Breast Cancer Clinical Trial
Side Effects Involving the Heart in Women With Breast Cancer Receiving Doxorubicin and Trastuzumab
RATIONALE: Studying samples of blood and tissue in the laboratory from women receiving doxorubicin and trastuzumab for breast cancer may help doctors learn more about changes that occur in DNA and identify biomarkers for increased risk of cardiac effects.
PURPOSE: This clinical trial is studying side effects involving the heart in women with breast cancer receiving doxorubicin and trastuzumab.
To determine if polymorphisms in genes (e.g., CYBA, RAC2, NCF4, MRP1, MRP2, GTSP and CBR3) in women with breast cancer treated with doxorubicin hydrochloride increase the relative risk of developing ≥ NCI grade 1 cardiotoxicity. (Primary study)
To determine whether pre-treatment levels of biomarkers (e.g., neuregulin, IGF-1, cardiotrophin-1, IL-6, VEGF, hepatocyte growth factor, and heparin binding EGF) in these patients, correlate with relative risk of developing ≥ NCI grade 1 cardiotoxicity to this regimen. (Primary study)
To determine whether decreased heart rate variability and increased plasma levels of norepinephrine at 3 weeks after completion of this regimen correlate with relative risk of developing ≥ NCI grade 1 cardiotoxicity in these patients. (Primary study)
To determine whether decrease in endothelial progenitor cell (EPC) number at 3 weeks after completion of this regimen can be detected, and if so whether decreased EPC number correlates with ≥ NCI grade 1 cardiotoxicity. (Primary study)
To determine whether baseline physical fitness level of these patients, assessed by a questionnaire and 6 minute walk distance, correlates with relative risk of developing ≥ NCI grade 1 cardiotoxicity to this regimen. (Primary study)
To determine whether activity level of these patients during treatment, assessed by questionnaire, correlates with relative risk of developing ≥ NCI grade 1 cardiotoxicity to this regimen. (Primary study)
To determine whether drop in functional capacity of these patients, measured by 6 minute walk distance at the end of treatment with this regimen, correlates with ≥ NCI grade 1 cardiotoxicity. (Primary study)
To determine whether MRI can detect changes in diastolic heart function in these patients 48 hours after administration of this regimen. (Sub-study A)
To determine if a greater decrease in diastolic dysfunction in these patients at 48 hours is predictive of greater decrease in systolic function at 3 weeks after treatment with this regimen. (Sub-study A)
To determine whether levels of certain biomarkers of cardiac myocyte damage, B-type natriuretic peptide and the sarcomere protein troponin T at 48 hours after the initial exposure to these drugs correlate with relative risk of developing ≥ NCI grade1 cardiotoxicity. (Sub-study A)
To determine whether trastuzumab given concurrently with doxorubicin hydrochloride decreases heart rate variability and increases plasma levels of norepinephrine in these patients, and if so, whether these changes correlate with relative risk of developing NCI grade ≥ 1 cardiotoxicity. (Sub-study B)
To determine whether EPC number obtained from patients treated with trastuzumab have decreased migration into microvascular structures in an ex vivo assay and whether these changes correlate with ≥ NCI grade 1 cardiotoxicity. (Sub-study B)
To determine whether levels of certain biomarkers in these patients , including neuregulin, IGF-1, cardiotrophin-1, IL-6, VEGF, hepatocyte growth factor and heparin binding EGF, change after exposure to trastuzumab. (Sub-study B)
OUTLINE: This is a multicenter study.
Primary study: Patients make an initial visit (before beginning doxorubicin hydrochloride treatment) and a visit 3 weeks after the 4th course of doxorubicin hydrochloride (approximately 12 weeks after the initial visit). During these visits, blood samples are also collected for measuring serum levels of neuregulin-1, IGF-1, cardiotropin-1, IL-6, VEGF, hepatocyte growth factor, and plasma norepinephrine and endothelial progenitor cells (EPC). Heart-rate variability (HRV) is measured and, if necessary, a transthoracic echocardiogram is performed. Patients complete baseline health and activity level questionnaire and suitable patients complete a 6-minute walk test. Patients undergo blood collection for genotype analysis for single nucleotide polymorphism sites during the initial visit.
Patients complete a questionnaire assessing physical activity at the beginning of the 2nd, 3rd, and 4th courses of chemotherapy.
Sub-study A (MRI)*: In addition to the assessments performed in the primary study, patients undergo some extra tests. During initial visit, patients have an additional blood sample collected during initial visit for measurement of B-type natriuretic peptide (BNP) and troponin T and undergo cardiac MRI. Approximately 48 hours after the first dose of doxorubicin hydrochloride, patients undergo an additional visit, during which blood samples are collected for BNP and troponin T and an cardiac MRI is performed.
NOTE: *Patients who enroll in sub-study A must also be enrolled in the primary study.
Sub-study B (trastuzumab)*: In addition to the assessments performed in the primary study, patients undergo some extra tests. Patients undergo an additional visit after the third treatment of trastuzumab (approximately 6 months after the first dose of doxorubicin hydrochloride), during which patients have blood samples collected and analyzed as in Primary study visit 2. HRV is measured and, if necessary, a transthoracic echocardiogram is performed.
NOTE: *Patients who enroll in sub-study B must also be enrolled in the primary study.
After completion of study treatment, patients are followed periodically for up to 5 years .
