Abstract |
A new experimental method to test the effect of drugs on tumor induced osteolysis using a transplantable bladder tumor (MBT-2) in mice has been designed. The method consists of inoculating tumor cells sc over the calvaria in mice, causing in a local tumor with fragmentation of the bone. This was accompanied by adjacent osteoblastic changes, which were evaluated by X-ray and histological examination. APD, a bisphosphonate derivative, at a dose of 3 mg/kg to 10 mg/kg sc protected the bone by decreasing the extent of osteolysis as judged by the same criteria. This inhibition was obtained without apparent effect on the growth of the bladder tumor in mice.
