Brief summary
This is a retrospective chart-review study that will be based on the collection of data from electronical or paper-based medical records with available data on patients who have commenced treatment with fulvestrant after January 1st of 2007. All necessary information for the purposes of the present study will be collected with the use of a paper-Case Record Form.
Detailed description
To date, there are no available data on the use of fulvestrant in the treatment of postmenopausal women with metastatic breast cancer in current clinical practice in Greece. In view of this significant lack of knowledge, we designed this retrospective study in order to evaluate the effectiveness of fulvestrant in real-life settings, by obtaining data regarding the use of fulvestrant in current clinical practice among treating physicians in Greece. This retrospective study aims to address the following questions: * What is the clinical outcome of fulvestrant treatment in terms of TTP when used in metastatic breast cancer in a real life clinical setting? * What is the positioning of fulvestrant in the hormone therapy sequencing in metastatic breast cancer in Greece? * What are the other clinical outcomes (ORR, duration of response, CBR) of fulvestrant treatment in metastatic breast cancer in a real life clinical setting and what is the relation between clinical outcomes and fulvestrant's position in the treatment sequence? * What is the usual duration of fulvestrant treatment in metastatic breast cancer in the real life clinical setting and which are the reasons for treatment discontinuation? * Treatment failure with fulvestrant: what is the next step in sequencing according to patients' breast cancer treatment history?

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to Progression | 1 year | To evaluate the time to progression (TTP) from the initiation of fulvestrant treatment in postmenopausal women with endocrine-positive breast cancer who have failed at least one prior endocrine therapy, either as adjuvant treatment or for the treatment of advanced disease |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate | > 6 months | To evaluate the objective response rate (ORR), i.e. the rate of both complete and partial response, and to estimate the duration of response while on treatment with fulvestrant |
| Tumor growth control | >6 months | To evaluate the clinical benefit rate (CBR), i.e. the rate of both complete and partial response as well as stable disease ≥ 6 months, while on treatment with fulvestrant, where applicable |
