RESUMEN
BACKGROUND: Septic shock is a severe form of sepsis marked by hypotension with an ominous outcome despite the introduction of modern intensive care. The aim of the present study is to obtain a panel with biomarkers, echocardiographic and vascular parameters to better risk stratify patients and identify those at higher risk of ominous outcome. METHODS: Between May 2013 and April 2016, 35 consecutive patients admitted at the Intensive Care Unit (ICU) of ASST Great Metropolitan Hospital Niguarda with the diagnosis of severe sepsis or septic shock were enrolled. All patients underwent rest echocardiography and several circulating biomarkers of myocardial damage or oxidative stress. RESULTS: The multivariate Cox's proportional hazard model showed that the only independent prognostic predictor for 30-day mortality was the angiopoietin-2, (HR 1.017, 95% CI 1.000-1.034; P = 0.049). An angiopoietin-2 concentrations ≥ of 33,418 pg/mL was identified as the optimal threshold for the discrimination between survivors and non survivors at the time of admission in ICU, with a sensitivity of 80% and a specificity of 68%. CONCLUSIONS: Septic shock has a poor in-hospital outcome even when the best of care is implemented. Among the biochemical parameters angiopoietin was able to identify patients at risk of death. The lowest the value at admission, the highest the risk of in-hospital death. No echocardiographic nor vascular parameter was able to predict outcome in this setting.

BACKGROUND AND AIMS: Metabolic Syndrome (MS) has been related to an impairment in arterial structural and functional properties with heterogeneous results. In this paper we focused on the effects of MS on arterial carotid-femoral PWV and common carotid IMT in two different populations, one of hypertensive patients and one of healthy controls. METHODS AND RESULTS: We enrolled 816 consecutive HT and 536 healthy controls. Vascular structural (IMT) and functional (PWV) properties were evaluated. NCEP-ATP-III criteria were used for diagnosis of MS. MS was diagnosed in 26.9% and 6.9% in hypertensive and control subjects, respectively. PWV was similar in controls with and without MS (7.7 ± 1.9 vs 7.6 ± 1.1 m/s, p = 0.69), while IMT was higher in controls with than those without MS (0.64 ± 0.18 vs 0.57 ± 0.13 mm, p = 0.02). Hypertensives with MS were older (57.9 ± 12.2 vs 52.7 ± 14.1 years, p < 0.001) and showed higher PWV (9.0 ± 2.3 vs 8.4 ± 2.1 m/s, p = 0.001) and IMT (0.72 ± 0.22 vs 0.65 ± 0.17 mm, p < 0.001) than those without MS, however at the age-adjusted analysis only the difference in IMT was confirmed (p = 0.007). Regression models showed that MS was an independent determinant of IMT in both controls (ß = 0.08, p = 0.03) and hypertensives (ß = 0.08, p = 0.01), but not of PWV either in controls (ß = 0.006, p = 0.886 and ß = 0.04, p = 0.19, respectively). CONCLUSIONS: the main finding of our work is that MS is a significant determinant of IMT while this is not the case for PWV. This result have been confirmed both in hypertensive subjects and in healthy controls.

BACKGROUND AND AIM: Heterogeneous results have been obtained in the relationship between Uric Acid (UA) and Target Organ Damage (TOD). In the present study we sought to assess the prevalence of hyperuricemia in healthy subjects as well as the role of UA in determining TOD. We evaluated vascular, cardiac and renal TODs in the whole population as well as sub-grouped by gender. METHODS AND RESULTS: As many as 379 blood donors participated at the present analysis. TOD was evaluated as Pulse Wave Velocity (PWV), Left Ventricular Mass Index (LVMI) and carotid Intima-Media Thickness (IMT). Hyperuricemia was defined with the classic cut-off (>7.0 in men and >6.0 mg/dL in women) but also with a most recently defined one (5.6 mg/dL for both sex). Hyperuricemia was present in 6.3% of the whole population (7.3% males, 2.8% females) considering the classic cut-off, while, with the recently identified one, it was present in 28.2% of the whole population (37.3% males, 4.7% females). Despite all the evaluated TODs significantly correlated with UA, linear multivariate regression analysis showed that none of them, except for GFR, displayed UA as a significant covariate. Similar figures were found also when both correlation and linear regression analyses were repeated in the two genders separately. CONCLUSIONS: Hyperuricemia is an important problem also in healthy subjects and its prevalence could further increase if lower cut-off will be used. In this specific population UA is significantly associated with renal impairment while this was not the case for cardiac and vascular damage.

