Abstract

Objective: To explore whether the use of intravenous contrast-enhanced ultrasound (CEUS) can improve the diagnostic accuracy of T stage of gastric cancer on the basis of oral contrast-enhanced ultrasound (OCEUS).

Methods: Eighty-one patients with gastric cancer who underwent preoperative CEUS. Criteria for T staging was AJCC Stage 8th Edition. To compare the diagnostic accuracy, sensitivity and specificity of OCEUS and CEUS for T staging of gastric cancer using pathological results as the gold standard.

Results: There were differences in the diagnostic accuracy of T2 (P = 0.048), T3(P = 0.002) and T4 (P = 0.000) between OCEUS and CEUS. And there was no difference in diagnostic accuracy for T1 (P = 0.118). CEUS significantly improved diagnostic sensitivity and specificity in T3 (42.86% to 61.90% for sensitivity, 86.96% to 93.75% for specificity), and T4 (64.71% to 76.47% for sensitivity, 78.33% to 95.74% for specificity).

Conclusion: Compared with OCEUS, CEUS did improve the diagnostic accuracy of T2, T3, and T4 stages of gastric cancer.

静脉超声造影是否能提高胃癌T期诊断的准确性?

目的:探讨在口服超声造影(OCEUS)的基础上应用静脉超声造影(CEUS)是否能提高胃癌T期的诊断准确性。方法:81例胃癌患者行术前超声造影。T分期标准为AJCC分期第8版。以病理结果为金标准，比较OCEUS和CEUS对胃癌T分期的诊断准确性、敏感性和特异性。结果:在T2 (P = 0.048)、T3(P = 0.002)、T4 (P = 0.000)的诊断准确率上，OCEUS与CEUS存在差异。两组T1的诊断准确率无显著差异(P = 0.118)。超声造影显著提高T3和T4的诊断敏感性和特异性(敏感性42.86% ~ 61.90%，特异性86.96% ~ 93.75%)，敏感性64.71% ~ 76.47%，特异性78.33% ~ 95.74%)。结论:与OCEUS相比，CEUS确实提高了胃癌T2、T3、T4期的诊断准确性。
