Aromatase inhibitors (AI) are extensively used as adjuvant endocrine therapy in post-menopausal women with hormone receptor-positive early breast cancer (HR+ EBC), but their impact on bone health is not negligible. This work aimed to assess bone loss, fracture incidence, and risk factors associated with these events, as well as the prognostic influence of fractures. We have conducted a retrospective cohort study of women with HR+ EBC under adjuvant therapy with AI, during a 3-year period. Four-hundred-and-fifty-one eligible women were reviewed (median age 68 years). Median time under AI was 40 months. A fracture event occurred in 8.4%, mostly in the radium and femoral neck and in older women (mean 74 vs. 68 years, p = 0.006). Age (OR 1.01, 95% CI 1.01–1.07, p = 0.024) and time under AI (OR 1.02, 95% CI 1.00–1.04, p = 0.037) were independent predictors of fracture, with a fair discrimination (AUC 0.71). Analysis of disease-free survival according to fracture event varied between groups, disfavoring the fracture cohort (at 73 months, survival 78.6%, 95% CI, 47.6–92.4 vs. 95.6%, 95% CI, 91.2–97.8, p = 0.027). The multivariate model confirmed the prognostic impact of fracture occurrence (adjusted HR of 3.17, 95% CI 1.10–9.11; p = 0.032). Bone health is often forgotten, despite its great impact in survivorship. Our results validate the pathophysiologic link between EBC and bone metabolism, which translates into EBC recurrence. Further research in this area may help refine these findings. Moreover, early identification of women at higher risk for fractures is warranted.

Abstract Background The standard adjuvant endocrine treatment for postmenopausal female patients with hormone receptor positive early breast cancer was 5 years of tamoxifen, but recurrence and side effects restrict its usefulness. The aromatase inhibitor (anastrozole or exemestane or letrozole) was compared with tamoxifen for 5 years or started after completing 2-3 years of tamoxifen in postmenopausal female patients diagnosed with early breast cancer at "Ain Shams University Hospitals" Objective The aim of the study was to measure survival outcome and treatment tolerability for postmenopausal females with Hormone Receptor Positive early breast cancer who received adjuvant hormonal treatment with tamoxifen [TAM] only for 5 years versus those who received adjuvant hormonal treatment with tamoxifen [TAM] for 2 years switching to aromatase inhibitors [AI] in the sequential 3 years versus those who received adjuvant hormonal treatment with aromatase inhibitors [AI] solely for 5 years. Patients and methods This study included 100 postmenopausal women with early breast cancer who presented at the Clinical Oncology Department, Ain Shams University, in the interval from January 2010 until December 2015. Conclusion Similar disease free survival and overall survival were observed among the three studied groups. Switching tamoxifen to aromatase inhibitors provides better tolerability in terms of endometrial thickness when compared to 5 years of tamoxifen monotherapy. Patients who administer aromatase inhibitor included in the switching strategy experience less osteoporosis and less generalized bone pain compared to upfront aromatase inhibitor to 5 years. There was a significant improvement of disease free survival (DFS) in human epidermal growth factor receptor 2 (HER 2) negative patients receiving any adjuvant hormonal treatment line for five years in comparison to HER 2 positive patients receiving the same adjuvant hormonal treatment for five years.
