常规放疗与低分割放疗治疗骨转移癌疼痛的临床观察
Observation on Effect of Conventional Fraction and hypo Fraction Radiotherapy in Treating bone Metastases Patients
【摘要】 目的观察常规放疗与低分割放疗治疗骨转移癌疼痛的临床疗效。方法90例患者分2组,常规放疗组45例:采用常规分割照射,DT200cGy/次,每周5次,DT3000~5000cGy;低分割放疗45例:采用低分割照射,300~500cGy/次,每周3~5次,DT2000~3600cGy。结果放疗起到了明显的止痛作用,常规分割放疗组与低分割放疗组止痛效果大致相似,差异无显著性(P>0.05)。结论骨转移癌的放射治疗应根据病情来决定:对一般情况好,预计生存期长的患者应积极给予全剂量的分割治疗,而对于病情相对较重、行动不方便、预计生存期短的患者,应采取低分割照射,同样可以起到止痛作用。
【Abstract】 Objective To observation the pain relief efficacy with conventional fraction and hypo fraction radiotherapy for bone metastases.Methods Of 90 patients with bone metastases , 45 cases received conven- tional fraction : DT200cGy/f,5 fractions per week DT3000~5000cGy.45 cases received hypo fraction : DT300~ 500cGy/f,3~5 fraction per week, DT2000-3600cGys.Results Radiotherapy can produce a higher pain relief rate of bone metastases . Compared conventional fraction with hypo fraction, no significant difference was found (P>0.05).Conclusion Radiotherapy of bone metastases should be determined by the patient condition. For the patients with long life span should be treated actively by conventional fraction and high doses . The patients with severe disability and pain should be treated with hypo fraction.
