OSTEOLYTIC bone metastases occur frequency in patients with advanced malignancy. Breast cancer, the most common malignant disease of women, metastasises to bone more frequently than to any other organ1, and over 80% of patients with advanced breast cancer develop bone metastases 2-4. The cellular and molecular mechanisms of bone destruction in patients with cancer are not clearly understood. It has been postulated that there may be two mechanisms, one which is mediated by osteoclasts and one which occurs independently of osteoclasts5,6. We show here that cultured human breast cancer cells have the capacity to resorb directly in vitro, independently of osteoclast stimulation.
