A Survey Of Clinical Practice Of Adjuvant Treatment Of Breast Cancer Using Exemestane (Aromasin®) In Postmenopausal Hr+ Patients

Study Overview
=================
Brief Summary
-----------------
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).

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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) | 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. | Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reasons for Discontinuation of Aromasin Therapy |  | Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed | 
| Percentage of Participants Who Were Compliant With Treatment | Compliant with treatment = followed treatment regimen with exemestane according to initial prescription. | Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed | 
| Duration of Treatment | Total duration of adjuvant hormonal therapy with exemestane. | Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed | 
| Event-free Survival | 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. | Baseline, every 6 months until adjuvant hormonal therapy stopped or up to 5 years of therapy completed |