BACKGROUND AND AIMS: Uric Acid (UA) has been related to the development of Cardio-Vascular (CV) events in patients affected by Chronic Coronary Syndromes (CCS). Among various hypothesis, two arise: UA may negatively act on coronary artery determining a higher degree of atherosclerotic disease, and/or on heart determining a higher prevalence of diastolic dysfunction. Both the above hypothesized effects are object of our investigation. METHODS AND RESULTS: 231 patients who were admitted to the cardiological department of the Niguarda Hospital (Milan, Italy) for CCS from January 2017 to June 2018 were enrolled. Coronary atherosclerotic burden was evaluated from coronary angiography as the number and type of involved vessels, as well as with both Gensini and Syntax scores. All subjects underwent a complete echocardiogram. At unadjusted and adjusted/multivariable analysis, UA levels were not significantly associated with variables analysed from the coronary angiography (number and type of vessels involved, neither the Gensini and Syntax scores) as well as with echocardiographic parameters regarding systolic and diastolic function. CONCLUSIONS: In conclusion, the main finding of our work is the absence of a role for UA in determining coronary arteries disease as well as LV diastolic dysfunction in CCS subjects. Taking together the results of previous studies with ours, we hypothesize that UA could act on heart (both on coronary arteries and on LV function) in an early phase of the disease, whereas while in the advanced stages other factors (previous myocardial infarction, previous myocardial revascularization and so on) may overshadow its effects.

INTRODUCTION: Atherosclerosis causes a chronic reduction of vascularization with consequent impairment of the performance of organs, like the brain or muscles, which determines the functional and cognitive decline of the elderly and their ability to respond to acute stressful condition. Therefore, our aim was to evaluate if ankle brachial index (ABI) could effectively be a determinant of in-hospital functional status and complications in elderly hospitalized patients. METHODS: This is a monocentric cross-sectional study of 189 patients aged 65 years or older. The study was undertaken at the Internal Medicine ward of Niguarda Hospital in Milan. ABI (BOSO ABY-System 100) and in-hospital status (activities of daily living, ADL and instrumental activities of daily living, IADL) were collected on the second day of hospitalization. Complications (falls and delirium episodes) were also recorded during the whole hospitalization period. RESULTS: The average age of patients was 79.3 ± 6.9 years. Among outcomes, only ADL (r = 0.192, p = 0.007) and IADL score (r = 0.200, p = 0.005) showed significant correlation with ABI. Moreover, during the subsequent logistic regression, ABI remained among the statistically significant determinants of both scores (ß = 0.231, p = 0.013 and ß = 0.314, p = 0.001, respectively). CONCLUSIONS: The main result of our study is the finding of ABI as a significant determinant of acute in-hospital functional impairment (evaluated as ADL and IADL scores). The continuous exposure of the brain and muscles to the reduced perfusions induced by vascular atherosclerosis, probably determined the reduced ability to respond to stressful conditions.

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) currently represents the gold standard of treatment for thoracic aortic injury (TAI). Nevertheless, there is an ongoing debate surrounding its safety and subsequent cardiovascular effects. Our aim is to assess heart and vascular structure and function remodeling after TEVAR in TAI young patients. METHODS: We evaluated 20 patients (18 men, age 41 ± 14 years, 11 treated with Gore CTAG, 9 with Medtronic Valiant) with office and 24-hr blood pressure (BP) with specific vascular stiffness analysis (Mobil-O-Graph), aortic diameters (computed tomography scan) and left ventricular mass index (LVMI echocardiogram). Evaluation was done after a median time of 5.0 ± 3.5 years from the trauma. RESULTS: After TAI 12 patients (55%) developed hypertension. When patients were divided according to treating time, those treated for more than 3 years show higher LVMI, PWV, and ascending aorta dilatation. CONCLUSIONS: Our study shows that TEVAR for TAI is associated with heart and vascular remodeling. The presence of TEVAR modifies aortic functional properties and could induce an increase in BP that can promote aortic and cardiac damage, even in young patients.

