Major adverse cardiovascular events are frequently observed in patients undergoing major non-cardiac surgery during the peri-operative period. At this time, the possibility to predict cardiovascular events remains limited, despite the introduction of several algorithms to calculate the risk of adverse events, mainly death and major adverse cardiovascular events (MACE) based on the clinical history, risk factors (sex, age, lipid profile, serum creatinine) and non-invasive cardiac exams (electrocardiogram, echocardiogram, stress tests). The cardiac-specific biomarkers natriuretic peptides (NPs) and cardiac troponins (cTn) have been proposed as additional tools for risk prediction in the peri-operative period, particularly for the identification of myocardial injury in patients undergoing major non-cardiac surgery. The prognostic information from the measurement of BNP/NT-proBNP and hs-cTn is independent and complementary to other important indicators of risk, also including ECG and imaging techniques. Elevated levels of cardiac-specific biomarkers before surgery are associated with a markedly higher risk of MACE during the peri-operative period. BNP/NT-proBNP and hs-cTn should be measured in all patients during the clinical evaluation before surgery, particularly during intermediate- or high-risk surgery, in patients aged65 years and/or with comorbidities. Several questions remain to be assessed in dedicated clinical studies, such as how to optimize the management of patients with raised cardiac specific biomarkers before surgery, and whether a strategy based on biomarker measurement improves patient outcomes and is cost-effective.

Background Severe pneumonia is pathological manifestation of Coronavirus Disease 2019 (COVID-19), however complications have been reported in COVID-19 patients with a worst prognosis. Aim of this study was to evaluate the role of high sensitivity cardiac troponin I (hs-TnI) in patients with SARS-CoV-2 infection. Methods we retrospectively analysed hs-TnI values measured in 523 patients (median age 64 years, 68% men) admitted to a university hospital in Milan, Italy, and diagnosed COVID-19. Results A significant difference in hs-TnI concentrations was found between deceased patients (98 patients) vs discharged (425 patients) [36.05 ng/L IQR 16.5–94.9 vs 6.3 ng/L IQR 2.6–13.9, p

Objectives We aimed to assess the diagnostic performance of CT in patients with a negative first RT-PCR testing and to identify typical features of COVID-19 pneumonia that can guide diagnosis in this case. Methods Patients suspected of COVID-19 with a negative first RT-PCR testing were retrospectively revalued after undergoing CT. CT was reviewed by two radiologists and classified as suspected COVID-19 pneumonia, non-COVID-19 pneumonia or negative. The performance of both first RT-PCR result and CT was evaluated by using sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and area under the curve (AUC) and by using the second RT-PCR test as the reference standard. CT findings for confirmed COVID-19 positive or negative were compared by using the Pearson chi-squared test (P values

Background Few data are available on the rate and characteristics of thromboembolic complications in hospitalized patients with COVID-19. Methods We studied consecutive symptomatic patients with laboratory-proven COVID-19 admitted to a university hospital in Milan, Italy (13.02.2020–10.04.2020). The primary outcome was any thromboembolic complication, including venous thromboembolism (VTE), ischemic stroke, and acute coronary syndrome (ACS)/myocardial infarction (MI). Secondary outcome was overt disseminated intravascular coagulation (DIC). Results We included 388 patients (median age 66 years, 68% men, 16% requiring intensive care [ICU]). Thromboprophylaxis was used in 100% of ICU patients and 75% of those on the general ward. Thromboembolic events occurred in 28 (7.7% of closed cases; 95%CI 5.4%–11.0%), corresponding to a cumulative rate of 21% (27.6% ICU, 6.6% general ward). Half of the thromboembolic events were diagnosed within 24 h of hospital admission. Forty-four patients underwent VTE imaging tests and VTE was confirmed in 16 (36%). Computed tomography pulmonary angiography (CTPA) was performed in 30 patients, corresponding to 7.7% of total, and pulmonary embolism was confirmed in 10 (33% of CTPA). The rate of ischemic stroke and ACS/MI was 2.5% and 1.1%, respectively. Overt DIC was present in 8 (2.2%) patients. Conclusions The high number of arterial and, in particular, venous thromboembolic events diagnosed within 24 h of admission and the high rate of positive VTE imaging tests among the few COVID-19 patients tested suggest that there is an urgent need to improve specific VTE diagnostic strategies and investigate the efficacy and safety of thromboprophylaxis in ambulatory COVID-19 patients., Highlights • COVID-19 is characterized by coagulation activation and endothelial dysfunction. Few data are available on thromboembolic complications. • We studied symptomatic patients with laboratory-proven COVID-19 admitted to a university hospital in Milan, Italy (13.02-10.04.2020). • Venous and arterial thromboembolic events occurred in 8% of hospitalized patients (cumulative rate 21.0%) and 50% of events were diagnosed within 24 h of hospital admission. • Forty-four (11% of total) patients underwent VTE imaging tests; 16 were positive (36% of tests), suggesting underestimation of thromboembolic complications. • There is an urgent need to investigate VTE diagnostic strategies and the impact of thromboprophylaxis in ambulatory COVID-19 patients.

Background: Iron deficiency (ID) is a known co-morbidity and a potential therapeutic target in heart failure. Whether ID is frequent also in ST-segment elevation acute myocardial infarction (STEMI) patients and is associated with worse in-hospital outcomes has never been evaluated. Methods: We defined ID as a serum ferritin < 100 μg/L or transferrin saturation < 20% at hospital admission. We assessed the association between ID and the primary endpoint (a composite of in-hospital mortality and Killip class ≥ 3). We explored the potential association between ID, circulating cell-free mitochondrial DNA (mtDNA), and cardiac magnetic resonance (CMR) parameters. Results: Four-hundred-twenty STEMI patients undergoing primary percutaneous coronary intervention (pPCI) were included. Of them, 237 (56%) had ID. They had significantly higher admission high-sensitivity troponin and mtDNA levels as compared to non-ID patients (145 ± 35 vs. 231 ± 66 ng/L, P < 0.001; 917 [404–1748] vs. 1368 [908–4260] copies/μL; P < 0.003, respectively). A lower incidence of the primary endpoint (10% vs. 18%, P = 0.01) was observed in ID patients (adjusted OR 0.50 [95% CI 0.27–0.93]; P = 0.02). At CMR (n = 192), ID patients had a similar infarct size (21 ± 18 vs. 21 ± 19 g; P = 0.95), but a higher myocardial salvage index (0.56 ± 0.30 vs. 0.43 ± 0.27; P = 0.002), and a smaller microvascular obstruction extent (3.6 ± 2.2 vs. 6.9 ± 3.9 g; P < 0.001). Conclusions: Iron deficiency is frequent in STEMI patients, it is coupled with mitochondrial injury, and, paradoxically, with a better in-hospital outcome. This unexpected clinical result seems to be associated with a smaller myocardial reperfusion injury. The mechanisms underlying our findings and their potential clinical implications warrant further investigation.

