You may be eligible if
All patients:
Aged ≥ 18 years
Female
MSK histologically confirmed primary invasive breast carcinoma
Pathologically confirmed HER2-positive breast cancer
Treated with adjuvant trastuzumab (either alone or in combination with other anti-HER2 agents)
≥ 2 years since completion of targeted chemotherapy without evidence of disease
Willing and able to comply with the requirements of the protocol
Patients in the cardiotoxicity (TOX) group must meet the following criteria:
Development of treatment associated cardiotoxicity during trastuzumab therapy, defined as an absolute decrease from baseline in LVEF by ≥ 10%, to an LVEF of below 55%.
No clinical signs or symptoms of heart failure (NYHA class III or IV) at the time of cardiotoxicity.
Note: NYHA Class III symptoms include marked limitation of physical activity. Less than ordinary activity causes fatigue, palpitation, dyspnea, or anginal pain. NYHA Class IV symptoms include inability to carry on any physical activity without discomfort. Symptoms of heart failure or anginal syndrome may be present at rest, and if any physical activity is undertaken, discomfort is increased.
Patients in the no cardiotoxicity (NO-TOX) group must meet the following criteria:
Maximum absolute decrease in LVEF ≤ 5% from baseline during trastuzumab therapy.
Echocardiogram with LVEF assessment performed at baseline (prior to initiation of trastuzumab therapy) and at least two timepoints during trastuzumab therapy.
LVEF ≥ 55% on each echocardiogram assessment during trastuzumab therapy.
No clinical signs or symptoms of heart failure (NYHA class III or IV) during trastuzumab treatment.
Note: NYHA Class III symptoms include marked limitation of physical activity. Less than ordinary activity causes fatigue, palpitation, dyspnea, or anginal pain. NYHA Class IV symptoms include inability to carry on any physical activity without discomfort. Symptoms of heart failure or anginal syndrome may be present at rest, and if any physical activity is undertaken, discomfort is increased.
Participants in the healthy control group must meet the following criteria:
Aged ≥ 40 years
Female
No history of cancer with the exception of localized basal and/or squamous cell carcinoma of the skin
No prior history of known cardiac disease (e.g. ischemic heart disease, heart failure, cardiomyopathy, or valvular heart disease \[moderate to severe\], or significant arrhythmias).
Willing and able to comply with the requirements of the protocol
You may not be if
Inability to provide informed consent
Presence of metastatic disease
Treatment with additional cardiotoxic therapy for a secondary malignant neoplasm, or treatment with additional cardiotoxic therapy for breast cancer recurrence since primary breast cancer diagnosis \[Note: Patients who are diagnosed with a second primary malignancy are not excluded from participation in the study, unless they meet this exclusion criterion.\]
Subjects must not have any of the following absolute contraindications to cardiopulmonary exercise testing : (a) acute myocardial infarction (within 3-5 days of any planned study procedures), (b) unstable angina, (c) uncontrolled arrhythmias causing symptoms or hemodynamic compromise, (d) symptomatic severe aortic stenosis, (e) recurrent syncope, (f) active endocarditis, (g) acute myocarditis or pericarditis, (h) uncontrolled heart failure, (i) acute pulmonary embolus or pulmonary infarction, (within 3 months of any planned study procedures), (j) thrombosis of lower extremities, (k) suspected dissecting aneurysm, (l) uncontrolled asthma, (m) pulmonary edema (within 3 months of planned study procedures), (n) room air desaturation at rest ≤85%, (o) respiratory failure, (p) acute noncardiopulmonary disorder that may affect exercise performance or be aggravated by exercise (i.e., infection, renal failure, thyrotoxicosis), or (q) mental impairment leading to inability to cooperate.