OBJECTIVE: The role of risk factors on the progression of arterial stiffness has not yet been extensively evaluated. The aim of the current longitudinal study was to evaluate the determinants of the PWV progression over a 4 years follow-up period in hypertensive subjects. MATERIALS AND METHODS: We enrolled 333 consecutive hypertensive outpatients 18-80 aged, followed by the Hypertension Unit of St. Gerardo Hospital (Monza, Italy). At baseline anamnestic, clinical, BP, laboratory data and cfPWV were assessed. We performed a PWV follow-up examination with a median time amounting to 3.75 ± 0.53 years. RESULTS: At baseline the mean age was 54.5 ± 12.6 years, SBP and DBP were 141.3 ± 18.6 and 86.4 ± 10.4 mmHg and PWV was 8.56 ± 1.92 m/s. Despite an improvement in BP control (from 37 to 60%), at follow-up the population showed a PWV increase (ΔPWV 0.87 ± 3.05 m/s). PWV and ΔPWV gradually increased in age decades. In patients with uncontrolled BP values at follow-up ΔPWV showed a greater increase as compared to patients with controlled BP (1.46 ± 3.67 vs 0.62 ± 2.61 m/s, p < .05). The independent predictors of ΔPWV were age, baseline PWV, baseline SBP/MBP and ΔSBP/MBP. CONCLUSIONS: the accelerated arterial aging in treated hypertensive subjects is in large measure explained by age and BP values. PWV changes over time would probably give important information that need further future research studies.

PURPOSE: This study evaluated the incremental value and cost-effectiveness ratio of introducing coronary angiography (CA) with multidetector computed tomography (MDCT-CA) in the diagnostic management of patients with suspected coronary artery disease (CAD) compared with the traditional diagnostic workup. MATERIAL AND METHODS: Five hundred and fifty consecutive patients who underwent MDCT-CA between January 2009 and June 2011 were considered. Patients with atypical chest pain and suspected obstructive CAD were directed to one of two diagnostic pathways: the traditional protocol (examination, stress test, CA) and the current protocol (examination, stress test, MDCT-CA, and CA, if necessary). The costs of each protocol and for the individual method were calculated. Based on the results, the cost-effectiveness ratio of the two diagnostic pathways was compared. A third, modified, diagnostic pathway has been proposed with its relative cost-effectiveness ratio (examination, MDCT-CA, stress test, and CA, if necessary). RESULTS: Stress test vs. MDCT-CA had an accuracy of 66%, a sensitivity and specificity of 21% and 87%, respectively, and a positive (PPV) and negative (NPV) predictive value of 40% and 70%, respectively. Comparison between conventional CA (CCA) and MDCT-CA showed a sensitivity and specificity of 92% and 89%, respectively, a PPV and NPV of 89%, and an accuracy of 92%. The traditional protocol has higher costs than the second protocol: 1,645 euro against 322 euro (mean), but it shows a better cost-effectiveness ratio. The new proposed protocol has lower costs, mean 261 euro, with a better costeffectiveness ratio than the traditional protocol. CONCLUSIONS: The diagnostic protocol for patients with suspected CAD has been modified by the introduction of MDCT-CA. Our study confirms the greater diagnostic performance of MDCT-CA compared with stress test and its similar accuracy to CCA. The use of MDCT-CA to select patients for CCA has a favourable cost-effectiveness profile.