Current guidelines recommend pre-therapeutic UGT1A1 genotyping to guide irinotecan dosing, but the usefulness of this approach remains to be clarified. In 247 patients with advanced gastrointestinal cancers undergoing irinotecan-based chemotherapy, we prospectively performed UGT1A1*28 genotyping and we analyzed the incidence of severe neutropenia according to genotype-guided dose reductions. Overall, 28 (11.3%) and 92 (37.2%) patients were homozygous or heterozygous UGT1A1*28 carriers, respectively. Grade ≥ 3 neutropenia was reported in 39% of homozygous patients receiving an upfront dose reduction of irinotecan (median 40%, range 22–58%), in 20% of heterozygous or wild-type patients receiving full dose (ORvs*28/*28 genotype = 0.38; 95% CI: 0.14–1.03; p = 0.058), and in 15.3% of those receiving a reduced dose for clinical reasons (OR vs*28/*28 genotype = 0.28, 95% IC: 0.12–0.67; p = 0.004). Occurrence of severe neutropenia was inversely associated with dose reduction in UGT1A1*28 homozygous carriers (ORx10 unit = 0.62, 95% CI: 0.27–1.40, p = 0.249) and UGT1A1 heterozygous or wild-type patients (ORx10 unit = 0.87, 95% CI: 0.59–1.28, p = 0.478). Incidence of severe neutropenia was related to irinotecan doses and UGT1A1 polymorphisms. Upfront irinotecan dose reductions do not reduce the burden of grade ≥ 3 neutropenia in UGT1A1*28 homozygous carriers.

Biomarker; Liquid biopsy; Machine learning Biomarcadores; Biopsia líquida; Aprendizaje automático Biomarcadors; Biòpsia líquida; Aprenentatge automàtic Despite the strong prognostic stratification of circulating tumor cells (CTCs) enumeration in metastatic breast cancer (MBC), current clinical trials usually do not include a baseline CTCs in their design. This study aimed to generate a classifier for CTCs prognostic simulation in existing datasets for hypothesis generation in patients with MBC. A K-nearest neighbor machine learning algorithm was trained on a pooled dataset comprising 2436 individual MBC patients from the European Pooled Analysis Consortium and the MD Anderson Cancer Center to identify patients likely to have CTCs ≥ 5/7 mL blood (StageIVaggressive vs StageIVindolent). The model had a 65.1% accuracy and its prognostic impact resulted in a hazard ratio (HR) of 1.89 (Simulatedaggressive vs SimulatedindolentP < .001), similar to patients with actual CTCs enumeration (HR 2.76; P < .001). The classifier’s performance was then tested on an independent retrospective database comprising 446 consecutive hormone receptor (HR)-positive HER2-negative MBC patients. The model further stratified clinical subgroups usually considered prognostically homogeneous such as patients with bone-only or liver metastases. Bone-only disease classified as Simulatedaggressive had a significantly worse overall survival (OS; P < .0001), while patients with liver metastases classified as Simulatedindolent had a significantly better prognosis (P < .0001). Consistent results were observed for patients who had undergone CTCs enumeration in the pooled population. The differential prognostic impact of endocrine- (ET) and chemotherapy (CT) was explored across the simulated subgroups. No significant differences were observed between ET and CT in the overall population, both in terms of progression-free survival (PFS) and OS. In contrast, a statistically significant difference, favoring CT over ET was observed among Simulatedaggressive patients (HR: 0.62; P = .030 and HR: 0.60; P = .037, respectively, for PFS and OS). The study was supported by Lynn Sage Cancer Research Foundation and the the CRO Aviano 5x1000 2014 per la Ricerca Sanitaria, Cancer Specific Intramural Grant. The funding sources had no role in the study design, data collection, data analysis, interpretation, or writing of the manuscript.

Background Persistence of antibodies to SARS-CoV-2 viral infection may depend on several factors and may be related to the severity of disease or to the different symptoms. Methods We evaluated the antibody response to SARS-CoV-2 in personnel from 9 healthcare facilities and an international medical school and its association with individuals’ characteristics and COVID-19 symptoms in an observational cohort study. We enrolled 4735 subjects (corresponding to 80% of all personnel) for three time points over a period of 8–10 months. For each participant, we determined the rate of antibody increase or decrease over time in relation to 93 features analyzed in univariate and multivariate analyses through a machine learning approach. Results Here we show in individuals positive for IgG (≥12 AU/mL) at the beginning of the study an increase [p = 0.0002] in antibody response in paucisymptomatic or symptomatic subjects, particularly with loss of taste or smell (anosmia/dysgeusia: OR 2.75, 95% CI 1.753 – 4.301), in a multivariate logistic regression analysis in the first three months. The antibody response persists for at least 8–10 months. Conclusions SARS-CoV-2 infection induces a long lasting antibody response that increases in the first months, particularly in individuals with anosmia/dysgeusia. This may be linked to the lingering of SARS-CoV-2 in the olfactory bulb., Levi and Ubaldi et al. evaluate SARS-CoV-2 seroprevalence in a cohort of 4735 healthcare workers in northern Italy. In seropositive individuals, they show that antibodies are maintained over a period of 8 to 10 months and associate changes in antibody levels over this period with symptoms and specific subgroups of participants., Plain language summary SARS-CoV-2 infection activates the body’s immune system to fight off infection. This immune response results in the production of proteins in the blood that target the virus called antibodies. The extent and duration of this antibody response may be associated with the type of symptoms the infected person is experiencing. Here, we analyzed SARS-CoV-2 antibody levels in individuals with asymptomatic, mild symptomatic (paucisymptomatic) and symptomatic disease in relation to the type of symptoms. We find that the antibody response is higher in people with symptoms and increases in the first three months, particularly in individuals with loss of smell or taste. In all people with SARS-CoV-2 antibodies at the start of the study, levels in the blood last for at least 8–10 months. Hence, SARS-CoV-2 infection is characterized by a long lasting antibody response which may protect from subsequent infections.

To evaluate the significance of HPV persistence as a predictor for the development of CIN2+ recurrence and the impact of multiple genotypes and of HPV 16/18 on recurrence risk. A prospective cohort observational study was carried out at the European Institute of Oncology, Milan, Italy, from December 2006 to December 2014. A total of 408 women surgically treated by excisional procedure for pre-neoplastic and neoplastic cervical lesions were enrolled. HPV test was performed at baseline and at first follow-up visit planned at 6 ± 3 months after treatment. Two-year cumulative incidences for relapse were estimated and compared by the Gray’s test. Overall, 96 (23.5%) patients were persistent for at least one genotype at three to nine months from baseline and 21 (5.1%) patients relapsed. The two-year cumulative relapse incidence was higher in HPV persistent patients compared to not-persistent (CIF = 27.6%, 95% CI: 16.2–40.2% versus CIF = 1.7%, 95% CI: 0.3–5.8%, p &lt, 0.001), in women with persistent multiple infections (CIF = 27.2%, 95% CI: 7.3–52.3%, p &lt, 0.001), and with the persistence of at least one genotype between 16 and 18, irrespective of the presence of other HR genotypes (CIF = 32.7%, 95% CI: 17.9–48.3%, p &lt, 0.001), but not significantly different from women positive for single infections or any other HR genotype, but not for 16 and 18. The risk of CIN2+ recurrence should not be underestimated when same HPV genotype infection persists after treatment.

