Imaging in gynecological disease (27): clinical and ultrasound characteristics of recurrent ovarian stromal cell tumors

OBJECTIVE

To describe the clinical and ultrasound characteristics of recurrent granulosa cell and Sertoli-Leydig cell tumors.

METHODS

This was a retrospective observational study performed at Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS, Rome (Gemelli center), Italy. Patients with a histological diagnosis of recurrent granulosa cell tumor or Sertoli-Leydig cell tumor were identified from the database of the Department of Gynecological Oncology. Those who had undergone a preoperative ultrasound examination at the Gemelli center between 2012 and 2020 were included, and the data retrieved from the original ultrasound reports. In all of these reports, the recurrent tumors were described using International Ovarian Tumor Analysis (IOTA) terminology. If a patient had more than one episode of relapse, information from all episodes was collected. If there was more than one recurrent tumor at the same ultrasound examination, all tumors were included. One expert sonographer also reviewed all available ultrasound images to identify typical ultrasound patterns using pattern recognition.

RESULTS

We identified 30 patients with a histological diagnosis of recurrent granulosa cell tumor (25 patients, 55 tumors) or Sertoli-Leydig cell tumor (five patients, seven tumors). All 30 had undergone at least one preoperative ultrasound examination at the Gemelli center and were included. These women had a total of 66 episodes of relapse, of which a preoperative ultrasound examination had been performed at the Gemelli center in 34, revealing 62 recurrent lesions: one in 22/34 (64.7%) episodes of relapse, two in 4/34 (11.8%) episodes and three or more in 8/34 (23.5%) episodes. Most recurrent granulosa cell tumors (38/55, 69.1%) and recurrent Sertoli-Leydig tumors (6/7, 85.7%) were classified as solid or multilocular-solid tumors, while 8/55 (14.5%) recurrent granulosa cell tumors and 1/7 (14.3%) recurrent Sertoli-Leydig cell tumors were unilocular cysts and 9/55 (16.4%) recurrent granulosa cell tumors were multilocular cysts. The nine unilocular cysts had contents that were anechoic (n = 2) or had low-level echogenicity (n = 7), had either smooth (n = 4) or irregular (n = 5) internal cyst walls, and ranged in largest diameter from 8 to 38 mm, with three being < 20 mm and five being 20-30 mm. On retrospective review of the images, two typical ultrasound patterns were described: small solid tumor measuring < 2 cm (15/62, 24.2%) and tumor with vascularized echogenic ground-glass-like content (12/62, 19.4%).

CONCLUSIONS

Some granulosa cell and Sertoli-Leydig cell recurrences manifest one of two typical ultrasound patterns, while some appear as unilocular cysts. These are usually classified as benign, but in patients being followed up for a granulosa cell tumor or Sertoli-Leydig cell tumor, a unilocular cyst should be considered suspicious of recurrence. © 2023 The Authors.

Innovative Ultrasound Criteria for the Diagnosis of Adenomyosis and Correlation with Symptoms: A Retrospective Re-Evaluation

The 2022 Delphi revision of the MUSA (Morphological Uterus Sonographic Assessment) criteria for the ultrasound diagnosis of adenomyosis divides the ultrasound signs for diagnosis into direct and indirect ones, considering the presence of at least one direct sign as a mandatory criterion. This study aimed to reclassify the patients referred to the Pelvic Pain specialist outpatient clinic of the Gynecological Clinic of Udine according to the new criteria, evaluating the number of overdiagnoses and the possible correlation between the direct and indirect signs and the patients' symptoms. 62 patients affected by adenomyosis were retrospectively recruited. The patients were then re-evaluated by ultrasound and clinically. At least one direct sign of adenomyosis was found in 52 patients, while 16% of the population examined did not present any. There was no statistically significant difference between patients presenting direct signs and those presenting none for the symptoms considered. According to the new criteria, 16% of the patients examined were not affected by adenomyosis; applying the new consensus to symptomatic patients could increase false negatives. In a population of symptomatic patients, the diagnosis of adenomyosis is still highly probable even without direct ultrasound signs, given the clinical symptoms and having ruled out other causes of such symptoms.

A cost-effectiveness analysis of an integrated clinical-radiogenomic screening program for the identification of BRCA 1/2 carriers (e-PROBE study)

Current approach to identify BRCA 1/2 carriers in the general population is ineffective as most of the carriers remain undiagnosed. Radiomics is an emerging tool for large scale quantitative analysis of features from standard diagnostic imaging and has been applied also to identify gene mutational status. The objective of this study was to evaluate the clinical and economic impact of integrating a radiogenomics model with clinical and family history data in identifying BRCA mutation carriers in the general population. This cost-effective analysis compares three different approaches to women selection for BRCA testing: established clinical criteria/family history (model 1); established clinical criteria/family history and the currently available radiogenomic model (49% sensitivity and 87% specificity) based on ultrasound images (model 2); same approach used in model 2 but simulating an improvement of the performances of the radiogenomic model (80% sensitivity and 95% specificity) (model 3). All models were trained with literature data. Direct costs were calculated according to the rates currently used in Italy. The analysis was performed simulating different scenarios on the generation of 18-year-old girls in Italy (274,000 people). The main outcome was to identify the most effective model comparing the number of years of BRCA-cancer healthy life expectancy (HLYs). An incremental cost-effectiveness ratio (ICER) was also derived to determine the cost in order to increase BRCA carriers-healthy life span by 1 year. Compared to model 1, model 2 increases the detection rate of BRCA carriers by 41.8%, reduces the rate of BRCA-related cancers by 23.7%, generating over a 62-year observation period a cost increase by 2.51 €/Year/Person. Moreover, model 3 further increases BRCA carriers detection (+ 68.3%) and decrease in BRCA-related cancers (- 38.4%) is observed compared to model 1. Model 3 increases costs by 0.7 €/Year/Person. After one generation, the estimated ICER in the general population amounts to about 3800€ and 653€ in model 2 and model 3 respectively. Model 2 has a massive effect after only one generation in detecting carriers in the general population with only a small cost increment. The clinical impact is limited mainly due to the current low acceptance rate of risk-reducing surgeries. Further multicentric studies are required before implementing the integrated clinical-radiogenomic model in clinical practice.

