采用热电偶测量10例膀胱癌患者在射频热疗期间的肿瘤内、膀胱内和直肠温度。测温结果表明：（1）肿瘤中心区温度为44.5 ± 1.3 ° C，（2）肿瘤边缘区温度为43.6 ±1.0° C，（3）膀胱腔温度为42.9± 1.20 ° C，（4）直肠腔温度为42.4±0.6° C。此外，射频热疗所需的平均输出功率与膀胱内温度和皮下脂肪组织厚度之间存在显著相关性（p <0.01）。
Intratumoral, intravesical and rectal temperatures were measured in 10 patients with bladder cancer during RF-hyperthemia using thermocouples. The temperature measurement study demostrated the temperature distribution as follows: (1)44.5 + 1.3•Ž(mean + SD )in the central area of the tumors, (2)43.6 ±1.0°Cin the tumor margin,(3)42.9±1.20Cin the vesical cavity,(4)42.4±0.6°Cin the rectal cavity.The temperature of the vesical cavity proved to be useful for estimating the tumor margin temperature. In addition, there was a significant correlation (p•ƒ0.01)between the mean output power required for RFhyperthermia and the intravesical temperature, and also the thickness of the subcutaneous fat tissue.
