放射治疗是非小细胞肺癌重要的局部治疗手段,而治疗失败的主要原因是局部未控或复发。因此,精确的放疗计划的制订是治疗成功的关键,而治疗靶区的确定及精确勾画是最重要的第一步。其中主要包括对大体肿瘤体积原发病灶、大体肿瘤体积阳性淋巴结引流区、临床靶体积、计划靶体积的正确理解及界定。在此对目前非小细胞肺癌的三维适形放射治疗中关于靶区勾画方面予以综述。
Radiation therapy is an important local treatment of non-small cell lung cancer, and the main reason for treatment failure is local uncontrolled or recurrence. Therefore, the development of a precise radiotherapy plan is the key to the success of the treatment, and the determination and precise delineation of the therapeutic target area are the most important first steps. Including the main tumor volume of primary lesions, gross tumor volume positive lymph node drainage area, the clinical target volume, the planned target volume of the correct understanding and definition. This review summarizes the current three-dimensional conformal radiotherapy for non-small cell lung cancer.