BACKGROUND AND PURPOSE: Radiation Induced Heart Disease (RIHD) represents a late effect of chest irradiation, contributing in increasing mortality rate in oncological patients by affecting pericardium, myocardium, valvs and coronaries. Currently, regarding the risk of Coronary Artery Disease (CAD), a cardiological screening involving exercise stress electrocardiography after 5-10 years from radiotherapy is advised. We sought to determine the rate of ischemia at exercise stress electrocardiography in a population of patients without cardiovascular risk factors who sustained radiotherapy, using a cohort of patients presenting with at least one cardiovascular risk factor as control group. DESIGN AND METHODS: A population of 115 patients who sustained chest irradiation (and associated chemotherapy), presenting without classic cardiovascular risk factors or typical symptoms suggesting CAD, was evaluated with exercise stress electrocardiography. 135 patients with at least one risk factor for cardiovascular disease candidate to stress testing for primary prevention or for atypical symptoms served as control group. RESULTS: The cohort of irradiated patients without classical cardiovascular risk factors is younger (48.7 ± 10.1 vs 60.5 ± 10.8 years, p < 0.001) and presents a lower percentage of males when compared with the control group. In this latter group 25.9% of subjects has diabetes, 62.9% dyslipidaemia, 67.4% hypertension and 19.2% actively smoke. Despite this important differences regarding classic cardiovascular risk factors, no significant differences were found in the number of positive exercise stress electrocardiography (10.4 vs 5.9%, p = ns). CONCLUSIONS: Chest irradiation represents a strong cardiovascular risk factor. In fact, prevalence of positive ECG-stress test is not different (nor higher and nor lower) in irradiated subjects without cardiovascular risk and not irradiated patients with classic cardiovascular risk.

Structural and functional arterial properties commonly impair with aging process. These effects on vasculature could act at many levels from microcirculation to large vessels. Above normal aging process classic cardio-vascular risk factors (hypertension, diabetes mellitus, dyslipidemia, etc.) accelerate the physiological process leading to premature structural and functional alterations that has also been termed early vascular aging. Target organ damage evaluation could be clinically important since these alterations precede by many years' cardiovascular events and so their assessment can predict the onset of more serious and costly events giving the opportunity to prevent CV events by earlier therapeutic intervention. This review will focus on large artery functional properties and particularly on the role of inflammation on the aortic stiffening process.

The role of uric acid (UA) on the arterial stiffness progression has been evaluated only in three studies. Our aim was to evaluate its role as a possible determinant of the pulse wave velocity (PWV) progression over a 3.7 ± 0.5 years follow-up period in hypertensive patients. Specific sex analysis was done due to the well-known sex interaction with UA levels. We enrolled 422 consecutive hypertensive outpatients. At baseline anamnestic, blood pressure (BP) and laboratory data as well as PWV were assessed. PWV was performed again at follow-up examination. Hyperuricemia was defined as a UA > 6 mg/dL for women and > 7 mg/dL for men. Baseline age was 53.2 ± 13 years, 58% were males, systolic and diastolic BP (SBP/DBP) 141.7 ± 17.7/86.8 ± 10.8 mm Hg, UA 5.2 ± 1.4 mg/dL, and PWV 8.5 ± 1.9 m/s. At follow-up, despite better BP values (-8.5 ± 24.6 for SBP and -7.5 ± 15.4 for DBP), PWV increases to 9.1 ± 2.3 m/s (P < 0.001) with mean ΔPWV of+ 0.5 ± 2.2 m/s. A total of 61 patients were hyperuricemic (14.4%), and they present higher PWV baseline (9.0 ± 2.5 vs 8.5 ± 1.8 m/s, P = 0.03) without significant differences in ΔPWV. Hyperuricemic female (6.2%, 11 patients) presents higher baseline PWV without significant differences in ΔPWV. No differences were found in arterial stiffness in hyperuricemic males (20.4%, 50 patients). UA showed association with baseline and ΔPWV in the whole population but it loses statistical significance at the linear regression model. Same figures were also for sex analysis. Our findings provide evidence that baseline UA levels are not determinants of PWV progression over a median follow-up of 3.8 years' in hypertensive patients.