Use of oral GnRH antagonists combined therapy in the management of symptomatic uterine fibroids

Uterine fibroids have an impact on women’s lives due to their high prevalence, physical symptoms, their consequences on patients’ emotional and psychological well-being and loss of work productivity. The choice of therapeutical approaches varies depending on several factors, and therefore should be applied individually. Currently, there is an unmet need for good, reliable, uterine-sparing options. The oral GnRH antagonists (Elagolix, Relugolix, Linzagolix) represent a new alternative for the medical management of hormone-dependent gynaecological diseases such as uterine fibroids or endometriosis. They rapidly bind to the GnRH receptor, block endogenous GnRH activity and directly suppress LH and FSH production, avoiding unwanted flare-up effects. Some GnRH antagonists are marketed in combination with hormone replacement therapy add-back to counteract hypo-oestrogenic side effects. According to the registration trials, once-daily GhRH antagonist combination therapy results in a significant reduction in menstrual bleeding, as compared with placebo, and preserves bone mineral density, for up to 104 weeks. Further studies in the long term are needed to evaluate the whole impact of medical treatment of uterine fibroids on the management of this common women’s disease.

Risk perception and affective state on work exhaustion in obstetrics during the COVID-19 pandemic

A multicenter cross-sectional survey study involving four Italian University Hospitals was performed to test the hypothesis that negative affect and positive affect (affective dimensions) mediate the association between risk perception (perceived risk of infection and death; cognitive dimensions) and the feeling of work exhaustion (WE) among obstetrics healthcare providers (HCPs) during the Coronavirus Disease 2019 (COVID-19) pandemic. Totally, 570 obstetrics HCPs were invited to complete the 104-item IPSICO survey in May 2020. A theoretical model built on the tested hypothesis was investigated by structural equation modelling. The model explained 32.2% of the WE variance. Only negative affect mediated the association between cognitive dimensions and WE and also the association between WE and psychological well-being before the pandemic, experiences of stressful events, female gender, and dysfunctional coping. Non-mediated associations with WE were observed for work perceived as a duty, experience of stressful events, support received by colleagues, and the shift strategy. Only previous psychological well-being, support by colleagues, and shift strategies were inversely associated with WE. Based on study results, monitoring negative than positive affect appears superior in predicting WE, with practical implications for planning psychological interventions in HCPs at the individual, interpersonal, and organizational levels.

Diagnostic performance of ultrasound in assessing the extension of disease in advanced ovarian cancer

BACKGROUND

Surgical exploration remains the gold standard to evaluate the extension of disease and predict resectability. A laparoscopy-based scoring model was developed by Fagotti and colleagues in 2006 and updated in 2015, based on the intraoperative presence or absence of some specific cancer features. The model proved an overall accuracy rate of 77-100% and is considered the reference test to assess resectability in our Institution.

OBJECTIVES

The primary aim of the study was to analyze the agreement between preoperative ultrasound examination and laparoscopic findings in assessing the extension of intra-abdominal disease using six parameters described by Fagotti's score.

STUDY DESIGN

This is a prospective single-center observational study. Between January 2019 and June 2020, consecutive patients with clinical or radiological suspicion of ovarian/peritoneal cancer were assessed with preoperative ultrasound examination and assigned a score based on the six Fagotti's score parameters (great omentum, liver surface, lesser omentum/stomach/spleen, parietal peritoneum, diaphragms, bowel disease). Presence of mesenteral retraction of the small bowel and miliaric carcinomatosis on the serosa were also evaluated. Each parameter was correlated with laparoscopic findings. Concordance was calculated between ultrasound and laparoscopic parameters using Cohen's kappa(κ).

RESULTS

Cohen's κ ranged from 0.70 to 0.90 for carcinomatosis on the small/large bowel, supracolic omentum, liver surface and diaphragms. Cohen's κ test was lower for carcinomatosis on the parietal peritoneum (k=0.63) and on the lesser omentum/lesser curvature of the stomach/spleen (k=0.54). The agreement between ultrasound and surgical predictive index value (score) was κ=0.74. For the evaluation of mesenteral retraction and miliaric carcinomatosis, the agreement was low (k=0.57 and k=0.36 respectively).

CONCLUSIONS

The results of ultrasound and laparoscopy in the assessment of intra-abdominal tumor spread were in substantial agreement for almost all the parameters. Ultrasound examination can play a useful role in the preoperative management of patients with ovarian cancer when used in dedicated referral centers.

PARP Inhibitors Resistance: Mechanisms and Perspectives

Simple Summary

This review aims to analyze the emerging issue regarding PARP inhibitor’s resistance in tumors and their consequence on disease prognosis and treatment. Besides, we evaluate possible strategies and new therapeutic approaches to overcome PARPis resistance.

Abstract

PolyADP-ribose polymerase (PARP) inhibitors (PARPis) represent the first clinically approved drugs able to provoke “synthetic lethality” in patients with homologous recombination-deficient (HRD) tumors. Four PARPis have just received approval for the treatment of several types of cancer. Besides, another three additional PARPis underlying the same mechanism of action are currently under investigation. Despite the success of these targeted agents, the increasing use of PARPis in clinical practice for the treatment of different tumors raised the issue of PARPis resistance, and the consequent disease relapse and dismal prognosis for patients. Several mechanisms of resistance have been investigated, and ongoing studies are currently focusing on strategies to address this challenge and overcome PARPis resistance. This review aims to analyze the mechanisms underlying PARPis resistance known today and discuss potential therapeutic strategies to overcome these processes of resistance in the future.

Imaging in gynecological disease (23): clinical and ultrasound characteristics of ovarian carcinosarcoma

OBJECTIVE

To describe the clinical and ultrasound characteristics of ovarian carcinosarcoma.

METHODS

This was a retrospective multicenter study. Patients with a histological diagnosis of ovarian carcinosarcoma, who had undergone preoperative ultrasound examination between 2010 and 2019, were identified from the International Ovarian Tumor Analysis (IOTA) database. Additional patients who were examined outside of the IOTA study were identified from the databases of the participating centers. The masses were described using the terms and definitions of the IOTA group. Additionally, two experienced ultrasound examiners reviewed all available images to identify typical ultrasound features using pattern recognition.

RESULTS

Ninety-one patients with ovarian carcinosarcoma who had undergone ultrasound examination were identified, of whom 24 were examined within the IOTA studies and 67 were examined outside of the IOTA studies. Median age at diagnosis was 66 (range, 33-91) years and 84/91 (92.3%) patients were postmenopausal. Most patients (67/91, 73.6%) were symptomatic, with the most common complaint being pain (51/91, 56.0%). Most tumors (67/91, 73.6%) were International Federation of Gynecology and Obstetrics (FIGO) Stage III or IV. Bilateral lesions were observed on ultrasound in 46/91 (50.5%) patients. Ascites was present in 38/91 (41.8%) patients. The median largest tumor diameter was 100 (range, 18-260) mm. All ovarian carcinosarcomas contained solid components, and most were described as solid (66/91, 72.5%) or multilocular-solid (22/91, 24.2%). The median diameter of the largest solid component was 77.5 (range, 11-238) mm. Moderate or rich vascularization was found in 78/91 (85.7%) cases. Retrospective analysis of ultrasound images and videoclips using pattern recognition in 73 cases revealed that all tumors had irregular margins and inhomogeneous echogenicity of the solid components. Forty-seven of 73 (64.4%) masses appeared as a solid tumor with cystic areas. Cooked appearance of the solid tissue was identified in 28/73 (38.4%) tumors. No pathognomonic ultrasound sign of ovarian carcinosarcoma was found.