OBJECTIVES Diagnosis of HPV infection is usually performed from cervical liquid-based cytology specimens (LBC), but these often contain a large amount of human papillomavirus (HPV) genotypes, most of which might cause transient infections. The aim of the study was to evaluate the performance of BD Onclarity HPV test genotyping method on formalin-fixed, paraffin-embedded (FFPE) cervical specimens compared with genotyping results from LBC. MATERIALS AND METHODS Formalin-fixed, paraffin-embedded specimens from women surgically treated for cervical intraepithelial lesions (CINs) at the European Institute of Oncology, Milan, from September 2012 to June 2013 were retrieved from the archives of the Department of Pathology of the European Institute of Oncology. The FFPE and LBC specimens were genotyped using the same extended genotyping Onclarity assay. RESULTS We collected 99 samples (26 CIN 1, 30 CIN 2, and 43 CIN 3+), but 15 were excluded from the analysis: these 84 samples show an overall agreement of 89% for HPV status between FFPE Onclarity samples versus LBC samples. The FFPE and LBC samples showed identical genotype in 75% samples, compatible genotype (at least 1 of the genotypes detected in LBC sample was found in the tissue sample) in 14% specimens, and discrepant genotype in 11% samples. CONCLUSIONS Our data demonstrate a very good concordance between HPV genotypes found in cytological and tissue samples, suggesting that the Onclarity method could also be used to detect HPV in tissue samples and that the HPV genotype detected in FFPE samples is one of the HPV detected in cytological samples, supporting the thesis that one lesion is caused by one HPV genotype.

Lombardy is the Italian region most affected by COVID-19. We tested the presence of plasma anti-SARS-CoV-2 IgG antibodies in 3985 employees across 7 healthcare facilities in areas of Lombardy with different exposure to the SARS-CoV-2 epidemic. Subjects filled a questionnaire to self-report on COVID-19 symptoms, comorbidities, smoking, regular or remote working, and the exposure to COVID-infected individuals. We show that the number of individuals exposed to the virus depended on the geographical location of the facility, ranging between 3 and 43%, consistent with the spatial variation of COVID-19 incidence in Lombardy, and correlated with family interactions. We observed a higher prevalence of females than males positive for IgG, however the level of antibodies was similar, suggesting a comparable magnitude of the anti-spike antibody response. IgG positivity among smokers was lower (7.4% vs 13.5%) although without difference in IgG plasma levels. We observed 11.9% of IgG positive asymptomatic individuals and another 23.1% with one or two symptoms. Interestingly, among the IgG positive population, 81.2% of subjects with anosmia/dysgeusia and fever were SARS-CoV-2 infected, indicating that these symptoms are strongly associated to COVID-19. In conclusion, the frequency of IgG positivity and SARS-CoV-2 infection is dependent on the geographical exposure to the virus and primarily to family rather than hospital exposure.

Supplemental digital content is available in the text., Objective Thirteen human papillomavirus (HPV) genotypes are associated with the highest risk of cervical disease/cancer; however, the risk of disease progression and cancer is genotype dependent. The objective of this systematic review was to examine evidence for high-grade cervical intraepithelial neoplasia (≥CIN 3) risk discrimination using HPV genotyping. Materials and Methods A systematic review of English and non-English articles through MEDLINE, Cochrane, clinicaltrials.gov, and abstracts presented at relevant professional society conferences were searched from 2000 to 2019. Search terms included: cervical cancer screening, HPV genotyping, CIN, HPV persistence, humans, and colposcopy; prospective, controlled trials, observational studies, and retrospective studies of residual specimens; evidence included HPV genotyping (beyond genotypes 16/18/45) results. Data were obtained independently by authors using predefined fields. Risk of bias was evaluated with a modified Newcastle-Ottawa Scale. The Grading of Recommendations, Assessment, Development and Evaluation methodology facilitated overall quality of evidence evaluation for risk estimation. The study protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (CRD42018091093). The primary outcome was CIN 3 or worse risk both at baseline and at different follow-up periods. Results Of 236 identified sources, 60 full texts were retrieved and 16 articles/sources were included. Risk of bias was deemed low; the overall quality of evidence for CIN 3 or worse risk with negative for intraepithelial lesions or malignancies or low-grade squamous intraepithelial cytology was assessed as moderate; that with atypical squamous cells-undetermined significance and “all cytology” was assessed as high. Clinical and methodological heterogeneity precluded meta-analysis. Human papillomavirus genotyping discriminated risk of CIN 3 or worse to a clinically significant degree, regardless of cytology result. Conclusions The evidence supports a clinical utility for HPV genotyping in risk discrimination during cervical cancer screening.

The aim of the study was to investigate the distribution of high-risk (HR) human papillomavirus (HPV) genotypes and the role of multiple infection in preneoplastic and neoplastic cervical lesions, according to histology, age, and the number of genotypes per infection.Nine hundred eighty-eight women affected by known HPV-related cervical lesions and attending the European Institute of Oncology, Milan, Italy, from December 2006 to December 2014, were selected for a cross-sectional study. Prevalence of HPV genotypes was calculated by histology and the number of genotypes per infection. Univariate and multivariable cervical intraepithelial neoplasia (CIN) 2-3 versus CIN 1 risks were estimated by logistic regression models.Overall, HPV 16 (53.1%), HPV 31 (15.1%), and HPV 58 (6.4%) were the most frequent genotypes in precancerous lesions. At multivariable analysis, HPV 16 (p = .02), 18 (p = .013), and 56 (p = .01) were significantly associated to worsen histology, whereas HPV 39 (p = .03) and 45 (p = .03) were statistically correlated only to the increasing number of genotypes per infections. Human papillomavirus 33 was the only genotype significantly related to both the number of genotypes per infection (p = .005) and age (p = .03). Infections by HR-HPV (odds ratio [OR] = 9.48, 95% CI = 3.77-23.8, p.001), HPV genotypes covered by current vaccines (OR = 6.28, 95% CI = 4.05-9.75, p.001), single HPV genotype (OR = 8.13, 95% CI = 4.12-16.0, p.001), as well as age (OR = 1.13, 95% CI = 1.07-1.19, p.001) were significantly associated to higher risk of CIN 2-3.The most of CIN 2+ lesions are sustained by HR-HPV genotypes, especially the ones covered by 9-valent vaccine; therefore, the widespread use of prophylactic HPV vaccines could significantly reduce the incidence of preneoplastic and neoplastic cervical lesions.

Human papillomavirus (HPV) tests differ for technology, targets, and information on the genotype and viral load. In this study, we evaluated the performance of the Seegene Anyplex II HPV HR (Anyplex) assay in the detection of cervical intraepithelial lesions (CIN) and as a test-of-cure in the follow-up after surgical treatment. One hundred and sixty-seven women referred to the European Institute of Oncology, Milan, for surgical treatment of CIN2+ were enrolled. A cervical sample was taken before treatment and at the first follow-up visit: on these samples, Qiagen Hybrid Capture 2 (HC2), Roche Linear Array HPV Test (Linear Array), cytology and histology were performed at baseline, HC2, and cytology at follow-up. Anyplex genotyping HPV test was performed on a post aliquot from liquid-based cytology specimens when available. The concordance between Anyplex and HC2 was 93.6% at baseline and 76.7% at follow-up (3-9 months after treatment), respectively. The concordance between Anyplex and Linear Array was evaluable only at baseline (92.9%). No recurrence occurred in women without the persistence of the same genotype at follow-up. Seven women relapsed: six had persistence of the same genotypes (five HPV16, one HPV33, and one HPV39), while one tested negative not only with Anyplex but also with HC2 for the persistence of low-risk genotype infection (HPV73 only detected by Linear Array). Anyplex test represents a valid option for HPV detection and genotyping in order to stratify women at risk of high-grade lesions at baseline and to monitor patients treated for CIN2+ lesions during follow-up.

