152 Background: Trastuzumab is widely used in Her2 positive metastatic esophageal and gastric cancers along with chemotherapy. Cardiotoxicity of trastuzumab has been described precisely in Her2 positive breast cancers and occurs with asymptomatic lowering of LVEF (Left Ventricular Ejection Fraction) in up to 10% of cases. Esogastric cancer patients are usually older and have more comorbidities than patients followed for breast cancer. Methods: This monocentric retrospective study measured the incidence of symptomatic and asymptomatic cardiotoxicity in patients treated for metastatic esogastric cancers and its potential impact regarding overall survival from October 2009 to September 2015. Patients should receive trastuzumab with chemotherapy during the period of study for treatment of Her2 positive metastatic esogastric cancer as first-line chemotherapy. Results: 27 patients received trastuzumab along with chemotherapy during the period of study. Median age was 62.3 years, sex ratio 21 M/6 W. The median number of cycles of trastuzumab was 5 cycles. The asymptomatic cardiotoxicity rate, defined by a drop of more than 10% of LVEF between the enrollment echocardiogram and the third month treatment echocardiogram, was of 22%. Symptomatic cardiotoxicity was observed in two patients (7.4%), with one cardiac failure and one myocardial infarction, with no associated death. Cardiovascular comorbidities and cardiac irradiation which is recurrent in this indication did not appear as a predictive factor of cardiotoxicity (p = 1). Overall survival of patients was not statistically modified by the occurring of cardiotoxicity even if we noted a trend to better outcome of the patients presenting an asymptomatic LVEF lowering. Conclusions: This study is to our knowledge the first to focus specifically on the cardiotoxicity of trastuzumab in esogastric metastatic Her2 positive cancer in the real world. These patients seem to be at a higher asymptomatic cardiac risk than breast cancer patients. However cardiovascular comorbidities didn’t appear as predictive factors of trastuzumab induced cardiotoxicity and should not prevent patient from benefiting of this treatment.

e11555 Background: The infusion rate is considered to affect incidence and severity of infusion reaction (IR) caused by infusion of protein formulations. Trastuzumab (TRS) is approved for 90-minute infusion as the initial dose followed by 30-minute infusion with 250 ml saline. We evaluated the safety of TRS intravenously administered over 30minutes with 100 ml saline to reduce burden of patients although safety of infusion with 250 ml saline is established. Methods: Women with HER2 positive breast cancer, ≥18 years and ≥55% left ventricular ejection fraction (LVEF) were registered in the study. Patients received 8mg/kg of TRS 250 ml over 90 minutes diluted in 250 ml saline followed by 6mg/kg of TRS in 100 ml saline over 30 minutes in a three-week cycle. The primary endpoint of this study was the incidence of infusion reactions, and secondary endpoints were as follows: incidence of adverse events and effects on cardiac function. Results: Between June 2011 and June 2012, a total of 31 patients were recruited; 24 for adjuvant therapy and seven with metastases. The median age was 59 years (range, 39 to 82). Hormone receptor was positive in 18 patients (58%). Previous treatment with anthracyclines was reported in seven patients and radiation therapy in fourteen patients. The total number of TRS doses ranged from 5 to 17 with the median of 15. Mild IR occurred in two patients and rash occurred in one patient at the first dose. However, no IR and adverse events were observed after reducing to 100 ml saline. The average LVEF measured every 3 months was between 62.3% and 64.8%. No significant decrease in LVEF was reported with the largest decrease of 8% in one patient at the 12th month on treatment. Conversely, brain natriuretic peptide levels tended to decrease as the number of received doses increased. None of the subgroup analysis (age groups, adjuvant vs. metastatic setting, previous anthracycline treatment, and previous radiotherapy) showed statistical significance. Conclusions: Intravenous infusion of TRS with 100 ml saline over 30 minutes in breast cancer patients is considered safe based on results from the study. The safe treatment with shorter infusion time has benefit for both healthcare professionals and patients. Clinical trial information: UMIN000006710.

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.

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.

<b><i>Background:</i></b> The addition of trastuzumab to standard chemotherapy has improved survival in patients with HER2-positive breast cancer in neoadjuvant, adjuvant, and metastatic settings. In higher tumor stages, the addition of pertuzumab is now a standard of care and associated with a favorable toxicity profile. We evaluated the safety and efficacy of the trastuzumab biosimilar SB3 in combination with pertuzumab in HER2-positive breast cancer patients. <b><i>Methods:</i></b> Seventy-eight patients with HER2-positive breast cancer treated at the Division of Oncology at the Medical University of Graz were included. Summary measures are reported as medians (25th to 75th percentile) for continuous variables and as absolute frequencies (%) for count data. <b><i>Results:</i></b> Thirty-five patients received a median of 4 (3–7) cycles of trastuzumab biosimilar SB3 plus pertuzumab. All patients had a normal baseline left ventricular ejection fraction (LVEF; &#x3e;50%) prior to the initiation of SB3 plus pertuzumab treatment with a median LVEF of 60% (60–65). Twenty-one patients had a median absolute LVEF decline of 1% (–5 to 0). Two patients (5.7%) had a LVEF reduction ≤50%, but none ≥10%. There were no unexpected adverse events. Twenty-two of 35 patients (63%) were treated with trastuzumab biosimilar SB3 and pertuzumab in the neoadjuvant setting and 11 patients (50%) achieved a pathological complete response. The safety and the efficacy in this setting was comparable to the trastuzumab plus pertuzumab combination in neoadjuvantly treated matched samples. <b><i>Conclusion:</i></b> In this series of HER2-positive breast cancer patients, the combination of SB3 plus pertuzumab was consistent with the known safety and efficacy profile of trastuzumab and pertuzumab combination.

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]

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.
