Abstract Objective Therapeutic exercise is already used to ameliorate some of the side effects of cancer treatment. Recent studies examined its preventive potential regarding treatment-related toxicity, which can increase the risk of functional decline and lead to disease recurrence and death. This trial will examine whether the ATOPE (Tailored Therapeutic Exercise and Recovery Strategies) program, performed before treatment (ATOPE-B), can mitigate the onset and extent of cardiotoxicity beyond that achieved when the program is followed during treatment (ATOPE-I) in recently diagnosed breast cancer patients. Methods The intervention has a preparatory phase plus 12 to 18 sessions of tailored, high-intensity exercise, and post-exercise recovery strategies. 120 women recently diagnosed with breast cancer, in risk of cardiotoxicity due to anticancer treatment awaiting surgery followed by chemotherapy and/or radiotherapy, will be randomised to either group. In a feasibility study, measurements related to recruitment rate, satisfaction with the program, adherence to them, the retention of subjects, safety, and adverse effects will be explored. In the main trial, the efficacy of these interventions will be examined. The major outcome will be cardiotoxicity, assessed echocardiographically via the left ventricular ejection fraction. Other clinical, physical, anthropometric outcomes, biological and hormonal variables, will be also assessed after diagnosis, after treatment, 1 year after treatment ends, and 3 years after treatment ends. Conclusion Given its potential effect on patient survival, the mitigation of cardiotoxicity is a priority, and physiotherapists have an important role in this mitigation. If the ATOPE-B intervention returns better cardioprotection results, it may be recommendable that patients recently diagnosed follow this program.

BACKGROUND Therapeutic exercise is already much used as a means of ameliorating some of the side effects of cancer treatment. Recent studies have examined its preventive potential with respect to the appearance of treatment-related toxicity. Toxicity-induced cardiac damage - indeed, even temporary adverse effects on the heart - can increase the risk of functional decline, which can in turn lead to disease recurrence and death. OBJECTIVE The present trial will examine whether the ATOPE (Tailored Therapeutic Exercise and Recovery Strategies) program, performed before treatment starts for recently diagnosed breast cancer (ATOPE-B), can mitigate the onset and extent of cardiotoxicity beyond that achieved when the program is followed by similar patients who have already begun treatment (ATOPE-I), using a mobile app, ATOPE+, to determine women’s therapeutic exercise assimilation. METHODS The ATOPE intervention consists of 6 bouts of general preparatory exercise plus 12-18 bouts of tailored, high intensity exercise (whole-body and locoregional exercises), and the following of post-exercise recovery strategies (stretching and breathing exercises). A total of 120 female patients recently diagnosed with stage 1-IIIb breast cancer and awaiting surgery followed by chemotherapy and/or radiotherapy, and at risk of cardiotoxicity as described by the American Society of Clinical Oncology Guidelines, will be randomised 1:1 to either ATOPE-B or ATOPE-I. In a small feasibility study performed before the main trial, and lasting one full cycle of the ATOPE program, measurements related to recruitment rate, satisfaction with the application, satisfaction with the ATOPE-B and ATOPE-I programs, adherence to the program, the retention of subjects, safety, and adverse effects will be explored. In the main trial, which is designed to examine the efficacy of these interventions, the major outcome variable will be cardiotoxicity, assessed echocardiographically via the left ventricular ejection fraction. This, along with other clinical, physical, and anthropometric outcomes, and biological and hormonal variables, will be assessed after diagnosis, 3 days before the third chemotherapy session, 1 year after treatment ends, and 3 years after treatment ends. RESULTS Not aplicable CONCLUSIONS The left ventricular ejection fraction is modified by cancer treatment. Given its potential effect on patient survival, the mitigation of cardiotoxicity is a priority. If the ATOPE-B intervention returns better cardioprotection results than ATOPE-I, it may be recommendable that patients yet to begin treatment for breast cancer, follow this program.

The Impact

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.

