Objective: The impact of mammography screening recall on quality-of-life (QOL) has been studied in women at average risk for breast cancer, but it is unknown whether these effects differ by breast cancer risk level. We used a vignette-based survey to evaluate how women across the spectrum of breast cancer risk perceive the experience of screening recall. Methods: Women participating in mammography or breast MRI screening were recruited to complete a vignette-based survey. Using a numerical rating scale (0-100), women rated QOL for hypothetical scenarios of screening recall, both before and after benign results were known. Lifetime breast cancer risk was calculated using Gail and BRCAPRO risk models. Risk perception, trait anxiety, and breast cancer worry were assessed using validated instruments. Results: The final study cohort included 162 women at low (n = 43, 26%), intermediate (n = 66, 41%), and high-risk (n = 53, 33%). Actual breast cancer risk was not a predictor of QOL for any of the presented scenarios. Across all risk levels, QOL ratings were significantly lower for the period during diagnostic uncertainty compared to after benign results were known (p < 0.05). In multivariable regression analyses, breast cancer worry was a significant predictor of decreased QoL for all screening scenarios while awaiting results, including scenarios with non-invasive imaging alone or with biopsy. High trait anxiety and family history predicted lower QOL scores after receipt of benign test results (p < 0.05). Conclusions: Women with high trait anxiety and family history may particularly benefit from discussions about the risk of recall when choosing a screening regimen. (C) 2020 The Authors.

OBJECTIVE The objective of our study was to compare the supplemental cancer yield and performance of breast MRI in women at higher-than-average risk for breast cancer after negative 2D full-field digital mammography (FFDM) or negative digital breast tomosynthesis (DBT). MATERIALS AND METHODS Retrospective review identified 4418 screening breast MRI examinations: 2291 were performed from January 2010 through January 2012 of patients with a negative FFDM examination in the 12 months before MRI (FFDM group), and 2127 were performed from January 2013 through January 2015 of patients with a negative DBT examination in the 12 months before MRI (DBT group). Screening indications included genetic predisposition, personal history of breast cancer or high-risk lesion, prior chest irradiation, family history, or other risk factors conferring a lifetime risk of greater than 20%. Supplemental cancer detection rate (CDR), abnormal interpretation rate (AIR), and positive predictive values (PPVs) were estimated with 95% exact CIs. Logistic regression analysis, adjusting for differences in patient demographics, was used to compare metrics. RESULTS There was no significant difference in the CDR of MRI in the FFDM group versus the DBT group (11 vs 16 cancers per 1000 examinations, respectively; odds ratio, 1.4; 95% CI, 0.4-1.2; p = 0.23). The AIR, PPV1, PPV2, and PPV3 were 7.4%, 15%, 23%, and 28% for the FFDM group and 7.3%, 22%, 33%, and 35% for the DBT group, with no statistical differences. Of the cancers detected in both groups, the majority were invasive, less than 1 cm, and node-negative. CONCLUSION In women at higher-than-average risk of breast cancer screened with DBT, the supplemental CDR of MRI is similar to that of MRI after FFDM screening, with most cancers being invasive, subcentimeter, and node-negative.

OBJECTIVE. The purpose of this study is to determine both the frequency of repeat CT performed within 1 month after a patient visits the emergency department (ED) and undergoes CT evaluation for abdominal pain and the frequency of worsened or new CT-based diagnoses. SUBJECTS AND METHODS. Secondary analysis was performed on data collected during a prospective multicenter study. The parent study included patients who underwent CT in the ED for abdominal pain between 2012 and 2014, and these patients constituted the study group of the present analysis. The proportion of patients who underwent (in any setting) repeat abdominal CT within 1 month of the index CT examination was calculated. For each of these patients, results of the index and repeat CT scans were compared by an independent panel and categorized as follows: no change (group 1); same process, improved (group 2); same process, worse (group 3); or different process (group 4). The proportion of patients in groups 1 and 2 versus groups 3 and 4 was calculated, and patient and ED physician characteristics were compared. RESULTS. The parent study included 544 patients (246 of whom were men [45%]; mean patient age, 49.4 years). Of those 544 patients, 53 (10%; 95% CI, 7.513%) underwent repeat abdominal CT. Patients' CT comparisons were categorized as follows: group 1 for 43% of patients (23/53), group 2 for 26% (14/53), group 3 for 15% (8/53), and group 4 for 15% (8/53). New or worse findings were present in 30% of patients (16/53) (95% CI, 1944%). When patients with findings in groups 1 and 2 were compared to patients with findings in groups 3 and 4, no significant difference was noted in patient age (p = 0.25) or sex (p = 0.76), the number of days between scans (p = 0.98), and the diagnostic confidence of the ED physician after the index CT scan was obtained (p = 0.33). CONCLUSION. Short-term, repeat abdominal CT was performed for 10% of patients who underwent CT in the ED for abdominal pain, and it yielded new or worse findings for 30% of those patients.

