ClinConnect Summary

This clinical trial is studying a combination treatment for women with locally advanced HER2-positive breast cancer. Participants will receive a regimen of docetaxel, carboplatin, Inetetamab, and Pyrotinib before surgery, with the goal of achieving significant tumor reduction. Researchers will evaluate how effective this treatment is by looking at tumor and lymph node status after treatment, as well as monitoring long-term outcomes like survival rates and any potential side effects, particularly heart-related issues.

To be eligible for this trial, women aged 18 to 75 with a confirmed diagnosis of invasive breast cancer are invited to participate. Key requirements include having a tumor larger than 2 cm and being HER2-positive. Interested participants should not have received previous cancer treatments or have certain health conditions that could complicate the study. Throughout the trial, participants can expect regular check-ins and close monitoring, all while contributing to research that could help improve future breast cancer treatments.

• • 5. Severe cardiac disease or discomfort, including but not limited to the following: a history of heart failure or systolic dysfunction (LVEF \< 60%); high-risk uncontrolled arrhythmias, such as atrial tachycardia, resting heart rate \> 100 bpm , significant ventricular arrhythmia (eg, ventricular tachycardia) or higher-grade AV block (ie, Mobitz II second-degree AV block or third-degree AV block); antianginal medication indicated angina pectoris; clinically significant heart valve disease; transmural myocardial infarction on ECG; poorly controlled hypertension (systolic \> 180 mmHg and/or diastolic \> 100 mmHg);
