The challenging screen detection of ovarian cancer in BRCA mutation carriers adhering to a 6-month follow-up program: results from a 6-years surveillance.

OBJECTIVE: Approximately 25% of ovarian cancer (OC) cases are related to an inherited predisposition. Genetic mutations for the oncosuppressor genes BRCA1 and 2 have the best-known linkage to a higher incidence of OC and breast cancer, in approximately 70% to 80% of hereditary OC cases. To provide the first comprehensive clinical description of screen-detected (SD) OCs during a 6-years surveillance of a cohort of young BRCA carriers and carriers who refuse risk-reducing salpingo-oophorectomy. METHODS: A prospective cohort study in a university hospital describing 191 women with BRCA1 and 2 mutations adhering continuously to our surveillance between 2015 and 2020, including a 6-monthly evaluation of cancer antigen 125 (CA 125) with concomitant transvaginal ultrasound (TVUS) performed by a dedicated specialist. Main outcomes were tumor's laterality, CA 125 at diagnosis, TVUS and computed tomography (CT) findings. RESULTS: Risk-reducing salpingo-oophorectomy was performed in 58/191 (30.4%) of mutation carriers during the study period (one OC case identified). Nine SD-OCs and no interval OCs were found in the remaining 133 women. OCs (FIGO stage I or II: 88.9%) occur mainly in BRCA 1 (77.8%), being bilateral in 85.7% BRCA 1 and unilateral in 100% BRCA 2. No lesions involved only the tubes: left ovaries/tubes were more frequently involved. We have described three new possible scenarios regarding imaging: 1) Evident cases (33.3%, TVUS and CT obvious for OC, CA 125 sensitivity: 100%), 2) Possible cases (55.6%, TVUS and CT are in general accordance, documenting new TVUS signs: increased solid pattern of the ovary with peripheral cortical small cysts, hypoechoic circular mass near the ovary, intraparenchymal small hyperechoic foci), and 3) Hidden cases (11.1%, the smallest lesion but the highest stage (IIIA2), with CA 125 44.2 U/mL and concomitant endometrial hyperplasia). CONCLUSIONS: Different diagnostic tools must integrate to ensure early diagnosis of OC in BRCA mutation carriers adhering to a follow-up program.

Prostatic artery embolization for the management of benign prostatic hyperplasia/lower urinary tract symptoms in elderly patients unfit for surgery: Our initial experience. / Embolización arteria prostática para el manejo de la hiperplasia benigna de próstata/síndrome tracto urinario inferior en pacientes añosos no candidatos a cirugía: nuestra experiencia inicial.

OBJECTIVE: To evaluate the safety and efficacy of prostatic artery embolization in the management of LUTS secondary to BPH in elderly patients unfit for surgery. MATERIALS AND METHODS: 17 elderly patients with moderate to severe LUTS/BPH were included in the study and treated with prostatic artery embolization. The patients were evaluated by transrectal ultrasonography (to assess prostate size), IPSS, and PVR urine volume preoperatively and 6 months after the procedure. RESULTS: The mean age of patients was 76.67 ± 7.69. The mean prostate volume was 139.8 ± 81.83 g. The mean preoperative IPSS and PVR were 23 ± 5.4, and 94.43 ± 88.94 ml, respectively. The mean operative time was 90 minutes. Only three patients suffered from postoperative complications (two patients suffered from urinary tract infection and one patient had partial penile necrosis). At 6 months follow up, there was a significant reduction in the prostate volume (101 ± 73.65 cc), IPSS (12.5 ± 3.65), and PVR urine volume (48.64 ± 43.55). CONCLUSION: prostatic artery embolization is a safe and effective nonsurgical alternative treatment of BPH/LUTS particularly in elderly patients with multiple comorbidities.

Unexpected tumor response to palliative pelvic radiotherapy in mismatch repair-deficient advanced prostate cancer: a case report.

