| | Ninety patients with esophageal cancer were randomized into radiotherapy alone group (R group) or combination of intracavitary microwave hyperthermia group (RM group). In the RM group, radiotherapy was given first through anteroposterior fields to a total dose of 4000 cGy / 4wk. For intracavitary microwave hyperthermia, the temperature on the tumor was maintained at 46±0.5℃for 30 minutes after external radiation, 2-3 times/week, totally for 6-12 times. In the R group, rad... | | 1979年9月至1981年10月治疗90例食管癌,随机分为加温组和单放组各45例。加温组先放疗后加温,加温使瘤体表面保持46±0.5℃,每次30分钟,2~3次/周,6~12次为一疗程。放疗采用前后两野垂直照射D_T40Gy/4周。单放组三时野交叉照射D_T60~70Gy/6~7周。10年生存率加温组为13.3%(6/45),单放组为2.2%(1/45),P<0.05。 | | 文摘来源 | | An insulated water-cooled dipole microwave applicator for intracavitary hyperthermia is analysed. The influence of the applicator' s length to the radiation ampedance and standing wave ratio is discussed according to the current distribution on the applicator. Then, the SAR in the biological tissue around the cavity is calculated. Finally, the influence of the applicator' s length on the temperature field distribution is studied in conformity with the steady state bioheat equilibrium equat... | | 本文分析了一种带冷却水的用于人体体腔内部热疗的绝缘偶极子微波辐射器的特性.利用辐射器上的电流分布导出辐射阻抗和驻波比与辐射器长度的关系式,探讨了体腔周围被加热生物组织中分布的比吸收率(SAR),进而根据热平衡方程得到辐射器长度对温度场分布的影响,为体腔内部热疗用微波辐射器的设计提供了理论依据. | | 文摘来源 | | From May ,1994 to April,1995,98 nasopharyngeal carcinoma Patients (stage ll to IVa)without any anti cancer treatment previously were randomized into the controlled group (radiotherapy alone)and the combined group(intracavitary microwave hyperthermia plus irradiation).The CR rate of the primary lesion in nasopharynx was 95.92%(47/49)for the combined group,and 83.67%(41/39)for the controlled group at end of treatment.The difference between the two group was statistically sinifi cant(p<0.05... | | 1994年5月至1995年4月将98例初治鼻咽癌配对分为腔内微波热疗合并放疗(简称热疗)组与单纯放疗(简称单放)组各49例。间接鼻咽镜与CT近期疗效评价,热放组鼻咽原发灶完全消退率分别为95.92%与68.89%,单放组为83.67%与46.67%(P<0.05),热放组肿瘤缩小1/2与完全消退放射剂量均较单放组明显降低。疗效与加热温度,热疗次数有关,同时亦发现热放组颈淋巴结转移灶完全消退率较单放组高。 | | 文摘来源 | |   | | << 更多相关文摘 |
