NCT06660628

Brief Summary

The study is a single-center, prospective, non-randomized controlled study. The primary objective is to examine the clinical outcomes of utilizing Deep Inspiration Breath Hold (DIBH) in conjunction with hypo-fractionated radiotherapy for patients diagnosed with left-sided breast cancer with a particular focus on its potential to reduce the incidence of cardiac-related clinical and subclinical events.Participants will revieve large segmentation sadiotherapy ± DIBH for left breast cancer and be followed up to gather their clinical cardiac imformation.

Outcome Measures

Primary Outcomes (1)

  • Incidence of subclinical and clinical cardiac events

    1. Clinical events: newly emerged cardiac diseases after radiotherapy include acute and delayed pericarditis, pericardial effusion and constrictive pericarditis, coronary artery disease, myocardial infarction, cardiac valve disease and arrhythmia. 2. Subclinical events: new electrocardiogram (ECG) abnormalities, echocardiographic abnormalities, and abnormal elevations of cardiac enzymes after radiotherapy.

Eligibility Criteria

Age18 Years - 70 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years old, female, life expectancy \> 5 years
  • ECOG 0, 1, 2 points
  • Pathologically diagnosed with left breast cancer and underwent breast-conserving surgery or modified radical mastectomy
  • The patient will receive radiation therapy to the entire breast or chest wall ± the lymphatic drainage area above and below the clavicle ± the lymphatic drainage area in the axilla.
  • No prior neoadjuvant chemotherapy or breast reconstruction.
  • No active cardiac disease, myocardial infarction, or congestive cardiac failure at baseline.
  • Patients can hold their breath for at least 30 seconds after training
  • Patients who can be followed up and agree to follow the plan.
  • Sign the consent form.

You may not qualify if:

  • Lesions were observed on both sides of the breast.
  • Diagnosis could not be confirmed by pathology.
  • Distant metastasis was identified.
  • The patient had undergone neoadjuvant chemotherapy or breast reconstruction surgery.
  • Severe cardiac insufficiency; myocardial infarction or uncorrected unstable cardiac arrhythmia or uncorrected unstable angina within the last 3 months; or pericardial disorders
  • The patient's New York Heart Association (NYHA) cardiac classification is within categories 2-4.
  • A history of chronic lung disease, including conditions that may contribute to ductal dilatation, such as chronic obstructive pulmonary disease (COPD) and interstitial pneumonia.
  • Previous mediastinal radiotherapy.
  • Previous or concurrent second primary malignant tumor (except skin cancer that is not a malignant black pigmented tumor, papillary/follicular carcinoma of the thyroid, carcinoma in situ of the cervix, and contralateral non-invasive breast cancer).
  • Irradiation of the lymphatic drainage area of the internal breast is required.
