Given limited data on denosumab (60 mg every 6 months) in premenopausal patients receiving endocrine therapy for early breast cancer, we conducted a retrospective real-world study at the Gemelli Hospital (September 2018\u2013January 2025). A descriptive analysis was performed. The primary endpoint was to assess efficacy, evaluated by changes in bone mineral density via dual-energy X-ray absorptiometry and by monitoring bone turnover markers, particularly serum C-terminal telopeptide of type I collagen. Safety was evaluated based on adverse endocrine therapy events (osteoporotic fractures) and adverse denosumab events (osteonecrosis of the jaw). Sixty-nine patients were eligible for the study. Endocrine therapy included ovarian function suppression with exemestane (89.8%) or tamoxifen (10.1%). Baseline spinal osteoporosis decreased from 20.3% to 5.8%, osteopenia from 39.1% to 34.8%, with normal T-scores rising from 17.4% to 34.8%. Femoral improvements were similar. Serum C-terminal telopeptide of type I collagen levels (evaluated in 35.8%) showed stable reduction in 97%. Denosumab adherence was 89.9%. One osteonecrosis of the jaw case occurred (1.4%); no fractures were reported. Denosumab demonstrated efficacy in improving bone density and reducing bone turnover, with excellent adherence and favorable safety. Longer follow-up is needed to assess post-discontinuation effects.<\/jats:p>","DOI":"10.3390\/curroncol32080421","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T09:53:02Z","timestamp":1753696382000},"page":"421","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Bone
