RETRACTED: Different bone mineral density in cervical and endometrial cancer.

: Objectives Patients with cervical cancer have lower bone mass than women without cancer, whereas women with endometrial cancer have higher bone mineral density (BMD) than control subjects, possibly due to the prevalence of high body-fat mass. The aim of this study was to compare BMD in patients with cervical cancer, endometrial cancer and controls. Methods We analyzed and compared spinal and femoral BMD in 130 patients with cervical cancer, 68 with endometrial cancer, and 140 age-matched menopausal female control subjects. We also compared serum calcium, phosphorus, total alkaline phosphatase, osteocalcin, and urinary deoxypyridinoline levels. Results Compared with the control group, T-scores for some lumbar vertebrae (L4), the femoral neck, and Ward's triangle were lower in patients with cervical cancer, whereas only L4 T-scores were significantly lower in patients with endometrial cancer. Deoxypyridinoline levels were significantly lower in women with endometrial cancer (p < 0.002) than in women with cervical cancer, but no other biochemical variables differed among groups. Conclusions Cervical cancer was associated with lower BMD, especially in femoral BMD, and may be a risk factor for secondary osteoporosis. However, endometrial cancer generally seemed to have no damaging effect on bone except at L4. A further larger follow-up study in more populations is required to clarify these findings.