Important advances achieved in pharmacological cancer treatment have led progressively to a reduction in mortality from many forms of cancer, and increasing numbers of previously incurable patients can now hope to become cancer-free. Yet, to achieve these improved outcomes a high price has been paid in terms of untoward side effects associated with treatment, cardio-toxicity in particular. Several recent studies have reported that cardiac troponin assay using high-sensitivity methods (hs-cTn) can enable the early detection of myocardial injury related to chemotherapy or abuse of drugs that are potentially cardiotoxic. Several authors have recently suggested that changes in hs-cTn values enable the early diagnosis of cardiac injury from chemotherapy, thus potentially benefitting cancer patients with increased troponin values by initiating early cardioprotective therapy. However, large randomised clinical trials are needed in order to evaluate the cost/benefit ratio of standardised protocols for the early detection of cardiotoxicity using the hs-cTn assay in patients treated with chemotherapy.

Supplemental digital content is available for this article. Direct URL citations appear in the printed text and are provided in the HTML and PDF versions of this article on the journal’s Web site (www.jlgtd.com)., Objective The aim of the study was to examine whether high-grade cervical intraepithelial neoplasia (CIN) was more closely associated with human papillomavirus (HPV) same-genotype persistence (SGTP) versus clearance of prior infection with a subsequent infection by a new genotype (genotype switch [GS]), clearance of HPV infection, or acquisition of a new HPV infection after a negative infection status, during a follow-up testing subsequent to abnormal screening results. Materials and Methods MEDLINE, Cochrane Library, Health Technology Assessment, and clinicaltrials.gov were searched from January 2000 to July 2019 for prospective controlled trials and observational studies of women and retrospective studies using HPV assays with extended- or full-genotype reporting. The primary outcome was high-grade CIN after at least 2 rounds of testing. Overall quality of evidence for the risk estimate outcomes was assessed. Of the 830 identified abstracts, 66 full-text articles were reviewed, and 7 studies were included in the synthesis. The study protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (CRD42018091093). Results Continued HPV-positive women falls in 2 equally large groups: SGTP and GS. Sensitivity, positive predictive value, and positive likelihood ratio of SGTP were significantly higher than for GS. Human papillomavirus genotypes may be ranked into 3 tiers (immediate colposcopy, follow-up testing, return to routine screening), according to associated risk of persistence for high-grade CIN and to prevailing clinical action thresholds. Conclusions There is moderately high-quality evidence to support the clinical utility of SGTP to improve risk discrimination for high-grade CIN compared with qualitative HPV testing without genotype-specific information.

Lombardy is one of the regions in Italy most affected by COVID-19. We assessed the diffusion of the virus via testing plasma anti-SARS-CoV-2 IgG antibodies in 3985 employees of 7 different hospitals, located across the Lombardy region in areas with different exposure to the epidemic. Subjects filled an anamnestic questionnaire to self-report on COVID-19 symptoms, co-morbidities, smoking, regular or smart-working, and the exposure to COVID-19-infected individuals. We show that the number of individuals exposed to the virus depended on the geographical area where the hospital was located and ranged between 3 to 43% which correlated with the incidence of COVID-19 in Lombardy. There was a higher prevalence of females than males positive for IgG, however the level of antibodies was similar, suggesting a comparable magnitude of the response. We observed 10% of IgG positive asymptomatic individuals and another 20% with one or two symptoms. 81% of individuals presenting both anosmia/ageusia and fever resulted SARS-CoV-2 infected. IgG positivity correlated with family contacts.In conclusion, the frequency of IgG positivity and SARS-CoV-2 infection is dependent on the geographical exposure to the virus and to extra-hospital exposure.

Anthracyclines are anti-neoplastic drugs presenting cardiotoxicity as a side effect. Cardiac troponins (cTn) and echocardiography are currently used to assess cardiac damage and dysfunction, but early biomarkers identifying patients in need of preventive treatments remain a partially met need. Circulating microRNAs (miRNAs) represent good candidates, so we investigated their possible roles as predictors of troponin elevation upon anthracycline treatment. Eighty-eight female breast cancer patients administered with doxorubicin (DOX) or epirubicin (EPI) were divided into four groups basing on drug type and cTn positive (cTn+) or negative (cTn&minus, ) levels: DOX cTn&minus, DOX cTn+, EPI cTn&minus, and EPI cTn+. Blood was collected at baseline, during treatment, and at follow-up. We identified plasma miRNAs of interest by OpenArray screening and single assay validation. Our results showed miR-122-5p, miR-499a-5p and miR-885-5p dysregulation in DOX patients at T0, identifying a signature separating, with good accuracy, DOX cTn&minus, from DOX cTn+. No miRNAs showed differential expression in EPI subjects. Conversely, an anthracycline-mediated modulation (regardless of cTn) was observed for miR-34a-5p, -122-5p and -885-5p. Our study indicates specific circulating miRNAs as possible prediction markers for cardiac troponin perturbation upon anthracycline treatment. Indeed, our findings hint at the possible future use of plasma miRNAs to predict the cardiac responsiveness of patients to different anticancer agents.

Objective: This study assessed thyroid function in patients affected by the coronavirus disease-19 (COVID-19), based on the hypothesis that the cytokine storm associated with COVID-19 may influence thyroid function and/or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may directly act on thyroid cells, such as previously demonstrated for SARS-CoV-1 infection. Design and methods: This single-center study was retrospective and consisted in evaluating thyroid function tests and serum interleukin-6 (IL-6) values in 287 consecutive patients (193 males, median age: 66 years, range: 27–92) hospitalized for COVID-19 in non-intensive care units. Results: Fifty-eight patients (20.2%) were found with thyrotoxicosis (overt in 31 cases), 15 (5.2%) with hypothyroidism (overt in only 2 cases), and 214 (74.6%) with normal thyroid function. Serum thyrotropin (TSH) values were inversely correlated with age of patients (rho −0.27; P P P P = 0.09). Conclusions: This study provides first evidence that COVID-19 may be associated with high risk of thyrotoxicosis in relationship with systemic immune activation induced by the SARS-CoV-2 infection.

