Primary Outcome Measures:
  • Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed ] [ Designated as safety issue: Yes ]
    Any untoward medical occurrence in a patient who received study drug was considered an adverse event without regard to possibility of causal relationship. An adverse event resulting in any of the following outcomes, or deemed to be significant for any other reason, was considered to be a serious adverse event: death; initial or prolonged inpatient hospitalization; a life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.


Secondary Outcome Measures:
  • Reasons for Discontinuation of Aromasin Therapy [ Time Frame: Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed ] [ Designated as safety issue: No ]
  • Percentage of Participants Who Were Compliant With Treatment [ Time Frame: Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed ] [ Designated as safety issue: No ]
    Compliant with treatment = followed treatment regimen with exemestane according to initial prescription.

  • Duration of Treatment [ Time Frame: Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed ] [ Designated as safety issue: No ]
    Total duration of adjuvant hormonal therapy with exemestane.

  • Event-free Survival [ Time Frame: Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed ] [ Designated as safety issue: No ]
    Event-free survival: time between first intake of exemestane and date of last follow-up or date of death for deceased participants (date of relapse or death or last follow-up minus first intake date) + 1 / 365.25 * 12.


Enrollment: 398
Study Start Date: October 2008
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Postmenopausal ER+ patients treated by Aromasin. Drug: Aromasin
Aromasin 25 mg daily.
Other Name: Exemestane

Detailed Description:

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.

  Eligibility

Ages Eligible for Study:   45 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

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.

Criteria

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.
