About this study
This study focuses on preoperative treatment modalities for luminal-type locally advanced breast cancer. Based on modern precision radiotherapy technologies such as MRI-Linac, CyberKnife, and VMAT, it aims to compare the pCR rate, breast conserving surgery (BCS) rate, progression-free survival (PFS), and treatment-related side effects between preoperative neoadjuvant chemotherapy and preoperative neoadjuvant SBRT combined with chemotherapy in patients with this type of breast cancer. The goal is to provide new strategic options for the preoperative treatment of luminal-type locally advanced breast cancer.
Read the detailed description
Breast cancer is a tumor with high tumor heterogeneity, and treatment outcomes vary significantly across different molecular subtypes. In recent years, the emergence of novel treatment methods has significantly improved the overall survival and progression-free survival of patients with early-stage, especially metastatic tumors. However, a portion of patients with locally advanced breast cancer (LABC) still have poor prognoses. As early as the 1970s, preoperative radiotherapy was applied to locally advanced breast cancer to increase resectability, but due to limitations in radiotherapy techniques and other factors, preoperative radiotherapy increased the incidence of acute toxic reactions and postoperative complications. Compared to traditional postoperative radiotherapy, neoadjuvant radiotherapy has several theoretical advantages, such as more precise tumor target localization, optimization of breast reconstruction radiotherapy strategies, increased tumor downstaging to improve breast-conserving surgery opportunities, and improved pathological complete response rates, potentially eliminating the need for breast surgery. With the advent of the era of precision radiotherapy, modern radiotherapy technologies have provided solutions to reduce the acute toxic reactions associated with preoperative radiotherapy. This study focuses on preoperative treatment modalities for luminal-type locally advanced breast cancer. It aims to compare the pCR rate, breast-conserving surgery (BCS) rate, progression-free survival (PFS), and treatment-related side effects between preoperative neoadjuvant chemotherapy and preoperative neoadjuvant SBRT combined with chemotherapy in these patients. The goal is to provide new strategic options for the preoperative treatment of luminal-type locally advanced breast cancer.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study focuses on preoperative treatment modalities for luminal-type locally advanced breast cancer. Based on modern precision radiotherapy technologies such as MRI-Linac, CyberKnife, and VMAT, it aims to compare the pCR rate, breast conserving surgery (BCS) rate, progression-free survival (PFS), and treatment-related side effects between preoperative neoadjuvant chemotherapy and preoperative neoadjuvant SBRT combined with chemotherapy in patients with this type of breast cancer. The goal is to provide new strategic options for the preoperative treatment of luminal-type locally advanced breast cancer.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Qian Peng, Phd (86-028-85420059, pengqian@scszlyy.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pCR (time frame: From enrollment to one month after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06697938, which also lists 22 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2024.
