放射野

结果：同期放射野和非放射野肺组织变化基本一致，主要呈急性及亚急性反应和慢性纤维化反应。

Results : The pathological changes in the lung were similar for radiation and non-radiation fields , mainly acute , sub-acute , or chronic inflammations .

结果：肿瘤控制率为98.2%（112／114），2例（1.8%）在放射野边缘复发。

Results : Objective tumor control rate was 98.2 % ( 112 / 114 ) . There were observed 2 local recurrences ( 1.8 % ) at the border of the field .

因此，综合治疗中，为了既得到好的治疗效果又减少肺部早期放射性反应的发生，对于用阿霉素化疗的病例，我们应该适当控制总照射剂量，精确设计放射野。

To acquire good result and reduce the incidence of early radiation response of the lung , for the patients treated with CAMF regimen , we should control the total radiation dose properly and design the radiation fields precisely .

方法1997年至1999年经病理证实的62例中晚期食管癌，根据CT扫描所获得的不同影像资料，在工作站上经计算机数字化处理，建立三维模拟假体，进行放射照射野的定位设计。

Methods From 1997 to 1999,62 patients with pathologically proved esophageal cancer were studied . The irradiation portals were designed through computer digital processing in the workstation and the three dimensional imitated " pseudobody " was set up on the different imaging data obtained through CT scan .