Treatment of overt form of hypertrophic cardiomyopathy (HCM) is often unsuccessful. Efforts are focused on a possible early identification in order to prevent or delaying the development of hypertrophy. Our aim was to find an echocardiographic marker able to distinguish mutation carriers without left ventricular hypertrophy (LVH) from healthy subjects. We evaluated 28 patients, members of eight families. Three types of mutation were recognized: MYBPC3 (five families), MYH7 (two families) and TNNT2 (one family). According to genetic (G) and phenotypic (Ph) features, patients were divided in three groups: Group A (10 patients), mutation carriers with LVH (G+/Ph+); Group B (9 patients), mutation carriers without LVH (G+/Ph-); Group C (9 patients), healthy subjects (G-/Ph-). Echocardiography examination was performed acquiring standard 2D, DTI and 2D-strain imaging. Global longitudinal strain (GLS) and global radial strain (GRS) at basal and mid-level were measured. GRS was significantly different between group B and C at basal level (32.18% ± 9.6 vs. 44.59% ± 12.67 respectively; p-value < 0.0001). In basal posterior and basal inferior segments this difference was particularly evident. ROC curves showed for both the involved segments good AUCs (0.931 and 0.861 for basal posterior and inferior GRS respectively) with the best predictive cut-off for basal posterior GRS at 43.65%, while it was 38.4% for basal inferior GRS. Conversely, GLS values were similar in the three group. 2D longitudinal strain is a valid technique to study HCM. Radial strain and particularly basal posterior and inferior segmental reduction could be able to identify mutation carriers in a pre-clinical phase of disease.

AIMS: Cardio-oncology is imposing as the specialty deputed to the management of a large and rapidly increasing population of cancer patients receiving anticancer treatments with cardiovascular side effects or presenting with cardiac and oncological comorbidities. Organization patterns dramatically vary across Italy. METHODS: On the behalf of ANMCO, we have analyzed the characteristics of cardio-oncology services across different hospital types in Italy. A questionnaire was sent out to all ANMCO divisions inquiring about inner organization, workload, multidisciplinary team and inter-hospital connections. RESULTS: Ninety-eight centers sent back the questionnaire. We summarize different paths into four reference assistance models (sizes XL, L, M and S) according to hospital characteristics, cardio-oncology population size, specialists availability, local facilities and the hospital-surrounding network. We define sizes of the proposed pathways highlighting the need to tailor the model in each single situation. CONCLUSION: No single cardio-oncology organization model can be applied to all hospitals. Each center could select the size/model that best fits its organization. Multidisciplinarity and networking play a crucial role.

OBJECTIVE(S): The eventual role of blood pressure on the endothelial progenitor cell (EPC) has rarely been evaluated and data collected so far relate to patients with co-existing coronary heart disease. METHODS: We have studied the number and functional activity of EPC as well as the number of EPC endothelial colony-forming units (CFU) in a carefully selected group of 36 patients with essential hypertension and 24 normotensive control subjects. RESULTS: In patients with essential hypertension, the EPC number was not statistically different from that found in control subjects (mean +/- SD, essential hypertension 58 +/- 29, controls 53 +/- 20; EPC/high power field). CFU per well were not statistically different in patients with essential hypertension compared with normotensive controls (mean +/- SD, patients with essential hypertension 2.4 +/- 2.6, normotensive controls 3 +/- 3.3 CFU/well). In essential hypertension patients, the EPC number was inversely correlated with both total (R=0.635, P < 0.0001) and low-density lipoprotein (LDL)-cholesterol (R=0.486, P < 0.05). Neither the EPC number nor the EPC CFU were correlated with age, systolic blood pressure, diastolic blood pressure, body mass index, lipoprotein(a), high-sensitivity C-reactive protein or homocysteine. CONCLUSIONS: The present study shows that essential hypertension is not characterized by the altered number or functional activity of EPC. Plasma total and LDL-cholesterol are independent predictors of reduced numbers of circulating EPC in essential hypertension patients. The absence of any correlation between the characteristics of EPC and several markers predictive of cardiovascular damage merits further investigation.

