[Bone metastasis of cervical carcinoma after treatment: analysis of 73 cases]

From Jan 1971 to June 1985, 3,943 patients with cervical cancer in stages I-III were treated in our hospital, bone metastasis developed in 73 cases (1.85%). 69.86% (51/73) of the metastasis occurred within 2 years after treatment. The most common site of bone metastasis were the vertebral column and pelvic bone. The more advanced clinical stage, the higher metastasis rate. The metastasis rate of nodular-infiltrative tumor was higher than that of exophytic type and ulcerative type 91.78% (67/73) of these patients died within 18 moths of metastasis with a mean survival of 8.9 months. If radiotherapy and chemotherapy were given, the mean survival can prolonged to 12.8 months. The most common route of bone metastasis was via lymphatics.
