Impact of Propranolol Strategies on Myocardial Injury After Breast Cancer Surgery (B-BIT)

12 mei 2026 bijgewerkt door: Chang-Ik Yoon

A Pragmatic Clinical Trial to Evaluate the Impact of Clinical Propranolol Strategies on Myocardial Injury After Non-cardiac Surgery (MINS) in Patients Undergoing Breast Cancer Surgery With Hypertension or Angina

This study aims to evaluate the impact of using propranolol, a non-selective beta-blocker, on preventing myocardial injury after non-cardiac surgery (MINS) in breast cancer patients who also have hypertension or angina. Stress from surgery and anesthesia can increase sympathetic activity and inflammation, which may lead to heart stress. This pragmatic clinical trial will compare patients who are prescribed propranolol as part of their routine care with those who are not. Researchers will analyze blood samples and surgical tissues collected during normal treatment to observe changes in heart health and the tumor microenvironment.

Studie Overzicht

Gedetailleerde beschrijving

Breast cancer is the most common malignancy among women in Korea. Perioperative stress and acute physiological stimuli from surgery and anesthesia increase catecholamine secretion, which can lead to Myocardial Injury after Non-cardiac Surgery (MINS). Propranolol is known to stabilize hemodynamic variability by inhibiting sympathetic surge and reducing myocardial oxygen consumption. Recent studies also suggest that beta-blockers may influence the tumor microenvironment (TME) by reducing inflammation and regulating immune cell composition.This prospective, randomized, open-label, single-center pragmatic clinical trial will enroll 100 female patients (aged 20-70) with stage I-III breast cancer and comorbid hypertension or angina. Participants will be randomized 1:1 into two groups:

  1. Propranolol Group: Patients receive propranolol for at least 14 days before surgery.
  2. Non-Propranolol Group: Patients receive usual care without propranolol.The primary objective is to compare the incidence of MINS based on high-sensitivity Troponin T (hs-TnT) levels measured postoperatively. Exploratory objectives include analyzing markers of inflammation (CRP, LDH), tumor proliferation (Ki-67), and tumor-infiltrating lymphocytes (TILs) using blood and tissue samples naturally obtained during the clinical process. Long-term follow-up will be conducted for up to 5 years to evaluate recurrence and survival outcomes.
