Brief Summary

Investigators propose to study the efficacy of Bevacizumab plus systemic chemotherapy prior to surgery in order to make a locally advanced tumor operable. Treatment is thus expected to induce a maximum tumor shrinkage within a short period (usually 3-6 months). In addition Bevacizumab (Avastin) is to be administered as early as possible during the disease stages. The primary aim of this study is to evaluate the preliminary antitumor activity in terms of pathological complete responses (pCR) of bevacizumab in combination with chemotherapy.

Detailed Description

The aim of administering systemic therapy prior to surgery is to make a locally advanced tumor operable or to allow conservative surgery in the case of a T2-T3 tumor. Therefore, treatment is expected to induce a maximum tumor shrinkage within a short period. In addition and based on the anti-angiogenic MoA, bevacizumab (Avastin) is to be administered as early as possible during the disease stages. Bevacizumab has already been tested in the neoadjuvant setting with encouraging results. In a first trial patients with inoperable locally advanced breast cancer received docetaxel with or without bevacizumab with five clinical Complete Responses and 24 Partial Responses. In a second trial there was also reported the results of the combination of bevacizumab with doxorubicin and docetaxel for the treatment of inflammatory breast cancer. Then, a set of studies of primary therapy exploring the activity of different regimens have confirmed the role of baseline pathological features of the tumor in predicting the responsiveness to primary therapy. A 22% pathological complete responses (pCR) rate has been achieved in a study combining bevacizumab together with Xeloda and Taxotere suggesting that bevacizumab addition to chemotherapy in the neoadjuvant treatment is feasible showing promising activity while no unexpected toxicities were reported.

Thus, a very high interest exists from our clinicians mostly within our cooperative groups which cover the largest national oncology centers to be involved and run such a study.

• ECOG performance-status ≤1
• No prior or current neoplasm except for curatively treated non melanoma skin cancer, in situ carcinoma of the cervix
• No distant disease/secondary carcinoma
• Normal cardiac function
• Results of the following assessments at the time of inclusion must be available:

1. bilateral Mammography (before enrolment)

2. histology

3. grading

4. hormone-receptor-status

5. HER2 status negative (is defined as FISH/CISH negative or IHC0 or IHC1+, or IHC2+ and FISH/CISH negative)

• Laboratory requirements (within 1 week before enrolment):
