Abstract:
Objective:To investigate the clinical value of AB classification combined with Arima classification for predicting the invasion depth of superficial esophageal squamous cell carcinomas (SESCC).Methods:From July 2017 to December 2022, 76 cases of SESCC receiving endoscopic submucosal dissection and intra-epithelial papillary capillary loops (IPCL) AB classification as type B2 in Ningbo Medical Center Lihuili Hospital and Jiangsu Province Hospital of Chinese Medicine were included in the study. IPCL was reclassified according to Arima classification. The depth of infiltration determined by pathology was the gold standard. The sensitivity, the specificity, the positive predictive value and the negative predictive value of B2-Arima combined classification in predicting the invasion depth of SESCC were analyzed.Results:In the 76 cases of type B2 IPCL lesions, 31 cases (40.79%) were T1a-MM/T1b-SM1 SESCC. The sensitivity, the specificity, the positive predictive value, the negative predictive value and the diagnostic accuracy of type B2 IPCL to predict T1a-MM/T1b-SM1 SESCC were 70.45% (31/44), 79.64% (176/221), 40.79% (31/76), 93.12% (176/189), and 78.11% (207/265), respectively. After Arima classification, the above corresponding indicators of type B2-4ML and type B2-AVA-4M IPCL in predicting T1a-MM/T1b-SM1 SESCC were 61.36% (27/44), 88.24% (195/221), 50.94% (27/53), 91.98% (195/212), 83.77% (222/265) and 38.64% (17/44), 94.57% (209/221), 58.62% (17/29), 88.56% (209/236), 85.28% (226/265), respectively.Conclusion:B2 IPCL combined with Arima classification can improve the diagnostic accuracy of T1a-MM/T1b-SM1 ESSCC.
