Evaluating the effects of hypoxia during breast cancer surgery

A Prospective Evaluation of the Peri-operative Hypoxia in Breast Cancer

Tata Memorial Hospital · NCT03797482

This study is testing how low oxygen levels during breast cancer surgery affect the tumor and treatment results by collecting samples at different stages of the procedure.

What this trial studies

This study aims to investigate the impact of acute hypoxia that occurs during surgery on breast cancer patients. It involves collecting three tumor samples at different stages of the surgical procedure: before surgery, midway through when the tumor is partially devascularized, and after excision. These samples will be preserved for future genomic and proteomic analysis to better understand the biological effects of hypoxia on tumor behavior and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are female patients diagnosed with breast cancer who are scheduled for surgery and have not received prior chemotherapy or surgical intervention.

Not a fit: Patients with metastatic breast cancer or those who have undergone any anticancer therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved surgical strategies and treatment protocols for breast cancer patients.

How similar studies have performed: While the specific approach of evaluating intra-operative hypoxia in breast cancer is relatively novel, similar studies in other cancer types have shown promising results.
