title: Bone density: is it affected by orchidectomy and radiotherapy given for stage I seminoma of the testis?
abstract: A cross-sectional study of bone density involving 30 patients who had undergone orchidectomy and para-aortic radiotherapy for Stage I seminoma of the testis, has been performed. Bone density measurements were made of the whole body, lumbar spine and hips, including all irradiated areas. Comparison was made with previously obtained standard sex and age matched control data. The 30 patients treated for seminoma had a significantly increased mean bone density compared with age matched normal values. No significant differences were demonstrated between the mean bone densities of the irradiated and non-irradiated hips. There was no significant relationship between bone density measurement and time since orchidectomy or radiotherapy. These results suggest that nodal irradiation for seminoma has little long term effect on bone density.
