Abstract
Monoclonal antibodies, such as trastuzumab and rituximab, significantly contribute to the oncological therapeutic arsenal. However, they may be associated with the development of cardiotoxicity. This study collected data from clinical records of patients in the use of rituximab and trastuzumab in a private oncology clinic from 2017 to 2019. It also investigated cardiovascular adverse drug reactions and associated risk factors. Cardiotoxicity was defined as symptomatic in the presence of signs and symptoms suggestive of heart failure (HF) such as dyspnea, nocturnal cough, and fatigue, among others. Asymptomatic HF was confirmed by the decline in the left ventricular ejection fraction (LVEF) ≥10% of baseline or LVEF ≤50%. Among the 57 patients undergoing trastuzumab, 12 patients (21%) had cardiotoxicity and 8 patients (67%) had extreme or high-risk scores in the cardiotoxicity risk assessment algorithm. Among the 37 patients treated with rituximab, 3 patients (8%) had cardiotoxicity. The presence of previous diabetes mellitus significantly increased the risk of trastuzumab-induced cardiotoxicity (p = 0.02). However, none of the other risk factors influenced the incidence of trastuzumab- and rituximab-induced cardiotoxicity, which the sample size may explain. More studies are needed to investigate the association of risk factors with cardiotoxicity induced by trastuzumab and rituximab, aiming to establish strategies to prevent and manage this effect early.

Abstract
Background Cardiotoxicity remains a dreaded complication for patients undergoing chemotherapy with human epidermal growth factor (HER)-2 receptor antagonists and anthracyclines. Though many studies have looked at racial disparities in heart failure patients, minimal data is present for the cardio-oncology population. Methods We queried the echocardiogram database at a safety net hospital, defined by a high proportion of patients with Medicaid or no insurance, for patients who received HER2 receptor antagonists and/or anthracyclines from January 2016 to December 2018. Patient demographics, clinical characteristics, and treatment outcomes were collected. Based on US census data in 2019, home ZIP codes were used to group patients into quartiles based on median annual household income. The primary end point studied was referral rate to cardiology for patients undergoing chemotherapy. Results We identified 149 patients who had echocardiograms and also underwent treatment with HER2 receptor antagonists and/or anthracyclines, of which 70 (47.0%) were referred to the cardio-oncology program at our institution. Basic demographics were similar, but white patients were more likely to live in ZIP codes with higher income quartiles (p < 0.00001). Comparing between racial groups, there was no statistical difference in the percentage of patients that had a reduction in ejection fraction (EF) (p = 0.75). There was no statistical difference between racial groups in the number of cardiology or oncology appointments attended, number of appointments cancelled, average number of echocardiograms received, additional cardiac imaging received. Black patients were more likely to receive ACEI/ARB post chemotherapy (p = 0.047). A logistic regression model was created using race, age, gender, insurance, income quartile by home ZIP code, comorbidities (hypertension, hyperlipidemia, coronary artery disease, arrhythmia, diabetes mellitus, smoking, family history, age > 65), procedures (coronary stents, cardiac surgery), medications pre-chemotherapy, cancer type, cancer stage, and chemotherapy. This model found that there was an increased referral rate among patients from higher income quartiles (p = 0.017 for quartile 3, p = 0.049 for quartile 4), patients with a history of hypertension (p < 0.0001), and patients with breast cancer (p = 0.02). Conclusions The results of this study suggest that patients of our cardio-oncology population at a safety net hospital receive the same level of surveillance and treatment, and develop drop in ejection fraction at similar rates regardless of their race. However, patients that reside in ZIP codes associated with higher income quartiles, with hypertension, and with breast cancer, are associated with increased rate of referral.

Abstract
BACKGROUND Adjuvant trastuzumab for early-stage (I-III) HER2-positive breast cancer (BC) has led to statistically significant improvement in cancer outcomes but carries a risk of cardiotoxicity. Trastuzumab is discontinued early in many patients for asymptomatic changes in left ventricular ejection fraction. We evaluated the impact of early discontinuation of trastuzumab on cancer outcomes. METHODS We conducted a retrospective population-based cohort study of early BC patients treated with adjuvant trastuzumab in Ontario, Canada, 2007-2016. Four groups were analyzed: group A was full treatment, 17-18 cycles trastuzumab; group B was cardiac event (CE) within treatment period; group C was ≤16 cycles, no CEs, stopped within 30 days from last cardiac imaging; and group D was ≤16 cycles, no CEs, stopped more than 30 days from cardiac imaging. Primary outcome was disease-free survival (DFS); secondary outcomes were: overall survival, cancer-specific mortality, and cardiovascular mortality. Sensitivity analyses were performed 14 months after cycle 1 trastuzumab to control for early relapse. RESULTS A total of 5547 patients met the inclusion criteria: group A = 3921, group B = 309, group C = 362, and group D = 955. The 5-year DFS was 94.1% in group A, 80.1% in group B, 81.4% in group C, and 82.4% in group D. Using a Cox model, the hazard ratio for 5-year DFS was 3.15 (95% confidence interval [CI] = 2.13 to 4.65) for group B, 1.94 (95% CI = 1.30 to 2.89) for group C, and 1.92 (95% CI = 1.46 to 2.53) for group D. Overall, 26 patients (0.5%) died of cardiac causes. CONCLUSIONS BC patients in Ontario who did not complete adjuvant trastuzumab had a statistically significantly higher risk of BC relapse and death and low incidence of cardiac death. These findings support 1 year of adjuvant trastuzumab in early-stage BC.