CONCLUSIONS

Ovarian carcinosarcomas are usually diagnosed in postmenopausal women and at an advanced stage. The most common ultrasound appearance is a large solid tumor with irregular margins, inhomogeneous echogenicity of the solid tissue and cystic areas. The second most common pattern is a large multilocular-solid mass with inhomogeneous echogenicity of the solid tissue. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Building a Personalized Medicine Infrastructure for Gynecological Oncology Patients in a High-Volume Hospital

Gynecological cancers require complex intervention since patients have specific needs to be addressed. Centralization to high-volume centers improves the oncological outcomes of patients with gynecological cancers. Research in gynecological oncology is increasing thanks to modern technologies, from the comprehensive molecular characterization of tumors and individual pathophenotypes. Ongoing studies are focusing on personalizing therapies by integrating information across genomics, proteomics, and metabolomics with the genetic makeup and immune system of the patient. Hence, several challenges must be faced to provide holistic benefit to the patient. Personalized approaches should also recognize the unmet needs of each patient to successfully deliver the promise of personalized care, in a multidisciplinary effort. This may provide the greatest opportunity to improve patients' outcomes. Starting from a narrative review on gynecological oncology patients' needs, this article focuses on the experience of building a research and care infrastructure for personalized patient management.

Practice changes in Italian Gynaecologic Units during the COVID-19 pandemic: a survey study

The impact of Coronavirus disease 2019 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown. Therefore, a survey was conducted among all Italian Gynaecological Units Directors in April 2020. The response rate was 90% (135/150). 77.8% of centres performed surgery only for oncologic or not deferrable pathologies, and 9.6% was closed. 68.7% of directors were at least moderately satisfied by published guidelines/recommendations, but 94.8% of respondents identified limitations, mainly (83%) the absent definition of benign non-deferrable pathology. Responders considered as non-deferrable severe endometriosis (69.6%), endometriosis with organ failure/dysfunction (74.1%), and unresponsive symptomatic fibroids (89.6%). Despite guidelines/recommendations, respondents treated ovarian (77%) and endometrial (71.6%) cancer as usual. Only a minority of respondents reduced the laparoscopic approach (11.2%) and adopted all recommended surgical precautions (9.6%). Compliance with available guidelines/recommendations appears incomplete. Reconsidering guidelines/recommendations regarding oncological cases and specify non-deferrable benign pathologies would improve guidelines/recommendations compliance.Impact statementWhat is already known on this subject? The SARS-CoV-2 pandemic has profoundly influenced medical routine practice worldwide. Surgery units have been forced to reduce or even completely restrict their activity to re-allocate human resources. Many major international gynaecological societies have released statements and guidelines, providing various recommendations to guide practice changes. However, the impact of the SARS-CoV-2 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown.What do the results of this study add? Study results provide evidence showing how the SARS-CoV-2 pandemic has changed surgical activity in the Italian Gynaecological Units. Most centres reduced surgical activity, limiting surgery only for oncologic or not deferrable pathologies. Moreover, our research shows the level of compliance and satisfaction with available guidelines/recommendations and where they need to be improved. Most directors were at least moderately satisfied but identified different limitations. Guidelines/recommendations do not provide enough details, such as the absent definition of benign non-deferrable pathologies.What are the implications of these findings for clinical practice and/or further research? The limited compliance with available guidelines/recommendations and identified limitations suggest reconsidering guidelines/recommendations focussing on identified gaps. Provide more details, such as specifying non-deferrable benign pathologies, would improve guidelines/recommendations compliance.

Adjuvant Treatment Recommendations in Early-Stage Endometrial Cancer: What Changes With the Introduction of The Integrated Molecular-Based Risk Assessment

Adjuvant therapy recommendations for endometrial cancer were historically based on the individual patient's risk of disease recurrence using clinicopathologic factors such as age, stage, histologic subtype, tumor grade, and lymphovascular space invasion. Despite the excellent prognosis for early stages, considerable under- and overtreatment remains. Integrated genomic characterization by the Cancer Genome Atlas (TCGA) in 2013 defined four distinct endometrial cancer subgroups (POLE mutated, microsatellite instability, low copy number, and high copy number) with possible prognostic value. The validation of surrogate markers (p53, Mismatch repair deficiency, and POLE) to determine these subgroups and the addition of other molecular prognosticators (CTNNB1, L1CAM) resulted in a practical and clinically useful molecular classification tool. The incorporation of such molecular alterations into established clinicopathologic risk factors resulted in a refined, improved risk assessment. Thus, the ESGO/ESTRO/ESP consensus in 2020 defined for the first time different prognostic risk groups integrating molecular markers. Finally, the feasibility and clinical utility of molecular profiling for tailoring adjuvant therapy in the high-intermediate-risk group is currently under investigation (NCT03469674).

Role of Immune Checkpoint Inhibitors in Cervical Cancer: From Preclinical to Clinical Data

Simple Summary

Cervical cancer represents one of the main leading causes of cancer-related mortality in women worldwide. In contrast to patients with early-stage disease, those with advanced, recurrent, or metastatic cervical cancer have a poor prognosis and new treatment strategies are needed. Immunotherapy has recently modified the natural course of different tumors, such as melanoma and lung cancer. The aim of this review is to evaluate the possible role of immune checkpoint inhibitors in cervical cancer treatment.

Abstract

Human papillomavirus (HPV) infection is the recognized cause of almost all cervical cancers. Despite the reduction in incidence due to a wide use of screening programs and a specific vaccine, the prognosis of cervical cancer remains poor, especially for late-stage and relapsed disease. Considering the elevated rates of PD-L1 expression in up to 80% of cervical cancers, a strong rationale supports the use of immunotherapy to restore the immune response against tumor. The aim of this review is to analyze the possible role of immune checkpoint inhibitors in cervical cancer treatment, with a particular focus on the rationale and on the results of phase I and II clinical trials. An overview of ongoing phase III studies with possible future areas of development is also provided.

