title: Bone metastasis in endometrial cancer: evaluation of treatment approaches by factors affecting prognosis.
abstract: OBJECTIVE
  The purposes of this study were to present an endometrial cancer case with a first sign of bone metastasis, and to reveal factors affecting survival and the appropriate treatment methods for bone metastases.
  
  
  METHODS
  A total of 101 case reports that presented with bone metastasis of endometrial cancer were reviewed in this study.
  
  
  RESULTS
  Survival time in the patients without surgical treatment for bone metastasis was found to be 12 months (95% CI = 5.89 - 18.10) and 42 months in patients who underwent surgical treatment in addition to one or more of chemo-radio-hormonotherapies (95% CI = 16.58 - 67.41) (p = .006). Histological type of cancer, extra-osseous metastasis, and lack of surgery were the factors significantly affecting survival (p = 0.012, p = 0.002, and p = 0.038, respectively).
  
  
  CONCLUSIONS
  Histological type and the presence of extra-osseous involvement are important prognostic markers in endometrial cancer patients with bone metastasis. It may be appropriate to implement combination therapies including surgery in the treatment of bone metastases.
