Bone metastasis from cervix cancer.

Among 713 patients followed after treatment for cancer of the uterine cervix, 48 (6.6%) had a metastasis to the bone. The rates of metastasis in each of the four clinical stages were 11/273 (4.0%) in stage I, 16/243 (6.6%) in stage II, 13/162 (8.0%) in stage III, and 8/35 (22.9%) in stage IV, respectively. The most frequent site of metastasis was the vertebral column, particularly the lumbar spine (23 cases, 48%) followed by the pelvic bones. Pulmonary metastasis also frequently occurred. For 32 (67%), lesions of the bone were detected within 1 year after completion of the initial treatment, and 36 (75%) died within 1 year after detection of the metastasis. Those patients who survived over 2 years were those for whom the lesions of the bone had been treated by radiotherapy followed by chemotherapy.