Background: Chest CT could reduce false negative diagnoses of first RT-PCR tests in patients suspected of COVID-19 We aimed to assess the diagnostic performan

Aims: A multicentre trial, ICOS-ONE, showed increases above the upper limit of normality of cardiac troponin (cTn) in 27% of patients within 12months after the end of cancer chemotherapy (CT) with anthracyclines, whether cardiac protection with enalapril was started at study entry in all (prevention arm) or only upon first occurrence on supra-normal cTn (troponin-triggered arm). The aims of the present post hoc analysis were (i) to assess whether anthracycline-based treatment could induce cardiotoxicity over 36month follow-up and (ii) to describe the time course of three cardiovascular biomarkers (i.e. troponin I cTnI-Ultra, B-type natriuretic peptide BNP, and pentraxin 3 PTX3) and of left ventricular (LV) function up to 36months. Methods and results: Eligible patients were those prescribed first-in-life CT, without evidence of cardiovascular disease, normal cTn, LV ejection fraction (EF) >50%, not on renin-angiotensin aldosterone system antagonists. Patients underwent echocardiography and blood sampling at 24 and 36months. No differences were observed in biomarker concentration between the two study arms, ‘prevention' vs. ‘troponin-triggered'. During additional follow-up 13 more deaths occurred, leading to a total of 23 (9.5%), all due to a non-cardiovascular cause. No new occurrences of LV-dysfunction were reported. Two additional patients were admitted to the hospital for cardiovascular causes, both for acute pulmonary embolism. No first onset of raised cTnI-Ultra was reported in the extended follow-up. BNP remained within normal range: at 36months was 23.4ng/L, higher (N.S.) than at baseline, 17.6ng/L. PTX3 peaked at 5.2ng/mL 1month after CT and returned to baseline values thereafter. cTnI-Ultra peaked at 26ng/L 1month after CT and returned to 3ng/L until the last measurement at 36months. All echocardiographic variables remained stable during follow-up with a median LVEF of 63% and left atrial volume index about 24mL/m2. Conclusions: First-in-life CT with median cumulative dose of anthracyclines of 180mg/m2 does not seem to cause clinically significant cardiac injury, as assessed by circulating biomarkers and echocardiography, in patients aged 51years (median), without pre-existing cardiac disease. This may suggest either a 100% efficacy of enalapril (given as preventive or troponin-triggered) or a reassuringly low absolute cardiovascular risk in this cohort of patients, which may not require intensive cardiologic follow-up.

Background Acute kidney injury (AKI) frequently occurs in several medical and surgical settings, and it is associated with increased morbidity and mortality. In patients undergoing lung cancer surgery, AKI has not been fully investigated. We prospectively evaluated the incidence, clinical relevance, and risk factors of AKI in patients undergoing lung cancer surgery. Moreover, we estimated the accuracy of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the prediction of AKI. Methods Patients undergoing lung cancer surgery were included in the study. Plasma NT-proBNP was measured before and soon after surgery. Postoperative AKI was defined according to the Acute Kidney Injury Network (AKIN) classification. Results A total of 2179 patients were enrolled. Of them, 222 (10%) developed AKI and had a more complicated in-hospital clinical course (overall complication rate: 35% vs. 16%; P Conclusions Acute kidney injury occurs in 10% of patients undergoing lung cancer surgery, and it is associated with a high incidence of postoperative complications. The risk of AKI can be accurately predicted by the combined evaluation of preoperative serum creatinine and NT-proBNP.

Background: High-risk (HR) Human Papilloma Virus (HPV) Tests for HPV detection differ in sensitivity and specificity. In this study, we evaluated the sensitivity and specificity of the HC2 HR HPV Test and the Cobas 4800 HPV Test in consecutive cervical samples collected from a referral population with a high prevalence of disease, using CIN2+ histology as clinical outcome. Methods: Ten thousand two-hundred and thirteen consecutive cervical samples were assayed for HR-HPV in the Laboratory Medicine Division of IEO: 5140 from January 2012 to June 2013 with HC2 and 5073 from July 2013 to December 2014 with the Cobas HPV Test. These two assays differ in terms of target genes and testing methods. Results: The test positivity rates for HC2 and Cobas 4800 were 29.5% (1515/5135, 95% CI 28.3–30.8%) and 23.9% (1212/5069, 95% CI 22.7–25.1%), respectively. The detection rates of CIN2+ in the two time periods were 2.8% (145/5140, 95% CI 2.4–3.3%) and 1.6% (79/5073, 95% CI 1.2–1.9%), respectively. The sensitivity for CIN2+ for HC2 and Cobas 4800 was 95.2% (138/145, 95% CI 91.7–98.7%) and 93.7% (74/79, 95% CI 88.3–99.0%), respectively. The specificity for CIN2+ for HC2 and Cobas 4800 was 72.4% (3613/4990, 95% CI 71.2–73.6%) and 77.2% (3852/4990, 95% CI 76.0–78.4%), respectively. There were 23 cases of cancer in each of the two time periods. HC2 detected 100% (23/23). Cobas 4800 detected 82.6% (19/23). Conclusions: The detection rate of CIN2+ was higher in the first period than in the second period. There was no significant difference in sensitivity of HC2 and Cobas 4800 in women with CIN2+. The specificity of CIN2+ using Cobas 4800 in the second period was higher than HC2 in the first period, probably due to the lower prevalence of CIN2+ in the second period

In Italy, the cohorts of women who were offered Human papillomavirus (HPV) vaccination in 2007/08 will reach the age (25years) for cervical cancer (CC) screening from 2017. The simultaneous shift from cytology-based screening to HPV test-based screening gives the opportunity for unprecedented reorganisation of CC prevention. The ONS (National Screening Monitoring Centre) Directive and the GISCi (Italian Group for Cervical Screening) identified the consensus conference as the most suitable method for addressing this topic. A summary of consensus recommendations is reported here. The main objective was to define the best screening methods in girls vaccinated against HPV and the knowledge required for defining evidence-based screening strategies. A Jury made recommendations about questions and proposals formulated by a panel of experts representative of Italian scientific societies involved in CC prevention and based on systematic reviews of literature and evidence. The Jury considered changing the screening protocols for girls vaccinated in their twelfth year as appropriate. Tailored screening protocols based on vaccination status could be replaced by "one size fits all" protocols only when a herd immunity effect has been reached. Vaccinated women should start screening at age 30, instead of 25, with HPV test. Furthermore, there is a strong rationale for applying longer intervals for re-screening HPV negative women than the currently recommended 5years, but research is needed to determine the optimal screening time points. For non-vaccinated women and for women vaccinated in their fifteenth year or later, the current protocol should be kept.

Objectives Little is known about the epidemiology of human papillomavirus (HPV) in Italy before the age of 25. At the European Institute of Oncology, a prospective observational study on cervical HPV infection in 18-year-old women undergoing quadrivalent HPV vaccination is ongoing. Methods At the first visit before vaccination, all the young women answered an epidemiological questionnaire, and then, the presence of high-risk HPV (hrHPV) was tested. Samples positive for hrHPV were genotyped. Liquid-based cytology was done only to women declaring not to be virgins. Any positivity at cytology or HPV testing was completed with colposcopy and eventually biopsies. Results Seven hundred and thirty women were enrolled. Two hundred sixty-six women were virgins; 7 (2.6%) of these resulted positive to hrHPV: 1 had HPV16 and CP6108, whereas the other 6 resulted negative at genotyping. Of the 464 nonvirgins, 61 (13.1%) were HPV positive: 19 had HPV16, 4 were positive to HPV18 with other hrHPVs, 25 to other hrHPVs, 7 to low-risk HPV, whereas 13 resulted negative at genotyping. HPV positivity was significantly associated to both smoking and having more than 3 partners. Cervical cytology was negative in 433 cases (93.3%), ASC-US in 10 cases (2.2%), low-grade squamous intraepithelial lesion in 20 cases (4.3%), and ASC-H in 1 case (0.2%). No CIN2+ was identified. Conclusions Overall, we found a low positivity to HPV in this population; however, the rate of HPV positivity was significantly related to smoking and sexual life. The cytology result low-grade squamous intraepithelial lesion was more frequent than in the screening population, whereas no CIN2+ was identified, confirming the indication to avoid screening at this age.

