI: -14.92 -1.15], smoked cannabis (where pooling data for meta-analysis was not possible) and recombinant Nerve Growth Factor. Conclusion: Despite various modalities for pain control in HIV-SN, strongest evidence exists for capsaicin 8% and smoked cannabis, although of low methodological quality. Among non-pharmacologic modalities, only Acu/Moxa gave a marginal beneficial effect in one study, possibly limited by inherent methodological flaws.

Comparison of Laryngoscopic Views betweenC-MAC™ and Conventional Laryngoscopy in Patients with Multiple Preoperative Prognostic Criteria of Difficult Intubation. An Observational Cross-Sectional Study.

Background and Objectives: Video laryngoscopy has been proven useful under difficult airway scenarios, but it is unclear whether anticipated improvement of visualization is related to specific difficult intubation prognostic factors. The present study evaluated the change in laryngoscopic view between conventional and C-MAC® laryngoscopy and the presence of multiple difficult intubation risk factors. Materials and Methods: Patients scheduled for elective surgery with >2 difficult intubation factors, (Mallampati, thyromental distance (TMD), interinscisor gap, buck teeth, upper lip bite test, cervical motility, body mass index (BMI)) were eligible. Patients underwent direct laryngoscopy (DL) followed by C-MAC™ laryngoscopy (VL) and intubation. Change of view between DL and VL, time for best view, intubation difficulty scale (IDS) and correlation between prognostic factors, laryngoscopic view improvement, and IDS were measured. Results: One-hundred and seventy-six patients completed the study. VL lead to fewer Cormarck-Lehane (C/L) III-IV, compared to DL (13.6% versus 54.6%, p < 0.001). The time to best view was also shorter (VL: 10.82 s, DL: 12.08 s, p = 0.19). Mallampati III-IV and TMD ≤ 6 cm were related to improvement of C/L between DL and VL. Logistic regression showed these two factors to be a significant risk factor of the glottis view change (p = 0.006, AUC-ROC = 0.57, 95% CI: 0.47-0.66). 175/176 patients were intubated with VL. 108/176 were graded as 0 < IDS ≤ 5 and 12/176 as IDS > 5. IDS was only correlated to the VL view (p < 0.0001). Conclusion: VL improved laryngoscopic view in patients with multiple factors of difficult intubation. Mallampati and TMD were related to the improved view. However, intubation difficulty was only related to the VL view and not to prognostic factors.

The value of stereotactic vacuum assisted breast biopsy in the investigation of microcalcifications. A six-year experience with 853 patients.

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.

Efficacy of esophageal stents as a primary therapeutic option in spontaneous esophageal perforations: a systematic review and meta-analysis of observational studies.

Background: Spontaneous esophageal perforation traditionally mandates urgent surgical treatment. Lately, esophageal stents have been used to reduce the associated morbidity and mortality. The current systematic review aimed to assess the efficacy of stents as a primary treatment option in this scenario. Methods: A systematic search was conducted in PubMed/MEDLINE, Scopus and the Cochrane Library for studies published in the English language between 2000 and 2023. We included observational studies reporting on the use of stents, alongside conservative measures and drainage procedures, in patients with spontaneous esophageal perforations. Primary outcomes were sealing rate (persistent leak occlusion) and failure rate (mortality or conversion to a major surgical operation). Secondary outcomes included patients' presentation, sepsis, drainage procedures, and reinterventions. Results for primary outcomes were presented as pooled rates with 95% confidence intervals (CIs), using a random-effects model. Methodological quality was assessed using the MINORS score. Results: Eighteen studies involving 171 patients were included. Sealing rate was 86% (95%CI 77-93%) and failure rate was 14% (95%CI 7-22%). Weighted mortality rate was 6% (95%CI 2-13%), while conversion to surgical treatment was 2% (95%CI 0-9%). Late presentation was not related to a statistically significant increase in treatment failure (odds ratio 1.85, 95%CI 0.37-9.30; P=0.72). Drainage procedures were required for the majority of patients, with a high rate of surgical and endoscopic reinterventions. Conclusions: Our results imply that stents may offer an effective and safe alternative treatment for patients with spontaneous esophageal perforations. Additional endoscopic and surgical drainage procedures are frequently needed.

Dysbiosis Signature of Fecal Microbiota in Patients with Pancreatic Adenocarcinoma and Pancreatic Intraductal Papillary Mucinous Neoplasms.

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.

The Role of Serum Nestin in Diagnosis and Prognosis of Breast Cancer: A Prospective Observational Study.