Background: During the development of heart failure (HF), the changes of contraction timing pattern and temporal heterogeneity of segmental contraction happen early and may precede both symptomatic HF and the decrease in left ventricular ejection fraction (LVEF). In patients treated with anthracyclines, both symptomatic HF and the decrease of LVEF are detected once significant myocardial injury has occurred. The aim of the current study was to investigate whether changes in the timing of contraction can be detected early after anthracyclines therapy.Methods: Forty-one women (50 6 11 years old) with newly diagnosed breast cancer were prospectively enrolled in two centers and underwent an echocardiogram before and after anthracyclines. Peak longitudinal myocardial systolic strain was measured on the apical four-and two-chamber views. The time to peak systolic longitudinal strain (TP), ejection time (ET), isovolumic contraction time (IVCT), systolic time, and diastolic time were measured using strain curves and Doppler tracings and compared before and after anthracyclines. The heterogeneity of contraction (dyssynchrony) was measured by the SD of the TP of all segments.Results: Anthracyclines treatment was associated with an increase in heart rate (HR) and a decrease in TP. TP was correlated with HR. TP/ET was independent of HR and inversely correlated to peak strain both at baseline and after anthracyclines. TP/ET increased after anthracyclines (1.26 +/- 0.19 to 1.31 +/- 0.22; P < .001), and this increase was correlated with the decrease in strain. The increase in TP/ET was due to an increase in IVCT/ET. A similar degree of dyssynchrony was found at baseline and after anthracyclines.Conclusions: Anthracyclines treatment induces an increase in the duration of contraction, mainly by increasing the IVCT. This increase is correlated to the decrease in strain and may therefore have additional prognostic value.

OBJECTIVE. The objective of our study was to determine whether specific patient and physician factors--known before CT--are associated with a diagnosis of nonspecific abdominal pain (NSAP) after CT in the emergency department (ED). MATERIALS AND METHODS. We analyzed data originally collected in a prospective multicenter study. In the parent study, we identified ED patients referred to CT for evaluation of abdominal pain. We surveyed their physicians before and after CT to identify changes in leading diagnoses, diagnostic confidence, and admission decisions. In the current study, we conducted a multiple regression analysis to identify whether the following were associated with a post-CT diagnosis of NSAP: patient age; patient sex; physicians' years of experience; physicians' pre-CT diagnostic confidence; and physicians' pre-CT admission decision if CT had not been available. We analyzed patients with and those without a pre-CT diagnosis of NSAP separately. For the sensitivity analysis, we excluded patients with different physicians before and after CT. RESULTS. In total, 544 patients were included: 10% (52/544) with a pre-CT diagnosis of NSAP and 90% (492/544) with a pre-CT diagnosis other than NSAP. The leading diagnoses changed after CT in a large proportion of patients with a pre-CT diagnosis of NSAP (38%, 20/52). In regression analysis, we found that physicians' pre-CT diagnostic confidence was inversely associated with a post-CT diagnosis of NSAP in patients with a pre- CT diagnosis other than NSAP (p = 0.0001). No other associations were significant in both primary and sensitivity analyses. CONCLUSION. With the exception of physicians' pre-CT diagnostic confidence, the factors evaluated were not associated with a post-CT diagnosis of NSAP.

