  • Title: The Value of Gastric Cancer Staging by Endoscopic Ultrasonography Features in the Diagnosis of Gastroenterology.
    Author: Zhou H, Li M.
    Journal: Comput Math Methods Med; 2022; 2022():6192190. PubMed ID: 35222686.
    Abstract:
    This research was aimed at exploring the application value of endoscopic ultrasonography (EUS) in the diagnosis of gastric cancer staging and the correlation between staging and clinical features of gastric cancer. A total of 72 patients with gastric cancer were selected and randomly divided into two groups. The patients in the pathological group underwent postoperative pathological examination, while those in the EUS group received preoperative EUS examination. The results showed that the staging accuracy of EUS was 73.33% for T1, 78.57% for T2, 27% for T3, and 100% for T4, compared with the pathological staging. The accuracy of N- and N+ was 42.5% and 82.3% in EUS, respectively, and the total accuracy was 55.7%. There was no considerable difference in the accuracy of T staging between early gastric cancer and advanced gastric cancer (P > 0.05), but there was a considerable difference in N staging (P < 0.05). Lymph node metastasis affected the accuracy of N staging (P < 0.05). The number and location of metastatic lymph nodes did not affect the judgment of metastatic lymph nodes (P > 0.05). In addition, the proportion of understaging and overstaging was greatly different among different lesion sizes and histological types of gastric cancer (P < 0.05). To sum up, the accuracy of EUS for T and N staging of gastric cancer needed to be improved. The location of gastric cancer lesions affected the accuracy of T staging, while the depth of invasion and lymph node metastasis affected the accuracy of N staging.