Abstract
Trastuzumab prolongs progression-free and overall survival in patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer. However, trastuzumab treatment is hampered by cardiotoxicity, defined as a left ventricular ejection fraction (LVEF) decline with a reported incidence ranging from 3 to 27% depending on variable factors. Early identification of patients at increased risk of trastuzumab-induced myocardial damage is of great importance to prevent deterioration to irreversible cardiotoxicity. Although current cardiac monitoring with multi gated acquisition (MUGA) scanning and/or conventional 2D-echocardiography (2DE) have a high availability, their reproducibility are modest, and more sensitive and reliable techniques are needed such as 3D-echocardiography (3DE) and speckle tracking echocardiography (STE). But which other diagnostic imaging modalities are available for patients before and during trastuzumab treatment? In addition, what is the optimal frequency and duration of cardiac monitoring? At last, which biomarker monitoring strategies are currently available for the identification of cardiotoxicity in patients treated with trastuzumab? Current MUGA is not sensitive and reliable enough to detect cardiotoxicity early. 3DE (with STE) is most suitable for cardiac monitoring of patients on trastuzumab. The optimal frequency and duration of cardiac monitoring is not yet established. MPO and hs-troponin are promising biomarkers to detect cardiotoxicity.

Abstract
Background Clinical practice guidelines recommend a multidisciplinary approach to cancer care that brings together all relevant disciplines to discuss optimal disease management. However, the literature is characterized by heterogeneous definitions and few reviews about the processes and outcomes of multidisciplinary care. The objective of this scoping review was to identify and classify the definitions and characteristics of multidisciplinary care, as well as outcomes and interventions for patients with breast cancer. Methods A systematic search for quantitative and qualitative studies about multidisciplinary care for patients with breast cancer was conducted for January 2001 to December 2017 in the following electronic databases: medline, embase, PsycInfo, and cinahl. Two reviewers independently applied our eligibility criteria at level 1 (title/abstract) and level 2 (full-text) screening. Data were extracted and synthesized descriptively. Results The search yielded 9537 unique results, of which 191 were included in the final analysis. Two main types of multidisciplinary care were identified: conferences and clinics. Most studies focused on outcomes of multidisciplinary care that could be variously grouped at the patient, provider, and system levels. Research into processes tended to focus on processes that facilitate implementation: team-working, meeting logistics, infrastructure, quality audit, and barriers and facilitators. Summary Approaches to multidisciplinary care using conferences and clinics are well described. However, studies vary by design, clinical context, patient population, and study outcome. The heterogeneity of the literature, including the patient populations studied, warrants further specification of multidisciplinary care practice and systematic reviews of the processes or contexts that make the implementation and operation of multidisciplinary care effective.

Abstract
Introduction Trastuzumab-related cardiotoxicity has been a major concern in clinical practice, since observational studies have shown higher incidences than that reported in clinical trials. We aim to measure the incidence of trastuzumab-related cardiotoxicity in patients with early and metastatic breast cancer in the south of Brazil. Methods Multicenter prospective observational study, which included 109 patients with early or metastatic HER-2+ breast cancer undergoing any trastuzumab-based regimen. Cardiac events were measured by transthoracic echocardiography assessments and by signs and symptoms of heart failure. Results Trastuzumab-related cardiotoxicity was observed in 58 patients (53.2%). Emergency and hospitalization admissions were necessary in seven and three patients, respectively, due to symptoms of heart failure. One patient died in consequence of trastuzumab-related cardiotoxicity. In total, trastuzumab was discontinued in 31.2% of patients, of which almost a third could not return to treatment. In this study, no risk factors were significantly associated with the development of cardiotoxicity. Discussion The incidence of TRC and trastuzumab's early discontinuation observed was significantly higher in comparison with other studies. These findings endorse the fact that trastuzumab-related cardiotoxicity is a relevant adverse reaction, and therefore, cardiac dysfunction's monitoring must be highlighted in order to allow a safe use of trastuzumab in this population.