Increased Risk

Anthracycline-based regimens with or without anti-human epidermal growth factor receptor (HER) 2 agents such as trastuzumab are effective in breast cancer treatment. Nevertheless, heart failure (HF) has become a significant side effect of these regimens. This study aimed to investigate the incidence and factors associated with HF in breast cancer patients treated with anthracyclines with or without trastuzumab. A retrospective cohort study was performed in patients with breast cancer who were treated with anthracyclines with or without trastuzumab between 1 January 2014 and 31 December 2018. The primary outcome was the incidence of HF. The secondary outcome was the risk factors associated with HF by using the univariable and multivariable cox-proportional hazard model. A total of 475 breast cancer patients were enrolled with a median follow-up time of 2.88 years (interquartile range (IQR), 1.59–3.93). The incidence of HF was 3.2%, corresponding to an incidence rate of 11.1 per 1000 person-years. The increased risk of HF was seen in patients receiving a combination of anthracycline and trastuzumab therapy, patients treated with radiotherapy or palliative-intent chemotherapy, and baseline left ventricular ejection fraction <65%, respectively. There were no statistically significant differences in other risk factors for HF, such as age, cardiovascular comorbidities, and cumulative doxorubicin dose. In conclusion, the incidence of HF was consistently high in patients receiving combination anthracyclines trastuzumab regimens. A reduced baseline left ventricular ejection fraction, radiotherapy, and palliative-intent chemotherapy were associated with an increased risk of HF. Intensive cardiac monitoring in breast cancer patients with an increased risk of HF should be advised to prevent undesired cardiac outcomes.

Purpose The purpose of this analysis was to investigate trastuzumab-associated cardiac adverse effects in breast cancer patients after completion of (neo)adjuvant chemotherapy with or without radiotherapy. Patients and Methods The Herceptin Adjuvant (HERA) trial is a three-group, multicenter, open-label randomized trial that compared 1 or 2 years of trastuzumab given once every 3 weeks with observation in patients with HER-2–positive breast cancer. Only patients who after completion of (neo)adjuvant chemotherapy with or without radiotherapy had normal left ventricular ejection fraction (LVEF ≥ 55%) were eligible. A repeat LVEF assessment was performed in case of cardiac dysfunction. Results Data were available for 1,693 patients randomly assigned to 1 year trastuzumab and 1,693 patients randomly assigned to observation. The incidence of trastuzumab discontinuation due to cardiac disorders was low (4.3%). The incidence of cardiac end points was higher in the trastuzumab group compared with observation (severe congestive heart failure [CHF], 0.60% v 0.00%; symptomatic CHF, 2.15% v 0.12%; confirmed significant LVEF drops, 3.04% v 0.53%). Most patients with cardiac dysfunction recovered in fewer than 6 months. Patients with trastuzumab-associated cardiac dysfunction were treated with higher cumulative doses of doxorubicin (287 mg/m2 v 257 mg/m2) or epirubicin (480 mg/m2 v 422 mg/m2) and had a lower screening LVEF and a higher body mass index. Conclusion Given the clear benefit in disease-free survival, the low incidence of cardiac adverse events, and the suggestion that cardiac dysfunction might be reversible, adjuvant trastuzumab should be considered for treatment of breast cancer patients who fulfill the HERA trial eligibility criteria.

632 Background: Following the BCIRG 001, PACS 01 and HERA trials, this randomised, multicentre, open-label, Phase III trial was designed to demonstrate the benefit of concomitant docetaxel and epirubicin versus anthracyclines, and evaluate the use of sequential trastuzumab. Methods: Patients (pts) with localised, resectable, unilateral breast cancer who met the following criteria were eligible: age <65 years, ≥1 positive node, M0, adequate heart and organ functions. Pts were randomised to receive either 6 cycles of 5-fluorouracil-epirubicin-cyclophosphamide (FEC100: F and C, 500 mg/m2, E 100 mg/m2) (Arm A) or epirubicin-docetaxel (ET75: E 75 mg/m2, T 75 mg/m2) (Arm B). Primary prophylaxis with G-CSF was not planned. Radiotherapy was mandatory after conservative surgery and tamoxifen was required in pts with hormone receptor-positive tumours. Pts with HER2-positive disease were then further randomised to observation only or to 1 year of trastuzumab monotherapy (6 mg/kg iv every 3 weeks). In HER2-positive pts receiving trastuzumab, left ventricular ejection fraction (LVEF) was determined at Cycles 2, 4, 8, 13, 18 and after 2 years. Otherwise, LVEF was determined at baseline and at 1 year post-surgery. Results: Of the 3010 pts recruited (2622 evaluable for safety to date), 1518 received FEC100 and 1492 received ET75 after the first randomisation. Haematologic toxicity was the most frequent toxicity in both arms. Grade 3–4 toxicities were similar for Arms A and B, except febrile neutropenia (10.3% and 31.4%, respectively) and nausea/vomiting (13.2% and 7.5%, respectively). Grade 2 clinical cardiac toxicity (decreased LVEF) was observed in 4 pts in Arm A and 5 in Arm B, with median LVEF scores of 63% in both arms at the end of chemotherapy. HER2-positive pts (n=500) were then randomised to either receive trastuzumab (n=259) or observation only (n=241). Conclusions: These preliminary safety data indicate that FEC100 and ET75 were both well tolerated, with acceptable cardiac safety values. The trial is ongoing and further analysis regarding the use of trastuzumab in this setting will be presented. [Table: see text]

