Brief Summary
The goal of this observational study is to evaluate cardiac side effects in women with early-stage breast cancer who receive systemic chemotherapy and/or anti-HER2 therapy as part of their standard cancer care. The main questions it aims to answer are: Can changes in Global Longitudinal Strain (GLS) on echocardiography detect early cardiac dysfunction before a drop in left ventricular ejection fraction (LVEF) becomes apparent? Are changes in circulating microRNA levels in the blood associated with early cardiac dysfunction during cancer treatment? Does cardiac dysfunction occur more frequently with anthracycline-containing chemotherapy compared to anthracycline-free regimens? Participants already receiving standard chemotherapy and/or anti-HER2 therapy as part of their routine cancer care will undergo echocardiography (LVEF and GLS), provide blood samples for microRNA analysis, and complete quality of life questionnaires at four time points: before treatment (baseline), and at 3, 6, and 12 months after starting treatment.

Outcome Measures
Primary Outcomes (1)
Incidence of cancer therapy-related cardiac dysfunction (CTRCD)
CTRCD defined per ESC 2022 Cardio-Oncology Guidelines as: an absolute LVEF reduction of ≥10 percentage points to a value below 53%, AND/OR a relative reduction in GLS of ≥15% from baseline. LVEF is measured by transthoracic echocardiography using Simpson's biplane method; GLS is measured by speckle-tracking analysis using a standardized protocol.
From baseline through Month 12
Secondary Outcomes (11)
Change from baseline in Left Ventricular Ejection Fraction (LVEF)
Baseline, Month 3, Month 6, Month 12
Change from baseline in Global Longitudinal Strain (GLS)
Baseline, Month 3, Month 6, Month 12
Change in circulating microRNA expression and association with cardiac function
Baseline, Month 3, Month 6, Month 12
Comparison of CTRCD incidence between anthracycline-containing and anthracycline-free regimens
From baseline through Month 12
Change from baseline in health-related quality of life: EORTC QLQ-C30
Baseline, Month 3, Month 6, Month 12
- +6 more secondary outcomes
Study Arms (1)
Early-stage breast cancer patients receiving systemic therapy
Adult women with histologically confirmed Stage I-III breast cancer for whom neoadjuvant or adjuvant chemotherapy and/or HER2-targeted systemic therapy is planned, with baseline left ventricular ejection fraction ≥ 50%. Patients receive standard-of-care systemic therapy as determined by their treating oncologist; the study does not modify treatment selection, dose, or duration. For analytic purposes, patients are sub-grouped by chemotherapy regimen (anthracycline-containing vs. anthracycline-free) for comparative analyses of cardiac function and circulating microRNA changes.
Eligibility Criteria
Adult women with histologically confirmed Stage I-III breast cancer for whom neoadjuvant or adjuvant systemic therapy (chemotherapy and/or HER2-targeted therapy) is planned, recruited from the Medical Oncology outpatient clinic at Gazi University Faculty of Medicine Hospital, Ankara, Türkiye.
You may qualify if:
- Histologically confirmed diagnosis of breast cancer
- Stage I, II, or III disease
- Planned neoadjuvant or adjuvant chemotherapy and/or HER2-targeted systemic therapy
- Baseline transthoracic echocardiographic left ventricular ejection fraction (LVEF) ≥ 50%
- Age ≥ 18 years
- Able and willing to provide written informed consent
You may not qualify if:
- Metastatic (Stage IV) breast cancer
- Pre-existing heart failure or clinically significant cardiac disease
- Prior exposure to chemotherapy or other cardiotoxic systemic therapy
- Concurrent active malignancy other than breast cancer
- Inability or unwillingness to comply with the planned follow-up and assessment schedule

Biospecimen
Peripheral venous whole blood samples are collected in EDTA tubes at four time points (baseline, Month 3, Month 6, and Month 12). Total nucleic acid is isolated from whole blood for downstream quantitative analysis of circulating microRNAs (miR-34a, miR-146a, miR-21, miR-155, miR-1, miR-133a, miR-208a, and miR-499) by reverse transcription quantitative real-time PCR. Samples are stored at -80°C at the Department of Medical Biology, Gazi University Faculty of Medicine, until analysis. Samples are used solely for the purposes of this study and will be destroyed upon study completion in accordance with applicable regulations.
