Project Description

*FUNDING CONFIRMED*

The aim of this study is to estimate the effect of drug-exposures at surgery on breast cancer recurrence using statistical methodologies for maximising causal inference in observational datasets.

For an important minority of breast cancer patients their breast cancer recurs. An understanding of modifiable perioperative drug exposures is necessary to inform clinical practice and minimise local or distant disease recurrence.

The proposed study will use data available within the Northern Ireland (NI) Cancer Registry from 1,802 patients diagnosed in NI from 2009-2010 with early stage breast cancer (stage I-IIIa) who have undergone surgery.

Drawing on the literature and clinical experience, acyclic causal diagrams will be employed to identify variables involved (including confounders) in the causal pathway between perioperative drug exposures and breast cancer recurrence, such as non-steroidal anti-inflammatory drugs, analgesic opioids, dexamethasone, and anaesthesia (regional vs general). The information on these variables will be obtained by review of the patients’ theatre and anaesthetic records.

Inverse probability-weighted analysis will estimate the parameters of a marginal structural model, and represent the causal effect of perioperative drug exposure on recurrence. The results will inform clinical practice in the perioperative period.