BACKGROUND: Mismatch-repair-deficiency resulting in microsatellite instability (MSI) may confer increased radiosensitivity in locally advanced/metastatic tumors and thus radiotherapy (RT) potentially might have a changing role in treating this subset of patients, alone or in combination with checkpoint inhibitors. CASE PRESENTATION: We report a 76 year-old Italian male patient presenting with locally advanced undifferentiated prostate cancer (LAPC), infiltrating bladder and rectum. Molecular analysis revealed high-MSI with an altered expression of MSH2 and MSH6 at immunohistochemistry. Two months after 6 chemotherapy cycles with Docetaxel associated to an LHRH analogue, a computed tomography scan showed stable disease. After palliative RT (30 Gy/10 fractions) directed to the tumor mass with a 3D-conformal setup, a follow-up computed tomography scan at 8 weeks revealed an impressive response that remained stable at computed tomography after 9 months, with sustained biochemical response. To our knowledge, this is the first case of such a sustained response to low dose RT alone in high-MSI LAPC. CONCLUSIONS: Routine evaluation of MSI in patients with locally problematic advanced tumors might change treatment strategy and treatment aim in this setting, from a purely palliative approach to a quasi-curative paradigm.

MRI of placenta accreta: diagnostic accuracy and impact of interventional radiology on foetal-maternal delivery outcomes in high-risk women.

OBJECTIVE: To assess accuracy and reproducibility of MRI diagnosis of invasive placentation (IP) in high-risk patients and to evaluate reliability of MRI features. Secondary aim was to evaluate impact of interventional radiology (IR) on delivery outcomes in patients with IP at MRI. METHODS: 26 patients (mean age 36.24 y/o,SD 6.16) with clinical risk-factors and echographic suspicion of IP underwent 1.5 T-MRI. Two readers reviewed images. Gold-standard was histology in hysterectomised patients and obstetric evaluation at delivery for patients with preserved uterus. Accuracy and reproducibility of MRI findings were calculated. RESULTS: Incidence of IP was 50% (13/26) and of PP was 11.54% (3/26). MRI showed 100% sensitivity (95% CI = 75.3-100%) and 92.3% specificity (95% CI = 64.0-100%) in the diagnosis of IP. Gold-standard was histology in 10 cases and obstetric evaluation in 16. MRI findings with higher sensitivity were placental heterogeneity, uterine bulging and black intraplacental bands. Uterine scarring, placental heterogeneity, myometrial interruption and tenting of the bladder showed better specificity. MRI inter-rater agreement with Cohen's K was 1. 11 patients among 14 with MRI diagnosis of IP received IR assistance with positive impact on delivery outcomes in terms of blood loss, red cells count, intense care unit length of stay, days of hospitalisation and risk of being transfused. CONCLUSION: MRI is an accurate and reproducible technique in prenatal diagnosis of IP. MRI helps planning a safe and appropriate delivery eventually assisted by IR, which positively affects foetal and maternal outcomes. ADVANCES IN KNOWLEDGE: The adoption of MRI evaluation in patients with high risk of invasive placentation allows a more accurate diagnosis in terms of both presence of the disease and its extension to or through or even beyond the myometrium. This led to a better dedicated delivery management with eventual adoption of interventional radiology with a global positive effect on foetal and maternal outcomes.

Imaging features of uterine and ovarian fibromatosis in Nevoid Basal Cell Carcinoma Syndrome.

Gorlin-Goltz Syndrome also known as Nevoid Basal Cell Carcinoma Syndrome is an autosomal dominant multisystem disorder. It is characterized by basal cell carcinomas, odontogenic keratocysts, skeletal abnormalities and in a minority of female patients bilateral calcified ovarian fibromas. It is challenging to radiologically assess ovarian fibromas as they have similar imaging patterns to some malignant ovarian lesions. However, it is vitally important to differentiate between benign and malignant lesions to determine patients' suitability for fertility-sparing surgery. This report describes a case of a 25 year-old patient with Gorlin-Goltz Syndrome and bilateral ovarian fibromas.

Transvaginal ultrasound assessment of uterine scar after previous caesarean section: comparison with 3T-magnetic resonance diffusion tensor imaging.