Background: Anthracycline-induced symptomatic heart failure is often irreversible, underlining the usefulness of pretreatment risk assessment. Global longitudinal strain (GLS) before or after chemotherapy is associated with a later decrease in left ventricular ejection fraction (LVEF); however, whether prechemotherapy GLS is associated with symptomatic heart failure and cardiac death in patients treated with anthracyclines is unknown.Methods: Patients with hematologic cancers treated with anthracyclines who underwent prechemotherapy echocardiography between November 2006 and June 2011 were retrospectively recruited. Basic demographic data, end-diastolic and end-systolic left ventricular volumes, LVEF, and GLS were measured. Clinical cardiac events (CEs) were defined as cardiac death or symptomatic heart failure. The association of prechemotherapy parameters with CEs was analyzed using proportional hazard analysis.Results: Over a median follow-up period of 1,593 days (range, 13-2,891 days) after the start of chemotherapy, 28 of 450 patients (6%) experienced CEs. Prechemotherapy LVEF and GLS were lower in patients with CEs compared with those without CEs (58 6 10% vs 62 6 7% [P = .005] and - 15.0 +/- 2.8% vs - 19.7 +/- 2.7% [P < .0001], respectively). Diabetes (hazard ratio [HR], 7.06; P < .0001), hypertension (HR, 2.22; P = .04), LVEF (HR, 0.93; P = .005), and GLS (HR, 1.47; P < .0001) were associated with CEs. After controlling for clinical variables, prechemotherapy GLS remained independently associated with CEs (P < .0001). GLS less than the absolute value of - 17.5% was found in 105 patients (23%) and was associated with a sixfold increase in CEs (P < .0001).Conclusions: Prechemotherapy GLS is an effective tool to stratify patients at high risk for CEs after anthracycline therapy and may help tailor treatments to decrease anthracycline-induced cardiotoxicity.

BACKGROUND:The last decade has seen an increasing prevalence of prophylactic mastectomies with decreasing age of patients treated for breast cancer. Data are limited on the prevalence of histopathologic abnormalities in this population. This study aimed to measure the prevalence of histopathologic findings in contralateral prophylactic mastectomy (CPM) and bilateral prophylactic mastectomy (BPM) patients and identify predictors of findings.METHODS:Our institution's prophylactic mastectomies from 2004 to 2011 were reviewed. Breast specimens with prior malignancies were excluded. Patient factors and pathology reports were collected. Independent predictive factors were identified with univariate and multivariate logistic analysis.RESULTS:A total of 524 specimens in 454 patients were identified. Malignancy was found in 7.0% of CPM and 5.7% of BPM specimens. In CPM patients, ipsilateral lobular carcinoma-in situ [odds ratio (OR) 4.0] and mammogram risk group (OR 2.0) were predictive of malignancy. Age group (OR 1.5), ipsilateral lobular carcinoma-in situ (OR 2.3), and prior bilateral salpingo-oophorectomy (OR 0.3) were predictive of moderate- to high-risk histopathology. Only increasing age group was predictive of increased moderate- to high-risk histopathology in BPM patients (OR 2.3). There were no independent predictors of malignancy in BPM. BRCA status was not predictive in either CPM or BPM.CONCLUSIONS:Patients with lobular carcinoma-in situ in the index breast or high-risk mammograms have a higher prevalence of malignancies. Although BRCA patients may benefit from prophylactic mastectomy, the genetic diagnosis does not increase the prevalence of detecting occult pathology. BPM patients can be counseled about relative risk, where occult pathology increases with age.

