Brief summary
This study will investigate whether, in patients receiving breast cancer surgery, pre-operative Propranolol compared with placebo, changes the cancer's gene expression. Who is it for? You may be eligible to join this study if you are a female aged 18-70 years old, have histologically-confirmed breast cancer and will undergo breast cancer surgery at Peter MacCallum Cancer Centre. Study details Participants will be randomly allocated (by chance) to one of two treatment groups. Patients in one group will receive Propranolol for 7 days prior to their scheduled breast cancer surgery while patients in the other group will receive a placebo tablet over the same period. Tablets will be taken two times a day. To determine the results of the study, the researchers will compare blood tests and tumour samples (biopsy and excision samples) obtained before and after administration of the study medication (at the time of surgery). In the samples, the investigators will be looking for the behaviour of specific ‘anti-cancer’ immune cells in the blood and in the tissue surrounding and controlling the tumour. The investigators will also be analysing the immune cells to understand the biological effects of the ‘stress’ that a patient may be experiencing. The information from this study will be presented to clinicians and researchers and will provide very useful information to guide a larger study examining the role of propranolol in all patients receiving breast surgery or in those patients where breast cancer has spread.
