Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Global incidence of endometrial changes during the adjuvant treatment with Anastrozole [ Time Frame: From inclusion to treatment end(5 years duration) measurements will be taken annually, with a further assessment 12 months after end of treatment. ]

Secondary Outcome Measures:
  • To describe the endometrial changes both clinically(vaginal bleeding) and through the scan. [ Time Frame: During the study, at least annually ]
  • Histological assessment when indicated(type of hyperplasia) [ Time Frame: When applicable ]
  • To assess global incidence of endometrial changes in this patient population before taking Anastrozole [ Time Frame: During the study ]
  • To evaluate type of surgery required for endometrial changes control(hysterectomy rate) [ Time Frame: During the study ]
  • To assess treatment tolerability [ Time Frame: During the study ]