PURPOSE: This study aimed to evaluate 3-T magnetic resonance imaging in the analysis of caesarean scars in women with prior caesarean section (pCS) and investigate the potential added value of diffusion tensor imaging (3T-MR-DTI) with fibre tracking reconstruction, compared with transvaginal ultrasound (TVUS). METHODS: Thirty women who had previously undergone elective CS in a singleton pregnancy at term were examined (19 women with one pCS formed group 1 and 11 women with two pCS formed group 2). Patients underwent TVUS and 3T-MR-DTI within 2 days. Twelve women with prior vaginal delivery served as controls and underwent only 3T-MR. Uterine fibre architecture was depicted by MR-DTI with 3D tractography reconstruction providing quali-quantitative analysis of fibre, described as the reduction of number of longitudinal fibres that run through the uterine scar. RESULTS: Six subjects were excluded. According to 3T-MR morphology, scars were described as linear (n = 12) and retracting (n = 12); disagreement with TVUS was 54 %. The thickness of myometrium at the scar level was found to be significantly greater with 3T-MR compared to TVUS in linear scars (p = 0.01). No difference was found among retracting scars. In controls, according to 3T-MR-DTI, longitudinal myometrial fibres running in the anterior wall were similar to those in the posterior wall at same level -2 %; -27 % + 22 %). In groups 1 and 2 there was significant reduction in anterior fibres compared to posterior ones (-53 %; -77 % - 34 %; p = 0.0001). Among retracting scars, fibre reduction was significantly higher compared to linear scars, p < 0.016. CONCLUSIONS: The added value of 3T-MR with DTI lies in the prompt evaluation of muscle fibre remaining at scar level.

Progression of coronary artery calcium in men affected by human immunodeficiency virus infection.

Cardiovascular risk is increased in HIV infected patients. We assessed progression of coronary artery calcium (CAC) in patients with HIV infection to identify factors that may help explain progression of atherosclerosis. Prospective, observational study of 132 HIV-infected men receiving chronic antiretroviral therapy (ART); we measured traditional atherosclerosis risk factors and assessed progression of CAC on sequential 64-slice CT scans at an average interval of 11 months (range 6-36). CAC score progression was defined as absolute and percentage change from baseline. During follow-up 45 patients (34%) showed absolute progression of CAC and 34 of them showed >15% yearly progression, a threshold previously associated with a high risk of myocardial infarction. Age, LDL cholesterol, visceral abdominal fat and current T-helper (CD4+) cell count were significantly associated with absolute CAC progression. Progression of subclinical atherosclerosis in HIV patients is associated with traditional coronary risk factors as well as HIV related factors such as the CD4+ cell count. Therefore, immunologic perturbations secondary to HIV infection may contribute to atherosclerosis progression.

Primary adrenal gland carcinosarcoma associated with metastatic rectal cancer: a hitherto unreported collision tumor.

In this report we describe the case of a young woman with familial adenomatous polyposis who developed metastatic rectal cancer during pregnancy. At diagnosis, we decided to perform a transabdominal laparoscopic adrenalectomy, because of the high risk of bowel obstruction, and to define the origin of the adrenal gland lesion, suspected to be primary on the basis of imaging results. The histological specimen showed a collision tumor between an adrenal metastasis of a rectal tumor and a primary adrenal gland carcinosarcoma. The peculiarity of the case is due not only to its clinical presentation during pregnancy, but also to the presence of this uncommon adrenal collision tumor. A particular challenge for the clinician is to define the priority between these two tumors: the presence of two distinct and colliding aggressive neoplasms poses a problem in the choice of the best therapeutic approach, also given the impossibility to biopsy all metastatic sites. However, we decided to treat the patient as having a metastatic rectal cancer, because we had a solid histological confirmation of metastases.

Role of carcinoembryonic antigen, magnetic resonance imaging, and positron emission tomography-computed tomography in the evaluation of patients with suspected local recurrence of colorectal cancer.

The role of carcinoembryonic antigen (CEA), magnetic resonance imaging (MRI), and positron emission tomography (PET)-computed tomography (CT) in detection of local recurrence of colorectal cancer is evaluated in 71 patients, selected due to suspected relapse at CT follow-up. Recurrence was confirmed by histology in 18 cases and excluded in 25 cases. Sensitivity, specificity, positive and negative predictive values, and accuracy were as follows: 44.4%, 92.5%, 66.7%, 83.1%, and 80.3% for CEA; 88.9%, 73.6%, 53.3%, 95.1%, and 77.5% for MRI; and 94.4%, 73.6%, 54.8%, 97.5%, and 78.9% for PET-CT. A diagnostic protocol integrating CEA and dedicated imaging studies is to be advocated.

Human immunodeficiency virus infection is associated with accelerated atherosclerosis.