The Psychological Impact of COVID-19 on Healthcare Providers in Obstetrics: A Cross-Sectional Survey Study

Objective: To assess the psychological distress of healthcare providers (HCPs) working in the field of obstetrics during the coronavirus disease 2019 (COVID-19) pandemic and to identify factors associated with psychological distress at the individual, interpersonal, and organizational level.

Design: Cross-sectional survey study.

Setting: Four University hospitals in Italy.

Participants: HCPs working in obstetrics, including gynecologists, residents in gynecology and obstetrics, and midwives.

Methods: The 104-item survey Impatto PSIcologico COVID-19 in Ostetricia (IPSICO) was created by a multidisciplinary expert panel and administered to HCPs in obstetrics in May 2020 via a web-based platform.

Main Outcome Measures: Psychological distress assessed by the General Health Questionnaire-12 (GHQ-12) included in the IPSICO survey.

Results: The response rate to the IPSICO survey was 88.2% (503/570), and that for GHQ-12 was 84.4% (481/570). Just over half (51.1%; 246/481) of the GHQ-12 respondents reported a clinically significant level of psychological distress (GHQ-12 ≥3). Psychological distress was associated with either individual (i.e., female gender, stressful experience related to COVID-19, exhaustion, and the use of dysfunctional coping strategies), interpersonal (i.e., lower family support, limitations in interactions with colleagues), and organizational (i.e., reduced perception of protection by personal protective equipment, perceived delays on updates and gaps in information on the pandemic) factors in dealing with the pandemic.

Conclusions: Results confirm the need for monitoring and assessing the psychological distress for HCPs in obstetrics. Interventions at the individual, interpersonal, and organizational level may relieve the psychological distress during the COVID-19 pandemic and foster resilience skills in facing emotional distress.

Immunotherapy in gynecological cancers

Immunotherapy has changed the natural history of several malignancies that, a decade ago, had a very poor prognosis, such as lung cancer and melanoma. Consequently, many attempts have been done to expand the indications of immunotherapy agents, predominantly immune checkpoint inhibitors (ICIs), in other cancers, including gynecological malignancies. Alongside promising results in cervical and endometrial neoplasms, there are not clear data on the benefit of ICIs as single agent or in combination with antiangiogenic agents in ovarian cancer (OC) and ongoing trials are focusing on combining ICIs with standard chemotherapy or PARP inhibitors. This chapter summarized the evidences of ICIs in gynecological malignancies and report the ongoing trials in cervical, endometrial and OC.

Oregovomab: an investigational agent for the treatment of advanced ovarian cancer

Introduction: Ovarian cancer (OC) represents the leading cause of death among gynecological cancers. Despite novel compound classes like vascular endothelial growth factor (VEGF) inhibitors or poly-ADP ribose polymerase (PARP) inhibitors are available, which improve significantly efficacy of platinum-based chemotherapy, OC prognosis remains poor and innovative strategies are needed. The induction of tumor specific immune response with a therapeutic intent is a very challenging approach. Oregovomab is a murine monoclonal antibody direct to the tumor-associated antigen CA125 that stimulate a host cytotoxic immune response against tumor cells expressing CA125. Areas covered: This paper reviews the preclinical and clinical published data underlying the use of oregovomab in advanced OC. A literature search was performed in PubMed for oregovomab, ovarian cancer, anti-CA125, and on ClinicalTrials.gov for currently ongoing trials. Expert opinion: Oregovomab demonstrated a significant improvement in progression-free and overall survival in advanced OC treatment when administered simultaneously with first-line chemotherapy. This promising schedule is currently investigated in a phase III trial. Since oral treatments as PARP-inhibitors have recently been approved in the OC first-line setting, the possible role of oregovomab needs still to be defined, also considering the intravenous route of administration. The easy to manage toxicity profile makes oregovomab an ideal candidate for association strategies.

Clinical and ultrasound characteristics of vaginal lesions

OBJECTIVE

Ultrasound examination represents the most important diagnostic method to preoperatively assess gynecological diseases. However, the ultrasound characteristics of vaginal pathologies are poorly investigated. The aim of this study was to describe the clinical and ultrasound characteristics of vaginal lesions detected at ultrasound.

METHODS

This was a single center, prospective, observational study including patients with vaginal masses examined from January 2017 to May 2019. Morphologic sonographic characteristics of the lesions were described as unilocular, multilocular, unilocular-solid, multilocular-solid, and solid. For the analysis, patients were grouped into a 'malignant group', including patients with confirmed malignancy at final histology, and a 'benign group', including patients with a confirmed benign pathology at final histology and patients without a histological diagnosis but with a lesion that manifested no changes during follow-up.

RESULTS

44 patients were enrolled. 22 (50%) of 44 lesions were benign: 12 (54.5%) of these underwent ultrasound follow-up and did not show any changes at the 12 month follow-up whereas 10 (45.5%) lesions had surgical excision which confirmed the benign nature. The remaining 22 (50%) of 44 lesions underwent surgery because of suspicion of malignancy: histology confirmed a malignancy in 20 (90.9%) of 22 cases. Benign lesions were described as follow: 11/24 (45.8%) unilocular, 3/24 (12.5%) multilocular with two locules, and 10/24 (41.7%) solid lesions. Malignant lesions were solid in 19/20 (95%) cases and multilocular-solid in 1/20 (5%). Most benign lesions had a color score of 1-2 (20/24, 83.4%) while malignant lesions had a color score of 3-4 (18/20, 90%).

CONCLUSION

A typical ultrasound image of a benign lesion was a unilocular cyst or hypoechoic solid mass with no or minimal vascularization on color Doppler examination. Malignant vaginal lesions were hypoechoic solid tumors with irregular margins and moderate/rich vascularization or multilocular-solid. Ultrasound should be used to supplement the clinician in the management of vaginal lesions.

Elective Treatment of Large-Bowel Obstruction in Asymptomatic Sigmoid Volvulus

BACKGROUND

Sigmoid volvulus is an uncommon cause of intestinal obstruction representing the 5% of all Western cases, associated with old age and a history of neurological and psychiatric condition. Generally, its diagnosis is established by clinical and radiologic findings. It often represents an emergency and it is commonly associated with pain, vomit and abdominal tenderness.

CASE PRESENTATION

We present a case of a 59 years old man, admitted to our emergency department, showing an abdominal X-Ray reporting a distention of large bowel,which was required due to presence of multiple diarrhea episodes during the previous 7 days. He had no significant past medical history and did not report constipation or subocclusive episode.