AimThe combination of anthracyclines (AC) and trastuzumab (TRZ) is highly effective in patients with aggressive HER-2 + breast cancer, but has a significant risk of cardiotoxicity (CT). Trastuzumab-induced CT may be reversible. The aim of this study was to identify echocardiographic parameters associated with recovery of left ventricular ejection fraction (LVEF) in patients who developed CT after AC and TRZ treatment.Methods and ResultsWomen with newly diagnosed breast cancer treated with AC followed by TRZ and monitored with serial echocardiograms were retrospectively studied. Left ventricular end-diastolic and systolic volumes, LVEF, and global longitudinal strain (GLS) were examined. Development and reversibility of CT were defined based on changes in LVEF according to the 2014 ASE/EACVI recommendations. Cox analysis was used to determine the association of echocardiographic variables with the subsequent development and reversibility of CT. Ninety-five patients underwent 5 echocardiograms or more in a 17-month (13-28 months) follow-up period. Nineteen patients (20%) developed CT. Left ventricular volumes, LVEF, and GLS measured after AC completion identified the subsequent development of CT. Of the 19 patients with CT, the LVEF partially or fully recovered in 13 (68%). GLS at the time of CT diagnosis was associated with subsequent recovery of LVEF (P = 0.004).ConclusionIn patients with breast cancer treated with AC and TRZ who develop CT, GLS at the time of CT diagnosis is associated with subsequent recovery of LVEF and may be useful for risk stratification and to guide treatment.

AIMSThe aim of this study was to investigate the reproducibility of intravascular optical coherence tomography (IVOCT) assessments, including a comparison to intravascular ultrasound (IVUS). Intra-observer and inter-observer variabilities of IVOCT have been previously described, whereas inter-institute reliability in multiple laboratories has never been systematically studied.METHODS AND RESULTSIn 2 independent laboratories with intravascular imaging expertise, 100 randomized matched data sets of IVOCT and IVUS images were analysed by 4 independent observers according to published consensus document definitions. Intra-observer, inter-observer, and inter-institute variabilities of IVOCT qualitative and quantitative measurements vs. IVUS measurements were assessed. Minor inter- and intra-observer variability of both imaging techniques was observed for detailed qualitative and geometric analysis, except for inter-observer mixed plaque identification on IVUS (κ = 0.70) and for inter-observer fibrous cap thickness measurement reproducibility on IVOCT (ICC = 0.48). The magnitude of inter-institute measurement differences for IVOCT was statistically significantly less than that for IVUS concerning lumen cross-sectional area (CSA), maximum and minimum lumen diameters, stent CSA, and maximum and minimum stent diameters (P < 0.001, P < 0.001, P < 0.001, P = 0.02, P < 0.001, and P = 0.01, respectively). Minor inter-institute measurement variabilities using both techniques were also found for plaque identification.CONCLUSIONIn the measurement of lumen CSA, maximum and minimum lumen diameters, stent CSA, and maximum and minimum stent diameters by analysts from two different laboratories, reproducibility of IVOCT was more consistent than that of IVUS.

Anthracyclines are an important component of cancer treatments; however, their use is limited by the occurrence of cardiotoxicity. There are limited data on the occurrence of heart failure and the value of baseline and follow-up measurements of left ventricular (LV) ejection fraction (EF) in the current era. Therefore, the objectives of the present study were twofold: (1) to characterize the occurrence of and risk factors for major adverse cardiac events (MACEs: symptomatic heart failure and cardiac death) in a large contemporaneous population of adult patients treated with anthracyclines and (2) to test the value of LVEF and LV dimensions obtained using echocardiography in the prediction of MACE. Five thousand fifty-seven patients were studied, of whom 124 (2.4%) developed MACE. Of the total cohort, 2,285 patients had an available echocardiogram pre-chemotherapy. Patients with MACE were older (p <0.0001), predominantly men (p = 0.03), and with a higher incidence of cardiovascular risk factors and cardiac treatments. Patients with hematologic cancers had a higher incidence of cardiac events than patients with breast cancer (4.2% vs 0.7%, p <0.0001). Baseline LVEF, LVEF <= 5 points above the lower limits of normal, and LV internal diameter were predictive of the rate of occurrence of MACE. In conclusion, older patients with hematologic cancers and patients with a baseline LVEF <= 5 points above the lower limit of normal have higher incidence of MACE and should be closely monitored.