Supplemental Digital Content is available in the text., Rationale: In contrast to cardiomyocyte necrosis, which can be quantified by cardiac troponin, functional cardiomyocyte impairment, including mitochondrial dysfunction, has escaped clinical recognition in acute myocardial infarction (AMI) patients. Objective: To investigate the diagnostic accuracy for AMI and prognostic prediction of in-hospital mortality of cytochrome c. Methods and Results: We prospectively assessed cytochrome c serum levels at hospital presentation in 2 cohorts: a diagnostic cohort of patients presenting with suspected AMI and a prognostic cohort of definite AMI patients. Diagnostic accuracy for AMI was the primary diagnostic end point, and prognostic prediction of in-hospital mortality was the primary prognostic end point. Serum cytochrome c had no diagnostic utility for AMI (area under the receiver-operating characteristics curve 0.51; 95% confidence intervals 0.44–0.58; P=0.76). Among 753 AMI patients in the prognostic cohort, cytochrome c was detectable in 280 (37%) patients. These patients had higher in-hospital mortality than patients with nondetectable cytochrome c (6% versus 1%; P

Background: The novel BD OnclarityTM HPV assay (Onclarity) on the BD Viper™ LT system (BD Diagnostics, Sparks, MD), detects E6/E7 DNA from 13 high-risk HPV genotypes and HPV66. We compared the analytical and clinical performance of the Onclarity Assay to that of Hybrid Capture 2 and LINEAR ARRAY using adjudicated histological outcomes from Danish women referred for colposcopy. Methods: 276 women from Copenhagen, Denmark were referred for colposcopy with abnormal cytology and/or a positive HPV test. Two samples for HPV analysis were taken in BD SurePath™ and in the BD cervical brush diluent (CBD) media. ClinicalTrial gov. identifier: NCT01671462, Ethical Approval: H-4-2012-070. Results: Histology was normal in 84 (31%) women, 70 (26%) had CIN1, 47 (17%) CIN2, and 68 (25%) had CIN3. The Onclarity assay detected 67 out of 68 (99%) ≥CIN3 and 113/115 (98%) ≥CIN2. The specificities for

Protein induced by vitamin K absence or antagonist-II (PIVKA-II) has been suggested as a serum biomarker for hepatocellular carcinoma (HCC) in Asian hepatitis B virus (HBV)-treated subjects but no studies tested it in Caucasian cirrhotics long-term nucleos(t)ide analogues (NUCs)-treated. We assessed the detection accuracy of PIVKA-II alone or in combination with alpha-foetoprotein (AFP) in patients under surveillance.This cross-sectional, single centre case-control study was conducted in 212 NUC-treated cirrhotics: 64 HCC and 148 HCC-free controls for 84 (60-107) months. PIVKA-II was determined by a CMIA immunoassay (Abbott; limit of quantification: 8.2 mAU/mL).Protein induced by vitamin K absence or agonist II (PIVKA-II) and AFP levels were significantly higher in HCC patients [Barcelona Clinic Liver Cancer staging system stage 0/A in 91%, diameter 20 (6-50) mm] compared to controls: 109 (17-12 157) vs 31 (13-82) mAU/mL and 5 (1-1163) vs 2 (1-7) ng/mL (P .001 for both markers), with a cut-off of 48 mAU/mL and 4.2 ng/mL by AUROC analysis. The PIVKA-II 82 mAU/mL and AFP 7 ng/mL cut-offs showed 100% specificity, with the former more sensitive (54% vs 42%), accurate (86% vs 83%), with higher negative predictive value (80% vs 76%) compared to AFP for HCC detection. PIVKA-II more frequently than AFP levels exceeded the cut-off 6-18 months before HCC diagnosis. Combining PIVKA-II with AFP increased sensitivity, accuracy and negative predictive values to 67%, 90% and 85%, preserving 100% specificity. PIVKA-II was associated with lesions20 mm or neoplastic thrombosis.Combination of PIVKA-II and AFP increases the detection rate for HCC in NUC-treated HBV Caucasian cirrhotics, a potential new approach for surveillance.

To investigate the clinical performance of a new mRNA-based urine test, aiming to avoid unnecessary follow-up cystoscopy in patients under active surveillance (AS) for recurrent NMIBC. This is a prospective cohort study enrolling patients with history of low-grade (LG) NMIBC, who developed a recurrence during the follow-up and underwent AS. Their urinary samples were analyzed by Xpert BC Monitor (Cepheid, Sunnyvale, CA, USA). The primary endpoint was to investigate if Xpert BC Monitor could avoid unnecessary cystoscopy during the follow-up period. Its sensitivity, specificity, PPVs and NPVs were calculated. A cutoff of 0.4 “linear discriminant analysis” (LDA) was optimized for the AS setting. The cohort consisted of 106 patients with a mean age of 72 ± 9.52 and a median follow-up from AS start of 8.8 (range 0–56.5) months. No statistically significant difference was found for the mean age, smoker status, lesion size, and number of lesions with a cutoff of 0.4. Of 106 patients, 22 (20.8%) were deemed to require treatment because of cystoscopic changes in size and/or number of lesions during the follow-up period. Using a cutoff value of

Background: The heterogeneity of metastatic breast cancer (MBC) necessitates novel biomarkers allowing stratification of patients for treatment selection and drug development. We propose to use the prognostic utility of circulating tumor cells (CTCs) for stratification of patients with stage IV disease. Methods: In a retrospective, pooled analysis of individual patient data from 18 cohorts, including 2436 MBC patients, a CTC threshold of 5 cells per 7.5 ml was used for stratification based on molecular subtypes, disease location, and prior treatments. Patients with >= 5 CTCs were classified as Stage IVaggresive, those with < 5 CTCs as Stage IVindolent. Survival was analyzed using Kaplan-Meier curves and the log rank test. Results: For all patients, Stage IVindolent patients had longer median overall survival than those with Stage IVaggresive (36.3 months vs. 16.0 months, P < 0.0001) and similarly for de novo MBC patients (41.4 months Stage IVindolent vs. 18.7 months Stage IVaggresive p < 0.0001). Moreover, patients with Stage IVindolent disease had significantly longer overall survival across all disease subtypes compared to the aggressive cohort: hormone receptor-positive (44 months vs. 17.3 months, P < 0.0001), HER2-positive (36.7 months vs. 20.4 months, P < 0.0001), and triple negative (23.8 months vs. 9.0 months, P < 0.0001). Similar results were obtained regardless of prior treatment or disease location. Conclusions: We confirm the identification of two subgroups of MBC, Stage IVindolent and Stage IVaggresive, independent of clinical and molecular variables. Thus, CTC count should be considered an important tool for staging of advanced disease and for disease stratification in prospective clinical trials.

