Brief summary

The goal of the study is to explore the efficacy and safety of hyperbaric oxygen therapy in the neoadjuvant treatment of triple-negative and HER2+ breast cancer patients

Interventions

Patients who meet the inclusion criteria will be enrolled and given hyperbaric oxygen intervention, with a minimum of 5 hyperbaric oxygen treatments per chemotherapy cycle, one per day for 60-90 minutes, for a total of 30-40 hyperbaric oxygen treatments (100% oxygen at a pressure of 2.0 ATA).

Premature and/or low body mass neonates. Lung disease (severe chronic obstructive pulmonary disease). Diseases of the lungs (severe chronic obstructive airway disease, herpetic lung disease, acute or chronic lung infections, uncontrolled asthma, uncontrolled diarrhoea). controlled asthma, untreated pneumothorax), history of previous middle ear surgery, middle ear disease (eustachian tube Dysfunction of the eustachian tube, recurrent episodes of vertigo), ocular disease (retinal detachment). 2. previous hyperbaric oxygen therapy. 3. distant metastases, including lymph node metastases to the contralateral breast and mediastinum. 4. other malignant tumours within the last two years, except for radically treated basal or squamous cell carcinoma of the skin or CIS of the cervix.

Design outcomes

Primary

MeasureTime frame
pCR rate after hyperbaric oxygen combined with neoadjuvant therapy in breast cancer patientsAfter completion of standard cycle of neoadjuvant therapy (through study completion, an average of half a year)

Secondary

MeasureTime frameDescription
RCB 0/1 rateAfter completion of standard cycle of neoadjuvant therapy (through study completion, an average of half a year)RCB (Residual Cancer Burden) is a commonly used metric to assess the extent of residual tumor burden after neoadjuvant therapy, such as chemotherapy, radiation therapy, or targeted therapy. RCB 0: Complete response (CR) - No visible residual tumor, complete disappearance of the tumor. RCB I: Minimal residual disease - Only a small amount of residual tumor remains, with limited tumor volume and few lymph node metastases. RCB II: Moderate residual disease - Moderate degree of tumor residual is present. RCB III: Extensive residual disease - A large amount of residual tumor remains, often with more lymph node metastases.
RECIST criteriaAfter completion of the first cycle of neoadjuvant therapy (at about 1 month), After completion of standard cycle of neoadjuvant therapy (through study completion, an average of half a year)
