RETRACTED: Bone mineral density of lumbar spine and femur in patients with gynecologic cancer.
Objective To compare the bone mineral density (BMD) of the lumbar spine and femur in postmenopausal women with cervical and endometrial cancer without bone metastasis with that in normal control postmenopausal women Methods We retrospectively analyzed the BMD of the lumbar spine and femur using dual-energy X-ray absorptiometry in 130 patients with cervical cancer, 68 patients with endometrial cancer, and 225 healthy controls. Results The serum levels of calcium, phosphorus, osteocalcin, total alkaline phosphatase and urine deoxypyridinoline were measured in all participants. Age, body mass index, parity and time since menopause were not significantly different between the three groups. The T-scores of basal BMD at the fourth lumbar vertebra (L4) were significantly lower in patients with cervical cancer (- 0.68 ± 0.10) compared to those in the other two groups. Additionally, the incidence of osteoporosis at L4 according to the basal status of bone mass was significantly higher in patients with cervical cancer (10.0%) compared to that in controls (0.4%). Urine deoxypyridinoline levels were significantly higher in patients with cervical cancer compared to those in controls. No differences in basal BMD of the lumbar spine and femur were observed between patients with endometrial cancer and controls, and no significant differences in biochemical markers were detected between patients with endometrial cancer and controls. Conclusion Our results suggest that postmenopausal women with cervical cancer have a lower BMD and are at increased risk of osteoporosis in the lumbar spine before receiving anticancer treatment compared with postmenopausal women with endometrial cancer.