Thrombocytopenia (TP) is a common finding in patients hospitalized for cardiovascular causes and needing antiplatelet and anticoagulant therapies. However, TP is not only a numeric parameter, but mostly a dynamic condition affected by the patients' underlying disorders and concomitant treatments. Platelets are important players in the hemostatic process, taking part to both primary and secondary hemostasis. Although both TP and antithrombotic treatment contribute to the risk of bleeding, the complexity of the pathogenesis of bleeding events makes it difficult to predict them accurately simply based on these two parameters. It should be considered that, under certain clinical conditions, TP may be associated with an increased risk of thrombosis. In order to manage antithrombotic therapies in patients with TP, the frail balance between bleeding and thrombotic complications needs to be estimated. A joint hematological and cardiological evaluation is mandatory in order to avoid stopping an otherwise lifesaving treatment and to decrease the individual patient risk for both thrombotic and/or bleeding events, in each different setting. The purpose of this review is to describe an operative work flow aimed at helping clinicians to face this challenging issue.

OBJECTIVE: Annexin A5 (AnxA5) has been previously linked to the presence of carotid and cardiac target organ damage (TOD) in the context of heart failure and rheumatologic patients. However, information is scant in the context of hypertension. Aim of our study was to evaluate AnxA5 in treated hypertension patients compared with normotensive controls and to determine whether it is associated with vascular and heart TOD evaluated as arterial stiffness, carotid plaque and left ventricular hypertrophy. METHODS: We enrolled 123 consecutive treated hypertension and 124 normotensive controls. TOD was evaluated as pulse wave velocity (PWV, complior), left ventricular hypertrophy (echocardiography) and intima-media thickness and carotid plaque presence (ecographic methods). AnxA5 levels was dosed and compared in patients with and without hypertension and with and without TOD. RESULTS: With similar age hypertension patients showed higher SBP, DBP and AnxA5 levels (13.9â±â11.1 vs 10.1â±â8.4âng/ml, Pâ<â0.001) compared with controls. Regarding TOD hypertension showed higher PWV (8.5â±â1.8 vs 7.6â±â1.5âm/s, Pâ<â0.001) and LVMI (121.7â±â29.3 vs 113.5â±â21.1âg/m, Pâ<â0.05), whereas carotid intima-media thickness was superimposable. AnxA5 correlates with PWV (râ=â0.13, Pâ<â0.05) and DBP (râ=â0.15, Pâ<â0.01), whereas it has never been found as a significant independent predictor of TOD in linear regression analysis. CONCLUSION: Our data have shown that AnxA5 levels are increased in treated hypertension patients. In this condition, it is probably released in the plasma as a defensive mechanism through its anti-inflammatory and anticoagulants effects. We found a significant association with arterial stiffness, but AnxA5 was not found to be a significant predictor of TOD.

AIM: To evaluate modifications of perfusional parameters assessed by perfusion computed tomography (P-CT) of liver metastases (LM) from pancreatic neuroendocrine tumors (PanNETs) during everolimus treatment. PATIENTS AND METHODS: All patients with LMs from G1-2 PanNETs undergoing everolimus treatment between January 2013 and January 2015 were prospectively evaluated with P-CT at baseline, and after 2 and 4 months of therapy. Size, perfusion, blood volume (BV), peak enhancement intensity (PEI) and time to peak for each lesion were calculated. RESULTS: A total of 33 LMs in nine patients with G1-2 PanNETs were prospectively evaluated: 23/33 (69.7%) were responders, 10/33 (30.3%) were non-responders. Among perfusional parameters, only numerical peak enhancement intensity values significantly differed between the two groups at baseline (p=0.043). BV increase was the most significant perfusional modification identifying responding lesions, even at an early stage of treatment, with a high positive predictive value (89.47%). CONCLUSION: P-CT seems to be useful for prediction of response to everolimus of LMs from PanNETs.