BACKGROUND/AIM: The molecular classification of breast cancer has enabled targeted therapy for specific molecular subtypes. Nestin, which has been studied for its role in oncogenesis, could contribute to this direction. This study aimed to investigate the differences between serum nestin levels and molecular profiling, as well as histopathological tumor types, in women who underwent surgery for breast cancer. PATIENTS AND METHODS: Women who underwent surgery for breast cancer at the Breast Unit of the 1st Propaedeutic Department of Surgery, Hippocration General Hospital, National and Kapodistrian University of Athens were prospectively included. Patients' demographic data were recorded and serum nestin levels were measured. Molecular biomarker analysis was performed, as well as histopathologic assessment. RESULTS: Seventy patients were included in the analysis. Among patients with breast cancer, 93% were estrogen receptor (ER) positive, 91% were progesterone receptor (PR) positive, and 43% were human epidermal growth factor receptor 2 (HER2) positive. Ki67 was expressed in 16% of patients and p53 was expressed in 32% of patients. Invasive ductal carcinoma was diagnosed in 80% of patients, with 44% of tumors classified as T1 and 46% as T2. Additionally, 43% were G1 and 56% were N0, while 34% were N1. No statistically significant difference was observed between serum nestin levels and ER, PR, HER2, Ki67, and p53 expression. Furthermore, no difference was observed between serum nestin levels and breast cancer histological type, size, N-stage, and grading. CONCLUSION: The diagnostic and prognostic role of circulating nestin for breast cancer was not confirmed and no correlation with immunohistochemistry results was observed. Thus, the necessity of larger prospective studies is enhanced.

Nuck Canal Endometriosis Following IVF Attempts in a Young Patient-Report of a Case.

INTRODUCTION: Endometriosis is a common benign condition affecting 10-15% of women of reproductive age. An unusual site of endometriosis is the canal of Nuck, which is a physiologically obliterated space in women spanning the area from the deep inguinal ring to the labia majora. CASE PRESENTATION: A 37-year-old woman, with a past medical history of several in vitro fertilization attempts, presented with a right-sided painful inguinal mass. She was subsequently offered surgical exploration and excision of the lesion, which revealed the presence of endometrial glands and stroma. DISCUSSION: Despite being a relatively common and benign pelvic condition, endometriosis can rarely manifest in the inguinal region, within the canal of Nuck. The treating physician should be cognizant of Nuck canal endometriosis, especially in young female patients presenting with an irreducible mass in the inguinal region and associated cyclic pain or infertility. CONCLUSION: When clinically and radiologically suspected, surgical excision is indicated to establish the diagnosis, provide symptomatic relief and guide further decision making.

Development and internal validation of a clinical prediction model for serious complications after emergency laparotomy.

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.

Objective assessment of cosmetic outcome after targeted intraoperative radiotherapy in breast cancer: results from a randomised controlled trial.

The international randomised targeted intraoperative radiotherapy (TARGIT) trial has demonstrated evidence of non-inferiority between the novel technique of TARGIT (intra-operative radiotherapy with Intrabeam(®)) and conventional external beam radiotherapy (EBRT) in women with early breast cancer in terms of the primary outcome measure of risk of local relapse within the treated breast. Cosmesis is an increasingly important outcome of breast conserving treatment with both surgery and radiotherapy contributing to this. It was unknown if the single high dose of TARGIT may lead to damaging fibrosis and thus impair cosmesis further, so we objectively evaluated the aesthetic outcome of patients within the TARGIT randomised controlled trial. We have used an objective assessment tool for evaluation of cosmetic outcome. Frontal digital photographs were taken at baseline (before TARGIT or EBRT) and yearly thereafter for up to 5 years. The photographs were analysed by BCCT.core, a validated software which produces a composite score based on symmetry, colour and scar. 342 patients were assessed, median age at baseline 64 years (IQR 59-68). The scores were dichotomised into Excellent and Good (EG), and Fair and Poor (FP). There were statistically significant increases in the odds of having an outcome of EG for patients in the TARGIT group relative to the EBRT group at year 1 (OR 2.07, 95 % CI 1.12-3.85, p = 0.021) and year 2 (OR 2.11, 95 % CI 1.0-4.45, p = 0.05). Following a totally objective assessment in a randomised setting, the aesthetic outcome of patients demonstrates that those treated with TARGIT have a superior cosmetic result to those patients who received conventional external beam radiotherapy.