CONCLUSIONS

Volvulus should be considered in the differential diagnosis in adult and healthy patients with bowel obstructions. Surgery is, in all cases, the radical and definitive treatment since there is a higher mortality in case of recurrent volvulus. Despite the massive bowel distention, our choice was the elective open surgery. Primary anastomosis is feasible and safe and did not lead to any complications. In case of unsuccessful colonic decompression, evidence to support or refute the safety and effectiveness of laparoscopic surgical resection for treatment of patients with sigmoid volvulus disease is not yet proven.

Emerging role of immune checkpoint inhibitors in the treatment of ovarian cancer

INTRODUCTION

In recent years, ovarian cancer (OC) treatment has been enriched with many new target therapies, most of all antiangiogenic drugs and PARP inhibitors (PARPis), which have literally changed the natural history of the disease. The impressive results of immunotherapy in other malignancies, mainly melanoma and lung cancer, and the good signals of activity in gynecological neoplasms like cervical and microsatellite instable (MSI-H) endometrial cancer, opened the space to the introduction of immune-stimulatory drugs in ovarian cancer.

AREA COVERED

The goal of this article is to summarize the newest evidence on the use of immune check point inhibitors in OC trying to explain why, at present, this strategy has failed to improve clinical outcome and focusing on the possible strategies to overcome treatment failure.

EXPERT OPINION

Although numerous trials have been undertaken, only scanty results have been obtained so far with immune check-point inhibitors (ICIs) in OC either when used as single agents or in combination with antiangiogenic therapy and ongoing trials are exploring the association of ICIs with PARPis and other ICIs. A better knowledge of predictive biomarkers of response and mechanisms of immunotherapy resistance, will help in identifying the most appropriate population to treat with ICIs.

Newly diagnosed ovarian cancer: Which first-line treatment?

Poly ADP -Ribose Polymerase (PARP) inhibitors (PARPi) were firstly licensed for maintenance treatment in recurrent, platinum-sensitive, platinum responsive epithelial ovarian cancer patients, harboring or not a BRCA mutation. Three new phase III trials - PAOLA1/ENGOT-OV25, PRIMA/ENGOT-OV26 and VELIA/GOG-3005 - showed that there is a role for PARPi also in first-line setting, as maintenance or in combination with platinum-based chemotherapy. Nevertheless the published trials raised several questions on what is the best treatment according to the molecular and clinical characteristics of the treated patients. This review focuses on the published data in order to inform clinician decision making on what could be the best sequence or combination of treatments for the three molecular defined cohorts of patients emerging in the first line trials (the carriers of a BRCA mutation (BRCAmut), those with a deficiency in homologous recombination system (HRd) and those with a proficient homologous recombination system (HRp)) and put the newly published data in the context of the ovarian cancer treatment landscape.

Germline BRCA 1-2 status prediction through ovarian ultrasound images radiogenomics: a hypothesis generating study (PROBE study)

Radiogenomics is a specific application of radiomics where imaging features are linked to genomic profiles. We aim to develop a radiogenomics model based on ovarian US images for predicting germline BRCA1/2 gene status in women with healthy ovaries. From January 2013 to December 2017 a total of 255 patients addressed to germline BRCA1/2 testing and pelvic US documenting normal ovaries, were retrospectively included. Feature selection for univariate analysis was carried out via correlation analysis. Multivariable analysis for classification of germline BRCA1/2 status was then carried out via logistic regression, support vector machine, ensemble of decision trees and automated machine learning pipelines. Data were split into a training (75%) and a testing (25%) set. The four strategies obtained a similar performance in terms of accuracy on the testing set (from 0.54 of logistic regression to 0.64 of the auto-machine learning pipeline). Data coming from one of the tested US machine showed generally higher performances, particularly with the auto-machine learning pipeline (testing set specificity 0.87, negative predictive value 0.73, accuracy value 0.72 and 0.79 on training set). The study shows that a radiogenomics model on machine learning techniques is feasible and potentially useful for predicting gBRCA1/2 status in women with healthy ovaries.

Italian consensus conference on management of uterine sarcomas on behalf of S.I.G.O. (Societa' italiana di Ginecologia E Ostetricia)

BACKGROUND

Uterine sarcomas are very rare tumours with different histotypes, molecular features and clinical outcomes; therefore, it is difficult to carry out prospective clinical trials, and this often results in heterogeneous management of patients in the clinical practice.

AIM

We planned to set up an Italian consensus conference on these diseases in order to provide recommendations on treatments and quality of care in our country.

RESULTS

Early-stage uterine sarcomas are managed by hysterectomy + bilateral salpingo-oophorectomy according to menopausal status and histology; lymphadenectomy is not indicated in patients without bulky nodes, and morcellation must be avoided. The postoperative management is represented by observation, even though chemotherapy can be considered in some high-risk patients. In early-stage low-grade endometrial stromal sarcoma and adenosarcomas without sarcomatous overgrowth, hormonal adjuvant treatment can be offered based on hormone receptor expression. In selected cases, external beam radiotherapy ± brachytherapy can be considered to increase local control only. Patients with advanced disease involving the abdomen can be offered primary chemotherapy (or hormonal therapy in the case of low-grade endometrial stromal sarcoma and adenosarcoma without sarcomatous overgrowth), even if potentially resectable in the absence of residual disease in order to test the chemosensitivity (or hormonosensitivity); debulking surgery can be considered in patients with clinical and radiological response. Chemotherapy is based on anthracyclines ± ifosfamide or dacarbazine. Palliative radiotherapy can be offered for symptom control, and stereotactic radiotherapy can be used for up to five isolated metastatic lesions.

CONCLUSIONS

Treatment of uterine sarcoma should be centralised at referral centres and managed in a multidisciplinary setting.

Role of minimally invasive surgery versus open approach in patients with early-stage uterine carcinosarcomas: a retrospective multicentric study

Objective

The aim of this retrospective study was to compare surgical and survival outcome in only patients with early-stage UCSs managed by laparotomic surgery (LPT) versus minimally invasive surgery (MIS).

Methods

Data were retrospectively collected in four Italian different institutions. Inclusion criteria were UCS diagnosis confirmed by the definitive histological examination, and stage I or II according to the FIGO staging system.

Results

Between August 2000 and March 2019, the data relative to 170 patients bearing UCSs were collected: of these, 95 were defined as early-stage disease (stage I–II) based on the histological report at the primary surgery, and thus were included in this study. Forty-four patients were managed by LPT, and 51 patients were managed by MIS. The operative time was lower in the MIS group versus the LPT group (p value 0.021); the median estimated blood loss was less in the MIS group compared to the median of LPT group (p value < 0.0001). The length of hospital stay days was shorter in the MIS patients (p value < 0.0001). Overall, there were eight (8.4%) post-operative complications; of these, seven were recorded in the LPT group versus one in the MIS group (p value 0.023). There was no difference in the disease-free survival (DFS) and overall survival (OS) between the two groups.