OBJECTIVES: Cardiovascular risk is increased in HIV-infected individuals compared with the general population, making HIV disease an ideal model to investigate the pathogenesis and natural history of atherosclerosis. In this pilot study, we compared the progression of coronary artery calcium (CAC) between HIV-infected and uninfected patients. METHODS: Atherosclerosis progression was assessed in 25 HIV-infected men and 13 HIV-negative controls by means of sequential CAC scans using CT. A CAC score progression ≥ 15%/year was used as a surrogate marker of increased risk of cardiovascular events. RESULTS: During a median follow-up of 11 months, a CAC score increase ≥ 15%/year was detected in 14 HIV-infected patients (56%) and 4 HIV-negative individuals (31%). HIV infection, age and hypercholesterolaemia were independently associated with a CAC score increase ≥ 15%/year in an adjusted Cox regression model. CONCLUSIONS: HIV infection, age and hypercholesterolaemia were independently associated with CAC progression. HIV as well as traditional risk factors contribute to accelerate atherosclerosis in HIV-infected patients.

A multicenter randomized study to evaluate intracoronary abciximab with the ClearWay catheter to improve outcomes with Lysis (IC ClearLy): trial study design and rationale.

BACKGROUND: Percutaneous coronary intervention (PCI) is a highly effective therapy for acute ST-elevation myocardial infarction. Adjunctive therapy with platelet glycoprotein (GP) IIb/IIIa inhibitor can result in increased vessel patency and improved outcomes in ST-elevation myocardial infarction patients undergoing PCI. The investigation of novel dosing and delivery strategies of this therapy may help to further improve outcomes. METHODS: IC-Clearly is a randomized, open-label, multicenter trial, with the purpose of evaluating the effectiveness of an intracoronary bolus dose of abciximab delivered using the ClearWay RX catheter vs. an intravenous bolus of abciximab for ST-elevation myocardial infarction with angiographically visible thrombus (thrombus grade >or=2). A total of 150 patients will be randomized 1: 1 to treatment of the culprit artery with intracoronary abciximab (75 patients) or intravenous abciximab (75 patients) in addition to a maintenance infusion regimen of abciximab administered intravenously for 12 h after PCI. The number of patients included in this study is based on the estimation of sample size needed to identify a statistically significant difference in the primary endpoints between the two groups. The primary endpoint chosen to evaluate this hypothesis is infarct size assessed by cardiac magnetic resonance. Clinical outcomes will be assessed for each patient through hospital discharge and at 30-day follow-up. CONCLUSION: The purpose of this study is to evaluate whether an intracoronary bolus of abciximab delivered with the ClearWay RX catheter prior to the 12 h post-PCI intravenous infusion regimen of abciximab will result in significant additional clot resolution in vivo and improved myocardial perfusion when compared with an intravenous bolus of abciximab on top of the 12 h post-PCI intravenous infusion regimen of abciximab as per standard practice. The primary endpoint chosen to evaluate this hypothesis is infarct size as assessed by cardiac magnetic resonance.

Sinus venosus atrial septal defect: the importance of multimodality approach.

A multidisciplinary approach to congenital heart diseases in adults is a primary element for modern medicine. The diagnosis of a sinus venosus atrial septal defect is a typical example of disease that requires the different skills of the cardiologist, cardiac surgeon and radiologist.

Coronary aging in HIV-infected patients.

BACKGROUND: Human immunodeficiency virus (HIV)-infected patients often demonstrate accelerated aging processes. We investigated whether the vascular age of a cohort of stable HIV-infected patients receiving antiretroviral therapy (ART) was increased and sought out predictors of increased vascular age. METHODS: In this cross-sectional study, 400 HIV-infected patients (mean age, 48 years) attending a cardiometabolic clinic underwent cardiac computed tomography imaging to identify coronary artery calcium (CAC). Vascular age was estimated on the basis of the extent of CAC by means of previously published equations. RESULTS: Increased vascular age was observed in 162 patients (40.5%), with an average increase of 15 years (range, 1-43 years) over the chronological age. In univariable analyses, chronological age, male sex, systolic blood pressure, duration of ART, fasting glucose level, fasting serum triglyceride level, total cholesterol level, low-density and high-density lipoprotein cholesterol levels, hypertension, and the presence of the metabolic syndrome were associated with increased vascular age. In multivariable linear regression analyses, current CD4+ cell count was the only predictor of increased vascular age (beta = 0.51; P = .005). CONCLUSIONS: Increased vascular age is frequent among HIV-infected patients and appears to be associated with CD4+ cell count. If these findings were to be confirmed in prospective trials, a positive response to ART with an increase in CD4+ cell count may become a marker of increased risk of atherosclerosis development.

Cardiac delayed enhancement distribution in extralysosomial glycogen storage disease.

