- Blastic or mixed blastic/lytic osseous metastases only are evaluable disease provided they are accompanied by an analgesic requirement or a decrease in performance status, and will not require radiation treatment within two cycles from the start of protocol; pure osteolytic disease is evaluable; bone disease must be x-ray proven for the site to be evaluable; patients whose only evidence of metastatic disease is an abnormal bone scan without confirmatory x-rays are not eligible for this study