Conclusion

There was no difference of oncologic outcome between the two approaches, in face of a more favourable peri-operative and post-operative profile in the MIS group.

Integration of PARP-inhibitors in ovarian cancer therapy

Poly-ADP-ribose polymerase inhibitors (PARP-I) represent one of the most attractive and promising class of biological agents studied both in relapsed ovarian cancer (OC) and in the advanced setting. The availability of this new class of drugs has changed the clinical management of OC ensuring an unprecedented advance in such an aggressive cancer. Three oral PARP-I are currently available: olaparib, niraparib and rucaparib. Another two are in active clinical exploration: veliparib and talazoparib. Here the authors report clinical data with PARP-I with a particular emphasis on the phase II and III trials that support PARP-I approval by regulatory agencies in OC patients.

Perineal trauma with anal avulsion: case report

Anorectal avulsion is an exceptional rectal trauma. In this kind of lesions, the anus and the sphincter no longer join the perineum and are pulled upward. We present a case of 34-years-old patient who was admitted because of a pelvic-perineal trauma, presenting a partial anorectal avulsion, exposed femoral fracture with thigh's lacerated-contused wound. Our treatment included primary plastic of the internal anal sphincter with replanting of the rectum on the anal canal and a diverting loop sigmoid colostomy (SCS), so as to prevent sepsis. Closure of the protective SCS was performed four months after the trauma.

Imaging in gynecological disease (16): clinical and ultrasound characteristics of serous cystadenofibromas in adnexa

OBJECTIVE

To describe the clinical and ultrasound characteristics of serous cystadenofibromas in the adnexa.

METHODS

This was a retrospective study of patients identified in the International Ovarian Tumor Analysis (IOTA) database, who had a histological diagnosis of serous cystadenofibroma and had undergone preoperative ultrasound examination by an experienced ultrasound examiner, between 1999 and 2012. In the IOTA database, which contains data collected prospectively, the tumors were described using the terms and definitions of the IOTA group. In addition, three authors reviewed, first independently and then together, ultrasound images of serous cystadenofibromas and described them using pattern recognition.

RESULTS

We identified 233 women with a histological diagnosis of serous cystadenofibroma. In the IOTA database, most cystadenofibromas (67.4%; 157/233) were described as containing solid components but 19.3% (45/233) were described as multilocular cysts and 13.3% (31/233) as unilocular cysts. Papillary projections were described in 52.4% (122/233) of the cystadenofibromas. In 79.5% (97/122) of the cysts with papillary projections, color Doppler signals were absent in the papillary projections. Most cystadenofibromas (83.7%; 195/233) manifested no or minimal color Doppler signals. On retrospective analysis of 201 ultrasound images of serous cystadenofibromas, using pattern recognition, 10 major types of ultrasound appearance were identified. The most common pattern was a unilocular solid cyst with one or more papillary projections, but no other solid components (25.9%; 52/201). The second most common pattern was a multilocular solid mass with small solid component(s), but no papillary projections (19.4%; 39/201). The third and fourth most common patterns were multi- or bilocular cyst (16.9%; 34/201) and unilocular cyst (11.9%; 24/201). Using pattern recognition, shadowing was identified in 39.8% (80/201) of the tumors, and microcystic appearance of the papillary projections was observed in 34 (38.6%) of the 88 tumors containing papillary projections.

CONCLUSIONS

The ultrasound features of serous cystadenofibromas vary. The most common pattern is a unilocular solid cyst with one or more papillary projections but no other solid components, with absent color Doppler signals. Most serous cystadenofibromas were poorly vascularized on color Doppler examination and many manifested acoustic shadowing. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Clinical outcome of recurrent endometrial cancer: analysis of post-relapse survival by pattern of recurrence and secondary treatment

INTRODUCTION

Recurrence of endometrial cancer is an important clinical challenge, with median survival rarely exceeding 12 months. The aim of this study was to analyze patterns of endometrial cancer recurrence and associations of these patterns with clinical outcome.

METHODS

The study included patients with endometrial cancer who underwent primary surgical treatment with or without adjuvant treatment between July 2004 and June 2017 at the Gynaecologic Oncology Unit of one of three tertiary hospitals of the Catholic University Network in Italy with complete follow-up data available. Information on the date and pattern of recurrence was retrieved for each relapse. Post-relapse survival was recorded as the time from the date of recurrence to the date of death or last follow-up. Survival probabilities were compared using log rank tests, and associations of clinico-pathological characteristics with post-relapse survival were tested using Cox's regression models.

RESULTS

A total of 1503 patients were included in the analysis. We identified 210 recurrences (14.0%) and 105 deaths (7.0%) at a median follow-up of 34 months (range 1-162). One hundred and fifty-eight recurrences (78.1%) occurred during the first two years of follow-up. Most recurrences were multifocal (n=121, 57.6%) and involved extrapelvic sites (n=38, 65.7%). Parameters associated with post-relapse survival in the univariate analysis included histotype, grade, time to recurrence, pattern of recurrence, number of relapsing lesions, and secondary radical surgery. Only the pattern of recurrence and secondary radical surgery were independent predictors of post-relapse survival in the multivariate analysis (p=0.025 and p=0.0001, respectively).

CONCLUSION

Lymph node recurrence and the feasibility of secondary radical surgery were independent predictors of post-relapse survival in patients with recurrent endometrial cancer.

Imaging in gynecological disease (15): clinical and ultrasound characteristics of uterine sarcoma

OBJECTIVE

To describe the clinical and ultrasound characteristics of uterine sarcomas.

METHODS

This was a retrospective multicenter study. From the databases of 13 ultrasound centers, we identified patients with a histological diagnosis of uterine sarcoma with available ultrasound reports and ultrasound images who had undergone preoperative ultrasound examination between 1996 and 2016. As the first step, each author collected information from the original ultrasound reports from his/her own center on predefined ultrasound features of the tumors and by reviewing the ultrasound images to identify information on variables not described in the original report. As the second step, 16 ultrasound examiners reviewed the images electronically in a consensus meeting and described them using predetermined terminology.

