Brief summary

This is an observational study for patients with breast cancer that will be treated with doxorubicin (Adriamycin) and/or trastuzumab (Herceptin). The study will help the investigators learn more about how these medications affect the heart and how those effects relate to patients' medical history and social determinants of health (such as race, gender identity, education, occupation, access to health services and economic resources). Patients on this study will have echocardiograms, blood draws, and answer questions about their symptoms and activity level. Patients will be followed on this study for up to 15 years.

Detailed description

The investigators propose a prospective longitudinal cohort of breast cancer patients treated with anthracyclines and/or trastuzumab to determine the associations between social determinants of health (SDOH) and cardiotoxicity risk and to determine whether associations between SDOH and cardiotoxicity risk differ according to race. Patients will be followed with serial echo, blood draw, and surveys every 3 months for the first year, then annually for two years. After 3 years following start of cancer therapy, patients will have study visits every other year for up to 15 years.

Interventions

OTHERSocial Determinants of Health

The study will perform detailed phenotyping of Social Determinants of Health using the National Institute of Minority Health and Health Disparities PhenX SDOH toolkit at baseline.

Design outcomes

Primary

MeasureTime frameDescription
Change in Left Ventricular Ejection Fraction (LVEF)through study completion (expected to be 15 years)Absolute change in LVEF by echocardiogram at follow-up

Secondary

MeasureTime frameDescription
Change in Longitudinal Strainthrough study completion (expected to be 15 years)Change in longitudinal strain by echo from baseline
Change in Circumferential Strainthrough study completion (expected to be 15 years)Change in circumferential strain by echo from baseline
Cancer therapy-related cardiac dysfunction (CTRCD)through study completion (expected to be 15 years)Incidence of CTRCD defined as at least a 10% absolute change in LVEF by echocardiogram at follow-up relative to baseline to a value \< 50%
Change in Diastolic functionthrough study completion (expected to be 15 years)Change in diastolic function defined as E/e' by echo from baseline
Change in Left Ventricular (LV) Massthrough study completion (expected to be 15 years)Change in LV Mass by echo from baseline
Change in Relative LV Wall Thicknessthrough study completion (expected to be 15 years)Change in relative LV wall thickness from baseline
Change in Ventricular-Arterial Couplingthrough study completion (expected to be 15 years)Change in Ventricular-Arterial Coupling defined as Ea/Ees by echo from baseline
Symptomatic Heart Failure (HF)through study completion (expected to be 15 years)Incidence of symptomatic heart failure (centrally adjudicated)
Change in LV Torsionthrough study completion (expected to be 15 years)Change in LV Torsion measured by 3D echo from baseline
Change in NTproBNPthrough study completion (expected to be 15 years)Change in NTproBNP measured in batches from banked samples from baseline.
Change in high-sensitivity troponin (hsTnT)through study completion (expected to be 15 years)Change in hs-TnT measured in batches from banked samples from baseline.
Change in patient reported fatiguethrough study completion (expected to be 15 years)Change in Patient Reported Outcomes Information System (PROMIS) Fatigue Score from baseline. A higher score corresponds to higher reported levels of fatigue.
Change in patient reported quality of lifethrough study completion (expected to be 15 years)Change in Patient Reported Outcomes Information System (PROMIS) Global Health score from baseline. Higher scores indicate a healthier patient.
Change in patient reported activity levelthrough study completion (expected to be 15 years)Change in total weekly leisure activity in METS assessed by Godin Leisure Time Exercise Questionnaire from baseline.
Change in LV Twistthrough study completion (expected to be 15 years)Change in LV Twist measured by 3D echo from baseline
