Fulvestrant in Postmenopausal Patients With Metastatic Breast Cancer

Overview

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.

Full Title of Study: “A Retrospective Study of Fulvestrant in Postmenopausal Patients With Metastatic Breast Cancer in Greece (The ‘RESPONSE’ Study)”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: September 2011

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?

Interventions

  • Drug: Fulvestrant
    • 250mg on d1,15,29 or 250mg on d1 q28days

Arms, Groups and Cohorts

  • Fulvestrant

Clinical Trial Outcome Measures

Primary Measures

  • Time to Progression
    • Time Frame: 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 Measures

  • Objective Response Rate
    • Time Frame: > 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
    • Time Frame: >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
