Background. We established a dedicated cardiac oncology clinic in 2008 for the rapid diagnosis and treatment of cardiotoxicity related to cancer therapy. In this retrospective observational study, we report on clinical outcomes in women with early-stage breast cancer (EBC) referred to this clinic.Methods. Patients with EBC treated with chemotherapy/trastuzumab and referred between October 2008 and December 2010. Data included patient demographics, staging, cancer treatment/completion, dose delays, left ventricular ejection fraction (LVEF) and cardiac treatment.Results. Forty eight patients: median age 55.5 years, stage I/II disease (77%) and HER-2 positive (98%). The majority of women (n=32) were referred for decreases in LVEF (from baseline). Overall, 37 (77%) patients experienced at least one drop in LVEF while on treatment, of which 22 patients (59%) experienced a ≥10 percentage point drop. The majority of patients (30/37; 81%) experienced declines in LVEF while on trastuzumab. Interventions included trastuzumab delays (n=16/48; 33%) and cardiac medication (12/48: 25%). A total of 81% of patients completed ≥90% of trastuzumab therapy and 15% of patients discontinued therapy due to cardiotoxicity.Conclusion. The majority of patients referred to our clinic completed therapy. Further studies are needed to determine the impact of this multidisciplinary approach on treatment completion and cardiac outcomes.

509 Background: Treatment of HER2-positive breast cancer patients with trastuzumab is highly effective. However, a trastuzumab-associated decline in the left ventricular ejection fraction (LVEF) and clinical heart failure often prompt interruption and discontinuation of treatment. We therefore evaluated the preventive impact of an ACE inhibitor or beta blockers on the left ventricular ejection fraction (LVEF) during treatment of trastuzumab and chemotherapy. Methods: In a prospective randomized study, women with early stage HER2 positive breast cancer undergoing (neo)adjuvant chemotherapy with trastuzumab were randomized to receive either once daily lisinopril (10mg), carvedilol (10mg) or placebo during treatment with trastuzumab and further stratified by anthracycline use (AC+T versus nonAC+T). In a follow up to the initially presented primary endpoint of overall cardiotoxicity, we measured the protective effects of lisinopril or carvedilol to prevent a trastuzumab induced LVEF decrease to less than 50% over the course of therapy as well as the impact on LVEF decrease by >10% within normal LVEF levels. Results: A total of 468 women (mean age was 51±10.7 years) with HER2 overexpressing early-stage breast cancer from 127 community-based oncology practices were enrolled, a prespecified minimum target of 189 (40%) patients were treated with AC+T and 279 (60%) with nonAC+T. Baseline cardiac risk factors of this study population included obesity and an elevated blood pressure. Patients in the anthracycline group were younger and without hypertension. A small, not clinically relevant decrease in LVEF was observed during trastuzumab therapy in all patients which was not significantly altered by any of the cardiac interventions. The rate of LVEF decline to <50% was much more frequent in patients treated with an anthracycline than those with a non-anthracycline containing regimen (21% vs 4.1%). Treatment with lisinopril averted the decline in LVEF in the AC+T group compared to placebo (10.8% vs 30.5%, p=0.045). A smaller but not significant effect was seen by carvedilol. The incidence of cardiotoxicity manifesting as LVEF decrease by ≥10% within the normal range was similar in both AC+T and the nonAC+T arms, and not affected by either lisinopril or carvedilol. Conclusions: In patients treated with trastuzumab without anthracyclines, the impact of trastuzumab on LVEF is small and infrequent. In contrast, patients treated with anthracyclines prior to trastuzumab, demonstrated a decrease in LVEF to below normal levels in a larger than previously reported number of women in this community based setting. The trastuzumab-anthracycline induced decline in LVEF could be prevented with concurrent treatment with lisinopril, which was tolerable even in patients without hypertension.

Abstract Background The CBR3 V244M single nucleotide polymorphism has been linked to the risk of anthracycline-related cardiomyopathy in survivors of childhood cancer. There have been limited prospective studies examining the impact of CBR3 V244M on the risk for anthracycline-related cardiotoxicity in adult cohorts. Objectives This study evaluated the presence of associations between CBR3 V244M genotype status and changes in echocardiographic parameters in breast cancer patients undergoing doxorubicin treatment. Methods We recruited 155 patients with breast cancer receiving treatment with doxorubicin (DOX) at Roswell Park Comprehensive Care Center (Buffalo, NY) to a prospective single arm observational pharmacogenetic study. Patients were genotyped for the CBR3 V244M variant. 92 patients received an echocardiogram at baseline (t0 month) and at 6 months (t6 months) of follow up after DOX treatment. Apical two-chamber and four-chamber echocardiographic images were used to calculate volumes and left ventricular ejection fraction (LVEF) using Simpson’s biplane rule by investigators blinded to all patient data. Volumetric indices were evaluated by normalizing the cardiac volumes to the body surface area (BSA). Results Breast cancer patients with CBR3 GG and AG genotypes both experienced a statistically significant reduction in LVEF at 6 months following initiation of DOX treatment for breast cancer compared with their pre-DOX baseline study. Patients homozygous for the CBR3 V244M G allele (CBR3 V244) exhibited a further statistically significant decrease in LVEF at 6 months following DOX therapy in comparison with patients with heterozygous AG genotype. We found no differences in age, pre-existing cardiac diseases associated with myocardial injury, cumulative DOX dose, or concurrent use of cardioprotective medication between CBR3 genotype groups. Conclusions CBR3 V244M genotype status is associated with changes in echocardiographic parameters suggestive of early anthracycline-related cardiomyopathy in subjects undergoing chemotherapy for breast cancer.

