Cancer-induced bone diseases are often associated with increased bone resor
ption and pathological fractures. In recent years, osteoprotective agents s
uch as bisphosphonates have been studied extensively and have been shown to
inhibit cancer-related bone resorption in experimental and clinical studie
s, The third-generation bisphosphonate, ibandronate (BM 21.0955), is a pote
nt compound for controlling tumour osteolysis and hypercalcaemia in rats be
aring Walker 256 carcinosarcoma,
We have studied the effect of ibandronate given as an interventional treatm
ent on bone strength and bone loss after the onset of tumour growth in bone
. Our results suggest that it is capable of preserving bone quality in rats
bearing Walker 256 carcinosarcoma cells, Since other bisphosphonates have
produced comparable results in man after their success in the Walker 256 an
imal models our findings suggest that ibandronate may be a powerful treatme
nt for maintaining skeletal integrity in patients with metastatic bone dise
ase.
