The aim of our study was to evaluate the efficacy of oral clodronate supplementing systemic therapy and/or palliative irradiation in 91 patients with painful bone metastases. Clodronate was administered at a daily dose of 1600-3200 mg for a median of 11 months (range 3-36 months). Partial or complete pain relief was achieved in 61 of 88 evaluable patients (69%). Response rate to clodronate in patients who additionally received palliative bone radiation was similar to that in patients who did not receive irradiation (68 and 71%, respectively). Eleven out of 12 bed-ridden patients with metastatic bone pain regained the ability of walking after the treatment with clodronate. Bone pain relief lasted from 1.5 to 36 months (mean 9.3 months). Clodronate was well tolerated in all but three cases (3%) in whom the treatment was discontinued due to intensive adverse gastrointestinal effects. In conclusion, we observed satisfactory symptomatic effect and low rate of adverse reactions in patients with metastatic bone lesions treated with oral clodronate. Further large controlled studies with thorough patient monitoring are warranted to evaluate the real benefit of clodronate, and to define its optimal scheduling.
