Observational survey aiming to evaluate the tolerability of Aromasin and the ways in which it is used in clinical practice in France (as adjuvant endocrine therapy).

It was hypothesized that 200 participating doctors would provide the survey with sufficient statistical precision to meet the objectives, with each participating doctor recruiting up to 6 patients. An initial sample of 1000 doctors should be contacted (letter, phone).

These 1000 doctors will initially be chosen at random from a file held by Pfizer of doctors who have agreed to take part in a Pfizer survey.

These doctors will be experienced and qualified in the treatment and management of patients with non-metastatic, surgically-treated breast cancer (medical oncologists, gynaecologists, and medical oncologists/ radiation oncologists). They are practicing in general hospitals, teaching hospitals, CRLCC cancer centres and private clinics treating patients with breast cancer.

Study recruitment was stopped due to difficulty in enrolling the targeted number of patients on December 3, 2010. There were no safety concerns involved in the decision to stop enrollment.

Inclusion Criteria:

Postmenopausal patients, defined as: natural menopause for at least 1 year, surgical ovariectomy, chemotherapy-induced amenorrhoea for at least 2 years.

Patients who have had surgical treatment for histologically confirmed breast cancer that was nonmetastatic at the time of the initial diagnosis.

Patients whose tumour was hormone receptor positive (HR+, ER+ and/or PR+). Patients initiated on Aromasin at least 2 months before inclusion but not more than 1 year.

Exclusion Criteria:

Patients for whom Aromasin treatment is contraindicated. Presence of metastasis or a contralateral tumour. Another adjuvant endocrine therapy. Another concomitant antineoplastic treatment (except for Herceptin®). Participation in a clinical trial with an investigational drug during the 30 days prior to enrolment in the study.

Postmenopausal patients, hormone receptor positive, who have had surgical treatment for histologically confirmed early breast cancer that was nonmetastatic at the time of the initial diagnosis, treated by Aromasin as adjuvant endocrine therapy.

The same event may appear as both an AE and a SAE. However, what is presented are distinct events. An event may be categorized as serious in one subject and as nonserious in another subject, or one subject may have experienced both a serious and nonserious event during the study.

Study recruitment was stopped due to difficulty enrolling the target number of participants. There were no safety concerns in the decision to terminate this study.