Abstract
Cardiotoxicity is the second leading cause of long-term morbidity and mortality among cancer survivors. The purpose of this retrospective observational study is to report on the clinical and cardiac outcomes in patients with early stage and advanced cancer who were referred to our multidisciplinary cardiac oncology clinic (COC). A total of 428 patients were referred to the COC between October 2008 and January 2013. The median age of patients at time of cancer diagnosis was 60. Almost half of patients who received cancer therapy received first-line chemotherapy alone (169, 41.7%), of which 84 (49.7%) were exposed to anthracyclines. The most common reasons for referral to the cardiac oncology clinic were decreased LVEF (34.6%), prechemotherapy assessment (11.9%), and arrhythmia (8.4%). A total of 175 (40.9%) patients referred to the COC were treated with cardiac medications. The majority (331, 77.3%) of patients were alive as of January 2013, and 93 (21.7%) patients were deceased. Through regular review of cardiac oncology clinic referral patterns, management plans, and patient outcomes, we aim to continuously improve delivery of cardiac care to our patient population and optimize cardiac health.

Abstract
PURPOSE OF REVIEW While targeted therapies have improved cancer outcomes, unique cardiovascular toxicities are increasingly recognized, particularly when administered sequentially after anthracyclines or radiation. Patients with cancer therapy-induced cardiotoxicity benefit from collaborative care involving cardiology and oncology, leading to a new interdisciplinary field called cardio-oncology. The present review will highlight contemporary clinical issues in cardio-oncology. RECENT FINDINGS Recently, risk factors for cancer therapy-induced cardiotoxicity have been evaluated in real-world rather than in clinical trial patients. Biomarkers and advanced echocardiography are emerging as sensitive tools for preclinical identification of cancer therapy-induced cardiotoxicity. Single-center studies suggest that cancer therapy-induced cardiotoxicity responds to prompt heart failure medical treatment, and such therapy may even prevent cardiotoxicity. SUMMARY Modern cancer therapy has short-term cardiac risk that may require collaborative management by clinicians with expertise in cardiology and oncology. The increased effectiveness of modern cancer therapy is resulting in a growing population of cancer survivors who are at long-term risk for cardiovascular disease. The present review of contemporary clinical issues in cardio-oncology will be of interest to healthcare providers who manage cardiotoxicity during cancer therapy, and who follow patients who survive cancer but face increased long-term cardiovascular risk.

Abstract
BACKGROUND The use of trastuzumab is associated with an increased survival rate in HER2 positive breast cancer patients. However, it is related to different levels of cardiotoxicity leading to treatment discontinuation, which can deprive patients of the benefits of this therapy. OBJECTIVE This study aimed to identify the incidence of trastuzumab induced cardiotoxicity (TIC) and the rate of discontinuation of trastuzumab in clinical practice. Possible factors associated with TIC were also investigated. SETTING This study was conducted in the General Hospital of the School of Medicine of Ribeirão Preto, University of São Paulo. METHODS We retrospectively reviewed the medical records of patients without distant metastasis that started trastuzumab between 2007 and 2011 in the tertiary hospital. TIC was defined as symptomatic heart failure or a decrease in left ventricular ejection fraction (LVEF) by ≥10 % compared to the first echocardiography measurement or to <50 % at any time. Logistic regression models were used to estimate odds ratios and their respective 95 % confidence intervals for TIC associated with variables such as age, body mass index, smoking history, cardiac risks, type of surgery, presence of positive lymph nodes, chemotherapy regimen and epirubicin cumulative dose. MAIN OUTCOME MEASURE The incidence and factors associated with TIC and the rate of discontinuation of trastuzumab in clinical practice. RESULTS We analyzed the records of 79 patients. TIC developed in 26 (32.9 %) patients, being the LVEF decline by ≥10 % observed in 21 (26.6 %), a decreased to <50 % in four (5.1 %) and one (1.2 %) was symptomatic without LVEF decline. Thirteen (16.4 %) patients discontinued permanently the treatment, three (3.8 %) discontinued temporarily and 10 (12.6 %) finished it without interruption. None of the covariates influenced on the incidence of TIC in this population. CONCLUSION Although most patients finished their treatment, TIC led to trastuzumab discontinuation in a significant proportion of patients suggesting the need of a closer cardiac monitoring. None of the covariates influenced on the incidence of TIC, which can be due to the relatively small sample. Thus, larger scale studies should be conducted in order to establish which specific factors are associated with the development of TIC in order to avoid it.

Abstract
Before the advent of the human epidermal growth factor receptor 2 (HER2)-targeted monoclonal antibody trastuzumab, HER2-positive breast cancers were difficult to treat and had a poor prognosis. Adjuvant trastuzumab is now an important part of the treatment regimen for many women with HER2-positive breast cancer and has undoubtedly resulted in a significant improvement in prognosis, but it is associated with a risk for cardiotoxicity. In this review, we describe the prevalence, patient characteristics, and risk factors for cardiotoxicity associated with use of adjuvant trastuzumab. Understanding risk factors for trastuzumab-induced cardiotoxicity and appropriate patient monitoring during trastuzumab treatment allows for safe and effective use of this important adjuvant therapy.
