[Efficacy of etoposide in bone metastasis of breast cancer].

We have used ADM, MMC, CDDP and other drugs for a case of bone metastasis of breast cancer, but the bone destruction was advanced and she could not walk. We have also used etoposide, a new chemotherapeutic drug, for the same case. Two months later bone sclerosis was seen by X-ray film and pain disappeared. Bone sclerosis then advanced after 6 months, she has begun to stand, and after 8 months she has been able to walk with a cane. There was no severe side effect. Etoposide was very effective for bone metastasis of the breast cancer.
