[Clinical analysis of eight cases of bone metastasis of uterine carcinomas].

Objective: To investigate the clinical feature, risk factors and prognosis of bone metastasis from uterine carcinomas.

Methods: Eight cases of bone metastasis of uterine carcinomas in our hospital from Mar 2001 to June 2005 were studied retrospectively. These eight women, aged 35 to 74, suffered from cervical cancer (5/8) and endometrial carcinoma (3/8) respectively.

Results: (1) The interval between diagnosis of primary carcinoma and detection of bone metastases was within 2 years. The average interval was 5.3 months in patients with poorly differentiated tumor, and 21 months in the other patients. (2) Specific pathology type and poorly differentiated carcinomas may be risk factors of bone metastasis. (3) Three patients did not receive therapy of bone metastasis, and died within 6 months. In the other five patients, four are still alive.

Conclusions: The interval between diagnosis of uterine carcinoma and detection of bone metastases is within two years. The most common sites are pelvic bone and vertebrae. Specific pathology type and poorly differentiated carcinomas may be risk factors of bone metastasis. The prognosis of bone metastasis of uterine carcinomas is poor. Treatment of bone metastasis is primarily palliative and may prolong survival.
