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

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

To understand the effects induced by acute hypoxia that sets in during surgery in breast cancer. To study this, clinical samples (Tumor biopsies) will be obtained during the surgery after partial devascularisation (sample B) and stored for future genomic and proteonomic evaluations.

Three tumor samples will be obtained after the patient is under anaesthesia,

1. Prior to starting surgery (Sample A)
2. The middle intra-operative sample, which will be collected when half the tumour has been devascularized (i.e., somewhere midway during the surgery). (Sample B)
3. A third post excision (anoxic sample C). These tumour tissue samples will be stored as snap frozen, in RNA later and as paraffin sections.

To understand the effects induced by acute hypoxia that sets in during surgery in breast cancer. To study this, clinical samples (Tumor biopsies) will be obtained during and stored for future genomic and proteonomic evaluations.
