摘要
目的 了解大剂量帕米膦酸二钠治疗前列腺癌骨转移疼痛的疗效及安全性.方法 将100例确诊为前列腺癌骨转移并伴骨痛的患者分为大剂量组、常规剂量组（各50例）,各组分别静脉滴注不同剂量帕米膦酸二钠,大剂量组为第1天90 mg、第2天60 mg,常规剂量组为第1天60 mg、第2天30 mg,每4周重复,共2个周期.观察患者治疗前后疼痛、活动能力、生存质量变化和不良反应情况.结果 治疗后大剂量组的有效止痛率86%（43/50）,明显高于常规剂量组的42%（21/50）,差异有统计学意义（χ2=22.79,P＜0.01）;两组活动能力改善分别为39例（87%）和21例（46%）,生存质量改善分别为33例（66%）和18例（36%）,差异均有统计学意义（χ2值分别为17.04和9.00,均P＜0.01）.均无近期严重不良反应.结论 大剂量帕米膦酸二钠可缓解前列腺癌骨转移所致疼痛,改善患者生存质量.
Objective To study efficacy and safety of large dose of pamidronate disodium in treatment for patients with painful bone metastasis of prostate cancer. Methods A total of 100 patients with painful bone metastasis of prostate cancer were randomized into large dose group and conventional dose group, with 50 cases each. Pamidronate disodium was administered by intravenous infusion, 90 mg on the first day and 60 mg on the second day for large dose group, and 60 mg on the first day and 30 mg on the second day for conventional dose group, respectively, every 4 weeks for two courses. Changes of pain,mobility, quality of life and adverse effect in patients before and after treatment were observed. Results After treatment, pain was relieved in 43 of 50 patients （ 86% ） in large dose group, significantly more than that in conventional dose group （21/50, 42% ） （χ2 = 22.79, P 〈 0. 01 ）. Both mobility and quality of life were improved in 39 and 33 patients （ 87% and 66% ）, respectively in large dose group and 21 and 18 （46% and 36% ）, respectively in conventional dose group （χ2 = 17.04 and 9. 00, P 〈0. 01 ）. No severe adverse effect in both groups was observed. Conclusions Pain in patients with bone metastasis of prostate cancer can be significantly relieved with large dose of pamidronate disodium, as well as their quality of life improved.