INTRODUCTION: Aortic stenosis (AS) is more than only a degenerative disease, it could be also an atherosclerotic-like process involving the valve instead of the vessels. Little is known about the relation of arterial stiffness and AS. AIM: We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI). METHODS: 30 patients with severe AS were treated (15 AVR, 15 TAVI). Before the procedures (t0) and after 1 week (t1) echocardiography and PWV were evaluated. RESULTS: On the whole population, subjects with higher PWV showed higher transvalvular pressure gradient at baseline (mean: 56.5 ± 15.1 vs 45.4 ± 9.5; peak: 93.3 ± 26.4 vs 73.3 ± 14.9, p = 0.02) and, a significantly greater response to the procedures (mean: -42.9 ± 17.2 vs -27.9 ± 10.1, peak: -68.7 ± 29.2 vs -42.8 ± 16.4, p = 0.02). When the two different procedures groups were separated, data were confirmed only in the TAVI subgroup. CONCLUSIONS: In patients undergoing procedures for AS, PWV is correlated with transvalvular gradient and, in TAVI subjects, is able to predict the echocardiographic response. Baseline evaluation of PWV in patients candidates to TAVI can help the selection of subjects, even if larger and longer studies are needed before definitive conclusion can be drawn.

OBJECTIVES: Ga-DOTATOC (Ga) positron emission tomography (PET)/computed tomography (CT) is recommended in the workup of pancreas neuroendocrine tumors (PanNETs); evidence suggests that F-FDG (F) PET/CT can also provide prognostic information. Aims of this study were to assess the role of combined Ga- and F-PET/CT in the evaluation of grade (G) 1-2 PanNETs and to test the correlation between F-PET/CT positivity and tumor grade. METHODS: Preoperative Ga- and F-PET/CT of 35 patients with surgically resected G1-2 PanNETs were evaluated. For grading, the 2010 World Health Organization Classification was used; an ancillary analysis with Ki67 cutoffs at 5% to 20% was conducted. Correlation between F-PET/CT positivity (SUVmax > 3.5) and grade was assessed. RESULTS: Of 35 PanNETs, 28.6% and 71.4% were G1 and G2 as per World Health Organization. Ga-PET/CT showed high sensitivity (94.3%) in detecting G1-2 PanNETs. F-PET/CT was positive in 20% and 76% G1 and G2 tumors (P = 0.002). F-PET/CT identified G2 PanNETs with high positive predictive value (PPV, 90.5%). F-PET/CT correlated with tumor grade also in the ancillary analysis (P = 0.009). CONCLUSIONS: The high sensitivity of Ga-PET/CT in NET detection is known. The high PPV of F-PET/CT in the identification of G2 forms suggests its potential role in PanNETs prognostication and risk stratification.

Radiotherapy for breast cancer may expose heart and vessels to late radiation-induced complications. Although recent technical progress in radiation therapy (RT) has been associated with drastic reduction in cardiovascular (CV) mortality, the prolonged life expectancy of patients with cancer requires CV evaluation for many years. The aim of our study was to evaluate local changes in vascular and cardiac function because of previous breast RT. We enrolled 43 patients treated with RT 15 years ago for breast cancer. CV risk factors and atherosclerotic carotid damage were investigated in all women. We divided patients into 2 groups: R (n = 25) treated to right breast and L (n = 18) to left breast. All subjects were submitted to standard echocardiography and functional arteries evaluation by carotid-radial pulse-wave velocity (crPWV; Complior) and AIx (Sphygmocor; Atcor Medical). Global mean age was 69.5 ± 8 years old. CV risk factors were equally allocated in 2 groups. No patients had history of cardiac or artery disease. R had a significantly increased crPWV (9.9 ± 1.4 vs 8.9 ± 1.1, p = 0.001) on right arm compared with left arm, and in L group, crPWV was similarly higher on the left arm than on right arm (9.6 ± 1.5 vs 8.9 ± 1.4, p = 0.011). AIx was significantly increased in the ipsilateral arm only in L (32.1 ± 7.6 vs 28.3 ± 6.8, p = 0.05). Central blood pressure estimation was not different in the right and left arms. No correlations were found with hormone therapy or chemotherapy. Our data show a local arterial stiffening because of radiation that can be involved in increased CV risk in breast cancer-treated patients.