Whereas HPV16 and HPV18 have been the focus in current risk‐based cervical cancer screening algorithms using HPV genotype information, mounting evidence suggests that oncogenic HPV types such as HPV31, 33, 52 and 58 pose a ≥CIN3 risk equivalent to or greater than that of HPV18, and the combined risk of HPV31 and HPV33 rivals even HPV16 in women above 30 years of age. Here, we evaluate the baseline risk of CIN2 and CIN3 by genotype in a colposcopy referral population from Denmark and Italy. In total, 655 women were enrolled upon a referral to colposcopy after a positive screening sample. All samples were HPV analyzed using Onclarity HPV assay with extended genotyping and combined with the histology outcomes, a Bayesian probability modeling was used to determine the risk per genotype assessed. The combined data for this referral population showed that the ≥CIN2 risk of HPV16 was 69.1%, HPV31 at 63.3%, HPV33/58 at 52.7%, HPV18 at 46.6% and HPV52 at 40.8%. For ≥CIN3, the risks were 44.3%, 38.5%, 36.8%, 30.9% and 16.8% for HPV16, HPV31, HPV18, HPV33/58 and HPV52, respectively, indicating that the baseline risk of disease arising from HPV16 is, not surprisingly, the highest among the oncogenic HPV genotypes. We find that the HPV genotype‐specific ≥CIN2 and ≥CIN3 risk‐patterns are so distinct that, for example, 35/39/68 and 56/59/66 should be considered only for low intensive follow‐up, thereby proposing active use of this information in triage strategies for screening HPV‐positive women., What's new? Cervical infection with a high‐risk Human Papilloma Virus (HPV) may result in virus persistence and progression to a precancerous lesion and eventually cancer. Primary HPV‐based cervical cancer screening holds promise but requires triage of HPV‐positive samples to reduce overdiagnosis. HPV genotyping has been proposed to be included in triage screening algorithms on the basis of equal risk, equal treatment. Here, the authors present data from a European study showing that risk of CIN2 and ≥CIN3 lesions is genotype‐specific in a colposcopy referral population of women over 30, demonstrating the utility of HPV genotype information in screening.

Objective Many methods are available today for human papillomavirus (HPV) testing; they differ for technology, targets, and information on the genotypes detected. In this study, we evaluated the performance of the Onclarity HPV assay in detection and follow-up of cervical preneoplastic lesions. Materials and Methods One hundred sixty-seven women referred to the European Institute of Oncology, Milan, for treatment of cervical lesions were enrolled. We investigated the utility of Onclarity extended genotyping HPV test in the management of cervical intraepithelial neoplasia (CIN) 2+ preneoplastic lesion. Results At baseline, the concordance was 92% (150/163) between Onclarity and Hybrid Capture 2 (HC2) and 93% (142/152) between Onclarity and linear array, respectively. At follow-up, the concordance between Onclarity and HC2 was 80%. Seven women relapsed: 6 had persistence of the same genotypes and 1 patient tested negative not only with Onclarity but also with HC2 for the presence of a low-risk genotype in the sample. Conclusions This study showed that the evaluation of the HPV genotype persistence may represent a valid option to monitor patients treated for CIN 2+ lesions, because relapses were detected only in patients with persistence of the same genotype detected at baseline

Background: Several biochemical and clinical markers have been proposed for selecting patients for active surveillance (AS). However, some of these are expensive and not easily accessible. Moreover, currently about 30% of patients on AS harbor aggressive disease. Hence, there is an urgent need for other tools to accurately identify patients with low-risk prostate cancer (PCa). Patients: We retrospectively reviewed the medical records of 260 patients who underwent radical prostatectomy and were eligible for AS according to the following criteria: clinical stage T2a or less, prostate-specific antigen level < 10 ng/mL, 2 or fewer cores involved with cancer, Gleason score (GS) ≤6 grade, and prostate-specific antigen density < 0.2 ng/mL/cc. Methods: Univariate and multivariate analyses were performed to evaluate the association of patient and tumor characteristics with reclassification, defined as upstaged (pathological stage >pT2) and upgraded (GS ≥7) disease. A base model (age, prostate-specific antigen, prostate volume, and clinical stage) was compared with models considering neutrophil to lymphocyte ratio (NLR) or platelets to lymphocyte ratio (PLR), monocyte to lymphocyte (MLR), and eosinophil to lymphocyte ratio (ELR). OR and 95% CI were calculated. Finally, a decision curve analysis was performed. Results: Univariate and multivariate analyses showed that NLR, PLR, and ELR upgrading were significantly associated with upgrading (ORs ranging from 2.13 to 4.13), but not with upstaging except for MLR in multivariate analysis, showing a protective effect. Conclusion: Our results showed that NLR, PLR, and ELR are predictors of Gleason upgrading. Therefore, these inexpensive and easily available tests might be useful in the assessment of low-risk PCa, when considering patients for AS.

Acute kidney injury (AKI) frequently occurs in several medical and surgical settings, and it is associated with increased morbidity and mortality. In patients undergoing lung cancer surgery, AKI has not been fully investigated. We prospectively evaluated the incidence, clinical relevance, and risk factors of AKI in patients undergoing lung cancer surgery. Moreover, we estimated the accuracy of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the prediction of AKI.Patients undergoing lung cancer surgery were included in the study. Plasma NT-proBNP was measured before and soon after surgery. Postoperative AKI was defined according to the Acute Kidney Injury Network (AKIN) classification.A total of 2179 patients were enrolled. Of them, 222 (10%) developed AKI and had a more complicated in-hospital clinical course (overall complication rate: 35% vs. 16%; P 0.0001), and a longer hospital stay (10 ± 7 vs. 7 ± 4 days; P 0.0001). The incidence of AKI increased in parallel with the extent of lung resection. Among the independent predictors of AKI, serum creatinine (area under the curve [AUC] 0.70 [95% CI 0.67-0.74]) and NT-proBNP (AUC 0.71 [95% CI 0.67-0.74]) provided the highest predictive accuracy, and their combination further significantly improved AKI prediction (AUC 0.74 [95% CI 0.71-0.77]). No difference in AKI prediction was observed between preoperative and postoperative NT-proBNP (P = 0.84).Acute kidney injury occurs in 10% of patients undergoing lung cancer surgery, and it is associated with a high incidence of postoperative complications. The risk of AKI can be accurately predicted by the combined evaluation of preoperative serum creatinine and NT-proBNP.

Long-term survival of cancer patients can be worsened by cardiovascular morbidity and mortality due to anticancer treatments, based on both traditional and novel anticancer drug-based regimens. The current standard for monitoring cardiac function, based on periodic assessment of left ventricular ejection fraction by transthoracic echocardiography or multi-gated radionuclide angiography, detects cardiotoxicity only when a functional impairment has already occurred, precluding any chance of preventing its development. The limitations of this approach may be surmounted by the use of cardiac biomarkers. Many studies performed both in children and in adults have shown that slight increases in troponins are predictors of further development of cardiac dysfunction. However, other studies failed to find any usefulness in troponin determination. These discrepancies may be due to different times of sampling, lack of standardization, the use of different methods with different sensitivity, and finally not uniformly defined cardiac endpoints. Beyond troponins, the most studied biomarkers in cancer patients treated with potentially cardiotoxic drugs are natriuretic peptides. For them no definite conclusions can be drawn; however, as the findings available in literature show different results. Still, most of data indicate that the persistent increase of BNP or NT-proBNP is associated with the evidence of cardiac dysfunction. Troponin is the gold standard marker for evaluating chemotherapy-induced cardiac injury; BNP and NT-proBNP are hemodynamic indexes. Hence, if we are looking for early myocardial damage during chemotherapy the most useful marker may be troponin; conversely, if we are looking for cardiac dysfunction in asymptomatic long-term cancer survivors, BNP and NT-proBNP are probably the biomarkers of choice.

