Mean Percentage Change in Lumbar Spine Bone Mineral Density From Baseline (Before Chemotherapy Commencement) to Month 12 of AI Therapy [ Time Frame: Baseline and month 13-18 (1-6 months of chemotherapy + 12 months of AI therapy) ] [ Designated as safety issue: Yes ]

BMD was evaluated at lumbar spine (LS) and hip (HIP) with measurements taken before CT, before AI therapy and at the end of the 12 month followup period while on AI treatment. Dual Energy X-Ray Absorptiometry (DEXA scan) was used with all measurements performed with the Explorer absorptiometer produced by Hologic, Bedford, MA, USA in the same referral site in Athens, apart from two centres in other cities which used however the same absorptiometer model with identical software.

The primary outcome variable was the mean percentage change in LS BMD between the pre CT treatment measurement and the post 12 months AI measurements in the CT cohort. The HT cohort was included as a control group.

Impact of Chemotherapy Followed by Aromatase Inhibitors on Bone Health of Women With ER-positive Early Breast Cancer
Impact of Chemotherapy Followed by Aromatase Inhibitors on Bone Health of Women With ER-positive Early Breast Cancer in Real World Clinical Settings in Greece
The purpose of this study is to identify the combined impact on bone loss as well as the incidence of bone fractures in women with estrogen receptor (ER)-positive, early breast cancer treated with an aromatase inhibitor (AI) either as first line therapy or as maintenance therapy after initial treatment with chemotherapy, in real life clinical settings in Greece.
Subjects with ER-positive early breast cancer will be treated with AIs either as first line therapy or as maintenance therapy after initial treatment with chemotherapy. The total study duration will be 24 months comprising of a recruitment period of 12 months and a follow-up period of 12 months for each participating subject. The primary outcome variable is the mean percentage variation in lumbar spine (LS) bone mineral density (BMD) during the 12 month follow - up period. Measurements will be taken before and after chemotherapy and at the end of the 12 month follow - up period.
