Romosozumab for cancer treatment-induced bone loss in postmenopausal women with hormone receptor-positive breast cancer: a case series
Abstract
UNLABELLED: Romosozumab was associated with increases in bone mineral density in postmenopausal women with hormone receptor-positive breast cancer and cancer treatment-induced bone loss (CTIBL). No clinical signals of fracture occurrence or cancer recurrence were observed; however, these findings are based on a small retrospective case series and require confirmation in larger prospective studies.
BACKGROUND: Cancer treatment-induced bone loss (CTIBL) is a major complication in postmenopausal women with hormone receptor-positive breast cancer receiving aromatase inhibitor therapy. Although antiresorptive agents are commonly used, some patients continue to experience progressive bone loss or fragility fractures. Romosozumab, a monoclonal antibody against sclerostin, has demonstrated efficacy in postmenopausal osteoporosis; however, clinical data in patients with cancer remain limited.
METHODS: We retrospectively analyzed 22 postmenopausal women with clinically non-metastatic (Stage I-III) hormone receptor-positive breast cancer who received romosozumab for CTIBL at a single institution. Romosozumab was administered for 12 months in patients with progressive bone loss, new fragility fractures, or high fracture risk. All patients received concomitant calcium and/or active vitamin D supplementation. Changes in bone mineral density (BMD), bone turnover markers, and tumor markers (CA15-3, CEA) were evaluated. Differences in skeletal response were also evaluated between…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 22 participants or records.
