Abstract
Included in this study were 43 breast cancer patients treated with adjuvant chemotherapy who presented metastasis only in bone. Forty‐two percent had metastasis during chemotherapy, and 58% had metastasis after the completion of chemotherapy. In 66% of the patients, the lesions were osteolytic. Twenty‐nine percent had osteoblastic lesions, and 5% had mixed lesions. Of the patients with osteoblastic metastatic disease, five showed asymptomatic, osteoblastic disease; this response was considered to be a healing response to chemotherapy. These five patients were continued on the same therapy. The median duration of this response to the adjuvant chemotherapy was 29 months (range 6 to 62+). In one patient, osteoblastic disease gradually faded, and skeletal radiographs reverted to normal.
