Table 1 Detection rates for gastric cancer and high-grade intraepithelial neoplasia using TUS-OCCA

From: Evaluation of transabdominal ultrasound after oral administration of an echoic cellulose-based gastric ultrasound contrast agent for gastric cancer

Gastric cancer and premalignant lesions Detection rates Total
Group S Group U  
High grade intraepithelial neoplasia 6/6 0/4 6/10 (60 %)
 Stage T1a early gastric cancer 14/14 2/10 16/24 (67 %)
 Stage T1b early gastric cancer 18/18 2/8 20/26 (77 %)
Advanced gastric cancer (stage T2 ~ T4) 146/146 82/82 228/228 (100 %)
Total 184/184 (100 %) 86/104 (83 %) 270/288 (94 %)
  1. TUS-OCCA, transabdominal ultrasound after oral administration of an echoic cellulose-based contrast agent. The difference in the detection rates between Groups S and U (100 % vs. 83 %) was significant (p < 0.05, Fisher’s exact test)
