Design outcomes

| Measure | Time frame |
|---|---|
| Primary end point(s): the primary outcome measure for this study is an increase in apoptotic index between diagnostic core biopsy and repeat core biopsy taken on day 5 of study ;Main Objective: the principle objective is to study the short-term biological effects of treatment and whether the addition of zoledronic acid to combination neoadjuvant (pre-operative) chemotherapy causes additive or synergistic efects on tumour growth ininvasive breast cancer; specifically assessing apoptosis (programmed cancer cell death) and proliferation (cancer activity). It is hoped the study will determine whether the addition of zoledronic acid to neoadjuvant chemotherapy causes an increase in apoptosis between the diagnostic core biopsy and an additional core biopsy for research purposes on day 5, compared to neoadjuvant chemotherapy alone ; Secondary Objective: the secondary objectives of the study are: 1) to determine whether the addition of zoledronic acid to neoadjuvant chenotherapy casuers a reduction in proliferation between the preoperative core biopsy, the day 5 interim biopsy and the operative tumour sample, compared to neoadjuvant chemotheraoy alone. 2) to determine the pattern of expression of serum angiogenesis biomarkers (markers of new tumour blood vessel formation in the bloodstream) at randomisation, day 5, before the second cycle of chemotherapy and prior to surgery 3) to measure bone markers at randomisation, day 5, before the second cycke of chemotherapy and prior to surgery (to assess if bone turnover and activity has reduced 4) to detect the presence of circulating tumour cells in the peripheral blood (taken at randomisation, day 5, before the second cycle of chemotherapy and prior to surgery) and any changes in response to treatment | — |