Analytical and clinical performance validation is essential before introduction of a new human papillomavirus (HPV) assay into clinical practice. This study compares the new BD Onclarity HPV assay, which detects E6/E7 DNA from 14 high-risk HPV types, to the Hybrid Capture II (HC2) HPV DNA test, to concurrent cytology and histology results, in order to evaluate its performance in detecting high-grade cervical lesions. A population of 567 women, including 325 with ≥ASCUS (where ASCUS stands for atypical cells of undetermined significance) and any HC2 result and 242 with both negative cytology and negative HC2 results, were prospectively enrolled for the study. The overall agreement between Onclarity and HC2 was 94.6% (95% confidence intervals [CI], 92.3% to 96.2%). In this population with a high prevalence of disease, the relative sensitivities (versus adjudicated cervical intraepithelial neoplasia grades 2 and 3 [CIN2+] histology endpoints) of the Onclarity and HC2 tests were 95.2% (95% CI, 90.7% to 97.5%) and 96.9% (95% CI, 92.9% to 98.7%), respectively, and the relative specificities were 50.3% (95% CI, 43.2% to 57.4%) for BD and 40.8% (95% CI, 33.9%, 48.1%) for HC2. These results indicate that the BD Onclarity HPV assay has sensitivity comparable to that of the HC2 assay, with a trend to an increased specificity. Moreover, as Onclarity gives the chance to discriminate between the different genotypes, we calculated the genotype prevalence and the absolute risk of CIN2+: HPV 16 was the most prevalent genotype (19.8%) with an absolute risk of CIN2+ of 77.1%.

Background:The assessment of breast cancer (BC) risk is a key step for an effective preventive treatment. Besides the established risk assessment models, validation of independent predictive factors such as circulating biomarkers would improve patient selection and treatment efficacy. Obesity and metabolic imbalance play an important role in BC risk in menopausal women. The role of adipocytes in energy homeostasis is currently under investigation for their emerging relationship with BC. Adipokines (such as leptin and adiponectin) are linked to insulin sensitivity and have been related to BC risk and prognosis. Adiponectin, a peptide hormone secreted by the adipose tissue, has been inversely related to BC risk both in observational studies and in a phase II chemoprevention trial in premenopausal women at increased risk. Aim:We measured baseline serum adiponectin and leptin levels as well as HOMA index, in 534 postmenopausal women enrolled in 16 Italian centers and randomized in one of the two international phase III trials for BC prevention -the IBIS-II(Prevention) and IBIS-II(DCIS) trials- to assess whether these biomarkers were different in the healthy women at increased risk for BC cohort compared to the DCIS cohort. Methods:Healthy postmenopausal women (aged 40-70) at increased risk for BC (on an age-dependent risk model; n=186) or DCIS patients who underwent radical surgery in the previous 6 months (n=348) were eligible according to the two separate protocol entry criteria. At baseline, fasting blood was collected, processed and stored at -80°C till biomarkers measurement. Insulin and glucose levels were measured with the Architect system (Abbott Laboratories, Abbott Park, IL 60064 USA). Serum adiponectin and leptin levels were determined with Immunoassays by R&D (Minneapolis, USA). Results:Participant characteristics and biomarker levels (median, IQ range) by disease status are reported below.

Logistic regression has been used and Odds Ratios (ORs) have been calculated to assess the association of DCIS with biomarkers.DCIS patients were significantly more frequent in the lowest quartile of adiponectin compared to the highest quartile (60% vs 75%; OR=2.49; 95% CI, 1.39-4.44, p= 0.0003) adjusting for center, BMI, HOMA index and age. Conclusions:Low serum adiponectin levels in postmenopausal women are more frequent in DCIS patients compared to healthy at risk subjects independently of BMI, HOMA index and age and results are similar to premenopausal women. Future investigations in both trials will assess whether adiponectin is also associated with BC events. Acknowledgments: J.Forbes and T.Howell, Co-Chairmen,IBIS-II Steering Committee.

Cardiotoxicity is a common complication that may compromise the clinical effectiveness of anticancer therapy. The current standard for monitoring cardiac function detects cardiotoxicity only when a functional impairment has already occurred, not allowing for any early preventive strategy. Areas covered: A novel approach, based on the use of biomarkers has recently emerged, resulting in a very effective tool for early, real-time identification, and monitoring of cardiotoxicity. In particular, cardiac troponin elevation during chemotherapy allows to identify patients more prone to develop myocardial dysfunction and cardiac events. In these patients, use of angiotensin-converting enzyme inhibitors, such as enalapril, has shown to be effective in improving clinical outcomes, giving the chance for cardioprotective strategies in a selected population. The authors reviewed the currently available data about the role of biomarkers in this setting. Expert commentary: Early identification of patients at high risk of cardiotoxicity by cardiac biomarkers - in particular troponin - provides a rationale for targeted preventive strategies against cancer therapy-induced left ventricular dysfunction and its associated clinical complications, with the advantage of limiting prophylactic therapy only to a restricted number of patients. Although the major international oncologic societies encourage this approach, some limitations to a routinely use of biomarkers still exist.

Objective To evaluate, from a gynecology perspective, the transition from cytology-based HPV screening to primary HPV screening. Method Studies examining switching from cytology-based screening to primary HPV-DNA testing with triaging of patients with positive test results were retrieved and reviewed, with a particular focus on screening in an Italian setting. Results The increased complexity of patient-management decisions when implementing HPV-based screening was a critical issue discussed in the literature. The change in strategy represents a paradigm shift in moving from a medical perspective of identifying the disease in individual patients, to a public-healthcare perspective of excluding HPV from the healthy population and identifying a small sub-group of individuals at increased risk of HPV. Conclusion With knowledge about HPV screening evolving rapidly, new programs and related algorithms need to be sufficiently flexible to be adjusted according to ongoing research and the validation of new assays. The establishment of a national working group (including epidemiologists, gynecologists, pathologists, and healthcare providers) will be necessary to properly implement and govern this important technical and cultural transition.

Pancreatic cancer patients underwent surgical resection often present distant metastases early after surgery. Detection of circulating tumor cells (CTCs) has been correlated to a worse oncological outcome in patients with advanced pancreatic cancer. The objective of this pilot study is to investigate the possible prognostic role of CTCs in patients undergoing surgery for pancreatic cancer. In 20 patients undergoing pancreatic resection, 10 mL blood sample was collected intraoperatively from both systemic circulation (SC) and portal vein (PV). Blood sample was analyzed for CTCs with CellSearch® system. All patients underwent an oncologic follow-up for at least 3 years, quarterly. CTCs were detected in nine (45 %) patients: five patients had CTCs in PV only, three patients in both SC and PV, and one patient in SC only. CTC-positive and CTC-negative patients were similar for demographics and cancer stage pattern. No significant differences were found in both overall and disease-free survival between CTC-positive and CTC-negative patients. At 3-year follow-up, portal vein CTC-positive patients presented a higher rate of liver metastases than CTC-negative patients (53 vs. 8 %, p = 0.038). CTCs were found in 45 % of the patients. No correlation between CTCs and survival was found. The presence of CTCs in portal vein has been associated to higher rate of liver metastases after surgery.
