作者进行了食管癌热放疗及热放化疗两组前瞻性研究，结果表明，两组的结果均优于单纯放疗。肿瘤控制率与Ｔ９０呈正相关。最近，作者在术中用２４５０ＭＨｚ机行食管腔内微波加热的同时测量瘤内温度，测得有效加温深度为距管腔轴心５ｍｍ处，即腔内肿瘤表面温度升高８℃，... The authors conducted a prospective study of two groups of patients with esophageal carcinoma, thermal radiation and thermal radiation chemotherapy. The results showed that the results of the two groups were superior to radiotherapy alone. Tumor control rate was positively correlated with T90. Recently, the author measured the intratumoral temperature with 2450 MHz intraoperative esophageal microwave heating at the time of surgery. The effective heating depth was measured at a distance of 5 mm from the axis of the lumen, that is, the surface temperature of the tumor in the lumen increased by 8°C. ..