We describe magnetic resonance (MR) aspect of cardiac glycogenesis in a 49-years old man, presented a progressively declining cardiac function and negative coronary angiography. Delayed enhancement MR confirmed non-ischemic pattern with unusual diffuse distribution of Gadolinium. Cardiac biopsy revealed a Glycogen Storage Disease, extralysosomial type. Cardiac MR with analysis of delayed enhancement distribution is an emerging tool that can discriminate between ischemic and non-ischemic diseases; however to identify the precise aetiology of a non-ischemic distribution, myocardial biopsy is still needed.

Maximum persisting single lead ST elevation after primary angioplasty: a good predictor of left ventricular dilatation assessed by magnetic resonance imaging.

AIMS: To determine the frequency and predictors of left ventricular dilatation assessed by magnetic resonance imaging among patients with a first acute myocardial infarction treated with successful primary angioplasty and stent. METHODS AND RESULTS: Cine magnetic resonance imaging and late enhancement imaging were prospectively performed in 42 patients 1 month and more than 1 year after successful early reperfusion of a first acute ST elevation myocardial infarction (age 61 +/- 13 years, 76% men, 55% anterior myocardial infarction, and mean symptom-to-balloon time 199 +/- 130 min). Both at the 1-month and at the 15-month magnetic resonance imaging examinations, 57% of patients had left ventricular dilatation (end-systolic volume indexed > 36 ml/m2, values above the upper 95th percentile based on magnetic resonance imaging reference values for left ventricular size in normal participants). The most accurate predictor of left ventricular dilatation was maximum persisting single lead ST elevation 60 min after reperfusion (area under the curve 0.81, P = 0.001). Maximum single lead ST elevation was significantly and independently associated with larger end-systolic volume indexed (beta = 0.35, P = 0.040) after adjusting for muscle and brain isoenzyme of creatine kinase and echocardiographic wall motion score index. CONCLUSION: More than half of patients with a first acute myocardial infarction have left ventricular dilatation despite successful primary coronary angioplasty. Maximum persisting single lead ST elevation 60 min after mechanical reperfusion represents a simple tool for predicting left ventricular dilatation.

Nonalcoholic fatty liver disease in HIV-infected patients referred to a metabolic clinic: prevalence, characteristics, and predictors.

BACKGROUND: The prevalence and predictors of nonalcoholic fatty liver disease (NAFLD) in human immunodeficiency virus (HIV)-infected highly active antiretroviral therapy-experienced patients and the association of NAFLD with risk of cardiovascular disease and subclinical atherosclerosis are unknown. METHODS: We performed a cross-sectional observational study. NAFLD was defined by liver-spleen attenuation values of <1.1 on computed tomography in persons who had neither evidence of chronic viral hepatitis nor a significant history of alcohol consumption. RESULTS: We enrolled 225 patients; 163 (72.4%) were men. Mean (+/-SD) HIV infection duration was 145 +/- 60 months, and mean (+/-SD) body mass index (calculated as weight in kilograms divided by the square of height in meters) was 23.75 +/- 3.59. NAFLD was diagnosed in 83 patients (36.9% of the total cohort). The following variables were significantly associated with NAFLD in univariate analyses: sex, waist circumference, body mass index, cumulative exposure to nucleoside reverse-transcriptase inhibitors, visceral adipose tissue, homeostasis model assessment of insulin resistance index, serum alanine and aspartate aminotransferase levels, and ratios of total serum cholesterol to high-density lipoprotein cholesterol. Coronary artery calcium scores and a diagnosis of diabetes were not associated with NAFLD. In multivariable logistic regression analyses, factors associated (P<0.001) with NAFLD were higher serum alanine to aspartate ratio (odds ratio, 4.59; 95% confidence interval, 2.09-10.08), male sex (odds ratio, 2.49; 95% confidence interval, 1.07-5.81), greater waist circumference (odds ratio, 1.07; 95% confidence interval, 1.03-1.11), and longer nucleoside reverse-transcriptase inhibitor exposure (odds ratio, 1.12 per year of exposure; 95% confidence interval, 1.03-1.22). CONCLUSIONS: NAFLD is common among HIV-infected persons who have the traditional risk factors for NAFLD (elevations in serum alanine level, male sex, and increased waist circumference) apparent. Exposure to nucleoside reverse-transcriptase inhibitors was an independent risk factor for NAFLD, with an 11% increase in the odds ratio for each year of use.