573 Background: The combination of anthracyclines and anti-HER-2 agents is highly active in HER-2 positive breast cancer, but its use is limited by an enhanced risk of cardiac toxicity. We are running a randomized phase II trial of combined preoperative chemotherapy (CT) with anthracycline plus trastuzumab, lapatinib, or both in HER-2 positive stage II-IIIA breast cancer patients. Aims of the study are the percentage of pathological complete response (pCR = breast + axillary nodes) and cardiac safety. We report the updated cardiac safety and activity data following the IDMC recommendation to continue study accrual. Methods: CT consists of sequential paclitaxel (P) 80 mg/m2 weekly for 12 weeks followed by 4 courses of FE75C administered every 3 weeks. Arm A is CT + trastuzumab 2 mg/kg weekly; arm B is CT + lapatinib 1500 mg po daily; arm C is CT + trastuzumab 2 mg/kg weekly + lapatinib 1,000 mg po daily. Both trastuzumab and lapatinib are started concomitantly with the first P administration, and are administered throughout the duration of CT. Left ventricular ejection fraction (LVEF) is evaluated at baseline, before the start of FE75C, and at the completion of treatment. The planned sample size is 120 patients, and has been calculated according to the two steps Simon's design. Results: 53 out of the 120 planned patients have been randomized: 16 in arm A, 17 in arm B, and 20 in arm C. Median age is 48 years (range 27–66). The mean LVEF was 63% (range 54–77%) at baseline, 61% (50–78%) at the completion of weekly P + trastuzumab, lapatinib, or trastuzumab + lapatinib, and 60.3% (54–74%) at the completion of the whole treatment plan. Thirty patients underwent surgery: 19 patients (63%) received breast conserving surgery; 13 patients (43%) achieved a pCR. Conclusions Following the updated interim analysis, the combination of T, L or both with an anthracycline-containing regimen is feasible, with very interesting level of activity. The next planned analysis will be performed when 60 patients will be evaluable and will be presented at the Meeting. [Table: see text]

561 Background: Adjuvant trastuzumab (T)-based chemotherapy has been shown to reduce relapse and improve survival in breast cancer patients but has been associated with increased risks of cardiotoxicity. Our study aims to define the incidence and severity of cardiotoxicity amongst Asian breast cancer patients. Methods: This is a retrospective review of patients who have received adjuvant T from June 2005 to 2007. Cardiotoxicity was defined as a drop in left ventricular ejection fraction (LVEF) to less than 50% and/or reduction of > 10% of baseline. Cardiovascular (CVS) risk factors were defined as having a family history or presence of CAD, hypertension, diabetes mellitus, hyperlipidemia and smoking. We used pair sampled t-test to evaluate the mean LVEF change and Chi-square test to evaluate the association of cardiotoxicity and demographics. Results: There were 179 female patients. Cardiotoxicity was reported in 70 (39.1%), of whom 59 had asymptomatic decline in LVEF and 11 experienced CHF. Mean LVEF, comparing various time points (3, 6, 9 and 12 months) against baseline showed statistically significant decline (p<0.05). T was withheld (n=33) due to asymptomatic decline in LVEF (n=24), symptomatic heart failure (n=4) and both (n=5). Twenty-one with resolution of CHF (n=7) or LVEF recovery (n=14) were rechallenged. Cardiotoxicity recurred in 9 - asymptomatic decline in LVEF (n=8) and recurrent CHF (n=1). There were no cardiac-related deaths. Neither patient demographics nor CVS risk factors predicted for cardiotoxicity. Conclusions: This is one of the largest series reported in Asians receiving T. As previously reported, T-induced cardiotoxicity resulted in mostly asymptomatic reversible decline in LVEF. Our incidence of cardiotoxicity appeared higher (39.1%) in Asians and more importantly, almost half of the patients experienced cardiotoxicity upon rechallenge. It would be prudent to explore whether there is any difference in susceptibility to T-induced cardiotoxicity between the different races.