RESULTS

We identified 116 patients with leiomyosarcoma, 48 with endometrial stromal sarcoma and 31 with undifferentiated endometrial sarcoma. Median age of the patients was 56 years (range, 26-86 years). Most patients were symptomatic at diagnosis (164/183 (89.6%)), the most frequent presenting symptom being abnormal vaginal bleeding (91/183 (49.7%)). Patients with endometrial stromal sarcoma were younger than those with leiomyosarcoma and undifferentiated endometrial sarcoma (median age, 46 years vs 57 and 60 years, respectively). According to the assessment by the original ultrasound examiners, the median diameter of the largest tumor was 91 mm (range, 7-321 mm). Visible normal myometrium was reported in 149/195 (76.4%) cases, and 80.0% (156/195) of lesions were solitary. Most sarcomas (155/195 (79.5%)) were solid masses (> 80% solid tissue), and most manifested inhomogeneous echogenicity of the solid tissue (151/195 (77.4%)); one sarcoma was multilocular without solid components. Cystic areas were described in 87/195 (44.6%) tumors and most cyst cavities had irregular walls (67/87 (77.0%)). Internal shadowing was observed in 42/192 (21.9%) sarcomas and fan-shaped shadowing in 4/192 (2.1%). Moderate or rich vascularization was found on color-Doppler examination in 127/187 (67.9%) cases. In 153/195 (78.5%) sarcomas, the original ultrasound examiner suspected malignancy. Though there were some differences, the results of the first and second steps of the analysis were broadly similar.

CONCLUSIONS

Uterine sarcomas typically appear as solid masses with inhomogeneous echogenicity, sometimes with irregular cystic areas but only very occasionally with fan-shaped shadowing. Most are moderately or very well vascularized. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Synchronous primary cancers of endometrium and ovary vs endometrial cancer with ovarian metastasis: an observational study

OBJECTIVE

To compare the ultrasound characteristics of patients with synchronous primary cancers of the endometrium and ovary vs those of patients with endometrial cancer with ovarian metastasis.

METHODS

This was a single-institution retrospective observational study of patients with a histological diagnosis of endometrial cancer and an ovarian malignant mass, who had undergone preoperative ultrasound examination at our unit. Based on the histological diagnosis, patients were classified into two groups: those with synchronous primary cancers of the endometrium and ovary (synchronous group) and patients with endometrial cancer with ovarian metastasis (metastasis group). We compared the ultrasound features of ovarian malignant masses and of endometrial cancers between the two groups. Student's t-test, Mann-Whitney U-test, χ² test or Fisher's exact test were used for comparisons of variables between the two histological groups, as appropriate.

RESULTS

We identified 131 patients, of whom 51 had synchronous primary cancers of the endometrium and ovary (synchronous group) and 80 had endometrial cancer with ovarian metastasis (metastasis group). On ultrasound examination, ovarian masses in the synchronous group were more often multilocular-solid and less often bilateral than those in the metastasis group. With respect to the ultrasound features of the endometrial lesions, the median largest diameter was 29 (range, 11-118) mm in the synchronous group in comparison with 51.5 (range, 6-150) mm in the metastasis group (P < 0.0001). Endometrial lesions in the synchronous group presented more often with no myometrial infiltration and less often with a multiple-vessel pattern on color Doppler compared with the endometrial lesions in the metastasis group.

CONCLUSIONS

Synchronous primary cancers of the endometrium and ovary have significantly different sonomorphological patterns compared with endometrial cancer with ovarian metastasis. Ovarian masses in women with synchronous primary cancers of the endometrium and ovary appeared as unilateral multilocular-solid or solid masses, whereas ovarian masses in women with endometrial cancer with ovarian metastasis were mostly bilateral solid masses. The different sonomorphology of these two cancers may facilitate their preoperative identification, helping the surgeon to determine optimum management for the patient. Copyright © 2019 ISUOG.

Imaging in gynecological disease (14): clinical and ultrasound characteristics of ovarian clear cell carcinoma

OBJECTIVE

To describe the clinical and ultrasound characteristics of ovarian pure clear cell carcinoma.

METHODS

This was a retrospective study involving data from 11 ultrasound centers. From the International Ovarian Tumor Analysis (IOTA) database, 105 patients who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 1999 and 2016 were identified with a histologically confirmed pure clear cell carcinoma of the ovary. An additional 47 patients diagnosed with pure clear cell carcinoma between 1999 and 2016 and with available complete preoperative ultrasound reports were identified retrospectively from the databases of the departments of gynecological oncology in the participating centers. The ultrasound images of all tumors were described using IOTA terminology. Clinical and ultrasound characteristics were analyzed for the whole group, and separately, for patients with and those without histologically confirmed endometriosis, and for patients with evidence of tumor developing from endometriosis.

RESULTS

Median age of the 152 patients was 53.5 (range, 28-92) years and 92/152 (60.5%) tumors were FIGO Stage I. Most tumors (128/152, 84.2%) were unilateral. On ultrasound examination, all tumors contained solid components and 36/152 (23.7%) were completely solid masses. The median largest diameter of the lesion was 117 (range, 25-310) mm. Papillary projections were present in 58/152 (38.2%) masses and, in most of these (51/56, 91.1%), vascularized papillary projections were seen. Information regarding the presence, site and type of pelvic endometriosis at histology was available for 130/152 patients. Endometriosis was noted in 54 (41.5%) of these. In 24/130 (18.6%) patients, the tumor was judged to have developed from endometriosis. Patients with, compared to those without, evidence of tumor developing from endometriosis were younger (median 47.5 vs 55.0 years, respectively), and ground-glass echogenicity of cyst fluid was more common in pure clear cell cancers developing from endometriosis (10/20 vs 13/79 (50.0% vs 16.5%), respectively).

CONCLUSIONS

Ovarian pure clear cell carcinoma is usually diagnosed at an early stage and typically appears as a large unilateral mass with solid components. Patients with clear cell carcinoma developing from endometriosis are younger than other patients with clear cell carcinoma, and clear cell cancers developing from endometriosis more often manifest ground-glass echogenicity of cyst fluid.

TET2 gene expression and 5-hydroxymethylcytosine level in multiple sclerosis peripheral blood cells

Aberrant DNA methylation can lead to genome destabilization and to deregulated gene expression. Recently, 5-hydroxymethylcytosine (5hmC), derived from oxidation of 5-methylcytosine (5mC) by the Ten-Eleven Translocation (TET) enzymes, has been detected. 5hmC is now considered as a new epigenetic DNA modification with relevant roles in cell homeostasis regulating DNA demethylation and transcription. Our aim was to investigate possible changes in the DNA methylation/demethylation machinery in MS. We assessed the expression of enzymes involved in DNA methylation/demethylation in peripheral blood mononuclear cells (PBMCs) from 40 subjects with MS and 40 matched healthy controls. We performed also, DNA methylation analysis of specific promoters and analysis of global levels of 5mC and 5hmC. We show that TET2 and DNMT1 expression is significantly down-regulated in MS PBMCs and it is associated with aberrant methylation of their promoters. Furthermore, 5hmC is decreased in MS PBMCs, probably as a result of the diminished TET2 level.