AIMS:The aim of this study was to assess whether baseline echocardiographic measures of left ventricular (LV) size and function predict the development of symptomatic heart failure or cardiac death (major adverse cardiac events, MACE) in patients treated with anthracyclines who have a pre-chemotherapy left ventricular ejection fraction (LVEF) between 50 and 59%.METHODS AND RESULTS:Patients with an LVEF between 50 and 59% before anthracyclines were selected. In these patients, LV volumes, LVEF, and peak longitudinal strain (GLS) were measured. Individuals were followed for MACE and all-cause mortality over a median of 659 days (range: 3-3704 days). Of 2234 patients undergoing echocardiography for pre-anthracycline assessment, 158 (7%) had a resting ejection fraction of 50-59%. Their average LV end-diastolic volume (LVEDV) was 101 ± 22 mL, LVEF was 54 ± 3%, and global longitudinal strain (GLS) was -17.7 ± 2.6%. Twelve patients experienced a MACE (congestive heart failure) at a median of 173 days (range: 15-530). Age, diabetes, previous coronary artery disease, LVEDV, indexed LVEDV, LVESV, indexed LVESV, and GLS were all predictive of MACE (P = 0.012, 0.039, 0.0029, 0.012, and 0.0065 for LVEDV, LVEDVI, LVESV, LVESVI, and GLS, respectively). Indexed LVEDV and GLS remained predictive of MACE when adjusted for age. Age and GLS were also predictive of overall mortality (P < 0.0001 and 0.0105, respectively).CONCLUSION:In patients treated with anthracyclines with an LVEF of 50-59%, both baseline EDV and GLS predict the occurrence of MACE. These parameters may help target patients who could benefit from closer cardiac surveillance and earlier initiation of cardioprotective medical therapy.

OBJECTIVE Successful management of a contrast reaction requires prompt recognition and treatment and effective team dynamics among radiologists, technologists, and nurses. A radiology department implemented a simulation program in which teams of nurses, technologists, and physicians managed simulated contrast reactions. The purpose of this study was to evaluate whether simulation improved the participants' abilities to manage a contrast reaction and work in a team during an emergency. SUBJECTS AND METHODS Physicians, nurses, and technologists worked in inter-professional teams to manage two high-fidelity simulated adverse contrast reactions. Participants completed surveys before and after the simulation that included knowledge-based questions about the appropriate management of contrast reactions. Surveys also included questions for assessing participants' perceptions of their ability to manage adverse contrast reactions, measured with a 6-point Likert scale. Before and after comparisons were made with the McNemar test with a Bonferroni correction requiring p ≤ 0.003 for significance. For the other analyses, p ≤ 0.05 was considered significant. RESULTS After completion of the simulation exercises, participants had significant improvement in knowledge (p < 0.001). After the simulation, participants reported significant improvement in their ability to manage an anaphylactoid reaction and their ability to work in a team (p < 0.00001). Participants requested repeat simulation exercises every 6-12 months. CONCLUSION Simulation exercises improved the self-reported ability of radiology personnel to manage contrast reactions and work in a team during an emergency. Simulation should be incorporated into future educational initiatives to improve patient safety in radiology practices.

BACKGROUND:Biomarkers may play an important role in identifying patients at risk for cancer therapy cardiotoxicity. Our objectives were to define the patterns of change in biomarkers with cancer therapy and their associations with cardiotoxicity.METHODS:In a multicenter cohort of 78 breast cancer patients undergoing doxorubicin and trastuzumab therapy, 8 biomarkers were evaluated at baseline and every 3 months over a maximum follow-up of 15 months. These biomarkers, hypothesized to be mechanistically relevant to cardiotoxicity, included high-sensitivity cardiac troponin I (hs-cTnI), high-sensitivity C-reactive protein (hsCRP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), growth differentiation factor 15 (GDF-15), myeloperoxidase (MPO), placental growth factor (PlGF), soluble fms-like tyrosine kinase receptor-1 (sFlt-1), and galectin 3 (gal-3). We determined if biomarker increases were associated with cardiotoxicity at the same visit and the subsequent visit over the entire course of therapy. Cardiotoxicity was defined by the Cardiac Review and Evaluation Criteria; alternative definitions were also considered.RESULTS:Across the entire cohort, all biomarkers except NT-proBNP and gal-3 demonstrated increases by 3 months; these increases persisted for GDF-15, PlGF, and hs-cTnI at 15 months. Increases in MPO, PlGF, and GDF-15 were associated with cardiotoxicity at the same visit [MPO hazard ratio 1.38 (95% CI 1.10-1.71), P = 0.02; PlGF 3.78 (1.30-11.0), P = 0.047; GDF-15 1.71 (1.15-2.55), P = 0.01] and the subsequent visit. MPO was robust to alternative outcome definitions.CONCLUSIONS:Increases in MPO are associated with cardiotoxicity over the entire course of doxorubicin and trastuzumab therapy. Assessment with PlGF and GDF-15 may also be of value. These findings motivate validation studies in additional cohorts.

