食管钡餐造影结合CT在评估食管癌放疗疗效中的应用

Application of esophageal barium swallow combined with CT in evaluating the curative effect of radiotherapy for esophageal cancer

目的:观察食管钡餐造影结合CT在评估食管癌放疗疗效中的应用价值。方法:选取2022年3月—2023年8月泰安市肿瘤防治院收治的68例食管癌患者,所有患者均采取肿瘤放射治疗,放疗前及放疗后实施CT检查与食管钡餐造影。应用食管钡餐造影对病灶缓解状况进行分析,通过CT对区域淋巴结短径、淋巴结体积、最大管壁厚度、长径等进行检测,联合CT检查与食管钡餐造影评估放疗后的短期生存率。结果:68例患者中,完全缓解、部分缓解、稳定、进展分别有23例、37例、5例、3例,总缓解率是88.24%。放疗后的淋巴结体积、淋巴结长径和淋巴结短径比放疗前的小,差异有统计学意义(P<0.05),而放疗前、后最大管壁厚度差异无统计学意义(P>0.05)。管壁厚度≤1.12 cm与管壁厚度>1.12 cm的总缓解率差异无统计学意义(P>0.05)。放疗后淋巴长径≤1.57 cm比放疗后淋巴长径>1.57 cm的总缓解率高,差异有统计学意义(P<0.05)。放疗后淋巴结短径≤0.89 cm的总缓解率比放疗后淋巴结短径>0.89 cm的高,差异有统计学意义(P<0.05)。放疗后淋巴结体积≤1.79 cm^(3)的总缓解率比淋巴结体积<1.79 cm^(3)的高,差异有统计学意义(P<0.05)。结论:CT结合食管钡餐在食管癌放疗治疗效果评估中应用效果明显,两者联合对于淋巴结体积、长径和短径与钡餐造影疗效的评估更有价值,值得采纳、推广。

Objective To observe the application value of esophageal barium swallow combined with CT in evaluating the efficacy of radiotherapy for esophageal cancer.Methods A total of 68 patients with esophageal cancer admitted to Tai'an Cancer Prevention and Treatment Hospital from March 2022 to August 2023 were selected,and all patients were treated with radiation therapy,and CT examination and barium swallow were performed before and after radiotherapy.Esophageal barium swallow was used to analyze the remission status of lesions,and the short-term survival rate after radiotherapy was evaluated by CT to detect the short diameter of regional lymph nodes,lymph node volume,maximum esophageal wall thickness,and length diameter.Results Among the 68 patients,23 were completely remission,37 were partially remission,5 were stable,and 3 were progressed,respectively,and the overall response rate was 88.24%.The volume of lymph nodes,the length diameter of lymph nodes and the short diameter of lymph nodes after radiotherapy were statistically small compared with those before radiotherapy(P<0.05),while there was no significant difference in the maximum esophageal wall thickness before and after radiotherapy(P>0.05).There was no significant difference in the total remission rate between the wall thickness≤1.12 cm and the esophageal wall thickness>1.12 cm(P>0.05).The overall response rate of lymphatic diameter≤1.57 cm after radiotherapy was higher than that of lymphatic diameter>1.57 cm after radiotherapy,and the difference was statistically significant(P<0.05).The overall response rate of lymph node shortening≤0.89 cm after radiotherapy was higher than that of lymph node shortening>0.89 cm after radiotherapy,and the difference was statistically significant(P<0.05).The overall response rate of lymph node volume≤1.79 cm^(3) after radiotherapy was higher than that of lymph node volume<1.79 cm^(3),and the difference was statistically significant(P<0.05).Conclusion CT combined with barium swallow has obvious effects in the evaluation of the therapeutic effect of radiotherapy for esophageal cancer,and the combination of the two is more valuable for the evaluation of lymph node volume,long diameter and short diameter and the efficacy of barium swallow,which is worthy of adoption and promotion.
