AbstractInsufficiency fractures are recognised consequences of radiotherapy in gynaecological malignancy with reported incidences between 2.7% and 89%. We aimed to determine the incidence and risk factors for insufficiency fractures in patients receiving radical pelvic radiotherapy for uterine and cervical cancer. A case-note review was undertaken of patients treated between January 2007 and December 2008. Insufficiency fractures were identified from radiographs, computed tomography and magnetic resonance images. Chi-squared and Mann-Whitney tests were performed to determine associations between insufficiency fractures and chemotherapy, steroids and age. A total of 285 patients received pelvic radiotherapy, 137 with uterine and 148 with cervical cancer. Mean age was 59 years. A total of 144 patients received chemotherapy, 101 concurrently and 35 adjuvantly. Bone abnormalities affected 67 patients, 33 had pelvic insufficiency fractures, 12 had multiple fractures and 3 patients developed femoral head avascular necrosis. Use of chemotherapy was not associated with development of fractures (P = 0.949). However, cervical cancer patients had a significantly higher incidence of insufficiency fractures (P = 0.018) and bone pain (P = 0.03) compared with uterine cancer patients. This suggests concurrent chemotherapy may be a significant factor in increasing insufficiency fractures and bone morbidity in these patients and highlights a need for further research to identify, prevent and reduce these long-term complications.
