微波聚束与射频两种热疗临床比较及分析

Comparison and analysis of the efficacy of microwave focus hyperthermia and radiation frequency hyperthermia on malignancies

目的:比较与分析微波聚束和RF-8射频两种热疗对胸腹部恶性肿瘤的治疗效果,以及患者的血压、心率、升温速率及皮肤反应。方法:从2000年1月￣2005年12月,使用微波聚束热疗机或RF-8射频热疗机进行深部肿瘤加温配合放射治疗,共计90例。对每次加温治疗的疗效以及治疗中患者的血压、心率、升温速率及皮肤反应进行统计分析。结果:微波聚束治疗效果好于RF-8射频热疗,两种加温治疗机对心率、血压的影响没有明显差别,RF-8射频热疗机比微波聚束热疗机的治疗温度上升速度快,诱导期短,微波聚束热疗机治疗时对患者的毒副作用明显小于RF-8射频热疗机。结论:两种热疗配合放射治疗均对肿瘤有明显的治疗效果,微波聚束热疗结合放疗的疗效相对较好。

To compare and analyze the efficacy of microwave focus hyperthermia and RF-8 hyperthermia on chest and abdominal malignancies,and the conditions of patients＇ blood pressure,heart rate,temperature accelerating rate and skin reaction were obseroed during treatment.Methods：From January 2000 to December 2005,90 cases of chest and abdominal malignancies were treated with radiotherapy accompanied with hyperthermia using microwave focus heating machine or RF-8 thermotron.The efficacy of hyperthermia,patients＇ blood pressure, heart rate,temperature accelerating rate and skin reaction during treatment were recorded and analyzed statistically.Results：The efficacy of microwave focus hyperthermia was better than that of RF-8.There was no significant difference between the two types of treatment on patients＇ heart rate and blood pressure. However,the temperature accelerating rate of RF-8 was quidker than that of microwave focus machine,while the side effect of the latter was fewer than that of RF-8.Conclusion：Both type of hyperthermia had treatment effect on malignant tumors,and microwave focus hyperthermia was a better one.
