The GAEA Initiative:

Survey Rationale and Methodology

 

Background Information

 

 

Women who have had surgical treatment for early breast cancer are at risk of local or distant recurrence and of developing a tumour in the other breast.  The risk for an individual woman is not well defined and it is difficult for doctors to provide definitive advice about this risk. Adjuvant endocrine therapy is used in the treatment of women with hormone responsive breast cancer to reduce the risk of recurrence.  The treatment traditionally lasts five years, although this can be extended for an additional five years to further reduce the risk of recurrence.  Little is currently known about womenÕs experience of and knowledge about adjuvant endocrine therapy.  Filling this gap in medical knowledge was the key driver behind The GAEA Initiative. 

 

The GAEA Initiative involves a large European survey of post-menopausal women undergoing adjuvant endocrine therapy for early breast cancer.  The survey set out to determine post-menopausal patientsÕ knowledge about the risk of recurrence in early breast cancer, define their understanding of the purpose of adjuvant endocrine treatment, their attitudes towards it and to identify their informational and support needs, and how these can be met.

 

Who participated in the GAEA survey?

The survey was conducted among post-menopausal women in nine European countries (Austria, France, Germany, Hungary, Italy, Spain, Sweden, Switzerland and the United Kingdom).  A total of 547 questionnaires were analysed.

Women were eligible to complete the survey if they had been diagnosed with early breast cancer (defined as localised to the breast tissue and/or nearby lymph nodes), were post-menopausal, currently receiving adjuvant endocrine therapy that commenced at least one year ago and lived in one of the nine survey countries listed above.

 

How was the survey conducted?

The GAEA research was divided into two stages:  qualitative and quantitative.  In both cases, the research was carried out by independent research agency Adelphi International Research.

 

STAGE I: QUALITATIVE

The qualitative stage of the research, carried out in a small group of patients in January and February 2006, aimed to identify the correct issues of importance to patients from different regions and to determine the appropriate level of language to be used in the questionnaire.  Insights from this stage of the research formed the basis of the development of the quantitative second stage of the research.

 

A purposive sample of 32 women with early breast cancer took part in either one-to-one interviews or a focus group (in Sweden).  Interviews were recorded, transcribed and analysed in the local language.

 

This initial research gathered information on: attitudinal aspects of adjuvant endocrine therapy;  patientsÕ understanding of the purpose of adjuvant endocrine treatment and the risk of recurrence; attitudes towards adjuvant endocrine treatment; information and support and involvement in the decision making process relating to the selection of endocrine treatment.

 

STAGE II: QUANTITATIVE

Stage II of the research was carried out from May to July 2006 and the data analysis was completed in August 2006.  A much larger sample of patients was recruited into the second stage of research, with the aim of gathering detailed insight into breast cancer patientsÕ knowledge about and attitudes towards adjuvant endocrine therapy and their level of awareness of the risk of recurrence.

 

Recruitment

The GAEA survey was publicised via the GAEA collaborating organisations, other European patient advocacy groups as well as through advertisements in the press and the Internet. To assist in patient recruitment, an informational flyer was prepared and a free phone number was provided for patients to call for additional information on GAEA prior to committing to the survey. Posters were also displayed in pharmacies and clinics to aid recruitment.

 

Methodology

Several methods of completing the GAEA questionnaire were available to women who wished to participate in the survey: self-completion and returning questionnaire by post using a pre-paid envelope; self-completion by Internet (UK language and Austria only); interviewer assistance by telephone using a free phone number; or interviewer assistance in person.

 

Written information was provided to all patients, including a summary of the survey objectives, a brief description of the process and expectations of the patient, and a free phone number for further information.

 

The questionnaire was divided into three sections:

 

In order to encourage honest and open responses from patients the survey was analysed anonymously, and personal details of participants were not be shared with any third party. 

 

How will the survey results be communicated?

The topline survey results are presented at the 31st congress of the European Society for Medical Oncology (ESMO), 29 September to 3 October 2006, Istanbul, Turkey.  In addition, the GAEA data will be published in a GAEA Survey Report and will be submitted as manuscripts to peer review papers.
