目的:探讨放射治疗骨转移癌不同分割方法的止痛效果。方法:37例骨转移癌患者22例采用常规分割照射,DT200 cGY/次,每周5次,总DT3 600～5 000 cGY;15例采用低分割照射,DT300～500 cGY/次,每周3～5次,总DT2 000～3 000 cGY。结果:常规分割放疗组与低分割放疗组止痛效果大致相同,差异无统计学意义(P>0.05)。结论:常规分割放疗和低分割放疗同样可以起到止痛作用。
Objective: To investigate the analgesic effects of different methods of radiotherapy for bone metastases. Methods: Twenty-seven patients with bone metastasis were divided into two groups randomly. DT200 cGY / time was 5 times a week, total DT3 was 600-5000 cGY. Fifteen patients were treated with low-dose radiation and DT300 ~ 500 cGY / ~ 5 times, total DT2 000 ~ 3 000 cGY. Results: The analgesic effects of radiotherapy group and conventional radiotherapy group were almost the same, the difference was not statistically significant (P> 0.05). Conclusion: Conventional radiotherapy and low-radiotherapy can also play a role in analgesia.
