目的:探讨CT扫描对食管癌淋巴结转移诊断的准确率及CT扫描对预测淋巴结转移患者预后的价值。方法:选择我院收入的行食管癌根治术患者共146例,患者均行CT及腹部彩超,检查者CT及腹部彩超对食管癌淋巴结转移检测的准确率及漏诊率,检测CT淋巴结转移数、CT三分区转移情况及CT最大病变直径等CT检测与食管癌淋巴结转移相关因素。结果:CT淋巴结总检出率显著高于彩超检出率,两组对比差异有统计学意义,P<0.05。CT检测中胸上段、胸中段总检出率显著高于彩超检出率,结果对比差异有统计学意义,P<0.05。所有患者自手术日起计算术后1、3年生存率分别为73.3%(107/146)、47.9%(70/146),CT转移数≥2枚、CT三分区转移<2区、CT最大病变直径≤3cm患者术后生存率较高,结果对比差异有统计学意义,P<0.05。结论:CT对食管癌淋巴结转移诊断率较高,CT转移数、CT三分区转移及CT最大病变直径检测可用于评估患者术后生存率情况。
Objective: To investigate the diagnostic accuracy of CT scan in lymph node metastasis of esophageal cancer and the value of CT scanning in predicting the prognosis of patients with lymph node metastasis. Methods: A total of 146 patients undergoing esophageal cancer radical resection were enrolled in this study. The accuracy and rate of misdiagnosis of lymph node metastasis of esophageal cancer by CT and abdominal ultrasonography, CT and abdominal ultrasonography were examined. The number of CT lymph node metastasis, CT tripartite metastasis and CT maximum lesion diameter and other CT detection and lymph node metastasis of esophageal cancer related factors. Results: The overall detection rate of CT lymph nodes was significantly higher than that of color Doppler ultrasound, the difference between the two groups was statistically significant (P <0.05). The total detection rate of upper thoracic and mid-chest in CT was significantly higher than that of color Doppler ultrasound, the difference was statistically significant (P <0.05). All patients had one-year and three-year survival rates of 73.3% (107/146), 47.9% (70/146), and CT metastasis≥2, respectively The patients with diameter less than 3 cm had higher postoperative survival rate, the difference was statistically significant (P <0.05). Conclusion: The CT diagnosis of lymph node metastasis of esophageal cancer is high, CT number of metastases, CT three-compartment metastasis and CT maximum lesion diameter can be used to assess the survival rate of patients.
