目的 探讨食管痛CT扫描对放射治疗的指导作用。方法 165例食管痛患者放疗前作了CT扫描,对病变部位,长度、纵隔软组织影最大宽度、异常肿大的淋巴结、受侵部位逐一记录并综合分析。结果 病变越长,软组织影最大宽度增大;淋巴结转移占35.15％(58/165),外侵占87.27％(144/165)。结论 食管癌放疗前应常规作CT扫描以明确放疗范围:病变长度、宽度、转移淋巴结、外侵部位,且CT片可直接输入“T.P.S”(Treatmant Planning System)进行放疗计划的设计、优化。
Objective To explore the guiding role of CT scans for esophageal pain in radiation therapy. Methods A total of 165 patients with esophagealgia underwent CT scan before radiotherapy. All the lesions, length, maximum width of mediastinal soft tissue shadow, lymph nodes with abnormal enlargement, and site of invasion were recorded and analyzed comprehensively. Results The longer the lesion, the greater the width of the soft tissue shadow; lymph node metastasis accounted for 35.15% (58/165), and external invasion accounted for 87.27% (144/165). Conclusion Before radiotherapy for esophageal cancer, CT scanning should be routinely used to determine the radiotherapy range: lesion length, width, lymph node metastasis and extravasation site. CT film can be directly input “T.P.S” (Treatmant Planning System) to design and optimize radiotherapy plan.