Objectives The aim of this study was to determine if individual or multiple biomarkers are associated with cardiotoxicity in patients with breast cancer undergoing cancer therapy.Background Current methods to identify patients at risk for cardiotoxicity from cancer therapy are inadequate.Methods We measured 8 biomarkers in a multicenter cohort of 78 patients with breast cancer undergoing doxorubicin and trastuzumab therapy: ultrasensitive troponin I (TnI), high-sensitivity C-reactive protein (CRP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), growth differentiation factor (GDF)-15, myeloperoxidase (MPO), placental growth factor (PlGF), soluble fms-like tyrosine kinase receptor (sFlt)-1, and galectin (gal)-3. Cardiotoxicity, defined by the Cardiac Review and Evaluation Committee criteria, was assessed every 3 months for up to 15 months. Hazard ratios (HRs) of cardiotoxicity risk were assessed for each biomarker at baseline, at visit 2 (3 months), and as a function of the difference between visit 2 and baseline. Joint models were assessed for the most promising biomarkers.Results TnI, CRP, GDF-15, MPO, PlGF, and sFlt-1 levels increased from baseline to visit 2 (p < 0.05). A greater risk of cardiotoxicity was associated with interval changes in TnI (HR: 1.38 per SD; 95% confidence interval: 1.05 to 1.81; p = 0.02) and MPO (HR: 1.34 per SD; 95% confidence interval: 1.00 to 1.80; p = 0.048) and in models combining both markers (p = 0.007 and p = 0.03, respectively). The risk of cardiotoxicity was 46.5% in patients with the largest changes in both markers (DTnI > 121.8 mg/l; DMPO > 422.6 pmol/l).Conclusions Early increases in TnI and MPO levels offer additive information about the risk of cardiotoxicity in patients undergoing doxorubicin and trastuzumab therapy. Independent validation of these findings is necessary before application to clinical practice. (C) 2014 by the American College of Cardiology Foundation

162 Background: Understanding hepatocellular cancer (HCC) tumor growth patterns is important for determining optimal treatment strategy. However, growth of untreated HCC tumors is unclear and prior studies are limited by older imaging technologies and small samples. We evaluated HCC growth patterns and predictors in a cohort of patients with serial modern computed tomography (CT) and magnetic resonance imaging (MRI). Methods: Two radiologists retrospectively evaluated CT and MRI imaging for 56 patients with 83 HCC tumors with at least two images. Tumor Volume (TV) = 4/3* π *average short axis (X)*average long axis (Y)*X. To assess the relative change in size, normalized tumor volume (NTV) = TV/ baseline TV. Growth curves were fitted using an exponential growth model for tumor >2 observations. Univariate analysis explored clinical and pathologic predictors of NTV. A multivariate model was built by backward elimination of significant univariate variables. Results: Among 56 patients: 77% male, 96% cirrhotic, 50% Child-Pugh Class (CPC) B, 59% Hepatitis C, 32% obese, 37% diabetic, and 12% used metformin. Mean baseline and end TV were 98.8 cm3 and 213.0 cm3, respectively. Mean follow-up=8.3 months and mean number of serial images=3. Exponential TV growth was observed on visual inspection. Diabetes predicted lower NTV (i.e. slower TV growth) in univariate and multivariate analysis (Table). Obesity decreased the impact of diabetes. Conclusions: Diabetic patients had slower growing tumors than non-diabetics, even when clinical and pathologic factors were controlled. Tumor growth fit an exponential pattern. Further study of the impact of metabolic conditions on HCC tumor growth may provide insights into growth factors and identify potential treatment targets. [Table: see text]