Ascaris Lumbricoides infestation and intestinal MZBCL: a surgical and radiological perspective

Ascaris Lumbricoides is the most common worm found in human beings and it is the largest of the intestinal nematodes parasitizing humanity. The most common complication of Ascariasis is mechanical bowel obstruction caused by a large number of worms. Bowel obstruction can also be caused by various toxins released by the worms. A large worm bolus can also cause volvulus or intussusception. We report a case of Intestinal Obstruction due to an Ileal MZBCL in an Ascaris. Lumbricoides infestation setting.

Validation of suitable internal control genes for expression studies in aging

Quantitative data from experiments of gene expression are often normalized through levels of housekeeping genes transcription by assuming that expression of these genes is highly uniform. This practice is being questioned as it becomes increasingly clear that the level of housekeeping genes expression may vary considerably in certain biological samples. To date, the validation of reference genes in aging has received little attention and suitable reference genes have not yet been defined. Our aim was to evaluate the expression stability of frequently used reference genes in human peripheral blood mononuclear cells with respect to aging. Using quantitative RT-PCR, we carried out an extensive evaluation of five housekeeping genes, i.e. 18s rRNA, ACTB, GAPDH, HPRT1 and GUSB, for stability of expression in samples from donors in the age range 35-74 years. The consistency in the expression stability was quantified on the basis of the coefficient of variation and two algorithms termed geNorm and NormFinder. Our results indicated GUSB be the most suitable transcript and 18s the least for accurate normalization in PBMCs. We also demonstrated that aging is a confounding factor with respect to stability of 18s, HPRT1 and ACTB expression, which were particularly prone to variability in aged donors.

Primary psoas abscess in a patient affected by acquired immunodeficiency syndrome: a rare case according to the reviewed literature

Abscesses of the psoas muscle can be divided into primary and secondary. In the primary ones, it is not possible to identify any further infected site. The localization to this muscle is due to its rich vascularization and Staphylococcus aureus is the most frequent aetiological agent of the infection. Treatment requires the use of appropriate antibiotics, as well as surgical or percutaneous drainage of the abscess. The percutaneous drainage is much less invasive and a low risk in the patients with acquired immunodeficiency syndrome, and is effective for draining even multiloculated abscess. The authors present a rare case of primary psoas abscess in patient affected by acquired human immunodeficiency syndrome, showing a mass in the inferior lumbar region through the lumbar triangle of Petit and fever. Treatment consisting in percutaneous drainage combined with systemic antibiotic administration was successful.

[Functional results of experimental autologous transplantation of the pancreas]

The autotransplant of the left lobe of the pancreas in the latero-cervical region has been successfully performed in 38 adult beagles with a mean cold ischemia time of 52 minutes. Juice volume and amylase, protein and bicarbonate outputs were resumed postoperatively as soon as 6 hours. A single case of thrombosis of the mesenteric vein occurred; all other pancreatic grafts showed good histological vitality at 30 days. This procedure of autografting is proposed as a valid experimental model for the pathophysiologic study of acute pancreatitis.

Incidence of incisional hernia following emergency abdominal surgery

BACKGROUND

A retrospective study was conducted to determine incidence and predisposing factors of incisional hernia after an emergency midline laparotomy.

PATIENTS AND METHODS

The study population consisted in 197 patients of whom 138 were followed-up for 2 years after surgery.

RESULTS

An incisional hernia developed in 25 (18.1%) patients at a mean follow-up of 11.2 months. Multivariate analysis showed the importance of age (> 60 years, p < 0.004), obesity (p < 0.008) and occurrence of post-operative wound infection (p < 0.00001) for the development of an incisional hernia. Univariate analysis showed that intestinal occlusion (p < 0.02), peritonitis (p < 0.006), upper abdominal access (p < 0.04) and post-operative wound infection (p < 0.003) in older patients and obesity (p < 0.003) and the presence of a neoplasm (p < 0.006) in younger patients, played a significant role. The comparison between young and old patients showed that upper abdominal access (p < 0.007), interrupted and layered wound closure (p < 0.02 and p < 0.01, respectively) and contamination of the operative field (p < 0.004) played a statistically significant role in older patients.

CONCLUSIONS

The rate of incisional hernia after an emergency midline laparotomy is higher than after elective procedures. However, it could be reduced with proper attention to the suture technique, i.e. mass and continuous suture, better preparation of the operative field and scrupulous sterility throughout the procedure in order to decrease the incidence of post-operative wound infection.

Influence of acute cholecystitis on surgical strategy and outcome of inapparent carcinoma of the gallbladder: a report on two cases

Unsuspected microscopic adenocarcinoma (T1) of the gallbladder was identified after surgery in two patients who underwent urgent open cholecystectomy for acute cholecystitis. In spite of the tumor being at an early stage both patients died after few months for local and disseminated tumor recurrence. The influence of the associated inflammatory disease of the gallbladder on the outcome of patients with inapparent gallbladder carcinoma is discussed and a more aggressive surgical strategy is suggested.

Influence of blunt needles on surgical glove perforation and safety for the surgeon

BACKGROUND

Round-tipped blunt needle (BN) may decrease the risk of needlestick injuries and hand contamination. We prospectively determined the incidence of glove perforations in emergency abdominal procedures and the efficacy of BN in increasing the safety for surgeons.

METHODS

Two hundred patients were randomized to undergo closure of the abdominal fascia using sharp needle (SN) or BN. Gloves were tested at the end of the procedure.

RESULTS

Surgeons had 14 needlestick injuries and 76 perforations recorded in 69 pair of gloves. Sharp needles were responsible for all injuries and 58 (76%) perforations (P < 0.00004 and P < 0.00001, respectively). This difference was still higher when considering the perforations related to the abdominal fascia closure (BN 7% versus SN 50%; P < 0.0006).

CONCLUSION

The risk of glove perforation is sevenfold greater if SN are used. Blunt needles reduce sharp injuries and improve safety for surgeons.

Inferior vena cava involvement by a left side adrenocortical carcinoma: operative and prognostic considerations

We report the fifth case of neoplastic involvement of the infrahepatic portion of the inferior vena cava, observed in a young woman affected by a left adrenal cortical carcinoma. The intracaval extension of a neoplastic thrombus from an adrenal tumor is a rare complication that should not be considered a dismal prognostic factor and does not contraindicate tumor resection with curative intent. Caval invasion must be preoperatively investigated to plan the correct surgical access and avoid the risk of neoplastic embolization.
