The effectiveness of CT scanning in radiotherapeutic treatment planning was evaluated in 32 patients with bronchogenic carcinoma. CT of the chest in pretreatment evaluation of these patients supplemented conventional clinical and radiographic patients supplemented conventional clinical and radiographic studies, resulting in (1) more clear delineation of tumor extent in 24 patients (75%); (2) change in assessment of the size of lesions in 14 patients (43%); (3) change of disease stage in 13 (40%); (4) demonstration of inadequacy of treatment plan in nine (28%); and (5) changes in the volume of normal tissue irradiated in 14 (40%). CT scan data was judged essential for treatment planning in 17 patients studied (53%). Unsuspected areas of tumor involvement were seen in 21 patients (65%). Use of the CT scan as a patient contour for radiotherapy treatment planning of lung cancer and alternative techniques are discussed.
对32例支气管癌患者评估了CT扫描在放射治疗计划中的有效性。对这些患者进行治疗前评估时的胸部CT补充了传统的临床和放射学检查，结果显示：（1）24例患者（75%）的肿瘤范围更清晰；（2）14例患者（43%）的病变大小评估有变化；（3）13例患者（40%）的疾病分期有变化；（4）9例患者（28%）显示治疗计划不充分；（5）14例患者（40%）的受照射正常组织体积有变化。在所研究的17例患者（53%）中，CT扫描数据被判定对治疗计划至关重要。21例患者（65%）发现了未被怀疑的肿瘤受累区域。讨论了将CT扫描用作肺癌放射治疗计划的患者轮廓以及替代技术。