Abstract Background The incidence of cardiotoxicity during cancer therapy is underestimated due to limitations of current diagnostic tests. Current biomarkers (BNP, NT-pro-BNP, hs-Troponin, etc.) and imaging calculations (e.g. echocardiography) such as left ventricular ejection fraction (LVEF) are currently included in the guidelines to designate cardiotoxicity during cancer therapy. Unfortunately, these diagnostics identify systemic damage in symptomatic patients after the heart is unable to compensate for regional dysfunction. Fast-SENC segmental intramyocardial strain (fSENC) is a unique cardiac magnetic resonance imaging (CMR) test that regionally detects subclinical intramyocardial dysfunction in 1 heartbeat. Methods This single center, prospective Prefect Study was used to evaluate cardiotoxicity and the impact of cardioprotective therapy in Breast Cancer and Lymphoma patients (NCT03543228). fSENC was acquired with a 1.5T MRI and processed with the software to quantify intramyocardial strain. Segmental strain was measured in three short axis scans (basal, midventricular, apical) with 16 LV/6 RV longitudinal segments & three long axis scans (2-, 3-, 4-chamber) with 21 LV/5 RV circumferential segments. fSENC CMR was performed before chemotherapy, during and after anthracycline/taxane therapy, at 1 year follow-up, and as needed in between designated follow-up periods. Cardioprotective therapy was offered to patients meeting the definition of cardiotoxicity by the ESC Guidelines on Cardiotoxicity and/or ESMO Clinical Practice Guidelines or those observing a substantial decline in cardiac function. Results Two hundred eight (208) CMRs were performed in fifty-two (52) patients (44 female). Patients had an average (± stdev) age of 53 (15) yrs, BMI of 26 (5) kg/m2; 77% had breast cancer, 23% had Lymphoma. fSENC CMRs required 11 (2) min total exam time. The % of normal fSENC (segmental stain <−17%) with a threshold of 65% showed a sensitivity of 87% and specificity of 89% in detecting cardiotoxicity while echocardiography GLS with a threshold of −17% observed a sensitivity of 20% and specificity of 88%. Figure 1 shows receiver operating characteristic curves for fSENC based on the percent of normal myocardium, and echocardiography global longitudinal strain (GLS) respectively. Global fSENC had substantially lower sensitivity than segmental fSENC despite having higher accuracy than the other global metrics. Figure 1 Conclusion Segmental fSENC intramyocardial strain detects subclinical dysfunction due to cardiotoxic response of chemotherapy before other biomarkers and imaging modalities. The ability to detect the subclinical cardiotoxicity of chemotherapy agents, or other pharmacological agents that cause or worsen heart failure, enables proactive prescription of cardioprotective medications to avoid tissue remodeling that precedes systemic cardiac dysfunction and worsening of global measures such as LVEF and current biomarkers.

PURPOSE: To evaluate the impact of subsequent pregnancy on the prognosis of patients with early breast cancer. PATIENTS AND METHODS: One hundred eight patients who became pregnant after diagnosis of early-stage breast cancer were identified in institutions participating in International Breast Cancer Study Group (IBCSG) studies. Fourteen had relapse of breast cancer before their first subsequent pregnancy. The remaining 94 patients (including eight who relapsed during pregnancy) formed the study group reported here. A comparison group of 188 was obtained by randomly selecting two patients, matched for nodal status, tumor size, age, and year of diagnosis from the IBCSG database, who were free of relapse for at least as long as the time between breast cancer diagnosis and completion of pregnancy for each pregnant patient. Survival comparison used Cox proportional hazards regression models. RESULTS: Overall 5- and 10-year survival percentages (± SE) measured from the diagnosis of early-stage breast cancer among the 94 study group patients were 92% ± 3% and 86% ± 4%, respectively. For the matched comparison group survival was 85% ± 3% at 5 years and 74% ± 4% at 10 years (risk ratio, 0.44; 95% confidence interval, 0.21 to 0.96; P = .04). CONCLUSION: Subsequent pregnancy does not adversely affect the prognosis of early-stage breast cancer. The superior survival seen in this and other controlled series may merely reflect a healthy patient selection bias, but is also consistent with an antitumor effect of the pregnancy.
